State of the art

For furniture with pull-outs or drawers, which are slidably mounted on a furniture body of the furniture on guides with telescopic rails, the extracts are usually assembled from prepared basic elements such as two drawer side walls, a rear wall, a front wall and a drawer bottom. For sturdy and high-quality drawers, hollow metal drawer side walls are frequently used.

The AT 401 853 B relates to a drawer metal, are secured to the brackets on which a panel is pushed.

Purpose and advantages of the invention

Object of the present invention is to provide improved drawers or drawer wall elements of the type described in the introduction, in particular as regards the stability and performance of the drawer in practice.

This object is solved by the independent claim 1.
The dependent claims thematize advantageous developments of the invention.
The invention is initially based on a drawer wall element for a drawer, to which an edge portion of a drawer bottom can be used to form a drawer side wall adjacent to the drawer bottom, the drawer wall element comprising a wall profile part and a bottom receiving profile part, wherein the drawer wall element is an am Floor receiving profile part existing support surface is provided for a bottom support for a drawer wall element insertable drawer bottom, and wherein the wall profile part comprises a chamber portion having an inner wall sheet metal portion and an outer wall sheet metal portion, the opposite spaced over a width dimension of the drawer wall element from each other and above a connection section are connected. The wall profile part and the bottom receiving profile part each consist of a profile-like metal sheet material with a thickness in the millimeter range, which is made of a flat sheet metal section by bending, punching and / or other processing steps, in particular with multiple bending edges. Accordingly, both profile parts are each made in one piece in particular and then in particular insoluble connected to the drawer wall element. The connecting portion between the inner wall sheet metal portion and the outer wall sheet metal portion is formed, for example, by a sheet portion bounded by two bends. The bottom receiving profile parts provide in particular the connection of the drawer bottom to the drawer wall element.
A drawer bottom is in particular plate-shaped, for example of a wooden material.

The essence of the invention lies in the fact that at least one filling element is inserted into the chamber section, which comprises at least one spring element pretensioned in the inserted state. The at least one filling element is designed, in particular, as a separate component which can be introduced into the chamber section in the correct position and fixed in a self-locking manner. The spring element is in particular configured in such a way that it is clamped between inner sections of the chamber section or presses resiliently against at least one inner section of the chamber section, for example against an inner side of the inner wall sheet metal section and / or the outer wall sheet section. In this way, loads acting on the drawer wall element can at least partially be absorbed by the filling element via the inner wall sheet metal section and / or the outer wall sheet metal section. This is mechanically and sonically advantageous. A drawer wall element can be individually equipped with one or more filling elements. The exact positioning of the filling elements in the chamber section can be chosen differently. In addition, the type of filling elements that can be accommodated in a chamber section can vary in size, shape and construction by selecting from a range of different filling elements.
The accommodated filling elements cause in particular by the defined bias advantageously a stabilization and a desired sound situation of the drawer wall element in the use state or in the finished drawer. This allows the drawer to be loaded or loaded to a maximum load. In addition, unwanted noise in the useful state of the drawer wall element are prevented or the sound of the drawer wall element improved in particular a comparatively dull sound is advantageously achieved. A comparatively high sound of a drawer wall element due to too large or free hollow areas is regularly perceived by users as unpleasant.

In particular, the at least one filling element clamps against the inner wall and outer wall or in the horizontal direction and / or in the vertical direction z. B. between the connecting portion and a bottom receiving profile part. In this case, the spring element abut against both mutually braced areas or the spring element itself is biased on only one of the two sections, wherein at the other portion another portion of the filling member is present, for example, a frame portion of the filling element.

Advantageously, the at least one filling element is designed such that it can be inserted into a wall profile part. Thus, the assembly or insertion of the filling element in the chamber section esp. Frontally on the wall profile part from the front or back or an open side of the chamber portion, for example, by hand.

Further, it is advantageous that the filling element is designed such that it is resiliently supported in the inserted state on the bottom receiving profile part. In general, the chamber portion over the length of the drawer wall element is open at the bottom. Only in regions or where a bottom receiving profile part is provided over individual longitudinal sections of the drawer wall element, an upper-side part of the bottom receiving profile part forms a lower boundary of the chamber portion, so that there the bottom support of the filling element is advantageously possible.

An advantageous modification of the subject invention is characterized in that at least one filling element is provided on a drawer rear wall connection unit. The drawer rear wall connection unit forms advantageous conditions for attaching the filling element to it in particular differently positionable. In addition, mechanically comparatively heavy loads can occur in the area of the drawer rear wall connection unit, with the filling element effectively having a stabilizing effect with the corresponding positioning of the filling element.

It is also advantageous that at least one filling element is provided on a drawer front connection unit. Thus, an advantageous attachment possibility for the filling element is provided in the front end region of the drawer wall element. The drawer front attachment unit provides multiple and / or different attachment locations for attachment of one or more fillers. According to the invention, the wall profile part and the bottom receiving profile part are each designed as separate and coordinated components from a sheet metal material and aligned with each other connected to the drawer wall element. Thus, advantageously, the variety of parts can be reduced to exactly one variant for the bottom receiving profile part. The wall profile part is determined only by its respective desired length, but identical in shape. For a particular selected length of the wall profile part can be individually tailored, the number of floor receiving profile parts are taken into account. Accordingly, the length of a bottom receiving profile part regularly is significantly shorter than the length of a wall profile part.
The wall profile part and the bottom receiving profile part are designed in particular for a compact arrangement with a partially nested arrangement or for a self-stabilizing connection by z. B. abutting portions of the bottom receiving profile part of opposite portions of the wall-profile part in their connection state, wherein the profile parts are preferably miteinender insoluble, for example, connected by welding together.
In particular, in a comparatively shorter drawer wall element or wall profile part exactly two bottom receiving profile parts can be attached and in a longer or higher loadable drawer wall element more than two bottom receiving profile parts can be attached to the wall profile part attached.

The bearing surfaces of the plurality of floor-receiving profile parts of a wall profile part are aligned with each other or are part of a common particular horizontal plane based on the state of use of the drawer.

It is also advantageous that a web portion is provided at the bottom receiving profile part above the support surface at a distance, which adjoins an abutment surface angled upward to the contact surface by a material bending. In each case of right-angled bend, a laterally open channel-shaped receiving volume for a longitudinal edge section of a drawer bottom insert that can be used on the drawer wall element is provided with the support surface and the opposite, in particular parallel web section and the contact section extending therebetween angled toward the support surface and the web section. The contact section is advantageously supported with its rear side facing away from the receiving volume at an extension section on the outer wall panel section. Thus, the drawer wall element is constructed highly stable.

In addition, it is advantageous for the web section to bridge a distance between the outer wall sheet metal section and the inner wall sheet metal section, with the result that the bearing surface and the web section also form over the width of the drawer wall element.

In this case, in addition to the bearing surface also above the support surface formed by a web portion additional contact surface extends for an upper side of the edge portion of the usable drawer bottom, which increases the overall stability of the assembled drawer.

According to a further advantageous embodiment of the invention, the filling element is supported on the web section. Thus, a support surface opposite to the connection portion for the underside support of the filling member is obtained in the chamber portion.

Furthermore, it is advantageous that the filling element has a spring bow at the lower edge. A spring bow is easy to produce and allows in addition to the provision of the defined bias of the spring element, a bottom support of the filler at a mating portion on the drawer wall element. Preferably, the spring bow is formed by a bent in the edge direction of the filling element extending slot over a substantial edge length at the bottom of the filling element. The spring or prestressing properties of the filling element can be determined, for example, by the height or width of the oblong hole and / or the material thickness of the material adjacent to the oblong hole of the spring bow at the lower edge of the filling element. A lower material thickness of the adjoining the slot material of the spring bow springs easier than a larger material thickness. If comparatively more material is taken out of the filling element, for example, by a larger or longer slot, the spring characteristic of the spring bow or of the preloaded spring element provided therewith can be influenced depending on this. A filler member for a drawer panel member according to any one of the above embodiments is adapted to a chamber portion of the wall profile member having an inner wall sheet portion and an outer wall sheet portion in the form, and comprises at least one spring member which is stretched in a state inserted into the chamber portion , The drawer wall element is designed in particular as a hollow chamber frame made of a sheet metal material. In the inserted state, the spring element is in particular adjacent to an inner side of the chamber section, wherein a loading of the spring element takes place in such a way that the spring element is biased. The drawer wall element may act on the drawer loads over the inner wall sheet metal portion and / or the outer wall sheet metal portion at least partially over the Pick up filling element. This can be with the filling element in the inserted state, the top of the drawer wall element achieve discussed benefits.

The invention also relates to a piece of furniture with a drawer wall element formed according to one of the above-mentioned embodiments. On the furniture, for example, with a furniture body and several slidably mounted thereon drawers with Hohlkammerzargen, the corresponding advantages discussed above can be achieved.
