ABSTRACT:
An assembly for covering a swimming pool when it is not in use. A roll member is rotatably mounted at one end of the pool for rolling up and unrolling a sheet of material of dimensions for covering the pool. A scissor type extension device moves the outer end of the sheet toward the other side of the pool when unwinding. The scissor device is moved between the retracted and extended positions by a rotating screw. An electrical motor rotates the screw and the roll member. A slide track mechanism submerges the entire assembly when rolled up.
