Abstract
Abstract Hand showers of different functions all have the same casing, which comprises solely channels of non-specific function and non-specific connection means for carrying water. A first inner insert comprises complementary, non-specific connection means, by which a connection to the casing for the water is provided as well as channels of exclusively large area carrying water and which now have a specific function. Finally, all the channels carrying water, which possibly tend to become blocked on account of their small cross section, and all other parts possibly requiring maintenance are combined in an outer insert of specific function, into which the water flows from the inner insert.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
191 words
A handshower set which is capable of carrying out a plurality of different fluid spray patterns and functions, which set comprises (a) single casing that includes a handle integrally connected to a bell-shaped end part and which is provided with an interior water supply channel. (b) a plurality of different intermediate inserts that are engageable with the bell-shaped end part of said single casing and which are constructed to receive the flow of water from said casing and to thereafter provide an intermediate modification of the direction of flow of that water through the bell shaped end part, and (c) a plurality of different outer inserts that are engageable with said intermediate inserts and which are constructed to receive the flow of water from said intermediate inserts and to thereafter finally modify the flow of water exiting from the handshower, whereby (1) by appropriate selection of the intermediate insert and the outer insert for engagement with each other and with said casing, one may obtain any one of a plurality of different types of fluid flow from the handshower, and (2) maintenance, repair and replacement are facilitated and made more economical.

A handshower set which is capable of carrying out a plurality of different fluid spray patterns and functions, which set comprises (a) single casing that includes a handle integrally connected to a bell-shaped end part and which is provided with an interior water supply channel. (b) a plurality of different intermediate inserts that are engageable with the bell-shaped end part of said single casing and which are constructed to receive the flow of water from said casing and to thereafter provide an intermediate modification of the direction of flow of that water through the bell shaped end part, and (c) a plurality of different outer inserts that are engageable with said intermediate inserts and which are constructed to receive the flow of water from said intermediate inserts and to thereafter finally modify the flow of water exiting from the handshower, whereby (1) by appropriate selection of the intermediate insert and the outer insert for engagement with each other and with said casing, one may obtain any one of a plurality of different types of fluid flow from the handshower, and (2) maintenance, repair and replacement are facilitated and made more economical.
Claim 3
Dependent Claim
230 words
An assemblage of components for producing a variety of different handshower units that have a variety of different fluid spray patterns, each assembled hand shower unit consisting of only three parts that fit together to define the channels through which water will flow, the three essential combineable components being selected from one of each of the following three categories. (a) a single casing that includes a handle integrally connected to a bell-shaped end part and which is provided with an interior water supply channel, (b) a plurality of different intermediate inserts that are engageable with the bell-shaped end part of said single casing and which are constructed to receive the flow of water from said casing and to thereafter provide an intermediate modification of the direction of flow of that water through the bell shaped end port, and (c) a plurality of different outer inserts that are engageable with said intermediate inserts and which are constructed to receive the flow of water from said intermediate inserts and to thereafter finally modify the flow of water exciting from the handshower whereby (1) by appropriate selection of the intermediate insert and the outer insert for engagement with each other and with said casing, one may obtain any one of a plurality of different types of fluid flow from the handshower, and (2) maintenance, repair and replacement are facilitated and made more economical.
