Abstract

A shower head with a spray plate mounted on the housing has water passage openings and a further plate made of elastic material which has openings coaxial to the water passage openings. The further plate is fitted over the outside of the spray plate which presses against it. Nozzle projections with exit openings are formed coaxial with respect to the openings which have a smaller diameter than the water passage openings.

Claims

1. A shower head comprising:

a shower head housing connectable to a source of water;

a spray plate in said housing having a multiplicity of water passage openings for discharging respective streams of water from said housing; and

a further plate in said housing lying against said spray plate, formed of an elastic material, defining an outer face of said shower head, and provided with a multiplicity of laterally deflectable unconfined nozzles projecting freely outwardly from said face, and free to deflect laterally at junctions of said nozzles with said plates, each of said nozzles being coaxially aligned with a respective one of said openings for producing a respective jet of water, said nozzles having exit orifices which are smaller than said water passage openings, lateral deflection of said nozzles by a user breaking up calcification in said nozzles.

2. The shower head defined in claim 1 wherein each of said nozzles has an inner diameter greater than a wall thickness of the respective nozzle.

3. The shower head defined in claim 1 wherein each of said nozzles is constructed and arranged so that an inner diameter thereof expands under water pressure.
