ABSTRACT:
A three-dimensional lift intended for use by a handicapped person, providing him with three dimensions of mobility within a room or rooms. The invention consists of uniform channels or rails secured in parallel configuration adjacent to or on a room ceiling with a traveling bridge arranged to traverse the length of the channels, and incorporates with the bridge a head mounted to travel thereacross spanning the room or rooms with a sling suspended therefrom to move vertically, supporting the handicapped person, and includes a remote control hung from the head, accessable to and giving the handicapped person the capability to operate the device while he is seated in the sling, providing that person with three dimensions of travel that they control. The invention includes two motors that are arranged with the head turning sprockets in fixed chains connecting between the wall channels across the traveling bridge to provide movement of the traveling bridge and head thereacross, with a third motor providing vertical movement of the sling. The motors are preferably operated by a low voltage system, preferably through batteries, to limit a potential for dangerous electrical shock to the handicapped person should the control contact water.
