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

A panel of this type is known, for example, from DE 20112474 U1 or EP 1350904 A2.

From EP 1650375 A1 famous panel, which is not integrally made of a core. Executed on this panel lock type (circuit) is provided, preferably, on the transverse 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 vstall the n in the horizontal passing through the groove on one side and on its upper side has a beveled edge. Similarly, door hinge, spring element due to the beveled edge is pressed a new dockable panel, when 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 are plastic with too small values of strength, this leads to too large deviations springy element from the nominal size, as 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, first of all panels for flooring, is likely impossible. In the DRS different materials, chipboard material on one side and plastic on the other hand, the alignment tolerances for the manufacture of two separate production processes is expensive and costly. As the locking in the vertical direction in the absence of the locking element would be inefficient, the locking element must be additionally 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) by non-professionals, so that the effect of 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 not excluded that at the insertion of 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 10224540 AND famous panel, which are located at opposite lateral sides profiled so that the formed hook fasteners to lock in the horizontal direction. For locking in the vertical 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. So you are a 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.

Proceeding from the described problems, a method of manufacturing the panel above should be improved.

To address this problem, the method characterized in that at least one elastic element pore the STV moved transversely to the direction of the treatment tool release with respect to the core in the direction of the upper side and in the direction opposite his side and his left connected to at least one of both ends of the core in the direction of the lateral side of the panel.

Through this run 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 to the final consumer is guaranteed that all details and possibilities for further work.

Mainly that at least one elastic element is free with respect to the core in the direction of the upper 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 the side face several location is the R at a distance from each other elastic elements, increased stability 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 locking is effected, preferably, by means of matching krukovich elements, with the hook element having a locking edge side face made by a 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, as the elastic element elastically deforms with increasing moving inwards towards the core of the panel.

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

However, passing essentially horizontally locking edge can be the implementation of the Jena 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 planes, thereby achieving the connection of the upper surfaces of the panels and prevents the formation of cracks.

The following embodiments of the invention are described below with the involvement of images showing:

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 shaped, with 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 vertically 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 education is the duty to regulate passing essentially horizontally locking edge. As shown in the figures, 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 made at least 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 which oomkah acting up ledge 6 hook element 20 and the speaker down ledge 5 hook element 21 is made of a bevel 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, that is, 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 3d 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 positions in front of 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 is 10 serves as the elastic limit of the stroke of the elastic element 3 to prevent, due to the too deep immersive move the connection of the elastic element 3 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. In figures 8 and 9 shows the elastic element 3. Also, it is possible that the elastic elements 3 are shorter and there are five, six or 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 the vertical is AZ 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 of the panel 1, 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 rigidly mounted 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 shifted one relative to the other along the side edges I, II or by the side of the introduction in the connection shown, dabakarov the aqueous 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 connected to each other by inserting at an angle and lowering on the ground floor, as described in DE 10324540 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.
