Description

[Detailed Description of the Invention] The present invention relates to a tee used in golf competitions.

In a golf game, the first shot of each hole begins with a tee shot at the teeing ground.

To tee up for a tee shot, place the tee under the ball and stick the leg of the tee into the ground through the ball.

Next, you hit the ball on the tee hard with your club, but if you look at the trajectory of the club head, it will be almost horizontal as it passes the tee.

This means that the ball does not immediately fly diagonally upwards at the moment it is hit, but instead is crushed horizontally.
It becomes longer in the vertical direction.

It moves horizontally for a while in that deformed state.

Next, a repulsive force is generated on the ball, which causes the ball to fly upward away from the club face for the first time.

When the soil on the teeing ground is soft, if you hit the ball hard, the tee will instantly compensate for the deformation of the ball and will be displaced, so there is no big problem, but when the soil is hard, the additional displacement will not occur and the tee will cause the ball to deform. and impede movement.

For this reason, it would be better if the front edge of the tee head did not interfere with the direction of flight of the ball, but this would result in poor ball stability during tee shots.

In order to prevent this tee head from being damaged, there are examples where the head is made entirely of soft elastic material, but the adhesion between this soft material and the remaining hard material is insufficient, and the head If the ball is too soft, there is an inconvenience that the ball's resistance to the ball increases, especially when the ground is hard, and if the head is placed on the same day to make it easier to perform this operation.

This invention eliminates such inconvenience, and the upper end 5 on the diameter line of the head of the tee, that is, the upper edge of the mortar-shaped part 1,
To provide a golf tee in which a part 3 not including the leg part 2 is made of a soft elastic material, and the other part is made of a hard material, with the oblique cut surface passing through the outer root 6 of the rod-like leg part 2 as the boundary.

An embodiment of the present invention will be described with reference to the drawings. As shown in the side view of FIG. It is replaced with an elastic material part 3 and bonded again at the cut surface 1a.

The perspective view of FIG. 2 shows another embodiment, in which there are three grooves 4 as shown in the figure for specifying which direction to tee up when the soft parts exhibit the same color. 4,4
Providing this also has the effect of making the upper edge of the head more flexible.

Next, the function of the golf tee of the present invention will be described.

First, insert the legs 1 and 2 into the soil with the soft elastic material part 3 facing forward, and when you hit the ball with a 1° club that places the ball on the forested part, the club head moves in the direction of the arrow in Figure 3. , which causes the ball to momentarily lengthen up and down.

At this time, the above-mentioned soft elastic material part 3 temporarily deforms outward to the state 3a, but does not apply a reaction force to the movement of the ball, so that the ball is not hindered by the upper edge of the tee and moves in a predetermined direction. Take off.

In this case, the force of the club head's impact is applied to the left side of the tee, not the right side, as shown in Figure 3.

Therefore, as described above, only the elastic material portion 3 of the tee is elastically deformed, and the deformation stress is not strongly applied to other parts.

Therefore, even if the tee is inserted into hard soil, no strong impact will be applied to the tee itself, and the tee will not be damaged.

The above-mentioned beveled surface 1a, which is a joint surface, has a sufficiently large area, so that a strong connection can be obtained even when the two types of materials for the head are manufactured by injection molding at the same time.

In this way, the present invention uses a tee in which a soft elastic material is securely bonded to a part of the head, so that the hard material can pass from the head to the legs without interfering with the movement of the ball or damaging the tee. Because of this, it can be easily penetrated into the ground,
This has great practical effects.
