Abstract
Abstract A swimming pool lift installation for the handicapped employs a platform for carrying a wheelchair that is lowered and elevated with the platform so that a handicapped person can sit on his chair and be lowered into the pool for swimming away from the chair and can leave the pool by swimming back into the wheelchair. The chair is releasably secured to the platform so that there is no danger of it being rendered unstable by its buoyancy in the water and so that it can be wheeled on and off the platform. A water hydraulic system operates the lift to avoid contamination of the pool.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
196 words
Swimming pool apparatus for handicapped persons comprising: in combination with a swimming pool; a wheelchair lift platform; and means for mounting said lift platform at the edge of the swimming pool so that a wheelchair can be readily wheeled onto and off of said platform respectively from and back to the deck of said swimming pool; said lift platform including means for lowering said platform into the water of said pool with the seat of the wheelchair submerged and for elevating said platform out therefrom, wherein said platform includes a fixed stop for the wheels of said wheelchair, said wheel stop being positioned adjacent the outer end of said platform and transversely to the direction of wheeling onto said platform to prevent wheeling off said outer end; and means for releasably securing a wheelchair to said platform to retain the wheelchair thereon against buoyancy effects when lowering said wheelchair into said pool and raising said wheelchair therefrom, whereby a handicapped person can sit on a wheelchair secured to said platform while being submerged, can swim away from a submerged wheelchair, and can swim back to the submerged wheelchair to be elevated out of said swimming pool.
