<p>In a lock fitted with a rotary latch ( 30 ), a detent ( 40 ) is provided that can engage inside a preliminary catch and inside a main catch ( 32 ) of the rotary latch ( 30 ). The rotary latch ( 30 ) receives a locking part and can be transferred either manually or by means of a motor between an open position, a preliminary catch position and a main catch position ( 30.2 ). The motor-driven displacement ensues via a closing aid or an opening aid. In order to obtain a space-saving design, the invention provides that a locking lever ( 10 ) is eccentrically mounted on the rotary latch ( 30 ) and is held in a central position by an impulse spring whereby functioning as a closing aid. A stationary, rotationally mounted driving element ( 50 ) serves an opening aid, and an opening lever ( 20 ) is rotationally mounted on this driving element. This opening lever ( 20 ) is also held in a central position by an impulse spring. The locking lever ( 10 ) projects inside the preliminary catch position always in the path of rotation of the eccentric ( 21 ) and is entrained in one direction when the motor turns. In an analogous manner, the opening lever ( 20 ) projects into the main catch position ( 30.2 ) in the path of rotation of the eccentric ( 21 ) and is entrained in the opposite direction during rotation ( 23 ). The entrained opening lever ( 20 ) pushes, via the driver ( 50 ), the detent ( 40 ) from the rotary latch ( 30 ), whereby the door is opened by a motor.</p> |
