This object is achieved with a rear wall having the features of claim 1, a drawer according to claim 16 and a furniture according to claim 20.

Advantageous embodiments of the invention are defined in the dependent claims.

The fact that the rear wall has at least one additional stiffening device separate from the rear wall holders for increasing the stability of the sheet metal, which is preferably detachably connectable to the metal sheet, makes it possible to retrofit such a stiffening device to an existing drawer if required can increase the stability of the back wall.

Thus, the same sheets can be used for different drawers, which extend substantially over the entire width of the drawer. In a drawer in which a stiffening device is not necessary, only the sheet is used for the rear wall, in a drawer in which a more stable rear wall is needed, a same sheet is used and there is an additional - but preferably two - such stiffening device for use. As a result, costs can be kept low in production, since not two different sheets, which extend substantially over the entire width of the drawer, must be made. It has proven to be particularly advantageous if the at least one stiffening device lies at least partially between the drawer side walls of the drawer in the mounting position of the rear wall on the drawer.

It is particularly preferred to provide that the at least one stiffening device in the mounting position of the rear wall of the drawer is substantially completely located between the drawer side walls of the drawer.

Furthermore, it is preferably provided that the at least one stiffening device is in mounting position of the rear wall of the drawer next to the rear wall brackets of the drawer.

It is particularly preferred in turn provided that the at least one stiffening device in the mounting position of the rear wall of the drawer has a lateral distance to the rear wall brackets.

It has proven to be particularly advantageous if a fastening position of the at least one stiffening device along the width of the sheet can be selected freely.

It has proven to be particularly advantageous if the at least one stiffening device is formed in one piece.

According to a preferred embodiment it can be provided that the stiffening device is made of sheet metal. Furthermore, it can preferably be provided that a bottom of the embossment in the assembly position of the at least one stiffening device is spaced from the metal sheet. It has proved to be particularly advantageous if the at least one stiffening device in the mounting position has a lateral distance from the edge of the sheet. Particularly preferably, it may be provided that a stiffening device has a lateral distance to a left edge of the sheet and a further stiffening device has a lateral distance to a right edge of the sheet, As particularly advantageous, it has been found when the at least one stiffening device in Mounting position in an upper region has a U-shaped cross-section.

According to a preferred embodiment it can be provided that the flap in the mounting position - after bending - prevents removal of at least one stiffening device from the sheet.

a detail of Figure 18.

Figures 1 and 2 show two different perspective views of a piece of furniture 100. The furniture 100 in this case has a furniture body 101 and arranged therein a drawer 50.

The drawer 50 has a rail guide system 56, with which the drawer 50 can be moved relative to the furniture body 101. Furthermore, the drawer 50 has a front panel 53 and a rear wall 10. The rear wall 10 consists of a substantially over the entire width of the drawer 50 extending sheet metal 1 1 and an attached stiffening device 1 to increase the stability of the sheet 1 1 and thus the rear wall 10th

FIG. 3 shows a perspective view of a drawer 50. The drawer 50 has a drawer bottom 52, two drawer side walls 54 and 55, a front panel 53 and a rear wall 10. The two drawer side walls 54 and 55 are connected via the two rear wall brackets 21 and 22 to the rear wall 10.

The rear wall 10 in this case has a sheet which extends substantially over the entire width 51 of the drawer 50. On sheet metal 1 1 two stiffening devices 1 are attached in this preferred embodiment, in order to increase the stability of the rear wall 10.

It is thus shown in this figure 3, a rear wall 10 for a drawer 50, with a substantially over the entire width 51 of the drawer 50 extending sheet 1 1, wherein the rear wall 10 in the mounting position in the range of drawer side walls 54 and 55 of the drawer 50 is supported by rear wall brackets 21 and 22, the rear wall brackets 21 and 22 communicating with the drawer side walls 54 and 55, the rear wall 10 in this preferred embodiment 2 additional bracing devices 1 separate from the back brackets 21 and 22 for increasing the stability of the panel 1 1, which are connectable to the sheet 1 1.

Here is also clearly visible that the stiffening devices 1 are in mounting position of the rear wall 10 on the drawer 50 between the drawer side walls 54 and 55 of the drawer 50. It is also clearly visible here that the reinforcing devices 1 lie in the mounting position of the rear wall 10 on the drawer 50 next to the rear wall brackets 21 and 22 of the drawer 50.

Thus, the stiffening devices 1 in mounting position of the rear wall 10 on the drawer 50 a lateral distance to the rear wall brackets 21 and 22 (see also Figures 16, 17, 18 and 19). The stiffening devices were 1 - preferably by means of a screw - subsequently mounted on the plate 1 1.

As can be clearly seen in this illustration, the height 54 of the front panel 53 is at least twice - preferably at least three times - as large as the height 13 of the sheet 11. Especially in such a design of a drawer 50, the stiffening device 1 has a positive effect on the stability the rear wall 10, since the forces acting on the rear wall 10, in such drawers 50, in which the front panel 53 is much higher than the rear wall 10, larger.

In this preferred embodiment, the stiffening device 1 - more precisely, the two stiffening devices 1 - connected to the sheet 1 1 on a side facing away from the front panel 53 side 16 of the sheet 1 1, whereby the interior of the drawer 50 is not limited by the fastening device 1 and Furthermore, an aesthetic rear wall 10 can be achieved for a viewer.

In this preferred embodiment, the stiffening device 1 in mounting position on the sheet 1 1 a lateral distance to the edge of the sheet 1 1 on. Thus, in this embodiment, it can be clearly seen that the one stiffening device 1 has a lateral distance to the left edge of the sheet metal 1 1 in the mounting position and the other stiffening device 1 has a lateral distance to the right edge of the sheet metal sheet 1 1.

FIGS. 4 to 7 show a first variant of a stiffening device 1.

It can be clearly seen from these illustrations that the stiffening device 1 is preferably formed in one piece. This stiffening device 1 is also preferably made of a sheet. In the upper region, the stiffening device 1 has a U-shaped cross-section 19, which corresponds to a web 12 or a profiled portion of the sheet 1 1, not shown here (see Figures 1 1 to 15). The stiffening device 1 in this case has laterally folded-over webs 2 and 3, which extend substantially vertically in the mounting position of the stiffening device 1 and abut with their end faces 4 on the sheet 1 1 (see Figures 1 1 to 15). In the lower region of the stiffening device 1, an opening 5 is formed, with which the stiffening device 1 can be screwed to a drawer bottom, not shown here (see Figure 14).

In the upper region of the stiffening device 1, a flap 6 which is bendable in the direction of sheet metal 11 is formed which has an opening 8 for introducing a tool 51 (see FIG. 12) for bending the flap 6.

FIG. 4 shows how the flap 6 has not yet been bent; FIG. 6 shows how the flap 6 has already been bent.

FIGS. 8 and 9 show a second variant of a stiffening device 1 which has no flap 6. Instead, in order to increase the stability of the stiffening device 1, an embossment 7 is formed. With respect to this embodiment of the stiffening device 1, as shown in these figures 8 and 9, otherwise applies in the embodiment of Figures 4 to 7 mutatis mutandis.

In the figures 10 to 13, the individual steps of the assembly of the stiffening device 1 on the plate 1 1 of the rear wall 10 are shown in perspective.

In this case, the stiffening device 1 with its upper portion, which has a U-shaped cross section 19, placed over the folded-over web 12 of the sheet 1 1. Subsequently, the end faces 4 of the folded webs 2 and 3 (web 3 not visible here, see Figures 5 and 7) of the stiffening device 1 on the sheet 1 1 (Figure 1 1, 12, 13). The tab 6 of the stiffening device 1 is not yet bent in this state. Now you put a tool 51 in the opening 8 of the flap 6 and bends with this tool 51, the flap 6 in the direction of the plate 1 1 (Figure 12). After removal of the tool 51 (Figure 13), the stiffening device 1 can no longer be lifted off the plate 1 1, since the curved web 6 prevents this.

Now additionally, the stiffening device 1 is bolted in its lower region through the opening 5 with the plate 1 1 and a Schubiadenboden 52, not shown here (see Figure 14). Thus, the assembly process is completed.

FIGS. 14 and 15 show, in a side view, an already mounted stiffening device 1 on the sheet metal 11 - as also reflected in the situation in FIG.

From this view, it can be clearly seen that the bevelled webs 2 and 3 (web 3 not visible here, see Figures 5 and 7) abut with its end face 4 on the plate 1 1. Furthermore, it can be clearly seen from this illustration that the stiffening device 1 in its mounting position extends in its height 16 substantially above the height 13 of the metal sheet 11. In this preferred embodiment, it is even so that the stiffening device 1 protrudes beyond the sheet 1 1 both at its upper and at its lower end and thereby holds both the upper end of the sheet 1 1 and the lower end of the sheet 1 1 ,

At the lower end, the stiffening device 1 is fastened by means of a screw, not shown here, to the drawer bottom 52, whereby this takes place through an opening in the stiffening device 1 and through an opening in the sheet metal 11. Otherwise, that mentioned under the figure 13 applies.

FIG. 15 shows a detailed view of the upper region of the rear wall 10 as shown in FIG. In this figure 15 is clearly visible how the stiffening device 1 in mounting position, the profiled portion of the sheet 1 1 - which is formed in this embodiment as a folded bridge 12 - surrounds and thus allows a good grip of the fastening device 1 on the plate 1 1. By the bending of the flap 6 of the flap 6 moves under the folded web 12 of the sheet 1 1, whereby a lifting of the stiffening device 1 from the plate 1 1 is no longer possible.

From this illustration of FIG. 15, it can further be clearly seen that the upper region of the stiffening device 1 has a U-shaped cross section 19, which surrounds the folded web 12 of the metal sheet 1.

From the figures 10 to 15 is thus clear that the rear wall 10 by at least one separate stiffening device 1 for increasing the stability of the sheet 1 1 has, which - in this preferred embodiment, also releasably - with the sheet 1 1 is connectable.

FIGS. 16 to 19 now show in a perspective view how the second variant of the stiffening device 1 can be mounted on a metal sheet 1 extending substantially over the entire width 51 (see FIG. 3) of the drawer 50.

From these figures 16 and 17 can be clearly seen that a fixing position of the stiffening devices 1 along the width 51 of the plate 1 1 is arbitrary.

In this second variant of the stiffening device 1, this does not have a deflectable flap as the first variant (see Figures 10 to 13), but a facing in the direction of the sheet 1 1 stamping 7. This stamping 7 serves the increased stability of the stiffening device 1, what in a further consequence also leads to an increase in the stability of the sheet 1 1, at which the stiffening device 1 - in this preferred embodiment releasably - can be fastened. In this case, the bottom 9 of the embossment 7 in the mounting position of the stiffening device 1 is spaced from the sheet metal 1 1 and is thus not on the plate 1 1 at. However, the folded-over webs 2 and 3 of the stiffening device 1 are very well with their end face 4 on the sheet 11 in order to increase the stability of the sheet 1 1 and thus the stability of the rear wall 10.

Otherwise, with regard to the assembly of the stiffening device 1 of Figures 16 to 19 mutatis mutandis, everything mentioned under the description of Figures 10 to 14 (unless it is the flap 6).

It is once again clearly visible from FIGS. 16 and 18 that the drawer 50 has side walls 54 and 55 and likewise a drawer bottom 52 and a rail extension system 56. In FIG. 17, the opening 5 of the stiffening device 1 and the opening 15 of the sheet metal 1 are also good 1 recognizable, by which the stiffening device 1 is preferably fastened with a screw on the plate 1 1 and subsequently to the drawer bottom 52. It can be clearly seen from all the exemplary embodiments stated that the stiffening device 1 is a separate subassembly which serves to increase the stability of the metal sheet 11 and which, in these exemplary embodiments, can be detachably connected to the metal sheet 11. From FIG. 18, it can further be clearly seen that the stiffening device 1 has a lateral distance from the edge of the sheet metal 1 in the mounting position, wherein a stiffening device has a lateral distance to the left edge of the sheet metal 1 1 in the mounting position and the second stiffening device 1 has a lateral spacing to the right edge of the sheet 1 1 has.
