Abstract

The invention relates to a device (3) for simultaneously interlocking a plurality of actuators (1) by means of a first locking element (5) which is assigned to each final control element (2) of an actuator (1) and which interacts with a second locking element (6). The second locking element is fixed inside the housing (4) in an actuating direction of the final control element (2) and is displaced into an interlocking position by spring force and into an unlocking position by an assisting force. The invention provides that a plurality of second locking elements (6) are interconnected and are actuated by a common device (11). As a result, the variety of parts, the safety risk, the weight, and the constructional complexity are reduced which is very important especially when the inventive device is used in helicopter.
