Method and apparatus of extending and retracting swimming pool covers

摘要

An apparatus for extending and retracting a swimming pool cover includes a motor, a drive shaft connected to the motor, a cover collecting drum attached to the drive shaft and a cable collecting reel mounted on the drive shaft. A series of gears are configured to selectively engage the drive shaft with either the cable collecting reel or the cover collecting drum. A cable secured at one of its ends to the cable collecting reel and at its opposing end to the leading edge of a cover mounted on the cover collecting drum is operative to extend the cover over a swimming pool. The cover collecting drum functions to retract the cover from off of the swimming pool.
