Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a net structure of a cage for catching fish or the like.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a basket composed of a foldable tension bone body and a net body in order to facilitate transportation and storage as a catching basket for fish and the like.
[0003]
These cages are formed by pivoting two ends of two semi-arc-shaped tension bone bodies to a circular base ring body so that the semi-arc-shaped tension bone bodies can be folded freely. A bottom mesh body serving as a bottom surface is stretched on the body, and an outer circumferential surface mesh body is stretched on the outer circumferential surface from the base ring body to the tension bone body.
[0004]
And the entrance of fish etc. is arrange | positioned in the side surface of an outer peripheral surface net body, and the cylindrical net body as a part which does not return is provided in a row.
[0005]
These basic structures are disclosed in, for example, Japanese Utility Model Publication No. 5-3013.
[0006]
[Problems to be solved by the invention]
As described above, when the outer peripheral surface mesh body is stretched on the semicircular arc brace that is pivotally attached to the circular base ring body, the mesh from the base ring body to the tension bone body must have a predetermined number of meshes. . This is because, when the tension bone body is assembled, the net body does not tension to cover the outer periphery of the bone body.
[0007]
Thus, if the outer peripheral surface mesh body is not stretched with an appropriate tension, the portion of the outer peripheral surface network body is very important because the part does not return and the entrance does not return.
[0008]
However, when the outer peripheral surface mesh body is stretched from the base ring body to the tension bone body, counting the number of meshes and positioning the tension bone body at the exact mesh position is a complicated task, The number of meshes is often incorrect, and the mesh portion located on the tension bone body is connected and fixed to the tension bone body. There is a possibility that a hole may be formed or the tension of the net body is relaxed. As a result, the function of the portion is not lowered and the capture efficiency of fish and the like may be extremely deteriorated.
[0009]
[Means for Solving the Problems]
The present invention pivotally connects both ends of a plurality of semicircular arcuate bones to a circular base annulus with a bottom mesh stretched, and between the base annulus and the tension bones and each In the cage for catching fish and the like, which is provided with an entrance for fish and the like having a portion that does not return to the side surface of the outer circumferential surface mesh body, the outer circumferential surface mesh body is stretched between the tension bone bodies and locked to the tension bone body. It is intended to provide a net structure of a catching cage for fish or the like, characterized in that the mesh thread for meshing the bone body is thicker than the mesh thread for other meshes.
[0010]
Further, the mesh portion of the outer peripheral surface mesh body that is locked to the base ring body is used as a ring locking mesh, and the mesh thread that forms the ring locking mesh is thicker than the other mesh thread. It also has a feature.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In this invention, since the mesh for meshing the bone body of the outer peripheral surface mesh body is formed of a thicker thread than the mesh thread of other meshes, the outer peripheral surface mesh body extends from the base ring body to the upper surface of the tension bone body. When tensioning, the thick thread in the mesh portion locked at the position of the tension bone body can be easily visually confirmed.
[0012]
Accordingly, the work of tensioning the outer peripheral surface mesh body can be performed accurately and easily, and different mesh portions are not erroneously locked to the tension bone body, and the function of the portion is not damaged. There is no fear.
[0013]
Further, since the mesh thread forming the mesh to be locked to the tension bone body is a thick thread, the mesh thread contacting the tension bone body is less likely to be damaged when used as a finished basket after tension.
[0014]
In particular, the mesh thread that is always in contact during the assembling and folding work of the tension bone body is usually damaged quickly, and there is a possibility that the mesh body may be damaged from this part and the function of the cage may not be performed. If the mesh yarn is a thick yarn, such a possibility of causing such damage can be prevented, and there is an effect that the function of the portion and the function as a cage can be sufficiently achieved without returning.
[0015]
In addition, by making the mesh for engaging the ring body thick, the engagement with the base annulus becomes strong, and there is no risk of breakage. The tension of the body tension can be reliably performed, and the function of the part not formed on the side surface can be sufficiently achieved.
[0016]
【Example】
An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a fish cage A for catching fish. The cage A has a circular base ring 1 and both ends of the ring 1. A skeleton is formed by a plurality of semicircular arc-shaped stretched bone bodies 2 that are pivotally connected.
[0017]
Therefore, the tension bone body 2 stands up above the base ring body 1 around the pivot portion 3 or overlaps the ring body 1 and can be folded.
[0018]
A bottom net N is stretched on the base ring body 1, and an outer peripheral surface net M is formed between the base ring body 1 and the tension bone body 2 and between the plurality of tension bone bodies 2. It is stretched.
[0019]
An intrusion port 5 for fish or the like having a non-returning portion 4 made of a cylindrical net is formed on the side surface of the outer peripheral net M.
[0020]
In the fish catching basket A formed as described above, the gist of the present invention is that the mesh yarn of the predetermined mesh portion of the outer peripheral surface mesh body M is thicker than the mesh yarn of the other mesh portion. It is in having formed in.
[0021]
That is, the mesh portion of the outer peripheral surface mesh body M that is locked to the base ring body 1 is referred to as a ring body locking mesh M-1, and the mesh portion of the outer peripheral surface mesh member M that is locked to the tensioned bone body 2 is the bone member. The stopping mesh is M-2. In addition, the mesh M-2 for locking the body is located at a predetermined number of meshes counted from the mesh M-1 for retaining the ring, and the predetermined number of meshes corresponds to the base ring 1 and the tension bone 2 Are determined in advance according to the size of the diameter, and the factors such as the tension of the outer peripheral surface mesh body M, the assembly position of the tension bone body 2 and the holding state of the portion 4 of the cylindrical mesh body are not returned. Decided in consideration.
[0022]
As shown in FIGS. 3 and 5, the bone-body-locking stitch M-2 is formed of thicker mesh yarns m-2 and mesh yarns m-3 than the mesh yarns m of other stitches.
[0023]

The mesh yarn m-2, m supported by the tension body 2 on both sides of the stitch M-2, that is, the two mesh yarns m-2 and rhombus m-3 forming the rhombic stitches are thick yarns -3 are both in contact with the bone.
[0024]
By forming the mesh yarns m-2 and m-3 with the two thick yarns in the state of FIG. 5, the support by the tension bone body 2 can be further strengthened, and the tension of the mesh body can be strengthened.
[0025]
As the thick yarn, various yarns such as twisted yarn and single yarn can be used.

【The invention's effect】
The present invention has the following effects.
[0031]
That is, according to claim 1, since the mesh thread forming the mesh for locking the bone body is a thick thread, the mesh position to be locked to the tension bone body when the outer peripheral surface mesh body is stretched on the tension bone body Is easy to understand, and the net can be installed accurately.
[0032]
Therefore, the tension of the net body is good, and the function without returning can be exhibited accurately.
[0033]
Furthermore, since the mesh thread to be locked to the tension bone body becomes a thick thread, it will not be damaged even if it is always in contact with the bone body during the assembly and folding work of the tension bone body, maintaining sufficient strength and the outer circumference. It has the effect of sufficiently maintaining the tension of the face mesh body.
[0034]
Further, according to claim 2, since the mesh thread forming the mesh for locking the annular body is also a thick thread, the strength is further increased, and the base annular body is coupled with the mesh thread for the mesh for locking the body. There is an effect that the tension of the tension net body between the tension bone body and the tension bone body is sufficiently maintained, and damage to the outer peripheral surface net body can be prevented.
