PULLEY FOR ASSISTING IN THE TAKE-UP/DEPLOYMENT OF A HETEREOGENEOUS SYSTEM BEHAVING DIFFERENTLY ACCORDING TO TWO SUCCESSIVE STATES, AND CORRESPONDING DEVICE

摘要

The object of the invention is a pulley for assisting in the deployment/take-up of a heterogeneous system including modules (8) intended to be placed or being placed in an environment, said modules (8) being connected by connecting means (7), said pulley being intended to be mounted rotatably on an shaft placed above said environment, characterised in that said pulley includes first cooperating means intended to cooperate with said connecting means (7) and second cooperating means intended to cooperate with said modules (8), said first and second cooperating means being designed so as to produce two successive operating states: - a first state, during which said pulley is substantially stationary in rotation around said shaft (11) ; - a second state corresponding to the passage of said modules (8), during which said pulley is driven in rotation around said shaft (11).
