ABSTRACT:
A swimming pool cover and roll-up device combination comprising a flexible shaft extending intermediate of the swimming pool cover from one edge to an opposite edge, with the flexible shaft being connected at least intermittently along its length to the swimming pool cover. A crank arm or other wind-up device is provided to be connected at least to one end of the flexible shaft for applying torque to the flexible shaft. The flexible shaft can transmit the torque through the length thereof to roll up the swimming pool cover on the flexible shaft. The flexible shaft and swimming pool cover are adapted to float on the surface of the water, and when it is necessary to store the rolled-up swimming pool cover, it is removed completely from the swimming pool and stored remote therefrom.
