Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a putting green in a golf stadium and a method of forming the same, and more particularly to a putting green and a method of forming the same that can maintain the state for a long time by providing a step between the green area and the color area. .

[0002]

2. Description of the Related Art Conventionally, as a measure for clearly distinguishing a green area from others, an area called a color (hereinafter, called a color) is provided outside the green area.
Area) is provided so that the green area can be easily distinguished from the fairway.

[0003] For example, in a golf course using a natural lawn, the lawn of the land is adjusted to grow a lawn on it, and the grass in the green area is cut short and the grass in the color area is cut longer than that. The two areas are made different so that they can be distinguished. However, natural lawns are troublesome to care for, and the use of insecticides and other problems causes pollution problems. Therefore, golf courses using artificial lawns have been proposed. In a golf course that uses this artificial lawn, sand or sand-like crushed stones are laid on the artificial lawn, and the difference in the fusion color of those colors and the color of the artificial lawn is used to create a green area. It is also proposed to make it possible to distinguish it from the outer color area, or to distinguish the two areas by differentiating the length of the fluff of the artificial lawn between the green area and the color area. However, the method of laying sand or crushed stones such as sand to distinguish the two areas is expensive and not economical. In addition, since the technique of distinguishing the two areas by changing the length of the fluff of the artificial lawn is insufficient in restraining the propulsive force of the golf ball in the long fluff portion, the golf ball entering the green area It was found that the ball tends to roll out of the green area easily, which adversely affects the fun of the game. In addition, the putting green by this method has a problem that the step between the green area and the color area becomes ambiguous because the hairs are removed or worn out with use, and the repair is not easy.

[0004]

FIG. 9 is a plan view showing another putting green of the present invention. In the same figure, the putting green 1 is similar to the one shown in FIGS. 1 and 2, in which the ground is leveled, soil is piled up at an appropriate height, and an artificial lawn is put on it to form a green region 3. In addition, preferably, a member in which rod-shaped expandable polyethylene is formed in a lattice shape is spread on the soil, a synthetic fiber mat is laid on the member, and then the artificial lawn is laid on the mat.

Around the green area 3, another artificial lawn having the same length as the length of the artificial turf or the length of the artificial turf shorter than that of the artificial turf is colored. Has been formed. This collar area 10 is overlapped with that of the peripheral area of the artificial grass forming the green area 3, and nails or fastening pins are pierced through the artificial grass of the green area 3 at the required places to the laying member or soil therebelow. The artificial grass of the color area 10 is fixed by being stuck.

The color region 10 is formed by connecting a plurality of divisions of artificial lawn into a circulation body such as a circular ring or an elliptical ring, and the division body is composed of a main division body 11 and a sub division body 12. ing.

FIG. 10 is a schematic perspective view for explaining the steps of the method for forming the putting green shown in FIG. For the putting green 1, the ground is leveled, soil is piled up at an appropriate height, and an artificial lawn is placed on the soil to form a green region 3 (first step). Next, the putting green 1
About 10 m in length on the base of hard synthetic resin on the periphery of the artificial grass, which forms the green area 3.
An artificial turf having a substantially rectangular shape in which fluff of about m to 15 mm is planted is arranged as the main partitioning body 11 in a substantially annular shape (second step). The size of the main partition 11 is such that the length of one side is approximately 1 m,
The length of the other side is about 40 cm to 30 depending on the situation of the location.
It is selected to be about 0 cm.

One side of each main segment 11 is folded back at a portion about 20 cm from the end so that the fluff surface faces downward, and the boundary portion between the folded portion 13 and the non-folded portion is inside the green area (center portion). Side) so that there is no gap. Then, a nail or fastener 14 is inserted into the folded-back portion 13 located below the non-folded-back portion to fix the main division body 11 on the peripheral portion of the artificial grass in the green region 3 (third step). . Since the main partition bodies 11 are substantially rectangular, when a plurality of such main partition bodies 11 are arranged side by side in a ring shape, a gap is formed between the adjacent main partition bodies. This gap is filled with the sub section 12.

The reason why the above-mentioned gap occurs is not limited to the front side,
Since the same applies to the folded-back portion 13 side, prior to the start of the repair work on the front side, the main division bodies 1 arranged side by side
Prepare an artificial lawn piece 15 corresponding to the shape of the gap between the folded-back portions 13 and 13 of Nos. 1 and 11, and insert the artificial lawn piece 15 into the gap with the back side (non-hair surface) facing upward. Then, an adhesive tape 16 is attached to the artificial lawn piece 15 and a portion straddling the folded-back portions 13, 13 adjacent to both sides of the artificial lawn piece 15 to retain the artificial lawn piece 14 (see FIG. 11, fourth step).

At this stage, the non-folded portions of the main partition bodies 11, 11 are temporarily stretched to the completed state,
A weight is placed in the vicinity of the boundary between the folded portion 13 and the non-folded portion so that the non-folded portion can be smoothly folded back.

After a proper interval, the non-folded portions of the main divisions 11 and 11 are turned again, an adhesive (bond) is applied to the folded portions 13 and 13, and the main divisions 11 and 11 are applied. A wide adhesive tape is laid with the adhesive surface facing down on the side portions and the gap between them and the portion corresponding to the adhesive tape portion, and the adhesive is applied to the surface of this adhesive tape, and the surface of the adhesive dries. Wait for a while. When the surface of the adhesive is dried, the main partition bodies 11, 11 are again detected.
The non-folded back portion is extended and pressure is applied in the direction of arrow A to adjust the form (fifth step).

Next, a sub-section body 12 having a suitable shape (substantially triangular) for filling the gap between the main division bodies 11 and 11 is prepared and inserted into the gap between the main division bodies 11 and 11. Then, the sub-section body 12 is fixed with the adhesive on the surface of the adhesive tape (sixth step).

Next, in a portion adjacent to the main division bodies 11 and 11 and the sub division body 12, the prepared artificial lawn trousers (hairy short fibers) are sprinkled while injecting an adhesive thereto. , Making the seams of the adjacent portions inconspicuous (seventh step).

When the above steps are repeated to complete the color area, a putting green is completed. Thus, when the putting green of the present invention is used, the golf ball flying from the fairway falls to the green area 3 and rolls to the color area 4 side to reach the green area 3
When hitting a step between the color region 4 and the collar region 4, the propulsive force of the golf ball is restricted, and most of the golf balls rolling slowly stop there.

Further, since the replacement of the color area 4 can be performed easily, it is possible to promptly deal with a defect such as damage.
Further, the other end of the main division body 11 facing the folded-back portion 13 may be fixed with a fastener such as a nail.

[0025]

As described in detail above, according to the present invention, since the golf ball rolling in the green area has its driving force reduced in the color area, many golf balls deviate from the green area. Can be prevented. Therefore, the golfer can fully enjoy the satisfaction that the golf ball has reached the green area. Further, when a problem occurs in the color area, the color area portion can be easily removed and repaired, and an economically advantageous putting green can be obtained.
