Abstract

PROBLEM TO BE SOLVED: To enable a fishing line to be smoothly guided to a line roller in a fishing line-guiding mechanism. SOLUTION: A bail arm 34 has a bail 41 connecting a first support 40 to a second support 42, a line roller 44 supported on a fixed shaft and a fixed shaft cover 46 partly covering the fixed shaft. The bail 41 is placed in a convexly outward bent state in the outside of the periphery of a spool 4. The shortest distance R between a contacting part 41a on the side of a fishing line-guiding part of the bail 41 near to the line roller 44 and the shaft axis X of a spool shaft 15 is formed so as to be gradually smaller as it goes from the bail part 41a to the line roller 44. The decrease proportion in the shortest distance R between a part ranging from a coupling part of the bail 41 with the cover 46 to the line roller 44 and the spool shaft axis 15 is set larger than that in a region ranging from the bail part 41a to the vicinity of the coupling part.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a fishing line guide mechanism,
In particular, the present invention relates to a fishing line guide mechanism of a spinning reel that is swingably mounted on a tip of a pair of rotor arms in a line guiding posture and a line releasing posture and guides a fishing line to a spool.

[0002]

2. Description of the Related Art A spinning reel is provided with a fishing line guide mechanism for guiding a fishing line to a spool. The fishing line guide mechanism is mounted on the tip of a pair of rotor arms, rotates with the rotor, and is swingably provided between a line releasing position and a line winding position. The fishing line guide mechanism includes a pair of bail support members, a fixed shaft having one end fixed to the tip of one bail support member, a fixed shaft cover fixed to the other end of the fixed shaft, and a fixed shaft cover. It has a bale with one end attached and a line roller. The other end of the bail is attached to the other end of the pair of bail support members. One end of the bail is bent and inserted and fixed to the side top of the fixed shaft cover. The line roller is rotatably supported on the fixed shaft via a bearing between the fixed shaft cover and the bail support member.

In a spinning reel having such a fishing line guide mechanism, when winding a fishing line onto a spool, the bail is swung toward the line winding position and the handle is turned. Then, the fishing line is guided by the bail, guided to and contacted with the outer peripheral surface of the line roller via the fixed shaft cover. Then, the fishing line is guided by the line roller, changes its direction, and is wound around the outer periphery of the spool.

[0004]

In the conventional fishing line guide mechanism, the fishing line is directly guided to the line roller by the bail, so that the fishing line can be prevented from being caught at the joint between the fixed shaft cover and the bail. However, since the bail is bent almost at a right angle near the fixed shaft cover, if the processing accuracy of the bent part is poor, the distance from the fishing line contact part on the spool to the bail's fishing line guide side contact part at the bent part is a line. The length of the fishing line gradually increases toward the roller side, where the fishing line may be caught and the line may be entangled.

An object of the present invention is to make it possible for a fishing line guide mechanism to smoothly guide a fishing line to a line roller.

[0006]

A fishing line guide mechanism according to a first aspect of the present invention is a spinning device which is swingably mounted at a tip of a pair of rotor arms of a rotor in a line guiding position and a line releasing position to guide a fishing line to a spool.

Have been.

In this fishing line guide mechanism, for example, when the handle is rotated to bring the bail into the line winding position, the fishing line comes into contact with the fishing line guide side of the bail, and the fishing line is guided from the bail to the line roller via the fixed shaft cover. . Then, the fishing line is guided by the line roller, the direction thereof is changed, and the fishing line is wound around the outer periphery of the spool. During the movement of the fishing line from the bail to the fixed shaft cover, since the shortest distance between the fishing line guide side contact portion of the line roller side portion of the bail and the spool shaft core gradually decreases from the bail toward the line roller, The distance from the fishing line contact portion on the spool to the fishing line guide-side contact portion of the veil is gradually reduced, so that the fishing line is less likely to be caught. Therefore, the fishing line can be smoothly guided from the bail to the line roller.

A fishing line guide mechanism according to a second aspect of the present invention is the fishing line guiding mechanism of the first aspect, wherein in the line guiding posture, the shortest distance between the fishing line guiding side contact portion of the line roller side portion of the fixed shaft cover and the spool shaft center is equal to the bale length. 2. The fishing line guide mechanism for a spinning reel according to claim 1, wherein the fixed shaft cover is formed so as to gradually decrease from the line roller side.

In this case, the shortest distance between the fishing line guide side contact portion of the line roller side portion of the fixed shaft cover and the spool shaft core is gradually reduced from the bail toward the line roller, so that the fishing line is further caught. It becomes difficult. The fishing line guide mechanism according to a third aspect of the present invention is the fishing line guide mechanism according to the first or second aspect, wherein a reduction ratio of a shortest distance between the spool shaft center and a portion from a vicinity of a joint between the bail and the fixed shaft cover to the line roller is from the bale. It is larger than the decrease rate of the shortest distance to the vicinity of the joint.

In this case, even if there is a delicate step at the joint between the bail and the fixed shaft cover, the rate of decrease becomes large there, and the fishing line jumps over the joint with force and is guided smoothly to the line roller. . A fishing line guide mechanism according to a fourth aspect of the present invention is the fishing line guide mechanism according to any one of the first to third aspects, wherein the fixed shaft and the fixed shaft cover are integrally formed by cutting.

In this case, since the fixed shaft and the fixed shaft cover are integrated, the strength of the fixed shaft is further increased. In addition, since it is cut, the surface is smooth and finished with high accuracy. A fishing line guide mechanism according to a fifth aspect of the present invention is the fishing line guide mechanism according to any one of the first to fourth aspects, wherein the line roller is rotatably supported on the fixed shaft by two rolling bearings arranged at an interval in the axial direction on the fixed shaft. Have been.

In this case, since the line roller is supported by the two rolling bearings, the rotation of the line roller becomes smooth, and the winding resistance when winding the fishing line is reduced. A fishing line guide mechanism according to a sixth aspect of the present invention is the fishing line guide mechanism according to any of the first to fifth aspects, further comprising a synthetic resin collar member interposed between the fixed shaft cover and the line roller.

In this case, since the collar member is interposed between the fixed shaft cover and the line roller, the fishing line guided from the fixed shaft cover to the line roller is less likely to bite between the two.

Bale arm 3 for unreeling during casting
4 is moved to the thread release position. As a result, the first and second bail support members 40 and 42 swing. As a result, the fishing line is sequentially fed out from the leading end side of the spool 4 by its own weight.

When winding the line, the bail arm is returned to the line winding position. This is automatically performed by the operation of a bale reversing mechanism (not shown) when the handle 1 is rotated in the line winding direction. The rotational force of the handle 1 is transmitted to the pinion gear 1 via the handle shaft 10 and the master gear 11.
2 is transmitted. The torque transmitted to the pinion gear 12 is transmitted from its front portion to the rotor 3 and is also transmitted to the oscillating mechanism 6 by the intermediate gear 23 meshing with the pinion gear 12. As a result, the rotor 3 rotates in the line winding direction and the spool 4 reciprocates back and forth.

The fishing line in contact with the bail 41 at the beginning of the winding is guided by the bail 41 to the fixed shaft cover 46. The fishing line guided by the fixed shaft cover 46 is guided by the line roller 44, the direction is changed by the line roller 44, and the line is wound around the outer periphery of the spool 4. In this spinning reel, the shortest distance R between the fishing line guide side contact portion 41a on the line roller 44 side of the bail 41 and the spool axis X gradually decreases from the bail 41 toward the line roller 44. The fluctuation of the distance with the distance disappears, and the fishing line is hardly caught. Therefore, the fishing line can be smoothly guided from the bail 41 to the line roller 44. Further, the decreasing rate of the shortest distance R between the portion from the vicinity of the joint between the bail 41 and the fixed shaft cover 46 to the line roller 44 and the spool axis X is smaller than the decreasing rate of the shortest distance R from the bale to the vicinity of the joint. Since the fishing line is large, the fishing line jumps over the joining portion with momentum, so that the fishing line can be smoothly guided to the line roller 44.

[Other Embodiments] (a) In the above embodiment, a front drag type spinning reel was described as an example, but a rear drag type spinning reel, a spinning reel having no drag, or a lever drag type spinning reel. The present invention can be applied to all spinning reels.

(B) In the above embodiment, the fixed shaft 43 and the fixed shaft cover 46 are formed integrally, but they may be formed separately. (C) In the above embodiment, the bail arm 34 is provided with the arch portion 45, but the present invention can be applied to a spinning reel having no arch portion 45.

[0034]

According to the present invention, during the movement of the fishing line from the bail to the fixed shaft cover, the shortest distance between the fishing line guide side contact portion of the line roller side portion of the bail and the spool shaft center is changed from the bail to the line roller. Since the distance gradually decreases toward the spool, the distance from the spool does not increase or decrease, and the fishing line is less likely to be caught. Therefore, the fishing line can be smoothly guided from the bail to the line roller.
