Description

• einer Grundplatte, die vorzugsweise als Holzspan- oder MDF-Platte ausgebildet ist,
• einem auf die Grundplatte aufgebrachten, vorzugsweise mehrere Schichten aufweisenden, polymeren Laminat,
• wobei zumindest die oberste, von der Grundplatte abgewandte Schicht des Laminats transparent oder transluzent ausgebildet ist.

The invention relates to a furniture plate with

• a base plate, which is preferably designed as a chipboard or MDF board,
• a polymer laminate applied to the base plate, preferably comprising several layers,
• wherein at least the top, facing away from the base plate layer of the laminate is transparent or translucent.

A furniture panel with the features described above is from the DE 20 2011 004 030 U1 known. With the help of the top, facing away from the base plate layer of the laminate in transparent or translucent optics, a glass optics can be produced, which offers cost advantages over real glass. A disadvantage of real glass fronts is further that surface treatments are difficult to carry out due to the sensitive material glass. Basically, there is an ever-increasing need in the furniture industry for an individual optical design of the furniture panels with the greatest possible flexibility and at the same time acceptable costs. Here, furniture panels with real glass fronts reach their limits.

Against this background, the invention has for its object to provide a furniture panel with the features described above, which allows a simple and cost-effective way a visual appreciation of the furniture panel.

Based on a furniture panel with the features described above, this object is achieved in that the polymeric laminate has at least one spaced from the edges of the base plate milled, which serves for the optical design of the furniture panel. According to the invention it has been recognized that a generic Furniture panel can be visually upgraded in a very simple manner with the help of a corresponding milled into the surface of the polymeric layer composite, for example by this structure surfaces of real wood furniture fronts are modeled. Thus, for example, by means of the teaching according to the invention the haptics and, correspondingly, the look of a real wood furniture front can be emulated, which is composed of a number of individual parts like a frame. The milling can be made with a, eg CNC-controlled, milling machine or in a so-called wood machining center (BAZ).

Conveniently, the milled recess runs parallel to at least one edge of the base plate, this edge preferably forming a straight line. In the context of the invention, it is particularly the case that a plurality of linearly extending millings are provided which run parallel and / or perpendicular to one another. In particular, the milled slots can form a grid pattern or T-shaped connection points. Expediently, the individual surfaces of the furniture panel formed and limited by the recesses have an edge length of at least 1 cm, preferably at least 2 cm. By means of the measures described above, it is possible to replicate the look and feel of high-quality furniture fronts, which are composed of several individual parts and, for example, frame-like structures. In the context of the invention, it is in this case in particular that two along the furniture plate continuous linear milling are provided, which are supplemented by two perpendicular thereto linear milled cuts that end at the connection points with the continuous milled slots, so that the T-shaped connection points described above arise. Such an embodiment is eg in the Fig. 6 shown. Generally, it is within the scope of the invention that - regardless of their shape - several milled cuts are provided which may be spaced apart.

In the context of the invention, however, it is also possible that the milled recess has a curvature. For example, the milling can describe a circle. The very easy machinability of the polymer layer composite also makes it possible that even complex engravings are produced by means of milling, for example by the milled cut represents a lettering. Also, the milled recess may for example have a waveform, or it may be provided a plurality of, for example, mutually parallel, wave-shaped milled grooves. Overall, the teaching of the invention allows a very flexible processing of generic furniture panels, which specifically according to customer requirements can be designed individually, because the design variety are practically no limits.

The milled recess may have a V-shaped, U-shaped or trapezoidal cross-section. In the context of the invention, it is further provided that the milled recess has a groove-shaped cross section with an undercut. In particular, in this case, the milling in addition to their optical function additionally also fulfill a technical function, for example in the form of a groove-shaped holder for the furniture board to be attached objects. This can be a holder for a kitchen roll, pots, cutlery or the like, for example, in kitchen fronts.

The milled recess may have a depth of 0.05 to 7 mm, for example 0.3 to 2 mm or alternatively 2 to 7 mm. If the milling only has an optical / design function, lower milling depths are expedient, for example 0.05 to 0.2 mm for engraving or 0.5 to 1.5 mm for structural designs. By contrast, in the case of a milling having a technical function, significantly greater depths may be expedient, for example at least 3 mm, in particular at least 4 mm.

In the context of the invention, it is the case that a lacquer layer is applied to the outer surface of the polymeric laminate, which is used to protect the polymeric laminate and is generally transparent. As a result, the scratch resistance and / or the UV stability of the furniture panel surface can be significantly improved.

The polymeric laminate may have a total thickness of 0.5 to 5 mm, preferably 1 to 3 mm. Conveniently, the uppermost layer of the polymeric laminate of PMMA (polymethyl methacrylate) and / or PC (polycarbonate) and / or SAN (styrene / acrylonitrile); Alternatively, the uppermost layer may also consist of a polyolefin. This top layer has expediently a thickness of 1 to 3 mm, for example 1.5 to 2.5 mm. The uppermost layer is expediently transparent. Underneath a colored layer can be provided, which also has a certain translucency. In principle, the same materials are considered for this layer as for the topmost layer. The thickness of this layer is suitably 0.1 to 0.3 mm. Below this is expediently a colored layer of ABS (acrylonitrile / butadiene / styrene) and / or SAN, this layer expediently having a thickness of 0.2 to 0.4 mm. This layer may be the lowermost layer of the polymeric laminate and then expediently produces the compound of the polymeric multilayer laminate with the base plate. In general, the multilayered polymeric laminate can be produced by bonding the individual layers, for example by means of a calendering process or else by coextrusion of the layers. However, other methods for producing the multilayer laminate are also conceivable. In principle within the scope of the invention, however, it is also the case that the laminate consists only of the uppermost layer and is accordingly designed in a single-layered manner. Likewise, a colored (possibly also white or black), preferably opaque covering, lacquer layer may be provided between laminate and base plate, which is for example painted on the underside of the laminate.

In the context of the invention, it is provided on the side facing away from the polymeric laminate side of the base plate, a so-called. Gegenzug is provided which prevents distortion of the furniture panel. This counter-reaction may also be multi-layered, e.g. with a core layer of a recycled material and layers applied on both sides of the core layer; wherein the two edge layers of the backing, for example, of a styrene copolymer, e.g. ABS, or PMMA and either both consist of the same material (eg ABS inner layer / ABS outer layer or PMMA inner layer / PMMA outer layer) or of different materials (eg ABS inner layer / PMMA outer layer or PMMA inner layer / ABS outer layer).

The milled recess may end normal to the panel within the laminate, preferably within the topmost laminate layer. This is particularly useful if the milled only fulfills an optical / designerische function. In the context of the invention, however, it is also the case that, as seen normal to the plane of the plate, the milling ends inside the baseplate, that is, the laminate is completely severed by the milled-in position. This too can result in interesting optical effects. However, this deep milling geometry is particularly advantageous also for the cases in which the milling in addition to its optical function also has a technical function, e.g. in the form of a retaining rail, should own.

Conveniently, the base plate and the polymeric laminate are provided at the edge with at least one edge band, which covers both the base plate and the laminate at the edge. Accordingly, a border of the composite of base plate and laminate is achieved by the edge band, so that the furniture plate edges a have optically perfect appearance. In this context, it may be expedient that the edge band is formed partially transparent, namely, in particular in the overlapping region of the transparent or translucent layer or layers of the polymeric laminate is transparent. Thus, the edge of the desired real glass optics can be realized by means of the polymeric multilayer composite. Conveniently, therefore, the edge band consists of a polymeric material which can be easily processed. The edge-side attachment of the edge band to the base plate or the polymeric laminate can be done via a, preferably transparent, laser functional layer with which the edge band is provided. By means of known laser technology, the edge band can be attached to the edge of the furniture panel. Such a method is for example in the DE 20 2007 011 911 U1 described.

The teaching of the invention finds particular applications in the kitchen furniture industry, but is also generally attractive for the office furniture industry. Basically, however, the use of the teaching of the invention in the furniture sector is not limited.

a further embodiments of the invention in one of the Fig. 2 corresponding representation

Fig. 1 shows a basic structure of a furniture panel in an exploded view, the furniture panel is not provided here with a milled. The furniture panel has a base plate 1, which is formed in Ausführungsbeipiel as wood chip or MDF board. On this base plate 1, a polymeric laminate 2 is applied, which has three co-extruded layers 3, 4, 5. The uppermost layer 3 of the polymeric laminate 2 in the exemplary embodiment consists of a transparent PMMA with a layer thickness of 2 mm. Below this, a colored PMMA layer with a thickness of 0.2 mm is arranged as the middle layer 4. The lowermost layer 5 of the laminate forms a 0.3 mm thick, colored layer of ABS or SAN. Since the central PMMA layer 4 has a certain translucency, the visual impression of the polymeric laminate 2 is also determined by the lowermost layer 5. The lowermost layer 5 produces the composite of polymeric laminate 2 with the base plate 1, the laminate 2 being adhesively bonded to the base plate 1, for example, with an adhesive, not shown. It can also be seen that a lacquer layer 6 which increases the UV stability is applied to the uppermost layer 3 of the polymeric laminate 2.

In the Fig. 1 It can also be seen that the base plate 1 has on its side facing away from the polymer laminate 2 a so-called. Gegenueback 7, which is also constructed of a plurality of layers. This counter-pull 7 serves to ensure that the base plate 1 does not warp unilaterally during application of the polymeric laminate 2 or in later use. The counter-train 7, in the exemplary embodiment, has a three-layered construction. It is provided a core layer 8 of a recycled material, which has a thickness of 1 -2 mm, for example, 1.5 mm. Layers 9, 9 'with a thickness of 0.1 to 1 mm, for example 0.5 mm, are applied to both sides. The base plate 1 facing inner layer 9 of the counter-train 7 is made of ABS, while the outer layer 9 'of the counter-train consists of PMMA. The counter-pull 7 is attached to the back of the base plate 1 to ensure the previously described permanent freedom from distortion of the furniture panel. The narrow sides of the furniture panel are covered with an edge band 10. This edge band 10 has two areas. In the region of the overlap of the base plate 1, the edge band 10 has a through-colored portion 11. By contrast, in the region of the covering of the polymer laminate 2, the edge band 10 has a section 12 consisting of a transparent or translucent material, eg a transparent PMMA. The connection between the edge band 10 and the base plate 1 or laminate 2 is made transparent by an edge band 10 Laser functional layer 13 produced. The base plate 1 may have a thickness of 10 to 20 mm, in the embodiment, the thickness is 14 mm. The polymeric Glass laminate 2 has a total thickness of 2.5 mm, as described above. On the polymeric laminate, the UV protective lacquer layer 6 is applied, which has a thickness of 10 to 25 microns. The lacquer layer 6 also serves to increase the scratch resistance.

The Fig. 2 to 5 each show a detail of a cross section through in the Fig.1 shown, now provided according to the invention with a milled recess 14 furniture plate in different embodiments, wherein for simplicity in the drawings 2 to 5 of the counter-pull 7 is not shown. It can be seen that the polymeric laminate 2 has at least one milling cut-off 14 which is subject to the edges 15 of the base plate 1 and serves for the optical design of the furniture panel. In the Fig. 2 are two with an edge length L spaced V-shaped milled recesses 14 can be seen, which have a depth t and end normal to the plate plane within the uppermost laminate layer 3 ends.

In the embodiment according to the Fig. 3 In contrast, the milled recess 14 has a trapezoidal cross-section and a greater depth t, so that the milled recess 14 terminates within the base plate 1 as seen normal to the plane of the plate. Accordingly, the laminate 2 is completely severed by the milled recess 14 in this area.

In Fig. 4 the milled recess 14 has a groove-shaped cross section with an undercut. This is also the case Fig. 5 the case, wherein the milled recess 14 here forms a so-called dovetail guide. at Fig. 4 on the other hand, the recess 16 forming the undercut has a rectangular cross-section. In the embodiments according to the 4 and 5 takes the milled recess 14 in addition a technical function, for example, it is used for mounting objects on the furniture panel, eg holders for a kitchen roll (s. Fig. 7 ), Crockery, cutlery or the like on kitchen fronts. It is also conceivable, however, the mounting of brackets for garments etc.

In the Fig. 6 to 9 Inventively processed furniture panels are shown. In these furniture panels each have a plurality of linear milled slots 14, 14 'are provided which are parallel and / or perpendicular to each other. According to the embodiment Fig. 6 are two along the furniture plate continuous, parallel aligned linear milled recesses 14 are provided, which are complemented by two perpendicular thereto linear milled recesses 14 ', which at the connection points with the continuous Milling 14 ends. Accordingly, the milled channels 14, 14 'here form T-shaped connection points 17. In this way, a typical composed of several parts high quality frame geometry of a furniture front can be imitated, both designerisch and haptic. The Fig. 6 shows a trained as a door furniture panel with a handle 18. In the embodiment according to Fig. 7 the linear milled cuts 14 run parallel to one another. In addition to its optical function, the uppermost milled recess 14 also has a technical function in that it forms a retaining rail for the holder 19 of a kitchen roll 20 in the furniture panel. According to the embodiment Fig. 8 the milled grooves 14 form a grid pattern and according to Fig. 9 are provided several milled cuts 14, which are each formed curved. In the embodiment, the milled grooves 14 each describe a circle.

In the exemplary embodiments, the individual surfaces 21 of the furniture panel formed and bounded by the cutouts 14 have an edge length L of at least 1 cm, preferably at least 2 cm. The edge length L described above is also in the Fig. 2 shown. Basically, the Fig. 2 or 3 For example, a section of a vertical or horizontal cross section through the furniture panel in Fig. 8 represent while the FIGS. 4 or 5 For example, a cross section through the holder 19 receiving milled recess 14 in Fig. 7 demonstrate. The milled cuts 14 can be designed to have different depths. In the embodiment according to the Fig. 2 the depth t is comparatively small and here is 1 mm. In the embodiment according to the Figure 3 on the other hand, the 2.5 mm thick polymeric laminate 2 is completely severed by the milled recess 14, which here has a depth t of 3 mm. In the embodiments according to the FIGS. 4 and 5 are the cutouts 14 even deeper, eg t = 5 or 6 mm.

According to the embodiment FIG. 10 the laminate 2 consists only of a topmost transparent layer 3 of PMMA. This layer 3 is coated on the underside with a opaque opaque, colored lacquer layer 22.
