Title: Mechanical self-securing insert lock - has all movement programmed by control plate
Inventor: HAMME KURT
IPC: E05B59/00
Filed: 1990-08-04
Abstract: Locking automatically occurs when the door is closed, and in this position the bolt (4) and the catch (1) are simultaneously blocked, the bolt by a blocking component (6a), and the  catch by a lever arm (4a) rigidly connected to the bolt. The locking process takes place under the force effect of a draw spring (F3). The door is unlocked by means of the handle from the inside, with which it can also be locked. Each movement of the catch (1) - opening or closing the door - is taken over by the control plate (2) which moves a quarter of a rotation clockwise, and the bolt stop (3) is influenced by control bolts (2e, 2f) on the plate (2). Rotation of the control plate occurs by pressure from the arm (S1) of the catch on one of the four pins (2a, 2b, 2c, 2d) fitted underneath the plate.
