Abstract

A furniture building element includes a veneer panel which is provided with two parallel VEE-grooves (5,6), on the same side of the panel. The grooves which cut through one outer (3) and the centre layer (4) allow the panel to be folded along these grooves. The trough shaped profile so obtained provides the outer mould, which becomes an integral part of the element, for expanded foam. Thus various profiles, made from veneer panels, can be filled with foam.

Description

Component for building and furniture needs

The invention relates to components for building and furniture needs.

Components for building needs, which have a substantially beam-shaped Have a cross-section and have an outer skin and a foamed plastic core, are already known per se. These are bars made of a foamed Plastic material used in interior design for the rustic design of rooms are used and received in the commercial sector and in the private residential sector Ceilings are attached.

For this purpose, plastic material is foamed into appropriate forms, whereby an outer skin and a core are formed. Such bars occur on the Instead of expensive solid wooden beams and in the place of plywood panels imitation wooden beams, which have solid wood strips in the area of the bevels, which are labor-intensive to work on.

It is also known in chipboard coated with a veneer V-shaped recesses, which extend to the veneer, mill these recesses to glue and bend the panels so that the legs of the recesses be glued together. In this way are z. B. Door frames manufactured. Because the angle connections are made via the legs that are glued together are manufactured with a force fit, the chipboard must have a minimum thickness, which is about 16 mm.

It is also known in this way components for furniture needs and to produce box furniture directly, due to the thickness of the chipboard have considerable weight.

In general, the known components are for furniture needs essentially chipboard, which in a simple design with a printed plastic film, are provided with a wood veneer in a better design. You will mainly for the production of modular furniture such. B. used by closets and bookcases. There is also a problem in that great weight of such furniture and another problem that the edges with Edging are to be provided, which has not yet been solved satisfactorily.

The invention is based on the object of a component for building needs to create, which is also a substantially bar-shaped or a substantially plate-shaped cross-section and an outer skin and a foamed plastic core has great torsional rigidity and light weight, and therefore universal not only for beams for subsequent rustic Interior fittings can be used, but also for the production of roller shutter boxes, Door frames, door leaves, paneling panels and partition walls are used. Here you can in the production of e.g. B.

of the components for door leaves, the fittings are foamed at the same time will.

The invention is also based on the object of a component for the furniture industry and clay furniture according to the same structure that at the place of veneered chipboard as well as the place of the blockboard occurs and also has great torsional rigidity and low weight and because of its damping behavior for the production of clay furniture such as B. loudspeaker boxes to be built into furniture walls, as well as for loudspeaker housings and chassis for turntables. Fasteners can also be used during manufacture are provided so that under components for the furniture industry and furniture needs also cabinet parts, doors, shelf parts, tabletops and in general also those Furniture to be produced from these components is to be understood.

This object is achieved according to the invention in that the outer skin consists of a wood veneer board, the wood veneer board on its angled from the Edges facing away from the side running in the direction of the angled shrouds, essentially Has V-shaped recesses, the substantially V-shaped recesses up to the area of the face veneer and the angled wood veneer board for the foamed-in Plastic core forms a permanent formwork. Wood veneer panels generally exist made of two face veneers, between which another veneer is arranged. For a high-quality face veneer is used on the side facing the viewer. To According to the invention, the V-shaped ones extend into the area of this high-quality face veneer Recesses. In a further embodiment of the invention, the V-shaped recesses are and angled edges arranged on both sides of the wood veneer board d. H., that the wood veneer plate z. B. can be angled zigzag. Generally Wood veneer panels can also be used, which have a multilayer intermediate veneer to have.

According to the invention, the angling of the edges by the essentially V-shaped recesses given included angle. The inventive Bending a wood veneer is only possible as far as the two legs of one substantially V-shaped recess come to bear against each other. It is so It is easily possible to achieve a right-angled folding by beforehand Attempts to determine the optimal angle, as well as by several closely parallel to each other running recesses to form a bevel or rounded edge. During the Foaming of the correspondingly angled wood veneer board results in a intimate interlocking between the hardening Plastic core and the porous surface of the wood veneer, this intimate interlocking through the building up pressure is still encouraged. This way those will be in the wood veneer board stresses built up during the folding along the V-shaped recesses the pressure of the foaming plastic material is compensated or opposite Stresses generated, which result in the high torsional rigidity.

In yet another embodiment of the invention, the legs stand of the V-shaped recesses against each other. This ensures that when Folding the wood veneer board and pressing the legs against each other Avoid tearing of the veneer due to the pressure that builds up during foaming will.

This is of particular importance when the plastic core should be highly compressed in order to achieve a high level of sound insulation in wall panels. The usual wood veneer panels up to a millimeter thick are generally used.

According to the invention, the wood veneer board can be angled so that it forms an outer skin of U-shaped cross-section, with the end faces of the Component from the front edges of the wood veneer board that run in one plane and the end faces of the plastic core are formed. The U-shaped cross-section can be chosen so that either a bar-shaped or a plate-shaped cross-section of the component is formed. The end sections the thigh of this U-shaped wood veneer can also be angled inwards so that this End sections run parallel to the web connecting the two legs. Through this the result is an edge that can also be seen from very close proximity to a solid wood edge is equivalent to. According to the invention, the dimensioning of the length of the free Leg sections are made so that they have a sufficiently large space to Ensure the introduction of the plastic material for the plastic core. In the same It is possible to use the free front edges of these angled leg sections to stand against each other and the plastic material to be introduced from the bring in an open cross-section, or in the area of the angled against each other pending leg sections to provide openings into which then after the Manufacture of the component a corresponding veneer panel or veneer disk is fitted. This embodiment is used for components for high-quality furniture in question.
