Description

[Detailed description of the invention] [Industrial field of application] This invention is a knotless fishing net used for netting or trawl nets, etc., and is a 4-penetration type net made by intersecting two strands of string coming from different directions. The present invention relates to a knotless fishing net having a tortoise shell-shaped mesh having a penetrating portion formed therein.

[Conventional technology]

Conventionally, in this type of knotless fishing net having four penetrating portions, each string intersects while being twisted to form the penetrating portion. In other words, in order to form a predetermined mesh, two twisted strings approach each other while being twisted from different directions.
Each string intersects to form a penetration part, and as the strings are further twisted, they form the next penetration part with other strings, thereby sequentially forming a mesh.

In this case, the penetrating part is only one twisted loop formed by one two-stranded string, and the other two-stranded string intersects and penetrates, and the penetrating part is formed in all directions from the penetrating part. It is held in place by the twisting of the yarn legs.

[The problem that the idea aims to solve]

If the structure of the penetration part is as in the conventional example, when a load such as splitting is applied to the mesh, the penetration part easily shifts against the twisting of the yarn legs, and the shift is not restored. Therefore, not only does a tension condition occur and the net formation deteriorates, but if one of the two-stranded strings breaks, the penetrating part itself has no holding power, so it easily loosens and slips out, which can lead to infection. However, the other penetrating portions also have the problem of being easily loosened and displaced.

[Purpose of invention]

The present invention was devised to eliminate the problems of the conventional example, and its purpose is to provide a holding force to the penetrating part itself to prevent misalignment, and to prevent one string from breaking. It is possible to form a penetration part of a predetermined length, making it difficult to escape from the penetration part even when
It is an object of the present invention to provide a knotless fishing net having a tortoiseshell-shaped mesh as a whole.

[Structure of the idea]

The present invention was made to achieve the above purpose.
In a knotless fishing net in which the mesh is constructed by intersecting two strings each coming from different directions to form a four-through type penetration part, each two-strand string is twisted in the penetration part.
The real twisted strings intersect each other multiple times,
A penetrating knotless fishing net having a tortoiseshell-shaped mesh, characterized in that one two-stranded string is mutually twisted with each other two-stranded string to form a twisted part, Even when a large load is applied to the string, the penetrating part does not shift, which not only prevents misalignment, but even if one string breaks, the holding force of the penetrating part will
This will prevent it from unraveling and falling out.

〔Example〕

Next, the present invention will be explained in more detail with reference to illustrated embodiments.

First of all, in the four-through type knot shown in Figures 1 and 2, one of the two strings is twisted from a different direction (from the left in the figure), and is explained based on the transition diagram of the string in Figure 3. When the strings A and B of the book and the other two strings C and D form the penetrating part 1, a twist 2 formed by the strings A and B and a twist formed by the strings C and D are formed. 3 cross each other for the first time (third
), followed by string A,
The twist 4 formed by the strings B and the twist 5 formed by the strings C and D cross each other a second time (corresponding to the steps shown in FIGS. 13 to 18).

After this second crossing is completed, each of the two-stranded strings A and B and the other two-stranded strings C and D are twisted together with the other string to form a twisted section. (3rd
(corresponding to the steps in FIGS. 19 to 28). That is,
String A and string D are twisted together, and string B and string C are twisted together to form the twisted portion. Then,
After the twisted portions are formed, each of the two twisted strings A, B and strings C, D form twists 6 and 7, respectively, and the twists intersect with each other for the third time (see Figs. 3, 29 to 35). (corresponding to the process), the formation of the penetration part 1 is completed, and each of the two-stranded strings exiting the penetration part 1 is twisted to form a yarn foot, and each of the two-stranded strings runs diagonally. Then, the next through-hole is formed. As shown in FIG. 2, the penetrating portion 1 is tightened by the twisting of each two-strand string and becomes stable with a constant length.

Furthermore, as is clear from FIGS. 1 and 2, two adjacent strands 2, 4 and 3 formed by one two-strand string A, B and the other two-strand string C, D, respectively, After crossing the strings A and B two times in succession, strings A and B are individually twisted with other strings C and D, respectively, and then crossed with each other, so that the yarn legs are in a diagonal state. Even if the process order of crossing and twisting is added, it is possible to run the yarn legs diagonally with a predetermined number of crossings, and if necessary, the number of crossings and the weaving position of the twisting part can be adjusted. By changing these values, it becomes easy to form the penetration part 1 of a predetermined size, and all the strings passing through the penetration part 1 are brought into a state where they are hugged each other, so that the penetration part 1 itself has a fixing function. Therefore, even if one string breaks, the broken string will not come out of the penetration part 1, and the break will not become contagious, making it possible to maintain a stable net structure.

[Effect of idea]

As explained above, the knotless fishing net having a tortoiseshell-shaped mesh according to the present invention is a knotless fishing net having a tortoiseshell-shaped mesh, in which two strings each coming from different directions are crossed to form four-penetration-type penetration parts. In the knotted fishing net, each two-stranded string intersects with each other multiple times within the penetration part, and each two-stranded string on one side is twisted with each two-stranded string on the other side, respectively. Since the structure has a twisted part, by changing the number of times of crossing and twisting, it is easy and reliable to form a predetermined size of the penetration part for the size of the mesh. Even when subjected to a load such as splitting, not only does the penetrating part not shift at all, but even if one string breaks, it will not come loose or fall out due to the holding power of the penetrating part. This has the excellent effect of suppressing infections caused by broken threads.
