发明名称 Pool ladder
摘要 A pool ladder for use by individuals confined to a wheelchair having a top step which is at a height substantially equal to the height of a wheelchair seat, and a second step which is at a height slightly above the wheelchair foot rests. Both the top step and the second step are moveably connected to the ladder so as to allow them to be moved aside during standard use. A series of support members serve a dual purpose by supporting the steps of the ladder and also providing handgrips for one entering or exiting the pool.
