Overview of Original Patent and Cited Patents

  • The invention I selected is a set of golf clubs that is more unified compared to other previous sets of golf clubs. According to the patent, the lofts, length of the clubs, and face progression (the change in shape of the club) are correlated and coordinated to be more user friendly. The main features of these clubs are that the center of gravity for each club is lower to the ground and more centered on the club face and the club heads for all clubs, including irons, are wider. The wider club heads make all the clubs look similar to woods. Woods are traditionally the easier clubs to hit for the average amateur player. The goal for this invention is to make the game easier and more enjoyable for the average player with a more unified set of clubs. [1]
  • The first cited patent, from 1922, also describes a set of clubs that was invented to make the game of golf easier for the average player. The intent with this invention was to create a more uniform set of clubs for the average player to use. Before this invention, the inventor states that a set of clubs could be comprised a very different mix of clubs. It would take an extensive amount of time to properly train to master the use of all of the different clubs. Therefore, it is nearly impossible for the average amateur player to play very well because there is not enough time in the day to devote to properly training with each club. This invention was a unified set of clubs that focused on the physical properties of the set. The term the inventor used was the length-weight balance. LW=C, where L=length of the club, W=weight of club, and C=constant. Longer clubs will weigh less, while shorter clubs will weigh more. The idea is that this equation will provide some kind of uniformity to the set of clubs. There is also a relationship defined for a proportional balance point throughout the entire set of clubs. [2]
  • The second cited patent, issued in 1975, describes another set of golf clubs invented to make the game easier for players. This time, the set of golf clubs became more uniform based on the characteristic of flexural rigidity. It was previously believed that it was necessary to have the longer clubs, like woods and low number irons to have more rigidity in the shaft than the shorter, higher-numbered irons. The inventor claims that he received better results actually making the longer clubs less rigid than the shorter clubs. He also said that the rigidity could be the same for all clubs. To account for uniform rigidity in spite of clubs that differ in weight and length, the inventor altered the thickness of the hollow shafts as well as layering the shafts throughout the club (i.e. the shafts were not of a uniform width throughout an entire club. It was common for the top of the shaft to be thicker than the bottom of the shaft by the clubhead. [3]
