Definitions

  • the invention is directed to an apparatus for con ⁇ taining a liquid and, more particularly, to bathing apparatus having a sealable door through which invalid persons and others may pass and a prefillable reservoir with a valve mechanism for rapidly releasing liquid into the tub.
  • Simple containers for liquid and, more particularly, bathtubs are well known.
  • Special bathing tubs for invalid persons are also known.
  • a number of such tubs show various shapes and have a hinged door in a wall thereof. Some of such tubs include a platform for sitting. Some show the use of the tub for both soaking and showering.
  • Most such tubs are helpful only to partially disabled persons. That is, it is usually necessary that a person be able to step into the tub through the door and make the necessary movements inside the tub to situate himself for bathing ' .
  • most tubs have a standard spigot filling mechanism " which can result in a person sitting quite a long time in the tub and getting cold or can also result in too cold or too hot water contacting the person.
  • U. S. Patent 746,390 shows a tub providing a more rapid tub fill than usual by having a jacket about the tub for containing water for subsequent release into the tub.
  • the problem with a jacket reservoir is that it either cannot fill with a person in the tub or it cannot completely empty into the tub and, consequently, it is not unlikely that some of the water will eventually become dirty or contaminated. Also, such tub requires considerably more water in the reservoir than is ever available for use in the tub.
  • U. S. Patent 3,662,409 shows a tub more specifi ⁇ cally designed for wheel-chair constrained disabled persons. A door is openable exposing tracks for supporting the chair portion of a wheelchair.
  • a person in a wheelchair may-back up to the open door of the tub and push himself or have himself and the chair pushed off the carrier of the chair.
  • the door may be closed and the tub filled with water for bathing therein. After the water is drained from the tub and the door is opened, apparently the carrier is held in front of the door opening and the chair pulled onto the carrier.
  • the transition of the chair from either the tub or the chassis of the transfer unit to the other can be very frightening for a disabled person.
  • the present invention is directed to an apparatus for containing a liquid including a tub, a reservoir and a mechanism for supporting the reservoir elevated with respect to the tub.
  • the apparatus further includes a mechanism for filling the reservoir with liquid and mechanism for releasing the liquid in the reservoir to the tub.
  • the releasing mecha ⁇ nism includes other mechanism for distributing along one dimension the liquid released from the reservoir thereby to fall into the tub and create a waterfall appearance.
  • the apparatus further includes a tub drain.
  • Another embodiment has the supporting mechanism holding the reservoir above a portion of the tub on first and second support members on opposite sides of the tub. Additionally, the filling mechanism of such apparatus include ⁇ des mechanism for connecting the reservoir to a liquid source to allow movement of the supporting mechanism and the reser ⁇ voir thereon with respect to the tub thereby facilitating cleaning and repair to and behind the tub and the supporting mechanism.
  • the present invention has an embodiment for a bathing system including a tub with a door and mecha ⁇ nism for operating the door.
  • the system includes a wheeled transfer unit for moving an invalid person.
  • the transfer unit has a chair and a carrier for the chair.
  • the carrier includes mechanism for supporting the chair from outside the tub as the chair is moved through the door of the tub to the inside of the tub.
  • a further embodiment is directed to a bathing tub apparatus having a door and mechanism for operating the door.
  • the tub has an inner surface and outer walls along opposite sides.
  • the inner surface is shaped to include a raised por ⁇ tion for a person to sit thereon.
  • the outer walls have upper and lower portions.
  • the upper portions are inclined inwardly, while the lower portions include relief portions adjacent to the floor for a first person to easily stand with
  • the tub further includes mechanism for filling the tub and mechanism for draining the tub.
  • the present invention is directed to a method for cleansing a person including firstly the step of opening a door on a bathtub. Nextly, the person is moved through the open door and into the tub, such person being on a transfer unit including a chair and a carrier for the chair when the carrier supports the chair from outside the tub. Then, the method includes closing the door, bathing the person, opening the door and moving the person on the chair supported by the carrier from the tub.
  • Another method of the present invention is directed to ' installing bathing apparatus, which includes firstly con ⁇ necting an i placed drain system to a tub. Next, supporting mechanism for -a reservoir with the reservoir thereon is slid past a portion of the tub, said supporting mechanism having portions passing along opposite sides and the top of the tub. Then, water source means is connected to the reservoir. Finally, the supporting mechanism is slide past a further portion of the tub to a final installation location.
  • the present invention includes a reservoir separate from the tub.
  • the reservoir may be prefilled with a liquid, usually water, having a desired temperature.
  • the liquid may be rapidly dumped from the reservoir into the tub. All water is drained from the reservoir virtually eliminating any possibi ⁇ lity of contamination. Additionally, the rapid fill vastly reduces the likelihood of discomfort or chill to the person in the tub.
  • the reservoir may be refilled while the person is bathing so a second person may be bathed as soon as water drains when the first person has left or, if water becomes too soiled, it may be drained and the tub refilled rapidly to complete the bathing of the first person.
  • the tub of the present invention is further advan ⁇ tageous because of a hinged door at an end thereof.
  • the door may be swung away from the door opening to provide for easy access to the tub by a person stepping therein or by moving a person on the chair of a transfer unit through the opening to a location therein. With the door closed and sealed, as indicated, the reservoir may be rapidly dumped thereby pro ⁇ viding for quick filling of the tub to prevent the person * from getting cold or otherwise becoming or remaining uncom- fortable for an excessive period of time.
  • the reservoir is advantageously sup ⁇ ported 'by a cabinet unit' which may be slid past the tub thereby facilitating repair and cleaning in areas otherwise behind the support unit at one end of the tub.
  • Another advantage provides for a tub having upper walls inclined inwardly so that a helper can easily lean against the side walls and bath a person therein.
  • the tub has recesses along the lower portions adjacent to the floor so that the same person can easily locate his feet next to the tub.

  • Apparatus 20 includes generally a tub 22 and a support cabi ⁇ net 24. As shown in FIGURES 3 and 4, support cabinet 24 pro ⁇ vides support for a reservoir 26.
  • a liquid source plumbing system 28 provides for filling reservoir 26.
  • a dump valve 30 controls release of liquid within reservoir 26 to fall under gravity into tub 22.
  • Liquid, usually water, within tub 22 may be agitated by a circulating system 29 to provide cleansing and massaging action to the liquid. The liquid is drained from tub 22 through drain system 31 (see FIGURE 3).
  • Tub 22 includes a sealable door 32. On opening the door, a person may walk into or out of the tub or a person may be moved into or out of the tub using a transfer unit 34, as shown in FIGURE 5.
  • Tub 22 is made preferably- from a mold using fiberglass or similar materials.
  • tub 22 has a containing wall 36, as well as side walls 38 and 40 and an end frame 41 (see FIGURE 1) which cooperates with door 32.
  • containing wall 36 has a bi-level bottom surface. Lower surface 42 is a convenient distance beneath higher surface 44 so that a person may sit on higher surface 44 and comfortably have his feet on lower surface 42. It is noted that higher surface 44 could be slanted downwardly toward end 52 to be more comfortable for a sitting person. In either case, suface 44 preferably include ⁇ des a depressed portion for drainage to trough 62.
  • the door end of lower surface 42 forms a small step 46 up from surface 42 (see FIGURE 10) and has a portion 47 perpendicular to surface 42 and a portion 49 parallel to sur- face 42. Portion 47 provides support for door seal 48, and portion 49 provides support for a portion of U-shaped wall 50 of frame 41.
  • the other end 52 of containing wall 36 is
  • Containing wall 36 also includes sidewalls 54 which rise to the same height as end 52. Walls 54 mate at arcuate corners with lower and higher surfaces 42 and 44 and end 52.
  • a substantially horizontal flange 56 extends outwardly from side walls 54 and 52 and has a downwardly extending portion 58 at its outermost end.
  • Tub 22, as shown most clearly in FIGURE 8, further includes a pair of side shelves 60 to create a trough 62 therebetween with surface 42 forming the bottom of trough 62.
  • Shelves 60 are located toward door 32 from upper surface 44, but stop short of door 32 a sufficient distance to allow the necessary inward movement of door 32 as it moves from a sealed position to an open position explained in more detail hereinafter.
  • Shelves 60 are formed by side walls 54 extending arcuately inwardly before dropping to form substan ⁇ tially* vertical sides for trough 62.
  • Outer side walls 38 and 40 extend from frame 41 to the opposite end of tub 22.
  • Side walls 38 and 40 have an upper portion 64 and a lower portion 66.
  • Upper portion 64 is inclined inwardly as it rises, while lower portion 66 is inclined inwardly as it extends toward the floor.
  • Recesses 68 extend longitudinally from the door end of tub 22 to approximately midway along upper surface 44 within tub 22.
  • Containing wall 36 is attached to outer side walls 38 and 40 with screws or other known fastening mechanism 72 at a location where they meet near the top of tub 22. Additionally, containing wall 36 is supported and spaced apart from the side walls 38 and 40 by a plurality of sup- ports 74 spaced along the longitudinal length of tub 22. Each of supports 74 is appropriately shaped to provide the support required at the particular location where it is placed. Supports 74 are appropriately fastened in place.
  • Door frame 41 is shown most clearly in FIGURES 1 and 10.
  • Frame 41 provides a cap across the ends ' of containing wall 36 and side walls 38 and 40. Consequently, door frame 41 is substantially U-shaped with its base or face end con ⁇ forming with the shape of containing wall 36 at the door and with walls 38 and 40 along the sides.
  • the cross sectional shape at any particular location on frame 41 is generally U- shaped also, as shown in FIGURE 10.
  • a -support 74 extends between side wall 38 or 40 and containing wall 36.
  • Wall 50- of frame 41 is held in place by a plurality of screws 76 or other fastening mechanism.
  • Gasket 48 butts against step 46 and the inner end of wall 50 of frame 41 to form a seal bet ⁇ ween those surfaces and door 32 when door 32 is locked closed.
  • Door 32 spans across the end opening between inner side walls 54 as well as reaches from bottom 42 to a level approximately flush with flange 56.
  • Door 32 may be bowed outwardly as shown in FIGURES 1 and 3 or it may be flat or some other shape. In any case, it includes an outer surface 78 for contact with gasket 48 to provide a seal.
  • Hinge mechanism 80 functions to swing door 32 bet- ween open and closed positions as indicated in FIGURE 9. It is understood that for the general feature of a swingable door, mechanism 80 as shown is exemplary and other hinge mechanisms could provide that feature. A preferred embodi-
  • hinge 80 includes a vertically-extending U-shaped bracket 82 attached centrally to door 32 with the legs 84 of the bracket extending outwardly.
  • a side bracket 86 may be attached either to frame 41 or, as shown in FIGURE 1, to side wall 38. It is understood, of course, that bracket 86 could be attached to the other side of tub 22 at side wall 40 so as to provide a door swing in the opposite direction from that shown.
  • bracket 86 includes a U-shaped portion 88, similar to bracket 82 with legs 90 extending outwardly from the face of frame 41.
  • Smaller Ushaped, rotatable holders 92 are fastened with pivot pins 98 and 100 at the legs thereof to each of legs 90 and 84 of brackets 86 and 82. Near the ends of the bases of holders 92, parallel upper and lower rods 94 and 96 are pivotably attached. Such a con ⁇ figuration, provides for a parallelogram movement of rods 94 and 96. Thus, rods 94 and 96 pivot at the ends to lift door 32 as shown in FIGURE 9. Also, holders 92 pivot about pivot pins 98 and 100, as shown in FIGURE 7, so that door 32 may move from the inside of the tub to the outside.
  • Door 32 is aided in its upward movement by a pneumatic piston and cylinder assembly 104 attached between the lower, side pivot 106 of rod 96 and the upper, center pivot 108 of rod 94.

  • Lock mechanism 114 forces door 32 into a sealing relationship with gasket 48.
  • Lock mechanism 114 includes a member 116 rotatable about attachment 112.
  • Member 116 is preferably a flat, rectangular item of metal extending from about midway on frame 41 near side wall 40 to about midway along rod 96.
  • a receiver element 118 is attached to frame 41 and has a notch therein.
  • the other end of member 116 has a stop 120 extending inwardly from the lower edge of member 116 to contact rod 96 thereby preventing member 116 from rotating any farther.
  • Member 116 should be somewhat springy so that as it rotates to be parallel with rod 96, member 116 may slide over the upper side of receiver 118 and snap into the notch. At the same time, stop 120 contacts rod 96.
  • extension 121 extends inwardly from member 116 adjacent to the outer side of receiver 118 to hold tub 22 from springing outwardly when it is filled with liquid. Handles 122 on member 116 facilitate movement of member 116.
  • door 32 opens with a somewhat complex set of movements.
  • Member 116 is first rotated clockwise.
  • pneumatic assembly 104 forces door 32 upwardly causing arms 94 and 96 to pivot at their ends and move in a parallelogram fashion to dotted position of FIGURE 9.

Loop 206 encircles stem 180 near stop 182, while loop 208 encircles vertical portion 194 of L-member 190. Loop 208 and loop 196 simply function to guide movement of connecting member 198.
  • control lever 158 is moved to an open position, the bellcrank moves connect member 198 upwardly so that loop 182 engages stop 204 and pulls buoyant plug 160 from opening 150 thereby allowing liquid to exit.
  • control lever 158 If it is desired to stop liquid from draining before all the liquid has drained, control lever 158 is moved to an off position whereby the internal portion 178 of the bellcrank moves con ⁇ nect member 198 downwardly so that loop 202 contacts the top of plug 160 and forces it downwardly into the flow of liquid leaving opening 150. As plug 160 moves into the flow, it becomes entrained and is forced rapidly into a plugging posi ⁇ tion in opening 150.
  • Spring 210 is compressed by loop 208 against a washer on horizontal portion 192 when connect member 198 is moved downwardly. Therefore, when control lever 158 is released, spring 210 forces connect member 198 upwardly so that through* the rest of the linkage control lever 158 is returned to its neutral position.
  • plug 160 will drop into opening 150 by the force of its weight. Similarly, the weight of connect member 198 brings control lever 158 back to a neutral position.

Abstract

Baignoire destinée principalement à des personnes invalides. L'installation comprend une baignoire (22) munie d'une porte fermant de manière étanche (32), qu'une personne peut traverser en marchant ou en étant transportée sur une unité de transfert. L'installation comprend en outre un réservoir remplissable au préalable (26) disposé au-dessus de la baignoire. Le liquide peut être libéré rapidement pour s'écouler du réservoir dans la baignoire et remplir rapidement cette dernière, afin d'empêcher que la personne ne prenne froid. Le réservoir peut être ensuite rempli de liquide préchauffé pendant que la personne prend son bain. Le réservoir (26) est maintenu par une unité de support (24) qui sert de cabinet de stockage et d'étagère et qui peut se déplacer longitudinalement par rapport à la baignoire (22) pour permettre le nettoyage et les réparations derrière la baignoire. Cette dernière (22) comprend un système de circulation de liquide servant à agiter le liquide pour en améliorer les effets thérapeutiques et de nettoyage. Une douche manuelle (224) peut être également utilisée par la personne dans la baignoire.
