BACKGROUND OF THE INVENTION
The present invention relates to a fishing line guide mechanism, and more particularly to a spinning reel fishing line guide mechanism that is swingably attached to the tip of a pair of rotor arms of a rotor so as to be swingable between a line guiding position and a line releasing position and guides a fishing line to a spool.
[0002]
[Prior art]
The spinning reel is provided with a bale arm (an example of a fishing line guide mechanism) that guides the fishing line to the spool. The bail arm is swingably attached to the tip of the rotor arm in a yarn guiding posture and a yarn releasing posture, and a pair of bale support members swingably attached to a pair of rotor arms, And a guide roller attached to the tip of the bail support member. The guide roller is rotatably supported by a fixed shaft that is cantilevered by one bail support member. A fixed shaft cover is fixed to the tip of the guide roller, and one end of the bail is fixed to the fixed shaft cover. The other end of the bail is fixed to the other bail support member.
[0003]
In the conventional bale arm having such a configuration, in the case of a large spinning reel for fishing a fish that is strongly pulled, the strength is not sufficient if the fixed shaft is only cantilevered by one bail support member. . Thus, a large spinning reel is known that supports both ends of a fixed shaft (Japanese Utility Model Laid-Open No. 3-117462). In the bail arm disclosed in the publication, a bridging portion extending from the tip of the bail support member toward the fixed shaft cover and a ring portion integrally formed at the tip of the bridging portion are provided, and a fixed shaft is provided on the ring portion. By fitting the cover, the other end of the fixed shaft is supported and both ends of the fixed shaft are supported.
[0004]
[Problems to be solved by the invention]
In the conventional fishing line guide mechanism, an annular groove or protrusion is formed between the fixed shaft cover and the ring portion, and the fishing line guided from the bale may be caught or caught in this portion. In addition, the fixed shaft cover is only fixed to the bail support member at the center by bolts also used as the fixed shaft, and is not prevented from rotating. Therefore, the position of the bail is not stable, and the rotation balance of the entire rotor is balanced. Not stable.
[0005]
An object of the present invention is to prevent a fishing line from being caught or caught in a fishing line guide mechanism capable of supporting both ends of a fixed shaft.
Another object of the present invention is to stabilize the rotational balance of a rotor in a fishing line guide mechanism capable of supporting both ends of a fixed shaft.
[0006]
[Means for Solving the Problems]
A fishing reel guide mechanism for a spinning reel according to a first aspect of the present invention is a mechanism that guides a fishing line to a spool, which is swingably mounted on a tip of a pair of rotor arms of a rotor in a swing guide posture and a release posture. A bail support member, a fixed shaft, a line roller, an arch portion, a fixed shaft cover, and a bail. The pair of bail support members are members that are swingably attached to the tip of the rotor arm. The fixed shaft is a shaft having one end fixed to one of a pair of bail support members. The line roller is a roller that is rotatably supported by a fixed shaft and has a guide portion that guides a fishing line on a circumferential surface. The arch portion is formed integrally with the bridge portion extending from the tip of one bail support member to the other end of the fixed shaft through the outside of the line roller, and supports the other end of the fixed shaft. And a ring-shaped shaft support portion. The fixed shaft cover is a cover that is provided at the other end of the fixed shaft at a distance from one bail support member, covers the shaft support portion from the outside, and extends to a position overlapping the end portion of the line roller. The bail is fixed to the other end of the bale support member and the fixed shaft cover, and is arranged so as to be convexly curved outward in the circumferential direction of the spool, and guides the fishing line to the line roller through the fixed shaft cover. is there.
[0007]
In this spinning reel fishing line guide mechanism, when returning from the line releasing position to the line guiding position during casting or the like and rotating the rotor, the fishing line is guided to the line roller through the fixed shaft cover while being in contact with the bale, and further to the spool. Guided and wrapped. Since this fixed shaft cover extends from the outside to the position that covers the shaft support portion and overlaps the end portion of the line roller, the fishing line does not contact the shaft support portion. For this reason, by smoothing the line contact portion of the fixed shaft cover, the fishing line is less likely to be caught or bitten when guided from the bail to the line roller.
[0008]
A spinning reel fishing line guide mechanism according to a second aspect of the present invention is the mechanism according to the first aspect, wherein the bridging portion is connected to the pivotal support portion at the outer peripheral surface of the pivotal support portion, and the fixed shaft cover includes the pivotal support portion as the bridging portion. The connection portion is substantially entirely covered except for the connecting portion, and the connecting portion is positioned in the rotational direction by the bridging portion. In this case, since the bridging portion is connected to the outer peripheral portion of the shaft support portion, and the fixed shaft cover is positioned in the rotational direction by the bridging portion at this connection portion, the fixed shaft cover does not rotate around the axis. The rotation balance of the rotor is stabilized. In addition, since the fixed shaft cover substantially covers the entire circumference of the shaft support except for the connecting portion, the fishing line guided from the fixed shaft cover to the line roller is less likely to be caught or bitten.
[0009]
A spinning reel fishing line guide mechanism according to a third aspect of the present invention is the mechanism according to the first or second aspect, wherein the bridging portion is forward of the fixed position of the fixed shaft toward the other end of the fixed shaft in one bail support member. It extends. In this case, since the bridging portion is disposed on the side opposite to the surface on which the fishing line is guided, the bridging portion is not obstructed when guiding the fishing line to the line roller.
[0010]
A spinning reel fishing line guide mechanism according to a fourth aspect of the present invention is the 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. Moreover, since it is cut, the surface is smooth and accurate.
[0011]
A spinning reel fishing line guide mechanism according to a fifth aspect of the present invention is the mechanism according to any one of the first to fourth aspects, wherein the line roller is fixed to the fixed shaft by two rolling bearings arranged on the fixed shaft at an interval in the axial direction. It is supported rotatably. 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.
[0012]
A spinning reel fishing line guide mechanism according to a sixth aspect of the present invention is the mechanism according to any one of the first to fifth aspects, further comprising a synthetic resin color member interposed between the fixed shaft cover and the line roller.

[Reel operation and operation]
In this spinning reel, the bail arm 34 is brought down to the yarn releasing posture when the yarn is fed out during casting or the like. As a result, the first and second bail support members 40 and 42 swing. As a result, the fishing line is fed out in order from the front end side of the spool 4 due to its own weight.
[0029]
When winding the yarn, return the bale arm to the yarn winding posture. This is automatically performed by the operation of a bale reversing mechanism (not shown) when the handle 1 is rotated in the yarn winding direction. The rotational force of the handle 1 is transmitted to the pinion gear 12 via the handle shaft 10 and the master gear 11. The rotational force transmitted to the pinion gear 12 is transmitted from the front part to the rotor 3 and is transmitted to the oscillating mechanism 6 by the intermediate gear 23 that meshes with the pinion gear 12. As a result, the rotor 3 rotates in the yarn winding direction and the spool 4 reciprocates back and forth.
[0030]
The fishing line that contacts the bail 41 at the beginning of winding is guided to the fixed shaft cover 46 by the bail 41. The fishing line guided by the fixed shaft cover 46 is guided by the line roller 44, and the direction of the fishing line is changed by the line roller 44 and wound around the outer periphery of the spool 4.
At this time, since the fixed shaft cover 46 is disposed so as to overlap the line roller 44 and the fixed shaft cover 46 covers the shaft support portion 45b, the fishing line is not easily caught or bitten. In addition, since the collar member 48 is interposed between the fixed shaft cover 46 and the line roller 44, the fishing line is not easily caught between them. Further, since the base end of the fixed shaft 43 is fixed by the both ends support supported by the shaft support portion 45b and the tip end is supported by the support portion 51, the line roller 44 is large as when a large fish is caught. Even if a load is applied, the fixed shaft 43 is firmly supported and hardly bent. For this reason, even if a large load acts, the rotation of the line roller 44 is smooth and the fishing line can be wound up smoothly.
[0031]
[Other Embodiments]

[0032]
(B) In the above-described embodiment, the fixed shaft cover is prevented from rotating at the bridge portion. However, the fixed shaft may be prevented from rotating by the first bail support member, and the fixed shaft cover and the fixed shaft may be further prevented from rotating.
(C) In the embodiment, the fixed shaft and the fixed shaft cover are integrally formed, but may be formed separately.
[0033]
【The invention's effect】
According to the present invention, the fixed shaft cover covers the shaft support portion from the outside and extends to a position overlapping the end portion of the line roller, so that the fishing line does not contact the shaft support portion. For this reason, by smoothing the line contact portion of the fixed shaft cover, the fishing line is less likely to be caught or bitten when guided from the bail to the line roller.
