An object of this invention is to produce a device within the means of an average family for bathing arthritic or other partially incapacitated persons in need of bathing treatment.
Another object of this invention is to render it simple and easy to move a patient from a bed and place the patient in the tub preparatory to receiving a water treatment.
Another object of this invention is to provide such an apparatus whereby it may be easily transported from one place to another and :Whereby it may be collapsed or folded so as to take up a bare minimum of space.
I Another object of this invention is to bathe a partially or totally incompacitated person easily and conveniently and also to transfer that patient or a similarly incompacitated patient to a standing position safely and easily, both of these functions being performed preferably by the same structure.

As stated previously, the invention has for its main purpose the alleviation of both trouble and expense involved in treating patients whose motor reaction and agility are impaired when the prescribed treatment involves bathing and/or very light exercise. Accordingly, a eneral description of the operation and suggested mode of utility of the device is set forth at this time.
The portable bath apparatus is adapted particularly for use of individuals having arthritis or similar afiiictions such as polio or its effects or, having any illness requiring baths or meticulous handling. The apparatus has three main purposes. The first is the convenient and safe means of handling and bathing such patient in his own room; the second is an economical and convenient means of hot or cold water treatment which is very often recommended to such patients and the third is the safe means of helping such patients from a prone position in bed to a standing position and of course, from a stand-' ing position to a prone position in the same bed or another bed when the patients are to be moved 'from one place to another.
Light exercise is usually recommended for arthritics, which means that patients must be helped from the bed several times a day. This is very difficult, especially for those who care for the many cases involving to the patient.
The bath apparatus, which is both light and portable, is used in the bedroom oralongside the bed of the patient. Three lengths of hose or conduits are provided; two for water supply (hot and cold) and one for draining the tub. The drain hose is suggested to be hooked over the shower stall, bath tub, toilet in the bathroom or any other suitable drain employed for any water.
The water supply is taken from the bathroom or other faucets.
These hoses are installed permanently to the risers or removably attached to the faucets by means of conventional couplings. The other ends of the hoses are attached to the mixing faucet which is attached to the tub of the portable apparatus.
The apparatus is placed close to the bed, standing on the rollers which are at one end of the tub of the apparatus. First, the two catches which hold the undercarriage or support to the bottom of the tub are released. The top of the undercarriage or support is then-brought to a with the tub. One end of the support or under-.
carriage is secured to the bottom of the tub by means of one or more hinges. This makes it'possible to erect the undercarriage with all four legs in place on the floor, while the: tub itself is. still standing on the rollers provided at one. end.
Next, the tub is pulled down to a horizontal position, the two catches under the tub being locked to the undercarriage in order to hold the tub firmly in place. The water supply hoses are their attachedas previously described. On one side of. the bath tub: adjacent the. bed, the two pins which look the hinged side of the bath tub to; theends of the said tub are. released. The hinged, side of the tub is then lowered to the rest; horizontally on the bed. A patient board,
which may be oi marine plywood or other suitable material is provided which. is of expeditiously chosen size so as to fit within the tub and so as to support an average, bigger than average and smaller than average patient. It is usedto move the patient from the bed into the tub .and also for moving the patient from the tub into; the bed. This board has an attached cover of sponge rubber, which has a non-porous sur- ..face. This eases the pain. caused by moving the patien 7, On each side of the board there are two pieces of tape which are used as follows; the board is pulled out of. the tub and onto the bed as close to thepatient as is practically possible. If possible, the patient is rolled. on his side with his back toward the tub. With the board as close as possible, the patient is rolled on the board.
Tapes arethen placed across the tub and the. assistant walks around to the. other side, picks up the, tapes, pulling the. boardand patient into the bathtub easily over the small rollers which are placed onv the bottom of the tub and on the hinged side for. this purpose. The board;b eneath the patient is now secured tothe lifting mechanism at the head of the tub. The crank at the. top of. the. lifting. mechanism is then turned, raising the, head of the board about five inches. With.- theboard, on this angle, the patients iacewill be I above. the water line when theltub is filled.
The next step is to close the hinged side and place the locking pins so as to holdv it closed. The safety bar which is attached with a bolt to the. top edge of the stationary side of the tub is then swung across the opposite side, where thereare-two catches located on the top edge of the hinged side of the tub. The assistant presses the bar down against the catches, where they are; snapped into locked position. The end of the, bar hasfa flattened portion and is turned. down approximately one half inch. This turned down part engages over the outside edge of the hinged side of the tub in order to help arrest. the pressure of the water against the tub.
v As the. next step, the cords. running through the grommets in the waterproof material. which is attached to the end of the hingedv side andto the end of the tub, are drawn up and tied at both ends of the tub. The waterproof material which covers the entire hinge connection between I the hinged side and the'bottom of the. tub joins these waterproof ends, forming one continuous waterproof unit.
A short piece of hose is connected to the mixing faucet. This hose is placed alongside the patient with the open end at the foot of the tub. Before the water is turned. on, the drain plug is placed. This drain plug isalso the overflow which controls the water line.
The tub is now ready to be filled to the water line. When the tub is filled, a showerhead is attached to theshort hose. It is used to bathe the patient and to rinse the tub after the bath is completed,
If a long hot water treatment has been prescribed, the hot water 'is turned on slowly and regulates the temperature. Any excess water is carried down through the overflow drain plug. When the bath is complete, the overflow plug is removed and the water is drained from. the tub. The cords are then untied and the pins are removed allowing the. hinged side to be. lowered on the bed.
The board containing the patient is still on an angle. While the patient is being, dried, most of the drops of water will run. out the non-porous rubber cover on the topside of the board as well as ofi the underside. The crank of the lifting mechanism. is then turned to allow the boardto be lowered flat on the bottom of the tub. The
board is. then disconnected from the lifting. jack or mechanism. The tapes which are fastened to the board are then placedacross the bed. The assistant then goes to the opposite side of the bed, pulls the tapes and returns the patient to the bed.
As the board is pulled. from the. tub, the. squeegee 'which runs thev entire length of the tub squeezes the remaining water" from the bottom of the board, thus keeping the bed dry.
The board is then lifted from the bed and placed in a suitable location remote from the device. The hinged: side of the tub. is then closed 7 and the tub is washed out, preferably with the showerhead': The board is then placed in the f tub andwash-ed; following which it is tipped on ed'geandboth the board and tub receive final The catches under the tub are released, and lfitrinsing.
The board is then placed right in the tub.
ing springs which form a part of the undercar- After the two has remainedin this position for The tub is then stood on end, and the undercarriage is foldedflat against the bottom of the tub. Of course, the drain hose is disconnected prior to-standing the tub onend, the hose: being suitably caredforafter disconnection. The -faucets which supplied the water tethe tub are now closed, the supply hosesdisccnnected and their ends are placed in the tub. or shower in the: bathroom. The hoses are thendisconnected from the portable bath one at atime, emptied ofwater as they are-coiled, and then placed inthe portable bath tube. The tub is then rolled'into a corner of the room or some other convenient place for storage:
The same apparatus. is used for a means of "taking a patient from a, bed to a standing position and vice versa. When the device is. used and placedhorizontally on the bed. "Theiboard is pulledcut of. the tub: and. placectnext; .to-i the patient, who is placed on the board and pulled into the tub, as formerly described.
- assistant then gives the crutches to the patient, releases the safety bar and assists the patient down the ramp to the floor. In order to return .the patient to the bed the same procedure is reversed.
The structure involved in performing these functions is as follows: A support or undercarriage generally indicated at I consists of four legs I2, I4, I6, and I8 respectively. A substantially square frame having sides 20, 22, 24 and 30 respectively is secured at the upper ends of the legs thereby forming a table top. Frames or gates 32 and 34 respectively are hinged by means of the collars 38 to the legs I4 and I8 respectively. These gates have means operatively connected therewith for releasably latching them to the respective legs I6 and I2. The latching means is seen best at Figures 8-10. Since both latching devices are identical, a single description suffices for both of them. The
' structures secured to the gate 32 includes a piece of angle iron 40 with a pin 42 passed therethrough and also through a part of the framing of the gate. This pivot pin has a function of a latchkeeper in that the latch arm 44 is provided with a notch 46 which is to be removably disposed thereon. The head of the pin 42 prevents sliding movement of the latch arm 44 from the pin 42. A sliding latch 48 with notched tongues 50 and 52 respectively extendin therefrom is disposed on one flange of the angle iron 40 and is adapted for reciprocating movement. A pair of slots 54 and 56 respectively are provided therein accommodating the screws 58 and 60 which restrict within limits reciprocatory movement of the sliding latch 48.
The leg I6 has an angle iron piece 62 fixed thereto by welding or the like. A latchkeeper 66 which has a pair of spaced openings 68 and I0 in the bight I2 of a curved portion thereof, is fixed to the angle iron piece 62 in parallelism with the sliding keeper 48. Accordingly, when the frame or gate 32 is moved pivotally about the collars 38 as an axis, the cam portions of the tongues 50 and 52 are adapted to slide over the lower edges of the notches 68 and I0 so that the notch tongues are held in place thereby preventing undesired hinge movement of the frame 32.
The latch arm 44 is pivoted by means of a screw 76, rivet or the like, which passes through a bifurcated bracket I8. The bracket I8 is in turn fixed to one of the flanges of the angle iron piece 62 and at the proper elevation so that the latch arm 44 fits over the keeper pin 42.
The legs I2 and I4 are connected together by means of spacing rods, each of which is indicated at 80, while the legs I8 and I6 are connected together by identical bracing rods 80. Accordingly, when both of the frames or gates 32 and 34 are unlatched and folded inwardly, the legs I2 and I4 are free to pivot as a unit, while the f legsIB andI8 are free to pivot as a unit. Corner brackets 84 --and 86 respectively are riveted or otherwise rigidly :fixed to corners of" the frame I 20 immediately above the legs I2 and I4. These legs are pivoted by means of suitable pins to the angle brackets whereby the two legs I2 and I4 are capable of the described pivotal movement. The legs I6 and I8 have the plates 90 and-92 respectively pivoted thereto, while the appropriate end of the frame 20 rests on the top of the legs I6 and I8, whereby the legs I6 and I8 are capable of pivotal movement about the pins which pass through the plates 90 and 92. Accordingly, the tub generally indicated at I00 is fixed rigid with the plates 90 and 92 by means of pivotal bolts or the like which pass through the rails I02 and I04 of the tub. Accordingly, when the tub is in the horizontal position it is adapted to rest on the frame 20. But when the tub is in a vertical position the legs I4 and I2 may be moved as a unit against the bottom of the tub and the legs I6 and I8 may also be moved against the bottom of the tub so as to collapse the undercarriage or support for the purpose set forth previously.
Reference is now made primarily to Figure 1 wherein the tub I00 is ilustrated. This tub includes a bottom I06, a side I08, a second side IIO, a head or upper end I I2 and a lower or foot end H4. The foot end is provided with a number of casters or rollers II6 so that the tub together with its suport may be moved from one place to another conveniently.
The side H0 is connected with the bottom I06 by means of one or more piano-type hinges I20. One leaf I22 of the hinge illustrated in Figure 6 is secured to the bottom I06 while the other leaf I24 is secured to the side H0. A Water-proof covering I28 is disposed around the hinge and tucked under the leaves thereof so as'to provide a water tight connection between the side Y by means of a clamp strap I36 and a number of ing (see Figure 13) bolts I38. The function of this resilient member is that of a squeegee for cleaning water of the patient board I40 (Figure 1) as it is moved thereover.
Flexible end members I42 and I44 which are also resilient and water-proof, are secured to the ends H4 and H2 respectively and also to the end edges of the hinged side IIO of the tub. These side pieces form a continuation of the cover I28 (see Figure 13) so as to prevent leakage. A vertical strap I50 is secured to the inner edge of each flexible end piece pressing it firmly to the appropriate end of the tub. Rivets are used in holding the strap I50 in place. These rivets also pass through the bottom fram- I54 of the end H4 and a similar construction is provided in connection with the end II2.
An identical arrangement including a strap I50. is used for holding the edge of each flexible end piece I42 and I44 to the ends of the hinged side IIO of the tub.
A draw string I60 is passed through successive grommets in the end piece I42 while an identical draw strin I62 is passed through grommets successively placed in the end piece I42.
When the hinged side I I0 is moved to the vertical position, that is, parallel to the side I08,
- the draw strings I60 and I62 are pulled-so as to hold the flexible end pieces-in place (see Fig- Q J E-tlis'a eYelrmainta einadminpiee 30A 5' sltion that it is parallel to the side 3 08, pins l-66 are passed through the 'ap'i tured lea-f 11:10, one or which is secured to :each end H2 and 2| M of the tub. These pins 1 66 also pass through sleeves H2 which are welded or otherwis'e fixed .iimmovably to the upper edge f the l inged side Jlfll. Hence, these ends or the side 1110 are Zheld .releasalbl-y in pl'a'ce with respect to the ends "H2 and l l hoi the mh A chain 1 16 or dtherfequivend portion 1'88 "at substantially right angles ito the longitudinal axis of the bar 190.
