Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple restoration type artificial lawn structure, and further to a mat for easy golf practice.

[0002]

2. Description of the Related Art Conventionally, there is a golf practice sheet consisting of an artificial lawn structure made of artificial lawn, but there is no one in which such an artificial lawn and a cushion material are joined by a hook-and-loop fastener. , There was only an artificial lawn structure consisting of a single lawn-length artificial lawn.

[0003]

In the conventional artificial lawn structure, the cushion material and the stable base are combined, and it has been necessary to prepare for a considerably high cost for restoration.
Also, since the conventional one was a wide artificial lawn structure composed of artificial lawns of the same grass length, if it was worn out and needed to be repaired, all had to be replaced, making it easy. It had a structure that could not be restored.

In view of the above-mentioned prior art, the present invention is an artificial lawn structure which is easy to repair and easy, and further has various lawn landscapes and can provide various golf environments. Also, it is intended to provide a golf practice mat.

[0005]

The present invention employs the following means in order to achieve such an object. That is, the artificial lawn structure of the present invention is an artificial lawn structure comprising a cushion material and an artificial lawn, wherein the artificial lawn and the cushion material are united via a surface fastener. The golf practice mat of the present invention is an artificial lawn structure in which one cushion material and a plurality of artificial lawns are combined via a surface fastener, and at least two different types of turf are provided. It is characterized by the presence of an artificial lawn group having a height.

[0006]

The present invention provides an artificial lawn structure and a golf practice mat that are optimal for golf practice, because they are easy to use and can produce various lawn landscapes, and in particular various golf environments can be easily designed. It was considered for. As a result, the artificial lawn and the cushion material are joined by a surface fastener, and the artificial lawn is also divided into a plurality of groups and adopted, and the cushion material that supports these is constituted by one sheet, and further, various types. We have succeeded in providing an artificial lawn structure that achieves the above effects brilliantly, by adopting a hook-and-loop fastener to construct artificial lawn groups with different turf lengths and making them removable.

As the artificial lawn of the present invention, an artificial lawn made of synthetic resin composed of ordinary base cloth and pile can be used.
For example, polyethylene, polypropylene, nylon, polyester, etc., which are commonly used, can be used.In addition, these artificial lawns can be used as white pigments, red pigments, green pigments and yellow pigments. Further, pigments colored with these mixed pigments are used, but as these pigments, pigments containing no heavy metal, such as phthalocyanine pigments, metal-containing azo pigments, titanium oxide, carbon black, iron oxide and the like are preferably used. The one colored with a pigment is preferable. Particularly in the case of artificial grass with sand, it is preferable to pay attention to the pigment in terms of environmental hygiene. A water-permeable artificial lawn can be used as the artificial lawn structure of the present invention. When such a water-permeable artificial lawn is used as an artificial lawn structure containing sand, it is necessary to provide a sand stop sheet. A non-woven fabric is preferably used as the sand control sheet, and the non-woven fabric is preferably at least 30 g / m ² , more preferably 40 to 100 g / m ² .
A range of ² is used. Such a sand stopper sheet may be provided on the surface of the artificial grass base cloth, or it may be used by being bitten by the surface fastener, that is, by being caught between the male and female surface fasteners.

The back surface of the base cloth of the artificial lawn is usually backed with rubber latex, but in the present invention, since the surface fastener is adhered to the back surface of the base cloth, the backing step is omitted when using this bonding step. You can also

As the cushion material of the present invention, a material which is usually used as a cushion material for an artificial lawn structure, for example, a rubber chip integrated with an adhesive, an elastomer foam sheet, or the like can be used. Among them, those having an Asker C hardness specified by JIS K-6301 of preferably 25 to 60 degrees, more preferably 30 to 40 degrees are preferable from the viewpoint of impact strength upon hitting and damage resistance of grass. used. From the viewpoint of adjusting the hardness, a rubber chip sheet is preferably used. The thickness of such a sheet is preferably 5 to 30 mm, more preferably 10 to 20 mm. In the case of a water-permeable artificial lawn structure, it is of course necessary to use a water-permeable cushion material, and in this case, it is preferable to use a water-permeable cushion material having a water permeability coefficient of at least 10 ^-2 cm / sec.

One such cushion material is adopted in the artificial lawn structure and the golf practice mat of the present invention. That is, a feature is that a plurality of artificial lawns are united on this one sheet through a surface fastener. When a plurality of such cushioning materials are used, a gap is generated at the seam and further a step is generated, and there is a drawback that the seam between the cushioning materials is easily disengaged, which is not practical. Therefore, in the present invention, the above problems are solved all at once by combining a plurality of artificial lawns with one cushion material via a surface fastener.

In the present invention, the artificial lawn is preferably used by separating it into a plurality of groups. By adopting this method,
We succeeded in accomplishing the repair easily and easily by simply replacing only the part of the small area that needs repair. Such a method further has an advantage that the artificial turf landscape can be changed to various ones, and accordingly, it is possible to freely produce different golf environments.

The hook-and-loop fastener used in the present invention may be one normally used, but from the viewpoint of difficulty in coming off, a base cloth,
A female or male part made of a rigid and rigid synthetic resin is preferably used. For example, a polyester fiber base cloth with hooks formed of monofilament made of polypropylene or nylon is used as a male hook-and-loop fastener, and a polyester fiber base cloth is formed with a fineness monofilament made of polypropylene or nylon to form a loop, or A non-woven fabric of such a fineness monofilament can be used as a female surface fastener. Such a surface fastener may be a female type or a male type for any of the cushion material and the artificial lawn, but preferably the male type is used for the cushion material side as compared with the artificial lawn. Since the cushioning material is used for a long period of time, it is preferable in terms of cost. That is, it is economical to use an inexpensive female surface fastener for the artificial grass in view of the disposable member. The surface fastener can be bonded and fixed using a usual rubber adhesive, urethane adhesive, epoxy adhesive or the like.
Among these, urethane-based adhesives are preferably used in terms of durability (water-resistant adhesiveness), flexibility and buffering properties. Of course, in such a surface fastener, when the artificial lawn structure is water-permeable, it goes without saying that a surface fastener having a water permeability corresponding to it is used.

The artificial lawn of the present invention has an advantage that it can be easily repaired by affixing a plurality of artificial lawns having a single lawn length as described above, but further has different lawn lengths. By attaching multiple artificial lawns,
It is possible to produce a scene that is different from the lawn scene and that is realistic. Here, artificial grasses having different grass lengths mean that artificial grasses with long grass lengths exist as a group by itself, and artificial grasses with short grass lengths exist as a group by themselves. . In other words, the long and short artificial lawns do not coexist, but they exist independently as a group in a certain area and have a difference in average grass length from the surrounding artificial lawn group. The difference is preferably 5 mm or more, and in some cases, about 10 mm or more.
The length of the turf is preferably long, preferably about 16 to 50 mm, short and about 5 to 15 mm, and is usually preferably used. However, it is desired that the length is shorter or longer than this. It can also be used appropriately depending on the sense of presence. Further, although the length and length of the turf are defined above, it is possible to use several types of short lengths at the same time, and of course, long lengths can be used in the same manner. In short, it is sufficient to reproduce a desired realistic sensation by using at least two kinds of artificial lawn groups having different grass lengths.

In such an artificial lawn group, the area occupied by the group having a relatively short grass length is large, preferably about 60 to 95% in the artificial lawn structure of the present invention, especially in the golf practice mat. Occupy a part. This is because this part mainly constitutes a stance mat and, in some cases, a shot mat. Such parts may also be composed of a plurality of artificial lawn groups and have a single turf length. The area occupied by the group having a relatively long turf length occupies the remaining area of the artificial grass group having a short turf length, but even in this case, the occupied area may be appropriately changed depending on the desired presence. it can.

The artificial lawn structure of the present invention is not limited in area as an artificial lawn structure which can be easily repaired, but as a golf practice mat, preferably about 1 to 9 m ² , more preferably 2. The tile type with a range of 3 to 4 m ² is suitable for use because it is easy to carry and store.

When the artificial lawn structure of the present invention is a sand-containing artificial lawn structure, it is possible to produce a landscape with a rich natural feel, and in the case of a golf practice mat, a more realistic presentation is provided. It has the advantage of being able to play, and also has the advantage of being excellent in the cushioning effect at the time of hitting a ball.

The present invention will be further described with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of an artificial lawn having a single lawn length of the artificial lawn structure of the present invention. FIG. 2 is a sectional view showing an example of the golf practice mat of the present invention. FIG.

In the figure, 1 and 3 are artificial grass groups having a relatively short grass length, and 2 is an artificial grass group having a relatively long grass length. In the case of this figure, the grass heights of the artificial grasses 1 and 3 may be the same or different. Of course, in some cases (depending on the desired presence, etc.), an artificial lawn with a grass length longer than 2,
Alternatively, a short artificial lawn may be used. Further, any of the groups 1 to 3 may be configured not only with one artificial lawn but also with a plurality of artificial lawns. 4 is a hook-and-loop fastener, 5
Is a female surface fastener, 6 is a male surface fastener, and these are bonded with the adhesive of 8. 7 is a cushion material. The cushion material 7 supports a plurality of artificial lawn groups with one sheet. However, in some cases, in order to enhance the natural feeling and the realism, when a wider area is required, for example, when the area exceeds 9 m ² , a plurality of cushion materials are spliced together, that is, the present invention. It is also possible to lay or connect the artificial grass structure of. Further, the artificial lawn structure of the present invention is not limited to a circular shape as shown in FIG. 3 or an irregular shape, a polygonal shape or the like as necessary, and can be changed to an appropriate shape to obtain a desired natural shape. You can create a sense of presence and realism.
