Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION This invention relates to golf clubs, and more particularly to a set of golf clubs having varying grip diameters designed to achieve optimum force, distance, maneuverability and accuracy.

[0002]

BACKGROUND OF THE INVENTION It has been recognized for many years that the design of the grip of a golf club is an important factor for the player to accurately and accurately hit the golf club to exert its power and increase the flight distance. . This is pointed out, for example, in U.S. Pat. No. 4,123,055 issued Oct. 31, 1978 by Hari M. Brill. The use of fingers and palms to manipulate and perceive a club is well recognized and pointed out by many skilled artisans, for example Englewood, Cliffs N. et al.

Pointed out by Elliott. The diameter of the club grip is a very important factor that determines how a player uses his fingers and palm when manipulating the club,
While the type of manipulation required varies with the swing used for each club in the set, all clubs in conventional club sets are made with the same grip diameter. Thus, the same grip size is used both for drivers who make a maximum body turn and a swing that uses full striking force, and for pitching wedges that make a swing with a small body striking force and body swing. Skilled golfers generally know to adjust their fingers and palm in order to compensate for this, as clubs with grips of the same diameter are used in sequence. Performing compensation operations is generally beyond the average golfer's skill level.

Each club in a set of golf clubs is designed with the primary purpose of making the club long for long-distance flight and short for accurate flight. These are the primary goals of such clubs. Along with the length of the club, the loft of the club, that is, the face angle also has a great influence on the flight distance and accuracy of the ball. For example, # 1 wood is the longest club in the set and also has the smallest loft. This long length and small loft produce a greater distance when hitting a ball with No. 1 wood compared to hitting with the shortest shaft in the set, the sand wedge with the largest loft. ing. It should be noted that the putter, which usually has the shortest shaft and a loft of only 4 degrees, is not considered to be included in the club set. The putter was not designed to be included in the club set,
Sold as an independent club.

It is therefore clear that each club should be designed with its own specifications in order to achieve its main objectives. The present invention seeks to provide a grip size that contributes to achieving this end. It should be noted that clubs designed for women have the same loft as those for men, but are generally about 1 inch shorter in length than men.

According to the present invention, the grip of each club in the set is given a variety of diameters so as to have good operability and accuracy when using the club, and to obtain a hitting force and a flight distance. Provide a set of clubs. The grip diameter for each club in the set is determined by the following considerations. When using a golf club, this arm is formed between the player's wrist and the point at which the player grips the club. Given that golfers consider holding a small diameter club with their fingers rather than their palms, the smaller diameter club grip results in a longer lever arm, resulting in greater hitting force and flight distance from the swing. Therefore, for low number clubs where flight distance and force are the primary goals, a smaller diameter club grip is required. On the other hand, in middle or short irons (higher numbered clubs), where force is less important and accuracy is more important, a larger diameter club grip is required to facilitate a strong grasping action by the palm of the player. Thus, the diameter of each club grip within the club set is designed to provide optimum club performance for its intended purpose. Therefore, one of the objects of the present invention is to
It is an object to provide a set of golf clubs in which the grip diameter of each club is designed separately for optimal performance. Other objects of the present invention will become apparent from the following description with reference to the accompanying drawings.

1 and 2 show a set of irons for a golf club of the present invention. Club grip diameters D ₁ -D ₁₁ range from 1 iron to wedge (PW and S
It gradually increases as one goes to W). In the first embodiment, this increase is linear, but non-linear forms of increase could also be used. A linear increase in grip size is desirable and most effective for most players, but top amateur and professional golfers
You will benefit greatly from the grip size increasing somewhat for each club. In this non-linear increase configuration, the maximum increase in diameter occurs between clubs number 1 and 2, with a slight decrease in diameter between subsequent numbered clubs. Some "average" (average) golfers may find clubs with non-linearly increasing diameters to be more comfortable and deliver the optimal performance desired, while some professionals It should also be noted, however, that some people may prefer clubs with a linear increase in grip size.

About 5.08c from the top of the grip cap
The following grip diameters, measured at a distance "D" of m (2 inches), are used in each of the following categories for club No. 1 of the first embodiment: Men's grip --22.606 mm (0.890 inches) Women's grip --22.098 mm (0.870 inches) In the first embodiment, the club grip diameter D ₁ -D.
₁₀ is about 0.2286mm (0.0
09 inches). The two wedges PW and SW have the same diameter in consideration that the shots by these two clubs are very similar. In clubs with a non-linear diameter increase, the amount of increase in grip size is not constant and decreases slightly from club to club as it moves from the second club in the set to the other clubs. It should also be noted that the same grip size is used for similarly numbered woods and irons. Grip sizes for an average male golfer, according to various embodiments of the invention, are as follows: Linear change Non-linear change Club count Size change Size change mm (inch) mm (inch) mm (inch) mm (inch) (iron and wood) 1 22.606 (0.890) 0.229 (0.009) 22.606 (0.890) 0 ( 0) 2 22.835 (0.899) 0.229 (0.009) 22.936 (0.903) 0.330 (0.013) 3 23.063 (0.908) 0.229 (0.009) 23.241 (0.915) 0.305 (0.012) 4 23.292 (0.917) 0.229 (0.009) 23.520 (0.926) 0.279 (0.011) 5 23.520 (0.926) 0.229 (0.009) 23.774 (0.936) 0.254 (0.010) 6 23.749 (0.935) 0.229 (0.009) 24.003 (0.945) 0.229 (0.009) 7 23.978 (0.944) 0.229 (0.009) 24.206 (0.953) 0.203 (0.008) 8 24.206 (0.953) 0.229 (0.009) 24.384 (0.960) 0.178 (0.007) 9 24.435 (0.962) 0.229 (0.009) 24.536 (0.966) 0.152 (0.006) PW, SW 24.663 (0.971) 0.229 (0.009) 24.663 (0.971) 0.127 (0.005) For average female golfers, or golfers with hands larger or smaller than average size, the club-to-club displacement is linear. Both the linear and the non-linear changes are the same as for the average male golfer described above. However, the grip diameter of club # 1 is different for people with large or small hands. As mentioned above, the average female golfer's No. 1 club has a grip diameter of 22.098 mm (0.870 inches). The grip diameter of the No. 1 club for all golfers is 20.320mm depending on the size of the hand.

In this way, according to the situation, various settings are set for each club so that desired operability, accuracy, force and flight distance can be obtained. While the present invention has been described and illustrated in detail, it is intended for the purpose of illustration and illustration only, and not of limitation, the scope of the invention being limited only by the appended claims. It should be clearly understood that it should.
