| Abstract: |
A chair base structure on casters has four tubular legs with which telescope the uprights of a vertically movable seat structure actuated by the piston and cylinder of a hydraulic lift jack. Pivoted at one end to the seat structure is a tiltable slide support upon which an invalid transfer slide is reciprocably mounted. The rearward uprights of the seat structure are provided with laterally swinging chair arms which enter sockets on the forward uprights and are pivoted to chair-pushing handle bars. A plastic bearing plate placed on the bed assists the operation of the slide in transferring an invalid between the bed and the chair. The slide support is provided with a central opening which enables its use as an auxiliary toilet seat when moved over a toilet bowl.
