Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-bearing fishing reel for preventing a line entanglement phenomenon (backlash phenomenon) when releasing a fishing line (during casting).

[0002]

2. Description of the Related Art Conventionally, double-bearing reels for fishing have
In order to prevent the spool from rotating excessively when the fishing line is released, various backlash prevention mechanisms are provided.
As a general one, a friction brake device using centrifugal force and a magnetic brake device using magnetic force are known.

In the above-described friction brake device, since the friction braking force changes abruptly with respect to the rotation speed of the spool due to the characteristic that the friction braking force changes secondarily, the friction braking force in the initial casting increases sharply. The flight distance of the device decreases,
There is a problem that the fishing line is excessively released due to a sharp decrease in the friction braking force at the end of casting, and the backlash phenomenon is likely to occur. Further, the magnetic brake device has a characteristic that a braking force is generated substantially in proportion to the rotation speed of the spool,
Although the backlash phenomenon is less likely to occur than the friction brake, when the spool rotation speed at the end of casting decreases, the flight distance of the device can not be extended,
There are problems such as poor short casting performance.

To solve these problems, Japanese Unexamined Patent Publication No. Hei 10-262519 discloses a magnetic brake system in which the rotation of a spool is reduced in order to prevent a decrease in the flight distance of a device at the beginning and end of casting. There is disclosed a technique that changes a distance between a magnet and a conductor according to a speed and adjusts a closest approach distance between the magnet and the conductor.

According to this magnetic brake device, the spool rotation braking force generated by the magnetic braking action at the beginning and end of the casting is suppressed, so that the flight distance of the device can be improved and the backlash phenomenon can be prevented. Will be able to

[0006]

However, the technique disclosed in the above-mentioned publication has a structure in which the spool rotation braking force is suppressed at the beginning and end of the casting, so that the flying distance of the device is difficult to be obtained (for example, in a head wind). When the full cast is performed under strong conditions, the fishing line is excessively released and the backlash phenomenon is likely to occur. Also, for beginners who do not value the flight distance of the device, the backlash phenomenon is likely to occur unless some spool rotation braking force is provided at the beginning and end of the casting because the summing operation is inexperienced. Would.

SUMMARY OF THE INVENTION The present invention has been made based on the above-mentioned problem, and has a backlash prevention mechanism capable of performing an optimum spool rotation speed control setting in accordance with the conditions of a fishing place or a user's request. It is an object of the present invention to provide a dual-bearing type reel.

[0008]

In order to achieve the above object, a dual-bearing fishing reel according to the present invention has a spool rotatably supported between side plates of a reel body, and the spool is wound around a fishing line. A clutch mechanism selectively switchable between a take-off state and a fishing line release state, a conductor provided on one of the spool and the reel body, and a conductor provided on the other of the spool and the reel body; A magnet that brakes the rotation of the spool by applying a magnetic force to
Spool rotational speed control means which is movable in the axial direction of the spool in accordance with the increase or decrease in the rotational speed of the spool, and controls the rotational speed of the spool by increasing or decreasing the magnetic force acting on the conductor by the magnet. Further, a switching mechanism is provided for selectively switching the rotation speed control means between a movable state where the spool can be moved in the axial direction and a non-movable state.

According to the above configuration, by operating the switching mechanism in response to a fishing place or a user's request, a state where no braking force acts on the spool at the beginning and end of the casting can be obtained.
The state is always switched to a state in which a braking force acts on the spool.

[0010]

It can be switched to a rotation state (clutch OFF state). The return from the clutch OFF state to the clutch ON state can be performed by operating the handle 1 in addition to operating the clutch operation member.

By rotating the drag operation member 27 attached to the handle shaft 10, the drive gear 21 is pressed with a predetermined pressing force, and this pressing force acts on the ratchet 28 which rotates integrally with the handle shaft 10, A predetermined drag force is generated between the handle shaft 10 and the drive gear 21.

A level wind device having a fishing line guide portion 30 and a reciprocating mechanism 31 is provided between the left and right frames 2a and 2b. By rotating the handle 10a, a fishing line guide is provided on the spool 6a. The fishing line is wound evenly through the portion 30. In the level wind device according to the present embodiment, the fishing line guide portion 30 and the reciprocating mechanism 31 are disposed separately before and after the spool 6a, but these may be disposed in front of the spool 6a. .

One end of a spool 6a (spool shaft 6) of the fishing dual-bearing type reel configured as described above is provided with:
A backlash prevention mechanism 40 is provided to prevent the spool 6a from rotating excessively when the fishing line is fed.

The backlash prevention mechanism according to the present embodiment is provided on an annular conductor 41 that rotates integrally with the spool 6a (spool shaft 6) and the reel body (right frame 2b), and the annular conductor 41 is inserted. In this case, a magnet 42 acts to apply a magnetic force to the rotation of the spool 6a, and the magnet 42 is movable along the spool axis in accordance with an increase or decrease in the rotation speed of the spool 6a. And a spool rotation speed control means 45 for controlling the rotation speed of the spool 6a by increasing or decreasing the magnetic force to be applied. The rotation speed control means 45 can be moved in the axial direction of the spool by a switching mechanism 60 described later (a state in which the magnetic force acting on the conductor 41 can be increased or decreased in accordance with an increase or decrease in the rotation speed of the spool 6a). And a state in which the conductor 41 cannot be moved (a state in which a magnetic force is constantly applied to the conductor 41).

Hereinafter, the above-described backlash prevention mechanism 4 will be described.
0 will be described. FIGS. 2 to 4 are views showing a backlash prevention mechanism provided in the double-bearing fishing reel shown in FIG.

The spool rotation speed control means 45 has a support 46 which rotates integrally with the spool shaft 6 and is movable in the axial direction. The support body 46 is formed in a collar shape, and the biasing spring 47 is engaged with the bottom of the recess formed in the end face thereof and is constantly biased toward the spool. The support 46 is provided with a support portion 46a projecting in a radial direction at a predetermined interval, and the annular conductor 41 is fixed to a tip side of the support portion. A centrifugal moving member 48 is supported by each support portion 46a so as to be movable in the radial direction.
When the (support member 46) rotates together with the spool 6a, it moves radially outward due to the centrifugal force.

On the back side of the fishing line winding surface of the spool 6a, a taper 6 whose diameter gradually increases toward the right frame 2b is provided.
b is formed, and when the centrifugal moving member 48 moves radially outward, the outer surface thereof comes into surface contact with the taper 6b. That is, the spool shaft 6 (the spool 6
When the rotation speed of a) increases, the centrifugal moving member 48 moves in the radial direction according to the centrifugal force, and moves toward the right frame 2b along the taper 6b.

The magnet 42 is provided with a pair of annular magnetic bodies 42a and 42b at predetermined intervals so that the annular conductor 41 can be inserted and removed, and each magnetic body has an S pole and an N pole. Are alternately arranged. The outer magnetic body 42a is rotated by a predetermined range by rotating a dial 42c (see FIG. 1) exposed from the right side plate 3b, and an annular conductive member inserted within a predetermined interval. It is configured such that the braking force acting on the body 41 can be adjusted.

The conductor 41 is positioned so as not to be inserted between the magnetic bodies 42a and 42b when the spool shaft 6 is not rotating in the fishing line releasing direction, as shown in FIG.

According to the spool rotational speed control means 45 having the above-described structure, at the time of the initial casting (in a state where the rotational speed of the spool 6a is not sufficiently increased), the conductor 41 is formed of a pair of annular magnetic members 42a. , 42b, the braking force does not act on the spool 6a, and the flight distance of the device does not decrease. When the spool 6a rotates at a high speed, the centrifugal moving member 48 moves radially outward according to the rotation speed, and the right frame 2 moves along the taper 6b.
The support 46 moves to the side b.
7 to the right frame 2b side. As a result, as shown in FIG. 3, the conductor 41 enters into the space between the pair of annular magnetic bodies 42a and 42b, and applies a braking force to the spool 6a that rotates at a high speed by the magnetic action. As a result, excessive rotation of the spool 6a is suppressed, and backlash is effectively prevented. At the end of casting, the support 46 moves to the spool side by the urging force of the urging spring 47,
1 is out of the space between the pair of annular magnetic bodies 42a and 42b, the braking force acting on the spool 6a is weakened, and the flight distance of the device can be extended immediately before landing (the flight distance of the device). It does not decrease).

As described above, by setting the rotation speed control means 45 in a state in which the spool can be moved in the axial direction, it is possible to improve the flight distance of the device.

Next, a description will be given of a switching mechanism 60 for selectively switching the rotation speed control means 45 between a state in which it is movable in the axial direction of the spool as described above and a state in which it is not movable.

The switching mechanism 60 in the backlash prevention mechanism shown in FIGS. 2 to 4 includes a screw part 61 formed on the outer peripheral surface of the end of the support 46 on the right frame 2b side, and a screw part 61 formed on the screw part 61. It is constituted by a cylindrical regulating member 62 (see FIG. 4) having an engaging portion 62a. According to this configuration, the right side plate is removed from the reel body, and the spool 6 is removed.
a, the restricting member 62 is screwed into the screw portion 61 from the right side of the spool shaft 6, and the locking portion 62a is locked in a circumferential groove 6d formed in the spool shaft 6, thereby supporting the support member. The movement of 46 in the axial direction is restricted. In this restricted position, as shown in FIG.
Is always located within the interval between the pair of annular magnetic bodies 42a and 42b.

As described above, the rotational speed control means 45 is set in a state in which it cannot be moved in the axial direction, that is, in a state where the conductor 41 is always positioned within the interval between the pair of annular magnetic bodies 42a and 42b. The spool 6a is in a state where a braking force is constantly applied when the fishing line is released. That is, if the full cast is performed in a situation where it is difficult to obtain the flying distance of the device, such as a strong head wind, the fishing line is excessively released and a backlash phenomenon is likely to occur, but as described above, the rotation speed control means 45 is moved in the axial direction. By switching to the immovable state,
Excessive rotation of the spool at the beginning of casting is suppressed, and the backlash phenomenon can be effectively prevented. In addition, when a beginner who does not attach importance to the flight distance of the device is used, a braking force can be applied to the spool at the beginning and end of the casting, so that light and stable casting can be performed.

As described above, according to the fishing dual-bearing type reel having the backlash prevention mechanism having the above-described structure,
Optimum spool rotation speed control settings can be made in accordance with the conditions of the fishing area, the requirements of the user, and the like.

FIGS. 5 to 7 are views showing a second embodiment of a double-bearing fishing reel, showing a backlash preventing mechanism incorporated in such a dual-bearing fishing reel. . In the following description of the backlash prevention mechanism, portions different from the backlash prevention mechanism shown in FIGS. 2 to 4 will be described, and the same components will be denoted by the same reference numerals. Is omitted.

The rotational speed control means 45 'of the backlash prevention mechanism of this embodiment has a support 56 which rotates integrally with the spool shaft 6 and is movable in the axial direction. The support 56 is formed in a collar shape, and is constantly urged toward the spool by an urging spring 47.
The support 56 is provided with a support portion 56a that protrudes in the radial direction at a predetermined interval, and the annular conductor 41 is fixed to the distal end side of the support portion. In addition, each support 56
a, the centrifugal moving member 4 is provided so as to be movable in the radial direction.
8 is supported, and when the spool shaft 6 (support 56) rotates together with the spool 6a, the centrifugal force causes the spool shaft 6 to move radially outward.

A tapered taper 41a is formed on the outer periphery of the leading end of the conductor 41 so as to widen the adjustment range of the braking force. In other words, by forming such a taper 41a, it is possible to effectively apply a braking force particularly at the time of short casting (pitching) of a low-speed rotation of the spool.

Next, the configuration of a switching mechanism 60 'for selectively switching between a state in which the rotational speed control means 45' is movable in the axial direction of the spool and a state in which the rotational speed control means 45 'is not movable will be described.

The switching mechanism 60 'includes a long groove 56b formed along the axial direction from the spool-side end surface of the support 56 toward the right frame 2b, and a short groove 56c formed adjacent to the long groove 56b. Each groove is provided with a pin 6g selectively formed so as to protrude from the spool shaft 6.

Specifically, when the pin 6g is engaged with the long groove 56b, as shown in FIGS.
The (conductor 41) is movable in the axial direction against the urging force of the urging spring 47 according to the increase or decrease of the rotation speed of the spool 6a. Also, the right side plate is removed from the reel body, the spool 6a is taken out, the support 56 is rotated while moving against the urging force of the urging spring 47, and the pin 6g is engaged with the short groove 56c to be supported. The movement of the body 56 in the axial direction is restricted. And in this regulation position, as shown in FIG.
The conductor 41 is always a pair of annular magnetic bodies 42a, 42b.
Is located within the interval of.

As described above, the switching mechanism 6 according to the present embodiment is
According to 0 ′, the moving state of the rotation speed control means 45 ′,
Switching to the non-movable state only requires rotating the support member 56, so that operability is improved.

FIGS. 8 to 12 are views showing a third embodiment of a double-bearing fishing reel, showing a backlash preventing mechanism incorporated in such a dual-bearing fishing reel. .

The rotation speed control means 75 of the backlash prevention mechanism of this embodiment includes a support member 76 fixed to the spool shaft 6. The support member 76 has a cylindrical portion 76a fixed to the spool shaft 6 with a locking portion.
And a holding portion 76b that holds a centrifugal moving member 78 that is movable in the radial direction and the spool axial direction and is in surface contact with the taper 6b of the spool. An engaging portion 76c extending parallel to the taper 6b of the spool is formed at the upper end of the holding portion 76b, and on the back side of the engaging portion 76b,
A regulating claw 78a formed inside the centrifugal moving member 78 is engaged (see FIG. 9).

The support member 76 holds a conductor 81 so as to be movable in the axial direction along the cylindrical portion 76a. In this case, the conductor 81 is sandwiched between the cylindrical portion 76a and the outer peripheral surface of the spool shaft 6, and slides on the spool shaft 6 and is biased toward the spool by the biasing spring 47. Are formed integrally. The conductor 81 is engaged with the centrifugal moving member 78. When the centrifugal moving member 78 moves in the axial direction, the conductor 8
1 is also movable in the axial direction (within the interval between the annular magnetic bodies 42a and 42b) against the urging force of the urging spring 47.

A plurality of such support members 76 and centrifugal moving members 78 are provided on the spool shaft 6 at predetermined intervals (for example, at 180 ° intervals).

Next, the configuration of a switching mechanism 90 for selectively switching between a state in which the rotation speed control means 75 is movable in the axial direction of the spool and a state in which it is not movable will be described.

The switching mechanism 90 includes an engaging portion 76c formed on the support member 76 and a regulating claw 78a formed inside the centrifugal moving member 78.

Specifically, in the movable state, as shown in FIGS. 8 and 9, the regulating claw 78a is located on the back side of the engaging portion 76c in the fixed state, and when the spool 6a rotates. The centrifugal moving member 78 can move in the radial direction, and can move in the axial direction along the taper 6b of the spool and the engaging portion 76c parallel to the taper 6b as shown by a solid line to a dotted line in FIG. ing. Then, by removing the right side plate from the reel body, taking out the spool 6a, moving the conductor 81 in the axial direction against the urging force of the urging spring 47, and moving the centrifugal moving member 78 radially outward. Thus, the movement of the centrifugal moving member 78 and the conductor 81 in the axial direction is restricted. That is, the centrifugal moving member 78 is moved radially outward such that the regulating claw 78a crosses the engaging portion 76c against the elastic force, and the regulating claw 78a is applied to the upper side of the engaging portion 76c (see FIG. 11), the centrifugal moving member 78
The conductor 81, which is sandwiched between the taper 6 b of the spool and the engaging portion 76 c parallel to the spool and moves in the axial direction integrally with the centrifugal moving member 78 due to frictional resistance therebetween, moves in the axial direction. Is regulated (see FIG. 10).

Then, as shown by the arrow in FIG. 12, by moving the centrifugal moving member 78 inward in the radial direction, the restricting claw 78a climbs over the engaging portion 76c against the elastic force, and as shown in FIGS. As shown in FIG.
Becomes movable in the axial direction.

As described above, in the present embodiment,
The operation of switching the rotational speed control means 75 between the state in which the spool can be moved in the axial direction and the state in which the rotation speed cannot be performed can be performed by operating the centrifugal moving member 78 in the radial direction, so that the operability at the time of switching is improved. I do.

Although the embodiment of the present invention has been described above, the present invention provides a rotation speed control means for moving a conductor in the axial direction of the spool in accordance with the rotation speed of the spool. The configuration of the switching mechanism can be variously modified as long as it can be switched so as to be maintained at the braking force application state. FIG.
