Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a fishing reel, strong external forces and impacts act on the clutch mechanism as the clutch lever is turned on and off. In particular, in a fishing reel intended for relatively large fish such as kampachi and yellowfin tuna, for example, the weight of the sinker used for casting is heavy and the tension of the line is high. For this reason, the movement of the angler who operates the clutch tends to be forceful, and it is necessary to sufficiently increase the strength of the clutch part. Further, a fishing reel is required not only to have high strength but also to have high design quality.

[0005] The present invention has been made paying attention to the above-described problems, and an object thereof is to provide a fishing reel capable of appropriately improving the strength of a clutch mechanism.

Means for Solving the Problems

[0006] In order to solve the above-described problems, a fishing reel of the present invention is a fishing reel provided with a spool around which a fishing line is wound and capable of being wound and driven by a drive motor and / or a manual handle provided in a reel body, and having a clutch mechanism for switching the spool between a power transmission state and a power cut-off state, wherein the clutch mechanism includes a clutch lever, an operating member connected to the clutch lever and rotationally displaced together with the clutch lever, a rigid member that supports the clutch lever and the operating member, and an operating force transmission member that is supported by the rigid member, has lower rigidity than the rigid member, abuts against the rigid member, and interferes with the operating member that rotates and displaces to stop the operating member.

Effects of the Invention

[0007] According to the present invention, it is possible to provide a fishing reel capable of appropriately improving the strength of a clutch mechanism.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0010] Figures 1 to 3 show an electric fishing reel 1 as an embodiment of the present invention. Figure 1 is a perspective view of the electric fishing reel 1, and is drawn by attaching reference numerals to a design model with ridgelines created by CAD. Figure 2 is a plan view showing the internal structure, and Figures 3 and 4 are views showing an enlarged main part of Figure 2. Figure 3 is a view showing the power transmission state (clutch ON), and Figure 4 is a view showing the power cut-off state (clutch OFF).

[0011] As shown in Figures 1 and 2, the electric fishing reel 1 of this embodiment includes a reel body 5 configured by attaching outer plates 4a and 4b to left and right frames 3a and 3b. A manual handle 6 for winding operation is provided on one side plate (right side plate 4b) side that constitutes the reel body 5. Between the left and right frames 3a and 3b that constitute the reel body 5, a spool 7 around which fishing line is wound is rotatably supported. Also, a drive motor 8 is held between the left and right frames on the front side of the spool 7. The spool 7 is rotationally driven in the fishing line winding direction through a power transmission mechanism described later by the winding operation of the manual handle 6 and the rotational drive of the drive motor 8.

[0012] The spool 7 is provided with a fishing line winding barrel portion 7a around which the fishing line is wound, and flanges 7b and 7c for regulating the wound fishing line are formed at both ends of the fishing line winding barrel portion 7a. Further, the spool 7 is fixed to the spool shaft 7s, and both ends of the spool shaft 7s are supported via bearings 10 with respect to the respective frames 3a and 3b, so as to be rotatably supported between the frames.

[0013] Furthermore, a locking portion 7h having a non-circular cross section is formed at the end portion on the right side plate side of the spool shaft 7s so that the engaging portion 40a of the clutch operating member 40 of the clutch mechanism described later is engaged and disengaged. In this case, the locking portion 7h has a function as a power transmission portion so that the clutch operating member 40 and the spool 7 rotate integrally, and is constituted by, for example, a non-circular cross-sectional concave portion, convex portion, concavo-convex portion, or the like.

[0014] The rotation driving force from the manual handle 6 and the drive motor 8 is input to the spool 7 via the power transmission mechanism 12. In this case, the power transmission mechanism 12 has a configuration including a speed reduction mechanism 15 for reducing the rotation driving of the drive motor 8 and a clutch mechanism 18 for switching the power transmission in the power transmission mechanism 12 between a power transmission state and a power cut-off state. Hereinafter, the configurations of these power transmission mechanism 12, speed reduction mechanism 15, and clutch mechanism 18 will be described.

[0015] The power transmission mechanism 12 of the present embodiment is intensively installed on the right frame (right side plate) 4b side of the reel body 5, and includes a handle shaft 6a that rotatably supports the manual handle 6, a drive gear 6b attached to the handle shaft 6a, a connecting gear 20 that meshes with the drive gear 6b and is connected to the speed reduction mechanism 15, and a belt 50 interposed between the speed reduction mechanism 15 and the clutch mechanism 18.

[0016] The reduction mechanism 15 is configured to reduce the rotational drive force of the drive motor 8 using a planetary gear mechanism provided in parallel, and includes a first planetary gear 32 and a second planetary gear 33 that mesh with a first sun gear 30 and a second sun gear 31, respectively, that are provided in parallel on the drive shaft 8a of the drive motor 8. In this case, the first sun gear 30 is fixed to the drive shaft 8a, and the second sun gear 31 is free to rotate. Each planetary gear 32, 33 meshes with internal teeth 35a formed on an output rotor 35, and a first carrier 32a that supports the first planetary gear 32 is fixedly connected to the second sun gear 31. Furthermore, a second carrier 33a that supports the second planetary gear 33 is fixedly connected to the connecting gear 20.

[0017] The handle shaft 6a is provided with a reverse rotation prevention mechanism 6c, which prevents the manual handle 6 from rotating in conjunction with the drive motor 8 when it is driven to rotate. In this embodiment, the reverse rotation prevention mechanism 6c is configured as a reverse rotation prevention ratchet attached to the handle shaft 6a, but it may also be configured as a one-way clutch. In addition, a one-way clutch 8d is attached to the protruding portion on the left side plate of the drive shaft 8a of the drive motor 8 to prevent free rotation when the manual handle 6 is operated for rewinding and to transmit power to the spool 7 side.

[0018] The rotational driving force of output rotor 35 constituting speed reduction mechanism 15 is transmitted to input rotor 39 associated with clutch mechanism 18, and in this embodiment, the transmission of rotational driving force between them is performed via power transmission belt 50. That is, grooves 35e and 39e are formed on the outer circumferential surfaces of output rotor 35 and input rotor 39, respectively, and power is transmitted by winding belt 50 around these grooves.

[0019] The clutch mechanism 18 is rotatably supported between the right frame 3b and the right side plate 4b via a pair of bearings 41, and is also supported so as to be movable along the axial direction. It includes an axially-shaped clutch operating member 40, an operating plate 42 engaged with the clutch operating member 40, a clutch plate 43 engaged with the operating plate 42 to move the clutch operating member 40 in the axial direction, and an operating lever (clutch lever) 45 for rotationally driving the clutch plate 43. Note that a non-circular outer peripheral portion formed on one side of the clutch operating member 40 is fitted in a non-circular circumferential portion inside the input rotating body 39 to prevent rotation.

[0020] On the spool side of the clutch operating member 40, an engaging portion 40a is formed to fit into a locking portion 7h having a non-circular cross-section formed on the spool shaft 7s. The engaging portion 40a and the locking portion 7h are detachable and have a non-circular cross-sectional fitting relationship as described above. When they are fitted together, the spool 7 rotates integrally via the spool shaft 7s when the clutch operating member 40 is rotationally driven.

[0021] The operating plate 42 is attached to the middle portion of the clutch operating member 40 and constantly biases the clutch operating member 40 toward the spool side. In this state, as shown in FIG. 3, the engaging portion 40a of the clutch operating member 40 is fitted into the locking portion 7h of the spool shaft 7s to enter the power transmission state (clutch ON). Then, when the clutch operating lever (hereinafter referred to as the "clutch lever") 45 is rotationally operated, as shown in FIGS. 3 and 4, the eccentric protrusion 45b of the operating body 45a that rotates integrally with the clutch lever 45 engages with an engaging elongated hole 43b formed at the end of the clutch plate 43, sliding the clutch plate 43 toward the axial center side of the clutch operating member 40. The cam member 43a provided on its surface pushes up the operating plate 42 against the biasing force, sliding the clutch operating member 40 toward the right side plate side. In this state, the engaging portion 40a of the clutch operating member 40 disengages from the locking portion 7h and enters the power transmission interruption state (clutch OFF) as shown in FIG. 3. The return from the clutch OFF state to the clutch ON state is achieved by a known return mechanism through the winding operation of the manual handle 6 or the rotational operation of the clutch lever 45, etc.

[0022] Here, FIGS. 2 to 4 schematically show the basic configuration and basic structure with respect to the actuator 45a and the eccentric projection 45b connected to the clutch lever 45. Details regarding the clutch lever 45 and the actuator 45a are shown in FIGS. 5 to 9.

[0023] FIG. 5 shows the clutch lever 45 and the support plate 51 that supports the clutch lever 45 from the outside. The support plate 51 is attached to the outside of the right side plate 4b and constitutes a part of the external design of the electric fishing reel 1. The handle shaft 6a of the manual handle 6 penetrates through the support plate 51. In FIGS. 2 to 4, illustration of the boundary portion between the right side plate 4b and the support plate 51 is omitted.

[0024] FIG. 6 shows the inside of the support plate 51, and FIG. 7 shows an enlarged view of a part of FIG. 6. FIG. 8 shows the clutch rotation mechanism portion 52 disassembled. The clutch rotation mechanism portion 52 enables the clutch lever 45 to rotate (pivot) at a predetermined angle.

[0025] As shown in FIG. 5, the clutch lever 45 is disposed outside the support plate 51. As shown in FIGS. 6 to 8, a screw 64 for attaching the clutch lever is screwed into the tip portion 62 (FIG. 8) at the base end portion 60 of the clutch lever 45 from the inside of the support plate 51. In FIG. 8, illustration of the thread groove portion of the screw 64 for attaching the clutch lever and the screw hole provided in the tip portion 62 of the clutch lever 45 is omitted.

[0026] As shown in FIG. 7, the screw 64 for attaching the clutch lever is inserted into the actuator (claw member) 45a and the bearing member 68. The actuator 45a and the bearing member 68 are sandwiched between the head portion 70 of the screw 64 for attaching the clutch lever and the support plate 51 as shown in FIG. 6. And the actuator 45a and the bearing member 68 are supported by the support plate 51 together with the clutch lever 45. Here, the actuator 45a is schematically shown in FIGS. 3 and 4 described above. Also, the bearing member 68 is not shown in FIGS. 3 and 4 described above.

[0027] Among these, the bearing member 68 is formed in a plate shape with irregularities, and the material of the bearing member 68 is a synthetic resin having sufficient wear resistance and lubricity. The bearing member 68 has a cover portion 72 formed in a rectangular bag shape, a hole portion 74 (Fig. 8) formed in a perfect circle shape, a columnar boss portion 76, and the like. The cover portion 72 and the boss portion 76 are integrally formed on the bearing member 68.

[0028] The cover portion 72 has an inner shape that matches the rectangular convex portion 78 formed on the support plate 51, and is covered on a part of the convex portion 78. The convex portion 78 is integrally formed on the support plate 51. The material of the support plate 51 including the convex portion 78 is metal. The convex portion 78 projects perpendicularly from the flat portion 80 formed inside the support plate 51. An oval portion 82 adjacent to the flat portion 80 is formed inside the support plate 51. The oval portion 82 is, for example, an oval concave portion.

[0029] The shape of the convex portion 78 is generally rectangular, but the curved surface portion 84 (Fig. 7), which is a part of the convex portion 78, is continuous with the inner peripheral wall 86 in the oval portion 82. Furthermore, when the flat portion 80 is viewed from the front, the shape of the convex portion 78 is visually recognized as, for example, a quadrilateral shape (which can also be said to be a trapezoidal shape).

[0030] The cover portion 72 covered on such a convex portion 78 has a first side portion 88, a second side portion 90, a third side portion 92 that constitute three side surfaces, and a flat portion 94 located at the tip (projecting end), as shown in Figs. 7 and 8. The first side portion 88 to the third side portion 92 and the flat portion 94 are integrally molded and continuous. The first side portion 88 to the third side portion 92 are joined and reinforced via the flat portion 94. Also, the first side portion 88 and the third side portion 92 are joined and reinforced via the third side portion 92 and the flat portion 94.

[0031] The cover portion 72 is placed over the convex portion 78 of the support plate 51 as described above, and partially covers the convex portion 78 in a state of being substantially in contact with the convex portion 78. Further, the cover portion 72 is locked to the convex portion 78 in a state of being fitted into the convex portion 78. Then, the position and orientation of the bearing member 68 are determined to be constant by the shape matching between the cover portion 72 having the first side portion 88, the second side portion 90, the third side portion 92, and the flat portion 94, and the rectangular projection-shaped convex portion 78.

[0032] In the examples of FIGS. 6 and 7, a part of the convex portion 78 (here, about half to a little more than half) is exposed from the cover portion 72. However, the present invention is not limited to this, and for example, most or all of the convex portion 78 may be covered by the cover portion 72.

[0033] The base end portion 60 of the clutch lever 45 passes through the hole portion 74 (FIG. 8) of the bearing member 68. When the clutch lever 45 is rotationally displaced, the base end portion 60 rotates and displaces while sliding inside the hole portion 74.

[0034] Subsequently, the above-described actuating body 45a is stacked on the bearing member 68. Most of the actuating body 45a is formed in a disc shape and has the above-described eccentric projection 45b (FIGS. 3, 4, 6 to 8). A long hole portion 96 (FIG. 8) is formed at the center of the plate surface of the actuating body 45a, and the long hole portion 96 penetrates the actuating body 45a.

[0035] The tip portion 62 of the base end portion 60 of the clutch lever 45 is inserted into the long hole portion 96. A straight portion 98 is formed at the tip portion 62 of the clutch lever 45 by chamfering. The shape of the long hole portion 96 in the actuating body 45a is matched with the shape of the tip portion 62 of the clutch lever 45, and the tip portion 62 can be locked to the linear edge portion 100 in the long hole portion 96 with substantially no gap.

[0036] When the clutch lever 45 rotates and displaces, the actuator 45a also rotates and displaces integrally while being locked to the tip portion 62 of the clutch lever 45. That is, the tip portion 62 of the clutch lever 45 functions as a key (hook) or a joint, and the rotational force of the clutch lever 45 is transmitted to the actuator 45a via the tip portion 62. As a result, the actuator 45a rotates and displaces together with the clutch lever 45.

[0037] The actuator 45a has an arcuate notch portion 102 in a part of its outer peripheral edge, and the cover portion 72 of the bearing member 68 enters together with the convex portion 78 inside the notch portion 102 (FIGS. 6 and 7). Further, the actuator 45a and the bearing member 68 are connected via a torsion coil spring 104 (shown by a two-dot chain line in FIG. 7). And in a state where the clutch lever 45 is not rotating and displacing, the actuator 45a receives the biasing force of the torsion coil spring 104 and, as shown in FIG. 7, causes one edge portion 102a of the notch portion 102 to interfere with the first side portion 88 of the cover portion 72.

[0038] On the other hand, when the clutch lever 45 rotates and displaces, the actuator 45a also rotates and displaces as shown by the arrow A while resisting the biasing force of the torsion coil spring 104. At this time, the positional relationship between the notch portion 102 of the actuator 45a and the cover portion 72 of the bearing member 68 changes relatively.

[0039] When the rotational displacement amount of the actuator 45a reaches a predetermined amount (the angle at which the notch portion 102 extends), the other edge portion 102b of the notch portion 102 interferes with the third side portion 92 of the cover portion 72, and the actuator 45a stops. And as described above, the eccentric projection 45b of the actuator 45a slides the clutch plate 43 (FIGS. 2 and 3) toward the axial center side of the clutch operating member 40. As a result, the engaging portion 40a of the clutch operating member 40 disengages from the locking portion 7h, and as shown in FIG. 4, the power transmission is interrupted (clutch OFF).

[0040] When the clutch lever 45 is released, the biasing force of the torsion coil spring 104 causes the actuator 45a to return in the reverse direction as indicated by arrow B (Fig. 7). Then, when the edge 102a of the aforementioned notch 102 interferes with the cover portion 72 of the bearing member 68, the clutch lever 45 returns to its original position and stops.

[0041] According to the electric fishing reel 1 provided with such a clutch rotation mechanism portion 52 and a clutch mechanism 18, a bearing member 68 is provided. The bearing member 68 is supported by the support plate 51, has lower rigidity than the support plate 51, abuts against the support plate 51, and interferes with the actuator 45a that rotates and displaces to stop the actuator 45a. Therefore, for example, the operating force applied to the clutch lever 45 by the user is transmitted to the relatively high-rigidity support plate 51 via the bearing member 68. As a result, the operating force of the user can be borne by high-rigidity components, and sufficient strength can be obtained.

[0042] Further, the bearing member 68 includes a cover portion 72. The cover portion 72 is locked to the convex portion 78 formed on the support plate 51 and interferes with the actuator 45a that rotates and displaces. Therefore, the operating force transmission path from the bearing member 68 to the support plate 51 can be formed reliably and easily.

[0043] Further, the cover portion 72 that interferes with the actuator 45a has a first side portion 88 and a third side portion 92, and the first side portion 88 and the third side portion 92 are reinforced by a second side portion 90 and a flat portion 94. Therefore, higher rigidity can be ensured for the cover portion 72.

[0044] Further, the cover portion 72 is formed in a bag shape and is put on the convex portion 78. Therefore, it is possible to easily combine the bearing member 68 with the convex portion 78 and cover the convex portion 78. [[ID='17']]
