Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fishing reel having a fishing line parallel winding device.

[0002]

2. Description of the Related Art Conventionally, in a fishing reel, various oscillating mechanisms have been known as a fishing line parallel winding device for winding a fishing line parallel and evenly around a spool. A traverse camshaft having a groove and a slider for holding an engagement claw that engages the cam groove are provided.

[0003] The cam groove of the traverse camshaft has a shape that allows the slider to reciprocate along the traverse camshaft while guiding the engagement claws.

For example, the cam groove disclosed in Japanese Utility Model Laid-Open Publication No. Hei 6-23456 has a wall surface perpendicular to the axis of the traverse camshaft or a wall surface gradually narrowing toward the axis. I have.

[0005]

However, the cam groove having the above-mentioned shape has the following problems.

[0006] The wall surface of the cam groove is swollen toward the center of the cam groove while being twisted toward the bottom of the cam groove. A pressing force from the wall surface of the cam groove acts in a direction crossing the cam groove (that is, a direction in which the engaging claw is inclined in the cam groove). In this state, when the engaging claw approaches the intersection where the cam groove intersects, the engaging claw is inclined in a direction crossing the cam groove due to the pressing force from the wall surface of the cam groove. For this reason, at the intersection of the cam grooves, the ends of the engagement claws come into contact with the ends of the cam grooves, and as a result, problems such as generation of abnormal noise, and wear and loss of the engagement claws and the cam grooves occur. I will.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a fishing line parallel winding device capable of always stabilizing an engagement claw of a slider in a fixed direction. An object of the present invention is to provide a fishing reel.

[0008]

In order to achieve the above object, a fishing reel according to the present invention comprises a drive gear that rotates in conjunction with a handle supported on a reel body, and an integral drive gear. A traverse camshaft that is rotatably rotated and has a cam groove formed in a cross shape, and a slider that holds an engagement claw that engages with the cam groove, and slides while guiding the engagement claw with the cam groove. The fishing line is configured to have a fishing line parallel winding device that winds the fishing line in parallel on a spool supported by the reel body by reciprocating the child along a traverse cam shaft. And a holding portion held by the slider, wherein the distal end side of the claw portion is gradually narrowed toward the traverse cam groove, and has a curved surface shape protruding outward on the outer surface thereof. It is characterized by chamfering.

[0009]

According to this, when the pinion 8 is rotated via the drive gear 6 by the rotation operation of the handle 4, the gear 26 meshed with the pinion 8 rotates, and the traverse cam shaft 22 rotates with the rotation of the gear 26. At this time, the engaging claw 28 engaged with the traverse cam shaft 22 moves back and forth with the rotation of the traverse cam shaft 22, and the
4 moves back and forth along the traverse cam shaft 22. As a result, the spool shaft 10 connected to the slider 24 via the set screw 30 can be moved back and forth.

In the fishing reel having the above-described configuration, when the handle 4 is rotated, the rotational motion is transmitted to the pinion 8 via the drive gear 6 to rotate the rotor 12 attached to the pinion 8. Rotate. At the same time, the rotational movement of the handle 4 is transmitted to the spool shaft 10 via the oscillating mechanism 20 to move the spool shaft 10 back and forth. At this time, the fishing line is formed by the spool 12 moving back and forth while the rotor 14 rotates.
It is wound parallel and evenly around the spool 12 via the fishing line guide mechanism 19.

The forward cam groove 32 and the backward cam groove 34 having the following shape are formed so as to intersect at a constant interval. The portions where the forward cam groove 32 and the backward cam groove 34 intersect each other, An intersection 36 is formed. The outward cam groove 32 and the return cam groove 34 are respectively
It is composed of a groove bottom surface 38 and groove side walls 40a and 40b vertically raised from both sides of the groove bottom surface 38 along the radial direction of the traverse cam shaft 22 (FIGS. 5 and 5 showing the groove in an enlarged scale). 6). These groove side walls 40a, 40b
It is formed along the outer periphery of the traverse cam shaft 22 while being twisted, and has two ridge lines 38 a, 3
8b (hereinafter referred to as groove ridge lines) (see FIGS. 5 and 6).

The engaging claw 28 held by the slider 24 moves with respect to the outward cam groove 32 and the backward cam groove 34 while the slider 24 reciprocates along the traverse cam shaft 22. It is configured such that it can always be stably engaged in a certain direction. Specifically, as shown in FIGS. 3 and 4, the engaging claw 28 includes a holding portion 42 for holding the engaging claw 28 on the slider 24, the outward cam groove 32, and the returning cam. The claw portion 44 engages with the groove 34. As shown in FIG. 3B, the claw portion 44 is formed adjacent to the holding portion 42 and has a base end portion 46 having a constant thickness. And a chamfered portion 48 whose width gradually decreases in the direction of extension from the base end portion 46 and whose outer surface protrudes outward. As described above, the claw portion 44 gradually narrows from the base end portion 46 having a constant thickness toward the distal end side,
The shape is changed to a chamfered portion 48 which is convex toward the outside, and the shape-changed portion (the base end portion 46 and the chamfered portion 48
A transition portion P that transitions from the base end portion to the chamfered portion is defined at the boundary between the base portion and the chamfered portion.

As shown in FIG. 4, the chamfered portion 48 has two tapered surfaces 48a and 48b having two curved surfaces (in the present embodiment, circular arcs) continuously narrowing from the base end portion 46. It has two flat surfaces 50 arranged on both sides of the tapered surfaces 48a and 48b in parallel with each other, and the chamfered portion 4 is formed by these tapered surfaces 48a and 48b and the two flat surfaces 50.
8 is defined. In the center of the tip of the chamfered portion 48, the outward cam groove 32 and the backward cam groove 3 are provided.
An engaging surface 52 that can smoothly slide on the groove bottom surface 38 of the fourth groove 4 is formed. The engaging surface 52 is formed in a concave semicircular shape that matches the curvature of the groove bottom surface 38. . In addition,
The two ridge lines 52a, 52b are provided at both ends of the engaging surface 52 by the engaging surface 52 and the two tapered surfaces 48a, 48b.
(Hereinafter referred to as engagement ridges), and the tops of these engagement ridges are located in the base end portion 46 (see FIG. 3A).

In such a configuration, when the claw portion 44 of the engagement claw 28 is engaged with the outward cam groove 32 and the backward cam groove 34, the tapered surfaces 48a, 4
The ridge lines 52a and 52b defined by the outer shape of the outer groove 8b, that is, the outer shape that gradually becomes narrower toward the tip and becomes convex outward, are groove ridge lines 38a and 38b of the cam groove.
Line contact. That is, the chamfer 4
8 have their ridge lines 52a, 52b
b has a shape such that when the traverse camshaft 22 rotates, it comes into line contact with the groove ridge lines 38a and 38b of the cam groove. In FIG. 4, the external shape of the conventional claw portion is indicated by a two-dot chain line.

Next, the operation of the oscillating mechanism 20 configured as described above will be described with reference to FIGS. The engaging claw 28 of the slider 24 is connected to the forward cam groove 32 and the backward cam groove 3 of the traverse cam shaft 22.
4 are the same as each other, the following description will be made on the case where the engaging claw 28 of the slider 24 is moved forward along the outward cam groove 32 of the traverse cam shaft 22. explain.

FIGS. 5A and 5B show the claws 4 of the slider.
4 shows a state in which No. 4 is engaged with the outward cam groove 32 of the traverse cam shaft 22. When the traverse cam shaft 22 rotates in the direction of arrow R in this state, the claw portion 44
Then, it slides while being guided by, and eventually arrives near the intersection 36 (see FIG. 7).

In the meantime, the pawl 44 is provided with the outward cam groove 32.
The load from the groove side walls 40a and 40b continues to act. Specifically, of the two engagement ridge lines 52a and 52b defined by the engagement surface 52 formed on the chamfered portion 48, a region on the side of the engagement ridge line 52a on the taper surface 48a side (FIG. b), a load is applied from the groove side wall 40a (specifically, the groove ridge line 38a of the groove bottom surface 38), and at the same time, the taper surface 48b on the other end side of the chamfered portion 48 is located above the tapered surface 48b. The region extending to the outer surface of the portion 46 is
The load from b acts.

That is, when the traverse camshaft 22 rotates, the pawl 44
Is that the region on the advancing side of the engaging ridge line 52a makes line contact with the groove ridge line 38a of the groove side wall 40a, and the tapered surface 48b of the chamfered portion 48
The region from to the outer surface of the base end 46 above it is
It moves in the groove 32 while contacting the groove side wall 40b.

When the claw portion 44 slides along the outward cam groove 32 while maintaining this state, and the front end side of the chamfered portion 48 approaches the intersection portion 36 from the state shown in FIG. (See FIG. 8), the contact state with the groove ridge line 38a is continuously released from the tip end side of the engagement ridge line 52a.
However, the above-described engagement ridge 52a and groove ridge 38a
The front end of the chamfered portion 48 crosses the intersecting portion 36 and enters the continuously formed groove 32, and the front end of the engaging ridge 52a is again connected to the cam groove 3 which is continuous.
It is maintained until it contacts the second groove ridge line 38a (see FIG. 9).

As a result, the tip side of the claw portion 44 is
8B, when the leading end side of the engagement ridge line 52a is disengaged from the groove ridge line 38a of the cam groove 32, the arrow R1 in FIG.
(I.e., a force for tilting the claw portion 44 in the crossing portion 36) as shown in FIG.
Since the rear side of “a” maintains the line contact with the groove ridge line 38a, the amount of inclination of the tip of the chamfered portion 48 in the direction of the arrow R1 in the intersection 36 can be reduced. That is, the tip of the chamfered portion 48 has an extremely small inclination amount in the direction of the arrow R1 within the intersection portion 36, so that the intersection portion 3
6 can be advanced without contacting the end 32a of the next outward cam groove 32. As a result, the claw 44
Can be always smoothly slid when crossing the intersection along the outward cam groove 32.

The engaging ridge line 52b also comes into line contact with the groove ridge line of the cam groove 34 in the return cam groove 34, so that the claw 44 always slides smoothly even when it crosses the intersection 36. can do.

FIG. 6B shows the structure of a conventional claw (two-dot chain line in FIG. 4). In the conventional configuration, the distal end side of the claw portion 44 has an outer shape that gradually becomes narrower toward the distal end, and has a chamfered shape that is convex outward as in the present embodiment. Since it is not formed, the ridge line defined by the engagement surface 52 shown in FIG. 4 does not make line contact with the groove ridge line 38a of the cam groove 32, and maintains the contact state only at the extremely short portion Q.
For this reason, when the tip side of the claw portion 44 enters the intersection as shown in FIG. 8, there is no longer a portion for supporting the rotation in the R1 direction as shown in FIG. This makes it easier to come into contact with the end portion 32a of the nozzle 32, resulting in generation of abnormal noise, rattling, or a problem such as wear or loss of the cam groove.

As described above, according to the oscillating mechanism 20 of the present embodiment, the engaging claw 28 (claw portion 44) of the slider 24 is always in the forward cam groove 32 and the backward cam groove 34. It can be stabilized in a certain direction.

The present invention is not limited to the configuration of the above-described embodiment, but can be variously modified as follows.

FIGS. 10 and 11 are views showing another embodiment of the engaging claw 28. FIG. As described above, the engagement claws 28
It is sufficient that the portion extending from the base end portion 46 has an outer shape in which a ridge line is formed so as to be in line contact with the groove ridge line at the bottom of the cam groove. In the configuration shown in FIG.
A chamfered portion 48 having a plurality of circular arcs 48e and 48f having different radii of which the outer surface is convex outward is formed while gradually narrowing in width in the extending direction from the base end portion. ing. In the above-described embodiment, the chamfered portion is formed by one arc. However, even if the chamfered portion is formed by a plurality of arcs as in this embodiment, the engagement ridges 52a, 52
b can be brought into line contact with the groove ridge line of the traverse cam groove. In this case, it is preferable that the radius of the arc 48f on the front side be smaller than the radius of the arc 48e on the side close to the holding portion 42.

In the above-described embodiment, the arc-shaped portions 48a, 48e, 48 formed in the chamfered portion 48 are provided.
f is an engagement ridge 52a defined by the engagement surface 52,
The radius of the traverse cam groove is preferably set to 1 mm or more and 20 mm or less so that the ridge 52b can contact the groove ridge line of the traverse cam groove in a predetermined range.

In the above-described embodiment, the spinning reel is exemplified as the fishing reel. However, the present invention can be applied to a traverse mechanism of a dual bearing reel.
