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.
