Description

[Detailed description of the invention] This invention relates to the improvement of a structural part such as a barrel-shaped ring that is attached between the fishing tackle line and hook element.

Conventionally, this type of structure has a single cylindrical body 11 as shown in FIG.
The rotating parts 13 of the attachment part 12 for connecting the thread and the hook are fitted into the openings at both ends of the cylinder body 11, respectively, and the openings at both ends of the cylindrical body 11 are connected by drawing with a drawing die.

However, when narrowing both end openings of the cylinder 11 (
Depending on the length error of the cylinder 11, the hardness of the material of the cylinder 11, the degree of abrasion of the drawing die, etc., the diameter W of the openings at both ends of the cylinder 11 may not be constant (and a standardized product cannot be produced). Therefore, for example, when the aperture W of both end openings of the cylindrical body 11 is narrowed down to a diameter slightly larger than a predetermined aperture, there is a drawback that the rotating parts 13 of each attachment part 12 can completely slip out.

In addition, since the inner surface of the cylinder 11 is not polished and has a rough surface, the rotating parts 1 of each mounting part 12
3 gets caught and does not rotate smoothly, and when both end openings of the cylinder 11 are narrowed, both end openings become slanted (tapered). Combined with the possibility that the rotating gear 13 may become stuck on both ends of the cylindrical body 11 and become unrotatable, there are drawbacks such as the fact that the return effect of the threads, hooks, etc. cannot be sufficiently exerted. Ta.

Therefore, this idea was devised to eliminate the above-mentioned drawbacks, and consists of a polished metal plate with openings of the same diameter protruding from one end. Different outer barrel materials and inner barrel materials are squeezed out and punched out, and one tip of each mouth of the outer and inner barrel materials is provided with a rolled-up piece that is curled to the outside, and the other end of the outer and inner barrel materials is cut out. An outer barrel body and an inner barrel body are formed in such a way that an inwardly bent piece is provided in the outer barrel body, and the inner barrel body is arranged inside the outer barrel body, and the openings of these bodies are arranged at opposite ends. f
This ensures that the diameters of the openings at both ends of the outer tank body and inner barrel body are always constant, and that the rotating parts of each attachment part are prevented from slipping out completely (as well as rubbing the rotating parts of each attachment part). To provide a structural part such as a barrel-shaped monkey ring, etc., which eliminates hooks and jams, smoothes the rotation, and fully exhibits the effect of twisting threads, hooks, etc.

An embodiment of this invention will be described below with reference to the drawings.

The structure of this invention is composed of an outer barrel body A and an inner barrel body B, as shown in FIGS. 1 to 3.

The outer barrel body A and the inner barrel body B are made of polished metal plates, each having a mouth portion 1 having the same predetermined diameter H and having a slightly different diameter. A cylindrical outer tank material 2 and an inner barrel material 3 are each gradually squeezed out by sequential press processing.

Furthermore, the outer tank material 2 and the inner tank material 3 have a winding piece 4 which is curled outwardly by press working at the tip of each opening 1, and the other end of the inner tank material 3 (this is the inner part). Orientation bending piece 5
Each is formed so as to be slightly caulked.

Then, after fitting the inner tank B into the inside of the outer tank body A so that these mouth parts 1 are arranged at opposite ends,
At the other end of the outer tank body A, an inwardly bent piece 6 similar to the bent piece 5 of the inner tank body B is slightly crimped.

As shown in FIG. 1 by the dashed line, each attachment part 12 for the guide line and hook tie is attached to one end of the rotating part 13 before fitting the inner tank body B into the inside of the outer tank body A. Two straight metal wires 14 of appropriate length are bent into bent pieces 6 and 5, respectively, so that the rotating parts 13 are located inside the mouth 1 side of the outer tank body A and the inner tank body B.
Insert it from the side, and then insert the inner tank B inside the outer tank A.
After fitting, the other end of each gold wire 14 is shaped so that a ring part 15 for tying the wire and hook is wound around it.

Therefore, in this invention, the outer tank body A and the inner tank body B are squeezed out from a polished metal plate so that the mouth part (2) having the same predetermined diameter H projects from one end. Therefore, regardless of the length error of the outer tank body A and the inner tank body B, the hardness of the material, the degree of wear of the drawing die, etc., the outer tank body A and the inner tank body B are Diameter H of both end openings 1
Since a standardized product is produced by constantly performing a constant f, it is possible to reliably prevent the rotating parts 13 from slipping out of each mounting part 12.

In addition, since the outer tank body A and the inner tank body B are formed from polished metal plates, the inner surfaces of the outer tank body A and the inner tank body B are smooth (rounded), so that each mounting portion 12 The rotating parts 13 rotate extremely smoothly (L-) without getting caught, and the inner surface of each mouth part 1 side of the outer tank body A and inner tank body B and each mounting part 12 Rotating class 13
(As a result, the outer tank body A and the inner tank body B and the rotating parts 13 of each mounting part 12 come into surface contact with each other, so that the rotating parts 13 of each mounting part 12 are tilted ( Together with the ability to prevent the rotary member 13 from becoming unrotatable due to jamming of the both end openings 1, the twisting effect of the thread, hook element, etc. can be fully exerted.

Moreover, since the winding piece 4 is provided by curling the tip of each mouth part 1 of the outer tank body A and the inner tank body B to the outside, %(
Not only can sufficient strength be obtained at both end openings 1 to which tensile force is applied by the rotating parts 131 of each attachment part 12, but also because it has a double structure consisting of an outer tank body A and an inner tank body B, Sufficient strength is obtained overall, and the outer tank body A and the inner tank body B can be formed with a metal plate less than half the thickness of the conventional cylinder body 11 (this is expected to have the effect of having sufficient strength). can.

As explained above, according to this invention, it is possible to reliably prevent the rotating parts of each attachment part from slipping out, and it is also possible to fully exert the effect of returning the threads and hooks, etc., and also to have sufficient strength. Various excellent effects can be obtained, such as:
