Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to spinning reels .

[0002]

2. Description of the Related Art Generally, a spinning reel has a reel body having a handle, a spool which is attached to the reel body so as to be movable back and forth, and has a fishing line wound around its outer circumference, and a spool which is rotatably supported by the reel body and has the fishing line wound around the spool. And a rotor drive mechanism that transmits the rotation of the handle to the rotor.

The rotor drive mechanism includes a handle shaft on which a handle is non-rotatably and detachably mounted, a face gear fixed to the handle shaft, and a pinion gear meshing with the face gear. Both ends of the handle shaft are rotatably supported by the reel body by bearings and project outward from the bearings. The bearing for supporting the handle shaft is mounted inside a pair of boss portions formed on the reel body so as to project left and right. A rectangular through hole extending in the axial direction is formed in the center of the handle shaft, and the handle can be inserted into the through hole from both ends of the handle shaft. The handle is attached to the handle shaft by screwing a mounting screw attached to the handle from the shaft end opposite to the insertion end. The head of the mounting screw is larger than the diameter of the through hole and is locked to the end of the handle shaft. As a result, the handle can be mounted on either the left or right side of the reel body. The pinion gear is provided on the outer peripheral side of the spool shaft and rotates integrally with the rotor.

In the spinning reel having the rotor driving mechanism configured as described above, the boss portion of the reel body on the side opposite to the side where the handle is mounted is closed by, for example, a cap screwed to the boss portion.

[0005]

In the conventional rotor drive mechanism described above, the handle shaft projects outward from the bearing and the handle is attached to the handle shaft at the shaft end of the handle shaft by a mounting screw. Therefore, when the handle is attached to the handle shaft, the boss portion for supporting the handle shaft needs to be projected outward in order to cover the head of the attachment screw. When the boss portion projects outward in this manner, the fishing line may be caught by the boss portion when the fishing line is loosened. Further, if the protruding boss portion is covered with the cap, foreign matter enters between the boss portion and the cap and is difficult to remove.

An object of the present invention is to allow a handle to be attached to a handle shaft without projecting a boss portion for supporting the handle shaft outward.

[0007]

[Means for Solving the Problems] Spinning according to Invention 1
The reel supports both the handle and the handle so that it can rotate freely.
A boss formed so that at least one of its side portions protrudes inward.
Freely rotatable on the reel body with parts and the front part of the reel body
The rotor is supported by and the front part of the rotor can be moved back and forth.
It is provided with a spool and a rotor drive mechanism.
The rotor drive mechanism includes a handle shaft, a face gear, a pinion gear, and a mounting screw. Both ends of the handle shaft are rotatably supported by the boss through bearings, and at least one of the ends is arranged inside the outer surface of the bearing, and the tip of the handle rotates inward from any end. It has a through hole in the center that can be inserted in a way that cannot be inserted.
The face gear is non-rotatably provided on the handle shaft. In the pinion gear, the face gear is engaged with the rotor so that the rotor cannot rotate. The mounting screw has a head portion having a diameter larger than the diameter of the through hole and a screw shaft portion having a diameter smaller than that of the head portion. It is a screw for attaching.

In this spinning reel , the handle is attached to the handle shaft by inserting the handle into the through hole from one end of the handle shaft and screwing the attaching screw into the handle from the other end. At this time, at least one end of the handle shaft is arranged inside the bearing, so that when the handle is inserted from the other end, at least part of the head of the mounting screw can also be arranged inside the bearing. Therefore, the handle can be attached to the handle shaft without projecting outward the boss portion of the reel body for supporting the handle shaft.

The spinning reel according to invention 2 is invention 1
In the mechanism described in (1), the head has a diameter smaller than the inner diameter of the bearing. In this case, since the head of the mounting screw has a smaller diameter than the bearing, the entire head can be arranged inside the bearing. Therefore, the protrusion of the boss portion can be further suppressed.

A spinning reel according to a third aspect of the invention is the first aspect of the invention.
Alternatively, in the mechanism described in 2, the face gear is formed integrally with the handle shaft. In this case, since the handle shaft and the face gear are integrated, they can be easily manufactured and assembled.

[Reel Operation and Operation] There are times when it is desired to change the mounting position of the handle 1 when fishing. For example, at the time of lure fishing and throwing fishing, the handle 1 is often attached to the left side of the reel body 2 as shown in FIGS. 2 and 4 in order to operate the fishing rod with the dominant arm. At other times, in order to operate the handle 1 with the dominant arm, the handle 1 is often mounted on the right side as shown in FIGS. 1, 3 and 5. The left and right mounting positions of the handle 1 differ depending on personal preference.

When changing the mounting position of the handle 1 from the left position shown in FIG. 4 to the right position shown in FIG. 5, first, the two screws 19a are removed and the shaft cover 19 is removed from the boss portion 17a. Then, the mounting screw 20 is removed, and the handle 1 is pulled out from the left end of the handle shaft 10 in FIG. After pulling out the handle 1, the two screws 19a are removed and the perforated cover 19b is also removed from the boss 17b. Then, attach the removed perforated cover 19b to the boss 17a with two screws 19a.
Install by. Next, the shaft portion 1c of the handle 1 that is pulled out is provided with a perforated cover 19 from the right end of the handle shaft 10 in FIG.
Insert through b and insert into the through hole 10a. Then, the mounting screw 20 is screwed into the shaft portion 1c from the boss portion 17b on the left side of FIG. 5, and the handle 1 is mounted on the handle shaft 10. Finally, the shaft cover 19 is attached to the boss 17a with two screws 19a to cover the boss 17a. The handle 1 is now mounted on the right side as shown in FIG.

Here, when the handle 1 is mounted on the left side as shown in FIG. 4, since the boss portion 17a does not project to the outside, the reel body 2a has a smooth surface and the fishing line is hard to be caught. In addition, a new design can be obtained.

At the time of casting, the bail arm 44 is reversed to the line releasing posture with the handle 1 attached to the left position shown in FIG. Accordingly, the first bail support member 40
And the 2nd bail support member 42 rocks. In this state, cast the fishing rod while hooking the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously due to the weight of the tackle. In this state, when the handle 1 is rotated with the left hand in the line winding direction, the rotor driving mechanism 5 rotates the rotor 3 in the line winding direction, the bail arm 44 is returned to the line guiding posture by the bale reversing mechanism 46, and the fishing line is spooled. It is wrapped around 4.

[Other Embodiments] ( a ) The head portion 20a of the mounting screw 20 does not have to have a small diameter entirely, and a portion thereof may have a diameter smaller than the inner diameter of the bearing 16a. That is, even if a mounting screw having a tapered shape or a step with a part of the head portion 20a having a diameter smaller than the inner diameter of the bearing 16a can move the mounting screw inward, it is not necessary to project the boss portion outward.

( B ) In the above embodiment, the boss portion 17b projects when the handle 1 is mounted at the right position shown in FIG. 5, but it is also possible to project the boss portion 17b inward. For example, as shown in FIG. 6, by making the shape of the center side of the face gear 11 concave so that the bearing 16b can be stored, the bearing 16b can be brought inward, and the boss portion 17b can be made to protrude inward. Will be possible. If the reel body 2a is formed in such a shape, catching of the fishing line on both sides is reduced.

[0032]

According to the present invention, since at least one end of the handle shaft is arranged inside the bearing, when the handle is inserted from the other end, at least a part of the head portion of the mounting screw is also located above the bearing. It can be placed inside. For this reason,
The handle can be attached to the handle shaft without projecting outward the boss portion of the reel body for supporting the handle shaft.
