  • Patent number: 11542697
    Abstract: A gear driven trip lever for a toilet comprises a handle, a handle stop and a torsion spring disposed outside the tank. Inside the tank is a gear driven trip lever subassembly comprising a home position rack that is secured to a mounting plate and a spring-loaded clutch cam. The end of the flush lever nearest the gear driven trip lever subassembly is configured as a geared structure that meshes with gears disposed on a home position rack. When a user pushes the flush handle, the home position rack lifts the geared flush lever. The clutch cam contacts and slides on the home position rack as it moves downwardly. When the flush handle is fully depressed downwardly, the clutch cam releases the home position rack which returns to its home position via a compression spring and the geared flush lever is returned to its home position.

  • Patent number: 10865554
    Abstract: The fill valve and assembly provides an elongated cylindrical water supply tube and a valve seat disposed atop the water supply tube. The valve seat comprises a circular inner valve seat portion and a circular outer valve seat portion between which extend support structures in the form of a plurality of lands and spokes. A bridge is disposed in the center of the valve seat structure about the inner valve seat portion and atop the plurality of lands and spokes. A main diaphragm valve is disposed atop the valve seat structure such that the bridge is disposed between the valve seat structure and the main diaphragm valve. The present invention provides for a thinner and softer durometer EPDM material for the main diaphragm which is advantageous for improved function while the bridge prevents the thin section of the main diaphragm valve from being abraded or cut when high pressures try to push the diaphragm into the spokes.
