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

摘要

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.
