Description

paneling

The invention relates to a panel with a panel core, egg ner panel top with a wear layer, a Paneelun terseite and with pairs of opposite panel edge provided edge pairs, wherein at least a first edge pair is provided with complementary locking means, of which a locking means on a groove side of the edge pair Locking groove and the complementary locking means is configured on a spring side of the edge pair as a locking spring, which fits formschlüs Sige with the locking groove, so gleichar term panels are locked together, the Verrie gelungsfeder a first panel under tilting the ses panel to the locking groove of a second gleichar term Paneels is attachable and then by a rotating joining movement of the panels relative to each other both panels are positively interlocked with each other, so that the achievable positive locking a disengagement of the v Errie apply panel edges counteracts and in a rich direction, which lies in the plane of the locked panels and at the same time perpendicular to the locked panel edges, with the proviso that the locking groove has an upper groove wall with a free end, and that at the free end an abutment surface is provided, that provided with the Verriege ment spring panel edge above the locking spring has a counter-abutment surface which, when the panel edges are locked together, cooperates with the abutment surface of the upper groove wall.

Panels of the type mentioned are used, for example, for the production of coverings for building structures, in particular other building surfaces, such as a wall, ceiling or floor. Thus, a wall cladding, ceiling cladding or a floor can be made.

The interaction of abutment surface and counter surface be limited the way by which the locking spring in the Verrie gelungsnut into it. The mating offense

che / counter-impact surface forms almost a stop. It prevents the locking spring from penetrating deeper into the locking groove; the locking spring could otherwise act as a wedge and cause a widening of the same by a deeper movement into the locking groove.

From W02007 / 081267 Al generic panel is known which has a panel core with locking means. The panel core should be made of moisture-sensitive material and it is provided with locking means. In addition, the known panel on its panel top has a useful layer in the form of an elastic surface layer. In the area of the elastic surface layer sealing means are provided to prevent the penetration of moisture down to the panel core.

The structure of the known panel appears consuming. Apart from that, a precise joining movement is required, on the one hand to assemble the locking means and on the other hand, the sealant to get into each other exactly.

The invention has for its object to simplify both the panel, as well as the joining movement, so that the United locking and the seal succeed easier.

According to the invention the object is achieved in that groove side protrudes at the free end of the upper groove wall, a sealing web that the sealing web surface has an upper Stegflä surface, which is directed to the panel top that upper half of the locking spring, a sealing groove is provided with a directed towards the bottom panel sealing surface, and that in the assembled state of two locking medium, the web surface rests against the sealing surface and achieves a sealing effect.

The measure reduces a capillary action which acts on a superficially applied liquid as it passes between the abutment surface and the counter-abutment surface. Normatively, for example, so-called laminate panels for the construction of floors, a gap between the abutment surface and the counter-impact surface max. 0.2 mm. If e.g. Water reaches deeper between the interlocked panel edges is achieved by means of the additional sealing land, the web surface sealingly cooperating with the sealing surface of the log processing groove, a seal. The web surface and the sealing surface are coordinated by their size and order in a certain way. The purpose is that they always overlap, in particular even then overlap minimally when the maximum possible gap has formed between abutment surface and counter-impact surface.

A sealing effect is still present. To the sem purpose, the panel edges are prepared so that a height offset is avoided to avoid a perpendicular to the panel top to mes sent gap between web surface and sealing surface. This can e.g. When milled Ver locking means are ensured by the with the sealing web and provided with the sealing groove Kon structure are each milled by a single one-piece tool.

The panel may in principle be formed with an odd or gera number of panel edges. Preferably, the panel has an even number of panel edges, and more preferably it has four panel edges that form two edge pairs.

Preferably, all edge pairs are identical, so that at all panel edges to which other panels can connect always a waterproof as possible he can be targeted.

In contrast to the prior art is for the useful layer, a wider range of materials available because unlike the prior art in the field of useful layer no sealant must be arranged, other materials can be used. As a material for the wear layer comes, for example, vinyl, films,

Lacquer, etc. Films are expediently semicrystalline thermoplastics, such as polypropylene (PP), polyethylene (PE), polyurethane (PU), polyethylene terephthalate (PET), etc., or amorphous thermoplasts, such as polyvinyl chloride (PVC), polystyrene (PS), or others. It is also possible to produce a wear layer of a thermosetting material, e.g. Aminoplasts, thermosetting resins, such as melamine resin. In common panels for Lami natfußboden is often a wear layer of duroplasti cal material used.

Simply, at least the sealing web and / or the sealing groove is integrally formed from the material of the panel core.

Alternatively, the sealing web can also consist of another component, which may consist of a different material than the material of the panel core. For example, the sealing web may be anextrudiert or provided as a separate construction part, for example, a component made of a thermoplastic material.

Preferably, the sealing web is arranged below the abutment surface, or at the lower end thereof.

The sealing groove is suitably arranged below the surface Gegenstoßflä, or at the lower end thereof.

The groove-side sealing web can with different Be executed cross-sectional shapes. It can be designed as a sharp cross-section or alternatively, for example, as a semicircular or semi-oval cross-section. Suitably, the cross section of the web is suitable for a single-angle joining operation, in which a first panel is inclined at this Pa neels to the locking groove of a second similar panel and then by a rotating Fügebe movement of the panels relative to each other form-locking lock both panels together, what is called "Einwinkeln" be.

The cross section of the sealing groove may be larger than the cross section of the sealing web. However, the position of the land surface relative to the panel top must be accurately machined to desirably contact the sealing surface of the seal groove when two panel edges are locked. The positional accuracy, as far as the position of the web surface relative to the panel top side and likewise the position of the sealing surface relative to the panel top side can be determined, for example. be machined with milled contours on the milling tool, so that a perfect fit joint between rule bridge land and sealing surface can be achieved.

If a quadrangular panel has two pairs of edges, each provided with the proposed locking means, then it is suitable for locking the panel edges of both edge pairs by the method of angulation with a neighboring panel.

In principle, the proposed solution also permits a recapture of a floor, i. disassembly of interlocked panels and reuse. They can be relocated and locked again.

The sealing groove may have a cross section in which at least one groove base has a curvature, expedient a kon kave curvature. In addition, the groove walls can also be be bulging.

Furthermore, it is useful if the locking groove on egg ner lower groove wall has a proximal inclined surface, and that on the underside of the spring a proximal co-inclined surface is provided, wherein by means of co-inclined surface and the inclined surface in the assembled to stand the locking means a bias can be generated, which forces the panel edges against each other.

The panel core may include a high density fiberboard (HDF).

Alternative materials for the panel core are other wood materials, e.g. MDF, chipboard, OSB board or composite materials such as wood-particle composite, English: Wood-Plastic-Compound (WPC), mineral-bonded materials or plastic-based materials that are monolithic or have a multilayer structure (layer structure) may be, wherein the individual layers may be identical or different materials.

Furthermore, it is useful if the top side of the panel is provided with edge breakage at least at one of the edges of the panel.

The edge breakage is expediently an edge breakage produced without cutting and produced only by material compaction (pressing).

Alternatively, the bevel can also be milled and provided, for example, with an edge hydrophobization or edge coating. As a coating, for example, a paint in question or a film, such as the above-mentioned examples of a film. By means of an edge coating, for example an edge hydrophobic treatment, edge coating or edge sealing, a reduction of the swelling properties of hygroscopic carrier materials can be effected, whereby the profile is shaped. remains stable and thus maintains its sealing effect.

It is also possible to recompact / deform the chamfer, e.g. by the influence of heat and by means of a fixed or rotating tool.

The edge refraction is simply designed as a chamfer. Of course, alternatively, a radius, a step, etc. may be provided as edge refraction.

It is also provided the alternative to provide the complementary locking means with an adhesive, such as glue, to improve the connection. Appropriately, a waterproof adhesive is used. The additional contours of sealing web and sealing groove then increase the wettable surface. As a result, after setting of the adhesive in a strength test of the United locking even higher pull-out forces can be achieved than without bonding.

In the production of a covering on a building surface, it is common to join panels in successive rows of panels with a certain offset to one another, so that the panel tops or the wearer layers of the panels form a common surface. Because of the arrangement of the panels with offset the joints (Längsfu ge and transverse joint) encounter T-shaped together, one speaks of T-joint. Particularly in the case of a floor made of panels according to the invention, the seal has a particularly helpful effect. If, for example, water is in the area of a T-joint on the common surface, then the contours, ie the seal pairing of the sealing web / sealing groove counteract penetration of water or a passage of water to the underside of the panel, respectively down to the ground the lining is arranged. In the area of a T-joint, the contours of the Dichtungspaa tion, which belong to a longitudinal joint T-shaped together with the corresponding contours of the seal pairing, which belong to a transverse joint, ie the seal pairing of the transverse joint extends almost to the center of the T-joint, where the cross meet at the joints.

The invention is illustrated by way of example in a drawing and described in detail with reference to several figures. Show it:

1 shows a detail of two panels with panel edges with complementary locking means in verrie apply state,

2 shows a second embodiment with reference also a section of two panels with panel edges with complementary locking means in verrie apply state,

Fig. 3 shows a third embodiment based on a white direct section of two panels with panel edges with complementary locking means in verrie apply state.

In Fig. 1 shows a panel 1 with a panel core 2, a panel top 3 with a wear layer 4 and a panel underside 5 and paired with complementary tary locking means 6 and 7 at opposite panel edges 8 and 9.

One of the panel edges 8 has a locking groove 10 as a locking means 10 and the opposite panel edge 9 is provided with a locking spring 11. Fig. 1 can be regarded as a representation of a single panel which is severed. This shows that the complementary locking means of the opposite panel edges to match and in the separated state of the panel miteinan can be connected. In practice, it comes with example when using rectangular panels with Longitudinal and transverse sides suggest that there is a wall at the end of a laid pawn row and there is no room left for an entire panel. Then the last panel is shortened on a transverse side pas send and severed for this purpose. The rest of the panel can then be used to start a new row of panels. In principle, however, FIG. 1 could also be two panels of the same type, which are each shown here in sections.

The locking groove 10 is bounded by an upper groove wall 12 and by a lower groove wall 13, wherein the lower groove wall distally further from the panel edge 8 protrudes than the upper groove wall.

The locking groove 10 has on the lower groove wall 13 on a first proximal inclined surface 14, the spring 11 cooperates with the Verriege to counteract a movement apart of the locking spring backwards from the locking groove 10. The inclination of the first inclined surface 14 is provided so that the level of the inclined surface towards the panel core decreases.

The upper groove wall 12 has a free end 15 on which an abutment surface 16 is provided. The abutment surface is arranged perpendicular to the panel top 3.

Between the panel top 3 and the abutment surface 16, an edge break 17 in the form of a chamfer 17 a is formed. The chamfer has been produced in the present example without removal of material, merely by pressing and compacting the panel core 2.

At the lower end of the abutment surface 16, a sealing web 18 is provided, which projects beyond the abutment surface 16 in the distal direction. The sealing web 18 has an upper Stegflä surface 18 a, which is directed to the panel top 3.

Above the locking spring 11 is a sealing groove 22nd provided with a directed to the panel bottom 5 sealing surface 22a. In the assembled state of two Ver locking means 6 and 7, the web surface 18a abuts against the sealing surface 22a and achieves a sealing effect.

The locking spring 11 has a spring bottom 19, which is positively connected to the lower groove wall 13 of the locking groove 10 in engagement. In order to cooperate in the desired manner with the locking groove, the spring underside 19 has a proximal co-inclined surface 20, which is in contact with the inclined surface 14 of the lower groove wall 13 and thus counteracts a movement apart of the locking spring 11 backwards out of the locking groove 10.

Above the locking spring 11, the panel edge 9 is provided with a counter-abutment surface 21, which is in the present exemplary embodiment perpendicular to the parallel top 3 angeord net and in the assembled state of the locking means 6, 7 with the abutment surface 16 of the upper groove wall 12 in contact. The two contact surfaces 16/21 act together as a stop.

Spring side, above the locking spring 11 and un below the counter-abutment surface 21, a sealing groove is provided. This is arranged so that the groove side provided sealing web 18 protrudes when the locking means are joined together. Seal web and seal groove are integrally formed from the material of the panel core 2.

Between the panel top 3 and the abutment surface 16 is also an edge break 23 in the form of a Ver seal of the panel core 2 generated chamfer 23 a formed so that with the chamfer 17 a of the groove side panel edge 8 in the assembled state of the locking means a V-groove 24 at the Panel top yields, respectively at the wear layer 4. Appropriately, the cross section of the sealing web 18 is suitable for a single-angle joining operation, in which a first Pa neel oblique position of this panel to the Verriege ment groove 10 of a second similar panel is attached and then lock by a rotating joining movement of the panels relative to each other both panels form-fitting with each other , which is called "Einwinkeln" for short.

An alternative embodiment is shown in Fig. 2 Darge. In this improvement, the profile shape of the sealing ridge 18 has been changed and the profile shape of the sealing groove 22 also. In particular, the length of the seal land 18 and the depth of the seal groove 22 have been changed. In addition, at least partially, the thickness of the sealing ridge 18 has changed as well as the width of the sealing groove 22. In particular, the depth of the special sealing groove 22 in relation to the length of the sealing ridge 18 is made larger. This causes the free end of the sealing web 18 can not, as in the previous embodiment, abut the groove bottom of the sealing groove 22. This measure ensures that always the abutment surface 16 and the counter-impact surface 21 serve as unambiguous stop, the intended limits the joining movement and intended, an end position of the panel edges 8 and 9 defined relative to each other. This makes it easier to produce the panels accurately, so that the function of the seal can be guaranteed. Although contact between groove bottom and the free end of the

Sealing web 18 is missing and there is a small cavity 25 at each ner point, at least as good sealing effect is achieved in the embodiment of FIG. 2, as in Fig. 1. The sealing effect of the sealing web 18 takes place only on the top, d. H. the web surface 18a causes in contact with the sealing groove 22, the seal.

To adjust the sealing effect, the size of the web surface 18 a can be dimensioned accordingly. If the log web 18 is formed further protruding, which is Web surface 18a larger and with a correspondingly enlarged th / recessed sealing groove 22 can the Dichtungswir effect increase further. Moreover, the sealing effect achievable between the abutment surface 16 and the counter abutment surface 21 is better because they are better in contact with each other than in the previous embodiment.

Furthermore, the oblique surface 14 provided on the lower groove wall 13 is extended upward and enlarged. The groove wall 13 is therefore formed at the free end overall higher, which creates higher locking forces. An off moving the panels in the horizontal direction is counteracted in this way stronger. The locking spring 11 is better kept in the locking groove 10, when external forces act in opposite directions.

The embodiment of FIG. 3 is based on that of FIG. 2. Compared with this, it differs by a ande re design on the inside of the lower groove wall 13 and adapted thereto design of the spring bottom 19 of the locking spring 11. The inside of the lower groove wall is namely provided with a flat support surface 13a and the lower spring surface 19 of the locking spring eleventh has a matching flat spring lower surface 19a. The support surface 13a is in the example of Fig. 3 parallel to the Pa neeloberseite 3 arranged (horizontal). Alternatively, the support surface 13a could be arranged slightly inclined from the horizontal. The level of the locking spring 11 in the vertical direction relative to the locking groove 10 is better defined due to the planar design of the support surface 13 a and the matching flachne design of the spring bottom 19 a. In addition, the load capacity is improved in the manner and for the purpose that at a load from above, for example, if people are on the panels, a height offset locked panel edges can be better entge genge effect. In order to further improve the locking forces against a moving apart of ver bolted panels over the embodiment of FIG. 2, the angle of the proximal inclined surface 14 is steeper by about 30%, ie in comparison to FIG. 2, the inclination of the inclined surface 14 closer to the solder on the panel top 3.
