Abstract:
1. A fingertip grip system for enabling release of a bowling ball in a manner maximizing lift and spin of the ball comprising: a bowling ball having finger holes and a thumb hole of a spacing such that only a middle finger tip, a ring finger tip and a thumb, respectively, of a bowler may be inserted into said finger holes and said thumb hole up to about a first interphalangeal joint, a circular insert mounted in an upper region of each of said finger holes, each said insert having an upper surface and lower surface, each said circular insert further having a central opening therein for receiving a respective one of said tips of said middle finger and said ring finger, said central opening being slightly larger than a respective one of said tips of said middle finger and said ring finger of a bowler, each said insert configured with a thickness such that an end of said middle finger tip and said ring finger tip extend completely past said insert and into a respective said hole, said upper surface of each said insert being proximate a surface of said bowling ball and each said lower surface of each said insert positioned about halfway into a respective one of said finger holes and defining a single, inner lip inside a respective one of said finger holes, each said lip positioned to engage a middle region of a respective one of said tips of said middle finger and said ring finger so that said finger tips provide a dominant upward force in releasing said ball, whereby increased lift and spin of said bowling ball are obtained and a bowler feels through said fingertips a proper way to achieve said increased lift and spin of said bowling ball.
