SUMMARY OF THE INVENTION Handle-controlled sprays have been used heretofore in kitchens and bathrooms. Prior constructions have lacked appeal for use in bathrooms or as shower units either because of lack of a convenient control, inflexibility of adaptability to existing systems, tendency to leak from the spray head, or lack of simplicity, ease or reliability where control was attempted.

It is the purpose of this invention to provide a handlecontrolled spray that avoids the aforesaid problems and which provides spray flow therefrom upon exercise of simple and convenient squeeze-type pressure.

Another object of this invention is to provide a handle-controlled spray that is characterized by simplicity and inexpensiveness of construction, and by efficiency of operation.

A further object of this invention is to provide the combination of a handle-controlled spray with diverter valve and support accessories which facilitate the use of such a spray in shower-type facilities.

Further objects and advantages of this invention will become apparent as the following description proceeds and the features of novelty which characterize this invention will be pointed out with particularity in the claims annexed to and forming part of this specification.

A preferred embodiment of the invention is shown in the accompanying drawing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings, FIG. 1 illustrates aspray 10 that is being supported in a non-use position by a wall-mountedbracket 12 whose details are more fully disclosed in FIGS. 8-11. Thespray 10 is supplied by asupply hose 14 ofa length to permit desired operations and which connects at its upstream end to adiverter valve 16 whose details are shown in FIGS. 5-7.

In the installation of FIG. 1, water is supplied from an elevated wall-mounted type ofconduit 20 to one end of theelongated diverter valve 16. Atubular stud 22 extends from the other end ofdiverter valve 16 and supplies water to ashower head 24. Thesupply hose 14 connects to thediverter valve 16 intermediate its ends through a tubular stud 15 that extends transversely of the length of thevalve 16. The downstream end ofhose 14 connects to the upstream end ofspray 10. The downstream end ofspray 10 has aspray head 11 that is diametrically enlarged relative to the adjacent neck 10a ofspray 10, and whichhead 11 engages and is supported by spaced support fingers of a wall-mounted spray-support bracket 12.

Referring now to the spray whose features are shown in FIGS. 2-4, thesupply hose 14 is shown as being provided at its downstream end with an elongated tubular stud orshank 30 having on the outer periphery thereof a series of annular downstream facingbarbs 32. The downstream end ofhose 14 is clamped between the barbed portion of tubular stud and aferrule 34 in a manner well known in the art. An axiallyelongated nut 36 with a radially reducedportion 38 is arranged to be rotatably mounted on theshank 30. The upstream end ofnut 36 has an enlargedbore portion 40 that operates to shieldferrule 34. The downstream end of thenut 36 is provided with arecess 42 which receives or fits over a snap-ring 44 held in a groove 46 defined on thetubular stud 30. The nut is provided withexterior threads 48. The downstream end ofstud 30 has a reducedportion 50 to provide anupstream shoulder 52, and a sealingwasher 54 is positioned on reducedportion 50 againstshoulder 52. The terminal end ofstud 30 is flared at 56 for retaining the sealingwasher 54 in position.

Thenut 36 connects to a valve-mounting insert generally indicated at 60 which is provided with an upstreamannular portion 62 havingthreads 64 for cooperation withthreads 48 on the nut. A frusto-conical sealing surface 66 is provided facing generally upstream and against which the sealing washer 54 abuts. The insert 60 is provided with an outerannular abutment shoulder 68 and a downstreamannular portion 70 having defined therein an annular recess 72 into which is fitted an O-ring 74 for purposes of sealing. Thedownstream portion 70 has attachment thread 76 thereon for connection to the upstream end of the spray. The insert 60 thus defines aflow chamber 78 that is bounded at its downstream end by an annular web having an upstream facing valve seat 82 defined thereon with a central flow passageway 83 therethrough. Downstream of the web 80 there is an annular axially extendingflange 84 that surrounds theannular spring seat 86. The valve-mounting insert 60 carries avalve member 88 having a cup-shaped valve head 90 with a plurality of outwardly extendingspaced ribs 91 which limit thehead 90 from engaging the inner wall of the insert 60. Thevalve head 90 has an internally threadedcentral boss 92 andhead 90 carries an annular valve seal 94. An elongated assembly stem 96 is threaded inboss 92 and extends through flow passageway 83 into the interior of the spray member. The assembly stem 96 carries a seal-retainingflange 100 of smaller dimension than the flow passageway 83. A downstream portion of stem 96 has a cylindrical enlargement 102 that is grooved to receive and retain snap-ring 104. Ahelical spring 106 of frusto-conical shape is positioned between the snap-ring 104 and thespring seat 86, with thelargest loop 108 engagingseat 86 and theretainer flange 84, and the smallest loop 110 being centered on enlargement 102 and engagingsnapring 104. Downstream of the snap-ring 104 the stem has a cylindrical engagement stud 112 that terminates in a conical tip 1 14.

Thehollow spray body 116 is formed of plastic and has an upstream end internally threaded at 118. The downstream end of thespray body 116 is shaped to define a circular spray head 1].Spray head 11 has a central tubular threadedboss 120. There is also provided an annularcylindrical sealing surface 122. The spray-formingcylindrical surface 124 is provided downstream of sealingsurface 122. A plurality of spacingribs 126 extending generally radially of boss extend inwardly of the wall of the spray. A spray-formingface plate 128 is mounted by means ofbolt 130 having ahead 132 that sealingly engages the underside oftransverse wall 134 ofplate 128.Plate 128 has acylindrical wall 136 and a sealingsurface 138. The upstream side ofplate 128 has a circular rib 140 and the plurality of spray bores 142 are provided through theplate 128. There are many moreperipheral grooves 144 inwall 136 which cooperate withwall 124 in order to provide a circularly-arranged series of outer spray openings. A moldedseal member 146 of rubber or similar material and provided with agroove 148 for mounting on rib 140 is provided. Theseal member 146 carries outwardly biased sealinglips 150 and 152 which respectively are adapted to engage sealingsurfaces 122 and 138 in order to cut off drip of water after the flow of pressurized water has ceased. When the pressure of water is higher than the bias of the sealing lips, then the water is forced through the spray apertures to provide a series of concentric spray streams issuing from the spray head.

Provided on the handle at an attitude facing in the direction of thespray face 11, there is provided a handle recess generally indicated at 154 which is elongated axially of thespray body 116. Thehandle recess 154 is bounded by spacedlongitudinal flanges 156 and by an upstreamtransverse flange 158 and a downstreamtransverse flange 160. Within therecess 154 there is atubular stud 162 that is closer to theupstream flange 158. A headedplunger 164 is provided for movement through thetubular stud 162. Theplunger 164 has ashank 166 that is grooved to receive an O ring 168 that sealingly cooperates with the inner wall oftubular stud 162. The extended tip ofplunger 164 is threaded at 170 to cooperate with theguide block 172 shaped at its innermost end to provide asaddle recess 174 for receiving thereinto the extended end of 112 of the assembly stem 96.A'spring 174 is slip-fit overtubular stud 162 and is ofa length to engage thehead 178 of theplunger 164. Asqueeze control 180 is formed of sheet metal and shaped to provide spacedlongitudinal flanges 182 that lie closely adjacent and inwardly oflongitudinal flanges 156 of thehandle recess 154. Apivot pin 184 extends through thelongitudinal flanges 156 and thelongitudinal flanges 182 to provide for pivoting of thesqueeze control 180 about the axis ofpivot pin 184. Anabutment flange 186 at the upstream end of the squeeze control is provided for limiting pivoting of the squeeze control to the position seen in FIG. 3.

From what has been described, the operation of the device should be readily understandable. By squeezing thecontrol 180 inwardly, theplunger 164 is depressed tipping the valve stem 96 and its attachedvalve member 88, and the flow of water then passes through the spray handle for discharge from the nozzles defined at the downstream end of the spray. Because of the shape and arrangement of thecontrol 180, only squeeze pressure of the hand is required, as contrasted to finger or thumb pressure required by other controls. It has been found that such an arrangement is less fatiguing for a person using the spray. The flow of water and pressure therefrom depresses the sealinglips 150 and 152 and a full spray is achieved. Upon release of the squeeze control, the spring 176 and the pressure on the upstream side of thevalve member 88 operates to cut off flow because thevalve member 88 closes with the pressure of the incoming liquid and the tipping valve is restored from the flow position of FIG. 4 to the non-flow position as seen in FIG. 3. With flow cut off, the resilience oflips 150 and 152 restores them totheir normal sealing position so that there is no drip from the spray head. Thus the spray provides for precision control thereof.

Referring now to thediverter valve 16 whose details are illustrated in FIGS. 5-7, saiddiverter valve 16 has anelongated body 200 with a female threadedrecess 202 at its upstream end for connection toconduit 20. The opposite end ofbody 200 carries atubular stud 204 threaded for connection tostud 22. A transverse cylindrical bore 206 extends through thebody 200. Acontroller 208 is positioned in the transverse bore 206. The valve body defines anentry passageway 210 and there is a first outlet passageway 212 which leads tostud 204 and asecond outlet passageway 214 which leads to atransverse stud 216 which is adapted for connection to the upstream end ofsupply hose 14.

Controller 208 is of the shuttle type, whose terminal positions establish the selected operations, and has two spaced large diameter shaft portions 218a and 2l8b which are bounded at their respective outer ends byflanges 220a and 220b. The inner ends of shaft portions 218 each have agroove 222 for an O-ring seal 224. Between shaft portions 218 extends a reducedshaft 226 with an enlargedgrooved portion 218c centrally thereof carrying an O-ring seal 224. The annular spaces surrounding each section of reducedshaft 226 and positioned between spaced shaft portions provide transfer flow .chambers 228.

When the controller is in the FIG. 6 position, flow fromconduit 20 enters chamber 228a and is directed solely tooutlet passageway 214 which supplies water to thespray 10. When the controller is in the FIG. 7 position, flow passes to chamber 228k and through bothpassageway 214 and 212 to supply both the spray l0 and theshower head 24. Abutment offlanges 220a or 22% against the sides ofbody 200 operates to properly locate shaft portion 2180 to direct the liquid flow as desired.

Thesupport bracket 12 of FIGS. 8-11 includes anupright plate 240 formed with a rearwardly-extending, wall-engagingperipheral flange 242 and mountingapertures 244 for receiving countersunk wall-mounting screws. Extending forwardly ofplate 240 are spacedfingers 246 having upwardly-extendingretainer tips 248. The shape ofplate 240 and the adjacent ends offingers 246 cooperate to define an arcuate saddle, or recess, 250 between the fingers for accommodating the rounded handle portion ofspray 10 when thespray head 11 is seated onfingers 246 betweenplate 240 andretainer tips 248 as seen in FIG. 1.

In the shower attachment shown in FIG. 12, there is asupport bracket 260 for wall mounting with an outwardly extendingflange 262. Anadjustable sprayholder 264 is shown including aflange 266 arranged in facing relation toflange 262 and arranged for pivoting about the axis of shoulderedstem 268 of a finger-actuated, friction-type retainer whose head is indicated at 270. The remainder of spray-holder 264 includes asleeve 272 with anopen lateral segment 274, and an inner periphery that defines an enlargedupper recess 276 and a lower smaller recess 278. The open lateral segment is large enough to passsupply hose 14 therethrough. Theupper recess 276 will receive thespray handle 116 and thecontrol 180 when the latter is in the valve-open flow position of FIG. 4, and the lower recess 278 will receive therein the portion ofhandle 116 upstream oftransverse flange 158. Thus, when thespray 10 is in position onholder 264, thecontrol 180 is maintained depressed and a shower-like spray emanates fromhead 11, withadjustable holder 264 directing the attitude of the spray.

While there has been shown and described a particular embodiment of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention and, therefore, it is intended in the appended claims to cover all such changes and modifications as fall within the true spirit and scope of the invention.
