The present invention relates to a structure of a treble hook consisting of a plurality of single hooks. In addition, although a "treble hook" generally means the fishing needle which three single hooks gathered, in this specification, a "treble hook" means the fishing needle which three or more single hooks gathered.

For example, the fishing needle used for lure and the fishing needle used for sweetfish fishing have what is called a treble hook. 7 is a perspective view of a conventional general travel hook. This travel hook 1 has shown the form in which three single hooks were collected. This travel hook 1 is comprised by welding the single single hook 3 to the single double hook 2. However, the travel hook may be manufactured by welding three single hooks together. Compared to a single hook, a travel hook has an advantage that reliable hooking is realized for a fish that is targeted (see Patent Documents 1 to 3).

FIG. 8 is a cross-sectional view taken along line VIII-VIII in FIG. 7. Since the conventional travel hook 1 is manufactured as described above, the outer diameter dimension D of the shaft portion 4 of the travel hook 1 becomes larger than necessary. Therefore, the shaft portion 4 of the treble hook 1 (in particular, the shaft portion of the treble hook) is particularly referred to as an "assembly shaft portion", and the weight of the treble hook 1 also increases.

In addition, when three single hooks are gathered and a treble hook is comprised, it is preferable to arrange | position radially so that each single hook may cross | intersect with each other at an angle of 120 degrees. However, when the cross-sectional shape of each single hook is circular or spherical, the operation of radially arranging each single hook is not easy, and each single hook is difficult to be exactly radially disposed. In order to solve this problem, a jig or the like which accurately positions each single hook may be used, but in this case, there is a problem that the manufacturing cost increases.

The present invention has been made under this background. SUMMARY OF THE INVENTION The present invention provides a lightweight and inexpensive travel hook having an aggregate strength.

(1) In order to achieve the above object, the treble hook according to the present invention has a plurality of single hooks, and in the treble hook formed by the back side of the shaft portion facing each other, intersecting at a predetermined angle. One side contact plane and the other side contact plane are formed along the axial direction on the back side of each said axial part, and the one side contact plane contacts the other side contact plane formed in the axial part of the single hook adjacent to one side of the said single hook. The other side contact plane is in contact with one side contact plane formed on the shaft portion of the single hook adjacent to the other side of the single hook.

In the present invention, the treble hook is configured by abutting the shaft portions of the single hooks with each other. When the shaft portion of each single hook is abutted, the one side contact plane is in contact with the other side contact plane formed in the neighboring single hook, and the other side contact plane is in contact with the one side contact plane formed in the neighboring single hook. In addition, since the one side contact plane and the other side contact plane intersect at a predetermined angle, the shaft portions of the neighboring single hooks are reliably positioned to each other by two surfaces of the one side contact plane and the other side contact plane. In addition, the one side contact plane and the other side contact plane may be configured by a cutting surface for cutting the shaft portion in the axial direction. Therefore, the aggregate shaft portion of the travel hook constituted by abutting each shaft portion has a smaller outer diameter dimension.

The through hole may be provided along the central axis of the assembly shaft portion formed by abutting the shaft portions of the single hooks. In this structure, since the through hole is formed in the assembly shaft portion, the fishing line can penetrate through the through hole. Therefore, when the said treble hook is used, for example as a hook for sweetfish fishing, since the said treble hook is fixed to the said fishing line with the fishing line penetrating through the said through hole, the said fishing line does not damage it. There is an advantage of not receiving.

In addition, since the one side contact plane and the other side contact plane intersect at a predetermined angle, the shaft portions of the neighboring single hooks are reliably positioned to each other by two surfaces of the one side contact plane and the other side contact plane. In addition, the one side contact plane and the other side contact plane may be configured by a cutting surface for cutting the shaft portion in the axial direction. Therefore, the aggregate shaft portion of the travel hook constituted by abutting each shaft portion has a smaller outer diameter dimension.

It is preferable that the arc surface of the predetermined radius of curvature centering on the intersection point where the said one side contact plane and the said other side contact plane intersect is formed along the axial direction at the back side of the said shaft part. In this configuration, in the travel hook composed of a plurality of single hooks, a through hole is formed along the axial direction at the center of the assembly shaft portion. The fishing line may penetrate the through hole. Therefore, when the said treble hook is used, for example as a fishing hook for a sweetfish fishing, since the said treble hook is fixed to the said fishing line with the fishing line penetrating through the said through hole, the said fishing line is not damaged. This has the advantage.

In this invention, since the cross-sectional shape of the said shaft part is formed linearly, the said shaft part will be provided with a pair of contact plane which crosses each other by (360 / n) degrees. The travel hook can be configured by collecting a plurality of single hooks. The shaft portions of each single hook can be abutted with their back sides facing each other. At this time, one contact plane is in contact with the other contact plane formed in the neighboring single hook, and the other contact plane is in contact with one contact plane formed in the neighboring single hook. In addition, since one contact plane and the other contact plane intersect at the above angles, the shaft portions of neighboring single hooks are reliably positioned by the pair of contact planes. In addition, the pair of contact planes may be configured by a cutting surface for cutting the shaft portion in the axial direction. Therefore, the aggregate shaft portion of the travel hook constituted by abutting each shaft portion has a smaller outer diameter dimension.

It is preferable that the circular arc surface of predetermined radius of curvature centering on the apex of the said government is formed in the axial direction at the back side of the said shaft part. In this configuration, in the travel hook composed of a plurality of single hooks, a through hole is formed along the axial direction at the center of the assembly shaft portion. The fishing line may penetrate the through hole. Therefore, when the said treble hook is used, for example as a fishing hook for sweetfish fishing, since the said treble hook is fixed to the said fishing line with the fishing line penetrating through the said through hole, the said fishing line is not damaged. This has the advantage.

In contact with the planes 23, 19, 21. In addition, since the plane 18 and the plane 19, the plane 20 and the plane 21, and the plane 22 and the plane 23 each intersect at a predetermined angle (θ = 120 °), they are adjacent to each other. The shaft portions 14 of the single hooks 11 to 13 are reliably positioned to each other by the planes 18 to 23. Thus, since the single hooks 11 to 13 are simply and accurately arranged so as to allow a common difference (ie, equally divided by 120 °) at an angle of 120 °, the travel hook 10 is It is produced inexpensively simply.

Moreover, since the cross-sectional shape of each said shaft part 14 is formed linearly as mentioned above, the outer diameter dimension of the assembly shaft part 24 of the travel hook comprised by each shaft part 14 butt | matching becomes small. . Therefore, the designer of the travel hook 10 can set the outer diameter dimension of the assembly shaft portion 24 to an appropriate value in order to secure the appropriate strength of the assembly shaft portion 24. Thereby, there exists an advantage that the weight of the said travel hook 10 can also be aimed at.

Second Embodiment

Next, a second embodiment of the present invention will be described.

This travel hook 30 is comprised from three single hooks 31-33. FIG. 6: is a perspective view of the single hook 31 which comprises this treble hook 30. As shown in FIG. The single hooks 31 to 33 have shown the same form.

The difference between the treble hook 30 according to the present embodiment and the treble hook 10 according to the first embodiment is that the shaft portions 14 of the respective single hooks 31 to 33 are opposed to each other. The through hole 34 is provided along the central axis of the assembly shaft portion 24. In addition, about another structure, it is the same as that of the said treble hook 10.

As shown in FIG. 6, the single hook 31 has a groove 35. This groove 35 is provided along the axial direction on the back side of the shaft portion 14. Specifically, an arcuate surface 36 centered on the intersection point where the plane 18 and the plane 19 intersect, that is, the government part 17 (see FIG. 3), is formed along the shaft portion 14. The radius of curvature of the circular arc surface 36 is d / 2. In the present embodiment, the groove 35 is provided only in the shaft portion 14, as shown in FIG. 6, but may be continued to the recessed portion 15 and the needle tip portion 16.

Similarly to the first embodiment, each single hook 31 to 33 constitutes a travel hook 30 by abutting the back side of each shaft portion 14, and each of the single hooks 31 to 33 respectively. The assembly shaft portion 24 of the treble hook 30 is configured in a state in which the shaft portions 14 are collected. Each of the single hooks 31 to 33 is fixed to each other by welding the shaft portions 14 to each other, but may be fixed to each other by an adhesive or a thread.

In the travel hook 30 according to the present embodiment, the assembly shaft portion 24 has a moderate strength, light weight, and low cost, similar to the travel hook 10 according to the first embodiment. In addition, since the groove 35 is provided in each of the single hooks 31 to 33, the through hole 34 is formed in the assembly shaft portion 24. The fishing line may penetrate the through hole 34. Therefore, when the treble hook 30 is used, for example, as a hook for sweetfish fishing, the treble hook 30 is fixed to the fishing line with the fishing line penetrating the through hole 34. This has the advantage that the fishing line is not damaged.

Although the treble hooks 10 and 30 which concern on each said embodiment consist of three single hooks 11-13, 31-33, respectively, the number of the single hooks which comprise the treble hooks 10 and 30 especially It is not limited.
