This invention relates to bath apparatus to enable invalids, handicapped or aged persons to bathe ina conventional tub and to readily position and lower themselves into the tub'and to mechanically lift and remove the person there-- from, after bathing.

It is an object of my invention to provide a simple, rugged and easily operable invalid supporting and. handling apparatus for bath tubs to enable a feeble or handicapped person, from a position outside of the tub, to be supported and shifted into a position over the tub and thereafter, lowered and at least partially immersed in the bathing Water, all subject to control and operation by the user.

Fig. 3 is a vertical section taken centrally through the upstanding support-operating mech anism and chair with the same disposed in lowered position within the tub;

A further object is the provision of a device or apparatus of the class described wherein a body support or seat is readily shiftable from a receiving position outside of and above the tub to a position over the tub and'thereafter, may be lowered by the user to submerge at least a portion of the body into the water of the tub and which thereafter may easily be elevated and shifted to a position outside of the tub for delivery.

More specifically, it is an object to provide bath apparatus for supporting and handling incapacitated persons, which is adapted to be readily and compactly installed in conventional bath rooms, preferably adjacent oneend of the tub and which utilizes an upstanding support mounted for shifting movement generally in a line of travel traversing the bath tub and wherein said support comprises a pair of relatively longitudinally adjustable sections, one being mounted on the other for vertical adjustment and carrying a laterally extending support or seat upon which the body of a feeble person may rest.

A still further object is the provision of apparatus of the class described wherein efiicient hydraulic mechanism for elevating'and lowering the invalid support is supplied and mounted within the confines of the two sections of the supporting post or structure. and is readily controllable by the user from a position convenientl accessible to the support or seat.

These and other objects and advantages of my invention will more fully appear from the fol lowing description made in connection with the accompanying drawings wherein like reference characters refer to similar parts throughout the several views and in which:

' I Fig. l is a side elevation of aniembodiment of my invention mounted in a bath room for cooperation with the conventional bath tub and Fig. 4 is a cross section taken on the line 44 of Fig. 3;

Fig. 5 is a horizontal cross section taken on the line 55 of Fig. 3;

Fig. 6 is a top plan view of the two-section supporting structure showing a control mechanism for opening the seat-lowering valve;

Fig. '7 is a view mostly in side elevation with some parts shown in vertical section, illustrating another embodiment of the invention mounted .on the wall for horizontal shifting movement transversely of the tub; and

Fig. 8 is atop plan view with some portions broken away, showing the structure illustrated in Fig. 7

Referring now to the form of the invention illustrated in Figs. 1 to 6 inclusive, an embodiment of my apparatus is shown as operatively installed in a corner of a bath room above one end of a tub 'I, being supported as shownfor swinging movement in an arcuate line of travel transversely of the tub through a suitable medium such as the vertically spaced, angled. supporting brackets Ill and H, to which horizontal supporting arms [2 and iii are pivotally connected through heavy hinge pintles I2a and [3a respectively. An upstanding, two-section sup-' port or post is connected with the horizontal supporting arms I? and. 13, comprising as shown, a

' pair of complemental, heavy sheet metal chanrigid supporting arms l3 and I2.

nel members M and. [5 respectively, the inner or rear channel member I4 being rigidly secured at its top and adjacent its bottom ends to the Connection of the arms l2 and I3 is made with the rear or intermediate web of channel member M by weld.- ing or otherwise rigid and durable structure. The outer channel member I5 is compactly telescoped about channel member M with the intermediate web thereof disposed forwardly of the supporting post structure and covering or partially covering the open face of th channel I4. I prefer for reinforcing and connection purposes, to provide the outer telescoping section I5 of my supporting structure with inturned longitudinal flanges 5a which overlie the rear corners of the back web of inner channel section l4.

To facilitate substantially vertical adjustmentof the outer channel section I upon the inner section ii, I provide two sets of rollers between opposing faces of the two sections adjacent the forward side of the supporting structure. To this end, as shown in Figs. 3 and 4, a short, transverse roller shaft [6 is journaled or otherwise mountedin the opposing parallel legs of inner channel member I4 adjacent the lower end thereof and has mounted thereon, a pair of spaced v rollers 16a having the forward portions of their periphery extended somewhat beyond the inturned, reinforcing flanges I la at the forward open face of channel l4. Rollers 16a carried by the inner channel bear against the inner surface of the intermediate and forward web of the outer channel [5.

The second pair of adjustment-facilitating rollers as shown in Figs. B and 3, is mountedon a short, transverse roller shaft ll which extends through a bore formed. in a thick attachment block I8, bolted by'a bolt 19. or otherwise rigidly afiixed to the intermediate web or: outer face of the outer channel section and disposed adjacent the upper end of said outer. channel. section:

- The two rollers Ila mounted on shaft Hi of the outer portions of their peripheries; bear' against longitudinally extending grooved'seats Mb which throughout at least the upper half of the inner channel member 14 are formed by L-shaped flanges connected with the wider andside faces or legs. of the. inner channel section. hi (see Fig A body support, seat or chair' ismountedl upon. the lower portion of; the. outer channel section k5,.havin'g as shown a generally rectangular and horizontal seat frameZO which may conveniently. befconstructedfrom rigid. tubular material. and which has: its rear and as shown; somewhat diminished end a afiixed to a relatively wide depending supporting hook 2| welded or otherwise rigidly afiixed to the front face of intermediate web and lower portionof the outer channelsection I5. Seat frame 2!]. may conveniently have stretched longitudinally over the ends thereof, a flexibleseat-forming fabric 20c. The sup.- portas shown, includes aipair of diagonal bracing members 22: interconnected at their upper ends preferably by integral tubular construction with a horizontal top member ZZawhich is welded or otherwise rigidly aflixed. to the intermediate portion of the forward, upstanding face of the outer. channel section I5. If the'diagonal members: 22' are integrally formed with thetop piece 220;, the :ends of the tubular members may be bent to form horizontalsections 2211 which are rigidly interconnectedas by welding with the tubular side pieces, 20b3of the support frame and thereafter, may be bent diagonally andupwardly and thereafter, curved and bent rearwardly tov form chair arms 22c to protect and assist in re-- Efiicient and readily operable elevating means are housed preferably within. the confines of thetelesooped channel sections M and i5" and preferably, but not necessarily, comprise a hydraulic:

jack mechanism having asubstantially vertical. fluid cylinder 2-3 rigidly afiixedvas by welding at its lower and somewhat reduced end 23a to the inner face of the mounting block l-Bmigidly-affixed to the intermediate and forward web of the outer channel section l5. Theilpper and enlarged portion of cylinder 23 contains a hydraulic fluid while the lower somewhat reduced portion thereof acts as an elongated slide bar for receiving the hydraulic piston rod 24 which extends downwardly therefrom and, has'its' lower end removably affixed as shown, by a bolt Zflato a transverse mounting block 25 welded or otherwise rigidly aiiixed within the lower portion of the inner channel section ill at a short distance above the lower end thereof and above the rollers I6a carried by the inner channel section.

Thehydraulic jack is for the most part, of conventional hand pump construction, havinga threaded air release valve 26 in the upper end of cylinder 23 and is provided with a laterally and forwardly extending lever or pump handle 21 extending at some height above the top of the sup port or'ch'air. with. the inner end of said handle fulcrumed: between suitable. lugs 23b provided; at the lower end of: cylinder '23: and having connedtion .(notshown) in. conventional mannerwith a check valve controlled piston mounted: interiorly of the cylinder. The pump handle 2? for convenience of the usermay have hinged tothe outer end thereof,.a depending straight handle extension 2Tawhi'ch terminates in a hand grip Z'Tibdisposed" adjacent'the back of..the chair formed bythe frame 22. The action of the pump is to inject rom. the hydraulic contents'o'f cylinder 23, fluid Figs. 1, 3 and.6, the stem of the valve 26 is provided with a radial lever arm 26w which is connected. at its outer end by aflexible cable-28, with a.small"pull' knob 29, shown as mounted on one of the arm 22c of the chair, The cable or cord 28 as shown, extends downwardly and forwardly from the lever arm 28a of the valve, passesthrough a smooth guide formed in a guide arm 30 and then extends downwardly through oneofthe diagonal tubular portions 22 of the chair back and passes forwardly through the arm 22c and then. upwardly through an aperture cut inthe rear portion of said arm and is secured to the knob 29. An upward pull upon the knob 29 opens valve 26' against the yielding action of a coil spring 3i which has one end connected with the rear portion of the lever arm 26a and has its other end secured to a retaining lug 34a mounted on the top of cylinder 23.

It will be noted that with my structure, the two-section, upstanding support is mounted in somewhat declined relation to the vertical and with the cooperation of the short horizontal supporting arms 12 and I3, and the spaced wall brackets I 0 and l l may be conveniently attached toa wall of the bathroom adjacent oneend of the tub (preferably the lower end) and may be swung to the dotted line position shown in Fig. 2, where the greater portion of the support or chair is dis posed outwardly of the bath tub and furthermore, may be swung over the end of the tub to the full line position shown in Fig. 2 and thereafter, lowered to the bathing position shown in Fig. 3'.

Operation In use, the invalid, through the use of a wheel-' chair, assistance or cane or crutches, is able to shift his weight to the support; afforded by the four-sided frame with his limbs extending forwardly and in most instances with his torso disposed between the arms of the chair and supported bythe flexible back. Thereafter, with the assistance of his hands or legs, or if necessary, with the assistance of an attendant, the supporting structure with the weight of the invalid thereon-is swung over and above the lower end of the tub to the positionshown in Fig. 1. Thereafter, the user may release the valve slightly to let out air from the upper portion of the cylinderand produce a gradual lowering of the outer channel section l5 of the support relative to the inner channel section l4. In the form shown, this may all be controlled by the user by pulling upon the valve control knob 29. Upon release of the knob, valve 26 is closed and the chair with the weight of the users' body thereon, is retained in the desired adjusted position such as for example, the lowered position for bathing shown in Fig. 3.

Upon completion of'the bath, the user, assuming he or she has the control of at least one arm, may actuate the pump handle 2'! from the depending auxiliary rod 210. to reciprocate the pump, forcing fluid against the top of the piston rod 24 to elevate the cylinder 23 since the lower end of piston rod 24 is fixed to the'fixed support block 25 secured to the inner channel section !4 of the supporting post.

This action progressively elevates the outer channel section l5 rigidly secured to cylinder 23 to a point where the bottom of the invalid supporting structure 20 is disposed above the top edge of the tub, as shown in Fig. l.

Thereafter, the invalid or an attendant may swing the entire supporting structure and post structure to the position shown in dotted lines in Fig. 2 for delivery of the user at the side of the tub.

From the foregoing description, it will be seen that I have provided a compact, rugged device or apparatus for enabling'an infirm person to get into and out of a conventional bath tub without requiring the support of his Weight'on his own limbs alone. [It will further be seen that with my structure in most cases, the invalid may pull and draw himself to the support under his own power, thereafter control the swinging of the supporting structure and lowering of his body into the tub for bathing, as well as controlthe sub- I sequent elevation and shifting of the support to get out of the tub.

It will further be seen that with my structure, the device may be readily applied to a vertical supporting Wall in the-bath room without requiring expensive and bulky supporting pedestals, davits or other suspension means. The entire elevating mechanism is compactly mounted within the hollow, double channel post and is not in an obstructing position or one requiring addi tional space in the bathroom. Thecombination of the two-section post with its supports for transverse shifting movement enables the post to be swung or slid as the case may be in very close position to a supporting wall but to nevertheless align the lower end of the post inclined from the vertical for lowering of the invalid support into the tub. I

In Figs. 7 and 8. I illustrate another form of the invention applied to a conventional bath tub wherein the two-section supporting post structure'and the invalid support or chair carried at the lower end thereof, is slidably shiftable along a track secured to the wall in a transverse, elevated position above the lower end of the tub.

In this second form of the invention, the supporting post structure comprising inner and outer channel sections [4 and 15, the hydraulic operating mechanism, the invalid support 20 and chair structure and controls, are all identical with the the structure shown in Figs. 1 to 6 and therefore, do not require detailed description. I have not illustrated the pump handle for actuating the hydraulic mechanism or any means for facilitating opening of the air release valve.

In placeofthe swingable mounting for the two-section channel support post, Ixprovide in this second form, an upper roller-equipped bracket 35 having a depending attachmentarm 35a which is welded or otherwise rigidly secured to the rear face or intermediate web of the inner post channel I 4 and which has angularly positioned and integrally formed therewith at its upper end, a roller carrying head 35b whichis confined within a suitable, substantially horizon tal-track made up of a pair of channel sections 36 and 3'! respectively. The head 35b1is inclined from the horizontal and carries adjacent its ends, pairs of rollers 33 disposed on opposite sides'oi the head and having the edges thereof bearing against the longitudinal, turned flanges or portions of the track sections 36 and 31, as' clearly shown in Fig. '7. Thus, it'will be seen that the two-section post structure, is supported in a position declined from the vertical and that the'support and thrust is imposed upon the flanges or channels of track sections 36 and 51 in an outwardly and downwardly direction. Y

At the lower end of the two-section post, a rigid bracket 39 is ailixed to the rear web or inner channel section it extending horizontally and rearwardly therefrom and terminates in a head somewhat similar to the head 35b of the first mentioned bracket which carries a pair of widely spaced rubber rollers =40 rotating on vertical axes and mounted for bearing against the bath room wall W. I

With this last described form of my invention, the weight of the supporting structure and invalid is mainly taken by the sup-porting track compris ing channel elements 36 and 31. The nature of the structure is such that a rearward thrust, when the invalid is supported, is imposed'upon bracket 39 causing the rollers 43 to be thrust against the vertical wall W. Supporting post structure and chair as an integral unit, may readily be caused to slide from a position beyond one of the longitudinal sides or" the tub to a posi-' tion over the lower end of the tub. Theoperation of .this hydraulic elevating and lowering mechanism is similar to that described in the first adjustable channel member and extending for-I wardly and laterally thereof for disposition above the top of a tub and for immersion into the contents of a tub, mechanism interposed between said channel members for raising and lowering said adjustable channel member, mechanism connected with. the other of said channel members'for securing and supporting the structure from a. vertical wall with said post declined from the vertical and with the upper end thereof disposed in close: relation to said wall and with the lower-end thereof aligned for lowering into the tub,.said mechanism including means for shifting said structure generally in a line of travel transversely of a bath tub.

2. Invalid supporting and handling'apparatus for bath tubs having in combination an upstanding supporting post comprising a pair of relatively longitudinally slidable sections, one being mounted on the other for vertical adjustment, an invalid support secured to said vertically adjustable section and extending forwardly and laterally therefrom for disposition above the top of. a tub for immersion intothecontents of a tub, mechanism interposed between said sections for raising and lowering said longitudinally movable section and for retaining the same in a variety of vertically adjustedpositions, the other of said sections: having brackets extending rearwardly therefrom and spaced widely apart throughout the-length of said post and means for attachment to a vertical wall adjacent one end of said tub for: connection with said supporting brackets to maintain said post in a position declined from the vertical where the lower end of said post may be shifted to be superimposed above the bottom of one end of a tub and where the upper end of said post is disposed in close relation to the wall.
