Description

  • The invention relates to panels, in particular laminate panels, which can form a covering. The covering serves, for example, as a wall, floor or ceiling covering. The panels are usually made of wood, a wooden material, such as chipboard, HDF or MDF boards, plastic or plastic-like material. On the one upper side of the panels a decorative layer is provided regularly, which gives the coating the desired appearance. The decorative layer may be formed by printed paper. The decorative layer can also consist of real wood or similar materials. If the decorative layer is formed by printed paper, a transparent layer which protects against moisture and / or abrasion, which is typically resinous and has abrasion-resistant particles such as corundum, aluminum oxide or silicon carbide, is usually located above the paper. Below the plate is then usually a so-called Gegenzugpapier which is impregnated by means of resin, or a real wood or other material existing layer, which is intended to prevent warping of the panel attached.
  • If panels are assembled to form a covering, the joints at the top can have recesses with the decor. This happens regularly for visual reasons. Such a recess is in the DE 381 9245 A1 disclosed. But there are also technical advantages, such as to facilitate the lateral connection of two panels by pivoting, such as the WO 01/96688 A1 refer to is. By lateral milling coupling means such as tongue and groove for vertical positive connection and further locking means for horizontal positive connection and the recess are created. In contrast to the adjacent surface, the region of the recess is then not protected against moisture and provided with a decoration.
  • To get out of the WO 01/96688 A1 To make known V-joint decorative, this is printed separately after milling and preferably with a waterproof material, at the same time to ensure protection against moisture. The abutting edges and transitions are relatively sensitive to the ingress of water or moisture.
  • The publication DE 203 00 306 U1 relates to a floor panel with a support plate of a wood material, at least one arranged on the top of the support plate coating and arranged with the longitudinal edges and at the transverse edges connecting means for connecting the floor panel with other similar floor panels. In one embodiment, joints are provided which are provided with an additional coating.
  • The publication WO 03 012224 A1 discloses floor panels for horizontally mechanically connecting floor panels by connecting means having corresponding active joining surfaces, wherein at least one of the active joining surfaces of the bonding means is made of elastically deformable material different from the material of the base body of the floor panel.
  • The publication WO 97 47 834 describes a floor covering consisting of floor panels with coupling parts, in particular in the form of a tongue and joint opening, which can prevent a mutual drifting of two coupled floor panels by integrated mechanical locking means.
  • The publication WO 01 96688 A1 relates to a floor covering consisting of hard panels, which are locked together by coupling means. In one embodiment, a hard panel of flooring at the top has a chamfer provided with a decorative layer which is preferably moisture resistant.
  • The object of the invention is to provide panels of the aforementioned type with a moisture protection at the joints to protect the visible surface from damage.
  • The object is achieved by panels with the features of claim 1. Advantageous embodiments emerge from the dependent claims.
  • The from the WO 01/96688 A1 Known recesses which border on the surface, according to the invention not only printed, but painted over the entire surface or dyed or applied an elastic material. The color or the elastic material such as rubber or silicone is uniformly applied over the entire surface. The painting, coloring or layer of elastic material extends into the interior of a joint, so that it is ensured that in two interconnected panels not only edges of a printed decoration border each other. Instead, paint or color layers are pressed over the entire surface and thus reliably against each other. The particularly critical area at the bottom of a recess at the boundary between two panels is thus better protected against moisture compared to the prior art.
  • Moisture-repellent lacquer or paint layers, and above all layers of elastic material, are applied so thickly that two of these layers are pressed against each other in the connected state of two panels and thus ensure a tight contact between two panels. When sticking a tape or printing according to the prior art may happen that not band against tape or printed ink is pressed against printed ink, but that instead underlying areas of the panels are particularly close to each other. In this way, penetrating moisture can damage a visible area of the panels from the surface. According to the invention, however, it is ensured that paint layers or layers of elastic material against each other in the critical transition region from one panel to another pressed against each other and thus improved protect against moisture.
  • The layer thickness is advantageously at least 1/10 millimeter, advantageously at several 1/10 millimeters. If the material behaves flexibly and / or elastically, several 1/10 millimeters are to be preferred as the layer thickness. Preferably, the layer thickness is then at least 3/10 millimeters, more preferably at least 5/10 millimeters.
  • The moisture-repellent layer is applied in particular following a lateral milling of coupling elements. Thus, the moisture-repellent layer can not be subsequently damaged by processing steps.
  • Reference to the following embodiments, the invention is explained in detail. Show it
  • Fig. 1:
    Panels with V-joint and a layer of elastic material;
    Fig. 2:
    according to interconnected panels FIG. 1 ;
    3:
    Panels with V-joint and a lacquer coating;
    4:
    Panels with V-joint, which can be connected by lowering.
  • The figures show panels 1 and 2 which by means of a groove 3 and a spring 4 vertically, that is perpendicular to the surface of the lining can be positively connected to each other. Further locking elements 7 and 8 serve the positive connection of two panels in the horizontal direction parallel to the surface of the covering. The panels have recesses 5, which are in the assembled state of two panels in section V-shaped. Decorative, however, may be other deviating from a V-shape cross sections. Thus, such recesses are popular, which are arched outwards.
  • The groove 3 may have an advanced lip 6 in order to provide locking elements 7 and 8 outside the groove can, as the FIGS. 1 and 2 clarify. Advantageously, more space is available. This can be used to connect panels particularly firmly to each other form-fitting manner can. The fixed connection is in particular when two panels can be connected by pivoting, like the FIGS. 1 and 2 show, but not by moving the panels in a plane.
  • With the in FIG. 3 In the embodiment shown, panels can be connected by moving in a plane. This facilitates handling, for example, when narrow sides of panels have to be connected to one another. Also, the blend is low. The manufacturing costs of in FIG. 3 Embodiment with the same long legs of the groove 3 are therefore smaller.
  • On the visible side of the covering, the panels are provided with a decorative layer 9. The decor can be created by printed paper or wood. Below the panels 1 and 2 there is generally a serving as a counter-layer, which is similar to the structure of the decorative layer, so as to avoid distortion.
  • According to the invention, the walls of the recess are provided with a moisture-repellent lacquer and / or color layer or a moisture-repellent layer of flexible, elastic material 10 such as silicone. This layer is preferably applied after the milling of the coupling elements 3, 4, 7, 8 and the recesses 5. The layer 10 is sufficiently thick so that the layers are firmly pressed against each other at the base 11 of the recess. So a particularly good moisture protection is brought about in this critical transition region. It is then sufficient to provide only the walls of the recess with the protective layer 10. This is especially true when the layer consists of flexible and / or elastic material. By full-surface and uniformly applied, it is ensured that the recess is fully protected.
  • In the in the FIGS. 1 and 2 shown embodiment of the panels facilitate the recesses 5 advantageously the connection by pivoting.
  • In the embodiment according to FIG. 3 The moisture-repellent layer 10 does not only cover the walls of the recess 5, but extends into the interior of the joint. Will the in FIG. 3 shown panels 1 and 2 connected to each other, so not only edges of the layer 10 abut each other, which are not sufficiently close to each other with insufficient layer thickness. Instead, the layers 10 adjoin one another within the joint 10 in a planar manner. Even if moisture now penetrates into the interior of the joint, so moisture reaches the transition between a panel 1 or 2 and the layer 10 only within the joint. This transition from the layer 10 to the area behind the panel is not visible from the surface. So even if moisture should penetrate into the interior of the joint despite pressed surfaces against each other, a comparatively moisture-sensitive area is affected, which is not visible from the outside. Thus, the covering retains its most important function, namely to look decorative from the surface.
  • In addition to those in the FIGS. 1 to 3 In embodiments shown, there are panels that can be connected to each other by lowering without glue. By this is meant that a panel 2 is held parallel to a panel 1, as in FIG FIG. 4 will be shown. Are there coupling elements suitable for each other and the panel 2 is maintained while maintaining the lowered parallel position along the arrow 12 so lock the coupling elements finally into each other. The two panels 1 and 2 are then positively connected to each other. Among other things, the DE 202 06 751.3 such panels.
  • In this type of connection is particularly critical that the surface is damaged by lowering, in particular in the region of the joint. It is therefore particularly advantageous in such embodiments to provide recesses 5 in the joint adjacent to the surface with the decor. Thus, damage to the rectangular, particularly vulnerable edges, as provided in the prior art, are avoided. If a varnish or a paint is applied, a damage that has nevertheless occurred can easily be repaired, especially since the recess is typically poorly illuminated and therefore damage or subsequent repairs are scarcely noticeable anyway. If an elastic layer is applied, this critical area is protected against accidental impacts anyway.
  • In the FIG. 4 known embodiment is up on the recesses of the DE 202 06 751.3 known. Here the specifics and advantages of these coupling elements are described in detail. A downwardly directed coupling element 13 of the panel 2 passes through the lowering in a corresponding recess 14 which is present within a projecting lower edge 15 of the panel 1. As a result, the panels 1 and 2 are positively locked parallel to the surface 9 and perpendicular to the common joint. A laterally outwardly projecting spring 16 of the panel 2 finally engages in a corresponding recess 17 of the panel 1 a. Thus, the two panels are perpendicular to the surface of the 9th locked together. Special feature in the embodiment of the FIG. 4 is that the spring 16 projects less far laterally than the surface area located above it. This further improves that damage to the surface can be avoided.
  • It is of particular advantage to provide on the long sides of panels coupling elements which are connected by pivoting together. Such coupling elements are in the FIGS. 1 and 2 disclosed. On the narrow sides coupling elements are then preferably provided, which can be connected to each other by lowering. Thus, three panels can be connected by a pivoting movement particularly stable at the same time and that two panels on the long sides by pivoting and at the same time the panel, which is pivoted, with an adjacent third panel on the narrow sides. The recesses 5 then prevent both on the long and on the narrow sides accidental damage to the joints in the surface area.
