Door lock

摘要

The subject of the invention is a door lock, having a key-actuable bolt (2) which can move into a closing and an opening position. The bolt (2) is connected to a motor (29) via a non-positive connection which can be cancelled as a result of the rotation of a suitable key inserted into the door lock (1). If the energy supply fails, the motor (29), at least on the respective door, is fed from an energy accumulator (30). The motor (29) thereby moves the bolt (2) into an end position. <IMAGE>
