Description

DESCRIPTION

Furniture drawer and drawer wall element for a drawer Current state of the art

Extendable and / or drawers mounted slidably on the furniture body of a piece of furniture, are generally assembled from various basic elements already prepared, such as for example two side walls of the drawer, a back wall, a front wall and A drawer bottom. For high quality drawers, which are designed for a high maximum load and a long service life in a large number of repeated dynamic opening and closing processes, the stability of the drawer wall elements is highly demanded, especially with a reduced use of material and advantageous production. Thanks to document DE 10 2008 024 673 A1, a drawer wall element with the characteristics of the generic term of claim 1 is known.

Object and Advantages of the Invention

Object of the present invention is to provide a drawer side wall and / or a technical and economically favorable drawer cabinet, particularly with respect to the assembly of the basic elements and / or their stability and the necessary use of material for the basic elements.

15 This object is resolved by independent claims.

Favorable variants of the invention are set forth in the dependent claims.

The invention relates to a drawer wall element for a drawer, in which an edge section of a bottom of the drawer can be inserted, to form a side wall of the drawer adjacent to the bottom of the drawer, where the wall element of the Drawer comprises a profiled part of the wall and a profiled receiving part of the bottom, 20 which in each case are configured as separate and mutually adjusted pieces of a sheet material and which can be connected aligned with each other to the wall element of the drawer , so that an existing support surface can be provided in the wall element of the produced drawer in the profiled receiving part of the bottom for a lower support for a bottom of the drawer that can be inserted in the wall element of the drawer. In addition, it is essential that first the profiled part of the wall and the profiled receiving part of the bottom are produced in each case separately, which is particularly relevant with respect to a planning according to the intended design of the variable set of wall element of drawer from two, three or more profiled bottom receiving parts with a profiled wall portion.

The joining of the profiled receiving parts of the bottom with the profiled part of the wall is carried out once for permanent cohesion particularly by adhesion of materials and / or non-detachable parts. 30 For this purpose, for example, types of joining such as welding, adhesion, welding and / or clinching or riveting are also taken into account. The drawer wall element forms, after mounting the drawer, a part of the drawer, which apart from this generally comprises another drawer wall element, a rear wall and a front part.

The profiled part of the wall as well as the profiled receiving part of the bottom each consist of a profile type sheet metal material with a thickness in the range of millimeters, which is produced from a flat sheet by bending, punching or other processing steps particularly with several bending edges. The profiled part of the wall is designed, in the assembled state of the drawer, particularly to form a lateral limit of a reception volume of the drawer above the bottom of the drawer. The profiled bottom receiving parts particularly provide the connection of the bottom of the drawer to the wall element of the drawer.

A bottom of the drawer is particularly plate-shaped and is, for example, made of wood material.

The essence of the invention resides in the fact that the profiled part of the wall comprises a chamber section with a sheet section of the inner wall and a sheet section of the outer wall, which are oppositely separated along a width of the drawer wall element from each other and connected above by a bent area, where the sheet section of the outer wall melts below in an extension section, which extends further down than a lower edge of the sheet section of the inner wall, and that in the profiled receiving part of the bottom there is a support section angled upwards from the support surface, where in the connected state of the profiled part of the wall and the part The bottom receiving profile is supported by the support section with its rear face in the extension section, where the support surface for the bottom of the drawer extends along the distance between the s ection of internal wall plate and sheet section of the external wall. This distribution is favorable in view of a minimized material and productive cost 50 with simultaneous maximum mechanical stability of the drawer wall element in the state of the assembled drawer.

In relation to the previous and / or subsequent spatial designations, reference is made to an orientation in the state of use of the drawer wall element and / or an orientation of the drawer formed therewith. Accordingly, a longitudinal direction of the drawer wall element in the longitudinal direction of the drawer and / or in the direction of extension and insertion of the drawer relatively to the cabinet body originates. Seen transversely to the longitudinal direction of the drawer wall element and horizontally and / or parallel to an upper face of the bottom of the drawer, the width of the drawer wall element originates.

More favorably, in the drawer wall element according to the invention, a reception volume for the longitudinal edge section of the bottom of the drawer is offset from the known distributions in the direction of the width of the drawer wall element. The receiving volume for the edge section of the bottom of the drawer extends in the width direction at least along a considerable part of the width of the drawer wall element, particularly along the entire width of the wall element of the drawer.

Furthermore, the front side of the bottom of the drawer extended laterally along the drawer wall element arrives, in the inserted state, up to the area of the sheet section of the external wall. There, the support section and the extension section have a stabilizing effect, that is, there where the forces and moments, for example, in the case of a very loaded drawer, by means of the effective weight of the material loaded in the drawer, through the Bottom of the drawer are inserted and / or absorbed into the wall element of the drawer.

It is also advantageous that above the profiled receiving part of the bottom, separated from the support surface, there is a traverse section, which connects to the support section by means of a flexion of material, where the traverse section bridges a distance between the sheet section of the outer wall and the sheet section of the inner wall. It is also beneficial that, separated along the thickness of the bottom of the drawer and / or in a vertical direction with respect to the support surface, the bottom of the drawer comes into contact with an upper face with a section, formed by the traverse section, opposite the support surface of the profiled receiving part of the bottom. The bottom of the drawer used is fixed, particularly held, according to this between the support surface and the opposite traverse section. The traverse section is aligned particularly parallel to the support surface. It is also favorable for a clamping action on the inserted edge section of the bottom of the drawer that the size and / or extension of the traverse section corresponds at least almost to the size and / or extension of the support surface, especially because the surface support and traverse section oppose each other.

It is also advantageous that an extended support traverse has been adjusted at a free lower edge of the sheet section of the inner wall in the direction of the sheet section of the outer wall in such a way that the profiled receiving part of the bottom is supported in the support traverse. With the support traverse, which fits properly to the profiled receiving part of the bottom, the drawer wall element is stabilized with the effect that the traverse section rests on the support traverse. Therefore, the profiled receiving part of the bottom in the profiled part of the wall is in support contact with both the sheet section of the outer wall and / or the extension section and also with the sheet section of the inner wall and / or with the support traverse. Together, this counteracts the load peaks in the drawer in the assembled state and / or load state.

The distribution of the charges of the profiled receiving part of the bottom over the profiled part of the wall along the support traverse and of the extension section is favorably carried out continuously along the total length in question of the profiled receiving part of the fund, because the corresponding sections that support each other, that is the extension section and the support section and / or the traverse section and the traverse section, are configured without interruption along of the total length in question in the respective components.

The support traverse is particularly formed by a strip of material folded for example at right angles and / or to the horizontal and / or by a material at the bottom edge of the sheet section of the inner wall. In the direction of the width of the drawer wall element, the support traverse is configured with a particularly equal width of for example about 30% of the total width according to the distance there between the sheet section of the inner wall and the sheet section of the outer wall.

A favorable modification of the object of the invention is characterized in that an upward angled support edge is configured in the traverse section, which comes into contact with an internal face of the internal wall sheet section oriented to the sheet section of the external wall This particularly increases the stability and torsional stiffness of the drawer wall element in the connection area of the profiled receiving part of the bottom with the internal wall sheet section. Especially favorable is also that the adjacent flat support edge extends somewhat upwardly on the surface of the inner surface of the sheet section of the inner wall. The forces can thus be absorbed and distributed in a particularly favorable manner, which acts by bracing and counteracting load peaks when using the drawer. The height of the support edge angled upwards can be designed more or less depending on the desired stability.

It is also advantageous that, in the extension section, in comparison with other areas of the profiled part of the wall, there is a reinforced area in material through a section of folded sheet. Since the extension section receives a considerable proportion of the weight transmitted from the bottom of the drawer to the profiled receiving part of the bottom, the material reinforced area acts favorably on the stability and stiffness of the drawer wall element and therefore of a formed drawer with the.

Apart from this, with a material existing integrally in the sheet used and / or without an additional or separate piece, the reinforcement can be configured by zones in the extension section. This is also favorably carried out with a forming process, which is used anyway in the production of the profiled parts, that is to say a bending process. According to this, no additional tools or auxiliary tools are necessary either.

In addition, it is favorable that in the area of the extension section internally, mutually displaced surface areas are configured in a stepped manner, which adjust to complementary surfaces mutually displaced in a staggered manner on the rear face of the support section such that the section of support is supported by the extension section, where the displaced surface areas and the complementary surfaces displaced mutually adjacent are in support contact. This is stable and particularly favorable in view of a precise alignment of the elements involved. Apart from this, a flat and / or full adjustment is achieved through a zone in mutual contact between the support section and the extension section. This measure also improves the stability and torsional stiffness of the drawer wall element.

It is also favorable that the mutually displaced surface areas in a stepped manner comprise in the extension section an area of folded material of the extension section. The displaced surface areas thereby contribute to the function of a mechanical reinforcement by means of the area of folded material in front of the other profiled wall parts with a simpler material thickness. The area of the material reinforcement can be at least two-layer or also multi-layer, particularly through a bending of the sheet material. This is carried out, for example, through a section of bent sheet material along a considerable height of the extension section. In particular, a flat sheet material can be used for the elaboration of the profiled wall part together with the reinforced material zone, without a separate operational step and / or other tool being necessary for the area of bent and / or reinforced material.

It is also favorable that the mutually displaced surface areas in a stepped manner comprise in the extension section an area of folded material, separated from an internal face of the extension section by an air gap and / or touching an internal face of The extension section. In this way, the desired height differences of the displaced surface areas can be favorably realized, particularly only by operational bending steps.

More favorably, the traverse section and the support surface are present such that a distance between the support surface and the traverse section is adjusted to a thickness of the bottom of the drawer. Particularly the distance is adjusted to the thickness of the edge section that can be used from the bottom of the drawer. With this, the edge section can be inserted comfortably adjusted to the support surface and the traverse section and incorporated in a fixed manner.

In addition, it is proposed that, according to a favorable arrangement of the object of the invention, there is an area of material folded downwards on an edge of the support surface opposite the support section, which extends to the area of a lower edge of The extension section. The area of material folded down can serve as a stop surface for an underground guide mounted on the bottom face of the bottom of the drawer. With this, an exact alignment of the bottom of the drawer used together with the underground guide can be simplified.

It is further favorable that a reception volume for the bottom edge section of the drawer is provided in the profiled receiving part of the bottom such that the bottom edge section of the drawer can be in contact with angularly oriented sections of the part background reception profile. With the alignment particularly at right angles of the sections that delimit the reception volume, it is possible for a bottom of the drawer in the form of a chair in its basic form, to have upper, frontal and lower surfaces aligned at right angles in the edge section , an optimal fit from a bottom edge section of the drawer to the finished drawer wall element.

More favorably there is exactly one profiled part of the wall and at least two profiled parts receiving the bottom. This is, for most of the drawer wall elements used in practice, a sufficiently stable distribution considering a minimized material cost. With two profiled bottom receiving portions, lower storage of the bottom of the drawer is provided through two separate zones, which is mechanically favorable.

If, for example, for a comparatively longer drawer wall element, more than two profiled bottom receiving parts were necessary, these could be provided without correspondingly minor difficulty in the

drawer wall element and / or on the profiled part of the wall. The various profiled bottom receiving portions are further oriented with their support surfaces aligned with each other, so that each flat support of the corresponding lower areas of the bottom edge sections of the drawer is carried out on the respective support surfaces in the inserted state of the bottom of the drawer.

In particular, different lengths of the profiled wall parts can be used, so that three or more of the profiled bottom receiving parts can also be arranged on a profiled part of the wall. In this way, for longer profiled wall portions, a profiled part of the reception of the anterior bottom and a rear part can be provided with other profiled parts of the reception of the bottom.

Finally, it is also favorable, that on a profiled part of the wall, seen in the longitudinal direction of the profiled part of the wall, a profiled receiving part of the bottom is connected in a front end area of the profiled part of the wall and another profiled bottom receiving part in a rear end zone of the profiled part of the wall. In the middle there may be an area without a profiled receiving part of the bottom and / or therewith no support surface for a central part of the edge section of the bottom of the drawer. Both profiled bottom receiving parts of a drawer wall element are particularly identical, which is economically favorable and / or enables the production of the drawer wall element from only two different components.

The invention relates, apart from this, to a furniture drawer with a drawer wall element, where the drawer wall element is designed according to one of the aforementioned configurations. In particular, the profiled part of the wall limits a useful volume area of the drawer. In the furniture drawer there are on both sides 20 and / or each one wall element of the drawer for the lateral reception of the respective longitudinal edge section of the bottom of the drawer. The furniture drawer generally also has a rear wall and a front face.

Other features and advantages of the invention are described further on the basis of an exemplary embodiment according to the invention. Individually shows:

Figure 1 a profiled receiving part of the bottom of a drawer wall element according to the invention according to Figure 3 in a simple front view,

Figure 2 a profiled part of the wall of the drawer wall element according to Figure 3 also in a simple front view,

Figure 3 the drawer wall element according to the invention in front view with the profiled receiving part 30 of the bottom according to Figure 1 and the profiled part of the wall according to Figure 2 and

Figure 4 the drawer wall element according to Figure 3 in perspective view, in which a connection part of the rear wall is also arranged.

Figure 1 shows a profiled receiving part of the bottom 1 and Figure 2, a profiled part of the wall 3, which are configured mutually adjusted and can be connected in a non-detachable manner, to form a wall element of the drawer 4 according to The invention according to Figures 3 and 4. The wall element of the drawer 4 has two profiled receiving parts of the bottom 1 and 2 in the profiled part of the wall 3. Apart from this, in the wall element of the drawer 4, it has a connection part of the rear wall 5, with which a rear wall not shown for a drawer and the drawer wall element 4 can be connected. The profiled receiving parts of the bottom 1 and 2 and the profiled part of the wall 3 are produced as profiled elements in each case from a piece of a flat and / or smooth sheet material tailored for example by bending and stamping processes.

The profiled receiving parts of the bottom 1 and 2 are identical, where for their description below reference is made to the profiled receiving part of the bottom 1. The profiled receiving part of the bottom 1 comprises a support surface 6 for a lower support of an edge section R of a bottom of the drawer that can be inserted into the wall element of the drawer 4 (see Figure 3). To the profiled receiving part of the bottom 1 is connected a support section 7 angled upwards at a right angle to the support surface 6, which has a small asymmetry. The support section 7 is then followed forward, through another flexion 9 at right angles, a traverse section 8, separated oppositely above the support surface 6.

50 On the leading edge of the traverse section 8 there is a support edge 10 angled upward about 90 angular degrees. Between the support surface 6, the support section 7 and the traverse section 8 there is provided a reception volume 11 approximately in the form of a channel along the profiled part of

receiving the bottom 1 for a section of the edge section R that can be used from the bottom of the drawer, so that mutually angled sections of the longitudinal edge of the bottom of the drawer can be contacted with the corresponding angularly aligned sections of the surface of support 6, of the support section 7 and / or of the traverse section 8. A fragment of the edge section R of a bottom of the drawer inserted in the wall element of the drawer 4 is suggested discontinuously in Figure 3. From the support surface 6 and the traverse section 8, tongue-shaped and slightly projecting contact surfaces 6a and 8a are formed by incisions for contact with the edge section R of the bottom of the drawer.

Apart from this, in the profiled receiving part of the bottom 1, by an edge of the support surface 6 opposite to the support section 7, there is an area of material 12 folded down.

The profiled part of the wall 3 comprises along a considerable height H1 a chamber section 13, which has a sheet section of the inner wall 14 and a sheet section of the outer wall 15. The sheet section of the flat outer wall 15 and the sheet section of the flat inner wall 14 are aligned parallel and opposed by a width B1 uniformly. The sheet section of the inner wall 14 and the sheet section of the outer wall 15 are joined above by a zone 18 in the form of a band limited by bends 16 and 17 corresponding to the width B1.

The sheet section of the outer wall 15 has an extension section 19 below, which in the direction of the height has the height H2, so that the total height of the profiled part of the wall 3 is composed of the heights H1 and H2. In the mounted drawer, the wall element 4 of the drawer is in the interior above the height H1 above the bottom of the drawer.

At the lower edge of the sheet section of the inner wall 14 there is internally a traverse support 20 protruding in the direction of the sheet section of the outer wall 15, formed by a marginal strip folded down in the sheet section of the sheet inner wall 14. Above the support traverse 20 a front section of the traverse section 8 of the profiled receiving part of the bottom 1 is supported.

In the connected state of the profiled receiving part of the bottom 1 and the profiled part of the wall 3 according to Figures 3 and 4, the support edge 10 is in contact with an inner face 21 of the sheet metal section of the wall internal 14.

The extension section 19 is partially mechanically stabilized with a zone reinforced in material 22. The zone 22 extends along at least a large part of the height H2 seen from the bottom edge of the extension section 19, so that there is only a comparatively thin zone 23 of simple material thickness in the extension section 19. The material reinforced zone 22 in the extension section 19 is made through a sheet of sheet bent up 180 degrees angular in the section of external wall plate 15.

The extension section 19 internally presents surface areas 24 and 25 mutually displaced in the direction of a wall thickness of the extension section 19. The surface area 25 is aligned with an internal face 27 of the sheet metal section of the wall external 15. The surface area 24 is raised towards the internal face 27, partially separated from the internal face 27 by an air gap L, and formed by the area of folded material 22. The surface areas 24 and 25 are smooth and parallel. The area of folded material 22 rests through small areas above and below on the inner face 27.

The support section 7 correspondingly to the surface areas 24 and 25 has complementary mutually displaced sections 28 and 29, which, in the connected state of the profiled receiving part of the bottom 1, come into contact with the profiled part in a supportive manner. of the wall 3 in the surface areas 24 and 25, which acts in a stabilizing and / or reinforcing manner on the wall element of the drawer 4.

Figure 4 clarifies both profiled receiving portions of the bottom 1 and 2 in the wall element of the finished drawer 4, where the profiled receiving portion of the bottom 1 ends with its front front face with a front front face of the profiled part of the wall 3. The profiled receiving part of the bottom 2 ends with its rear front face with the rear front face of the profiled part of the wall 3. Between both profiled receiving parts of the bottom 1 and 2 there is a free longitudinal area 26 in the inside the drawer wall element 4.

Both profiled receiving portions of the bottom 1 and 2 are preferably welded to the profiled portion of the wall 3.
