ABSTRACT:
A precise, anatomically configured finger insert for the holes of a bowling ball conforms to the exact size and shape of the bowler's fingers prior to the insert being set into the pre-drilled holes of the bowling ball. The inserts are formed from a soft, resilient elastomer that favors rather than resists the full spectrum of all finger shapes. The insert is vented to eliminate the vacuum effect produced when the fingers are very rapidly removed from a tightly confined space, the venting allowing for ease of finger extraction upon release of the bowling ball, the venting spaces in plurality also allowing the soft deformable elastomer to accommodate finger size change secondary to swelling by pushing into the venting spaces. The method of production of the finger hole inserts yields inserts that are unique and personal for each individual bowler, yet capable of being mass produced. Exact duplication of the insert is possible, making any anatomically configured insert from the same production feel exactly the same in any bowling ball regardless of how many bowling balls the bowler may use.
