Description

[Technical field]

[0001] The present invention relates to a fishing reel with adjustable braking force and a possible braking device for use therewith. [Background technology]

[0002] Conventionally, when a dual-bearing reel is used to cast a lure, fishing line, sinker, hook, or other throwing object far away, a braking device that brakes the spool is often provided to prevent backlash (line tangling) during casting. With such a braking device, the lure can be cast the furthest when the braking force is optimized, but if the braking force is too large, the casting distance is reduced, and if the braking force is too small, backlash is caused. The optimization of the braking force can vary depending on the type of fishing gear used, such as the weight of the lure to be cast, air resistance, type of fishing line, and rod characteristics. It can also vary depending on the user's casting method and weather conditions such as wind. The user needs to adjust the braking force through trial and error when using the reel.

[0003] As an example of such a fishing reel, Patent Document 1 discloses a spool braking device for a dual-bearing reel that brakes a spool that is rotatably attached to a reel body, the spool braking device including a spool braking section that electrically controllably brakes the spool, a first braking force setting section that sets a first braking force, a tension setting section that sets a reference tension, a tension detection section that detects the tension acting on the fishing line, a second braking force setting section that sets a second braking force that is an increased braking force based on the first braking force, and a spool control section that controls the spool braking section with the first braking force when braking begins, and then controls the spool braking section with the second braking force when the detected tension detected by the tension detection section falls below the reference tension.

[0004] In this type of braking device, the braking force applied to the spool is first set to a first braking force, and then the tension is estimated by detecting the rotational acceleration of the spool. If the estimated tension falls below a reference value, the braking force is changed to a second braking force that is greater than the first braking force. As a result, for example, when a light tackle is used or there is a headwind, the spool is braked with a strong braking force, and there is no need to readjust the strength of the braking force even if the fishing conditions change to some extent.

[0005] [Patent Document 1] JP 2009-159847 A Summary of the Invention [Problem to be solved by the invention]

[0006] Generally, when a user throws a lure or the like, the user uses various throwing methods depending on various circumstances such as surrounding obstacles, weather conditions, and the distance to the intended throwing target point. Different throwing methods change the flight trajectory of the lure or the like, and therefore the optimal brake setting value may also change. In addition, there are various types of lures or the like used depending on the situation, and the optimal brake setting value may also change depending on the weight and air resistance.

[0007] However, in the configuration described in Patent Document 1, the braking force is changed in response to changes in the rotational acceleration of the spool, which causes the problem that it is difficult to respond to changes in conditions that cannot be detected by changes in the rotational acceleration of the spool, such as when the throwing method or the object thrown, such as a lure, is changed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. Elements common to multiple drawings are designated by the same reference numerals throughout the multiple drawings. Please note that the drawings are not necessarily drawn to scale for ease of explanation.

[0017] First, with reference to FIG. 1, a configuration of a fishing reel 1 according to an embodiment of the present invention will be described.

[0018] As shown in the figure, the fishing reel 10 winds a fishing line 31 onto a spool 11, switches between a state in which the fishing line 31 can be released from the spool 11 and a state in which it cannot be released, and when tension above a set value is applied to the fishing line 31, the spool 11 spins freely (drag function), and the above-mentioned threshold tension can be set and the braking force can be adjusted to prevent backlash when casting.

[0019] The spool 11 is capable of winding the fishing line 31, and when rotated forward by the operating unit 14, the fishing line 31 can be wound up. The clutch 12 can select whether to connect or disconnect the power transmission to the operating unit 14. When connected, the fishing line can be wound up by the operating unit 14. When disconnected, the spool 11 can be freely rotated forward and backward, and the fishing line 31 can be released. The drag device 13 can also cause the spool 11 to spin freely when a load greater than a set tension is applied to the fishing line 31. A known oscillator device can also be provided that reciprocates a line guide that guides the fishing line in conjunction with the rotation of the spool 11, thereby winding the fishing line 31 evenly onto the spool 11.

[0020] The operating unit 14 is configured as, for example, a handle, and can transmit a user's rotation operation to the spool 11 via a transmission mechanism such as gears, thereby rotating the spool 11 in the forward direction. The operating unit 14 may be a combination of an operating member such as a lever and a power source such as a motor. Furthermore, the braking unit (spool braking unit) 15 can apply a braking force to the spool, thereby suppressing the occurrence of backlash during casting. This braking force can be set by a braking force control unit (spool braking force control unit) 16.

[0021] Next, the braking unit (spool braking unit) 15 will be described in more detail with reference to Fig. 2. The braking unit (spool braking unit) 15 is composed of an annular rotor-shaped eddy current generating plate 51 made of a non-magnetic conductor that is attached integrally to the spool 11, a fixed magnet 52 and a rotary magnet 53 that are annular and magnetized with N and S poles alternately in the circumferential direction and arranged facing each other with a small gap in the radial direction, a motor 54 (not shown) that rotates the rotary magnet 53, and a position sensor 56 (not shown) that detects the position of the rotary magnet 53.

[0022] The outer periphery of the fixed magnet 52 is divided into six equal parts and magnetized with alternating north and south poles. The inner periphery of the rotating magnet 53 is divided into six equal parts and magnetized with alternating north and south poles. The magnetic field created by the fixed magnet 52 and the rotating magnet 53 penetrates the eddy current generating plate 51 located between them. Therefore, when the spool 11 rotates, eddy currents are generated in the eddy current generating plate 51, and a braking force according to the rotation speed is applied.

[0023] By rotating the rotary magnet 53 with the motor 54 and the gear train 55, the magnetic field acting on the eddy current generating plate 51 can be changed. This makes it possible to set the braking force to a predetermined amount. That is, when the rotary magnet 53 and the fixed magnet 52 are arranged with the same poles facing each other, the magnetic field acting on the eddy current generating plate 51 is weakened, and the braking force is weakened. When the rotary magnet 53 and the fixed magnet 52 are arranged with the opposite poles facing each other, the magnetic field acting on the eddy current generating plate 51 is strengthened, and the braking force is strengthened.

[0024] The magnet position sensor 56 is a sensor that detects the position of the rotating magnet 53, and is configured by a known position sensor such as a magnetic sensor or an electrical resistance type sensor.

[0025] The braking force control unit (spool braking force control unit) 16 performs feedback control of the motor 54 by supplying a necessary current to the motor 54 while monitoring the value of the magnet position sensor 56. This makes it possible to apply a predetermined braking force to the spool 11. In this way, the braking force control unit (spool braking force control unit) setting unit 16 makes it possible to change the braking force applied to the spool 11 over time.

[0026] The eddy current generating plate 51 may be configured as a part of the spool 11. As is well known, the eddy current generating plate 51 may be moved relative to the spool 11 by centrifugal force in response to the rotation speed of the spool 11 to change the magnetic field and provide a predetermined braking force characteristic.

[0027] Furthermore, the above-mentioned braking section (spool braking section) 15 is not limited to the above-mentioned type that utilizes eddy currents, and can achieve the same effect as long as the braking force can be adjusted over time by a microcomputer. Other types of braking devices include a type that generates a regenerative brake between a permanent magnet attached to the spool and a coil provided in the reel body, and a type that uses a contact brake that changes the contact force on a friction plate attached to the spool with an electromagnetic actuator, etc., and is not limited to a specific type.

[0028] Next, Fig. 3 is a diagram showing the electrical configuration of the reel 10. The fishing reel 10 has a detection unit (sensor) 19 that detects various operations by the user and the state of the reel. The detection results are sent to a calculation unit 17, which performs calculation processing as necessary and temporarily stores the results in a memory unit 18, and then indicates a target braking force to the braking force control unit 16. The detection unit 19 includes the following. Some of the detection units may be omitted due to limitations in cost, size, etc.

[0029] The clutch state detection unit 191 detects whether or not the fishing line 31 can be released from the reel 10. This can be achieved by detecting the connection state of the clutch 12. A limit sensor or the like can be attached to a part of the member that operates the clutch.

[0030] Next, the orientation detection unit 192 detects the direction of geomagnetism, thereby being able to detect the direction in which the reel 10 is facing. The acceleration detection unit 193 detects the acceleration in the translational direction of the reel 10. This can be achieved by using a conventionally known acceleration sensor, such as a piezoresistance type or a capacitance detection type. Furthermore, the angular velocity detection unit 194 detects the angular velocity (speed in the rotational direction) of the reel 10. This can be achieved by using a conventionally known gyro sensor, such as a type that detects frequency changes in a vibrated piezoelectric element.

[0031] In addition, by using a sensor called a 9-axis motion sensor that detects the orientation, acceleration, and angular velocity of each of three orthogonal axes, it is possible to configure the orientation detection unit 192, acceleration detection unit 193, and angular velocity detection unit 194. Hereinafter, these will be referred to as motion sensors. By calculating the results of these detections, the attitude of the fishing rod to which the reel 10 is attached and the operation by the user can be obtained.

[0032] For example, the elevation angle of the reel can be calculated by measuring each component of the gravitational acceleration when the reel is stationary using the acceleration detection unit 193. In addition, the change in the elevation angle of the reel over time can be calculated by integrating the values ​​of the angular velocity sensors of each axis from that state.

[0033] The output value of each sensor may contain an error, and the error may be accumulated by time integration or the like. Therefore, it is advisable to use a known calculation method such as a Kalman filter to probabilistically estimate the position and orientation of the reel from the multiple output values ​​of the motion sensor. In this embodiment, for example, the orientation of the reel can be calculated as necessary from the output value of the motion sensor.

[0034] By calculating the values ​​obtained by the detection unit 19 as necessary in the calculation unit 17, other status and operation information of the reel 10 can also be obtained and calculated. More specifically, the amount of fishing line wound up, the release possible state, and the braking force setting can be obtained. In addition, the winding speed, which is the time derivative of these values, can also be calculated.

[0035] The motion sensor may be built into the reel body, or may be placed on the fishing rod to which the reel 10 is attached, and may send the signal to the calculation unit 16 using wired or wireless communication. The calculation unit 16 and memory unit 18 may be built into the reel body, or may be placed on the fishing rod or an external device such as a mobile phone.

[0036] The braking device 1 of one embodiment of the present invention is a braking device 1 for a dual-bearing reel that brakes a spool 11 that is rotatably attached to the reel body, and is configured to include a spool braking unit 15 that brakes the spool 11, a motion sensor 19 that detects at least one of the acceleration, angular velocity or attitude of the dual-bearing reel, and a spool braking force control unit 16 that can change the braking force applied by the spool braking unit 15 depending on the output of the motion sensor 19 when cast.

[0037] According to the braking device of one embodiment of the present invention, it is possible to provide a braking device that can change the braking force in response to changes in conditions that cannot be detected by changes in the rotational acceleration of the spool.

[0038] In the braking device 1 of one embodiment of the present invention, the spool braking force control unit 16 is configured to determine the throwing method based on the output of the motion sensor 19, and to change the braking force applied to the spool 11 according to the result of the throwing method determination.

[0039] In this way, according to the braking device 1 of one embodiment of the present invention, even if the user changes the throwing method, the braking device can be set to match that throwing method without performing any special operations.

[0040] In the braking device 1 according to one embodiment of the present invention, the spool braking force control unit 16 is configured to calculate the movement of the fishing reel 10 from the output of the motion sensor 19, and to determine the casting method by pattern matching characteristic points of the movement.

[0041] In this way, according to the braking device 1 of the embodiment of the present invention, it is possible to change the braking force applied to the spool 11 in accordance with the result of discrimination of the throwing method.

[0042] In the braking device 1 according to one embodiment of the present invention, the spool braking force control unit 15 is configured to detect the casting speed before throwing using the motion sensor 19, and to change the braking force applied to the spool 11 according to the speed.

[0043] A fishing reel according to one embodiment of the present invention is configured to include any one of the braking devices described above.

[0044] According to a fishing reel according to one embodiment of the present invention, it is possible to provide a fishing reel having a braking device that can change the braking force in response to changes in conditions that cannot be detected by changes in the rotational acceleration of the spool.

[0045] A fishing rod according to one embodiment of the present invention includes a fishing reel and is configured to have any one of the braking devices described above.

[0046] According to a fishing rod according to one embodiment of the present invention, it is possible to provide a fishing rod equipped with a fishing reel having a braking device that can change the braking force in response to changes in conditions that cannot be detected by changes in the rotational acceleration of the spool.

[0047] Next, a method of casting a lure or other object to be cast will be described using a general fishing reel including the fishing reel 10. In the following, as shown in Fig. 4, the longitudinal direction of the fishing rod is defined as the X-axis, the direction of the handle rotation axis is defined as the Y-axis, and the direction perpendicular to the X-axis and Y-axis is defined as the Z-axis.

[0048] When casting a lure or the like using the fishing reel 10, several casting methods can be used depending on the surrounding conditions and the casting distance. Representative examples are described below.

[0049] First, a throwing method called overhead cast will be described with reference to FIG. 5(A). This throwing method is often used when it is desired to increase the throwing distance. FIG. 5(B) shows the change in the angle between the X-axis and the direction of gravity at this time. Here, the angles are set so that, as seen from the user, directly below is 0°, the throwing direction is 90°, directly above is 180°, and directly behind is 270°. In the illustrated example, the time when the spool starts to rotate is set to t=0. In this way, the change in the elevation angle during overhead cast is such that the spool first turns backward (about 225°), then vigorously passes over the head (180°), and turns forward (about 135°) as the spool starts to rotate.

[0050] Next, a throwing method called side casting will be explained with reference to Figure 6(A). This throwing method is often used when aiming at the water surface below obstacles such as trees or grass, or when it is necessary to throw the target on a low trajectory, such as when there is a strong headwind. Figure 6(B) shows the change in the angle between the X-axis and the direction of gravity at this time. Thus, in side casting, the direction of the rod is kept at approximately 90° with respect to the direction of gravity throughout.

[0051] Furthermore, a throwing method called pitching will be explained with reference to Figure 7(A). This throwing method is often used when you want to accurately aim at a distance even shorter than side casting, or when you want to reduce the sound of the lure hitting the water. Figure 7(B) shows the change in the angle between the X-axis and the direction of gravity at this time. Thus, in pitching, the lure is thrown while pointing the rod slightly downward and thrusting it forward.

[0052] Even if the initial speed of the spool is the same, changing the throwing method will change the launch point and launch angle of the lure, and the trajectory, so the optimal brake setting may be different. For example, overhead casting generally has a higher launch point than side casting, so even if the initial speed of the spool is the same, overhead casting tends to have a longer flight time and a longer distance. Therefore, it is more effective to set the brakes to accommodate longer flights when casting overhead.

[0053] Next, a method for adjusting the braking force of a braking device according to one embodiment of the present invention will be described. In the braking device according to one embodiment of the present invention, the throwing method is estimated from the output value of the motion sensor from immediately before the throw, and the characteristics of the braking device are changed according to the estimation result.

[0054] As described above, the attitude of the fishing reel 10, such as the elevation angle, can be calculated from the output value of the motion sensor 19. Then, the start of casting can be detected by detecting the start of rotation of the spool 11 or by detecting that the angular velocity value is equal to or greater than a predetermined value.

[0055] In a braking device according to an embodiment of the present invention, when the start of casting is detected, the casting method is inferred from the posture information of the fishing reel 10 before and after the start of casting. For example, in the above-mentioned three casting methods, in the case of overhead casting, the angle between the rod (X-axis) and the direction of gravity fluctuates around 180°. Therefore, when the maximum value of the angle between the fishing rod and the direction of gravity is equal to or greater than a predetermined value (e.g., 150°), it can be determined that the casting method is overhead casting.

[0056] Next, in the case of a side cast, the angle between the fishing rod and the direction of gravity does not change significantly and is always between 75° and 150°. Therefore, if the angle between the fishing rod and gravity is within this range, it can be determined that it is a side cast.

[0057] In the case of pitching, the angle between the fishing rod and the direction of gravity varies within a range of about 45° to about 135°. Therefore, if the minimum value of the angle between the fishing rod and the direction of gravity is equal to or less than a predetermined value (for example, 70°), it can be determined that pitching is occurring.

[0058] In addition to the above examples, users may use various throwing methods. To classify them in more detail, a large amount of teacher data may be prepared for each throwing method in advance, and pattern matching may be performed using machine learning techniques such as neural networks. In this case, as in the above, reel attitude information such as the elevation angle is calculated from each output value of the motion sensor, and pattern matching may be performed using a known algorithm using characteristic points such as the maximum value and differential value. In the above example, pattern matching is performed using only the angle between the X-axis and the gravity direction to simplify the explanation and reduce the amount of calculation, but more accurate discrimination can be performed by using other information that can be calculated from the motion sensor, such as the attitude in the Y-axis direction or Z-axis direction and angular velocity.

[0059] After determining the throwing method, the braking device is set to a setting that matches that throwing method. For example, if it is determined to be an overhead cast, the braking force immediately after the throw is set to strong, and 1500 ms after the throw is set to medium. If it is determined to be a side cast, the braking force immediately after the throw is set to strong, and 1000 ms after the throw is set to medium. If it is determined to be a pitching, the braking force immediately after the throw is set to medium, and 500 ms after the throw is set to weak.

[0060] This allows the user to set the braking device to suit a different throwing method without performing any special operations, even if the user changes the throwing method. Note that it is advisable to find the optimal value for the braking force setting for each throwing method in advance by performing test throws under the same conditions.

[0061] In another embodiment of the present invention, the speed at which the fishing rod is swung may be measured from the output of an angular velocity sensor or the time rate of change of an acceleration sensor or a direction sensor, and the braking force may be changed depending on the measured value. For example, if the maximum value of the angular velocity before casting is equal to or greater than a first predetermined value, the braking force is set to the first braking force. If the maximum value is equal to or greater than the first predetermined value and a second predetermined value, the braking force is set to the second braking force. If the maximum value is equal to or less than the second predetermined value, the braking force is set to the third braking force.

[0062] When the user is farther away from the intended throwing target point, the user needs to swing the fishing rod harder, and the optimal setting value of the braking device at that time also changes. Even if the intended throwing target point and the weight of the throwing object are the same, if the air resistance is different, the user needs to change the strength of the swing speed of the rod, and the optimal setting value of the braking device in each case also differs.

[0063] By setting the braking force according to the speed at which the rod is swung as described above, even if the user changes the distance to the intended throwing target point or the object to be thrown, the braking force of the braking device can be set to match the throw without any special operation.

[0064] It is also possible to implement both of the above two examples. That is, the throwing method and its strength may be detected, and the settings of the braking device may be changed for each.

[0065] Next, a method for setting the braking force in a braking device according to an embodiment of the present invention will be described with reference to Fig. 8. As shown in the figure, the vertical axis is determined by classifying the fishing rod swing speed into three types according to the maximum value of the angular velocity sensor immediately before casting, the horizontal axis is determined by estimating the casting method, and the setting of the braking force of the braking device can be determined according to the matrix of the combination.

[0066] In this way, even if the user changes the throwing method and its strength, the braking device can be set to match the throwing method without performing any special operations. It is advisable to find the optimal braking force setting value for each throwing method in advance.

[0067] Thus, according to the present invention, by utilizing the output value of the motion sensor for changes in conditions that cannot be detected by changes in the rotational acceleration of the spool, it is possible to optimally set the braking force of the braking device without the user having to perform any special operations.

[0068] The dimensions, materials, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any dimensions, materials, and arrangement that can be included in the scope of the present invention. In addition, components not explicitly described in this specification can be added to the described embodiments, and some of the components described in each embodiment can be omitted.
