Above-ground swimming pool with integral automatic raising and lowering hard cover, and an automatic raising and lowering retrofit hard cover for an existing in-ground and above-ground swimming pool

Abstract

An above-ground swimming pool with integral automatic raising and lowering hard cover, and an automatic raising and lowering retrofit hard cover for an existing in-ground and above-ground swimming pool. The raising and lowering of the hard cover takes place with the utilization of two or more linear actuators that are telescopic or non-telescopic and actuated through the use of mechanical (screw jack, rack and pinion or pulley types), hydraulic (piston type), pneumatic (piston type), electro-mechanical, Piezoelectric and linear motor devices. The hard cover provides several benefits to the user of the pool.

1 . An above-ground swimming pool with integral automatic raising and lowering hard cover, comprising:
 A round, square, rectangular or oval shaped above-ground swimming pool with automatic vertically raising and lowering hard cover integrated into it.   Two or more linear actuators used to lift the hard cover from the lowered position to the raised position.   A controller that commands the power source to raise (extend) or lower (retract) the linear actuators.   A hard shell (not framework) made up of transparent material (polycarbonate, acrylic sheet) that does not have any UV filters in it, has UV filters in it, or has a photochromic coating applied to the outer surface.   A convex dome, multi-faceted pitched from center and flat pitched geometrical shaped hard cover.   A swimming pool vertical support with integral actuator base/housing.   A frame that is connected to the linear actuators and carries the load and provides attachment of the rigid transparent materials (polycarbonate, acrylic sheet).   
     
     
         2 . An automatic raising and lowering retrofit hard cover for an existing in-ground and above-ground swimming pool, comprising:
 A round, square, rectangular or oval shaped frame that conforms to the existing in-ground or above ground round, square, rectangular or oval shape.   Two or more linear actuators used to lift the hard cover from the lowered position to the raised position.   A controller that commands the power source to raise (extend) or lower (retract) the linear actuators.   A hard shell (not framework) made up of transparent material (polycarbonate, acrylic sheet) that does not have any UV filters in it, has UV filters in it, or has a photochromic coating applied to the outer surface.   A convex dome, multi-faceted pitched from center and flat pitched geometrical shaped hard cover.   A frame that is connected to the linear actuators and carries the load and provides attachment of the rigid transparent materials (polycarbonate, acrylic sheet).
