Description

Interior fittings

The innovation concerns an interior fitting element for use in interior fitting, in furniture manufacture or in wall and ceiling cladding, or for facade cladding, consisting of board-like furniture panels or panels, which are connected to adjacent panels in an angular or curved arrangement in the area of an edge via a glued joint.

Known interior fittings of this type were previously connected to one another in an angled or curved arrangement using tongue and groove in a glued joint. With a curved edge guide or when joining two panels at an angle to one another, it was also usual to use additional connecting elements such as screws, clamps, connecting profiles and the like at the edge connection. The disadvantage of these known interior fittings was that when the panels were joined together, the surface was interrupted and that the glued joint was visible from the visible side of the panels. In addition, the use of additional connecting elements in the area of an edge-shaped bend was complex.

The innovation is based on the task of developing an interior fitting element of the type mentioned above in such a way that any desired molding of the interior fitting element can be achieved in a simple and economical manner without there being an interruption in the area of the edge of this molding.

To solve the task, the innovation is characterized by that the board-like planed plate or panel in the area

the edge to be formed has a notch on the back, the depth of which extends at least to the back of the veneer covering the furniture panel.

The essence of the innovation is that now, in order to produce curved or

This makes it possible to fold even very long, large furniture elements so precisely that the thin outer covering does not break when folded over, so that practically any length can be folded. In this way, angled furniture elements can also be produced in lengths of 8-12 m in an economical way. In this way, connecting elements can be omitted in the edge area and, in particular, only the

Innovation a continuous surface course also in the angle or

curved area of the panel. This allows sharp edges or curved sections of the panel to be achieved without separating the furniture elements in these areas. All versions have in common that the

Furniture plate attached notch cut on the front

the covering layer is not damaged and does not break when the element is folded over.

Such a furniture element can be used for wall and ceiling cladding, as well as for the furniture itself. With this innovation, it is now possible to fold the body of a piece of furniture from one piece, without any interruption between the adjacent furniture panels. On the one hand, this saves the corresponding connecting elements and, on the other hand, this piece of furniture takes on a completely new look, because it lacks the sharp edge and the otherwise necessary interruption in the form of a fold or mitre, which otherwise always had to be made in furniture panels.

Another area of application for this innovation is interior construction, not only in the production of panels that can be folded as desired, but also in the production of corresponding hollow beams to replace the usual solid beams.

&idigr;&eegr; The design of the innovation provides that at the end of the notch cut in the area of the back of the veneer, an expansion space in the form of a groove is provided. This groove serves to absorb tension that occurs in the folded arrangement when

Gluing occurs. In the notch cut and in the groove on the back of the veneer

Glue is applied to form an angular element when the furniture panel is folded over. The glue that is filled in sets in the groove, whereby the tensions that arise from the groove directly on the back of the

veneer.

The size of the groove on the back of the covering (plastic laminate or wood veneer) depends on the thickness and type of covering and the type of glue. With wood veneers, high tensions can be expected in the glue area, so that this groove is formed larger than with plastic laminates, for example. Furthermore, filling the groove with glue ensures the necessary stability in the uniform area of the furniture element, which is particularly advantageous in the area of the thin covering on the edge of the furniture.

In a further development of the innovation, it is intended that the notch cut extends into the back of the veneer covering the furniture panel and scratches it. In this case, for example, with a 0.7 mm thick veneer, it is intended to scratch it to a depth of about 2/10 mm from the back. By extending

By guiding the notch cut into the back of the covering layer, the panels can be easily folded over without having to worry about the front of the covering tearing when forming an edge.

Advantageously, the notched cut has projections and serrations in the area of opposite cutting edges in the manner of a self-seeking profile. In addition to the gluing, serrations can also be provided when folding a panel in order to achieve greater stability.

In the development of the innovation, the board-like furniture board or the panel can have several notch cuts on the back and on the front in order to create a zigzag-shaped bent panel wall. By applying the notching and folding technique according to the innovation on both the back and the front of a panel, it is possible to bend a furniture board in a zigzag shape, for example at an angle of 120°, in order to create a stable panel wall with a completely new look from commercially available panels. The unfolding can also be even more pronounced, e.g. in the 90° range or even involve even more acute angles. It is also possible to create not only relatively sharp edges in the area of the bend, but it is also possible to provide curved edges.

According to the innovation, it is also provided that the board-like furniture board or the panel has parallel notch cuts at a distance from one another on the back and further profile-like millings arranged at an angle to one another are provided adjacent to them, whereby the front sides of the millings and the side surfaces of the notch cut support one another when folded over. This opens up another area of application for the present

Innovation has been achieved in that not only panels can be produced, but also hollow beams to replace the well-known solid beams.

Previously, at least 3 elements had to be used to cover ceiling beams, which met at right angles and were then connected to one another using appropriate connecting elements. With this innovation, a continuous furniture panel can be used instead, with two parallel notches arranged at a distance from one another and corresponding millings made on the back and then a U-shaped part folded from this, which then runs without interruptions and serves as a self-supporting ceiling element or building element or is used to cover corresponding ceiling beams.

The board-like furniture board or panel can advantageously have slots on the outside. Additional elements can be inserted into these slots in order to achieve a visually pleasing design.

According to the innovation, it is also provided that the board-like furniture board or panel has a notch cut in the area of the edge to be formed and that a filler rod is arranged in the area of the notch cut. As a result, when the element is folded together, the surfaces of the notch cut no longer collide with one another during gluing, but rather, after the panels have been folded together, a notch cut is created in the area of the fold, into which a filler rod is inserted in order to advantageously achieve stable bends with larger radii.

Advantageously, the filler rod has an arcuate front edge, the radius of which is smaller than the radius of the edge to be formed.

This provides advantageous support for the edge of the panel in the bending area without the radius of the filler bar having to be adapted to the radius of the deformation to be bent.

According to the innovation, sickle-shaped cavities are provided in the side areas in the area of the notch recess between the filler bar and the curved front edge. This reduces tension in the panel, similar to an angular notch cut.

The filler bar can advantageously have profiles or projections and edges that rest on parallel contact surfaces in the area of the notch recess in the manner of a self-seeking profile. This advantageously achieves a stable, arched panel arrangement that, when folded over, will rest on the contact surfaces of the notch recess and anchor itself there on correspondingly profiled surfaces of the filler bar.

The subject matter of the present innovation arises not only from the subject matter of the individual protection claims, but also from the combination of the individual protection claims with one another.

All information and features disclosed in the documents - including the summary, in particular the spatial configuration shown in the drawings, are claimed as essential to the invention insofar as they are new compared to the prior art, individually or in combination.

In the following, the innovation is explained using several implementation methods

Fig. 9&iacgr;

The perspective representation of a ceiling made of hollow beams according to the

Figs. 5 and 6.

In Fig. 1, a panel 1 is shown which is to be formed into an angle in the manner described. For this purpose, the panel 1 consists of a continuous plate 2, whereby this plate can consist of a chipboard, a blockboard or a strip board and the visible side of this plate is covered with a corresponding veneer 3, which is connected to this plate in a known manner using an adhesive process. The veneer 3 can consist of a plastic veneer or real wood. For the plastic veneers or plastic coverings, thermosets and thermoplastics are preferably used.

The panel 1 with the plate 2 and the veneer 3 attached thereto also has grooves 7 on the front side, with which these panels 1 are connected to one another to form angled elements in a manner known per se via corresponding springs 35 (see Figure 4).

The notch cut 4 on the back of the panel 2 is funnel-shaped in the unfolded state and has two cutting edges 9 that run conically towards one another and form an angle 5 with respect to one another, whereby the angle 5 depends on the connecting angle 12 required later between the folded panels. The prerequisite is that in the folded state the cutting edges 9 run approximately parallel to one another.

However, the cut edges could still diverge in a conical manner even when folded.

It is also possible that in the folded state, which is shown in Figure 2, the cutting edges 9 interlock with each other, i.e. one cutting edge engages with projections in corresponding recesses of the opposite cutting edge. This is referred to as a self-seeking profile and is intended in the present

Innovation should also be protected.

Another essential feature of the invention is that the cut edges 9 do not extend at an acute angle to the back of the veneer 3, but that a groove 8 is present approximately in the range of a few tenths of a mm, which has lateral boundary walls 37 according to Fig. 3, the boundary walls forming a groove space 8 which is filled with an adhesive 10 to produce the fold of the panel.

The purpose of this groove 8 is, among other things, to absorb the excess adhesive 10, which, if this groove 8 were not present, would otherwise leak through the veneer 3 towards the front and would destroy this edge in the area of the edge 6.

In the element now folded in Figure 2, it is important that any angle 12 of folding can be achieved depending on the angle 5 of the notch cut 4.

The enlarged view in Figure 3 shows that there is no sharp Edge 6 in the area of the veneer 3, but that the edge

forms a radius 11 in order to avoid any breakage of the edge in this area.

Using the technique described, it is therefore possible to make notched cuts 4 of any length and to fold furniture elements of any length, which was previously not possible in a rational manner.

Figure 4 shows, for example, an embodiment where a wall or cover panel consists of individual panels in a zigzag shape, whereby each panel 1 is folded and has a notch cut 4 in its area. The panels are connected in a manner known per se via a spring 35, but in this embodiment the spring has a phase 36, so that with this phase 36 of the phase 35 it is possible to insert this spring into the abutting end faces and into the corresponding grooves of the panels 1.

The spring 35 can be visible here, or in another embodiment be designed so that the end faces directly meet one another and the spring is then not visible.

This embodiment clearly shows the main advantage of the present invention, because it is now possible for the first time to design such wall and ceiling coverings with zigzag-shaped panels, which was not possible before. The fastening of such zigzag-shaped panels is carried out in a known manner by shooting clamps through the groove 7 into the supporting material of the wall or ceiling behind it, which then holds the panels 1 to the fastening surface. Fastening can also be carried out using fastening clamps.

Another significant advantage of the described angular design of the panels 1 is that there is now a continuous glue joint in the area of the notch cut 4, consisting of the adhesive 10 in the groove 8 according to Fig. 3, which gives this element an inherent rigidity that means that this element needs to be supported less on the corresponding fastening surfaces.

Another significant advantage of the zigzag-shaped panels described is the improved acoustics, because these surfaces at an angle to each other provide better sound refraction.

Figure 5 shows a further embodiment, where in conjunction with Figure 6 it is shown how a beam 13 is produced by folding in the direction of arrow 18. This is based on a furniture panel 38, which is folded into a U-shaped profiled part according to Figure 6.

For the sake of simplicity, only a single folding point is described here, because the adjacent folding point in the area of the other U-leg is designed in the same way.

In the panel 2, two angled profiles 16, 17 are worked out with the help of notched cuts 14, whereby it is important that at the base of each profile 16, 17 in the direction of the veneer 3 there is again a groove 8 which corresponds in its design approximately to that of Figure 3.

For the sake of simplicity, this groove is not shown in detail in Figures 5 and 6.

When making the notched cuts 14, it is only necessary to ensure that the two elements are folded perpendicular to each other so that support surfaces are created for each other.

It is also important that the triangular profiling 17 is arranged in the edge area 19, 20 in order to ensure a smooth transition in the edge area. It is also essential that this triangular profiling is fixed with its side surfaces to the approximately square or rectangular profiling 16.

- 15 -

and that in this area 19, 20, where the notched cuts 14 are made, the said grooves 8 are present, which are then filled with glue during folding or before folding.

It is also essential that the front side 39 of one plate 2 is supported on the associated contact surface 40 of the profiling 16, so that the two elements at an angle to each other have sufficient support for each other.

Figure 6 then shows that a U-shaped hollow beam of any length can be efficiently manufactured from such a furniture element, which was previously flat, and it is not shown that with this folding technique described, even completely closed beams can be manufactured, whereby such a folding technique can be manufactured without joints on three different edges, while the fourth edge has a joint to close the element.

In this embodiment, it is again important that the previously described groove 8, which is filled with glue, ensures that this element has sufficient inherent stability, which means that very stable and inherently rigid elements can be produced with relatively thin material thicknesses, which then require fewer suspension points. It is important in these embodiments that the notch cut 14 extends at least to the back of this veneer, but in some cases even extends a few tenths of a millimeter into the veneer. The depth depends on the type and thickness of the veneer.

The application of such notched cuts is carried out either with milling cutters, so that it is a notched milling cut, but it would also be possible to make such notched cuts with appropriate

speaking Hessians.

The milling tools can be used vertically or horizontally.

Figure 6 shows additional corresponding connecting elements, whereby it is shown as an example that each U-leg of this hollow beam 13 has receiving slots 22 into which a corresponding wall connection part (not shown in detail) can be inserted. The receiving slots 22 consist of two slots 23 arranged at an angle to one another, which correspond to the profile of the wall connection part, whereby this wall connection part then has this profile shape of the entire receiving slot 22 and Figure 6 shows that the depth of the receiving slot 22 extends almost over the entire thickness of the plate 2.

Figure 7 shows the side view of such a part in the direction of arrow 7. Figure 8 shows the technical application of the hollow beam according to Figures 5 and 6, where it can be seen that a multiple beams 13 of any length, which are manufactured using the folding process according to the innovation, are attached to a ceiling surface 41. Beams 13 of this type can also be used to cover corresponding supports. However, they can also be designed as self-supporting elements.

This hollow beam construction is particularly advantageous for this type of fastening, because Figure 8 shows that it is easy to fasten hollow beams of this type to a ceiling surface. To do this, it is intended that strips 43 are first attached to the ceiling surface in parallel and at a distance from one another, and the beams 13 with their recesses 42 are then simply pushed onto these strips and connected to the strip in a concealed manner.

be bound.

This is a particularly simple fastening system that uses folding technology.

Figure 9 shows a further embodiment of the present invention, wherein it can be seen that a filler rod is used to produce radii in the transition area between two panels 2, which prevents the relatively large radius of the veneer from collapsing or collapsing.

The following construction is planned for this purpose:

The two plates 2 have a notch cut 24 in the edge area, whereby the notch cut 24 initially consists of two cut edges 25 lying parallel to one another in the folded state. The two cut edges 25 run into a notch recess 26, which corresponds in its function to the previously described groove 8.

The notch recess 26 has contact surfaces 34, wherein these contact surfaces 34 merge into arcuate surfaces 44 in the front region.

The entire notch recess 26 is now essentially filled by a filler rod 28, whereby it is essential that the filler rod 28 has an arcuate front edge 29, the radius of which is selected to be smaller than the radius of the lining arch 31. In the area 32, which makes up about 1/3 of the total arch length, the two radii, i.e. the radius in the area of the front edge of the filling level 28 and the radius of the lining arch inner edge 31, match, so that here in the area 32 a support is created which ensures that the lining arch does not collapse over its entire length

and is optimally supported.

It is also important that the radii outside the area 32 deviate from one another, whereby crescent-shaped cavities 30 are formed, which are filled with glue before or when the filler rod 28 is inserted and which, due to their crescent shape, ensure that the bending stresses are smoothly transferred to the filler rod 28 and to the covering sheet 31.

It is also important that the filler rod 28 has profiles, such as projections 27 that rest on corresponding parallel surfaces of the notch recess 26. Furthermore, edges 33 that work together with corresponding contact surfaces 34 of the notch recess 26, whereby it is a self-seeking profile overall, i.e. the filler rod 28 deforms when the two plates 2 are folded over so that it rests snugly and snugly on the associated profiles of the notch recess and interlocks with these profiles. This is therefore a self-seeking support step.
