Abstract: A telescopic column for a height-adjustable table comprises a cylindrical outer column, a cylindrical inner column at least partially arranged within the outer column, several balls, and a tube-shaped ball cage retaining the balls at positions relatively determined with respect to one another. The outer column comprises, along its longitudinal direction on its inside, an outer column running surface section configured such that the balls roll over thereon, the inner column comprises, along its longitudinal direction on its outer cross-section, an inner column running surface section configured such that the balls roll over thereon, and the inner column and the outer column are configured such that the balls, during an adjustment of a length of the telescopic column, roll over in an almost backlash-free manner on the outer column running surface section and the inner column running surface section in a predefined range of motion of the balls in order to guide the inner column in the outer column.

Abstract: A supporting device for a height adjustable table (1) comprises a first (3) and a second supporting element (3?) respectively having a first, a second, and a third liner component (5, 5?, 6, 6?, 7, 7?) arranged in a manner displaceable relative to each other to cause a change of length (L) of the supporting elements (3, 3?). The first (5, 5?), the second (6, 6?) and the third liner component (7, 7?) are coupled such that a displacement of the second to the first liner component synchronously causes a displacement of the third to the second liner component. The supporting device comprises a synchronization device to synchronize the displacement of the second liner component (6, 6?) to the first liner component (5, 5?) or the displacement of the third liner component (7, 7?) to the second liner component (6, 6?) between the first and the second supporting elements.

Abstract: A system (3) for fixing a furniture leg to a furniture comprises a fixing element (4) and a retaining element (5). The retaining element (5) comprises a first and a second protrusion on one side. The fixing element (4) comprises a first side (S1), a second side (S2) adjoining the first side (S1), and a third side (S3) opposite to the first side (S1), a recess (6) being open towards the first side (S1) and a pretension face (7) starting from the second side (S2) and running along the third side (S3) and a stop face (8) adjoining the pretension face (7) and protruding from the third side (S3). The retaining element (5) and the fixing element (4) are configured such that the system (3) enables fixation without backlash of the furniture leg to the furniture in a state in which the first protrusion is in contact with the recess (6) and the second protrusion is in contact with the pretension face (7) without backlash.

Abstract: A gas spring system (3) for a height adjustable table (1) comprises a gas spring (4) having a gas spring cylinder (6) with a gas compartment (9) provided therein, a gas spring piston (7) arranged therein and a gas spring piston rod (8) joined thereto. The gas spring system (3) further comprises a gas interface (10), connected to the gas compartment (9), which at least inserts gas from outside into the gas spring system (3), a transfer cylinder (12) having a transfer piston (13), a first transfer chamber (14) and a second transfer chamber (15) separated by the transfer piston (13), and a hydraulic pump (16). The gas comportment (9) is connected to the first transfer chamber (14) and the hydraulic pump (16) is connected to the second transfer chamber (15).

Abstract: A frame of a furniture is disclosed, comprising a bearing, which is provided for rotatably mounting of a foldable pillar about an axis, and a fixation which is provided for receiving and fixing the foldable pillar. The frame is designed in a way, that fixing can be realized by clamping of a fixation equipped with an eccentric. Moreover a securing element is disclosed, which can be brought in a securing position by a lever, whereby the lever thereby simultaneously causes the pillar to be clamped in the frame.

Abstract: A driving column (6), for instance of a piece of furniture (9), comprises a motor (1), a motor board (2), a motor supply cable (3) and a motor plug (4). In the driving column (6) an identification means (5) is integrated either into the motor board (2), the motor supply cable (3), or the motor plug (4), having data for identification of the respective driving column (6) stored therein. During the assembly, these data are assigned to the control unit (10) of the piece of furniture (9) to program it accordingly, such that a danger of confusion is reduced and the manufacturing process is simplified.

Abstract: This invention relates to a device and a method for recognizing collision of automatically moveable parts of furniture with obstacles by detecting a change in bend or a change in acceleration. This is carried out by a device for recognizing collisions of automatically moveable parts of furniture with obstacles, comprising a piece of furniture with at least one moveable part (1, 2, 31), wherein this part is a adapted to be moved relatively to the rest of the furniture in a non-manual manner, an automatic driving mechanism adapted to move the moveable part, a controller adapted to control the automatic driving mechanism, and a sensor (4) adapted to detect a collision with an obstacle during the movement of the moveable part and to transmit the collision to the controller, wherein the sensor is adapted to detect a change in bend or a change in acceleration of the moveable part.

Abstract: The furniture leg has a foot from which a lifting column projects transversely that comprises an external tube and an internal tube that is telescopingly movable relative to the external tube. The external tube is attached to a fastening part of the foot. In order to configure the furniture leg in such a way that the foot and the lifting column can be connected to one another such that deposit locations for dirt and the like are not formed, the exterior side of the external tube at least over most of its circumference passes continuously into the exterior side of the fastening part. In this way, at the transition from the foot to the lifting column no deposit location for dirt is formed. The furniture leg is suitable for tables of any kind, chairs, organ benches and the like.
