Description

The present invention relates to a fishing reel whose braking force can be adjusted and a braking device that can be used therefor.

Conventionally, when throwing an object to be thrown such as a lure, fishing line, weight, fishing hook, etc. to a long distance using both bearing reels, a braking device for braking the spool is provided to prevent backlash (thread entanglement) at the time of throwing. There are many. With such a braking device, when the braking force is optimized, it can be thrown to the farthest distance, but if the braking force is too large, the flight distance will be reduced, and on the other hand, if the braking force is too small, backlash will occur. Will be invited. The optimization of braking force can vary depending on the type of fishing tackle used, such as the weight and air resistance of the lure to be thrown, the type of fishing line, and the characteristics of the rod. It may also change depending on the throwing method of the user and the weather conditions such as wind. The user needs to adjust the braking force by trial and error at the time of use.

As such a fishing reel, for example, in Patent Document 1, a spool braking device for a double-bearing reel that brakes a spool rotatably mounted on a reel body, and brakes the spool in an electrically controllable manner. The spool braking unit, the first braking force setting unit that sets the first braking force, the tension setting unit that sets the reference tension, the tension detection unit that detects the tension acting on the fishing thread, and the first braking force. As a reference, the second braking force setting unit that sets the second braking force with increased braking force, and the spool braking unit is controlled by the first braking force at the start of braking, and then detected by the tension detection unit. A spool braking device for both bearing reels including a spool control unit that controls the spool braking unit by the second braking force when the detected tension becomes equal to or lower than the reference tension is disclosed.

In such a braking device, after the braking force to the spool is set to the first braking force, the tension is estimated by detecting the rotational acceleration of the spool, and when the estimated tension becomes equal to or less than the reference value, the first control is performed. By changing to a second braking force that is larger than the power, for example, when using a light mechanism or in the case of a headwind, the spool is braked with a strong braking force, and the fishing conditions change to some extent. However, there is no need to reset the strength of the braking force.

Generally, when throwing a lure or the like, the user properly uses various throwing methods depending on various situations such as surrounding obstacles, weather conditions, and the distance to the target throwing target point. If the throwing method is different, the flight trajectory of the lure or the like will change, so the optimum brake setting value may also change. In addition, there are various types of lures and the like used depending on the situation, and the optimum brake setting value may change depending on the weight and air resistance.

Hereinafter, embodiments of the present invention will be specifically described with reference to the accompanying drawings. Structures common to a plurality of drawings are designated by the same reference numeral throughout the plurality of drawings. It should be noted that each drawing is not always drawn to the correct scale for convenience of explanation.

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

As shown in the figure, the fishing reel 10 winds the fishing line 31 around the spool 11, switches between a state in which the fishing line 31 can be released from the spool 11 and a state in which the fishing line 31 cannot be released, and applies a tension equal to or higher than a set value to the fishing line 31. The spool 11 slips (drag function), the above threshold tension can be set, and the braking force for preventing backlash during casting can be adjusted.

The spool 11 can wind the fishing line 31, and when it is rotated in the forward direction by the operation unit 14, the fishing line 31 can be wound. The clutch 12 can select connection / disengagement of power transmission with the operation unit 14. In the connected state, winding by the operation unit 14 is possible. In the open state, the spool 11 can be freely rotated in the forward and reverse directions, and the fishing line 31 can be discharged. Further, the drag device 13 can idle the spool 11 when a load equal to or higher than the tension set on the fishing line 31 is applied. Further, a known oscillator device may be provided in which the fishing line 31 is evenly wound around the spool 11 by reciprocating the line guide for guiding the fishing line in conjunction with the rotation of the spool 11.

The operation unit 14 is configured as, for example, a handle, and can transmit the rotation operation of the user to the spool 11 by a transmission mechanism such as a gear, and rotate the spool 11 in the forward direction. The operation unit 14 may be a combination of an operation member such as a lever and a power source such as a motor. Further, the braking unit (spool braking unit) 15 can exert a braking force on the spool. This suppresses the occurrence of backlash during casting. This braking force can be set by the braking force control unit (spool braking force control unit) 16.

Next, the braking unit (spool braking unit) 15 will be described in more detail with reference to FIG. The braking portion (spool braking portion) 15 is an annular rotating body-shaped vortex current generating plate 51 made of a non-magnetic conductor integrally attached to the spool 11 and an annular shape that is arranged so as to face each other with a minute gap in the radial direction and alternates in the circumferential direction. A fixed magnet 52 and a rotating magnet 53 in which the north and south poles are magnetized, a motor 54 for rotating the rotating magnet 53 (not shown), and a position sensor 56 (not shown) for detecting the position of the rotating magnet 53. It is composed of.

The outer peripheral portion of the fixed magnet 52 is divided into six equal parts and magnetized alternately with N poles and S poles. Further, the inner peripheral portion of the rotating magnet 53 is divided into six equal parts, and the N pole and the S pole are alternately magnetized. The magnetic field generated 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, an eddy current is generated in the eddy current generating plate 51, and a braking force corresponding to the rotation speed acts.

By rotating the rotating magnet 53 by the motor 54 and the gear train 55, the magnetic field acting on the eddy current generating plate 51 can be changed. Thereby, the braking force can be set to a predetermined amount. That is, when the rotating magnet 53 and the fixed magnet 52 face each other with the same poles, the magnetic field applied to the eddy current generating plate 51 becomes weak and the braking force becomes weak. When the rotating magnet 53 and the fixed magnet 52 face each other with different poles, the magnetic field applied to the eddy current generating plate 51 becomes stronger and the braking force becomes stronger.

The magnet position sensor 56 is a sensor that detects the position of the rotating magnet 53, and is composed of a known position sensor such as a magnetic sensor or an electric resistance type.

The braking force control unit (spool braking force control unit) 16 feedback-controls the motor 54 by passing a necessary current through the motor 54 while observing the value of the magnet position sensor 56. As a result, a predetermined braking force can be applied to the spool 11. In this way, the braking force applied to the spool 11 can be changed over time by the braking force control unit (spool braking force control unit) setting unit 16.

The eddy current generating plate 51 may be formed of a part of the spool 11. Further, as is known, the eddy current generating plate 51 changes the magnetic field by relatively moving with respect to the spool 11 by the action of centrifugal force according to the rotation speed of the spool 11, so as to have a predetermined braking force characteristic. You may do it.

Further, the braking unit (spool braking unit) 15 described above is not limited to the method using the eddy current as described above, and the same effect can be realized as long as the braking force can be adjusted over time by a microcomputer. .. Other methods of the braking device include a method of generating a regenerative brake between the permanent magnet attached to the spool and the coil provided in the reel body, and a method of changing the contact force with the friction plate attached to the spool by an electromagnetic actuator or the like. There is a method using a contact brake to make the brake, and the method is not limited to a specific method.

Next, FIG. 3 is a diagram showing an electrical configuration of the reel 10. The fishing reel 10 has a detection unit (sensor) 19 for detecting various operations by the user and the state of the reel. The detection result is sent to the calculation unit 17, and after performing calculation processing as necessary and temporarily storing the detection result in the storage unit 18, the braking force control unit 16 is instructed to perform the target braking force. The detection unit 19 includes the following. Some may be omitted due to restrictions such as cost and size.

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 may be attached to a part of the member on which the clutch operates.

Next, the azimuth detection unit 192 can detect the direction in which the reel 10 is facing by detecting the direction of the geomagnetism. The acceleration detection unit 193 detects the translational acceleration of the reel 10. This can be achieved by using a conventionally known acceleration sensor such as a piezo resistance method or a capacitance detection method. Further, the angular velocity detection unit 194 detects the angular velocity (speed in the rotation direction) of the reel 10. This can be realized by using a conventionally known gyro sensor, such as a method of detecting a frequency change of a vibrated piezoelectric element.

By using a sensor called a 9-axis motion sensor that detects the direction, acceleration, and angular velocity of each of the three orthogonal axes, the orientation detection unit 192, the acceleration detection unit 193, and the angular velocity detection unit 194 can be used. Hereinafter, these are referred to as motion sensors. By calculating these detection results, it is possible to acquire the posture of the fishing rod to which the reel 10 is attached and the operation by the user.

For example, the acceleration detection unit 193 can calculate the elevation angle of the reel by measuring each component of the gravitational acceleration in the stationary state of the reel. Further, by integrating the values of the angular velocity sensors of each axis with time from that state, the time change of the elevation angle of the reel can be calculated.

The output value of each sensor may include an error, and the error may be integrated by time integration or the like. Therefore, it is advisable to deterministically estimate the position and orientation of the reel from a plurality of output values of the motion sensor by using a known calculation method such as a Kalman filter. In the present embodiment, for example, the posture of the reel can be calculated from the output value of the motion sensor as needed.

By calculating the value obtained by the detection unit 19 by the calculation unit 17 as necessary, other states and operation information of the reel 10 can also be acquired and calculated. More specifically, it is possible to obtain the set values of the winding amount of the fishing line, the releaseable state, and the braking force. In addition, the take-up speed, which is these time derivative values, can also be calculated.

In addition to the form built in the reel body, the motion sensor may be arranged on a rod to which the reel 10 is attached and sent to the arithmetic unit 16 by using wired communication or wireless communication. Further, the calculation unit 16 and the storage unit 18 may be arranged on a rod or an external device such as a mobile phone, in addition to the form built in the reel body.

It is configured to include a part 16.

According to the braking device according to the embodiment of the present invention, it is possible to provide a braking device capable of changing the braking force in response to a change in conditions that cannot be detected by a change in the rotational acceleration of the spool.

In the braking device 1 according to the embodiment of the present invention, the spool braking force control unit 16 determines the throwing method based on the output of the motion sensor 19, and controls the spool 11 according to the determination result of the throwing method. It is configured to change the power.

In this way, according to the braking device 1 according to the embodiment of the present invention, even when the user changes the throwing method, the braking device is set according to the throwing method without any special operation. Is possible.

In the braking device 1 according to the embodiment of the present invention, the spool braking force control unit 16 calculates the operation of the fishing reel 10 from the output of the motion sensor 19, and pattern-matches the feature points of the operation. Is configured to determine the throwing method.

In this way, according to the braking device 1 according to the embodiment of the present invention, it is possible to change the braking force to the spool 11 according to the determination result of the throwing method.

In the braking device 1 according to the embodiment of the present invention, the spool braking force control unit 15 detects the transfer speed before throwing by the motion sensor 19, and changes the braking force to the spool 11 according to the speed. It is configured to do.

The fishing reel according to the embodiment of the present invention is configured to have any of the above braking devices.

According to the fishing reel according to the embodiment of the present invention, there is provided a fishing reel having a braking device capable of changing the braking force in response to a change in conditions that cannot be detected by a change in the rotational acceleration of the spool. Is possible.

The fishing rod according to the embodiment of the present invention is provided with a fishing reel and is configured to have any of the above braking devices.

According to the fishing rod according to the embodiment of the present invention, a fishing rod provided with a fishing reel having a braking device capable of changing the braking force in response to a change in conditions that cannot be detected by a change in the rotational acceleration of the spool. It will be possible to provide.

Next, a method of throwing a thrown object such as a lure will be described using a general fishing reel including the main 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 handle rotation axis direction is defined as the Y axis, and the direction orthogonal to the X axis and the Y axis is defined as the Z axis.

When throwing a lure or the like using the fishing reel 10, several throwing methods are used depending on the surrounding conditions and the throwing distance. A typical example will be described below.

First, a throwing method called overhead casting will be described with reference to FIG. 5 (A). This throwing method is often used when a long throwing distance is desired. The change in the angle between the X axis and the direction of gravity at this time is shown in FIG. 5 (B). Here, the angle is set so that the angle is 0 ° directly below, 90 ° in the throwing direction, 180 ° directly above, and 270 ° directly behind when viewed from the user. Further, in the illustrated example, the rotation start time of the spool is set to t = 0. In this way, the change in elevation angle during the overhead cast is once directed to the rear (about 225 °), then vigorously crosses overhead (180 °), and moves forward (about 135 °) with the start of spool rotation.

Next, a throwing method called a side cast will be described with reference to FIG. 6 (A). This throwing method is often used when the throwing target needs to be thrown with a low trajectory, such as when aiming at the water surface under the ground covered with obstacles such as standing trees and grass, or when there is a strong headwind. The change in the angle between the X axis and the direction of gravity at this time is shown in FIG. 6 (B). In this way, in the side cast, the direction of the rod is kept around 90 ° with respect to the direction of gravity from beginning to end.

Further, a throwing method called pitching will be described with reference to FIG. 7 (A). This throwing method is often used when it is desired to accurately aim at a shorter distance than the side cast or when it is desired to reduce the sound of water landing. The change in the angle between the X axis and the direction of gravity at this time is shown in FIG. 7 (B). In this way, in pitching, throwing is performed while the rod pointing slightly downward is projected forward.

Even if the initial velocity of the spool is the same, if the throwing method is changed, the ejection point and ejection angle of the lure etc. will change, and the trajectory will also change, so the optimum brake setting may differ. For example, in the overhead cast, the injection point is generally higher than that in the side cast, so even if the initial velocity of the spool is the same, the overhead cast tends to have a longer flight time and a longer flight distance. Therefore, it is more effective to set the brakes for long-time flight during overhead casting.

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

As described above, the posture such as the elevation angle of the fishing reel 10 can be calculated from the output value of the motion sensor 19. Then, the start of throwing can be detected by detecting the start of rotation of the spool 11 or detecting that the value of the angular velocity becomes a predetermined value or more.

In the braking device according to the embodiment of the present invention, when the start of throwing is detected, the throwing method is estimated from the posture information of the fishing reel 10 before and after the start of throwing. For example, in the above-mentioned three throwing methods, in the case of overhead casting, the angle formed by the rod (X-axis) and the direction of gravity is around 180 °. Therefore, when the maximum value of the angle formed by the fishing rod and the direction of gravity is a predetermined value or more (for example, 150 °) or more, it can be determined that the overhead cast is performed.

Next, in the case of side cast, there is no big change in the angle between the fishing rod and the direction of gravity, and it is between 75 ° and 150 ° from beginning to end. Therefore, if the angle between the rod and gravity is within this range, it can be determined to be a side cast.

In the case of pitching, the angle between the fishing rod and the direction of gravity fluctuates within a range of about 45 ° to 135 °. Therefore, when the minimum value of the angle formed by the fishing rod and the gravity direction is not more than a predetermined value (for example, 70 °), it can be determined that the pitching is performed.

In addition to the above examples, the user may use various throwing methods. When classifying more finely including them, a large number of teacher data may be prepared in advance for each throwing method, and pattern matching may be performed by a machine learning method such as a neural network. In that case as well, the reel attitude information such as the elevation angle may be calculated from each output value of the motion sensor, and pattern matching may be performed by a known algorithm using the feature points such as the maximum value and the differential value. In the above example, pattern matching was performed using only the angle formed by the X-axis and the gravity direction in order to simplify the explanation and reduce the amount of calculation. More accurate discrimination can be made by using other information that can be calculated from the sensor.

After determining the throwing method, set the braking device according to the throwing method. For example, when it is determined to be an overhead cast, the braking force immediately after throwing is set to strong, and the braking force is set to medium 1500 ms after throwing. If it is determined to be a side cast, the braking force immediately after throwing is set to strong, and the braking force is set to medium 1000 ms after throwing. Further, when it is determined to be pitching, the braking force immediately after throwing is set to medium, and the braking force is set to weak 500 ms after throwing.

As a result, even when the throwing method is changed, the user can set the braking device according to the throwing method without performing a special operation. As for the braking force setting value for each throwing method, it is advisable to find the optimum value in advance by trial throwing under the same conditions.

Further, in another embodiment of the present invention, the speed at which the fishing rod is swung may be measured from the output of the angular velocity sensor and the time change rate of the acceleration sensor or the orientation sensor, and the braking force may be changed according to the value. .. For example, if the maximum value of the angular velocity before throwing is equal to or higher than the first predetermined value, the setting of the braking device is set to the first braking force. Further, if the value is south of the first predetermined value and equal to or greater than the second predetermined value, the setting of the braking device is set to the second braking force. Further, if it is equal to or less than the second predetermined value, the third braking force is used.

As the distance to the target throwing target point increases, the user needs to swing the fishing rod more strongly, and the optimum setting value of the braking device at that time also changes. Further, even if the target throwing target point and the weight of the thrown object are the same, if the air resistance is different, it is necessary to change the strength of the swinging speed of the rod, and the optimum setting value of the braking device in each is also different.

By setting the braking force according to the speed at which the rod is swung as described above, special operations can be performed even if the distance to the throwing target point aimed at by the user or the thrown object is changed. It is possible to set the braking force of the braking device according to the throwing.

Both of the above two examples may be performed. That is, the throwing method and its strength may be detected and the setting of the braking device may be changed for each.

Next, with reference to FIG. 8, a method of setting a braking force in the braking device according to the embodiment of the present invention will be described. As shown in the figure, the vertical axis is determined by ranking the speed of swinging the fishing rod into three types according to the maximum value of the angular velocity sensor immediately before throwing, and the horizontal axis is determined by guessing the throwing method. The setting of the braking force of the braking device can be determined according to the matrix of the combination.

By doing so, even if the throwing method and its strength are changed, the user can set the braking device according to the throwing method without performing a special operation. As for the braking force setting value for each throwing method, it is advisable to find the optimum value in advance.

As described above, according to the present invention, by using the output value of the motion sensor for the condition change that cannot be detected by the change in the rotational acceleration of the spool, the braking force of the braking device is optimized without any special operation by the user. It is possible to set it.
