Description

Guide bearing and furniture element

The present invention relates to a guide bearing for guiding a body part that is mounted in a translationally and rotationally movable manner according to the preamble of claim 1.

The invention further relates to a furniture element according to the preamble of claim 15.

A furniture element, for example in the form of shelves or shelves, in which a body part is arranged on or in a support element in a rotationally and translationally movable manner, is known, for example, from JP H 10318669 A.

With such furniture elements there is often a requirement to protect the objects stored on them from dirt and to enable good accessibility to the objects.

Particularly with larger and/or taller body parts, for stability reasons it is necessary to adequately support the combined translation-rotation movement by a guide bearing, as is known, for example, from DE 10 2019 132 207 A1. A corresponding guide bearing can be arranged both above and/or below a corresponding body part.

The object of the present invention is to further develop a guide bearing and a furniture element in such a way that they can be operated without manual force.

This task is solved by a guide bearing with the features of claim 1 and by a furniture element with the features of claim 15.

The guide bearing according to the invention for guiding a body part which is mounted in a translationally and rotationally movable manner has a first plate with a curved guide track arranged on or in it on. A guide element arranged on a second plate is guided in the guide track.

The guide bearing further has a linear guide with connecting parts that can be displaced relative to one another, one of which is arranged on one of the plates and the other is mounted on the other of the plates by means of a rotary bearing.

The first plate or the second plate can be attached to the body part or is designed as a base plate or cover plate of the body part.

A drive track is arranged along the guide track, on which a drive wheel arranged on the second plate and drivable by a drive unit engages.

Alternatively, the guide element is designed as a drive wheel that can be driven by a drive unit.

With a guide bearing designed in this way, a guided translational-rotational movement of the body part is made possible in a simple manner by actuating the drive unit.

Advantageous embodiment variants of the invention are the subject of the subclaims.

According to an advantageous embodiment variant, the drive track is integrated on or in the guide track. This also makes it possible to use the guideway as a driveway.

According to an alternative embodiment variant, the drive track is designed as a track body that is separate from the guide track.

According to an advantageous embodiment variant, the drive wheel is designed as a friction wheel and the drive track is designed as a friction track.

This means that a side surface of the guide track can be used as a drive track in a particularly simple manner. According to an alternative embodiment variant, the drive wheel is designed as a gear wheel and the drive track is designed as a gear track.

Such an embodiment variant can be used in particular for body parts with a large mass, since the torque that can be transmitted by a drive wheel designed as a gear is higher than a friction wheel.

According to a further preferred embodiment variant, the drive wheel is biased in the direction of the drive track. A spring element is preferably used for pretensioning.

According to a further advantageous embodiment variant, guide rails designed as first connecting parts of the linear guide and the guide element are fixed to a carrier plate of the guide bearing.

The attachment of these components to a carrier plate enables a carrier element to be easily equipped with the components of the guide bearing to be attached to it.

According to a further advantageous embodiment variant, the drive unit has an actuating element for deactivating the drive unit when the body part reaches a predetermined position.

The actuating element for deactivating the drive unit can preferably be activated with a stop provided on the guide track or the drive track.

This ensures in a simple manner that the drive unit is deactivated in a timely manner or when a predetermined position is reached.

According to an advantageous development, the adjusting element is designed as an adjusting lever.

According to an alternative embodiment, the actuating element is designed as a contactless switching element.

According to a further advantageous embodiment variant, the drive unit has a control part for controlling a motor of the drive unit. With such a control part, a variety of operating options for the drive unit are possible.

The motor of the drive unit is preferably designed as an electric motor.

According to a preferred development, the control part preferably has actuation controllers, buttons or the like. Furthermore, the control part can be designed with a wireless interface to enable remote control of the guide bearing.

The control can be integrated into a common smart home system, preferably wirelessly via one of the common frequencies and radio standards (Bluetooth, Zigbee, WLAN, etc.). Voice or gesture control is also conceivable. It is also conceivable to control the storage via pre-programmed scenarios, for example depending on the time.
