| (54) | Massaging shower with rotary head |
| (57) A massaging shower with a rotary head, consisting of a fixed component (1) and a
rotary component (6) which rotates within said fixed component by the reaction effect
generated by the flow of water through duct structures (9) and holes (7) provided
in the rotary component. Said shower provides deep cleaning of the skin and enables
a hydromassage to be obtained with a relaxing and blood circulation enhancing effect.

[0001] This invention relates to a rotary head shower of particular usefulness and with considerable advantages compared with showers of the known art.
[0002] The shower according to the invention provides deep cleaning of the skin, so completely removing its dead material. It also provides a rational hydromassage with a slimming, relaxing, anticellulitis and blood circulation enhancing effect. Finally, it has important therapeutic effects in physiotherapy applications such as for muscular pain etc.
[0003] Said shower is also of simple construction, can be manufactured and installed very economically and offers maximum functionality and reliability.
[0004] The shower according to the invention is composed of two components, namely a fixed component and a rotary component, and is characterised in that said fixed component constitutes a lateral housing and support for said rotary component, said rotary component rotating within said fixed component by the effect of the reaction generated by the flow of water through duct structures and holes provided in said rotary component, said holes being suitably inclined to the shower axis.
[0005] These and further characteristics and advantages of the shower according to the invention will be more apparent from the detailed description given hereinafter and from the relative figures which relate to a preferred embodiment of the invention and are given by way of non-limiting example.
Figure 1 is a longitudinal section through the shower showing its two fixed and rotary components;
Figure 2 shows the upper base of the shower with the duct structures and holes for water flow shown in dashed lines.
[0006] The fixed component consists of a cylindrical shank 1 and a widened cylindrical part 1′ fixed to the upper end of said shank 1.
[0007] The shank 1 is connected at its lower end to the water feed pipe by known connectors (not shown).
[0008] A bush 3 is inserted by pressure into the upper segment of the shank 1 to form a rigid system with said shank.
[0009] The widened cylindrical part 1′ carries in correspondence with its upper circular edge a ring of bristles 2 which can be used if desired for massaging and for removing the dead material from the skin during showering.
[0010] The rotary component consists of two elements 6 and 6′ which mate along their respective conical surfaces 10 and 10′ and cylindrical surfaces 11 and 11′.
[0012] Said cylindrical shank 8 rotates freely within the bush 3 with which it is kept rigid by a snap ring 5 and washer 4.
[0013] The surface 10 of the element 6 comprises three grooves 9 in the shape of a segment of a circumference and of semicircular cross-section.
[0015] Said grooves 9 and 9′ start from the top of the hole 8′ and each terminates at a hole 7 provided in the element 6.
[0016] The elements 6 and 6′ are mounted in an arrangement such that the grooves 9 lie exactly superimposed on the grooves 9′ so as to form complete duct structures which convey the water from the hole 8′ to the holes 7 from which the water emerges.
[0018] The holes 7 are parallel to the surface 11 and are inclined at 10°-40° to the vertical at the base of the element 6 and are positioned peripherally at the vertices of an equilateral triangle.
[0019] Said duct structures have a diameter of between 3 and 10 mm and said holes 7 have a diameter of between 1 and 5 mm.
[0020] In the described embodiment three of said holes 7 are provided, but they can vary in number preferably between two and ten. The number of grooves can also vary, preferably between 2 and 6.
[0023] The various elements of the shower according to the invention can be constructed of metal or of synthetic resin, or some elements can be of metal and other of synthetic resin. Example of suitable metals are stainless steel, chromium-plated steel and brass; examples of synthetic resins are PVC and polypropylene.
[0024] As is apparent from the description the water arriving from the supply main enters the hole 8′ at pressure, is distributed through the duct structures formed from the grooves 9 and 9′ and emerges through the holes 7. An effect is therefore created which causes the component formed from the elements 6 and 6′ to rotate.
[0025] The aforegoing description demonstrates that the shower according to the invention attains the specified objects and in particular the water jets emerging from the holes 7 are directed obliquely and rotate to allow perfect cleaning of the skin and a rational hydromassage with beneficial aesthetic and therapeutic effects.
