Description

Connection system for movable sports floors

technical field

The invention relates to a connection system for movable sports floors according to the preamble of claim 1 . Such connection systems are used in particular in halls where sports or other leisure events have to be fitted with a suitable floor covering which can be removed again if necessary.

Background technique

Hitherto in such raised sports floors, which consist of several hundred individual floor elements with a size of about 100 x 100 cm, tenon joints or other shapes in the form of grooves and tenon or tenon engaging with recesses have generally been used Locking tenon joints, as disclosed in DE3343601C2, DE3523357C2, these individual floor elements are also used in revolving floors, where the individual floor elements consist of thick plywood, fiberboard or blockboard with a parquet layer or another A floor covering with a final total thickness of approximately 30-35mm.

With fully form-fitting dowel joints, the function is greatly influenced by the prevailing climatic conditions, since the floor elements are manufactured with a relative wood humidity of 8% and a fit tolerance of 0.3 mm, thus allowing them to perform under different climatic conditions. Changes occur during storage or long-term transport in containers. During container transport, the condensate and condensate moisture affect the wood according to the season and duration. After that, it can only be laid with difficulty or with the help of trimming. If the individual floor elements are then exposed to the standard climatic conditions of the wood industry for a longer period of time, the trimming again has a negative effect on the accuracy of fit.

Furthermore, EP0698162 discloses a connection system for floors in which metal connection clips are used. The clips are flexible and allow the rotatable plate to snap into the connection system. However, the mechanical stability of this connection system is limited, so that it is not suitable for sports floors.

Contents of the invention

It is therefore the object of the present invention to provide a connection system for a movable sports floor in which the individual panels are connected to one another in as positive and stable a manner as possible.

This object is solved by a connection system with the features of claim 1 .

According to the invention, the receiving profile on a plate has a groove, wherein structures are provided on the groove, said structures enabling the clamping of the receiving profile to the adjacent plate during the deflection of the plate with the clamping profile Profiles are joined together. Due to the fact that the profiles join together when the newly laid panels are deflected, two adjacent panels can achieve a form-locking contact by means of their longitudinal edges. The stability is increased by the receiving profile and the clamping profile, since they are fixed to the plate.

According to a preferred embodiment of the invention, a projection is formed on the receiving profile, which projection is clamped from behind by a part of the clamping profile to connect the two plates. In this case, the receiving profile can be substantially C-shaped, on the upper side of which a downwardly directed projection is provided. If a plate with clamping profile is attached obliquely to a horizontal plate with receiving profile and then the plate with clamping profile is turned downwards, a part of the clamping profile engages the receiving profile from behind bump on that side of the .

For a particularly stable connection of the two panels, the receiving profile is made of metal and is seated on a longitudinal edge of a panel, for example made of wood. The metal profile avoids climatic and especially humidity influences, which have a negative effect on the shape of the panels and make high-precision laying impossible.

Preferably, the clamping profile has a web inserted into the plate, to which a mushroom-head-shaped projection is attached. The web enables a stable connection between the plate and the clamping profile, and for a particularly stable connection a screw connection can be provided between the plate and the connecting piece. The clamping profile can have an upwardly pointing section, wherein a receptacle for a downwardly pointing projection on the receiving profile is provided between this section and the longitudinal edge of the plate. This makes it possible to achieve a form-locking locking of two adjacent panels, in which case the own weight of the panels first has to be overcome in order to release the locking again. Preferably, the clamping profile in the locked state not only abuts against the projection of the upper side of the receiving profile, but also rests against the lower side of the receiving profile. For the introduction of the clamping profile with mushroom-shaped projections, an introduction ramp is preferably provided on the underside of the receiving profile. Since the ideal point of rotation is formed on the upper edge of the panel during the deflection of the new panel to be laid, the panel can achieve a form-locking fit through this shape of the clamping profile and the receiving profile. Rely, here the clamping profile abuts not only on the upper edge of the receiving profile, but also on its lower edge.

According to a further embodiment of the invention, the receiving profile has a base section which is flush with the base of the plate. The lower edge of the receiving profile forms an extension of the panel to a certain extent, so that the panel can be laid particularly precisely, since the receiving profile, which is mostly made of metal, rests flat on the ground without causing slight warping of, for example, wood.

If a base section is additionally provided on the receiving profile, which partially engages the panel from below, support can be provided on this base section when the panel is loaded in the region of the receiving profile. Even with high mechanical loads, such material stresses can be avoided because the plate is supported on the one hand on the upper section of the receiving profile and on the other hand on its bottom section, so that it can be carried out via the receiving profile. force transfer.

In order to achieve a particularly stable mechanical connection of the receiving profile and the clamping profile, they are made of metal, preferably aluminum, and are each connected to a plate by means of screw connections. In such a case, a plurality of clamping profiles can also be arranged distributed over the longitudinal edges of the plate.

According to another embodiment of the invention, the board is designed as a multi-layer wood board, the underside of which is provided with a plurality of grooves spaced apart from one another to increase the elasticity of the board. An important aspect in sports flooring is to achieve a certain degree of force resolution, especially in order to protect the players' joints, so the panels need to have a certain degree of elasticity. However, particularly good reflexes must be achieved with relatively low loads, for example in order to achieve ball reflexes in ball games. This enlargement and elastic effect can be achieved while maintaining the reflection of the ball if the groove accounts for about 1/5-1/2 of the total thickness in such a plank.

In order to be able to lay the slabs directly on hard floors, the underside of the slabs can be fixedly connected to a cushion made of elastic material.

Detailed ways

The connection system shown in FIGS. 1-5 comprises a plurality of panels 1 which can be connected to adjacent panels 2 . The plates 1 and 2 are each rectangular and identical in construction and have a receiving profile 8 on a first longitudinal edge and a clamping profile 4 on an opposite second longitudinal edge. Boards 1 and 2 are designed as multilayer wooden boards glued together and can have a protective layer of parquet or other material.

The receiving profile 8 has a groove 3 formed between the upper side 5 and the lower side 6 of the C-shaped receiving profile 8 . The upper edge 5 is provided with a downwardly directed projection 9 which is flush with the longitudinal edge of the plate 1 . A section 16 of the plate 1 is arranged above the upper side 5 so that the receiving profile 8 is invisible. The lower edge 6 of the receiving profile 8 is provided at its outer end with an introduction ramp 10 which is approximately flush with the longitudinal edge 17 of the panel 1 . The receiving profile 8 is connected to the plate 1 between the sides 5 and 6 by several horizontal screws 25 , the heads of which are embedded in the receiving profile 8 . The slab 1 is laid on the ground 15 .

Fastened to the second plate 2 is a clamping profile 4 which is inserted into the plate 2 with a bridge 11 . The webs 11 are fastened in the plate 2 by screws 26 at several points on the bottom of the plate 2 . Formed integrally with the web 11 is a mushroom head-shaped projection 12 which has a rounded surface facing the receiving profile 8 . Formed on the upper section 13 of the projection 12 is a receptacle 14 which is arranged between a longitudinal edge 18 of the plate 2 and the section 13 . The projection 9 of the receiving profile 8 can engage in this receiving portion 14 in order to lock the plates 1 and 2 .

To lay the second slab 2 , the slab 2 is first installed at an angle into the slab 1 lying on the ground 15 , as shown in FIG. 2 . Then the plate 2 is lowered slightly and the clamping profile 4 with the mushroom head 12 is inserted into the groove 3 of the receiving profile 8 . At the end of the swiveling movement of the plate 2 , it is only substantially turned about the axis 7 formed by the connection of the upper edges of the plates 1 and 2 . When the plate 2 is further lowered, the projections 13 of the clamping profile 4 rest against the projections 9 of the upper side 5 of the receiving profile 8 , while in the lower region the mushroom-head-shaped projections 12 are on the insertion ramp 10 of the lower side 6 Swipe up. In the laid state of FIG. 4 , the clamping profile 4 with the mushroom-head-shaped projections 12 rests on the projection 9 on the upper side 5 on the one hand and on the lower side 6 of the receiving profile 8 on the other hand. This enables a particularly stable and form-fitting fastening on the longitudinal edges of the plates 1 and 2 .

To increase the elasticity of the panels 1 and 2 made of wood, grooves 30 are milled at intervals of approximately 10-20 cm, extending approximately over 1/3 of the total thickness of the panels. The width of the groove is about 3-6 times of the plate thickness. The grooves have a width of about 3-6 mm and are indicated by dashed line 30 in FIG. 4 .

FIG. 5 shows a connection system according to the invention with a plurality of plates 1 and 2 in the mounted state. The boards 1 are placed in a row and the other boards 2 are held offset by the locking system described above. A frame 20 is mounted around the laid panels 1 and 2, which frame 20 can likewise be fixed on the longitudinal and transverse edges according to the above-mentioned locking system. Edge elements are provided on the longitudinal and transverse sides to lock the frame.

Other forms of fastening can be used on the end faces of the plates 1 and 2 , such as snap-in connections, clamping elements or groove-and-mortise connections.

FIG. 6 shows a second embodiment in which the receiving profile 8' is substantially modified. Other components are still denoted by the same reference numerals and correspond to the above-mentioned embodiments. The receiving profile 8 ′ has an upper edge 5 on which a downwardly directed projection 9 is formed, which serves as a stop for the upper section 13 of the clamping profile 4 on the plate 2 . In addition, a lower edge 6 is provided on the receiving profile 8 ′, which is flush with the underside of the panel 1 on the ground side and is therefore laid directly together with the underside on the foundation. The rear side of the side 6 of the receiving profile 8 ′ is formed with a base section 80 which protrudes oppositely between the upper side 5 and the lower side 6 via a connecting region 82 . A part 81 of the plate 1 is supported on the bottom section 80 . Since the panel 1 is supported on the one hand on the upper side 5 and on the other hand on the bottom section 80 , material loads are avoided in the loading of the panel 1 in the region of the receiving profile 8 ′.

FIG. 7 shows an embodiment similar to that of FIG. 6 , the same reference symbols being used for the same components. Each of the plates 1 and 2 is provided with a plate-shaped cushion layer 90 made of an elastic material, and the cushion layer 90 is fixedly connected to the plate 1 or 2 respectively. The cushion layer 90 can consist of a foam material with optimum damping properties, preferably polyurethane foam. For placing the underlayment 90 on each board 1 or 2, a non-woven fabric layer 91 is connected to the underlayment 90, where the non-woven fabric layer 91 is adhered to each board 1 or 2 using an adhesive such as glue. 2 on. To improve the adhesion of the underlayment 90, layers of cork or other suitable materials can also be inserted instead of non-woven layers.

Each underlayment 90 is approximately the size of the board 1 or 2 on which it is located. In such cases, the underlayments 90 can also be designed with a slight gap 92 between them, which does not adversely affect the workability of the floor.

A connecting element thus formed from the board 1 or 2 and the underlayment 90 can be laid on a hard floor without having to spread a further elastic underlayment on the ground. This eliminates the pre-work process of laying the underlayment in the floor installation. Furthermore, the underlayment 90 has no adverse effect on the mounting of the panels 1 and 2 because the underlayment 90 has only a slight own weight.

In the exemplary embodiment described, the receiving profile 8 or 8' and the clamping profile 4 consist of aluminum. Other metallic and non-metallic materials such as plastics may also be used. The fixing of the clamping profile 4 and the receiving profile 8 or 8' can also be replaced by other fasteners instead of the screw connection.

The embodiments of FIGS. 4 and 6 can also be combined with one another in that instead of the receiving profile 8', the longitudinal edges of the plate 1 are arranged in a U-shape. This brings about the advantage that the distribution of the mechanical load on the plate 1 can be improved by the structure of the web 81 protruding rearward from the connecting region 82, in which case the lower edge 6 is invisible on the bottom surface, This is because the base section of the plate 1 engages the lower edge from below.
