Abstract: The description relates to a closure for mounting in an opening in a thin wall, such as a sheet metal cabinet door, which comprises a housing and which has, at one end, a bearing support for an actuation lever and, at its other end, a lock device for the actuation lever and a fastening device such as a clamping clip therebetween. The housing has a partially spherical bearing surface with a cylindrical bore hole proceeding from it, wherein a partial ball with a first bearing for a closure drive shaft extending through the cylindrical bore hole and with a second bearing for the actuation lever is arranged in the cylindrical bore hole, and the two bearings enable a rotation of the partial ball in relation to the housing and a swiveling of the actuation lever in relation to the partial ball around an axis vertical to the closure drive shaft and to the extension of the lever.

Abstract: An electronic lock system comprises a recessed grip which can be mounted on a door leaf or the like, in which a lockable grip lever is held by one end around an axis parallel to the door leaf by the recessed grip or by a drive shaft for a bar lock, sash lock or the like which is held therein, and further comprises a locking device by which the grip lever can be locked into its position in which its is swiveled into the recessed grip. According to the invention, the locking device is constructed in a modular manner and comprises the following exchangeable components (modules): a base module with a movable bolt which, in its locking position, secures the grip lever in its swiveled in position, and with a device for supplying electric energy (e.g., a battery) for driving the movable bolt, which base module can be inserted through an opening formed by the recessed grip and can be secured therein.

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.
