In keeping with these objects and with others which will become apparent hereinafter, one feature of the present invention resides, briefly stated in a water shower system, which has an overhead shower; a hand-held shower; a water distributing element connected to a source of water and also to said overhead shower and to said hand-held shower and having a valve located between the source of water and overhead shower and said hand-held shower; and a switch located outside of said water distributing element with said valve and spaced from said water distributing element with said valve, operatable by a user and having a first position in which said valve provides a water supply to said hand-held shower so that water issues from said hand-held shower, and a second position in which said valve provides a water supply to said overhead shower so that water issues from said overhead shower.
When the water supply system is designed in accordance with the present invention, the switch can be located in the area of the hand-held shower, so that a user can operate the system and provide a desired water supply with the switch located at a low height, and it is no longer necessary to reach locations high above the user's head. As a result, the new system is very convenient in operation, especially for elderly people, disabled people sitting in wheelchairs, short people, etc. At the same time it provides various modes of operation as desired by a user.
In accordance with another feature of the present invention, said hand-held shower has a showerhead with a handle and a hose connecting said handle with said water distributing element, and wherein said switch can be located on said handle, or on said hose, or on a connecting member which connects said handle to said hose.
Still another feature of the present invention is that in the water shower system of the invention said overhead shower and said hand-held shower each have a showerhead, and wherein each of said showerheads of said different showers has at least two groups of openings providing issuance of water in at least two different patterns.
A further new feature of the present invention is that in the inventive water shower system said water distributing element has an inlet channel, a first outlet channel connected with said hand-held shower, and a second outlet channel connected with said overhead shower, said valve is located between said inlet channel and said outlet channels, and said inlet channel and said second outlet channel are coaxial with one another along an axis, while said first outlet channel extends substantially perpendicular to said axis.
In the water shower system said valve has a valve member moveable perpendicular to said axis. Also a restriction is provided between said inlet channel and said moveable valve member and restricting a water flow.
Still a further feature of the present invention is that said switch has a third position in which it is not fully closed, so that said valve provides issuance of water in a pulsating manner.
The novel features of the invention are set forth in particular in the appended claims. The invention itself, however, will be best understood from the following description of the preferred embodiments, which is accompanied by the following drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
A water system in accordance with the present invention has a held-held shower 1 which includes a hand-held showerhead 2, a handle 3, and a hose 4 connected to the handle by a connecting member 6 and connectable to a water source 5, formed for example as a water pipe. The water supply system also has a switch 7 which is associated with the hand-held shower 1.
The water system further has an overhead shower with an overhead showerhead 8, and a valve 9 associated with a water distributing element 10. The valve 9 is located between the water source 5 and the hand-held shower 1. The hand-held shower and the overhead shower are connected with the water source 5 via the water distributing element 10. The switch 7 is located outside the water distributing element 10 and spaced away from the water distributing element 10 and the valve 9.
The water distributing element 10 has a housing 11 provided with channels including an inlet channel 12, a first outlet channel 13 and a second outlet channel 14 connected, for example by threads, to the water source 5, to the hand-held shower and to the overhead shower correspondingly. The inlet channel 12 is coaxial with the second outlet channel 14 connected to the overhead shower, along an axis, while the first outlet channel 13 connected to the hand-held shower extends substantially perpendicularly to this axis.
A restriction 15 is provided between the inlet channel 12 and a valve body of the valve 9 and restricts a water flow, and two washers 16 are arranged at its opposite sides. The valve 9 is located inside an intermediate space 17 of the housing 11 between the inlet channel 12 and the outlet channels 13 and 14. The valve has a body 18 with a valve element 19 having a V-shaped valve member 20 and a U-shaped valve member 21. The valve body has two grooves 22 with ring seals 23.
The valve body is cylindrical and its side walls 24 have four openings 25. In the upper area the valve body has a partition 26 with an opening 27 and four petals 28. The valve is fixed by a threaded bush 29 located in the outlet channel 13 and having an opening 30. Sealing rings 31 are provided for a leak-free water flow.
The switch 7 has at least two positions, including a first position which is an open position and a second position which is a closed position. The switch 7 can also have a third position which is a not fully Closed position.
Each of the showerheads of the overhead shower and the hand-held shower have at least two groups of outlet openings, which provide issuance of water in at least two different patterns. For example, for this purpose the openings of the different groups can differ from each other in their shape, size, location, etc.
As can be seen from FIGS. 1, 2a and 2b, the switch 7 can be located either on the handle 3, or on the connecting member 6, or on the hose 4 of the hand-held shower.
The water shower system in accordance with the present invention as disclosed in detail hereinabove operates for showering of a user in the following manner.
When the switch 7 is moved by a user to an open position, water is supplied through the openings 34 and 32 in the housing 11 into the area 35 of the valve body 18. Under the action of water pressure on the valve member 21 the valve element 19 first moves along a vertical axis 37 downwardly and the valve member 20 closes the opening 27. Then the valve member 21 is compressed, and water forms a gap between the valve member 21 and the wall 36 and flows through the opening 30 to the hand-held shower and in particular to its showerhead 2.
The hand-held showerhead 2 is thereby operated and water issues through it outwardly for showering, as desired by a user. In this manner of operation the water flow to the overhead shower is blocked.
When the user moves the switch 7 to a closed position, a water pushes the valve element 19 upwardly and the valve member 20 opens the opening 27 causing water to flow through the opening 27 and through the channel 14 to the overhead showerhead 8. Thereby the overhead showerhead 8 is operated and water issues through it outwardly from it for showering as desired by a user. In this manner of operation the water flow to the hand-held shower is blocked.
In the shown embodiment, therefore when the switch 7 is in its first open position the valve 9 operates to supply water to the hand-held showerhead 2 and to block water supply to the overhead showerhead 8, while when the switch 7 is moved to its second closed position the valve 9 operates to supply water to the overhead showerhead 8 and to block water supply to the hand-held showerhead 2.
The switch 7 can be also moved by a user to a further position in which is it is not fully closed. In this case the valve element of the valve, under the action of water, periodically displaces along its axis up and down, and a pulsating flow of water issues from the overhead showerhead 8.
In the inventive water supply system the switch is conveniently located in the area of the hand-held shower at a lower height and can be easily reached by a user, and the system provides a water issuance either from the hand-held showerhead, or from the overhead showerhead, or in a pulsating manner.
The water shower system in accordance with the invention is not limited to the details shown since various structural changes are possible without departing from the spirit of the invention.
