DETAILED DESCRIPTION
[0040]
[0041] The wall unit comprises a furniture body 10 with a bottom panel 11, top panel 12, and two side walls 13. A rear wall is preferred for reasons of stability but is not shown in this embodiment example.
[0042] The furniture body 10 is open to the front to allow access to the interior of the cupboard. A flap arrangement 20 with an integral flap 21 is provided to close the opening of the furniture body 10. The integral flap 21 is pivoted along its upper horizontal side edge. For this purpose, fittings 30 are provided that are connected to the integral flap 21 with a lever mechanism 31 in the upper part of the flap 21.
[0043] The fittings 30 (with the exception of the lever mechanism 31 extended in the opening position shown) are arranged within the respective side wall 13. When flap 21 is closed, the lever mechanism 31 may be fully retracted into the side wall 13, optionally except for the mounting elements for connecting it to flap 21. The area within the side wall 13 in which the fitting 30 is located is indicated by a dashed line in
[0044] The side wall 13 is characterized by side surfaces 131, which are ideally integral and can have the same surface texture throughout the entire surface. The surface of the integral side surfaces 131 can create design effects through different patterns, surface textures, or different colors. This preferably applies both to an outer side surface 131 and to an inner side surface 131 facing the interior of the furniture body 10. The side walls 13 also have an end face 132, which has an opening 133 in the area of the fitting 30, into which the lever mechanism 31 of the fitting 30 dips or from which the lever mechanism 31 extends. When the flap arrangement 20 is closed, the lever mechanism 31 is completely immersed in the opening 133, except for any fastening means with which it is connected to the integral flap 21.
[0045] According to the application, the side walls are 13 composite elements, which are explained in more detail in connection with the
[0046]
[0047] As in the example in
[0048] As in the embodiment example of
[0049]
[0050] This piece of furniture has a two-part flap arrangement 20 with an upper flap part 22 and a lower flap part 23. Again, the side walls 13 are designed as composite elements which accommodate a fitting 30. This is coupled with lever mechanisms 31 both with the upper flap part 22 and with the lower flap part 23. In addition, additional hinges 25 are provided to connect the upper and lower flap parts 22, 23 with each other along their connecting line. Depending on the design of the flap fitting, the hinges can also be omitted.
[0051] As in the embodiment example for
[0052]
[0053] The flap arrangement 20 is comparable with the embodiment example of
[0054] In all the embodiment examples shown, the composite elements are characterized by continuous side surfaces with a uniform surface look and feel across the entire surface. In particular, no transition in the area of the edge of the fitting 30 is discernible in the surface.
[0055] The basic structure of a first embodiment example of a composite element 40 with which this is achieved is shown in
[0056] The composite element 40 has a core 41, for example made of chipboard or medium or high density fiberboard (MDFMedium Density Fiberboard or HDFHigh Density Fiberboard). The core 41 has a rectangular offset of the size which later has the sides or partition wall in the furniture body to be manufactured (cf. e.g. side wall 13 of furniture body 10 according to the embodiment examples in
[0057] The core 41 has a large, flat recess 42, which is open towards a fourth end face 413. Only in the upper and lower part of the core 41 a narrow section of the end face 413 remained on this side. In the area in between, the edge of the recess 42 now forms an inwardly offset end face 414 that follows the contour of the recess 42.
[0058] The contour of the recess 42 corresponds to the outer contour of a fitting 30 to be inserted, here an approximately L-shaped contour. For example, the recess 42 can be milled into the core 41 using the symbolic milling tool 1. Other cutting techniques such as drilling in conjunction with (dip) saw cuts can also be used to create the recess 42. It should be noted that machining can be performed from one of the side surfaces of core 41. Machining only from the end face 413 is not required for core 41, which is initially available separately. Thus, the recess can easily accept any depth (as seen from the original end face 413) and is also suitable for fittings 30 with a large installation depth. The lateral machining direction can also be used to create contours that are not possible by machining only from the end face 413.
[0059] After inserting the recess 42 into 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 described in more detail in connection with
[0060] The fitting 30 and the core 41 preferably have the same thickness, especially in a range from 15 mm to about 20 mm. The core 41 and the fitting 30 thus form a unit in which the fitting 30 is flush with the surface of the core 41 on both sides. In addition, the front edges of fitting 30 are flush with the two remaining sections of the actual end face 413 of core 41.
[0061] In a second assembly step II, which in turn is indicated by corresponding arrows in
[0062] 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. If necessary, this step can also be carried out before applying the cover layers 43a, 43b and also before inserting the fitting 30.
[0063] In the manner described, the composite element 40 is created, which in this form can directly form a side wall 13 or a partition wall 14 of a furniture body 10 as shown in
[0064]
[0065]
[0066]
[0067] Fitting 30 has two side plates 301 spaced apart from each other, which laterally limit fitting 30 and provide the pivot points for lever mechanism 30. Distance sleeves or bolts are preferably arranged between the side plates 301, which connect the side plates 301 to each other and fix them parallel to each other at a fixed distance. In alternative embodiments of the fitting 30, screw elements can also serve as spacers, which offer the possibility of varying the spacing of the side plates 301 at least slightly and thus adapting it to the thickness of the core 41.
[0068] 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 core 41, as shown in
[0069]
[0070]
[0071] In contrast to the example shown in
[0072]
[0073] To connect a fitting 30 with a core 41, staples 303 protrude from the material of side plates 301, which claw into a material of a core 41. The exhibited staples 303 are prepared by appropriate cutouts in the side plates 301 and are bent out inwards after the fitting 30 has been attached to the bung spring 415. In the area of the protruding staples 303, small depressions remain in the side plates 301, which, however, are covered by the subsequently applied cover layers 43a, 43b, which are not shown here. The thickness of the cover layers 43a and 43b is such that these recesses with their small lateral dimensions are not visible in the finished composite element 40.
[0074]
[0075]
[0076] In contrast to the examples shown in
[0077] It is understood that the connecting elements can also be arranged in reverse on fitting 30, and the mating contours accommodating them can also be arranged on core 41.
[0078] The core 41 is already connected on one side with a cover layer 43b. In a first assembly step I, fitting 30 is placed on the unit consisting of core 41 and cover layer 43b, so that the respective connecting elements 417 engage in the cutout mating contours 305 of the side plates 301 as in a puzzle. When assembling, adhesive can be applied to at least selected areas of the side plate 301 or the accessible part of the cover layer 43b in cutout 42 to connect the side plate 301 to the cover layer 43b. Finally, in a second assembly step II, the opposite cover layer 43a is glued or laminated onto the core 41 or the facing side plate 301 of fitting 30.
[0079] The embodiment examples of composite elements 40 shown so far in
[0080]
[0081] The advantage of the type of fastening of fitting 30 within the composite element 40 shown in
[0082] In the embodiment examples shown, the recess 42 is approximately L-shaped, wherein a section projecting deeper into the core 41 is arranged in the upper area, in which hinge points for the lever mechanism 31 are also provided. In the lower area, the recess 42 is less deep. In this area, the fitting 30 only needs to be deep enough that, when the flap 20 is closed, the lever mechanism 31 can be immersed in an orientation essentially parallel to the front edge 413.
[0083] As an alternative to the additional claws 47 used, the fitting 30 can also be screwed directly to the core 41 at the front end by means of brackets with holes attached to the fitting 30 or fastened with other fastening means.
[0084]
[0085] The composite element 40 shown in
[0086] Further fittings such as cabinet hangers or connecting elements for e.g., interior organization or connecting interfaces for furniture body 10 can be integrated into the composite element 40. Electrical cables and other electrical components can also be integrated into the composite element 40 for electrification of the composite element 40. The integration of lighting equipment such as LED luminaires is also possible.
[0087] The embodiment examples relate to pieces of furniture in which the doors or flaps are guided by fittings which are largely integrated into vertically arranged side walls or partition walls of the furniture.
[0088] The fittings 30 shown as part 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.
[0089]
[0090] 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 band 49 is recessed. The edge band 49 is applied to the front end face 413 after integration of fitting 30 into the composite element 40 or also after insertion of fitting 30 into the composite element 40 (see
[0091] The edge band 49 is cut out so that it rests in sections on fitting 30 and covers, for example, the edges of the side plates 301 of fitting 30 or other elements visible outside the opening of fitting 30. In
[0092] Due to the arrangement of the edge band 49 also on sections of the fitting 30, the fitting 30with the exception of the extendable lever mechanism 31is completely integrated into the composite element 40 and no longer visible at the front end face 413 of the composite element 40.
[0093] Although the invention has been illustrated and described in detail by way of preferred embodiments, the invention is not limited by the examples disclosed, and other variations can be derived from these by the person skilled in the art without leaving the scope of the invention. It is therefore clear that there is a plurality of possible variations. It is also clear that embodiments stated by way of example are only really examples that are not to be seen as limiting the scope, application possibilities or configuration of the invention in any way. In fact, the preceding description and the description of the figures enable the person skilled in the art to implement the exemplary embodiments in concrete manner, wherein, with the knowledge of the disclosed inventive concept, the person skilled in the art is able to undertake various changes, for example, with regard to the functioning or arrangement of individual elements stated in an exemplary embodiment without leaving the scope of the invention, which is defined by the claims and their legal equivalents, such as further explanations in the description.
