Automatic flush valve actuation apparatus for replacing manual flush handles

Abstract

An automatic flush handle actuation apparatus is provided for replacing a manually-activated flush handle of a flush mechanism of a sanitary facility. The apparatus includes an enclosure containing a drive mechanism and a self-contained power source for the drive mechanism. The apparatus also includes means for sensing use of the sanitary facility and means for interconnecting the drive mechanism and power source when the means for sensing detects a use of the sanitary facility. An adaption having first and second ends is included rigidly engaging the enclosure at the first end and a plunger pin having first and second ends slidably extending through the adapted, engaging the drive mechanism within the enclosure of a first end. A threaded nut is provided around the adapter captured on the adapter at a first end by the enclosure and by a hub at the second end of the adapter, the threaded nut, second end of the adapter and a second end of the plunger pin being constructed to operably interact with the flush mechanism in a manner substantially identical to a nut, adapter and plunger pin of the manually-activated flush handle.
