Description

[0001] The present invention relates to a cabinet comprising at least two side walls and a rear wall arranged between the two side walls, a cabinet system consisting of several of these cabinets, and an arrangement with a built-in cabinet system. The invention also relates to a method for assembling this cabinet or cabinet system.

[0002] It is common practice to place individual cabinets side by side to create a cabinet system or wall unit. Each individual cabinet essentially consists of two spaced-apart side panels connected by top and bottom panels positioned transversely to the side panels. A back panel, attached to the side panels, top panel, and bottom panel, closes the cabinet body. The top and bottom panels are detachably connected to the side panels via connectors. The back panel, preferably attached to the outside and often screwed or nailed in place, stiffens the cabinet body. Thus, each cabinet body is an independent cabinet with two side panels. Doors, particularly hinged or sliding doors, can be provided at the front, and shelves, clothes rails, hooks, or drawers can be added inside.The individual cabinets serve to store clothing, shoes, or other items, which can be placed lying down or hanging inside. Such cabinets or cabinet systems can be designed as built-in cabinets with a front panel installed between the floor and ceiling, or as freestanding cabinets. During installation, it may be necessary to assemble the cabinet upright, as the room height may be insufficient for horizontal installation. Furthermore, each cabinet must be individually aligned before being connected to form the cabinet system.

[0003] German utility model DE 1 868 432 U discloses a cabinet system consisting of two or four individual cabinets arranged side by side, wherein two adjacent cabinets share a common side wall with the associated saving of material.

[0004] Based on this prior art, the present invention aims to provide a cabinet, a cabinet system therefrom, an arrangement with the cabinet system and a method for assembling it, which are characterized by simple assembly.

[0005] This problem is solved by a cabinet with the features of claim 1, a cabinet system with the features of claim 10, an arrangement with the features of claim 12, and a method with the features of claim 13. Advantageous embodiments of the invention are described in claims 2 to 9, 11, 14, and 15.

[0006] According to the invention, a cabinet comprising at least two side walls and a rear wall arranged between the two side walls achieves simplified assembly by making the rear wall movable relative to the two side walls. This allows the vertical alignment of the side walls to be decoupled from the rear wall. The vertically movable rear wall permits vertical alignment of the side walls without hindering this alignment through attachment to the side walls and consequently creating tension in the cabinet. A base and a top section, which are attached between the side walls, as well as any other components of the cabinet, are also not connected to the rear wall. This cabinet can also be large enough to extend from the floor to almost the ceiling at a given installation location.The cabinets cannot be installed fully assembled there because the diagonal of the cabinet is longer than the room height. The cabinet must be mounted vertically.

[0007] A key advantage is that the back panel can be moved up and down. This makes it easy to place the resulting cabinet on an uneven floor and then adjust it vertically.

[0008] It is also advantageous that the back panel and the two side panels rest on a floor, preferably directly. This ensures a stable intermediate state even during the assembly of one side panel and the back panel, enabling single-person assembly.

[0009] According to the invention, a groove is provided in or on each of the two side walls, into which the back wall is inserted with its lateral edge. This arrangement of the grooves for the inserted back wall is an independent inventive idea, since even one side wall with an inserted back wall is very stable. This creates a stable angle that rests on the floor. The cabinet can therefore be assembled by a single person. When the second side wall is inserted onto the back wall, the resulting U-shape further increases the stability of the intermediate cabinet. The grooves are preferably arranged as slots in the side walls, but can also be attached to the back of the side wall using appropriate profiles. Ultimately, it is important that the side wall and back wall are adjustable relative to each other.This height adjustability is maintained at least during an intermediate assembly stage, such as when the base and lid sections are mounted between the side walls. The back wall is also height-adjustable relative to the base and lid sections, and therefore can be moved past them.

[0010] The design is particularly simple in that, at least in one intermediate assembly stage, the two side panels can each be placed on the floor using height adjusters and adjusted in height, preferably relative to the back panel. This facilitates the vertical alignment of the side panels, even by a single person.

[0011] Furthermore, the design is particularly simple: the back panel rests on the floor using feet, specifically adjustable height mechanisms. This allows the back panel to be easily gripped from below at its lower edge between the feet, which only cover a small portion of the lower edge, when inserting it into the groove of the side panel.

[0012] It is advantageous that the back panel has a length greater than the length of a side panel. The length of the back panel is at least equal to the possible adjustment range of the height adjusters. This ensures that the back panel extends beyond and downwards over both the top and bottom sections, and that the interior of the cabinet remains closed by the back panel even when its height is adjusted.

[0013] To further simplify assembly, a fastening element is provided on the rear side of each side panel, to which a mounting strap can be attached, at least temporarily, connecting the side panels together. Advantageously, the mounting strap is elastic and / or the fastening elements are tacks, prongs, rivets, pins, or nails. The mounting strap, attached to the fastening elements, holds the side panels against each other and thus secures the rear panel in the grooves. Preferably, the mounting strap is speared onto the prongs.

[0014] With regard to a cabinet system assembled from a cabinet with at least two cabinets arranged side by side, it is advantageously provided that adjacent cabinets share a common inner side panel. The resulting cabinet system thus has a modular structure. It is advantageously provided that the width of an inner side panel is, in particular, exactly twice the width of an outer side panel. The outer side panel is preferably no less than 18 mm and no more than 19 mm thick. The inner side panel has a material thickness of 36 mm to 38 mm. This ensures that all doors or fronts of each cabinet in a cabinet system can have the same width and that standard hinges can be used. Doors or fronts from a different cabinet system can also be used with individual cabinets of the same cabinet dimensions placed side by side.The entire cabinet system can also be set up on uneven floors, with each side wall being individually aligned in terms of its height.

[0015] The invention also relates to an arrangement with a previously described cabinet system, in which the cabinet system is advantageously installed in a wall niche with side and opposite walls, a front panel is arranged between the walls and the cabinet system, and the front panel is detachably attached to the cabinet system from within. This arrangement makes it possible to provide a precisely fitting built-in cabinet even for changing locations. The individual components, such as outer side panels, top panels, and, if required, bottom panels, can therefore be separated from the front panel from the inside, and, with the exception of the top panel, all components, including the back panels, are joined together via plug-in connections.It is well known that built-in wardrobes are often left behind when moving house, as adapting them to a new location would incur costs similar to purchasing a new wardrobe. This entirely new design is therefore also ingeniously suited for renters, because, in the event of a move, the easily assembled built-in wardrobe can be just as easily disassembled and transported as a portable, non-built-in wardrobe. For this purpose, the front panel can simply be removed. At the new location, a new front panel is manufactured, and the wardrobe system, or part thereof, or an extension thereof, is reassembled.

[0016] According to the invention, a simplified assembly method for constructing a cabinet or a cabinet system is achieved through the following steps: erecting a first outer side panel, erecting and inserting a first back panel into a groove in the first outer side panel, erecting and inserting a second outer side panel or a second inner side panel with its groove onto an edge of the first back panel, attaching a mounting strap to a fastener on the first outer side panel, tensioning and attaching the mounting strap to a fastener on the second outer side panel or the second inner side panel, and repeating the preceding steps as necessary to construct further cabinets of the cabinet system. The grooves and the insertable back panel, in combination with the mounting strap, enable the cabinet or cabinet system to be assembled by a single person.

[0017] Aligning the height is particularly easy because the side walls can be aligned to a common height level by adjusting height adjusters on the side walls.

[0018] Basically, it is possible that either after aligning to a common height level or after tensioning and securing the mounting strap, a base part and a top part are attached between the side walls of each cabinet. The invention is described below with reference to the illustrations in a drawing.

[0019] Examples of implementation are discussed in more detail. They show: Figure 1 a top view of a state-of-the-art cabinet system with two adjacent cabinets; Figure 2 a top view of a cabinet system according to the invention with two adjacent cabinets; Figure 3 shows a rear view of a single cabinet from the cabinet system, Figure 4a rear view of a cabinet system in an intermediate assembly state; Figure 5 a front view of the cabinet system of Figure 4 in an aligned intermediate assembly state; Figure 6 A front view of a cabinet installed in a recessed niche in an intermediate assembly state.

[0020] The Figure 1Figure 1 shows a top view of a prior art cabinet system AB with two separate, adjoining first and second cabinets A and B. Each of the two cabinets A and B has a cabinet body with two opposing and spaced-apart side walls C, a back wall D, and a front wall E, all oriented vertically I3 and defining an interior space (not shown). The back walls D are attached from behind in rearward-facing recesses in the side walls C and, optionally, to a top panel H and a bottom panel (not shown). The front walls E are each designed as a door, with the doors pivotally attached to a side wall C by at least two hinges G. The inner side walls C of the two cabinets A and B are directly adjacent to each other.The interior of cabinets A and B is bounded at the top by the lid section H, which is attached to the side walls C by means of furniture connectors F. The interior spaces are also bounded on one underside (not shown) by the base section (not shown).

[0021] The Figure 2 Figure 1 shows a top view of a cabinet system 100 according to the invention, comprising a first cabinet 1a and a second cabinet 1b, which are arranged in a horizontal longitudinal direction I1. In the usual manner, the two cabinets 1a, 1b each define an interior space 3. The cabinet system 100 is thus designed for the modular arrangement of interior spaces 3. In the embodiment shown here, two interior spaces 3 are arranged in a row. However, the invention also relates to cabinet systems 100 with only one or more than two interior spaces 3. In the usual manner, each of the interior spaces 3 is defined by two side walls 2a, 2i, and a base section 5 (see Figure 1). Figure 5 ), a lid part 6 (see Figure 5 ) and a rear wall 4 and, if necessary, a front wall (not shown), in particular a sliding or revolving door.

[0022] The individual cabinets 1a, 1b each serve to store clothing, shoes, or other items, which can be placed lying down or hanging inside the cabinets 1a, 1b. Such cabinets 1a, 1b, or cabinet systems 100, can be designed as built-in cabinets with a front panel between a floor 10 and a ceiling, or as freestanding cabinets. During installation, it may be necessary to assemble each cabinet 1a, 1b upright, as the room height may be insufficient for horizontal installation or standing upright. The interior compartments 3 may contain, for example, shelves, clothes rails, hooks, or drawers.

[0023] The side walls 2a, 2i, the bottom parts 5, the lid parts 6, the back walls 4 and the front walls are each designed as flat panels with a rectangular or square cross-section and are often coated chipboard.

[0024] Compared to the one in Figure 1In contrast to the illustrated cabinet system AB with side walls C of a uniform width or thickness, the present cabinet system 100 with more than one interior space 3 is characterized by two outer side walls 2a with a width ba, which is approximately half the width of the inner side wall 2i with a width bi. The inner side wall 2i is arranged between the two interior spaces 3. No further interior spaces 3 adjoin the two outer side walls 2a in a corresponding manner. The inner side wall 2i has a width bi, in particular a material thickness of 36 mm to 38 mm. The width ba of the outer side wall 2a has in particular a material thickness of 18 mm to 19 mm.This results in an assembly advantage compared to individual cabinets A, B, since only one inner side wall 2i needs to be mounted, but at the same time the front walls E known from the individual cabinets A, B with their usual widths can be used without having to make any adjustments to the width or the hinges.

[0025] In the Figure 2 The cabinet system 100 is shown in an intermediate assembly state.

[0026] In the illustrated embodiment, the left outer side wall 2a is first erected as an example.

[0027] For the subsequent insertion of the rear wall 4 into the left outer side wall 2a, the inner and outer side walls 2a, 2i have, viewed in the horizontal transverse direction I2, at their respective rear ends, a groove 21 with a rectangular cross-section, which extends in the vertical direction I3 over the entire length l4 of the side wall 2a, 2i (see Figure 3) extends and preferably has a uniform depth throughout. The outer side walls 2a have a groove 21 only on their inner side, and the inner side walls 2i have a groove 21 on both sides. The cross-section of the groove 21 is selected such that the rear wall 4, with its edge 4a, can be inserted into the groove 21 in the insertion direction e, which runs parallel to the longitudinal direction l1, in a form-fitting manner but with slight play, while still being displaceable in the longitudinal direction of the groove 21 and thus in the vertical direction l3. Slight play is understood to be a few tenths of a millimeter, preferably 1 to 3 tenths of a millimeter. The rear wall 4 is no thinner than 10 mm and no thicker than 12 mm.

[0028] After the left outer side wall 2a is erected, the rear wall 4 is erected and its left edge 4a is inserted into the groove 21 of the left outer side wall 2a in an insertion direction e that runs in the longitudinal direction l1. Since the rear wall 4 is inserted into the groove 21 and the rear wall 4 and the left outer side wall 2a rest on a base 10, and since, viewed from above, the rear wall 4 and the left outer side wall 2a are aligned at right angles to each other, the rear wall 4 and the left outer side wall 2a stand independently on the base 10. The side wall 2a and the rear wall 4 form a stable angle.

[0029] In a further assembly step, the inner side wall 2i is erected and, in the insertion direction e, its left groove 21 is pushed onto the right edge 4a of the rear wall 4.

[0030] Once two side panels 2a, 2i and a back panel 4 have been erected and slid together, this resulting intermediate cabinet, which is already relatively stable, is further stabilized by a mounting strap 51 before a base section 5 and a top section 6 are installed and the side panels 2a, 2i are aligned vertically. The mounting strap 51 provides the intermediate cabinet, or rather the part of the first cabinet 1a, with sufficient stability in this unsecured intermediate assembly state to prevent the two side panels 2a, 2i and the back panel 4 from falling apart. The mounting strap 51 can be a cord or a narrow band, which can be elastic or rigid. For this purpose, a fastening element 52, such as a pin, nail, or prong, is attached in a first step to a narrow rear side 2r of the left outer side panel 2a, or it may already be attached before the side panels 2a, 2i are erected, or it may already be provided there.Viewed in the longitudinal direction of the side walls 2a, 2i, the fastening element 52 is arranged approximately in the middle of each side wall 2a, 2i, i.e., in a region of 40 to 60% of the length of the respective side wall 2a, 2i. A first end of the mounting strip 51 is attached to the fastening element 52, tensioned, and fastened to a second fastening element 52 on a narrow rear side 2r of the first inner side wall 2i. Preferably, the mounting strip 51 is elastic and is attached under tension. The attached mounting strip 51 pulls the two side walls 2a, 2i towards each other in or against the longitudinal direction l1, thereby pushing the edges 4a of the rear wall 4 into the respective groove 21 up to a groove base. The mounting strip 51 thus runs behind the rear wall 4 and essentially horizontally. This prevents the rear wall 4 from slipping out of the grooves 21 in the side walls 2a, 2i.Preferably, the mounting strap 51 is sufficiently long to also clamp further sub-cabinets of the cabinet system 100 to be erected. The purpose of the mounting strap 51 is to fix the side walls 2a, 2i and the rear wall 4 to each other, at least temporarily.

[0031] Now, the second cabinet 1b, or any further cabinets, are assembled in a similar manner and each is secured with the mounting strap 51. In this assembly process, all side panels 2a, 2i and rear panels 4 are first pushed together and positioned securely in their designated location.

[0032] With regard to the resulting intermediate cabinet, the side walls 2a and 2i are positioned parallel to each other and spaced apart in the longitudinal direction l1. Furthermore, the rear walls 4 are positioned perpendicular to the side walls 2, so that they extend in a transverse direction I2. The side walls 2 and the rear walls 4 are also oriented in the vertical direction I3. The vertical direction I3 extends perpendicular to the longitudinal direction l1 and perpendicular to the transverse direction I2.

[0033] The top part 6 and the bottom part 5 (not shown) are then permanently attached to each pair of adjacent side walls 2a, 2i, in particular by being inserted between them. The top part 6 and the bottom part 5 are attached to the side walls 2a, 2i by means of detachable connectors 7. In the usual manner, the top of the top part 6 is flush with the upper edge of the side walls 2a, 2i, and the bottom part 5 is flush with the lower edge of the side walls 2a, 2i. The top part 6 and the bottom part 5 are not attached to the rear wall 4 and are movable relative to the rear wall 4 in and against the vertical direction I3. The first cabinet 1a is then fixed with respect to the longitudinal direction l1 and the transverse direction I2. Since the side walls 2 and the rear wall 4 are placed on the floor 10, the cabinet 1a is also fixed in the vertical direction I3.In the vertical direction I3, the first cabinet 1a can now be finally aligned by maintaining a distance a (see . Figure 3 The height of the lower edge of the side walls 2a, 2i from the floor 10 is adjusted by means of height adjusters 8, in particular screw-in feet. The height adjusters 8 are attached to the lower edge of the side walls 2a, 2i. Since the top part 6 and the bottom part 5 are now fixedly attached to the side walls 2, they are also aligned, preferably into a horizontal position. Each side wall 2a, 2i can be aligned independently of the other side walls 2a, 2i of the cabinet system 100. Since the rear wall 4 rests on the floor 10, its height remains unchanged.

[0034] In the Figure 2 So far, only the left lid part 6 is complete. The right lid part is still missing.

[0035] In principle, it is also conceivable to align all or part of the side walls 2a, 2i of the cabinet system 100 vertically in the intermediate assembly state before installing the bottom and top parts 5, 6.

[0036] Additionally, in the Figure 2It is indicated that the cabinet system 100 is installed in a wall niche 60 with walls 63. Viewed from above, the wall niche 60 has at least two opposing and mostly parallel walls 63, which are connected to each other via a rear wall. A one- or multi-part front panel 61 is arranged between the walls 63 and a surrounding outer surface of the cabinet system 100, and thus along the outer side walls 2a, the top sections 6, and, if necessary, also the bottom sections 5. The panel-like front panel 61 is detachably connected to the cabinet system 100 from inside the cabinet system by screws 64.For this purpose, the front cladding is attached to profiles 62, preferably drywall profiles, via screws 64, and the profiles 62 rest on the outer side walls 2a, the cover parts 6 and, if necessary, also on the bottom parts 5, and are each attached to the cabinet system 100 from the interior spaces 3 of the cabinet system 100 via further screws 64.

[0037] The Figure 3Figure 1 shows a rear view of a single cabinet 1a of the cabinet system 100 in its intermediate assembly state, i.e., without the top and bottom panels 6, 5 installed, but with the mounting strip 51 attached. As previously described, the rear panel 4 is positioned between the two side panels 2a, 2i, or rather, inserted into their grooves 21. The side panels 2a, 2i and the rear panel 4 rest on the floor 10 and also extend vertically in the direction I3. Two feet 26 are arranged at the lower edge of the rear panel 4, creating a gap between the lower edge of the rear panel 4 and the floor 10. The feet 26 facilitate vertical alignment of the rear panel 4, as the lower edge of the rear panel 4 is accessible. These feet 26 can also be omitted. The feet 26 of the rear panel 4 are not height-adjustable.Due to a floor irregularity 12 shown here in the form of a slope, vertical alignment of the side walls 2a, 2i causes the lower edge 4b ​​of the rear wall 4, or the left foot 26, to lose contact with the floor 10. This can also cause the left inner side wall 2i, with its feet in the form of the height adjusters 8, to lift off the floor 10 if the lateral edge 4a of the rear wall 4 does not slide easily in the groove 21 of the inner side wall 2i but remains stuck in its inserted position. A leveling element 13 in the form of a wedge can be provided to be inserted below the left foot 26 and to hold the rear wall 4 in the vertically or horizontally aligned position. Subsequently, the height adjusters 8 of the left side wall 2i are to be extended or rotated towards the floor 10 to align the cabinet 1a vertically, independent of the level of the floor 10.

[0038] It is also conceivable that the rear wall 4 is aligned vertically and the left side wall 2i with its height adjuster 8 remains on the floor 10 and is only raised to a level with the right side wall 2a after the rear wall 4 has been aligned by adjusting the height adjuster 8.

[0039] In any case, it is evident that the back wall 4 and the side walls 2a, 2i can be adjusted independently of each other in height in order to align the cabinet 1a vertically.

[0040] For the installation of the cabinet 1a or the cabinet system 100 in a recess 14, two block-like spacers 9 are arranged on the outside of the already erected right outer side wall 2a, by which a minimum distance (not shown) of the cabinet 1 to a room wall of a wall recess can be ensured.

[0041] The rear wall 4 has a length l5, which is greater than the length l4 of the side walls 2a, 2i. The length l5 of the rear wall 4 is approximately the length l4 of the side walls 2 plus the maximum possible height adjustment of the side walls 2a, 2i by the height adjusters 8. Therefore, even a side wall 2 at its maximum height adjustment does not protrude beyond the rear wall 4. If a cover part 6 is attached to the side wall 2, no gap forms between the rear wall 4 and the cover part 6, even when the side wall 2a, 2i is at its maximum height adjustment.

[0042] The Figure 4 Shows a rear view of a cabinet system 100 with three cabinets 1a, 1b, 1c in an intermediate assembly state. The first cabinet 1a is attached according to... Figure 3Two further cabinets 1b, 1c have been added. The cabinet system 100 therefore comprises three modularly connected cabinets 1a, 1b, 1c. To add the further interior spaces 3, or cabinets 1b, 1c, a back panel 4 and a side panel 2a, 2i were alternately attached to the first cabinet 1a in the manner described above. The mounting strip 51 was attached to the rear surfaces 2r of the side panels 2a, 2i using the fasteners 52. The cabinet system 100 is placed on the floor 10, which has a slope 12. This results in height differences between the side panels 2a, 2i and the back panels 4. Furthermore, the lower edges 2u of the side panels 2 are not yet horizontally aligned using the height adjusters 8.

[0043] The Figure 5 shows a front view of the cabinet system 100 of the Figure 4In the aligned intermediate assembly state. It is evident that the cabinet system 100 is assembled and aligned. For alignment, the height adjusters 8 are adjusted according to the slope 12 of the floor 10. This ensures that the base sections 5 and the top sections 6 are horizontal.

[0044] It is evident that the back walls 4 placed on the floor 10 protrude beyond the lid parts 6 to different extents due to the different height compensation required for the side walls 2a, 2i caused by the slope 12.

[0045] The Figure 6Figure 1 shows a front view of a cabinet system 100 with three cabinets 1a, 1b, 1c, installed in a recess 14, in an intermediate assembly state. Here, the floor 10 has an unevenness 12 in the form of a depression. As a result, one side panel 2 positioned above the depression 12 is lower than the other side panels 2. Consequently, the bottom panels 5 and the top panels 6 are not horizontally aligned. This can be corrected by adjusting the height adjuster 8, which is located on the second inner side panel 2i positioned in the depression 12, so that the second inner side panel 2i is raised accordingly.

[0046] The spacers 9 attached to the left outer side wall 2a of the cabinet system 100 are used here to adjust a distance of the cabinet system 100 laterally to a wall of a built-in niche 14. Reference symbol list
