Abstract
Abstract A shower head having concentric rings of orifices separated by annular walls having axial ends forming concentric valve seats, a valve disk overlying the valve seats, and a thrust member positioned to press against the center of the disk and cause the disk to assume a progressively increased convex configuration for sequential contact with the valve seats.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
127 words
A jet regulating shower head, comprising: a. a housing structure; b. an orifice member forming a front side of the housing structure and defining therewith a chamber, the orifice member being pierced by a plurality of jet orifice sets disposed in concentric relation and separated by a plurality of concentric valve seat walls facing into the chamber; c. a flexible membrane means supported at its periphery within the chamber and covering the orifice member, the membrane means having at least one entrance opening communicating with one set of orifices; d. and the flexing means for applying a force to the central portion of the membrane means to cause the membrane means to assume a variable contour for engagement or disengagement with the valve seat walls in sequence.
Claim 2
Dependent Claim
127 words
A jet regulating shower head, comprising: a. a housing structure; b. an orifice member forming a front side of the housing structure and defining therewith a chamber, the orifice member being pierced by a plurality of jet orifice sets disposed in concentric relation and separated by a plurality of concentric valve seat walls facing into the chamber; c. a flexible membrane means supported at its periphery within the chamber and covering the orifice member, the membrane means having at least one entrance opening communicating with one set of orifices; d. and the flexing means for applying a force to the central portion of the membrane means to cause the membrane means to assume a variable contour for engagement or disengagement with the valve seat walls in sequence.
Claim 3
Dependent Claim
50 words
A shower head as defined in claim 1, wherein: a. the membrane means includes a seal disk formed of an elastomeric material and a backing disk having spring properties and is biased for movement toward a position tending to clear the seal disk with respect to the valve seat wall.
Claim 4
Dependent Claim
37 words
A shower head as defined in claim 1, wherein: a. the flexing means includes a central stem carried by the membrane means and a screwthreaded drive means including a handle accessible from the exterior of the housing.
Claim 5
Dependent Claim
44 words
A shower head as defined in claim 1, wherein: a. the flexing means includes a thrust member disposed in bearing engagement with the center portion of the membrane means and a screwthreaded drive means including a handle accessible from the exterior of the housing.
Claim 6
Dependent Claim
119 words
A shower head, comprising: a. housing means defining a cylindrical chamber having an inlet and including an essentially rigid front wall having at least a central set of orifices and a peripheral set of orifices and an inwardly extending annular valve seat separating the sets of orifices; b. a flexible sealing membrane means secured by its periphery within the chamber in confronting relation in its central region and movable between a position clearing the valve seat whereby water received in the chamber flows from both sets of orifices and a position engaging the valve seat whereby water received in the chamber flows through the central set of orifices only; c. and means for effecting flexing of the membrane means.
Claim 7
Dependent Claim
119 words
A shower head, comprising: a. housing means defining a cylindrical chamber having an inlet and including an essentially rigid front wall having at least a central set of orifices and a peripheral set of orifices and an inwardly extending annular valve seat separating the sets of orifices; b. a flexible sealing membrane means secured by its periphery within the chamber in confronting relation in its central region and movable between a position clearing the valve seat whereby water received in the chamber flows from both sets of orifices and a position engaging the valve seat whereby water received in the chamber flows through the central set of orifices only; c. and means for effecting flexing of the membrane means.
Claim 8
Dependent Claim
65 words
A shower head as defined in claim 5, wherein: a. the membrane means includes a backing element, and a yieldable sealing ring engageable with the valve seat; b. the flexing means includes a stem integral with the backing element, screwthread means connecting the stem to the housing means, and an external handle for advancing and retracting the sealing ring with respect to the valve seat.
Claim 9
Dependent Claim
71 words
A shower head as defined in claim 5, wherein: a. the membrane means includes a backing element, and a yieldable sealing ring engageable with the valve seat; b. the flexing means includes a central tubular stem connected to a water supply and having an end sealingly engaging the membrane means to exclude water from the surrounding chamber, and externally accessible screwthread means for effecting relative movement of the stem and membrane.
