DUAL FLUSH TOILET MECHANISM

摘要

A dual flush toilet system includes a mechanism (22) that permits the flush handles (82, 84) to be placed at any location on the toilet tank (12) and even on the top (14) of the toilet bowl if desired. The dual flush valve itself preferably comprises a prior art mechanism (20) attached to a pair of exterior handles (82, 84) by means of a cable and wire system (60, 64). Rotation of an outer handle (82) causes the main float (42) to rise under the influence of first wire (60) thereby causing a small, or low, volume flush to occur. Pushing down on both handles (82, 84) simultaneously causes a float lock (34) to rise which in turn allows a lower float (52) to lift and engage the bottom rim (150) of the float mechanism (20) thereby holding the mechanism (20) up longer and causing the entire contents of the toilet to flush thereby creating a larger volume flush. A certain predetermined amount of play in the two wires (82, 84) permits the float connector (32) and float lock (34) to be pulled upwards, but does not prevent them from moving downwardly when the spring action (110, 112) of the handles (82, 84) returns the handles (82, 84) to the horizontal position. According to an alternative embodiment (180) of the invention, spring loaded push buttons (182, 184) can be mounted on the lid (14) in place of the handles (82, 84).
