Description

Description: TECHNICAL FIELD The present invention relates to an artificial turf structure including a base material having piled hairs on its surface and a sheet structure detachably engaged with the pile.

[Prior Art] Synthetic fiber artificial turf in which loop-shaped piles or loop-shaped and cut-shaped piles are flocked and backed on the surface of a base material is widely known (for example, JP-A-57-197302, JP-B-6-62)
0-46203).

Such artificial turf is more durable than natural grass and requires no maintenance, so a sports court,
Widely used in ball fields, parks, gardens, balconies, balconies, etc. Artificial turf is generally a backing of cut piles on the surface of the base material, but in order to eliminate the fatigue of the pile and have a waist, the pile is made into a loop shape or a loop pile. A mixture of cut piles is also used.

[Problems to be solved by the invention]

As described above, artificial turf can be provided with appropriate resilience and drainage by laying it instead of conventional soil, turf, concrete, etc., and has many advantages, but has the following drawbacks.

That is, when many sports competitions are performed in one artificial grass athletic field, the lime line cannot be drawn. Erasable water-based temporary paint may be used for special facilities, but the application and erasing work is very troublesome. Therefore, usually, from the beginning, artificial turf of a size suitable for a certain ball game / competition event is often laid and laid, and a multipurpose court is rarely made. It is possible to permanently nail the tape to draw a line, but this will result in a permanent coat and will not be usable in other events.

Also, when raising a pole, it is necessary to make a hole in the grass and drive it.

Furthermore, when placed on a veranda or the like, when a light object is placed, the stability of the pile deteriorates, and the placed object may fall over, possibly causing the object to drop from the balcony.

The present invention has been reached as a result of studies for solving the above-mentioned drawbacks of artificial turf.

Therefore, an object of the present invention is to draw a line on a stadium, stand a gate or pole, and stabilize an object by combining a seat having a loop pile represented by artificial grass with a removable seat. It is to provide a joinable sheet that can be placed.

[Means for solving problems]

In order to achieve the above object, the present invention takes the following means.

That is, a sheet structure provided with artificial turf in which loop-shaped or loop-shaped and cut-shaped piles are planted on the surface of a base material, and hook-shaped objects having a length of 30 to 70% of the pile height of the artificial turf. And a pile of the artificial turf and a hook-shaped object of the sheet structure are detachably joined.

The base material in the present invention is an artificial grass in which at least loop-shaped piles are planted on the surface.

On the other hand, it is necessary that a large number of hook-shaped objects be attached and formed on the sheet structure joined to the artificial grass.
The hook-like material is preferably one in which the tip of the monofilament has a shape that engages with a loop-shaped pile such as a hook shape, a fishing hook shape, a T shape, and a ball shape.

The length of hooks should be 30 to 70% of the pile height. In the case of artificial grass with a mixture of loop pile and cut pile, the cut pile is usually higher than the height of the loop pile, and therefore the hook-shaped material requires at least 50% of the pile height. In addition, if the hook-shaped material is too long, the hook-shaped material is easily lifted up and the engagement becomes unsatisfactory. Therefore, 30 to 70% of the pile height is appropriate.

The thickness of the base material constituting the artificial turf of the present invention is preferably at least 1 mm or more in view of durability and cushioning property, and it is preferable that the pile has a flat cross section and a ribbon shape because it is easily caught. The height of the pile is selected depending on the use and preference, but is preferably 5 to 25 mm or more. Therefore, the present invention is completely different from the conventionally known surface fastener.

The base material of the artificial turf of the present invention may be a simple woven fabric, or may be a laminate of thick materials. The sheet structure is preferably tape-shaped for use in lines such as ball game courts, and when it is to be stabilized by placing poles, flowerpots, etc. on artificial turf, it should have an appropriate shape, such as the bottom of a pole stand. It can be pasted on and used.

Further, the artificial turf structure of the present invention can be adhered not only on the floor, soil, ascon, concrete or the like, but also on the slope or the wall surface. In that case, the sheet structure is used as an object. By sticking it, the object can be fixed on the artificial grass.

[Action]

The joining of the sheet structure of the present invention is based on the engagement of the loop-shaped pile and the hook-shaped object, and the principle is the same as that of the conventional surface fastener, but the one forming the loop is the pile, The point is that it is a sheet for hair transplant like this.

〔Example〕

The artificial grass shown in FIG. 1A was laid in a gateball field. In FIG. 1A, 1 is a base material, 2 is a cut pile, and 3 is a loop pile. The height of the cut pile 2 was 1.0 cm.

Next, the sheet structure shown in FIG. 1B was formed into a tape, and a gate ball line was drawn. The line was fixed with good stability simply by placing the sheet structure B on the artificial turf A and pressing it from above. In the sheet structure B, 4 is a fabric of the base material, and 5 is a hook-shaped product in which the tip of the monofilament has a hook shape. The hook-shaped material 5 had a length of 6 mm.

In addition, the pole of the stadium is artificial turf A by attaching the seat structure B to the bottom of the pole stand 6 as shown in FIG.
I was able to stand Paul 7 at any place.

FIG. 2 shows various examples of the hook-shaped material 5, but any shape of (a) to (e) could be implemented.

〔The invention's effect〕

 The removable napped structure of the present invention has the following effects.

(1) By joining the artificial turf and the sheet structure, it is possible to draw an erasable (removable) line on the artificial turf, which has been impossible in the past.

(2) An object can be stably placed on the artificial grass.

(3) The seat structure is removable from the artificial turf,
In the case of line tape, it can be replaced depending on the event.
