SHEEI103 PAIENIEU 1m 1 31975 SHEU 2 BF 3 BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to liquid applicators in the form of a spray handle at the end of an extensible hose to which a douche probe or a spray head may be removably attached thereto and, more particularly, to systems for selectively coupling the spray handle and hose to multiple sources of pressurized liquid.

2. Background of the Prior Art In the prior art, it is not unusual to connect a douche system to the usual house plumbing as evidenced by US. patents to Lazarus Nos. 2,828,761, 3,430,267 to Van Houten, 1,752,782 to Burton, 69,675 to Ingram, 535,967 to Viale, and 2,364,491 to Traidou. Also, certain of these patents, such as Lazarus, contemplates the use of either a spray or a syringe tip at the end of a discharge hose, while the patents to Lazarus, Burton and to DiPasquale US. Pat. No. 3,337,629 contemplate the addition of a medicament to the douche water, while Merkel US. Pat. No. 3,195,148 employs a pump for pressurizing water permitting a person remote from the liquid source to apply water under pressure in an applicator sense.

It is to this general field that the present invention is directed and constitutes an improvement over the references noted above. None of the references combine multiple sources of liquid under pressure in a system permitting, in a selective manner, the coupling of an applicator and the hose thereto, and in particular, by means in which the completion of a fluid circuit from a given supply such as that of a tank holding a douche liquid including a medicament also results in the energization of a pump for pressurizing that liquid to deliver the same to the applicator under pressure sufficient to insure proper operation of the douche system set up thereby.

SUMMARY OF THE INVENTION and related components may be attached to a cabinet door. Adjacent the tank is provided a rotatable valve assembly for-selectively coupling a flexible hose and applicator t'o the tank or to the hot and cold water pipes of the conventional basin faucet. A centrifugal pump associated with the tank outlet directs the medicated douche liquid from the storage tank via a rotary valve assembly. Manual rotation of the valve to connect the tank to the hose and applicator causes microswitch closure energizing the pump to deliver the medicated douche liquid under presssure through the hose to the applicator. The applicator terminates in either a re movable spray head or a removable douche probe depending upon the liquid being applied.

The valve, in an alternate form of the invention, may comprise a valve head with plural orifices selectively and changeable alignable with an outlet, and having ring seals. In addition, visual indicator means in the form ofa light or the like is provided to show pump operation.

Other and further 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 drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings inmore detail, a conventional bathroom sink such as 10 is in cabinet form and is provided with a counter top 12 having a large rectangular opening within the same within which is positioned the bowl or basin 14 and to the rear of which, and supported by the sink top 12, is a conventional hot and cold water faucet assembly 16. Assembly 16 includes a discharge faucet 18 and hot and cold control knobs to the left and right respectively at 20 and 22. The assembly 16 receives hot and cold water from separate sources through pipes (not shown). In this respect, the present invention is directed to providing hot and cold

liquid supply lines

24 and 26 respectively, in the form of copper tubes or pipes which do not interfere with the normal provision of hot and cold water at the faucet assembly 16 but are merely taps permitting hot and cold water under pressure to be delivered to the rotary valve assembly 28 which, as seen in FIG. 2, is mounted beneath the counter top 12 and supported with respect thereto by a number of brackets 30 of L- shpaed configuration, being screwed respectively to the underside of the counter top 12 as at 32 and to the exterior of the cylindrical valve casing 34 as at 36. The rotary valve assembly 28 as best seen in FIGS. 4 and 5, is oriented such that its axis is vertical, being bored at 38 and counterbored at 40. Within the counterbore 40, is positioned a cylindrical rotary valve 42, which is of a diameter slightly less than the diameter of counterbore 40. In turn, the rotary valve 42 is partially bored from its bottom end as at 44 and is provided with an in tersecting radial opening 46 of oval configuration intermediate its ends. The bore 44 within the rotary valve 42 is in alignment with the bore 38 of casing 34, bore 38 defining the discharge path for the rotary valve assembly 28. The cylindrical, rotary valve 42 has extending from its upper end, a valve operating shaft 48 which is fixedly coupled to the rotary valve 42 and extends through bore 50 of a threaded cap or seal 52 which is threaded to the casing 34 at the upper end of counterbore 40. Shaft 48 extends through and above the counter top 12 and terminates in a rotary valve handle 54 such that by rotating the handle 54, the rotary valve 42 rotates within casing 34. Casing 34 is further provided with

radial bores

56, 58 and 60 at circumferentially spaced positions which are further counterbored at 62, 64 and 66 respectively, the counterbores each holding a spring biased tubular seal 68 formed of neoprene or the like. Each seal is counterbored at its outboard end as at 70 to define shoulder 72 against which one end of coil spring 74 abuts, the other end of the spring being in contact with the shoulder formed between the bored and counterbored portion of the housing. In turn, the radial bores are each threaded to permit fluid connections to the rotary valve assembly from the hot and cold

water supply lines

24 and 26 respectively, for

bores

56 and 58.

An important part of the present invention resides in the liquid storage tank or container 76 which is mounted within the cylindrical opening 78 of counter top 12, such that the upper end of the tank or container 76 protrudes above the counter top 12, being supported by rim 80 and permitting a cover 82 to be removed to add to the liquid contents 84 of the container.

Preferably, the container or storage tank 76 carries liquid 84 in the form of a medicated douche or the like. Bolted to the bottom of the storage tank or container 76 is a centrifugal pump 86 of conventional construction and constituting in general an electrical motor 90 mounted via brackets 92 and screws 94 to the bottom of tank 76 and terminating in a housing 96 within which rotates an impeller 98 mounted to the end of the motor drive shaft 160, the chamber defined by the casing 96 being open to the storage tank 76 at its center as at 102 and permitting the discharge of liquid 84 from the tank through passage 102 to a treatment liquid line or pipe 104 which is threadably coupled in turn to housing 34 of the rotary valve assembly 28 at radial bore 60. A manually operated shut off valve 106 may be provided within line 104 downstream of pump discharge passage 105 as desired.

Fixed to the rotary valve shaft 48, is a radial cam 108 as best seen in FIG. 3, and to the side of the radial cam 108 is fixed microswitch 110 via bracket 112 which is further coupled to the periphery of valve casing 34 such that switch actuator buttom 114 rides on the periphery of radial cam 108. Electrical line 116 connects microswitch 110 to the pump drive motor 90 and controls energization of the pump through a source (not shown).

Leading from axial bore 38 of valve casing 34, and being threadably coupled thereto, is an outlet pipe or line 118 to which is coupled a flexible hose 120, the opposite end of the hose being coupled to a hand held applicator indicated generally at 122. Applicator 122 comprises spray handle 124, privotable valve operator 126 carried thereby and operating. internally. a discharge valve (not shown). Applicator 122 terminates in FIG. 2, in a removable spray head 128 of conventional type which may be threadably coupled to the discharge end of spray handle 124. As further indicated in FIG. 6, spray head 128 may be replaced by douche probe 130, for instance, consisting of a hollow tubular member 130 terminating in an oval looped head 132 carrying multiple discharge outlets or openings 134 and having at its opposite end a threaded connection 136 permitting it to be sealably and threadably coupled to the discharge end of the spray handle 124. As evidenced in FIG. 1, the control handle 54 may be provided with indicia 140 which is associated with a fixed indicia on the upper surface of counter top 12, such that rotation of the valve to align certain of the indicia on the handle with the fixed indicia (not shown) on the counter top, indicates the position of the valve and also readily indicates the condition of microswitch operated by radial cam 108 carried by the same shaft 48.

The counter top 12 is further provided with a circular opening 138 which is smaller in diameter than that of the spray handle 124 but larger than that of hose such that the spray handle 124 is readily partially seated therein but permits extraction of a portion of the hose 120 when the applicator is raised from counter top 12.

In operation and with the removable spray head 128 coupled to the applicator 122, the rotary handle 54 may be rotated to a position such that oval opening 46 of the rotary valve 42 is in axial alignment with a given radial bore of the valve casing 34, as for instance 56 permitting fluid coupling of the hot water line 24 to the applicator 122 and permit the user to spray various parts of the body with hot water such as employed when washing ones hair, for instance. Alternatively, the valve assembly 28 may be actuated by rotation of rotary valve handle 54 such that cold water is supplied to the applicator 122, or a combination, or as further desired, rotation of the valve handle 54 to the off position seals opening 46 from any one of the liquid supply inlets as shown in FIG. 5, for instance. In this case, the spring biased seals 68 closely abut the periphery of cylindrical valve member 42 and thus permitting the removable spray head 128 to be removed and replaced with the douche probe for instance as evidenced in FIG. 6 without leakage. With the douche probe 130 attached or any other similar device, the selection handle may then be readily turned to permit alignment of the radial opening 46 of the rotary valve 40 with bore 60, thus fluid coupling the storage tank or container 76 to applicator 122 permitting medicated douche liquid 84 for instance under pressure provided by pump 86 to be discharged through the multiple openings 134 of probe 130. Pressurization is automatically achieved since the radial cam 108 moves to the position shown in FIG. 3 to displace microswitch actuator 114 sufficient to close the circuit to the pump drive motor 90. Centrifugal pump 86 is of the nonloading type which runs without moving a liquid as would be the case, for instance when the shut off valve 106 is closed and the pump actuated. It is to be noted that within the rotary valve assembly 28, the spring loaded noeprene seals ride against the rotary valve 42 and the valve casing holding liquids in their proper area with the liquid pressure pushing the seals against the valve body and each spring pushing its seal against the rotor to prevent leaks. Further, the oval opening 46 is designed so that it will not tear the tubular neoprene seals 68 as it turns past the seals, and further. the opening 46 is designed such that it will span the openings in the two seals aligncdwith bores 56 and 58 permitting the control of water temperature at applicator 122 by permitting both cold and hot water to be mixed and discharged through hose 120.

F168. 7 through discloses modifications ofthe invention as to valve structure and mounting assembly. Referring to FIG. 9, the cabinet structure for the sink includes an opening frame to which is connected a door 102 secured to the frame by hinges 104. A horizontal shelf 106'projects from the inner surface of the door and supports a tank 76a with a pump 86a thereon.

The pump is energized via an electrical line 108, and

a line 110 extends to a light bulb or other indicator 112 on the shelf to denote operation of the unit and to complete the operational circuit as indicated below. Hot and cold water sources 114,116 extend into the frame, and have flexible tubes 118,120, respectively, operatively secured thereon. An outlet conduit 122 for materials stored in the tank has a flexible tube 124 thereon and extends from the pump.

A modified form of mixing valve 28a is shown in FIGS. 7-10. The valve 28a comprises a body portion 126 having a reduced, externally threaded upper end 128. A bore 130 is formed in the body portion to serve as a main valve chamber, and a co-axial outlet 132 extends therefrom to the lower end 134 of the body. A cap 136 is threadably engaged on the upper end 128, said cap having a vertical opening 138 formed therein. An actuating rod 140 extends through the opening to a control handle 142 located above the shelf 106. The rod 140'carries a cam surface switch 144 to contact a switch 146 of the wire 110 resulting in actuation of the pump and in actuation of the light indicator 112 when the handle 142 is moved to pump operating position to dispense material from the tank. Suitable indicia indicating hot, cold or tank material application is provided adjacent the handle 142 on the shelf. The valve hasclosely spaced inlet openings for hot or cold water with

fittings

148, 150 to which are connected the conduits 118,120, respectively. An opening for material from the tank 86a has a fitting 152 to which the line 124 is connected.

A valve member 154 is rotatably seated in the bore 130 and comprises a substantially cyclindrical member fixedly secured to the rod 140 for movement therewith. Upper and lower seals 156,158, and an intermediate angular seal extend about the member, the seals being of rubber, neoprene or similar material. The member has a lateral inlet bore 162 which intersects a vertical discharge bore 164. Movement of the rod serves thus to provide for selective alignment of the bore 162 with either the hot or cold water inlets (or a combination of these) or alternatively with the inlet for the material from the tank.

The outlet 132 leads to a discharge hose 166 having a spray head 168 or other discharge device thereon, the latter being conveniently seated on the shelf 106.
