US 5,330,392 A · Finger grip insert providing size compliance

Abstract

A finger grip insert has a tubular resilient body with an outer wall having at least one recessed section with a concave shape. The center of the tube is shaped to accommodate a human finger. The deformable insert fits into a bowling ball finger hole, and has two sections. The first section extends from the outer surface of the bowling ball to the bowler's fingertip when the finger is placed into the insert. The outer wall of the first section has one or more recesses formed that extend only partially through the tubular body to permit the insert to deform within the finger hole in the area of the recess, responsive to pressure from the bowler's finger. The second section extends from the bowler's fingertip to the end of the insert, and provides a surface to attach the insert to the bowling ball finger hole.
