ABSTRACT:
A portable apparatus for use in lowering and lifting a user into and out of a swimming pool includes a frame with vertical, longitudinally adjustable legs, horizontal support arms extending rearwardly from the upper ends of the legs, and feet extending forward from the lower ends of the legs. The support arms are adapted to rest on the pool deck and the feet are adapted to rest on the pool bottom, with the apparatus being held on position only by the frictional forces of the arms and the feet. The apparatus further includes a hydraulic cylinder moveable between raised and lowered positions, and a chair moved into the pool when the cylinder is moved toward its lowered position and lifted above the pool when the cylinder is in its raised position. The chair can be rotated at least 180° when in the raised position to permit user ingress and egress.
