ABSTRACT:
An apparatus for retrieving disbursed objects of various forms, and most importantly spherical objects, such as balls from a surface, such as the ground's surface, comprising a hollow tube having a centrally located longitudinal axis, a first and a second end with an opening at each end, detents located internally within and connected to the hollow tube near the first end of the tube, and a grip attached to the outside of the hollow tube near the second end of the tub. The detents are generally positioned in a single plane oriented orthogonally to the longitudinal axis and in close proximity to the first end of the hollow tube. In retrieving objects, the opening at the first end of the tube is positioned over the object to be retrieved. Downward pressure is applied to the grip to force the hollow tube down and over the object to be retrieved. The detents are initially forced away in a radial direction from the longitudinal axis, permitting the object to be retrieved to pass upward within the hollow tube past the location of the detents. The detents then return to their initial position retaining the object to be retrieved within the hollow tube at a location above the plane of the detents.
