ABSTRACT:
An electromechanical door lock comprises a lock body (1), in which is a dead bolt (3) which can be dead locked in its protruding position and electrically withdrawn into the lock body, a latch (4) which is spring loaded to be protruding from the lock body and which centralizes the dead bolt in an opening in a striking plate (18) arranged for the door lock, and force transmission means (8-14) for transmitting force from an electrical operating device (7) to the dead bolt (3). Said latch (4) includes in a way known as such a body member (4c) moveable inside the lock body to which is jointed a wedge-shaped member (4a, 4b), protruding at least partly out from the lock body when the latch is in the protruding position, so that the latch (4) can be pressed inside the lock body when a force acts on said wedge-shaped member (4a, 4b) from either side of the lock body in the direction of the door opening or closing. In addition the lock body includes separate dead locking means (15-17) for the latch, arranged to prevent the latch to be moved inside the lock body. Said force transmission means (8-14) include a force transmission unit (11) moveable at least substantially in the longitudinal direction of the lock body, the transmission movement of which is arranged to release the dead locking of both the dead bolt (3) and the latch (4).
