PORTABLE SHOWER HEAD SUMMARY OF THE INVENTION The present invention relates to a portable shower 5 head having both a steady spray discharge and a pulsating discharge.

One purpose of the invention is a shower head of the type described which is attached by a flexible conduit to a wall outlet so that it can be moved by the user during a shower.

Another purpose is a shower head of the type described in which the pulsating discharge is controlled by an oscillating plate which, in its rest position, is positioned off center from its supporting pivotal connection.

Another purpose is a shower head of the type described in which water is directed into the diverter chamber in a tangential or swirling manner.

Another purpose is a shower head having a reciprocally removable diverter member to control both a pulsating spray and a steady spray.

Another purpose is a shower head of the type described in which there is a space inside of the spray forming member which space receives a portion of the water flowing past the spray forming member to maintain the proper position of the spray forming member during water discharge.

Other purposes will appear in the ensuing specification, drawings and claims.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present invention is designed as a specific improvement on the structure shown in US. Pat. No. 3,734,410.

Looking particularly at FIGS. 1 and 2, a shower head indicated generally at 10 may have a handle 12 and an integral housing 14. The handle 12 may have a threaded adapter 16 for use in attaching the shower head to flexible conduit. The shower head shown and described herein is portable in that it may be held by the user and moved around to direct either one of the two spray discharges at various parts of the body. A control know 18 is used to vary the type of discharge as will appear hereinafter and is positioned on a shaft 20 illustrated in FIG. 3, which extends outwardly from the housing 14.

LII

Looking particularly at FIGS. 4 and 5, the handle section 12 of the shower head defines a water passage 22 which extends from the adapter 16 to the housing 14. Positioned within the housing is a diverter member indicated generally at 24 and which includes a piston 26 having an upwardly projecting stem 28 with a rack formed along one side thereof. A pinion 32, integral with shaft 20 is in engagement with the rack 30 and thus rotation of the control knob 18 is effective to reciprocally move piston 26. As particularly shown in FIG. 6 the shaft 20 may mount integral stops 34 and 35 which are positioned to bear against a housing portion 36 and thus limit movement of rack 30 and piston 26.

Formed within piston 26 is a chamber 38 and positioned within chamber 38 is an oscillating plate 40. A projection 42 integral with piston 26, extends down wardly, as shown in FIG. 4, toward plate to limit its movement within chamber 38. Piston 26 has a downwardly extending skirt 44 which cooperates with a retainer 66 to mount a spray head 46. Uniformly spaced slots or grooves 48 in the exterior of the spray head form a discharge path. The spray head may have an upwardly extending projection 50, the apex of which supports the oscillating plate 40. It is important that the center line of plate 40 indicated at 52, be slightly offset from the point of contact with projection 50 when the plate 40 is in the rest or inoperative position. Thus when water is admitted into chamber 38, it will cause the plate to oscillate and move back and forth on projection 50 within the chamber. If the center line 52 of plate 40 rest precisely on the apex of projection 50, water within the plate would not cause oscillation and the plate would remain in a stable position. By having the center line slightly offset, the flow of water will cause the plate to move back and forth within the chamber. The movement of the plate within the chamber causes a pulsating discharge through grooves 48.

FIG. 5 illustrates the position of piston 26 when the shower head is used to provide a pulsating discharge. There are a pair of piston inlet passages 54 which are in communication with a housing inlet 56. Inlet 56 in turn is in communication with water passage 22. The passages 54 are each in communication with an exterior annular groove 58 such that water at inlet 56 will be circumferentially passed to both passages 54 for subsequent flow into chamber 38. Passages 54 are not directed at the center of chamber 38, but instead are directed in a more tangential manner. Each of the passages 54 have a wall 60 which defines the direction of flow of the incoming water and the flow path will be somewhat tangential to the sides of chamber 38 and will create a swirling movement of water within the chamber. The swirling movement of water is effective to initiate the oscillating action of plate 40.

When piston 26 is in the position of FIG. 4 water flows from inlet 56 into an annular area 62 surrounding skirt 44. Positioned within this annular area is a spray forming member 64 held in position by retainer 66 depending from the bottom of piston skirt 44. Retainer 66 has an upwardly extending 'V-shaped ridge 68 which is positioned against the bottom of spray forming member 64. In the alternative, the ridge may be on the bottom of the spray forming member. The top or upper surface 70 of the spray forming member has a plurality of upwardly extending bumps 72 which seat against a lower surface 74 of the piston. 26. As clearly indicated in FIG. 4, there is an annular space 76 behind spray forming member 64 and water flows into this area through notches 78 formed in surface 74 of piston 26. Thus water in space 76, behind the spray forming member, assists in maintaining the spray forming member concentric with the piston and in the proper position to carefully define a spray discharge without extrusion leakage.

The outer surface of spray forming member 64 is formed by a plurality of uniformly spaced grooves or notches 80 which may be formed at varying angles to define a somewhat cone shaped spray. Such a construction is known in the art.

Piston 26 may have a pair of seal rings 82 and 84 positioned in appropriate grooves on the exterior of the piston, with the seal rings being in sealing engagement with a body member 86 forming a portion of the housing 14. Seal rings 82 and 84 are on opposite sides of piston water passages 54.

The housing 14 may include, in addition to the body member 86, a cover 88 which may have suitable indicia on its outer surface, with the cover being suitably attached to the housing 14, as shown at 90. A lower portion 92 of the housing may have an upwardly extending skirt 94 which seats the body 86 within the housing. The entire assembly may be suitably assembled by sonic welding or the like into an integral structure.

FIG. 9 shows a modified form of the invention in which oscillating plate 96 positioned within the chamber 38 of FIGS. 4 and may have a downwardly extending projection 98 similar to the projection 50. The upper surface 100 of spray head 102 may be substantially flat or plane. The pivotal mounting of the oscillating plate may be formed either by a projection on the spray head and a plane surface on the plate or the reverse. In either case it is important that, in the rest position, the point of contact of the projection, whether it be on the plate or on the spray head, be slightly radially offset from the center of its facing surface.

In operation, when the shower head is in the position of FIG. 4, water will flow from passage 22, through inlet 56 to spray former 64. Water will pass downwardly through the various slots or grooves 80 to form a spray discharge of generally conical configuration.

When the spray head is moved to the position of FIG. 5, through the described rack and pinion, the entire piston moves downwardly so that inlet 56 is now in register with circumferentially extending groove 58 which provides water for the generally tangentially directed water passages 54. Water will thus pass into chamber 38, causing plate 40 to oscillate on its pivotal mounting. The oscillation of plate 40 will provide a pulsating discharge through the grooves 48.

Whereas the preferred form of this invention has been shown and described herein, it should be understood that there may be many modifications, substitutions and alterations thereto.
