DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

(9) Hereinafter, a preferred configuration and operation of the present disclosure for attaining the above objectives will be described with reference to the accompanying drawings.

(11) A typical golf driver 100 is configured to include a head 101 that substantially strikes a ball, a shaft 103 having a tip end 102 coupled to the head 101, and a grip 105 coupled to a butt end 104 of the shaft 103 and enabling a player to hold and swing a club.

(12) The head 101 is configured to include a head body 108 obtained by connecting a flat sole 106 formed on the bottom surface with a round crown 107 on the upper surface thereof, and a face 110 connected to the front of the head body 108 and actually strikes a ball.

(13) The face 110 has a roll formed in a round shape from the top to the bottom and a bulge formed in a round shape to the left and right sides, and the center position of the roll and the bulge is a sweet spot point 113, and a specific portion around the sweet spot point 113 is referred to as a “sweet spot area” 115.

(14) In the present disclosure, a sweet spot plane 116 is formed by flattening the sweet spot area 115 of the face 110, and toe planes 117 and heel planes 118 are also formed on the toe and the heel on the left and right sides of the sweet spot area 115. Thus, when the sweet spot plane 116 strikes a ball, the ball flies correctly, and when the ball is hit on the toe planes 117 and the heel planes 118, clear compensation is able to be performed due to the gear effect.

(15) The spacing between the toe planes 117 and the spacing between the heel planes 118 are determined while maintaining the lines of the roll and the bulge. In this case, the spacing between the toe planes 117 and the spacing between the heel planes 118 may be determined to be large such that the number of toe planes 117 and heel planes 118 are reduced, or the spacing between the toe planes 117 and the spacing between the heel planes 118 may be determined to be small such that the number of toe planes 117 and heel planes 118 are increased so that the bulge line is formed in a stairway shape, thereby providing various configurations.

(16) As another example, in the case of the roll line, since there are only small remaining areas on the upper and lower sides of the sweet spot plane 116, it is desirable to form planes only on both sides of the sweet spot plane 116 along the bulge line, instead of forming planes on the upper and lower sides of the sweet spot plane 116.

(17) The sweet spot plane 116, the toe plane 117, and the heel plane 118 may further have a friction means 120 formed on the surfaces thereof in order to facilitate compensation for the ball to be directed toward the target through the gear effect in which the ball and the surfaces of the face 110 engage with each other while preventing the ball from slipping when striking the ball, and improving the frictional contact with the ball.

(18) If the friction means is formed to have a visually recognizable size, it may affect the thickness of the face 110 and the like, and may damage the surface of the ball when the ball is hit. Therefore, the friction means may be formed to be fine in consideration of the above problem, and may be formed in any of various forms, such as a knurled form, an uneven form, or the like, but is not limited to a specific form.

(19) The operation and effect of the face for a golf driver, to which the technology of the present disclosure is applied as described above, will be described as follows.

(20) As is well known, the driver 100 is used by a golfer who takes a swing to hit the ball through a series of procedures such as holding a grip, addressing the ball in the tee box, backswing, backswing top, lagging, impacting, and follow-through.

(21) In this process, if the sweet spot area 115 of the face 110 strikes the ball, the ball is able to fly away in a correct direction without any resistance. In the present disclosure, since the sweet spot plane 116 is configured by flattening the sweet spot area 115, if the ball is hit within the sweet spot area 115 based on the sweet spot point 113, it is possible to send the ball more correctly and farther away due to the flatness thereof.

(22) In addition, since the toe planes 117 and the heel planes 118 are further formed on both sides of the sweet spot plane 116, even if the ball is not hit exactly on the sweet spot area 115, the toe planes 117 and the heel planes 118 formed in multiple stages on both sides of the sweet spot area 115 along the bulge line may come into contact with the ball to bring about a gear effect, thereby compensating for the ball to be directed toward the center, and then significantly reducing the phenomenon in which the ball is directed to the penalty area out of the fairway and the rough area.

(23) In particular, since the friction means 120 is further provided to the surfaces of the sweet spot plane 116, and the toe planes 117 and the heel planes 118, which are on both sides of the sweet spot plane 116, the ball may be prevented from slipping, and may cause friction therebetween while the ball is hit on the sweet spot planes 116, the toe planes 117, or the heel planes 118, thereby sending the ball correctly and far. In addition, the ball hit on the toe planes 117 and the sweet spot plane 116 may be sufficiently compensated for due to the clear gear effect, and may be directed to the center.

(24) As a result, the obsession in which golfers must accurately strike the ball against the sweet spot point 113 will be removed, so it is possible to use the driver more softly and smoothly. Further, even if the ball is hit on the toe plane 117 and the heel plane 118 provided in the face 110, rather than the sweet spot area 115, the gear effect in which the ball is directed to the target may be obtained through compensation.

(25) In this way, since the golfer is able to maintain psychological stability, it is possible to perform the softer and more stable swing, thereby lowering the frequency of hitting the ball to the penalty area regardless of a golfer's swing stance and trajectory thereof, which leads to securing of psychological stability, a good influence on a shot using another club, and obtaining a good score.

(26) Although the description of the present disclosure mainly relates to the application to the face of the driver, the present disclosure may also be applied to the face of a utility club as well as a fairway wood in the same manner.

(27) The present disclosure described above has advantages of increasing the probability of hitting the ball on the sweet spot area regardless of the golfer's swing stance and trajectory thereof by the sweet spot plane formed in the center of the head face of the driver and the toe and heel planes formed on both sides thereof, improving straightness and driving distance, and compensating for the ball to be directed to the center through the clear gear effect even if the ball is hit on the heel and toe areas, thereby preventing terrible hooks and slices.
