Description

[Detailed Description of the Invention] (Object of the Invention) This invention is directed to a hollow rod among various types of fishing rods.
In other words, it relates to an improved structure of a fishing rod in which the line passes through the internal space of a hollow rod that can be disassembled into several pieces, and in particular, it smoothes the movement of the line and prevents damage to the line due to movement. It is an object of the present invention to provide a hollow rod having a structure that is advantageous for prevention.

(Prior Art) As people have more leisure time, it has become possible for people to enjoy more variety of leisure activities than ever before. Fishing is also one of the popular leisure activities, and for these people, various improvements have been made to fishing equipment, and many convenient tools have become available. fishing rod
Anglers use several types of fishing rods depending on the type of fish they catch, the fishing method, or their personal preferences, so fishing tackle stores carry many types to meet their expectations. Fishing rods are provided.

Among these various fishing rods, there is a hollow rod that is extremely popular among fishing enthusiasts. This fishing rod is a parallel rod with a structure that allows the hollow rod to be disassembled into multiple rods, and is also structured to allow the guide line to pass through using the internal space of the hollow rod, so that the so-called guide ring can be placed outside the rod. Unlike the most common fixed fishing rods, the line has the advantage of not becoming too loose or getting caught on other objects when being wound up or unwinded. However, on the other hand, in the case of this hollow rod, when the thread moves back and forth in the hollow rod many times, it comes into contact with the step in the hollow part of each disassembly rod and is subjected to frictional resistance. It has the disadvantage that the threads are damaged or worn out during use, and perhaps due to this, it is not popular among people other than enthusiasts, and as a result, this disadvantage This is expected to be one of the factors that prevents the use of hollow rods.

This invention was finally completed after 11 years of development and research focusing on the current situation as described above, and has the structure as described in detail below.

(Structure of the Invention) As clearly understood from the representative embodiments of the present invention shown in the drawings, the present invention provides a guide ring 2 which is rounded at least on the inner peripheral opening 21 side in its cross section. , so that the inner circumferential opening 21 thereof is slightly protruded from the inner circumferential surface of the hollow portion near the tip of the joint flat portion 11 of each disassembly rod 1', 1', . . . forming the hollow rod body 1. The gist of the structure is a fixed hollow rod.

In order to reduce frictional resistance when the guide thread R passes through the inner circumferential opening 21 of the guide ring 2, at least the inner circumferential opening 21 side of the guide ring 2 is restricted to have a rounded cross-sectional shape such as a circle or an ellipse. The material must be made of a wear-resistant material that will not wear out due to frictional resistance with the road thread R, such as ceramic materials, stainless steel, amorphous metal materials, etc. This guide ring 2 can be adopted as follows.
Joint flat part 11 of the disassembly rod on the insertion side of each disassembly rod
It is fixed in the hollow part near the tip.

The inner peripheral opening of the guide ring 2 is the disassembly rod 1'1',...-
In addition to the configurations shown in the following embodiments, the means for arranging the joint half 11 in the vicinity of the tip so as to project slightly from the inner circumferential surface of the hollow part include, for example, a guide, although not particularly shown in the drawings. The outer periphery of the ring 2 itself is formed into a medium-wide one (a rice ball-shaped cross-section with a vertical cross-section butt end shape and an apex at the inner peripheral end side), and the wide-middle portion is directly disassembled by the rods 11', . . .
. . . It can be glued and fixed to the inner circumferential surface of the hollow part near the tip of the joint half 11 with adhesive, or the wide part can be further expanded into a brim shape to make it easier to glue. The fixing cylinder 3 shown in FIG. 1 may be integrally formed with the material of the guide ring 2) and may be bonded and fixed.

Note that the fixing position 1 of the guide ring 2 to the fixed cylinder 3 is not particularly defined, but the disassembly rods 1', 1', .
The fixing position should be determined so that it does not go too far from the tip of the joint flat part 11.

Hereinafter, the configuration of each illustrated embodiment will be specifically explained in detail.

(Embodiment 1) The main part horizontal cross-sectional perspective view of the hollow rod body 1 in an exploded state shown in FIG. 1 and the main part vertical cross-sectional view shown in FIG. This is a typical example with features in the fixing means.

That is, a pair of divided fixed cylinders 3a in which the fixed cylinder 3 is thinner than the cross-sectional diameter dimension from the outer periphery to the inner peripheral opening of the guide ring 2.
, 3b, and the pair of divided fixed cylinders 3a, 3b are arranged one after another on the inner peripheral surface of the hollow part near the tip of the joint flat part 11 of each disassembly rod 1', 1'... By arranging and fixing the guide ring 2 as shown in FIG.

The pair of split fixed cylinders 3a and 3b are made of elastic material such as rubber material, silicone material, etc.
It may be formed of a cylindrical body made of plastic, metal, or the like and having an outer shape that tightly fits into the inner circumferential surface of the hollow portion near the tip.

These divided fixed cylinder bodies 3a and 3b were first applied adhesive to the outer peripheral surface of one of the divided fixed cylinder bodies 3a, and inserted into the hollow inner peripheral surface near the tip of the joint flat part 11 of the disassembly rod 1'. Insert the upper guide ring 2 and attach the divided fixed cylinder 3a
The guide ring 2 is aligned so that it follows the front end of the guide ring 2, and finally the other divided fixed cylinder 3b is inserted by applying adhesive on its outer circumferential surface in the same way. The front and rear of these pairs of divided fixed cylinders 3a,
3b to realize a fixed structure.

(Embodiment B 2) The horizontal sectional perspective view of the main part in FIG. 3 and the vertical sectional view of the moving main part in FIG. 4 are examples of other fixing means for the guide ring 2.

In this example, the guide ring 2 is fixed to the thin fixed cylinder 3' by welding the entire outer peripheral surface or key points of the guide ring 2 to the inner circumferential wall of the thin fixed cylinder 3'. This is what I did.

In this example, since the guide ring 2 is welded to the fixed cylinder 3', both materials are made of metal that can be welded, but this is equivalent to welding. If there is sufficient strength, it is also possible to use an adhesive for integration. Unlike the case of welding, when this method is used, it is possible to combine the guide ring 2 and the fixed cylinder 3' made of various materials as described above.

The guide ring 2 integrated in this way is attached to the fixed cylinder 3'.
Apply adhesive to the outer circumferential surface of each disassembly rod 1', 1'
By inserting and adhering into the inner circumferential surface of the hollow part near the tip of the joint flat part 11, a structure fixed in a predetermined manner is realized.

In the figure, reference numeral 4 indicates a welding location between the guide ring 2 and the thin-walled fixed cylinder 3'.

(Operation and Effect) The hollow rod of the present invention having the above-mentioned configuration has a smooth guide ring 2 further inside the acute-angled step at the tip of the connecting rod portion 11 of each disassembled rod of the hollow rod body 1. Since the inner circumferential opening of the hollow rod body 1 is fixed in a slightly protruding manner, the guide thread R is
When the decomposition rods 11', . . .
It touches the smooth inner peripheral opening of the guide ring 2 and moves back and forth without touching the sharp step at the tip of the connecting rod part 11. Each disassembled rod 1', 1', .
The structure of the present invention exhibits the excellent effect of reliably preventing damage or wear caused by contact with the step at the tip of the joint flat portion 11.

Moreover, the fixation of the guide ring 2 to the disassembled rod 1', 1', etc. to the tip of the connecting rod part 11, which can exhibit the above-mentioned effects, cannot be achieved with only the guide ring 2 itself. The fixing cylinder 3
This is realized by a combination structure with
As a result, the guide ring 2 can be securely and easily fixed.

In particular, when the fixing structure of the guide ring 2 is realized by a structure in which the front and rear parts are sandwiched between the split fixing cylinders 3a and 3b, as shown in Embodiment 1, the fixing strength is ensured. It can be made into the most ideal structure, and as shown in Example 2,
In the case of explosive attachment to the inside of the fixed cylinder 3, since a large number of guide rings can be manufactured in advance as two parts, the joint flats 1 of the disassembly rods 1', 1...
The manufacturing feature can be such that attachment to one tip can be carried out efficiently.

As mentioned above, the threading rod of the present invention has the excellent effect of smoothing the thread movement within the hollow rod body and preventing damage or abrasion of the thread, and is also easy and inexpensive to manufacture. It is expected that this product will be of great help in popularizing the rod as a more popular fishing rod.
