Japanese Patent No. 3305926

In the fishing reel of Patent Document 1 described above, the end surface of the screw shaft is pressed by the rotation of the adjusting knob via the pressing plate. For this reason, there is a limitation in increasing the diameter of the screw shaft end surface that is the pressing surface in consideration of size reduction, weight reduction, maintenance, and the like. Therefore, the fishing reel of Patent Document 1 has a problem that efficient and sufficient spool braking cannot be performed with respect to the rotating operation of the adjusting knob.

An object of the present invention is to provide a fishing reel that can efficiently obtain a high braking force with respect to the rotating operation of the adjusting knob.

To achieve the above object, a fishing reel of the present invention includes a spool rotatably supported by a reel body and around which a fishing line is wound, and a spool braking device for braking the spool. .. The spool braking device includes a gear that rotates in association with the rotation of the spool when the fishing line is paid out, and a braking member that is provided laterally to the side surface of the gear and that abuts the side surface of the gear.

In this fishing reel, since the side surface of the gear that rotates in association with the rotation of the spool when the fishing line is paid out is used as a braking surface for abutting the braking member, a wide effective area for braking can be set. .. Therefore, a high braking force can be efficiently generated even with a small pressing force.
Further, the spool braking device has a simple structure in which the braking member is brought into contact with the side surface of the gear, and it is not necessary to fix the braking member acting as a braking surface by a separate component. In addition, the cost of parts can be reduced.

Further, when a level wind device that has a screw shaft that rotates in association with the rotation of the handle and that uniformly guides the fishing line to the spool is provided, the gear is provided at the end of the screw shaft. It is preferably provided. With this configuration, the braking member can be arranged at the end of the screw shaft with space efficiency. Further, the screw shaft is usually located at the upper part or the front part of the reel body, and the braking member is arranged on the side thereof. Therefore, the knob member for operating the braking member is unlikely to interfere with the fingers holding the reel body, and the fishing operability is excellent.

Further, it is preferable that the gear includes an annular protrusion that comes into contact with the braking member. With this configuration, it is possible to set a large effective area for braking, and it is possible to generate a high braking force even with a small pressing force. In addition, a space (annular recess) for fixing the gear to the screw shaft can be secured inside the annular projection in the radial direction. This facilitates the work of attaching/detaching the gear to/from the end of the screw shaft, and contributes to downsizing and weight reduction of parts.

According to the present invention, it is possible to obtain a fishing reel that can efficiently obtain a high braking force with respect to the rotating operation of the adjusting knob.

Further, between the left and right frames 2a and 2b, an electric motor, a speed reduction mechanism, etc., which are not shown, are additionally provided. A handle shaft (not shown) is rotatably supported by the left frame 2a and the left side plate 3a. A clutch mechanism 20 is provided on the left side of the spool 5. As is well known, the clutch mechanism 20 switches the spool 5 between a fishing line winding state and a fishing line releasing state by operating a rear switching lever 21.
In the present embodiment, the spool braking device 30 is provided on the left side of the level wind mechanism 10. Details of the spool braking device 30 will be described later.

The left and right frames 2a and 2b are portions that form the skeleton of the reel body 1. The left and right frames 2a and 2b are integrated via a plurality of columns (not shown). A front side plate 8m is attached to the front side of the left and right frames 2a and 2b via a front frame (not shown).
The left and right frames 2a and 2b and the front frame are made of, for example, a metal material such as an aluminum alloy or a magnesium alloy.

The spool 5 is rotationally driven in the fishing line winding direction through a winding operation of a manual handle (not shown), a power transmission mechanism that transmits the rotational driving force of the electric motor, and the like. The power transmission mechanism has a function of reducing the rotational driving force of the drive motor and transmitting it to the spool 5 side (a reduction mechanism), a function of not rotating the manual handle even if the drive motor is rotationally driven, and a reverse rotation of the manual handle It has a function to do. In FIG. 1, reference numeral O2 is the central axis of the spool 5.

The level wind mechanism 10 is a device for making the fishing line wound around the spool 5 uniform. As is well known, the level wind mechanism 10 includes a screw shaft 11 rotatably mounted between the left and right frames 2a and 2b in front of the spool 5, a guide cylinder 12 covering the screw shaft 11, and an outer peripheral surface of the guide cylinder 12. And a fishing line guide body 13 that slides on.

As shown in FIG. 2, the left end 11 a of the screw shaft 11 projects laterally of the left frame 2 a via the support member 14. The left end portion 11a has a flat surface portion 11c formed on the outer surface and has a non-circular cross section (not shown). A gear 31 that constitutes the spool braking device 30 is fitted to the left end portion 11a via the flat surface portion 11c so as not to rotate. A peripheral groove 11b is formed at the tip of the left end portion 11a, and a retainer 16 for retaining the gear 31 in place is retained on the peripheral groove 11b.

The spool braking device 30 includes a gear 31 and a braking mechanism 32.
The gear 31 is fixed to the screw shaft 11 and rotates integrally with the screw shaft 11. As shown in FIG. 1, the gear 31 is supplied with a fishing line by a gear transmission mechanism such as a gear 5c that rotates integrally with the spool 5, a first interlocking gear 5b and a second interlocking gear 5a (see FIG. 1). The rotational driving force of the spool 5 that rotates from time to time is transmitted. That is, the gear 31 (integrally rotated with the screw shaft 11) is configured to rotate by the rotational driving force of the spool 5 when the fishing line is delivered in the fishing line discharging state by the clutch mechanism 20.

On both right and left side surfaces of the gear 31, annular projections 311 and 312 projecting in the axial direction are integrally formed. The outer surfaces in the axial direction of both annular protrusions 311 and 312 are formed flat.
The left annular protrusion 311 faces the friction lining member 332 of the left braking mechanism 32. The right annular protrusion 312 is in contact with the washer 15 provided between the right annular protrusion 312 and the left side surface of the support member 14.
An annular recess 311a is formed radially inside the left annular protrusion 311. The retainer 16 is housed in the recess 311a. That is, the retainer 16 is fitted onto the circumferential groove 11b of the left end portion 11a of the screw shaft 11 by utilizing the space formed in the recess 311a. By forming the recessed portion 311a, the work of attaching and detaching the gear 31 by the retainer 16 can be easily performed.
The gear 31 does not need to be detachably fitted to the screw shaft 11 in a detachable manner, but is integrated (integrally formed with the screw shaft 11 or fixed by caulking) and mounted from the frame 2a side, and the end on the frame 2b side. The part may be retained by a retainer so as to be restricted in the axial direction.

The braking mechanism 32 includes a knob member 321, a guide tube portion 323, a pressing plate 329, a spring washer 330, a slider 331, and a friction lining member 332. The braking mechanism 32 is arranged coaxially with the central axis O1 (see FIG. 1) of the screw shaft 11. The braking mechanism 32 is housed in a space formed inside the concave peripheral wall 3a1 provided on the left side plate 3a in the radial direction. A plate-shaped mounting wall 3a2 is provided on the radially inner side of the concave peripheral wall 3a1 via a support member (not shown).

The knob member 321 has a bottomed tubular shape, and has a peripheral wall portion 321a and a bottom portion 321b that is continuous with the left end portion of the peripheral wall portion 321a. The opening side of the peripheral wall portion 321a extends inside the concave peripheral wall 3a1 through a gap formed between the concave peripheral wall 3a1 and the mounting wall 3a2. A shaft portion 325 is integrally formed at the center of the right surface of the bottom portion 321b. The shaft portion 325 extends through the mounting wall 3a2 toward the gear 31. A male screw is formed on the outer peripheral surface of the shaft portion 325.

Further, a protrusion 326 is formed at the tip (right end) of the shaft 325. A pressing plate 329 is fixed to the tip end surface (right end surface) of the protrusion 326. The pressing plate 329 is moved to the right by rotating the knob member 321 in the tightening direction. Further, the pressing plate 329 is moved to the left side by rotating the knob member 321 in the direction of loosening it. A groove 327 is formed at the boundary between the shaft 325 and the protrusion 326. A disc spring-shaped stopper 328 is externally fitted in the groove 327. When the knob member 321 is loosened, the stopper 328 contacts the right side surface of the left portion 322, which will be described later, of the guide cylinder portion 323 and the right side surface of the female screw 322a continuous with the left side portion 322, and the shaft portion 325 is further leftward. Regulate the movement of people.

The guide cylinder portion 323 has a substantially cylindrical shape. The left portion 322 of the guide tube portion 323 is fixed to the right side surface of the mounting wall 3a2. A female screw 322 a is attached to the inside of the left portion 322 of the guide tube portion 323. The male screw of the knob member 321 is screwed into the female screw 322a. The knob member 321 is supported by the guide cylinder 323 by screwing the male screw of the knob member 321 into the female screw 322a.

A pair of slits 324 is formed in the front-rear direction in the area on the right side of the center portion of the guide tube portion 323 in the left-right direction. The pair of slits 324 are provided to face each other in the radial direction.

The spring washer 330 is provided between the pressing plate 329 and the slider 331. By tightening the knob member 321, the spring washer 330 is pushed by the pressing plate 329 and biases the slider 331 toward the gear 31 side (right side).

The slider 331 is engaged with a pair of slits 324 provided on the outer circumference of the guide cylinder 323 to face each other in the radial direction, and is prevented from rotating in the axial direction. The right side portion of the spring washer 330 is in contact with the left inner surface of the slider 331.

The friction lining member 332 functions as a braking member. The friction lining member 332 is formed in a substantially circular shape (not shown). The friction lining member 332 is fixed to the right side surface of the slider 331. The friction lining member 332 faces the annular protrusion 311 of the gear 31. The friction lining member 332 comes into contact with the side surface of the annular protrusion 311 of the gear 31 by the rotation of the knob member 321 in the tightening direction.

Next, the operation of the spool braking device 30 in the fishing reel 100 of this embodiment will be described.
As shown in FIG. 2, tighten the knob member 321 from the state in which the friction lining member 332 is not in contact with the side surface of the annular protrusion 311 of the gear 31, that is, the state in which the braking force does not act on the gear 31. When rotated in the direction, the knob member 321 moves to the right.

After that, when the knob member 321 is rotated in the tightening direction, the friction lining member 332 comes into contact with the side surface of the annular protrusion 311 of the gear 31, as shown in FIG. This contact causes a slight braking force to be generated in the rotation of the gear 31. From this state, when the knob member 321 is further rotated in the tightening direction, the friction lining member 332 urged by the spring washer 330 presses the gear 31, and the braking force on the gear 31 becomes stronger. As a result, the rotation of the spool 5 is braked via the gear transmission mechanism such as the gear 31, the second interlocking gear 5a, the first interlocking gear 5b, and the gear 5c.

After that, when the knob member 321 is continuously tightened, the spring washer 330 is compressed between the pressing plate 329 and the slider 331 to be substantially flat as shown in FIG. In this state, the urging force of the spring washer 330 becomes maximum, and the maximum braking force acts on the gear 31, that is, the spool 5.

In the fishing reel 100 of the present embodiment described above, the side surface of the gear 31 that rotates in association with the rotation of the spool 5 when the fishing line is fed is used as the surface with which the friction lining member 332 abuts. That is, the friction lining member 332 is configured to contact the side surface of the gear 31 in the circumferential direction. Therefore, the effective area for braking can be set wide. Therefore, a high braking force can be efficiently generated even with a small pressing force due to the rotating operation of the knob member 321.

Further, the spool braking device 30 has a simple structure in which the friction lining member 332 is brought into contact with the annular projection 311 which is the side surface of the gear 31, and it is not necessary to fix the braking member by another member. Therefore, the cost of parts can be reduced, and the size and weight can be reduced.

Further, since the braking member is not fixed by press fitting, it is possible to disassemble the area around the friction lining member 332. Therefore, the maintainability is excellent and the cost of parts is reduced.

Further, since the gear 31 is attached to the end portion of the screw shaft 11, the friction lining member 332 (braking member) and the like can be efficiently arranged in the end portion of the screw shaft 11 in terms of space. Further, the screw shaft 11 is usually located at an upper portion or a front portion of the reel body 1, and a friction lining member 332 (braking member) or the like is arranged on the side thereof. Therefore, the knob member 321 does not easily interfere with the fingers holding the reel unit 1 and is excellent in fishing operability.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and can be variously modified.
For example, in the above-described embodiment, the gear 31 is provided with the annular protrusion 311 and the friction lining member 332 is brought into contact with the annular protrusion 311. However, the present invention is not limited to this. For example, as shown in FIG. 5, an annular friction lining member 332A may be used, and the facing surface (left side surface) of the facing gear 31A may be formed flat so that the friction lining member 332A abuts. .. In this case as well, the same operational effects as those of the above-described embodiment can be obtained. Further, the friction lining member 332A and the gear 31A can be further reduced in size and weight. Therefore, the cost can be reduced.

Further, the friction lining member 332 (332A) does not necessarily have to be spaced from the facing surface of the gear 31 (31A) in a state where the biasing force of the spring washer 330 is not generated. ) May be contacted within a range that does not apply a braking force.

Further, the gear 31 (31A) is shown as being provided at the end of the screw shaft 11, but the gear 31 (31A) is not limited to this, and may rotate in association with the rotation of the spool 5 when the fishing line is fed. Good. Further, the gear 31 (31A) may be a single gear that is not connected to the screw shaft 11 or the like.

Further, the friction lining member 332 (332A) may have a concave protrusion on the opposing surface.
Alternatively, a plurality of materials may be combined in the circumferential direction.
