Abstract

This invention can create the Reaction efficiently. In Linear Shape, it has the largest sweet spot area as it has two(2) legs to generate the Reaction efficiently. In both 'X' and '+' Shape, having four(4) legs, it has great reaction and carries the ball intentionally though it has less sweet spot area compare to Linear Shape. This reaction can produce the power and leads the power enough to carry the ball further and place the ball with accurate direction in the fairway than the conventional golf club. This unique invention can minimize the strength and tension as the golfer need not to swing too fast to speed up. As it hold the impact power in very short period of time to create the Reaction, it minimize the elbow pain collaterally. Configuring the design, e.g. positioning the legs, length of the crevice and position the crevice., it carry the object intentionally. This would be suitable for the golfer who drives skillful as draw, hook, slice and fade, no matter whether it flies high or low.

Technical Problem

[8] This is about golf club head - Driver, Fairway Woods, and Iron club. [9]

[10] Despite the modern technology, to decrease the weight in golf club head and

[11] create the light material to increase the reaction, has evolved into advanced golf

[12] club heads, however the results not so satisfying yet.

[13] Having the weight of the shaft reduced from 140 gram steel shaft to 40 gram

[14] carbon shaft makes the club head bigger and enlarges sweet spot area. [15]

[16] The result, however, to cany the ball further intentionally is still not achieved.

[17] Because the shaft flexibility created from light weight bends the shaft too early

[18] and too much, so it carries the ball high and misses the intended direction. [19]

[20] Having light weight material can make the big capacity in golf head and enlarge

[21] the sweet spot area. It, of course, brings more reaction.

[22] However, as the face surface is increased, the air resistance on the down swing

[23] needs to be seriously considered. Too large a golf club head will have negative

[24] effect on the air resistance so the consensus of about 400cc is the optimal size

[25] having reaction enough and guide the ball to the intermediate point. [26]

[27] The face thickness in size of 400cc head is around 2 - 4 mm, depends on the

[28] material, has created very limit Moment of Inertia and less reaction as the crown

[29] part(fig. # 5-a) is welded to the upper side of the club face and the bottom is also

[30] fixed to the main body(fig. # 5-b). [31] In figure # 4 ;

[32] The reason for the low Moment of Inertia is because the center part has been

[33] fixed both at the top and bottom. Therefore, as the result of the law of action /

[34] reaction, the ball is released only by its elasticity.

[35] If the reaction at the center of the club face is removed, it leads to further loss.

[36]

[37] To date, the focus of the study on golf technology was on increasing the sweet

[38] spot through reducing the golf club weight.

[39] This led to search for lighter metal - like carbon in shaft - and is applied to golf

[40] club heads, and also to golf shafts in order to make the swing better and easier.

[41]

[42] The weight of club shaft has now been lowered to 40 grams, as an example.

[43] To achieve this, the latest drivers, fairway wood, and even irons have adapted the

[44] breakable thinner club face with empty cavity structure.

[45] Though, the golf club heads have gotten bigger with the light material and sweet

[46] spot has increased proportionately, it doesn't make the things better.

[47] The club manufacturer tends to make the face thinner to have light weight head.

[48] However, this leads to insufficient Moment of Inertia and unclear sound upon

[49] impact. Also, the material wears off fast and leads to cracks.

[50]

[51] In club heads around the size of 400cc with an adequate thickness , it is hard to

[52] expect high Moment of Inertia and sufficient Reaction because its characteristic

[53] both in club shaft's flexibility and club head's reaction.

[54]

[55] This invention is designed for the optimal Moment of Inertia and sufficient

[56] Reaction for 400cc club head so that the user will be able to experience

[57] maximum distance.

[58]

Technical Solution

[59] It is about modifying the most part of the golf club face dividing into three(3) or

[60] five(5) parts to bring out the best result in golf swing. [61]

[62] i) "Linear Shape", ii) "+" Shape and iii) "X" Shape are the consensus of this

[63] invention so that after the ball's impact at the club face, the increased Moment

[64] of Inertia due to this invention will increase the power to get the distance further

[65] and improve the accuracy because of its unique design. [66] [67] [68] In figure # 2 ;

[69] In order to increase the distance, the energy needs to be concentrated, like an

[70] arrow and bow just before its release as seen in fig. # 3.

[71]

[72] In figure # 5 ;

[73] Common way to assemble the golf club head. The crown part(a) is covered on

[74] top of main body(b) by argon welding, and also the club face(c) to the main body

[75]

[76] In figure # 6, called "Linear" Shape ;

[77] Argon welding the major part of club face which can create the reaction mostly

[78] together with the other remaining parts (C & D).

[79] A, B, C & D are also welded simultaneously to the main head body.

[80] The energy is related to the fact of Moment of Inertia, e.g. the arrow is drawn

[81] which equals to figure # 2.

[82] As the impacted area is freely bent, like a bow, it holds the impacted power in a

[83] very short period of time and thus creates the reaction sufficiently compare to

[84] the conventional golf club which has crown (fig. # 5 -a) and bottom fixed.

[85] This energy can be restored as the force that carries the ball out.

[86]

[87] Distance = r -dm dv

[88] dm = mass of the ball,

[89] r = radius (axis of swing to the ball)

[90] dv = index of reaction (about 1.1)

[91] Index of reaction (dv) is simulated and is estimated at about 1.21.

[92] As the force is related to the velocity, in order to carry the ball further it requires

[93] more light material to speed up.

[94] Index of reaction which is created by this invention adds more sufficient power

[95] to force the Reaction from the club face more than conventional club face.

[96]

[97] In figure # 7, called "X." shape ;

[98] Argon welding the major parts together with other remaining 4 parts (E,F,G & H).

[99] Imagine as if two(2) bows are crossed, thus bringing the energy more efficiently.

[100] Though it carries the ball less than the Linear Shape, it carries the ball precisely.

[101] Its sweet spot area is less than the shape of linear due to the 4 legs, meaning

[102] the edges of each of four(4) legs are argon welded and the certain distance

[103] from the welding points have no reaction enough to create the force.

[104]

[105] [106] In figure # 8, called "+" shape ;

[107] Argon welding the major parts together with other remaining 4 parts (E,F,G & H).

[108] Imagine as if two(2) bows are crossed, thus bringing the energy more efficiently.

[109] Though it carries the ball less than the Linear Shape, it carries the ball precisely.

[110] Its sweet spot area is less than the shape of linear due to the 4 legs, meaning

[111] the edges of each of four(4) legs are argon welded and the certain distance

[112] from the welding points have no reaction enough to create the force.

[113]

[114] As in E=mc , the average head speed of pros is about c=l 10 mile / hour.

[115] By this invention, this could be increased by 21% to c=133 mile / hour, so the

[116] distance and accuracy could both be enhanced at the same time.

[117]

Advantageous Effects

[118] Upon the strong impact on the golf ball, the vibration is hit upon the face to the

[119] shaft and all the way to the grip, eventually to the hitter's shoulder.

[120] The impact is sometimes estimated at 2 tons and often brings injury to elbow.

[121] If this impact is absorbed at the golf club face and turned into counter reaction,

[122] then impact to the elbow will be softened and possible injury could be prevented.

[123] Modifying the club face can be effected not only the result of the swing but the

[124] tension of the golfer. It gives the golfer more relief and make the swing better. [125]

[126] In figure # 4 ;

[127] The conventional golf club, the reaction is very limited as the whole edge is

[128] welded, meaning there are no points to produce the reaction enough.

[129] The elastic of each ball and club face are the only factor so it very much relies

[130] on only the speed of the club. [131]

[132] This unique invention can create high reaction and Moment of Inertia because

[133] the enlarged sweet spot area has a tendency to freely bend to produce the

[134] reaction more and it can minimize the strength and tension as the golfer needs

[135] not to swing too fast to speed up the club head.

[136] Need to swing smoothly as it has additional factor, such as high reaction. [137]

[138] In figure # 6 ;

[139] As the sweet spot area is bigger than "X." shape and "+" shape, it can easily

[140] produce the efficient elastic energy, like a spring. The face have been

[141] diversified into "X" Shape in fig. # 7, and "+" Shape in fig. # 8. [143] Figure # 13, # 14, # 15, and # 16 ;

[144] As a result of overall high Moment of Inertia, and the different Moment of Inertia

[145] as a result of the design difference on the face, it will prevent slice or hook,

[146] or Io w traj ectory flight of balls .

[147]

[148] The reaction is greater when the distance between the two crevice is narrow

[149] than when it is wide. Upon the impact of the ball, the narrower side is thrust

[150] backward while the other side(the wider side) does not.

[151] This causes a time gap when the ball is released - this can correct slice,

[152] hook, low, or high trajectory balls.
