EP4021246B1 - Device for fixing a drawer - Google Patents

Description

The present invention relates to a device for fixing a drawer to a rail of a pull-out slide, comprising a drawer, a fastening means fixed to a rail and a receiving element held on the drawer, which is at least partially overlapped by the fastening means, the receiving element being movable on the drawer is held and is biased towards the fastening means.

In the DE 20 2008 011 114 U1 A pull-out guide for drawers is shown, in which a hook is integrally formed or fixed on a rail of the pull-out slide. A spring element can be provided on the hook in order to clamp the drawer between the rear hook and a front fastening device. However, this reduces the overlap between the hook and the drawer.

A drawer has manufacturing-related tolerances in the longitudinal direction of a rail of the drawer guide. So that the pull-out guide can be used for different drawers, the length of the usually hook-shaped fastening means is limited in the longitudinal direction of the drawer, for example so that the fastening means can be inserted into an opening in a rear wall made of a wood material. If such tolerances result in a lack of overlap between the fastening means and a receiving element on the back of the drawer, the drawer is no longer secured against being lifted.

The DE 10 2018 114 712 A1 discloses a device for fixing a push element on a rail of a pull-out guide, in which a holding part is immersed in a fastening device and is fixed there via clamping bodies. The clamping bodies are arranged on both sides of the holding part and are supported on an inclined side wall for clamping.

In the DE 10 2013 114 722 A1 a receiving unit is disclosed in which an insert tip is held between two receiving bodies. By adjusting the receiving unit, the inclination of the drawer is adjusted. The receiving bodies are spring-loaded and therefore biased towards the insertion tip.

ES 1 016 155 discloses a further fastening device for fixing a thrust element.

The EP 1 986 523 B1 therefore proposes an adjustable bracket at a rear end of a running rail in order to fix a drawer. The adjustable holder has a large number of components, so that assembly and manufacture are complex.

It is therefore the object of the present invention to create a device for fixing a drawer to a rail of a pull-out slide, which uses simple means to compensate for tolerances in the event of length changes due to production.

This task is achieved with a device with the features of claim 1.

In the device according to the invention, the receiving element, which is at least partially covered by the fastening means, is movably held on the drawer and biased towards the fastening means. As a result, tolerance compensation can take place in the longitudinal direction of the rail, so that sufficient coverage of the fastening means on the receiving element is ensured. This ensures that the drawer is securely fastened to the rail of the pull-out runner.

According to the invention, the receiving element is arranged in an assembly position at a distance from a rear wall and a bottom of the drawer and is moved during assembly via the fastening means to the drawer against the force of a spring or the elastic receiving element. As a result, in the mounted position, the fastening means can rest against the receiving element in a clamping manner, the clamping force being generated either by an additional spring or by the elastically designed receiving element itself.

In a first variant according to the invention, the receiving element is slidably guided on a holder. Corresponding linear guide means are formed on the holder and the receiving element, such as webs, grooves or other elements that guide a displacement in the longitudinal direction of the rail. In a second variant according to the invention, instead of moving, the receiving element can be held pivotably on the bearing element, especially rotatable. The receiving element can be arranged to be pivotable about both a vertical axis and a horizontal axis.

Preferably, the receiving element is biased towards the fastening means by an additional spring. The spring can then be arranged between the receiving element and a holder.

For optimal positioning of the drawer, a substantially wedge-shaped receptacle for centering the fastening means can be formed on the receiving element. The receptacle can be open at the top and designed as an open, groove-shaped receptacle. On this receptacle, side walls are preferably provided on two opposite sides that are inclined to the longitudinal direction of the rail and center the fastening means on the receiving element. Centering can also be done by aligning the side walls on the receptacle itself at an angle to the vertical, so that the fastening means is inserted centrally between the side walls.

In a further embodiment, the receiving element can comprise a sleeve into which the fastening means is at least partially inserted. Such a sleeve can be slidably mounted on a tubular holder, resulting in a particularly compact structure.

The holder or the bearing element are preferably fixed to a side frame of the drawer. For this purpose, a support can be fixed in the side frame, which is made, for example, from a bent metal sheet and has means for guiding or holding the receiving element on a web protruding from the side frame. Alternatively, the holder or the bearing element can also be fixed to a floor or a rear wall of the drawer.

For simple production, the fastening means can be formed integrally with the rail of the pull-out guide and protrude angularly in a side view. Advantageously, the fastening means can be designed as a hook and then comprises a web projecting upwards from the rail and a web arranged parallel to the longitudinal direction. Alternatively, the fastening means can be fixed as an additional component, for example on a plug or on a cap on the rail.

The device according to the invention for fixing a drawer to a rail of the pull-out guide is used in particular for furniture or household appliances in order to securely attach a drawer to the rail.

A piece of furniture 100 includes a furniture body 101 on which one or more drawers 1 are movably mounted. For this purpose, pull-out guides are provided, which are fixed to the two side walls of the furniture body 2.

Each drawer 1 includes a base 2 and two side frames 3, whereby in Figure 1B Only the rear corner area of the drawer 1 is shown without a rear wall, with the rear wall also being shown in the following Figures 2 - 16 , was waived. The side frame 3 is hollow designed so that means for fastening a rear wall are provided in the interior. Furthermore, a support can be provided in the side frame 3, on which a device for fixing the drawer 1 on a rail 4 of a pull-out guide is arranged.

The rail 4 includes a fastening means, here in the form of a hook 5, which is formed integrally with the rail 4, but can also be manufactured as a separate component. The hook 5 comprises an upwardly projecting web 6 and a web 7 aligned in the longitudinal direction of the rail 4 and facing the drawer 1.

In order to fix the drawer 1 on the rail 4, a receiving element 10 is provided, which is at least partially overlapped by the horizontal web 7 of the hook 5.

In the Figures 2A and 2 B the device for fixing the drawer 1 to the rail 4 is shown without the side frame 3. A support 17 is fixed in the side frame 3 and can be fixed to two angled sections 18 with openings in the side frame, for example by a bolt which passes through the openings in the sections 18. The carrier 17 is made of a bent metal sheet and includes a web 16 which projects inwards from the side frame 3 and to which a holder 14 is fixed. The holder 14 serves for the displaceable mounting of the receiving element 10, on which laterally protruding strips 15 are formed, which engage in corresponding grooves on the holder 14. The linearly guided receiving element 10 is biased towards the back via a spring 13.

If the drawer 1 is to be mounted on the hook 5, the drawer 1 with the receiving element 10 is moved towards the hook 5 until it is in the Figures 3A and 3B shown mounted position is reached. The hook 5 engages with the web 7 over the receiving element 10, and this can be pressed variably into the holder 14 in the longitudinal direction of the rail 4, depending on the length of the drawer 1. The spring 13 is supported at one end on the holder 14 and on the opposite side on the receiving element 10, which is biased towards the hook 5.

The receiving element 10 has a groove-shaped receptacle 11 on its top, which includes two side walls 12 which taper in a wedge shape. This allows the hook 5 to be centered during assembly if the hook 5 is placed off-center on the receptacle 11 of the receiving element 10. The width of the groove-shaped receptacle 11 can also be made smaller in order to be able to achieve a more precise centering of the hook 5 relative to the receiving element 10 during assembly. It is also possible to only use the mount on one side of the drawer as a centering device and to specifically make the mount on the other side of the drawer wider in order to achieve a fixed-floating bearing situation, which can prevent the system from warping due to width tolerances . The same also applies to the centering of the other exemplary embodiments. To make contact easier, the receptacle 11 can have a small sloping surface or a chamfer on the back.

Further exemplary embodiments are described below, in which the same components as in the first exemplary embodiment are designated with the same reference numerals.

In Figure 4 a drawer 1 is shown, in which a modified receiving element 20 is held on the support 17 fixed in the side frame 3, which is not displaceably but rotatably mounted and is gripped by the hook 5.

Like the detailed views of the Figures 5A and 5B show during assembly, a bearing element 27 is formed on the carrier 17 on the inwardly projecting web 16, on which an axle 24 is inserted. On the axis 24, the receiving element 20 is rotatably mounted, which has a groove-shaped receptacle 22 with two upwardly projecting webs 21, which taper downwards in a wedge shape, so that the hook 5 is centered to a certain extent during assembly. The receiving element 20 protrudes in the assembly position with the webs 21 to the hook 5 to the back and can then be pivoted about the axis 24. In the area of the axis 24, at least one spring 23 is provided, which in this exemplary embodiment is designed as a leg spring and is supported with one leg 25 on the web 16 and with the opposite leg 26 on the receiving element 20. The at least one spring 23 biases the receiving element 20 towards the hook 5. The at least one spring 23 can also be fixed to the web 16 by means of an embossing.

If the drawer 1 is mounted, the receiving element 20 moves towards the hook 5, as shown in FIG Figures 6A and 6B is shown. The catch 5 engages with its web 7 over the receiving element 20 and pushes it forward against the force of the spring 23, so that a certain tolerance compensation takes place. The drawer 1 is secured against lifting in the rear area via the hook 5, which engages over the receiving element 20.

In Figure 7 A modified exemplary embodiment is shown in which a drawer 1 has an elastic receiving element 30 which is partially overlapped by the hook 5 on the rail 4. The receiving element 30 is stretched between two pins 31 and 32 and rests on the hook 5 in a central area between the pins 31 and 32.

In Figure 8 the receiving element 30 is shown before assembly when the hook 5 is arranged at a distance. The receiving element 30 is curved towards the back and is wrapped around the pins 31 and 32 at opposite ends. A pin 31 is fixedly arranged on the web 16 of the carrier 17, while the second pin 32 is displaceable on an elongated hole 33 on the web 16. A stop 34 is also provided on the web 16, which is formed on the web 16 by an upwardly bent section and is positioned between the two pins 31 and 32.

If the drawer is now moved relative to the hook 5 to assemble the drawer, the hook 5 with the upwardly projecting web 6 comes into contact with the receiving element 30, and the web 7 engages over the receiving element 30. The receiving element 30 can now be bent for tolerance compensation are, with the pin 32 being moved along the elongated hole 33, as shown in FIG Figures 9A and 9B is shown. The hook 5 then engages over the receiving element 30 in the adjusted position and also the stop 34. The hook 5 can also be securely connected to the drawer via this elastic receiving element 30, which is made, for example, from a bent sheet metal and springs in the longitudinal direction of the rail 4 1 must be connected to prevent the drawer 1 from being lifted in the rear area.

In Figure 10 a fourth exemplary embodiment of a device for fixing a drawer 1 on a hook 5 on the rail 4 is shown, with a receiving element 40 arranged on the web 16 of the carrier 17 being pivotable in order to be able to carry out tolerance compensation in the longitudinal direction of the rail 4.

Like from the Figure 11 As can be seen, the receiving element 40 has a holding section 41 which is fixed to the carrier 17. The holding section 41 is arranged at an angle to the web-shaped receiving element 40, which can be pivoted about a substantially vertical axis. A recess 42 for receiving and centering the hook 5 is formed on the receiving element 40.

Furthermore, a stop 43 is formed on the web 16 of the carrier 17, which also includes a recess 44 which is surrounded by sloping side walls in order to be able to center the hook 5 during assembly.

For assembly, as in the Figures 12 A and 12B shown, the hook 5 moves relative to the drawer 1, wherein the receiving element 40 can be pivoted by the hook 5 until the receiving element 40 rests on the stop 43. The hook 5 covers the receiving element 40 with the web 7 and possibly also the stop 43. Such a pivotable receiving element 40 can also be used to achieve tolerance compensation in the longitudinal direction of the rail 4.

In Figure 13 a further exemplary embodiment of a modified receiving element 50 is shown in order to fix a drawer 1 on the hook 5. The receiving element 50 is designed as a sleeve which is slidably mounted on a sleeve-shaped holder 51. This receiving element 50 can alternatively also be arranged on a rear wall corner connector or directly on a sheet metal rear wall.

Like that Figures 14A to 14C can be removed, the sleeve-shaped holder 51 is held on a web 52 which is fixed to the side frame 3 of the drawer, the rear wall or a floor. The web 52 forms a base on the sleeve-shaped holder 51 and also serves to support a spring 53, which is arranged between the web 52 and the receiving element 50. The receiving element 50 includes an outwardly projecting projection 54 which engages with an inwardly projecting projection 55 on the holder 51, so that the movement of the receiving element 50 is limited by the spring 53.

To mount the hook 5 on the receiving element 50, the hook 5 is moved relative to the receiving element 50 until the web 7, which is aligned parallel to the longitudinal direction of the rail 4, enters the sleeve-shaped receiving element 50 intervenes like this in Figure 15A is shown. Then the hook 5 is securely held on the receiving element 50 and the drawer 1 is secured against being lifted. If the drawer 1 is longer, the receiving element can be pressed into the holder 51, as shown in Figure 15B will be shown. Then the spring 53 is compressed by pressing the receiving element 50 into the sleeve-shaped holder 51, but the hook 5 remains securely held in the receiving element 50 with the web 7.

In Figure 16 is one opposite Figure 13 Modified embodiment shown, in which the receiving element 50 is arranged on the holder 51 as described above, but the holder 51 is not fixed to the side frame, but to a bottom 2 of the drawer 1.

In the Figures 17A and 17B A further exemplary embodiment is shown, in which a receiving element 60 is displaceably arranged on a holder 61. The holder 61 is fixed to a rear wall 9 of the drawer via screws 62. A receptacle for the receiving element 60 is arranged in the holder 61, in which a spring 63 is provided, which biases the receiving element 60 towards the back towards the hook 5. On the receiving element 60 there are outwardly projecting projections 64, which abut on inwardly projecting webs 65 of the holder 61, so that the receiving element 60 cannot fall out of the holder 61. In this exemplary embodiment, the holder 61 can be dimensioned so that it can accommodate additional functions, such as at least one battery for lighting the drawer 1 or elements for tilt adjustment.

For assembly, the hook 5 is moved relative to the holder 61 and can then, as in the Figures 18A-18B shown, press the receiving element 60 into the holder 61. The web 7 of the holder then engages in a channel-shaped receptacle on the receiving element 60, with the spring 63 optionally being compressed in the holder 61, depending on the length of the drawer 1.

The above exemplary embodiments can also be combined with one another as desired. For example, a receiving element can be arranged to be both displaceable and pivotable in order to increase the distance of the movable bearing in the longitudinal direction of the rail. In addition, further means for centering or aligning the hook 5 relative to the receiving element can also be provided or, as described, the centering can only be carried out on one side.
