Abstract:
A flush activation system for controlling the drainage of water from a toilet flush tank during a flush comprising:(a) a valve assembly including a valve member displaceable between open and closed positions for respectively initiating and terminating the drainage of water from the flush tank;(b) a displaceable flush lever assembly coupled to said valve assembly for actuating the displacement of said valve member from said closed position to said open position;(c) at least one auxiliary assembly coupled to said flush lever assembly, said auxiliary assembly including an activating arm having at least one activating float component coupled adjacent a terminal end thereof, said activating arm being pivotally displaceable between angularly offset active and inactive positions, said activating arm being biased in orientation at said active and inactive positions in angularly opposed directions away from a vertical orientation, said activating arm in said active position actuating at least a portion of said flush lever assembly to maintain said valve member in said open position during the drainage of water at least until the water level within the flush tank drops beyond a predetermined activating water level; and,(d) an actuation assembly coupled to said auxiliary assembly, said actuation assembly being operable in at least one mode to displace said activating arm of said auxiliary assembly to said active position thereof.
