ABSTRACT:
In a collapsible bed structure for bed-ridden invalids, a bed section is provided on an upper open end of a bathtub, the bed section having at least first, second and third bed plates each pivotably connected at their neighboring side. A link structure is provided to change the bed section between a rest position in which the first, second and third bed plates are horizontally supported and an operative position in which the first, second and third bed plates are supported in a chair-shaped configuration within the bathtub. A pedestal plate is pivotably placed at one end by a hinge to the first plate of the bed section, the pedestal plate having a rack operative to move the pedestal plate upward around the hinge so as to raise the haunches of an occupant lying on the bed section to expedite the occupant's divestiture. A slide plate is slidably mounted on each of the first and second bed plates of the bed section to slightly slide along a lengthwise direction of the occupant so as to prevent a slippage between the occupant lying on the bed section and the first and second bed plates when changing the bed section from the rest position to the operative position.
