Abstract
Abstract A device for transferring an invalid from a wheelchair into a bathtub and back from the bathtub into the wheelchair, consisting of a vertically pivoted frame adjacent the bathtub with a hoist assembly on the frame including a pair of parallel horizontally pivoted arms which can be attached by the invalid to a removable wheelchair seat portion. The hoist motor can be controlled by depending cables connected to forward and reverse motor switches. Other depending cables are provided for manually swinging the frame from a laterally projecting position relative to the bathtub to a position over the bathtub, and vice versa.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
In combination, a bathtub, a horizontally extending frame structure, means pivotally supporting said frame structure in an elevated position at a fixed height relative to the bathtub for horizontal rotation around a vertical axis located so that said frame structure may be swung from a position projecting laterally from the bathtub to a position overlying the bathtub, and vice versa, a hoist means on the frame structure, a body-supporting member connected to said hoist means, and means for rotating said frame structure in opposite directions comprising respective externally connected control cables extending over opposite side portions of the frame structure and depending from said frame structure adjacent said body supporting member, whereby a person occupying said body-supporting member may be elevated by said hoist means, may be swung over the bathtub, and may be then lowered into the bathtub by said hoist means.
Claim 2
Dependent Claim
