DETAILED DESCRIPTION
[0041] Hereinafter, embodiments of a fishing electric reel according to the present disclosure will be described with reference to the drawings. In the following description, terms “front and rear”, “left and right”, and “up and down” are based on directions illustrated in
[0042] As illustrated in
[0043] The left and right frames 2 and 2 are portions forming a skeleton of the reel body 1, and are integrated into the left and right via a post. A reel leg 2a to be mounted on a reel seat of a fishing rod not illustrated in the drawings is provided in the lower post. The left and right frames 2 and 2 are formed of, for example, a metal material such as an aluminum alloy or a magnesium alloy.
[0044] A spool 5 around which a fishing line is wound is rotatably supported between the left and right frames 2 and 2. In front of the spool 5, the electric motor 6 is supported by the left and right frames 2 and 2.
[0045] The electric motor 6 comprises a drive shaft (not illustrated in the drawings) extending toward the left and right frames 2 and 2. A driving deceleration mechanism that decelerates a rotational driving force of the electric motor 6 and transmits the rotational driving force to the side of the spool 5 is connected to the drive shaft extending to the side of the left frame 2. In addition, a returning deceleration mechanism 6a that decelerates the rotational driving force of the electric motor 6 and transmits the rotational driving force to a second return mechanism 40 to be described later is connected to the drive shaft extending to the side of the right frame 2.
[0046] The left and right side plates 3 and 3 are portions gripped and held by a hand of a fisherman (portions which the hand of the fisherman contacts). The left and right side plates 3 and 3 are integrally formed individually and mounted on the left and right frames 2 and 2, respectively.
[0047] The right side plate 3 is provided with a handle shaft 7 to which a manual handle is attached. The spool 5 is rotationally driven in a fishing line winding direction via a driving force transmission mechanism by the driving force by the winding operation of the manual handle and the rotational driving force of the electric motor 6. The driving force transmission mechanism by the electric motor 6 is provided on the side of the left frame 2.
[0048] As illustrated in
[0049] As illustrated in
[0050] The pinion 12 has a fitting portion to be fitted into the spool shaft. When the pinion 12 is moved to the side of the spool 5 by the yoke 24, the pinion 12 is brought into a state where the fitting portion is fitted into the spool shaft so that the driving force of the drive gear 11 is transmitted to the spool shaft (spool 5) (driving force transmission state (fishing line windable state)). In addition, when the pinion 12 is moved to the side of the right side plate 3 by the yoke 24, the pinion 12 is brought into a state where the fitting portion disengages from the spool shaft so that the driving force of the drive gear 11 is not transmitted to the spool shaft (spool 5) (driving force interruption state (fishing line unwindable state)).
[0051] The clutch mechanism 20 comprises a clutch lever 21, a clutch frame 22, a clutch operating member 23, and a yoke 24. The clutch lever 21 is disposed between rear ends of the left and right frames 2 and 2 behind the spool 5 so as to be operable while thumbing the spool 5. The clutch lever 21 is a member that switches the clutch mechanism 20 from the driving force transmission state to the driving force interruption state by placing a thumb and pushing down.
[0052] The clutch frame 22 is a metal member that supports the clutch lever 21. The clutch frame 22 is fitted into a fitting recess 23b (see
[0053] The clutch operating member 23 is an annular rotator rotatable about the spool shaft (pinion shaft). The clutch operating member 23 is formed of a material having high strength and excellent wear resistance, for example, polyacetal (POM).
[0054] The clutch operating member 23 has a pair of cams 23k and 23k (see
[0055] As illustrated in
[0056] The clutch operating member 23 is elastically divided into the driving force transmission state, which is a clutch-on position, and the driving force interruption state, which is a clutch-off position, by a dividing spring member 28 interposed between the clutch operating member and the right frame 2. As the dividing spring member 28, a torsion spring is used.
[0057] The yoke 24 is a member that moves in a left-right direction along the pinion shaft in conjunction with the rotation operation of the clutch operating member 23. The yoke 24 has a pair of arms 24a and 24a that is fitted into a circumferential groove (not illustrated in the drawings) of the pinion 12 over approximately 180° and extends in a radial direction. The arms 24a and 24a of the yoke 24 are held by support pins 25 and 25 protruding from the right frame 2, and the yoke 24 is constantly biased toward the clutch operating member 23 by a spring member (not illustrated in the drawings) disposed on each of the support pins 25 and 25.
[0058] As described above, the first return mechanism 30 is a handle operation return mechanism that causes the clutch mechanism 20 to return to the driving force transmission state using the rotational driving force of the handle (handle shaft 7).
[0059] The first return mechanism 30 comprises a ratchet 31 and a first kick member 32 as a handle interlocking kick member. The ratchet 31 is fixed to the handle shaft 7 to prevent rotation, and rotates integrally with the handle shaft 7.
[0060] The first kick member 32 is disposed on the side surface of the right frame 2 below the pinion 12 (pinion shaft) in side view, and has a substantially rectangular plate shape. The first kick member 32 has a long hole 32a through which one support pin 25 is inserted, a rectangular restriction hole 32b through which a restriction projection 33 provided on the side surface of the right frame 2 is inserted, and an engagement portion 32c which engages with the ratchet 31. A coil spring 34 (see
[0061] In the driving force transmission state illustrated in
[0062] On the other hand, when the first kick member 32 is switched from the driving force transmission state to the driving force interruption state, the engagement portion 32c moves into a rotational trajectory of the ratchet 31 as illustrated in
[0063] As described above, the second return mechanism 40 is a mechanism that causes the clutch mechanism 20 to return to the driving force transmission state using the rotational driving force of the electric motor 6.
[0064] As illustrated in
[0065] As illustrated in
[0066] When the clutch mechanism 20 is in the driving force interruption state, the detection unit 61 detects this. A position sensor 66 that detects the position of the clutch operating member 23 is connected to the detection unit 61. When a detection signal is input from the position sensor 66, the detection unit 61 detects that the clutch mechanism 20 is in the driving force interruption state, and outputs the detection signal to the driving control unit 65. The position sensor 66 can include, for example, a magnetic sensor provided on the side of the right frame 2 and a magnet provided on the side of the clutch operating member 23.
[0067] The calculation unit 62 calculates a rotation speed of the spool 5 associated with feeding of the fishing line and calculates a feeding amount of the fishing line. A rotation detection sensor 67 that detects the rotation of the spool 5 is connected to the calculation unit 62. The calculation unit 62 calculates the rotation speed of the spool 5 based on a rotation signal of the spool 5 input from the rotation detection sensor 67, and outputs a calculated value to the rotation speed determination unit 63. In addition, the calculation unit 62 calculates the feeding amount of the fishing line based on the calculated rotation speed of the spool 5, and outputs a calculated value to the feeding amount determination unit 64.
[0068] The rotation speed determination unit 63 determines whether or not the value of the rotation speed of the spool 5 calculated by the calculation unit 62 satisfies a predetermined condition set in advance. When it is determined that the value of the rotation speed of the spool 5 satisfies the predetermined condition set in advance, the rotation speed determination unit 63 outputs a determination result to the driving control unit 65. Note that the predetermined condition at the rotation speed of the spool 5 can be appropriately set by selecting a function included
[0069] The feeding amount determination unit 64 determines whether or not the feeding amount of the fishing line calculated by the calculation unit 62 has reached a preset feeding amount of the fishing line. When it is determined that a calculated value of the feeding amount of the fishing line has reached the preset feeding amount of the fishing line, the feeding amount determination unit 64 outputs a determination result to the driving control unit 65. Note that the setting of the feeding amount of the fishing line (for example, setting for stopping the rotation of the spool 5 and stopping a fishing tackle at a predetermined shelf (water depth) and the like) can be appropriately performed by selecting a function provided in the counter case 4 (see
[0070] The driving control unit 65 controls driving of the electric motor 6 in a forward rotation direction or a reverse rotation direction. When it is determined by the detection unit 61 that the clutch mechanism 20 is in the driving force interruption state and it is determined by the rotation speed determination unit 63 that the rotation speed of the spool 5 satisfies the predetermined condition, or when it is determined by the feeding amount determination unit 64 that the feeding amount of the fishing line has reached the preset feeding amount of the fishing line, the driving control unit 65 controls driving of the electric motor 6 in the reverse rotation direction. That is, the driving control unit 65 has a return control function of returning the clutch mechanism 20 from the driving force interruption state to the driving force transmission state, in addition to the normal winding control.
[0071] Next, each component of the second return mechanism 40 will be described in detail.
[0072] As illustrated in
[0073] The engagement gear 42 meshes with the returning gear 41, and receives the rotational driving force of the returning gear 41 to push the second kick member 43 downward (return from the driving force interruption state to the driving force transmission state). The second kick member 43 is a member for returning the clutch operating member 23 brought into the driving force interruption state to the driving force transmission state. The second kick member 43 is configured to engage with/disengage from the engagement gear 42 by rotating in conjunction with the rotation of the clutch operating member 23. The second kick member 43 is retained by a fixing plate 50 for fixing the handle shaft 7 to the right frame 2. The second kick member 43 is formed of a stainless steel material having strength and excellent wear resistance.
[0074] As illustrated in
[0075] As illustrated in
[0076] As illustrated in
[0077] As illustrated in
[0078] As illustrated in
[0079] A support hole 432 through which a rotation support shaft 23d (see
[0080] As illustrated in
[0081] On the other hand, a holding protrusion portion 23f that holds the second kick member 43 in an upright posture (a posture in which the abutting portion 434 faces directly upward) is formed at an upper front portion of the front end 23c. The holding protrusion portion 23f protrudes toward the right side of the front end 23c, and abuts on the rear portion of the engagement protrusion portion 433 of the second kick member 43 to hold the posture of the second kick member 43.
[0082] A locking hole 23g is formed in a rear portion of the front end 23c. A rear end of the spring member 29 connected to the second kick member 43 is locked to the locking hole 23g. The rear end of the spring member 29 is inserted into the locking hole 23g from the right side, and is covered with an upper portion 52a of the rear portion 52 of the fixing plate 50 from the right side to be retained.
[0083] The spring member 29 functions as a dividing spring that elastically divides the engagement/disengagement of the second kick member 43 with respect to the engagement gear 42. In the present embodiment, a torsion spring is used as the spring member 29. In the driving force transmission state of the clutch mechanism 20, the second kick member 43 is divided and held in a non-engagement state in which the engagement protrusion portion 433 abuts on the holding protrusion portion 23f, by the spring member 29. In addition, in the driving force interruption state of the clutch mechanism 20, the second kick member 43 is divided and held in an engagement state in which the second kick member 43 abuts on the claw portion 426 of the engagement gear 42 and can engage with the engagement claw 429, by the spring member 29.
[0084] As described above, the fixing plate 50 mainly has two functions of a function of fixing the handle shaft 7 to the right frame 2 and a function of retaining the second kick member 43. The fixing plate 50 covers a part of the front side of the clutch operating member 23, and also has a function of holding the front side of the clutch operating member 23. Similarly to the second kick member 43, the fixing plate 50 is formed of a stainless steel material having strength and excellent wear resistance.
[0085] As illustrated in
[0086] Here, the handle shaft 7 is provided with a one-way clutch (not illustrated in the drawings) and a known drag mechanism 7a illustrated in
[0087] As illustrated in
[0088] As illustrated in
[0089] An attachment portion 54 to which the front end of the coil spring 34 (see
[0090] As illustrated in
[0091] Next, a positional relation between the guide protrusion portion 436 of the second kick member 43 and each edge portion of the guide hole 55 will be described with reference to
[0092] As illustrated in
[0093] As illustrated in
[0094] Then, when the clutch lever 21 is continuously pushed down, as illustrated in
[0095] Thereafter, when the clutch lever 21 is further pushed down, the clutch mechanism 20 is brought into the driving force interruption state as illustrated in
[0096] Here, the second kick member 43 is configured to rotate toward the engagement gear 42 while moving upward along with the rotation of the clutch operating member 23. As a result, when the engagement protrusion portion 433 abuts on the large diameter portion 428 of the engagement gear 42, the engagement protrusion portion comes into contact with the outer peripheral surface of the large diameter portion 428 while sliding in the upward direction.
[0097] Next, an operation at the time of returning from the driving force interruption state to the driving force transmission state will be described. When the electric motor 6 is driven in the reverse rotation by the driving control of the control unit 60 in the driving force interruption state, the engagement gear 42 rotates in the counterclockwise direction via the returning gear 41. Then, as illustrated in
[0098] Next, an operation in a case where the engagement claw 429 is in a positional relation of interfering with the engagement protrusion portion 433 at the time of sliding when the engagement protrusion portion 433 abuts on the large diameter portion 428 will be described with reference to
[0099] As illustrated in
[0100] According to the present embodiment described above, the second kick member 43 is rotatably supported by the right frame 2, and rotates in conjunction with the clutch operating member 23 to engage with/disengage from the engagement gear 42. Therefore, it is possible to increase a degree of freedom of the layout of the components and to prevent an increase in size of the reel body 1, as compared with a conventional configuration in which the returning member engages/disengages by linear sliding movement.
[0101] In addition, since the engagement gear 42 and the second kick member 43 can be provided between the spool shaft and the motor shaft with high space efficiency, the degree of freedom of the layout of the components can be increased, and the reel body 1 can be prevented from increasing in size.
[0102] Further, the engagement claw 429 is movable in the direction opposite to the rotation direction of the engagement gear 42 against the biasing force of the spring member 425. Therefore, even if the second kick member 43 interferes with the engagement claw 429 and is engaged to push the engagement claw 429 in the direction opposite to the rotation direction of the engagement gear 42 when the second kick member 43 is engaged, the engagement claw 429 is pushed by the second kick member 43 and flexibly moves in the opposite direction. As a result, an engagement state between the second kick member 43 and the engagement claw 429 is favorably maintained. Therefore, the clutch mechanism 20 can be quickly returned from the driving force interruption state to the driving force transmission state, and the responsiveness of the return mechanism is excellent.
[0103] In addition, even if the second kick member 43 interferes with the engagement claw 429 at the time of engagement of the second kick member 43, the engagement state is maintained favorably. Therefore, it is not necessary to manage the stop position of the engagement claw 429 toward the next return, and it is not necessary to install a sensor or the like for detecting the stop position of the engagement claw 429 and provide a control unit for adjusting the position of the engagement claw 429. Therefore, it is possible to realize cost reduction while preventing an increase in size of the reel body 1.
[0104] In addition, since the clutch mechanism 20 brought into the driving force interruption state by the rotation operation of the handle can be returned to the driving force transmission state by the first return mechanism 30, it is possible to obtain the fishing electric reel 100 which is easy to use and excellent in fishing operability.
[0105] Further, the control unit 60 is provided. As a result, when the clutch mechanism 20 is in the driving force interruption state and the rotation speed of the spool 5 satisfies a predetermined condition, or when the feeding amount of the fishing line reaches a preset feeding amount of the fishing line, the clutch mechanism 20 brought into the driving force interruption state can be automatically returned to the driving force transmission state. Therefore, it is possible to obtain the fishing electric reel 100 which is easy to use and excellent in fishing operability.
[0106] The embodiment according to the present disclosure has been described above. The present disclosure is not limited to the embodiment described above, and various modifications can be made.
[0107] For example, in the above embodiment, the engagement gear 42 and the second kick member 43 are disposed in the upper region of the right frame 2 between the spool shaft and the motor shaft. However, the present disclosure is not limited thereto, and the engagement gear 42 and the second kick member 43 may be disposed in the lower region of the right frame 2 between the spool shaft and the motor shaft. Further, the engagement gear 42 and the second kick member 43 may be disposed in a region overlapping the drive gear 11 or the like of the handle shaft 7.
[0108] In the above embodiment, the restriction portion is constituted using the guide hole 55 provided in the fixing plate 50. However, the present disclosure is not limited thereto, and the second kick member 43 may be guided using the edge portion of the fixing plate 50 or the like. Further, the fixing plate 50 is constituted by one plate, but may be constituted by combining a plurality of plates.
[0109] Further, the second kick member 43 is not limited to being disposed between the right frame 2 and the fixing plate 50, and may be disposed at a position away from the fixing plate 50.
[0110] Further, the fixing plate 50 is configured to retain the dividing spring member 28. However, the present disclosure is not limited thereto, and the dividing spring member 28 may be exposed to reduce the size.
