  • Patent number: 9605454
    Abstract: A rotary latch closure comprising a housing with an actuating shaft which is mounted so as to be rotatable, but axially fixed therein. The rotary latch closure has, at its free end, a circumferential thread, at least one axially oriented flattened portion, and a rotary latch configured to be fitted to the free end of the shaft so as to be fixed with respect to rotation relative to it in at least one rotational position and which is axially supported on a nut which can be screwed onto the circumferential thread. The nut is enclosed by a cage forming a laterally accessible space that is bounded by two walls, each of the two walls having a prismatic opening, wherein the opening allows the shaft to be slid through in a torsionally rigid manner.

  • Patent number: 8291732
    Abstract: A retractable hand lever actuator which can be locked in a trough for driving a latch for a switch cabinet or the like is described. The hand lever is articulated at a drive shaft supported in the trough. According to the invention, the hand lever actuator comprises a handle such as a T-handle or L-handle having two connection levers which are arranged relative to one another in a parallelogram configuration and which are articulated by one end at the drive shaft and by the other end in a similar manner at the handle in such a way that, on the one hand, they hold the handle in its direction parallel to the extension of the trough when the handle is folded out of the trough and, on the other hand, are able to transmit a rotational movement of the handle to the drive shaft in the folded out position.

  • Patent number: 5722269
    Abstract: A locking device is used for doors of cabinets or cupboards and, more parularly, for doors of modular cupboard systems. In order to create an operationally reliable, inexpensive locking device which is suitable for narrow counterstops and which permits an installation independently of the fixing side, as well as an inexpensive conversion when the fixing side is changed, the locking device is given a bipartite construction with a handle positioned in the vicinity of a door plate and a bolt mechanism operable by a tumbler. The device has a first door plate area receiving the handle and a second door plate area. A locking movement, initiated by the handle, is subject to a deflection, preferably of approximately 90.degree., in the direction of a counterstop and a closed or open position of at least one locking element in a cabinet or cupboard-side receptacle is obtained.
