Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a rotor drive mechanism, and more particularly to a spinning reel rotor drive mechanism for transmitting rotation from a handle to a rotor rotatably mounted on a reel body of a spinning reel.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body having a handle, a spool mounted on the reel body so as to be movable back and forth, and a fishing line wound around the outer periphery, and a spool rotatably supported by the reel body to wind the fishing line around the spool. And a rotor drive mechanism for transmitting the rotation of the handle to the rotor.

[0003] 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 on the reel body by bearings, and protrude outward from the bearings. The bearing for supporting the handle shaft is mounted inside a pair of bosses formed to protrude left and right on the reel body. 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 either end of the handle shaft. The handle is attached to the handle shaft by screwing an attachment screw attached from a shaft end opposite to the insertion end to the handle. 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 a spinning reel having a rotor drive mechanism configured as described above, the boss portion of the reel body opposite to the side on which the handle is mounted is closed by, for example, a cap screwed into the boss portion.

[0005]

In the conventional rotor drive mechanism, 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. For this reason, when the handle is mounted on the handle shaft, it is necessary to project the boss portion for supporting the handle shaft outward to cover the head of the mounting screw. When the boss protrudes outward in this manner, the fishing line may be hooked on the boss when the fishing line is slackened. Also, if the cap is put on the protruding boss, foreign matter enters between the boss and the cap, and it is difficult to remove the foreign matter.

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

[0007]

A spinning reel rotor drive mechanism according to the first aspect of the present invention is a mechanism for transmitting rotation from a handle to a rotor rotatably mounted on a reel body of the spinning reel, the handle being a handle. A shaft, a face gear, a pinion gear, and a mounting screw are provided. The handle shaft is rotatably supported at both ends via a bearing on the reel body, and at least one of its ends is disposed inside the outer surface of the bearing, and the tip of the handle rotates inward from any end. It has a through-hole at the center that can be inserted impossibly. The face gear is provided non-rotatably on the handle shaft. The pinion gear meshes with the face gear, and the rotor is non-rotatably mounted. 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 smaller diameter than the head portion. This is a screw for attaching.

In this rotor drive mechanism, 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 mounting screw to the handle from the other end. At this time, 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 of the mounting screw can be arranged inside the bearing. Therefore, the handle can be attached to the handle shaft without projecting the boss of the reel body for supporting the handle shaft outward.

A spinning reel rotor driving mechanism according to a second aspect of the present invention is the mechanism according to the first aspect, wherein the head has a smaller diameter than the inner diameter of the bearing. In this case, since the head of the mounting screw is smaller in diameter than the bearing, the entire head can be arranged inside the bearing. For this reason, the protrusion of the boss can be further suppressed. A spinning reel rotor drive mechanism according to a third aspect of the invention is the mechanism according to the first or second aspect, wherein the face gear is formed integrally with the handle shaft. In this case, since the handle shaft and the face gear are integrated, their manufacture and assembly are facilitated.

[Reel Operation and Operation] At the time of fishing, it is sometimes necessary to change the mounting position of the handle 1. For example, at the time of lure fishing or throw fishing, the handle 1 is often mounted on 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, the handle 1 is often mounted on the right side as shown in FIGS. 1, 3 and 5 in order to operate the handle 1 with the dominant arm. The left and right mounting positions of the handle 1 also differ depending on personal preference.

When the mounting position of the handle 1 is changed from the left position shown in FIG. 4 to the right position shown in FIG. 5, first, two screws 19a are removed and the shaft cover 19 is removed from the boss 17a. Subsequently, the handle 1 is pulled out from the left end of the handle shaft 10 in FIG. After the handle 1 is pulled out, the two screws 19a are removed, and the perforated cover 19b is also removed from the boss 17b. Then, the removed perforated cover 19b is attached to the boss 17a by two screws 19a.
Attach by Subsequently, the shaft portion 1c of the handle 1 pulled out from the right end of FIG.
b through the through hole 10a. Then, the attachment screw 20 is screwed from the boss 17b on the left side of FIG. Finally, the shaft cover 19 is mounted on the boss 17a with two screws 19a to cover the boss 17a. Thus, the handle 1 is 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, the boss portion 17a does not protrude outward, so that the reel body 2a has a smooth surface and the fishing line is not easily caught. Also, new designs can be obtained. At the time of casting, the bail arm 44 is turned over to the line releasing posture with the handle 1 attached to the left position shown in FIG. Thereby, the first bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. In this state, when the handle 1 is rotated in the yarn winding direction with, for example, the left hand, the rotor drive mechanism 5
As a result, the rotor 3 rotates in the yarn winding direction, and the bail arm 4
4 is returned to the line guiding posture by the bail reversing mechanism 46, and the fishing line is wound around the spool 4.

[Other Embodiments] (b) The head portion 20a of the mounting screw 20 does not need to have a small diameter as a whole, but may have a portion smaller than the inside diameter of the bearing 16a. That is, even if a part of the head 20a has a tapered or stepped mounting screw whose diameter is smaller than the inner diameter of the bearing 16a, the mounting screw can be moved inward, so that it is not necessary to project the boss outward.

(A) In the above embodiment, the boss 17b protrudes when the handle 1 is mounted at the right position shown in FIG. 5, but the boss 17b may protrude inward. For example, as shown in FIG. 6, the shape of the center side of the face gear 11 is made concave so that the bearing 16b can be housed, so that the bearing 16b can be moved inward, and the boss portion 17b projects inward. Becomes possible. If the reel body 2a is formed in such a shape, the catch of the fishing line on both sides is reduced.

[0026]

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