  • Patent number: 4446586
    Abstract: An arrangement for bathing invalids, or others with impaired ambulatory ability, comprises an enclosure having a bathtub with upstanding walls which form a stall. The bathtub includes a seat having an anatomical contour and a lateral opening adjacent the seat to permit invalid ingress and egress. A door with a generally wedge-shaped contour mates with and selectively closes the bathtub opening, and includes a seal compressed between the opening lip and the door to form a seal which is sufficiently leakproof to permit immersal bathing of a seated invalid. The door is slideably mounted on a hingeless track assembly, which vertically translates the door into the closed position and pivots the door as it is raised into a horizontal, overhead storage position. Shower heads are mounted on the walls of the stall to provide both shower and immersal bathing for hygiene and therapy.

  • Patent number: 4365367
    Abstract: A bathing apparatus for invalids and the like, comprises a bathtub having a lateral opening in one side thereof for invalid ingress and egress, a door selectively closing the bathtub opening, and a seal positioned between the door and the bathtub. The door is slidably mounted in a pair of tracks disposed on opposite sides of the door for vertically translating the door between open and closed positions. A counterbalance for the door comprises a pair of spools mounted on opposite ends of a spring loaded axle, and a pair of flexible lines having one pair of ends wrapped around the spools, and the opposite ends attached to the door, whereby downward translation of the door tenses the spring and counterbalances the weight of the door. A lock for the door comprises a foot operated lever arrangement, which engages both sides of the door and positively pulls the same downwardly against the seal into the closed position.
