2. Description of the Related Art On the greens of golf courses, depressions called ball marks or dippots are formed by golf balls falling onto the greens. Such ball marks must be repaired each time by the golfer who made the ball mark or his caddy so as not to interfere with the trajectory of the ball putt by subsequent golfers. Generally, to repair such ball marks, a repair tool called a green fork is inserted into the turf (soil) around the ball mark, and the fork-shaped tip of the green fork slightly lifts the turf around the ball mark, while This has been done by moving the turf closer to the ball mark.

However, such a ball mark repair method requires relatively skilled finger movements and is not easy for the average golfer. Furthermore, if a ball mark is repaired in this manner, the grass around the ball mark may become rough or the grass surface may become uneven. This type of turf condition is often seen when repairs are done by novice golfers, and can actually impede the trajectory of the putt ball or make it difficult for landscape managers to manage the turf. The present invention has been made in view of the above circumstances, and an object thereof is to provide a ball mark repair method and a repair tool for repairing a ball mark by inserting a repair tool around the ball mark, and to provide a golfer, etc. To provide a new ball mark repair method and repair tool which can repair ball marks easily and conveniently.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. 1 to 4 are explanatory diagrams showing a ball mark repair method according to an embodiment of the present invention, and FIG. 5 is a schematic explanatory diagram illustrating a position where a repair tool is inserted. Furthermore, FIGS. 6 and 7 are a front view and a side view showing a ball mark repair tool according to an embodiment of the present invention. As shown by the broken line in FIG. 1, when a golf ball falling in a relatively high trajectory (hereinafter simply referred to as a ball) collides with the turf surface 1 of the green, the turf surface 1 has a depression caused by the impact of the ball. That is, a ball mark 2 is formed. The ball mark 2 must be repaired each time by the golfer himself or his accompanying caddy, in order to make the trajectory of the putted ball unpredictable. In this example, in order to repair this ball mark,
A ball mark repair tool 10 as shown in FIGS. 6 and 7 is used. The repair tool 10 has a tip portion 11 with a circular cross section projecting downward, and an enlarged diameter portion 12 with a circular cross section provided above the tip portion 11, and between the tip portion 11 and the enlarged diameter portion 12. , the inclined surface 13 extends. Tip part 11, enlarged diameter part 1
2 and the inclined surface 13 are formed concentrically.
extends at an angle to the axis of the Also,
A handle 14 for gripping the repair tool 10 with fingers is provided at the upper end of the repair tool 10. The tip 11 has a spire-shaped head so that it can be easily inserted into the turf, and is formed to have a small diameter overall so that it can penetrate the turf with relatively little force. Further, the inclined surface 13 is for allowing the repair tool 10 to easily penetrate into the turf up to the level of the enlarged diameter portion 12 when inserting the repair tool 10 into the turf. It forms a smooth circumferential surface that expands in diameter. When inserted into the turf, the sloping surface 13 acts to enlarge the hole in the turf formed by the tip 11 while pressing the surrounding turf radially outward. Further, the enlarged diameter portion 12 is configured such that when this portion is inserted into the turf, the enlarged diameter of the hole is maintained.
It extends upward in a cylindrical shape. First, the tip 11 of the repair tool 10 is inserted into the approximate center of the ball mark 2, and the ball mark 2 is recessed into an approximately V-cut shape, as shown in FIG. This work has an important meaning in ensuring the successive operations of the repair tool 10. Next, as shown in Figure 3,
Insert the tip 11 of the repair tool 10 into a position slightly apart from the edge of the ball mark 2, for example, on the inclined surface 13.
The repair tool 10 is inserted into the turf until it is almost buried. At this time, the hole 3 formed by the tip portion 11 is
As shown as the hole 4 in FIG. 4, it is enlarged to a diameter approximately corresponding to the diameter of the enlarged diameter portion 12. As the hole 3 expands, the turf around the ball mark 2 is pushed toward the center of the ball mark 2, and the ball mark 2 is partially backfilled by the turf. Preferably, the repair tool 10 is inserted from outside the ball mark 2 in the direction of the axis shown by the imaginary line a in FIG. It is better to press the ball and tilt its axis slightly toward the ball mark 2, as shown by the imaginary line b. By inserting and inserting the repair tool 10 at several locations spaced apart in the circumferential direction around the ball mark 2, the ball mark 2 is formed into a so-called spike by the surrounding turf that is displaced toward the center. It becomes extremely small in diameter, about the size of a mark, and virtually disappears. In FIG. 5, the repair tool 10 is located at a location relatively close to the ball mark 2, that is, A1, A2, A3,
It is inserted into the place indicated by A4, and then the ball mark 2
Points relatively far away from B1, B2, B3, B4
It is inserted into the location indicated by . Preferably, the repair tool 10 is relatively deep at locations A1 to A4, for example,
It is inserted until the inclined surface 13 is almost buried, and at the locations B1 to B4, it is inserted relatively shallowly, for example, until the tip part 11 is almost buried. In addition, the grass around the ball mark 2 that was repaired in this way was lightly compacted with the lower end of the putter, and as a result,
It is best to level the surface of the grass evenly. The thus repaired and evenly leveled turf will return to its original state almost completely in a relatively short period of time, as the elongation of the turf leaves will naturally close the small holes left by the insertion of the repair tool 10. . As described above, in the repair method of this example, first, the center of the ball mark 2 is depressed, and the ball mark 2 is dug down in a substantially V-cut shape. This reduces the shape retention force of the turf around the ball mark 2, making it easier to displace the turf toward the center of the ball mark 2. Digging down ball mark 2 will damage the grass at the bottom of ball mark 2, but
The bottom of the dug-out ball mark 2 is buried underground in the subsequent repair process, so it does not substantially affect the growth of the turf and the uniformity of the turf surface. Rather, the pressure of the ball falling diagonally from above creates a high-density grass area and a low-density grass area at the bottom of the ball mark 2. When lifting a dense grass area with a layer of roots, it is easy to cut the roots of the grass.Moreover, the high density grass area that has been lifted to the level of the green has poor recovery power and is marked as ball mark 2. There was a problem in that marks were left on the green for a long time. In the repair method according to this embodiment, such a problem can be avoided because the grass portion at the bottom is buried underground. Furthermore, in the above repair method, the tip 11 is inserted at a position slightly apart from the edge of the ball mark 2, and the repair tool 10 is inserted into the turf to an appropriate depth. Displace the turf toward the center of ball mark 2. By performing this work at several circumferentially spaced locations around the ball mark 2, the ball mark 2 becomes extremely small in diameter and virtually disappears. In this method, a golfer or the like only has to insert the repair tool 10 into several locations on the turf to a certain depth. This is not only an extremely simple operation compared to the conventional method using a green fork, but also eliminates the risk of cutting off the roots of the grass due to improper operation of the green fork. 8 and 9 are a longitudinal sectional view and a front view showing a modification of the repair tool. The repair tool 20 of this example is used together with a tee peg (hereinafter simply referred to as a tee) used for tee shots. As shown, two tees 30 and 40 are connected. The tees 30 and 40 are commercially available tees, and are hollow with open tops. The lower end portion 42 of the tee 40 is inserted into the hollow portion 32 of the tee 30, and the tee 40
0 and is substantially integrally connected. Further, the lower end portion 31 of the tee 30 has a similar shape to the tip portion 11 of the above-described repair tool 10, and performs substantially the same function as the tip portion 11. A repair tool 20 is arranged around the tees 30, 40. The repair tool 20 is formed in a hollow shape, and the upper part of the tee 30 and the lower part of the tee 40 are concentrically housed in the hollow part. The repair tool 20 has a substantially cylindrical enlarged diameter portion 22.
and an inclined surface 23 extending downward from the enlarged diameter portion 22. The inclined surface 23 has a diameter that decreases downward, and its lower end is substantially continuous with the outer circumferential surface of the lower end 31 of the tee 30. The enlarged diameter portion 22 and the inclined surface 23 perform substantially the same functions as the enlarged diameter portion 12 and the inclined surface 13 of the repair tool 10 described above. The repair tool 20 of this example can grip the area around the head 41 of the tee 40 or the upper part of the repair tool 20. After cutting down the ball mark 2 in a substantially V-cut shape with the lower end 31 of the tee 30, the lower end 31 is inserted into a position slightly apart from the edge of the ball mark 2, and the inclined surface 23 is
Alternatively, the repair tool 20 is inserted into the turf until the lower end 31 is almost buried. Since the repair tool 20 of this example uses a tee that is easily available at a golf course, it is not only inexpensive, but also can be used as a tee for tee shots when combined with the tees 30 and 40. obtain. Figure 1
0 is a front view showing another modification of the repair tool. As can be easily understood, the repair tool 50 of this example is configured as an integrated repair tool and tee that has both the function of a repair tool and the function of a tee, and the tip portion 51 is formed by resin injection molding or the like. , the enlarged diameter portion 52, the inclined surface 53, and the tee head 55 are integrally formed. It goes without saying that the present invention is not limited to the above-described embodiments, and that various modifications and changes can be made, and these are also encompassed by the present invention within the scope of the invention described in the claims. Nor. For example, the repair tool 10 may be made of various materials such as resin, wood, or metal. Further, in the above embodiment, the intermediate surface is formed as an inclined surface and the surface of the enlarged diameter portion is formed as a cylindrical circumferential surface, but these surfaces are formed as continuous concentric curved surfaces. Also good. Further, the insertion depth of the repair tool is appropriately determined by the person performing the repair, depending on the state of the ball mark, etc.

According to the above structure of the present invention, in the ball mark repair method and the repair tool for repairing the ball mark by inserting the repair tool around the ball mark, golfers etc. can easily and conveniently repair the ball mark. It becomes possible to provide a new ball mark repair method and tool that can repair ball marks.
