Description

Device for adjusting the inclination of a front panel

The present invention relates to a device for tilt adjustment of a front panel of a movable over two pullout guides on a furniture body of a piece of furniture between an open and a closed position furniture part, in particular a drawer, according to the preamble of claim 1. The invention further relates to a drawer and a piece of furniture. Various devices for adjusting the inclination of a front panel of a drawer are known from the prior art. The inclination adjustment of the front panel is carried out, for example, by a tilt adjustment of the side frames of the drawer relative to the mounted on the drawer rails of attached to the sides of the drawer drawer slides. In this case, an adjusting element in a on the

Length of the side frame extending adapter installed with the adapter and thus the side frame relative to the running rail at a side remote from the front panel end is raised or lowered and thereby a tilt adjustment of the front panel is achieved. Such Neigungsverstellungs- devices are expensive and heavy, especially by a relatively large amount of material.

It is therefore an object of the present invention to provide a device for adjusting the inclination of a front panel of a two furniture guides on a furniture body of a piece of furniture between an open and a closed position movable furniture part, in particular a drawer, which is less expensive to produce.

This object is achieved with a device for tilt adjustment with the features of claim 1.

According to the invention, in each of the side frames of the movable furniture part at least two A-adapter connecting the respective side frame with the running rail is provided, wherein on a front panel near front adapter, a first support for supporting the side frame is integrally formed on the running rail and the lifting and lowering device in one of the front panel distant rear A- Dapter is arranged and over the lifting and lowering device relative to the running rail can be raised or lowered. By providing several adapters, the adapter material can be used so that it is installed only at the necessary positions and thus saves material, mass and cost.

According to one embodiment of the invention, the lifting and lowering device has a coupling part attached to the rear adapter, on which a horizontally displaceable rack with a groove extending obliquely to the longitudinal axis of the rack and a slot extending parallel to the longitudinal axis is arranged horizontally displaceable, and a lifting and lowering part which is fixed in the assembled state at one end with a nose on the running rail and is supported with a bearing surface on the running rail and protrude to the two bolts perpendicular to the normal of the support surface and the longitudinal axis of the running rail. In this case, the first pin protrudes in the mounted state in the slot of the rack and the second pin in the mounted state in the obliquely to the longitudinal axis of the rack extending groove of the rack, so that by horizontal displacement of the rack on the second projecting into the oblique groove bolts Tooth days and thus the coupling part, the adapter and the side frame at an angle about an axis of rotation perpendicular to the normal of the support surface and the longitudinal axis of the track is pivoted. This ensures that a displacement of the front panel in the direction of the longitudinal axis of the side frame is minimized in the tilt adjustment of the front panel. According to a further embodiment of the invention, the lifting and lowering device mounted on the rear adapter eccentric, and a lifting and lowering part, which is fixed in the mounted state at one end with a nose on the running rail and with a bearing surface on the Supporting rail and on which a bolt perpendicular to the normal of the support surface and to the longitudinal axis of the track protrudes, which projects in the mounted state in a spiral groove of the eccentric, so that by rotating the eccentric the lifting and lowering part and thus the adapter and the side frame is pivoted at an angle about an axis of rotation perpendicular to the normal of the support surface and to the longitudinal axis of the track rail. Also with this embodiment, the displacement of the front panel in the direction of the longitudinal axis of the side frame is minimized. The tilt adjustment of the front panel is thus done by tilting the entire drawer. Thus, the drawer complete with front panel can be built as a unit. The entire inclination adjustment device is located between the drawer guides and the drawer in adapters that carry the side frames and thus the drawer. A drawer construction with side frames supported by adapters is also referred to as a system drawer. In these system drawers, it is advantageous if possible all functional elements are integrated into the frame adapter to allow a platform for the most flexible externa ßere design of the drawer. The drawer is then comparable to the body of a vehicle. The adapters, preferably with pullout guides, correspond to the chassis of the vehicle.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the example representation and position of the device and other parts selected in the respective figures. These terms are not meant to be limiting, that is to say, these relationships may change as a result of different working positions or the mirror-symmetrical design or the like.

1 shows a furniture 1 with a furniture body 2 and three arranged in the furniture body 2 and between an open and a closed position on movable furniture parts 3, which, as shown in Figure 2, for example, are designed as drawers 3, with front panels. 4 , 4 ', 4 "The number of front panels 4, 4', 4" shown here is to be understood purely as an example. In the furniture 1, at least one movable furniture part 3 is provided. The front panels 4, 4 ', 4 "are aligned as parallel as possible to the front edges of the front side of the furniture body 2.

Trained in Figure 2 as a drawer movable furniture part 3 has in addition to a bottom plate and a rear wall 6 on two side frames 5, which are fixed in a respective pull-out guide 7, with which see the movable furniture part 3 between an open and a closed position in the furniture body 2 is slidably guided along the side frames 5. The pullout guides 7 consist of at least one attached to the furniture body 2 guide rail 14 and a movable in the guide rail 14 and arranged on a side frame 5 of the movable furniture part 3 running rail 1 2 and optionally between the guide rail 14 and rail 1 2 arranged middle rail 1 third

As can be seen in Figures 3 to 6, in each of the side frames at least two the respective side frame 5 with the running rail 1 2 connecting A- adapter 8, 9 are provided, wherein on one of the front panel 4, 4 ', 4 "near the front Adapter 8 is a first support 1 5 for supporting the side frame 5 is integrally formed on the running rail 1 2. The first support 1 5 forms the pivot axis S for the drawer 3 and thus for the front panel 4, 4 ', 4 ". At the front panel 4, 4 ', 4 "far rear adapter 9 is a lifting and lowering device 20 is arranged, with which the adapter and thus the side frame 5 relative to the running rail 1 2 can be raised or lowered. The lifting and lowering device 20 shown in Figures 4 and 6 is shown in detail in Figures 7 to 1 1. The lifting and lowering device 20 shown in these figures has a coupling part 1 7 fastened to the rear adapter 9, on which a horizontally displaceable rack 23 with a groove 27 running obliquely to the longitudinal axis of the rack and a slot 26 running parallel to the longitudinal axis is arranged.

Furthermore, the lifting and lowering device 20 has a lifting and lowering part 28 which is fixed in the mounted state at one end with a nose 31 on the rail 1 2. For this purpose, a bracket 33 is preferably integrally formed on the upper side of the running rail 1 2, through which the tip of the nose 31 can be inserted. Below the nose 31, a third support 32 is integrally formed on the lifting and lowering part 28, which rests on the running rail 1 2. From a side surface of the lifting and lowering part 28 are two bolts 29, 30 perpendicular to the normal of the support surface and the longitudinal axis of the running rail 1 2 out. The first pin 29 protrudes in the assembled state in the slot 26 of the rack 23 and the second pin 30 protrudes in the mounted state in the obliquely to the longitudinal axis of the rack 23 extending groove 27 of the rack 23 inside.

If now the rack 23 is displaced in the horizontal direction, this causes simultaneously by the guidance of the rack 23 via the bolts 29, 30 of the lifting and lowering part 28, a pivoting of the rack 23 from the horizontal out. The rack 23 is longitudinally displaceable attached to the coupling part 1 7, so that the coupling part 1 7 is pivoted together with the rack 23 in the horizontal displacement of the rack 23 with. This is accompanied by an increase of the rear adapter 9 and thus the side frame 5 at an angle about an axis of rotation perpendicular to the normal of the support surface and the longitudinal axis of the track rail 1 second

The horizontal displacement of the rack 23 can be accomplished in a simple manner by an actuating opening 1 9 in the coupling part 17, which allows access to the toothing 25 of the rack 23. In order to be able to reach this actuating opening 19 from outside the side frame 5, an actuating element is also provided in the side frame 5, as can be seen in FIGS. 2 and 3. 1 1 provided, which overlaps with the actuating opening 1 9 of the coupling part 1 7 in the assembled state of the coupling part.

At the end remote from the oblique groove 27 of the rack 23, an obliquely to the longitudinal axis of the rack 23 extending pressure surface 24 is formed, which projects a tongue 22, which on the front panel 4, 4 ', 4 "facing the end of the coupling member 17, depending after horizontal positioning of the toothed rack 23 more or less presses in the direction of the running rail 1 2. The end of the tongue 22 thereby forms a further support 21 for supporting the coupling part 1 7 on the running rail 1 2.

Figures 1 2 to 14 show again the arrangement of the lifting and lowering device 20 and the front adapter 8 with the support 1 5 in different assembly states. FIG. 11 shows the adjustment range a of the second support 21.

In an alternative embodiment variant, the lifting and lowering device 35 is designed such that it has an eccentric wheel 47 fastened to the rear adapter 9, as well as a lifting and lowering part 37, which in the mounted state at one end with a nose 39 on the Running rail 12 is fixed. For this purpose, the nose 39 preferably protrudes into a bracket 40, which protrudes from an upper side of the running rail 1 2. The lifting and lowering part 37 is supported by a support surface 41, which is provided behind the nose 39 on the lifting and lowering part 37 from. A bolt 38 which protrudes perpendicular to the normal of the bearing surface 41 and the longitudinal axis of the track rail 1 2 from the lifting and lowering part 37, projects in the mounted state in a helical groove 36 of the eccentric 47, so that by turning the eccentric wheel 47 of the lifting and lowering part 37 of the adapter 44 and the side frame 5 is pivotable at an angle about an axis of rotation perpendicular to the normal of the supporting surface 41 and to the longitudinal axis of the running rail 12.

In this embodiment variant, the adapters 44, 45, 46 are preferably fixed in the side frame 5, an alternative variant of a lifting and lowering device 35 being arranged on the rear adapter 44 remote from the front panel 4. The lifting and lowering device 35 is preferably provided with a projecting in the direction of the front panel 4 extension piece 48 with a further support surface 43 for further support of the lowering device 35 on the track rail 12.

On the front adapter 46, a further bearing surface 42 is formed, which in this embodiment also forms the pivot point or the pivot axis S of the opposite side of the running rail 12 side frame 5.
