Description

The invention relates to a set of construction panels with a device for locking at least two of these construction panels together.

From DE 10 2006 006 124 A1, a device is known for interlocking construction panels joined together, in particular floor panels with a core made of wood composite or a mixture of wood-plastic compound, in a perpendicular V direction to a visible face, composed of at least one tongue element housed in the first construction panel, for clipping with automatic abrupt closure in at least one groove provided in a second construction panel, which runs parallel to the visible face, when by joining the construction panels by means of a vertical descent movement, the tongue element, of which there is at least one, and the groove element, of which there is at least one, overlap, being provided for the interlocking of both construction panels in a direction H parallel to the visible face, on a side edge I, a lower lip that protrudes laterally therefrom, with an outer shoulder, which a recess oriented towards the lower face protrudes upwards and on the opposite lateral edge II, configured corresponding to the projection and which limits with a projection oriented downwards. Such an interlocking device is preferably provided on the transverse side of the construction panels. The tongue element is composed of a bent spring steel with sinusoidal shape, with multiple undulations and is housed in a groove arranged in the core of the first floor panel. When both panels are joined together, the tongue element is first pressed into its groove and then elastically returns abruptly when the groove provided in the second panel overlaps with the tongue element. For the tongue element a commercially available spring thread can be used, which is cut from the roll to the corresponding length and bent. The forces that can be transmitted are high. The housing of the tongue elements in the grooves must be done very precisely.

From WO 2005/054599 A1, an interlocking device provided on the transverse side of floor panels is known. On the longitudinal side the panels have a tongue / groove profile that is self-locking. When laying, the new panel to be attached is attached to the set of panels already laid first on the longitudinal side with a panel already lying squarely in the groove and then sliding it in the angular position in the direction of the side edge of the previously laid panel in the same row and lowering it there. The hook-shaped profile makes one element fit into another and the tongue element then abruptly closes on the new panel to be laid. This tongue element is configured of plastic and is bevelled on its upper face. Similar to a door handle, it moves inwards and then presses inwardly through the bevel the tongue element of the new panel to tend, when it hits its lower face with the bevel and continues to move down .

From EP 1 650 375 A1 two panels are known that can be joined together, in which the interlocking element is configured as a flexible tongue element, which is integrated at its two ends, for example by dragging, in a slot made on a side edge of the first panel. In the area between these two fixing boards, the tongue element of the groove that houses it protrudes and fits into a slot provided for this purpose of the adjacent panel when both panels are joined together. During the joining of two panels, the central part of the flexible tongue element is moved into the groove that houses the tongue element. This is possible due to the specially chosen geometric shape of the flexible tongue element. Such a flexible tongue element can be manufactured, for example, in the casting process injected from a plastic.

The flexibility required for the interlocking of the interlocking element is determined by the shape of the interlocking element. Because of this, the configuration of such an interlocking element is complicated. The groove of the tongue element must also be grooved very precisely. In addition, the interlocking is carried out in many cases, passing through at least two rows, which establishes a tension. The last row interlocks the penultimate row, since by means of it a compression of the tongue element oriented out of the groove is performed.

From DE 10 2007 032 885 A1 a device is known for interlocking two panels connected to each other, in which between the tongue element and the base of the groove in which the tongue element is arranged, an element of compression acting in the direction of the tongue element, which during the interlocking process can be reversibly compressed by the interlocking element, without expanding in one direction along the groove.

From EP 1 420 125 A2 a device is known for interlocking two construction panels joined together, in which two supplements provided with an elastic lip, housed, rotated 180 °, are provided in respective grooves in each of the construction panels that constitute an upper and lower interlocking. The elastic lips can expand both in the vertical direction and also in the horizontal direction and then fit into a hook in the corresponding recess in the opposite panel, whereby the panels are interlocked. Because the elastic lips have two degrees of freedom, the tolerances in the manufacturing of the interlocking grooves can be generously sized.

Based on this problem, the known set of construction panels must be improved with a device for interlocking at least two of these construction panels. In particular, an interlocking profile must be achieved which, in terms of the complexity of the interlocking, can be manufactured in a more simple and economical way. In addition, an interlocking must be done using the profile itself.

In order to solve this problem, in this set of construction panels, in particular floor panels, a core of wood composite or mixture of wood-plastic compound is provided, which interlocks two construction panels joined together in a direction perpendicular to a visible face, has a tongue element housed in the first construction panel for clipping with automatic abrupt closure in at least one slot provided in the second construction panel, which runs parallel to the visible face, when by joining the construction plates by means of a vertical descent movement, the tongue element, of which there is at least one, and the groove, of which there is less one, overlap, being provided for the interlocking of both panels of construction in a direction parallel to the visible face on a side edge a lower lip that protrudes beyond it laterally, with an outer shoulder, that an open recess towards the lower face protrudes upwards and on the opposite side edge, configured corresponding to the projection and that limits with a projection oriented downwards, with the additional characteristics of a groove, of which there is at least one, it is provided in the projection facing downwards and is open in the direction towards the recess facing the lower face, such that the projection facing upwards has at least one recess opposite the groove, such that the tongue element, of which less there is one, it is arranged in the recess and such that the tongue element, of which there is at least one, can be compressed and / or deformed in the direction parallel to the visible face.

The recesses can be formed by horizontal grooves. The elasticity of the tongue elements can be controlled by multiple parameters, such as thickness, wall thickness, geometry, filling materials and / or the choice of material. This allows flexible adaptation to different thicknesses.

The recess is preferably configured such that it crosses the shoulder. The tongue element, of which there is at least one, may be positioned in the recess, of which there is at least one, such that it closes flush with the shoulder on the front face and penetrates the back. In the downward movement the tongue element is compressed / deformed first. When the downward movement is continued and the groove provided in the projection protruding downwards coincides with the recess of the projection protruding upwards, then it can, from a certain angle, penetrate the compressed / deformed tongue element in the groove

Preferably, the groove is practiced along the entire length of the lateral edge in the projection protruding downwards.

The tongue element can be a ring, which can be configured round or oval. The tongue element may also be composed of multiple rings joined together or in the form of a bolt.

After complete bending of both floor panels, the tongue element is no longer under tension, due to penetration into the opposite groove. The separation of two construction panels joined together can be achieved by a simple horizontal displacement of the side edges of each other. When the tongue element, after releasing two construction panels, protrudes on the front face of the recess, it is possible by a simple down / folded pressure of one of the floor panels a new joint.

The tongue element is preferably housed from the factory in the recess. To prevent it from falling out of the recess, the particular tongue element is preferably trapped in the recess. Alternatively or additionally, it may however also be stuck in the recess.

Each row of construction panels interlocks by itself and is thus protected against displacements or separation of the profile at the side edge. No further fixations are needed. The interlocking can be chosen at discretion by choosing the position of the recesses along the width of the side edge.

The interlocking process is facilitated when both projections are beveled on the sides facing each other.

An exemplary embodiment of the invention will be described in more detail below with the help of a drawing.

It is shown in:

The construction panel 1, 2, is preferably a floor panel with a core 4 of wood composite (MDF or HDF, that is, of medium density fibers or high density fibers) or of a mixture of wood compound -plastic. On the core 4 a decorative layer can be glued with, for example, a wood grain or it can be pressed with the core 4 or the decorative motif can be printed directly on the visible face. On the side edges I, II facing each other, the hook profile panels corresponding to each other are provided, whereby two construction panels 1, 2 joined together can be interlocked in a horizontal direction. For this purpose, a lower lip 12 protruding laterally beyond the lateral edge I, which has an outer projection 7, protruding upwards, is provided on the lower face 11 on the first lateral edge I. On the second opposite side edge II, a recess 13 is arranged corresponding to the shoulder 7, whereby on this side edge II a shoulder 5 is formed that projects downwards. For all the length that penetrates the plane of the drawing of the lateral edge II, it is practiced in the projection 5 which protrudes down a groove 6 open towards the recess 13. In the projection 7 protruding upwards in the lower lip 12, this made at least one recess 14 running parallel to the visible face 3 and open to both sides in the form of a groove or a hole milled. In this recess 14 is housed a tongue element 8 that can be compressed or deformed, which at its two ends protrudes from the recess 14. The outer perimeter of the tongue element 8, of which there is at least one, is larger than the perimeter inside the recess 14, whereby the tongue element 8 is trapped in the recess 14. Additionally, it can be stuck in the recess 14.

When both construction panels 1, 2 are joined together by an essentially vertical turning movement, press the wall 10 which runs obliquely on the shoulder 5 protruding downwards and in its upper area the beveled wall 15 of the core 4, the element of tongue 8. When the downward movement continues, the groove 6 in the shoulder 5 coincides with the compressed tongue element 8 or the recess 14, which then loses its tension and fits into the groove 6. To facilitate the socket, the bottom wall 6a of the groove 6 is beveled down, whereby the groove inlet is larger than the base of the groove.

The tongue element 8 is configured of plastic. It can be composed of several rings joined together. The length of the recess 14 beyond the length of the side edge I or the length of the tongue element 6 depends on the locking force to be adjusted. Multiple tongue elements 8 / recesses 14 may be provided along the entire length of the side edge I. As can be seen in Figure 2, when the construction panels 1, 2 are joined, the oblique walls 9, 10 of the Highlights 5, 7 next to each other. The projection 5 facing down then rests on the base of the recess 16 configured in the lower lip 12, resulting in a stable joint.

Figures 3 to 6 show different phases during the assembly of two construction panels 1, 2 configured according to the invention. The state according to FIG. 3 is the initial state, in which both construction panels 1, 2 are oriented towards each other and arranged one above the other such that the projection 7 protruding upwards is oriented essentially in parallel with the open recess 13 down. The same applies to the projection 5 protruding downwards and the recess 16 open upwards. The tongue element 8, which is configured as a ring and correspondingly has a free central space 18, meets the upper outer perimeter next to the oblique walls 10, 15 of the construction panel 2 lying from above. It has its maximum extension in the horizontal direction H. In Figure 3 it can be seen that the tongue element 8 protrudes on both sides beyond the projection 7 facing upwards. Unlike in Figures 1 or 2, in Figures 3 to 6 the slot 6 is not provided in the projection 5 that projects downwards, but on the side opposite to the front side edge 2 of the recess 13 open downwards. The groove 6 is then milled in the core 4 and serves to accommodate the tongue element 8.

In figure 4 the second construction panel 2 is displaced in the vertical direction V downwards, both leading edges I, II are next to each other and both construction panels 1, 2 are oriented parallel to each other. Due to the oblique configuration, converging upwards, of the oblique walls 10, 15, the tongue element 8 is compressed. This can be observed in the reduced clearance 18 in the central area of the tongue element 8.

Figure 5 shows the state in which an additional descent in the downward vertical direction has been made. The right edge of the tongue element 8 rests on the upper end of the oblique wall 15, while the left end continues to slide along the oblique wall 10. In the state represented in Figure 5, the right edge is located directly next to the bottom face of the groove 6, resulting in a minimum horizontal extension of the tongue element 8. The central clearance 18 is in the horizontal direction H with its minimum extent.

If a further descent of the second construction panel 2 is now carried out, the tongue element 8 is elastically inserted in the groove 6, the left end of the tongue element 8 resting on the anterior wall 10 of the recess 13 open downwards. The central clearance 18 increases, depending on the magnitude of the elastic return of the depth of the groove 6. If the groove 6 is deep enough, that is, if it has an extension in sufficient longitudinal direction, the tongue element 8 can be moved so Fully elastic return to its initial position. If the groove 6 is not deep enough in the horizontal direction, the prestressed tongue element 8 remains.

A perspective view of a construction panel 1 with a tongue element 8 housed is shown in Figure 7. In Fig. 7, the recess 14 in which the tongue element 8 is housed, glued or imprisoned can be clearly seen. Likewise, the upper face 3, the recess 16 open upwards, as well as the projection 7 protruding upwards can be observed. It can also be seen here that the tongue element 8 protrudes from both sides beyond the protrusion 7 that protrudes upwards. In addition to an annular shaped configuration of the tongue element 8, other geometries, for example oval perimeters, polygonal perimeters or also solid tongue elements, may also be provided throughout its surface.
