Abstract

PROBLEM TO BE SOLVED: To form a face of only a sweet spot capable of reducing a sway of a head and capable of deciding directionality in a gate ball stick and a ground golf club. SOLUTION: A face of only a swet spot 2 is formed on a ball hitting surface of a stick 1 or a head. An air chamber elastic raw material 3 or an elastic raw material of a synthetic resin is fitted in the ball hitting surface of the stick 1 or the head by forming a clipping groove of the face 2 of only the sweet spot by clipping the part of the face of only the sweet spot 2. Afterwards, the surface of the elastic raw material of the synthetic resin is formed in a hard quality.

Description

DETAILED DESCRIPTION OF THE INVENTION

[Industrial Application Field] The present invention forms a face having only a sweet spot on a surface of a gate ball stick or a ground golf club which hits a ball. Alternatively, cut out only the sweet spot part deeply deeply, and insert a light elastic material, elastic material, or air chamber elastic material at that position, so that the face becomes a sweet spot only face, that part is light and the periphery is heavy Become.
The impact of hitting the ball is absorbed into the elastic material, so that the head does not run out and swings straight. Also, the surface of the face with only the sweet spot is hard and elastic inside, and its specific gravity is heavy around the face, so when it hits the ball, even if it deviates from the core, the timing of repulsion is delayed, and a hollow throw can be taken The present invention relates to a face having only a sweet spot, which does not largely deviate and whose directional property is determined.

2. Description of the Related Art Conventional gate ball sticks and grand golf clubs have aimed at colliding a hard object with a hard object and rolling the ball with the repulsive force. And, it deviated greatly to an unexpected direction, the direction was not decided, and it took time to improve. Also, due to the collision of solid objects, the sound of the collision was high, and the impact was transmitted to the body, making it easy for fatigue.

[Problems to be Solved by the Invention] In order to eliminate the drawback, a face having only a sweet spot is formed on a surface on which a ball is hit. Alternatively, a portion only of the sweet spot is cut out largely and deeply, and a resilient material having a low specific gravity or an air chamber resilient material is fitted at the position to form a face having only the sweet spot. The aim is to develop a face with only sweet spots for gate ball sticks and grand golf clubs, which improves the maneuverability by delaying the rebound when hitting the ball and increasing the hollow throw, thereby improving the maneuverability.

[Means for Solving the Problems] The means for solving the problems will be described with reference to the drawings. (1) Stick (8) Head (4) The ball hitting surface, (2) Sweet spot Only form a face. (2) Cut out (2) the face portion of the sweet spot only, (9) form the cutout groove of the face of the sweet spot only, 3) Fit elastic material in air chamber or (6) elastic material of synthetic resin. C) (6) The surface of the elastic material of the synthetic resin is formed (10) hard. D, only (8) head for grand golf club (7)
Forming shaft removal screws

[Action] The structure described above is used, and by using this, the face of only the sweet spot on the ball hitting surface of the gate ball stick and grand golf stick is an elastic material having a light specific gravity, and the periphery is It is made of a material with a high specific gravity, and when a ball is hit, the impact is absorbed into the elastic material. As a result, the timing of the repulsion is slowed down, the ball is transported as if it were on the surface, and a large hollow throw can be taken, so that the directionality is determined and the ball rolls well. In addition, since the impact is absorbed into the elastic material, the impact is soft and does not reach the body, the impact sound is low, it is healthy, and it also prevents noise. By forming the screw for attaching and detaching the shaft to the head of only the grand golf club, it is convenient because it becomes compact for carrying and storing.

[Embodiment] The combination can be freely performed, and the front face can be used differently.
It can be applied to other clubs.

[Effect of the Invention] By delaying the repulsion timing, a large hollow throw can be taken, the head does not run out, the directionality is accurate, and the ball can be reliably hit to a target place. .

Claims (1)

[Claims] 1. A face having only a sweet spot is formed on a face on which a ball is hit. Alternatively, a portion of only the sweet spot is cut out to be large, deep, and cut out, and an elastic material having a low specific gravity is fitted at that position, so that the face becomes only the sweet spot and the periphery thereof becomes heavy. When the ball is hit, the rebound timing is delayed by the elastic material, and the hollow throw is increased and the directionality is determined by taking a large hollow throw. Face with only sweet spot configured as above
