  • Patent number: 5056169
    Abstract: A bathtub having one panel which slides down, allows entrance for a handicapped person in a wheelchair or on a trolley without having to climb over the side. The bathtub permits a handicapped person to be independent and not rely on others. One fixed vertical side is joined to two end walls extending up from a bottom surface to form a bathtub, a sliding panel, representing at least a portion of the other vertical side of the bathtub, is mounted in tracks in the two end walls. The tracks extend down and curve under the bathtub allowing the sliding panel to be lowered to a lowered position to permit entry and exit. The sliding panel can be raised and lowered between the lowered and raised positions, and a seal is provided to seal the panel in the raised position.

  • Patent number: 4953241
    Abstract: An improved bathtub with a door for easy access by older and physically handicapped persons is disclosed. The bathtub includes an entrance wall with an opening which conforms to the shape of the door, and a front wall adjacent to the entrance wall. A seat is located in the tub with the forward edge of the seat located so as to provide a leg space between the seat and the front wall of the tub. The front edge of the door is attached adjacent to the front wall of the bathtub by means of a double axis hinge. When the door is opened, its front edge is guided directly inwardly in the tub by means of a tracking mechanism and the rear edge moves forward without any significant inward movement. In the fully opened position, the door is parallel to the front wall. The door is so configured that during movement it does not swing over the seat, and an occupant of the tub can be seated while the door is moved between its closed and open positions.

  • Patent number: 4542545
    Abstract: A generally rectangular open topped vessel with vertical walls around the periphery of a floor consisting of two integrally formed levels, the lower level being at one end providing a footwell and having a drain therein. Near the end of one side wall, in the area where the footwell is located, is a door opening. This door opening has a ferromagnetic faced door stop around the edge. A door is hingedly attached to the edge of the opening such that it swings horizontally inward towards the nearest adjacent end wall. The door has a flange along its two vertical edges and along its bottom horizontal edge. Mounted concentrically on the flange are two magnetic gaskets such that when the door is closed the gakets force a water tight seal with the ferromagnetic plate on the door stop. A second drain is located in the surface of the bottom door stop such that when the door is closed water in the vessel cannot reach the drain due to the sealing of the outer gasket.

  • 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.
