DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf laid on a large floor.

[0002]

2. Description of the Related Art Artificial turf is being laid on a large floor such as a sports facility. Since these facilities are used for a variety of purposes, it is necessary to lay artificial turf according to the purpose, and as a result, the artificial turf is frequently rolled up and spread. Conventionally, artificial turf, which is simply a heavy object, is rolled up or stretched by human power or a traveling winding machine.

[0003]

In the conventional artificial turf storage and extension work, the artificial turf often drags the floor surface. Because of the high frictional resistance between the bottom of the artificial turf and the floor, this work not only requires a large amount of force, but also has a high possibility of damaging the artificial turf. Not.

[0004]

SUMMARY OF THE INVENTION The present invention reduces the frictional resistance between the bottom surface of artificial turf, which is a heavy object, and the floor surface, and performs storage and extension of artificial turf with relatively small force. The present invention relates to an artificial turf structure for preventing turf damage.

[0005] The present invention is an artificial turf having an air flow passage having a pore on the bottom surface provided on the bottom surface of the backing material and having an end of the air flow passage opened on the side surface of the backing material.

In the artificial turf of the present invention, during the storing operation or the expanding operation, the compressed air is sent from the opening on the side of the backing material and is injected through the flow passage through the pores at the bottom of the flow passage. The frictional resistance with the floor surface is reduced, and work can be performed with a small force. In particular, the stretching work is a work of finely moving the artificial turf on the bottom surface and laying it at a predetermined place, so the effect of being able to perform this work with a small force is large, especially, artificial artificial grass with a large area This is effective when winding grass.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the artificial turf of the present invention.
(A) is a longitudinal sectional view, (b) is a bottom view.

The artificial turf 1 comprises a turf section 2 and a backing material 3. As a material of the backing material 3, a hard or medium rubber or a medium or soft plastic plate or sponge is used as usual. When manufacturing the backing material 3, an elastic tubular body 4 made of a material similar to the backing material 3 is embedded in the bottom surface of the backing material 3. The tubular body 4 is disposed over the entire bottom surface of the artificial turf 1. A predetermined number of pores 5 are formed in the tubular body 4 on the bottom side of the artificial turf 1. One end of the arranged tubular body 4 is exposed on the side surface of the backing material 3 and forms an opening 8. During operation, an air discharge pipe of an air compressor (not shown) is connected to the opening 8, and air is sent from the opening 8 over the entire bottom surface of the artificial turf 1. The sent air blows out from the pores 5 and is reflected on the floor surface (usually concrete) to float the artificial turf 1. As a result, the artificial turf 1 can be moved with a small force. FIG. 1 shows an example in which one opening 8 is provided. However, several openings 8 are provided and a cover is provided. A cover at a necessary portion is removed at the time of work, and an air discharge pipe of an air compressor is connected thereto. Is preferred.

FIG. 2 shows another example of the artificial turf of the present invention.
(A) is a longitudinal sectional view, (b) and (c) are bottom views.

The artificial turf 1 comprises a turf portion 2 and a backing material 3 as in FIG. When the backing material 3 is manufactured, grooves 6 are provided on the bottom surface of the backing material 3 vertically and horizontally. The groove 6 is provided over the entire bottom surface of the artificial turf 1 and is covered with a lid 7. The material of the lid 7 is an elastic material similar to the backing material 3 and a predetermined number of pores 5 are perforated. One end of the provided groove 6 is exposed on the side surface of the backing material 3 to form an opening 8. As in the case of FIG. 1, at the time of work, the air discharge pipe of the air compressor is connected to the opening 8 and air is fed from the opening 8 over the entire bottom surface of the artificial turf 1. The sent air blows out from the pores 5 and is reflected on the floor surface (usually concrete) to float the artificial turf 1. FIG. 2B shows an example in which the grooves 6 are mainly provided in the horizontal direction, and FIG. 2C shows an example in which the grooves 6 are provided in a grid pattern in the vertical and horizontal directions. FIG.
However, although an example in which one opening 8 is provided is shown, several openings 8 are provided and a cover is provided, and a cover at a necessary portion is removed at the time of work, and an air discharge pipe of an air compressor is connected thereto. Is preferred.

[0012]

According to the artificial turf of the present invention, compressed air is sent from the opening on the side of the backing material at the time of storing work or spreading work, so that air is blown out from the pores on the bottom surface and the bottom surface of the artificial turf and the floor surface are separated. Can reduce the frictional resistance and work with a small force, and is particularly effective when working on a large area.
