Abstract: An improved golf club fitting system for fitting a set of golf clubs to a player includes the steps of measuring a player's hand grip strength and selecting a representative golf club having a dead weight directly proportional to the player's grip strength. The club length and the swing weight of the representative golf club are then determined by standard testing procedures commonly used in the golf club industry. A balance index (BI) for the representative golf club is then computed by dividing the dead weight (DW) by the swing weight (SW) (DW/SW=BI) and the balance index (BI) is compared to the dead weight to determine generally corresponding values for the remaining other golf clubs in the set such that the system user can match different irons and woods to the representative golf club thereby creating an ideal matched set of golf clubs for the player.

The expander can be withdrawn into the split end to cause its end to become splayed by the action of a resiliently deformable spring, which biasses the expander towards the locking position.

Abstract: A telescopic putter mounted to a headband is a novelty game that mimics the game of golf. It is played indoors with a lightweight plastic ball and a cup resting on the floor. The game follows the general rules of putt-putt golf, except for the rule that the player must not touch the club with their hands when swinging. Instead the club is attached to the player's head with the use of a headband. Thus, the player must bend over the ball, place their hands on their knees and swing the club by turning their head from side to side. The club has an adjustable length shaft that telescopes in and out to accommodate players of varying heights.

Abstract: The present invention relates to a length-adjustable golf putter primarily for use in putting a ball that is on green into a hole in a golf match. The invention is particularly for solving problems generated in case of short putting. When a player uses a long putter for short putting, gap between a bottom of green and an eye of a player is widened and range of vision is opened out, which lowers concentration, causing a problem that a putting line is not read exactly. Accordingly, an object of the present invention for eliminating mistakes originated from such problem, is to provide a putter whose length can be adjusted depending on putting distance, thereby achieving high putting success rate.
