The disclosure, moreover, relates to a cabinet, in particular a kitchen cabinet base unit, comprising a prefabricated installation unit and / or a system that is inserted into and fixed to the kitchen cabinet base unit. Although the present disclosure is generally applicable to any cabinet, the present disclosure is elucidated in relation to kitchen cabinet base units.2. Description of Related Art

[0003] In kitchen cabinet base units, in particular in the region of the sink, the installation space is extremely limited due to the supply lines and drain pipes of the sink that need to be arranged for this purpose. Since individual constraints, such as the width, depth, and height of the kitchen cabinet base unit, which can also be changed by a user at short notice, often need to be taken into account, it has become common practice to fix individual equipment elements, such as an extractible waste bin, directly to the cabinet base unit or its movable front panel, for example, to a door. The individual equipment elements exhibit a wide range of dimensions and are fixed directly by an installer on site in the cabinet base unit at a position that suits him, which requires an extremely high level of assembly work in terms of time and complexity.

[0004] US 2021 / 0198880 A1 discloses a kitchen cabinet with an upper region and a lower region. In one embodiment example, the upper region comprises a sink, a faucet, a water filter assembly, a water inlet connection and a power connection. In another embodiment example, the lower region comprises a first extractable drawer and a second extractable drawer, wherein the first extractable drawer and the second extractable drawer are configured to receive one or more components of the upper part.

[0120] FIG. 4 shows a part of a prefabricated installation unit according to an embodiment of the present disclosure in a three-dimensional view from an oblique rear view.

[0121] FIG. 4 substantially shows a section of the rear side of the installation unit 1 in the lower region. The installation unit 1 comprises a plurality of steps 19a, 19b so that horizontal portions and vertical portions alternate overall. Small electrical devices, cable guides or the like can, by way of example, be arranged in the horizontal portions. In this way, in FIG. 4, a pull-out support system 22 is, for example, arranged on the vertical lower step 19a, which is triggered when light pressure is applied to the waste container 8 in the direction of the pull-out support system 22 and then pushes the waste container 8 forward by means of a rotatable arm 23. In this way, no handles, for example, on a kitchen front panel, are necessary if these are connected to the waste container 8 and / or its pull-out 7. Alternative to the waste container 8, another extractible element such as a drawer can be arranged. When light pressure is applied to the drawer in the direction of the pull-out support system 22, the drawer is triggered and the pull-out support system 22 then pushes the drawer forward by means of the rotatable arm 23. In this case, the power supply that is necessary for the pull-out support system 22 can then be provided, for example, by fixing a socket to the mounting frame 15.

[0122] The vertical portions can have an opening 20 as shown in FIG. 4, which enables access to built-in components of the installation unit 1.

[0123] In a further embodiment, which is not shown, the horizontal dividing wall 4 can not be configured flat in the rear region 18, but rather is configured with an additional step in the upwards vertical direction. This enables improved accessibility in the rear region 18. At the same time, the stability of the installation unit 1 can also be improved.

[0124] FIG. 5 shows a piece of furniture with an installation system and FIG. 6 shows the piece of furniture of FIG. 5 in detail and in front view with additional elements.

[0125] FIG. 5 shows the rear view of a piece of furniture in the form of a kitchen cabinet base unit 2A. The cabinet base unit 2A has a recess or opening 3A, which is usually used to be able to connect a sink to hot and cold water connections in a house wall. In the recess 3A, two identically configured installation elements 1A are arranged on the sides, to which two crossbars 7aA, 7bA, arranged at different (vertical) heights, extend, which crossbars are connected to the two installation elements 1A at the ends. The installation elements 1A can, however, also be arranged, as required, at the top and / or bottom in the recess 3A of the piece of furniture. The installation elements 1A respectively have mirror symmetry along an axis 17A, that is horizontal here.

[0126] An installation element 1A, as shown in FIG. 5, exhibits a substantially L-shaped cross-section. The shorter leg is formed by a fixing region 4A (see FIG. 6), the longer leg by an installation region 5A. Projections 14A are arranged in the extension of the installation region 5A in its plane of extension, which projections serve as stops for the correct positioning of the installation element 1A in the recess 3A of the cabinet base unit 2A. The installation element 1A is usually mounted from the front. To do this, the installation element 1A is inserted into the opening 3A and the stops 14A are pushed laterally between the house wall (not shown) and the rear wall 25A of the cabinet base unit 2A. The fixing region 4A is then pressed against the interior wall 26A of the cabinet base unit 2A and fixed there, for example, by screwing, gluing, clipping or the like.

[0127] Over the entire region or surface 8A, in the installation region 5A of the installation element 1A, there is a grid 10A with a plurality of rows 11A (see FIG. 6) of double-keyhole-shaped recesses 9A. Neighboring rows 11aA, 11bA of the recesses 9A are shifted by half a distance, here a vertical distance 12A, between two recesses 9A of a row 11aA. The horizontal distance 13A, between two recesses 9A, 9aA at the same horizontal level in rows 11aA, 11cA, corresponds to the vertical distance 12A. The installation element 1A thus comprises a perforated grid, the distances of which are chosen so that a fixed grid size results in the vertical and horizontal direction according to FIG. 5. In addition, the offset by half of the distance in the horizontal and vertical directions of the grid 10A results in an intermediate grid, which enables a finer positioning and fixing of additional elements on the installation element 1A.

[0128] The same grid dimension is configured for the crossbars 7aA, 7bA. Overall, the grid 10A is chosen so that it continues in a horizontal and vertical direction over the respective crossbar 7aA, 7bA, when a crossbar 7aA, 7bA is detachably fixed to, in particular hooked into, the two installation elements 1A. The recesses 9A of the crossbars 7aA, 7bA are keyhole-shaped. The crossbars 7aA, 7bA respectively exhibit mirror symmetry along a vertical axis 17aA.

[0129] A rounded, substantially rectangular opening 16A is arranged in the center of the respective installation region 5A. As regards the cross-sectional surface, the rectangular opening is significantly larger than the cross-sectional surface of the recesses 9A, in particular more than twice as large, and is used to feed through hoses, cables or the like.

[0130] In FIG. 5, the two installation elements 1A are configured as identical parts. In a further embodiment not shown here, these installation elements 1A can also be different in terms of their width, which is to say, their horizontal extent. In this way, for example, one installation element 1A can comprise fewer rows 11A than the other installation element 1A. In particular, one installation element 1A can comprise only one row 11A and the other installation element can comprise at least four rows 11A, in particular six rows 11A. A possible crossbar 7aA, 7bA between the two installation elements 1A is then made correspondingly longer.

[0131] Different additional elements 6aA, 6bA are also shown in FIG. 6. As shown in FIG. 6, the rear wall of the additional element 6a is used to hook into a connecting element (not shown here) in at least one recess 9A of the crossbar 7aA or of the installation element 1A, and is optionally also secured there. The additional element 6aA is configured to guide cables, which can be fixed to the respective additional element 6aA by clamping. As shown in FIG. 6, the rear wall of the additional element 6bA is hooked into a connecting element (not shown here) in at least one recess 9A of the crossbar 7aA, and optionally also secured there. The additional element 6bA comprises a backet 20A for securing pipes 21A such as drainpipes or the like.

[0132] FIG. 7 shows an installation system.

[0133] FIG. 7 substantially shows an installation system 100A according to FIG. 5 and FIG. 6. In contrast to the installation system 100A according to FIG. 5 and FIG. 6, the installation system 100A according to FIG. 7 has no opening 16A in the respective installation element 1A. The laterally protruding projections 14A are also missing. In their stead, on the installation elements 1A of FIG. 7, vertical projections 15A are now arranged on the fixing region 4A. These vertical projections are arranged in a plane in front of the plane of the installation region 5A and enable the installation element 1A to be mounted directly from the front into the recess 3A of the cabinet base unit 2A by means of the stops on a front side of the rear wall of the cabinet base unit 2A. The fixing region 4A and installation region 5A are, moreover, additionally connected to each other at the front by means of reinforcements 19A. The crossbars 7aA, 7bA are, moreover, configured to respectively be taller and wider, and thus comprise more rows of recesses 9A, and in the embodiment of FIG. 7, they are not only mirror-symmetrical along a vertical axis 17aA, but also with respect to a horizontal axis 17bA.

[0134] FIG. 8 shows an additional element fixed to an extension element of an installation system.

[0135] An additional element 6A is shown in FIG. 8, which additional element has a clamping device 20A for accommodating a hose 22A.
