DETAILED DESCRIPTION OF THE INVENTION

(7) In FIG. 1 is shown a drawer wall element 1 having a drawer front connection unit 2. The drawer front connection unit 2 is fitted in a chamber portion 3 of the drawer wall element 1 to an end-face end 1a of the drawer wall element 1.

(8) The drawer wall element 1 comprises a wall profile part 4, which is divided by bending edges 5a and 5b into an inner wall sheet portion 6, an outer wall sheet portion 7, and a top edge sheet portion 8. The chamber region 3 is defined by a space enclosed by the three sheet portions 6, 7 and 8. In the chamber region 3 is arranged, moreover, a filling element 9, with which the inner wall sheet portion 6 and the outer wall sheet portion 7 are held at a distance apart of a width dimension B. As a result of the filling element 9, the inner wall sheet portion 6 and the outer wall sheet portion 7, at least in the region of the filling element 9, cannot be compressed, so that advantageously the drawer wall element is stabilized in its shape.

(9) On a rear end face 1b, the drawer wall element 1 has a rear wall connector 10, with which a rear wall can be fitted to the drawer wall element 1.

(10) On a bottom side of the drawer wall element 1, the outer wall sheet element 7 protrudes downward beyond a bottom edge of the inner wall sheet portion 6. In this case, on a bottom edge 6a of the inner wall sheet portion 6, a plurality of bottom-receiving profile parts 11 are fitted to the drawer wall element 1, which are intended to fit a drawer bottom (not shown) on the bottom edge 6a of the inner wall sheet part 6.

(11) In FIG. 2, the drawer front connection unit 2 is represented with further details. To a mounting plate 12 is fitted in an upper region, for example adjoining a top edge 12a of the mounting plate 12, a first front-fastening element 13. A second front-fastening element 14 is fastened in a lower region of the mounting plate 12.

(12) A height F of the mounting plate 12 is tailored to a height dimension H of the chamber portion 3 and tallies, in particular, with the height dimension H. The front-fastening elements 13 and 14 are arranged on the same side face 12b at a comparatively large distance apart on the mounting plate 12. As a result, a large part of the height dimension H of the chamber portion 3 can be utilized as the lever length in order to absorb, for example, lateral force effects transversely to the longitudinal axis of the drawer wall element. Such force effects can arise, for example, if a comparatively tall article, for example a drinks bottle, tips over and falls against, for example, the bending edge 5a.

(13) To the mounting plate 12 can be fitted a filling element 15, which extends over the width dimension B and bears in the chamber portion 3 against the inner wall sheet portion 6 and against the outer wall sheet portion 7.

(14) The front-fastening element 13 is fitted with holding clamps 16a, 16b and 16c to the mounting plate. The holding clamps 16a, 16b and 16c protrude on the side face 12b from the mounting plate 12 and are shaped into right-angled U-profiles. Preferably, the holding clamps 16a-16c are punched out of the mounting plate 12 in such a way that they are connected on one side to the mounting plate 12 and are bent out of the mounting plate. The surface of the front-fastening element 13 and the holding clamps 16a-16c can be mutually coordinated in such a way that the holding clamps 16a-16c on the front-fastening element 13, which, in a position shown in FIGS. 2 and 3a, is fitted to the mounting plate 12, are latched in place for a positive connection. For another drawer wall element (not shown), there can be provided, instead of the front-fastening element 13, no front-fastening element at all, as shown in FIG. 3b. In particular for a warehousing of the drawer front connection unit 2 as a component for furniture production or as a spare part, it is an advantage if the holding clamps 16a-16c are configured as detachable fitting means for the front-fastening element 13.

(15) The front-fastening element 14 is preferably connected in a fixed and non-detachable manner to the mounting plate 12. On that embodiment of the drawer front connection unit 2 which is shown in FIGS. 1-3b, the front-fastening element 14 is different from the front-fastening element 13. The front-fastening element 14 has a main body 18, which is non-detachably fastened to the mounting plate 12. To the main body 18 is fitted a shaft body 19, the position of which is displaceable and adjustable in the vertical direction with a set screw 20. The shaft element 19 is configured to receive a plug element 21 and comprises a latching device (not shown), with which the plug element 21 can be secured in a plugged-in position in the shaft element 19. The main body 18 and the shaft element 19 together form a socket for the plug element 21.

(16) In an opening 22 is arranged an unlocking element 23, which can be moved in order to release the latched-in plug element 21 in the opening 22, for example with a suitable screwdriver (not shown). Furthermore, the shaft element 19 has a set screw 24, with which a horizontal position of the plug element 21 in the shaft element 19 is adjustable. For an assembly, on the plug element 21 are configured two dowel pins 25, which are intended to be hammered into corresponding bores (not shown) on an inner side of a drawer front (not shown). The plug element 21 of the other front-fastening element 14 can thus be fitted to the drawer front (not shown) and afterwards plugged into the shaft element 19 for a latching connection. By means of the adjusting elements 20 and 24, following latching of the plug element 21, a positioning of the drawer wall element 1, and here of a drawer bottom (not shown) inserted on the bottom-receiving profile parts, on a drawer front (not shown) is advantageously possible. For the just described adjustment possibilities, the inner wall sheet part 6 can be breached and open at appropriate places in order that the adjusting elements 20 and 24, for the purpose of the adjustment, are accessible by a user.

(17) In FIG. 4, the front-fastening element 13 is represented in detail. A cuboid main body 26 has a cylindrical recess 27, in which a hollow-cylindrical bearing journal 28 is arranged such that it protrudes centrally. Into the cylindrical recess 27 is inserted a hollow cylinder body 29, which is mounted rotatably on the bearing journal 28. The cylinder body 29 is fitted to the main body 26 with a holding pin 30, which is rotatably engaged within the bearing journal 28. The holding pin 30 here engages positively in a central square opening 40 on the cylinder body 29. Into the holding pin 30 can be inserted, for example, a Phillips screwdriver (not shown), with which the holding pin 30 and, via this, the cylinder body 29, can be turned in and counter to the direction of the arrow D.

(18) On the main body 26 is configured a funnel-shaped shaft opening 36, which has an inwardly converging, rectangular cross section. Through the shaft opening 36, the cylindrical recess 27, and thus the cylinder body 29, are reachable from an end face 26a.

(19) The front-fastening element 13 comprises a plug element 32 having a, for example, cylindrical pin 34, which on a free end has a spherical thickening 35. If a mark 38 on the cylinder body 29 and a mark 39 on the main body 26 are arranged in close proximity to each other, the thickening 35 of the plug element 13 can be introduced through the shaft opening 36 into a slot opening 31 on a cylinder casing wall 37 of the cylinder body 29. Counter to the arrow direction D, the slot opening is of narrowing configuration, wherein the slot opening has in the axial direction of the cylinder body a width which corresponds to a diameter of the cylindrical pin. The cylinder casing wall 37 can here back-grip the plug element 13 at the thickening 35, whereby the plug element 13 can be jointly locked on the main body 26 by rotation of the cylinder body 29 in the arrow direction D.

(20) On that end of the pin 34 which lies opposite the thickening 35 is configured a dowel portion 33, with which the plug element 13, can be hammered into a corresponding bore (not shown) on a drawer front (not shown) for fastening purposes.
