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.
