Description:
BACKGROUND OF THE INVENTION
1. Field of The Invention
This invention relates to a shower assembly for thorough cleansing of the human body and is particularly adapted for use in hospitals and similar institutions. The invention also finds utility in connection with public areas such as swimming pool entrances, service installations, schools and the like.
2. Statement of the Prior Art
It has heretofore been proposed that unitary shower assemblies be supplied, these assemblies being, in some instances, provided with self-contained water supply means. Such units are shown by way of example in the following prior U.S. Pat. Nos. 335,785, Taylor Feb. 9, 1886, 382,011, Smith May 1, 1888, 2,336,402, Kaiser Dec. 7, 1943, 2,659,899 Willis Nov. 24, l953, 2,702,390, Dillon Feb. 22, l955, and 3,l69,253, Segar Feb. l6, 1965.
SUMMARY OF THE INVENTION
The present invention provides an assembly of components which collectively function to thoroughly and hygienically bathe the human body with the requirement of only a minimum physical effort on the part of the bather. The principal objective of the invention resides in supplying a shower assembly in which the coactive relation of the components make up the assembly is such that the bather has only to enter an enclosure in order to be fully cleaned. This apparatus is of particular utility in caring for infirmed, disabled, handicapped and otherwise incapacitated individuals, but is of equal usefulness in performing other bathing functions.
The invention further prevents cross-contamination from one person to another, and is an improvement over immersion bathing of patients in that bath water often results in spread of an infection.
Another objective of the invention resides in the provision of a shower which need not be hand cleaned after each use.
If desired, disposable floor mats may be used with the shower.
The invention incorporates a unique pulsating water supply which effectively serves a cleansing and massage function. This pulsating effect is accomplished through the incorporation of a new and novel automatic valve system which alternatively constricts and then releases the water stream. Moreover, the apparatus is provided with means for the introduction of detergent, surfactant or disinfectant chemicals into the stream for intervals during operation.
The invention encompasses, without limitation, an arrangement of components including an entry ramp section affording privacy for disrobing, an automatic shower system, and a drying section provided with heated air drying means whereby the user is fully dried and may dress before leaving the ramp.
It is an important objective of this invention that a series of water inlet means, illustratively pipes, have a series of openings therein. Each of these openings is in the form of an aperture with diametric slots, the slots being disposed at variant angles with respect to successive ones thereof, thereby to provide sprays at differing angles. This maximizes the effective coverage area of the shower.
The water inlet means, in the form of pipes or carrying tubes, is designed such that no shower head or nozzle is used therewith. This results in reduced cost of manufacture, and also has the result that the system does not require increased water pressure in order to operate properly.
Additional objects and advantages of the invention will become apparent to those skilled in the art from a consideration of the following specification when read in conjunction with the annexed drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to the drawings in more detail, the apparatus comprising a preferred embodiment of the invention is therein generally identified by reference numeral 20. The assembly of components making up the device 20 includes a main ramp 22 of elongated form having an inclined entry section 24, and an exit section 26. The ramp is enclosed throughout its full extent at one side by an outer wall 28, and the wall has a hand rail 30 mounted on its interior surface. The opposite side of the ramp has a sidewall composed of sections 32 and 34 which are spaced from one another and provide an doorway 36 therebetween. The sections 32 and 34 have rails 36, 38 respectively. The ramp is supported from below by transverse cross members 40, and longitudinal members 42.
An enclosed bathing stall 44 comprises a floor 46, sidewalls 48, 50 and a back wall 52 having a drain hole 53 therein, connected to a pipe 55. The side and backwalls each have inwardly extending flanges 54, and stepped support members 56 are fixedly secured thereto as shown in FIG. 8. The wall sections 32 and 34, and the ramp floor adjacent the doorway 36 are also stepped, as at 56 in FIG. 5. The respective step portions support a horizontal, perforate grill member 58 in upwardly spaced relation to the floor 56, and the grill member provides a stand element for the bather or may support a special wheelchair device where required.
A main supply pipe 60, forming part of the water supply inlet means described below, extends into the staff 44 through an opening 62 in the sidewall 48. At a central location within the stall it is connected to a distributor 64 having a dished portion 66 in its top 68. The dished portion is centrally apertured at 70 and has cross slots 72 arranged diametrically to emit a vertical spray in the manner denoted in phantom lines in FIG. 9. Four branch pipes 74, 76, 78 and 80 extend from the chamber and have upstanding portions 82, 84, 86, 88, respectively, positioned at the corners of the stall 44. Each of the upstanding pipe portions has a closure 90 at its upper extremity, and each has a shutoff valve assembly 92 at its midsection.
The assembly 92, best shown in FIG. 6 of the drawings, comprises an elongated body 94 having a boss 96 at one side. A tapered opening 98 extends through the boss 96 and body 94, and a rotatable plug l00 is suitably configured for rotatable mounting therein. The plug l00 has a transverse bore 102 therein alignable with the pipe openings in one position, and also has a turning handle 104. Therefore, it is possible, through manipulation of the handle, to restrict or completely eliminate the flow of water through the valve. The effect of this is to permit a person who does not wish to direct a full force flow against the upper body to diminish that flow either throughout the shower or during the application of the cleansing agent, and also, where the occupant is confined to said special wheelchair, the upper section flow may be restricted completely.
An important feature of this invention relates to the means for emission of the spray from the upstanding pipe portions. As shown best in FIGS. 7 and 8 of the drawings, the pipes have a series of indentations 106 therein at regularly spaced intervals. As the approximate center of each indentation an aperture 108 is formed in the pipe, and a slot or diametric slot 110 is also formed to project from the aperture to the extent of the indentation. Each successive indentation in the pipe is formed in a manner such that its slit 110 is at an angle dissimilar to the angle of the next succeeding one thereof. Inasmuch as these slits direct the spray of water against the body of the bather, it will be understood that this different angularity results in maximum spray contact thereby insuring appropriate cleansing.
For those users having sufficient use of the arms to employ an overhead spray, or where an attendant is available to manipulate said spray, the supply pipe 60, exterior of the stall 44 has a T-joint 112 with an upstanding pipe 114. The pipe 114 connects with a manual valve 116 having handle 118 and a flexible hose 120 with a shower spray nozzle 122. The nozzle 122 has a hanger 124 on which it rests when not in use, and is optionally employed by the user of the shower by extending the flexible hose 120 over the top of the stall area. The attendant operates the valve 116 to activate or deactivate the spray from said nozzle.
Hot and cold water supply lines 126, 128 are connected at a fitting 130 to a pipe 132 leading to a second T-connection 134. The fitting 130 comprises a mixing assembly whereby a correct and comfortable water temperature is achieved. Mounted on the top branch of the T 134 is a dispensing container 136 for detergent or disinfectant compositions or the like. A manual control handle 138 is provided, and the attendant thereby controls the introduction of said composition into the shower water -- usually during the initial stages of the shower, or as required by circumstances.
An improved spray characteristic furnished by this invention, which eliminates the need for scrubbing and provides the other advantages heretofore mentioned, is occasioned by the new and novel surge valve 140 mounted in the water supply line. The valve 140 comprises a body 142 disposed between the pipe sections 144 and 146 connecting the T members 112 and 134. The body 142 has a central chamber with curvilinear distal and proximal walls 148, 150, and having step projections 152 adjacent the distal wall and indentations 154 at the corners of the proximal wall. A pivot rod 156 extends transversely across the chamber, and has a flap member thereon. This flap member includes a short projection 158 and a long projection 160. The rod is disposed adjacent the distal wall 148, and the projections alternatively occupy positions wherein they contact the walls at diametrically opposed projections and indentations 152, 154 thereof. In these positions, water flow through the valve is momentarily blocked, but pressure against the longer projection 160 causes opening of the valve and flow, and a reversal of the flap position. With this rapid alternative opening and closing of the valve, a pulsating spray is emitted through the pipe and nozzle openings.
The exit section 26 of the ramp has a plurality of openings 162 formed in the walls thereof, each covered by a screen 164. A combined fan and heater 166 is mounted exteriorally of the ramp to introduce dry, heated air through each of said openings. A roll 168 is also provided on this section, and supports another heated fan 170. Thus, the section 26 comprises a drying area which eliminates the need for towel drying of the bather.
In some instances, it is desirable that the drying chamber be associated directly with the bathing stall. It is, in such cases, necessary only to relocate the respective fans as, for example, by incorporating the side fans in the walls of the shower stall.
As will be understood from the foregoing, a bather may enter the device hereof and be fully bathed, substantially without the need for the services of an attendant, other than to manipulate the exterior valve means. Moreover, the shower operation is substantially complete, and affords infirmed persons with privacy and with sure cleansing of body areas.

The sections 32 and 34 have rails 36, 38 respectively. The ramp is supported from below by transverse cross members 40, and longitudinal members 42.
An enclosed bathing stall 44 comprises a floor 46, sidewalls 48, 50 and a back wall 52 having a drain hole 53 therein, connected to a pipe 55. The side and backwalls each have inwardly extending flanges 54, and stepped support members 56 are fixedly secured thereto as shown in FIG. 8. The wall sections 32 and 34, and the ramp floor adjacent the doorway 36 are also stepped, as at 56 in FIG. 5. The respective step portions support a horizontal, perforate grill member 58 in upwardly spaced relation to the floor 56, and the grill member provides a stand element for the bather or may support a special wheelchair device where required.
A main supply pipe 60, forming part of the water supply inlet means described below, extends into the staff 44 through an opening 62 in the sidewall 48.
