Description

The group of utility models relates to sports carpets used in universal sports halls for practicing in particular martial arts, gymnastics, sports dancing, general physical training, mainly at general education physical education lessons in schools.

According to the object of the utility model “sports carpet” (option 1), a sports carpet containing mats and coverings is known (see the website of CJSC AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru and the website of OKTAKEM company www .oktakem.ru. E-mail: market@oktakem.ru). It is given as an analogue for its intended purpose, since it is the most common design of sports carpets used.

Its advantage is that the assembly, moving and disassembling according to physical abilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 30 minutes. due to the piece-wise alternate assembly and movement of the mats, the number of which in the sports carpet 10 m × 10 m is 50 pieces.

Tatami mats are known that contain mats with individual coatings and bases in the form of covers connected to the mats (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru, and the website of OKTAKEM www.oktakem .ru. E-mail: market@oktakem.ru).

They are given as an analogue for their intended purpose, since they are the most common design of sports carpets.

The advantage is that the assembly, movement and disassembly of the tatami according to physical capabilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 25 ... 30 minutes due to piece-wise alternate assembly and displacement of mats, the number of which in the tatami 10 m × 10 m is 50 pieces.

A sports carpet is known that contains a synthetic blanket, a base connected with it, mats placed between them, bonded to the base, the base made of rubber-cord fabric, and metal plates fixed to the edge parts of opposite sides of the base (see A.S. SU No. 622472, class A63B 5/18, 1978).

The advantage is that physical movements are not required for its movements, since the movements are carried out by winches.

An advantage is also the minimum time required to prepare it for classes and moving to a storage place after classes, estimated at no more than 5 minutes.

The reason for a significant reduction in time is that the mats, the base and the bedspread are interconnected, forming a single whole, which allows the sports carpet to be wound on the drum as a rolled material, so the sports carpet is laid and moved in assembled form, as a result, time for piece-wise alternating is eliminated assembly and movement of mats.

The disadvantage is the movement of the sports carpet by sliding with support on the floor of the gym, as a result of which even a base made of rubber-cord fabric after several tens of movements will be destroyed by friction on the floor. Also, the paintwork of the floor and the layout of the playing fields will be destroyed.

The disadvantage is the need for a niche in the floor of the gym or the need for a drum with a diameter of approximately 500 mm and a length of more than 10 m.

As a result of these shortcomings, this sports carpet did not find practical application.

The closest device to the claimed utility model is “Covering on a gymnastic carpet”, containing strips of rolled PPE (polyethylene foam) measuring 2 m × 14 m and a thickness of 35 mm and 42 mm with carpets connected to them (see the website of ZAO AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru).

For transportation, PPE strips are rolled into rolls with an outer diameter of approximately 1 m, and at the place of use, they are rolled out and fastened with Velcro contact tape.

The advantage is that instead of mats, a roll-on PPE is used, which eliminates the piece-by-piece assembly and movement of mats, replacing them with assembly, moving and disassembling by rolling. This should significantly reduce the time required to prepare for classes and the release of the playground after classes.

The disadvantage is that for rolling each PPE strip into a roll, significant, depending on the width of the PPE strip, physical efforts of several at least two athletes are required, especially when forming the first and second turns, to stabilize the rolling process.

Significant efforts are needed to overcome the resistance of the PES strip to bending, while the greater the thickness of the PES strip, the greater the resistance to bending (the shock-absorbing properties of the PES, including the density in kg / m3 and the PES strip width, are assumed to be conditionally constant).

The second drawback is that the actions of athletes when rolling the PES strip, especially the first and second turns to stabilize the rolling process, must be carried out in a strictly coordinated manner.

This is necessary for the following reasons:

- for shaping the first and second turns by sequential and simultaneous impact on the PES band of two athletes at different points and directions in the conditions of overcoming the resistance of the PES band to bending;

- to ensure the cylindricality of the first turn, which determines the straightness of the further rolling of the PPE roll, including straightening and adjusting the non-linearity of rolling, arising due to the uneven bending of the first turn along the width of the PPE strip in the form of a wave-like end face of the PPE strip in the places of point application of hand efforts;

to ensure the formation of the smallest possible diameter of the first turn, which determines the diameter of the rolled roll and the required area for its storage;

- to ensure the fixation of the first turn and the constant pressing of the formed PPE coils to the straight-rolled straight part of the PPE strip lying on the floor to prevent it from springing under the influence of shock-absorbing properties with the formation of gaps between the coils during the whole rolling process. In this case, the springing occurs either by rolling, or, when the athletes counteract the rolling, sliding of the coils relative to and inside each other with an increase in diameters and the formation of gaps between the coils as a result.

The existing agreed procedure for the actions of athletes when rolling down the PES strip (in stages) is as follows:

- the first athlete, who is outside the PES strip, facing him, raises the edge of the PES strip with a change in direction along arrow A to a height of about 1 meter, while bending the PES strip by about 90 degrees;

- the second athlete, who is on the PES strip facing towards its edge, grabs the raised edge of the PES strip and bends it with a change in direction along arrow B by approximately 90 degrees, since he cannot bend the PES strip by a larger angle due to the slipping of the PES strip from hands under the action of springing forces and holds the PES strip in this position;

- the first athlete clicks on the PES strip with a change of direction in arrow A, while the second athlete presses on the edge of the PES strip with a change of direction in arrow B, presses the edge to the PPE strip, fixes it and checks the cylindricality of the first turn;

- both athletes make the previous step several times to correct the non-cylindricity of the first turn, which determines the further straightness of rolling, form the minimum possible diameter and the beginning of the second turn;

- the first and second athletes click on the PPE strip in the direction of arrows A and B, form a second loop and roll the PPE strip into a roll.

The presence of these disadvantages is clearly, but to a much lesser extent, manifested during the experimental rolling of a sheet of drawing paper "whatman", especially on the long side.

As a result of the total effect of the shortcomings, the time required to roll the PPE strip into a roll increases significantly, therefore, roll PPE is used only for the manufacture of stationary shock-absorbing coatings in specialized halls and such coatings are not intended for repeated rolling, moving and rolling within one day in universal sports halls, for example, in school gyms at general education physical education lessons.

The essence of the claimed utility model is as follows.

In the "Federal component of the state standard of general education", approved by order of the Ministry of Education of the Russian Federation on 05.03.2004, No. 1089, in the section "Training and Practical Equipment" in clause 5.24 it is indicated "Coating for wrestling carpet", and in clause 5.25 it is indicated "Mats wrestling ". Consequently, comprehensive schools in physical education lessons should conduct training for students in various types of martial arts.

But, even with the indicated mats and blankets, schools are not able to include martial arts and other sports with the use of sports carpets in the curriculum, since the time of their assembly, movement and disassembly is more than 25 ... 30 minutes (more than 25% of the training time lesson).

It is impossible to use coatings from rolled PES due to time constraints, and because of the complex, requiring considerable physical effort and actions in an agreed order process of rolling strips into rolls, a process difficult for schoolchildren, at least at primary and secondary schools.

Therefore, it is impossible to use well-known sports carpets, tatami, coverings from rolled PPE in the school schedule mode of physical education classes, which involves alternating classes on a sports carpet, for example, wrestling, and classes in the next lesson in game sports, for example, basketball, in one gym. Therefore, they have their schools either in stationary specialized halls with a room of more than 100 m2, or for demonstration purposes.

The problem the utility model aims to solve is to develop a sports carpet based on a roll of shock-absorbing material with the possibility of using it in the school schedule mode, for which it must meet the requirements:

- the time of rolling, moving and rolling the sports carpet should be no more than 5 ... 6 minutes;

- the efforts of rolling, moving and rolling the sports carpet should be accessible to the physical abilities of schoolchildren;

- the agreed procedure for the action of athletes when rolling should be simplified by technical means, which will increase the convenience of using a sports carpet.

The technical results that will be achieved when these requirements are met, eliminate some of the above causes of deficiencies and are as follows:

- reducing the resistance of the roll of shock-absorbing material to bending without reducing its shock-absorbing properties;

- ensuring cylindrical and straightforward rolling with technical means;

simplification of providing the smallest possible diameter of a rolled roll;

- improving the usability of sports carpet by supplying it with technical means.

The total technical result is as follows:

- expansion of the arsenal of sports carpets for classes in universal sports halls, including physical education classes in secondary schools in the mode of the school lesson schedule.

The specified technical results in the implementation of the utility model are achieved by the fact that in the well-known sports carpet containing a roll of shock absorbing material and a cover, the feature is that the roll of shock absorbing material is equipped with at least one row of structural elements for local reduction of bending resistance with the possibility of rolling, rolling and moving the sports carpet by rolling.

In addition, the structural elements are made in the form of grooves of a V-shape in the upper part of the roll of shock-absorbing material with a depth of part of the thickness of the roll of shock-absorbing material.

In addition, the roll cushioning material is inseparably connected to the bedspread.

In addition, the structural elements are made in the form of grooves of a V-shape in the upper part of the roll of shock absorbing material with a depth of the thickness of the roll of shock absorbing material, while the roll of shock absorbing material is connected to an additional base.

In addition, the structural elements are made in the form of cuts in the lower part of the roll cushioning material with a depth of part of the thickness of the roll cushioning material.

In addition, structural elements are made in the form of cavities inside a roll of shock-absorbing material.

In addition, the structural elements are made in the form of holes and / or grooves with a depth of part of the thickness or the thickness of the roll of shock-absorbing material.

The first row of structural elements in the form of grooves, cuts, cavities, holes and / or grooves is located at a distance of 50 mm to 300 mm from the edge of the roll of shock-absorbing material, and the rest are arranged in increments of 50 mm to 300 mm.

The step is made variable.

In this case, the depth is made variable.

In this case, the angle of the V-shaped groove is made variable.

Moreover, structural elements in the form of grooves, cuts, cavities, holes and / or grooves are located in the working area and / or outside the working area of the sports carpet.

In addition, the structural elements are made in the form of the edge of a roll of shock-absorbing material with a reduced thickness.

In addition, the structural elements are made in the form of inserts from a material with less bending resistance in the upper or lower part of the roll of shock-absorbing material.

The essential feature of "structural elements for local reduction of the bending shock absorbing material of the shock-absorbing material" is in a causal relationship:

- with the technical result of “reducing the resistance of the rolled shock-absorbing material to bending without reducing its shock-absorbing properties”, since the structural elements are located locally, in the form of lines of least resistance to bending, and come into effect only when the sports carpet is bent along these lines for rolling. In the carpet rolled on the floor of the gymnasium, the structural elements practically do not reduce the cushioning properties under vertical load, for example, from the athlete’s foot, since this load is perceived through a common blanket, just like in the analogue at the joints of mats with the inevitable gaps between them, formed when laying;

- with the technical result “ensuring cylindricality and straightness of rolling by technical means”, since the structural elements are a technical means that provides bending of the shock-absorbing material when rolling along the lines of least resistance to bending, without requiring special actions by athletes in a strictly coordinated manner. In this case, the structural elements provide the shaping of the first and second turns in the form of a regular polyhedron, which ensures the straightness of rolling;

- with the technical result of “simplifying the provision of the smallest possible diameter of the rolled coil”, since the structural elements provide the rolling of shock-absorbing material in the first turn into a regular polyhedron, which makes it possible to direct the necessary efforts and attention to ensuring the minimum possible diameter of the first turn and, therefore, obtaining the minimum the possible diameter of the rolled roll to reduce the required storage space;

- with the technical result “improving the usability of the sports carpet by supplying it with technical means”, as it eliminates the repeated steps of the athletes in forming cylindricality, the minimum diameter of the first turn and ensuring the straightness of rolling with technical equipment - structural elements;

- with the total technical result “expansion of the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule”, as a result:

- reduces the time of rolling, moving and rolling sports carpet up to 5 ... 6 minutes, which is acceptable for use;

- makes the order of rolling, moving and rolling sports carpet accessible to the physical abilities of students.

An essential feature in particular cases of execution allows you to get additional technical results:

- the implementation of structural elements in the form of grooves of a V-shape in the upper part of the roll of shock-absorbing material with a depth of part of the thickness of the roll of shock-absorbing material made it possible to connect it to the bedspread, for example, by gluing. Therefore, the blanket is rolled up together and simultaneously with the shock absorbing roll material, which allows to obtain an additional technical result "additional reduction in the time of rolling and rolling the sports carpet." In the presence of grooves, the bending of the shock-absorbing material takes place along the lines of least resistance, and the gaps between the grooves are practically not bent, that is, a polyhedron with straight faces is formed and the adhesive layer does not undergo destructive deformations on the faces, while the parts of the surface of the cover above the grooves are folded and enter the grooves. Without grooves, the bending occurs uniformly around the circumference, while the inner layer of the roll cushioning material and, accordingly, the cover glued to it, compress and reduce its length, but since the elastic properties of the material of the cover (PVC) and the roll of cushioning material are different, they shift relative to each other and the separation of the bedspread. Therefore, in the prototype in the "Rules of storage and transportation", paragraph 2, it is stated: "Coatings are rolled up with a carpet layer to the outside."

- the implementation of structural elements in the form of grooves of a V-shape in the upper part of the roll of shock-absorbing material with a depth of the thickness of the roll of shock-absorbing material with a connection with an additional base made it possible to use this constructive element with its changing step when laying the sports carpet with the base up to obtain additional technical The result is “assembly, disassembly and transportation of the sports carpet by folding”.

The essential feature of “at least one row of structural elements” is in causal connection with the technical results, since even one row of structural elements provides bending of the shock-absorbing material along the line of least resistance and the formation of the first turn, which determines the further straightness of rolling.

The essential attribute “structural elements” is expressed in a generalized form, since various forms of its implementation by various structural elements are possible, including:

- with a local decrease in the thickness of the roll of shock-absorbing material with grooves, cuts and along the edge of the roll of shock-absorbing material;

- without changing the thickness of the roll of shock-absorbing material with local cavities, holes and / or grooves, inserts with the same technical results.

The name of the utility model “Sports Carpet” was chosen because the supply of the roll of shock-absorbing material with grooves, or holes and / or grooves, inserts entails the obligatory covering with a blanket to eliminate cracks and voids on the surface of the roll of shock-absorbing material.

Information confirming the possibility of implementing a utility model with obtaining the above technical results are as follows.

A sports carpet includes a roll of cushioning material 1, for example, rolled PPE (polyethylene foam) or PVV mats (secondary foaming polyurethane), glued to a common base, general blanket 2 made of PVC (polyvinyl chloride), used in special cases, additional base 3, structural elements for local changes in the resistance of the strip to bending in the form:

- grooves 4 with a depth of part of the roll cushioning material 1, grooves 5 with a depth of the thickness of the roll cushioning material made by cutting or molding with a heated tool to the melting temperature of the roll cushioning material 1;

- cuts 6 deep on a portion of the roll of cushioning material 1;

- cavities 7 inside the roll cushioning material,

made by molding with a heated tool to the melting temperature of a roll of shock-absorbing material, followed by gluing the layers together;

- holes 8 in depth per part of the roll cushioning material 1, holes 9 deep in the thickness of the roll cushioning material 1, grooves 10 in depth for a part of the thickness of the roll cushioning material 1, grooves 11 in depth for the thickness of the roll cushioning material 1, made by cutting or molding with a heated tool up to the melting temperature of the roll cushioning material;

- edges with a reduced thickness of 12, made by gluing a roll of shock-absorbing material of different lengths;

- inserts 13 from a material with lower bending resistance, made by molding with a heated tool to the melting temperature of the roll-cushioning shock-absorbing material of the places for inserts with gluing the inserts;

Roll up, move and roll out the sports carpet as follows.

Athletes disconnect the blanket 2, connected along the perimeter of the sports carpet with shock absorbing material 1, using one of the known compounds, for example, Velcro contact tape (not shown in the figures), roll the blanket 2 into a roll and move it by rolling to the wall of the gym to the storage place .

Then the athletes roll the roll cushioning material 1 into a roll.

In this case, bending occurs along the lines of arrangement of structural elements, that is, along the lines of least resistance to bending, therefore, athletes can exert significantly less effort.

In addition, the roll cushioning material 1, bending, forms a regular polygon, which ensures the cylindricality of the first turn and the straightness of rolling, as well as the smallest possible diameter of the roll.

In the particular case of the construction of the structural element in the form of an edge with a reduced thickness 12, the formation of a regular polygon does not occur, but due to the reduced thickness of the edge for the formation of the first turn, athletes can apply significantly less effort, and therefore direct the released forces to ensure cylindrical and straightforward rolling , as well as the smallest possible diameter of the rolled roll.

Special cases of structural elements:

- with a step from 50 to 300 mm;

- with a step varying within these limits;

- with a varying depth of grooves;

- with a varying angle of the V-grooves are provided for the possibility of choosing the parameters of structural elements depending on:

- from the turn number, since with each subsequent turn, the diameter of the turn increases by two thicknesses of the shock-absorbing roll material 1, which means that the degree of deformation decreases, therefore, the step can be increased, the depth reduced, the angle of the V-shaped groove reduced.

- from the thickness of the roll cushioning material 1, since the smaller the thickness, the larger the pitch, the smaller the depth of the grooves, the smaller the angle of the V-shaped groove.

- from the density of the roll cushioning material 1, since the higher the density, the smaller the pitch should be, the greater the depth of the grooves, the larger the angle of the V-shaped groove.

Preferred for the use of structural elements for local reduction of the resistance of the roll cushioning material 1 to bending are materials:

- rolled PES (chemically or physically crosslinked, see the INTEM website www.intem.mpi.ru), up to 30 mm thick and up to 40 kg / m ³ density.

- PPV mats with a thickness of up to 40 mm and a density of up to 160 kg / m ³ glued to a common base.

With an increase in the thickness and density of these materials, the bending resistance increases by so much that makes it difficult to use them for sports carpets using rolling.

The effort that you need to make to roll, for the most part, determines the weight of the sports carpet. It consists of the weight of a PVC blanket equal to 75 kg with a size of 10 m × 10 m and the weight of a roll of shock-absorbing material equal to 105 kg with a size of 0.035 m × 10 m × 10 m. The total weight of a sports carpet is approximately 180 kg. With a rolling friction coefficient of 0.3 for rolling a sports carpet, it is necessary to develop a total force of 0.3 × 180 kg = 54 kg, that is, each of the 20 athletes must develop a force of 2.7 kg, which is available to elementary school students.

In the manufacture of sports carpet made of PVC (secondary polyurethane foaming), the total weight will be approximately 550 kg, therefore, each of the 20 athletes must develop an effort of 8.25 kg, which is available to elementary school students.

Then the athletes fix the rolled up roll, for example, by a cord connection and move it by rolling to the wall of the gym to the storage place.

Rolling the roll and laying the coverlet 2 is carried out in the reverse order.

According to the object of the utility model “sports carpet” (option 2), a sports carpet is known that contains mats and coverings (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM company www .oktakem.ru. E-mail: market@oktakem.ru).

It is given as an analogue for its intended purpose, since it is the most common design of sports carpets used.

Its advantage is that the assembly, moving and disassembling according to physical abilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 30 minutes. due to the piece-wise alternate assembly and movement of the mats, the number of which in the sports carpet 10 m × 10 m is 50 pieces.

Tatami mats are known that contain mats with individual coatings and bases in the form of covers connected with mats (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM www.oktakem.ru E-mail: market@oktakem.ru).

They are given as an analogue for their intended purpose, since they are the most common design of sports carpets.

The advantage is that the assembly, movement and disassembly of the tatami according to physical capabilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 25 ... 30 minutes due to piece-wise alternate assembly and displacement of mats, the number of which in the tatami 10 m × 10 m is 50 pieces.

A sports carpet is known that contains a synthetic blanket, a base connected with it, mats placed between them, bonded to the base, the base made of rubber-cord fabric, and metal plates fixed to the edge parts of opposite sides of the base (see A.S. SU No. 622472, class A63B 5718, 1978).

The advantage is that physical movements are not required for its movements, since the movements are carried out by winches.

An advantage is also the minimum time required to prepare it for classes and moving to a storage place after classes, estimated at no more than 5 minutes.

The reason for a significant reduction in time is that the mats, the base and the bedspread are interconnected, forming a single whole, which allows the sports carpet to be wound on the drum as a rolled material, so the sports carpet is laid and moved in assembled form, as a result, time for piece-wise alternating is eliminated assembly and movement of mats.

The disadvantage is the movement of the sports carpet by sliding with support on the floor of the gym, as a result of which even a base made of rubber-cord fabric after several tens of movements will be destroyed by friction on the floor. Also, the paintwork of the floor and the layout of the playing fields will be destroyed.

The disadvantage is the need for a niche in the floor of the gym or the need for a drum with a diameter of approximately 500 mm and a length of more than Hume.

As a result of these shortcomings, this sports carpet did not find practical application.

The closest device to the claimed utility model is “Covering on a gymnastic carpet”, containing strips of rolled PPE (polyethylene foam) measuring 2 m × 14 m and a thickness of 35 mm and 42 mm with carpets connected to them (see the website of ZAO AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru).

For transportation, PPE strips are rolled into rolls with an outer diameter of approximately 1 m, and at the place of use, they are rolled out and fastened with Velcro contact tape.

to ensure the formation of the smallest possible diameter of the first turn, which determines the diameter of the rolled roll and the required area for its storage;

- both athletes make the previous step several times to correct the non-cylindricity of the first turn, which determines the further straightness of rolling, form the minimum possible diameter and the beginning of the second turn;

- the first and second athletes click on the PPE strip in the direction of arrows A and B, form a second loop and roll the PPE strip into a roll.

Consequently, comprehensive schools in physical education lessons should conduct training for students in various types of martial arts.

But, even with the indicated mats and cover, schools are not able to include martial arts and other sports with the use of sports carpets in the curriculum, since the time of their assembly, movement and disassembly is more than 25 ... 30 minutes (more than 25% of the lesson’s training time) .

It is impossible to use coatings from rolled PES due to time constraints, and because of the complex, requiring considerable physical effort and actions in an agreed order process of rolling strips into rolls, a process difficult for schoolchildren, at least at primary and secondary schools.

Therefore, it is impossible to use well-known sports carpets, tatami, coverings from rolled PPE in the school schedule mode of physical education classes, which involves alternating classes on a sports carpet, for example, wrestling, and classes in the next lesson in game sports, for example, basketball, in one gym. Therefore, they have their schools either in stationary specialized halls with a room of more than 100 m2, or for demonstration purposes.

The problem the utility model aims to solve is to develop a sports carpet based on a roll of shock-absorbing material with the possibility of using it in the school schedule mode, for which it must meet the requirements:

- the time of rolling, moving and rolling the sports carpet should be no more than 6 ... 7 minutes;

- the efforts of rolling, moving and rolling the sports carpet should be accessible to the physical abilities of schoolchildren;

- the agreed procedure for the athletes when rolling should be simplified by technical means, which will increase the convenience of using a sports carpet.

The technical results that will be achieved when these requirements are met, eliminate some of the above causes of deficiencies and are as follows:

- reducing the resistance of the roll of shock-absorbing material to bending without reducing the shock-absorbing properties of the sports carpet;

- simplification of the provision of cylindricality and straightness of rolling;

simplification of providing the smallest possible diameter of a rolled roll;

- improving the usability of sports carpet by supplying it with technical means.

The total technical result is as follows:

- expansion of the arsenal of sports carpets for classes in universal sports halls, including physical education classes in secondary schools in the mode of the school lesson schedule.

The specified technical results in the implementation of the utility model are achieved by the fact that in the well-known sports carpet containing a roll of shock absorbing material and a cover, the feature is that the roll of shock absorbing material is made of at least two layers not connected to each other with the possibility of separate rolling, rolling and rolling movements of layers of a sports carpet by rolling.

In addition, the layers of roll cushioning material are made with the same or different cushioning properties.

In addition, the layers of roll cushioning material are made of the same or different thickness.

In addition, the layers of roll cushioning material are made of different materials.

In addition, the layers of roll cushioning material are arranged in mutually perpendicular directions.

The essential sign "made ... of two unconnected layers with the possibility of separate rolling ..." is in a causal relationship:

- with the technical result of “reducing the resistance of the roll cushioning material to bending”, since the thickness of each layer is approximately two times less, therefore, when rolling separately, the force to bend the roll cushioning material with a smaller thickness requires less. Moreover, the total cushioning properties of two thin layers are not less than the cushioning properties of one thick layer;

with the technical result of “simplifying the provision of cylindricality and straightness of rolling” and the technical result of “simplifying the provision of the smallest possible diameter of the rolled roll”, since the reduction of the rolling forces creates the ability to direct the necessary effort and attention to ensuring the cylindricality of the first turn, straightness of rolling and the formation of the first turn of the minimum possible diameter, which determines the minimum possible diameter of the rolled roll to reduce the required storage space;

- with the technical result “improving the usability of a sports carpet by supplying it with technical means”, since the performance of a sports carpet of two layers is a technical tool that reduces bending resistance, which allows directing the released efforts to ensure cylindricality, straightness and the smallest possible diameter of the first turn ;

- with the total technical result “expansion of the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule”, as a result:

- reduces the time of rolling, moving and rolling sports carpet up to 6 ... 7 min, which is acceptable for use;

- makes the order of rolling, moving and rolling sports carpet accessible to the physical abilities of students.

The essential feature of “at least two unconnected” is in a causal connection with the technical result, since it is possible to make a sports carpet of three layers of roll-up cushioning material and this does not fundamentally change the technical results, moreover, as well as particular cases of execution allows you to get an additional technical result "expanding the functionality of the sports carpet", as it creates the opportunity to vary the shock-absorbing properties, for example, when for Aerobic exercise requires a single coat and bedspread.

Figure 1 ... figure 5 depicts the existing agreed upon procedure for athletes to roll a roll of shock-absorbing material, including PPE strips (in stages).

In Fig.19 shows a "Sports carpet" (option 2) in section.

In Fig.20 shows the location of the layers in mutually perpendicular directions.

Information confirming the possibility of implementing a utility model with obtaining the above technical results is as follows.

A sports carpet includes a roll of shock-absorbing material, for example, rolled PPE or PVV (secondary foaming polyurethane) mats glued to a common base, consisting of unconnected layer 14 and layer 15, a common blanket 2.

In this case, layer 14 and layer 15 can be made with the same or different damping properties determined by the density, for example, PES of 30 kg / m3 and 40 kg / m3, or PVV 100 kg / m3 and 140 kg / m3.

Moreover, layer 14 and layer 15 can be the same or different thicknesses, for example, 10 mm and 15 mm, which also determines the cushioning properties required for different sports.

In this case, layer 14 and layer 15 can be made of different materials, for example, from PES and PVV.

Roll up, move and roll out the sports carpet as follows.

Athletes disconnect the blanket 2, connected along the perimeter of the sports carpet with layer 14 or layer 15 of the roll of shock-absorbing material, using one of the known compounds, for example, Velcro contact tape (not shown in the figures), roll the blanket 2 into a roll and roll it to the wall of the sports hall to the storage place.

Then the athletes roll up the layer 14 of the roll cushioning material into a roll and fix it, for example, with a cord connection.

In this case, the bending force is required less, since the thickness of the layer 14 or layer 15 is less than the total thickness of the shock-absorbing roll material, which allows directing the released forces to ensure the cylindricality of the first turn, straightness of rolling, and also to ensure the smallest possible diameter of the first turn.

Then, the athletes roll up the layer 15 of the shock-absorbing material in a similar way and fix it from rolling, move it to the wall of the gym to the storage place, while the rolled-up layer 14 can be inside the rolled-up layer 15.

When the layer 14 and layer 15 are arranged in mutually perpendicular directions, the rolling and, accordingly, the rolling of the layers is carried out in different directions to different walls, which reduces the time when using only one layer for training, but at the same time increases the required storage space.

Preferred for use as layers of roll cushioning material are:

- rolled PES (chemically or physically crosslinked, see the INTEM website www.intem.mpi.ru), up to 15 mm thick and up to 40 kg / m ³ density.

- PPV mats with a thickness of up to 20 mm and a density of up to 160 kg / m ³ glued to a common base.

With an increase in the thickness and density of these materials, the bending resistance increases by so much that makes it difficult to use them for sports carpets using rolling without changing the design.

The efforts that must be made to roll two layers at the same time largely determine the weight of the sports carpet. It consists of the weight of a PVC blanket equal to 75 kg with a size of 10 m × 10 m and the weight of a roll of shock-absorbing material equal to 105 kg with a size of 0.035 m × 10 m × 10 m. The total weight of a sports carpet is approximately 180 kg. With a rolling friction coefficient of 0.3 for rolling a sports carpet, it is necessary to develop a total force of 0.3 × 180 kg = 54 kg, that is, each of the 20 athletes must develop a force of 2.7 kg, which is available to elementary school students.

In the manufacture of sports carpet made of PVC (secondary polyurethane foaming), the total weight will be approximately 550 kg, therefore, each of the 20 athletes must develop an effort of 8.25 kg, which is available to elementary school students.

The rolling of layer 14 and layer 15, as well as the laying of the bedspread 2, is carried out in the reverse order.

According to the object of the utility model “sports carpet” (option 3), a sports carpet is known that contains mats and coverings (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM company www .oktakem.ru, E-mail: market@oktakem.ru).

It is given as an analogue for its intended purpose, since it is the most common design of sports carpets used.

Its advantage is that the assembly, moving and disassembling according to physical abilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 30 minutes. due to the piece-wise alternate assembly and movement of the mats, the number of which in the sports carpet 10 m × 10 m is 50 pieces.

Tatami mats are known that contain mats with individual coatings and bases in the form of covers connected to mats (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM company www.oktakem.ru E-mail: market@oktakem.ru).

They are given as an analogue for their intended purpose, since they are the most common design of sports carpets.

The advantage is that the assembly, movement and disassembly of the tatami according to physical capabilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 25 ... 30 minutes due to piece-wise alternate assembly and displacement of mats, the number of which in the tatami 10 m × 10 m is 50 pieces.

A sports carpet is known that contains a synthetic blanket, a base connected with it, mats placed between them, bonded to the base, the base made of rubber-cord fabric, and metal plates fixed to the edge parts of opposite sides of the base (see A.S. SU No. 622472, class A63B 5/18, 1978).

The advantage is that physical movements are not required for its movements, since the movements are carried out by winches.

An advantage is also the minimum time required to prepare it for classes and moving to a storage place after classes, estimated at no more than 5 minutes.

The reason for a significant reduction in time is that the mats, the base and the bedspread are interconnected, forming a single whole, which allows the sports carpet to be wound on the drum as a rolled material, so the sports carpet is laid and moved in assembled form, as a result, time for piece-wise alternating is eliminated assembly and movement of mats.

The disadvantage is the movement of the sports carpet by sliding with support on the floor of the gym, as a result of which even a base made of rubber-cord fabric after several tens of movements will be destroyed by friction on the floor. Also, the paintwork of the floor and the layout of the playing fields will be destroyed.

The disadvantage is the need for a niche in the floor of the gym or the need for a drum with a diameter of approximately 500 mm and a length of more than 10 m.

As a result of these shortcomings, this sports carpet did not find practical application.

The closest device to the claimed utility model is “Covering on a gymnastic carpet”, containing strips of rolled PPE (polyethylene foam) measuring 2 m × 14 m and a thickness of 35 mm and 42 mm with carpets connected to them (see the website of ZAO AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru).

For transportation, PPE strips are rolled into rolls with an outer diameter of approximately 1 m, and at the place of use, they are rolled out and fastened with Velcro contact tape.

The advantage is that instead of mats, a roll-on PPE is used, which eliminates the piece-by-piece assembly and movement of mats, replacing them with assembly, moving and disassembling by rolling. This should significantly reduce the time required to prepare for classes and the release of the playground after classes.

The disadvantage is that for rolling each PPE strip into a roll, significant, depending on the width of the PPE strip, physical efforts of several at least two athletes are required, especially when forming the first and second turns, to stabilize the rolling process.

Significant efforts are needed to overcome the resistance of the PES strip to bending, while the greater the thickness of the PES strip, the greater the resistance to bending (the shock-absorbing properties of the PES, including the density in kg / m3 and the PES strip width, are assumed to be conditionally constant).

The second drawback is that the actions of athletes when rolling the PES strip, especially the first and second turns to stabilize the rolling process, must be carried out in a strictly coordinated manner.

This is necessary for the following reasons:

- for shaping the first and second turns by sequential and simultaneous impact on the PES band of two athletes at different points and directions in the conditions of overcoming the resistance of the PES band to bending;

- to ensure the cylindricality of the first turn, which determines the straightness of the further rolling of the PPE roll, including straightening and adjusting the non-linearity of rolling, arising due to the uneven bending of the first turn along the width of the PPE strip in the form of a wave-like end face of the PPE strip in the places of point application of hand efforts;

to ensure the formation of the smallest possible diameter of the first turn, which determines the diameter of the rolled roll and the required area for its storage;

- to ensure the fixation of the first turn and the constant pressing of the formed PPE coils to the straight-rolled straight part of the PPE strip lying on the floor to prevent it from springing under the influence of shock-absorbing properties with the formation of gaps between the coils during the whole rolling process. In this case, the springing occurs either by rolling, or, when the athletes counteract the rolling, sliding of the coils relative to and inside each other with an increase in diameters and the formation of gaps between the coils as a result.

The existing agreed procedure for the actions of athletes when rolling down the PES strip (in stages) is as follows:

- the first athlete, who is outside the PES strip, facing him, raises the edge of the PES strip with a change in direction along arrow A to a height of about 1 meter, while bending the PES strip by about 90 degrees;

- the second athlete, who is on the PES strip facing towards its edge, grabs the raised edge of the PES strip and bends it with a change in direction along arrow B by approximately 90 degrees, since he cannot bend the PES strip by a larger angle due to the slipping of the PES strip from hands under the action of springing forces and holds the PES strip in this position;

- the first athlete clicks on the PES strip with a change of direction in arrow A, while the second athlete presses on the edge of the PES strip with a change of direction in arrow B, presses the edge to the PPE strip, fixes it and checks the cylindricality of the first turn;

- both athletes make the previous step several times to correct the non-cylindricity of the first turn, which determines the further straightness of rolling, form the minimum possible diameter and the beginning of the second turn;

- the first and second athletes click on the PPE strip in the direction of arrows A and B, form a second loop and roll the PPE strip into a roll.

The presence of these disadvantages is clearly, but to a much lesser extent, manifested during the experimental rolling of a sheet of drawing paper "whatman", especially on the long side.

As a result of the total effect of the shortcomings, the time required to roll the PPE strip into a roll increases significantly, therefore, roll PPE is used only for the manufacture of stationary shock-absorbing coatings in specialized halls and such coatings are not intended for repeated rolling, moving and rolling within one day in universal sports halls, for example, in school gyms at general education physical education lessons.

The essence of the claimed utility model is as follows.

In the "Federal component of the state standard of general education", approved by order of the Ministry of Education of the Russian Federation on 05.03.2004, No. 1089, in the section "Training and Practical Equipment" in clause 5.24 it is indicated "Coating for wrestling carpet", and in clause 5.25 it is indicated "Mats wrestling ". Consequently, comprehensive schools in physical education lessons should conduct training for students in various types of martial arts.

But, even with the indicated mats and cover, schools are not able to include martial arts and other sports with the use of sports carpets in the curriculum, since the time of their assembly, movement and disassembly is more than 25 ... 30 minutes (more than 25% of the lesson’s training time) .

It is impossible to use coatings from rolled PES due to time constraints, and because of the complex, requiring considerable physical effort and actions in an agreed order process of rolling strips into rolls, a process difficult for schoolchildren, at least at primary and secondary schools.

Therefore, it is impossible to use well-known sports carpets, tatami, coverings from rolled PPE in the school schedule mode of physical education classes, which involves alternating classes on a sports carpet, for example, wrestling, and classes in the next lesson in game sports, for example, basketball, in one gym. Therefore, they have their schools either in stationary specialized halls with a room of more than 100 m2, or for demonstration purposes.

The problem the utility model aims to solve is to develop a sports carpet based on a roll of shock-absorbing material with the possibility of using it in the school schedule mode, for which it must meet the requirements:

- the time of rolling, moving and rolling the sports carpet should be no more than 6 ... 7 minutes;

- the agreed procedure for the athletes when rolling should be simplified by technical means, which will increase the convenience of using a sports carpet.

The technical results that will be achieved when these requirements are met, eliminate some of the above causes of deficiencies and are as follows:

- simplification of the provision of cylindricality and straightness of rolling;

simplification of providing the smallest possible diameter of a rolled roll;

- improving the usability of sports carpet by supplying it with technical means.

The total technical result is as follows:

- expansion of the arsenal of sports carpets for classes in universal sports halls, including physical education classes in secondary schools in the mode of the school lesson schedule.

The specified technical results in the implementation of the utility model are achieved by the fact that in a known sports carpet containing a roll of shock absorbing material and a cover, the feature is that at least one edge of the roll of shock absorbing material is provided with at least one row of stiffeners with the possibility of rolling, rolling and moving the sports carpet by rolling.

In addition, in addition, the other edge is provided with at least one row of stiffeners.

In addition, the stiffeners are made in the form of pairs of strips, while at least the lower strips are made of metal.

In addition, strips of pairs of stiffeners are connected by a cord connection.

In addition, the stiffeners are located in the outer grooves made in a roll of shock-absorbing material.

In addition, metal stiffeners are located in the internal grooves made in a roll of shock-absorbing material.

In addition, the rows of stiffeners are located at a distance of 50 ... 100 mm from the edges of the roll of shock-absorbing material.

In addition, at least one edge of the roll cushioning material is provided with three rows of stiffeners.

In addition, the distance between the rows of stiffeners is approximately equal to 1/3 of the circumference of the first turn.

In addition, the stiffeners are made in the form of segments 1 ... 2 m long.

In addition, stiffening ribs adjacent in width are interconnected by a flexible joint.

In addition, the weight of the metal strips is selected depending on the thickness of the roll of shock-absorbing material, its density and physical capabilities of athletes with the ability to perform metal bands of an additional function of cargo for shaping the first turn and an additional function of cargo to overcome the residual deformation of the edges of the deployed roll of shock-absorbing material.

In addition, the sports carpet is equipped with a mobile stop from rolling under the action of the shock-absorbing properties of the rolled roll.

The essential sign "... the edge ... is equipped with ... one row of stiffeners ..." is in a causal relationship:

with the technical result "simplification of the provision of cylindricality and straightness of rolling", since the stiffeners completely eliminate the uneven bending of the first turn along the width of the roll of shock-absorbing material in the form of a wave-like end face of the roll of shock-absorbing material at the points of the point of application of efforts of the hands of athletes. This is because the point forces of the hands are transformed by the stiffener into efforts along the line, which excludes the formation of a wave-like end face and ensures a constant rectilinear state of the end face. As a result, ensuring the cylindricality of the first turn and, therefore, the straightness of rolling is greatly simplified.

- with the technical result of “simplifying the provision of the smallest possible diameter of the rolled coil”, since the stiffening rib allows you to press the straight end face after bending the first turn in a straight line, which eliminates the wave-like editing and simplifies the shaping of the first turn of the smallest possible diameter.

- with the technical result “improving the usability of the sports carpet by supplying it with technical equipment”, since stiffeners are a technical tool that allows to exclude and / or simplify part of the steps in the agreed order of actions of athletes when rolling a roll of shock-absorbing material.

- with the total technical result “expansion of the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule”, as a result:

reduces the time of rolling, moving and rolling sports carpet up to 6 ... 7 minutes, which is acceptable for use;

- makes available the order of rolling, moving and rolling the sports carpet with the physical capabilities of students.

The essential feature "... the edge ... is equipped with ... one row of stiffeners ..." allows you to get additional technical results:

- "simplification of the formation of the first turn", as metal strips perform the function of goods bending the first turn;

- “overcoming the residual deformation of the edge of the roll cushioning material”, which is a consequence of rolling into a roll. In the roll-up cushioning material rolled out after that on the floor, the edges are raised above the floor under the influence of permanent deformation and it takes time or additional action on the edges to straighten them. This effect is like a load and has a metal strip of stiffeners. In this case, the edge bent at the end of rolling is subject to significantly less deformation due to the larger diameter into which it bends and the weight of the bedspread may be sufficient to straighten it.

- "local change in the resistance of the roll of shock-absorbing material to bending," since the bending will occur near the edge of the metal strip, especially when it is located in the outer or inner grooves due to a decrease in the thickness of the roll of shock-absorbing material along these lines. This simplifies the provision of cylindricality of the first turn.

In the particular case of the fulfillment of the essential sign “... at least one edge ... equipped ...”, it is possible to obtain an additional technical result “increasing the storage capacity of a sports carpet”, since supplying a roll of shock-absorbing material from two edges allows rolling and transporting a sports carpet to either of two opposite walls of the gym.

The essential feature “... equipped with at least one row ...” is in causal connection with the technical result, since even one row of stiffeners simplifies the provision of cylindricality, straightness of rolling and the smallest possible roll diameter.

Information confirming the possibility of implementing a utility model with obtaining the above technical results are as follows.

A sports carpet includes roll-up cushioning material 1, for example, roll-up PPE (polyethylene foam) or PVV mats (secondary foaming polyurethane) glued to a common base and a common blanket 2 made of PVC (polyvinyl chloride), stiffeners:

- in the form of pairs of strips, including a strip 16, for example, of flexible plastic or thick artificial leather, and a strip 17 of metal, while the strip 16 and strip 17 are connected by cord connection 18 and are located in the outer grooves 19 made in the roll of shock-absorbing material 1 a method of molding with a tool heated to the melting temperature of a roll of shock-absorbing material;

- in the form of strips 20 of metal, located and secured, for example, by adhesive bonding, in the internal grooves 21 made in the shock absorbing material 1 by molding using a tool heated to the melting temperature of the shock absorbing material 1, consisting of two interconnected, for example , heat sealing, layers;

- a flexible connection 22, for example, a cord connecting the stiffening ribs 16 and 17, or 20, adjacent in width, the mobile stop 23 from rolling the rolled roll under the action of the shock-absorbing properties.

Roll up, move and roll out the sports carpet as follows.

Athletes disconnect the cover 2, connected along the perimeter of the sports carpet with a shock-absorbing material 1, using one of the known compounds, for example, Velcro contact tape (not shown in the figures), roll the cover 2 into a roll and move it by rolling to the wall of the gym to the storage place .

Then the athletes roll the roll cushioning material 1 into a roll.

In this case, the stiffeners completely eliminate the uneven bending of the first turn in width in the form of a wave-like end face of the roll shock-absorbing material 1, which simplifies the provision of cylindricality of the first turn, straightness of rolling and the smallest possible diameter of the first turn by technical means.

Special cases of execution are provided for:

- outer grooves 19 in the roll cushioning material 1 so as not to increase the thickness of the sports carpet;

- internal grooves 21 in the roll cushioning material 1 so that the metal strips are covered with shock absorbers;

- rows of stiffeners at a distance of 50 ... 100 mm from the edges of the roll of shock-absorbing material so that when the first turn is formed, the end face of the roll of shock-absorbing material 1

in contact with the roll cushioning material 1, since in this case the end slippage is less;

- three rows of stiffeners from one edge in order to enhance the technical result;

- connection of 22 adjacent stiffening ribs in order to connect the strips into a single whole when using a rolled PPE;

- a mobile emphasis 23 from rolling in order to prevent spontaneous rolling of the roll.

Preferred for use are materials:

- rolled PES (chemically or physically crosslinked, see the INTEM website www.intem.mpi.ru), up to 30 mm thick and up to 40 kg / m ³ density.

- PPV mats with a thickness of up to 40 mm and a density of up to 160 kg / m ³ glued to a common base.

With an increase in the thickness and density of these materials, the bending resistance increases by so much that makes it difficult to use them for sports carpets using rolling

The effort that you need to make to roll, for the most part, determines the weight of the sports carpet. It consists of the weight of a PVC blanket equal to 75 kg with a size of 10 m × 10 m and the weight of a roll of shock-absorbing material equal to 105 kg with a size of 0.035 m × 10 m × 10 m. The total weight of a sports carpet is approximately 180 kg. With a rolling friction coefficient of 0.3 for rolling a sports carpet, it is necessary to develop a total force of 0.3 × 180 kg = 54 kg, that is, each of the 20 athletes must develop a force of 2.7 kg, which is available to elementary school students.

In the manufacture of a sports carpet made of PVC (secondary polyurethane foaming), the total weight will be approximately 550 kg, therefore, each of the 20 athletes must develop an effort of 8.25 kg, which is available to elementary school students.

Rolling the roll and laying the coverlet 2 is carried out in the reverse order.

According to the object of the utility model “sports carpet” (option 4), a sports carpet is known that contains mats and coverings (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM company www .oktakem.ru. E-mail: market@oktakem.ru).

It is given as an analogue for its intended purpose, since it is the most common design of sports carpets used.

Its advantage is that the assembly, moving and disassembling according to physical abilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 30 minutes. due to the piece-wise alternate assembly and movement of the mats, the number of which in the sports carpet 10 m × 10 m is 50 pieces.

Tatami mats are known that contain mats with individual coatings and bases in the form of covers connected with mats (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM www.oktakem.ru , E-mail: market@oktakem.ru).

They are given as an analogue for their intended purpose, since they are the most common design of sports carpets.

The advantage is that the assembly, movement and disassembly of the tatami according to physical capabilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 25 ... 30 minutes due to piece-wise alternate assembly and displacement of mats, the number of which in the tatami 10 m × 10 m is 50 pieces.

A sports carpet is known that contains a synthetic blanket, a base connected with it, mats placed between them, bonded to the base, the base made of rubber-cord fabric, and metal plates fixed to the edge parts of opposite sides of the base (see A.S. SU No. 622472, class A63B 5/18, 1978).

The advantage is that physical movements are not required for its movements, since the movements are carried out by winches.

An advantage is also the minimum time required to prepare it for classes and moving to a storage place after classes, estimated at no more than 5 minutes.

The reason for a significant reduction in time is that the mats, the base and the bedspread are interconnected, forming a single whole, which allows the sports carpet to be wound on the drum as a rolled material, so the sports carpet is laid and moved in assembled form, as a result, time for piece-wise alternating is eliminated assembly and movement of mats.

The disadvantage is the movement of the sports carpet by sliding with support on the floor of the gym, as a result of which even a base made of rubber-cord fabric after several tens of movements will be destroyed by friction on the floor. Also, the paintwork of the floor and the layout of the playing fields will be destroyed.

The disadvantage is the need for a niche in the floor of the gym or the need for a drum with a diameter of approximately 500 mm and a length of more than 10 m.

As a result of these shortcomings, this sports carpet did not find practical application.

The closest device to the claimed utility model is “Covering on a gymnastic carpet”, containing strips of rolled PPE (polyethylene foam) measuring 2 m × 14 m and a thickness of 35 mm and 42 mm with carpets connected to them (see the website of ZAO AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru).

For transportation, PPE strips are rolled into rolls with an outer diameter of approximately 1 m, and rolled out at the place of operation.

The advantage is that instead of mats, a roll-on PPE is used, which eliminates the piece-by-piece assembly and movement of mats, replacing them with assembly, moving and disassembling by rolling. This should significantly reduce the time required to prepare for classes and the release of the playground after classes.

The disadvantage is that for rolling each PPE strip into a roll, significant, depending on the width of the PPE strip, physical efforts of several at least two athletes are required, especially when forming the first and second turns, to stabilize the rolling process.

Significant efforts are needed to overcome the resistance of the PES strip to bending, while the greater the thickness of the PES strip, the greater the resistance to bending (the shock-absorbing properties of the PES, including the density in kg / m3 and the PES strip width, are assumed to be conditionally constant).

The second drawback is that the actions of athletes when rolling the PES strip, especially the first and second turns to stabilize the rolling process, must be carried out in a strictly coordinated manner.

This is necessary for the following reasons:

- for shaping the first and second turns by sequential and simultaneous impact on the PES band of two athletes at different points and directions in the conditions of overcoming the resistance of the PES band to bending;

- to ensure the cylindricality of the first turn, which determines the straightness of the further rolling of the PPE roll, including straightening and adjusting the non-linearity of rolling, arising due to the uneven bending of the first turn along the width of the PPE strip in the form of a wave-like end face of the PPE strip in the places of point application of hand efforts;

to ensure the formation of the smallest possible diameter of the first turn, which determines the diameter of the rolled roll and the required area for its storage;

- to ensure the fixation of the first turn and the constant pressing of the formed PPE coils to the straight-rolled straight part of the PPE strip lying on the floor to prevent it from springing under the influence of shock-absorbing properties with the formation of gaps between the coils during the whole rolling process. In this case, the springing occurs either by rolling, or, when the athletes counteract the rolling, sliding of the coils relative to and inside each other with an increase in diameters and the formation of gaps between the coils as a result.

The existing agreed procedure for the actions of athletes when rolling down the PES strip (in stages) is as follows:

- the first athlete, who is outside the PES strip, facing him, raises the edge of the PES strip with a change in direction along arrow A to a height of about 1 meter, while bending the PES strip by about 90 degrees;

- the second athlete, who is on the PES strip facing towards its edge, grabs the raised edge of the PES strip and bends it with a change in direction along arrow B by approximately 90 degrees, since he cannot bend the PES strip by a larger angle due to the slipping of the PES strip from hands under the action of springing forces and holds the PES strip in this position;

- the first athlete clicks on the PES strip with a change of direction in arrow A, while the second athlete presses on the edge of the PES strip with a change of direction in arrow B, presses the edge to the PPE strip, fixes it and checks the cylindricality of the first turn;

- both athletes make the previous step several times to correct the non-cylindricity of the first turn, which determines the further straightness of rolling, form the minimum possible diameter and the beginning of the second turn;

- the first and second athletes click on the PPE strip in the direction of arrows A and B, form a second loop and roll the PPE strip into a roll.

The presence of these disadvantages is clearly, but to a much lesser extent, manifested during the experimental rolling of a sheet of drawing paper "whatman", especially on the long side.

As a result of the total effect of the shortcomings, the time required to roll the PPE strip into a roll increases significantly, therefore, roll PPE is used only for the manufacture of stationary shock-absorbing coatings in specialized halls and such coatings are not intended for repeated rolling, moving and rolling within one day in universal sports halls, for example, in school gyms at general education physical education lessons.

The essence of the claimed utility model is as follows. In the "Federal component of the state standard of general education", approved by order of the Ministry of Education of the Russian Federation on 05.03.2004, No. 1089, in the section "Training and Practical Equipment" in clause 5.24 it is indicated "Coating for wrestling carpet", and in clause 5.25 it is indicated "Mats wrestling ". Consequently, comprehensive schools in physical education lessons should conduct training for students in various types of martial arts.

But, even with the indicated mats and cover, schools are not able to include martial arts and other sports with the use of sports carpets in the curriculum, since the time of their assembly, movement and disassembly is more than 25 ... 30 minutes (more than 25% of the lesson’s training time) .

It is impossible to use coatings from rolled PES due to time constraints, and because of the complex, requiring considerable physical effort and actions in an agreed order process of rolling strips into rolls, a process difficult for schoolchildren, at least at primary and secondary schools.

Therefore, it is impossible to use well-known sports carpets, tatami, coverings from rolled PPE in the school schedule mode of physical education classes, which involves alternating classes on a sports carpet, for example, wrestling, and classes in the next lesson in game sports, for example, basketball, in one gym. Therefore, they have their schools either in stationary specialized halls with a room of more than 100 m2, or for demonstration purposes.

The problem the utility model aims to solve is to develop a sports carpet based on a roll of shock-absorbing material with the possibility of using it in the school schedule mode, for which it must meet the requirements:

- the time of rolling, moving and rolling the sports carpet should be no more than 6 ... 7 minutes;

- the agreed procedure for the athletes when rolling should be simplified by technical means, which will increase the convenience of using a sports carpet.

The technical results that will be achieved when these requirements are met, eliminate some of the above causes of deficiencies and are as follows:

- simplification of the provision of cylindricality and straightness of rolling;

- simplification of providing the smallest possible diameter of the rolled roll;

- improving the usability of sports carpet by supplying it with technical means.

The total technical result is as follows:

- expansion of the arsenal of sports carpets for classes in universal sports halls, including physical education classes in secondary schools in the mode of the school lesson schedule.

The specified technical results during the implementation of the invention are achieved by the fact that in the well-known sports carpet containing a roll of shock absorbing material and a cover, the peculiarity is that the roll of shock absorbing material is equipped with a Velcro contact tape with the ability to fix the coils when rolling, rolling and moving the sports carpet by rolling .

In addition, the upper surface of the roll cushioning material is provided with a “hinged” part of the Velcro tape, and the lower surface is equipped with a “hooked” part of the Velcro tape.

In addition, the "hinged" parts are located across the rolling direction, and the "hook" parts are located along the rolling direction.

In addition, the "loop" and "hook" parts are made in the form of segments and are located at intervals between the segments.

In addition, the gaps between the “hook” segments are selected depending on the gaps between the “loop” segments, depending on the thickness of the roll cushioning material, depending on the diameter of the first turn of the roll cushioning material with the possibility of contact between the “loop” and “hook” segments when rolling down.

In addition, the "loop" segments are located in recesses made in a roll of shock-absorbing material.

In addition, the first "loop" segments are located from the initial edge of the roll of shock-absorbing material at a distance equal to the circumference of the first turn, and the first "hook" segments are located on the edge of the roll of shock-absorbing material with rotation on the end and upper surface of the roll of shock-absorbing material.

In addition, the last "loop" segments are located on the end edge of the roll of shock-absorbing material in an increased quantity and in two rows, and the last "hook" segments are made of an increased length.

In addition, two rows of “hinged” segments are located on two additional strips of rolled shock-absorbing material, while the additional strips of rolled shock-absorbed material are inextricably connected to each other and the rolled shock-absorbed material with an additional short cover.

The essential feature "equipped with a Velcro contact tape with the ability to fix the turns when rolling, rolling and moving the sports carpet by rolling" is in a causal relationship:

- with the technical result “simplification of ensuring the cylindricality and straightness of rolling”, as it fixes the cylindricality of the first turn formed by the athletes and prevents the change in cylindricality during further rolling, which ensures straightness of rolling.

- with the technical result “simplifying the provision of the smallest possible diameter of the rolled coil”, since it fixes the minimum possible diameter of the first turn formed by the athletes, and also prevents the rolled coils from springing up by sliding the coils relative to and inside each other with an increase in the diameter of the rolled coil.

- the technical result “improving the usability of the sports carpet by supplying it with technical means”, since the Velcro contact tape is a technical tool that performs or simplifies some of the actions of athletes when rolling, rolling and moving the sports carpet by rolling, including ensuring cylindricality, straightness of rolling, springing with an increase in the diameter of the rolled roll, etc., which increases the usability.

- with the total technical result “expansion of the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule”, as a result:

- reduces the time of rolling, moving and rolling the sports carpet up to 6 ... 7 minutes, which is acceptable for use.

- makes available the order of rolling, moving and rolling the physical capabilities of students.

In Fig. 1 ... Fig. 5 shows the existing agreed upon procedure for athletes to roll a roll of shock-absorbing material, including a PPE strip (in stages)

On Fig shows a "sports carpet" (option 4), side view.

On Fig the same, top view.

On Fig shows the location of the "loop" segment of the contact tape "Velcro" in the recess in the roll of shock-absorbing material and a blanket.

The sports carpet includes roll-up cushioning material 1, roll-up PPE (foam-resistant) or PVV mats (secondary foaming polyurethane) glued to a common base, general blanket 2 made of PVC (polyvinyl chloride), segments of the “hinged” part 24 of the Velcro tape, segments of the “hook” "Parts 25 of the Velcro tape, recesses 26, made in a roll of shock-absorbing material by forming a tool heated to the melting temperature of a roll of shock-absorbing material, additional strips 27 of a roll of shock-absorbing material, additional tively short cover 28.

Roll up, move and roll out the sports carpet as follows.

Athletes disconnect the blanket 2, connected along the perimeter of the sports carpet with shock absorbing material 1, using one of the known compounds, for example, Velcro contact tape (not shown in the figures), roll the blanket 2 into a roll and move it by rolling to the wall of the gym to the storage place .

Then the athletes roll the roll cushioning material 1 into a roll.

In this case, the formed first turn is fixed by connecting the “hook” and “loop” segments of the Velcro contact tape, which eliminates the change in the formed cylindricality of the first turn and the diameter of the first turn in the process of further rolling, which ensures straightness of rolling.

In addition, in the process of rolling, the “hook” 25 and “loop” 24 segments are joined along the length of the roll of shock-absorbing material 1, which eliminates the springing of the formed coils by sliding relative to each other with an increase in the diameter of the rolled coil.

Special cases of execution include:

- supplying the upper surface of the roll cushioning material 1 with a “looped” part 24 of the Velcro tape, since the “looped” part 24 is soft and will not protrude significantly under the cover 2, for this, recesses 26 are also made in the roll cushioning material 1.

- the implementation of the "loop" 24 and the "hook" 25 parts of the segments to save materials.

- the location of the "loop" 24 segments on the end edge of the roll of shock-absorbing material 1 in an increased, for example, 2 times, quantity and in two rows to provide more reliable fixation of the rolled roll from rolling.

- the location of the two rows of "looped" 24 segments on two additional strips 27 of roll-up cushioning material 1 and the permanent connection of the additional bands 27 and roll-up cushioning material 1 with an additional short blanket 28 to prevent a sharp springing of the edge of the roll cushioning material 1 when the "loop" 24 and " hook "25 parts for rolling. In this case, the rolled roll should lie on the end edge of the roll of shock-absorbing material 1.

Preferred for use are materials:

- rolled PES (chemically or physically crosslinked, see the INTEM website www.intem.mpi.ru), up to 30 mm thick and up to 40 kg / m ³ density.

- PPV mats with a thickness of up to 40 mm and a density of up to 160 kg / m ³ glued to a common base.

With an increase in the thickness and density of these materials, the bending resistance increases by so much that makes it difficult to use them for sports carpets using rolling

The effort that you need to make to roll, for the most part, determines the weight of the sports carpet. It consists of the weight of a PVC blanket equal to 75 kg with a size of 10 m × 10 m and the weight of a roll of shock-absorbing material equal to 105 kg with a size of 0.035 m × 10 m × 10 m. The total weight of a sports carpet is approximately 180 kg. With a rolling friction coefficient of 0.3 for rolling a sports carpet, it is necessary to develop a total force of 0.3 × 180 kg = 54 kg, that is, each of the 20 athletes must develop a force of 2.7 kg, which is available to elementary school students.

In the manufacture of sports carpet made of PVC (secondary polyurethane foaming), the total weight will be approximately 550 kg, therefore, each of the 20 athletes must develop an effort of 8.25 kg, which is available to elementary school students.

Rolling the roll and laying the coverlet 2 is carried out in the reverse order.

According to the object of the utility model “sports carpet” (option 5), a sports carpet is known that contains mats and coverings (see the website of CJSC AKROSPORT www.acrosport.ru, E-mail: admin@acrosport.ru and the website of OKTAKEM company www .oktakem.ru. E-mail: market@oktakem.ru).

It is given as an analogue for its intended purpose, since it is the most common design of sports carpets used.

Its advantage is that the assembly, moving and disassembling according to physical abilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 30 minutes. due to the piece-wise alternate assembly and movement of the mats, the number of which in the sports carpet 10 m × 10 m is 50 pieces.

Tatami mats are known that contain mats with individual coatings and bases in the form of covers connected to the mats (see the website of CJSC AKROSPORT www.acrosport.ru. E-mail: admin@acrosport.ru and the website of OKTAKEM company www.oktakem.ru E-mail: market@oktakem.ru).

They are given as an analogue for their intended purpose, since they are the most common design of sports carpets.

The advantage is that the assembly, movement and disassembly of the tatami according to physical capabilities are available to students.

The disadvantage is the significant assembly, displacement and disassembly times of more than 25 ... 30 minutes due to piece-wise alternate assembly and displacement of mats, the number of which in the tatami 10 m × 10 m is 50 pieces.

A sports carpet is known that contains a synthetic blanket, a base connected with it, mats placed between them, bonded to the base, the base made of rubber-cord fabric, and metal plates fixed to the edge parts of opposite sides of the base (see A.S. SU No. 622472, class A63B 5/18, 1978).

The advantage is that physical movements are not required for its movements, since the movements are carried out by winches.

An advantage is also the minimum time required to prepare it for classes and moving to a storage place after classes, estimated at no more than 5 minutes.

The reason for a significant reduction in time is that the mats, the base and the bedspread are interconnected, forming a single whole, which allows the sports carpet to be wound on the drum as a rolled material, so the sports carpet is laid and moved in assembled form, as a result, time for piece-wise alternating is eliminated assembly and movement of mats.

The disadvantage is the movement of the sports carpet by sliding with support on the floor of the gym, as a result of which even a base made of rubber-cord fabric after several tens of movements will be destroyed by friction on the floor. Also, the paintwork of the floor and the layout of the playing fields will be destroyed.

The disadvantage is the need for a niche in the floor of the gym or the need for a drum with a diameter of approximately 500 mm and a length of more than 10 m.

As a result of these shortcomings, this sports carpet did not find practical application.

The closest device to the claimed utility model is “Covering on a gymnastic carpet”, containing strips of rolled PPE (polyethylene foam) measuring 2 m × 14 m and a thickness of 35 mm and 42 mm with carpets connected to them (see the website of ZAO AKROSPORT www.acrosport.rn, E-mail: admin@acrosport.ru).

For transportation, PPE strips are rolled into rolls with an outer diameter of approximately 1 m, and at the place of use, they are rolled out and fastened with Velcro contact tape.

The advantage is that instead of mats, a roll-on PPE is used, which eliminates the piece-by-piece assembly and movement of mats, replacing them with assembly, moving and disassembling by rolling. This should significantly reduce the time required to prepare for classes and the release of the playground after classes.

The disadvantage is that for rolling each PPE strip into a roll, significant, depending on the width of the PPE strip, physical efforts of several at least two athletes are required, especially when forming the first and second turns, to stabilize the rolling process.

Significant efforts are needed to overcome the resistance of the PES strip to bending, while the greater the thickness of the PES strip, the greater the resistance to bending (the shock-absorbing properties of the PES, including the density in kg / m3 and the PES strip width, are assumed to be conditionally constant).

The second drawback is that the actions of athletes when rolling the PES strip, especially the first and second turns to stabilize the rolling process, must be carried out in a strictly coordinated manner.

This is necessary for the following reasons:

- for shaping the first and second turns by sequential and simultaneous impact on the PES band of two athletes at different points and directions in the conditions of overcoming the resistance of the PES band to bending;

- to ensure the cylindricality of the first turn, which determines the straightness of the further rolling of the PPE roll, including straightening and adjusting the non-linearity of rolling, arising due to the uneven bending of the first turn along the width of the PPE strip in the form of a wave-like end face of the PPE strip in the places of point application of hand efforts;

- to ensure the formation of the smallest possible diameter of the first turn, which determines the diameter of the rolled roll and the required area for its storage;

- to ensure the fixation of the first turn and the constant pressing of the formed PPE coils to the straight-rolled straight part of the PPE strip lying on the floor to prevent it from springing under the influence of shock-absorbing properties with the formation of gaps between the coils during the whole rolling process. In this case, the springing occurs either by rolling, or, when the athletes counteract the rolling, sliding of the coils relative to and inside each other with an increase in diameters and the formation of gaps between the coils as a result.

The existing agreed procedure for the actions of athletes when rolling down the PES strip (in stages) is as follows:

- the first athlete, who is outside the PES strip, facing him, raises the edge of the PES strip with a change in direction along arrow A to a height of about 1 meter, while bending the PES strip by about 90 degrees;

- the second athlete, who is on the PES strip facing towards its edge, grabs the raised edge of the PES strip and bends it with a change in direction along arrow B by approximately 90 degrees, since he cannot bend the PES strip by a larger angle due to the slipping of the PES strip from hands under the action of springing forces and holds the PES strip in this position;

- the first athlete clicks on the PES strip with a change of direction in arrow A, while the second athlete presses on the edge of the PES strip with a change of direction in arrow B, presses the edge to the PPE strip, fixes it and checks the cylindricality of the first turn;

- both athletes make the previous step several times to correct the non-cylindricity of the first turn, which determines the further straightness of rolling, form the minimum possible diameter and the beginning of the second turn;

- the first and second athletes click on the PPE strip in the direction of arrows A and B, form a second loop and roll the PPE strip into a roll.

The presence of these disadvantages is clearly, but to a much lesser extent, manifested during the experimental rolling of a sheet of drawing paper "whatman", especially on the long side.

As a result of the total effect of the shortcomings, the time required to roll the PPE strip into a roll increases significantly, therefore, roll PPE is used only for the manufacture of stationary shock-absorbing coatings in specialized halls and such coatings are not intended for repeated rolling, moving and rolling within one day in universal sports halls, for example, in school gyms at general education physical education lessons.

The essence of the claimed utility model is as follows.

Consequently, comprehensive schools in physical education lessons should conduct training for students in various types of martial arts.

But, even with the indicated mats and cover, schools are not able to include martial arts and other sports with the use of sports carpets in the curriculum, since the time of their assembly, movement and disassembly is more than 25 ... 30 minutes (more than 25% of the lesson’s training time) .

It is impossible to use coatings from rolled PES due to time constraints, and because of the complex, requiring considerable physical effort and actions in an agreed order process of rolling strips into rolls, a process difficult for schoolchildren, at least at primary and secondary schools.

Therefore, they have their schools either in stationary specialized halls with a room of more than 100 m2, or for demonstration purposes.

The problem the utility model aims to solve is to develop a sports carpet based on a roll of shock-absorbing material with the possibility of using it in the school schedule mode, for which it must meet the requirements:

- the time of rolling, moving and rolling the sports carpet should be no more than 6 ... 7 minutes;

The technical result that will be achieved when these requirements are met eliminates some of the causes of the above disadvantages and consists in the following:

- improving the usability of sports carpet by supplying it with technical means.

The total technical result is as follows:

expanding the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule.

The specified technical results in the implementation of the utility model are achieved by the fact that in the well-known sports carpet containing a roll of shock absorbing material and a cover, the feature is that the roll of shock absorbing material is equipped with devices for manual rolling, rolling and rolling of the sports carpet.

In addition, the devices are made in the form of tapes located between the shock-absorbing roll material and the floor of the gym.

In addition, the tapes are connected to the edges of the roll cushioning material.

In addition, the length of the tapes made more than the length of the roll of shock-absorbing material.

In addition, the devices are made in the form of tapes passed through grooves made in a roll of shock-absorbing material with an alternate arrangement of tapes on the upper and lower surfaces of the roll of shock-absorbing material, while the tapes are connected to the edges of the roll of shock-absorbing material.

In addition, the distance between the grooves is made equal to 200 ... 400 mm.

In addition, the device is made in the form of segments of tapes connected to the lower surface of the roll of shock-absorbing material.

In addition, segments of tapes are located along or across the rolling direction.

In addition, the device is made in the form of grooves in a roll of shock-absorbing material.

In addition, the grooves are made across the rolling direction with a length of 100 ... 120 mm and in increments of 200 ... 400 mm.

In addition, the grooves are made to a depth of part of the thickness of the roll cushioning material.

The essential feature "equipped with devices for manual rolling, rolling and moving the sports carpet by rolling" is in a causal relationship:

- with the technical result “improving the usability of a sports carpet by supplying it with technical means”, since supplying a roll of shock-absorbing material with technical means — devices for manually rolling, rolling and moving a sports carpet by rolling — increases usability, including:

- tapes located between the shock-absorbing roll material and the floor of the sports hall allow athletes with one hand movement while pulling the tapes in a horizontal plane to roll and roll the shock-absorbing material into a roll and press the rolled coils to a straight non-rolled part to prevent springing, which allows other athletes to provide other rolling parameters.

- tapes passed through grooves made in a roll of shock-absorbing material, segments of tapes connected to the bottom surface of the roll of shock-absorbing material and grooves made in the roll of shock-absorbing material, ensure reliable hand grip of the smooth surface of the roll of shock-absorbing material.

- with the total technical result “expansion of the arsenal of sports carpets for classes in universal gyms, including physical education classes in secondary schools in the mode of the school lesson schedule”, as the result:

- reduces the time of rolling, moving and rolling the sports carpet up to 6 ... 7 minutes, which is acceptable for use.

- makes available the order of rolling, moving and rolling the physical capabilities of students.

The essential feature “equipped with devices for manual rolling ...” is expressed in a generalized form, since various forms of its implementation are possible.

Figure 1 ... figure 5 shows the existing agreed upon procedure for athletes when rolling a roll of shock-absorbing material, including the PES strip (in stages).

A sports carpet includes roll-up cushioning material 1, for example, PPE (polyethylene foam) or PVV mats (secondary foaming polyurethane) glued to a common base, general blanket 2 made of PVC (polyvinyl chloride), a device for manual rolling, rolling and rolling movements:

- made in the form of tapes 29 located between the roll of cushioning material 1 and the floor of the gym, and connected to the edges of the roll of cushioning material 1;

- made in the form of segments of tapes 32, connected, for example, by an adhesive connection, with a roll of shock-absorbing material 1;

- made in the form of grooves 33 in a roll cushioning material 1.

Roll up, move and roll out the sports carpet as follows.

Then the athletes roll the roll cushioning material 1 into a roll.

While the tape 29, located between the roll of shock-absorbing material 1 and the floor of the sports hall, forms the first turn, while pressing it to the surface of the roll of shock-absorbing material 1, preventing the strands from springing up, during the whole rolling process. Since the tapes 29 are connected to the edges of the roll cushioning material 1, when rolling the tapes 29 are located between the turns and are used to roll the roll in a similar way.

Also, the tapes 30, passed through the grooves 31, the segments of the tapes 32 connected to the lower surface of the roll cushioning material 1, the grooves 33 increase the usability of the sports carpet by ensuring reliable hand grip on the smooth surface of the roll cushioning material 1.

Preferred for use are materials:

- rolled PES (chemically or physically crosslinked, see the INTEM website www.intem.mpi.ru), up to 30 mm thick and up to 40 kg / m ³ density.

- PPV mats with a thickness of up to 40 mm and a density of up to 160 kg / m ³ glued to a common base.
