The invention relates to panels, especially floor panel, with a core of wood composite material or of a mixture of sawdust and resin material, the upper side and the lower side, while the panel includes located on the first lateral edge of the lower closing element which is located on the lower side of the panel toward the first side edge, a first transverse edge and located on the outer end of the first edge of the first hook with back undercut, and located on a second side edge, opposite the first lateral edge, the upper closing element which is located on the upper side of the panel toward the second lateral edge, second lateral edge and located at the outer end of the second ribs of the second hook, which has at least one locking shoulder so that the two are identical in construction panels made with the ability to connect and commit to each other in the horizontal direction and the vertical direction after latching the locking shoulder of one panel in the rear undercut the second panel.

A panel of this type is known, for example, from DE 19929896 A1. Two of the panels are connected to each other through passing perpendicular to the plane of laying connecting traffic. At the same time as the lower for the a priori element, and the upper closing element gradually elastically expand, until it locks into place locking shoulder of one panel in the rear undercut the second panel. Two similarly connected panels in the horizontal and in the vertical direction are connected to each other and fixed.

Force unlock is the power that you want to spend again to disconnect the two connected to each other and fixed panel, among other things, is determined by how deeply the locking shoulder of the first panel can snap into place in the rear undercut the second panel. The farther the locking shoulder is included in the back undercut, the stronger fixation of the panels. In order to achieve a strong fixation, locking elements should as far as possible to elastically expand. For this material, which consists both of the locking element must have a relatively high elasticity.

DE 10305695 A1 also describes sexual panels, which are made with the possibility of connection due to the perpendicular to the plane of laying connecting traffic. Panel on one side of the edge are performed essentially mushroom-shaped retaining bar and on the other, opposite this side edge, the side edge having essentially the form of a mushroom in the cross section of the locking groove. PR is the connection of two panels having essentially the form of a mushroom retainer strap is put into having essentially the form of a mushroom retainer groove. However, due to the mushroom shaped locking groove must elastically expand, until it locks into place with the form of a mushroom retainer strap.

Also in this case, the locking groove have to elastically expand as far as possible, in order to achieve a solid fixation of the two panels relative to each other.

DE 20203311 U1 also describes sexual panels, which are made with the ability to connect with each other through a vertical connecting traffic. It is shown there also latches the locking shoulder of one panel in the rear undercut the other panel. When this locking element of one panel should also be extended in order to ensure fixation.

As materials for the core panels are especially suitable fibrous plates medium density (MDF) or fibrous plates of high density (HDF). They have high strength, so it can withstand the loads to which they are exposed, especially when stepped on them. The negative is that these bearing materials have the capability of elastic deformation only in small degree. Because of this, the locking elements have the opportunity elastic expansion only to a limited extent. Thus the possible strength of fixation of the two panels are also limited due to the choice of the substrate material.

DE 10207015048 A1 describes a panel, in which at least one lateral edge formed elastic element, which can snap into place into the intended slot on the opposite side of the other panel. Elastic element extends along the side edges and connected to the base panel only for its both ends. Between them it is separated by two frezerovok and accordingly may be rejected horizontally. When joining two panels elastic element is rejected, and is latched in accordance with this second panel in the groove after both the panel reached a predetermined end position. Due to this, both panels are connected to each other and are fixed at least in the vertical direction.

This detent is determined by the thickness of the elastic element. Especially when thin panels elastic element must be made particularly thin, so first of all, in these cases, there can be a fix which is made is not strong enough.

DE 102007020271 A1 describes sex panel, the side edges of which are provided with a shutoff device for vertical fixing. The stopper protrusion of one panel penetrates the window panel and grabs the back covering the window wall. Due to the design of this window is formed bilateral tense traverse colorable commit is rejected, and again snaps back into the locking position.

The negative is that this yoke, which extends along the side edges of the panel connected to the panel only at both ends. Because of this laid primarily on the uneven base of the genital panels occur when the circulation pressure to cause the connection between the head plate and the core of the panel is broken. In this case, the panel is no longer fixed to each other.

Moreover, the traverse due to the fact that the locking element passes through the window, may have a thickness of only about one-third the thickness of the panel. Especially in thin panels of stability because of this greatly reduced, so that this solution is applicable only for thick panels.

Therefore, the object of the invention is to improve the panel above so that for thin panels was probably a strong and reliable connection of two identical panels with each other both in vertical and in horizontal direction.

The invention solves the problem by means known from the prior art panel, in the first transverse edge of the lower closure element is provided at least one continuous groove with a width less than the width of the second hook.

This at least one groove separates the portion of the first hook from the core in the horizontal napravleniya this first hook may be easier and farther rejected as being primarily in a horizontal direction, and again relatively parallel to the side edge of the panel axis. Due to this possible extension of the lower locking element so that the locking shoulder of the second locking element may further include the rear undercut the bottom of the locking element, allowing the connection of the two panels to each other increases.

Preferably, if at least one groove runs parallel to the first lateral edge. This ensures a simple and fast fabrication of panels of this type. Due to the location and length of the at least one groove can be very precisely adjust how far the lower closing element may be increased with the connection and the locking of the two panels to each other.

Preferably, if there are multiple grooves. This ensures that the transverse edge of the lower locking element in highly loaded areas, for example in the center of the side edge of the panel is not interrupted and thus has an increased stability.

Preferably, several grooves are located at different distances from the first side edge. Preferably, at least two grooves at least partially pass next to each other. In this way it is ensured that a transverse edge along the entire length of the side edge is interrupted by Myung is our least one groove without too much attenuation of the lower locking element.

Preferably, at least one of the grooves placed on the end of the first side edge. This increases the elasticity of the lower locking element primarily in the marginal zone.

Preferably, at least one locking shoulder on the second toe is made shorter than the second side edge.

Preferably, the second hook has several located next to each other with the locking shoulder. Preferably, the position of the at least one groove and at least one locking shoulder along the side edges match each other. This ensures that in the places where the second toe is the locking shoulder, a transverse rib on the lower locking element is provided by the groove. Due to this, it is in these places increases the elasticity of the ribs and easier deviation or extension of the lower locking element. In places where the locking shoulder is not provided, in this case also there is no groove in the transverse lower edge of the locking element, so that it is out of stability. First of all, if at least one of the grooves is at the end of the first lateral edges, and also at the end of the second side edge is provided for locking shouldered. By rotating the retraction movement of the first hook is nor can be longer than at least one lying on the end side groove.

The position and length of the at least one groove is defined, mainly, the force of the return lower locking element. The length of the at least one locking shoulder on the second toe may also change. It has a significant impact on the movement, which runs the lower closing element. If the locking shoulder is shorter than the corresponding groove, the first hook is offset mainly horizontally. If, on the contrary, the length of the locking shoulder is only slightly shorter than the length of the at least one corresponding groove, the first hook increasingly compelled to perform a rotating movement collapsed.

Preferably, the lower side of the first edge is held up at an angle α relative to horizontal. This narrowing of the lower side of the panel provides high elasticity of the lower locking element. Thereby it is possible to expand the lower locking element without affecting the stability of the edge.

Preferably, the angle α is from 0 to about 15°.

If the first side edge above the first transverse rib has a rear Podrez, the free length of the first edge increases. Due to this, it is possible to widen the lower closing element, if you want to connect and CBL is to kirabati with each other two identical panels.

Rear undercut can be performed, for example, in the form of a groove, primarily rectangular in cross-section of the groove in the first side edge above the first transverse edge.

The first side edge and second side edge of the proposed panels may have respectively a horizontal joint face. By means of these connecting faces on one side edge of the notch is formed, and on the opposite lateral edge of the panel is formed corresponding protrusion. While laying and connection of two panels protrusion enters the recess. Due to this positioning of the vertical panels when laying is not dependent on the actual locking mechanism.

Further examples structural embodiment of the invention are described more with reference to the drawing.

Figure 5 is a partial section view of two panels according to the but the fourth example of structural embodiment of the invention under examination.

Figure 6 is a partial section view of two panels according to the fifth example of structural embodiment of the invention under examination.

Figure 7 is another example of structural embodiment in accordance with figure 4.

In figures 1A-1B shows the various stages in the process of joining two identical panels. For the first panel 1 shows the first side edge 2, and the second panel 3 - the second lateral edge 4. On the bottom side 6 of the first panel 1 is the lower locking element 8. The lower locking element 8 has a protruding above the first lateral edge 2 first transverse edge to the outer end of which is a first hook 12 and which has a groove 26.

On the upper side 14 panel 3 has an upper locking element 16. The upper locking element 16 includes protruding above the second side edge 4 a second transverse edge 18, the outer end of which is a second locking element 20.

The first hook 12 of the lower locking element 8 has a rear undercut 22. The second hook 20 has a corresponding locking shoulder 24.

Shown in figure 2-example of structural embodiment in the first transverse edge 10 of the lower locking element 8 made two grooves 26. In the transverse rib 10 in parallel to each other can also be several grooves 26, as shown in figures 5 and 6. Oncoprecipitin provided respectively only one of the through groove 26.

In figure 1A, both panels 1 and 3 show before you commit. They should be placed in relation to each other so that the fixation can be due to vertical coupling movement of the second panel 3 relative to the first panel 1.

Figure 1B shows both panels 1, 3 during the commit process. In contrast to figure 1A, the second panel 3 relative to the first panel 1 is omitted. This second hook 20 provides that the lower locking element 8 extends. The first hook 12 can perform a horizontal movement to the left and rotate relative standing perpendicular to the plane of the drawing axis. This is possible due under the first transverse edge 10 of the lower locking element 8 of the groove 26.

In figure 1B, both panels 1, 3 are fixed to each other. When this locking shoulder 24 of the second hook 20 clicks into place in the rear undercut 22 in the first hook 12. The first hook 12 has ambrogini back to its original position.

The first hook 12 extends throughout the length of the first lateral edge 2. It can be manufactured in a simple manner, for example by means of a stationary tool on the principle of stationary blades, the movement of the workpiece is used to remove shavings. Actually the lower locking element 8 is made, for example, using one or more nepodvedomstvennyh, rotating milling tools. Grooves 26 can also be simply made by means of a rotating milling tool, which during the movement of the panel pivoting motion is immersed in the material panel and comes out of it. Alternative you can use such other methods such as laser cutting or die cutting. Production may occur continuous or periodic (in clock mode) method.

In the example shown constructive perform the locking shoulder 24 of the second hook 20 extends not along the entire length of the second side edge 4. Its length corresponds to the position of the grooves 26 in the first transverse edge 10. This ensures that the elasticity of the lower locking element 8 increases exactly where you want the deviation of the first hook 12 to lock the two panels 1, 3. In places where the locking shoulder 24 is not provided, the lower locking element 8 has full stability. The locking shoulder 24 is, for example, by a fixed tool. The number of locking shoulder 24 corresponds to the number of grooves 26 (see figure 2).

To lock and connection of the two panels of the second hook 20 through the deflection of the second panel 3 is wound in the first hook 12 on the first panel 1. When this locking shoulder 24 rejects p is pout hook 12 as long while not cross it. It is provided or facilitated by stipulated in the first transverse edge 10 of the grooves 26. Immediately after this, the first hook 12 is moved to its original position, allowing both panels 1, 3 are fixed in both the horizontal and vertical directions. If there are multiple locking shoulder 24, rejecting the second panel 3 locking shoulder 24 is locked at the locking lug 24 so as to form a connection type "lightning".

The figure 2 shows a schematic top view of the panel 1. On the first lateral edge 2 formed of the lower locking element 8. In turn, this lower locking element 8 has a first transverse edge 10 and the first hook 12. In the shown design example running in the first transverse rib 10 is provided with two grooves 26, which are located on the respective ends of the first lateral edge 2. This increases the elasticity of the lower locking element 8, especially in the marginal zone. Preferably, not shown on the opposite lateral edge is provided associated with them fixing shouldered, are also located in the outer edge areas of the side edges.

Figure 3 shows the cross section along the line III-III in figure 2.

On the bottom side 6 of the first panel 1 is lower stop e is ement 8. In the first transverse edge 10 of the lower locking element 8 is provided with the groove 26.

So the bottom side 28 of the first edge 10 is held up at an angle α relative to horizontal. Due to this additionally increases the elasticity of the lower locking element 8 without additional deterioration of the stability of the first edge 10. This way you can continue to reject the first hook 12 when connecting two identical panels. Preferably, the angle α is from 0 to about 15°.

Figure 4 shows a partial section view of two panels 1, 3 before connection. As in figure 3, on the bottom side 6 of the first panel 1 is first shut-off element 8, the first transverse edge 10 which has a bottom side 28, which passes up under the unmarked angle α relative to horizontal H. When connecting panels 1, 3 first hook 12 is again rejected up until the locking shoulder 24 on the second toe 20 snaps into place to detect the rear undercut 22 on the first hook 12. Panel 1 at its first side edge 2 has a horizontal connecting line 30. The second side edge 4 of the second panel 3 is also provided with horizontal connecting line 30. Both horizontal joint face 30 is made so that in the United and recorded the condition of the panels 1, 3 they are adjacent to each other is thus formed by a horizontal connecting line 30, located on approaching the top panel 3, the protrusion is formed in the horizontal connecting line 30 to the first panel 1 dredging. This ensures that the positioning of the panels 1, 3 does not depend on the actual locking mechanism.

Figure 5 shows a partial section view of two panels 1, 3 according to a fourth example of structural embodiment of the invention under examination. As described in the above examples, the structural embodiment, on the bottom side 6 of the first panel 1 is the lower locking element 8. In the first transverse rib 10, the bottom side 28 which also goes up at an angle α to the horizontal H, there are two grooves 26. For fixing the second hook 20 of the upper locking element 16, which is located on the upper side 14 of the second panel 3, includes a first hook 12. The first panel 1 at its first side edge 2 has a rectangular groove 32, which additionally increases the freedom of movement of the lower locking element 8 and thereby the first hook 12. In this way it is ensured that the first hook 12 when the fixing of the two panels 1, 3 can be rejected without further negative impact on the stability of the first edge 10. In figure 6, the same effect is provided a rear undercut 34, which is provided in the first lateral edge 2 of the panel 1. In this way increases its is odna length of the first edge 10 so, the first hook 12 when the fixing of the two panels 1, 3 can be rejected without further negative impact on the stability of the first edge 10.

Also in figure 6 the lower side 28 of the first edge 10 is held up at an angle α relative to the horizontal N.

Shown in figure 7-example of structural embodiment of the contact surfaces 35, 36 of the first and second hooks 12, 20 are under the direction toward the horizontal by the angle β. In such constructions the commit process flows with less effort.
