In this case, the width between the minimum circle 4d and the outer edge of the circular thin plate is half the diameter of the golf ball, so if the innermost point of the golf ball rolling on the virtual hole member 2 passes within the minimum circle 4d. A golf ball can be recognized as having fallen (cupped in) into a golf hole. It is desirable that the inner region of the minimum circle 4d and the outer region of the minimum circle 4d are colored differently. For example, the inner region of the minimum circle 4d is colored with an appropriate color such as red (minimum in FIG. 1). Coloring is indicated by adding a large number of dots to the inner region of the circle 4d), and the outer region of the minimum circle 4d can be the ground color of the thin disk without coloring). The other three circles 4a, 4b and 4c are arranged at equal intervals between the minimum circle 4d and the outer edge of the circular sheet, so the distance between the outer peripheral edge of the circular sheet and the circle 4a, the circle 4a and It is convenient that the distance between the circle 4b, the distance between the circle 4b and the circle 4c, and the distance between the circle 4c and the circle 4d are each about 5.3 mm.

The orientation setting member 16 can also be formed of an appropriate synthetic resin such as polypropylene or polyethylene, similarly to the virtual hole member 2 and the virtual pin members 10 and 12. If desired, the orientation setting member 16 can be formed from a metal such as stainless steel having a large specific gravity in terms of stability when placed in a required place. The direction setting member 18 is composed of a rectangular thin plate having a length L larger than the inner diameter (108 mm) of the golf hole and a width W smaller than the inner diameter (108 mm) of the golf hole. The length L is preferably about 180 to 220 mm, and the width W is preferably about 40 to 70 mm. A concave portion 18 having an arc shape is formed in the central portion of the direction setting member 16 in the length direction so that both end edges face each other. The curvature of the arc defining the edges of both ends of the recess 18 corresponds to the curvature of the outer peripheral edge of the circular thin plate constituting the virtual hole member 2, that is, the curvature of the outer peripheral edge of the circular thin plate constituting the virtual hole member 2. Same as or slightly smaller or larger than this. In other words, the arc defining both end edges of the recess 18 matches a part of the outer peripheral edge of the circular thin plate constituting the virtual hole member 2. The settling depth x of the recess 18 corresponds to the thickness t1 of the circular thin plate constituting the virtual hole member 2, that is, the same as or slightly smaller than or slightly larger than the thickness t1 of the circular thin plate. The thickness t2 of the regions on both sides of the recess 18 in the rectangular thin plate constituting the direction setting member 16 is a value obtained by adding 0.2 to 0.5 mm to the thickness t1 of the circular thin plate constituting the virtual hole member 2. Suitable.

As clearly illustrated in FIG. 5, it is preferable that a reference straight line 20 extending in the longitudinal direction at the center in the width direction is drawn in both side regions of the recess 18 in the direction setting member 16. The reference straight line 20 is preferably drawn by printing an appropriate color such as black or red on the surface of the rectangular thin plate constituting the direction setting member 16. The reference straight line 20 is drawn as a solid line in the illustrated embodiment, but may be drawn by other appropriate lines such as a broken line, a long-dashed line, or a two-dot chain line if desired. The center of the recess 18 in the direction setting member 16 corresponds to the outer diameter D2 of the cylinder or cylinder constituting the virtual pin member 2, that is, the same as the outer diameter D2 of the cylinder or cylinder constituting the virtual pin member 2. Alternatively, it is convenient that a circular through hole 22 having an inner diameter d2, which is slightly smaller or slightly larger than this, is formed. In order to reduce the resistance of the golf ball to rolling, if desired, the surfaces of both ends of the direction setting member 16 may be inclined surfaces that incline downward toward both end edges.

FIG. 7 shows a modified example of the direction setting member. This modification includes a pair of orientation setting members 24a and 24b. The shape of each of the pair of direction setting members 24a and 24b in the plan view matches the shape of the region on both sides of the recess 18 in the direction setting member 16. Each of the pair of orientation setting members 24a and 24b has a width W smaller than the diameter of the golf hole, both side edges are straight lines extending in parallel with each other, and one end edge is the outer peripheral edge of the virtual hole member 2. It has an arc shape that matches a part of, and the other end edge is a straight line perpendicular to both side edges. The thickness t3 of the pair of direction setting members 24a and 24b corresponds to the thickness t1 of the circular thin plate constituting the virtual hole member 2, that is, the same as or slightly smaller than or slightly larger than the thickness t1 of the circular thin plate. (See FIG. 10). Reference straight lines 26a and 26b extending in the longitudinal direction at the center in the width direction are drawn on the surfaces of each of the pair of direction setting members 24a.

Next, a usage mode of the putting practice tool including the virtual hole member 2, the virtual pin member 10 or 12, and the direction setting member 16 as described above will be described. Although the virtual hole member 2 can be used alone in the putting practice, it is desirable to use the virtual hole member 2 and the direction setting member 16 in combination as shown in FIGS. 7 and 8. In this case, the direction setting member 16 is placed in an appropriate place such as a garden of a house, a putting practice green of a golf course, or a floor of a building, and then a virtual hole member 2 is placed in a recess 18 of the direction setting member 16. Stack. In this way, the surfaces of the regions on both sides of the recess 18 in the direction setting member 16 and the surface of the virtual hole member 2 are substantially flush with each other, defining a continuous surface. The angular position setting of the virtual hole member 2 with respect to the direction setting member 16 is, for example, a specific pair of straight lines 6 drawn on the surface of the virtual hole member 2 on the reference straight line 20 drawn on the surface of the direction setting member 16. It is desirable to match the pair) that are 180 degrees apart from each other. Then, the golf ball is put on from the putting position away from the direction setting member 16 and the virtual hole member 2 by a required distance. At this time, putting is performed so as to roll on the reference straight line 20 drawn on the surface of the direction setting member 16 and toward the center of the virtual hole member 2. Then, by visually observing the trajectory of the golf ball with reference to the reference straight line 20 drawn on the direction setting member 16 and the plurality of circles 4a, 4b, 4c and 4d drawn on the virtual hole member 2. It is possible to confirm whether the hole-in was properly performed or how much the hole-in failed to deviate from the required trajectory. When the virtual hole member 2 is used alone, the golf ball can be put on with reference to any of the plurality of straight lines 6 drawn on the virtual hole member 2 (hence, a plurality of straight lines). A golf ball can be put on from a number of angular positions as defined by 6).

When it is desired to practice putting by imitating the state where the pin flag is erected in the hole, the lower end of the virtual pin member 10 is set at the center of the virtual hole member 2 as shown by the alternate long and short dash line in FIG. The virtual pin member 10 can be erected on the virtual hole member 2 by inserting it into the formed through hole 8 to practice putting. When the putting practice is performed not in the building but in the yard of the house or the putting practice green of the golf course, the virtual pin member 12 can be used instead of the virtual pin member 10. When using the virtual pin member 12, the lower end portion of the virtual pin member 12 is inserted into the through hole 8 formed in the center of the virtual hole member 2, and the tapered conical protrusion 14 of the virtual pin member 12 is virtually formed. The through hole 8 formed in the center of the hole member 2 and the through hole 22 formed in the center of the recess 18 of the direction setting member 16 are inserted into the ground, and the direction setting member 16, the virtual hole member 2 and the virtual pin member 12 are inserted. Can be locked to the ground.

The virtual hole member 2 is placed, and then the pair of direction setting members 24a and 24b are placed so that one end edge having an arc shape is brought into contact with the outer peripheral edge of the virtual hole member 2. It is convenient to arrange the pair of orientation setting members 24a and 24b so as to extend in a straight line with each other, but if desired, they may be arranged so as to form an appropriate angle other than 180 degrees. When it is desired to practice putting by imitating the state where the pin flag is erected in the hole, the lower end of the virtual pin member 10 is set at the center of the virtual hole member 2 as shown by the alternate long and short dash line in FIG. The virtual pin member 10 can be erected on the virtual hole member 2 by inserting it into the formed through hole 8.

Although the preferred embodiment of the putting practice tool configured according to the present invention has been described in detail with reference to the accompanying drawings, the present invention is not limited to such an embodiment and deviates from the technical scope of the present invention. Various deformations or corrections are possible without doing so. For example, when the virtual hole member 2 is used alone (or the virtual pin member 10 or 12 is omitted and combined with the virtual hole member 2 and the direction setting member 16) to form a putting practice tool, the virtual hole member 2 is formed on the virtual hole member 2. The through hole 8 (and the through hole 22 formed in the direction setting member 16) is a small through hole having an inner diameter corresponding to the inner diameter of the shaft main portion of a normal golf tee, and the golf tee is a through hole 8 (and a through hole 8). And through the hole 22) into the ground, thus locking the virtual hole member 2 (and the orientation member 16) to the ground.
