Abstract
Abstract A shower spray head for providing a fluid spray with mechanical vibration of a part of the spray head, comprises, in combination, a fluid flow for delivering a shower spray; a turbine mounted in the path and drivable in rotation about an axis by fluid flow through the path; an eccentric rotatable form mounted for rotation about the axis and drivable by the turbine and eccentrically mounted with respect to the axis; and a vibratory housing connected by a pivotal connection to the eccentric form whereby rotation of the turbine during use causes vibration of the vibratory housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
139 words
A shower spray head for providing a fluid spray with mechanical vibration of a part of said head; said shower spray head comprising, in combination, means forming a path for fluid flow and for delivering a shower spray; a turbine member mounted in said path and drivable in rotation about an axis by fluid flow through said path; an eccentric member mounted for rotation about said axis and which is drivable by said turbine member and is eccentrically mounted with respect to said axis; and a vibratory member connected by a pivotal connexion to said eccentric member whereby rotation of said turbine member during use causes vibration of said vibratory member in one plane substantially at right angles to the turbine member axis of rotation and causes consequent vibration of said part of said head in said one plane.
Claim 2
Dependent Claim
139 words
A shower spray head for providing a fluid spray with mechanical vibration of a part of said head; said shower spray head comprising, in combination, means forming a path for fluid flow and for delivering a shower spray; a turbine member mounted in said path and drivable in rotation about an axis by fluid flow through said path; an eccentric member mounted for rotation about said axis and which is drivable by said turbine member and is eccentrically mounted with respect to said axis; and a vibratory member connected by a pivotal connexion to said eccentric member whereby rotation of said turbine member during use causes vibration of said vibratory member in one plane substantially at right angles to the turbine member axis of rotation and causes consequent vibration of said part of said head in said one plane.
Claim 3
Dependent Claim
38 words
A shower spray head according to claim 1, wherein said eccentric member is in the form of an eccentric cam and said vibratory member has an aperture therein with said aperture pivotally located about said cam with play.
Claim 4
Dependent Claim
43 words
A shower spray head according to claim 2, wherein said cam is an elliptical formation integral with said turbine member and disposed eccentrically about said axis, and said aperture in said vibratory member is a circular aperture located with play about said formation.
Claim 5
Dependent Claim
77 words
A shower spray head according to claim 1, wherein said eccentric member is in the form of an eccentric cam and said vibratory member is pivotally connected to said cam by an arm having one end pivotally connected to said cam, and the other end of said arm being connected to said vibratory member, said vibratory member being mounted for reciprocating motion about an axis which is spaced from said axis of rotation of said turbine member.
Claim 6
Dependent Claim
23 words
A shower spray head according to claim 1, wherein said vibratory member comprises a portion of a housing of said shower spray head.
Claim 7
Dependent Claim
62 words
A shower spray head according to claim 1, having means forming two alternative flow paths, a first alternative flow path including pulsation means for cyclic interruption of the fluid flow along it, for providing a pulsating spray, and a second alternative flow path for producing a non-pulsating spray, and control means manually operable to distribute the flow adjustably amongst the flow paths.
Claim 8
Dependent Claim
18 words
A shower spray head according to claim 1, wherein a massage brush is mounted on said vibratory member.
