摘要： A reel system for winding swimming pool covers thereabout is constructed from a hub having an opening for receiving one end of a spool to be attached thereto. The hub includes a bushing and a wheel for rotating the hub about its longitudinal axis. A support stand having a bearing is arranged for rotationally supporting the hub about the bushing. Ultraviolet exposure and contamination by chemical and dirt is prevented in the area of the bushing and bearing by a cover arranged for engagement with the hub between a first and second position. The first position is such that the cover is at least coextensive with the bushing and bearing to prevent their exposure while the second position being remote from the bushing and bearing to allow disassembling of the reel system.
