Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf mat such as a tee ground of a golf course and a hitting mat and a stance mat used in a golf driving range.

Most of these artificial turf mats laid on a conventional tea ground are sand-filled between piles that are concentrated in the artificial turf of the artificial turf mat having a knitted or rug structure. However, when these existing artificial turf mats are used for tee ground, the golf tee cannot be inserted directly into the woven structure, so an insertion position must be provided as a separate part. Since it is coarse, the waist is weak, and the mat itself is wrinkled or torn, resulting in a poor appearance. In the case of sand filled so that the golf tee can be directly inserted, it can be used for about 3 to 4 months. The sand between the artificial turf was compacted, and the golf tee couldn't be inserted, so it was necessary to lay the artificial turf mat again each time, which was a troublesome task.

Most of the hitting mats used in golf training fields have an elastic plate such as a rubber mat attached to the back surface of a conventional artificial grass mat, and the rubber mat on the back surface of the artificial grass mat loses water permeability. , It was not suitable for outdoor use. In addition to the elastic plate made of synthetic rubber, a hitting practice mat made by adhering a foam sponge mat to an artificial lawn with an adhesive and a mat for tea ground are also sold, but this adhesive film is water permeable The water between the piles of the artificial turf mat cannot be drained, there is a time loss until it dries and the golf tee cannot be inserted, and the sponge itself is not durable, so it is not suitable for long-term use. I couldn't stand it.

[Problems to be Solved by the Invention] The present invention provides an artificial lawn mat for golf which has excellent water permeability, cushioning properties similar to those of natural turf, and a feeling of use, and is not affected by the weather. If you can use it indoors or outdoors and lay it on the tee ground at the golf course, you can insert the golf tee at the desired position on the artificial turf mat, wrinkling due to the impact of a hard hit or the artificial grass and the cushioning material peeling off. It is intended to provide an artificial lawn mat for golf which is highly durable without fear of being damaged or broken.

[Means for Solving the Problems] In order to achieve the above-mentioned problems, the present invention is directed to a rubber layer in which rubber artificial pieces of rough artificial grass are irregularly laminated on the back surface and rubber pieces resembling the shape of a seaweed. A permeable non-woven fabric is provided between the body and the back surface of the artificial turf and the rubber pieces and the non-woven fabric are bonded and integrated by a binder, and the coarse stitches between the artificial turf and the non-woven fabric and the rubber pieces are rough. An artificial grass mat for golf with a gap formed.

In order to achieve the above-mentioned object, the present invention is a mat layer body in which a back surface of a coarse and water-permeable artificial turf, a rubber piece similar in shape to a seaweed, and foamed particles are mixed. And a non-woven fabric having permeability are provided between the artificial grass and the rubber pieces, and the nonwoven fabric is bonded and integrated with a binder, and a golf tee is inserted into the stitches of the artificial grass, the nonwoven fabric and the mat layer body. An artificial lawn mat for golf, characterized in that it has a gap to some extent.

In order to achieve the above-mentioned object, the size of the foamed particles of the artificial turf mat for golf of the present invention is 2 mm to 5 mm in diameter and the length of an elbow-shaped rubber piece is 1 c.
The mat layer has a cross-sectional area of 0.5 mm ^{2 to} 4 mm ² and the mixing weight ratio of the hijiki-shaped rubber pieces and the expanded particles in the mat layer body is at least 100: 8 to 100 :.
It is preferable that the thickness of the non-woven fabric between the back surface of the artificial grass and the mat layer body is 0.10 mm to 1 mm.

In order to achieve the above object, the mat layer body and the rubber layer body on the back surface of the artificial grass mat for golf of the present invention are integrated with a binder, and the upper layer portion in contact with the artificial grass is Providing a mat layer body formed of non-woven fabric,
It is preferable that a rubber layer body integrally formed so as to surround the bottom surface portion and the entire peripheral portion of the mat layer body is formed.

[Operation] In the invention according to claim 1, when used as a hitting mat in golf practice, a mat having a certain size for each at-bat is laid on the floor, a golf ball is placed on the mat, and the club is placed. Practice batting with
When used on a golf course, one or several mats of the present invention are spread and the mats are connected to each other, and the ends of the mats are fixed to the ground with an appropriate fixing tool such as a nail. Since a non-woven fabric having permeability is provided on the upper part of the rubber layer body made of rubber pieces in the shape of seaweeds on the back surface of the coarse artificial grass, the back surface of the artificial grass becomes strong, and the non-woven fabric and the rubber piece are formed. Improves water permeability such as rainwater in the space between them.

In addition to the striking mat and the fairway mat, according to the invention of claims 2 to 4, mats having a certain size are spread while connecting several mats according to the width of the tee ground, nails, etc. Secure it to the ground with various fixing tools. The user pierces the golf tee from the artificial grass surface through the non-woven fabric to the mat layer body in which the rubber pieces and the foam particles are mixed to make a tee shot, and the legs of the golf tee cause the elasticity of each rubber piece and the foam particles. Due to the deformation, the gap of the mat layer body is expanded, and even if the leg portion of the golf tee is sandwiched and the hand is released, the golf tee stands upright on the artificial turf.

Example 1 An example of the invention according to claim 1 will be described. An artificial lawn mat A for golf is composed of a coarse artificial grass 10 knitted by Russell knitting and a rubber layer body 15. The rubber layer body 15 is in a state in which a large number of rubber pieces 12 are laminated in an irregular direction, and the shape of the rubber pieces 12 is an elongated seagrass-like shape. The surface of each rubber piece 12 is sprinkled with a binder and solidified to form an infinite number of coarse gaps 16 between the rubber pieces 12. A permeable nonwoven fabric 13 called spun bond is provided between the back surface of the artificial grass 10 and the rubber layer body 15 to reinforce the rubber layer body 15 and the artificial grass base cloth 14. Artificial grass mat A for golf
The size is not particularly limited, but is 100 cm × 200 cm, and the thickness of the rubber layer body 15 is 2 cm to 3 cm.

The non-woven fabric 13 is made of polyester and is relatively thin and has a thickness of 0.13 mm. The material and thickness are not limited as long as they are permeable. The rubber piece 12 is carved from an old tire and has a length of 1 cm to 4 cm and a cross-section area of 0.5 mm ^{2 to} 4 mm ² , and has a length of 1.5 cm to 3 cm. About 80
%, And the rubber pieces 12 may be formed in the shape of a hijiki other than those scraped from waste such as old tires. If the artificial grass for golf mat A has water permeability, there is no particular limitation. do not do.

Example 2 An example of the invention according to claims 2 to 4 will be described. An artificial lawn mat A for golf has a coarse artificial grass 10 knitted by Russell knitting, a nonwoven fabric 13 and a rubber piece 1.
It is composed of a mat layer body 17 in which 2 and foamed particles 18 are mixed and a rubber layer body 15. The rubber layer body 15 is a state in which a large number of rubber pieces 12 are laminated in an irregular direction. The shape of the rubber piece 12 is a long and thin seaweed-shaped elbow. The non-woven fabric 13 and the rubber pieces 12 and the foamed particles 18 are bonded and integrated with each other by a binder as in Example 1, and a gap 16 is formed between the rubber pieces 12 to form a leg portion of the golf tee B. 19 is sized so that it can be easily inserted.

The base cloth 14 of the artificial turf 10 and the mat layer body 17 of the upper layer portion are integrally bonded by a binder through the non-woven fabric 13, and have a thickness sufficient to stand up by inserting a golf tee. The layer body 15 may be about ⅕ of the mat layer body 17, and the rubber layer body 15 is reinforced by bonding with a binder so as to surround the entire peripheral edge portion 20 of the mat layer body 17.

The thickness of the non-woven fabric 13 is 0.13 m.

Operation of Example The artificial grass lawn mat A for golf in Example 1 is used as a conventional mat for hitting mats or a stance mat by laying it at each bat at a driving range. Used in places and other parks. When a practitioner hits at a golf driving range, a golf ball is placed on the artificial grass mat A for golf, the stance position is determined, and even after practicing repeatedly, the elasticity of the rubber layer body 15 restores the original shape without being deformed. However, there is no risk of damaging the golf club even if a miss shot is taken due to the appropriate cushioning property. Further, the permeable nonwoven fabric 13 reinforces the rubber layer body 15 and the artificial turf base cloth 14, and rainwater also passes through the gap 16 between the coarse artificial turf 10 and the rubber layer body 15. You can expect some drainage.

When the product of Example 2 is used, the required number of artificial grass turf mats A for golf having a desired size are laid on the tee ground surface, the mats are connected, and the ends are U-shaped. Secure with nails. When performing a tee shot, the golf tee B is inserted into the artificial turf 10 and pierces through the nonwoven fabric 13 to the mat layer body 17, and the leg portion 19 of the golf tee B has the gap 16 of the mat layer body 17 and the foam particles. 18 and the rubber piece 12 can be easily inserted into a desired height by expansion due to elastic deformation, and the leg portion 19 is erected while being sandwiched in the gap 16. A golf ball is placed on the tee and hit like a tee shot made of natural grass. Also, the feel after hitting is the leg portion 19 of the golf tee B.
Is only supported between the rubber pieces 12, so there is no feeling of resistance and there is no hindrance to the tee shot. When the golf tee B is removed, the elastic deformation of the rubber pieces 12 is restored, and the gap between the stitches of the coarse artificial grass 10 is wide, so that the tee can be set at a desired position. Since the bottom surface portion and the edge portion 20 of the mat layer body 17 are enclosed and integrated by being surrounded by the rubber layer body 15, the entire peripheral edge portion is strong.

Effect of the Invention In the invention described in claim 1, since a large number of rubber pieces resembling seaweed-like hijiki are laminated to form a gap, the cushioning property may be weakened for long-term use. Without
It has excellent water permeability, so when it's raining outdoors,
Even after rain, it can be used as much as natural grass without water accumulation, and because a relatively thin and permeable spunbond is interposed, the base cloth of artificial grass is reinforced, and the stitches of artificial grass can be impacted by impact. Will not be easily damaged.

Further, the inventions according to claims 2 to 4 have a structure as described above, and therefore have cushioning properties close to those of natural grass, and a golf tee can be inserted from an artificial grass surface to easily form a mat layer body. The golf tee is supported and the golf tee can be raised to the extent that the golf ball can be sufficiently supported by its elastic force. Since the bottom surface of the mat layer body and its edge are integrally joined by the rubber layer body, there is no fear that the foamed particles and the rubber pieces will be ejected outside even if they are separated in the mat layer body by a violent striking operation. It can be used. In addition, the spun bond reinforces the artificial turf base fabric, and it is unlikely that the stitches will shift the stitches or wrinkle due to the shock of impact, and the water permeability is good as a whole, so it can be used outdoors even in the rain. It has the same feeling of use as natural turf, and once laid on a tea ground, long-term maintenance is completely unnecessary.
