3 Claims, 4 Drawing Figures PORTABLE BATIITIJB BACKGROUND OF THE INVENTION This invention relates to a new and novel portable bathtub.
Portable bathtubs have heretofore been devised for bathing persons in bed or the like. For example, US. Pat. Nos. 755,747, 1,451,437 and 3,373,451 relate to such devices. The structures shown in these listed patents are not entirely satisfactory, however, because no provision is provided for readily placing a person therein or too of providing a structure which permits it to be conveniently and safely supported on a carrier such as a wheeled stretcher. An urgent need thus exists for a portable bathtub structure which has versatile use in hospitals, rest homes and the like where patients are bedfast or otherwise have difficulty in bathing in a conventional tub or shower. I
SUMMARY OF THE INVENTION According to the present invention and forming a primary objective thereof, a portable bathtub is provided having a novel structure which facilitates its convenient use with patients who otherwise find it difficult to bathe.
More particularly, an object of the invention is to provide a portable bathtub having a novel frame and flexible liner which can be supported either on the top of a carrier surface such as a conventional wheeled stretcher by leg means thereon or be draped over the stretcher surface by the liner with the frame and legs hanging down alongside the stretcher, whereby a patient can be moved directly from the bed onto the stretcher for bathing. Such object is accomplished by an enlarged dimension of the frame relative to the carrier surface and by a pivotal attachment of at least two of the legs which are contoured so that when pivoted toward a center position, the frame of the bathtub is supported on the top of the carrier surface but when rotated away from center the said frame and legs can hang down alongside the carrier to allow the liner to lie flat on the carrier surface similar to a sheet.
Another object of the present invention is to provide a novel frame structure which is constructed of several pieces for compactness in shipping and storage. The
frame also has a novel assembly with the supporting legs and in its assembled condition is capable of use on substantially any width of stretcher.
Still another object of the present invention is to provide a novel flexible tub liner for support on a frame, including a novel drain facilitating connection to existing drain means.
The invention will be better understood and additional objects and advantages will become apparent from the following description taken in connection with the accompanying drawings.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT Referring in particular to the drawings, the portable bathtub of the present invention comprises an open center frame 10 preferably made up of a pair of tubular side pieces 10a and tubular U-shaped end pieces 10b. The ends of the side pieces 10a have telescoping engagement with the arms of the end pieces 10b for assembly. Although no particular telescoping arrangement is important, the drawings show the end pieces telescoped within the side pieces 10a, it only being desired that the length of telescoping; relationship be sufficient to provide a rigid longitudinal connection.
Each of the frame pieces 10:: and 10b has vertical apertures 12 for receiving legs I4. These legs have an upper spindle portion 16 adapted to extend up through the apertures I2. Since the legs extend through both the apertures in the side pieces 10a and end pieces 10b,
the respective frame pieces Ma and 10b are held together thereby. The spindles I6 have a pivotal connection in the apertures so that the legs can be rotatably adjusted for a purpose to be described. A portion of the leg spindle 16 projects above the frame and has an end cap 1.8 thereon.
Each of the legs has an angled portion 20 which vertically offsets the bottom support end 22 of the leg from the spindle portion 16 for a purpose to be described hereinafter. Preferably, each leg has a leg holding band or washer 24 at the lower end of the spindle H6. The lower ends of the legs have end cups 25 in a usual manner.
A flexible waterproof liner 26 is carried inside the frame 10 and has a portion 28 which extends over the top of the frame. Mating snap members 39 are provided on the body portion 26 of the liner and on the portion 28 so that the latter upon being folded over the frame can be connected to the body portion of the liner for holding the latter on the frame.
One end of the liner 26 has a drain fitting 32, best seen in FIG. 4, comprising a top flange 34 having a watertight secured connection to the liner. A projecting threaded portion 36 of the fitting extends down through a suitable aperture in the liner, and this projection is constructed for threaded connection with a female hose fitting 38 of a conventional drain hose 40. A stopper 42 is provided to plug the fitting 32 when the tub is in use.
The present bathtub is versatile and convenient in its usage. To assemble .the tub, the frame parts are fitted together in their telescoping relation and the legs inserted to hold the frame portions together. End caps 18 and 25 are also applied. The liner is then placed inside the frame it) with the portion 2% extending down over the outside of the frame and connected to the body of the liner by the snaps 30. The drain hose is brought up through the hand holds and threadedly connected to the drain fitting 32. With the stopper 42 in place, the tub can be filled by any suitable means, and upon completion of the treatment for the patient, the stopper is removed and the tub drained. 7
One important feature of the present portable bathtub is that it can be used on a conventional wheel type stretcher. Such a stretcher is shown in FIG. 2 and is designated by the numeral 4d. As is well known, such stretchers have a top surface 46 supported by a wheeled frame 48. By using the present bathtub structure on a stretcher 44, the facilities of a bath or other treatment can be taken directly to the patient if necessary. Furthermore, a bedfast patient can be placed in the tub with ease. That is, in this latter regard, wheeled stretchers are usually of the same height as a bed, or too the bed may be vertically adjustable, so that a patient can be slid directly from the bed onto the stretcher or vice versa. In applicants bathtub structure, the inner dimensions of the frame 10, both in its length and width, are greater than the stretcher surface and the contour of the legs is such that when turned inwardly they engage the stretcher surface and support the tube on the said stretcher surface. When the legs are turned outwardly, however, the frame and legs hang down from the liner below the stretcher surface, the liner being draped over the stretcher surface as shown in phantom in FIG. 3. With the stretcher placed up against the side of the bed, and the tub lowered, a patient can be slid over onto the stretcher on top of the liner. Thereupon, the frame is lifted and the legs turned inward for engaging the top of the stretcher. The tub can then be filled or the patient treated as necessary, assuming of course that stopper 42 has been put in place. After treatment, the liquid is removed by taking out the stopper. The frame is lowered by rotating the legs again to their outward position to hang down alongside the stretcher. The patient can then be slid back into bed.
The structure of the present bathtub has many other features in its construction and use. For example, the frame and liner arrangement make it such that the full weight of the patient is on the supporting surface, not on the tub, so that should one or more of the legs accidentally be displaced from the top surface of a stretcher the patient would remain on the stretcher, there possibly at worst being only a partial loss of water from the tub. Another feature is that the present tub can be placed on the floor for ready access to a patient who can get out of bed. Also, the tub can be disassembled for easy cleaning and also for convenient shipment and storage. The liner 26 is constructed of any suitable material which is durable, is resistant to disinfectants or other cleansing chemicals ordinarily used in hospitals or rest homes. The present bathtub can also be used conveniently to bathe a patient in a bed. Such is accomplished by first removing the four legs, then sliding the frame with the liner therein under a patient, and then lifting the frame and reinserting the legs.
It is to be understood, that the form of my invention herein shown and descibed is to be taken as a preferred example of the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of my invention or the scope of the subjoined claims. For example, it may not be necessary that all the legs 14 be pivotal since by suitable contouring of at least two of the legs, it may be possible to lower the frame down by turning such two legs outwardly. With all the legs being pivotal, however, the present frame can be supported on practically all existing wheeled stretchers and also can be laid flat thereon with the legs extending down alongside the stretcher. Although the device of the invention is termed a bathtub, it is to be understood that it may have any other use which requires a wet treatment or the like.
Having thus described my invention, 1 claim:
1. A portable bathtub comprising an open center horizontal frame, a flexible liner member mounted on said frame arranged to form a receptacle to receive a person, and a plurality of support legs connected to said frame in depending relation and having bottom support ends, said legs being pivotally attached on a vertical axis to said frame at their upper ends, said legs being angled from their connection with the frame and the bottom support ends being adjusted in a lateral position relative to the frame upon selected rotative positioning of the legs.
2. The portable bathtub of claim 1 wherein said frame is composed of telescoping sections facilitating compactness in shipment and storage, said telescoping sections having apertures for receiving the vertical pivot attachment of said legs, said apertures being provided in said sections at telescoping portions thereof whereby the vertical pivot attachments of said legs serve to connect said sections together.
