Definitions

  • ABSTRACT I This invention involves a bathtub having a door in one wall so [561 Cited hinged as to swing inwardly. A seal is maintained between the UNITED STATES PATENTS door and the opening in the tub wall, and this seal is reinforced by the water in the tub.
  • a drain stopper is provided which is Schmidt carried the door and cannot be put into drain 2,344,990 3/1944 Landauer .4/173 Stopping position unless the door is closed 2,569,825 10/1951 Otis ...4/173 2,611,135 9/1952 Greene ..4/185 10 Clairm,3l)rawing Figures Patented May 23*, 1972 FIG. 2
  • the present invention relates to a bathtub one of the walls of which has an opening therein equipped with a door.
  • the object of the present invention is to provide a bathtub of the mentioned type which can be used easily by aged, infirm or handicapped persons and the price of which is lower than that of known bathtubs of such type.
  • the bathtub of the present invention is characterized in that the door opens toward the interior of the tub.
  • FIG. 1 is a perspective view
  • FIG. 2 is a view in section taken along line lI-II of FIG. 1;
  • FIG. 3 is a view of a detail shown in section to an enlarged scale, and taken along line III-III of FIG. 2.
  • the general shape of the bathtub shown in the drawings is rectangular.
  • the inner sheet of metal forms a seat I, the height of which is about 40cm above the bottom of the tub.
  • the wall opposite to the seat defines a rectangular opening 2 which extends from the upper edge of the wall to a distance of several centimeters from the bottom of the tub.
  • This wall is provided with a door 3 in the form of a rectangular panel the width of which is slightly greater than that of the opening 2, the height being equally larger than that of the opening.
  • the door 3 is connected to the inner wall of the bathtub by two hinges 4. As one can see in FIGS. 1 and 2, the door opens toward the interior in such a say that when it is closed its side edges and its lower edge overlap the edges of the opening 2.
  • the door has on its two side edges and on its bottom edge a throat or channel 5 in which there is pressed an elongated sealing strip 6 in sponge rubber of rectangular section.
  • This strip is fastened to stay in the channel 5 and, when the door is closed, presses against the parts of the inner wall of the bathtub which surround the opening 2.
  • a handle 7 and a latch 8 permit fixing the door in the closed position, the sealing strip 6 being then strongly compressed between the door and the inner wall of the bathtub.
  • the bottom of the bathtub is provided with a drain orifice 9.
  • this orifice is provided with a removable closure which cannot be put in place unless the door 3 is closed.
  • the closure consists of a metal tube the length of which corresponds to the total height of the bathtub and the lower extremity of which is so adjusted as to engage in the entry to the drain orifree 9. That orifice being located immediately behind the door, one sees that the tube 10 cannot be put in place except when the door is shut. Additionally the upper extremity of the tube 10 which is provided with lateral openings plays the role of an overflow and prevents the tub from being filled above a certain level.
  • a cap covers the orifice.
  • the tube 10 can be connected to the door by brackets 11 and 12 in which it can slide.
  • a stem 13 permits the tube to be locked in the open position above the upper bracket 11.
  • the bathtub described above is intended to be associated with the usual faucets, not shown, comprising a mixing faucet regulatable to have a large flow.
  • the bathtub as described has been made in sheet metal to the following dimensions: Length 1,325 mm; width 680 mm; height 700 mm. In certain cases it has been found that it was advantageous to make the body of the bathtub and the seat of plastic material, for example, in polyester.
  • the frame of the door as well as the hinges are in this case still of metal, the borders of the frame being embedded in the polyester.
  • the door can also be placed in one of the longitudinal side walls of the bathtub.
  • a rubber gasket having a cross section which is composed of a semicircular head and a body in the form of a Y can be used.
  • the two upper branches of the Y are connected to the extremities of the arc of the circle of the head and this construction gives equally good results.
  • Such a cross section can be easily placed around the periphery of the door, the body of the Y being pressed between two fixed parts of the door in such a way that the head of the section projects from the front surface of the door in lieu of the piece 6 shown in FIG. 3.
  • the alternate construction presses against the wall of the bathtub when the door is closed.
  • Making the door on the inner side has the following advantage.
  • the pressure which the water exerts on the door when the bathtub is partially or entirely filled aids in sealing the door against water leakage out of said bathtub and makes it practically impossible, even by mistake, to open the door.
  • the latching hardware that keeps the door closed can also be placed on the outside of the door. Thanks to the simplicity of the means which insure the water tightness, and the security that comes from the simple fact of locating the door on the interior of the tub permits the tub to be mass produced at a very low price.
  • a bathtub having enclosing side walls and a bottom wall, one of said side walls of said bathtub defining an opening, a
  • 1 door having an interior wall surface and capable of closing said opening, means mounting said door such that said door opens by pivoting about vertical hinge means on said side wall inwardly toward the interior of the bathtub and water pressure exerted on said interior wall surface of said door aids in sealing said door from leakage of bath water from said bathtub through said opening, and removable closure means for a drain orifice located immediately behind said door.
  • a bathtub according to claim 1 in which the opening is generally rectangular, the lower edge thereof being located at a level higher than that of the bottom of the bathtub, said door comprising a panel similar in shape but larger in area than the area of the opening and resting on three margins against the defining edges of the opening.
  • a bathtub according to claim 3 in which a sealing strip is interposed between the margins of the door and the defining edges of the opening.
  • a bathtub according to claim 4 in which said sealing strip is disposed around the margins of the door, the cross section of said sealing strip including an arcuate head and a Y-shaped body, the two branches of the latter being connected to the extremities of the arcuate portion which presses against the defining edges of the opening when the door is closed.
  • said removable closure means further comprises means defining a drain orifice at the bottom of the bathtub and to the rear of said door and drain stopping means movable from a drain open to a drain stopping position within said drain orifice, and stopping means preventing the opening of the door when it is in drain stopping position.
  • a bathtub having enclosing side walls and a bottom wall, one of said side walls of said bathtub defining an opening, a door having an interior wall surface and capable of closing said opening, means for mounting said door on the interior surface of the side wall defining the opening to close said opening, and removable closure means for a drain orifice located immediately behind said door.
  • said removable closure means further comprises a drain orifice at the bottom of the bathtub and to the rear of said door, and a drain
