Description

The The present invention relates to a device for stabilization the running behavior of a movable in a furniture body furniture part according to the preamble of the protection claim 1.

Especially with wide drawers and / or heavy duty drawers, it is advantageous to have a Side stabilization for to provide a drawer, the lateral tilting of the drawer prevented. Preferably, gears or friction rollers are over one Torsionswelle rotatably connected and mesh racks or run on a rolling surface. From the prior art are already numerous constructions known with an adjustable mounting of the torsion.

In the CH 445 761 discloses a parallel guide, wherein gears are coupled together by means of a torsion shaft, which are each engaged with a rack. The torsion shaft supports in drawer-mounted brackets, or feedthroughs may be provided on the side walls of the drawer, and the torsion shaft is mounted in a vertically slidable bearing. Disadvantage is that the rail system of the drawer is not or only very difficult to cover with a decor, since the rack or the gears are mounted on the carcass side rail.

In the EP 0 512 615 A1 is also known a parallel guide, wherein gears are connected by means of a torsion shaft. The height of the torsion shaft is adjustable by means of a screw. Disadvantage is that a height adjustment during the movement of the drawer during retraction / extension does not take place.

In the US 4,226,490 discloses a "drawer" for a dishwasher, wherein the torsion shaft is stored in a vertically displaceable bearing block .. Frictional rollers instead of gears were used for cost reasons.The disadvantage is that an exact synchronization of the two friction rollers left and right of the drawer is not guaranteed because a Positive fit as in the provision of gears missing.

In the AT 6674 U2 a stabilization system is provided, wherein the non-rotatably interconnected gears support in bearing bodies, which are displaced in the course of the drawer in height, the bearing bodies store in provided on the drawer brackets. For this purpose, a movable tooth is arranged at the end of each rack and the last fixed teeth of the rack are tapered. Disadvantage of this stabilization system is that the storage of the gears on the vertically displaceable bearing body on the holder of the drawer built relatively complicated and thus costly with a high manufacturing, assembly, maintenance and repair costs.

In the DE 91 03 551 U1 a drawer parallel guide is known, which is arranged above the drawer slide, wherein the movement space of the profile bar is below the drawer top edge, wherein the toothing (rack) is placed next to the pressure surface of the sprocket and is arranged deeper lying next to the ramp surface of the sprocket. The sprockets have a toothed shell portion and an axially outwardly spaced therefrom, not toothed, smooth outer surface with a smaller diameter. The rolling movement of the sprocket takes place on the lower horizontal leg of a U-profile and only on the smooth-edged smooth surface of the sprocket, which receives the vertical weight of the profile bar together with sprockets, while the toothed jacket portion of the sprocket itself serves only for synchronous movement of the drawer, without this toothed jacket area being subjected to vertical force of weight. Disadvantage of this drawer parallel guide is that no height adjustment of the drawer and / or the profile bar is provided in particular during the movement of the drawer. To deepen the U-profile is machined in the engagement area of the toothed portion of the sprocket with additional cost and thus weakened in stability.

disadvantage of these constructions is that a tilting of the drawer at exclusively on friction surfaces running friction rollers or meshing exclusively with racks gears can not be optimally prevented. In an improved leadership of gears the height-adjustable bearing bodies of the prior art is the production, assembly, maintenance and repair costs relatively high, while high vulnerability against wear or absolutely complete To fail. In a combination between running on friction surfaces Friction rollers and mesh with racks gears According to the prior art, is a height adjustment of the drawer and / or the profile bar in particular during the movement of the drawer at all is not provided, so that adjusting the drawer position not or only very limited possible is.

The object of the present invention is to improve a device of the type mentioned in that the hanging of the drawer is facilitated and that tilting of the drawer is avoided. Another task of the innovation is to allow a cleaner run of the drawer, even if the position of the drawer is changed (eg by inclination adjustment of the entire drawer). In addition, the ge velvet device can be produced inexpensively and have a low maintenance and repair costs.

The Task is solved by that on both sides of the mobile furniture part at least one each Gear is arranged over a rotatable connecting element are rigidly coupled together and wherein on both sides of the mobile furniture part continue at least each arranged a guide wheel is that over the rotatable connecting member mounted on this freely rotatable connected to each other, wherein the at least one gear and the at least one guide wheel with at least one body-fixed U-profile on both sides of the mobile furniture part interact so that the at least one gear with a rack or Zahneinprägungen on the upper horizontal legs of the U-profiles and combs the at least one guide wheel on the on the rolling surfaces the lower horizontal legs of the U-profile unrolls, wherein the rotatable connecting element in at least one bearing of a Holder on the mobile furniture part is mounted so that the mobile furniture part in relation to the rotatable Connecting element height-adjustable is.

Essential is so that at each end of the torsion a firmly connected Gear and an independent thereof rotatable and axially spaced from the gear guide roller are arranged over the horizontal legs of a U-profile run, the upper horizontal leg of the U-profile has a rack or a tooth impression, the combed from the gear and the lower horizontal leg of the U-profile is a rolling surface for the leadership role forms, with the torsion in at least one camp on the drawer is stored so that the drawer to the torsion wave height adjustable is.

The guide the role in the U-profile guaranteed while the positive connection of gear to rack.

The Rack serves as a limit to the top, the rolling surface as Limiter down to hold the torsion shaft.

A alternative embodiment The innovation involves the reversal of gear / rack and guide / rolling surface, so that the rack on the lower horizontal leg of the U-profile is arranged, with which meshes the gear and the rolling surface at the top horizontal leg of the U-profile is arranged, on which the guide wheel unrolls. The guide wheel can over it a spring load be pressed against the upper rolling surface. Prefers but is the initially mentioned solution with upper rack for the gear and lower rolling surface for the Guide wheel.

Advantageous stores the torsion shaft for height adjustment especially during the movement of the drawer in slot fasteners, attached to the drawer are fixed.

Of the The advantage is that the torsion shaft remains in the same position and that the drawer is moving up.

It can additionally or alternatively be provided that the rear end of the rolling surface of the U-profile milled deeper is to allow a dental balance when the left and the right side of the meshing between gear and rack itself around one or more teeth distinguish, so there is an offset.

Preferably are the back teeth of the Rack rejuvenates, so that the cutout may have a smaller depth.

Of the Subject of the present innovation does not arise only from the subject of the individual claims, but also from one any combination of individual protection claims with each other. Alone The information and characteristics disclosed in the documents, in particular those in the drawings shown spatial Training, are claimed as essential to the invention, as far as they individually or in any combination compared to the prior art new are.
