BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described in more detail with reference to the accompanying drawings.

In the embodiment shown in FIGS. 1 to 3, a tee-up is performed by using a synthetic resin molded product in which a hollow cylindrical ball support portion 3 is provided above a hollow flat truncated cone-shaped ball seat portion 2. The ball base 1 is configured.

In the embodiment of the second invention shown in FIGS. 4 to 6, the ball supporting portion 3 is formed into a cylindrical shape by a plurality of (eight) thin rods 4 arranged in an annular shape and arranged vertically. The effective diameter D of the head 3a of the ball support 3 can be freely changed to D 'by elastic deformation of the narrow rod 4 as shown in FIG.

In the embodiment, the ball support portion 3 and the ball seat portion 2 are made of the same material, the ball seat portion 2 is thicker and heavier than the ball support portion 3, and the ball support portion 3 is thinner. At the same time, the rods 4 are elasticized. The degree of elastic deformation can be freely changed by selecting the thickness, width and number of the thin rods 4 constituting the ball support portion 3, and the elastic deformation of the head 3a can be arbitrarily set. The material is changed between the ball support portion 3 and the ball seat portion 2, and the ball support portion 3 is made to have a desired elastic deformation even when the ball support portion 3 is formed of a cylindrical body of a soft synthetic resin molded product from the ball seat portion 2. In - Wear.

The above-described elastic deformation of the ball support portion 3 not only facilitates the support of the golf ball, but also allows the resistance of the head to be elastically deformed. In order to avoid the resistance, the golf ball does not fly with the shot at the same time as the shot, and the bead of the head is transmitted to the club as it is on the shot.

FIGS. 8 to 11 show an embodiment of the third invention of the present application, wherein the axis Q of the ball support 3 is eccentric with respect to the center P of the bottom surface 2 b of the ball seat 2, and the ball seat 2 The upper surface 2a has the same axis as the center Q of the ball support portion 3, and the upper axis and the lower axis are eccentric.

FIGS. 12 to 14 show an embodiment of the fourth invention of the present application, in which an image line 5 in the radial direction is displayed on the surface R of the ball seat portion of the image area. ^Five

As shown in Fig. 14, the image line 5 of his own image is visually recognized by the tossing player together with the crescent shape of the surface R of the ball seat portion of the image area.

FIG. 15 shows various embodiments in which the height of the ball support 3 is changed. In golf play, a golf club having an appropriate height according to the player's preference and the difference in the club to be used is shown. select.

Table 1 shows the dimensions of the main parts for each of (a), (b), (c) and (d) in FIG.

No.

FIGS. 16 to 18 show various embodiments in which the ball seat 2 is a polygonal frustum. FIG. 16 is the first invention, FIG. 17 is the third invention, and FIG. FIG. 8 shows each embodiment of the fourth invention.

FIGS. 19 to 22 show various embodiments in which the ball seat 2 has a flat plate shape. FIG. 19 is the second invention, FIG. 20 is the third invention, and FIG. FIG. 1 shows a plurality of embodiments of the fourth invention.

In using the tee-up ball seat of the present invention, as shown in FIG. 22, the inclination angle of the bottom surface 2b is changed in accordance with the change in the shot direction. The height of the tee-up may vary depending on the type of club to be used, other circumstances, etc. At this time, select one of the various heights shown in Fig. It can also be changed by embankment below the bottom 2b or by removing the soil. That is, as described below, When selecting the shape of the surface R of the ball seat surface of the image area and the direction of the image line 5 according to the preference of each player, etc., freely change the inclination angle, the inclination direction, and the height of the head of the ball support section 2b on the bottom surface 2b. This is the answer.

When the player views the golf ball from above at the time of address, the surface R of the ball seat portion of the image area is visually recognized. As described above, the shape of the surface area R of the ball seat portion of the image area changes according to the difference in the length, inclination angle, and inclination direction of the tie-up (see Fig. 23). Table 2 shows the relationship between the image areas A, B, C, and D in Fig. 23 and the ball muscles coming from the images.

Table 2

In addition, the surface area R of the ball of the image area changes depending on the preference of the player, the height of the person, the height of the person, the distance of the address (change in the relative position between the player and the ball), and the like. In addition, when image line 5 is provided, the inclination direction of the ball seat becomes clear as shown in Fig. 24 <Note that the image lines of A, B, C, D in Fig. 24 correspond to the image lines. Table 3 shows the relationship with the ball muscle.

Table 3

The image area includes, in addition to the above-described ball seat surface portion R, a ball support portion whose inclination angle with respect to the ball seat changes, but is closer to a planar view than a perspective view, that is, a position closer to the upper side of the ball ( In particular, when a person on the back approaches the ball and makes a shot), only the ball seat surface R is visible as shown in the figure, but the shape change and area change of the ball seat surface R are observed. Thus, it is possible to know the ball support state (the inclined state of the ball support portion), the distance of the address, and the like.

For the player, the psychological function (that is, the sense of security by checking the height of the ball and the inclination of the tee) has a large effect on the score, so the player should select the shape of the image area, By confirming the direction of the image line, the swing axis can be maintained in a desired state and an accurate shot can be performed.

That is, the ball seat of the present invention can be moved back and forth and left and right, not to mention the height, and can be set according to the player's preference. Also, The ability to see the image area and image lines is very important.

Industrial applicability

As described above, by using the tee-up ball seat according to the present invention, the support state of the golf ball can be confirmed by visually recognizing the image area.

In the second invention of the present application, the resistance is reduced due to the expansion of the ball supporting portion due to the elastic deformation, which contributes to an increase in the flight distance.

The third invention of the present application is based on the fact that the support portion and the ball seat portion are eccentric, and the ball support portion is tilted when the golf ball is held by the change of the image area (tilt direction, nodular angle). ) Can be visually recognized, and it is possible to always perform accurate and stable tasks with the best conditions of your choice, regardless of whether you are a tall person, a low person, or the distance between addresses.

In the fourth invention of the present application, the above-described effect of the third invention can be further enhanced by changing the image line in addition to the image area.
