Abstract:
An apparatus for retrieving an object: more than two claws mounted to a plunger that is movably housed within a cup, the claws extending through a lid of the cup. With the plunger at the bottom of the cup, each claw is retracted into the lid; with the plunger at the top of the cup, each claw extends beyond the lid to a ball-grasping position. At least one claw is bent and resilient. On pressing the tips of the claws against an object, the at least one claw bends apart from the other claws to admit the object between the claws, and on passing beyond a diameter of the object, the tip of the at least one claw springs back toward the other claws to capture the object between the claws.
