Embodiment Construction

[0023] At the outset, it should be pointed out that with the furniture drive according to the invention both opening and closing of movable furniture parts (eg furniture flaps, drawers) is possible. This is achieved in the exemplary embodiment shown by means of a reversible electric motor. Figure 1a One embodiment of the furniture body 1 of the present invention is shown. The drawers are here moved in and out by means of the furniture drive 2 according to the invention. Figure 1b An enlarged detail view of a section marked with A is shown, in which the furniture drive 2 according to the invention can be seen.

[0024] figure 2 A view of an embodiment of a furniture drive 2 according to the invention is shown. Here, a roller 5 is driven by an electric motor 3 via a drive shaft (not shown) on which a gear wheel 4 is mounted, the roller 5 has a surface on which a force transmission element is wound or laid, which in this embodiment via A traction cable 26 is provided with a...

Abstract

The invention relates to a furniture drive (2) with a drive unit which comprises an electric motor (3) and a roller (5) that is rotatable about an axis, the roller (5) having a surface for attaching or winding up a flexible force transmission means (26). According to the invention, the radial distance of the surface changes in the rotational direction of the roller (5) for forming at least one control cam (6, 7) for the force transmission means (26).

Description

technical field [0001] The invention relates to a furniture drive having a drive unit with an electric motor and a roller rotatable about an axis, wherein the roller has a surface for laying or winding a flexible force transmission element. Background technique [0002] Furniture drives with electric motors already belong to the prior art. For example WO 2007 / 147180 shows a pull-in device for a drawer, wherein a motor rotates a roller via a drive unit and a traction element is then wound onto the roller, whereby the pull-in in the closing direction is connected to the puller drawers. A disadvantage of this type of furniture drive is that the motors used are only able to provide full torque from a certain rotational speed. This leads to problems when starting and braking furniture parts, such as drawers, with this type of furniture drive. Contents of the invention [0003] The object of the present invention is to provide a furniture drive which has simple means for faci...
