Problems solved by technology

In the event of a malfunction, the motor, due to its internal obstruction, hinders manual operation, so that the movable furniture part cannot be used until it is repaired
In addition, the speed of the driven furniture part is defined by the speed of the electric drive, which is generally a disadvantage, since it is more desirable to operate the movable furniture part according to the working speed of the corresponding user

Embodiment Construction

[0023] figure 1 A perspective view of a piece of furniture 1 with a furniture part 3 in the form of a movable, movable drawer 4 is shown.

[0024] Due to the purely schematic view, the pull-out guides usually provided for the drawers and installed on the two opposite side walls of the furniture body 2 are not shown. In order to move the drawer 4 from the closed position into the open position and vice versa, a drive 7 with an electric drive unit 5 is provided, wherein the movement is transmitted to the drawer 4 via a transmission 6 . For reasons of advantageous force transmission, the transmission 6 is arranged centrally below the drawer bottom 4a. The drawer 4 is shown in the open position in the figures shown.

[0025] figure 2 show figure 1 A schematic perspective view of the drive device 7 shown in . The drive comprises an electric drive unit 5 which acts on a cable drive via a transmission 11 , preferably a bevel gear transmission, and a coupling 12 . The speed cha...

Abstract

The invention relates to an item (1) of furniture having a drive apparatus (7) for movable furniture parts (3) with a preferably electric drive unit (5) and a coupling apparatus (12) for at least temporarily transmitting the force of the electric drive unit (5) to the movable furniture part (3), wherein the coupling apparatus (12) has a drive (13) and an output drive (16), and wherein coupling elements (14a) act between the drive (13) and the output drive (16), can produce a clamping connection between the drive (13) and the output drive (16) and therefore coupling of the latter in a first operating position, and can be moved into a position in which the drive (13) and the output drive (16) are not coupled in a second operating position - preferably by spring means (14).

Description

technical field [0001] The invention relates to a piece of furniture with a drive for a movable furniture part, the drive having a preferably electric drive unit and a device for at least temporarily transmitting the force of the electric drive unit to the movable A coupling device on a moving furniture part, wherein the coupling device has a drive part and a driven part. Background technique [0002] The use of drives of the described type for movable furniture parts having an electric motor and a coupling has long been known from the prior art. Usually, the coupling is designed as an overload protection device, which disengages from the electric drive when a specified maximum torque is reached or exceeded. In the event of a fault, the motor blocks manual operation due to its internal blocking, so that the movable furniture part cannot be used until it is repaired. Furthermore, the speed of the driven furniture part is regulated by the speed of the electric drive, which i...
