Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a detachable raised structure comprising a raised sheet such as artificial turf and a joining raised sheet that can be joined to the surface thereof.

[Conventional technology]

Synthetic fiber artificial turf in which loop-shaped piles or loop-shaped and cut-shaped piles are implanted and backed on the surface of the base material is widely known (for example, Japanese Patent Application Laid-Open No. 1973-1973).
2. Special public Sho 6O-46203).

This artificial turf is more durable than natural grass and requires no maintenance, so it is widely used in sports courts, ball fields, parks, gardens, balconies, balconies, etc. Artificial turf is generally made by backing cut piles on the surface of the base material, but in order to eliminate pile sagging and give it firmness, the piles are made into loops, or looped piles and cut piles are used. Mixed piles are also used.

[Problem that the invention seeks to solve]

As described above, artificial turf can be laid in place of conventional soil, turf, concrete, etc. to provide appropriate resilience and drainage, and although it has many advantages, it also has the following disadvantages.

That is, when many sports are played on one artificial turf athletic field, lime lines cannot be drawn.

Erasable water-based temporary paint is sometimes used in special facilities, but it is very time-consuming to apply and erase. Therefore, artificial turf is usually made and laid in a size suitable for a certain ball game or event from the beginning, and multi-purpose courts are rarely built.The tape is permanently nailed to draw the lines. Although this is possible, it would become a permanent court and would not be usable for other events.

Also, when setting up poles, it is necessary to drill holes in the grass and drive them into place.

Furthermore, when spread on a balcony or the like, the elasticity of the pile on which light items are placed makes it less stable, causing the items placed on it to topple over and, in some cases, causing items to fall off the balcony.

The present invention was arrived at as a result of studies to eliminate the above-mentioned drawbacks of artificial turf.

Therefore, the purpose of the present invention is to combine a removable sheet with a sheet having a loop pile, such as artificial turf, to draw lines on a playing field, erect gates, poles, etc., and to stabilize objects. The purpose is to provide a bondable sheet that can be placed.

[Failure to solve the problem]

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

That is, a raised sheet in which loop-shaped or loop-shaped and cut-shaped piles are flocked and backed on the surface of a base material, and a hook-like object having a length of 30 to 70% of the pile height of the raised sheet is attached or This is a removable raised structure characterized by comprising a raised joining sheet.

The raised sheet in the present invention is a sheet in which at least loop-shaped piles are attached to a base material, and artificial turf is a typical example of such a sheet.

On the other hand, a large number of hook-like objects are attached to the napped sheet for joining.
It is necessary that it be formed.

The hook-like object is preferably one in which the tip of the monofilament has a shape such as a hook shape, a fishhook shape, a T-shape, a bead shape, etc. that can be engaged with a loop-shaped pile.

The length of the hook-like material must be 30 to 70% of the pile height. In the case of artificial turf with a mixture of loop piles and cuffed piles, the height of the cut pile is usually higher than the height of the loop pile, so the hook-like material needs to be at least 50% of the pile height. Furthermore, if the hook-like object is too long, it tends to rise up, making it difficult to engage properly. Therefore, 30 to 70% of the pile height is appropriate.

In the raised sheet of the present invention, the thickness of the base material is preferably at least 111 mm or more from the viewpoint of durability and cushioning properties, and the pile preferably has a flat cross section and a ribbon shape because it is easy to get caught.

The height of the pile can be selected depending on the purpose and preference, but it is 5 to 25 f1.
The above is preferable. Therefore, the present invention is completely different from conventionally known surface fasteners.

The base material of the raised sheet for bonding of the present invention may be a simple woven fabric, or may be a layered material made of thick material. The bonding sheet is preferably in the form of a tape for use on the lines of a ball game court, etc. Also, when placing poles, flower pots, etc. on artificial turf to stabilize it, it can be made into an appropriate shape and used, for example, at the bottom of a ball stand. It can be pasted and used.

In addition, the raised sheet can be adhesively applied not only to floors, soil, concrete, etc., but also to slopes and walls. can be fixed on top of the nap sheet.

[For production]

The bonding of the bonding sheet of the present invention is based on the attachment of a loop-shaped pile and a hook-shaped object, and the principle is the same as that of a conventional hook-and-loop fastener. It is fundamentally different in that it is a hair transplant sheet.

〔Example〕

The artificial turf shown in Figure 1A was laid on a gateball field. In FIG. 1A, 1 is a base material, 2 is a cuff pile, and 3 is a loop pile. The height of cut pile 2 is 1. Oc
It was ps.

Next, the raised joining sheet shown in FIG. 1B was made into a tape shape, and lines for gateball were drawn.

The line is the joining raised sheet B and the raised sheet (artificial grass) A
It has good stability (fixed) just by placing it on the top and pressing it from above.In the joining napped sheet B, 4 is the base fabric,
is a hook-shaped monofilament with a hook-shaped end. The length of the hook-like object 5 was 6N.

In addition, the ball 7, which serves as a landmark for the stadium, can be placed anywhere on the artificial turf A by pasting the bonding sheet B on the bottom of the ball table 6 as shown in FIG.

FIG. 2 shows various examples of hook-like objects 5, including (a) to (
It was possible to implement any of the shapes of Q).

〔Effect of the invention〕

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

fl) By joining the raised sheet and the joining raised sheet, it is possible to draw erasable (removable) lines on artificial grass, which was previously impossible.

(2) Objects can be stably installed on the artificial grass.

(3) The joining sheet is removable, and in the case of line tape, it can be replaced depending on the event.
