EP3589164B1 - Wall of a furniture body, method for producing such a wall, and furniture body or furniture comprising such a wall - Google Patents

Description

The invention relates to a wall, in particular a side wall, of a furniture body, having a plate-shaped core which is arranged between two laterally applied cover layers, the core having a recess which extends at least along a section of an end face of the wall and accommodating a fitting serves, which leads a movable furniture part. The fitting lies against at least one of the cover layers and is connected to the core and / or at least one of the cover layers. The invention further relates to a method for producing such a wall and a furniture body or a piece of furniture with such a wall.

Furniture, in particular kitchen furniture such as base cabinets or wall cabinets, generally have a furniture body that is open to the front and on which movable furniture parts guided by fittings are mounted. The movably guided furniture parts can be drawers with a drawer front or doors or flaps that can be used individually or in different combinations on a furniture body. The present application relates in particular to the use of doors and flaps as movable furniture parts. In the context of this application, doors and flaps are distinguished on the basis of the orientation of their pivot axis, which runs vertically in the case of doors and horizontally in the case of flaps.

The doors and flaps can be in one piece or consist of several individual parts, such as in the case of a folding flap, in which different parts of the flap move relative to one another in the course of movement.

Door hinges, which are arranged on the side of the pivot axis between the furniture body and the door, are generally used to guide doors. A comparable arrangement of hinges can in principle also be used for flaps. These hinges are then arranged along an upper side edge of the flap. However, it is often desired to open the flaps in a combined pivoting and sliding movement in order, for example in the case of a hanging cabinet, to obtain the greatest possible access to the cabinet interior without the flap having to be pivoted into a horizontal position in which it is from User cannot be reached to close or can only be reached with difficulty. For this reason, special flap fittings have become established that are not arranged along the pivot axis between the furniture body and the flap, but laterally on (usually both) side edges between the flap and the side wall of the furniture body.

Such door hinges or flap fittings for mounting on an inside of the side wall or the side walls of the furniture body are known. However, the fittings inevitably protrude into the interior of the furniture carcass, which on the one hand reduces the usable storage space within the furniture carcass and on the other hand also impairs the structuring of the interior of the furniture carcass. Cleaning of the interior, in particular the inside of the side wall of the furniture body, is also made more difficult by the fitted fittings. Last but not least, a side wall on which no fittings are mounted is desirable for visual reasons.

To assemble door hinges, it is known to mill a pocket into the end face of a side wall, into which the door hinge can be inserted from the front. In this way the inside of the side wall remains free. A hinge suitable for use in such a milled pocket is, for example, from the publication DE 1 559 963 A known.

However, this procedure is only suitable for door hinges with a very small installation depth. This is due to the limited milling depth with which such a pocket can be economically milled into the side wall from the end face in the manufacturing process. The built-in thickness of the door hinge inserted in such a milled pocket is also very limited, since side walls in the furniture area only have a wall thickness of around 16-20 mm (millimeters). During the milling process, a certain minimum wall thickness must remain on the side of the milled pockets, since a wall that is too thin would tear or break during the milling process or would be deformed in such a way that it no longer has a perfect surface.

Even the use of larger and more complex door hinges is not possible in this way. Flap hinges usually have a large installation depth in the range of more than 10 or 15 cm (centimeters), which cannot be achieved by milling from the front side.

From the pamphlet DE 20 2013 003 189 U1 a side wall for a furniture body is known, which consists of sections of different parts. In particular, a rear part facing away from the furniture front is of conventional design, e.g. B. by a coated wooden element. A front part of the side wall is formed by a housing, not described in detail in the cited document, which has an opening at the end into which a fitting can be inserted. The housing is connected to the conventional part of the side wall by means of dowels or screws, for example. Since the housing can be provided with thinner housing walls than is possible with a milling and also allows greater installation depths, this housing can also be used to accommodate larger door hinges or a flap fitting. The surface optics and haptics of the housing will, however, as a rule not exactly correspond to those of the conventional part of the side wall, so that a uniform surface of the side wall cannot be obtained. In addition, a transition between the two housing parts will be visible and possibly also palpable.

Similarly, according to the document DE 10 2015 108 694 A1 provided for a flap of a piece of furniture to arrange a holding arm of a flap fitting including a fluid spring in a housing which forms a front part of a side wall of the piece of furniture. In this case, too, the surface appearance and feel of the housing generally do not correspond exactly to that of the part of the side wall conventionally made from plate material.

The pamphlet WO 2010/130570 A1 describes a piece of furniture in which the side walls are formed in a frame construction. The side wall comprises a profile frame with applied cover layers. The frame construction forms compartments, with a flap fitting being arranged in one of the compartments, which is attached to profiles from which the frame is constructed. In this way, a larger fitting can also be integrated into the side wall. The frame construction makes the production of the side wall complex, among other things because it can neither be manufactured nor reworked with conventional woodworking machines.

The patent document DE102009025822 A1 also discloses a wall for a furniture body in which a fitting is installed.

It is an object of the present invention to provide a wall and a method for producing a wall for a furniture carcass and a piece of furniture or furniture carcass with a wall, the wall also being able to accommodate larger fittings, in particular flap fittings but also door hinges with a greater installation depth, and the wall is characterized by a uniform surface texture on both its outside and its inside and which can be processed with common woodworking machines.

This object is achieved by a wall, by a method for producing a wall and a furniture body or a piece of furniture with a wall the features of the respective independent claim. Advantageous refinements and developments are the subject of the dependent claims.

A wall according to the invention of the type mentioned is characterized in that the fitting has a lever mechanism and, apart from the lever mechanism extended in an open position, is arranged within the wall, the lever mechanism guiding the movable furniture part and, in a closed state of the furniture part, possibly up to on mounting elements for connection to the furniture part is completely retracted into the wall. Furthermore, the core has a reduced thickness along an edge of the recess on at least one side, in such a way that a bung spring pointing towards the recess is formed, which protrudes into the fitting.

A method according to the invention for producing such a wall for a furniture carcass has the following steps. A plate-shaped core is provided into which a recess is made which extends at least along a section of an end face of the core. Two side cover layers are then applied to the core, the recess being milled out of the core with a milling tool from one side surface of the core, with a fitting being inserted into the recess before at least one of the two side cover layers is applied to the core, and wherein the fitting is screwed and / or clamped and / or glued to the core before the at least one of the two lateral cover layers is applied to the core. The result is a wall for a furniture carcass with a permanently integrated fitting, which simplifies the manufacture of the furniture carcass.

The wall according to the invention is thus a composite element made up of a core and cover layers, the recess necessary for receiving the fitting in the core according to the invention being made during the manufacture of the wall before the cover layers are applied. There are no restrictions on the size of the recess, as are the case when the recess for the fitting is made in a wall that has already been provided with cover layers. Thus, large fittings, for example the entire or almost the entire width of the wall, can be used. At the same time, the wall has a preferably one-piece, continuous cover layer on both side surfaces.

The recess is milled out of the core from one of the side surfaces of the core. The fitting is so completely integrated in the furniture body that - unavoidably - only the lever mechanism, and this only when the movable furniture part is open, is visible.

Since the fitting rests against both cover layers and is connected to the core and / or at least one of the cover layers, an installation width is available for the fitting that corresponds at most to the thickness of the core. Fittings with a width of up to about 20 mm can also be used with a furniture wall of the usual thickness.

The fitting preferably has two parallel side plates, between which a gap is formed at least in sections along an edge, into which the bung spring protrudes. The fitting is so to speak placed on the area of smaller thickness of the core, whereby a good connection between core and fitting is given and a smooth transition as possible results, which is not visible from the outside even with relatively thin cover layers. In the overlap area between the fitting and the core, screws or clips can connect the side panels of the fitting to the core.

Heads of the screws or overlapping sections of the clamps are preferably arranged between the side plates and the cover layers, so that these connecting elements are covered by the cover layers and are therefore no longer visible in the composite element. So that they do not show under the cover layers, the heads of the screws or the overlapping sections of the clamps are furthermore preferably countersunk in the side plates.

An alternative type of connection, which is particularly simple in the production process of the wall, is provided by staples, which are issued from the side panels on the fitting and claw into the core in order to connect the side panels to the core. Alternatively or additionally, the fitting can be glued to the core and / or at least one of the two cover layers.

In a further alternative type of connection, which is also particularly simple in the manufacturing process of the wall, connecting elements are formed from the core adjacent to the recess and engage in the fitting. The fitting then has side plates with recesses, the recesses forming opposing contours into which the connecting elements engage. The core and fitting are accordingly placed into one another like pieces of a puzzle and are positively connected to each other. The role of connecting elements and recesses as contour and counter-contour can of course also be interchanged, in such a way that the recess is formed in the core and the engaging connecting element is formed in the fitting.

In a further advantageous embodiment of the wall, the fitting can have two parallel side plates, the spacing of which corresponds to the thickness of the core. It is also possible for the fitting to have an adjustment unit in order to vary a distance between the side plates and thus to be able to compensate for the thickness of the core.

In a further advantageous embodiment of the wall, at least one edge band is applied to at least one of the end faces of the core. In the area of the front end face of the core, the edge band is preferably only applied when the fitting is integrated or inserted, the edge band being arranged at least in sections on the fitting. In this way, for example, the edges of the side panels of the fitting can be covered.

A piece of furniture or furniture body according to the invention has at least one such wall which is produced according to a method described above. The advantages described in connection with the wall or the method result.

In an advantageous embodiment of the furniture or the furniture body, the at least one wall is a side wall and / or an intermediate wall. The fitting can be a flap fitting or a door fitting.

In the context of the application, the wall according to the invention can be arranged on each side of the furniture body, regardless of its orientation. In particular, the wall can be arranged in any orientation within the furniture body, in particular vertically, horizontally or at an angle, for example diagonally in the furniture body.

Fig. 1 shows an isometric view of a wall unit, for example a kitchen, as a first embodiment of a piece of furniture with a (side) wall according to the application.

The upper cabinet comprises a furniture body 10 with a lower shelf 11 and an upper shelf 12 as well as two side walls 13. A rear wall is preferably provided for reasons of stability, among other things, but is not shown in this exemplary embodiment.

The furniture body 10 is open to the front in order to gain access to the interior of the cabinet. A flap arrangement 20 with a one-piece flap 21 is provided in order to be able to close the opening of the furniture body 10. The one-piece flap 21 is pivotably mounted along its upper horizontal side edge. For this purpose, fittings 30 are provided which are connected to the one-piece flap 21 by means of a lever mechanism 31 in the upper region thereof.

The fittings 30 are arranged within the respective side wall 13 (with the exception of the lever mechanism 31 extended in the illustrated open position). In the closed state of the flap 21, the lever mechanism 31 is completely retracted into the side wall 13 except for the assembly elements for connection to the flap 21. The area within the side wall 13 in which the fitting 30 is located is in the Fig.1 indicated by a dashed line.

The side wall 13 is characterized by side surfaces 131 which are ideally in one piece and have a consistently identical surface quality over the entire surface. The surface of the one-piece side faces 131 can produce design effects by means of different patterns, surface properties or different colors. This preferably applies both to an outer one of the side surfaces 131 and to an inner one of the side surfaces 131 facing the interior of the furniture body 10 Lever mechanism 31 of fitting 30 is immersed or from which lever mechanism 31 extends. In the closed state of the flap arrangement 20, the lever mechanism 31 is completely immersed in the opening 133 apart from any fastening means with which it is connected to the one-piece flap 21 here.

According to the application, the side walls 13 are composite elements which, in connection with FIGS. 5ff. are explained in more detail.

In the Figures 2a and 2b Another wall cabinet is shown as an example of a piece of furniture with a side wall according to the application, each in an isometric view.

As with the example of the Fig.1 a one-piece flap 21 is provided as a flap arrangement 20 in order to close a furniture body 10 towards the front. The two Figures 2a and 2b differ in the opening state of the flap arrangement 20. Fig. 2a shows a partially open state of the flap arrangement 20, where to Figure 2b the maximum opening state of the flap arrangement 20 reproduces. In contrast to the embodiment of the Fig.1 In the present case, a lifting and swiveling fitting is provided which enables a combined swiveling and sliding movement of the one-piece flap 21. In the in Figure 2b In the fully open position shown, at least a part of the flap 21 is positioned above the top panel 12 of the furniture body 10. In this way, good access to the interior of the furniture body 10 is achieved without the lower edge of the flap 21, in the area of which a handle 24 is mounted, pivoting up to the level of the top panel 12. In this way, the flap 21 is easily accessible in the open position in order to be able to close it again even with a wall cabinet mounted high up in the room.

As in the embodiment of Fig.1 Here, too, the side walls 13 are designed as composite elements 40 which receive the fitting 30.

In the Figures 3a and 3b Another embodiment of a wall cabinet with furniture body 10 and flap arrangement 20 is shown. Fig. 3a shows the flap assembly 20 in a closed and Figure 3b in an open position.

In this piece of furniture, a two-part flap arrangement 20 is provided which has an upper flap part 22 and a lower flap part 23. Again, the side walls 13 are designed as composite elements which receive a fitting 30. This is coupled with lever works 31 both with the upper flap part 22 and with the lower flap part 23. In addition, additional hinges 25 are provided which couple the upper and lower flap parts 22, 23 with one another in a pivotable manner along their connecting line. Depending on the design of the flap fitting, the hinges can also be omitted.

As in the embodiment of Figures 2a, 2b Here, too, good access to the interior of the furniture body 10 is achieved without the flap arrangement 20 pivoting too far upwards in the open state, which is difficult to reach for the user.

Fig. 4 shows another upper cabinet with furniture body 10 and flap arrangement 20, in which fittings 30 for guiding the flap arrangement 20 in composite elements 40 are arranged. In the example shown, the furniture body 10 has an interior space divided by vertical partitions 14. In the present case, two partition walls 14 are provided which divide the interior space into three sections. In this embodiment, each partition 14 is designed as a composite element 40. However, the arrangement shown can also be implemented with only one partition wall or more than the two partition walls 14 shown.

The flap arrangement 20, comparable to the exemplary embodiment in FIGS. 3a and 3b, is in two parts with an upper flap part 22 and a lower flap part 23. In order to be able to guide the flap arrangement 20 cleanly, fittings 30 are also arranged in the intermediate walls 14 in the present case. Both the side walls 13 and the partition walls 14 are designed as composite elements 40 according to the application.

In all of the illustrated exemplary embodiments, the composite elements are characterized by continuous side surfaces with a surface look and feel that are uniform over the entire surface. In particular, no transition in the area of the edge of the fitting 30 can be seen in the surface.

The basic structure of an example, not according to the invention, of a composite element 40 with which this is achieved is shown in FIG Fig. 5 shown in an exploded isometric drawing. The composite element 40 shown can be used, for example, as a side wall 13 in the exemplary embodiments of FIG Figures 1-4 be used and also as a partition 14 in the embodiment of Fig. 4 .

The composite element 40 has a core 41, for example made from a chipboard or a medium or high density fiberboard (MDF - Medium Density Fiberboard or HDF - High Density Fiberboard). The core 41 has a rectangular oversize of the size that later has the sides or partition wall in the furniture body to be manufactured (see, for example, side wall 13 of the furniture body 10 according to the exemplary embodiments of FIG Figures 1-4 ). Three front sides, one in the Fig. 5 The left end face 411 and a lower or upper end face 412 run straight in accordance with the rectangular allowance.

A large, flat recess 42, which is open towards a fourth end face 413, is made in the core 41. Only in the upper and lower areas of the core 41 is a narrow section of the end face 413 left on this side. In the area in between, the edge of the recess 42 now forms an inwardly offset end face 414 following the contour of the recess 42.

The contour of the recess 42 corresponds to the outer contour of a fitting 30 to be used, here an approximately L-shaped contour. The recess 42 can be made in the core 41, for example, by milling with the symbolically illustrated milling tool 1. Other machining techniques such as drilling in connection with (plunge) saw cuts can also be used to produce the recess 42. It should be noted that machining can be carried out from one of the side surfaces of the core 41. Machining only from the end face 413 is not necessary in the case of the core 41, which is initially present separately. The recess can thus easily assume any depth (viewed from the original end face 413) and is also suitable for receiving fittings 30 with a large installation depth. The lateral machining direction can also generate contours which are not possible by machining only from the end face 413.

After the recess 42 has been made in the core 41, the fitting 30 is inserted into the recess 42 of the core 41 in a first assembly step I and connected to the core 41. Details on possible connections are provided in connection with the Figures 6 ac and 7 to 11 described in more detail.

The fitting 30 and the core 41 preferably have the same thickness, in particular in a range from 15 mm to approximately 20 mm. The core 41 and the Fitting 30 thus form a unit in which fitting 30 is flush with the surface of core 41 on both sides. Furthermore, the front edges of the fitting 30 also run flush with the two remaining sections of the actual end face 413 of the core 41.

The unit consisting of core 41 and fitting 30 is then followed in a second assembly step II, which in turn is indicated by the corresponding arrows in FIG Fig. 5 is indicated, top surfaces 43a, 43b applied to the corresponding sides of the core 41 or the fitting 30, in particular glued or laminated. These cover surfaces 43a, 43b are preferably already provided with a decorative surface. Their thickness is in a range from a few tenths of a millimeter to about 2 or 3 mm. The thickness is dimensioned in such a way that any remaining small edges in the transition area between the core 41 and the fitting 30 are not or not recognizable in the surface of the cover surfaces 43a, 43b.

In a further manufacturing step, not shown here, the remaining end faces 411, 412 and 413 can also be provided with a decorative layer, for example an edge band. This step can optionally also take place before the cover surfaces 43a, 43b are applied and also before the fitting 30 is inserted.

In the manner described, the composite element 40 is created, which in this form directly has a side wall 13 or an intermediate wall 14 of a furniture body 10 as in FIG Figures 1-4 can form shown and already has the fitting 30 for guiding a flap arrangement.

In the Figures 6a-c and 7-11 Different types of fastening of the fitting 30 to the core 41 of the composite element 40 are shown.

Figure 6a shows first in an isometric view a core 41 of a composite element 40 before the insertion of a fitting 30. For the sake of illustration, the core 41 is already shown as a side wall of a furniture body and is already connected to the bottom and top of the furniture body. This illustrates the later installation position of the composite element 40 in a piece of furniture. In principle, an assembly such that a furniture body is partially manufactured before the fitting 30 is connected to the core 41 and before the cover layers 43a, 43b, not shown here, are placed on the inside and outside of the core 41, would also be conceivable. A complete prefabrication of the composite element 40 including the application of the cover layers 43a, 43b, however, is more efficient for production and assembly and is therefore preferred.

Figure 6b shows the area of the end face 414 of the core 41 at the edge of the recess 42 in more detail. At this edge, the core 41 is milled off on both sides adjacent to the end face 414 in such a way that a thinner edge area in the manner of a bung spring 415 is formed. Due to the milling, shoulder surfaces 416 are formed which form a shoulder with respect to the remaining side surfaces of the core 41.

The fitting 30 has two side plates 301 spaced apart from one another, which laterally delimit the fitting 30 and provide the pivot points for the lever mechanism 31. Spacer sleeves or bolts, which connect the side plates 301 to one another and fix them parallel to one another at a defined distance, are preferably arranged between the side plates 301. In alternative configurations of the fitting 30, screw elements can also serve as spacers which offer the possibility of at least slightly varying the distance between the side plates 301 and thereby adapting it to the thickness of the core 41.

At least in the edge area there are neither bolts nor other elements between the side plates 301, so that the fitting 30 with the side plates 301 can be pushed onto the bung spring 415 of the core 41, as shown in FIG Figure 6b is shown by the arrows I. The side plates 301 are preferably spaced apart from one another on the inside to such an extent that they can be pushed onto the bung spring 415 with an accurate fit. The thickness of the side plates 301 more preferably corresponds to the depth of the shoulder between the shoulder surfaces 416 and the remaining surface of the core 41. A pushed-on fitting 30 thus adjoins the surface of the core 41 as flush as possible.

Figure 6c shows in the left half of the figure the fitting 30 fully pushed onto the bung spring 415. In this position, the fitting 30 is then fixed by screws 44 which are screwed into countersunk bores 302 made in the side plates 301 close to the edge. The screws 44 are correspondingly countersunk screws which are screwed into the core 41 in the area of the bung spring 415 and which are countersunk as flush as possible in the side plates 301 with their heads. This is in the right hand side of the Figure 6c in one A sectional view is shown which shows the core 41 in the area of the bung spring 415 and the edge area of the fitting 30 attached to the core 41.

Fig. 7 shows in a similar way to Figure 6c an alternative type of connection between the fitting 30 and the core 41. As in the example described above, the core 41 is milled off in the area of the edge of the recess 42, so that a bung spring 415 is formed, onto which the fitting 30 with its parallel side plates 301 is pushed .

In contrast to that in the Figure 6c In the example shown, clamps 45 are used in the present case instead of screws 44 in order to connect the fitting 30 to the core 41 and to prevent the fitting 30 from being pulled forward out of the recess 42. The brackets 45 are guided through corresponding bores in the side plates 301 and hammered into the material of the core 41. In the in Fig. 7 In the illustrated example, the brackets 45 protrude laterally slightly beyond the side surface of the core 41 or the side plates 301. If the cover layers 43a, 43b, not shown here, of the composite element 40 are applied with the aid of an adhesive layer, for example a hot-melt adhesive, this adhesive layer can compensate for the unevenness caused by the clamps 45. Alternatively, it is possible to provide corresponding depressions in the cover layers 301 and the core 41, so that the clips 45 run flush with the rest of the surface of the side plates 301 and the core 41.

Fig. 8 shows a further alternative for connecting the fitting 30 and the core 41 in the same way as that Figures 6c or 7. Here, too, the bung spring 415 is formed in the core 41 and the fitting 30 with the two side plates 301 is plugged onto this bung spring 415, as in FIG Figure 6b is shown.

In order to connect the fitting 30 to the core 41, staples 303 are issued from the material of the side plates 301, which claw into the material of the core 41. The displayed staples 303 are prepared by corresponding punchings in the side plates 301 and are bent inward out after the fitting 30 has been slipped onto the bung spring 415. In the area of the exposed staples 303, small depressions remain in the side plates 301, which, however, are covered by the subsequently applied cover layers 43a, 43b (not shown here). The thickness of the cover layers 43a, 43b is such that these depressions with their small lateral dimensions in the finished composite element 40 are not shown.

Fig. 9 shows a further alternative type of connection between the fitting 30 and the core 41. Here, too, a bung spring 415 is formed on the core 41, the resulting shoulder surfaces 416 being narrower than in the previous examples. A web 304 is arranged between the side plates 301 in sections or around the edge of the fitting 30, which is pushed onto the bung spring 415. The web 304 is spaced from the edge to such an extent that a narrow gap remains between the web 304 and the end face 414 when the fitting 30 is attached. Before the fitting 30 is slipped onto the bung spring 415, an adhesive bead 46 is introduced between the web 304 and the end face 414. This can be one-sided, for example in the form of a hot glue on one of the elements mentioned, for example, as in the Fig. 9 shown, take place on the web 304. Alternatively, it is also conceivable that both elements, the web 304 and the end face 414, are coated with contact adhesive or multi-component adhesive, which sets without being activated by increased temperature when the two elements are pressed onto one another. It is also possible to use an adhesive that is only released when the surfaces to be glued are pressed together. In the left part of the Fig. 9 the contact adhesive bead 46 is shown schematically as a dashed line.

In Fig. 10 Another type of connection, not according to the invention, between a fitting 30 and a core 41 of a composite element 40 is shown.

Unlike the ones in the Figures 6a-c and 7-9 In the examples shown, the end face 414 running along the edge of the recess 42 is not formed exclusively from straight sections that adjoin one another at an angle. Instead, there are undercut connecting elements 417 at several, here for example three points along the end face 414, which in the present case have the shape of a cylinder. Corresponding contours 305 for the connecting elements 417 are cut out in the side plates 301 of the fitting 300. Instead of the shown cylindrical configuration of the connecting element 417 and the corresponding circular segment-shaped configuration of the mating contour 305, other undercut shapes, for example a trapezoidal shape, can also be used.

Of course, the connecting elements can also be arranged conversely on the fitting 30, as can the mating contours receiving them on the core 41.

The core 41 is already connected on one side to a cover layer 43b. In a first assembly step I, the fitting 30 is placed on the unit composed of core 41 and cover layer 43b, so that the respective connecting elements 417 engage in the cut-out counter contours 305 of the side panels 301 as in a puzzle. During assembly, adhesive can be applied to at least selected areas of the side plate 301 or the accessible part of the cover layer 43b in the cutout 42 in order to connect the side plate 301 to the cover layer 43b. Finally, in a second assembly step, the opposite cover layer 43a is glued or laminated onto the core 41 or the facing side plate 301 of the fitting 30.

The examples of composite elements 40 shown so far in FIGS Figures 6a-6c and 7-10 are based on the non-detachable, fixed embedding of the fitting 30 in the composite element 40. Fig. 11 shows another example, not according to the invention, of a composite element 40 with an inserted fitting 30, in which the fitting 30 is pushed from the end face 413 of the composite element into the recess 42 formed. In this embodiment, too, the fitting 30 has two mutually parallel side plates 301 on which levers of the lever mechanism 31 are rotatably mounted and between which the lever mechanism 31 moves when the flap is closed.

In the Fig. 11 the lever mechanism 31 and a two-part flap here with an upper flap part 22 and a lower flap part 23 are shown in an extended state. In the gap formed between the two side plates 301 claws 47 are arranged, which can be opened outwards by means of a tool, for example the illustrated screwdriver 2 in conjunction with screws 48, and which claw into the area of the end face 414 of the core 41. In the area in which the claws 47 extend over the edge of the side plate 301, depressions 418 can be provided in the core 41 to provide support. One of the areas of the claws 47 is in the lower part of the Fig. 11 reproduced enlarged. In an alternative embodiment, comparable claws can also be part of the core 41, with anchoring points which the claws engage in then being formed at a suitable position in or on the fitting 30.

Advantageous at the in Fig. 11 The type of fastening of the fitting 30 shown within the composite element 40 is that a defective fitting 30 can also be removed again and exchanged, which is not possible with the fixed fittings 30 in the examples of the composite element 40 shown above.

In the examples shown, the recess 42 is approximately L-shaped, with a section protruding deeper into the core 41 being arranged in the upper region, in which articulation points for the lever mechanism 31 are also provided. In the lower area, the recess 42 is designed to be less deep. In this area, the fitting 30 only needs to be so deep that, when the flap 20 is closed, the lever mechanism 31 can dip in an orientation that runs essentially parallel to the front end edge 413.

As an alternative to the additional claws 47 used, the fitting 30 can also be screwed directly onto the end face of the core 41 through brackets with bores attached to the fitting 30 or fastened with other fastening means.

Fig. 12 shows an embodiment of a composite element 40, in which the core 41 does not consist of a homogeneous material, but is designed as a composite material. In the edge areas, this core 41 is still made of a compacted material, for example a chipboard, an HDF or an MDF board. In an inner area, in particular in the lower part of the core 41, in which the fitting 30 is made narrower, a light honeycomb structure material 419, for example a cardboard material, is provided. By using the honeycomb structure material, the weight of the composite member 40 and also the material cost can be reduced. In particular in connection with the attached and preferably glued-on cover layers 43a, 43b, sufficient stability of the composite element 40 is nevertheless achieved.

That in the Fig. 12 The composite element 40 shown is also designed for subsequent processing, in particular changing the length and the width of the composite element 40. Dashed cutting lines 3 are given as an example, along which the composite element 40 after its production, i.e. after the integration of the fitting 30 into the core 41 and after the application of the cover layers 43a, 43b, which are not shown here, individually as required can be cut to length. For example, a prefabricated composite element 40 with an already integrated fitting 30 can be used, for example, in carpenter's shops or smaller factories in order to produce custom-made furniture.

Further fittings such as cabinet hangers or connecting elements for, for example, interior organizations or connecting interfaces for the furniture body 10 can be integrated into the composite element 40. For electrification of the composite element 40, electrical lines and also further electrical components can also be integrated in the composite element 40. The integration of lighting equipment such as LED lights is also possible.

The exemplary embodiments relate to furniture in which the doors or flaps are guided by fittings which are largely integrated into vertically arranged side walls or partitions of the furniture.

The fittings 30 shown in the context of this application are each equipped with a lever mechanism 31. Other types of fittings with other types of guidance of coupled movable furniture parts can also be used.

Fig. 13 shows a top view of the front face 413 of a section of a composite element 40 in the area of the fitting 30. In this exemplary embodiment, an edge band 49 is applied as a narrow-side coating to the front face 413 of the core 41 and thus the composite element 40. Further edge banding, not visible here, can be applied in the area of the upper or lower end faces 412 or the rear end face 411.

In the area of the opening of the fitting 30, from which, for example, the lever mechanism 31 (not visible in this illustration) extends, the edge banding 49 is cut out. The edge band 49 is after integration of the fitting 30 in the composite element 40 or after inserting the fitting 30 into the composite element 40 (cf. Fig. 11 ) applied to the front face 413.

The edge banding 49 is cut out in such a way that it rests in sections on the fitting 30 and, for example, covers the edges of the side panels 301 of the fitting 30 or other elements visible outside the opening of the fitting 30. In the Fig. 13 the outlines of the fitting 30 are indicated by dashed lines.

Due to the arrangement of the edge band 49 also on sections of the fitting 30, the fitting 30 - apart from the extendable lever mechanism 31 - is completely integrated into the composite element 40 and is no longer visible on the front face 413 of the composite element 40.
