EXTENSION GUIDE FOR A DRAWER The present invention relates to a pull-out guide for a drawer, with a guide rail which can be fixed to a body and a movably mounted running rail, wherein at least one central rail can optionally be provided between the guide rail and running rail, and a fastening device with on the running rail a holder is provided on which a drawer can be fixed, means for adjusting the side of the drawer relative to the running rail being provided on the fastening device and / or the drawer.

WO2011094780 A1 discloses a pull-out guide for drawers in which a holding lug is provided on the side of a slide rail, which can be inserted into an opening on the drawer. A disadvantage here is the parallel axis alignment of the rotary movement of the adjusting device to the pull-out rail, with this arrangement reducing the volume of the drawer.

Conventional pull-out guides are known for example from WO 2011094780 A1, WO 2012149588 A1, DE 202006003035 U1, EP 1785062 A1 and DE 202007014954 U1.

A disadvantage of these pull-out guides, however, is that the holders of the adjustment mechanisms can only be moved in translation.

It is therefore an object of the present invention to provide a pull-out guide for a drawer in which the drawer is laterally adjustable in the rear area and at the same time provides maximum storage space.

This object is achieved with an extract guide with the features of claim 1. According to the invention, a fastening device with a holder is provided on the running rail, on which a drawer can be fixed, the holder being adjustable in a horizontal direction perpendicular to the longitudinal direction of the running rail. As a result, the positioning of the drawer in the horizontal direction can be adjusted by the holder, for example in order to compensate for manufacturing tolerances in the width of the drawer and / or to obtain an optimal front panel image. The adjustment can also be used to clamp the drawer to the fastening device. The holder is arranged so as to be pivotable about an axis in the horizontal direction. A lateral adjustment can be carried out by moving the holder at least partially in a direction perpendicular to the longitudinal direction of the running rail.

Preferably, the means for adjustment are infinitely adjustable, in particular with an eccentric, an adjusting screw or a curve guide. It is also possible to gradually change the adjustment e.g. via a locking mechanism, in particular locking pawls.

For a stable attachment of the drawer, the holder has an upper projection which can be inserted into a receptacle or a holding device on a rear wall of the drawer, and a lower guide section which can be moved along a guide, in particular in one direction essentially parallel to the longitudinal direction of the running rail. The guide with the holder or the holder can be pivotable about a vertical bearing axis in order to make a lateral adjustment.

For the lateral adjustment, an adjusting eccentric, a curve guide or another mechanism can be provided in order to adjust the holder in the horizontal direction perpendicular to the longitudinal direction of the running rail.

Preferably, the holder is mounted displaceably in the longitudinal direction of the running rail and biased forward in the pull-out guide via an energy store. If a drawer becomes / 30

AT515 638 B1 2019-07-15 Austrian

Mounted by the patent office of the running rail, the holder is moved against the force of the energy accumulator to the back of a furniture body, so that manufacturing tolerances of the drawer in the pull-out direction, the guide rail or the running rail can be compensated. In addition, tolerances in components of the fastening device cannot have a negative effect on the assembly. Due to the displaceable mounting of the holder, a depth adjustment in the longitudinal direction of the running rail can also be carried out in a simple manner, since the holder is mounted displaceably anyway, so that the drawer is adjustably fixed to the holder in this direction by a suitable adjusting device. In addition, the drawer can be held in a substantially non-positive manner in the direction of the running rail on the running rail by the pretensioning of the holder, so that a disturbing play is avoided. Moving the holder also makes assembly easier, since the user feels during assembly whether the drawer has been correctly brought into engagement with the holder and is being moved.

For a simple assembly of the fastening device, a guide for the holder can be provided, which is held on the side of the running rail. As a result, the height is not adversely affected by the fastening device.

For a compact structure, the slidable holder can have an upper projection which can be inserted into a receptacle or a holding device on a rear wall of the drawer, and a lower guide section which can be moved along a guide. As a result, the holder has an essentially U-shaped construction and can be produced as a bent metal sheet or plastic part.

To fix the drawer, additional fasteners can be provided on the running rail in addition to the movable holder, so that the drawer can be locked on the running rail and is secured against lifting. The drawer can be mounted on the holder without tools, which makes it easier to remove and put on the drawer.

The holder is preferably biased by a spring which is tensioned between a housing of the fastening device and the holder. The spring can be designed as a tension, compression or roller spring, in particular as a coil spring.

For a height adjustment of the drawer relative to the running rail, a support for the drawer, the holder and / or a holding device on the rear wall of the drawer can be adjustable in height. The height adjustment changes the position of the drawer relative to the running rail, and the height adjustment can also be used to adjust the inclination on the front panel.

According to a further embodiment of the invention, the holder is displaceable along a guide which is oriented inclined to the horizontal. This configuration enables the drawer to be fixed in a clamped manner on the running rail or a component connected thereto, the guide preferably dropping downward and, as a result, clamping forces can be applied to the drawer perpendicular to the longitudinal direction of the running rail when the holder is moved. This enables a particularly stable fixation of the drawer.

The pull-out guide according to the invention is used in particular in furniture or household appliances in order to fix a drawer between two pull-out guides.

The invention is explained in more detail using several exemplary embodiments with reference to the accompanying drawings. Show it:

Views of another embodiment of a pull-out guide for a drawer.

A drawer 1 comprises a front panel 2, a rear wall 3 and side walls 4, which connect the front panel 2 and rear wall 3 to one another. Furthermore, a base 5 is provided, it being possible for the front panel 2, rear wall 3, side walls 4 and base 5 to be made of wood, metal or another material.

On the rear wall 3, two recesses 6 are provided, on each of which a pull-out guide 8 is mounted. Furthermore, an opening 7 is provided in the rear wall 3 above the recess 6, into which a projection 22 of a holder 21 can be inserted in order to fix the drawer 1 to a running rail 10 of a pull-out guide 8. The pull-out guide 8 can be designed as a full extension and have a guide rail 9 which can be fixed to a body and a central rail 11 on which the running rail 10 is movably mounted. On the running rail 10, a fastening device 20 is also fixed in the rear area, on which the holder 21 is slidably mounted.

For assembly, the drawer 1 is first placed with the bottom 5 on the two rails 10 on opposite sides and then moved to the rear until the projection 22 on the holder 21 engages in the opening 7, as shown in Figures 2A and Figure 2B. Subsequently, the drawer 1 is moved further back against the force of a spring or other energy storage device, which prestresses the holder 21 towards the front. The drawer 1 can then be fixed to the running rail 10 via fastening means (not shown in more detail), for example by latching. Such devices for fastening a drawer to the running rail are known, for example, from DE 10 2013 104 829 and can be provided with a depth adjustment for the drawer.

The fastening device 20 is shown in Figures 3 and 4 in detail.

The fastening device 20 comprises in the upper region a pin-shaped projection 22 oriented towards the front and a web 23 arranged underneath, which can be moved linearly along a guide 50. The sliding path is limited at the rear by a rear wall 53 on the guide 50 and at the front by a cover 62 which is locked on the guide 50. The guide 50 forms a groove 51, on the side walls of which there are inwardly projecting teeth 52 which are in engagement with teeth 25 of the holder 21 when the holder 21 has been pushed backwards in the guide 50. In the front area of the guide 50, no teeth 52 are provided on the side walls of the groove 51.

The holder 21 is biased in the opening direction by an energy accumulator in the form of a spring 28 which is designed as a helical spring. One end 27 of the spring 28 is fixed to a receptacle 26 of the holder 21 on the web 23.

An opposite end 29 of the spring 28 is held on an angled section 31 of a housing 30 of the fastening device 20, a receptacle 32 for inserting the end 29 being provided on the section 31 for this purpose. Alternatively, the opposite end 29 of the spring 28 can also be held indirectly or directly on the running rail, for example on an angle piece integrally formed from the running rail.

By biasing the holder against the drawer, there is an improved force on the projection 22 of the holder 21. The holder 21 is pressed by spring force against the drawer rear wall, so that almost no bending moment on the

Patent office

Projection 22 acts.

The fastening device 20 is designed such that an adjustment of the drawer 1 is possible both in height and in the lateral direction.

A depth adjustment parallel to the longitudinal direction of the running rail 10 is also possible.

For a height adjustment, a slide 46 is provided on the housing 30, which has slots 47 oriented at an angle to the horizontal. Pins 48 are arranged in the elongated holes 47 and are fixed to openings 35 in a web 34 of the housing 30. A rear wall 33 is provided at the end of the web 34. In order to adjust the height of the slide 46, there is a knurled nut 38 on the housing 30 with an internal thread, which is stationary between two bent tabs 36 in the axial direction, but is rotatably mounted on bearings 37. A threaded bolt 39 is arranged in the knurled nut 38, which test rotates but is axially displaceable. The threaded bolt 39 is connected to a block 40 with a lever 43, a bendable pivot pin 42 being provided on the lever 43, which can be locked in an opening 41 of the block 40. On the opposite side, the lever 43 is locked in an opening 45 on the slide 46 via a bendable pivot pin 44. If the knurled nut 38 is rotated, the threaded bolt 39 moves in the axial direction and pulls or pushes the lever 43 accordingly in order to move the slide 46. The slider 46 is moved obliquely to the horizontal via the guide of the two elongated holes 47 on the pin 48, and thereby an upper contact surface of the slider 46 is moved up or down relative to the housing 30 and the running rail 10. Since the drawer 1 is supported with the bottom 5 or the side wall 4 on the bearing surface of the slide 46, the height position of the drawer 1 is thus set relative to the running rail 10.

During assembly, the drawer is first moved to the projection 22 on the holder 21. The holder 21 for receiving the drawer 1 on the running rail 10 is tensioned in front by a spring, so to speak in a waiting position at a front stop. The height of the holder 21 is predetermined. The drawer is then placed on the running rail 10, and the holder 21 is first pushed into its final end position together with the drawer. This end position can vary depending on the tolerance. Nevertheless, the connection of the holder 21 to the drawer by the spring force is perfect in every end position situation.

The height adjustment of the slider 46 is independent of the projection 22 and the holder 21. Is usually adjusted when the drawer is removed.

It can be seen in FIG. 1 that the knurled nut 38 cannot be reached when the drawer is partially pushed open.

For height adjustment, the drawer 1 is released from the front fastening device on the running rail 10 and pulled down over a distance of about 10 cm from the holder / the running rail, still partially resting on the running rail. Now you have access to the knurled nut 38. The height of the slide 46 can then be adjusted via the knurled nut 38. The drawer 1 is then moved back again until the opening 7 meets the holder 21. If the projection 22 is fully inserted into the opening 7, the holder 21 moves together with the drawer counter to the spring force. This then hits the inclined ramp of the slide 46 with its bottom and runs the incline up to the other height level. The holder 21 is taken along (also in terms of height). When driving on, teeth 25 of the holder engage teeth 52 of guide 50 and thus prevent the drawer from being lifted upward.

The height adjustment in this embodiment is therefore not carried out when the drawer is mounted, but when the drawer is at least partially dismantled.

The fastening device 20 also allows lateral adjustment of the position of the drawer 1. For this purpose, the guide 50 is pivotally mounted on the housing 30. The guide 50 is designed as a lever, at one end 54 of which a bearing sleeve 55 is provided

AT515 638 B1 2019-07-15 Austrian

See patent office, which is penetrated by a vertical journal 56. The vertical bearing pin 56 is also rotatably mounted on a bearing opening 57 on the housing 30. In a central region of the guide 50, a threaded opening 58 is formed on a web, in which a threaded bolt 61 of a screw 60 is screwed. The screw 60 comprises a gap between a ring 67 and a screw head, on which a wall of the housing 30 is inserted adjacent to a slot 59, so that the screw 60 is held on the housing 30 so that it cannot be displaced in the axial direction. If the screw 60 is now turned, the distance between the wall of the housing 30 with the slot 59 and the guide 50 changes. As a result, the guide 50 pivots about the bearing pin 56, as a result of which the position of the holder 21 changes in a horizontal direction perpendicular to the longitudinal direction the track 10 changes.

When the drawer 1 is removed, the holder 21 is to be prevented from being removed from the guide 50. Therefore, a cover 62 is provided on the guide 50 in the front area, which is locked on the guide 50. The cover 62 is essentially U-shaped, two webs 63 being provided on both legs of the U, one web of which has an opening 64. When the cover 62 is slipped onto the two webs of the guide 50, a locking projection 65 on a web enters the opening 64 and thus prevents the cover 62 from being inadvertently removed. The holder 21 can therefore only reach the cover 62 when the drawer 1 is removed be moved, which serves as a stop and prevents the holder 21 can be removed and dismantled upwards.

In Figure 5, the fastening device 20 is mounted on the pull-out guide 8. As can be seen in the sectional view of FIG. 6, the teeth 25 on the holder 21 are in engagement with the teeth 52 on the guide 50. Although this enables the holder 21 to be moved linearly on the guide 50, it does not lift or Lowering. In addition, the guide 50 can be pivoted to a certain extent within the housing 30 about the bearing journal 56, so that the holder 21 can also be adjusted laterally. If the pull-out guide 8 is in the extended position, the adjustment processes can be carried out by hand without tools, since the screw 60 and the knurled nut 38 are accessible from the outside. This enables a comfortable setting of the position of the drawer 1.

As shown in Figure 6, for a good guidance in the longitudinal direction, a vertically downward web 24 is guided on the holder 21 in a groove 66 of the guide 50.

In Figure 8, the drawer 1 is shown during assembly, in which the projection 22 is inserted into the opening 7 on the rear wall 3. The drawer 1 is now pushed further back until the rear wall 3 moves the holder 21 backwards, as shown in FIG. 9. As a result, the spring 28 is further tensioned until the desired end position is reached. For this purpose, the holder 21 can be moved up to the rear wall 53 on the guide 50, but a position from the rear wall 53 can also serve as the end position.

In this and the following exemplary embodiments, the same reference numerals are used for the same components, so that only the modified components are described in detail.

FIGS. 10 to 17B show a further embodiment of a fastening device 80 which is used to fix a drawer 1 to a running rail 10. The fastening device 80 comprises a displaceable holder 81 which can be inserted into an opening 7 on the rear wall 3 of the drawer 1 in order to fix it to a running rail 10 on opposite sides. In Figure 11, the fastening device 80 is shown in the assembled position.

In Figures 12A and B, the fastening device is shown without drawer 1, and it can be seen that the holder 81 has a projection 82 pointing in the opening direction, which can be inserted into the opening 7. The holder 81 is essentially C-shaped and comprises a lower web 83 which is slidably mounted on a holding web 100

5/30

AT515 638 B1 2019-07-15 Austrian

Is patent office. The holding web 100 is fixed to the running rail 10 with a section 101, for example by welding or gluing. On the holding web 100, a pin 86 projecting upward is fixed with a widened head section, which extends through an elongated hole 85 in the lower web 84 of the holder 81. As a result, the holder 81 is slidably mounted on the holding web 100. Between the holding web 100 and the holder 81, a spring 94 is tensioned, which is designed as a tension spring and is held at one end on the holding web 100 fixed to the running rail 10 and on the opposite side on a projection of the holder 81.

The holder 81 can also be adjusted in a direction horizontally and perpendicular to the longitudinal direction of the running rail 10. For this purpose, an upper web 84 is provided on the lower web 83, which rests in regions on the web 83 and is also displaceably guided on the pin 86 and the holding web 100 and has an elongated hole 85. In an area adjacent to the spring 94, an eccentric 87 is provided, by means of which the upper web 84 can be pivoted about the pin 86 relative to the lower web 83. The upper web 84 is held by a nose 90 which fixes the upper web 84 in the lateral direction. For this purpose, a slot-shaped recess 98 with a vertical section 89 is provided on a vertical section of the upper web 84 and the lower web 83, through which a tip of the nose 90 is guided. On the upper web 84, inward projections 88 are provided in the region of the nose 90, so that the upper web cannot be displaced in the lateral direction. If the eccentric 87 is now adjusted, the upper web 84 can be held by the nose 90, while the lower web 83 is pivoted laterally with the holder 81.

Furthermore, a height adjustment for the nose 90 is provided, which is integrally formed with a vertical plate 91. The vertical plate 91 is slidably supported on a support plate 92, the support plate 92 being connected to the running rail 10. The running rail 10 has a cutout 96 on a side wall, into which a web 97 of the support plate 92 engages. The support plate is preferably welded to the running rail 10. Furthermore, the support plate 92 engages around the outer contour of the running rail 10, so that the running rail 10 and the supporting plate 92 form a fixed unit. A plurality of vertical elongated holes 95 are recessed on the support plate 92 and are penetrated by pins 99 which are fixed to the plate 91. Furthermore, an eccentric 93 is fixed to the plate 91, which is rotatably mounted and, when rotated, displaces the plate 91 in the vertical direction relative to the support plate 92, as a result of which the nose 90 is raised or lowered. As an alternative to the eccentric 93, a flat thread spindle can also be used.

The side adjustment is shown in Figures 13A and 13B in plan view and Figures 14A and 14B in a rear view. In FIGS. 13A and 14A, the holder 81 is arranged with a gap A to the running rail 10. By rotating the eccentric 87, the holder 81 pivots about the bolt 86 and the holder 81 with the lower web 83 is pivoted toward the running rail 10, as shown in FIGS. 13B and 14B. As a result, the drawer 1 can be appropriately aligned relative to the running rail 10.

The height adjustment of the fastening device 80 is shown in FIGS. 15A and 15B. By rotating the eccentric 93, the plate 91 is adjusted in height relative to the support plate 92, the lowered position being shown in FIG. 15A and the raised position in FIG. 15B. By moving the vertical plate 91 relative to the support plate 92, the nose 90 is raised or lowered accordingly.

FIGS. 16A and 16B show the situation in which the holder 81 bears against its front stop in a prestressed manner and the drawer has already been pushed onto the projection 82 by means of its opening 7. A section through the fastening device 80 is shown, in which the arrangement of the eccentric 87 in the region of the lower web 83 and the upper web 84 can be seen. In addition, it is shown in FIG. 17B that the holding web 100 has a section 103 which is angled downwards towards the rear and which is at an angle between 2 ° and 20 °, in particular 5 ° to 10 °, to the horizontal.

6/30

AT515 638 B1 2019-07-15 Austrian

Patent Office is inclined and forms an inclined plane. As a result, the holder 81 can be raised when the lower web 83 is moved in the horizontal direction. The lower web 83 has a downward projection 102 which is raised when it is moved along the section 103. By lifting the holder 81, the projection 82 is raised to a height position approximately in the middle of the opening 7 of the drawer. Since the drawer bottom 5 sits flush on the running rail 10, the optimal height of the projection 81 in the middle of the opening 7 is thus clearly determined, thereby simplifying the pushing of the drawer onto the projection 82.

FIGS. 17A and 17B show an assembly position in which the holder 81 has been moved backwards by the drawer 1, but not yet in the final position. As a result, the protrusion 102 projecting downward passes downward via the obliquely aligned section 103, so that the holder 81 is lowered into its normal position. This lowering of the holder 81 during assembly can be used to clamp the drawer 1. For this purpose, the lower web 83 or the holder 81 can be made in particular of spring steel. A clamping fixation of the drawer on the running rail 10 is also achieved in that when the drawer is pushed backwards, the lower web 83 with a control surface 129 meets a control cam 128 on the nose 90, and the drawer together with the lower web 83 further to the rear is pushed. The control surface 129 runs along the oblique control curve 128 backwards and downwards. As a result, the projection 82 pulls the drawer bottom against the upper edge of the nose 90. The lower web 83 can in this case be made of spring steel, this allows a tolerance compensation when clamping in height in connection with the pushing back of the drawer due to the elasticity.

Instead of lowering the holder 81, the holder 81 can also be raised, wherein, when lowering, slight clamping forces can be applied to the drawer 1 by the holder 81.

The adjustment mechanisms shown in the illustrated exemplary embodiments via elongated holes, pins, eccentrics can of course be modified by the person skilled in the art. Instead of an eccentric adjustment, a curve guide, a worm wheel or another component can be provided in order to carry out a corresponding adjustment. In addition, the linear guides can of course also be exchanged for slots and slides.

The mechanism for clamping the holder 81 on the rear wall 3 of the drawer can also be varied, the holder 81 is preferably moved obliquely downwards during assembly of the drawer 3 in order to fix the drawer 1 in a clamping manner on the running rail 10.
