Description

[Brief explanation of drawings]

Drawing ■ shows the positional relationship between the ball and the hitting surface of the putter head method of the present invention. The vertical axis of the surface is perpendicular to the grass surface and perpendicular to the diameter axis of the pole equator. Figure 1 of Drawing H is a type of conventional putter, Figure 2 is an embodiment of the present invention, where 1 is the head, 2 is the ball hitting surface, 3 is the handle, and a is the height of the head. , S is the hitting spot, Z is the horizontal line of the upper limit of the hitting spot, and R is the curved surface. Figures 3 to 6 are cross-sectional views of the head. Figure 3 shows the hitting spot where the upper limit of the horizontal line Z forms a plane perpendicular to the grass surface to the top of the ball hitting surface, and Figure 4 shows the hitting spot. A plane is formed perpendicular to the grass surface by a certain distance from the center of the spot, and the upper part is set back like a Y to make it easier to see the ball hitting surface and the tool in contact with the ball. The one with a biased type X that protrudes from the rear, No. 6
The figure shows biased type X placed above and below the back of the head. FIGS. 7 and 8 are side views of the eccentric type X, showing the head obliquely from the rear. 6 /da”-[S/F Amendment 3/29/1980 The scope of the claims for utility model registration is amended as follows. O The scope of claims for utility model registration As shown in Figure 1, the bottom of the putter head is in contact with the grass and its ball hitting surface is in contact with the equator of the golf pole, then the height of the putter head I in a positional relationship where the diameter axis of the pole at that point of contact and the vertical axis of the ball hitting surface form a right angle. a is about three-quarters of the diameter of the pole, the center of the hitting spot S is at a height approximately equal to the radius of the pole from the bottom of the ball-striking surface 2, and the upper horizontal line of the hitting spot S is A certain distance above Z or up to the top of the ball hitting surface is a plane perpendicular to the grass surface, and below that point, draw a curved surface R toward the rear and retreat, and the lowest surface of the bottom surface is the circumference of the curved arc R. Putter head structure at the bottom.

Claims (1)

[Scope of utility model registration request] As shown in Drawing I, when the bottom of the putter head is in contact with the grass and its ball-striking surface is in contact with the equator of the golf ball, the diameter axis of the ball at that point of contact and the vertical axis of the ball-striking surface form a right angle. In terms of positional relationship, as shown in Drawings I and H, the height a of the putter head 1 is approximately three-quarters of the diameter of the ball, and the height a from the bottom of the ball-striking surface 2 is equal to or equal to the radius of the ball. The center slightly above that point is the center of the hitting spot S, and the plane perpendicular to the grass surface is a certain distance above the upper limit of the horizontal line 2 of the hitting spot S, or up to the top of the ball hitting surface. is a curved surface R toward the rear
The structure of the putter head is such that the lowermost surface of the bottom surface is the lowest point of the circumference of the curved arc R.
