DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a net for catching fish.

[0002]

2. Description of the Related Art Hitherto, a staple net 11 has a bag-like shape in which a side portion is formed in a cylindrical shape having the same diameter as the frame 13 and a lower end thereof is closed by a bottom portion. Is taken in and suspended. In use, the opening O formed by the frame 13 is used.
The fish is taken into the catching net 14 from the fish.

[0003] The side portion of the intake net 14 is formed by knitting mesh stages having the same number of meshes as the mesh stages forming the open ends thereof in multiple stages. Then, the capture network 14 of the tie network 11
At the beginning of use, has a substantially cylindrical shape as shown by a two-dot chain line S in FIG.

[0004]

However, in the mesh net 11 configured as described above, the load is applied to the intake net 14 by repeated use, and as a result, as shown in FIG. The portion is deformed so as to be narrowed toward the center of the intake net 14 with a portion below the vicinity of the opening O as a center. And the diameter of this deformed portion was smaller than the diameter of the frame 13.

[0005] When such a net 11 is used for catching fish, a deformed portion of the catching net 14 projecting inward becomes an obstacle, and the fish cannot be taken in smoothly. Further, even if the fish is once taken into the intake net 14, there is a problem that the fish goes up along the overhanging deformed portion and escapes from the opening O again.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a net which does not become smaller than the diameter of the frame even if it is repeatedly used. It is in.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 is arranged such that the number of meshes in the vicinity of the opening of the intake net is larger than the number of meshes in the upper mesh. The gist is that the knitting is performed by increasing the number of meshes in the lower mesh.

According to a second aspect of the present invention, the number of meshes in the vicinity of the opening of the intake net is increased by increasing the number of meshes in the lower mesh than the number of meshes in the upper mesh. At the same time, each mesh step constituting the body of the intake net was knitted with the same number of meshes.

According to the third aspect of the present invention, the number of meshes of the second mesh stage, which is the lower stage of the first mesh stage forming the open end of the intake net, is larger than that of the first mesh stage. The number of meshes of the third mesh lower than the second mesh is larger than the number of meshes of the second mesh, and each mesh forming the trunk of the intake net is connected to the third mesh. Knitted with the number of meshes in the column.

[0010]

According to the first aspect of the present invention, the diameter of the lower mesh step is larger than the diameter of the upper mesh step in the mesh step forming the vicinity of the opening of the intake net.

According to the second aspect of the present invention, the diameter of the lower mesh step is larger than the diameter of the upper mesh step in the mesh step forming the vicinity of the opening of the intake net. Further, the body of the intake net is formed in a cylindrical shape at the lower end of the mesh step forming the vicinity of the opening.

According to the third aspect of the present invention, the diameter of the second mesh step below the first mesh step forming the open end of the intake net is larger than that of the first mesh step. Then, the diameter of the lower third mesh stage is larger than the diameter of the second mesh stage. Further, the body of the intake net is formed in a cylindrical shape at the lower end of the third mesh step.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
This will be described with reference to FIG. As shown in FIG. 1, a rod-shaped handle 3 is attached to a ring-shaped frame 2 forming an opening O of a net 1. At the lower end of the entire periphery of the frame 2, a bag-shaped intake net 4 is suspended.

The intake net 4 is formed by knitting a large number of diamond-shaped nets with nylon monofilaments. The intake net 4 has a cylindrical body 4a having a diameter larger than that of the frame 2, a bottom 4b closing the lower end thereof, and an upper end of the body 4a. And a narrowed portion 4c having a smaller diameter.

In order to knit the intake net 4, first, a substantially dish-shaped bottom portion 4b is formed by knitting mesh stages in which meshes are arranged in a ring in the same center. That is, by increasing the number of meshes as the number of meshes increases toward the outer mesh, an annular mesh with a larger diameter is formed. When the number of meshes in the mesh step becomes 500, the cylindrical body 4a is formed above the bottom 4b by knitting with the mesh number of the next and subsequent mesh steps remaining 500. The diameter of the body 4 a is larger than the diameter of the frame 2.

After knitting the body 4a, the squeezed portion 4c composed of three mesh steps is knitted as follows. First, the number of meshes of the mesh stage L3 (the third stage) immediately before the mesh stage L1 (hereinafter referred to as the first stage) forming the opening end is knitted at 500. Thereafter, when knitting the next mesh stage L2 (the second mesh stage), the meshes of the third stage L3 are adjacent to each other by a predetermined number (every 25 in this embodiment) as shown in FIG. The mesh of the second stage L2 is made in the same manner as the mesh. In this way, knitting is performed such that the number of meshes in the second stage L2 is reduced by 20 from the number of meshes in the third stage L3 to 480. That is, as shown in FIG. 3, the method of reducing the number of meshes is to connect the upper ends of the adjacent meshes M1 and M2 forming the third stage L3 to the lower end of the mesh M3 of the second stage L2 together to reduce the number of meshes to one. Reduce the number.

Next, the number of meshes is set to 4 in the same manner as in the first stage L1.
The knitting net 4 is formed by knitting to 60 pieces. The number of meshes of the first stage L1 forming the open end is determined by the size of the mesh and the frame 2
It is set according to the diameter of. For example, in the present embodiment, the mesh size is nominally 2.5 mm and the diameter of the frame 2 is 36 cm, whereas the first stage L forming an open end is used.
The number of meshes of 1 is 460. When the diameter of the frame 2 is 39 cm, the number of meshes of the first stage L1 is 510.
When the mesh size is 1.5 mm, the number of meshes of the first stage L1 is 710 when the diameter of the frame 2 is 36 cm.

The capture network 4 formed as described above is shown in FIGS.
As shown in FIG. 2, the net 1 is formed by passing the thread 5 of the monofilament through the first stage L1 and tying the thread 5 to the frame 2 with the tying thread 6 at a plurality of places.

When the net 1 constructed as described above is used for catching fish, the diameter of the intake net 4 gradually becomes larger than the diameter of the frame 2 as the squeezing portion 4c moves downward at the beginning of use. At the same time, the body 4a has a cylindrical shape having the same diameter as the diameter of the lower end of the throttle 4c. Therefore, the fish is taken in smoothly without the inside of the taking-in net 4 becoming an obstacle.

Further, when used repeatedly, the acquisition network 4
Is deformed so that the upper part of the trunk 4a is narrowed toward the center of the intake net 4. However, at the beginning of use, the intake net 4 is
As c becomes lower, it gradually becomes larger than the frame 2 and the diameter of the body 4a is formed in a cylindrical shape having the same diameter as the diameter of the lower end of the throttle 4c. Therefore, even if it is repeatedly used, the diameter of the deformed portion does not become smaller than the diameter of the frame 2. As a result, the fish net 1 of the present embodiment allows the fish to be smoothly taken into the bottom portion 4b without causing an obstacle when the fish is taken inside the net 4 even when used repeatedly. Further, the fish once taken into the bottom 4b does not escape to the outside along the inside of the overhanging catching net 4.

It should be noted that the present invention is not limited to the above embodiment, but may be configured as follows without departing from the spirit of the invention. (1) In the above-described embodiment, a cylindrical shape is formed by keeping the number of meshes of each mesh step for knitting the body 4a, but this may be changed to a shape other than the cylindrical shape by changing the number of meshes. Good.

(2) In the above embodiment, the squeezed portion 4c of the intake net 4 is formed by three mesh stages, and the number of meshes of the second stage L2 is changed to 460 meshes of the first stage L1. The number was increased by 20 and the number of meshes in the third stage L3 was increased by 20 more than the number of meshes in the second stage L2. The number of mesh stages forming the narrowed portion 4c and the number of meshes to be increased between the mesh stages are:
Of course, the aperture 4c may be appropriately set within the range where the aperture 4c is formed in the vicinity of the opening according to the diameter of the frame 2, the size of the mesh, and the like.

(3) In (2), the number of meshes may be increased every other stage as long as the object is achieved, or may be increased every two stages or more. (4) In the above embodiment, the bottom portion 4b is formed in a substantially dish shape, but may be formed in another shape.

(5) In the above embodiment, the material of the intake net 4 is made of nylon monofilament, but may be made of other synthetic fiber or natural fiber.
