The final wheel in the central gearing (7) comprises two separate gear-wheels and the one intermeshing with the corresponding gearing wheel is a free-wheel (15) containing a curved slot (17) with a given length. The gear-wheel intermeshing with the push bar connection slides (8) is an output wheel (16) with a follower cam (18) extending into the slot in the free-wheel. The length of the slot is chosen so that the free-wheel only has to be rotated through less than 360 deg. by the motor gearing (10) when the central gearing is still, in order to completely lock or unlock the central lock (1) and satellite bolt (3). The locking device comprises a key-operated central lock, a drive motor and a push bar operated by this lock and motor in order to operate a satellite bolt. The central lock has a lock cylinder connected to the push bar via a central gearing and push bar connection slides. The final wheel in the central gearing has two gear rims, one for intermeshing with the push bar connection slides and the other for intermeshing with a gear- wheel in the central gearing. |
