  However, in the conventional non-dead point mechanism, since the return plate is rotatably arranged on the handle shaft on the side of the ratchet spool, a space for accommodating the return plate is required in the handle shaft direction, and a large size is required in the axial direction. Turn into.

  In addition, since the leaf spring that urges the return plate is fixed to the ratchet, a space for housing the leaf spring is required, the ratchet becomes larger in diameter, and the tooth profile and the number of teeth of the ratchet are limited. become. When this non-dead point mechanism is operated, the leaf spring protrudes beyond the outer periphery of the ratchet, so that a space in the radial direction is required and the size is further increased in the radial direction.

  Furthermore, the number of parts such as a return plate, a pair of leaf springs, pins, leaf spring fixing screws, etc. is large, and the cost increases.

  The present invention has been made based on such circumstances, and an object thereof is to provide a fishing reel capable of automatically returning the clutch mechanism with a compact, simple and low-cost configuration with a small number of parts. To do.

  In order to achieve the above object, according to the present invention, the spool rotatably supported by the reel body is switched and held between the power transmission state and the power cutoff state, and when the handle is in the winding direction, A fishing reel provided with a clutch mechanism that automatically returns to a power transmission state by rotation, a long hole extending in an arc shape is formed in a rotating body that rotates integrally with the handle shaft, and the return pin of the clutch mechanism A fishing reel which is movable along the long hole and is prevented from coming off and attached to the rotating body, and one end of which is locked to the rotating body or the handle shaft urges the return pin in one direction. Is provided.

  In the fishing reel of the present invention, the return pin is directly movable in the elongated hole formed in the rotating body that rotates integrally with the handle shaft and is prevented from coming off, and the mounting pin is biased by a spring. The size of the shaft in the axial direction is prevented, and the clutch mechanism can be automatically restored with a compact and low-cost configuration with a small number of parts, and the gear box that accommodates the reel body winding drive mechanism is limited. Space can be used effectively.

  1-3 illustrate a fishing reel 10 according to a preferred embodiment of the present invention.

  As shown in FIGS. 1 and 2, the fishing reel 10 of this embodiment is formed as an electric reel. The reel body 12 of the fishing reel 10 is formed by attaching side plates 16a and 16b to the outer sides of a pair of integrated left and right frames 14a and 14b, and is fixed to a fishing rod via attachment legs 18. .

  The spool 20 around which the fishing line is wound is rotatably supported between the left and right frames 14a and 14b via bearings 18a and 18b, and houses a driving DC motor M and a reduction gear R therein.

  The motor M of the present embodiment is attached to the left frame 14 a via a holding portion 24 provided at one end of the motor case 22, and the power supplied via the main body side connector C is supplied from the brush 26 in the motor case 22. To the coil of the rotor 28. The motor shaft m fixed to the rotor 28 is rotatably supported by the motor case 22 via bearings 30a and 30b, and is prevented from being reversely rotated by a one-way clutch 32 provided on the brush 26 side so that manual winding driving is performed. It is possible. The motor M is controlled in operation and rotational speed by a control device (not shown).

  The speed reduction device R that decelerates the output of the motor shaft m and transmits it to the spool 20 has a first planetary speed reduction mechanism 34 disposed in the motor case 22 and a second planetary speed reduction mechanism 36 disposed in the spool 20. And when the clutch mechanism mentioned later is arrange | positioned in the power cutoff state, the resistance by the reduction gear R can be reduced.

  The first planetary reduction mechanism 34 meshes with a sun gear 34a that rotates together with the motor shaft m, an internal gear 34b that is fixed to the inner peripheral side of the motor case 22, and the sun gear 34a and the internal gear 34b. And a carrier 34c that supports a plurality of planetary gears revolving around the sun gear 34a while rotating, and the sun gear 36a of the second planetary reduction mechanism 36 is rotated through the carrier 34. The internal gear 36b of the second planetary speed reduction mechanism 36 is integrally fixed to the inner peripheral portion of the spool 20, and a carrier 36c that supports a plurality of planetary gears meshed with the sun gear 36a and the internal gear 36b is a bearing. The motor shaft m is rotatably supported via 38. The carrier 36c is fitted into a boss portion of a lid member 40 fixed to the spool 20, and a gear 40a for driving a level wind mechanism (not shown) is formed on the lid member 40. The lid member 40 is rotatably supported by a support plate 14c attached and fixed to the right frame 14b via a bearing 18b.

  In the present embodiment, the carrier 36c of the second planetary speed reduction mechanism 36 functions as a drive shaft D that rotationally drives the spool 20, and the end of the drive shaft D that protrudes from the right frame 14b toward the right side plate 16b A clutch mechanism 44 is provided that switches between the power transmission state and the power cut-off state and automatically returns to the power transmission state when the handle 42 is rotated in the winding direction when the power is cut off.

  In order to transmit the manually wound power generated by the rotation of the handle 42 to the spool 20, a pinion gear shaft 46a is disposed coaxially with the drive shaft D between the right frame 14b and the right side plate 16b, and the pinion gear 46 is disposed on the pinion gear shaft 42a. Mounted so as to be rotatable and movable in the axial direction. The pinion gear 46 is moved to the right in FIG. 1 when the clutch mechanism 44 is switched to the power cut-off state, and the engagement with the drive shaft D is released. Further, when the driving force transmission state is restored, it is moved to the fitting position shown in FIG. 1, meshes with the driving shaft D, rotates integrally, and transmits the power acting on the handle 42 to the spool 20.

  The movement of the pinion gear 46 can be performed by moving the yoke 48 engaged with the circumferential groove 46b formed in the pinion gear 46 along the pinion shaft 46a in conjunction with the switching operation of the clutch mechanism 44. When the pinion gear 46 is disposed at the mating position shown in FIG. 1, the fishing line can be wound with the clutch ON in the power transmission state, and the clutch OFF with the power cutoff state in the non-engagement position (not shown) is spool free. Rotating state. When the handle 42 is rotated from the clutch OFF state, the clutch 42 can be automatically returned to the clutch ON state via a return mechanism described later.

  The yoke 48 of the present embodiment has a short shaft in which the tip of each arm portion extending radially outward from the central portion that fits in the circumferential groove 46b of the pinion gear 46 projects from the support plate 14c attached to the right frame 14b. 48a (FIG. 2) is slidably mounted and is biased by a spring toward the support plate 14c. The clutch mechanism 34 is provided on the clutch driving member 50 that reciprocates between the support plate 14c and the yoke 48 in the direction close to and away from the pinion gear 46 indicated by the arrow S along the support plate 14c. When the clutch driving member 50 moves toward the pinion gear 46, the cam 50a moves in a direction separating the arm portion of the yoke 48 from the right frame 14b. By the movement of the yoke 48, the pinion gear 46 is moved to the right side plate 16b via the circumferential groove 46b, the engagement between the drive shaft D and the pinion gear 46 is released, and the clutch is turned off. The spool 20 can rotate freely.

  In order to move the clutch drive member 50, a link member 52b (FIG. 1) is provided on the support shaft 52a of the clutch lever 52, and an engagement pin 52c provided on the link member 52b is fitted into the elongated hole 50b of the clutch drive member 50. The clutch lever 52 and the clutch drive member 50 are connected by combining them. The clutch lever 52 is distributed and biased and held by a distribution spring 54 at each position of the clutch ON state and the clutch OFF state.

  Further, the drive gear 56 meshes with the pinion gear 46. The drive gear 56 is rotatably supported by the handle shaft 42a, and both ends of the handle shaft 42a are rotatably supported by the support plate 14c and the side plate 16b.

  When the handle shaft 42a is rotated in the direction of winding the fishing line by the handle 42 attached to the outer end portion thereof, the drive gear 56 is connected via the drag mechanism 58 inserted between the drive gear 56 and the handle shaft 42a. , And the pinion gear 46 rotates accordingly. When the clutch mechanism 44 is in the clutch ON state, the drive shaft D is rotationally driven and the spool 20 is rotated. At this time, the fishing line is wound evenly along the axial direction of the spool 20 by a level wind mechanism (not shown). The drag force of the drag mechanism 58 can be adjusted by rotating the star drag 60 mounted on the handle shaft 42 a and changing the pressing force of the spring 62.

  As shown in FIG. 3 in an enlarged manner, the inner end of the handle shaft 42a is rotatably supported by the support plate 14c via a bush 64 having a stepped structure. Removal to the side of the plate 16b is prevented. A large-diameter portion 42b that is enlarged in a flange shape is integrally formed on the inner end side of the handle shaft 42a, and a clutch return rotating body is formed on a non-circular portion formed adjacent to the large-diameter portion 42b. 66 is mounted.

  The clutch return rotator 66 is attached to the handle shaft 42a so as to be movable in the axial direction and is prevented from rotating, and functions as a rotator that rotates integrally with the handle shaft 42a. The rotating body 66 abuts on the large diameter portion 42b on the support plate 14c side, and can support the biasing force of the spring 62 acting via the drive gear 56 and the drag mechanism 58. The rotating body 66 is formed in a ratchet shape, and a gap is maintained between the rotating body 66 and the support plate 14c, and a claw-like stopper 68 (FIG. 2) mounted on the support plate 14c so as to be swingable is provided with teeth on the periphery. The parts mesh. The stopper 68 is always urged toward the rotating body 66 and allows the clutch returning rotating body 66 and the handle shaft 42a to rotate in the forward rotation direction, that is, the fishing line winding direction, and in the reverse rotation direction, that is, the fishing line feeding direction. The rotation of the is surely prevented.

  As shown in FIG. 2, the rotating body 66 automatically returns the clutch mechanism 44 to the clutch ON state in cooperation with the clutch drive member 50 when the handle 42 is rotated in the fishing line winding direction in the clutch OFF state. An automatic return mechanism is provided.

  The automatic return mechanism includes an arc-shaped long hole 70 formed in the rotating body 66, a return pin 72 that is prevented from being removed by the long hole, and a spring 74 that biases the return pin 72 in one direction. Have The long hole 70 is formed in an arc shape centered on the axis of the handle shaft 42 a, and the spring-biased return pin 72 can move along the long hole 70.

  As shown in FIGS. 2 and 3, the spring 74 is formed of a coil spring having one end 74a fixed to the rotating body 66, and the intermediate portion is wound around the handle shaft 42a, for example, with a loose degree of freedom, while the other end is wound. The pin 72 is urged toward one end side of the long hole 70 in the forward rotation direction. The spring 74 is further wound around the neck of the pin 72 and urged in the axial direction from the long hole 70 toward the support plate 14c, thereby ensuring a reliable engagement with the engagement end 50c of the clutch drive member 50. is doing. It is preferable to provide a retaining means such as an enlarged diameter portion 72a) on the right plate 16b side of the pin 72, and to form a stepped portion 70a or the like that engages with the enlarged diameter portion 72a in the elongated hole 70. Further, for example, a C ring-shaped stopper 76 may be provided to prevent the pin 72 from being drawn into the long hole 70 and moving to the right side plate 16a side.

  4 and 5 show the operation of the clutch mechanism 44 thus formed.

  For example, when performing a casting operation to feed a fishing line with a weight or the weight of a mechanism or to perform a casting operation to distantly move a mechanism, when switching from the clutch ON state to the clutch OFF state, when the clutch lever 52 is rotated from the state of FIG. The clutch driving member 50 moves in the direction indicated by the arrow S, and the engaging end 50c also moves while the cam 50a moves the yoke 48 in the axial direction.

  As indicated by a chain line in FIG. 4, when the pin 72 is disposed within the movement range of the engagement end 50 c, the engagement end 50 c is engaged with the pin 72. Further, when the clutch lever 52 is rotated and the clutch driving member 50 is further moved in the arrow S direction, the rotating body 66 is prevented from rotating backward by the stopper 68. The pin 72 moves in the elongated hole 70 against the urging force of the spring 74 together with the engaging end 50c. When the intermediate position, which is the thought point of the distribution spring 54, is exceeded, the urging force of the distribution spring 54 further moves the clutch drive member 50 in the arrow S direction, and the yoke 48 is moved by the cam 50a to drive the pinion gear 46. The pin 72 is completely separated from the axis D and at the same time, as shown in FIG. The spool 20 can rotate freely. The pin 72 is maintained in a state of being engaged with the engagement end 50 c by the biasing force of the spring 74.

  When the handle 42 is rotated in the forward rotation direction from the clutch OFF state, the rotating body 66 rotates together with the handle shaft 42a, the end of the long hole 70 is engaged with the pin 72, and the pin 72 is moved in the forward rotation direction. To do. The clutch drive member 50 is also moved in the direction opposite to the arrow S via the engagement end 50c, and the yoke 48 moves to the right frame 14b side to fit the pinion gear 46 to the drive shaft D. And it is hold | maintained in the state shown in FIG.

  Therefore, according to the fishing reel 10 described above, the return pin 72 can be directly moved and retained in the elongated hole 70 formed in the rotating body 66 that rotates integrally with the handle shaft 42a. Since the spring 74 is energized, the handle shaft 42a is prevented from being enlarged in the axial direction, and the clutch mechanism 44 can be automatically returned with a simple and low-cost configuration with a small number of parts. The limited space between the gear box in which the take-up drive mechanism is accommodated, that is, the right frame 14b and the right side plate 16a can be effectively utilized.

  6 and 7 show a modification in which the end of the coil spring 74 is fixed to the handle shaft 42a. The embodiment or modification described below is basically the same as the above-described embodiment, and therefore, the same reference numerals are given to the same parts, and the detailed description thereof is omitted.

  According to this modification, the axial length of the spring 74 is minimized, and the spring 74 can be reduced in weight, incorporated in a small space, and compact.

  FIG. 8 shows a structure in which the pin 72 is divided, and a neck portion 72 c is screwed into a main body portion 72 b disposed in the long hole 70. Since the neck portion 72c can be attached to and detached from the main body portion 72b, assembly is facilitated.

  Although the above-described embodiment or modification has been described with respect to the electric reel, it is obvious that it can also be used with a manually wound fishing reel.
