DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf driving range ground structure which can be easily constructed, and more particularly to a surface structure thereof.

[0002]

2. Description of the Related Art As shown in FIGS. 8 and 9, a golf driving range has a ground 14 surrounded by a net 16 supported by a steel pole 15, and a ball-hitting ground 17 at one end of the ground 14. As shown in FIG.
The surface of the ground 14 is provided with alternately inclined surfaces having different inclination directions, and a U-shaped groove 9 for collecting golf balls is provided below the inclined surface. And
A golf ball 18 hit by a player from a hitting ground 17
Falls on the inclined surface and rolls on the inclined surface to enter the U-shaped groove 9. Since the U-shaped groove 9 is inclined, water flows in the U-shaped groove 9 from the collecting groove 19 provided on the side of the ground 14. It is delivered to the ball washer 20. By constructing such a driving range, it is possible to automate the collection of golf balls, and it is possible to increase the management efficiency of the driving range by saving labor.

In a conventional golf driving range, as shown in FIG. 10, a surface member 21 such as artificial turf made of synthetic resin is laid on an inclined surface of a ground 14 on which a soil ground is formed.
Also, the inclination angle of the inclined surface is set to about 3% or more to make the golf ball easy to roll.

[0004]

However, according to the above-mentioned prior art, there is a problem that it takes a lot of days even if a heavy construction machine such as a bulldozer or a shovel is used to form a slope with soil in the ground. . In addition, since a large amount of soil must be carried in from the outside to form the slope, in a densely populated area, noise and dust generated by such construction may cause inconvenience to local residents. There is.

Further, according to the prior art shown in FIG. 10, even if the slope surface made of soil is leveled so as to be a uniform plane, if the golf ball hits frequently because the surface member 21 is thin, the surface of the slope member is hit on the surface. There is also a problem that the golf ball is difficult to roll due to unevenness. Then, it is necessary to construct concrete walls on the other three side surfaces except the inclined surface so that the landslide does not occur.

Further, since the sloped surface sinks irregularly due to the own weight of the soil, or because the area around the U-shaped groove 9 easily sinks, it is necessary to repair the ground surface in order to smoothly roll the golf ball. There is a problem. In many cases, such repair work usually requires the surface member 21 to be peeled off and the soil to be reloaded and repaired. Therefore,
There is a problem that it takes time and money because new repair work occurs after the date and time after the first work.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and the first means has the same inclined surface having an inclination angle in a range of 2% to 25%. By laying and laying a plurality of inclined blocks made of synthetic resin foam on the base surface in the inclined direction in order, the surface is 2% to 25% from one side to the other side.
A lower structure having an inclined surface continuous in one direction having an inclination angle in the range of: a surface layer provided on the uppermost portion of the inclined surface of the lower structure, and a shock absorbing layer provided below the surface layer, The lower structure and the shock absorbing layer are fixed to the base surface by fixing the ends of the surface layer to the base surface.

A second means is that a waterproof layer is provided below the lower structure of the first means in addition to the shock absorbing layer.

A third means is that the surface layer is an artificial turf, the waterproof layer is a synthetic resin sheet, and the shock absorbing layer is a nonwoven fabric.

[0010] A fourth means is that the shock absorbing layer is a non-woven fabric and has a thickness of 10 to 30 mm.

[0011]

According to the first means, the lower structure is such that the inclined blocks of synthetic resin foam having an inclination angle of 2% to 25% are laid side by side on the base surface, and the surface is 2% to 25%. Since the inclined surface is a continuous inclined surface having an inclination angle within the range described above, if the inclined block is processed in advance, it is sufficient to simply assemble and arrange the inclined block on site, and the inclined surface can be formed extremely easily. The mutual connection of these inclined blocks can be performed with an adhesive, a binding device, a band-shaped member, or the like. Also, it is easy to carry in and work, and does not sink like soil.

If the inclination angle is 2% or less, the golf ball rolls poorly and stops on the inclined surface due to a slight unevenness such as wrinkles.
% Or more, the height becomes taller, so that the golf ball that has fallen to the back side when formed into a mountain shape becomes invisible, making it difficult to recognize the flight distance and increasing the amount of use of the inclined block, which is uneconomical. .

The foundation surface may be soil ground, concrete such as the roof of a building, a wooden floor, a foundation formed by arranging synthetic resin foams, or a pillar on the surface of the ground. It may be a surface such as a wire mesh or a plate material supported by the lever, and is not particularly limited. Furthermore, the base surface does not necessarily have to be horizontal, but may have a constant inclination angle.

As the surface layer, a member having an aesthetic element which looks beautiful green in the eyes of a player and having weather resistance, durability and impact resistance is selected. More specifically, artificial turf in which the turf portion is made of polypropylene and the base portion is made of polyethylene terephthalate, ethylene-propylene rubber colored in green, a soft and thick synthetic resin sheet, a nonwoven fabric, and the like are exemplified.

The shock absorbing layer serves to minimize the bouncing of the golf ball and reduce the loudness of the impact sound by absorbing the impact pressure of the golf ball. Specifically, non-woven fabric, soft urethane, sponge, rubber, glass wool and the like can be mentioned.

The surface layer and the shock absorbing layer are in close contact with the inclined surface of the lower structure.
Since the edge of the surface layer is fixed to the base surface while covering the periphery of the side surface of the lower structure, the shock absorbing layer located below it is pressed toward the lower structure, and at the same time as the surface layer, on the inclined surface of the lower structure It can be adhered without using adhesives or other members, and the lower structure can be fixed to the base surface, so even if wind load is applied or buoyancy occurs in the lower structure due to flooding It is safe.

The second means is different from the first means only in that a waterproof layer is newly provided below the surface layer. This waterproof layer is provided when the surface layer is a water-permeable member. Or, even if it is a water impervious member, if a part of the golf ball is broken due to frequent hits, it is for preventing water from entering the shock absorbing layer, and generally a synthetic resin sheet is used. used. More specifically, a vinyl chloride sheet, a polyethylene / polypropylene / polyethylene terephthalate sheet and the like can be mentioned. As a result, it is possible to almost completely prevent the shock absorbing layer from containing water, so that the durability of the shock absorbing layer is improved. Other operations are the same as those of the first means.

The third means indicates that when the surface layer is an artificial turf, the waterproof layer is a synthetic resin sheet, and the shock absorbing layer is a non-woven fabric, the most ideal golf driving range ground structure can be constructed. It is.

The fourth means indicates that when the impact-absorbing layer is a nonwoven fabric, its thickness is optimally 8 to 30 mm. Non-woven fabric is a fabric made by treating a fiber sheet mechanically, chemically and thermally and bonding it with an adhesive or the fusion force of the fiber itself. ing. Therefore, it has a certain degree of cushioning, but if it is less than 8 mm, it lacks absorption of impact sound and the bounce becomes large, so it is not very desirable as a golf driving range, but it is not enough to withstand use . On the other hand, if it is 30 mm or more, the effect of absorbing the impact sound is further increased, but the bounce becomes too small and a sense of incompatibility with an actual golf course is generated, which is not so preferable.
