The lock plunger can also be activated via an electric motor (11), an output shaft (10), and a worm gear (9) which is in meshing engagement with a dogging element (8) which is pivotally mounted on the same shaft (7) as the follower element (17) and has dogs or projections (8b) which enter sector-shaped slots (17b) having a figure-eight configuration. When the electric motor is started the dogging element (8) is rotated through 90 DEG and the latch hook (4) adopts its locking position. The electric motor returns immediately the dogging element (8) to its starting position, while the follower element (17) remains.</p> |
