DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
This invention relates to a shower head with water supplied through a flexible hose. The shower head provides two different modes of spray that can be switched by operating two push buttons.
BACKGROUND OF THE INVENTION
Shower heads of the kind indicated are known; they are equipped with two push buttons by means of which the user can made a selection among two different spray modes: either a sprinkle jet provided through a plurality of holes or supply ducts or a subdivided or aerated jet provided by means of a jet breaker or a jet aerator. In the conventional forms, this switching action is achieved by means of a piston deviation valve with two positions, which can be moved into one of the two positions by pushing a push button that is directly connected to it and it can be moved into the other position by means of a valve lever. These shower heads work in an unexceptional manner, but the mechanism with which they are equipped has considerable height which does not permit the construction of shower heads with reduced height, such as are required by technological demands and current aesthetic requirements. Furthermore, the required ducts have a complex shape and are therefore difficult to make. Moreover, the operations involved in the assembly and disassembly of these shower heads are relatively complicated and, hence, assembly cannot practically be automated during the production phase. The shape of these shower heads is determined by the structure of their mechanisms so that only slight leeway is left to anyone who designs their outer configuration, especially for aesthetic purposes.
In view of the above, a first object of this invention is to provide shower heads which can be made in shapes with reduced height.
Another object of the invention is to provide shower heads in which the assembly and disassembly operations are considerably simplified.
Yet another object of the invention is to provide shower heads where the operating parts are capable of receiving exterior restraining elements that can be designed with a great degree of leeway.
Finally, another object of the invention is to provide shower heads whose industrial production will be relatively economical.
SUMMARY OF THE INVENTION
According to the invention, these objects are attained primarily by virtue of the fact that the shower head has a delimited supply space, two delivery members of different type, two pertinent communication passages between said supply space and the two delivery members, two separate intercept valves arranged so as to control each one of the two communication passages, each valve being connected to an operating push button, and a valve lever connected to said two valves in order to link them so as to perform displacements in the opposite direction.
Due to these features, when one of the operating push buttons is pressed to open or close one of the valves, and hence to supply or close off one of the two delivery members, the valve lever causes a shift in the direction opposite to the other valve, and hence the closing off or supply of the other delivery member thus achieving an overall effect corresponding to the effect that is known in connection with a deviation valve. The height dimension of this device is determined only by the height of the delivery members and by the height of a single intercept valve with its own push button. This is why the height can be kept within very small limits and thus reduced to a minimum.
Preferably, each intercept valve is a piston valve whose upper end constitutes the pertinent operating push button. This makes it possible to reduce to an absolute minimum the height dimension of the assembly made up of the intercept valves and the pertinent operating push buttons.
Preferably, the supply space is delimited by an upper support member through which extend operating push buttons and by a lower support member, displaying the closing seats for said intercept valves and supporting said delivery members. The valve lever is pivoted in between said upper and lower memb
