Tap group
A tap group comprising a tap body provided with at least one dispensing exit, an operating lever or knob, a regulation member of the parameters of the flow of water to be dispensed (the parameters including the temperature and/or the flow of water and/or the direction of the flow), and a transmission including gears which operatively connect the operating lever or knob to said regulation member of the flow of water. Advantageously, the gears create a gear ratio between the operating lever or knob and a control rod of the regulation member of the parameters of the flow of water, so as to reduce the rotation of the control rod of the regulation member for the same rotation of the operating lever or knob. The tap group also includes a ring-nut provided with at least one indicator and/or a reference index of the parameters of the flow to be dispensed.
1. Tap group comprising:
a tap body provided with at least one dispensing exit,
an operating lever or knob, wherein the operating lever or knob is a body fitted with a lock/release button of the position of the operating lever or knob in a predefined regulation of a flow parameter, said lock/release button being positioned on a base of the body of the operating lever or knob, perpendicular to a lateral gripping surface of said knob,
a regulation member for regulating flow parameters of water dispensed from the dispensing exit of the tap body, said parameters comprising the temperature and/or the flow of water and/or the direction of the flow of water,
transmission means which operatively connect the operating lever or knob to said regulation member of the flow of water,
wherein the transmission means create a gear ratio between the operating lever or knob and a control rod of the regulation member of the flow of water, so as to reduce the rotation of the control rod of the regulation member for the same rotation of the operating lever or knob,
wherein the group comprises a ring-nut provided with at least one indicator and/or a reference index of the parameters of the flow to be dispensed, the ring-nut being separate from the operating lever or knob, being placed on the group so as to be visible to the user, and being integral with the control rod of the regulation member so as to visualize in real time the modification of the flow parameters set by the user following operation of the operating lever or knob.
2. Tap group according to claim 1 , wherein the regulation member comprises a mixer cartridge.
3. Tap group according to claim 2 , wherein said mixer cartridge is a thermostatic type cartridge.
4. Tap group according to claim 1 , wherein the regulation member comprises a flow rate regulator.
5. Tap group according to claim 1 , wherein the regulation member comprises a flow deviator for changing the direction of the flow of the dispensed water.
6. Tap group according to claim 1 , wherein the ring-nut is a body provided with indicators of the parameters of the flow to be dispensed, and a corresponding reference index for said parameters is placed on the tap body.
7. Tap group according to claim 1 , wherein the ring-nut is a body provided with at least one reference index of the parameters of the flow to be dispensed, and the corresponding indicators of the flow parameters are placed on the tap body.
8. Tap group according to claim 1 , wherein the transmission means comprise planetary type gears.
9. Tap group according to claim 1 , wherein the transmission means comprise speed reducing gears, attached to the operating lever or knob at an entrance pinion, the speed reducing gears reducing the movement of the operating lever or knob on an exit pinion, said exit pinion being engaged on a socket integral with said ring-nut.
10. Tap group according to claim 9 , wherein the socket of the ring-nut is in turn fitted and integrally coupled in rotation to the control rod of the regulation member, so that the transmission of the movement to the control rod takes place by means of the socket of the ring-nut.
11. Tap group according to claim 9 , wherein the speed reducing gears are housed inside a box so as to be protected from infiltrations of water.
12. Tap group according to claim 1 , wherein said lock/release button can be operated by pressure and an at least partial rearward movement inside said inner volume defined by said lateral gripping surface of the operating lever or knob.
13. Tap group according to claim 1 , wherein the tap body, the operating lever or knob and the ring-nut are bodies globally cylindrical and coaxial to each other in relation to a same main extension axis.
14. Tap group according to claim 1 , wherein the tap body, the operating lever or knob and the ring-nut are cylindrical bodies all having the same outer diameter.
