  However, according to the former electric reel, since the electric motor is housed in the spool, the winding capacity of the fishing line to be wound becomes extremely small because the spool diameter is large, and fishing in the deep sea is difficult. There is a risk that it may cause troubles during trolling. On the other hand, according to the latter electric reel, since the electric motor is provided in the reel body, a spool having a small diameter can be adopted and the winding capacity of the fishing line can be increased. Apart from the power transmission mechanism and the planetary gear mechanism for the spool, a means such as a planetary gear mechanism for transmitting power from the electric motor to the spool must be provided, resulting in a complicated overall structure and failure. However, there is a problem that the product is expensive.

  Furthermore, in any of the above-described electric reels, since the electric motor is incorporated in the reel body or the spool, it is difficult not only to replace the electric motor at the time of repair, but also to have excellent performance. There is also a problem that it is difficult to employ an electric motor.

  The present invention has been made in view of such problems, and an object of the present invention is to arrange an electric motor outside the reel body to enable use of a spool having a large fishing line winding capacity. The power transmission mechanism to the spool by the electric motor is not separately provided in the reel body, the power transmission mechanism by the manual handle is shared to simplify the overall structure, and the conventional dual-bearing manual reel has been used. It is to provide a fishing reel that can be easily modified to an electric reel.

  In order to achieve the above object, a fishing reel according to the present invention has a spool rotatably supported between both side plates of a reel body and a handle on an outer peripheral portion of one side plate. A handle is attached via a first one-way clutch that supports the shaft rotatably and transmits a rotational force to the handle shaft in only one direction. By rotating the handle, the spool is connected to the fishing line via a power transmission mechanism. In a fishing reel configured to rotate only in the winding direction, an external frame having an electric motor attached to the reel body is detachably mounted and the handle shaft is attached in the same direction as the first one-way clutch. The second one-way clutch that transmits the rotational force only to the motor is mounted, and the rotational force of the electric motor is reduced to the second one-way clutch. It is configured to be transmitted to the handle shaft by.

The first one-way clutch and the second one-way clutch that can transmit the rotational force only to the first one-way clutch are mounted, and the rotational force of the steering motor is transmitted to the first one-way clutch, and the rotational force of the electric motor is transmitted to the second one-way clutch. Therefore, it is possible to share a power transmission mechanism that rotates the spool in the winding direction via the handle shaft, both when winding with the electric motor and when winding manually. To facilitate maintenance and inspection, reduce the occurrence of failures, and provide products at low cost. Can.

  Further, winding of the fishing line by driving the electric motor and winding of the fishing line by rotating the handle can be performed separately through the common power transmission mechanism, and by rotating the handle while driving the electric motor. The winding force by the electric motor can be assisted by the winding force by manual winding.

  In addition, since the electric motor is mounted on the outside of the reel unit, the electric motor can be easily maintained and inspected, and can be easily replaced with a new electric motor. Can be replaced with a powerful electric reel. Furthermore, the outer frame frame is mounted on a commercially available manual double-bearing type reel or a manual double-bearing type reel in use, an electric motor is attached to the outer frame frame, and the rotating shaft of the electric motor is mounted. By connecting to the second one-way clutch mounted on the handle shaft, the manually wound reel can be easily configured as an electric reel.

  According to the second aspect of the invention, since the one-way bearings are used as the first and second one-way clutches, the first and second one-way clutches are arranged in the length direction of the handle shaft with respect to the handle shaft. Can be easily connected to the handle and the electric motor by connecting them in series with each other, and the unidirectional rotational force generated by the electric motor and handle during winding is transferred from the unidirectional bearing through the handle shaft and the power transmission mechanism. The rotation can be reliably transmitted to the spool side, and the rotation of the rotation force to the handle shaft side can be interrupted with respect to rotation in the other direction, and the handle can be freely returned to the predetermined operation position.

As is well known, the spool 3 is integrally formed with disc-shaped flange portions 3b and 3c having a smaller diameter than the both side plates 1a and 1b at both ends of a small-diameter cylindrical shaft portion 3a on which the fishing line A is wound. The spool shaft 2 is inserted into the cylindrical shaft portion 3a, and both end portions of the cylindrical shaft portion 3a are supported on both end portions in the length direction of the spool shaft 2 via the bearings 12 and 12, respectively.

  A handle shaft 4 is rotatably supported on the outer peripheral portion of the one side plate 1a of the reel body 1 so as to penetrate between the inner and outer surfaces of the side plate 1a. The handle shaft 4 extends outward from the side plate 1a. The first one-way clutch 5 and the second one-way clutch 6 are mounted on the projecting portion projecting to the outside with the first one-way clutch 5 on the outside, that is, the projecting end side. These first and second one-way clutches 5 and 6 may be clutches composed of a ratchet mechanism, or roller clutches that prevent reverse rotation by biting the rollers into the wedge-shaped space, As shown in FIG. 5, inner cages 5b and 6b and outer cages 5c and 6c are arranged on the inner circumferential surfaces of the outer rings 5a and 6a, respectively, and the inner and outer cages 5b and 5c and 6b and 6c are circumferentially arranged. The holding windows 5d and 6d provided at small intervals are used with unidirectional bearings in which sprags 5e and 6e with a cross-sectional shape are swingably supported, and the inner surfaces of the sprags 5e and 6e are handled as handles. The handle 4 is fitted into the handle shaft 4 while being in contact with the shaft 4.

  As is well known, the sprags 5e and 6e of this one-way bearing are formed by forming the outer peripheral surface of the handle shaft 4 and the inner and outer surfaces in contact with the outer rings 5a and 6a as arcuate cam surfaces, respectively. When rotating in one direction, the height increases and acts in the direction of biting into the handle shaft 4 and the outer rings 5a, 6a. The outer rings 5a and 6a are configured to be idled via the handle shaft 4. That is, when rotational force is applied to the handle shaft 4 in the direction in which the sprags 5e and 6e bite into the outer rings 5a and 6a, the rotational force is transmitted to the handle shaft 4 and the handle shaft 4 is When the outer rings 5a and 6a are rotated in the opposite direction to the above, the sprags 5e and 6e prevent the rotational force from being transmitted to the handle shaft 4, and the handle shaft 4, the outer rings 5a and 6a are idle.

  A proximal end short cylindrical body portion 7a of the handle 7 is provided on the outer ring 5a of the first one-way clutch 5 fitted to the protruding end side of the handle shaft 4 from the one side plate 1a in the reel body 1, that is, the outer end portion. A handle 7b for rotation operation is attached to the tip of the handle 7 while being fitted together. On the other hand, a timing belt pulley 8a is fitted to the outer ring 6a of the second one-way clutch 6 which is in parallel with the first one-way clutch 5 and is fitted to the inner side of the protruding portion of the handle shaft 4. A timing belt 8c is stretched endlessly between the timing belt pulley 8a and the timing belt pulley 8b fixed to the rotating shaft 9a of the electric motor 9 to constitute a rotational force transmission mechanism 8 from the electric motor 9 to the handle shaft 4. ing.

  The electric motor 9 is detachably attached to an external frame 10 that is detachably attached to the rear side of the reel body 1. Specifically, the external frame 10 is composed of double-sided frames 10a and 10b each having its front end edge attached to the outer surface of the rear peripheral part of the outer peripheral part of both side plates 1a and 1b of the reel body 1 by several bolts 13, and the reel The electric motor 9 is interposed between the opposing surfaces of the both side frames 10a and 10b projecting rearward from both sides of the rear peripheral portion of the main body 1, and both end surfaces of the electric motor 9 are numbered on the both side frames 10a and 10b. The rotary shaft 9a of the electric motor 9 is protruded outward from the one-side frame 10a and the timing belt pulley 8b is fitted to the rotary shaft 9a. It has a structure.

  Further, the rotating shaft 9a protruding outward from the one side frame 10a in the external frame 10 is detachably fixed together with the electric motor 9 by the bolt 14 on the outer surface of the one side frame 10a. The cover 15 is covered with a switch / driving force operating knob 16 of the electric motor 9. The electric motor 9 is provided with a power cable connection terminal 9b (shown in FIG. 2), and a tension pulley 8d of a timing belt 8c is rotatably supported on the outer surface of the one side frame 10a. Yes. A cap body 18 is detachably attached to the end surface of the handle shaft 4 by a bolt 17. The cap body 18 presses the outer end surface of the first one-way clutch 5 through a washer 19, thereby The second one-way clutches 5 and 6 are prevented from coming off from the handle shaft 4 and are mounted at predetermined positions on the protruding portions protruding from the one side plate 1a of the reel body 1 through washers 19 '.

  As the power transmission mechanism 20 for transmitting the rotational force in one direction of the handle shaft 4 to the spool 3, a well-known mechanism can be adopted. For example, as shown in FIG. The inner end of the handle shaft 4 protruding inward from the inner surface and the one end of the spool shaft 2 are connected to each other via a gear mechanism 20a meshed with each other, and the spool shaft is rotated by one-way rotation of the handle shaft 4. 2 is configured to rotate in the direction of winding the fishing line, which is opposite to the handle shaft 4, and a drag mechanism 20b is disposed on the other end side of the spool shaft 2.

  Also in this drag mechanism 20b, a well-known mechanism can be adopted similarly to the meshing gear mechanism 20a of the power transmission mechanism 20, and in FIG. 1, the brake disc 20b1 fixed to the other end of the spool shaft 2 is used. Several friction plates 20b2 are interposed between the spool 3 and the other end surface of the spool 3, and a rotating shaft 20b3 is screwed into the central portion of one side plate 1a of the reel body 1 so as to be able to advance and retract. A drag force adjusting lever 20b4 is fixed to the projecting end of the projecting rotating shaft 20b3, and the drag force adjusting lever 20b4 is operated to rotate in one direction and the other direction so that the rotating shaft 20b3 is attached to the spool shaft 4. The braking circle is moved forward and backward in the length direction, and the spool shaft 2 that integrally connects the rotating shaft 20b3 and one end is moved in the length direction by the amount of advancement and retraction of the rotating shaft 20b3. Spool by sandwiching the friction plate 20b2 between the plate 20b1 and the other side of the spool 3 The rotational force is transmitted from the shaft 2 to the spool 3 and the transmission of the rotational force by releasing the clamping is performed. Although the reel body 1 is provided with a traverse mechanism that reciprocates in the length direction of the spool 3 by the rotation of the handle shaft 4, its illustration and description are omitted.

  With this configuration, at the time of fishing, first, the drag adjusting lever 20b4 of the drag mechanism 20b in the power transmission mechanism 20 is set in a direction to unfasten the friction plate 20b2 between the brake disc 20b1 and the other side surface of the spool 3. When the rotation is made, the transmission of the rotational force from the spool shaft 2 to the spool 3 is released, and the spool 3 freely rotates around the spool shaft. In this state, the fishing line wound around the spool 3 is fed out while the spool shaft 3 is rotated. After that, the drag adjusting lever 20b4 is rotated in the opposite direction to the above, and the clamping force of the friction plate 20b2 between the braking disk 20b1 and the other side of the spool 3, that is, the drag force is determined according to the size and type of the fish. adjust.

  Next, when it is desired to rewind the fed fishing line by an appropriate length, the first one-way clutch 5 or the second one-way is operated by rotating the electric motor 9 or rotating the handle 7 in the same direction as the electric motor 9. The clutch 6 is locked to the handle shaft 4 and its rotational force is applied to the spool 3 via the spool shaft 2 and the drag mechanism 20b from the meshing gear mechanism 20a of the power transmission mechanism 20 as a rotational force in the direction opposite to the direction of feeding the fishing line. Can transmit and rewind the fishing line.

  Further, when a fish is caught in the mechanism, a tensile force is generated in the fishing line, which acts as a force to rotate the spool 3 in the direction of feeding the fishing line, and the acting force is the drag mechanism 20b, the spool shaft 2, the meshing gear. An attempt is made to rotate the handle shaft 4 in the direction opposite to the winding direction via the mechanism 20a, but the sprags 5e of the one-way bearings which are the first and second one-way clutches 5 and 6 in this direction. 6e rotates in the direction to bite into the outer peripheral surface of the handle shaft 4 and the outer rings 5a and 6a, respectively, thereby preventing the handle shaft 4 from rotating, and therefore preventing the spool 3 from rotating in the feeding direction. When a strong tensile force is applied by the fishing line, the spool 3 rotates in the direction of feeding the fishing line against the frictional force of the drag mechanism 20b. In this case, the drag force adjusting lever 20b4 may be further tightened to increase the clamping force of the friction plate 20b2.

  By driving the electric motor 9 or manually rotating the handle 7, the first one-way clutch 5 or the second one-way clutch 6 is locked to the outer peripheral surface of the handle shaft 4, and the handle shaft 4 is rotated in one direction. Then, the rotational force is transmitted from the meshing gear mechanism 20a of the power transmission mechanism 20 to the spool 3 via the spool shaft 2 and the drag mechanism 20b, and the spool 3 is rotated in the take-up direction to catch the fish that has been eaten by the device. Pull up to catch the fish. At this time, since the electric motor 9 is mounted on the external frame 11 projecting toward the rear side of the reel body 1, that is, toward the hand of the fisherman, the hand operation of the knob 16 of the electric motor 9 is performed. Can be done smoothly.

  Further, by rotating the handle 7 manually while rotating the spool 3 in the winding direction by the power of the electric motor 9, a strong rotational torque is applied to the handle shaft 4 via the first and second one-way clutches 5 and 6. And the winding force of the spool 3 by the electric motor 9 can be assisted.

  Further, when the first and second one-way clutches 5 and 6 are difficult to use due to wear or the like, the cap body 18 attached to the shaft end of the handle shaft 4 is removed, and then the handle shaft 4 is attached to the handle shaft 4. The attached handle 7 and the timing belt pulley 8a are sequentially removed from the handle shaft 4, and the first and second one-ways are fitted into the proximal end short cylinder 7a and the timing belt pulley 8a of the handle 7, respectively. The clutches 5 and 6 may be replaced. At this time, if the handle 7 and the timing belt pulley 8a are rotated in the direction opposite to the fishing line winding direction, the lock with the handle shaft 4 is released, and the handle 7 and the timing belt pulley 8a are simply removed from the handle shaft 4. Can be extracted.

  Furthermore, since the electric motor 9 is mounted to the reel body 1 through the external frame 10, not only maintenance and inspection are easy, but also use of a spool diameter that can increase the capacity of the line to be wound. In addition, it can be easily detached from the external frame 10 and can be replaced with an electric motor having excellent performance. Further, by attaching the external frame 10 to a conventional dual-bearing manual reel, it can be easily modified to an electric reel.
