Description

Technical Field

[0001] The present invention relates to an assembly comprising a drawer bottom and a drawer rear wall and / or a drawer front wall, wherein the drawer bottom is articulatedly connected to the drawer rear wall and / or the drawer front wall for transferring the assembly from a transport position into a usage position. The present invention also relates to a kit comprising such an assembly and at least one furniture fitting and / or at least one drawer side wall. Furthermore, the present invention relates to a drawer comprising at least one such assembly. Furthermore, the present invention relates to a method for producing such an assembly and a method for assembling a drawer using such an assembly. Background Art

[0002] EP 1 508 286 B1 discloses folding a furniture component in the form of a furniture rear wall, which consists of a plurality of subsections and holding them together by means of fasteners in such a way that the subsections of the furniture component do not unfold during transport. The folding saves storage space for transporting the furniture component, while the fasteners increase the stackability of the furniture component.

[0003] A disadvantage of the prior art is that folding furniture components does not offer optimal storage space utilization, as the area between the free end and the fold must remain free in the folded position to allow for folding without damaging the furniture component. Furthermore, the subsections of the furniture component bend in the fold region, significantly increasing the risk of damage to the furniture component. Furthermore, a unique folding method is required for each furniture component, and the external dimensions of different folding furniture components are often not identical, making transportation more difficult and wasting transport space. Furthermore, the thickness of the folding furniture component increases significantly with the number of folds. In the case of three subsections, the thickness of the subsections increases by at least three times after two folds, which (particularly due to the necessary bending in the fold region) impairs stacking or reduces available storage space. Furthermore, the bending in the fold region causes the subsections to spread apart, making fasteners essential for transport. However, the fasteners subject the material of the subsections to greater bending or stress in the fold region.

[0004] From US Pat. No. 10,362,872 B1, it is known to connect a drawer bottom and a drawer rear wall to each other via a hinge so that they can be pivoted between two positions, so that the drawer rear wall can be folded in the direction of the drawer bottom. This reduces the storage space required for transport by simply lowering the height of the furniture component to be transported, but hinges are necessary as additional structural components and must be positioned and installed correctly for adequate functionality. However, due to the expansion of the hinges, the drawer rear wall cannot be flattened. Arranged on a drawer bottom, a bend occurs in the region of the fold, which can lead to damage to the furniture component. Summary of the Invention

[0005] The technical object of the present invention is therefore to provide an improved assembly consisting of a drawer bottom and a drawer rear wall and / or a drawer front wall compared to the prior art, in which the disadvantages of the prior art are at least partially eliminated and which is distinguished in particular by a particularly compact transport position and / or by user-friendly handling during assembly and / or transport. The present invention is also directed to providing an improved drawer and an improved method for producing a drawer and for producing such an assembly.

[0006] This object is achieved by the features of claim 1 and claims 22 to 26 .

[0007] According to the invention, it is therefore provided that the drawer bottom comprises at least two drawer bottom sections which are connected to one another in an articulated manner for transferring the assembly from the transport position into the usage position.

[0008] This allows a particularly compact implementation of the transport position of the assembly by additional folding of the drawer bottom (between the first and second drawer bottom sections) in addition to the folding between the drawer rear wall and the drawer bottom (first drawer bottom section).

[0009] The following positive properties are also present: the transport position is particularly stable and has a geometry that prevents pressure points and / or damage on the drawer bottom and the drawer rear and / or drawer front walls due to folding. To install the drawer, the assembly can be moved into the operating position by unfolding it without tools.

[0010] Furthermore, it can be ensured that, for example, sensitive surfaces to which the decorative coating is applied can be stored in a particularly advantageously protected manner, in particular during storage and / or transport.

[0011] By adapting the positioning of the hinged connection of the drawer bottom to the longitudinal extension of the drawer rear wall (corresponding to the height of the drawer rear wall in the use position), in particular so that the free end of the drawer rear wall is arranged close to the free end of the drawer bottom or the drawer front wall (for example with a gap in the range of the material thickness of the drawer bottom or below the material thickness), the transport position can be optimized with regard to the necessary storage space in this regard.

[0012] For the compact transport position, it is generally unimportant whether the drawer bottom is connected in an articulated manner to the drawer rear wall and / or the drawer front wall. Preferably, the drawer bottom is arranged on the drawer rear wall in the transport position (since the drawer front wall may have a separate decorative layer and / or geometric shape for improved visibility in the use position) and optionally also on the drawer front wall in the transport position.

[0013] As explained at the outset, a kit is also claimed, which consists of such a component, in particular in the transport position, and at least one furniture fitting, in particular a guide rail, a rear wall bracket and / or a front wall bracket, and / or at least one drawer side wall.

[0014] As a result, the drawer can be installed, for example, by non-specialists without requiring specialized knowledge, which facilitates delivery to the user (particularly with regard to its effort and costs).

[0015] Preferably, the drawer bottom, the drawer rear wall and / or the drawer front wall are constructed from wood or timber. Preferably, the drawer side walls and / or furniture fittings for arrangement at the drawer bottom, the drawer rear wall and / or the drawer front wall are constructed from metal and / or timber, although this is generally not absolutely necessary (plastic is also conceivable as a material).

[0016] In general, the hinged connection can be designed as a flexible layer, which can be designed, for example, in the form of a coating, as a foil hinge, and / or as a film hinge, and / or as an adhesive hinge. The flexible layer can be designed to articulate the drawer bottom to the drawer rear wall and / or the drawer front wall, wherein the flexible layer can be arranged, for example, at two adjacent panel elements (particularly preferably between the drawer bottom and the drawer rear wall and / or between drawer bottom sections) and / or can extend at least partially across two spatially separated panel elements (particularly preferably between the drawer bottom and the drawer front wall) in order to produce the hinged connection of the panel elements. Particularly preferably, the hinged connection or the flexible layer is in the form of a flexible foil or a hot melt adhesive layer.

[0017] As explained at the outset, protection is also claimed for a drawer comprising at least one such component or such a kit in the use position, wherein the drawer bottom and / or the drawer rear wall and / or the drawer front wall are arranged on at least one drawer side wall via at least one fastening element, in particular at least one furniture fitting.

[0018] The at least one fixing element preferably connects the drawer bottom to the at least one drawer side wall in a clamping manner.The at least one fixing element can be a part of the drawer side wall or a furniture fitting.

[0019] At least one furniture fitting preferably connects the drawer rear wall to at least one drawer side wall, wherein it is preferably provided that the at least one furniture fitting ensures an angle of substantially 90 degrees relative to the drawer bottom. For example, the furniture fitting can include a clamping area and / or screws.

[0020] For example, a drawer that can be moved relative to the furniture body by guide rails can be called a drawer. Particularly preferred are drawers in which the height of the drawer rear wall and / or the drawer front wall is small, preferably a maximum of one-third, particularly preferably a maximum of one-fifth, of the longitudinal extension of the drawer bottom.

[0021] Preferably, in particular in the folded transport position, the assembly comprises exactly three or exactly four sections or components, wherein it is particularly preferably provided that one section or component is formed by the drawer rear wall, two sections or components are formed by the drawer bottom and, if applicable, one section or component is formed by the drawer front wall.

[0022] The assembly is particularly preferably configured for use with a drawer or drawer box. The transport position is preferably characterized by a drawer rear wall and / or a drawer front wall folded onto the drawer bottom and / or a second drawer bottom section folded onto the first drawer bottom section.

[0023] As explained at the outset, a method for producing such a component is also claimed, wherein the following method steps are preferably carried out in chronological order:

[0024] The at least two drawer bottom sections and the drawer rear wall and / or the drawer front wall are provided by machining from a plate-like starting material,

[0025] - hingedly connecting the first drawer bottom section and at least one second drawer bottom section, the drawer rear wall and / or the drawer front wall to one another by means of a flexible layer, preferably an adhesive layer or a flexible foil, to form at least one film hinge or adhesive hinge,

[0026] or

[0027] - a sheet-shaped starting material is provided with a flexible layer, preferably an adhesive layer or a flexible foil,

[0028] - machining the plate-shaped starting material in sections, in particular down to the flexible layer, so that the flexible layer in the form of at least one film hinge or adhesive hinge connects the first drawer bottom section to at least one second drawer bottom section and the drawer rear wall and / or the drawer front wall in an articulated manner to one another.

[0029] For example, cutting, milling, sawing, separating, chamfering, etc. can be used as cutting processing methods.

[0030] For example, the board-shaped starting material can be present in the form of a wood board (for example fiberboard or particleboard), preferably with a decorative coating.

[0031] As explained at the outset, a method for assembling a drawer with such an assembly is also claimed, wherein the following method steps are preferably performed in chronological order:

[0032] - providing the assembly in a transport position, wherein the at least one second drawer bottom section and / or the drawer rear wall and / or the drawer front wall is folded onto the first drawer bottom section, in particular with a planar contact substantially over the entire longitudinal extension of the at least one second drawer bottom section and / or the drawer rear wall and / or the drawer front wall,

[0033] - transferring the assembly from the transport position into the use position, wherein the drawer rear wall and / or the drawer front wall are unfolded substantially 90 degrees relative to the first drawer bottom section and / or the second drawer bottom section is unfolded substantially 180 degrees relative to the first drawer bottom section,

[0034] - if possible, the drawer front wall is opened substantially 90 degrees relative to the second drawer bottom section and / or preferably together with the second drawer bottom section is opened substantially 180 degrees relative to the first drawer bottom section,

[0035] The drawer bottom and / or the drawer rear wall and / or the drawer front wall are arranged on at least one drawer side wall via at least one fastening element, in particular at least one furniture fitting.

[0036] According to the invention, it is possible to provide a so-called fully skinned drawer solution, in which, for example, a wood panel is cut into individual parts, pushed together and coated with adhesive, and then a skin material (such as skin paper or foil) is applied, so that the resulting hinge is located in the skin material. It is also conceivable to place the skin material around the narrow edge of the drawer rear wall.

[0037] Advantageous embodiments of the invention are defined in the dependent claims.

[0038] It is particularly preferred that the drawer bottom is hingedly connected to the drawer rear wall and / or the drawer front wall by at least one film hinge or adhesive hinge, in particular a flexible foil and / or a film formed by hot melt adhesive, and / or the drawer bottom is hingedly connected to the drawer rear wall and / or the drawer front wall, so that the drawer rear wall and / or the drawer front wall are placed on the drawer bottom in a partial area on the end side in the use position, preferably placed on the drawer bottom in a planar manner, particularly preferably placed on the drawer bottom in a planar or linear manner.

[0039] This makes it possible to arrange the end faces of the drawer rear wall and / or drawer front wall in the area of ​​the drawer bottom above the drawer bottom without requiring metal hinges or separate mechanical hinges to connect the drawer bottom to the drawer rear wall and / or drawer front wall, wherein the drawer rear wall and / or drawer front wall can be supported with the end faces, in particular directly, on the surface of the drawer bottom. The contact with the drawer bottom can be made directly or indirectly via film hinges or adhesive hinges, thereby making it possible to provide a substantially flat connection to the drawer bottom, wherein the film hinges or adhesive hinges can be considered an integral component of the drawer rear wall and / or drawer front wall.

[0040] According to an advantageous design scheme of the present invention, it is provided that the component includes a drawer rear wall and a drawer front wall, wherein the drawer rear wall and the drawer front wall are hingedly connected to the drawer bottom for converting the component from a transport position to a usage position, wherein it is preferably provided that the drawer rear wall includes at least two drawer rear wall sections and / or the drawer front wall includes at least two drawer front wall sections, and the drawer rear wall sections and / or the drawer front wall sections are hingedly connected to each other.

[0041] In general, it is also possible that in the transport position of the arrangement no drawer front wall is provided, but the drawer rear wall is divided into at least two drawer rear wall sections which are connected in an articulated manner to one another.

[0042] If a drawer rear wall and a drawer front wall are provided, the following explanations regarding the second drawer bottom section relate in an analogous manner to the relative positioning of the drawer front wall, for example the free end of the drawer rear wall, relative to the other free end (of the drawer bottom or the drawer front wall).

[0043] Generally speaking, the second drawer bottom section can be subdivided into more second drawer bottom sections, wherein preferably at least one second drawer bottom section is connected to the drawer front wall or is configured to have a free end for flush arrangement or docking arrangement relative to the drawer rear wall.

[0044] Advantageously, it is provided that the component comprises at least two, preferably exactly two or exactly three drawer layers in the transport position, wherein it is preferably provided that the drawer bottoms are arranged in at least two of the at least two drawer layers, and / or the drawer rear wall and / or the drawer front wall are arranged in only one of the at least two drawer layers, and / or one drawer layer is formed only by the drawer bottom.

[0045] For example, a first drawer layer may comprise a drawer bottom, a second drawer layer (preferably arranged in the middle) may comprise a drawer rear wall and at least one second drawer bottom segment, and a third drawer layer may comprise a drawer front wall. Generally speaking, in the case of finer segmentation, for example, at least one drawer rear wall segment may also be present in the first drawer layer. Generally speaking, the drawer bottom in the first drawer layer may also be subdivided into a plurality of segments, wherein the plurality of segments may be used to form a further drawer layer, for example, in order to reduce the longitudinal extension of the transport position.

[0046] It has proven to be expedient if at least one drawer layer comprises two components, preferably spaced apart from one another by a gap, wherein the longitudinal extension of the first component, preferably the drawer rear wall or the drawer front wall, is not equal to, preferably is smaller than, the longitudinal extension of the second component, preferably the second drawer bottom section.

[0047] The gap allows the two components to be folded together flatly without damaging the edges during the folding process. Preferably, the gap is less than twice the material thickness, particularly preferably less than the material thickness of the drawer bottom.

[0048] Due to the different longitudinal extensions of the two components or the asymmetrical division ratio of the sections in the drawer layer, the storage space can be ideally utilized, especially taking into account the longitudinal extension of the drawer rear wall (corresponding to the height), and / or folding into two drawer layers with a thickness of essentially exactly two material thicknesses can be achieved.

[0049] According to an advantageous embodiment of the invention, the two components are connected to one another via a transport lock for mutually secure positional alignment.

[0050] This prevents the drawer layers from opening unintentionally.

[0051] It is particularly preferably provided that at least two of the at least two drawer layers are in surface contact with each other in the transport position of the assembly, wherein it is preferably provided that at least one drawer layer comprises two components, wherein the surface contact exists essentially over the entire longitudinal extension of the first component and / or the second component.

[0052] This reduces the thickness in the transport position, preventing surface damage due to line contact with the edges. Generally, film hinges arranged between the drawer layers (which are only partially arranged in the area of ​​the hinge connection) result in a slight spacing between the drawer layers in the area of ​​the hinge connection. However, this spacing is sufficiently small that, due to slight elastic deformation of the preferably flexible drawer layers, the drawer layers achieve surface contact, in particular substantially up to the film hinge. Particularly preferably, the material thickness of the film hinge is negligible compared to the material thickness of the drawer bottom and / or drawer rear wall, preferably less than one-fifth, particularly preferably less than one-tenth.

[0053] An advantageous variant of the invention is that the drawer rear wall and / or the drawer front wall are arranged completely flush with the drawer bottom section and / or parallel to the drawer bottom section in the transport position, wherein it is preferably provided that, in the use position, the drawer bottom is arranged orthogonal to the drawer rear wall and / or the drawer front wall.

[0054] In other words, in the transport position the drawer rear wall does not span the adjacent second drawer bottom section and / or drawer front wall (flush arrangement), and / or adjacent panel parts are arranged abuttingly (with a small gap) relative to each other.

[0055] It is particularly preferably provided that, in the transport position, the free end of the drawer rear wall adjoins the drawer bottom or the other free end of the drawer front wall, preferably lying opposite in the board plane, or that, in the transport position, the free end of the drawer front wall adjoins the other free end of the drawer bottom, preferably lying opposite in the board plane.

[0056] In particular, through the asymmetrical segmentation of the two components of the drawer layer, a flush and / or adjacent docking arrangement of the two free ends (almost touching and / or with a gap within the material thickness) is possible, wherein the two components can be flexibly adapted to the desired dimensions of the transport position and / or the changed longitudinal extension of the drawer rear wall.

[0057] It is particularly preferably provided that the drawer front wall in the transport position of the assembly has a width which is preferably substantially greater by two material thicknesses than the width of the drawer bottom and / or the drawer rear wall.

[0058] This facilitates the assembly of the drawer front wall and the side walls of the drawer together in the use state.

[0059] In one embodiment of the invention, it is provided that the at least two drawer bottom sections and / or the drawer bottom and the drawer rear wall and / or the drawer front wall are foldable relative to one another and are particularly preferably materially connected to one another, preferably without further mechanical means.

[0060] In this context, "without further mechanical means" means, for example, an articulated connection via a film hinge (e.g., a flexible foil) or an adhesive hinge (e.g., a layer of hot-melt adhesive applied at least in sections), which can be connected to the drawer bottom, thereby eliminating the need for a separate structural component connected externally to the drawer bottom. In this context, "material connection" means that the articulated connection (e.g., a film hinge) is an integral component of the drawer bottom (and / or the drawer rear wall and / or the drawer front wall), wherein the articulated connection is, for example, a layer of a layer structure.

[0061] According to a preferred embodiment of the invention, a first articulated connection is preferably provided between the drawer bottom and the drawer rear wall and / or the drawer front wall, which is constructed in such a way that a pivoting movement of essentially 90 degrees can be performed in the transition between the transport position and the usage position of the component.

[0062] Generally speaking, a pivoting movement through 90 degrees can be limited by chamfering the edges (or adhesive connections). However, it is generally sufficient to secure a pivoting movement of essentially 90 degrees for establishing the use position by connection to another structural component (e.g., a drawer side wall and / or furniture fitting). This simplifies the production process, wherein the at least one first articulated connection can be designed in a similar manner to the at least one second articulated connection (with a butt-jointed arrangement connected by adhesive).

[0063] It has proven to be expedient to provide at least one second articulated connection, preferably between at least two drawer bottom sections, which is designed such that a pivoting movement of essentially 180 degrees can be performed during the transition between the transport position and the usage position of the assembly.

[0064] Furthermore, it is preferably provided that the first articulated connection and / or the at least one second articulated connection is formed by at least one film hinge or adhesive hinge, preferably a flexible foil and / or a film made of hot melt adhesive, particularly preferably a PU-based hot melt adhesive.

[0065] An adhesive particularly useful for a preferably localized adhesive layer is an elastic lacquer that can be flexibly deformed into an articulated connection in the sense of a film hinge. A permanently flexible PU adhesive is preferably used, while the hinge can alternatively be formed with a particularly preferably hard EVA adhesive (hotmelt adhesive based on ethylene-vinyl acetate copolymer). The EVA adhesive can be applied to the edge, and then a flexible material (such as a foil, textile strip, etc.) can be placed to separate the bonding / connection process from the hinge effect. Solid adhesives and / or flexible edge materials have proven particularly suitable for articulated connections when used in drawers.

[0066] For example, a film hinge may denote a local arrangement (in the longitudinal extension and / or orthogonal to the longitudinal extension) of adhesive and / or adhesive layers in a layered arrangement of a drawer bottom, a drawer rear wall and / or a drawer front wall.

[0067] In another embodiment of the invention, it can be provided that, preferably in the longitudinal extension and / or in a direction transverse to the longitudinal extension, the at least one film hinge or adhesive hinge is arranged only partially in the area of ​​the first hinged connection and / or at least one second hinged connection, or is arranged completely at the drawer bottom, the drawer rear wall and / or the drawer front wall.

[0068] According to an advantageous design of the invention, it is provided that the drawer bottom and / or the drawer rear wall and / or the drawer front wall comprise a layer structure, wherein the layer structure comprises: a carrier layer, a flexible layer, preferably an adhesive layer, a film hinge or an adhesive hinge, particularly preferably in the form of a PU-based hot melt adhesive and / or a flexible foil, and / or a cover layer if possible, wherein it is preferably provided that the flexible layer is arranged at the carrier layer and / or the cover layer, particularly preferably in the folding direction from the use position to the transport position and / or away from the folding direction from the use position to the transport position, and / or the carrier layer is removed in the area of ​​the hinged connection, and the flexible layer acts as a hinge between the drawer bottom and the drawer rear wall and / or the drawer front wall.

[0069] The carrier layer is preferably in the form of wood or a wood board, such as fiberboard or particleboard. The cover layer is preferably a decorative layer for the drawer, which can be arranged on the inside in the transport position for protection against defects or on the outside due to characteristic material properties (such as hardness). Adhesive layers can also be arranged between the drawer layers and / or outside the drawer layers.

[0070] Generally speaking, only a carrier layer can also be provided in the layer structure, for example when no decorative layer is provided and the film hinge or adhesive hinge is arranged at the end in the transport position. For example, layer structures are possible in which a carrier layer is provided between a flexible layer and a cover layer (e.g. a decorative layer), or a flexible layer is provided between a cover layer and a carrier layer.

[0071] It is also conceivable that the film hinge is formed by the cover layer, for example when the cover layer is configured as an elastic lacquer layer. In this case, the adhesive layer can be omitted.

[0072] According to a preferred embodiment, it is provided that the assembly comprises at least two drawer layers in the transport position, wherein the cover layer is arranged at least partially between the two drawer layers in the transport position of the assembly and / or the cover layers of the drawer layers are arranged so as to point towards each other.

[0073] It is particularly preferably provided that the assembly, preferably the casing of the assembly, is of substantially rectangular design in the transport position, wherein preferably all opposite side faces are designed to be congruent with one another.

[0074] Rectangular modules can be stacked and transported particularly conveniently. If the opposing side surfaces are constructed to be consistent with one another, the amount of air required for the storage space of the module is reduced, which is not the case with overlapping folds.

[0075] It is particularly preferred that at least two drawer bottom sections have different longitudinal extensions. Generally, the longitudinal extensions of the drawer bottom sections are adapted so that in the transport position, the free ends are arranged adjacent to each other. In the case of finer segmentation of the drawer bottom, generally, all drawer bottom sections of one drawer layer can also be considered as first drawer bottom sections, while all drawer bottom sections of another drawer layer can be considered as second drawer bottom sections.

[0076] If it is provided that the drawer front wall is arranged on the second drawer bottom section in the transport position, the longitudinal extension of the drawer front wall can be taken into account in the longitudinal extension of the second drawer bottom section and / or the drawer front wall can be arranged in another drawer level.

[0077] According to an advantageous design of the present invention, at least one drawer side wall is provided, wherein the drawer bottom is preferably hingedly connected to at least one of the at least one drawer side wall via at least one film hinge or adhesive hinge for converting the component from a transport position into a usage position.

[0078] The drawer side walls can thus also be contained in the transport position, wherein for example the drawer side walls can be folded relative to the drawer rear wall onto one side of the drawer layer and onto the side of the drawer layer facing away therefrom to form a further drawer layer.

[0079] It is advantageously provided that, in the transport position, at least one second drawer bottom section and / or drawer rear wall and / or drawer front wall is folded onto the first drawer bottom section, preferably with surface contact substantially over the entire longitudinal extension of the at least one second drawer bottom section and / or drawer rear wall and / or drawer front wall, wherein it is preferably provided that the free end of the at least one second drawer bottom section is spaced apart from the free end of the drawer rear wall and / or drawer front wall by a gap in the order of magnitude of the material thickness of the drawer bottom, particularly preferably at a maximum by the material thickness of the drawer bottom.

[0080] The assembly is thus present in a compact packaging which can be moved particularly conveniently from the production site to the installation site.

[0081] It is particularly preferably provided that the flexible layer or the film hinge or the adhesive hinge is preferably arranged at least partially in the area of ​​at least one inclined surface, preferably in the area of ​​a recess and / or at least one step and / or at least one tongue and groove of at least one drawer bottom section and / or a drawer rear wall and / or a drawer front wall, wherein it is preferably provided that the film hinge or the adhesive hinge is arranged in the area of ​​the recess and / or the at least one step and / or the at least one tongue and groove.

[0082] As a result, a folding connection with particularly high stability and / or an increased service life in the loaded state can be achieved. The use of tongue and groove is particularly advantageous for fixing in the use state of the component as a drawer.

[0083] It is particularly preferably provided that at the free end of the drawer bottom and / or the drawer rear wall and / or the drawer front wall at least one covering element, preferably in the form of an adhesive, a foil and / or a profile, is provided, preferably via at least one retaining device, for covering at least one edge surface.

[0084] As a result, the aesthetic appearance of the component can be improved, and the risk of injury during use of the component can also be significantly reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0095] FIG1 shows the assembly in a use position 5, comprising a drawer bottom 1 and a drawer rear wall 2, wherein the drawer bottom 1 is hingedly connected to the drawer rear wall 2 for moving the assembly from a transport position 4 (see FIG1 ). Figure 1b ) is switched to use position 5.

[0096] In general, a drawer front wall 8 can be used as an alternative or in addition to the drawer rear wall 2. However, the use of a connection between the drawer bottom 1 and the drawer rear wall 2 is particularly preferred, especially because the drawer rear wall 2 is less visible in the drawer 32 and / or generally does not include a decorative layer. The dimensioning of the drawer rear wall 2 can be flexibly considered by segmenting the drawer bottom 1. In general, a drawer side wall 3 can also be included in addition, which is arranged in the transport position 4 via hinged connections 21, 22.

[0097] The drawer bottom 1 comprises two drawer bottom sections 6 , 7 which are connected to one another in an articulated manner for transferring the assembly from the transport position 4 into the use position 5 .

[0098] The assembly comprises a first articulated connection 21 between the first drawer bottom section 6 of the drawer bottom 1 and the drawer rear wall 2, wherein the first articulated connection 21 is formed by a film hinge 23 in the form of an adhesive, which is a polyurethane (PU) adhesive. The first articulated connection 21 is designed such that, when transitioning between the transport position 4 and the use position 5 of the assembly, a 90-degree pivoting movement can be performed, which can generally be secured by a furniture fitting 29 or the drawer side wall 3, so that during installation, the 90-degree end position of the drawer rear wall 2 in the use position 5 relative to the transport position 4 is stabilized, for example, by the connection of the drawer rear wall 2 to the drawer side wall 3.

[0099] In general, it is also conceivable that the film hinge 23 or the cutout of the drawer rear wall 2 or the drawer bottom 1 in the region of the film hinge 23 limits the pivoting movement beyond 90 degrees by tension or geometry in the end position. For example, the cutout of the drawer rear wall 2 can have a cutout angle other than 180 degrees relative to the cutout of the drawer bottom 1, but this is generally not necessary.

[0100] The assembly comprises a second articulated connection 22 between the two drawer bottom sections 6, 7, which is designed so that a pivoting movement of substantially 180 degrees can be performed when the assembly transitions between the transport position 4 and the use position 5. The two drawer bottom sections 6, 7 are slotted relative to each other so that a cutout angle of 180 degrees exists between the drawer bottom sections 6, 7 (particularly at the Figures 9a to 9d Various such possible connections of the panel parts are shown in FIG. 1 by means of hinged connections 21 , 22 via flexible layers such as adhesive hinges or film hinges 23 ).

[0101] The first articulated connection 21 and the second articulated connection 22 are formed by a film hinge 23 , which is in the form of a PU adhesive.

[0102] The two drawer bottom sections 6, 7 and the drawer rear wall 2 each have a first cover surface 17 and a second cover surface 18. In the transport position 4 of the assembly, the first and second cover surfaces 17, 18 of the drawer rear wall 2 and the second drawer bottom section 7 are arranged parallel to the first drawer bottom section 6 (i.e., the first and second cover surfaces 17, 18 of the first drawer bottom section). In the use position 5, the first and second cover surfaces 17, 18 of the drawer bottom 1 are arranged orthogonally to the first and second cover surfaces 17, 18 of the drawer rear wall 2, the drawer side walls 3, and the drawer front wall 8. It is also conceivable that the drawer front wall 8 has a different layer structure 24 than the drawer bottom 1 or the drawer rear wall 2.

[0103] according to Figure 1a and Figure 1bThe drawer bottom 1, the drawer rear wall 2 and the drawer front wall 8 of the embodiment of the invention comprise a layer structure 24, wherein the layer structure 24 comprises a carrier layer 25, an adhesive layer 27 in the form of a PU adhesive layer and a cover layer 26 as a decorative layer (see Figure 1a and Figure 1b ).

[0104] Generally speaking, the cover layer 26 in the layer structure 24 can be omitted. Generally speaking, the adhesive layer 27 can be arranged on the carrier layer 25 and / or the cover layer 26. Generally speaking, the adhesive layer 27 can be arranged only partially or completely on the component parts involved in the folding. Generally speaking, in the use position 5 or the transport position 4, the adhesive layer 27 can be arranged inside (i.e. between the drawer layers 11) or outside (i.e. outside the drawer layers 11). Generally speaking, the adhesive layer 27 can be arranged partially or flatly in the folding direction 30 from the use position 5 to the transport position 4 and / or arranged away from the folding direction 30 from the use position 5 to the transport position 4.

[0105] Figure 1b The assembly is shown in a transport position 4 , in which the assembly is transferred from the usage position into a folded state.

[0106] In the transport position 4, the assembly comprises exactly two drawer levels 11, wherein generally, by further folding (or including the drawer sides 3), more than two drawer levels 11 are also conceivable. The drawer bottom 1 is arranged in two drawer levels 11 by means of the two drawer bottom sections 6, 7. Figure 2a and Figure 2b The drawer rear wall 2 and the drawer front wall 8 of the embodiment are arranged in only one drawer layer 11. One drawer layer 11 is formed by the drawer bottom 1 only.

[0107] The drawer layer 11 comprises two parts 13, 14 separated from one another by a gap 12, wherein the gap 12 is configured in the range of the material thickness of the drawer bottom 2 or less and allows for a suitable folding process despite the compact transport position. The longitudinal extension 15 of the first part 13 in the form of the drawer rear wall 2 (or the drawer front wall 8) is not equal to the longitudinal extension 15 of the second part 14 and is smaller than the longitudinal extension 15 of the second part 14 in the form of the second drawer bottom section 7 (or the second drawer bottom section 7 and the drawer front wall 8 arranged therein).

[0108] As can be seen in the enlarged detail section, the two components 13, 14 are connected to each other for positionally secure alignment with each other via a transport safety element 16. Generally speaking, the number or design of the transport safety elements 16 is arbitrary and can be present, for example, in the form of adhesive tape.

[0109] In the transport position 4 of the assembly, the two drawer levels 11 are in surface contact with one another, wherein preferably at least one drawer level 11 comprises two parts 13 , 14 , wherein the surface contact exists substantially over the entire longitudinal extension 15 of the first part 13 and the second part 14 .

[0110] The assembly comprises two drawer layers 11 , wherein the carrier layer 25 or the cover layer 26 or the adhesive layer 27 is arranged in the transport position 4 by being folded between the two drawer layers 11 facing one another.

[0111] Figure 2a An assembly according to another embodiment is shown, wherein the assembly comprises a drawer front wall 8, wherein the drawer front wall 8 is articulatedly connected to the second drawer bottom section 7 of the drawer bottom 1 for transferring the assembly from the transport position 4 into the use position 5. The drawer rear wall 2 comprises two drawer rear wall sections 9, which are articulatedly connected to one another.

[0112] Figure 2b and Figure 2a The only difference is that the assembly is in the transport position 4, in which the second drawer bottom section 7, the drawer rear wall 2 and the drawer front wall 8 are folded onto the first drawer bottom section 6 with surface contact over the entire longitudinal extension 15 of the second drawer bottom section 7, the drawer rear wall 2 and the drawer front wall 8. The free end 19 is spaced apart from the second free end 20 by a gap 12 in the order of magnitude of the material thickness of the drawer bottom 1, particularly preferably at most the material thickness of the drawer bottom 1.

[0113] Figure 3 A kit is shown consisting of an assembly according to the invention, two furniture fittings 29 in the form of rails, a drawer front wall 8 and two drawer side walls 3 .

[0114] Generally speaking, the kit may alternatively or additionally comprise furniture fittings 29 in the form of front wall brackets and / or rear wall brackets. Generally speaking, one of the side walls 3 may comprise a fixing element 31 (such as a furniture fitting) for fixing the drawer bottom 1 .

[0115] In the transport position 4 , the envelope of the assembly is of rectangular design, with all opposite side faces 28 (indicated by dashed lines) being designed to coincide with one another.

[0116] Figures 4a to 4d An assembly is shown in which the layer structure 24 comprises only two material layers. However, this is not absolutely necessary.

[0117] exist Figure 4a In the transport position 4 of the assembly, the free end 19 of the drawer rear wall 2 adjoins the other free end 20 of the drawer bottom 1 , wherein the other free end 20 can optionally be formed by the drawer front wall 8 .

[0118] As in Figure 4b As can be seen in the figure, the two drawer bottom sections 6, 7 as well as the drawer bottom 1 and the drawer rear wall 2 can be folded relative to each other. The adhesive for the film hinge 23 can be applied locally in the region of the hinged connection 21, 22 or flatly as a material layer of the layer structure 24.

[0119] The method for producing the assembly can be explained as follows: Two drawer bottom sections 6, 7 and a drawer rear wall 2 (and optionally also according to Figure 6a The drawer front wall 8 of the embodiment is provided by cutting a plate-shaped starting material, and the first drawer bottom section 6 is hingedly connected to the second drawer bottom section 7 and the drawer rear wall 2 via an adhesive layer 27 to form a film hinge 23. The drawer front wall 8 can be integrated similarly. Alternatively, it can also be arranged that the plate-shaped starting material is provided with an adhesive layer 27, and the plate-shaped starting material is cut in a partial area, so that the adhesive layer 27 in the form of a film hinge 23 hinges the first drawer bottom section 6 with the second drawer bottom section 7 and the drawer rear wall 2. The drawer front wall 8 can be integrated similarly.

[0120] exist Figure 4c In FIG. 5 , the assembly is in the use position 5 , in which the two drawer bottom sections 6 , 7 have different longitudinal extensions 15 .

[0121] from Figure 4c Set off, Figure 4d A further assembly step for producing a drawer 32 is shown, in which two drawer side walls 3 are connected to the drawer rear wall 2 and to the two drawer bottoms 6 , 7 .

[0122] The drawer side walls 3 are arranged outside the module, so that it is also conceivable to integrate at least one of the drawer side walls 3 via an articulated connection 21 , such as a film hinge 23 , in the transport position 4 of the module.

[0123] Figure 5a and Figure 5b The connection of at least one of the two drawer bottoms 6, 7 to at least one of the drawer side walls 3 via a fastening element 31 of the drawer side wall 3 is illustrated. The fastening element 31 is designed as a clamping connection to the drawer bottom 1, but can generally also be designed in the form of a furniture fitting 29.

[0124] exist Figure 5b In the embodiment, the drawer bottom 1 is already arranged on the drawer side wall 3 , wherein the clamped assembly prevents an undesired ejection of the drawer bottom 1 by means of a force fit of the fastening element 31 on the surface of the drawer bottom 1 .

[0125] Figure 6aThe assembly is shown in the transport position 4, in which the drawer rear wall 2 is supplemented by a drawer front wall 8. The drawer front wall 8 forms a third drawer level 11, wherein the drawer front wall 8 can generally alternatively also be arranged together with the second drawer bottom section 7 in the second drawer level 11. Generally speaking, the drawer front wall 8 can be connected to other panel components via a film hinge 23 (for example, it is conceivable to pivot through 270° between the transport position 4 and the use position 5) or placed on other panel components without connection, so as to be fixed separately, for example, to the drawer side wall 3.

[0126] Figure 6b shows a partially expanded state of the assembly, where Figure 6c The assembly is shown integrated inside the drawer 32. Since the drawer front wall 8 is already articulated to the second drawer bottom section 7 in the transport position 4, the drawer front wall 8 does not need to be positioned relative to the drawer bottom 1 or the drawer side walls 3 outside the unfolded state.

[0127] The drawer front wall 8 and the drawer rear wall 2 are connected to the drawer side walls 3 via furniture fittings 29 (two rear wall brackets and two front fittings).

[0128] The drawer 32 comprises an assembly in the operating position 5, wherein the drawer bottom 1, the drawer rear wall 2 and the drawer front wall 8 (generally formed, if appropriate, from a plurality of drawer front wall sections 10) are fastened to the drawer side walls 3 via furniture fittings 29. The material of the drawer side walls 3 is generally arbitrary, wherein the frame can be constructed in one piece or in multiple pieces.

[0129] The method for installing a drawer 32 can be explained as follows: The assembly is provided in a transport position 4, wherein the second drawer bottom section 7 and the drawer rear wall 2 are folded onto the first drawer bottom section 6 in surface contact over the entire longitudinal extension 15 of the second drawer bottom section 7 and the drawer rear wall 2. The assembly is transferred from the transport position 4 into a use position 5, wherein the drawer rear wall 2 (and the drawer front wall 8) are unfolded 90 degrees relative to the first drawer bottom section 6, and the second drawer bottom section 7 is unfolded 180 degrees relative to the first drawer bottom section 6. The drawer bottom 1, the drawer rear wall 2, and the drawer front wall 8 are arranged on the drawer side walls 3 by means of fasteners 31 (such as furniture fittings 29, such as front fittings and rear wall brackets).

[0130] Here as in Figure 2b or Figure 6a As in the transport position 4 , the drawer front wall 8 can be connected to the second drawer bottom section 7 .

[0131] Figure 7a An arrangement is shown in which both the drawer rear wall 2 and the drawer bottom 1 are formed from a plurality of segments. The drawer bottom has here more than five segments which have the same longitudinal extension 15 (but this is not absolutely necessary).

[0132] exist Figure 7b It can be seen that according to Figure 7a The components can be rolled up for transport.

[0133] exist Figure 7c It can be seen that according to Figure 7a The components can also be folded into a drawer layer 11 for transportation, Figure 7b In contrast, the drawer levels 11 are oriented parallel to one another.

[0134] As a basis for Figure 7b and Figure 7c The transport securing element 16 of the embodiment of the transport position 4 can be provided, for example, with a flexible belt such as a rubber band or a foil. The different longitudinal extensions of the drawer 32 can be flexibly adjusted by varying the number of segments or the size of the segments.

[0135] Figure 8 The drawer rear wall 2 is shown connected to the side wall 3 in the assembly's usage position 5 via a furniture fitting 29 in the form of a rear wall bracket. The drawer rear wall 2 can be clipped into the furniture fitting 29 and, alternatively or additionally, can be fixed in a secure position relative to the side wall 3 using fasteners 31 (e.g., screws).

[0136] Figure 9a It is explained that there are many different options, such as the film hinge 23 can be configured as a first hinge connection 21 or a second hinge connection 22. The following aspects can alternatively or additionally apply to a specific drawer bottom 1 and / or a specific drawer rear wall 2 and / or drawer front wall 8.

[0137] As can be seen in the upper left schematic diagram, the film hinge 23 can extend only partially over the material thickness of the drawer bottom 1, the drawer rear wall 2 or the drawer front wall 8, or can be arranged partially on the drawer layer 11. However, the film hinge 23 preferably extends over the entire material thickness, as can be seen in the lower left schematic diagram.

[0138] Since the drawer bottom 1 is preferably partially embedded in the drawer side wall 3, or the drawer rear wall 2 is partially arranged in the furniture fitting 29, for tight placement, the film hinge 23 preferably extends only partially across the width of the drawer bottom 1 and / or drawer rear wall 2 (orthogonal to the longitudinal extension 15 and the material thickness).

[0139] The number of material layers in layer structure 24 is also arbitrary, as can be seen in the two schematic diagrams on the left. For example, layer structure 24 can consist solely of carrier layer 25, supplemented by a decorative layer 26, and / or alternatively or additionally, an adhesive layer 27. Preferably, however, layer structure 24 is designed without an adhesive layer, wherein in transport position 4, adhesive layer 27 is arranged on the end face (i.e., in the area of ​​the adjacent hinged connections 21, 22 arranged for docking in use position 5, see the lower right schematic diagram) or on the exterior of the end face (as can be seen in the two schematic diagrams on the left). In use position 5, adhesive layer 27 is arranged in two layers between drawer bottoms 6 and 7.

[0140] However, the film hinge 23 can also be arranged between the drawer layers 11 and / or form an adhesive layer 27 of the layer structure 24, wherein the adhesive layer 27 preferably forms a layer of the layer structure 24 only in certain areas, as can be seen in the upper middle schematic diagram. However, it is also conceivable that the adhesive layer 27 extends across the entire longitudinal extension 15 of the drawer bottom 1 and / or the drawer rear wall 2.

[0141] In order to prevent the film hinge 23 from forming a bulge in the folded state of the film hinge 23 (especially in the transport position 4), the drawer bottom 1 and / or the drawer rear wall 2 (or the drawer front wall 8 or the drawer side walls 3) can include end bevels (see the upper right schematic diagram) and / or recesses in the material thickness (see the lower middle schematic diagram). Bulge formation could undesirably prevent the surface contact of the drawer layers 11.

[0142] As can be seen from the schematic diagram at the bottom right, the carrier layer 25 or the cover layer 26 together with the film hinge 23 preferably form a substantially flat surface (without projections of ridges or recesses caused by folding) in the use position 5. If necessary, a recess can be provided for this purpose. Generally, T-shaped, V-shaped, or I-shaped film hinges 23 are possible, for example.

[0143] It is particularly preferred to arrange the film hinge 23 on the outside at the end in the transport position 4 as shown in the left diagram and in the use position 5 as shown in the lower right diagram. In this case, in the transport position 4, surface contact can be generated between the components or sections without elastic deformation of the drawer layer 11.

[0144] Figures 9b to 9fOther possible variants of the film hinge 23 as the first hinged connection 21 or the second hinged connection 22, as well as designs with closed edges, are shown. Alternative designs of the first and second drawer bottom sections 6, 7, or similarly, the drawer rear wall 2, such as other chamfers or contour shapes, are also conceivable. The first and / or second drawer bottom sections 6, 7 can be replaced by the drawer rear wall 2, wherein generally, another cover layer 26 can be provided or omitted. The thickness of the components is generally arbitrary, with particular preference being given to suitability for the drawer bottom section 1 and the drawer rear wall 2. Features of the hinged connection of one embodiment can be used in other embodiments.

[0145] These embodiments are distinguished by the fact that, in combination with the individual aspects, the film hinge 23 can be arranged on an inclined surface 33, which is arranged as a depression 34 or with a step 35 or tongue and groove 36 on at least one drawer bottom section 6, 7 or the drawer rear wall 2. Furthermore, a covering 37 in the form of adhesive, foil, and profile is shown, which serves to cover an edge surface 38, optionally via a retaining device 39 of the drawer bottom 1 or the drawer rear wall 2.

[0146] Figure 9b The drawer bottom 1 is shown in different folding configurations by means of a film hinge 23 in the transport position 4 (left) or in the usage position 5 (right). Starting from the uppermost diagram, the following folding variants are involved:

[0147] Folding by means of an adhesive hinge, which is arranged on the rear side of the plate part. This is a particularly cost-effective connection option.

[0148] Folding is performed using a hot-melt adhesive hinge, which is arranged on the end face of the panel element. This embodiment is particularly cost-effective and simple to manufacture, as precise contouring of the abutment surfaces is unnecessary and a common separating cut is sufficient for this embodiment. Alternatively, a zigzag glue line and / or adhesive tape can be used to ensure the hinge function.

[0149] A fold similar to the previous embodiment, wherein the end faces or the butt edge faces are designed to be inclined (inclined face 33) in order to improve the mutual support of the panel parts, for example, in the event of a weight load on the drawer bottom 1, thereby reducing the load on the film hinge 23.

[0150] - A fold similar to the previous embodiment, with shoulders (steps 35) oriented orthogonally to the plane of the plate part in the area of ​​the upper side of the plate part arranged parallel to one another in the unfolded state, so as to produce an adhesive seam with reduced thickness in the unfolded state, which creates a particularly aesthetic impression in the use state.

[0151] - Folding by means of a hot melt adhesive hinge, which is arranged at the inclined edge face (inclined face 33) of the plate part. In addition, a groove can be introduced from the visible side and / or in the region of the cover layer 26, which groove is filled with further hot melt adhesive, especially in color coordinated with the cover layer 26, thereby achieving a more visually appealing appearance for the user.

[0152] Folding is performed using a hot melt adhesive hinge, which is arranged at the end on the inclined edge surface of the panel element. An additional tongue-and-groove profile 36 (formed by a web and a correspondingly configured recess) is provided, which locks the panel elements relative to each other perpendicularly to the panel element plane. This reduces the load on the film hinge 23, for example when the drawer bottom 1 is loaded by weight, thereby increasing the service life of the drawer bottom 1.

[0153] Figure 9c The two upper figures show different foldings of the drawer bottom 1 by means of the film hinge 23. The three lower figures show different foldings by means of the film hinge 23 for the connection between the drawer bottom 1 and the drawer rear wall 2.

[0154] Starting from the diagram at the top, the following folding scheme is involved:

[0155] - Folding is performed by means of a hot melt hinge, which is arranged at the end on the inclined edge surface (inclined surface 33) of the panel part, wherein a tongue and groove formation 36 is provided for stabilizing the panel parts relative to each other in the unfolded state. The tongue and groove 36 is formed by a lip arranged at the bottom that is bent over and overcome when the panel part is folded.

[0156] A folding similar to the previous embodiment, wherein the stabilization of the sheet metal parts relative to one another is ensured by a mechanical locking on the side facing away from the cover layer 26. This effectively prevents an undesired loosening of the folded connection.

[0157] - Folding by means of adhesive hinges, which are arranged at the edge faces / joint faces of the panel parts and at the adjoining rear sides of the panel parts. Alternatively, adhesive tape can be used to cover only the edge faces / joint faces. This embodiment is a particularly economical solution.

[0158] - Folding by means of a hot melt adhesive hinge, which is arranged at the inclined abutment surface (inclined surface 33) of the sheet metal part. In general, it is possible to introduce a groove on the visible side and / or on the cover layer 26, which is filled with further hot melt adhesive, especially in color, adapted to the cover layer 26, thereby creating a visually appealing folded connection.

[0159] - Folding by means of hot melt hinges, which are arranged at the abutment or edge faces of the drawer rear wall 2 and at the end region of the drawer bottom 1. The resulting additional adhesion surface behind the adhesive surface allows for additional stabilization of the panel.

[0160] Figure 9d Different folding of the drawer bottom 1 and the drawer rear wall 2 by means of film hinges 23 are shown.

[0161] Starting from the diagram at the top, the following folding scheme is involved:

[0162] - Folding by means of a hot melt adhesive hinge (similar to the previously described embodiment), wherein, in addition to an orthogonal orientation relative to the plate plane, the edge faces or the butt surfaces each have an inclined surface 33, thereby facilitating the creation of the folding connection and, in particular, allowing the two plate parts to be simultaneously shaped using a milling tool while being stacked together.

[0163] - A folding similar to the previous embodiment, wherein a recess 34 is provided in the edge region of the drawer bottom 1 for engaging the drawer rear wall 2 (in the region of the inclined surface 33). As a result, in the unfolded state, in particular in the event of loads in the direction of the rear side of the drawer 32 of the drawer rear wall 2 (for example, caused by objects sliding during the opening and / or closing process of the drawer 32), an increased stability of the panel parts relative to each other is achieved.

[0164] A folding similar to the previous embodiment, wherein in addition a shoulder in the form of a step 35 is provided at the end face of the plate part of the drawer rear wall 2, which engages in a corresponding recess in a recess arranged at the end face of the drawer bottom 1. This allows the plate part to be locked in the folded-out (or unfolded) state and prevents unintentional loosening of the folding connection, particularly during installation of the drawer 32.

[0165] Figure 9e Different embodiments of the edge or end-face closing of the edge face 38 by means of a cover 37 of the drawer rear wall 2 or of the drawer bottom 1 are shown.

[0166] These embodiments relate to the following closure concepts: A wood panel (generally, a board) is shown in the upper left corner with a double-sided coating (generally, only one-sided coating can be provided, or coating can be omitted entirely), wherein the edge surface 38 or end surface is provided with a colorant as a covering element 37. The colorant can be, for example, a paint, ink, lacquer, stain, colored hot melt adhesive, etc. The edge surface 38 can be designed to be orthogonal, angled, beveled, curved, rounded, etc., and / or have a contoured shape. Furthermore, as an alternative or supplementary embodiment, the wood panel can be shown with an edge strip arranged on the edge surface 38 as a covering element 37. The edge strip can be applied with the aid of an adhesive or directly molded.

[0167] On the right side, a wood panel with a rounded geometry is shown, with a foil applied on one side as a covering 37, which is pulled over the edge surface 38 of the drawer rear wall 2 or the drawer bottom 1 and covers the end area of ​​the panel. The visible rounding can generally also be shaped in the form of a bevel, a ridge or a bevel. For example, when the edge surface 38 is angled, the foil can extend only in the area of ​​the edge surface 38. In addition, a wood panel can be seen, which is coated on one side and a separate profile is arranged as a covering 37 at the edge surface 38 (for example, of the drawer rear wall 2) (located on the top), which is held clamped or fixed by an adhesive as a holding device 39.

[0168] At the bottom left, a timber panel with one-sided coating is shown, wherein a groove is provided on the edge face 38, into which a profile as a covering element 37 engages and is held by a pine cone-shaped connector as a retaining device 39. Furthermore, a timber panel is shown which comprises a dovetail-shaped profile on the edge face 38 as a retaining device 39, which is surrounded by the covering element 37 in the form of a U-shaped profile.

[0169] The method for applying the coating to the edge surface 38 (end surface or also the butt surface) is generally arbitrary, wherein it has proven to be particularly advantageous to seal the edge surface 38 (pointed, trapezoidal, rounded, rounded, etc.) by applying a paint by means of roller coating, spraying and / or vacuum technology, applying an adhesive or liquid plastic by means of roller coating (such as hot coating) or spraying, and applying a thermal transfer foil by means of a thermal transfer roller or thermal transfer belt.

[0170] When applying, for example, by vacuum painting, a loss-free and overspray-free multi-dimensional coating is achieved, wherein undercuts in particular can be coated with high quality, and coating materials such as solvent-free systems, water-based lacquers, UV lacquers or oils can be used.

[0171] In the painting method by roller coating, the coating medium can be applied in direct contact by a rubber roller (e.g., with EPDM, PUR, Hypalon, sponge rubber, etc.), as may be the case with a metering roller or a scoop for conveying the material. Metal rollers in the form of steel rollers, chrome-plated rollers, or the like can also be used. The amount of coating can be adjusted by the pressure and speed of the rollers and the viscosity of the coating material. In the case of a transfer wheel, the material is applied directly to the surface to be coated by a rotating disk, wherein the transfer wheel is adapted to the geometry of the medium to be applied. In the case of spray application, the material is deposited directly on the medium by means of static droplets. Alternatively, the droplets can be atomized by means of compressed air in order to apply a finer layer. In the casting method, the coating medium is poured onto the substrate by a casting head, wherein the amount of application can be limited by the gap opening and feed speed of the casting head.

[0172] In general, the following materials can be mentioned as coating media (especially for film hinges 23 or edge surface sealing), but they are not exhaustive: aqueous dispersion adhesive / lacquer systems, UV emulsions (aqueous), UV water-based lacquer systems, UV systems (radiation curing with the aid of LED / mercury emitters, doped emitters - for example Ga, Fe), PUR systems (hot melt adhesives, heat curing, 2K systems), polyester systems, epoxy systems, SH lacquer systems, powder coatings, etc.

[0173] Figure 9f The upper figure shows a wooden panel with a lacquer coating on both sides, wherein the edge face 38 (in particular of the drawer rear wall 2) is provided with a hinge profile as a cover 37, which is milled from the board and can be hinged by means of a film hinge 23. The film hinge 23 can be implemented by means of hot melt adhesive. To secure the hinge profile, an additional adhesive can be provided as a retaining device 39, with which the hinge profile is fixed on the side opposite the film hinge 23.

[0174] In the lower illustration, a wood panel is provided with a coating foil on one side, wherein the edge surface 38 is covered with a double-turn profile as a cover 37, which can be milled from the panel and has a double-turn profile protrusion. The double-turn profile protrusion can be swiveled 180° and results in a doubling of the preferred portion of the drawer rear wall 2 (on its rear side relative to the drawer 32). This increases the bending stiffness of the panel. The film hinge 23 can be in the form of a hot melt adhesive, wherein additional fixing by an adhesive as a retaining device 39 can be provided to additionally increase the stability of the panel. Alternatively or additionally, it is conceivable to implement the film hinge 23 as a coating foil in the form of a cover 37, wherein an additional adhesive can optionally be used as a lateral retaining device 39.

[0175] The present invention is not limited to wood panels. For example, plastic panels, metal panels, etc. can also be used.

[0176] Generally, a flat cover can be provided without adhesive on the narrow edges. Generally, the cover material can be placed on the narrow edges. The layer structure 24 of the sheet material is generally arbitrary. For example, the film hinge 23 can be in the form of a coating and / or a flexible foil.

[0177] For example, the drawer front wall 8 can be realized in such a way that fixing means are pre-mounted on the drawer side walls 3 , which enable positionally secure fixing of the drawer front wall 8 during folding from the transport position 4 into the use position 5 .
