Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing rod stopper.

[0002]

2. Description of the Related Art In a joint rod, when a small-diameter rod pipe is housed in a large-diameter rod pipe, it is common to plug the pipe from the outside. 4-43
It is disclosed in Japanese Patent No. 966. By sliding or rotating the operating body, the pressing piece is moved in the radial direction to expand the outer diameter of the plug body made of an elastic material, fixing the plug body to the rod tube, and conversely reducing the outer diameter. To facilitate removal of the plug.

[0003]

However, when the operating body is rotated and used, the support state of the pressing piece by the supporting body is defined, and the pressing piece relatively rotates the operating body in the circumferential direction. In this case, since there is no positive play in the groove of the operating body except in the direction of rotation thereof, when the pressing piece rides on the highest outer peripheral surface of the operating body and then falls into the holding portion. However, there was no sense of moderation, and I was worried about the operation because I could not distinguish it from the tight condition on the outer peripheral surface before that.

Therefore, according to the present invention, when the knob portion is rotated to increase or decrease the outer diameter of the stopper to fix or remove the stopper from the rod tube, the operation of the knob portion is felt. The purpose is to provide a stopper that is present.

[0005]

In view of the above object, the present invention provides a stopper having a recess formed in the longitudinal direction and the wall of the recess having elasticity in the radial direction, and the plug inserted into the recess of the stopper. Is
An operating shaft body having a knob portion, a pressing body disposed between the outer periphery of the operating shaft body and the wall surface of the recess of the plug body, and a restriction hole for restricting the movement position of the pressing body in the recessed part. And a first hollow portion formed on the outer periphery of the operating shaft body and capable of loosely receiving the pressing body, and a first hollow portion formed at a position circumferentially separated from the hollow portion. And a second recess formed so as to push up the pressing body more than the recess and having a width larger than the width of the restriction hole in the longitudinal direction, the plug for a fishing rod is provided. .

[0006]

[Operation] The first of the operation shaft body is held in the restriction hole of the holding cylinder.
The wall of the recess of the stopper does not project when the pressing body is received in the depression of the operating body, but when the operating shaft is rotated, the pressing body comes out of the first depression and the outer peripheral surface of the operating shaft is rotated. Climbing up, the turning operation feels tight, and eventually, the person sits down in the second recess that is circumferentially separated from the first recess. in this case,
The pressing body moves in the circumferential direction relative to the outer circumference of the operating shaft body at a substantially fixed position in the longitudinal direction by the restriction hole of the holding cylinder body, but the second recess of the operating shaft body is longer than the longitudinal direction of the restricting hole of the holding cylinder body. Since it has a width larger than the directional width, the operating shaft is rotated, and the pressing body relatively crawls out of the first hollow portion and climbs to the outer peripheral surface of the operating shaft body. The inner surface of the rod tube can be pressed by falling into the second recess formed so as to push up the pressing body and projecting the wall of the plug body to the outside, but this is the rotation direction when seated in this second recess. Since there is a degree of play in the longitudinal direction that is different from the circumferential direction, it is possible to obtain a moderation sensation that suddenly becomes loose from the sensation of a rotating operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail based on the embodiments shown in the accompanying drawings. 1 is a vertical cross-sectional view of a fishing rod plug according to the present invention, FIG. 2 is a vertical cross-sectional view showing a state in which the plug is activated, FIG. 3 is a cross-sectional view taken along the line C-C of FIG. FIG. 2 is an enlarged view of a main part of FIG. The stopper 12 made of an elastic member such as rubber is formed in the center in the longitudinal direction and has a recess 12H having a circular cross section.

A metal holding cylinder 14 is provided in the recess 12H.
Is inserted, and the operation shaft 18 having a circular cross section is rotatably inserted therein. Further, a knob 18A for operation is formed on the head of the operation shaft 18. Further, an outer frame portion 14A is formed on the head of the holding cylinder body 14, and the plug is inserted in the arrow direction so that the rod tube 10 is inserted between the outer frame portion 14A and the outer circumference of the plug body 12. Push in.

The holding cylinder 14 is fixed by adhering it to the wall surface of the recess of the plug 12. A groove 18B is provided in an end portion of the operating shaft body 18, and a retaining ring 20 having a spring property is locked therein, and the retaining ring 20 is brought into contact with the end surface of the holding cylinder body 14 for operation. The shaft 18 is prevented from coming off.

Two holding holes 14H having a predetermined size are formed in the holding cylinder 14 at a distance of 180 degrees in the circumferential direction.
On the other hand, two first hollow portions 18C are formed on the outer periphery of the operation shaft body 18 corresponding to the restriction holes 14H.
A second recess 18D is formed between these first recesses 18C. A metal spherical body 16 serving as a pressing body is disposed in the restriction hole 14H, and the normal spherical body 16 housed in the first hollow portion 18C hardly expands the wall of the concave portion of the plug body 12. Therefore, in this state, it is easy to insert or pull out the rod tube 10.

From the normal state of FIG.
When the sphere 16 is rotated about 0 degree, the sphere 16 is seated in the second recess 18D, and the wall of the plug 12 partially expands outward as shown in FIG. Therefore, if the plug is inserted into the rod tube 10, the protrusion causes a tight engagement relationship, and the plug is attached to the rod tube 1.
It is possible to prevent slipping out of 0. When loosening the knob portion 18A by rotating it 90 degrees, the spherical body 16 falls into the first hollow portion 18C and the state shown in FIG.
No wall protrusion. Therefore, it can be easily removed.

As shown in FIG. 4, the diameter LH of the restriction hole 14H of the holding cylinder 14 is slightly larger than the diameter of the sphere 16, and the sphere 16 can freely rotate within the restriction hole 14H, but it is almost the same. The position is regulated.
On the other hand, the first hollow portion 18C formed in the operation shaft body 18 is formed so as to have a depth such that when the spherical body 16 is accommodated, the spherical body 16 hardly presses the wall surface of the recess 12H of the plug body 12. ing. As shown in FIG. 3, the deepest position is the central portion in the circumferential direction of the first hollow portion 18C, and both sides thereof are formed so that the depth gradually decreases. The width LC in the longitudinal direction is set to be larger than the diameter LH so that the sphere 16 can be smoothly rotated when the operation shaft 18 is rotated.

The width and depth of the second recess 18D in the circumferential direction are such that when the sphere 16 is received and seated, the amount L of depression of the sphere 16 is 2 to 20% of the diameter of the sphere. It is formed to a certain extent. For example, an example is a sphere having a diameter of 4 mm and the amount L of depression is about 0.2 mm. Further, the longitudinal dimension LD is formed larger than the diameter (also the longitudinal dimension) LH of the restriction hole 14H of the holding cylindrical body 14, and the operating shaft body 18 moves slightly in the longitudinal direction due to the engagement gap. However, the movement of the sphere 16 is not restricted in the longitudinal direction.

Therefore, when the operating shaft 18 is rotated counterclockwise in FIG. 3 from the state of FIG. 1, the outer peripheral surface 18S of the operating shaft 18 is moved from the position where the spherical body 16 is indicated by the chain double-dashed line 16A.
Get on. In the middle of this process, the spherical body 16 gradually and strongly presses the wall surface of the recess 12H of the plug 12 to form the outer peripheral surface 18S.
The pressing force is the largest at the position indicated by the alternate long and short dash line 16B on the vehicle. Then, as shown by the solid line, the spherical body 16 is seated in the second recess 18D and the pressing force thereof is reduced.

At the time of this seating, the spherical body 16 moves into the operating shaft body 18.
The longitudinal direction of the second recess 18D is restricted by the restriction hole 14H for holding the spherical body 16 so that it is not restricted to directions other than the circumferential direction.
Has a width LD larger than the width LH of the plug body 12 and therefore has a degree of play, so that when the spherical body 16 is seated by dropping from the outer peripheral surface 18S of the operating shaft body 18 by the amount L described above, It is possible to create a feeling of moderation in which the pressing force on the wall surface of the concave portion of the plug changes suddenly, and a sense of security is created in the operation of fixing the plug to the rod tube 10. It should be noted that if a registration mark is formed on the outer peripheral surface of the knob portion 18A of the operation shaft body 18 and the surface of the outer frame portion 14A of the holding cylinder body 14 so as to be matched in the seated state, a further sense of security is provided.

Although the spherical body 16 is used as the pressing body in the above description, it may be a cylindrical or cylindrical roller member, and in this case, the restriction hole 14H of the holding cylinder body 14 may be a rectangular restriction hole, the longitudinal direction thereof. The width LD in the longitudinal direction of the second recess 18D is formed to be larger than the width LH. In this way, as in the case of the sphere, it is possible to obtain a feeling of moderation when sitting.
Further, the pressing body, the holding cylinder body 14, and the operating shaft body 18 are not limited to metal, and may be formed of a resin material or the like.

[0017]

As is apparent from the above description, according to the present invention, the position of the pressing body is restricted by the restriction hole of the holding cylinder.
The width of the recess (second recess) at the position where the plug is fixed to the rod tube is longer than the width of the restriction hole of the holder in that direction. Therefore, a sudden change in the force pressing the plug body when seated can be grasped as a moderation feeling, and it can be understood that the rod tube can be fixed to the rod tube, which gives a sense of security in the operation. Further, when the plug is inserted into or removed from the rod tube, if the pressing body is housed in the first recess, it can be performed by an extremely light operation.
