Description

The present invention relates to a drawer according to the preamble of claim 1 and a method for assembling a drawer.

The DE 20 2014 104 925 U1 discloses a connecting device for two wall elements of a movable furniture part, which are arranged at an angle to one another, in which two attachment sections are provided and one of the attachment sections can be inserted into an opening of a wall element. As a result, the wall elements can be fixed to one another, the holding forces being rather low and rattling noises can occur if one of the wall elements is arranged with play due to tolerance. In addition, only one connection of two vertical wall elements is possible with this connection device. GB 1,587,722 discloses a drawer in which a connecting element is provided in the corner area, into which one end of a plate-shaped side wall and a plate-shaped rear wall can be inserted. Furthermore, a slot is provided into which a bottom of the drawer is inserted.

DE 20 2013 011426 U1 discloses a drawer in which an adapter ensures the connection between the floor and the side frame.

It is therefore the object of the present invention to create a drawer with an adapter for fixing a base to a side frame of a drawer for a piece of furniture, which allows simple assembly and reliable fixing of the base and the side frame.

In addition, a corresponding assembly method should be provided.

This object is achieved with a drawer with the features of claim 1 and a method with the features of claim 12.

According to the invention, the drawer has an adapter element with a first groove-shaped receiving channel for fixing a base, and a second groove-shaped receiving channel is also provided on the adapter element, into which a rear wall with an edge area can be inserted and can be clamped using at least one claw. As a result, both a base and a rear wall can be easily mounted on the adapter by pushing the base into the first receiving channel and the rear wall into the second receiving channel. Such a joint connection is also in Easily feasible as part of automated production. In addition, the at least one claw on each receiving channel can ensure a stable fixation of the floor and rear wall.

Preferably, the claws are each designed to be bendable and rest on the floor or the rear wall in a clamping manner. The claws can be elastically deflected about an axis parallel to the longitudinal direction of the respective receiving channel in order to rest against the floor or the rear wall in a clamping manner in the assembled position.

For a stable fixation of the bottom or rear wall, the claws can have one or more points at the end that can dig into the material. Since the floor or the rear wall are usually made of a wood material, for example an MDF or HDF board, the tips can dig into the corresponding material and prevent the floor or rear wall from being pulled out.

The first receiving channel is preferably delimited by an upper wall and a lower wall and the claws are provided on the lower wall of the receiving channel and thus press the base from below against an upper wall of the first receiving channel. As a result, the positioning of the base with respect to the upper surface is precisely specified, and thickness tolerances of the base can be compensated for by the elasticity of the claws.

Preferably, the claws are each aligned inclined to a wall of the receiving channel, each receiving channel comprising two walls and a bottom wall. The claws are preferably web-shaped on one of the walls, the angle of inclination between the claw and the wall in a range between 15 ° to 45 °, preferably 20 ° to 40 °, so that a pivoting of the claws when inserting the floor or Back wall can be done. The inclination of the claws is aligned such that the tips are directed towards a bottom wall of the respective receiving channel.

In a further embodiment, the first and the second receiving channel have essentially the same width. As a result, the same plate-shaped pieces of material with an identical width dimension can be used for the rear wall and floor, which simplifies production. Alternatively, for Bottom and rear wall panels of different widths or different materials can also be used.

The adapter is preferably made from a bent metal sheet, in particular from a single component. The two receiving channels are aligned at an angle, in particular at right angles, the receiving channel for the rear wall being arranged behind the end of the receiving channel for the floor so that the rear wall at least partially covers a rear end wall of the floor after assembly.

The claws are preferably formed integrally with the adapter, a one-piece, bent metal part preferably being used as the material. The claws can, however, also be designed as separate components from the adapter, whereby these can alternatively also consist of a different material than the adapter, for example a spring steel. For this purpose, the claws are attached to the adapter using fasteners.

In a drawer according to the invention, an adapter is preferably arranged in a side frame, on which a connecting section is formed, on which a web of the side frame is fixed, so that it is stably fixed to the adapter.

In the method according to the invention, a base is first positioned on a first groove-shaped receiving channel and a rear wall on a second groove-shaped receiving channel of the adapter, and then the base is pushed into the first receiving channel and the rear wall into the second receiving channel by a relative movement, preferably the insertion takes place from the floor and back wall at the same time. For assembly, both a movement of the adapter towards the floor and the rear wall and, conversely, a movement of the rear wall and the floor towards the adapter is possible, so that only the relative movement is important.

A drawer 1 comprises a plate-shaped bottom 2 and a plate-shaped rear wall 3, which are made, for example, from a wood material such as an MDF or HDF board. Side frames 5 are provided on both sides of the bottom 2. A front panel on the side opposite to the rear wall 3 was shown in Figure 1 omitted. In the front area, the side frame 5 has a hollow chamber 4 on which a fastening mechanism for a front panel can be arranged.

In Figure 2 a side frame 5 is removed from the bottom 2 and the rear wall 3. It can be seen that the base 2 is fixed on a rear adapter 6 and two further adapters 7. The side frame 5 comprises an outer wall 50, an upper edge 51 and an inner wall 52. The outer wall 50 projects beyond the inner wall 52 towards the rear, as shown in FIG Figure 3 is shown. The inner wall 52 is made shorter, and the rear wall 3 has a front side on an end side of the inner wall 52, while the upper edge 51 and the outer wall 50 encompass the front sides of the rear wall 3. In addition, the rear wall 3 is gripped from behind by a wall 20 of the adapter 7.

The fixation of bottom 2 and rear wall 3 on the adapter 6 is in the Figures 4 to 6 shown. The adapter 6 made of a bent metal sheet, in particular a steel sheet, comprises a first receiving channel 9 into which an edge of the base 2 is inserted. Furthermore, a second receiving channel 8 is provided at right angles thereto and offset to the rear, which surrounds an edge region of the rear wall 3. On the first receiving channel 9, claws 10 projecting obliquely upward are formed on the lower wall 14, which rest in a clamping manner on an underside of the base 2 and press the base 2 against an upper wall 13 of the receiving channel 9. Here, the upper wall 13 acts as an abutment against the elastic effect of the claws 10. In a similar way, the rear wall 3 is clamped by claws 11, the claws 11 being formed on a rear wall 20 of the receiving channel 8 and the rear wall 3 against a wall 18, which is arranged on the front side of the receiving channel 8 with respect to the drawer 1. The adapter 6 is arranged in the side frame 5, the outer wall 50 of the side frame 5 being connected to the adapter 6 with a bent web 53 on a connecting section 21 formed on the adapter 6, for example by gluing or welding. The connecting section 21 is not formed continuously on the longitudinal side of the adapter 6, but only in certain areas, preferably only as a connecting section 21 in a central area of the respective adapter 6, the width dimension being less than a third of the total width of the adapter 6. An inner wall 52 of the side frame 5 is angled towards the bottom 2 and is clamped between an upper side of the base 2 and the upper wall 13 of the receiving channel 9, so that the adapter 6 also serves to fix the side frame 5.

In the Figures 7A and 7B An exemplary embodiment is shown in which, instead of a plate-shaped rear wall 3 made of a wood material, a modified rear wall 3 ′ made of a bent steel sheet is mounted on the adapter 6. The other components of the drawer 1 are unchanged, in particular the adapter 6 is designed as in the previous embodiment. The rear wall 3 'engages with an end section in the receiving channel 8 of the adapter 6, but is fixed there with an additional clamping element 30 due to the significantly smaller thickness, as shown in FIG Figure 8 is shown. The clamping element 30 is rod-shaped and inserted into the receiving channel 8 so that the claws 11 fix the clamping element 30 and an edge of the rear wall 3 'in the receiving channel 8 in a clamping manner. In this case, the clamping element 30 can be connected to the rear wall 3 in a form-fitting manner and also be enclosed loosely. The clamping element 30 can thus be used to compensate for differences in thickness on the rear wall.

Figure 9 shows an alternative embodiment of a rear wall 3 ″, which is fixed to the adapter 6 without an additional clamping element 30. For this purpose, the rear wall 3 ″ is bent over in a U-shape at the front end 31 and comprises a leg 32, which has a trough-shaped profile 33, in which the claw 11 of the receiving channel 8 engages. As a result, the rear wall 3 ″ can be fixed in the receiving channel 8 in a clamping manner by means of the claw 11 through the U-shaped bent end.

For the assembly of a drawer, a side frame 5 is positioned on a holder 40, as shown in FIG Figure 10 is shown schematically. The angular holder 40 comprises several holding elements 41 distributed in the longitudinal direction of the side frame 5, which have one or more web-shaped swords 42 which can be inserted between the outer wall 50 of the side frame 5 and a bottom wall 12 of the receiving channel 9 on the adapter 6 and 7. The distance between the web-shaped swords 42 is selected so that it is the same or slightly larger than the width of the connecting section 21. The adapters 7 are designed like the adapter 6, except for the area of the rear receiving channel 8 which is missing in the adapters 7. The rear holding element 41, the one facing the rear wall 3, also has an additional bar-shaped sword 43, which has larger dimensions than the other swords 42 in terms of width and height. Its height is adapted to the height of the rear wall 3, so that during the assembly process, pressure can also be exerted on the area of the claws 11 protruding into the receiving channel 8.

As in Figures 11A, 11B and 12A, 12B is shown, a base 2 is positioned adjacent to the receiving channels 9 on the adapters 7 and 6, and a rear wall 3 adjacent to the receiving channels 8 on opposite adapters 6 for mounting the drawer. By a relative movement between the adapters 6 and 7 and the base 2 and the rear wall 3, an edge area of the base 2 and the rear wall 3 can be pushed into the receiving channels 8 and 9, with the holder 40 with the adapters 6 and 7 can be moved and the bottom 2 and the rear wall 3 can remain stationary. It is of course also possible to reverse the movement and move the floor 2 and the rear wall 3 or to move both relative to one another. The relative movement between the adapters 6 and 7 and the base 2 and the rear wall 3 preferably takes place simultaneously and preferably in an automated production process. However, assembly in successive assembly steps in automated or manual production is also possible. During this assembly movement, the web-shaped swords 42 on the holders 40 provide the necessary contact pressure in order to push the edges of the base 2 and the rear wall 3 into the receiving channels 8 and 9. For this purpose, each bar-shaped swords 42 each comprise a connecting section 21 formed on the adapter 6. By inserting the bar-shaped swords 42 and the larger-sized sword 43, a spatial separation between the outer wall 50 and the adapter 6 is effected, so that when the Bottom 2 in the receiving channel 9, no damage to the outer wall 50 serving as a visible surface can occur. In the process, the claws 10 and 11, which are each aligned at an angle to the bottom of the receiving channel, are bent elastically, and thus ensure a clamping fixation of the bottom 2 and rear wall 3.

It is of course also possible for the assembly to push the side frames 5 onto the bottom 2 and rear wall 3 by pressing on the respective outer wall 50. In such a case, the connecting section 21 can be dispensed with, so that the outer wall 50 comes to rest directly on the adapter 6.

In Figure 13 a drawer 1 is shown in which the bottom 2 and rear wall 3 are mounted on the side frames 5, the adapters 6 and 7 not being visible from the front in the mounted position. In addition, a pull-out guide 60 was mounted on each of the side frames 5, which has a mounting bracket 61 that can be fixed to a furniture body or body of a household appliance.

In Figure 14 a section through the drawer 1 is shown, from which the arrangement of the pull-out guide 60 and the bottom 2 can be seen. The pull-out guide 60 comprises an upper running rail 62 on which an underside of the base 2 is supported. The running rail 62 can be moved via rolling elements and a central rail on the stationary guide rail, which is formed integrally with the bracket 61. The adapter 6 fixes an edge of the base 2 through the receiving channel 9, the claws 10 pressing the base 2 from below in a clamping manner against an upper wall 13 of the receiving channel 9, with an angled web between the upper wall 13 and the top of the base 2 54 of the inner wall 52 of the side frame 5 is set. The side frame 5 is fixed on the outer wall 50 at a connecting section 21 of an angled web 53, so that the adapter 6 also serves to fix the side frame 5.

In Figure 15 A modified embodiment of a drawer is shown in the side area, in which the pull-out guide 60 is no longer arranged under the bottom 2, but inside the side frame 5. For this purpose, the side frame 5 has a hollow chamber that is slightly wider so that the upper edge 51 'is wider than in the previous embodiment. In addition, the outer wall 50 of the side frame 5 is no longer connected to the adapter 6, but to a connecting element 65 which rests on the running rail of the pull-out guide 60. As a result, the pull-out guide 60 is arranged to be particularly protected. In addition, the bottom 2 is fixed in the receiving channel 9 and the rear wall 3 in the receiving channel 8 of the adapter 6, as has been described above.

In Figure 16 the adapter 6 is shown in detail. The adapter 6 comprises a receiving channel 9 for the base 2, on which two web-shaped claws 10 protrude at an angle, which at the end have a plurality of tips 16 which extend into the material the soil 2 can dig. The claws 10 are aligned with a bottom wall 12 of the receiving channel 9, which is formed between the upper wall 13 and the lower wall 14. On the lower wall 14, a vertical web 15 is formed, on which the claws 10 are molded. On the bottom wall 12 of the receiving channel 9, an embossing is provided for forming a connecting section 21, on which the outer wall 50 of the side frame 5 can be fixed.

The adapter is produced as a one-piece, bent metal part, the lower receiving channel 9 being formed integrally with a wall 17, to which the receiving channel 8 adjoins at the rear for fixing the rear wall 3. The receiving channel 8 comprises a front wall 18 and a rear wall 20 which are connected to one another via a bottom wall 19 which is stepped and which forms a stop for an end face of the rear wall 3. On the rear wall 20, claws 11 are formed, which are also aligned in the shape of a web and inclined to the bottom wall 19. Several tips 16 are also formed on the claws 11.

The claws 10, 11 can also be designed as separate components from the adapter 6, whereby these can alternatively also consist of a different material than the adapter 6, for example a spring steel. For this purpose, the claws are fixed on the adapter 6 by connecting means.
