Description

Device for fixing a drawer

The present invention relates to a device for fixing a drawer on 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.

In DE 202008011 114 U 1, a pull-out guide for drawers is shown in which a hook is integrally formed or fixed on a rail of the pull-out guide. A spring element can be easily seen 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 pull-out guide. So that the pull-out guide can be used for different drawers, the length of the mostly 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 lead to 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 lifting.

EP 1 986523 B1 therefore proposes an adjustable bracket on a rear end of a running rail to set a drawer. The adjustable bracket has a large number of components, so that the assembly and manufacture are complex.

It is therefore the object of the present invention to provide a device for Fixie tion of a drawer on a rail of a pull-out slide that creates a tolerance compensation for manufacturing-related changes in length using simple means.

This object 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 overlapped by the fastening means, is movably held on the drawer and is pretensioned 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 fixed to the rail of the pull-out slide.

In an assembly position, the receiving element is preferably arranged 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 assembled 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 formed receiving element itself.

In a first variant, the receiving element is slidably guided on the holder. Corresponding linear guide means can be formed on the holder and the receiving element, such as webs, grooves or other elements that cause a displacement in the longitudinal direction of the rail. In a second variant, instead of being displaced, the receiving element can be held pivotably on the bearing element, in particular rotatable. The receiving element can be arranged to be pivotable about a vertical axis as well as about a hori zontal axis.

The receiving element is preferably pretensioned 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 on the top and be designed as an open groove-shaped receptacle. On this recording are preferably provided on two opposite sides inclined to the longitudinal direction of the rail formed side walls, which center the fastening means Be on the receiving element. Centering can also take place in that the side walls are inclined on the receptacle itself are aligned to the vertical, so that the fastener 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, so that a particularly compact structure results.

The holder or the bearing element are preferably fixed to a side frame of the drawer. For this purpose, a support can be established in the side frame, which is made for example from a bent sheet metal 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 manufacture, the fastening means can be formed integrally with the rail of the pull-out guide and protrude angularly in a side view. The fastening means can advantageously be designed as a hook and then comprises a web protruding upward 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 stopper or on a cap on the rail.

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

A piece of furniture 100 comprises 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 on the two side walls of the furniture body 2.

Each drawer 1 comprises a base 2 and two side frames 3, with only the rear corner area of the drawer 1 being shown without a rear wall in FIG. 1B, the rear wall also not being shown in the following FIGS. 2-16. The side frame 3 is hollow ausgebil det, so that means for fastening a rear wall are easily seen in the interior. Furthermore, a carrier can be provided in the side frame 3, on which a device for fixing the drawer 1 on a rail 4 egg ner pull-out guide is arranged.

The rail 4 comprises a fastening means, here in the form of a flake 5, which is formed integrally with the rail 4, but can also be made as a separate component. The flake 5 comprises an upwardly protruding web 6 and a web 7 which is aligned in the longitudinal direction of the rail 4 and faces 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 FIGS. 2A and 2B, the device for fixing the drawer 1 on the rail 4 without the side frame 3 is shown. In the side frame 3, a carrier 17 is fixed, which can be fixed to two angled sections 18 with openings in the side frame, for example by a bolt that reaches through the openings in the sections 18. The carrier 17 is made from a bent metal sheet and comprises a web 16 which protrudes inward from the side frame 3 and on which a holder 14 is fixed. The Hal ter 14 is used for the displaceable mounting of the receiving element 10, on which the laterally protruding strips 15 are formed, which engage in the holder 14 in corresponding Nu th. The receiving element 10 guided linearly in this way is biased towards the rear by 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 the mounted position shown in FIGS. 3A and 3B is reached. The hook 5 overlaps the receiving element 10 with the web 7, and this can, depending on the length of the drawer 1, be pressed into the holder 14 in a variable manner in the longitudinal direction of the rail 4. 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 on its upper side a groove-shaped receptacle 11 which comprises two side walls 12 which taper in a wedge shape. As a result, the hook 5 can be centered during assembly if the hook 5 is placed eccentrically on the receptacle 11 of the receptacle element 10. The width of the groove-shaped receptacle 11 can also be made smaller in order to be able to bring about a more precise centering of the hook 5 relative to the receptacle element 10 during assembly. It is also possible to use only the recording on one side of the drawer as a centering and to make the recording on the other side of the drawer specifically wider in order to obtain a fixed-floating bearing situation that prevents the system from becoming warped due to width tolerances can. The same also applies to the centering of the other exemplary embodiments. For easier contacting, the receptacle 11 can have a small inclined surface or a bevel on the rear.

Further exemplary embodiments are described below in which the same components as in the first exemplary embodiment are denoted by the same reference numerals. In Figure 4, a drawer 1 is shown in which a modified receiving element 20 is held on the fixed in the side frame 3 support 17, which is not displaceable, but rotatably mounted and is 5 Übergrif fen by the hook.

As the detailed views of FIGS. 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 downward 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 rear and can then be pivoted about the axis 24. In the area of the axis 24, at least one spring 23 is provided, which is designed as a leg spring in this embodiment and is supported with one leg 25 on the web 16 and with the leg 26 opposite GE 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 on the web 16 by means of a stamping.

When the drawer 1 is mounted, the receiving element 20 moves towards the hook 5, as shown in FIGS. 6A and 6B. The hook 5 overlaps with its web 7 the receiving element 20 and presses this ge against the force of the spring 23 forward, 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 embodiment is shown in which a drawer box 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 rear and is wound around the pins 31 and 32 at opposite ends. A pin 31 is fixed to the web 16 of the carrier 17 arranged, while the second pin 32 is displaceable at an elongated hole 33 on the web 16. On the web 16, a stop 34 is also provided, which is formed on the web 16 by a section bent upward 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 overlaps the receiving element 30. The receiving element 30 can now be used to compensate for tolerances be bent, the pin 32 being displaced along the elongated hole 33, as shown in FIGS. 9A and 9B. The hook 5 then overlaps the receiving element 30 in the adjusted position and also the stop 34. The hook 5 can also be securely connected to the Drawer 1 are connected to prevent the drawer 1 from lifting in the rear area.

FIG. 10 shows a fourth exemplary embodiment of a device for fixing a drawer 1 to a hook 5 on the rail 4, a receiving element 40 arranged on the web 16 of the carrier 17 being pivotable in order to compensate for tolerances in the longitudinal direction of the rail 4 to be able to.

As can be seen from FIG. 11, the receiving element 40 has a half 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 an essentially 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 comprises a recess 44 which is surrounded by inclined side walls in order to be able to center the hook 5 during assembly.

For assembly, as shown in FIGS. 12A and 12B, the hook 5 is moved relative to the drawer 1, the receiving element 40 being able to be pivoted by the hook 5 until the receiving element 40 rests against the stop 43. The hook 5 covers the web 7 on the receiving element 40 and possibly also the stop 43. Also by a Such a pivotable receiving element 40 can be used to implement a tolerance compensation in the longitudinal direction of the rail 4.

FIG. 13 shows a further exemplary embodiment of a modified receiving element 50 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 hülsenförmi gene holder 51. This receiving element 50 can alternatively also be arranged on a rear wall connector or directly on a sheet metal rear wall.

As can be seen in FIGS. 14A to 14C, the sleeve-shaped holder 51 is held on a web 52 which is fixed on 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 comprises an outwardly projecting projection 54 which is in engagement 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 aligned parallel to the longitudinal direction of the rail 4 engages in the sleeve-shaped receiving element 50, as shown in FIG. 15A. Then the hook 5 is securely held on the receiving element 50 and the drawer 1 secures ge against lifting. If the drawer 1 is made longer, the receiving element can be pressed into the holder 51, as shown in FIG. 15B. Then, by pressing the receiving element 50 into the sleeve-shaped Hal ter 51, the spring 53 is compressed, but the hook 5 remains securely held with the web 7 in the receiving element 50.

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

A further exemplary embodiment is shown in FIGS. 17A and 17B, in which a receiving element 60 is arranged displaceably on a holder 61. The holder 61 is on screws 62 on a rear wall 9 of the drawer set. 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 rear towards the hook 5. On the receiving element 60 there are outwardly protruding projections 64 which abut against inwardly projecting webs 65 of the holder 61 so that the receiving element 60 cannot fall out of the holder 61. In this embodiment, the holder 61 can be dimensioned so that additional functions, such as, for example, at least one battery for illuminating the drawer 1 or elements of an inclination adjustment can be accommodated.

For assembly, the hook 5 is moved relative to the holder 61 and can then, as shown in FIGS. 18A-18B, 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, 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 both displaceably and pivotably 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.
