Toilet valve lever interlock

摘要

A dual flush toilet assembly including a locking mechanism that prevents over travel of a piston, thereby preventing inadvertent full flushing when only a partial flush has been selected, yet permits full flushing when so desired. Specifically, a rotatable locking mechanism that prevents the piston from moving fully upwards into the second latched position when a partial flush is desired, yet rotates to an unlocked position to permit the piston to move fully upwards into the second latched position when full flushing is desired.

主权项

1. A dual flush toilet assembly, comprising:
a frame; a piston moveable up and down within the frame; a lever mounted to the frame for lifting the piston, wherein the lever lifts the piston partially upwards to a first latched position for a partial flush and fully upwards to a second latched position for a full flush; and a locking mechanism mounted to the frame, the locking mechanism being moveable between a locked position that prevents the piston from moving fully upwards into the second latched position, and an unlocked position that permits the piston to move fully upwards into the second latched position, wherein the lever moves the locking mechanism into the unlocked position when the lever lifts the piston into the second latched position.
