Description

The present invention relates to a pull-out runner for a drawer, with a guide rail that can be fixed to a body and a running rail that can be moved relative to the guide rail, between which at least one center rail that extends the extension is optionally provided, with a holding device for fixing a drawer being provided on the running rail, which comprises a projection that can be inserted into a receptacle on the drawer, with a height adjustment and a side adjustment being provided on the holding device for changing the position of the drawer relative to the runner, and a method for aligning a drawer on a pull-out guide.

the DE 10 2015 106 789 A1 discloses a pull-out guide for a drawer, in which a holding device is provided on a running rail. The holding device comprises a projection which can be inserted into a socket on the drawer. The projection of the holding device can be adjusted via a first lateral adjustment device and a second vertical adjustment device. The device for lateral adjustment comprises a knurled nut which can be rotated about a horizontal axis, and the device for height adjustment comprises a knurled nut which can be rotated about a vertical axis. Although the adjustment mechanism enables an exact positioning of the projection by adjusting the side and height, the adjustment mechanism comprises a comparatively large number of individual parts.

It is therefore the object of the present invention to create a pull-out guide for a drawer with a holding device for fixing a drawer in place, which enables the drawer to be aligned in a simple manner with a compact design. In addition, an effective method for aligning a drawer is to be provided.

This object is achieved with a pull-out guide having the features of claim 1 and a method having the features of claim 12.

The pull-out guide according to the invention comprises a holding device with a height adjustment and a side adjustment for changing the position of the drawer relative to the runner, with an actuating element is provided, by means of which a height adjustment and a lateral adjustment can be carried out. As a result, both a vertical adjustment and a lateral adjustment can be made with one and the same adjustment element, so that no two different adjustment elements have to be provided for the different adjustment movements. This reduces the number of components required and enables a compact design.

According to the invention, the adjusting element brings about a vertical adjustment in a first position and a lateral adjustment in a second position, which is adjusted relative to the first position. According to the invention, the adjusting element is designed as an adjusting spindle which can be displaced between the first position and the second position. The adjusting spindle is therefore axially adjustable in order to be moved from a first position for height adjustment to a second position for lateral adjustment, and vice versa. The adjusting element or the adjusting spindle can have a profile which extends in the axial direction and which engages in a threaded sleeve with an inner profile in an axially displaceable manner. As a result, the threaded sleeve can be rotated in a first position by engaging the profiling, while in a further position the profiling of the adjusting element is pulled out of the inner profiling so that the threaded sleeve no longer moves when the adjusting element or the adjusting spindle is rotated.

In one embodiment of the invention, the holding device comprises a height-adjustable support element on which the drawer is supported. The support element can have an eyelet with an internal thread, which is in engagement with a rotatable threaded sleeve. By turning the threaded sleeve or a threaded bolt, the support element can then be adjusted in the vertical direction to align the pusher bar. The use of a thread has the advantage that after a rotary movement of the threaded sleeve or the threaded bolt, the thread can be self-locking, ie the support element no longer moves in the vertical direction if the threaded sleeve or the threaded bolt is not rotated.

The holding device can also have a horizontally movable slide, by means of which the projection can be moved horizontally in order to carry out a lateral adjustment. The slide can have a pin on which the projection is held, so that the projection is positioned in the horizontal direction by moving the slide. The slider can be locked in different positions, so that a set position is maintained.

In a further preferred embodiment, a projection of the holding device is designed to be resiliently elastic. As a result, when the drawer is adjusted relative to the running rail, the projection can be carried along, so that an adjustment mechanism can act directly on the drawer. In the case of a vertical adjustment, the projection can thus be carried along passively, while the active adjustment takes place on a support element for the drawer. In the case of lateral adjustment, the projection can optionally be actively adjusted, in particular via a slide that can be moved horizontally. Even then, it is possible to utilize the elasticity of the projection by arranging at least one holding portion formed integrally with the projection in a stationary manner and only moving the slider with the projection.

The projection is preferably made from a bent wire. The projection can have an eyelet which is rotatably mounted about a pin, in particular a pin arranged on a slide, by means of which a lateral adjustment can be carried out.

In the method according to the invention for aligning a drawer, the drawer is first positioned in such a way that a projection of a holding device engages in a receptacle on the drawer. An adjusting element for aligning the drawer relative to the running rail is then moved in a first direction, and then the adjusting element is adjusted from a first position to a second position in order to then use the same adjusting element to align the drawer with the running rail in a second direction to effect, which deviates from the first direction. This allows the actuating element to be used for an adjustment process in different directions, which simplifies handling. The projection is preferably elastically bent relative to the running rail during an adjustment process of the drawer, preferably in the vertical direction.

A drawer 1, for example for furniture or household appliances, comprises a front wall 2, a rear wall 3 and two side walls 4, as is shown in figure 1 is shown. In the lower area of the rear wall 3, two recesses 5 are formed, into which a running rail 7 of a pull-out guide 6 can be at least partially inserted. Optionally, the recess 5 can also be omitted. Two receptacles 9 are provided in the rear wall 3, into which a projection of a holding device 10 can be inserted in order to align and fix the drawer 1 relative to the pull-out guide 6.

The pull-out guide 6 comprises a movable rail 7 which is optionally held directly on a stationary guide rail or on a central rail 8 which can also be moved between the guide rail and the running rail 7 .

The drawer 1 can be adjusted via the holding device 10 both in the vertical direction, ie in height, and in the horizontal direction, ie laterally. The inclination of the front or a front panel of the drawer 1 is adjusted by means of the height adjustment in the rear area of the drawer 1 . One or two holding devices 10 can be provided on the rear wall 3 . Only one holding device 10 is described below, which can also be provided on the opposite side of the drawer 1 in the same manner. Alternatively, a holding device can also be provided on the other side of the drawer 1, which only has a height adjustment.

The holding device 10 is in the Figures 3A and 3B shown without pull-out guide 6 and drawer 1. The holding device 10 comprises a holder 11 which can be fixed to an upper side of the running rail 7 . For this purpose, two protruding flanges 12 with openings 13 for fastening means are provided on the bottom side of the holder 11 . A support element 40 is provided on the holder 11 , which essentially surrounds the block-shaped holder 11 in a U-shape, with two legs 42 being connected to one another via a wall 41 . Two webs 43 and 44 are provided integrally with the wall 41 and form a support for the drawer 1, the webs 43 and 44 having a tapered starting bevel in order to make it easier for the drawer 1 to be slid open. The support element 40 can be displaced in the vertical direction relative to the holder 11, but cannot be displaced in the horizontal direction via the legs 42.

Also provided on the holder 11 is an actuating element 20 which protrudes over the holder 11 with a rotatable head section 21 . The adjusting element 20 can be rotated as well as adjusted in the axial direction.

The holding device 10 also includes a projection 30 which can be inserted into a receptacle 9, in particular a bore on a rear wall 3 of the drawer 1. The protrusion 30 includes an eyelet 32 which is held on a pin 51 of a slider 50 . The slider 50 can move in the horizontal direction be adjusted in order to bring about a movement of the drawer 1 relative to the running rail 7 .

In the Figures 4A and 4B the holding device 10 is shown with the individual parts in an exploded view. The actuator 20 includes a head portion 21 protruding from the holder 11 . The holder 11 comprises an upper U-shaped section 18 with a bearing opening 19 into which a cylindrical section 22 of the actuating element 20 is inserted. A cylindrical section 23 with a smaller diameter adjoins the cylindrical section 22 with a larger diameter. This cylindrical section 23 with a smaller diameter is passed through a passage 16 on the holder 11 which is formed between two webs 15 projecting inwards. The webs 15 are arranged above a receptacle 14 in which a threaded sleeve 26 is rotatably arranged. The receptacle 14 is designed to be open towards the rear, with an eyelet 45 of the support element 40 engaging in the receptacle 14 and having an internal thread 46 . The internal thread 46 engages with the external thread of the threaded sleeve 26.

Below the cylindrical section 23 with a smaller diameter, the actuating element 20 comprises a profiling 24 which is arranged in an axially displaceable manner. Below the profiling 24 there is also an optionally provided drive section 25 with profiling, which has a smaller diameter than the profiling 24. In this exemplary embodiment, the drive section 25 engages with the inner profiling of the threaded sleeve 26 and can therefore rotate it. Alternatively, the internal thread of the threaded sleeve 26 can also be designed in such a way that the profile 24 engages with the internal profile. In this case, the actuating element 20 can be designed without a drive section 25 .

The projection 30 is made from a bent wire, in particular a spring steel wire, which can be bent elastically. At its front end, the projection 30 comprises an arc 31 which is arranged in the receptacle 9 of the drawer 1 in the assembled state. A bent eyelet 32 is formed integrally with the projection 30 and engages a pin 51 on a slider 50 . A groove-shaped recess 52 is provided on the pin 51 , which at least partially encompasses the eyelet 32 , so that when the slider 50 moves, the eyelet 32 is displaced together with the pin 51 .

The eyelet 32 is also connected to an angled bracket which has a substantially vertical section 33 and a horizontal section 34 on which an end hook 35 is formed. The hook 35 is inserted at an underside of the holder 11 and fixed there via the holder 11 in the vertical direction and movably supported in the horizontal direction.

The slider 50 includes a frame 53 in which an elongated hole 54 is recessed. A toothing 55 is provided on an inner wall of the elongated hole 54 and can engage with the profile 24 of the actuating element 20 . Ribs 56 are also formed on the underside of the frame 53 and can engage with teeth 57 on the receptacle 17 of the holder 11 . The receptacle 17 on the holder 11 is delimited on the bottom by the webs 15 and on the top by the section 18 . The ribs 56 extend with their longitudinal direction perpendicular to the direction of movement of the slider 50, which is laterally adjustable horizontally. For such an adjustment movement, the actuating element 20 can be raised, so that by rotating the actuating element 20 the profile 24, which is in engagement with the teeth 55, causes a movement of the slide 50 in the lateral direction. Such a movement of the slide 50 in the lateral direction also moves the eyelet 32 laterally via the pin 51 and thus causes a movement of the projection 30 in the lateral direction. The set position of the slide 50 is fixed via the ribs 56 and the teeth 57.

In the Figures 5A and 5B For example, the holding device 10 is shown in a position in which the support element 40 and the projection 30 are arranged in a lower position. The adjusting element 20 is also in a lower position, and the profile 24 of the adjusting element 20 is in engagement with the threaded sleeve 26. Its external thread is in engagement with the eyelet 45 of the support element 40, and by turning the head section 21 of the adjusting element 20, the Threaded sleeve 26 are rotated, which due to the non-rotatable arrangement of the support element 40 means that the eyelet 45 is raised or lowered together with the support element 40 in the receptacle 14. In figure 6 the actuating element 20 is also shown in a lower position, but without the support element 40. On the underside of the holder 11, the hook 35 is held stationary in a receptacle.

In the Figures 7A and 7B the holding device is shown with a section through the actuating element 20 . The actuating element 20 passes through the section 18 with the cylindrical section 22 and is connected to the cylindrical section 23 smaller diameter through the slide 50 and the implementation 16 out. The drive section 25 is in engagement with a lower section of the threaded sleeve 26 and the profile 24 is held in a receptacle of the threaded sleeve 26 . The threaded sleeve 26 is supported on a bottom of the receptacle 14 of the holder 11 and cannot be adjusted in height due to the web 15 . By turning the threaded sleeve 26 by the adjusting element 20, the non-rotatably arranged eyelet 45 of the support element can be raised or lowered. Furthermore, the actuating element 20 can be raised so that the form-fitting engagement between the profile 24 and the profile on the threaded sleeve 26 is canceled and the profile 24 is now in engagement with the teeth 55 on the slide. In this position, a side adjustment can be made by rotating the adjusting element 20 of the slider 50 is displaced.

In the Figures 8A and 8B the holding device 10 is shown on the running rail 7 in a mounted position, with the support element 40 being arranged in a lowered position and the supports on the webs 43 and 44 protruding only slightly or not at all from an upper side of the running rail 7 . The web 43 is accommodated in a slot 70 on the upper side of the running rail 7 . If the drawer 1 is now to be raised relative to the running rail 7, the adjusting element 20 is rotated on the head section 21, so that the supporting element 40 is raised, as is shown in FIG figure 9 is shown. As a result, the webs 43 and 44 move upwards, and the projection 30 is bent upwards by the movement of the drawer 1 with the receptacle 9, i.e. it is carried along with the drawer 1.

In figure 10 the holding device 10 is shown with the upwardly bent projection 30 in a side view. The previously essentially horizontally aligned web is now bent upwards by an angle of between 10° and 20°, with the projection 30 being designed as a bent wire which can be elastically deformed.

If a side adjustment is to be made, according to figure 11 the actuator 20 are pulled out upwards, so that the head portion 21 above the holder 11 protrudes more than in the Figures 8 to 10 . In this position, the profile 24 of the actuating element 20 is in engagement with the teeth 55, and by turning the head portion 21, a lateral adjustment can be made, as is the comparison of FIG figures 11 and 12 displays. By turning the adjusting element 20, the slide 50 is now in shifted horizontal direction, wherein the projection 30 is held with the eyelet 32 on the pin 51 and is carried along with the slide 50. With the movement of the slider 50, the angled holding portion, which is formed integrally with the projection 30, is moved laterally accordingly. The movement of the projection 30 results in a lateral adjustment of the drawer 1 relative to the running rail 7.

In figure 13 the holding device is shown in the lateral adjustment position in a rear view. The eyelet 32 is held on the pin 51 and is moved together with the hook 35 which is mounted on the underside of the holder 11. As a result, the eyelet 32 and the projection 30 always maintain a vertical orientation. Alternatively, the hook 35 could be fixed in the holder 11 both in the vertical and in the horizontal direction. In this case, the eyelet 32 would move relative to the hook 35 and the projection 30 would therefore no longer have a vertical alignment. So it would be bent sideways.

When the desired lateral position of the drawer 1 is adjusted, the ribs 56 and teeth 57 engage, thus ensuring that the adjusted position does not change. The height of the ribs 56 and teeth 57 is less than that of the teeth 55 and profile 24, so that an adjustment can be carried out without great effort.

If a height adjustment is now to be made, the adjusting element 20 can be pushed back into the holder 11, as shown in figure 14 is shown. The head section 21 of the adjusting element 20 can then be rotated in order to lower or raise the support element 40 again and to align the drawer 1 relative to the running rail 7 accordingly. In FIG. 16, the actuating element 20 is shown in a raised position with the projection 30 lowered, while in figure 15 the actuating element 20 is lowered. In figure 17 is the slider 50 compared to figure 13 been adjusted to the right, and the actuator 20 is in the lowered position. A vertical adjustment as well as a lateral adjustment can thus be made via an adjusting element 20 .
