When the drawer is slightly pressed in the direction of the pull-out auxiliary system 22, the pull-out auxiliary system is triggered, and then the pull-out auxiliary system 22 pushes the drawer forward in the opposite direction by means of the rotatable arm 23. Here, the power supply required for the pull-out auxiliary system 22 can be carried out, for example, by fixing the socket to the mounting frame 15.

[0125] like Figure 4 As shown, the vertical section may include an opening 20 which enables access to mounting components of the mounting unit 1 .

[0126] In another embodiment not shown, the horizontal partition wall 4 is not designed to be flat in the rear region 18, but has an additional step in the vertical direction. This improves accessibility in the rear region 18. At the same time, the stability of the installation unit 1 can also be improved as a result.

[0127] Figure 5 A piece of furniture is shown with a mounting system, and Figure 6 Show Figure 5 Detail of a furniture piece and front view with additional elements.

[0128] exist Figure 5 , a rear view of a piece of furniture in the form of a kitchen cabinet 2A is shown. In the cabinet 2A there is a recess or opening 3A, which is usually used to be able to connect a flushing device to a hot water connection and a cold water connection in the wall of the house. In the recess 3A, two identically constructed mounting elements 1A are arranged laterally on the left and right sides, on which two crossbeams 7aA, 7bA arranged at different (vertical) heights extend, which are connected to the two mounting elements 1A at the end sides. However, the mounting elements 1A can also be arranged at the top and / or bottom in the recess 3A of the piece of furniture as required. The mounting elements 1A each have a mirror symmetry along the horizontal axis 17A.

[0129] like Figure 5 As shown, the mounting element 1A has a substantially L-shaped cross section. The shorter side passes through the fixing area 4A (see Figure 6), the longer side being formed by the mounting area 5A. In the extension of the mounting area 5A in its extension plane, a projection 14A is provided, which serves as a stop for correctly positioning the mounting element 1A in the recess 3A of the base cabinet 2A. The mounting element 1A is usually assembled from the front. For this purpose, the mounting element 1A is introduced into the opening 3A and the stop 14A is pushed laterally between the house wall (not shown) and the rear wall 25A of the base cabinet 2A. Subsequently, the fixing area 4A is pressed against the inner wall 26A of the base cabinet 2A and fixed there, for example, by screwing, bonding, clamping, etc.

[0130] The mounting element 1A has in its mounting region 5A a plurality of rows 11A with double keyhole-shaped recesses 9A over the entire region or surface 8A (see Figure 6 ) grid 10A. The recesses 9A of adjacent rows 11aA, 11bA are displaced by half a (here vertical) distance 12A between two recesses 9A in row 11aA. Here, the horizontal distance 13A between two recesses 9A, 9aA at the same level in rows 11aA, 11cA corresponds to the vertical distance 12A. The mounting element 1A thus has a grid of holes, the distances of which are selected in such a way that, according to Figure 5 In addition, intermediate grids are generated by offsetting the grid 10A by half the spacing dimension in the horizontal and vertical directions, which enable additional elements to be more finely positioned and fixed on the mounting element 1A.

[0131] The same grid specifications are formed in the crossbeams 7aA, 7bA. In general, the grid 10A is selected so that when the crossbeams 7aA, 7bA are detachably fixed (in particular suspended) on two mounting elements 1A, the grid extends beyond the corresponding crossbeam 7aA, 7bA in the horizontal and vertical direction. The recesses 9A of the crossbeams 7aA, 7bA are designed in a keyhole shape. The crossbeams 7aA, 7bA each have a mirror symmetry along the vertical axis 17aA.

[0132] A rounded, substantially rectangular opening 16A is arranged in the center of the respective mounting area 5A. The cross-sectional area of ​​the opening is significantly larger than the cross-sectional area of ​​the recess 9A, in particular twice as large, and is used for passing hoses, cables, etc.

[0133] exist Figure 5In the embodiment shown in FIG. 1 , the two mounting elements 1A are designed as identical components. In another embodiment not shown here, the mounting elements 1A can also differ in their width, that is to say in their horizontal extension. For example, one mounting element 1A can have fewer rows 11A than the other mounting element 1A. In particular, one mounting element 1A can have only one row 11A, while the other mounting element can have at least four rows 11A, in particular six rows 11A. Any crossbars 7aA, 7bA between the two mounting elements 1A are then correspondingly longer.

[0134] exist Figure 6 The additional element 6A is also shown in the figure. The additional element 6A is hung by its rear wall into at least one recess 9A of the crossbeam 7aA or the mounting element 1A using a connecting element (not shown here), such as Figure 6 The additional element 6aA is designed to guide cables, which can be fixed on the corresponding additional element 6aA by means of clamping. The additional element 6bA is hung with its rear wall by means of connecting elements (not shown here) such as Figure 6 The additional element 6bA includes a clamp 20A for fastening a pipe 21A, such as a drainage pipe or the like.

Figure 5 and Figure 6 The mounting system 100A is different, depending on Figure 7 The mounting system 100A of FIG. 1 does not have an opening 16A in the corresponding mounting element 1A. Likewise, there is no laterally protruding protrusion 14A. Figure 7 In the mounting element 1A of the present invention, vertical projections 15A are now provided on the fixing region 4A. These components are arranged in a plane in front of the plane of the mounting region 5A and enable the mounting element 1A to be installed directly from the front in the recess 3A of the base cabinet 2A by means of a stop on the front side of the rear wall of the base cabinet 2A. In addition, the fixing region 4A and the mounting region 5A are additionally connected to each other at the end sides by a reinforcement 19A. In addition, the crossbeams 7aA, 7bA are designed to be higher or wider and thus have more rows of notches 9A and are Figure 7 In the embodiment, the cross beam 7 is not only mirror-symmetrical along the vertical axis 17aA, but also mirror-symmetrical with respect to the horizontal axis 17bA.

[0137] Figure 8 An additional element is shown fastened to an extension element of the mounting system.

[0138] Figure 8 An additional element 6A is shown, which has a clamping device 20A for accommodating a hose 22A. The clamping device 20A is made of plastic and comprises a round base 20aA and two essentially U-shaped clamps 20bA, between which the hose 22A is pressed and then fixed in a releasable friction fit in the clamps.
