Abstract

PURPOSE:To enable a golf ball to be teed up at an optional place by forming a spiral body of retainers, each of which has a side fitting groove and a projection provided on its side, in such a way as the projection of one retainer is fitted with the side fitting groove of the other retainer, and further providing erected bristles on each top of the retainer. CONSTITUTION:On the top fitting part 5 of a retainer 2 in which a side fitting groove 3 is provided on its one side and a projection 4 on the other side, a stick-like body 7 in which erected bristles have been brought into contact at the lower part is fitted. And, while the projection 4 is fitted into the side fitting groove 3 of the other retainer, the retainers 2 are rolled in a spiral shape of form a spiral body 11. Further, a hole 12 is provided in the ground, and after a plurality of spiral bodies 11 have been arranged inside the hole 12, the top parts of the retainers 2 are embedded with soil 8, and the surface of the soil 8 is made flush with the ground surface. Thus, a golf ball can be stroked with the same feeling as that when it is stroked by putting it on a natural lawn.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to artificial turf for golf use, such as on teeing grounds of golf courses.

[Conventional technology]

As conventional artificial grass for golf, there is one in which a raised surface is provided on the surface of a base material layer.

[Problem that the invention seeks to solve]

However, in such artificial grass for golf, it is not possible to insert a tee into the base material layer, and since holes for teeing up are provided in the base material layer, it is not possible to tee up at any desired location. In addition, when a golf ball is placed directly on the artificial grass for golf and the golf ball is hit, when the head of the golf club hits the base +4 layer, the head of the golf club slides on the surface of the base layer, causing the golf ball to be hit. The feeling of hitting a golf ball while placed on artificial grass is different from the feeling of hitting a golf ball placed on natural grass.

This invention was made to solve the above-mentioned problems, and it is possible to tee up at any location, and the golf ball can be hit with the same feeling as when hitting a golf ball placed on natural grass. The purpose of the present invention is to provide artificial turf for golf on which players can hit the ball.

[Means for solving problems]

In order to achieve this object, in the present invention, a side fitting groove is provided in the side part, a protrusion is provided in the side part opposite to the side part where the side part fitting groove is provided, and the above-mentioned A long holding body with a protrusion fitted into the side fitting groove and wound into a spiral shape and buried in the soil, and a long holding body provided at the head of the holding body with the upper part protruding from the soil. Provided with brushed hair.

[Effect]

In this golf artificial turf, the naps protrude directly from the ground.

〔Example〕

FIG. 1 is a sectional view showing a part of the artificial turf for golf according to the present invention. In the figure, 1 is the bottom of a hole made in the ground, 2 is a long holding body made of vinyl chloride resin, etc., made by extrusion molding, etc., and has a height of about 3G, and 3
4 is a side fitting groove provided on the side of the holding body 2, and 4 is a protrusion provided on the opposite side of the holding body 2 from the side where the side fitting groove 3 is provided. The body 2 is spirally wound with the side fitting groove 3 inside, the protrusion 4 is fitted into the side fitting groove 3, and the spirally wound holding body 2 is placed on the bottom surface 1. It is placed. 5 is a head fitting groove provided in the head of the holding body 2; 6;
is a raised rod made of resin such as nylon, and 7 is a long rod made of vinyl chloride resin or the like and made by extrusion molding or the like, and the rod 7 is fitted into the head fitting groove 5.
A nap 6 is sandwiched between the head fitting groove 5 and the rod-shaped body 7, and the nap 6 is provided on the head of the holder 2. Reference numeral 8 represents soil placed on the head of the holding body 2, and the nap 6 protrudes from the surface of ±8, and the surface of 18 is flush with the ground.

In this artificial turf for golf, the brushed turf 6 protrudes directly from the ground, and there is no base material layer on the ground unlike in the past, so it can be teed up at any location, and the golf ball can be You can hit a golf ball with the same feeling as when hitting it on grass. Furthermore, since the protrusion 4 is fitted into the side fitting groove 3, it can be easily wound around the holder 2 in a spiral shape, and the holder 2 can be wound in a spiral shape with the side fitting groove 3 inside. Since the side fitting groove 3 is wound in a closed state, the protrusion 4 can be reliably fitted into the side fitting groove 3.

Next, a method for installing the artificial grass for golf shown in FIG. 1 will be explained. First, as shown in FIG. 2, a raised element 9 made of polypropylene or the like and a weft yarn 10 are woven into a fiber body 13 in its original form, and then the fiber body 13 is woven at a position indicated by a chain double-dashed line.
is cut to form a nap 6. Next, as shown in FIG. 3, the rod-shaped body 7 is fitted into the head fitting groove 5 with the raised brush 6 in contact with the lower surface of the rod-shaped body 7. Next, as shown in FIG. 4, while fitting the protrusion 4 into the side fitting groove 3, the holding body 2 having the raised hair 6 on its head is wound into a spiral to form a spiral body 11. Next, as shown in FIG. 5, after making a hole 12 in the ground and arranging a plurality of spiral bodies 11 in the hole 12, the head of the holding body 2 is multiplied by 18, and the surface of ±8 is placed on the ground. be on the same plane as

Furthermore, when replacing the raised brush 6 of the golf artificial turf shown in FIG.
After removing the rod-shaped body 7 from the head fitting groove 5 and removing the old nap 6 from the head fitting groove 5, with the new nap 6 in contact with the lower surface of the rod-shaped body 7, insert the rod-shaped body 7 into the head fitting groove 5. While fitting into the fitting groove 5 and then fitting the protrusion 4 into the side fitting groove 3, the holder 2 was wound into a spiral to form a spiral body 11, and the spiral bodies 11 were arranged in the hole 12. Afterwards, soil 8 is poured over the head of the holder 2 to make the surface of the soil 8 flush with the ground.

In the above embodiment, as shown in FIG.
The spiral bodies 11 were arranged so that the line connecting the center points of the spiral bodies 11 in contact with the six spiral bodies 11 formed a hexagon.
As shown in the figure, the large spiral bodies 11a are arranged so that the line connecting the center points of the large spiral bodies 11a in contact with one large spiral body 11a forms a square, and the small spiral bodies 11a are arranged between the large spiral bodies 11a. The spiral bodies 11b may be arranged side by side.

〔Effect of the invention〕

As explained above, in the artificial turf for golf according to the present invention, since the raised hair protrudes directly from the ground, it is possible to tee up at any location, and the golf ball can be placed on natural turf. You can hit a golf ball with the same feeling as when you hit a golf ball. in this way,
The effects of this invention are remarkable.
