Device enabling a closure system to clear an obstacle during its operation

摘要

One of the ends of an arm (1) is placed and attached to a given point (4) of the closure system (2). The other end bears on a fixed point (3). During operation, the arm (1) pushes the closure system (2) simultaneously upwards. The method comprises a device (7) on the pole (5) which, during rotation, enables the system (2) to be guided in translation. <IMAGE>
