<p>The device consists of a linear actuator (A) and a lock (B). The linear actuator (A) is connected with a stationary (3) and a mobile (5) articulated joint between a stationary frame (1) and a mobile frame (2) in the plane perpendicular to the axis of inclination of the mobile frame (2) The lock (B) comprises a stationary member (7) and a mobile member (13) secured respectively to both frames (1, 2) and interlocked in the closed position by a bolt (6) controlled mechanically by the linear actuator movement at the final section of its stroke. The bolt (6) of the lock (B) constitutes a pin of the mobile joint (5) moved by the linear actuator (A) in the guide (14) made in the mobile member (13). The mobile member has a spring (14) loaded pawl (15) holding the bolt (6) in the extreme outer point (b) of the guide (14), having also a releasing mandrel (19), which cooperates with the bumper (12) of the stationary member (7) by lifting the pawl (15) and releasing the bolt (6) during the holding down and locking phase of the mobile frame (2) and during mounting the bolt (6) in the socket (11) of the stationary member (7) in the extreme inner point (a) of the guide (14).</p> |
