Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a porous woven elastic mat with elasticity and a small surface friction coefficient, and a method of constructing a golf driving range using the porous woven elastic mat. It is.

<Prior art> A conventional elastic mat of this type is disclosed in Japanese Patent Application Laid-Open No. 61-1999.
Techniques such as those shown in Publication No. 802 or Japanese Utility Model Application Publication No. 63-57905 are known.

The former technology is an elastic material used in shock-absorbing footwear etc. in which cell elements are sandwiched from the top and bottom using liner means to form a corrugated paper-like structure, and the latter technology is an elastic material used in shock-absorbing footwear etc. that is bent into a wave or loop shape. It is an elastic body constructed in the shape of a sand inch by providing mats such as nonwoven fabric on the top and bottom of the thread.

On the other hand, natural grass, artificial grass, the above-mentioned elastic material, or foam mats such as foamed urethane have been laid in the golf ball collection spaces of golf driving ranges.

<Problems to be Solved by the Invention> However, the former of the elastic bodies according to the above-mentioned technology has the problem that the connection between the cell element and the liner means is insufficient, and the elasticity decreases when used for a long period of time. However, since the latter method simply forms a hollow part inside by waving or looping the yarn, it has problems such as being weak against compression, having poor elasticity, and having low overall strength.

Furthermore, when such an elastic body is installed in a ball collection space of a golf course, there is a rjig where the surface is damaged by the golf ball hitting it with a strong force, and the coefficient of friction of the surface is large. The golf ball does not roll smoothly, so a relatively large slope must be applied to collect the ball, and these elastic bodies also have problems such as poor drainage.

In addition, when the ball collection area of a golf practice range is made of natural grass or artificial grass, there is a problem that the grass surface is gradually destroyed by the ball hitting with strong force, causing the grass to fall off. There is a problem in which thin scratches occur on the surface of the ball when the ball makes strong contact with the turf, and especially in the case of artificial turf, the coloring agent adheres to the surface of the golf ball and stains the golf ball. was there.

In addition, if the ball collection space is constructed of a synthetic resin foam mat as described above, the foam mantle will be destroyed in a short period of time by the strong impact of the golf ball and must be replaced from time to time. Since the friction coefficient of the surface is large, the golf ball does not collect smoothly when collecting the ball, and there are also problems such as poor drainage.

The porous woven elastic mat and the construction method of the golf driving range according to the present invention relate to a completely new technology developed in view of the above-mentioned conventional problems.

<Means for Solving the Problems> The porous fabric elastic mat according to the present invention is a technology that fundamentally improves the above-mentioned conventional problems, and the gist of the first invention is that synthetic resin fibers with low heat shrinkability are used. By heat-treating a woven fabric woven by vertically and horizontally combining fibers with high heat-shrinkability and synthetic resin fibers with high heat-shrinkability, a hollow space with a bending space elastic part made of fibers with low heat-shrinkability is formed on the woven surface made of fibers with high heat-shrinkability. Filling one side of the net-like fabric with a reinforcing elastic material such as foam, latex, or thermoplastic elastomer, foaming and hardening the reinforcing elastic material, and integrally laminating the reinforcing elastic material on the outer side of one side of the hollow net-like fabric. It is characterized by a combined structure.

Furthermore, the gist of the second invention is that a woven fabric made by combining synthetic resin fibers with low heat shrinkability and synthetic resin fibers with high heat shrinkage in the vertical and horizontal directions is heat-treated to form a woven surface made of fibers with high heat shrinkability. It is characterized in that a thermoplastic resin film is laminated and integrally bonded to one side of a hollow reticulated fabric in which a bending space elastic portion is formed of fibers with low heat shrinkage.

Furthermore, the construction method of the golf driving range according to the present invention is a technology that fundamentally improves the above-mentioned conventional problems. In the ball collecting space of the field, the porous woven elastic mats described above are successively laid with joint tape between the sloped floors leveled with clay paving or the like so that the hollow reticulated fabric is on the front side. It is characterized by

Effects> The porous woven elastic mat according to the present invention is formed by combining fibers with different heat shrinkability and heat treatment to form a hollow reticulated fabric having a spatial elastic part with internal gaps, and
Since only one side of the hollow reticulated fabric is filled with foam and integrally bonded or laminated with a thermoplastic resin film, both the hollow reticulated fabric or the foam have elasticity, and the hollow Since the through-holes provided in the reticulated fabric are maintained as they are, it has good silica properties and good water permeability.Furthermore, since the hollow reticulated fabric is constructed by weaving synthetic fibers, the surface where the hollow reticulated fabric is exposed as is. It is smooth and slippery, and has low frictional resistance.

In the third invention of the present application, a porous fabric elastic mantle having the above-mentioned effect is laid in a ball collection space of a golf driving range with the exposed surface of the hollow net fabric facing up, so that the mantle elastically receives strong hits from golf balls. Since the porous woven elastic mat and the golf ball have a small frictional resistance, it is possible to prevent damage to the porous woven elastic mat and the golf ball. In particular, it prevents fine scratches on the surface of the golf ball or the adhesion of the colorant of the porous woven elastic mat to the surface of the pole.Furthermore, the golf ball rolls well, so even when the ball is on a slope with a small f. The ball rolls well, so the ball can be collected smoothly into the ball collecting groove.

In addition, the hollow mesh fabric on the front side of the porous woven elastic mat has a large number of through holes arranged in series, so rainwater and sprinkled water can flow smoothly through the through holes, allowing drainage of the ball collecting space. can be improved.

<Example> To explain the porous fabric elastic mat according to the present invention and a golf driving range using the mat according to the figures, FIG. 1 is a perspective view showing an example of the porous fabric elastic mat of the present application, and FIG.
The figure is a perspective view of the hollow reticulated fabric that makes up this elastic mat.
Fig. 3 is a perspective view of the elastic mat laid in the ball collection space, Fig. 4 is a cross-sectional view of its main parts, Fig. 5 is a cross-sectional view showing the structure of the joints, and Fig. 6 is a perspective view of the elastic mat in the middle of installation. It is an explanatory diagram.

First, the hollow reticulated fabric 1 shown in FIG. 2 is made by combining synthetic resin fibers with low heat shrinkage (polyethylene, polyvinyl chloride, etc.) and synthetic resin fibers with high heat shrinkage (polyester, nylon, vinylidene chloride, polypropylene, etc.) into warp and As the weft, the fabric is pressed by combining it vertically and horizontally at 40-150℃
The flat upper and lower line surfaces 2a and 2b are made of highly heat-shrinkable fibers, and the low-heat-shrinkable fibers are used to form the upper and lower surfaces 2a and 2b. Between 2a and 2b, spatial elastic portions 3 bent in a loop wave shape and having hollow hole-like gaps are continuously arranged in parallel.

Next, in the present invention, a reinforcing elastic material made of liquid urethane foam is injected into only one side of the hollow reticulated fabric 1 produced as described above, and then this reinforcing elastic material is dried to harden the foam. A porous woven elastic mat 5 can be manufactured as shown in FIG. 1, in which a reinforcing elastic body 4 is integrally bonded to the outer surface of one side of the hollow reticulated woven fabric 1.

Therefore, as shown in FIG. 2, in the porous fabric elastic mat 5 according to the present invention, the hollow reticulated fabric 1 is exposed as it is on the front side, and the through holes 3a are formed in the spatial elastic portion 3 of the hollow reticulated fabric l. It is provided.

The above-mentioned reinforcing elastic material can be foamed and hardened at room temperature by mixing two liquids, foamed and hardened during heat drying, or injected and hardened after hot melting, depending on the material. Thereby, the reinforcing elastic body 4 can be integrally connected to the hollow reticulated fabric 1.

In the above example, the porous woven elastic mat was constructed by integrally laminating a reinforcing elastic body such as a foam on one side of a hollow net-like fabric. A porous woven elastic mantle can also be manufactured by laminating resin films and laminating them integrally.

That is, polyethylene (PE), polyvinyl chloride (PVC
), ethylene vinyl acetate copolymer (EVA), polyvinyl (PV), or other thermoplastic resin films with a thickness of 200 to 600 microns (not shown) can be laminated and bonded together. It is.

The latter is laminated with thermoplastic resin film.
In particular, it has features such as having a waterproof effect against rainwater, etc., and being able to be mass-produced at low cost.

Next, the porous fabric elastic mat 5 constructed as described above can be used by being laid in a ball collection space of a golf driving range, as will be described later.

In FIGS. 3 to 6, reference numeral 6 denotes a ball collecting space in a golf practice range, the entire surface of which is sloped toward a ball collecting groove 7 and whose surface is paved with clay. The hollow reticulated fabric 1 of the porous fabric elastic mat 5 is laid over almost the entire surface of the ball collecting space 6 so as to face the front side. When laying the porous fabric elastic mat 5, it is laid so that the strip-shaped spatial elastic portions 3 formed in the hollow reticulated fabric 1 and the through holes 3a are parallel to the direction in which the golf ball is hit.

Further, on the back side of the connecting joints 8 of each porous fabric elastic mat 5, a joint tape 9 is provided as shown in the figure, and a cent adhesive 10 is applied along the center of this joint tape 9. The edges or both side edges of each porous woven elastic mat 5 are adhered to each other via a set adhesive 10, and after 30 to 60 minutes have elapsed after the adhesion, these porous fabrics are rolled by a roller weighing 20 to 30 kg. Fabric elastic mat 5
are firmly attached. Furthermore, the porous fabric elastic mats 5 laid in the ball collection spaces 6 of this keyaki are fixed to the alcoves with staples at intervals of 500 m5.

Therefore, the golf ball that falls into this ball collection space 6 is resiliently received by the porous fabric elastic mat 5, and then hits the surrounding net and returns to the porous fabric elastic mat 5.
The golf ball falls upward, hits the net directly from the beginning, and then falls into the ball collecting space 6, and then smoothly rolls on the porous fabric elastic mat 5 and enters the ball collecting groove 7 provided at the lowest point. The ball is automatically focused on.

<Effects of the Invention> Since the porous woven elastic mat according to the present invention has the above-described structure and function, it has high overall strength and elasticity, and the surface where the hollow reticulated fabric is exposed has low frictional resistance. ,
It is easy to slip, and since there are many through holes arranged in parallel in the hollow reticulated fabric, it has characteristics such as good water permeability.

When constructing the golf driving range according to the present invention, the porous woven elastic mat was laid over the entire surface of the ball collection space, so that the ball collection space could elastically receive golf balls that hit the ball with a strong force. This minimizes damage to the porous woven elastic mat and the surface of the golf ball, and also prevents adhesive from adhering to the golf ball.

Further, since a large number of through holes are provided in the hollow reticulated fabric of this porous woven elastic mat, the ball collection space can be drained smoothly by these holes. Further, as described above, since the hollow net-like fabric has low frictional resistance and is easy to slip, golf balls falling onto the fabric can be focused extremely smoothly to a lower direction even with a small inclination. Therefore, it is possible to reduce the overall slope of this ball collection space, thereby reducing the amount of soil to be piled up, and further reducing the hitting angle of the golf ball, which also makes the porous fabric elastic. 77 and can reduce damage to the surface of the golf ball.
