Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a spinning reel for fishing.

[0002]

2. Description of the Related Art Generally, a spinning reel for fishing has a reel body, a leg extending from the reel body, and a rod mounting portion formed at an end of the leg and mounted on a fishing rod. . A handle shaft to which the handle is fixed is rotatably supported in the reel body. A drive gear is fixed to the handle shaft, and the drive gear meshes with a tubular pinion gear extending in a direction perpendicular to the handle shaft and rotatably supported by the reel body. Further, a rotor is integrally attached to a tip portion of the pinion gear, and a spool shaft extending in a direction perpendicular to the handle shaft passes through the pinion gear.
In this case, the spool shaft is arranged concentrically with the pinion gear, and can move back and forth along a direction orthogonal to the handle shaft. Also, a spool around which the fishing line is wound is attached to the tip of the spool shaft.

[0003] In the form of a spinning reel in which the handle can be replaced on the left and right, the handle shaft is arranged such that both ends to which the handle is fixed face the left and right sides of the reel body.
It extends so as to intersect with the spool shaft in the reel body. Further, the handle shaft has a hollow structure, and the handle is removably attached to the handle shaft by inserting and fixing the handle shaft portion into the inner hole of the handle shaft. .

[0004]

When the handle shaft intersects the spool shaft so as to cross the spool shaft, the axis of the spool shaft inevitably extends from the handle shaft in the longitudinal direction of the reel body. (Extending direction of the leg). However, when this offset amount is large, several problems as described below occur.

That is, if the offset amount between the two shafts becomes large, the vertical dimension of the reel body becomes large, so that the spool is largely separated from the rod mounting portion of the leg, and the spool is wound around the spool. It is difficult to sum the turned fishing line.

When the offset amount between the two shafts increases, the transmission efficiency of the rotational torque from the drive gear to the pinion gear also deteriorates. That is, the more the axis of the spool shaft is offset from the axis of the handle shaft in the longitudinal direction of the reel body, the more the pinion gear and the drive gear of the handle shaft concentric with respect to the spool shaft are in their contact positions ( The angle formed by the tangents at the meshing position increases, and the rotational force of the drive gear acting on the pinion gear in the direction of rotation decreases (the rotational torque of the drive gear is not efficiently transmitted to the pinion gear). Therefore, the rotation operation of the handle becomes heavy.

That is, in a structure in which the handle shaft intersects the spool shaft so as to cross the spool shaft, it is desirable that the offset amount between the handle shaft axis and the spool shaft center be as small as possible.

As a method of reducing the offset amount, it is conceivable to set the outer diameter of the spool shaft or the handle shaft to be small and to narrow the gap between the spool shaft and the handle shaft. However, in the conventional configuration, the handle shaft has a hollow structure, and the handle shaft is inserted into the handle shaft, so that the handle shaft has a small diameter while maintaining sufficient strength of the handle shaft. It is difficult to achieve this. On the other hand, since the spool shaft must move forward and backward while supporting the spool at the tip, it is necessary to have a predetermined strength, and it is practically impossible to make it smaller than conventional dimensions.

As disclosed in Japanese Patent Application Laid-Open No. Hei 8-205723, if the outer diameter of the drive gear is increased, some of the problems caused by the offset can be eliminated. That is, if the outer diameter of the drive gear is increased, even if the offset amount between the two shafts is large, it is possible to suppress the deterioration of the transmission efficiency of the rotational torque from the drive gear to the pinion gear to some extent. However, in this case, the problem that the reel body becomes large in the vertical direction is not solved.

If the handle shaft is formed only on one side of the drive gear and does not intersect with the spool shaft as disclosed in Japanese Utility Model Laid-Open No. 57-102977, such an offset problem does not occur. However, the left and right handlebars cannot be replaced, which is not preferable as a general-purpose reel, and is not sufficient in durability, engagement performance, and strength because of single-axis support.

The present invention has been made in view of the above circumstances. It is an object of the present invention to change the right and left of a handle and to reduce the strength of these two shafts without reducing the strength of the spool shaft and the handle shaft. It is an object of the present invention to provide a fishing spinning reel capable of improving transmission efficiency by reducing an offset amount.

[0012]

In order to solve the above-mentioned problems, a spinning reel for fishing according to the present invention comprises a reel body, a rotor rotatably supported by the reel body, and both sides of the reel body. A handle shaft that is rotatably supported and has a handle detachably attached to the end, a drive gear that is provided on the handle shaft and rotates integrally with the handle shaft, meshes with the drive gear, and applies the rotational force of the drive gear to the rotor. A handle that includes a transmitting pinion gear, a spool shaft extending in the reel body so as to intersect with the handle shaft, and a spool supported by the spool shaft and wound with fishing line by rotation of the rotor, the handle intersecting with the spool shaft The shaft portion is formed as a small diameter portion whose outer diameter is set smaller than other portions of the handle shaft, and at least the small diameter portion has a hollow structure. Form, characterized in that the reinforcing member to the hollow portion of at least the small-diameter portion is interposed.

[0013]

The drive gear 3 has a tubular pinion extending in a direction perpendicular to the handle shaft 2 and rotatably supported on a reel body 1 a via a bearing. The gear 13 is engaged. A rotor 8 provided with a bail 6 and a fishing line guide device 15 is integrally attached to a tip portion of the pinion gear 13.

A spool shaft 9 extending in a direction perpendicular to the handle shaft 2 passes through the pinion gear 13. In this case, the spool shaft 9 is arranged concentrically with the pinion gear 13 and can move back and forth along a direction orthogonal to the handle shaft 2. A spool 10 around which a fishing line is wound is attached to the tip of the spool shaft 9.

The drive gear 3 includes a pinion gear 1.

A worm shaft (traverse camshaft) 19a that rotates while meshing with the worm shaft, and a slider that meshes with the groove of the worm shaft 19a and is attached to the spool shaft 9 so as to be immovable in the axial direction. When the spool shaft 9 is rotated by the rotation operation 5, the spool shaft 9 is reciprocally driven (moved forward and backward) along the axial direction.

In such a configuration, when the handle shaft 5 is rotated by rotating the handle 5, the spool 10 attached to the spool shaft 9 reciprocates back and forth via the oscillating mechanism, and the drive gear The rotor 8 is driven to rotate via the pinion 3 and the pinion gear 13. Therefore, the fishing line guide device 15
, The fishing line is wound evenly.

As clearly shown in FIG. 2, the handle shaft 2 extends so as to intersect with the spool shaft 9 in the reel body 1a so that the handle 5 can be changed between right and left. Specifically, both side portions of the handle shaft 2 are rotatably supported by the reel body 1a via bearings 41 and 42, and both right and left end portions 2b and 2c of the handle shaft 2 to which the handle 5 is fixed are connected to the reel. In order to reach the left and right sides of the main body 1a, they are positioned in openings 50, 50 formed on the left and right sides of the reel main body 1a. In addition, female threads 51 are formed in the openings 50, 50 of the reel body 1 a, and a lid 40 for closing the opening 50 is screwed into the female threads 51.

The details of the handle shaft 2 are shown in FIGS. FIG. 3 shows a state where the handle 5 is attached to the handle shaft 2, and FIG. 4 shows a state where the handle 5 is partially removed from the handle shaft 2.

As shown in the figure, on the outer peripheral surface of the handle shaft 2, an annular concave portion 2 is provided at a substantially central portion crossing the spool shaft 9.
9 are formed. That is, the portion of the handle shaft 2 that intersects with the spool shaft 9 is formed as a small-diameter portion 2a whose outer diameter is set smaller than other portions of the handle shaft 2 including the left and right end portions 2b and 2c. In addition, the annular concave portion 29 is set to a size that can accommodate at least a part of the spool shaft 9 inside thereof. In particular, the outer diameter d of the small diameter portion 2a is 17% or less of the outer diameter D of the drive gear 3 (d / D ≦
0.17).

The handle shaft 2 has a hollow structure. More specifically, the through hole 30 is formed continuously over the entire length of the handle shaft 2, and the inner diameter of the portion 30 b of the through hole 30 located at the small diameter portion 2 a in order to secure the strength of the small diameter portion 2 a of the handle shaft 2. However, it is set smaller than the inner diameters of the portions 30 a and 30 c of the other through holes 30.
Further, a portion 30 of the through hole 30 provided in the left end 2b
