Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for fences installed along roads for the purpose of windproofing, snowproofing, sandproofing, etc., or on farms, forests, wilderness, golf courses and other places with a lot of undulating slopes. The present invention relates to a net for a fence, specifically, a net for a fence in which the net is formed by a belt.

[0002]

2. Description of the Related Art Conventionally, there is a fence net in which a synthetic resin belt is formed in a lattice shape or a cage shape. In this net, a large number of belts are arranged in parallel at regular intervals, and several belts are arranged at right angles to these belts in parallel at regular intervals to fix the intersections by welding.

[0003]

When installing fences, when extending from a horizontal ground to an uphill or downhill slope, lateral belts are diagonally arranged in parallel at regular intervals along the angle of the slope. In contrast to the laterally sloping belt, the vertical belts are arranged in parallel at a constant interval to the pillars standing on the sloping ground, so the vertical and horizontal belts do not intersect at a right angle, The angle at which the vertical and horizontal belts intersect at the intersection differs depending on the angle.

However, the conventional net cannot be used on a sloping ground because the intersections of the vertical and horizontal belts are welded and fixed, and on the sloping ground, the angle at which the vertical and horizontal belts intersect differs depending on the inclination angle. I had to prepare another net.

In view of the above points, the present invention makes it possible to arbitrarily and easily change the crossing angle at the intersection of vertical and horizontal belts forming a net stretched between adjacent stanchions. The purpose is to provide a fence net that can be used.

[0006]

In order to solve the above problems, the fence net of the present invention according to claim 1 is a fence in which a net formed by a belt is stretched between adjacent struts. It is characterized in that the belts are crossed in the vertical and horizontal directions, and the vertical and horizontal belts can be crossed at any angle at this crossing portion.

With such a structure, the vertical and horizontal belts forming the net can intersect at an arbitrary angle at the intersection. Therefore, when the belts are stretched between horizontal columns, the vertical and horizontal belts should be crossed at right angles. Further, when it is stretched between the columns of the sloping ground, it is possible to cross the vertical and horizontal belts at an intersection angle corresponding to the inclination angle of the sloping ground, and therefore, it can be used for both horizontal and sloping grounds.

Next, a fence net according to a second aspect of the present invention is the fence net according to the first aspect, in which an opening is provided in either the vertical or horizontal belt at the intersection, and the other opening is provided in this opening. The belt is inserted through. With such a configuration, the other belt is merely inserted into the opening portion of the one belt and is not fixed, so that the vertical and horizontal belts can intersect at an arbitrary angle at the intersecting portion.

Next, the fence net according to a third aspect of the present invention is characterized in that, in the fence net according to the first aspect, vertical and horizontal belts are rotatably fixed at intersections. . With such a configuration, the vertical and horizontal belts can intersect at any angle at the intersection.

Next, the fence net of the present invention according to claim 4 is the fence net according to claim 1, 2 or 3, wherein the belt is formed of synthetic fibers, natural fibers, or a combination of synthetic fibers and natural fibers. It is characterized by being present. With such a structure, the belt has tensile strength as compared with a belt made of synthetic resin.

Next, the fence net of the present invention according to claim 5 is characterized in that, in the fence net according to claim 4, a light emitting thread or a fluorescent thread is used for a part or all of the belt. is there. With such a configuration, the presence of the net can be easily confirmed even at night.
