[Industrial applications]

 The present invention relates to an artificial turf golf course formed by knitting a knitted fabric laid on a golf course, a mini golf course, or the like.

[0002]

[Prior Art]

 As conventional uses of artificial lawns, products developed for use in playgrounds, tennis courts, parks, amusement parks, tee grounds at golf courses, and driving ranges are known. Most of these artificial lawns are made of pile fabric, and the back side of the artificial lawn is coated with an adhesive or the like to fix the pile yarn and the base cloth. The pile yarn has a cross-sectional shape of flattened or crimped to give it the appearance and feel of a natural lawn as much as possible, and a holder for setting the golf tee is fitted, and the back side is non-slip and stance. An artificial lawn with a cushioning material made of synthetic rubber etc. is used to improve the feeling. The current golf course usually consists of 18 holes, 1 hole starts from the tee ground for tee shot, fairway and green, and the distance of each course is designed as short, middle and long courses. However, a golf course in which everything from the tee ground to the green is laid with artificial grass has not been developed.

[0003]

[Problems to be solved by the device]

 Golf courses designed with natural lawns are currently a major social problem due to the use of pesticides. It takes time and labor to maintain and repair the green, and it cannot be used through all seasons. There were various problems such as the growth of turf stopped and it became necessary to do tea shots on bare ground. In addition, it takes a long time to grow lawns, it is not possible to open immediately at a new golf course, and at a golf course with a high playing frequency, the lawn is severely damaged and it is costly to maintain aesthetics, and personnel costs are also involved. It tends to increase. This invention solves the problem described by making everything from the tee ground to the green to artificial grass on the golf course, and artificial turf golf is constructed by laying the optimum artificial grass for tee ground, fairway and green. The purpose is to provide a course.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention lays a hitting artificial turf on a tea ground in which a base cloth member composed of a chain thread and an insertion thread is provided with a number of spaces having a size for inserting a golf tee. The putter artificial turf is arranged on the green by arranging more than the number of chain threads in 1 inch of the turf and knitting the space part with a small diameter, and the artificial turf of either the hitting artificial turf or the putter artificial turf is faired. The artificial turf golf course is characterized by being laid on a way. In order to achieve the above-mentioned object, in the denier of pile yarn which is a flat false yarn entwined with chain yarn, the pile yarn bundle of the hitting artificial grass is 3000 to 7500 denier, and the pile yarn bundle of the putter artificial grass is 1500. It is preferably characterized in that it is in the range of ˜5000 denier.

[0005]

[Action]

 In the invention of claim 1 described above, the chain thread and the insertion thread of the hitting artificial grass are knitted in a mesh shape, so when they are spread on the tee ground, they are in close contact with the surface of the soil surface, and a size that allows the golf tee to be inserted. In addition, by forming a space part, the expansion and contraction action in the vertical and horizontal directions does not significantly affect the unevenness of the soil surface, and it is possible to spread without slack or wrinkles. Also, since the number of chain threads provided in the vertical and horizontal 1 inch of the putter artificial grass is larger than that of the hitting artificial grass, the space becomes narrower and the pile threads are used to prevent the growth of weeds from the soil surface. The putter artificial grass with higher density is knitted by bundling relatively thin flat yarns of denier for use on the green.

According to the second aspect of the invention, the pile yarn bundle of the hitting artificial turf in the tea ground is set to a denier number that can withstand the momentary impact strength during repeated tea shots. It is limited to the denier range where you can putter with a green feel on natural grass.

【Example】

 Now, a typical embodiment including the invention described in all the claims will be described with reference to the drawings. FIG. 2 is a perspective view showing a short course of a golf course. An artificial turf A on the tee ground, an artificial turf C laid on the fairway, and a putter artificial turf B laid on the green are connected to each other. It constitutes a turf golf course. The hitting artificial turf A laid on the tee ground is a knitted fabric knitted like a warp knit, for example, an artificial turf 2 composed of a Russell knitted fabric. The chain yarn 5 which is a warp yarn is 3 in 1 inch. The pile yarn 3 knitted into 6 pieces, which is a single piece, is entangled with the chain thread 5 and made upright so that the length of the pile thread 3 is 10 to 18 mm, and the size of the space portion 6 of the base cloth member a. The size is such that the golf tee can be easily inserted into any place. Since the number of single pile yarns is 500 denier, and 12 yarns, the pile yarn bundle 3 has a thickness of 6000 denier or more and a thickness capable of withstanding a tee shot impact. As the material of the artificial lawn 2 of the present invention, polypropylene, polyethylene, polyvinylidene chloride, etc. can be used in addition to nylon 6 and nylon 66. However, nylon 66 is used for the purpose of use. The putter artificial turf B laid on the green is knitted so that the number of chain threads 5 is 6 in 1 inch and the number of insertion threads 4 is 8 and the length of the pile thread entwined with the chain threads 5 is upright. It is finished to 8 to 15 mm, and the size of the space portion 6 of the base cloth member a is formed to such an extent that the weeds on the soil surface are difficult to grow. The raw material of the artificial turf 2 has a width of 1 to 2 m and a length of about 20 m, which is rolled up and laid out in the striking direction, and the width direction is joined by sewing thread or double-sided tape. To A U-shaped groove is provided near the boundary 7 between the slope of the tee ground and the fairway surface, and a U-shaped member having a length of 60 cm and a diameter of 12 cm is fitted in the U-shaped groove in the width direction. , The end of the artificial grass C for fairway on the side of the inclined surface 9 is pushed into the U-shaped member and fixed with concrete timber, and then the end of the artificial artificial grass A is laid on the inclined surface 9 in the direction of the fairway. The part is made to cover the top surface of the concrete timber and connected and fixed with nails or the like.

The rough portions 10 on both sides of the fairway may be made of natural grass or artificial grass with a long pile thread, and the ends of the artificial grass in the width direction such as both sides of the fairway are fixed with nails or concrete. Stretch it with timber. Also, in places where there is a risk of wrinkles or slack in the artificial lawn due to the topography such as the mini course or the large laying area, both the tee ground side and the fairway side should be fixed before and after the impact direction. Part of the lawn will be fixed while adjusting the tension. The putter artificial turf B laid on the green is cut into a substantially circular shape and joined to the end of the artificial turf C for fairway, and the periphery is provided with a collar portion and fixed by the method described above. Golf course 1 is completed. In the new tee ground, an inclined surface 9 is provided by embankment, crushed stone dust is used on the surface of the soil surface, and crushed stone is formed in the lower layer to form a structure with good drainage. Since 2 itself is permeable, it does not affect play. In the conventional tee ground, the soil surface should be constructed so as to have the above structure, or the back surface of the artificial turf A with adhesive applied should be dot processed or an underpad should be placed between the soil surface and the artificial back surface. It can be laid out so that it will not interfere with play even in the rain. In this invention, artificial turf A, B and C are laid from the tee ground to the green, but for example, it can be laid in a hole that seems to be necessary out of 18 holes, or when the lawn grows poorly or is used. Since it is possible to freely design the entire golf course, such as holes that are frequently damaged and where natural grass is severely damaged, we can expect to create a unique golf course that has never existed before.

[0009]

[Effects of the Invention] In the invention described in the claims which is constructed and operates as described above, the hitting artificial turf for tee ground is convenient because the golf tee can be set up at any place. Has the effect of obstructing the growth of weeds, eliminating the need for maintenance and repair of the green altogether.Because it consists of artificial grass from the tea ground to the green, there is no need for pesticides to control pests and pesticides. The problem has been resolved, the turf growth has stopped in winter, and the discomfort of shooting on bare terrain has disappeared, making it possible to enjoy full-season golf throughout the year. In addition, artificial turf has a lower total cost than natural turf, and at the newly established golf course, you can expect an economic effect that you can open it immediately without waiting for the lawn growing period. Also, if there is a part where the artificial turf must be replaced due to long-term use, it is possible to easily repair it by digging in the concrete corner member that holds the replacement part and fixing it again.
