Abstract: The invention relates to a locking device for doors, compartments, and flaps. The stator is equipped with a battery-operated motor and an electronic control unit which acts on the motor. A handle (20) is connected to the rotor (30) so as to transmit a torque and is held on the rotor (30) by a clamping spring (50). The clamping spring (50) has a receiving area for a magnet (60). The process of replacing the battery for the motor is easily facilitated in that the clamping connection between the handle (20) and the rotor (30) is triggered by an external influence on the magnet (60) (FIG. 1).

Abstract: The present application relates to a lifting column for a piece of furniture, in particular for a table. The lifting column comprises a first element and also a second element. The second element is introduced at least some way into the first element. The first element has a spindle, which extends along the longitudinal axis of the first element and projects at least some way into the second element. The second element has a rotor, which is mounted in a rotatable manner in it and has at least one rolling body, which runs in or on a thread helix of the spindle. A rotation of the rotor relative to the spindle gives rise to a linear movement of the second element relative to the first element. The second element also has an arresting device, which, in a first state, blocks the rotation of the rotor relative to the spindle and, in a second state, frees the rotation of the rotor relative to the spindle.

Abstract: A device for opening or lifting a door (22) that hangs down by a hinge (23) with a horizontal swivel axis is characterized by an elbow lever mechanism, which is operated by means of a spring element (21) and which can additionally be folded down in the area of its dead point when the door (22) is still hanging or which is at its maximum force transfer when the door (22) is swivelled up. The door should preferably also be able to be folded down.

Abstract: A connecting device, in particular, for connecting two rod elements, has an expansion wedge construction that can be clamped in a tube-shaped end of the first rod element by expansion and that can be connected with the second rod element via a connecting piece. The expansion wedge construction includes an expansion mandrel and an expansion casing that can be engaged on the expansion mandrel. Expansion mandrel and expansion casing have an oval axial cross-section in such a manner that the wedge surfaces, which are formed in the area of the strong curvature between expansion casing and expansion mandrel, essentially are no smaller than the corresponding force locking surfaces that are made on an outside wall in the area of a strong curvature. Wedge-shaped wall thickenings of the casing are made in mirror-symmetry fashion on the inside of the surface area are molded-on in the mutually dialectically opposite areas with strong curvature.

Abstract: In the process proposed, tubular struts (3a to 3d) are detachably connected to a column (1) using a connection device, wedge element pairs (5a to 5d) on the connection device being inserted in the struts (3a to 3d) and the wedge elements (23, 24) of the wedge element pairs (5a to 5d) being displaced longitudinally with respect to each other by screws (13, 17a, 17c) which pass through holes (12a to 12d) in the column wall and through a throughbore (11a to 11d) in each wedge element pair (5a to 5d). The wedge elements (23, 24) of each wedge element pair (5a to 5d) are thus pressed against the inside walls of the struts (3a to 3d). The heads (27a to 27d) of the screws are located outside the column (1). The column (1) is reinforced by an internal core (7) and the shape of the end (39) of one (24) of the wedge elements in each pair matches that of the outside wall of the column (1).

Abstract: The fastening device (5) for the releasable fastening of a strut (3a-3d) to a column (1) comprises a retainer ring (7), attachable to the column (1), and a connecting element (9a-9d) for connecting the strut (3a-3d) to the retainer ring (7). The connecting element (9a-9d) has at one of its ends diametrically opposed jaws (33a, 33b) which extend around the lateral surfaces (16a) of the retainer ring (7) whereby the strut (3a-3d) is fastened to the column (1) safe from twisting even with respect to large torques and bending moments. The exact horizontal position of the strut or struts (3a-3d) can be adjusted by rotating the retainer ring (7).
