Description

  The present invention relates to an electric fishing reel provided with a spool drive motor that winds and drives a spool rotatably supported by a reel body.

  In general, an electric fishing reel is configured to transmit power of a spool drive motor (hereinafter referred to as a drive motor) provided in a reel body to a spool via a speed reduction mechanism including a planetary gear. The power transmission path is provided with a clutch mechanism for switching the spool to both a fishing line winding state and a fishing line releasing state (spool free state). Furthermore, the spool is wound not only by driving the drive motor but also by manual operation. The reel body is provided with a manual handle so that it can be driven, and the spool can be wound up and driven via the clutch mechanism.

  Unlike conventional dual-bearing reels, the fishing electric reel has a reduction mechanism consisting of planetary gears in the spool power transmission path, so the clutch mechanism is switched to the fishing line release state (spool free state; clutch OFF). However, some gears such as planetary gears rotate together with the spool, causing rotational frictional resistance due to the meshing of the gears, resulting in poor spool-free performance, and the problem that the mechanism cannot be delivered quickly remains. It was.

Therefore, the drive coupling mechanism of the drive motor is interposed in series in the manual take-up drive mechanism from the manual handle to the spool, and the connection between the manual take-up drive mechanism and the spool is cut off to reduce the rotational frictional resistance of the spool. An electric reel for fishing is proposed in Patent Document 1.
JP 2002-145

  In the configuration of the first embodiment in the invention disclosed in Patent Document 1 described above, when the clutch is turned off, the second driving gear moves in the axial direction, the clutch engaging portion of the spool is disengaged, and the spool free state is established. However, during the clutch-on drive motor and manual winding drive, the second driving gear is rotatably fitted on the outer periphery of the drive shaft, resulting in rotational frictional resistance and lowering the winding efficiency. Further, in the configuration of the second embodiment, since the first driving gear is fitted to the outer periphery of the spool when the clutch is OFF, rotational friction resistance is generated in the spool that rotates integrally with the spool shaft, and the spool-free performance is deteriorated. In other words, the conventional technology disclosed in Patent Document 1 is configured to improve the spool-free performance when the clutch is turned off and reduce the winding rotation resistance when the clutch is turned on in the fishing electric reel. is not.

  Further, since the power transmission unit of the drive motor is interposed in series in a power transmission system that winds and drives the handle, the structure becomes complicated. Furthermore, the drive coupling mechanism and the manual take-up drive mechanism, etc. of the drive motor are concentrated and arranged in series on one side plate side of the reel body, resulting in a bulky and weight-biased result. As a result, there is a problem that the balance is poor and the operability is lowered. Since various drive members are concentrated and arranged on one side plate side of the reel body, there is a problem that the assemblability is poor and the maintainability is also poor.

  The present invention has been made paying attention to the above-described problems, and provides an electric reel for fishing that can improve the spool-free performance when the clutch is OFF and reduce the winding rotation resistance when the clutch is ON. Objective. Another object of the present invention is to provide an electric fishing reel in which various drive members are arranged on both sides of the reel body in a well-balanced manner.

  In order to achieve the above-described object, an electric fishing reel according to the present invention includes a spool provided rotatably on a drive shaft provided between side plates of a reel body via a bearing, the drive shaft and the spool. And a spool drive motor provided on the reel body, and the power of the spool drive motor is transmitted to the spool via the drive shaft and the power transmission mechanism. In this configuration, the power transmission mechanism includes an internal gear that meshes with the planetary gear, can rotate integrally with the spool, and can be engaged with and disengaged from the spool by an external operation. .

  In the configuration described above, the driving force by the spool drive motor is transmitted to the spool via the drive shaft and the power transmission mechanism including the internal gear. Further, when the spool is allowed to rotate freely so as to release the fishing line, the internal gear that can rotate integrally with the spool is disengaged from the spool. That is, in the spool-free state, the spool is completely separated from the power transmission mechanism (planetary gear) having the internal gear, so that it can rotate without any resistance and the spool-free performance is improved.

  ADVANTAGE OF THE INVENTION According to this invention, the electric reel for fishing which can aim at the improvement of the spool free performance at the time of a clutch OFF, and reduction of winding-up rotation resistance at the time of a clutch ON can be obtained. Further, according to the configuration of the present invention, in addition to the above-described effects, in the case of the fishing reel that can wind the fishing line on the spool by the spool driving motor and the winding operation of the handle, The power transmission system extending from the steering wheel to the spool can be distributed and arranged on the left and right side plates of the reel main body, and the balance of the reel main body can be improved.

  The drive motor 10 includes a left drive shaft 13a protruding to one end side (left frame 3a side) and a right drive shaft 13b protruding to the other end side (right frame 3b side). On the right drive shaft 13b side, there is a one-way clutch 14 as a reverse rotation prevention mechanism that allows only rotation of the drive motor in the direction of winding the fishing line between the lid 9a screwed to the motor case 9. A motor power transmission mechanism 15 for transmitting the output of the drive motor 10 to the spool side is connected to the left drive shaft 13b side.

  The motor power transmission mechanism 15 is disposed between the left frame 3a and the left side plate 5a, and transmits the output of the drive motor to the input drive gear 17 attached to the left end portion of the drive shaft 6 so as to drive the drive shaft 6. As long as it is known, the power transmission may be performed by a configuration using a gear train or the transmission using a belt. Further, a reduction mechanism for decelerating the motor output may be connected to or incorporated in the motor power transmission mechanism 15. As is well known, this speed reduction mechanism can be configured as a part of the motor power transmission mechanism 15 by a planetary gear mechanism, a combination of a plurality of gears having different gear ratios, and the like. It may be incorporated in the drive motor 10 or in the motor case 9.

  As shown in FIG. 2, a power transmission mechanism 20 that transmits the rotation of the drive shaft 6 to the spool is disposed on the right frame side of the drive shaft 6. The power transmission mechanism 20 includes a sun gear 22 that is fixed to the drive shaft to prevent rotation between the drive shaft 6 and the spool 7, and a plurality of (three in the present embodiment) that revolve by meshing with the sun gear 22. ), The carrier 24 that rotatably supports the planetary gear, and the planetary gear 23, and the end surface of the spool 7 is engaged with the spool 7 by the following configuration so as to be rotatable integrally with the spool 7. And an internal gear 25 that is detachably mounted.

  Specifically, as shown in FIGS. 3, 7, and 8, an annular protrusion 7 a is formed on the end surface of the spool 7, and the protrusion 7 a has a predetermined interval (in this embodiment, Fitting recesses 7b are formed at two positions at intervals of 180 degrees. On the other hand, the internal gear 25 includes a circumferential wall 25a sized to enter the inside of the annular protrusion 7a, and a tooth portion (internal tooth) 25b that meshes with the planetary gear 23 is formed on the inside. Has been. Further, the outer peripheral portion of the internal gear 25 is formed with a fitting protrusion 25c that protrudes in the radial direction and can be fitted into each fitting recess 7b.

  The internal gear 25 is moved in the axial direction by an external operation as will be described later, and the fitting projection 25c is engaged with and disengaged from the fitting recess 7b on the spool side, so that the internal gear 25 is in an integrally rotated state / detached state with the spool 7. Although switched, a guide surface 7c inclined toward the fitting recess 7b is formed on the outer end surface of the protrusion 7a so that the fitting protrusion 25c can be easily fitted into the fitting recess 7b (see FIG. 8).

  The electric reel for fishing according to the present embodiment is configured so that the winding operation of the spool 7 can be performed not only by the drive motor 10 but also by a handle 29 that is rotatably mounted on the reel body (right side plate side). On the right side plate side, a manual take-up drive mechanism 30 for transmitting the rotation operation of the handle 29 to the drive of the spool 7 is arranged. On the right side plate side, a clutch mechanism 60 is arranged so that the spool 7 can freely rotate when the fishing line is released.

  Hereinafter, the manual winding drive mechanism 30 and the clutch mechanism 60 will be described with reference to FIGS. 2 to 6.

  The manual winding drive mechanism 30 is rotatably mounted between the right side plate and the right frame, and a handle shaft 31 having a handle 29 mounted on the protruding end side, and a drive gear rotatably mounted on the handle shaft 31. 32 and a pinion gear 33 that is rotatably attached to an extension portion of the drive shaft 6 on the right side plate side, is movable in the axial direction, and meshes with the drive gear 32.

  A ratchet gear 35 having a reverse rotation preventing function is attached to the base end portion of the handle shaft 31, and the handle shaft 31 is moved in the direction of winding the fishing line by engaging a locking claw 37 attached to the right frame. It is configured to be able to rotate only. A well-known drag mechanism 40 is provided between the handle shaft 31 and the drive gear 32 so that a desired drag force can be applied to the spool 7 when a fishing line is fed from the spool 7 during fishing. ing.

  A cylindrical portion 33a is integrally formed at the spool side end of the pinion gear 33, and a hole 25e formed in the central protrusion 25d of the internal gear 25 is rotatably inserted into the outer peripheral portion thereof. The internal gear 25 is retained and retained. That is, the internal gear 25 and the pinion gear 33 can move integrally in the axial direction and can rotate relative to each other. Further, a carrier 24 that rotatably supports the planetary gear is fitted to the inner peripheral portion of the cylindrical portion 33a of the pinion gear 33. When the pinion gear 33 is moved to the spool side and both are fitted, Is configured to be integrally rotatable. The carrier 24 is inserted through the drive shaft 6 so as to be rotatable.

  The clutch mechanism 60 is configured to move the spool 7 in a driving force transmission state (clutch ON) / free rotation state (clutch OFF) by moving the pinion gear 33 together with the precursor internal gear 25 in the axial direction. Specifically, as shown in FIGS. 5 and 6, the clutch mechanism 60 includes a clutch lever 61 that is rotatably held with respect to the reel body, and rotates the clutch lever 61 in the direction of arrow D in FIG. 5. A clutch plate 62 that slides in the direction of arrow S when operated is provided. The clutch plate 62 is formed with a pair of cam surfaces 63, and when the clutch plate 62 slides in the direction of arrow S, the cam surfaces guide the pair of guide rods 65 extending in the direction of the drive shaft 6. Thus, the arm piece 66 constantly biased toward the spool side can be engaged. Note that a positioning holding spring (not shown) is attached to the clutch plate 62, and the urging force of the positioning holding spring causes the clutch plate 62 to be in the state shown in FIG. 5 (clutch ON state) and FIG. The positioning is maintained in the state shown in (Clutch OFF state).

  A circumferential groove 33b is formed on the outer peripheral surface of the pinion gear 33 so that the arm piece 66 is fitted, and the arm piece 66 is disposed on the axial handle side via the clutch lever 61 and the clutch plate 62. When moved, the pinion gear 33 is moved as shown in FIG. 4 so that the internal gear 25 is detached from the spool 7. When the pinion gear 33 is moved to the spool side by the return operation of the clutch mechanism 60, the fitting protrusion 25c formed on the internal gear 25 is guided to the guide surface 7c formed on the annular protrusion 7a of the spool. As a result, the internal gear 25 is fitted into the fitting recess 7 b, so that the internal gear 25 can rotate integrally with the spool 7.

Next, the operation of the above-described fishing electric reel will be described.
When a fishing line winding operation is performed by the drive motor 10, the rotational driving force of the drive motor 10 is transmitted to the drive shaft 6 via the motor power transmission mechanism 15 and the input drive gear 17. When the drive shaft 6 is rotationally driven, the spool 7 is rotationally driven in the fishing line winding direction via the power transmission mechanism 20. Specifically, the rotational driving force of the drive shaft 6 is transmitted to the spool 7 through the sun gear 22, the planetary gear 23 and the internal gear 25. In this case, the carrier 24 that rotatably supports the planetary gear 23 is not revolved because the pinion gear 33 that rotates integrally with the carrier 24 is in a reverse rotation-preventing state by the ratchet gear 35, and the rotational drive of the sun gear 22 is It is transmitted to the spool 7 via the planetary gear 23 and the internal gear 25. Further, the handle 29 is not rotated by the ratchet gear 35 having the above-described reverse rotation preventing function.

  When the fishing line winding operation is performed by the handle 29, the rotational driving force of the handle 29 is transmitted to the pinion gear 33 via the manual winding driving mechanism 30. When the pinion gear 33 is rotationally driven, the carrier 24 also rotates integrally, so that the spool 7 is rotationally driven via the planetary gear 23 and the internal gear 25 supported by the carrier 24. In this case, when the carrier 24 revolves, the sun gear 22 and the drive shaft 6 try to rotate, but the rotation is prevented by the one-way clutch 14 attached to the right drive shaft 13b of the drive motor 10. ing. That is, the sun gear 22 does not rotate, and the planetary gear 23 revolves around the sun gear 22 to transmit power.

  Next, when the clutch lever 61 is rotated in the direction of arrow D in FIG. 5 to release the fishing line, the pinion gear 33 is in the state shown in FIG. 3 via the clutch mechanism 60 described above. To the state shown in FIG. Since the internal gear 25 is prevented from coming off and can be moved integrally with the pinion gear 33, the internal gear 25 is also moved integrally to the handle side, as shown in FIG. The spool 7 is completely detached from the internal gear 25 and the fishing line is released.

  According to the above-described configuration, when the spool 7 is in a freely rotatable state (clutch mechanism OFF state) to release the fishing line, the internal gear 25 that can rotate integrally with the spool 7 is detached from the spool 7. It becomes. That is, in the spool free state, the spool 7 is completely separated from the power transmission mechanism 20 via the internal gear 25 and is simply supported by the drive shaft 6 by the pair of bearings 8. A load such as a frictional force accompanying the meshing of the gear is not applied. As a result, when releasing the fishing line, the spool 7 can be rotated without any resistance, and the spool-free performance is improved.

  Further, in this embodiment, since the fishing line can be wound up not only by the winding of the fishing line by the drive motor 10 but also by manual operation by the handle 29, the operability can be improved and the pinion gear 33 by the clutch lever 61 mounted on the outside can be improved. Switching to the spool free state can be performed easily and reliably by the axial movement. In transmitting the driving force to the spool 7, the power transmission system by the drive motor 10 and the power transmission system by the handle 29 can be easily configured, so that the rotational friction resistance can be reduced and the winding efficiency can be reduced. There will be no decline.

  Further, in the configuration described above, the motor power transmission mechanism 15 for transmitting power from the drive motor 10 to the spool 7 is distributed to the left side plate, and the power transmission mechanism 20 and the manual winding drive mechanism 30 are distributed to the right side plate. Thus, the balance of the reel body can be improved without the weight being deviated, thereby improving the fishing operability. Further, since the power transmission system is distributed and arranged between the left and right side plates and the power transmission system is not centrally arranged on one side plate side, the assembling property and the maintenance property are not deteriorated.

  Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and can be variously modified as follows, for example.

  The present invention only needs to be configured so that the internal gear meshing with the planet gear with respect to the spool can be separated at the time of spool-free rotation, and other configurations are as described in the above embodiment. There is no limit. For example, as a means for detaching the internal gear 25 from the spool 7, in the above-described embodiment, the pinion gear is held by the pinion gear so as to be detached via the pinion gear 33 by the operation of the clutch lever. You may provide the operation member which removes directly. Further, the configuration for fitting and releasing the spool 7 and the internal gear 25, for example, the shape and number of the fitting recesses and fitting protrusions described above, is not limited to the illustrated embodiment, and various modifications are possible. Is possible.

  Further, in the above-described embodiment, the power transmission system by the drive motor and the power transmission system by the handle are distributed to the both side plates of the reel body, but the present invention is not limited to such a configuration. . Further, regarding the return mechanism for returning the clutch from OFF to ON, in addition to the clutch lever 61, a rotation operation of the handle 29 in the direction of winding the fishing line, a reverse drive of the drive motor 10, or another drive source is used. It may be performed.
