Description

[Detailed description of the invention] This invention relates to a protective netting suitable for agriculture, forestry, horticulture, buildings, sports facilities, etc., especially as a bird net that is spread over agricultural crops and fruits to prevent bird damage. It is something.

Bird nets have the function of either acting as an obstacle to prevent birds from entering, or intimidating birds from approaching by swaying in the wind or reflecting light, causing birds to get caught and become violent. In order to prevent damage such as damage to agricultural crops and fruits, to make it lighter and to make the covering work easier, and to be economical in terms of manufacturing the netting, we used Gokai gun fat film and made cuts. Increasingly, it is made of something that becomes net-like when stretched out, or something that is knitted into a flat thread.

However, such bird nets that are mainly made of synthetic resin film lack mechanical strength and are particularly prone to tearing and breaking the mesh, so they cannot be stretched under tension, and removal work is troublesome, making them difficult to handle. .

Furthermore, even if the bird net constructed by knitting monofilament yarns or twisted yarns is reinforced at the periphery and stretched out, loosening in the center cannot be avoided.

By the way, what is important for bird-prevention nets is that the entire net is stretched out under moderate tension and maintained in a square shape.By stretching the net so that it is square and without loosening, the entire net has elasticity. This gives the thread a strong sway, making it more intimidating when it sways in the wind, and eliminates the inconvenience of the thread becoming tangled and caught when a bird comes into contact with it.

This project can meet these demands, and in addition to protecting crops and fruits from bird damage, it also encloses farmland, orchards, and forested areas to prevent intrusion of animals, or covers buildings to protect them from bird damage caused by pigeons, etc. The purpose of this invention is to provide a mesh fabric that can be widely used for protection, such as preventing accidents and also surrounding sports facilities to prevent danger. Examples thereof will be described below with reference to the drawings.

In the drawings, the main body mesh portion 1 is formed by knitting relatively thin threads, preferably monofilament yarns of synthetic resin, as the warp and weft, and has a plurality of threads, for example two threads, at both ends extending in the vertical or horizontal direction. By knitting relatively thick twisted yarns in place of the warp or weft of the main body mesh part 1, edge reinforcement mesh parts 2, 2 are formed.
At the same time, a plurality of relatively thick twisted yarns, for example three, are knitted in place of the warp or weft of the main body fabric part 1 at a location extending in the vertical or horizontal direction and dividing the main body fabric part 1 into three equal parts. By inserting two intermediate reinforcing mesh portions 3, 3,
These three types of mesh portions 1, 2, and 3 form a mesh main body 4.

Supporting filaments 5 made of relatively thick twisted yarns run along the four edges of the net fabric main body 4. 5.6.6 are read through, and fixing devices 7 made of metal rings, hooks, etc. are attached to the four corners and both ends of the intermediate reinforcing mesh portion 3.3.

The supporting filaments 5, 5° 6.6 are equal in length to the mesh main body 4 when stretched so that the mesh becomes a square, and both ends thereof are tied to the edge reinforcing mesh portions 2, 2, Further, the supporting filaments 5, 5 threaded along the edges not having the edge reinforcing mesh portions 2, 2 are tied to the intermediate reinforcing mesh portions 3, 3.

The mesh fabric of the present invention constructed in this way is stretched and fixed by stretching each of the supporting filaments 5, 5, 6.6 linearly in the longitudinal and lateral directions so that the mesh becomes square. The tool 7 is fixed by being hooked onto a support, tree branch, etc.

In addition, the supporting filaments 5, 5, 6, 6 are connected to the edge reinforcing mesh portions 2, 2.
Alternatively, the filaments 5, 5 may be made of rope, wire, etc., which are first tensioned and fixed, and the net fabric main body 4 is stretched and threaded or wired. Sometimes they are tied together with string.

Furthermore, the mesh main body 4 can be arbitrarily joined vertically and horizontally by using the edge reinforcing mesh portion 2 and the supporting filaments 5, 5, and can be cut at the intermediate reinforcing mesh portion 3. It is possible to change the overall size and shape depending on the place of use, and furthermore, the intermediate reinforcing mesh portion 3 can be used as it is as the edge reinforcing mesh portion without cutting, and the surplus portion on the outside can be used as it is. It is also possible to use it by folding it appropriately.

In addition, edge reinforcement netting portions 2, 2,
The supporting filaments 5, 5 can be fixed by tying them with thread or string.

As described above, the present invention is constructed by knitting relatively thin yarns such as agglomerated gun fat single fiber yarns, and a plurality of relatively thick twisted yarns are placed at both ends and intermediate positions extending in the vertical or horizontal direction of the main body netting section. A reinforcing mesh section formed by knitting is provided, and the supporting wires are passed through at least the edge of the main body of the mesh extending in a direction orthogonal to the reinforcing mesh section. By pulling the supporting filaments in a straight line and tightening and fixing them, the main body of the net is stretched as it is, and the intermediate reinforcing net fabric part is stretched by the supporting filaments at both ends and becomes tense.
For this reason, the main body mesh part, which is made of thin threads and tends to loosen, is stretched under moderate tension to maintain the mesh in a square shape.

Therefore, when used as a bird-prevention net, the main body of the net is given appropriate elasticity, and even the slightest breeze causes it to sway and ripple, creating a sufficient frightening effect on birds. Since it does not stain, there is no need to worry about damaging crops or fruits, and it is highly effective.

In particular, the present invention provides fixing devices at the four corners of the netting body and at both ends of the intermediate reinforcing netting portion, which not only allows the rope to be easily fixed and stretched to branches, but also prevents loosening of the main netting portion. In addition, the intermediate reinforcing mesh portion helps to prevent this and maintain the mesh in a square shape when it is stretched.

In addition, the reinforcing netting at both ends and the middle, and the supporting wires passed through the edges perpendicular to these, make it easy to extend and remove the netting, and the netting itself can be positioned accurately. In addition to netting, it can also be used for agricultural purposes such as covering seedbeds, etc.
Furthermore, it can be used in forestry to eliminate birds and animals, and is suitable for preserving buildings, civil engineering works, sports facilities, etc., and can also be used for fishing purposes, such as seaweed or gear cultivation equipment, or fishing nets.
