Abstract: A motor-driving mechanism includes a motor and a lifting lever. The lifting lever is rotatable between a lifted position and a lowered position, and includes first section and a second section. The first section is pivotably connected to the motor. The second section is connected to the first section in such a way that the first section and the second section as a whole are drivable by the motor to rotate in a first direction from the lowered position toward the lifted position, and the first section is drivable by the motor to rotate relative to the second section in a second direction from the lowered position toward a third position while the second section remains at the lowered position, the second direction being opposite to the first direction. A motor-driven bed utilizing the motor-driving mechanism is also disclosed.

Abstract: The invention relates to an arrangement for isolating supply current from control devices, which satisfies higher safety standards while, however, being easy to operate. To this end, the inventive arrangement comprises a device for isolating supply current from control devices that are connected to a first voltage source, which is connected to power mains and which serves to provide an operating potential for a servomotor.

Abstract: On a lift bed comprising four, telescopic lifting columns, which can be connected by a reclining-surface frame (8), as well as by head (2), foot (3) and side elements (4), provision is made, to permit simple assembly and dismantling of the head, foot and side elements, for the lifting columns to each display a slit (5.4), which is parallel to the axis and points towards the adjacent side element (4), and for the reclining-surface frame (8) and the side elements (4) to display corresponding anchoring elements (4.3) that can be inserted into the slits (5.4) in sliding fashion from above.

Abstract: The invention concerns a linear drive (1) with a linear stroke for the displacement of movably supported parts, in particular of articles of furniture, comprising a rotary spindle (2) which is driven by a motor and which at the drive output side is in screwthreaded engagement with a thrust tube (3) or a spindle nut (4) connected thereto with a female screwthread (5), wherein the thrust tube (3) is mounted non-rotatably and slidably in the housing (6) and is displaceable in the housing (6) over a stroke travel h relative to the rotary element, and a travel measuring device for measuring the stroke travel h.

Abstract: On a foot-controlled operating element for motor-driven items of furniture, particularly lift beds (1) and treatment couches, with a motor-driven lifting mechanism and a foot switch for operating the drive, where the drive function can be activated by exerting a load on the foot switch, provision is made, for the purpose of deactivating the drive motor of the lifting mechanism, preferably reversing the lowering movement until the operator's foot is released, for the foot switch to display at least a second switching step, which can be triggered by increasing the operating force exerted by the foot beyond the normal load value, and stops the downward movement of the item of furniture.

Abstract: The invention relates to a safety device for furniture with at least one movable element which can be moved by a motor-driven positioning drive controlled by operating controls, particularly the head and/or foot of a base for a bed, or a seat and/or backrest element of an armchair, where the positioning of the element forms a gap in which an object or body part can become trapped as a result of the movement of the element. If a body part becomes trapped, this can lead to serious injury. Objects must also be prevented from becoming trapped, as they can cause damage to the furniture. According to the invention, at least one contact element is positioned in the gap which, when subjected to the pressure applied by an object or body part becoming trapped, closes an electric circuit which bridges a switch associated with one of the operating controls, the closing of which prevents further movement of the positioning drive.
