INSTALLATION ARRANGEMENT FOR CONTROLLING HANDLE OPERATION IN A DOOR LOCK AND A DOOR LOCK PROVIDED WITH AN INSTALLATION ARRANGEMENT OF THIS KIND

摘要

An installation arrangement for a solenoid controlled handle operation in a door lock in which force transmission from an operation axis (3) for a handle or the like to a follower (4) acting on a bolt (12) of the lock is arranged by means of a movable coupling member (6,6'), which receives its guidance from a solenoid arrangement. The follower (4) is provided with two separate torsion units (13,14) which are installed on the operation axis (3) on different sides of the follower (4) and are turnably supported to it and which can be selectively coupled by means of said coupling member (6,6') to be in force transmission connection with the follower (4).
