ABSTRACT:
The present invention is directed to a novel pulley assembly used in connection with conventional swimming pool cover systems of the type utilizing draw cords carried by a dual-channel track. The pulley assembly is comprised of a pulley housing and a pulley such that the pulley housing is adapted for securement at the end of a section of track. In a preferred embodiment, the housing is provided with a tang-like projection adapted to be received in a slot in the track between the two channels so as to maintain the pulley system in proper alignment with respect to the track and the pulley is rotatably secured within a cylindrical cavity having sufficient clearance to permit free rotation of the pulley, but the clearance being less than the diameter of the draw cord so that the draw cord will remain engaged with the pulley. The housing is also preferably provided with a pair of bores or grooves, one of which defines a path for the draw cord to the pulley, and the second of which defines a path from the pulley, so that the path of the draw cord is a substantially continuous U-shape.
