Description

[Detailed explanation of the idea] [Industrial application field]

The invention is used in the field of agriculture and forestry. More specifically, bird prevention installed in orchards, etc.
Of the nets and cheesecloth used for insect control, frost protection, sunshade, heat retention, etc., it is especially used as a protective net for ceilings. The present invention relates to a protective net.

[Prior art and its issues]

Attempts have already been made to cover entire orchards with protective netting to prevent bird and insect damage. Among conventional protection nets, the ceiling protection net was placed in the orchard, and the net was opened and closed by pulling the net while it was placed on the fruit tree shelf. For this reason, when plants protrude from the surface of the fruit tree shelf, the net has the disadvantage that it can get caught on the protrusions or the plants, causing damage to the net. The inventor has already filed a patent application regarding this issue in 1982.
In No. 110611, we proposed a method and device for opening and closing a protective net, and solved the above problems. By the way, because the areas where orchards and the like are grown are vast, there is a limit to the area that can be covered by one protective net. In addition, a huge amount of capital investment is required to manufacture a large, one-piece protection net. Therefore, rather than manufacturing a vast single-piece protection net, it is better to create a protection net of the required width and shape by joining a required number of appropriately sized mesh pieces. The requirements for a protective net include reducing the overall weight of the net, making it less susceptible to wind resistance, opening the net wide enough to prevent insects from entering, and making the threads as fine as possible as strong as possible. It is capable of withstanding natural forces such as wind and rain for a long period of time.
A synthetic resin net can be cited as a material that satisfies this condition. However, since the threads of the synthetic resin net are as fine as their strength allows, they lack strength when pulling or lifting the edges.
The disadvantage is that the net will tear from the edges when opening and closing or on windy days. A possible solution to this problem would be to wrap the edges and lifting parts of the net with cotton cloth or synthetic resin sheets to reinforce them. However, in the case of cotton cloth, if it contains moisture, it will shrink during drying and will not fit the original dimensions, and the mesh will not only not close completely, but will also tear at the perforations and eyelet holes. Furthermore, in the case of synthetic resin sheets, problems remain in terms of strength.

[Purpose of invention]

Therefore, an object of the present invention is to provide a protective net that can obtain the required width and shape by connecting a required number of mesh pieces of appropriate width. Another object of the present invention is to provide a protective net that has sufficient strength even when lifted or stretched.

[Structure of the idea]

The structure of the present invention taken to solve the above problems is as follows. That is, in the present invention, a main rope is strung between the pillars that are erected through the joints of the mesh pieces, and the main rope is suspended from the main rope and lifted from the shelf on which it is placed when opening and closing. A protective net that is opened and closed after the net is opened and closed, in which a synthetic resin net is used as the net member, one piece or a required number of the net members are joined to form the net piece, and the net piece is attached to the required number of net pieces via a fastener. A number of sheets are joined together to form a protective net with a shape that matches the area to be protected, and the protective net is provided with a required number of reinforcing parts from one end to the other, and the reinforcing parts are more visible than the net members. A fine synthetic resin reinforcing net is bent into an inverted U shape so that the reinforcing rope is wrapped inside the bent part, and a part of the net member is overlapped and sandwiched between both sides of the reinforcing net, so that the reinforcement The protective net is attached integrally with the net, and further has hanging holes provided at appropriate intervals in the reinforcing portion.

【Example】

The present invention will be explained in more detail based on embodiments shown in the drawings. Figures 1 and 2 are shown. In the figure, protection net 1
uses a mesh woven net. A nodule mesh can also be used, but this is not preferred because the raised areas of the nodules will wear out and become weak. The protective net 1 is made of a synthetic resin net with a mesh that prevents insects from entering. The protection net 1 is formed by joining a required number of mesh pieces 2 via fasteners 3 and having a required width and shape in accordance with the area to be protected. The mesh piece 2 is formed by joining one or a required number of mesh members 21 together. Figures 2 and 3 are shown. A required number of reinforcing ropes 4 are attached to the joint 25 where the net members 21 are joined from the end A to the end B of the protective net 1, thereby providing a reinforcing part 5. As shown in the figure, the reinforcing rope 4 is used to reinforce the lifting part when the protective net 1 is lifted from the fruit tree shelf by the main rope 8, and as shown in FIG. The ends of the net member 21 to be joined are each raised up, and a reinforcing net 51 having a finer mesh than the net member 21 is bent into an inverted U shape to form a bent portion 50. And the bending part 50
The reinforcing rope 4 is arranged so as to be wrapped in the reinforcing rope 4, the end of the net member 21 is sandwiched between the both side pieces 52 and 53 of the reinforcing net 51, and the end of the reinforcing net 51 and the net member 21 are tied together with the thread 1.
It is sewn with 0. A required number of eyelets 6 are attached to the reinforcing portion 5. A hanging fitting 7 is attached to the eyelet 6, and a protective net 1 is installed.
is attached via a hanging fitting 7 to a main rope 8 which is provided so as to be tensionable and loose. In addition, when the fastener 3 is attached to the mesh piece 2, as shown in FIG. 5, a reinforcing net 51 is interposed between the fastener 3 and the mesh piece 2 for reinforcement.
Further, a reinforcing net 51 is sewn around the protective net 1 so that it will not be torn even if the protective net 1 is pulled. Supports 9 are arranged on the end A and end B sides of the protection net 1 in the joint 25 to support the main rope 8. In this case, in order for the protection net 1 to completely cover the protected area, the end A of the protection net 1 of the joint part 25,
The fastener 3 is attached without joining the vicinity of the end B, and the fastener 3 is closed so as to surround the support column 9. When using the present invention, as shown in FIG. 2, the main rope 8 is stretched around the support 9 so that it can be stretched or loosened freely, and the protective net 1 is stretched over the protected area. When protecting fruit trees in a protected area, as shown in FIG. 2, the net pieces 2 are joined with fasteners 3 and the protective net 1 is placed on the fruit tree shelf. When opening the protection net 1, the main rope 8 is stretched, and the protection net 1 is lifted from the fruit tree trellis, and then the fastener 3 is opened and the tow rope 8
1 to draw the net pieces 2 to the corners to open the protection net 1, loosen the main ropes 8, and place the protection net 1 around the orchard.

[Effect of the idea]

The present invention produces the following effects. (1) The protection net is formed by joining the required number of mesh pieces via fasteners and forming the required shape according to the area to be protected, and the mesh piece is formed by joining one piece or the required number of net members. Therefore, a protective net of the required width and shape can be easily created. (2) The protective net is provided with the required number of reinforcing parts from one end to the other, and the reinforcing parts are made by bending a synthetic resin reinforcing net finer than the protective net into an inverted U shape. The reinforcing rope is wrapped in the bent part, and a part of the net member is overlapped and sandwiched between both sides of the reinforcing net, and is integrally attached to the reinforcing net. Hanging holes are provided at intervals. Therefore, even if the protective net is lifted, it will not be torn at the lifted point. Furthermore, since the mesh can be sewn without cutting, the strength of the reinforcing portion is improved.
