Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fishing reel, and more particularly to a sliding mechanism for reciprocating a spool.

[0002]

2. Description of the Related Art Regarding a fishing spinning reel, Japanese Utility Model Laid-Open Publication No. Sho 61-152269 discloses that the diameter of a spool of a spool is changed to a rear portion in order to reduce the discharge resistance of the fishing line and make it suitable for long throw. (Hereinafter referred to as "positive taper surface") is disclosed (hereinafter referred to as "prior art 1").

[0003] Further, Japanese Utility Model Registration No. 3007531 discloses a taper in which the diameter of a fishing line winding portion of a spool is gradually increased from a rear portion to a front portion in order to prevent the line from breaking when the fishing line is released. (Hereinafter, referred to as "reverse taper surface") (hereinafter, referred to as "prior art 2").

[0004]

However, if the winding line winding portion of the spool is formed on a positive taper surface as in the prior art 1, the release resistance of the fishing line can be reduced, but the resistance between the fishing lines at the time of release and the resistance of the fishing line to each other can be reduced. Due to the type, thickness, tension of the fishing line, etc., the fishing line wound around the line take-up portion of the spool collapses forward at the time of release, and a large amount of fishing line is released at a time, and it is not possible to feed smoothly, There is a possibility that the distance may be adversely affected.

[0005] Further, as in the prior art 2, if the fishing line winding portion of the spool is formed in a reverse taper surface, it is possible to prevent the line from breaking forward when the fishing line is released, but the discharge resistance of the fishing line is large. That is, there is a problem that it is inappropriate for performing long throw.

Further, regarding the manufacturing cost of the spool,
In both the prior art 1 and the prior art 2, it is necessary to perform a cutting process or a die process in order to form the fishing line winding portion of the spool on a forward tapered surface or a reverse tapered surface.
As a result, the manufacturing cost of the spool tends to increase.

An object of the present invention is to solve the above-mentioned problems of the prior art 1 and the prior art 2, that is, not only to reduce the release resistance of the fishing line but also to prevent a large amount of fishing line from being released at one time. It is another object of the present invention to provide a fishing spinning reel which enables smooth feeding and facilitates long casting, and has a low production cost.

The pin 11 has a first protrusion 11a and a second protrusion 11b, as shown in FIG. That is, the pin 11 has a first projection 11a and a second projection 11b, which project in opposite directions on both side surfaces of the pin body, respectively. These projections 11a and 11b are apparent from FIGS. As described above, the oscillator gear 10 is slightly displaced in a direction orthogonal to the axial direction of the oscillator gear 10. The first protrusion 11a of the pin 11 is engaged with a substantially elliptical cam groove G1 formed on the reel body 1. This first projection 11a

Accordingly, the same components as those of the spinning reel A according to the above-described first embodiment of the present invention are denoted by the same reference numerals, and description thereof will be omitted.

A cam groove G3 of a conventional spinning reel C
Has an elliptical shape as shown in FIG. 10, and the major axis of the ellipse intersects the moving direction of the oscillator 8, but its center substantially coincides with the center of the oscillator gear 10. ing. FIG. 12 shows the amount of movement of the oscillator 8 with respect to the rotation angle of the oscillator gear 10 in this case.
In FIG. 12, S is a straight line indicating the reference trajectory, and L4
Is a curve showing the actual trajectory of the oscillator 8. The curve in the region X3 and the curve in the region Y3 at the rotation angle of the oscillating gear 10 almost coincide with the straight line S of the reference locus, and furthermore, the slope of the approximate straight line of the curve in the region X3 and the curve in the region Y3 Are substantially the same. The oscillator 8 moves together with the spool 7, and both of them have the same moving stroke. Therefore, in the graph of FIG. 12, the horizontal axis indicating the movement amount of the oscillator 8 can be regarded as the axial length of the fishing line winding portion of the spool 7,

The curve in the region X3 and the curve in the region Y3 at the rotation angle of the oscillation gear 10 deviate from the straight line S of the reference locus. As described above, the oscillator 8 moves together with the spool 7, and both of them have the same moving stroke. Therefore, in the graph of FIG. 5, the horizontal axis indicating the movement amount of the oscillator 8 can be regarded as the axial length of the fishing line winding portion of the spool 7, and based on this fact, the range R in FIG. Of the fishing line winding section 7a of FIG. Here, as described above, the rotation speed of the rotating body 5 is controlled by the oscillation gear 10.

Accordingly, the same components as those of the spinning reel A according to the above-described first embodiment of the present invention are denoted by the same reference numerals, and description thereof will be omitted.

That is, as shown in FIG. 7, the oscillating gear 10 has a pin guide hole 10a formed of a long hole extending in the circumferential direction. On the other hand, the pin 11 has a first protrusion 11a and a second protrusion 11b which are longer than the radius of the oscillating gear 10 and are separated from each other. The first projection 11a and the second projection 11b are connected to each other via a rotating plate, and project from one end of the rotating plate in the same direction as the projecting direction of the second projection 11b and in parallel thereto. A swing pin 11c is provided. This swing pin 1
1c is inserted into the oscillation center hole 10b formed in the oscillation gear 10 on the opposite side to the above-described pin guide hole 10a with respect to the center. The first protrusion 11a is engaged with a substantially elliptical cam groove G2 formed on the reel body 1. The collar 13 is fitted to the first protrusion 11a, and the first protrusion 11a slides smoothly in the cam groove G2. On the other hand, the second protrusion 11b is inserted into the above-described pin guide port 10a formed of a long hole of the oscillating gear 10, and is further engaged with a vertical groove 8a provided in the oscillator 8 in a vertical direction. Therefore, the above-mentioned rotating plate is the first
The swing pin 11c is provided together with the protrusion 11a and the second protrusion 11b.
Can be swung around.

The spinning reel B according to the second embodiment of the present invention is easily constructed by simply changing the shape of the cam groove to the following special shape in the conventional spinning reel D shown in FIGS. 13 and 14. According to this, the winding amount of the fishing line winding portion 7a of the spool 7 can be gradually increased from the rear to the front of the spool 7 as in FIG.

Referring to FIG. 9 relating to the present invention and FIGS. 13 to 15 relating to the conventional fishing spinning reel D, while comparing the features relating to the cam groove with the conventional fishing spinning reel D having different cam groove shapes. This will be described below.

Has an elliptical shape as shown in FIG. 13, and the major axis of the ellipse intersects the moving direction of the oscillator 8, but its center substantially coincides with the center of the oscillator gear 10. ing. FIG. 15 shows the amount of movement of the oscillator 8 with respect to the rotation angle of the oscillator gear 10 in this case.
In FIG. 15, S is a straight line indicating the reference trajectory, and L5
Is a curve showing the actual trajectory of the oscillator 8. The curve in the region X4 and the curve in the region Y4 at the rotation angle of the oscillating gear 10 almost coincide with the straight line S of the reference locus, and furthermore, the slope of the approximate straight line of the curve in the region X4 and the curve in the region Y4 Are substantially the same. The oscillator 8 moves together with the spool 7, and both of them have the same moving stroke. Therefore, in the graph of FIG. 15, the horizontal axis indicating the movement amount of the oscillator 8 can be regarded as the axial length of the fishing line winding portion of the spool 7,
Based on this fact, the range R in FIG.
Of the fishing line winding section 7a of FIG. Here, since the rotating speed of the rotating body 5 is proportional to the rotating speed of the oscillating gear 10, the inclination of the approximate straight line of the curve in the region X4, that is, the rotating body 5 is attached to the rotating body 5 via the support arm and the bail arm holder. The moving speed of the rear portion of the spool 7 in the fishing line take-up portion 7a based on the position of the line roller is the inclination of the approximate straight line of the curve in the area Y4, that is, the winding speed of the spool 7 based on the position of the line roller. It is substantially the same as the moving speed of the front part in the take-out part 7a. Therefore, in the conventional spinning reel D, the winding amount of the fishing line winding portion 7a of the spool 7 is substantially uniform from the rear to the front of the spool 7.

On the other hand, the cam groove G2 of the spinning reel B according to the second embodiment of the present invention is formed in a substantially elliptical shape, and as shown in FIG. The cam groove G <b> 2 is provided so as to be deviated from the center of the oscillating gear 10 so that the upper part of the cam groove G <b> 2 is largely separated from the upper end of the oscillating gear 10 while being close to the lower end of the gear 10. FIG. 9 shows the amount of movement of the oscillator 8 with respect to the rotation angle of the oscillator gear 10 in this case.
Shown in In FIG. 9, S is a straight line indicating the reference trajectory, and L2 and L3 are a straight line and a curve indicating the actual trajectory of the oscillator 8, respectively. The straight line in the region X2 and the curve in the region Y2 at the rotation angle of the oscillation gear 10 are significantly different from the straight line S of the reference locus. As described above, the oscillator 8 moves together with the spool 7, and both of them have the same moving stroke. Therefore, in the graph of FIG. 9, the horizontal axis indicating the movement amount of the oscillator 8 can be regarded as the axial length of the fishing line winding portion of the spool 7,
Based on this fact, the range R in FIG. 9 indicates the rear part of the fishing line winding part 7a of the spool 7, and the range F indicates the front part. Here, as described above, since the rotation speed of the rotating body 5 is proportional to the rotation speed of the oscillating gear 10, the slope of the approximate straight line in the region X2 is significantly larger than the slope of the straight line S of the reference trajectory. The slope of the approximate straight line of the curve at Y2 is significantly smaller than the slope of the straight line S of the reference trajectory.
That is, the moving speed of the rear portion of the spool 7 in the fishing line winding section 7a based on the position of the line roller attached to the rotating body 5 via the support arm and the bail arm holder is based on the position of the line roller. Spool 7
Is significantly higher than the moving speed of the front portion in the fishing line winding section 7a. Therefore, since the rotation speed of the rotating body 5 is constant, the spinning reel A according to the second embodiment of the present invention is used.
In FIG. 6, the winding amount of the fishing line winding portion 7a of the spool 7 gradually increases at a large ratio from the rear to the front of the spool 7, as shown in FIG.

The sliding amount of the spool with respect to the number of rotations is different between the front part and the rear part, which not only reduces the release resistance of the fishing line, but also prevents a large amount of fishing line from being released at once, enabling smooth feeding. Thus, it is possible to provide a fishing spinning reel that can easily perform long casting and that has a low manufacturing cost.
