ABSTRACT:
A litter and refuse retrieval device is provided for sanitarily and single-handedly cleaning up after a pet. The device includes an outer frame having an upper and a lower portion and an inner frame also having an upper and a lower portion. The upper and lower portions of the respective frames can be connected together to form the assembled retrieval device by interlocking prongs with respective prong receiving openings. The device further includes an outer frame having a handle at one end and outer nipples at the other end for pivotally mounting two scoops. Each scoop includes extended disk portions with holes therethrough that overlap with the disk portions of the other scoop placing the holes in alignment for insertion of the outer nipples of the outer frame. An inner control frame is carried by the outer frame and includes linkage arms having outwardly extending cylindrical portions having nipples extending therefrom for pivotally mounting the two scoops adjacent to the outer nipples. In operation, the inner control frame is squeezed by the user toward a stop potion of the outer frame, causing the scoops to pivot in opposite directions. Also provided is a spring biasing mechanism for closing the scoops after the user has released the inner control frame.
