ABSTRACT:
A special bathtub for invalids has a fixed end part which abuts an oblong rotatable end part operable by control of the pressure of the water source. The center of curvature of the abutting faces of the fixed end part and the oblong rotatable end part is offset from the pivotal axis of the rotatable end part to incorporate a wedging feature in effecting a watertight seal. An interlocking latch and water sensor prevent inadvertent opening of the tub when it is filled with water.
