Abstract
A swimming pool rescue apparatus includes a safety pool bottom substrate, having a periphery made of a buoyant material and at least one non-peripheral portion is buoyant. The buoyant material is urged into a fixed position at a bottom of the pool by a retaining member. A lifting mechanism raises and lowers the safety pool bottom substrate. The lifting mechanism communicates with a detection signal device detecting the presence of a person under water in the pool for a predetermined period of time. The electronic signal device has a trigger engaging the lifting mechanism to release the buoyant material from a fixed position at the bottom of the pool to a further position at an upper area above the water level of the pool.
