A quick-release mechanism for doors etc., primarily for emergency opening, adapted to actuate a lock on the door. The mechanism comprises two spring-loaded force-transmitting means (3, 4), of which the first means (3) is connected with the lock (2) and cooperates with a first spring (5) striving to open the lock. The second force-transmitting means (4) strives, under the action of a second spring (6), to open the door, both force-transmitting means being connected with a blocking device (7) which, upon actuation, releases said first means (3) and opens the lock (2), at the same time as also said second means (4) is released to open the door (1). |
