Description

  The present invention relates to an electric fishing reel that includes a drive motor that rotationally drives a spool that is rotatably supported by a reel body, and that winds and drives the spool by rotating a manual handle provided on one side of the reel body. .

  Usually, an electric fishing reel is configured to transmit the power of a drive motor provided in a reel body to a spool via a speed reduction mechanism including a planetary gear mechanism. In general, a clutch mechanism is provided in the power transmission path to switch the spool between a fishing line winding state and a fishing line releasing state (spool free state). In addition, the reel body is provided with a manual handle so that the spool can be wound and driven not only by electric drive by a drive motor but also by manual operation. It is transmitted to the spool via a clutch mechanism provided in the power transmission path.

  By the way, in the electric fishing reel, as described above, since the speed reduction mechanism including the planetary gear is interposed in the power transmission path of the spool, even if the clutch mechanism is switched to the fishing line release state (spool free state) (clutch OFF), some gears such as planetary gears rotate together with the spool, causing rotational frictional resistance due to the meshing of the gears, resulting in inferior free performance and the problem that the mechanism cannot be delivered quickly. It was.

Therefore, in order to solve such a problem, Patent Document 1 discloses that a drive connection mechanism of a drive motor is interposed in series in a drive connection mechanism from a manual handle to a spool, and the connection between the manual handle connection mechanism and the spool is performed. An electric fishing reel is disclosed that is cut off to reduce rotational frictional resistance of the spool.
JP 2002-145

  The clutch mechanism for an electric fishing reel disclosed in Patent Document 1 described above operates a switching member (clutch lever) provided on the reel body, thereby rotating a power transmission gear provided on the spool shaft. Configured to move in the direction. That is, a non-circular cross-section engaging portion is formed on the spool side of the power transmission gear, and the power transmission gear is slid in the axial direction by operating the switching member, whereby the spool or spool The engaging portion provided on the integral spool shaft is engaged with and disengaged from the engaging portion of the power transmission gear to switch between the power transmission state (fishing line winding state) and the power cutoff state (fishing line feeding state).

  However, the power transmission gear described above is in a state of meshing with a gear that transmits rotational driving force from the handle side (drive motor side), and the power transmission gear moves in the axial direction while the gears are meshed with each other. The power transmission gear may be damaged.

  Moreover, attaching a heavy mechanism or weight to the fishing line increases the rotational load between the meshing gears, making it difficult to switch the clutch from ON to OFF. In particular, in meshing between gears, it is desirable to use a helical gear that has a high meshing rate, good meshing performance and low meshing drive noise, but it is easy to disengage the clutch (moving the power transmission gear in the axial direction). In view of the ease of the above, a helical gear cannot be used. In this case, even if a helical gear is used, in consideration of good clutch operability, the twist angle of the tooth streak cannot be increased, and there is a limit to improving the meshing performance.

  The present invention has been made based on the above-described problems, and an object thereof is to provide an electric fishing reel capable of performing a light clutch switching operation.

  In order to achieve the above-described object, an electric fishing reel according to the present invention enables a spool around which a fishing line is wound to be wound and driven by a drive motor and a manual handle provided on the reel body, and the spool. A clutch mechanism for switching between a power transmission state and a power cut-off state is provided, and a clutch actuating member is movable in the axial direction so as to be non-rotatably fitted to the rotating body rotated by the drive motor and the manual handle, and the clutch actuating member The engaging portion formed on one side of the spool can be engaged with and disengaged from the engaging portion that rotates integrally with the spool.

  According to the above configuration, when the power transmission state is changed from the power transmission state to the power cutoff state by the clutch mechanism, the clutch actuating member that is movable in the axial direction and is non-rotatably fitted to the rotating body to which the power is transmitted is disposed in the axial direction. It moves and leaves | separates from the latching | locking part which rotates integrally with a spool. Since the clutch actuating member slides in the axial direction without a rotational load acting from the rotating body that is a power transmission portion, the clutch mechanism can be easily switched.

  In the above-described configuration, the rotating body may be configured so as to be able to transmit power from a drive motor or a manual handle, and may be configured as a gear or a rotating body around which a belt is wound. Is possible. In addition, the engaging portion where the engaging portion of the clutch actuating member is engaged / disengaged may be provided at a portion that rotates integrally with the spool, and is formed on the spool itself (for example, a side surface region of the spool), Or what was formed in the edge part of the spool axis | shaft which rotationally supports a spool should just be used.

  According to the present invention, it is possible to obtain an electric fishing reel capable of performing a simple clutch switching operation.

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

  1 to 3 show a first embodiment of an electric fishing reel according to the present invention, FIG. 1 is a plan view showing an internal structure, and FIGS. 2 and 3 are main parts of FIG. FIG. 2 is a diagram showing a power transmission state (clutch ON), and FIG. 3 is a diagram showing a power cutoff state (clutch OFF).

  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. On one side plate (right side plate 4b) side that constitutes the reel body 5, a manual handle 6 that is wound up is provided, and a fishing line is placed between the left and right frames 3a and 3b that constitute the reel body 5. A spool 7 to be wound is rotatably supported. A drive motor 8 is held between the left and right frames on the front side of the spool 7, and the spool 7 will be described later by a winding operation of the manual handle 6 and a rotational drive of the drive motor 8. It is rotationally driven in the direction of winding the fishing line through the power transmission mechanism.

  The spool 7 includes a fishing line winding body portion 7a around which a fishing line is wound, and flanges 7b and 7c for restricting the fishing line to be wound are formed at both ends thereof. The spool 7 is fixed to the spool shaft 7s, and both ends of the spool shaft 7s are supported by the frames 3a and 3b via the bearings 10 so that the spool 7 is rotatably supported between the frames. Yes. 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 an engaging portion 40a of a clutch operating member 40 of a clutch mechanism described later is engaged and disengaged. Yes. 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 concave portion, a convex portion, a concave and convex portion having a non-circular cross section. Is done.

  A rotational driving force from the manual handle 6 and the drive motor 8 is input to the spool 7 via a power transmission mechanism 12. In this case, the power transmission mechanism 12 includes a speed reduction mechanism 15 that decelerates the rotational drive of the drive motor 8 and a clutch mechanism 18 that switches power transmission in the power transmission mechanism 12 between a power transmission state and a power cutoff state. ing. Hereinafter, the configuration of the power transmission mechanism 12, the speed reduction mechanism 15, and the clutch mechanism 18 will be described.

  The power transmission mechanism 12 of the present embodiment is centrally installed on the right frame 4b side of the reel body 4, and includes a handle shaft 6a that rotatably supports the manual handle 6, and a drive gear that is attached to the handle shaft 6a. 6 b, a connecting gear 20 that meshes with the drive gear 6 b and is connected to the speed reduction mechanism 15, and an intermediate gear 22 that is interposed between the speed reduction mechanism 15 and the clutch mechanism 18.

  The speed reduction mechanism 15 is configured to decelerate the rotational driving force of the drive motor 8 by a planetary gear mechanism arranged in parallel, and the first sun gear 30 and the first sun gear 30 arranged in parallel to the drive shaft 8 a of the drive motor 8. The two sun gears 31 are provided with a first planetary gear 32 and a second planetary gear 33 that mesh with each other. 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. The planetary gears 32 and 33 are meshed with internal teeth 35 a formed on the output rotating body 35, and the first carrier 32 a that supports the first planetary gear 32 is connected and fixed to the second sun gear 31. Yes. A second carrier 33 a that supports the second planetary gear 33 is connected and fixed to the connecting gear 20.

  The handle shaft 6a is provided with a reverse rotation prevention mechanism 6c so as to prevent the manual handle 6 from rotating in an interlocked manner when the drive motor 8 is driven to rotate. In addition, although the reverse rotation prevention mechanism 6c of this embodiment is configured as a reverse rotation prevention ratchet attached to the handle shaft 6a, it may be configured by a one-way clutch. A one-way clutch is provided on the left-side plate-side protruding portion of the drive shaft 8a of the drive motor 8 so that the manual handle 6 does not rotate when the manual handle 6 is wound and power is transmitted to the spool 7 side. 8d is installed.

  The rotational driving force of the output rotator 35 constituting the speed reduction mechanism 15 is transmitted to the input rotator 39 associated with the clutch mechanism 18. In this embodiment, the rotational driving force between the two is rotated. Transmission is performed via a belt 50 for power transmission. That is, grooves 35e and 39e are formed on the outer peripheral surfaces of the output rotator 35 and the input rotator 39, respectively, and the belt 50 is wound around these portions to transmit power.

  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 has a shaft-like clutch operating member 40 supported so as to be movable along the axial direction. An operating plate 42 that engages with the clutch operating member 40, a clutch plate 43 that engages with the operating plate 42 and moves the clutch operating member 40 in the axial direction, and an operation lever (clutch lever) that rotationally drives the clutch plate 43 45). A non-circular outer peripheral portion formed on one side of the clutch operating member 40 is non-rotatably fitted to the non-circular peripheral portion inside the input rotator 39.

  On the spool side of the clutch actuating member 40, an engaging portion 40a that fits into a non-circular cross-section engaging portion 7h formed on the spool shaft 7s is formed. The engaging portion 40a and the engaging portion 7h can be engaged and disengaged and have a non-circular cross-sectional fitting relationship as described above. When the both are fitted, the clutch actuating member 40 is driven to rotate so that the spool 7 Rotates integrally with the spool shaft 7s.

  The operating plate 42 is attached to an intermediate portion of the clutch operating member 40 and constantly urges the clutch operating member 40 toward the spool. In this state, as shown in FIG. The fitting portion 40a is engaged with the engaging portion 7h of the spool shaft 7s to enter a power transmission state (clutch ON). When the operation lever 45 is turned, the eccentric protrusion 45b of the operating body 45a that rotates integrally with the operation lever 45 is engaged with the engagement long hole 43b formed at the end of the clutch plate 43, and the clutch plate. 43 is slid to the axial center side of the clutch operating member 40, and the cam member 43a provided on the surface pushes up the operating plate 42 against the urging force, and slides the clutch operating member 40 toward the right side plate. In this state, the engaging portion 40a of the clutch operating member 40 is disengaged from the locking portion 7h, and the power transmission is cut off as shown in FIG. 3 (clutch OFF). The return from the clutch OFF state to the clutch ON state is performed by a winding operation of the manual handle 6 or a rotation operation of the operation lever 45 by a known return mechanism.

  Next, the power transmission path of the driving force of the manual handle 6 and the drive motor 8 by the power transmission mechanism 12 will be described with reference to FIGS.

FIG. 4 is a diagram showing a power transmission path when the manual handle 6 is rotated, and is a schematic diagram showing a planetary gear mechanism on the side of the drive motor that outputs a rotational driving force.
When the manual handle 6 is wound up, the driving gear 6b is rotated in the clockwise direction in FIG. 4, and this rotational driving force rotates the connecting gear 20 in the counterclockwise direction to counteract the second carrier 33a. Rotate clockwise. At this time, the second sun gear 31 is rotationally driven in the counterclockwise direction, and accordingly, the first carrier 32a is also rotationally driven in the counterclockwise direction. When the first carrier 32a rotates in the counterclockwise direction, the first sun gear 30 also tries to rotate in the counterclockwise direction. However, the first sun gear 30a is rotated by the one-way clutch 8d attached to the drive shaft 8a of the drive motor 8. The gear 30 cannot rotate in the counterclockwise direction, and as a result, the first planetary gear 32 rotates while revolving around the first sun gear 30 in the counterclockwise direction. As a result, the output rotating body 35 is rotationally driven in the counterclockwise direction while being decelerated by each first planetary gear 32.

  The rotation of the output rotator 35 in the counterclockwise direction rotates the input rotator 39 in the counterclockwise direction via the belt 50, and the clutch 7 is prevented from rotating around the input rotator 39. It is rotationally driven through the member 40 in the direction of winding the fishing line.

FIG. 5 is a diagram illustrating a power transmission path when the drive motor 8 is rotated, and is a schematic diagram illustrating a planetary gear mechanism on the manual handle side where a rotational driving force is output.
When the drive motor 8 is rotationally driven, the first sun gear 30 is rotationally driven in the clockwise direction in FIG. 5, and the first carrier 32a is rotationally driven in the clockwise direction by this rotational driving force. At this time, the second sun gear 31 is also rotated in the clockwise direction, and the second carrier 33a is also driven to rotate in the clockwise direction, and the second carrier 33a is driven via the connecting gear 20. The reverse rotation preventing mechanism 6b attached to the gear 6b cannot be rotated in the clockwise direction. As a result, the second planetary gear 33 rotates in the counterclockwise direction. Thus, the output rotating body 35 is rotationally driven in the counterclockwise direction while being decelerated by the rotation of each second planetary gear 33.

  Then, the rotation of the output rotator 35 in the counterclockwise direction rotates the input rotator 39 in the counterclockwise direction via the belt 50 as in the case of the manual handle 6 described above, and the spool 7 rotates the input rotation. It is rotationally driven in the direction of winding the fishing line through a clutch operating member 40 that is prevented from rotating around the body 39.

  As described above, the clutch actuating member 40 is independently rotated in the axial direction with respect to the input rotating body 39 to which the rotational driving force is input by the winding operation of the manual handle 6 and the rotational driving of the driving motor 8. By engaging the stopper, the clutch can be easily engaged and disengaged without any trouble. In other words, even when a heavy mechanism or weight is attached and a large tension acts on the fishing line, and a load is applied to the clutch engaging portion that winds and drives the spool 7, a light clutch disengagement operation can be performed. Further, in the present embodiment, power transmission to the spool 7 is performed not by the meshing relationship between the gears but by the belt 50, and in particular, noise due to gear meshing during driving of the drive motor 8 can be reduced and silenced. It becomes possible.

  6 to 8 are views showing a second embodiment of the present invention. FIG. 6 is a plan view showing the internal structure, and FIGS. 7 and 8 are enlarged views of the main part of FIG. FIG. 7 is a diagram showing a power transmission state (clutch ON), and FIG. 8 is a diagram showing a power cutoff state (clutch OFF).

  In the present embodiment, the rotational driving force is transmitted from the output rotator 35 to the input rotator 39 in the above-described embodiment by gear engagement. That is, external teeth 35b are formed on the outer peripheral surface of the output rotator 35, and the input rotator 39 is configured as a gear. An intermediate gear 22 is interposed between the output rotator 35 and the input rotator (gear) 39, so that the output rotator and the input rotator are rotationally driven in the same direction.

  Further, the spool 7 of the present embodiment is formed in a substantially cylindrical shape, and a hollow portion 7d is formed inside the fishing line winding body portion 7a around which the fishing line is wound. In this case, the hollow portion 7d is a space in which the spool shaft 7s that is rotatably supported between the left and right frames 3a and 3b is not disposed as in the embodiment shown in FIG. Free spool performance is improved by reducing the weight of the spool. In addition, you may utilize this cavity part 7d as a space which installs electrical components, such as a power supply unit and a board | substrate, like embodiment mentioned later.

  Further, on both side portions (side end surfaces) of the spool 7, bearing mounting portions 7e and 7f projecting in the axial direction are formed. The bearing mounting portions 7e and 7f may be formed integrally with the spool, or may be configured separately and integrated with the spool. Bearings 10a and 10b.

  Further, a locking portion 7h is formed on one side portion (the end surface on the right side plate side) of the spool 7 so that the engaging portion 40a of the clutch operating member 40 is engaged and disengaged. The locking portion 7h is formed on the radially inner side of the bearing mounting portion 7f, engages with the engaging portion 40a of the clutch operating member 40, and rotates the spool 7 integrally with the rotation of the clutch operating member 40. It is like that. 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 as in the above-described embodiment, for example, a concave portion or a convex portion having a non-circular cross section. It is comprised by an uneven part.

  As described above, both ends of the spool 7 are rotatably supported between the left and right frames 3a and 3b, which are reel bodies, without mounting a spool shaft at the center thereof.

  According to the configuration described above, the clutch operating member 40 is non-rotatably fitted in the gear 39 that is an input rotating body that is rotationally driven by the drive motor 8 and the manual handle 6 so as to be movable in the axial direction. Therefore, while maintaining the meshed state of the gears (intermediate gear 22, gear 39), the spool 7 can be switched between the power transmission state and the power cut-off state, and the gear tooth portion is damaged. There is nothing. Further, since the clutch actuating member is moved in the axial direction while maintaining the meshing state of the gear, it is possible to use a helical gear with good meshing performance. In such a configuration, the helical gear can be easily operated while maintaining good meshing performance by increasing the twist angle of the helical gear teeth.

  Further, in the configuration of the present embodiment, since the power transmission unit including the spool shaft, the support unit, and the like are not installed inside the spool 7, the rotating spool can be reduced in weight, and the free rotation of the spool 7 can be reduced. It becomes possible to improve. In addition, this makes it possible to shorten the length of the reel body 5 in the spool axis direction, and to reduce the size and weight as a whole. Furthermore, in the above-described configuration, it is possible to increase the size of the engaging portion 40a of the clutch operating member 40 and the engaging portion 7h of the spool 7, thereby improving the strength and durability of the power transmission portion to be engaged and disengaged. It becomes possible to do.

  FIG. 9 is a view showing a third embodiment of the present invention, and is a plan view showing an internal structure.

  Since the hollow portion 7d is formed inside the fishing line winding body portion 7a of the spool 7 as in the second embodiment described above, the power supply unit and the substrate are formed in this portion (the region 60 indicated by hatching). An electrical component such as the above may be installed.

  According to such a configuration, it is not necessary to centrally dispose electrical components between the frame and the side plate, and it is possible to disperse, so that the reel body can be reduced in size and the electrical connection portion and the like can be achieved. It becomes possible to suppress the occurrence of failure.

  As described above, the embodiments of the present invention have been described. However, in the present invention, the clutch operating member in the clutch mechanism is moved while maintaining the power transmission state of the power transmission system (including the meshing state of the gears). The power transmission mechanism, the speed reduction mechanism, the clutch mechanism, and the arrangement thereof may be appropriately modified as long as the power transmission mechanism, the speed reduction mechanism, and the clutch mechanism are configured as described above. In the above-described configuration, the clutch operating member 40 may be configured to rotate by driving the drive motor 8 and rotating the manual handle 6 and moving in the axial direction by an external switching operation. It is possible to appropriately deform such as forming a portion and sliding the outer periphery of the rotating body. Moreover, the latching | locking part 7h by which the engaging part 40a of the clutch operation member 40 is engaged / disengaged should just be provided in the part rotated integrally with a spool. Furthermore, the output rotator 35 and the input rotator 39 only need to be configured to transmit power. As described above, the power transmission by the meshing of the gears, the power transmission by the belt, and the combination thereof. You may do it.

  In addition to the above-described fishing electric reel, the present invention is also applicable to a dual-bearing type reel in which the spool is rotatably supported between both side plates and the spool is wound up by a handle winding operation. Is possible. In other words, the conventional clutch mechanism in the dual-bearing type reel has an operation plate fitted to the outer peripheral surface of the pinion gear in a state where the pinion gear is engaged with a drive gear that is mounted on the handle shaft and is rotationally driven by a rotation operation of the handle. The pinion gear is configured to slide in the axial direction. For this reason, it is difficult to use a helical gear for the drive gear and the pinion gear in consideration of the operability of the clutch disengagement. However, as in the above-described embodiment, the clutch operating member that is slidable in the axial direction is used. By engaging the pinion gear on the outer periphery to prevent rotation, the clutch operating member can be slid in the axial direction while maintaining the meshed state of the gears. That is, according to such a double-bearing type reel, it is possible to use a helical gear with good meshing performance while maintaining light operability of clutch disengagement.
