The invention relates to a connection system quadrangular in form of plates, panels, having two long edges and two short edges, and the connection system has a connection profiles, which are located on the edges, and are located on opposite sides of the connecting profiles so suited to each other that a homogeneous panel can be connected to each other.

For example, international application WO 94/26999 known connection system panels for flooring, in which the connecting profile in the United state form a geometric circuit in a direction that extends perpendicular to the plane of installation, which must meet the panel and form a geometric circuit in a direction that lies in the plane of stacking and extends perpendicular to the coupled edges. The connecting profile according to international application WO 54/269999 include in this groove and tongue which is inserted into the groove when the connecting profiles are connected to each other. When connecting the tongue and groove surface of a stud comes in contact with the adjacent surface of the groove, so that spike could rely on the groove.

From U.S. patent US 6,808,777 also known connection system panels, and connecting profiles have a protrusion from the upper side, is inclined to the plane at the gasket, and the notch with similarly inclined to the plane of installation of the lower side. In the United state of connecting profiles of the lower side of the recess adjacent to the upper side of the ledge, and the inclination of the lower side and the upper side forms a positive locking connection profiles in a direction that lies in the plane of stacking and extends transversely to the connecting profiles.

The upper side of the ledge and the lower fitting grooves respectively provided with increasing friction layer, so that hampered relative movement of the protrusion and the recess. Due to increasing friction layers with a high coefficient of friction PHmay be, thus reinforcing the connection of the connecting profiles. Due to the inclination of the upper side of the ledge and the bottom side of the recess relative to the plane of installation, subject to the connection panel to connect connection profiles that can be moved on each other not in the flat position. On the contrary, the slope of one of the panels necessary to insert the connecting profiles at each other. The panels, which have the appropriate connection profile as on the long edges and short edges, installation can be difficult, so as to connect the panel with the already placed another panel should be rotated around its long CROs is key, and around its short edges.

Hence the object of the invention is to develop a system of panels, which panels are securely joined to each other and which makes possible a simple installation.

Underlying the invention the task is solved by a combination of characteristics according to paragraph 1 of the claims. The preferred embodiments can be derived from the dependent claims.

According to paragraph 1, proposed in accordance with the invention, the connection system is characterized by the fact that in the direction of the DEinserting, in which the moving surface and the mating surface relative to each other when connecting the connecting profile, which increases the friction layer has a coefficient of friction RNthat is less than the coefficient of friction RH. In the preferred embodiment increases the friction layer has a higher coefficient of friction RHin the opposite direction to the direction of insertion.

Additionally or alternatively, an increased coefficient of friction RHit may happen in the direction orthogonal to the direction of insertion DE.

When the connecting profile for connecting panels are inserted into each other, and at least one surface moves along a conjugate of p the surface, according to the invention due to the increasing friction layer for separating the connecting profiles, i.e. for movement toward or perpendicular to the direction of insertion DEmust be accompanied by a greater force than when the connection of the connecting profile and the connection of the connecting profiles occurs with movement in the direction of the DEinserting. The direction of the DEthe insertion may be due to the linear moving, moving with rotation or a combination of both.

In extreme cases, short and long edges may be of the same length. Then it would be appropriate panel would be square.

In the preferred embodiment, the layer is formed by a layer obtained by flocking. The layer obtained by flocking, may include the base layer and the short fiber, which sealed end fixed in the main layer, and the free end looking from the base layer. The short fibers may be inclined to the direction of the DEinserting. If the surface is equipped with such obtained using the flocking layer, coming in the direction of the DEinserting on the mating surface, the short fibers due to its inclination to create less resistance to the relative movement of the surface and the mating surface in comparison with the movement of Sopra the military surface against the direction of insertion, as in this case, the short fibers are directed against this movement.

Short fibers may have along its entire length a constant slope. Short fibers can be the beginning of inclination in the region of the ends embedded in the core layer. Inclined position relatively short fibers of the base layer is in the manufacture of a layer of flocking, i.e. already before the connection of the connecting profiles of the short fibers have a slope.

Additionally, the length of the short fibers may be chosen so that they will be more than a gap between a surface provided with a layer obtained by flocking, and counterface, which is formed when the connecting profiles are connected to each other. When connecting surface and the adjacent surface of the short fiber is bent obliquely downward or formed in the direction of the DEinserting in addition to their original inclination in order to interact with the counterface with power tilt.

The connection system may be designed so that the connection profiles on the long edges of the connecting profiles correspond to the connecting profiles on the short edges. Thus, in principle, could have been, the connection profile on the short edge to connect with the connecting profile is long to is omce, consequently when laying the panels could produce the figure in the tree.

Alternatively, the connecting profiles on the long edges can be formed as the first connecting profiles and short edges as the second connecting profile, and in this case, the first connecting profiles differ from the second connecting profiles. Mainly the first connection profiles the long edges together in a positive locking in the direction D1 and positive locking in the direction D2, while the second connecting profiles short edges form a geometric circuit in only one direction or in the direction D1 or in the direction D2. This is crucial, you may simplify the laying of the panels, as the panels together along their short edges, they should only be vdvinut'sâ one another or may overlap one another.

The connecting profiles, for example, the first and second connecting profiles of the above-described exemplary embodiment may have a groove on the first side groove wall and the second side wall of the groove, and a thorn from the lower side and upper side, and the thorn is in the groove when the connecting profiles are connected, resulting in the formed positive locking in the direction D1 perpendicular to square Scotti styling. Increasing the friction layer can be provided on the upper side, lower side or the upper side and the lower side of the cleat. Alternatively or additionally increase the friction layer can be provided on the first side wall of the groove and/or the second side wall of the groove. It is also possible that the entire spike, i.e. the lower side, the upper side and the end side of a thorn covered increases the friction layer. It makes sense for groove, and in this case, along with the first side wall of the groove and the second groove wall of the bottom part of the groove likewise has increase the friction layer.

In the preferred embodiment, the connecting profiles have the locking element and the groove for fixing, which receives the locking element in the United state of connecting profiles, which formed as a result of the geometric circuit in the direction D2 orthogonal to the United edges. The stopper element and the groove for fixing may be under tension, so that the connecting profiles form an interference fit. Moreover, at least in the direction between the locking element and the groove for fixing may be a gap, so that between the connecting profiles may be movable landing. In addition, the connection of the connecting profiles can also be carried out in view of the transition of the landing. Possible compression between the coupling profiles or increase can only be explained by the presence of increasing the friction layer.

The locking element and the groove for fixing can be performed in such a way that the connecting profile can be inserted into each other in an inclined towards each other position, and at least one of the connecting profile has an angle of inclination to the plane of installation. By making the connecting profiles to the inclined position so that they lie in the same plane, the locking element and the groove for fixing are engaged without the application of mechanical force.

Connection profiles can be made so that, despite increasing the friction layer, they can be moved to each other along the edges of the panels when the panels are tilted to each other.

The locking element and the groove for fixing can be performed so that the connecting profiles can hang on each other mainly in the flat position, both of the connecting profile lie in the plane of installation. An example for this kind of execution of the stopper element and the groove for fixing is latched or locking connection, which when nadhani connecting profiles leads to deformation of the connecting element profile, and deformation after fixation, reduced or full the STU runs.

Increasing the friction layer can be provided on the first side wall and/or the second side wall of the groove for fixing. The wall of the retainer may also be provided to increase the friction layer.

The lower side of a thorn in the cross section can be made convex, while the first side wall of the groove, which, when United connective profiles communicates with the lower side of the stud may be made concave. Due to the curvature of the lower part of the spike and the first side wall of the groove may be formed swivel around an axis of rotation parallel to the edges of the United connective profiles. Due to the curvature formed in the rear neckline, so that the connecting profiles form a geometric snapping in two directions D1, D2.

In a preferred embodiment, the connecting profiles, mainly short edges, include the first element in the form of a hook and the second element in the form of a hook, which respectively have the jumper hook and the end part of the hook and the retainer hook connects the end part of the hook with the panel, and in the United state of connection profiles end part hooks captured mutually in the direction D2. The advantage is designed in such a way of connecting profiles is that, in order to connect the connector the s profiles the panel can simply impose on each other. Increasing the friction layer can be provided on the inner side of the end portion of the hook on the outer side of the end portion of the hook, on the end side end portion of the hook on the side wall lintel hook and/or the trailing wall of the hook.

Mainly provided by the groove for dust or Luggage for dust, which, when viewed in the direction of the DEinsertion is located behind the surface, equipped with increasing friction layer. Thus, in the groove for dust or chamber for the dust can be collected short fibers, which when connecting the connecting profiles showered with basic layer is a layer obtained by flocking.

Can be applied to all embodiments, if increasing the friction layer in all directions is equal to the value of the frictional resistance or approximately equal to the value of the frictional resistance. This can complicate the installation, however, so can be also achieved good results.

The invention is explained in more detail with the embodiments shown in the drawing, where:

Figure 1 - Two panels;

Figure 2 is a First exemplary embodiment for connecting profiles;

Figure 3 - Connecting the profiles in figure 2 on an enlarged scale;

Figure 4 is a Second example of Khujand is the implementation for connecting profiles;

Figure 5 is a Third exemplary embodiment for connecting profiles;

Figure 6 - Schematic of the method of installation of the panels;

Figure 7 is Another way of laying the panels.

On figure 1 in a perspective view shows two laminate panels 1, 2, and design are the same. Laminate panel 1 has an upper side 3 and the lower side 4. Located on the perimeter edge includes two long edges 5, 51and two short edges 6, 61. In connection with the same design panel 2 is provided respectively in the same positions of the symbol.

Panels 1, 2 to the edges 5, 516, 61supplied with connection profiles, which for simplicity is not shown in the figure 1. Preferred examples of the implementation of the connecting profile can be seen in figures 2-5.

On figure 2 in cross section showing the first embodiment of the connecting profile 7, 71and in the upper part of figure 2 connection profiles 7, 71connected to each other and in the lower part of figure 2 they are shown separately from each other. The connecting profile 7 has a groove 8, which is formed by the lower rim 9 and the upper rim 10. The connecting profile 71has a spike 11, which can be inserted into the groove 8 (see upper part of figure 2). Spike 11 has a bottom side 12 and the upper side 13, which question yaytsa mainly parallel to the plane of laying, which must meet the laminate panels 1, 2.

The lower rim 9 forms a first side wall 14 of the groove, which communicates with the bottom side 12 of a stud 11 when connecting profiles 7, 71connected to each other. Top notch 8 is limited to the second side wall 15 of the groove. In the United state profiles 7, 71the upper side 13 of the spike 11 is adjacent to the second inner wall 15 of the groove. Thus, the connecting profiles 7, 71connected in the direction D1 perpendicular to the plane of installation.

The bottom side 12 of a stud 11, for example, forms a surface which interacts with a mating surface in the form of a first inner wall 14 of the groove when the connecting profiles 7, 71connected to each other. Bottom 12 provided with a layer 16, which increases the friction. Increasing the friction layer 16 contributes to the fact that increases the frictional force between the bottom side 12 of a stud 11 and the first inner wall 14 of the groove 8, which in the United state of connecting profiles 7, 71prevents the separation of these connecting profiles. When this frictional force counteracts on the one hand the movement of the separation in the direction D2 and on the other hand the movement in the direction D3, which extends in the longitudinal direction of the connecting profiles 7, 71and on figure 2 in the plane of line is. Plane stacking E is determined by the directions D2, D3. In the example implementation figure 2 increase the friction layer 16 is provided not only on the bottom side 12 of a stud 11 and the second inner wall 15 of the groove 8. Also, and this increases the friction layer 16 on the second inner wall 15 of the groove serves for connecting the profiles 7, 71were strongly connected to each other. Additional increases friction layers 16 may be arranged on the upper side 13 of the groove 11 and the first inner wall 14 of the groove.

In the figure the connection profiles 7, 71shown in an enlarged scale. In the figure 3 in contrast to figure 2, however, shows only increase the friction layer 16 on the bottom 12 of the groove 11. Increasing the friction layer 16 in the form of layer 17 obtained by flocking, which includes a core layer 18 and a large number of short fibers. The core layer 18 serves as the mounting of the individual short fibers on the bottom side 12 of the cleat 11. Short fibers its sealed end fixed in the main layer 18. Loose or free end of the short fibers 19 extends from the base layer 18. As can be seen in figure 3, the short fibers are oriented parallel to each other. Short fibers 19 thus tilted in the direction of the DE insertion along which the tenon 11 may vdvinut'sâ into the groove 8. The angle between predominantemente short fibers 19 and the direction of insertion D Ein figure 3 labeled α. The angle α is less than 90° and is mainly from 30 to 80°. The angle α is mostly constant throughout the length of the short fibers and installed during the manufacture of the layer of short fibers.

Due to the slope of the short fiber layer 17 consisting of short fibers, is in the direction of insertion DEthe coefficient of friction RN, which is less than the coefficient of friction RHthat should be the basis when the spike 11 is pulled out of the groove 8.

Figure 4 shows another variant implementation of the connecting profiles, which are indicated by positions 20, 201. Structural elements or characteristics of the connecting profile 20, 201that are similar or identical structural elements or features of the connecting profiles 7, 71in figure 2, received the same number of positions. Also here the connection profiles 20, 201include the tenon 11 and the groove 8, which is limited in the direction D1 of the lower rim 9 and the upper rim 10. On the lower rim 9 of the molded locking element 21, which in the United state of connection profiles 20, 201(upper part of figure 4) engages in a groove 22 for fixing, which is formed on the bottom side 23 of the connecting profile 201.

To connect the connecting profile 20, 201with each other, and join the nutrient profile of the 20 1must bend relative to the connecting profile 20, as shown in the lower part of figure 4. In a bent position under the lower part of figure 4 connecting profile 201his groove 11 may be wound in a thorn 8, without having to interfere with the locking element 21. After that, the connecting profile 201rotated in the plane of the packing E, so that the locking element 21 and the groove 22 to lock engages and thus form a positive locking in the direction D2.

To strengthen the connection of the connecting profile 20, 201in the direction D2, the first side wall 14 of the groove and on the bottom 12 and the top side 13 of the groove 11 is arranged which increase the friction layers 16. Thanks this may be increased friction in the connection between the connecting profile 20, 201in the direction D2, resulting unloaded connection with a positive locking between the locking element 21 and a groove 22 for fixing. As in the example implementation presented on figure 3, increasing the friction layers 16 can be formed as a layer 17 with a short inclined fibers 19.

If the connecting profile 201inserted into the connecting profile 20, but not yet rotated into the plane of the stacking E, which increases the friction layers 16 are not engaged at all or are directly on the nom engagement, so without great effort possible displacement of the connecting profile 201in the direction D3, i.e. along the connecting profile 20, 201.

Figure 5 shows another preferred embodiment of the connecting profile, which are indicated by positions 24, 241. The connecting profiles 24, 241include two profiles 25, 26 in the form of hooks, which are constructed identically and respectively consist of jumpers hook 27 and the end portion of the hook 28. In the United state of connecting profiles 24, 241captured integral parts of the hooks 28 of the elements in the form of hooks of the connecting profiles 24, 241. To strengthen the connection in the direction D1, the end part of the hooks 28 are respectively on the outer side 29 which increases the friction layer 16. These increase the friction layers increase the friction between outer sides 29 of the end parts of the hooks 28 and a trailing wall 30 of the hook. With increasing friction layer 16 can be achieved not only a strong connection between the connecting profiles 24, 241in the direction D1, but also creates an insurance against poor performance. Besides, additionally or alternatively, as shown in figure 5, increasing the friction layers 161provided on at least one of the horizontal sides 31 of the elements 25, 26 in the form of hooks.

With p the power figures 6 and 7 must be submitted two ways, as can be stacked panels with connecting elements according to figures 1-5.

The figure 6 shows three different stages I, II, III of way, and the left part of figure 6 shows the laminate panels a, b, C on the top and right part of figure 6 shows the laminate panels a, b, C from the side.

The starting point of the method should be already laid panel A, which lies in the first row R1. In the second row R2 is the panel, which has its long edge 51connected to panel A. in Order to put the panel in the second row R2, it is at an angle to the plane E of laying this long edge 51is inserted in the connection profile on the long edge 5 of the panel A. the Connecting profiles, panels a, b, C on the long edges 5, 51must comply with the connecting profile according to figure 4. As can be concluded from the stage) method, the panel With its short edge 61located a further distance from the short side 6 panel C. phase II of the way the panel is shifted in the direction of the panel In until, until it reaches in panel C. the Connecting profiles of the panels, on short edges 6, 61must comply with the connecting profiles 24, 241figure 5. In part III how the panel fits with prihlopyvaniem in the plane E of installation, allowing the elements 25, 26 in the form of hooks (see f the guru 5) are engaged with each other.

The figure 7 shows the method of installation of panels a, b, C, and now the connection profiles on the short sides 6, 61must comply with the connecting profiles 7, 71figures 2 and 3. The image of panels a, b, C from above and from the side, and an image of the individual phases I, II, III, and IV correspond to the images of figure 6.

As in figure 5, have already been laid in the first row R1 of the panel and the already placed in the second row R2 panel To form a starting point. On the stage) method panel long edge of the 51is inserted into the long edge of the panel And, moreover, it is in an inclined position. After that, the panel is rotated from the plane E of laying the top until it reaches the inclined position of the panel C. Thus panel, lie in one plane.
