Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a golf club head applied to a wood club or an iron club, and in particular, it is possible to easily keep a warning of the setting state of the head with respect to a target ball flight line at the time of addressing. As a result, the setup and address posture can be performed accurately and stably, and a feeling of peace of mind can be obtained.

[0002]

[Prior art]

 Golf games are a very mental sport for players to sharpen their nerves with each stroke. Especially, when a miss shot is taken, anxiety occurs on the next shot, which has a significant mental impact. May affect.

For example, when performing a tee shot at the tee ground, the player first stands behind the tee-up ball, defines a flight line connecting the target and the ball, and moves about 1 m ahead of the ball on the line. It is customary to search for a spat and enter the address.

Of course, the detailed procedure of this address varies depending on the tastes and habits of each player, but in general, face the ball slightly away from the player, and then determine the grip from the front of the head. By setting the face to match the ball and setting up so that the shoulders, chest, and stance keep a square, after that, breathing while repeating the waggle in small increments and starting takeback from a stationary state, Swing motion is being performed.

At this time, the player feels anxiety while starting the swing motion from setup, and particularly, the setting state of the head with respect to the target flight line of the ball, that is, as shown in FIG. It becomes the most nervous because I am wondering whether the face surface 2 of the club head body 1 is set up exactly facing the flight line L of the ball B.

As a clue to check such a setup, as shown in FIGS. 4 and 5, a plurality of score lines 2 formed on the face surface 1A of the head body 1 and the face surface 1A of the sole surface 1B The leading edging line 3 formed on the side or the top line 4 formed on the face surface 1A side of the blade 1C is visually checked as a guide to identify the warning.

[0007]

[Problems to be solved by the device]

 However, in the above-described conventional golf club head, in particular, each score line 2 formed on the face surface 1A of the head main body 1 has a U-shaped cross section as shown in FIG. 21. When these are visually inspected E from above at the time of addressing, the width W of the lower inner surface 21a of the concave groove 21 is small and the loft angle θ is small, so that it is not conspicuous. There was a problem in that it was not possible to obtain a sense of peace of mind by promoting anxiety about the head setup and address posture when addressing.

[0008]

[The purpose of the device]

 The purpose of this invention is to make it possible to easily identify the warning of the setting state of the head with respect to the target ball flight line at the time of address, and to maintain the setup and address posture accurately and stably. In addition, it is to provide a golf club head that is mentally secure.

[0009]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a golf club head having a score line composed of a plurality of U-shaped concave grooves on the face surface of the head body. In this configuration, at least two concave grooves are chamfered so that the upper inner surfaces thereof face outward and upward in a widened inclined state.

In this case, the chamfering angle of the upper inner surface of the groove forming the score line is preferably in the range of 30 ° to 60 °, and is not conspicuous at 30 ° or less, and the width of the groove is enlarged at 60 ° or more. It is the same as No. 1 and is too wide, which adversely affects the spinning effect.

[0011]

[Action]

 That is, according to the present invention, by adopting the above configuration, the upper inner surface of the U-shaped concave groove of the plurality of score lines provided on the face surface of the head body is expanded and inclined toward the outer upper side. Since the chamfer is made into a chamfer, the visible width of the lower inner surface of the groove is large when viewed from above at the time of address, and it is very conspicuous even if the loft angle becomes small. It is possible to easily identify the warning of the head setting state with respect to.

As a result, the setup and address posture at the time of address can be performed accurately and stably, and the movement of the head at the time of gripping or takeback can be easily grasped. can get.

[0013]

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings shown in FIGS. In the illustrated embodiment of the golf club head according to the present invention, the same parts as those of the conventional golf club head shown in FIGS. 3 to 6 will be described with the same reference numerals.

That is, the golf club head according to the present invention, as shown in FIGS. 1 and 2, has a plurality of scorelines 2 provided on the face surface 1 A of the head body 1 and having a groove 21 having a U-shaped cross section. The upper inner surface 21b of the concave groove 21 is chamfered in a diverging inclined state toward the upper side. In this case, the chamfering angle α of the upper inner surface 21b of the groove 21 is 30 to 60 °. Ranges are preferred.

Therefore, according to the above configuration, the upper inner surface 21b of the U-shaped concave groove 21 of the score line 2 formed on the face surface 1A of the head main body 1 is expanded and inclined toward the upper outside. As shown in FIG. 2, when the head main body 1 is visually inspected E from above at the time of addressing, since the chamfering is performed within a desired angle α, the width of the lower inner surface 21a of the concave groove 21 of the score line 2 can be seen. Even when W becomes large and the loft angle θ becomes small, it is very noticeable, and it becomes possible to easily identify the warning of the setting state of the face surface 1A of the head body 1 with respect to the target flight line L of the ball B. .

In the above embodiment of the present invention, the iron club is described as an example of the head main body 1, but it goes without saying that the present invention is also applicable to the head of a wood club.

Further, in the above embodiment, the upper inner surfaces 21b of all the number of the concave grooves 21 of each score line 2 provided on the head body 1 face surface 1A are chamfered, but at least two or more of them are chamfered. If so, it is possible to exert the effects of this invention.

[0018]

[Effect of device]

 As is clear from the above description, the present invention chamfers the upper inner surface of the U-shaped concave groove of the plurality of score lines provided on the face surface of the head main body in the expanded tilted state toward the upper outside. Therefore, when viewed from above at the time of addressing, the visible width of the lower inner surface of the concave groove becomes large, and it can be made conspicuous even if the loft angle becomes small.

As a result, it is possible to easily identify the warning of the setting state of the head with respect to the target flight line of the ball, and it is possible to accurately and stably perform the setup and address posture at the time of addressing. Since the movement of the head during gripping and takeback can also be easily grasped, it is possible to obtain a mental sense of security and to expect to increase the probability of accurate shots.
