US 5,295,721 A · Animal waste pick-up apparatus

Abstract

An apparatus for handling waste such as animal feces to be removed from a ground surface includes an actuator unit and a disposable receptacle. The receptacle includes a jaw portion having hinged jaw members, lower extremities thereof forming respective blade portions, one of the jaw members being movable relative to the other jaw member between an open position for receiving the waste into the receptacle, and a closed position, each of the jaw members having an engagement member for actuation by the actuator unit. A bag of the receptacle is sealingly connected to the jaw portion for holding the waste material in a bag cavity that joins the jaw cavity proximate a partition member that retains the waste in the bag and separate from the jaw cavity, a jaw holder yieldably holding the jaw members in the closed position. The actuator unit includes a handle, a pair of actuator members for supportively connecting the engagement members of the receptacle, and a first actuator for operating the jaw members between the open and closed positions, and a second actuator for tilting the receptacle for moving the waste from the jaw cavity into the bag. The apparatus is operable for positioning the receptacle in contact with the ground surface with the blade members on opposite sides of the waste material by manipulation of the handle and the first actuator; moving the jaw members into the closed position; tilting the receptacle whereby waste material is confined within the bag for permitting multiple pick-ups using a single receptacle; and disconnecting the receptacle from the actuator unit for convenient and sanitary disposal of the waste together with the receptacle.
