DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel body, and more particularly to a dual-bearing reel body to which a spool for spooling a spool is detachably mounted.

[0002]

2. Description of the Related Art A dual-bearing reel generally has a reel body mounted on a fishing rod and a spool for a bobbin rotatably mounted on the reel body. The reel body has a frame having a pair of left and right side plates and a plurality of connecting members for connecting the both side plates, and a pair of side covers covering both sides of the side plates. The one side cover is detachably attached to one side plate for attaching and detaching the spool, and the one side plate has a circular opening through which the spool can pass.

A dual-bearing reel of such a configuration is known in which a side cover on a handle mounting side is removed and a spool is removed. In such a dual-bearing reel, when the backlash causes dandruff on the spool, or when changing to a replacement spool wound with fishing line of different thickness, remove the side cover on the handle mounting side and remove the spool through the opening. From the reel body.

[0004]

In the above-mentioned conventional dual-bearing reel, the spool is connected via a clutch to a handle shaft for which rotation in the line payout direction is prohibited. For this reason, in a normal state in which the clutch is on, even if a relatively heavy device such as a lure is attached to the tip of the fishing line wound on the reel, the fishing line does not rotate in the line feeding direction. However, when you remove the side cover,
Since the clutch does not work, the spool is freely rotated. For this reason, the spool rotates in the line payout direction due to the weight of the tackle, and there is a possibility of causing a backlash in which the rotation speed of the spool is higher than the fishing line payout speed.

An object of the present invention is to prevent backlash from occurring even when the side cover is removed.

[0006]

According to a first aspect of the present invention, there is provided a reel body of a dual-bearing reel on which a spool for winding a bobbin is detachably mounted, and a frame, a first side cover, and a second side cover. And a spool detent means.
The frame includes a first side plate having an opening through which the spool can pass, a second side plate disposed at a distance from the first side plate, and a spool disposed between the first side plate and the first side plate, and a connection connecting the both side plates. And a member. The first side cover is a cover that is detachably attached to the first side plate, covers the outside of the first side plate, and has a handle attached thereto. The second side cover is the first
It is a cover provided on the side plate. The second cover is
It may be separate from or integral with the second side plate. The spool rotation preventing means is disposed at a release position where the spool is rotatable when the first side cover is mounted on the first side plate, and is disposed at a contact position where the spool rotates when the first side cover comes off. Means.

In the reel body of the dual bearing reel, when removing the spool, the first side cover is removed from the first side plate. Then, the rotation preventing means arranged around the opening is arranged at the contact position and comes into contact with the spool, and the rotation of the spool is regulated. Therefore, even if the first side cover is opened,
The spool is difficult to rotate in the line feeding direction. Therefore, backlash is less likely to occur when the first side cover is opened. When the first side cover is mounted on the first side plate after mounting the spool, the rotation preventing means is disposed at the release position, and the spool is in a rotatable state. However, since the spool is connected to the handle shaft via the clutch, it does not rotate in the line pay-out direction. here,
When the first side cover comes off, the spool is prevented from rotating by the spool detent means, so that even when the first side cover is removed, the spool is less likely to rotate in the line payout direction,
Backlash is less likely to occur.

According to a second aspect of the present invention, there is provided a dual-bearing reel body according to the first aspect, wherein the spool rotation preventing means is movably mounted on the first side plate around the opening between a contact position and a release position. A detent member, an urging member for urging the detent member toward the contact position, and pressing means for pressing the detent member toward the release position when the first side cover is attached. In this case, when the first side cover is detached, the detent member urged by the urging member is arranged at the contact position to detent the spool. And the first
When the side cover is mounted, the rotation preventing member is pressed by the pressing means and is located at the release position. Here, since the rotation preventing member is moved by the urging by the urging member and the pressing against the urging force by the pressing means, the structure of the spool detent means is simplified.

According to a third aspect of the present invention, there is provided the dual-bearing reel according to the second aspect, wherein the pressing means comprises:
A taper portion provided on the detent member, and a pressing portion provided on the first side cover and contacting the tapered portion when the first side cover is attached to the first side plate and pressing the detent member to the release position. Have. In this case, when the pressing portion is pressed against the tapered portion, the rotation preventing member is pressed to the release position by the action of the taper. When the pressing portion comes off from the tapered portion, the detent member is urged by the urging member and moves to the contact position. Here, the force in the mounting direction of the first side cover can be converted to the force in the releasing direction of the detent member by the tapered portion.

According to a fourth aspect of the present invention, there is provided a dual-bearing reel body according to the second or third aspect, wherein the rotation preventing member is mounted around the opening so as to be able to advance and retreat toward the rotation axis of the spool. . In this case, since the detent member is configured to be able to advance and retreat toward the rotation axis of the spool, the support structure of the detent member is simplified.

According to a fifth aspect of the present invention, there is provided a dual-bearing reel having the reel body according to the second or third aspect, wherein the rotation preventing member is mounted around the opening so as to be swingable in a direction of coming into contact with and separating from the spool. . In this case, since the detent member is swingably supported, the support structure of the detent member is simplified.

According to a sixth aspect of the present invention, there is provided the dual-bearing reel according to any one of the second to fifth aspects, wherein the spool comprises: a bobbin trunk on which a fishing line is wound;
A pair of large-diameter flange portions formed at both ends of the bobbin trunk, and the detent member contacts an outer peripheral surface of the flange portion. In this case, since the detent member comes into contact with the outer peripheral surface of the flange portion, the detent member does not hinder the attachment and detachment of the spool.

Contains.

The side plate 11 has an opening 11a through which the spool 15 can pass. When the side cover 14 is removed from the frame 5, the spool 15 can be removed through the opening 11a. Around the opening 11a, a side cover 14 is provided.
The spool 15 is provided with a spool rotation preventing mechanism 18 for preventing the spool 15 from rotating in the line payout direction when the spool 15 is removed from the frame 5.

As shown in FIGS. 3 and 4, the spool detent mechanism 18 is provided with a release position (two points in FIG. 4) separated from a contact position (solid line in FIG. 4) where the spool 15 comes into contact with the flange 15b of the spool 15 to prevent rotation. Chain line). The spool rotation preventing mechanism 18 is disposed in a storage recess 11b formed around the opening 11a. Spool detent mechanism 18
When the side cover 14 is mounted, the rotation preventing member 40 mounted on the housing concave portion 11b so as to be movable in the radial direction, the torsion coil spring 41 for urging the rotation preventing member 40 to the contact position side, And a pressing mechanism 42 for pressing the stop member 40 toward the release position.

The rotation preventing member 40 is formed by bending a metal plate at an acute angle, and a contact member 40a made of a synthetic resin elastic material is fixed to the tip of the bent portion. The contact member 40a is connected to the flange 1 of the spool 15.
The spool 15 is prevented from rotating by contacting the outer peripheral surface of the spool 5b.
The detent member 40 is fixed movably in the radial direction by a stepped bolt 43 screwed into the side plate 11. An oval long hole 40 b is formed in the stepped bolt penetrating portion of the rotation preventing member 40. The radial movement distance of the rotation preventing member 40 is restricted by the elongated hole 40b and the stepped bolt 43. The bent portion of the rotation preventing member 40 is a tapered surface 40c that is inclined obliquely. A pressing mechanism 42 is constituted by the tapered surface 40c and a pressing portion 19b provided on the mechanism mounting member 19 (described later). When the pressing portion 19b contacts the tapered surface 40c, the rotation preventing member 40 is pressed by the pressing portion 19b and moves from the contact position to the release position.

The rotation preventing member 40 is provided in the storage recess 11.
The b is mounted with a slight gap between both wall portions, and the detent member 40 is radially guided by the both wall portions.

The torsion coil spring 41 has one end locked to the rotation preventing member 40 and the other end locked to the side plate 11.
The torsion coil spring 41 presses the rotation preventing member 40 toward the radially inner contact position side by the urging force. The pressing mechanism 42 presses the rotation preventing member 40 radially outward against the pressing force.

A spool shaft 25 is fixed to the center of the spool 15, as shown in FIGS. The spool shaft 25 is provided with the bearing 2 on the side cover 13 and the side cover 14.
It is rotatably supported via 6, 26.

A mechanism mounting member 19 for mounting various mechanisms including a rotation transmitting mechanism 20 is detachably mounted on the side cover 14. The mechanism mounting member 19 has a boss portion 19a formed on the outer peripheral side of the spool shaft 25 so as to pass through a pinion gear 32 movably mounted in the axial direction. The spool shaft 25 is detachable from the boss portion 19a. Are rotatably supported also by the mechanism mounting member 19 by a bearing 27 mounted on the mechanism mounting member 19. Further, the mechanism mounting member 19 is provided with a pressing portion 19b (FIG. 4) for returning the detent member 40 that has swung to the release position to the contact position as described above. The pressing portion 19 b is formed so as to project toward the tapered surface 40 c of the rotation preventing member 40.

The rotation transmitting mechanism 20 includes a handle shaft 30 having one end to which the handle 2 is fixed, and a main gear 31 connected to the other end of the handle shaft 30 via a rotation control mechanism 22.
And a pinion gear 32 that meshes with the main gear 31. The handle shaft 30 is arranged parallel to the spool shaft 25, and the other end is rotatably supported by the mechanism mounting member 19. In such a configuration, when the clutch mechanism 21 is turned on, the rotational force from the handle 2 is directly transmitted to the spool 15.

The clutch mechanism 21 includes a pinion gear 32
And a clutch pin 36 disposed radially through the spool shaft 25. The clutch pin 36 can be engaged with an engagement groove 32a formed at one end of the pinion gear 32. When the clutch pin 36 is engaged with the engagement groove 32a, the clutch is turned on, and the pinion gear 32 is moved in the axial direction. If it moves and comes off, the clutch will be off. Pinion gear 3
2 is urged in the clutch-on direction (leftward in FIG. 1) by urging means (not shown).

[Attaching / Detaching Operation of Spool] In the dual-bearing reel configured as described above, when attaching / detaching the spool 15, the side cover 14 is removed. To remove the side cover 14, the two screws 17 for attachment and detachment may be loosened by hand. When the attachment / detachment screw 17 is loosened, the side cover 14 comes off the frame 5. At this time, the pinion gear 32 of the handle 2, the rotation transmission mechanism 20, and the clutch mechanism 21 is held by the mechanism mounting member 19 and detached together with the side cover 14. Then, only the spool 15 and the bearing 27 remain in the frame 5. Therefore, the spool 15 is in a freely rotatable state. However, when the side cover 14 comes off, the pressing portion 19b of the mechanism mounting member 19 separates from the tapered surface 40c of the rotation preventing member 40. As a result, the detent member 40
Is pressed by the torsion coil spring 41 and moves to the contact position, and the contact member 40a is
Press the outer peripheral surface of b. For this reason, the spool 15 is braked, and the possibility that the spool rotates due to the weight of the tackle is reduced even if the tackle is attached to the fishing line. In this state, even if the opening 11a is held downward while holding the frame, since the rotation preventing member 40 is arranged at the contact position and is in contact with the spool 15, the spool 15 is less likely to fall off. And
When the spool 15 is pushed rightward in FIG. 1, the spool 15 contacts the contact member 40 a of the
5 can be taken out.

When the spool 15 is mounted, the spool 15 is inserted through the opening 11a. At this time, even if the contact member 40a of the rotation preventing member 40 is located inside the opening, the tapered surface 40c is pressed by the flange portion 15b of the spool 15 and is slightly retracted. In this state, the side cover 14 is mounted on the frame 5. Then, the mechanism mounting member 1
9 is the tapered surface 40c of the rotation preventing member 40.
And presses the detent member 40 toward the release position.
Then, the contact member 40a is connected to the flange 1 of the spool 15.
The spool 15 is separated from the outer peripheral surface of the spool 5b, and the spool 15 becomes freely rotatable. However, when the side cover 14 is attached, the clutch mechanism 21 enters the clutch-on state, and the spool 1
Since the rotation of the spool 5 in the line feeding direction is prohibited, the spool 15 does not rotate in the line feeding direction.

Here, since the rotation preventing mechanism 18 is provided in the opening 11a of the side plate 11, when the side cover 14 comes off, the spool 15 is prevented from rotating. For this reason, the side cover 1
Even if 4 is removed, the spool 15 will not easily rotate in the line payout direction, and backlash will not easily occur.

[Other Embodiments] (a) In the above embodiment, the detent member 40 is opened
1a is mounted so as to be movable in the radial direction around the opening 11a.
May be mounted so as to be freely swingable.

(B) In the above embodiment, a round dual-bearing reel has been described as an example. However, the present invention can be applied to a low-profile type dual-bearing reel, for example. (C) In the above embodiment, the spool rotation preventing mechanism 18 is provided at one location around the opening 11a, but may be provided at two or more locations facing the periphery of the opening 11a.

[0030]

According to the present invention, when the first side cover is removed, the spool is prevented from rotating by the spool rotation preventing means. Therefore, even when the first side cover is removed, it is difficult for the spool to rotate in the line feeding direction. And backlash is less likely to occur.
