Description

"Drawer wall element"

The invention relates to a drawer wall element according to the preamble of claim 1 and a piece of furniture.

In the field of furniture drawer wall elements in various designs are known. In this case, a drawer wall element made of metal is often used especially for furniture, from which an increased load capacity is expected. In this case, the wall element can e.g. be made of a metal sheet by punching and bending in a relatively robust form. Compared to the processing of other materials, a metallic drawer wall element with a relatively high

Precision be made.

The invention is based on the object

To provide drawer wall element for a rational and stable production of drawers.

The task is accomplished by a drawer wall element with the

Characteristics of claim 1 solved.

Preferred and advantageous embodiments of the invention are specified in the subclaims. The starting point of the invention lies in a

Drawer wall element for a drawer, on which a

Edge portion of a drawer bottom is used to form an adjacent to the drawer bottom drawer side wall. In this case, the drawer wall element comprises a wall profile part and a bottom receiving profile part, wherein the

Drawer wall element a on Bodenaufnahmeprofilteil

existing support surface is provided for an underside support for an insertable on the drawer wall element drawer bottom, and wherein the wall profile part a

Chamber portion comprising an inner wall sheet metal portion and an outer wall sheet metal portion, the opposite across a width dimension of the drawer wall element from each other

spaced and connected by a bend.

The essence of the invention is that a for

Support surface upwards angled contact section

is present, and that at the bottom receiving profile part above objected to the support surface, a web portion is provided, which adjoins the contact portion by a Materialumbiegung, wherein in the support surface and / or in the

Web section at least one free resilient, over the surface of the bearing surface or facing the bearing surface side of the web portion raised flap is provided.

The edge portion of the drawer bottom is located on opposite sides in the handle of the support surface and the web portion between which can pinch the edge portion of the drawer bottom. Preferably, the

Support surface and the web section for this in a for

Support surface vertical direction arranged largely overlapping each other. The bottom receiving profile part may extend over an entire length of the drawer wall element in its longitudinal direction or over part of the total length. If a bottom receiving profile part extends over only a part of the length of the drawer wall element, the

Drawer wall element several, e.g. two or three,

Have Bodenaufnahmeprofilteile.

Due to the free resilient tab, which depends on the support surface or the web portion is raised, can ensure a pressing force when a thickness of the drawer bottom, for example

due to variations in production varies.

Under a raised arrangement of the freely resilient tab is meant that an upper side of the tab on the

Support surface protrudes beyond the support surface and that in the case of a design of the tab on the web section the

Bottom of the tab protrudes downward from a web contact surface of the web section. By a distance between a raised surface of the tab and a provided by the support surface or the web portion

Surrounding area, the bottom receiving profile part may e.g. deviations of a thickness of a drawer bottom and e.g. be adapted to a desired clamping force for holding the drawer bottom advantageous.

This offers the advantage that the bottom receiving profile part can hold an edge portion of the drawer bottom on opposite sides thereof. This can be the

Floor receiving profile part with the help of the raised and free-resilient flap advantageously adapt to a varying thickness of drawer bottoms, the. production reasons

may occur.

The abutment section can be used as a stop during insertion, e.g.

be provided by pressing the Bodenaufnahmeprofilteils at the edge portion of the drawer bottom. This allows the tab to be located at a safe distance from a side edge of the

Drawer bottom be positioned to jump out of the drawer bottom, for. immediately after insertion of the drawer bottom in the bottom receiving profile part to avoid.

Preferably, the web portion bridges a distance, e.g. the width dimension, between the outer wall sheet metal portion and the inner wall sheet metal portion. In this case, the chamber section can be formed by the web section, e.g. at a bottom of the

Chamber section be at least partially closed. In the storage space can advantageously be provided a larger floor area available. A preferred embodiment is that the

Abutment section abuts the outer wall sheet metal section. As a result, in the region of the abutment, the outer wall panel section and the contact section can be additionally supported and stiffened. Optionally, the bottom receiving profile part and the wall profile part in the region of the contact portion, e.g. by a welding and / or e.g. a riveted joint fastened together, e.g. to increase the stability of the drawer wall element. At the contact section, an offset,

In particular, a step-shaped offset can be formed, with which the contact section can be supported on a step profile section on the outer wall sheet metal part.

The contact portion is preferably flat, whereby a

Narrow side of the drawer bottom can lie flush with the contact section.

For a rational production, the tab is preferably punched free of the material of the bottom receiving profile part. In addition, a tab, e.g. by riveting and e.g.

be attached by welding to the bottom receiving profile part.

At the tab may be formed a bend through which the tab is pressed against an adjacent drawer bottom. This allows an elasticity of the tab to a

Adjust the variation of the thickness of the drawer bottom. It is particularly preferred if the tab between a

Connection with the bottom receiving profile part and a

freestanding end has an S-shaped bend. This makes it possible to ensure that the tab can rest flat against the bottom of the drawer.

In addition, it is preferred that the tab on a

freestanding end an eyelet for performing a

Has fastening element. This can advantageously a drawer bottom to displacements parallel to a

Support surface to be prevented. The eyelets on the tab may be formed as a slot to tolerances of the position of a Anschraublochs on

To be able to balance the drawer bottom.

Moreover, it is preferred that the tab with a perpendicular to the support surface portion of the

Bottom receiving profile part, in particular with the

Annex section connected, connected. This advantageously prevents the bottom support section from being pushed away from the underside of the drawer bottom.

At the bottom receiving profile part, a counter-holding element

be formed, which is excellently arranged on a surface opposite to the tab and in the direction of the tab.

The bottom receiving profile part may be concealed by the outer wall sheet metal portion of the wall profile part at least from the support surface and above it.

Furthermore, it is preferred that the web section on

Inner wall sheet metal section is supported.

In the following, the invention will be explained with reference to an exemplary embodiment and explained with the help of drawings, which are not to scale. The reference numerals are used consistently in all figures for the same features. Show it:

Drawer wall element.

In Fig. 1, an embodiment of a drawer wall element 1 according to the invention is shown. The drawer wall element 1 comprises a wall profile part 3 and two Bodenaufnahme- profile parts 2, wherein one of the bottom receiving profile parts 2 at a front end face la and one of Bodenaufnahme- profile parts 2 at a rear end face lb of

Drawer wall element 1 is arranged. Furthermore, a rear wall connector 4 may be attached to the rear end face 1b of the drawer wall element 1.

The wall profile part 3 comprises an inner wall sheet metal section 6, a top sheet metal section 8 and an outer wall sheet metal section 7. The inner wall sheet metal section 6 and the

Outside wall sheet metal section 7 are connected to each other via the top sheet metal section 8. The upper side sheet metal section 8 is connected to the outer wall sheet metal section 7 by a bending edge 8a and to the inner wall sheet metal section 6 by a bending edge 8b, whereby a connecting bend is provided. The sheet metal sections 6, 7 and 8 are preferably made of a single contiguous

Sheet metal part produced and connected to each other throughout.

A single bottom receiving profile part 2 is shown in Figures 2 and 3 with further details. The

Bottom receiving profile part 2 has a support portion 9, which is preferably provided to a substantially horizontal arrangement, with a support surface 10, the

Supporting a bottom 18 a of a Schubbladenbodens 18 - as shown in Figure 4 - is provided. From the support section 9, a lower profile section 14 is bent by a bending edge 14a in an eg right angle. A bending edge 9a connects the support section 9 with a contact section 11. The abutment portion 11 is formed by an offset portion 11c in a lower abutment portion IIa and in upper

Section IIb subdivided. The lower one protrudes

Annex section IIa in a first plane E upwards. The upper portion IIb is arranged projecting parallel to a second plane F upwards. The offset portion 11c is bent in an S-shape and connected between the lower and upper abutment portions IIa and IIb. The contact section 11 is thereby adapted to a cross-sectional profile of the outer wall sheet metal part 7.

The upper abutment portion IIb is limited by a bending edge Lld, which is preferably parallel to the bending edge 9a

runs. By means of the bending edge 11d, a web section 12 can be formed in an e.g. project right angle from the upper abutment portion IIb such that the web portion 12 above the

Support section 9 and in particular parallel to

Pad portion 9 is arranged. At one of the bending edge lld opposite side of the web portion 12, a further bending edge 12a may be formed at the one

Profile section 13 is bent in particular projecting at right angles upwards. Including the bending edges lld and 12a, the web portion 12 may extend in a width G, which has a width dimension B of a chamber portion 5 in the

Drawer wall element 1 matches. The width dimension B may e.g. through the wall profile part 3, in particular through the

Be top side sheet metal section 8 with the bending edges 8a and 8b be predetermined.

The support surface 10 is interrupted by a plurality of openings 15a - 15d, at which the sheet material of the support portion 9 is broken. In each case, a largely planar, strip-shaped tab 16 is punched at each of the openings 15b and 15d, which is connected via an S-shaped bend with the rest of the floor receiving profile part. In the embodiment shown here, both tabs are formed in the same way, wherein a plurality of tabs may be formed differently in other embodiments not shown. The S-shaped bend 17 is the embodiment as

Connection of the tab 16 with the bending edge 14a parallel to this evenly shaped. At least one of the web portion 12 facing top of the tab 16 is over the

Surface 10 raised. The tab 16 is only indirectly with the support surface 10 via the bending edge 14a

connected. With an attached drawer bottom 18, as shown in Figure 4, caused during clamping deformations of the support portion 9 and the S-shaped bend 17 cooperate such that the tab 16

advantageous just on a bottom 18 a of the drawer bottom 18 rests. In particular, an inclination of the tab 16 to the support section 9 and, where appropriate, inclinations of the tab 16 and the support section 9 with respect to

Web section 12 be coordinated with each other so that the tab 16 at. different drawer bottoms 18 with

different floor thicknesses within a given tolerance always flat, in particular parallel to the bottom 18a of the drawer bottom 18 rests. Therefore, a plane C of the top of the tab 16 and a plane A of the support surface 10 may be inclined to each other. By way of example, the plane A can be ascendingly arranged from the bending edge 9a without clamping the bottom of the drawer and the plane C starting from the bend 17 can likewise rise comparatively easily. This advantageously ensures that an edge portion 18c of a drawer bottom 18 is always in frictional contact with the drawer wall element at least in the region of the tabs 16 with increased pressure.

At the tab 16 is an eyelet 19 e.g. stamped out for attachment of the drawer bottom 18 on the bottom receiving profile part 2 with e.g. a screw is provided. After insertion of the drawer bottom 18 between the

Web section 12 and the support section 9 can be secured by an example screwing the drawer bottom 18 against slipping or slipping on the bottom receiving profile part 2. At the web portion 12, a projection 20 is formed, which from an underside of the web portion 12 in the direction of

Support surface 10 protrudes. The projection 20 is located closer to the bending edge 11d than at the bending edge 12a. In Figure 5 it can be seen that the projection 20 via a

comparatively small portion of a longitudinal axis of the

Bottom receiving profile part 2 extends.

FIG. 4 shows an arrangement of the wall profile part 3 and the floor receiving profile part 2 on the drawer wall element 1 with the drawer bottom 18 inserted. The inner wall sheet metal part 6 is bounded at the bottom by a U-shaped bending edge 6a on which the inner wall sheet metal part 6 is bent inwardly. By a further bend is a flat portion 6b horizontally in the direction of the outer wall sheet metal part 7 inwards. In this case, the section 6b is about a bending radius of the U-shaped bending edge 6a with respect to a lower edge of the

Inner wall sheet metal section 6 is increased at the bending edge 6a.

The outer wall sheet metal part 7 projects beyond the inner wall sheet metal part 6 with an outer section 7a downwards. A folding edge 7b, on which a folding section 7c of the outer wall sheet metal part 7 projects inwards and partly on the section 7a, forms

S-shaped bends 7d and 7e, the folding portion 7c is partially spaced from the portion 7a in a plane parallel to the latter.

The bottom receiving profile part 2 is mounted so to speak with the profile section 13 and the web section 12 in the wall profile part, wherein the web portion 12 and the profile part 13 on a chamber portion 5 facing surface of the

Inner wall sheet metal section 6 abut. Of the

Web section 12 rests on the horizontal section 6b. As a result, with the projection 20 on the web section 12, the lower edge of the inner wall sheet metal part 6 on the U-shaped bend 6a can be pressed against an upper side 18b of the drawer bottom 18. Due to the projection 20, the U-shaped bend 6a and the tab 16, the drawer bottom 18 is fixed or held in position. With the web portion 12 are the Profile section 13 and the upper abutment portion IIb held at a distance through which the adjacent sheet metal parts 6 and 7 are arranged at least from the top 18b of the drawer bottom 18 to the top sheet metal section 8 in a parallel position to each other.

Below the offset portion 11c is the lower

Annex section IIa at the folding section 7c on. In this case, the bottom receiving profile part, for example, by a welding or a riveted example (not shown) may be fixed to the folding section, the fixation on the outer portion 7a would not be recognizable. The lower abutment portion IIa also forms a stop at the onset of the edge portion 18c of the drawer bottom 18, whereby the edge portion 18c protrudes over a large part of the width dimension B in the drawer wall element 1 and thereby stabilize the drawer wall element 1.
