This application is a national stage of International Application PCT/EP2010/058895, filed Jun. 23, 2010, and claims benefit of and priority to German Patent Application No. 20 2009 004 982.5, filed Jul. 2, 2009, the content of which Applications are incorporated by reference herein.
BACKGROUND AND SUMMARYThe present disclosure relates to a drawer which can be extended from and retracted into a furniture body. The drawer includes a bottom part, a front panel, two lateral frames and a back wall which is positively or non-positively connected to the end regions formed by the lateral frames via corner joints.
Such a drawer is known. In current industrially produced drawers, the lateral frames consist of hollow profile sections in which adapters are introduced for absorbing and transferring the forces to the pull-out guides. Corner joints are arranged at the end of the adapters which face the back wall. The back wall also often has to transfer forces to the lateral frames in addition to the mere delimiting function for the items disposed in the drawer. It can be arranged as a shaped sheet-metal part or as a panel which consists of wood or substitute wood material. The corner joints are usually arranged as shaped plastic parts in order to utilize the dimensionally and materially resilient properties of plastic materials for connection. The corner joints are usually arranged in such a way that the connection between the lateral frames and the back wall can occur without the help of tools.
In the case of a prior known corner joint, mounting journals spaced from one another are applied to the side associated with the back wall, on which the back wall is then inserted. For this purpose, the back wall is provided with boreholes arranged in a correctly positioned manner, which need to be adjusted precisely to the width of the drawer. The back wall is secured by means of hooks which are arranged in groups and which have a different length, so that respective hooks will engage behind the back wall on the outside depending on the actual thickness of the back wall. As a result of the only partly engaging hooks, the transfer of forces via the back wall is reduced and the precisely produced boreholes in the back wall increase the production costs per back wall.
These corner joints are complex from a constructional viewpoint as a result of the relatively high number of hooks, despite the fact that the joint consists of a single component.
Optionally, the drawers in question are provided with back walls which are arranged as shaped sheet-metal parts or as plate-like parts. The thicknesses of the shaped sheet-metal parts deviate from the thicknesses of the plate-like back walls; usually, the plate-like back walls are thinner than the shaped sheet-metal parts. As a result, different corner joints are also necessary.
The present disclosure further relates to providing a drawer of the kind described but having corner joints configured to be used both for plate-like back walls as well as for back walls that include shaped sheet-metal parts, with the transmission of forces being improved and the handling being as simple as possible.
Thus, an embodiment according to the present disclosure includes a corner joint that includes a first connecting part and a second connecting part that is connected in a pivotable manner to the first connecting part. The second connecting part includes at least one detent means which is configured to be connected to the first connecting part and/or to the back wall, wherein the first connecting part is connected to an adapter associated with an end region of the lateral frame.
The corner joint includes two connecting parts which are connected with each other in the manner of a hinge, such as via a living or film hinge by way of articulation. The first connecting part is configured to be connected fixedly to the adapter associated with the end region of the lateral frame. The second connecting part is configured to be moved in relation to the first connecting part in this phase. Subsequently, the second connecting part is pivoted to a position which stands at a right angle to the lateral frame. Thereafter, the detent means of the second connecting part are in engagement with the first connecting part. It is within the scope of the present disclosure that the detent means could also additionally or solely be connected to the back wall. This may apply when the back wall is arranged as a shaped sheet-metal part. It is within the scope of the present disclosure that each detent means may be disposed outside of the back wall and that the detent means of the two corner joints form stops, so that the end regions of the back wall engaging into the first connecting part are secured against displacement.
In an embodiment according to the present disclosure, each detent means of the second connecting part includes at least one undercut latching web, the contact surface of which engages behind an associated area of the first connecting part of the corner joint or the back wall arranged as a shaped sheet-metal part.
Each detent means is arranged in such a way that it is resilient when the second connecting part is pivoted to the end position. The detent means then jumps into the latched position in the end position of the connecting part.
According to an embodiment of the present disclosure, each detent means may include several undercut latching webs which are arranged in pairs. Since they are also arranged at a distance from each other, the second connecting part is fixed several times so that the latched connection is exceptionally secure.
Each latching web may, advantageously, be arranged or configured as a harpoon sleeve. Since the free end regions are arranged in the manner of a wedge, the adjoining region extends for forming the contact area. The harpoon sleeves that are arranged in pairs either engage behind the openings of the first connecting part or the openings of the back wall which delimit the edge, wherein the harpoon sleeves penetrate the openings of the first connecting part in the latter case just described.
In an embodiment according to the present disclosure, the area of the second connecting part facing the back wall is arranged in a plate-like manner and is offset in the manner of steps, with the free area disposed away from the pivot axis having the larger thickness. It is thereby within the scope of the present disclosure that the corner joint can be used both for back walls arranged as shaped sheet-metal parts and also for massive back walls. The thicknesses of the massive back walls may, advantageously, be lower than the back walls formed as shaped sheet-metal parts. In the case of massive back walls, the free end region with the larger thickness of the second connecting part rests on the back wall, whereas the region facing the pivot axis rests on the back wall in the case of back walls arranged as shaped sheet-metal parts, so that the free end region engages in the back wall by the amount of offset.
In an embodiment of the present disclosure, it is provided for fixing the height of the back wall arranged as a shaped sheet-metal part on the second connecting part that the first connecting part includes at least one recess in the corner region facing away from the pivot axis. Into the at least one recess a projection is arranged on the second connecting element that will engage in an interlocking fashion. The projection simultaneously engages into a notch on the edge side of the back wall. This will also help prevent movement resulting from forces that act on the latching webs, which forces act perpendicularly on the latching webs.
In an embodiment according to the present disclosure, the first connecting part is connected to the second connecting part via a film hinge. As a result, the corner joint can be regarded as an integral shaped part which can be made of plastic by way of a suitable die by injection molding. It is advantageous that both connecting parts are non-detachably connected to one another.
Embodiments of the drawer in accordance with the present disclosure are further disclosed in the claims and the following descriptions.
Other aspects of the present disclosure will become apparent from the following descriptions when considered in conjunction with the accompanying drawings.
The drawer 1, shown in
As is shown in
In an embodiment of the present disclosure, the first connecting part 8 includes a recess 13, in the corner region, facing away from the film hinge 18. A projection 14, attached to the inner surface of the second connecting part 9, engages the recess 13 in an interlocking manner in the latched position of the corner joint 7. The beveled boundary web of the back wall 6, arranged as a shaped sheet-metal part, is recessed with the same shape as the projection 14 in a correctly positioned way.
As shown in
It is advantageous and within the scope of the present disclosure that corner joints 7 of the same configuration can be used for both types of back walls 6.
It is within the scope of the present disclosure that the corner joints 7 may be arranged in two parts and be connected with one another in an articulated manner, with the second connecting part 9 which stands at a right angle to the lateral frame 4 being provided with a detent means, which may include several harpoon sleeves 12.
