Abstract:
1. An improved bidet device of the type having a frame to mount the device between the toilet bowl, a handle mounting a water tube that passes over the rim of the bowl to the interior thereof, said handle mounted to the frame for rotation of the tube from a rest position to positions for spraying the underside of a torso of a person seated on the bowl, said tube including spray holes, a supply of water for supplying water to the tube for spraying of the torso through the holes and a valve For opening the supply of water to the tube as the handle and tube are rotated from the rest position and closing the supply when the handle is returned to the rest position, said improvement comprising: said handle including a hollow capstan rotatable therewith, said capstan having at one end a first hole adapted to communicate with the supply of water and at the other end a second radial hole adapted to communicate with the tube, said capstan first hole having a shoulder disposed, at the water supply side of said radial hole and said capstan having at the second end internal threads; a screw having a shank with a substantially axial through bore and with external threads to be threadably received into and close said capstan second end and to couple the handle to the capstan for rotation of the capstan with the handle to rotate the tube and open and close the supply of water through the capstan and tube, said shank further including a radial port to rotatably register with the capstan second hole, said screw through bore including a reducing second shoulder disposed to locate the radial port between said first and second shoulders; an actuator coupled to the screw to rotate the screw relative to the handle to position the port between a closed position where the port is positioned to not register with the second opening to prevent the flow of water to a full position where port is fully registered with the second hole for full flow of water through the tube to modulate the flow and pressure of water through the tube and spray holes, said actuator further including a vent to vent the screw through bore to atmosphere; and a plug disposed and captured between said first and second shoulders, supply of water to the capstan bore urging the ball to move from the first shoulder to seal against said shoulder to close the through bore and vent during said supply of water to the tube and movement of the handle to the closed position allowing the ball to move to the first shoulder to seal against the same to prevent back flow of water to said water supply and to open said communication between the vent, screw through bore and tube for venting of the same.
