DETAILED DESCRIPTION Referring now to the drawings:
In the illustrated preferred embodiment, the invention comprises a bathtub, shown generally at 10, and including inner sidewalls 11 and 12, seen best in FIG. 5, outer sidewalls l3 and 14, inner end walls and 16, seen best in FIG. 3, and outer end walls 17 and 18.
Inner sidewall 11 is connected at its upper end to outer sidewall 13 by a shoulder 19 and together they form a back wall 20.
Lil
Likewise, inner end walls 15 and 16 are respectively connected to outer end walls 17 and 18 by shoulders 21 and 22. The walls 15 and 17 and shoulder 21 then comprise a head end wall 23 and the walls 16 and 18 and shoulder 22 form a foot end wall 24.
The top of inner sidewall 12 is connected to the top of outer sidewall 14 by a shoulder 25 that is wider than any of the other shoulders 19, 21 or 22, and the shoulder 25 thus provides a bench seat upon which a user can comfortably sit. The walls 12 and 14 and shoulder 25 together form a front wall 26. As shown, the inner end walls and inner sidewalls are interconnected by a bottom 27 and the walls, shoulders and bottom are formed as a single, integral piece. They can be formed of fiberglass, resins, stainless steel, porcelainized steel or of other suitable materials.
An exercise bar, shown generally at 32, extends over the tub. It includes two upright posts 33 and 34, respectively, extending upwardly from bases 33a and 34a mounted on the shoulders 25 and 19 by bolts 35.
Each post 33 and 34 has slots 36 and 37 (FIG. 8) extending upwardly for a portion of its length and at both sides the slots are enlarged at intervals therealong, asshown at 38, for purposes to be made apparent.
A T-clamp 39 is adapted to telescope around each of the posts 33 and 34 and the clamp includes an arcuate member 40 from which a socket 41 projects and another matching arcuate member 42.
The arcuate members are clamped tightly in a set position around the posts 33 and 34 by bolts 43 and interiorly threaded knobs 44 that screw onto the bolts. Holes 40a and 420 are provided through the members 40 and 42, respectively, to receive bolts 43 and a slot 42b extends from hole 42a to the lower edge of member 42.
Each bolt 43 includes a head 43a, a shoulder 43b, a central shank portion 43c, an enlarged midportion 43d having a collar 43e on the end nearest head 43a, and a threaded shank 43f. A washer 43g is curved to fit within the arcuate member 40 and has a hole therethrough such that it will fit over the enlarged midportion 43d, and a spring 45 is adapted to surround the enlarged midportion and to be positioned between collar 43e and washer 43g.
In use, shank portion 43c of a bolt 43 is moved through slot 42b to hole 42a of member 42, and also through slot 37. As the shank portion 43c is moved in slot 37 the threaded shank 43f is moved in slot 36 and the enlarged midportion 43d is within the post 33 or 34. Washer 43g fits against the inside of arcuate member 40, and spring 45 acts between the member 40 and collar 43a to bias the bolt until shank portions 432 and 430 are aligned so that the bolt will move vertically in slots 36 and 37.
The rod 47 is easily adjustable to any desired height. It is only necessary that the knobs 44 be loosened to allow the springs 45 to move the bolts 43 until the shank portions 43f and 43c are, respectively, lined up with slots 36 and 37, and to raise or lower the bar to a desired enlargement 38. Thereafter the knobs 44 are again tightened to pull the shoulders 43b and enlarged midportions 43d into the enlargements 38 of the slots 37 and 36, respectively.
The bottom of the tub is provided with a longitudinal groove 50 that slopes slightly downwardly from both ends to a drain The drain is conveniently positioned nearer to the head end wall than to the foot end wall so that the drain control can be conveniently positioned, as will be hereinafter described.
The bottom of the tub is also provided with transverse grooves 42, each of which extends from a sidewall to the longitudinal groove 50. Each transverse groove is inclined slightly so that water will drain from them to the groove 50, from where it will flow to the drain 5]. The transverse grooves form a roughened surface that provides better traction and reduces the possibility that a user of the tub will slip. In addition, they provide means whereby combination headrest-seat-step 53 can be positioned.
The headrest-seat-step comprises a generally U-shaped body adapted to extend across the interior of the tub, from sidewall to sidewall. The legs 53a and 53b, F IG. 3, of the body are spaced apart such that they will simultaneously fit into spaced ones of the transverse grooves 52, If desired, end walls, not shown, can be provided on the headrest-seat-step to strengthen it, but these must then terminate above the lowermost ends of the legs, so as not to interfere with positioning of the legs in the transverse grooves 52.
The top surface of the headrest-seat-step 53 has a central smooth portion 530 for use as a headrest and outer portions 53d that are provided with a rough surface so that a person can step or sit thereon without fear of slipping.
The grooves 52 serve a double purpose in providing a nonskid bottom surface for the tub and in providing means whereby the headrest-seat-step is held against sliding along the bottom of the tub.
A conventional, positive acting, drain plug 54, is positioned in a trap equipped discharge pipe 55, which is connected to drain 51, and the drain plug is operated, through a lever arm 56, FIG. 6, to which a control rod 57 is pivotally connected. The control rod extends upwardly through the shoulder and terminates in a handle 58. Lifting of handle 58 will raise the control rod and pivot the lever arm to close the drain valve and by pushing the handle down a user can move the control rod down and pivot the lever arm to open the drain.
An adjustable overflow assembly 59 also has a discharge pipe 60 that is connected into the pipe 55. The overflow assembly, FIG. 6, includes an intumed guide plate 61 at each side of a vertical slot 62 through the inner sidewall 12, and on one face of the sidewall similar pair of intumed guide plates 63, FIG. 6, similarly positioned with respect to slot 62, on the other face of wall 12.
A pair of plates 64 and 65 are then positioned to rest against the wall 12, on opposite sides thereof and to respectively vertically slide within the guide plates 61 and 63.
A conventional hydromassage unit, including a pump 73, FIG. 4, a motor 74 for driving the pump, a check valve 75 and an air injector 76, is located within the front wall 26.
A screened inlet 77, FIG. 3, is provided on the end of an intake pipe 78 that extends through the inner sidewall to the pump. The outlet of the pump is connected through a pipe system 79, including check valve 75 to the air injector 76. The air injector is of conventional construction and includes an eduction nozzle (not shown) that pulls air in through a screened inlet 80 at the top of a pipe 81 and that entrains it into the water being forced through the injector by the pump.
In operation, a user will fill the tub, to desired height, with water. This is done by operating a control valve 82 that is conveniently positioned inside of the tub and on the inner sidewall 12. Water to the valve is supplied through the usual hot and cold water lines 83 and 84, respectively. The water lines are connected to extend upwardly into the front wall, and there is no need for an access door such is conventionally provided through a structural wall to facilitate servicing of the plumbmg.
In the present instance the plumbing, as well as the controls and hydromassage unit, are all readily accessible, merely by removing the panels 28 and 29, as previously described.
When the desired water level has been achieved, the water can be turned off at valve 82 or it can be allowed to continuously fill the tub, in which case the overflow assembly will be set, as previously described, so that the desired water level will not be exceeded. Y
A user will then pull up on knob 85 to raise rod 86 and, through link 87 to actuate a switch 88. This starts motor 74 and drives pump 73. Water is pulled into the pump 73 at a location adjacent to foot end wall 14. It is filtered, air is added and it is ejected through a nozzle 89 back into the tub at a location adjacent to the head wall. The nozzle 89 is of conventional construction and is mounted to be universally turned so that the direction of spray can be set as desired.
The motor and pump are stopped merely by pressing down on knob 85.
With the present invention, a user can set his waterlevel in accordance with the position he desires to maintain in the tub, i.e. low 'for a supine or prone position, and higher if the user desires to sit on the bottom of the tub or on the headre'st-seatstep 53. The water level will remain constant even though fresh water is continually supplied from the inlet pipes.
The tub is safe to use and the exercise bar can be used to assist in entering or exiting the tub and can also be used in a physical conditioning or therapy program.
With the built in hydromassage unit in conjunction with the exercise bar, a complete hydrotherapy program can be undertaken.
All components are easily accessible. The tub can be used with its base resting on a floor in which case the side panels can be easily removed from above the floor level or it can be recessed into the floor where access through the panels can still be easily achieved from a room or area beneath the floor.
Although a preferred form of my invention has been herein disclosed, it is to be understood that the present disclosure is by way of example only and that variations are possible.
