Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf ball marker used for indicating the position of a ball that has dropped onto a green of a golf course.

[0002]

2. Description of the Related Art In a game over a golf course, a flagged pole is set up in a green hole, and a competitor alternately puts on the pole with the pole as a target. When a putted golf ball falls on the green, a position such as a coin or a coin-shaped marker is displayed instead of the golf ball so that the putt of another player does not become an obstacle. Thereafter, when the turn of putting comes again, after putting the golf ball, putting is performed toward the green hole except for the coin or the marker.

[0003]

However, such a golf course is constructed so as to be rich in undulations, and usually has a complicated inclined surface on the green.
Putting into the hall is getting harder. For this reason, when putting at a place where coins or markers are placed as described above, it is necessary to grasp the inclination direction and the degree of inclination of the green as accurately as possible in order to perform accurate putting toward the hole. However, simply looking at the green sometimes gives an illusion, and it is difficult to know the details of the inclination of the green. The present invention has been made in view of the above problems, and a golf ball marker that can accurately determine a tilt direction and a degree of tilt of a green at a put position of a golf ball and perform accurate putt toward a target. It is intended to provide.

[0004]

In order to achieve the above-mentioned object, according to the first aspect of the present invention, a space for accommodating small balls in a marker body is formed in a rotatable manner. The inclination direction and the degree of inclination of the marker main body are indicated by the stationary position of the small sphere on the spherical rolling surface. Further, the invention according to claim 2 is characterized in that the spherical rolling surface is a concave curved surface in which the center side of the marker main body is the lowest. The invention according to claim 3 is characterized in that two of the small spheres are housed in the space. Also,
The invention according to claim 4 is characterized in that a display such as an arrow indicating the position of a hole in a golf course is provided in the space.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory view showing a state in which a golf ball marker according to an embodiment of the present invention is placed on a green, FIG. 2 is a plan view showing the golf ball marker, and FIG. FIG. 3 is a longitudinal sectional view taken along a line III. This golf ball marker 1
Is a space 4 formed by attaching the lid 3 to the marker body 2.
A small steel ball 8 is accommodated in the golf course B, and is used to display the position of the golf ball B dropped on the green G of the golf course shown in FIG. This golf course is constructed so as to be rich in undulation, and a green G in a peripheral portion including an area near a hole H where a pole P with a flag is set as a target of a putt has an inclined surface.

The marker body 2 has a disk shape and is provided with a spherical rolling surface 5 and a peripheral wall surface 6 on the upper side, and a leg 7 is integrally formed at the center on the lower side. The marker body 2 is made of polyacetal (Duracon) and contains 10% of an antistatic agent.
% So that it is not charged during use. The spherical rolling surface 5 is formed in a concave curved surface in which the center C of the marker main body 2 is the lowest, and has a curvature such that the small steel ball 8 rolls freely according to the inclination of the marker main body 2. The peripheral wall 6 is provided upright on the outer peripheral edge of the marker main body 2, and a step is provided on the inner peripheral edge at the upper end to form the fitted portion 6 a. Further, the leg portion 7 has a tapered shape, is easy to pierce the green G, and enables stable positioning while the lower surface 6b of the marker body 2 is in contact with the green G.

The lid 3 is a disk having an outer diameter corresponding to the inner diameter of the fitting portion 6a of the peripheral wall 6, and is formed by kneading the same antistatic agent as above into a transparent acrylic resin. (As an example, Mitsubishi Rayon Acrypet TBR-10
use). The lid 3 holds one small steel ball 8 made of steel or stainless steel on the spherical rolling surface 5 of the marker main body 2, and applies an adhesive to the fitted portion 6 a of the peripheral wall 6 before applying the adhesive. Rim 3
By fitting a, it is integrated with the marker body 2. As a result, a space 4 is formed between the marker body 2 and the lid 3, and the small steel balls 8 are rollably stored.
In this example, the golf ball marker 1 configured as described above has a diameter of about 25 mm and a thickness of 5 mm or less. Therefore, the whole is a thin disk shape,
When placed on Green G, it does not disturb Pat.

Further, this golf ball marker 1
An arrow 10 for indicating the direction of the hole H of the green G, characters indicating the inclination direction of the green G, and the like are displayed on the surface 3b side of the lid 3. Arrow 10 indicates the center C of the marker body 2
, And a thick straight line 11 extending in the diameter direction, and a thin straight line 11 orthogonal to this straight line is also displayed. further,
In order to make it easy to determine the angle with respect to the direction of the hole H, short lines 12 are marked at four positions on the spherical rolling surface 5 at equal intervals. Then, “down” indicating that the inclination of the green G becomes lower in the direction of the arrow is written at the front end of the arrow 10, and the green G is printed at the rear end of the arrow 10.
"Climbing", which indicates that the inclination becomes higher as going in the direction of the arrow. Also, on the left side of the orthogonal line 11, “Hook” indicating that the inclination of the green G is lowered leftward and the hit ball becomes a hook ball is written, and on the right side of the orthogonal line 11, the inclination is rightward. "Slice" is written to indicate that the hit ball becomes a sliced ball when it is lowered. Note that these displays may be provided on the spherical rolling surface 5 side of the marker body 2.

The golf ball marker 1 thus configured is placed in front of the golf ball B that has fallen on the green G in the golf course shown in FIG. At this time, the competitor grasps the marker body 2, stabs the leg 7 into the green G, turns the arrow 11 toward the hole H,
Push until b touches green G. Since the golf ball marker 1 has a thin disk shape as a whole, it does not move even if another player hits the ball. And
When the marker body 2 comes into close contact with the green G, if the green G is inclined, the small steel ball 8 rolls on the spherical rolling surface 5 according to the inclination and stops. At this time, if the green G is not inclined, the small steel ball 8 stops at the center because the spherical rolling surface 5 is a concave curved surface. If the position of the small steel ball 8 is, for example, the “climbing” direction on the slice side shown in FIG. 2, the inclination of the green G becomes lower to the right, and
This indicates that the vehicle is climbing up. Therefore, the competitor can easily grasp the terrain of the green G, and can make an accurate putt to the target hole H.

FIG. 4 is a plan view showing a golf ball marker according to another embodiment of the present invention, and FIG. 5 is a longitudinal sectional view showing the golf ball marker. This golf ball marker 20 is the same as the golf ball marker 1 described above.
And the basic configuration is substantially the same, only the shape of the marker body 21 is different, and two small steel balls 8 are accommodated in the space 24. That is, the marker main body 21 is
After the small steel balls 8 are arranged on the spherical rolling surface 25, the lid 3 is fitted to the marker main body 21 to be integrated. This golf ball marker 20
Also, the position is displayed on the green G instead of the golf ball B as described above.

At this time, since the spherical rolling surface 25 is flat, if two small steel balls 8 are arranged in one place, the green G
Indicates that the green G is horizontal, and when it is possible to roll away from each other to a free position, the green G is horizontal. If the small steel ball 8 is at the position shown in FIG. 4, it indicates that the inclination of the green G is rightward and that it is inclined upward toward the hole. Thus, the topography of the green G can be easily grasped by the position of the small steel ball 8,
The competitor can make a more accurate putt to the target hole H.

[0012]

As described above, according to the first aspect of the present invention, the inclination direction and the degree of inclination of the marker body are indicated by the stationary position of the small sphere on the spherical rolling surface of the space. When the golf ball is placed at the falling point of the golf ball, the terrain of the green can be easily known in the inclination direction such as hook, slice, climb and descent with respect to the target of the putt, and accurate putting can be performed. Further, since the configuration is simple, there is an effect that it is easy to manufacture. Further, according to the invention described in claim 2, since the spherical rolling surface is a concave curved surface with the center side of the marker body being the lowest, the green is horizontal when the small spherical body is located at the center of the spherical rolling surface. In addition, there is an advantage that it is easy to judge that the green is inclined when moving away from the center. According to the third aspect of the present invention, since two small spheres are stored in the space, it is possible to know that the green is inclined and the inclination direction if the small spheres are located at one place. It is possible to easily determine that the green is horizontal when it is separated, and there is an advantage that the spherical rolling surface need not be finished to a spherical surface. In the invention according to claim 4, since an indication such as an arrow indicating the position of the hole of the golf course is provided in the space, if the arrow is placed on the green toward the flagged pole, There is an advantage that the optimum putting position can be determined.
