Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an insect repellent net for protecting crops from insects, and more particularly to an insect repellent net for agricultural use that can be easily used in a vegetable garden.

[0002]

2. Description of the Related Art Insect repellent nets for agricultural use are formed in a sheet shape by weaving transparent monofilaments as warps and wefts.

[0003] In use, they cover plants that they want to protect from insects. That is, as in the case of tunnel cultivation, a plurality of columns having flexibility are erected in an arch shape, and an agricultural insect-proof net is put on the pillars, and the insect-proof net is fixed to the columns using a wire or the like.

[0004] However, in the insect-controlling net formed in a mere sheet as described above, since there is no configuration for fixing the insect-controlling net to the support, it is necessary to use another member such as a wire as described above. It was unsuitable for hobby use like a vegetable garden.

[0005]

SUMMARY OF THE INVENTION Accordingly, it is a main object of the present invention to provide an insect repellent net for agriculture which can be conveniently used not only in occupational agriculture but also in a home garden agriculture.

[0006] Means for that purpose is to provide an insertion portion for inserting a flexible support for extending the insect-proof net in an arch shape,
It is formed on the inner surface of the insect repellent net. The insect-proof net can be stretched by inserting the support into the insertion part, integrating the insect-proof net and the support, and inserting both ends of the support into the ground.

It is preferable that the insertion portion is formed of a floating weave. This is because the production is easy and the form of the eyes for preventing insect invasion is changed so that insect invasion is not allowed.

[0008] The insertion portion may be formed at an intersection of a predetermined position in each of a vertical direction and a horizontal direction.

Further, it is preferable that a narrow tape different in color from the monofilament be woven at a position surrounding the insertion portion. This is because the position of the insertion portion can be understood at a glance, and the operation of inserting the support post is easy.

In this case, the narrow tape is preferably an aluminum vapor-deposited tape. This is because the narrow tape reflects light brilliantly, so that a higher insect repelling effect can be obtained.

[0011] Further, a support may be inserted and held in the insertion portion. This is because, in use, it is not necessary to insert the support column, and the support can be immediately extended.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. Fig. 1 shows an insect repellent net 1 for agricultural use
Insect-proof net 1 is used in an arched manner so as to cover crops. The insect repelling net 1 has a structure in which a transparent monofilament is used for the warp and the weft, and is woven in a lattice shape so that an insect infiltration preventing eye 1a having a size capable of preventing insect invasion is formed on one surface. As shown in FIG. 2, on the inner surface, a large number of insertion portions 3 for inserting the columns 2 for extending in the arch shape are formed. The column 2 is a round bar and is formed of a synthetic resin so as to have flexibility. Insert the supporting column 2 into the insertion section 3
The insect-preventing net 1 can be integrated with the support column 2 by inserting and holding it.

Since the insect net 1 is a plain weave as described above, the insertion portion 3 may be formed at an intersection of a predetermined position in the longitudinal direction, that is, in the vertical direction, and in the width direction, that is, in the horizontal direction. 3 may be composed of a floating weave as shown in FIG.

The floating weave is plain-woven using two monofilaments for the warp yarns 4 and 5 and one monofilament for the weft yarn 6 and, at a predetermined position, one of the two warp yarns 4 and 5. It is a weaving method that does not weave. When weaving in this manner, one warp yarn 4 that is not woven is floating as shown by the imaginary line in FIG. 3, so that the strut 2 can be inserted under the warp yarn along the lateral direction of the insect-proof net 1.

By arranging such insertion sections 3 as described above, a plurality of groups of insertion sections 3 arranged in a horizontal straight line are arranged in the vertical direction. The insertion portions 3 may be formed in a straight line from one end to the other in the lateral direction, and may be juxtaposed at appropriate intervals along the length direction.

The insect net 1 thus constructed is sold singly or as a set, or as a set in which the columns 2 are inserted and held as shown in FIG.

In the installation, the insect net 1 and the support 2
Are separately inserted, the support 2 is first inserted into the insertion portion 3. Next, both ends of each column 2 are pierced into the soil so that the entire column becomes arched. This completes the installation. In the case where the support 2 is sold with the support 2 held, the operation of inserting the support 2 into the insertion portion 3 among the above-mentioned operations is unnecessary, and the support 2 is simply provided.
Stretching is completed only by piercing the soil.

When the support 2 is inserted and held in advance, both sides of the support 2, that is, portions corresponding to the outer ends of the inserts 3 located on both sides of the plurality of inserts 3 in FIG. The restricting portion 7 as shown may be attached after the insertion into the insertion portion 3. The restricting portion 7 prevents the support column 2 from falling out of the insertion portion 3, so that it does not accidentally fall off. The restricting portion 7 may be simply wound with an adhesive tape, or may be fitted with an elastically displaceable resin member having a C-shaped cross section.

In the insect net 1 constructed as described above,
Stretching work can be performed easily. When the support 2 is held in advance, the operation is further simplified. For this reason, when used in agriculture as a profession, a significant reduction in work can be expected, and even when used at home, unfamiliar work such as fixing the insect repellent net 1 to the support 2 is unnecessary, It can be easily installed by amateurs.

Further, since the insertion portion 3 through which the support column 2 is inserted is made of a floating weave, unlike the case where some member is locked to the insect intrusion prevention eye 1a, the insect intrusion prevention eye 1a is unexpectedly inserted. Since it does not spread, the insect repellent effect can be ensured.
Moreover, since only a part of the warp yarn 4 is floated, there is no bulking or snagging, and there is no support for winding, folding or spreading. Further, since the column 2 is inserted and held, the operation is extremely simple and the fixing strength is high.

FIG. 5 and FIG. 6 show an insect-proof net 1 according to another example.
The narrow tape 8 is woven so as to be a mark indicating the position.

That is, on the upper, lower, left, and right sides of the position where the insertion portion 3 is formed, as in the case of weaving a monofilament,
Narrow tape 8 slightly narrower than the width of the eyes 1a
Is interwoven so as to surround the insertion portion 3. Since the monofilament is transparent in the narrow tape 8, any other color can serve as a mark. Preferably, it is an aluminum evaporation tape. Since the narrow tape 8 extending in the vertical and horizontal directions shines in response to the sun's rays, an improvement in insect repelling effect can be expected.

[0023]

As described above, according to the present invention, the net can be stretched simply by inserting the column into the insertion portion and standing the column without using a separate member for fixing the net to the column. . For this reason, the efficiency of the installation of the insect repelling net is improved in agriculture as a profession, and there is an advantage that even an amateur can easily install the insect repelling net in home use.

Further, since the insertion portion is formed on the inner side surface, it is possible to prevent the insect invasion from being changed by changing the shape of the eye for preventing insect invasion.

Further, since the insertion portion is formed to insert and hold the column, the operation is extremely simple and the fixing strength is high.
