Abstract
A liquid supply device is disclosed which includes a reservoir and a supply tube for providing liquid to a basin. A shut-off valve includes a support structure for retaining the supply tube to the basin. The shut-off is attached to the supply tube and engages the support structure so as to automatically discontinue liquid flow in the event that the supply tube becomes disengaged from the support structure. Several types of shut-off valves are disclosed for use with the present invention including a pinch valve, a ball valve and a duckbill valve.
Claims15
A supply device for providing a liquid to a basin, said supply device comprising:
- a reservoir for retaining the liquid and providing a liquid flow therefrom, wherein said reservoir is at a position remote from the basin;
- a supply tube for connecting the liquid flow from the reservoir to the basin;
- a support structure for retaining said supply tube to said basin;
- and
- a shut-off valve attached to the supply tube and in mechanical engagement with the support structure;
- biasing means for biasing the valve into a normally closed sealing engagement position;
- a retaining section for holding the valve in an open position to permit liquid and air flow therethrough, wherein the biasing means automatically discontinues liquid flow-through the valve in the event that the supply tube is disengaged from the support structure.
A supply device for providing a liquid to a basin, said supply device comprising:
- a reservoir for retaining the liquid and providing a liquid flow therefrom;
- a supply tube for connecting the liquid flow from the reservoir to the basin;
- a support structure for retaining said supply tube to said basin;
- and
- a shut-off valve attached to the supply tube and in mechanical engagement with the support structure for automatically discontinuing liquid in the event that the supply tube is disengaged from the support structure, wherein the shut-off valve comprises:
- sealing means for sealing the supply tube in order to discontinue the liquid flow to the basin;
- and wherein the support structure comprises a valve key, secured to said basin, for locking said sealing means into an open position for permitting liquid flow, wherein upon disengagement of the valve key, the sealing means seals the supply tube.
