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 forassisting in the deployment/take-up of a heterogeneoussystem including modules (8) intended to be placed orbeing placed in an environment, said modules (8) beingconnected by connecting means (7), said pulley beingintended to be mounted rotatably on an shaft placedabove said environment,characterised in that said pulley includes firstcooperating means intended to cooperate with saidconnecting means (7) and second cooperating meansintended to cooperate with said modules (8), said firstand second cooperating means being designed so as toproduce two successive operating states:- a first state, during which said pulley issubstantially stationary in rotation around said shaft(11) ;- a second state corresponding to the passage ofsaid modules (8), during which said pulley is driven inrotation around said shaft (11).
