Abstract
An ejection device for a movable furniture component disposed in or against a furniture body includes an electric motor, a lever having a free end for ejecting the movable furniture component, and a gear mechanism for transmitting force from the electric motor to the lever. The gear mechanism has a slipping clutch which includes a spring washer and driving dogs. The spring washer extends upon overload and slips over the driving dogs. The ejection device may also include a path measuring device which activates the ejection device. The path measuring device can be a potentiometer directly coupled to the lever such that slipping of the slipping clutch does not change a position of the potentiometer relative to the lever.
Claims16
An ejection device for a movable furniture component disposed in or against a furniture body, the ejection device comprising:
- an electric motor;
- a lever having a free end for ejecting the movable furniture component;
- a gear mechanism for transmitting force from the electric motor to the lever;
- and
- a first castor disposed at the free end of the lever, the first castor rolling along the movable furniture component as the lever is displaced and being configured such that the lever pushes but cannot pull the movable furniture component;
- wherein the gear mechanism has a slipping clutch which includes a spring washer and driving dogs,
- wherein the spring washer extends upon overload and slips over the driving dogs.
An item of furniture comprising:
- a movable furniture component to be disposed in or against a furniture body;
- and
- an ejection device for ejecting the movable furniture component, the ejection device including:
- an electric motor;
- a lever having a free end for ejecting the movable furniture component;
- a gear mechanism for transmitting force from the electric motor to the lever, the gear mechanism having a slipping clutch including a spring washer and driving dogs, the spring washer extending upon overload and slipping over the driving dogs;
- and
- a first castor disposed at the free end of the lever, the first castor releasably contacting the movable furniture component,
- wherein the movable furniture component has a range of motion which includes an end position in which the ejection device does not contact the movable furniture component.
