Abstract
A shower head generally comprising a backing plate, a diaphragm and a cover plate. The rear surface of the backing plate includes a receptacle for receiving a conduit through which pressurized water may be directed to an aperture extending through the backing plate. The front surface of the diaphragm has a plurality of nipples extending outwardly therefrom with each nipple having longitudinal bore extending therethrough. The cover plate has a plurality of holes extending therethrough for receiving the nipples on the diaphragm such that the cover holds the diaphragm against the front surface of the backing plate. Pressurized water delivered through the aperture causes an outward deflection of the diaphragm away from the backing plate allowing water to be expelled through the bores in the nipples.
Claims15
A shower head comprising:
- (i) a backing plate having a relatively flat and smooth front surface and a rear surface, said rear surface including a receptacle for receiving a conduit through which pressurized water may be directed, said backing plate further including an aperture passing therethrough permitting water to flow from said receptacle through said aperture to said front surface;
- (ii) a diaphragm receivable over said front surface of said backing plate, said diaphragm having a front and a rear surface, said front surface having a plurality of nipples extending outwardly therefrom, said nipples having longitudinal bores extending therethrough connecting said front and rear surfaces of said diaphragm;
- and,
- (iii) a cover plate releasably securable to said backing plate, said cover plate having a plurality of holes extending therethrough for receiving said nipples on said diaphragm, when said diaphragm received over said front surface of said backing plate said cover plate releasably securable to said backing plate holding said diaphragm against said front surface of said backing plate with said nipples extending through said holes in said cover plate such that the delivery of pressurized water through said aperture in said backing plate causes an outward deflection of said diaphragm away from said backing plate, said pressurized water flowing between said backing plate and said diaphragm and expelled through said longitudinal bores in said nipples.
An improved shower head comprising
- (i) a backing plate having a relatively flat and smooth front surface and a rear surface that includes a receptacle for receiving a conduit through which pressurized water may be delivered, said backing plate further including an aperture passing from said receptacle to said front surface;
- (ii) a diaphragm having a perimeter dimensioned so as to be receivable over said front surface of said backing plate, said diaphragm having a front surface that includes a plurality of nipples extending outwardly therefrom, each of said nipples having longitudinal bores extending therethrough connecting said front surface of said diaphragm with said rear surface of said diaphragm;
- and,
- (iii) a cover plate releasably securable to said backing plate, said cover plate having a plurality of holes extending therethrough and arranged in a pattern to match the pattern of said nipples extending outwardly from said front surface of said diaphragm such that when said diaphragm is received over said front surface of said backing plate with said cover plate releasably secured to said backing plate and said diaphragm received and held between said cover plate and said front surface of said backing plate said nipples extending through said holes in said cover plate, upon the delivery of pressurized water through said aperture in said backing plate said diaphragm deflecting outwardly from said backing plate to permit water to flow between said backing plate and said diaphragm to said nipples, where the supply of pressurized water through said aperture is reduced below a predetermined level said diaphragm flexing backwardly from its deflected position and into contact with said front surface of said backing plate thereby stopping the flow of water through said nipples.
