Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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 Conventionally, as a sliding mechanism of a fishing reel, a mechanism described in Japanese Patent Publication No. 2-60295 is known. FIG. 16 is a diagram showing an outline of this sliding mechanism. This is a handle shaft (not shown) extending in the left-right direction of the reel body, and an oscillating gear 101 that is interlocked with the rotation of the handle shaft supported by a shaft parallel to the handle shaft.
An oscillator 103 in contact with an oscillating gear 101 fixed to a spool shaft 102 extending in the front-rear direction of the reel body.
A longitudinal groove 103a provided on the reel body, a long hole 101a provided in the radial direction of the oscillating gear 101, and an elliptical cam groove 104 provided in the reel body in the front-rear direction so as to surround the oscillating gear shaft. And a pin 105 that penetrates the elongated hole 101a and has one end inserted into the cam groove 104 and the other end inserted into the vertical groove 103a.

However, when the handle shaft is rotated, the oscillating gear 101 is rotated, and the long hole 101a thereof is formed.
The inserted pin 105 follows the elliptical cam groove 104 into which one end is inserted, and guide-moves by the long hole 101a provided in the radial direction of the oscillating gear 101, while performing an elliptical turning motion. Since the other end of the pin 105 is inserted into the vertical groove 103a, the oscillator 103 follows the elliptical turning motion of the pin 105 and reciprocates back and forth. Therefore, the spool shaft 102 and the spool (not shown) attached to the tip of the spool shaft 102 also reciprocate forward and backward in front of the reel unit.

[0004]

However, in the sliding mechanism of the fishing reel as described above, since the pin is only inserted into the long hole and the cam groove of the oscillating gear, the pin is inserted. Tends to tilt, the smoothness of the movement of the transmission system from the oscillating gear to the oscillator is impaired, and the spool also rattles in the front-back direction, which hinders the winding of the fishing line. In addition, when a shock load is applied to the spool due to a fall of the reel or the like, a large force is applied to the pin via the spool shaft, so that the pin is easily twisted or damaged. Further, the direction of the cam groove must be matched with the direction of the spool shaft, which restricts the shape of the reel body and the arrangement of parts.
Furthermore, since the pin has to be provided inside the root circle of the oscillating gear, the stroke of the oscillator or spool cannot be made larger than the diameter of the oscillating gear. Furthermore, when the pin is guided by a long hole provided in the radial direction of the oscillating gear that rotates at a constant angular velocity while being restrained by an elliptical cam groove that is flat in the vertical direction and long in the front and rear direction on the main body, In the vertical position, the sliding direction of the oscillator coincides with the sliding direction of the oscillator, and in the front-back position, the sliding direction of the oscillator crosses the sliding direction of the oscillator. There is a problem that it is not possible to switch rapidly. Further, the sliding amount of the oscillator for one rotation of the oscillating gear in the four events partitioned by the _two axis lines l ₁ and l ₂ shown in FIG. Is in the direction change region where the spool shaft moves from the forward direction to the backward direction, and the speed of the spool shaft is in the low speed sliding range. Further, in the case of the II event, the spool shaft is a moving region in which the spool shaft moves backward, and the speed of the spool shaft is in a high-speed sliding region as compared with the case of the I event. In the case of the III event, the spool shaft is in the direction change region from the backward movement to the forward movement,
The spool shaft speed is in the low speed sliding range. Further, in the IV event, the spool shaft is a moving area in which the spool shaft moves forward, and is in the high-speed sliding area as in the case of the II event. Therefore, there is a problem that the moving speed of the spool shaft is higher in the II event and the IV event which are the high-speed sliding areas than in the low-speed sliding area of the I-event and the III-event moving speed.
Therefore, there is a problem that the fishing line is not evenly wound around the spool due to the speed difference, and the fishing line is entangled.

An object of the present invention is to provide a fishing reel equipped with a sliding mechanism capable of solving the above problems.

The tube shaft 4 is provided with a rotating body 5, and is configured to be able to rotate integrally with the rotation of the tube shaft 4. A spool shaft 6 is slidably passed through the tube shaft 4 in the axial direction, and a spool 7 is fixed to the tip of the spool shaft 6. An oscillator 8 is fixed to the base end of the spool shaft 6 with a screw 9.

On the other hand, a reduction gear 3b is integrally formed on the handle shaft 3, and the reduction gear 3b is oscillatingly provided on a protrusion 1a integrally formed on the reel unit 1 so as to be rotatable. Is meshed with. A rotary plate 11 is provided between one side of the oscillator gear 10 and the oscillator 8.
Is provided. As shown in FIG. 2, a swing pin 11a is provided on one end side of the rotating plate 11 so as to project. The swing plate 11a engages with the side surface of the oscillating gear 10 to cause the rotating plate 11 to oscillate. It is provided so as to be swingable with respect to 10. Further, guide pins 11b and 11c are provided on both side surfaces on the other end side of the rotary plate 11 so as to project.

Here, the cam groove 1b is formed so as to intersect with the reciprocating movement direction of the spool shaft 6, and as shown in FIG. 3, the elliptical main shaft is formed so as to be inclined with respect to the reciprocating movement direction of the spool shaft 6. There is. Further, the guide pin 11c is provided with a vertical groove 8 formed in the vertical direction of the oscillator 8.

The operation of the fishing reel thus configured will be described. First, by rotating the handle 2, the handle shaft 3 rotates. This handle shaft 3
Rotation of the pipe shaft 4 through the main gear 3a and the pinion 4a.
Rotates, which in turn rotates the rotating body 5.

On the other hand, the rotation of the handle shaft 3 causes the oscillating gear 10 to rotate via the reduction gear 3b. At this time, as shown in FIG. 3, among the four events partitioned by the _two main shafts l ₁ and l ₂ , in the I event, the spool shaft 6 moves from the forward movement to the backward movement. The speed of the spool shaft 6 is in the low speed sliding range. In the case of the II event, the spool shaft 6 is a moving region in which the spool shaft 6 moves backward, and the speed of the spool shaft 6 is I.
Compared to the case of the event, it is in the high-speed sliding area. Further, in the III event, the spool shaft 6 is in the direction change region from the backward movement to the forward movement, and the speed of the spool shaft 6 is in the low speed sliding region. Further, in the IV event, the spool shaft 6 is a moving region in which the spool shaft 6 moves in the forward direction, and is in the high-speed sliding region similarly to the II event.

Therefore, in the reciprocating movement of the spool shaft 6 which is ideally in a state where all the moving speeds are in the constant speed state, in the I event and the III event which are the low speed sliding range, the oscillating gears are used. 10 is a mechanism for accelerating the sliding speed per rotation angle, and in the high-speed sliding range of the II event and the IV event, it is a mechanism for reducing the sliding speed per rotation angle of the oscillating gear 10. desirable.

In the configuration of this embodiment as described above, the oscillating gear 1 is used for the I event and the III event.
The sliding speed per rotation angle of 0 is accelerated and the spool shaft 6
Reciprocating movement of the oscillating gear 10 is accelerated and the sliding speed per rotation angle of the oscillating gear 10 is reduced in the II and IV events,
The mechanism is such that the reciprocating movement of the spool shaft 6 is decelerated.

That is, when the II event includes the guide pin 11c engaged with the vertical groove 8a of the oscillator 8, the guide pin 11 is rotated with the clockwise rotation of the oscillating gear 10 in FIG.
b tries to rotate in the counterclockwise direction in the figure (direction of arrow A in the figure) with respect to the swing pin 11a. When viewed in the circumferential direction, this movement is a movement in the counterclockwise direction (the direction of arrow B in the figure), and deceleration is correspondingly made. Therefore, the movement amount of the oscillator 8 from the point a indicated by the broken line in FIG. 4 to the point b can be reduced, and it can approach the constant velocity motion line indicated by the solid line in FIG.

Even in the IV event in the same high-speed sliding range, the movement amount of the oscillator 8 from the point c to the point d can be similarly reduced, and the line of constant velocity can be approximated.

Next, in the III event, the flute 8 of the oscillator 8 is
The case where there is the guide pin 11c engaged with a will be described. At this time, with the clockwise rotation in FIG. 2, the guide pin 11b tries to rotate in the clockwise direction in the figure (direction of arrow C in the figure) with respect to the swing pin 11a. When viewed in the circumferential direction, this movement is a clockwise movement (arrow D direction in the drawing), and the acceleration is correspondingly made. Therefore, FIG.
It is possible to increase the movement amount of the oscillator 8 from the point b indicated by the broken line to the point c, and it is possible to approach the constant velocity motion line indicated by the solid line in FIG.

Even in the I event, which is in the same low speed sliding range, the amount of movement of the oscillator 8 from the point d to the point a can be similarly increased, and can approach the constant velocity motion line.

As described above, the spool shaft 6 can be reciprocally moved in a state of approaching the uniform velocity motion as much as possible, so that the fishing line can be uniformly wound around the spool 7. Second Embodiment FIG. 5 is a view showing the relationship between the oscillating gear 10 and the rotary plate 11 of the second embodiment of the fishing reel according to the present invention, when the spool shaft 6 is at the rear end position. Further, FIG. 6 is a VI-VI arrow view in FIG. 5, and FIG. 7 is VI in FIG.
FIG. 8 is a view as seen from the direction of arrow I-VII, and FIG. 8 is a view showing the relationship between the oscillating gear 10 and the rotary plate 11 when the spool shaft 6 is located in the intermediate portion.

This embodiment is the same as the above-mentioned embodiment, but the guide pin 11c is engaged with the longitudinal groove 8a of the oscillator 8 formed on the rotary plate 11 and the guide pin is engaged with the cam groove 1b of the reel unit 1. The case where the guide pin 11c is formed at the same position as the guide pin 11b has been described.
In contrast, the oscillating gear 10 is deviated by a predetermined angle α in the circumferential direction. In such a configuration, by adjusting the amount of pin deviation in the circumferential direction of the oscillating gear 10, the ratio of the major axis to the minor axis of the cam groove 1b can be adjusted, and the cam groove 1b can be rounded. The guide pin 1 engaging with the cam groove 1b can be formed into an elliptical shape close to
Since the drive transmission resistance between the cam groove 1b and the cam groove 1b can be reduced, the cam groove 1b and the guide pin 11 engaged with the cam groove 1b can be reduced.
It is possible to prevent abrasion damage with b and to enable smooth and light sliding movement of the spool.

The guide pin 11c may be offset from the guide pin 11b in the radial direction of the oscillating gear 10 by a predetermined length. In the case of such a configuration, the sliding amount of the spool 7 can be arbitrarily adjusted by changing and adjusting the deviation distance of the guide pin 11b in the radial direction with respect to the rotation shaft core of the oscillating gear 10.

Further, by biasing the guide pin 11b larger than the major diameter of the cam groove 1b, a spool sliding amount longer than the diameter of the oscillating gear 10 can be secured, so that the oscillating gear 10 and the cam groove 1b having a small diameter allow the spool 7 to move. A large amount of sliding can be secured, which in turn can reduce the size and weight of the reel unit 1.

Since it can be formed in a recessed elliptical shape, the drive transmission resistance between the guide pin and the cam groove can be reduced, and the wear and damage between the cam groove and the guide pin can be prevented, and it is smooth and light. The sliding movement of the spool can be performed. Since the intersecting direction of the cam groove with respect to the sliding direction of the spool can be adjusted by the position of the swing axis of the guide pin, the oscillating gear can be provided close to the handle shaft, and the reel body shape and parts arrangement The degree of freedom in design is increased, and the size and weight can be reduced.

By adjusting the amount of sliding motion with respect to the guide pin, the amount of reciprocating movement can be adjusted according to the width of the thread winding body of the spool attached to the front end of the spool shaft. . Further, the moving speed of the oscillator, that is, the spool can be partially changed and adjusted by changing the inclination angle of the elongated hole formed in the link or by bending the elongated hole.

According to the present invention, which is configured as described above, the displacement amount of the spool can be arbitrarily adjusted by adjusting the deviation distance of the pin in the radial direction with respect to the rotation axis of the oscillating gear. It is possible to deal with this by simply changing the rotary plate according to the size of the width of the thread winding portion of the spool. Further, by displacing the pin larger than the major axis of the cam groove, it is possible to secure the movement amount of the spool longer than the diameter of the oscillating gear, and it is possible to obtain the large movement amount of the spool by the oscillating gear of small diameter and the cam groove. As a result, the reel body can be reduced in size and weight.

According to the present invention having the above-mentioned structure, the ratio of the major axis to the minor axis of the cam groove can be adjusted by adjusting the amount of pin deviation in the circumferential direction of the oscillating gear. Since the cam groove can be formed in an elliptical shape close to a circle or a large depression in the minor axis direction, the drive transmission resistance between the pin engaging the cam groove and the cam groove can be reduced.
