Description

Electric reel {ELECTRICAL FISHING REEL}

The present invention relates to electric reels.

Conventionally, as an electric reel for fishing, the rotation amount or rotation angle of the handle, which is suitable for operations such as attracting fish, is detected, and the detected rotation amount or rotation angle is fed back to the motor to control the motor. A reel with a motor assist function that assists the operation of the handle by power is known (for example, see Patent Document 1).

Japanese Patent Publication Patent No. 5919077

In an electric reel as shown in Patent Document 1, if a sensor for detecting handle rotation is attached to the main body of the reel body on the handle side that accommodates the clutch return mechanism, the length of the drive gear shaft increases. Therefore, there was a problem that the handle side body bulged toward the handle side and became large. If the handle side body is enlarged, the position of the handle will move away from the fixed position of the fishing rod, and the weight balance between the left and right sides of both bearing reels may be lost, which may reduce operability, so there is room for improvement in that respect.

In addition, regarding the position of the detected part such as the magnet detected by the sensor, it is necessary to arrange it so that rotation resolution can be secured since it rotates together with the drive gear shaft.

The present invention was made in consideration of such circumstances, and its purpose is to efficiently arrange the sensor and the detection target within the reel body on the handle side, suppress the reel body from being enlarged in the axial direction, and improve operability. The goal is to provide an electric reel that can do this.

Additionally, by attaching the detected portion to a member that rotates together with the drive gear shaft, the axial length of the reel body on the handle side can be suppressed to a small size. As a result, the entire reel can be miniaturized compared to a conventional electric reel, and the loss of operability due to loss of weight balance between the left and right sides of the electric reel can be prevented.

Furthermore, in this aspect 1, regarding the position of the detected part detected by the sensor, it can be arranged in a position that rotates together with the drive gear shaft in the axial direction at a position closer to the frame than the drive gear.

A state in which rotation from the handle 20 can be transmitted to the spool 30 is a clutch-on state, and a state in which rotation from the handle 20 is blocked is a clutch-off state. In the clutch-off state, the spool 30 is in a free rotation state, and the fishing line can be released.

＜Rotational transmission mechanism＞

Next, the rotation transmission mechanism 40 will be described in detail based on FIG. 3 .

The rotation transmission mechanism 40 includes a function to regulate torque when torque is transmitted in the opposite direction from the spool 30 to the handle 20 side. The rotation transmission mechanism 40 includes a drive gear shaft 41 with a handle 20 fixed to the shaft distal end 41b (second end), and a drive gear connected to the shaft proximal end 41a of the drive gear shaft 41. (42) and a pinion gear (not shown) engaged with the drive gear (42).

The drive gear shaft 41 is disposed within the right reel body 10A, that is, on the right side of the right side plate 11A. The drive gear shaft 41 extends in the left and right directions, penetrates the top surface 121 of the right cover 12 in the axial direction, and has a star drag 3 or A handle 20 is disposed. The drive gear shaft 41 corresponds to the handle shaft and is arranged in the left-right direction, that is, parallel to the axial direction of the spool 30. The drive gear shaft 41 is rotatably inserted into a cylindrical body 44 fixed to the right cover 12 at the center portion in the axial direction via a roller clutch 60.

Here, the longitudinal direction (direction extending left and right) of the drive gear shaft 41 is hereinafter referred to as the axial direction.

On the drive gear shaft 41, a retainer 61, a stopper gear 62, a drive gear 42, and a roller clutch 60 are arranged in that order from the shaft base end 41a to the shaft tip 41b. there is. Furthermore, on the side of the shaft distal end 41b rather than the drive gear 42, a drag washer or a plate washer made of a plurality of thin metal plates is arranged in a state where they are overlapped in the axial direction, and are disposed on the drive gear shaft 41. It is installed so that it cannot rotate. In the rotation transmission mechanism 40, rotational power is transmitted from the handle 20 to the spool 30 by the friction force of the drag washer, and drag performance is exhibited.

In the electric reel 1 configured in this way, the order of handle 20, drive gear shaft 41, drag washer, drive gear 42, pinion gear not shown, and spool 30 (clutch on state) Power from the handle 20 is transmitted. In addition, when the fishing line is pulled strongly in the discharge direction, a force exceeding the compression force (friction force) of the drag is applied to the drive gear 42, that is, the spool 30, pinion gear, and drive gear 42 are pulled. Forces act in that order. At this time, slip occurs between the drive gear 42, the drag washer, and the plate washer, and the fishing line is released.

The shaft proximal end 41a of the drive gear shaft 41 is mounted on the convex portion 112 of the right fixing plate 11D. The drive gear shaft 41 has a shaft base end 41a rotatably supported in the shaft support recess 111 of the right fixing plate 11D through a bearing 63, and a shaft tip 41b with a roller clutch ( It is rotatably supported on the top surface 121 of the right cover 12 through 60). The shaft tip 41b is connected to the handle 20. The outer diameter of the shaft proximal end 41a is larger than the outer diameter of shaft portions other than the shaft proximal end 41a in the drive gear shaft 41.

The drive gear 42 has a gear on its outer circumference, and this gear meshes with the pinion gear. The drive gear 42 is fixed to the handle side rather than the retainer 61 on the shaft tip 41b side of the drive gear shaft 41, and is connected to rotate integrally with the rotation of the drive gear shaft 41. It is done. The pinion gear not only constitutes the rotation transmission mechanism 40 but also functions as the clutch mechanism 50. With this configuration, the drive gear 42 transmits torque generated by rotation of the handle 20 to the spool 30 in the clutch-on state.

Here, a bearing 63 that rotatably supports the shaft base end 41a of the drive gear shaft 41 is fitted into the shaft support recess 111 formed in the right fixing plate 11D. At the center of the cross section of the shaft base end 41a of the drive gear shaft 41, a hole portion 41c with a circular cross section is formed that opens toward the bottom of the shaft support concave portion 111. At the center of the concave bottom of the shaft support concave portion 111, a convex portion 112 extends to the right. The hole portion 41c of the drive gear shaft 41 is engaged with the convex portion 112.

The roller clutch 60 is inserted into a through hole 121a provided in the top surface 121 of the right cover 12 and regulates rotation of the drive gear shaft 41 in one direction. The roller clutch 60 regulates rotation of the drive gear shaft 41 in a direction opposite to the line winding direction. The roller clutch 60 has an outer ring and a plurality of rolling elements. The outer ring is non-rotatably mounted in the through hole 121a of the right cover 12. The outer ring has a cam surface, not shown, on its inner circumferential surface. The plurality of rolling elements are cylindrical and are arranged between the inner peripheral surface of the outer ring and the outer peripheral surface of the drive gear shaft 41. The plurality of rolling elements allow rotation of the drive gear shaft 41 in the line winding direction. In addition, the roller clutch 60 may have an inner ring fixed to the outer peripheral surface of the drive gear shaft 41.

The retainer 61 regulates movement of the drive gear shaft 41 in the axial direction with respect to the right reel body 10A. The retainer 61 is fixed to the right fixing plate 11D with screws or the like.

The stopper gear 62 (gear portion, switching portion, one-way clutch) is disposed between the drive gear 42 and the retainer 61 at the axial base end 41a of the drive gear shaft 41, and moves in the axial direction. It is installed in a state where movement from side to side of the handle 20 is regulated. The stopper gear 62 is fixed in a non-rotatable state with respect to the drive gear shaft 41 and is rotatable together with the drive gear shaft 41. A clutch detent and a clutch cam (not shown) of the clutch mechanism 50 are disposed at approximately the same position as the stopper gear 62 when viewed from the side in a direction perpendicular to the axial direction of the drive gear shaft 41.

4 and 5, a plurality of convex engagement teeth 621 are provided on the outer peripheral edge of the stopper gear 62 at intervals in the circumferential direction. The clutch pawl of the clutch mechanism 50 can be engaged with the plurality of engagement teeth 621. The stopper gear 62 switches the clutch mechanism 50 from the disconnected state to the transmitted state based on the rotation of the drive gear shaft 41. The stopper gear 62 is non-rotatably fixed to the drive gear shaft 41 and rotates together with the drive gear shaft 41. The rotation of the stopper gear 62 in one direction is regulated by the clutch detent of the clutch mechanism 50. Therefore, the stopper gear 62 regulates rotation of the drive gear shaft 41 in one direction. In this way, the stopper gear 62 of this embodiment also has a function as a return gear.

3 and 5, a plurality of magnets 71 (detected portions) are provided on one end surface 62a facing the right fixing plate 11D (right plate 11A) of the stopper gear 62. A plurality of them (six in this case) are installed at intervals in the circumferential direction around the axis of the drive gear shaft 41. The positions of the plurality of magnets 71 are such that the radial distance from the axial center of the drive gear shaft 41 is almost identical to the distance from the axial center of the sensor 72 described later, and the stopper gear ( The magnet 71 rotating together with 62) is in a position where it can face the sensor 72 in the axial direction.

The magnet 71 rotates with the rotation of the stopper gear 62, that is, the rotation of the drive gear shaft 41. The magnet 71 is disposed between the drive gear 42 and the right fixing plate 11D of the frame 11 in the axial direction, and is rotatable with the drive gear shaft 41. The magnet 71 is detected by a sensor 72 installed at a position opposite to the stopper gear 62.

The sensor 72 is installed at a position corresponding to the magnet 71 on the right fixing plate 11D side of the stopper gear 62. The sensor 72 is disposed in a concave portion between the shaft support concave portion 111 and the outer cylinder 113 in the right fixing plate 11D of the frame 11. The sensor 72 detects the rotation angle of the magnet 71 in a predetermined unit time, that is, detects the rotation of the drive gear shaft 41. And, according to the detection result detected by the sensor 72, the output of the motor 15 is controlled by a control unit (not shown).

Next, the operation of the electric reel 1 configured as described above will be explained in detail based on the drawings.

In the electric reel 1 according to the present embodiment, as shown in FIG. 3, when a sensor 72 for detecting the rotation of the drive gear shaft 41 is provided in the right reel body 10A, A member that arranges the magnet 71 and the sensor 72 between the drive gear 42 and the right fixing plate 11D of the frame 11, and rotates the magnet 71 together with the drive gear shaft 41. By attaching it to the , the axial length of the right reel body 10A can be kept small. As a result, the entire reel can be miniaturized compared to a conventional electric reel, and the loss of operability due to loss of weight balance between the left and right sides of the electric reel 1 can be prevented.

Additionally, in this embodiment, regarding the position of the magnet 71 detected by the sensor 72, it is positioned together with the drive gear shaft 41 at a position on the right fixing plate 11D side of the drive gear 42 in the axial direction. It can be placed in a rotating area. Therefore, the magnet 71 can be placed in a position where rotation resolution can be secured without being interfered with by the drive gear 42.

Additionally, in the electric reel 1 of this embodiment, a plurality of magnets 71 are installed at intervals in the circumferential direction of the drive gear shaft 41. Therefore, by installing a plurality of magnets 71 at intervals in the circumferential direction of the drive gear shaft 41, the detection accuracy of the rotation amount or rotation angle detected by the sensor 72 can be further increased.

In addition, in this embodiment, a stopper gear 62 is provided on the drive gear shaft 41 between the drive gear 42 and the right fixing plate 11D and rotates together with the drive gear shaft 41. there is. A plurality of magnets 71 are installed at intervals in the circumferential direction on one end surface 62a of the stopper gear 62 facing the right fixing plate 11D. The sensor 72 is disposed on the right fixing plate 11D side of the stopper gear 62.

By this, the magnet 71 is placed on the stopper gear 62 located between the drive gear 42 and the right fixing plate 11D, and the sensor 72 is positioned on the right fixing plate 11D side rather than the gear portion. Since they are arranged in , the magnet 71 and sensor 72 can be effectively placed in the right reel body 10A. As a result, the axial length of the right reel body 10A can be more reliably reduced, and the entire reel can be miniaturized compared to a conventional electric reel.

Additionally, in this embodiment, the stopper gear 62 regulates rotation of the drive gear shaft 41 in one direction. In this way, the magnet 71 is attached to the stopper gear 62, which is located between the drive gear 42 and the right fixing plate 11D and rotates together with the drive gear shaft 41, so that the magnet 71 ) and the sensor 72 can be placed more effectively. As a result, the axial length of the right reel body 10A can be more reliably reduced, and the entire reel can be miniaturized compared to a conventional electric reel.

In addition, in this embodiment, a clutch mechanism 50 is provided to switch between a transmission state for transmitting rotation from the handle 20 to the spool 30 and a disconnection state for disconnecting rotation from the handle 20 to the spool 30. It is available. The stopper gear 62 is a switching unit that switches the clutch mechanism 50 from the disconnected state to the transmitted state based on the rotation of the drive gear shaft 41. In this way, the magnet 71 is located between the drive gear 42 and the right fixing plate 11D and is attached to the switching unit that rotates together with the drive gear shaft 41, thereby forming the magnet 71 and the sensor. (72) can be placed more effectively. As a result, the axial length of the right reel body 10A can be more reliably reduced, and the entire reel can be miniaturized compared to a conventional electric reel.

Additionally, in this embodiment, the sensor 72 is installed on the right fixing plate 11D. As a result, a relatively wide installation space for the sensor 72 can be secured on the right fixing plate 11D, so the sensor 72 can be placed at a position corresponding to the magnet 71 on the right fixing plate 11D. It gets easier. Additionally, in this case, since the sensor 72 is placed directly on the right fixing plate 11D, the axial length of the right reel body 10A can be more reliably suppressed to a smaller size.

Additionally, in this embodiment, the magnet 71 is disposed at the end of the drive gear shaft 41 on the right fixing plate 11D side. The sensor 72 is installed in an opposing portion facing the magnet 71. As a result, since the magnet 71 and the sensor 72 are arranged to face each other in the axial direction, the rotating magnet 71 can be detected by the sensor 72 to a higher degree.

Additionally, in this embodiment, the sensor 72 detects the rotation angle of the magnet 71 in a predetermined unit time. By this, the rotation angle of the magnet 71, which rotates together with the drive gear shaft 41, detected by the sensor 72, is fed back to the motor 15, and the handle 20 is driven by the power of the motor 15. ) can assist with the operation.

Additionally, in this embodiment, there is a control unit that controls the output of the motor 15 according to the detection result detected by the sensor 72. Accordingly, the output of the motor 15 is appropriately controlled by the control unit and the detection result of the magnet 71 rotating together with the drive gear shaft 41 is detected by the sensor 72, and is fed back to the motor 15. The power of the motor 15 can assist in the operation of the handle 20.

In the electric reel 1 according to the present embodiment configured as described above, the sensor 72 and the magnet 71 can be efficiently arranged within the right reel body 10A, and the reel body 10 can be enlarged in the axial direction. can be suppressed and operability can be improved.

Above, embodiments of the electric reel according to the present invention have been described, but these embodiments are presented as examples and are not intended to limit the scope of the invention. The embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention. Embodiments and modifications thereof include, for example, those that can be easily imagined by a person skilled in the art, those that are substantially the same, those that are in an equivalent range, etc.

For example, in this embodiment, the present invention is applied to an electric reel, but the present invention may be applied to fishing reels other than electric reels.

Additionally, in this embodiment, the sensor 72 is installed on the frame 11 (right fixing plate 11D), but the position of the sensor 72 is not limited to being placed on the frame 11. The idea is that the sensor 72 is disposed at a position between the drive gear 42 and the frame 11 where the magnet 71 (detected portion) can be detected.

Additionally, in this embodiment, the magnet 71 (detected portion) is installed on the stopper gear 62 that rotates together with the drive gear shaft 41, but it is not limited to this position. The point is that it is a position between the drive gear 42 and the frame 11, and any part that rotates together with the drive gear shaft 41, such as a gear part, a switching part, or a one-way clutch, is sufficient. In other words, the position of the detected part may be placed on the frame side of the return gear that rotates together with the drive gear shaft 41 instead of the stopper gear 62.

In addition, the frame that defines the axial range in which the detected portion and the sensor are arranged is not limited to the right fixing plate 11D as in this embodiment, and may be the right plate 11A.

Furthermore, in this embodiment, six magnets 71 are installed at intervals in the circumferential direction on the one end face 62a of the stopper gear 62 facing the right fixing plate 11D, but the number of magnets 71 is The arrangement interval in the circumferential direction can be appropriately set based on detection results such as the rotation angle of the detected portion for a predetermined unit time.

In addition, the positional relationship between the detected part and the sensor is also arranged at a position opposite to the axial direction of the drive gear shaft 41 in this embodiment, but is not limited to this positional relationship. In essence, as long as the positional relationship allows the detection target part to be detected by the sensor, it may be arranged to face each other in a direction intersecting the axial direction. Also, it is not limited to the fact that the detected part and the sensor are facing each other.

As another electric reel configuration, for example, a modified electric reel 1A can be adopted. In the electric reel 1A of the modified example, the magnet 71 is disposed on the axial end surface 41d of the shaft base end 41a of the drive gear shaft 41, and the sensor 72 is positioned with respect to the magnet 71. It is installed in the concave part 114 which is the opposing surface part of the opposing right fixing plate 11D. The magnet 71 of the shaft end surface 41d rotates together with the drive gear shaft 41.

In this case, even if it is difficult to attach the magnet 71 to the member that rotates together with the drive gear shaft 41, the magnet 71 is placed on the axial end surface of the drive gear shaft 41, and this magnet ( The rotation amount or rotation angle can be detected with high accuracy by the sensor 72 installed at a position on the right fixing plate 11D side opposite to 71).
