Description

  The present invention relates to an improved system for carrying objects such as backpacks or bags.

  When carrying an object such as a backpack or bag, the level of comfort depends not only on the static load due to the weight of the object but also on the dynamic load. For example, when a person is walking or running, the vertical movement and acceleration of the object may greatly increase the dynamic load compared to the static load. In general, the faster a person moves, the greater the dynamic load for a given static load. This problem is therefore particularly important in athletic applications.

  The prior art provides several possible solutions to this problem. EP 2371232 relates to an insert for a transport strap for transporting an object which essentially comprises an elastic section and a restriction section, the length of the restriction section being adjustable. JP 2005-304827 relates to a school bag intended to be transported stably on the back. DE 29910127 relates to a backpack comprising two carrying straps, each carrying strap comprising an elastic section and means for limiting the extension of the strap under load. Japanese Patent No. 5713160 relates to a school bag having two shoulder belts, the shoulder belts including an inner belt and an outer belt. U.S. Pat. No. 6,070,776 relates to a backpack and the length of the shoulder strap automatically adjusts when the wearer twists the torso. The shoulder straps are connected at the lower end to form one continuous strap. This strap passes under the bottom panel of the backpack and is received in the channel. Due to the low friction properties, the continuous strap can slide freely in the channel. US Patent Application Publication No. 2017/0265630 discloses a pack body, two shoulder straps extended from the pack body to allow the wearer to wear the pack body on the wearer's back, and the pack body. The present invention relates to a backpack including a suspension structure including a resilient unit provided between a pack body and a shoulder strap to absorb a large force. U.S. Pat. No. 5,954,253 relates to a load support system including a flexible frame unit attached to a shoulder support structure and a hip belt assembly. EP-A-2324731 includes a carrier made of at least one flexible carrier material, and a front part to be placed on the front of the wearer and the wear when the system is worn by the wearer The present invention relates to a load carrying system for a wearer that includes a rear portion to be placed on a person's back. French Patent Application No. 2974981 relates to a device for transporting luggage, including a carrier base.

  However, during the wearer's dynamic movement, the object will generally move not only vertically but also horizontally. The more the object moves horizontally from the center of mass of the wearer's body, the heavier the object feels. For example, in general, the farther the center of mass of the object is from the center of mass of the wearer's body, the torque applied by the object's center of mass about the axis of rotation that can be the point of contact of the object with the wearer's back is Will increase. It is a drawback of the prior art that this problem has not been addressed. This problem is not limited to the dynamic case, but also applies under static conditions.

European Patent Application Publication No. 2371232 JP 2005-304827 A German utility model No. 29910127 specification Japanese Patent No. 5713160 US Pat. No. 6,070,776 US Patent Application Publication No. 2017/0265630 US Pat. No. 5,954,253 European Patent Application Publication No. 2324731 French Patent Application Publication No. 2974981

  Accordingly, the problem underlying the present invention is to provide a transport system for an object that provides better wearing comfort than existing transport systems, especially under dynamic conditions.

  This object is achieved according to the teachings of the independent claims, in particular by a transport system for transporting an object, the transport system being (a) an essentially elastic part and (b) an essentially elastic part. An essentially elastic portion, wherein the portion is attached to the object at a first position disposed on the object; and (c) a restricted configuration, wherein the length of the restricted configuration is that of the essentially elastic portion. Limiting the maximum extension, (d) the limiting configuration is attached to at least one second position on the object 20 different from the first position.

  In this context, an “essentially elastic part” can return to an unloaded length after applying a force of at least 200 N, preferably up to 500 N, apart from small deviations. The length of the “essentially elastic part” increases by at least 1%, preferably by 5%, under the application of a force of 100N. The increase in length under load or force is called “stretching”.

  An advantage of the transport system according to the invention is that the essentially elastic part draws the object towards the wearer's body. In this context, the wearer is the person who carries the object by the carrying system. For example, the wearer can carry the object on the back. In this case, the essentially elastic part will draw the object towards the wearer's back. An important insight by the inventors is that the essentially elastic portion is attached to the object at a first position disposed on the object, while the limiting configuration is at least in the object different from the first position. It is attached to one second position.

  For example, the constraining arrangement may be placed under an essentially elastic portion in the object, i.e. at least one second position is placed under the first position in the object. “Under” means in this context “disposed” in the normal orientation of the transport system and the object when the transport system is worn by the user to transport the object. Alternatively, the restrictive configuration can be placed over an essentially elastic portion in the object. “On” in this context means “placed higher” in the normal orientation of the transport system and the object when the transport system is worn by the user to transport the object.

  Either arrangement allows the object to be drawn into a more vertical arrangement, reducing the torque applied by the object around the axis of rotation that may be the point of contact between the object and the wearer.

  Note that the restrictive configuration and / or the elastic portion can each be attached to the object at more than one location. In particular, in addition to the at least one second position, the restricting configuration may be attached to the object at a further position that may be different from the first position or may coincide with the first position. In any case, the restrictive configuration is attached to the object at at least one position different from the first position (“at least one second position”).

  Therefore, the transport system advantageously reduces the forces resulting from the vertical and horizontal movement of the object during the wearer's movement. The limiting configuration serves to stabilize the transport system by limiting the maximum extension of the essentially elastic portion.

  The restriction configuration can include a restriction strap and a guide portion, the guide portion being attached to the object in the second position, and the restriction strap being slidably attached to the guide portion.

  Therefore, the restraining strap can be moved to fit the wearer's anatomical requirements and to further weaken the forces due to vertical and horizontal movement of the object during dynamic movement. . The guide portion ensures sufficient stability by limiting the movement of the limiting strap along the guide portion.

  The guide portion can include a guide tape. The tape can include any type of fabric, such as woven, non-woven, or knitted fabric. Alternatively or additionally, the guide tape can consist of an elastomer such as polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester. This makes it possible to make the guide part comfortable, low friction and low weight, in particular compared to eg a metal structure.

  The limiting strap can be slidably attached to the guide portion by a first essentially loop-shaped tape and / or a first ring. The first “essentially loop-shaped tape” may or may not be closed loop. The first ring can have many shapes including a circular shape, a rectangular shape, an elliptical shape, or variations thereof. The first ring may or may not be closed. The ring may be made of a hard material such as metal or hard plastic, or may be made of a soft material such as soft plastic. The first essentially loop-shaped tape or first ring can be made of any type of fabric, such as woven fabric, non-woven fabric, knitted fabric or the like. It is only important that the movement of the limiting strap is limited to be along the guide portion. Alternatively or additionally, the essentially loop-shaped tape or ring may consist of an elastomer, such as polyethylene, polypropylene, chlorosulfonated polyethylene, polyester. This allows the first loop-shaped tape or first ring to be comfortable, low friction and low weight.

  The limiting configuration includes a guide portion and a first essentially loop-shaped tape and / or first ring, but may not include a limiting strap. This enables a particularly lightweight structure.

  The limiting configuration can be less elastic than the elastic portion in nature. In this context, a small amount of elasticity is required to stretch the inherently elastic part by the same amount, for example 5%, to stretch the restricted configuration by a given amount, for example 5%. This means that a force greater than the required force is required. This difference can be achieved by different elastic moduli (also known as Young's modulus) and / or by different thicknesses. Therefore, the limiting configuration can effectively limit the maximum extension of the essentially elastic portion. The elasticity of the limiting configuration can be determined at least by the elasticity of the limiting strap, the elasticity of the guide portion, and / or the elasticity of the first essentially loop-shaped tape or first ring.

  The at least one second position can be vertically separated from the first position by a first vertical distance. By separating by a first vertical distance, the tilt of the object in a static situation and the range of possible tilts during dynamic movement allow for a more ergonomic fit and better shock absorption. Can be designed to.

  The first vertical distance can be at least 2 cm, preferably at least 5 cm, more preferably at least 8 cm. The greater the first vertical distance, the more stable the orientation of the object and the smaller the range of possible inclinations during dynamic movement.

  The first position disposed on the object may be located at a second vertical distance of at least 2 cm, preferably at least 5 cm, more preferably at least 10 cm below the top of the object. The greater the distance between the top of the object and the first position, the higher the center of mass of the object relative to the center of mass of the wearer's body. The inventors have found that it is easier for the wearer to hold the weight of the object when the center of mass of the object is placed as high as possible relative to the center of mass of the wearer's body. This is especially true for objects worn on the back of the body, such as backpacks.

  The limiting configuration can include a cushioning element. The cushioning element serves two purposes. First, the cushioning element provides comfort to the wearer due to a cushioning effect. Secondly, because of the thickness of the cushioning element, the cushioning element can serve as the axis of rotation. In combination with an essentially elastic portion, this creates a lever for pulling the object into a more vertical position during use, thereby providing more ergonomic wearability. The cushioning element can act as a shoulder pad. If the restraining strap is slidably attached to the guide portion, this configuration further allows the cushioning element to better fit the shoulder shape and therefore distribute the load more evenly than conventional shoulder pads. .

  The essentially elastic portion can include at least a first layer and a second layer. In this way, the nature of the inherently elastic part can be designed more diversely.

  The first layer can include an elastic mesh. The elastic mesh is breathable and lightweight and can be used to provide a highly elastic first layer.

  The first layer has a first elastic modulus, the second layer has a second elastic modulus, and the first elastic modulus may not be the same as the second elastic modulus. This advantageously expands the range of elastic properties with which an essentially elastic part can be designed. For example, the first elastic modulus can be greater than the second elastic modulus, or alternatively, the second elastic modulus can be greater than the first elastic modulus. A low modulus means that the material is more elastic, i.e. stretches more under a given force.

  The first layer can have a different length than the second layer. This further advantageously expands the range of elastic properties with which an essentially elastic part can be designed. For example, the first layer can be longer than the second layer. Here, the length is determined along the longitudinal direction of the first layer. For example, if the first elastic modulus is greater than the second elastic modulus, the essentially elastic portion initially stretches fairly easily under the application of force, and then the second layer becomes the first When stretched to the same length as the layer, a greater force is required to further stretch the essentially elastic portion. In this way, it is possible to increase the strength of the transport system in a heavy usage situation.

  The limiting configuration can have a third elastic modulus, and the third elastic modulus can be lower than the first elastic modulus and the second elastic modulus. For example, if the limiting configuration has the same thickness as the first layer and the second layer, the limiting configuration can be less elastic than the first layer and the second layer. In this way, the limiting configuration can effectively limit the maximum stretch of the inherently elastic portion, but allows a relatively thin thickness and thereby a relatively low weight of the limiting configuration.

  The limiting strap and / or guide portion can include a woven fabric. The woven fabric advantageously has good strength and high breathability. Alternatively, the limiting strap and / or guide portion can include other types of fabric, such as nonwoven or knitted fabric.

  The essentially elastic portion can be attached to the restriction configuration at a third position located in the restriction configuration. In this way, the stability of the transport system is advantageously improved. “Attached” in this context can mean “directly attached”.

  The transport system may further include a retaining element attached to the restriction configuration at a fourth position disposed in the restriction configuration and a fifth position disposed in the restriction configuration, wherein the essentially elastic portion comprises Located between the holding element and the restricting configuration in the 4th and 5th positions, the essentially elastic part is not attached to the restricting configuration in the 4th and / or 5th position. If the essentially elastic part is not attached to the restrictive configuration in the fourth position and / or the fifth position, the flexibility of the transport system is advantageously improved. However, there is even better stability if the essentially elastic part is arranged between the retaining element and the restricting configuration in the fourth and fifth positions.

  Lateral movement of the essentially elastic portion relative to the restricting configuration may be prevented or restricted in the fourth position and / or the fifth position. This improves the lateral stability of the transport system.

  The retaining element can include a second essentially loop-shaped tape or a second ring. The second essentially loop-shaped tape or second ring has the same properties as the first essentially loop-shaped tape or first ring, respectively, as described herein. Therefore, the second loop-shaped tape or second ring is comfortable and low in weight.

  The retaining element can be made of an elastomer, such as polyethylene, polypropylene, chlorosulfonated polyethylene, or polyester. Therefore, the holding element is particularly durable and low weight.

  The essentially elastic portion and the restrictive configuration can be part of the carrying strap. The advantageous properties of the inherently elastic part and the restrictive configuration are very well utilized for the carrying strap.

  The object can be a backpack or bag, or part thereof. The invention further relates to a backpack or bag comprising at least one transport system according to the invention as described herein. The backpack or bag is generally worn on the shoulder and may be worn on the back. Therefore, the advantageous properties of the transport system according to the present invention are particularly beneficial for backpacks or bags.

FIG. 2 shows an exemplary backpack and delivery system according to the present invention. FIG. 6 illustrates the advantages of an exemplary backpack and delivery system according to the present invention. 3B is a side view (FIG. 3A) and a front view (FIG. 3B) of an exemplary delivery system according to the present invention. 3B is a side view (FIG. 3A) and a front view (FIG. 3B) of an exemplary delivery system according to the present invention. FIG. 6 shows an alternative embodiment of a backpack and transport system according to the present invention. FIG. 6 shows an alternative embodiment of a backpack and transport system according to the present invention.

  In the following, only some possible embodiments of the present invention will be described in detail. It should be understood that these exemplary embodiments may be modified in many ways and may be combined with each other whenever they are not in conflict, and certain functions may be omitted as long as they are not considered important. Although the present invention is primarily described with reference to a transport system 10 for a backpack 20, it should be understood that the transport system 10 according to the present invention can be used to transport any object.

  FIG. 1 shows an exemplary transport system 10 for transporting an object 20, the exemplary transport system 10 being an essentially elastic portion 11 and a first disposed on the object 20. An essentially elastic portion 11 that is attached to the object 20 at position 17 and a restrictive configuration, wherein the length of the restrictive configuration limits the maximum extension of the essentially elastic portion 11 and the restrictive configuration is first. Position 17 (best shown in FIG. 3A) and a restrictive configuration that is attached to a second position on the object 20 that is different. In this example, the limiting configuration (its limiting strap 12 can be seen in FIG. 1) is placed under the essentially elastic portion 11 of the object.

  The transport system 10 advantageously reduces the forces resulting from the vertical and horizontal movement of the object during the wearer's movement. The limiting configuration serves to stabilize the transport system 10 by limiting the maximum extension of the essentially elastic portion 11.

  The limiting configuration is less elastic than the essentially elastic portion 11. In this example, a force of 120 N is required to stretch the limiting configuration by 5% in length, but only a force of 20 N is required to stretch the essentially elastic portion 11 by the same percentage of 5%. In this example, this difference is achieved by a difference in elastic modulus, also known as Young's modulus, and a difference in thickness. The elastic modulus of the limiting configuration is twice as large as that of the essentially elastic part 11. Moreover, the limiting configuration is 3 times thick, which means that the cross-sectional area is essentially 3 times larger than the elastic part 11.

  In this example, the backpack 20 includes a main body 21, a left transport system 10, and a right transport system 10. The left carrying system 10 is part of the left shoulder strap 26b, and the right carrying system 10 is part of the right shoulder strap 26a. The left shoulder strap 26b further includes a male connecting element 15 and the right shoulder strap 26a further includes a female connecting element 16, whereby the left carrying system and the right carrying system are connected to each other so that the wearer's back The stability of the backpack 20 can be improved. Each shoulder strap 26a, 26b further includes a buckle 14 to adjust the overall length of the shoulder strap 26a, 26b.

  The first position 17 arranged on the object is arranged at a second vertical distance 23 of 5 cm below the top 22 of the object. The limiting configuration includes a cushioning element. The limiting strap 12 further includes a woven fabric. The essentially elastic portion 11 is attached to the restricted configuration at a third position 31 arranged in the restricted configuration. The transport system 10 further includes a holding element 13 which will be described in more detail below with reference to FIG. 3B.

  FIG. 2 shows the advantageous technical effects of the transport system 10 according to the invention. The advantage of the transport system 10 according to the invention is that the essentially elastic part 11 draws the object towards the wearer's body 25 and provides an impact absorbing effect. In this example, the object is the backpack 20. In this context, the wearer is the person who carries the object by the carrying system 10. For example, the wearer can carry the backpack 20 on the back. In this case, the essentially elastic part 11 will draw the backpack 20 towards the wearer's back.

  For example, consider a situation where a wearer steps or jumps quickly. This causes a sudden acceleration of the backpack 20 both horizontally and vertically. Reference numeral 27a indicates the position of the backpack containing the transport system 10 according to the invention during acceleration. The backpack 20 is inclined away from the wearer's body 25. When the backpack 20 is at the position 27a, the center of mass of the backpack 20 is located at the position 24a. The essentially elastic part of the transport system 10 makes it possible to move the backpack and therefore advantageously absorbs shocks. Reference numeral 27b indicates the position of the backpack 20 immediately after acceleration. The backpack 20 is quickly pulled back to a more vertical arrangement, and the center of mass 24b of the backpack 20 is located closer to the body 25 than the center of mass 24a during acceleration, thereby providing contact between the object and the wearer. The torque applied by the backpack 20 around the axis of rotation that can be a point is reduced.

  FIG. 3A shows an exemplary transport system 10 for transporting an object 20 (shown on the left), which is an essentially elastic portion 11 and is disposed on the object 20. An essentially elastic portion 11 attached to the object 20 at a first position 17 and a limiting configuration, the length of the limiting configuration limiting the maximum extension of the essentially elastic portion 11 and limiting The configuration includes a limiting configuration that is attached to a second position 34 on the object 20 that is different from the first position 17. Note that the restriction configuration is further attached to the object 20 at the first position 17. What is important, however, is that the limiting configuration is further attached to the object 20 at a second position 34 that is different from the first position 17. In this example, the limiting arrangement is arranged under the essentially elastic part 11 in the object. The essentially elastic portion 11 and the limiting configuration are part of the shoulder strap 26.

  The restriction configuration includes a restriction strap 12 and a guide portion 18 that is attached to the object 20 at a second position 34 and the restriction strap 12 is slidably attached to the guide portion 18.

  The guide portion 18 includes a guide tape. The guide tape includes a woven fabric made of an elastomer, in this example, polypropylene. The limiting strap 12 is slidably attached to the guide portion 18 by a first essentially loop-shaped tape 19, which is a woven fabric made of an elastomer, in this example polypropylene. Further included.

  The essentially elastic portion 11 includes at least a first layer 11a and a second layer 11b. The first layer 11a includes an elastic mesh. The first layer 11a has a first elastic modulus, the second layer 11b has a second elastic modulus, and the first elastic modulus is not the same as the second elastic modulus. In this example, the first elastic modulus is larger than the second elastic modulus. The first layer 11a has a length different from that of the second layer 11b. In this example, the first layer 11a is longer than the second layer 11b. The limiting configuration has a third elastic modulus, which is lower than the first elastic modulus and the second elastic modulus.

  FIG. 3B shows a front view of the transport system 10 for transporting an object shown in the side view of FIG. 3A.

  The essentially elastic portion 11 is attached to the restricted configuration at a third position 31 arranged in the restricted configuration.

  The transport system 10 further includes a retaining element 13 attached to the restriction configuration at a fourth position 32 arranged in the restriction configuration and a fifth position 33 arranged in the restriction configuration, wherein the essentially elastic portion 11 is In the fourth position 32 and the fifth position 33 between the retaining element 13 and the restricting configuration, the essentially elastic part 11 being restricted in the fourth position 32 and / or the fifth position 33. Not attached to the configuration. The lateral movement of the essentially elastic part 11 with respect to the restricting configuration is restricted at the fourth position 32 and / or the fifth position 33. This improves the lateral stability of the transport system 10.

  The restriction configuration includes a restriction strap 12 and a guide portion 18 that is attached to the object 20 at a second position 34 and the restriction strap 12 is slidably attached to the guide portion 18.

  The guide portion 18 includes a guide tape. The guide tape includes a woven fabric made of an elastomer, in this example, polypropylene. The limiting strap 12 is slidably attached to the guide portion 18 by a first essentially loop-shaped tape 19, which is a woven fabric made of an elastomer, in this example polypropylene. Further included.

  The retaining element 13 comprises a second essentially loop-shaped tape. In this example, the holding element 13 consists of chlorosulfonated polyethylene.

  4A and 4B show an exemplary embodiment in which the limiting configuration is disposed on the essentially elastic portion 11 of the object 20. The object 20 is a rucksack and is shown only as an outline. The transport system 10 for transporting the object 20 is an essentially elastic part 11, which is attached to the object 20 at a first position 17 located on the object 20. And the length of the limiting configuration limits the maximum extension of the essentially elastic portion 11, and the limiting configuration is attached to the second position 34 a in the object 20 different from the first position 17. And a restricted configuration. Note that the restriction configuration is further attached to the object 20 at another second position 34b that is also different from the first position 17. Both the second position 34 a and the second position 34 b are disposed on the first position 17. However, it is possible that only one of the second position 34 a and the second position 34 b is disposed on the first position 17. In this example, the second position 34a is vertically spaced from the first position 17 by a first vertical distance of 5 cm. In this example, the elastic portion 11 is pleated.

  Limiting configurations that limit the maximum extension of the essentially elastic portion 11 include the guide portion 18, the first essentially loop-shaped tape 19, the first ring 41a, and the second ring 41b. The essentially elastic portion 11 and the limiting configuration are part of the shoulder strap 26.

  The guide portion 18 is attached to the object 20 at the second position 34a and the second position 34b. The guide portion 18 includes a guide tape.
