Abstract
A solenoid arrangement for controlling handle operation in a door lock, in which force transmission from an operation axis of a handle or the like to a follower acting on a bolt of the lock is arranged by means of a movable coupling member which receives its guidance from the solenoid arrangement. The arrangement includes a shaft element which is arranged to move through a solenoid against the force of a spring and which moves a turnable lever member selecting the operating position of said coupling member. The position of the turning axis of the said lever member with regard to the coupling member is arranged to be selectively changed to provide a desired handle operation.

A solenoid arrangement for controlling handle operation in a door lock, in which force transmission from an operation axis (3) of 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) which receives its guidance from the solenoid arrangement, characterised in that it includes a shaft element (9) which is arranged to move through a solenoid (7) against the force of a spring (8) and which moves a turnable lever member (10) selecting the operating position of said coupling member (6), and in that the position of the turning axis of the said lever member (10) with regard to the coupling member (6) is arranged to be selectively changed to provide a desired handle operation.
A solenoid arrangement according to any one of the preceding claims, characterised in that it includes a selecting member (11) installed outside the lock case (1) of the door lock, comprising a stub shaft (11a) which can be inserted inside the lock case (1) so that it is in cooperation with the lever member (10) and serves as its turning axis in each case.
A solenoid arrangement according to any one of the preceding claims, characterised in that the end of the lever member (10) close to the coupling member (6) is provided with a magnet (14) for attracting the coupling member (6).
