Abstract
A closing device for a control cabinet door, machine casing or the like, having a security unit with a lock attached to the control cabinet door, machine casing or the like, with a first locking part and a second locking part fixed to the door frame, machine frame or the like. The two locking parts can be made to cooperate with each other or not by application of an electric signal. In a closing device there is a locking and unlocking mechanism suitable for use with all usual types of lock. Thus a lock is used which has a locking mechanism that can be rotated in different directions and in which a locking member subjected to a spring tension is movably guided. In addition, when in a locked position the locking member subjected to a spring tension prevents the rotation of the locking mechanism. A release member can be displaced by an electromagnet mounted on the door frame or machine frame and makes it possible to move the locking member in the lock into a locking position which permits rotation of the locking mechanism.
