ABSTRACT:
A swimming pool cover for an indoor pool which is designed to cover an in-ground pool that is positioned below floor level in a manner so that it provides a support floor when in place that is merely a continuation of the existing floor and which can be raised up vertically when the pool is to be used and become a false ceiling. The cover is provided with vertical guides that prevent it from twisting or coming out of proper orientation, and the guides have safety ratchets that prevent the pool cover from accidentally lowering. The hoist mechanism is stored out of sight in a crawl space or attic above the normal ceiling and operates through cables and pulleys for positively moving the pool cover between its raised and lowered position so that the pool, when covered, provides floor space for a recreation room or party room and also tends to seal the water surface to prevent excessive moisture from escaping into the room.
