Description

The present invention relates to a fastening arrangement with a drawer bottom and with at least one rail, on which a support for supporting a lateral edge of the drawer bottom and a wall section arranged at an angle to the support for connection to a side frame is formed, with at least one rail having at least one pivotally mounted claw is provided, which can be hammered into the bottom of the drawer, a U-shaped channel being formed between the support and the wall section, and a method for mounting a drawer on at least one rail.

The DE 10 2016 103 169 discloses an adapter for fixing a floor to a side frame, a lateral channel being formed on the adapter, on the lower wall of which a plurality of claws protruding obliquely upwards are formed, the tips of which can dig into the material of the floor. This prevents the floor from moving relative to the adapter, with the claws resting against the floor due to prestressing. It is not intended to drive the claws into the floor material with a tool.

The DE 93 039 03 U1 discloses a drawer in which claws are provided for fixing a floor, which are driven into an underside of the floor. The claws are not provided on a rail with a U-shaped channel, which increases the stability of the connection between the drawer bottom and a side frame, which is particularly advantageous for wider drawers.

Show further drawers with a fastening arrangement for a bottom of the drawer DE 197 17 184 and EP 626 144 .

It is therefore the object of the present invention to create a fastening arrangement with a drawer bottom which is of stable design and enables the drawer bottom to be effectively fastened to at least one rail.

This object is achieved with a fastening arrangement having the features of claim 1 and a method for installing a drawer bottom having the features of claim 11 .

In the fastening arrangement according to the invention, at least one rail is provided, which has a support for an edge of the drawer bottom and a wall section for connecting a side frame, which is preferably vertically aligned in the installed position, with a U-shaped channel being formed between the wall section and the support which increases the stability of the rail and stiffens the rail against twisting. Furthermore, at least one pivotally mounted claw is provided, which can be hammered into the bottom of the drawer, at least one recess being provided on a bottom of the U-shaped channel, and a tool for driving the claw in can be passed through the recess. This allows the drawer bottom to be effectively assembled to the rail by placing the rail against the shelf and then using a tool to hammer the claw into the drawer bottom by passing the tool through the recess at the bottom of the U-shaped channel. Optionally, several tools can be guided through a large number of recesses along the length of the rail in order to hammer several claws into the bottom of the drawer at the same time.

In a preferred embodiment, the at least one claw can be pivoted about an axis perpendicular to the longitudinal direction of the rail. In the mounted position, the axis preferably extends horizontally, so that the direction of movement of the at least one claw is essentially vertical when it is driven in. The at least one claw can advantageously be provided with an undercut in order to better secure the claw against being released from the drawer bottom again.

The rail essentially extends over the entire length of the drawer bottom for stable fixing of the drawer bottom. It is also possible to attach a plurality of individual rail sections to the drawer bottom, but one rail is preferably fixed to opposite sides of the drawer bottom.

In a first embodiment, the at least one claw is formed integrally with the rail. The at least one claw can be formed on a leg of the U-shaped channel and protrude into the channel. The The claw can thus be made from the material of the leg of the U-shaped channel and is then bent inward by the leg into an interior space of the channel in order to be able to be hammered into the bottom of the drawer there by a tool. Optionally, two claws can be produced on the leg of the channel, which are fixed on opposite sides of a recess and are accessible via a recess. The two claws can then be driven in at this recess, which pivot in opposite directions of rotation, since they are connected to the leg of the U-shaped channel on opposite sides. This increases the holding forces, since the claws dig into the material of the bottom of the drawer in opposite directions. The claws or the tool can advantageously be designed in such a way that both claws can be driven into the bottom of the drawer by the tool at the same time.

In an alternative embodiment, the claw is formed on a separately manufactured lever which is rotatably mounted on the rail. The lever can be designed as a two-armed lever and have at least one claw on a first lever arm and at least one actuating section for moving the claw on a second lever arm, with the recess on the bottom of the U-shaped channel providing access to the actuating section. A force can then be exerted on the actuating section by the tool in order to drive the claw into the material of the drawer bottom on the other lever arm. In this case, the claw is preferably driven into an upper side of the drawer bottom.

In a further embodiment, a locking mechanism is provided, by means of which the at least one claw can be locked in a locked position. This prevents the claw from swinging back after being driven in, which prevents the connection from loosening. The locking mechanism can take place, for example, by the claw latching onto a stop which prevents it from pivoting back.

In the method according to the invention, a drawer bottom is placed against the support of the rail, and at least one claw is driven into the drawer bottom by a tool through the at least one recess on the bottom of the U-shaped channel. Optionally, two claws can be hammered in simultaneously via the tool, for example if these claws are arranged next to one another, with the claws being preferred rotate in opposite directions. Furthermore, the claws can preferably be locked in a turned-in position.

A piece of furniture 1 comprises a furniture body 2 on which several drawers 3 are held so that they can be moved via pull-out guides. Each drawer 3 comprises a drawer bottom 4 which is arranged between two side frames 5 . A front panel 7 is fixed to the side frames 5 and a rear panel 6 is provided on the opposite side.

In figure 2 the drawer bottom 4 with the rear wall 6 and a side frame 5 is shown. The drawer bottom 4 is fixed to the side frame 5 , with an edge of the plate-shaped drawer bottom 4 , which is preferably made of a wood-based material, engaging in a receptacle below the side frame 5 .

In the Figures 3A and 3B the side frame 5 is shown without the drawer bottom 4. It can be seen that underneath the drawer bottom 4 there is a rail 10 which extends almost over the entire length of the side frame 5 and on which a support 11 is provided which supports an underside of the drawer bottom 4 . A receptacle 12 for an edge of the drawer base 4 is formed below the side frame 5 . A U-shaped channel 15 is provided on the underside of the receptacle 12 , on which several claws 13 are provided distributed over the length, which can be driven into the underside of the drawer bottom 4 .

In the Figures 4A to 4C the side frame 5 is shown with the rail 10 in different positions. It can be seen that the rail 10 has a support 11 that is horizontal in the installation situation and a vertical wall section 16, between which a U-shaped channel 15 with a horizontal base and two vertical legs is arranged. At least one claw 13 is arranged in an interior of the U-shaped channel 15 . The edge-side receptacle 12 for the drawer bottom 4 is covered at the top by a part of the side frame 5 .

The design of the rail 10 for fixing the drawer bottom 4 is in the Figures 5A to 5I shown in detail. The rail 10 consists of a bent and stamped metal sheet, in particular a steel sheet, which has a plurality of claws 13 distributed over the length, which are formed integrally with the rail 10 . Each claw 13 is on a flexible arm 14 held, which is connected to a vertical leg of the U-shaped channel 15. The claw 13 has an upwardly projecting tip that can be driven into an underside of the drawer bottom 4 . In the area of the claws 13 a recess 18 is provided on the bottom of the U-shaped channel 15 . Two claws 13 are provided in each case, which are formed on opposite sides of the vertical leg of the U-shaped channel and can be pivoted in opposite directions. When driving in with a tool, two claws 13 can be driven in at the same time, which are connected to the leg of the rail 10 on opposite sides and are thus pivotably mounted in opposite directions.

The claws 13 are also protruding into an interior of the U-shaped channel 15, as is particularly the case in FIGS Figures 5B and 5G is shown. The bendable arm 14 can be oriented at an angle of between 5° and 30° relative to the vertical leg of the U-shaped channel 15 .

In figure 6 a rail 10 with a drawer bottom 4 is shown. The drawer bottom 4 is placed on the rail 10 and the claws 13 are not yet engaged with the drawer bottom 4 .

In figure 7 the rail 10 is shown correspondingly figure 5 is formed, with a cover 20 being mountable on the rail 10 and enclosing the rail 10 . The cover 20 has a lower edge 21 , a side wall and an upper edge 22 for this purpose. For assembly, the cover 20 can be arranged on the wall section 16, as shown in figure 8 is shown. A drawer bottom 4 can then be inserted between the upper edge 22 and the support 11 . The cover 20 has recesses 23 in the area of the claws 13, so that the claws 13 can be driven into the drawer bottom 4 even when the cover 20 is present.

In figure 9 a further exemplary embodiment of a rail 10' is shown on which, instead of integrally formed claws, levers 30 are provided which are rotatably mounted on the wall section 16 of the rail 10'. A pivot axis 31 is provided on each lever 30 and extends perpendicularly to the longitudinal direction of the rail 10 ′ and is arranged in the wall section 16 . The lever 30 is designed as a two-armed lever and includes a first lever arm 32 on which a bent claw 33 is formed at the end. An actuating section 35 is formed on a second lever arm 34, as is shown in figure 10 is recognizable. The operating section 35 is accessible via a recess 36 in the bottom of the U-shaped channel 15 .

To mount a drawer bottom 4 is according Figure 11A First, a drawer bottom 4 is placed with its underside on the support 11, with an edge of the drawer bottom 4 covering the U-shaped channel 15. Optionally, an end face of the drawer base 4 can rest against the wall section 16, with a certain amount of play optionally also being able to exist. In the next step, a tool 40 that has a ram 41 is used. The plunger 41 is passed through the recess 36 on the bottom of the U-shaped channel 15 and meets the actuating section 35 on the second lever arm 34. By pressing or hitting the actuating section 35, the lever 30 is pivoted, the second lever arm 32 with the claw 33 is pressed against an upper side of the drawer bottom 4 in order to dig the claw 33 into the material of the drawer bottom 4 .

In the Figures 12A and 12B the drawer bottom 4 is shown in the assembled position. The drawer bottom 4 is fixed to the rail 10' by digging a plurality of claws 33 into the material at the top of the drawer bottom 4 so that movement of the drawer bottom 4 relative to the rail 10' is prevented.

When pivoting the lever 30, it can also be locked in such a way that during the pivoting movement a tab or a locking lug is passed over, which then locks behind the lever 30 on one of the lever arms 32 or 34, so that a backward pivoting movement of the lever 30 is prevented. This measure prevents the connection between the claw 33 and the drawer bottom 4 from being released by a backward pivoting movement. The tab or latch can be formed integrally with the rail 10 '.

In figure 9 webs 111 are shown on the rail 10' in the area of the support 11. These webs 111 rest on the underside of the drawer bottom 4 at the points where the claws 33 dig into the drawer bottom 4 from above. As a result, the drawer bottom 4 is stabilized.

The above exemplary embodiments can be combined with one another as desired. For example, a rail can be provided which has claws 13 which are driven into the underside of the drawer bottom 4 using a tool 40 . In addition, at least one can be connected to the same rail Lever 30 are provided, which drives a claw 33 into an upper side of the drawer bottom 4, so that the drawer bottom 4 is held securely between the claws 13 and 33. The number of claws 13 and 33 can be selected depending on the extension of the drawer bottom 4 in the longitudinal direction of the rail 10 or 10'.
