The invention relates to panels, especially floor panel core wood composite material, the upper side and the lower side, and the panel has at least two located at opposite lateral sides is corresponding to each other profiling that two identically made panels made with the ability to connect and interlock with each other in horizontal and vertical direction by essentially vertical connecting movement with the lock in the vertical direction to achieve through at least one is arranged to move in a horizontal direction of the elastic element, which when the coupling movement is latched for extending essentially in horizontal direction the locking edge.

A panel of this type is known, for example, from EP 1 650 375 A1. Executed on this panel lock type (circuit) is preferably provided on the lateral side of the floor panel. However, the lock may be provided on the longitudinal side, or as on the longitudinal side and a transverse side. Spring element consists of plastic and is inserted in a horizontally passing through the groove on one side and on its upper side has a beveled edge. Counterparts is but a door hinge spring element due to the beveled edge is pressed a new dockable panel, when she its lower edge lays on the bevel and it goes on. When the new imposed by the panel fully descended to the ground floor, the elastic element is snapped into the groove made on the opposite side. To make this elastic element necessary special tools for injection molding, whereby the production is quite expensive. In addition, to achieve sufficient strength values should be used in high-quality plastic, which further increases the cost of springy element. If you use plastic with too small values of strength, this leads to too large deviations springy element from the nominal dimensions, because only by this it is guaranteed that can be formed or transferred by the corresponding forces.

Due to the fact that the locking element is designed as a separate part, give rise to additional costs. Because of the technology of manufacture of the locking element is spatially remote from the panels so that the integration in the continuous process of production, primarily panels for flooring, is likely impossible. Due to different materials, chipboard materials, on the one hand, and plastics, on the other hand, bringing in the response of the manufacturing tolerances of two separate production processes is expensive and costly. Since the locking in the vertical direction in the absence of the locking element would be inefficient, the locking element must be, in addition, secured against falling out is made on the side edge of the groove when the further manufacturing processes and transportation. This protection is also costly. An alternative to this, the locking element could be provided to the consumer available separately.

Increasingly referred to sexual panels are laid (laid on the floor) with non-professionals so that due to the missing experience fundamentally there is a possibility that the original desired number of locking elements is determined incorrectly, and they are purchased in sufficient number in order to comply fully with the laying indoors. In addition, it is possible that when inserted into a springy elements layman makes a mistake that leads to the precise arrangement impossible and connection over time breaks down that refers the consumer to the account supplied by the manufacturer.

From DE 102 24 540 A1 famous panels that are located on opposite lateral sides profiled so that the formed hook fasteners to lock in the horizontal direction. To lock in the vertical the actual direction on the connecting elements are provided spaced from each other in horizontal and vertical elements with geometric circuit and corresponding recesses, each of which is directed horizontally locking surfaces. Transverse tensile directed in such a way horizontally locking surfaces is about 0.05 to 1.0 mm in order For the coupling of two panels generally remained possible selection of sizes should be small. However, thus inevitably there is a situation that can be perceived only minor directed vertical forces. Thus, it is the manufacturer with extremely small tolerances in order to ensure that under normal load, the connection will not disintegrate (out of gear) on the already light unevenness in the floor and/or soft clay.

Based on the problems outlined above, the panel should be improved.

To solve this problem are known from the prior art panel differs in that the elastic element is integrally made of a core.

By virtue of such execution production is greatly simplified. Time and the manufacturing costs are reduced due to the lack of need to connect and hold various items. In addition, the end user is guaranteed that all details and possibilities for further work.

Mainly at least one elastic element is free with respect to the core in the direction in which rhna side and in the direction of the opposite side face and connected to at least one of its both ends, mainly at both ends, with the core in the direction of its lateral faces. Using the dimensions of the effective connection of the elastic element core may be selected elastic elasticity.

Release (opening) of the elastic element occurs mainly through horizontal and vertical groove. Using the width of the groove define not only the strength of binding of the elastic element to the core material, but also by choosing the width of the vertical groove can be obtained for the elastic element, the emphasis in the horizontal direction so that the item is securely protected from pererasseyaniya. If the length of a lateral side there are several located at a distance from each other elastic elements, increases the stability of the connection due to the fact that limited free elastic to move in the longitudinal direction of the elastic element. The distance between the individual elastic elements can be chosen more or less large. The smaller this distance is, the more certainly effective surface, with which the lock so that the transmitted power in the vertical direction are correspondingly large.

Horizontal lock is preferably carried out by means of matching krukovich elements, with the hook element on imouse the locking edge of the side face is made by the speaker in the direction of the upper surface of the ledge, and the hook element having elastic element side through directed towards the bottom side of the ledge.

If the outer edge of the elastic element is inclined at an angle goes to the top surface, thereby facilitates the coupling movement, since the elastic element elastically deforms with increasing moving inwards towards the core of the panel.

Passing essentially horizontally locking edge is mainly lateral wall is made in the side face of the groove.

Passing essentially horizontally locking flange may be, however, performed by protruding outward protrusion acting on the ledge.

To achieve the secure lock in the vertical direction acting down the ledge may be at least partially flat end surface, which ends in the same horizontal plane as made on the opposite side of the contact surface so that the two interconnected panels rely on each other.

If the hook elements are designed so that at the junction of two interconnected panels creates a pretensioning, the side faces of the panels in the area of the upper surface are pressed to each other with their vertical is locaste, thereby achieving the connection of the upper surfaces of the panels and prevents the formation of cracks.

Panels 1, 2 are made identical. They consist of a core of wood composite material or a mixture of plastic and chipboard material. Panels 1, 2 in their spaced opposite side edges I, II, profiled, and the side I was treated by milling from the top side I and side II - from the bottom side 19. On the side II is made of the elastic element 3, which was formed by milling the core 17 with a horizontal milling groove 11 and essentially passing ve is cicalino groove 10. The side faces I, II have a length L. In the longitudinal direction side face II of the elastic element 3 at its ends 3A, 3b connected to the core material. Department of the elastic element 3 from the core 17 is exclusively due to the grooves 10, 11. The outer edge 3C of the elastic element 3 is inclined to the upper side 18 of the panel 2 at an angle α. Vertical surfaces of the side edges I, II processed in such a way that in the area of the upper side 18 is formed surfaces 15, 16 seal.

On the side I located opposite the elastic element 3, the panel 1 is equipped with extending essentially in the horizontal direction by the groove 9, the upper side wall of which forms a passing essentially horizontally locking edge. As shown in the drawings, the bottom of the groove 9 extends parallel to the outer edge 3C of the elastic element 3, which facilitates the manufacture of the groove 9. However, it could also be done in the vertical direction or angle, deviating from the angle α.

Lock the two panels 1, 2 in the horizontal direction occurs through manual profiling performed by milling krukovich elements 20, 21, and in the vertical direction via the elastic element 3 in combination with the locking edge 4 of the groove 9. Stretching down the ledge 5 of the hook element 21 is executed on minicamera partially flat end surface 12, interacting with custom " kriuk " item 20 on the opposite side of the first surface 13 of the seal, which is located below the ledge 6. The end surface 12 and the contact surface 13 terminate in the same horizontal plane E so that the interconnected panels 1, 2 are based on each other. Profiling krukovich elements 20, 21 are chosen so that at the connection point is created pretensioning and vertical surfaces 15, 16 of the adjoining panels 15, 16 are pressed to each other so that the upper side 18 of two interconnected panels 1, 2 there is no visible gap. To facilitate the joining of the panels 1, 2 to the edges of the speaker up to the ledge 6 of the hook element 20 and the speaker down ledge 5 hook element 21 is made of a facet, or they are rounded. To facilitate the manufacture of the elastic element 3 can either horizontal groove 11 (Figure 4), or passing essentially vertical groove 10 (5) to be continuous, i.e. to extend the entire length of the side face II.

Panel 2 connect with already lying on the basis of a floor panel 1, during which the panel 2 is applied to a side face of the first panel 1 and is lowered towards the base floor by essentially vertical connecting traffic. When the elastic element 3 is concerned with its lower edge d of the upper side 18 of the panel 1, further connecting the movement he, due to his passing at an angle α of the outer edges 3C in contact with the surface 15 of the seal is pressed in the direction of the core 17 so that it is deflected in the horizontal direction N. Panel 2 drops further down. Upon reaching the elastic element 3 position opposite the groove 9 in force inherent in the material returns forces he served back and sets (latched) in the groove 9, where it is adjacent its essentially horizontally passing the upper side of the 3rd to the locking edge 4. Simultaneously, the hook elements 20, 21 are engaged up until the end surface 12 comes to rest on the surface 13 of the seal. After that, the panels 1, 2 are connected and locked to each other. The inner wall 10A of the groove 10 serves as the elastic limit of the stroke of the elastic element 3 to prevent that, due to too deep immersive move the connection of the elastic element 3C core 17 at the ends 3A, 3b will be broken. Surface, i.e. the height and width, which ends 3A, 3b are connected with the core 17, determine the degree of elasticity of the elastic element 3. As shown Fig and 9, along the length L of the side faces II can be performed several elastic elements 3. On Fig and 9 shows the elastic element 3. Quite who is one, that the elastic elements 3 are shorter and there are five, six and even seven or more elastic elements 3.

As shown in Fig.6 and 7 example structural implementation of the elastic element 3 is made on the bottom side 19 of the panels 1, 2. The locking edge 4 side I made through the protrusion 8 on the ledge 6. Also in this case, the release of the elastic element 3 is passing through essentially in the horizontal direction H of the groove 11 and held in the vertical direction V of the groove 10. Also here one of the grooves 10, 11 to simplify the method of manufacturing may extend along the entire length L of the side faces II. In this constructive embodiment, the side surfaces 15, 16 are processed so as to form a hollow pocket 14, while on the side I provided protruding into the core 17 of the undercut 7.

If vertical groove 10 is made sufficiently narrow, it is also possible that the elastic element 3 remains connected with a core only at one of its ends 3A or 3b. This is illustrated in the top view in figure 9. This embodiment has the advantage that the elastic element 3 can be extended in the direction of the length L of the side faces II. Then the free end 3A or 3b is based on the internal wall 10A of the groove 10.

Cut the elastic element 3 is presented in figure 2 and 3 panel, 2 through moved transversely to the direction of the processing tool. As the tool can be used milling tools, laser or water-jet cutting or fixed cutters or pulling. In each of the shown in figure 4 and 5 constructive examples require only one roaming the tool so that each of the other releases can be made through the normal fixed instruments. This reduces nonliberalized plot, which integrally connects the elastic element 3 with the core 17. Through this you can also set different power locking forces. All constructive examples, the block is split by the fact that the panels 1, 2 are moved relative to each other along the side edges I, II or by lateral insertion into connection not shown unblocking pin.

Usually on the top side 18 of the panel 1, 2 is provided with decor that can be printed directly on the top side 18. Typically the decor is covered with a protective wear layer, which can be displaced corresponding to the decor structuring.

The above-described type of lock is provided preferably on the transverse side panels 1, 2, which in their longitudinal side can be soy is inany with each other by inserting at an angle and lowering on the basis of sex, as described in DE 103 24 540 A1. However, this profiling is possible both on the longitudinal sides and the transverse sides so that the panels can be connected to each other on all lateral sides by only vertical connecting traffic.
