ABSTRACT:
A device for extending and retracting a pool cover, for covering and uncovering a pool. A mechanism for coupling and uncoupling cover driving and driven sections includes a floppy clutch mechanism including a floppy clutch arm, pivotally mounted and operable so as to rotate, pivot, and drop into and out of engagement responsive to rotational and gravitational forces, so as to provide positive coupling and uncoupling for cover operation. The cover driving section includes a cable reel which includes a pair of adjacent sections, to each of which one end of a cable is connected, with the opposite end of such cable connected to the cover leading edge, for enabling efficient extension of the pool cover. A pair of tracks are mounted directly in the sides of the pool, through which tracks the sides of the pool cover extend, and a pair of sliders are directly connected and secured to the cover leading edge, to provide support and guidance for the cover during extension and retraction thereof.
