1 "SIZING SYSTEM FOR SETS OF GOLF CLUBS"
2
3 FIELD OF THE INVENTION
4 Embodiments of the invention relate to a system for pre-sizing sets of golf clubs and particularly to sets of golf clubs having a single shaft length for 6 irons and a single shaft length for woods, a predetermined standardized swing 7 weight and a standardized angle of lie.
The conventional art of golf club making involves a sophisticated 11 plurality of variables that are often correlated or matched. A matched set of clubs 12 typically has a series of woods and irons of a specific swing weight, graduated 13 shaft lengths and a uniformity in the flexibility of the shafts. In order to obtain 14 equal swing weights between clubs having graduated shaft lengths, the total weight of each club must be varied. There is a correlation between the shaft 16 length and the head weight and loft angle. Further the golf club head must be 17 moved in a controlled arc to bring the head against the ball at the most effective 18 striking angle with a velocity related to the desired distance the ball is to travel.
19 The decreasing length in the shafts of clubs having an increasing loft results in a required swing that is increasingly tighter and more upright.
21 Given the differences in the required swing, a golfer must adjust 22 stance and swing with each and every club in the set to affect a consistent, 23 desired performance, which adds significantly to the difficulty in playing the game 24 of golf.
1 Golfers, particularly those that are new to the game, have difficulty 2 in identifying the correct shaft length for their height and swing. Golf clubs can be 3 custom sized, that is each of the shafts is cut to the correct length for the height 4 and the individuals swing characteristics. Unfortunately, particularly for the novice, their swing has not yet been developed for each and every different club.
6 Expensive custom sized clubs purchased for a novice may quickly become a 7 detriment as the novice's swing is developed. More importantly, however, the 8 golfer may never develop the necessary repertoire of different swings required 9 for the different clubs and thus never learn to apply a consistent, effective swing necessary to utilize the clubs to their best advantage. Many novice golfers give 11 up the game rather than learn to perfect multiple swing techniques.
12 It is known to provide a set of golf clubs having a single shaft 13 length for irons and one for woods or alternatively groups of three or four shaft 14 lengths within the irons and the woods. Such systems are taught in US
patent 3,984,103 to Nix and US Patents 4,971,321 and 5,228,688 to Davis.
16 Nix provides golf club sets having two classes of clubs, that is, 17 woods and irons, with all the clubs in a class having equal lengths and equal lie 18 angles. Nix states the advantages of such golf clubs are that the player can 19 concentrate the training of his body and hands in developing the swing through only one plane of arc for each class of clubs. Further, only one distance between 21 feet and ball need be learned and grip control to keep the plane of the club 22 striking face normal to the arc of the swing is simplified and constant.
The 23 somewhat awkward swing angle for the short clubs of a conventional golf club 24 set, such as the number 9 iron, is avoided. The criticality in position of club at moment of impact with the conventional long clubs like the number 1 wood or 1 iron is reduced. The ultimate simplicity in attaining control is to have clubs of 2 both classes of the same length and lie because the player can concentrate on 3 one arc of swing, one wrist and grip control and one set of coordinate 4 movements of shoulder, arm, hip and knee.
Davis teaches subsets of clubs within a set of irons and woods, 6 each subset having the same shaft length, swing weight and vertical hand height 7 however the lie angle is adjusted between each club.
8 Clubs of unitary shaft length must still be sized for each individual 9 golfer therefore what is required is a standardized sizing system for said clubs in which a golfer may easily select an optimal shaft length for developing an 11 optimal golf swing and may easily add additional or supplementary golf clubs to 12 a set of clubs without altering their optimal swing.
Embodiments of the invention described herein are adapted for use 16 with a set of golf clubs having two classes of clubs, irons and woods, having a 17 single shaft length for each class, as illustrated in Fig. 1 a, in contrast to a 18 traditional set of clubs, as shown in Fig. 1 b, wherein each club within the two 19 classes has a different shaft length.
Further, each class of clubs used in embodiments of the present 21 invention has the same lie angle and the same head weight, the only difference 22 between the clubs being the loft angle. Thus, a golfer would be required to 23 perfect only two stances and swings, one for each class of clubs, which greatly 24 reduces the complexity of the game.
1 As shown in Fig. 2a, the positioning of the ball relative to the 2 golfer's feet is different using a traditional set of clubs. As shown in Fig, 2b, the 3 positioning of the ball relative to the golfer's feet is substantially the same 4 regardless of the club used within each class of clubs.
In an embodiment of the invention, illustrated in Fig. 3, a plurality of 6 pre-sized sets of golf clubs are manufactured, each set comprising two classes, 7 irons and woods, the classes each having a single shaft length, head weight and 8 lie angle. Preferably, the lie angle is about 61 - 62 degrees.
9 Each of the plurality of pre-sized sets has a different and incrementally increasing shaft length therein for both the irons and the woods so 11 as to provide a set of clubs which is substantially optimal for each golfer, 12 throughout a relatively wide range of heights and arm lengths. The shaft lengths 13 are preferably based on ranges of hand measurement from the ground.
14 In an embodiment of the pre-sizing system, a unique identifier is provided for each set, the identifier being preferably numerical and color-coded 16 and related to a particular shaft length suitable for each range of hand 17 measurements from the ground. A measurement tool is provided which is 18 demarcated at each of the ranges of hand measurements from the ground. The 19 golfer positions the tool on the ground adjacent their foot and, while standing upright, extends their arm along the length of the tool. The numericallcolor 21 identifier located adjacent the fingertips identifies the set of clubs from the 22 plurality of sets of clubs that would be most suitable for the golfer.
23 Having reference to Fig. 4, the measuring tool may be provided as 24 a separate tool or may be integrated into the packaging of the set of golf clubs, such as printed on the outside of a box containing a set of clubs.
1 Embodiments of the invention teach a system for providing pre-2 sized sets of golf clubs, adapted for use with sets of golf clubs having a single 3 shaft length for irons, a single shaft length for woods, a standardized club head 4 weight and a single lie angle therein, comprising providing a plurality of sets of golf clubs, each set having an incrementally increased shaft length for irons and 6 woods, identifying each of the plurality of sets of golf clubs with a unique 7 identifier, providing a measuring tool for determining a measurement relative to 8 the unique identifier and measuring the golfer using the measuring tool for 9 determining which of the plurality of sets of golf clubs is optimum for the golfer.
Preferably, the measurement is a distance of the fingertips from the 11 ground and the unique identifiers each represent a range of distances from the 12 ground. The unique identifier may be a number or may be a number and a color.
13 In an embodiment of the invention, six sized sets of clubs are 14 provided, each set assigned a number from 1 to 6 and a color, the colors being blue, green, yellow, orange, red and purple, preferably in that order, and 16 representing an incrementally increasing shaft length for each of the classes of 17 clubs within the set, as shown in Table A.
