Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to an artificial turf structure that can be freely tearknobbed by sticking a tippek into a desired position on a golf course teeing ground or a golf driving range. It is something.

<Prior Art> Conventional tear mats used in this type of teeing grounds or golf driving ranges are simply made up of plastic artificial turf, and rubber, plastic, etc. are placed under this artificial turf. One is constructed by integrally laminating elastic plates of Generally used were those constructed by stretching .

<Problems to be Solved by the Invention> However, among the above-mentioned prior art, there are artificial turfs, those constructed by integrally laminating elastic plates under the artificial turf, or those constructed from rubber mats themselves. etc., a small hole was made in a predetermined part of the tippek in order to stand it up, but the problem was that the places where the tipeku could be erected were limited, and the location of the tippek could not be freely selected. .

Therefore, in this case, there is a problem in that the foothold on which the club always takes a stance and the location on which the club head is hit are limited, and these locations wear out in a short period of time, making it unusable.

Furthermore, these types of artificial turf that use elastic boards or rubber mats under the artificial turf do not secure the feet sufficiently;
In addition, there were problems with boat fishing due to poor drainage, and water accumulating in the tipping area on rainy days or when watering.

In addition, when a lawn made of only artificial turf is used continuously, there is also the problem of rosinitis.

In addition, with the aforementioned structure in which the fiber aggregate is filled with sand, it is possible to puncture a golf ball by sticking a teepek in any position, but the sand filled in the fiber aggregate can be used to prevent rain or water from spraying. Sand can easily flow out, or the sand can move inside the fiber aggregate due to gravity when you take a stance, creating a hollow inside or creating uneven surfaces, making it unusable unless you repair it each time. There were other problems.

The present invention relates to a completely new technique developed in view of these problems mentioned above.

<Means for Solving the Problems> The present invention is a completely new technology that fundamentally improves the above-mentioned conventional problems. It is made up of layers of artificial grass.

<Function> Since the present invention is constructed by laying an elastic base mat made of foamed resin under the artificial turf, it is possible to tear a golf ball freely by stabbing the teepee in any desired location. I can do it.

Further, since fibers are mixed into the base mat of the artificial turf structure according to the present invention, the foamed resin base mat can be reinforced with these fibers, and in particular, its resilience can be increased. This makes it possible to prevent the base mat from being damaged even if the tippek is pierced more frequently.

Furthermore, if a thin non-woven fabric is inserted between the mat and the artificial turf, the damage to the mat can be further reduced.

In addition, when permeable holes are provided in the base mat, rainwater that has permeated the artificial turf above can smoothly flow downward through the permeable holes, thereby improving drainage of the teeing ground.

<Example> To specifically explain one embodiment of the base mat according to the present invention with reference to figures, FIG. 3 to 5 are explanatory diagrams showing the order of constructing the artificial turf structure in Figure 2, and Figures 6 to 8 are explanatory diagrams of the other side, respectively. be.

In FIG. 1, 1 is an elastic base mat,
It is constructed by mixing a large number of artificial fibers 3 into the interior of a resin plate 2 using foamed urethane having a predetermined thickness. Further, this base mat 1 is provided with a large number of water permeable holes 4 to improve water permeability.

For the foamed resin plate 2 of the base mat 1, other than the above-mentioned urethane resin, resins such as polyethylene and polystyrene can be used.

Next, an embodiment of the artificial turf structure according to the present invention will be described. In FIG. 2, a part of the ground 5 is excavated, crushed stones 6 are laid at the bottom, and the crushed stones 6 are packed and compacted. The base mat 1 is laminated on top of the crushed stone 6, and the artificial turf 7 is further laid on top of the base mat 1, and the outer peripheral edge of the artificial turf 7 is backfilled and the remaining soil 8 is pressed around the base mat 1. By fixing it, the teeing ground can be easily constructed.

The artificial grass 7 can also be bonded to the upper surface of the base mat 1 in advance using an adhesive or the like.

The order of constructing the teeing ground shown in FIG. 2 mentioned above will be explained as follows using the diagram.

In FIG. 3, a recess 9 is formed in the ground 5 by digging an area B larger than the area A of the teeing ground to a predetermined depth C upon completion. When soil drainage is poor, an underground drainage ditch 10 can be provided as necessary. Next, as shown in FIG.
Forms a crushed stone layer with a thickness of about m+. Furthermore, as shown in FIG. 5, the base mat 1 having an area A is laminated on the crushed stone layer, and then, as shown in FIG.
A teeing ground can be constructed by laying artificial turf 7 on the surface of this base mat 1, covering the outer peripheral edge of the artificial turf 7 on the outer surface of the base mat 1, and fixing it with backfilling residual soil 8. I can do it.

In the above embodiment, the area B of the recess 9 is made larger than the area A of the teeing ground, and the outer edge of the artificial turf 7 is pressed down with the remaining soil 8. When adhesively fixed to the outer surface of 1, as shown in Fig. 6,
The remaining soil 8 is completely unnecessary, and it is also possible to make the area B of the recess 9 and the area A of the teeing ground the same.

Furthermore, as shown in FIG. 7, when constructing a teeing ground on a stepped part of a slope, crushed stones 6 are laid on the stepped part without excavating the ground, and on top of that the crushed stone 6 according to the present invention is constructed. By layering the artificial turf structure and backfilling the surrounding area with residual soil 8,
It is also possible to configure the teeing ground efficiently.

In the above embodiment, the case where the entire teeing ground is constructed with one artificial turf structure has been explained, but as shown in FIG. It is also possible to construct these block-like structures and lay them in parallel on the crushed stone 6.

In the case of this embodiment, only the block-like structure damaged by use can be easily replaced, and repair is simple and maintenance is easy and inexpensive.

In the above embodiment, an example in which a teeing ground is constructed outdoors has been described, but when constructing a teeing ground in an indoor practice field, the base mat 1 and the artificial grass 7 are laminated in order on the floor surface. However, by fixing each of these to the floor surface, the structure can be easily constructed.

<Effects of the Invention> Since the artificial turf structure according to the present invention has the above-described structure and function, it is possible to freely tee a golf ball by sticking a teepek into any desired location, and therefore, it is possible to tee a golf ball at any desired location. It can create a similar feeling to the teeing ground.

In addition, unlike in the past, there is no need to tie up only in predetermined locations, so the number of stances and strokes at the same location is reduced, and the entire area can be used uniformly, greatly increasing durability. I can do it.

Since the artificial turf structure according to the present invention is elastic and has excellent restorability, punching of the club head is smooth, and the occurrence of scabitis as in the conventional art can be prevented.

Furthermore, because the base mat that is laid under the artificial turf contains a large number of fibers, it will not break even if the Tipek is inserted at a high degree of penetration, making it responsive to the Tipek's penetration. The rebound shock when you hit the club head hard is soft, giving you the feel of a natural turf, and minimizing damage from shoe spikes. Moreover, when the base mat is provided with permeable holes, it has features such as good drainage and the ability to prevent water from accumulating on the teeing ground.
