The body portion is structured to provide three separate flow channels that project different types of streams including an oblique stream causing rotation of the body portion and a generally helically projected pattern that provides a massaging action on the bather, the body portion being equipped with relatively movable members that provide a valving action for selecting the desired flow channel and resulting stream form projected.
5 Claims, 10 Drawing Figures SHOWER HEAD This application is a continuation-in-part of my copending application, Ser. No. 41,950, filed June I, 1970 now abandoned and entitled Selective Multi- Flow Shower Head.
The invention relates in general to shower heads such as used for bathing purposes and more particularly to a shower head which has a rotary body portion that is equipped with manipulatable means for varying the form of water streams projected from the head.
Conventional shower heads have generally provided for the projection of but one form of water stream and variances in the stream are usually caused by manipulation of the control valve between the shower head and pressurized source of water. The stream, in such cases, normally takes the form of a plurality of individual streams that are discharged through suitable orifices in the head.
Body surface massaging is frequently recommended for people with certain types of physical ailments and it frequently happens that the person requiring the therapeutic treatment is incapable of massaging the body area requiring the treatment and also financially unable to afford the costs of labor involved for securing treatment.
The streams projected from conventional shower heads have little or no therapeutic massaging value and the present invention is directed to providing an improved shower head which has manipulatable means for varying the form of water streams projected by the head and wherein one of the stream forms provides a massaging action having therapeutic value.
A general object of the invention is to provide an improved shower head. A particular object of the invention is to provide a shower head which is capable of projecting more than one form of water stream and including a helical form of water stream that provides a massaging action when contacting the bathers body. Another object of the invention is to provide an improved shower head that is capable of projecting a water stream having a therapeutic massaging action and which is nevertheless adjustable to provide more conventional stream forms that are moreadaptable for bathing purposes. Yet another object of the invention is to provide a shower head which is relatively inexpensive to manufacture and which can be used to provide a massaging action on the bather and selectively adjusted to project more conventional water stream forms for washing purposes.
The novel features which are believed to be characteristic of this invention are set forth with particularity in the appended claims.

Reference isnow made to the drawings and wherein the shower head is generally designated with the numeral l0 and shown as including a ball and socket-type fitting 11 and a body portion 12 that has an axis of symmetry 60. The fitting 11 provides universal movement of the body portion in a conical zone and is adapted for connection with. a pressurized source of water, as for example to a threaded water distribution pipe (not shown) of a conventional household water supply distribution system. The body portion 12 is mounted for rotation about its axis 60 on the fitting component 11 of the shower head.
The fitting 11 includes a ball element 13, a socket element 14, an annular washer 15 and a hollow flanged cylindrical bushing 16 that is used in retaining the body portion '12 on fitting 11. The fitting has opposite ends 17 and 18 and is structurally equipped to provide a water passageway 19 that extends between the opposite ends of the fitting. 1
The socket element 14 has an internally threaded end 23 that adapts the element for connection with the pressurized source of water. The other end 24 of the socket element is enlarged to provide the socket area for the ball component 13 of the fitting. The washer 15 provides a pressure seal between the periphery of the ball element and the adjacent internal wall at the socket end 24 of element 14 and has an opening 25 that permits passage of the water into and ultimately through the ball element to the body 11 of the shower head. i
The ball element 13 has a bore 20 that is enlarged at its discharge end so as to receive and accommodate the end of the bushing 16. This arrangement provides an internal shoulder 21 in the ball 13 and the bushing 16 is pressed fit snugly against the shoulder in the ball bore 20 in connecting the body portion 12 to the fitting 11. Bushing 16 has a hollow portion 26 that provides the discharge end of the fitting passageway 19 and the flange 27 of the bushing laps the cylindrical bushing element 29 of the body portion 12 in providing the rotatable connection between the fitting 11 and body portion 12 of the shower head 10.
The body portion 12 of the shower head includes a hollow casing 28, the cylindrical bushing 29 which is fixed to the casing 28, and a pair of members 30 and 31 that are relatively movable to adjust the form of stream which is projected from the shower head. The nozzle member 31 has certain recesses that will be subsequently referred to and is equipped with an annular orifice plate 32 which is provided with a plurality of holes or orifices 55 that provide one form of stream projection from the shower head. The nozzle member 31 is also equipped with a circular screen 33 and preformed water diverting member 34 that cooperate to provide an aeriated form of stream projection from the shower head.
The casing 28 has a converging end portion 37 which provides a reception chamber 38 for water discharged from the fitting 11 and this end portion 37 has an opening 39 in which the hollow cylindrical bushing 29 is pressed fit and mounted the rotation about the flange bushing component 16 of the fitting 11. The other end portion 40 of the casing is generally cylindrical and provides an internal area in which the water distribution member 30 and nozzle member 31 are housed.
The water-distribution member 30 is in the form of a flat disk and the cylindrical end portion 40 of the casing has an internal shoulder 41 against which the disk member 30 is seated in the assembled body portion. Here the end portion 40 of the casing has an internal protuberance 42 that fits in a matching notch 42a at the periphery of the disk member 30 so as to prevent rotational movement of the disk.
The nozzle member 31 is a cylindrical metal element that also fits in the cylindrical end portion 40 of the casing and in a manner such that the upstream face 47 of the nozzle is flush against the downstream face of the disk member 30. The members 30 and 31 are retained in the end portion 40 by means of a slit ring element 36 which fits in a circular groove 43 at the discharge end of the casing portion 40. Here the ring 36 laps and bears against the downstream face 48 of the nozzle member so as to maintain facial contact between members 30 and 31.
from the openings of the other sets in the arrangement depicted, and the openings of each set provide inlet ports or passages to separate water discharge channels in the nozzle member that can be selected for use by rotation of the nozzle to positions providing respectively different projected stream forms from the shower head.
One water discharge channel of the nozzle member is made up of three circumferentially spaced and generally inclined orifices 49 that extend between the faces 47 and 48 of the member 31. A second water discharge channel in the member is formed by an annular recess 50 in the downstream face 48 of the member and three circumferentially spaced inlet openings 52 in the upstream face 47 and which communicate with the recess 50. The annular recess 50 has an enlarged portion which provides an internal shoulder 51 in the nozzle member and which is adapted and arranged to accommodate the location of the annular orifice plate 32 within the recess. This orifice plate 32 is pressed fit in the recess of the nozzle member and is provided with" suitable fins 58 that may be finger manipulated from the exterior of the body to rotate the nozzle member 31 into the proper position for the stream form selected.
The third water discharge channel in the nozzle is formed by a centrally located circular recess 53 in the downstream face 48 and by three cooperating axially converging inclined inlet openings 54 in the upstream face 47 that communicate with the recess. 53. This recess 53 houses the preformed water diverting member 34 and the circular screen 33 is generally seen in FIGS. 5, 7 and 9. The diverting member 34 is made of resilient material in the embodiment shown and has an axially arranged protuberance 56 that fits in an appropriate hole 56a at the base of the recess. The member is equipped with a flat surface 57 which bears against the circular screen 33 in the recess. The screen 33 is maintained in place by a hollow cylindrical retaining ring 36 that is pressed fit in the recess in facial contact with and along the perimeter of the screen member.
As previously indicated, the members 30 and 31 are relatively movable so as to provide a valving action that permits the user to select the form of water stream desired. In the embodiment illustrated, the nozzle member 31 is rotatably movable with respect to member 30 about the axis 60by the finger manipulation of the fins 58 that are located in the nozzle recess 50.
The holes 44, 4S and 46 provide passages that are in communication with the reception chamber 38 and hence also with the passageway 19 of the ball and socket fitting 11. The sets of holes 44, 45 and 46 in the distribution member 30 serve as water passages to the respective discharge channels in the nozzle member 31. As seen in FIG. 3, the respective sets of holes 44, 45 and 46 are generally centered on concentric circles that are designated at 61, 62 and 63 and in an arrangement where each hole of the respective sets is angularly spaced apart, by an angle of from the other holes in its set and in a grouped arrangement where the holes of each group are offset from the body axis 60 and radially align and spaced apart from the holes of the other sets in the grouped arrangement.
As for the rotatably adjustable nozzle member 31, the inlet ends 59 of the inclined orifices 49, and the inlet openings 52 and 54 of the channels that includes recesses 50 and 53 are also generally centered on concentric circles, designated at 64, 65 and 66 in FIG. 4. This provides a working arrangement for the flow of water through the distribution disk 30 and into the channel selected by the user through rotation of member 31. In contrast to the grouped radially aligned arrangement used in the distribution disk, the inlet openings 59', 52 and 54 are angularly displaced in the grouped arrangement provided in the nozzle. Thus, the inlet opening 52 in the grouped arrangement provided in nozzle 31 are angularly displaced from the inlet ends of the inclined orifices 49 by the angle A, from the inlet openings 54 by the angle A, As will be apparent to those skilled in the art, this arrangement enables the user to rotate the nozzle member 31 about the axis 60 of the body to any one of three positions that enables the water in the chamber 38 to pass through both of the members 30 and 31 but nevertheless through only one of the three channels of flow provided in the nozzle member 31 depending on the position selected.
Reference is now made to FIGS. 1 through 5 and wherein the nozzle member 31 is shown at a first position that provides for the passage of the water through the inclined orifices 49. In this position the inlet ends 59 of the orifices 49 are in working alignment with the passages provided by the openings 44 of the first set of openings in the distribution disk 30. Under such circumstances, and by virtue of the angularly displaced arrangement of the inlet openings 52 and 54 in the grouped arrangement shown in FIG. 4, the passage of water through openings 45 and 46 into the distribution channels involving recesses 50 and 53 respectively is obstructed by the upstream surface 47 of the nozzle member.
In FIGS. 6 and 7 the nozzle member is depicted as being in a second position at which the openings 45 of the second set of openings in the distribution disk 30 are in working alignment with the inlet openings 52 of the distribution channel that involves the annular recess 50. Under these circumstances, the passage of water through the openings 44 and 46 into the orifices 49 and recess 53 is obstructed by the upstream surface 47 of the nozzle so that a generally cylindrical multistream flow of water is projected from the head through the openings 55 in the annular orifice plate 32.
Reference is now made to FIGS. 8 and 9 wherein the nozzle is shown in a third rotated position at which the axially converging openings 46 of the third set in the distribution disk 30 are in working alignment with the three openings 54 in the nozzle member 31. In this arrangement, the passage of water through openings 44 and 45 is obstructed by the upper surface 47 of the nozzle member and the flow of water is through the recess 53. As previously indicated, the recess 53 houses screen 33 and a preformed water diverting member 34. Member 34 has a centrally located circular flange 67 and as the water flows through the recess 53 a slight vacuum is created underneath the flange 67 that causes air to be sucked in through the screen and to become mixed with he water passing through the recess. This causes an air-water mixture to be projected from the screen 33 and provides an aeriated stream of water to be projected from the head as depicted generally in FIG. 8.
Reference is again made to the arrangement depicted in FIGS. 1 through 5. As best seen in FIG. 1, the orifices 49 in nozzle member 31 are obliquely arranged with respect to the body axis 60 so that as water passes through the orifices 49 reactive rotary motion is imparted to the body member 12 and which causes the body member to rotate about the axis 60 as in the direction indicated by arrow 68 in FIG. 1. This results in the projection from each orifice 49 of a substantially solid stream of water that takes on a generally helical pattern of flow from the head and provides a forceful massaging action on the body area of the user which is contacted by the stream.
As the orifices rotate they generally define a circle in the plane 69 of the downstream face 48 of nozzle member 31 and in practice, it has been found that the best massaging action is secured when the orifices 49 project the stream in a plane which is substantially perpendicular to the plane 69 of rotation of the orifices and substantially tangentially to the circle defined in the plane 69 during their rotation with the body portion and at an angle B to the plane 69 of rotation which is between 55 and While only certain preferred embodiments of this invention have been shown and described by way of illustration, many modifications will occur to those skilled in the art and it is, therefore, desired that it be understood that ii is intended herein to cover all such modifications as fall within the true spirit and scope of this invention.
