Patent attributes
A power rotating transfer coupler is disclosed for use within a retractable shade system of the type operatively deployed upon a rotating roller member transversely disposed within a framework and mounted in connection with a boat, recreational vehicle or other stationary structure. Adapted for mounted attachment to the end of the roller member intermediate of the roller member and the adjacent framework, the power transfer coupler comprises a contact ring assembly set immediately adjacent to the roller member having separate continuous ring members of different diameter concentrically disposed each with a separate power wire attached thereto, a contact pin assembly having separate spring-loaded contact pins each connected to a lead wire and fitted within a cylindrical housing in a respective position to make contact with a respective one of the ring members, and a compression spring centrally positioned and set against of the end of the housing for constant tensioning of the housing against the contact ring assembly so that an uninterrupted electrical connection with the respective contact rings is maintained throughout relative motion of the roller member during operational deployment of the shade system.
