DETAILED DESCRIPTION OF THE INVENTION

(6) FIG. 1 shows in perspective view a drawer wall element 1 according to the invention, which is configured as a hollow chamber casing and is made of a sheet metal material. A wall profile part 3 of the drawer wall element 1 has a hollow chamber section 2, which is bounded by an inner wall sheet section 4 and an opposite outer wall sheet section 5, which extend in the longitudinal direction of the drawer wall element 1 over its basic height. The inner wall sheet section 4 and the outer wall sheet section 5 are connected to each other at their upper end via a web-like horizontal connecting section 10, which is formed by two right-angled bent-over sections.

(7) For the representation of the inside of the chamber section 2, the inner wall sheet section 4 is represented only with its marginal regions. On the wall profile part 3, four identically configured base-receiving profile parts 6, 7, 8 and 9 are present, fixedly welded-on. The four base-receiving profile parts 6, 7, 8, 9 are likewise formed from sheet metal material having a plurality of bent-over sections or stamped-out regions. Each base-receiving profile part 6 to 9 respectively comprises a support surface region 11 for providing underside support to a drawer base (not represented), which latter is insertable on the drawer wall element 1 with a section of a longitudinal margin. Between the base-receiving profile parts 6 and 7, 7 and 8 and 8 and 9, a vacant intermediate region 12 without a base-receiving profile part is respectively obtained.

(8) For the connection of the drawer wall element 1 to a rear wall (not represented) of a drawer constructable with the drawer wall element 1, a drawer rear wall connection unit 14, which on the inside is fixed with a section 15 to the outer wall sheet section 5 and reaches partially into the chamber section 2, is fitted to a rear region of the drawer wall element 1. Moreover, the drawer rear wall connection unit 14 comprises a section 16, which is oriented at an angle to the section 15 and at the rear end of the inner wall sheet section 4 protrudes at an angle over the total height thereof.

(9) On a frontal end region of the drawer wall element 1, moreover, a drawer front connection unit 17 is present in a hollow space 13 of the chamber section 2.

(10) For the stabilization or stiffening of the drawer wall element 1 and for an attunement of sound or noise characteristics of the drawer wall element 1 in the ready-mounted usage state of the drawer assembled with the drawer wall element 1, a plurality of filler pieces consisting of respectively separate components are in the inserted state present on the drawer wall element 1 in the hollow space 13 and clamped therein. When an object or a person bangs against the drawer or against the drawer wall element 1, or due to some other mechanical interrelationship, the drawer or the drawer wall element 1 or its inner wall sheet section 4 and/or its outer wall sheet section 5 are set vibrating in consequence of the hollow chamber section 2, whereby noises in a comparatively high pitch are generated, which is undesirable.

(11) In order to avoid this, the filler pieces are provided in the chamber section 2. In the case of the drawer wall element 1, the filler pieces comprise a base filler element 18, a rear filler element 19, which is disposed on the drawer rear wall connection unit 14, and three further auxiliary filler elements 20, 21 and 22, which are detachably accommodated on, for example plugged onto, the drawer front connection unit 17.

(12) All filler elements or filler pieces 18 to 22 consist of a suitable, in particular, noise-damping synthetic material and have in the inserted state according to FIG. 1 spring elements with a defined pretension.

(13) In the inserted state, the base filler element 18 represented on an enlarged scale in FIG. 3 extends vertically on the inside between the connecting section 10 and a lower part or the base-receiving profile part 8 on the drawer wall element 1. The base filler element 18 has at its lower end, as the definedly pretensioned spring element, a spring bow 23, which comprises a spring bar 24 and an arcuately elongate recess 25, which partially frees the spring bar 24. In the clamped-in state, the spring bar 24 can spring back somewhat upward in the direction of the recess 25 or downward, in particular, according to the double arrow P1, for example, by fractions of a millimeter, for instance when there are load peaks on the drawer wall element 1. Advantageously, the spring bar 24 is on the underside seated on a web section 26 of the base-receiving profile part 8. In the represented assembly position of the drawer wall element 1, the web section 26 is, in particular, oriented horizontally or roughly parallel to the support surface region 11 of the base-receiving profile part 8.

(14) Advantageously, the arrangement on a drawer wall element can be such that that, exactly beneath a base filler element 18, a corresponding base-receiving profile part is centrally positioned. In FIGS. 1 and 2, the base filler element 18 is offset somewhat rearward relative to the middle of the base-receiving profile part 8, yet is supported against this on a part of the web section 26.

(15) On the base filler element 18 are configured, moreover, a total of six slightly arcuately running spring elements 27, which are free on their end face and can rebound slightly according to P2. The spring elements 27 are convexly curved in the direction of an inner side of the inner wall sheet section 4. The base filler element 18 has a circumferential frame part 28, having recesses or material gaps in an inner region, framed by the frame part 28, of the base filler element 18.

(16) On the base filler element 18, on a left half and a right half, three spring elements 27 are respectively configured one above another in an upper section 18a, a middle section 18b and in a lower section 18c of the base filler element 18 and connected on the frame part 28 via, in each case, a bending joint. The spring elements 27 lead to a defined pretension in the inserted state in the chamber section 2, wherein the spring elements 27 bear under pretension against the inner side of the inner wall sheet section 4, so that the spring elements 27 essentially provide a stiffening or stabilizing effect transversely to the longitudinal direction of the drawer wall element 1 by virtue of the base filler element 18 in the chamber section 2.

(17) A corresponding stiffening or stabilizing effect in the vertical direction is rendered, in particular, by the spring bar 24.

(18) High up on the inner side of the connecting section 10, the base filler element 18 is supported via a vertical frame bar 28a.

(19) On the drawer front connection unit 17 according to FIG. 4, which is represented in isolation on an enlarged scale, the auxiliary filler element 21 is omitted, in contrast to the view according to FIG. 2.

(20) The auxiliary filler elements 20 to 22 serve in particular to brace the chamber section 2 in the front end region, or the filler element 19 on the rear wall connection unit 15 in the rear end region, between inner sides of the inner wall sheet section 4 and of the outer wall sheet section 5 and can behave in this direction somewhat resiliently, in particular, in order to absorb load or tension peaks on the inner wall sheet sections 4 or outer wall sheet sections 5. To this end, spring elements 19a or 20a, 21a and 22a are present on the filler elements 19 or 20-22.

(21) With the stabilization and stiffening by virtue of the filler elements 18 to 22, a sound adaptation is also obtained moreover, to the effect that in the region of the chamber section 2 a resonance resulting from an external influence or a bump from outside against the drawer wall element 1 sounds comparatively deeper or vibration energy is absorbed and sounds less loud.

(22) In addition, filler or noise-damping material, such as, for instance, foaming or self-hardening material such as polyurethane, can be introduced into the hollow space 13 of the chamber section 2 in order to have a stabilizing effect and to damp noises on the drawer wall element 1.
