Abstract
A quick release ball type locking pin is described in which a tubular body is formed along an axis. The tubular body includes an internal bore defined by an internal tubular wall surface, and an external tubular body surface. A locking ball having an outside ball diameter is received within a locking ball retainer socket formed in the tubular body. The retainer socket includes an external opening along the external body surface and an internal socket wall leading into the internal bore. The internal socket wall includes a ball retainer flange formed by a first outer socket wall section and further includes a cross-sectional dimension less than the outside ball diameter. The internal socket wall leads inward with respect to the axis from the external opening to a first edge spaced inward of the external opening. The internal socket wall also includes a flared section leading from the edge to a second edge. A ball receiving section leads inward to the internal bore from the second edge. The ball is movably received in the locking ball retainer socket for movement therein between an outward operative position wherein part of the ball abuts the ball retainer flange and extends radially…
