Abstract
Description
[Technical Field]
[0001] The present invention relates to a fishing reel speed governor, a handle device, and a fishing reel. [Background technology]
[0002] When fishing with lures or artificial baits called tairaba, the catch can vary depending on how the lure is moved, but there is a technique that can increase the catch by moving the lure at a constant speed without changing speed, thereby making the target fish less wary. However, with reels that move lures by manually turning the handle, the position of the user's hand and the angle of the handle change constantly, and the effect of the handle's own weight also changes depending on the position. As a result, it is difficult for beginners to turn the handle at a desired speed without unevenness, and it is said that practice is required.
[0003] For example, Patent Document 1 discloses a handle operation assistance device that can guide a user on the speed at which a fishing reel handle should be rotated within one rotation of the handle. The fishing reel emits an alarm at regular intervals, allowing the user to use it as a guide for rotating the reel at a constant speed. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] Japanese Patent Publication No. 2020-058248 Summary of the Invention [Problem to be solved by the invention]
[0005] However, the goal of turning the handle at a constant speed was still left up to the user, and the mechanism was no different from that of a conventional reel. Also, while it is easy to move a lure at a constant speed using a regular electric reel, electric reels require a motor and power source, which increases the weight and limits the range of use (target fish).
[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a fishing reel speed governor, a handle device, and a fishing reel that can be attached to a fishing reel and that can reduce unevenness in the speed of winding up the fishing line. [Means for solving the problem]
[0007] In order to solve the above problem, the present invention is characterized by comprising an input member that rotates integrally with the handle, an output member that rotates in accordance with the rotation of the input member and transmits power for winding in the fishing line, and a spring member that is capable of accumulating and generating a rotational restoring force equivalent to the rotation of the handle between the input member and the output member.
[0008] According to the present invention, by accumulating and generating a rotational restoring force in the spring member in response to rotation of the handle, the rotational speed of the output member can be made uniform, thereby reducing unevenness in the fishing line winding speed.
[0009] It is also preferable to provide resistance generating means for generating a resistance force corresponding to the rotation speed in a direction opposite to the direction in which the restoring force acts on the output member in the rotation direction.
[0010] According to the present invention, the rotation speed of the output member can be made more uniform.

[0012] According to the present invention, the resistance generating means can be easily configured.
[0013] It is also preferable that the resistance generating means includes a movable member that faces the output member and can change the distance between itself and the output member by operation by a user so as to change the volume of the storage space for the viscous fluid.
[0014] According to the present invention, the rotation speed of the output member can be adjusted in response to an operation by a user.
[0015] It is also preferable that one of the output member and the movable member has a resistance groove recessed in the axial direction and extending circumferentially, and the other has a resistance protrusion protruding in the axial direction, extending circumferentially, and facing the resistance groove.
[0016] According to the present invention, the contact area with the viscous fluid can be increased, thereby effectively generating resistance.
[0017] It is also preferable to provide an operating member that can switch between a state in which the input member and the output member are brought into contact to transmit power directly, and a state in which the input member and the output member are separated to transmit power indirectly via the spring member.
[0018] According to the present invention, power transmission can be changed according to the user's preference.
[0019] Preferably, the resistance generating means comprises a centrifugal brake. Preferably, the resistance generating means comprises an escapement.
[0020] According to the present invention, the resistance generating means can be easily configured.
[0021] The present invention also provides a handle device that can be attached to a fishing reel, the handle comprising the fishing reel speed governor device according to any one of claims 1 to 8 and a handle that transmits power to the input member. The present invention also provides a fishing reel comprising a reel body and the fishing reel speed governor device according to any one of claims 1 to 8 provided on the reel body. [Effects of the Invention]

[0024] [First embodiment] A fishing reel R1 according to an embodiment of the present invention will be described with reference to the drawings. In the following description, "front and back" and "up and down" refer to the directions shown in Fig. 1, and "left and right" refer to the directions shown in Fig. 2. In each embodiment, the same parts are designated by the same reference numerals, and detailed descriptions will be omitted.
[0025] First, the basic structure of the fishing reel R1 will be described. As shown in Figure 1, a fishing reel R1 comprises a reel body 1 to which a handle 3 is attached, a rotor 4 provided in front of the reel body 1 and rotated by the winding operation of the handle 3, and a spool 5 provided in front of the rotor 4 and reciprocating back and forth by the winding operation of the handle 3.
[0026] The reel body 1 comprises a body 10 having a side opening 11 that opens toward the left side, legs 12 that extend upward from the top of the body 10 and have a rod attachment portion at their tip that is attached to a fishing rod, a cover member 13 that closes the side opening 11, and a protective cover 14 attached to the rear of the body 10. The body 10 also comprises a cylindrical front body portion 10A (see Figure 2) through which the drive shaft tube 7 and spool shaft 8 pass. A rotor 4 is attached to the front end of the drive shaft tube 7, and a spool 5 is attached to the front end of the spool shaft 8.
[0027] As shown in Fig. 2, the cover member 13 has a cylindrical insertion portion 13a that is inserted into the inside of the side opening 11. A male thread is formed on the outer peripheral surface of the insertion portion 13a. The male thread is threaded into a female thread formed on the inner peripheral surface of the side opening 11. This threading unites the body 10 and the cover member 13 together.
[0028] Within the body 10, there are provided a drive gear shaft 2 extending in the left-right direction and a spool reciprocating device 60 as components for driving the drive shaft cylinder 7 and the spool shaft 8 in conjunction with the operation of the handle 3. The drive gear shaft 2 includes a drive gear 21 and a gear 22. The drive gear shaft 2 is rotatably supported by the cover member 13 and the body 10 via left and right ball bearings 15 and 16.
[0029] The spool reciprocating device 60 includes a slider 61 and an interlocking gear 62, and is configured so that the slider 61 moves in the front-to-rear direction along a guide shaft (not shown) that extends in the front-to-rear direction of the body 10. The slider 61 is fixed to the rear end of the spool shaft 8 with a fixing screw 8a, and includes a guide groove 61a that opens to the right side. The interlocking gear 62 is supported by a support member 63 provided on the right wall of the body 10, and rotates in mesh with the gear 22 of the drive gear shaft 2. The interlocking gear 62 includes an eccentric protrusion 62a that engages with the guide groove 61a of the slider 61.
[0030] As described above, when the drive gear shaft 2 and gear 22 rotate due to the reeling operation of the handle 3, the interlocking gear 62 rotates, and this rotational motion is converted into the forward and backward motion of the slider 61 via the eccentric protrusion 62a and the guide groove 61a. This causes the spool shaft 8 (spool 5) to reciprocate in the forward and backward directions.
[0031] 2 and 3, a handle device 200 will be described, which includes a handle 3 and a speed governor 100. The speed governor 100 includes an input member 101, an output member 102, a spring member 103, and a fixed cylinder 104.
[0032] The input member 101 is a shaft-shaped member that rotates integrally with the handle 3. The input member 101 includes a main body 111, a flange 112, a notch 113, and a tip 114. The main body 111 is axially shaped and is disposed along the rotation axis C from the hollow portion of the skirt 3a of the handle 3 to the inside of the fixed cylinder 104. The flange 112 protrudes in a direction perpendicular to the rotation axis C and is fixed to the handle 3 so as to be rotatable integrally with the handle 3. The notch 113 is formed by cutting out a portion of the main body 111, and is a portion to which one end of the spring member 103 is connected.
[0033] The output member 102 rotates in response to the rotation of the input member 101 and transmits the power to rotate the rotor 4 (power to reel in the fishing line). The output member 102 is installed so as to be rotatable relative to the input member 101. The output member 102 includes a base plate 121, a cylindrical storage portion 122, and a fixed cylindrical portion 123. The base plate 121 is a plate-shaped portion disposed perpendicular to the rotation axis C. A through-hole 121a is formed in the center of the base plate 121, into which the tip 114 of the input member 101 is inserted. The cylindrical storage portion 122 is a cylindrical portion extending from the base plate 121 toward the handle 3, parallel to the rotation axis C. The spring member 103 is disposed in a hollow portion formed by the base plate 121 and the cylindrical storage portion 122. The fixed cylindrical portion 123 is a cylindrical portion extending from the base plate 121 toward the cover member 13, parallel to the rotation axis C. A thread groove that screws onto the drive gear shaft 2 is formed on the inner peripheral surface of the fixed cylindrical portion 123. This allows the output member 102 and the drive gear shaft 2 to rotate synchronously. In addition, the output member 102 and the drive gear shaft 2 can be attached or detached.
[0034] A fastening member 105 is disposed inside the fixed cylinder portion 123. The fastening member 105 is a member that fastens the output member 102 to the tip end portion 114 of the input member 101.
[0035] The spring member 103 is a member capable of accumulating and generating a rotational restoring force corresponding to multiple rotations of the handle 3 between the input member 101 and the output member 102. In this embodiment, a spiral spring is used as the spring member 103, but other springs may be used. In other words, the spring member 103 is preferably a member capable of rotating the rotor 4 at a substantially constant speed. One end of the spring member 103 is connected to the notch 113 of the input member 101, and the other end is connected to the notch 122a of the cylindrical housing portion 122 of the output member 102. The spring member 103 (spiral spring) is spirally wound around the input member 101 and generates a restoring force in response to the relative rotation angle between the input member 101 and the output member 102 (hereinafter, this angle will be referred to as θ). As is generally known, the restoring force generated by a contact-type spiral spring has a region where it increases in proportion to θ and a region where it changes nonlinearly with θ.
[0036] The fixed barrel 104 is a cylindrical member disposed between the handle 3 and the lid member 13. The fixed barrel 104 includes a cylindrical portion 131, a lid portion 132, and a protruding portion 133. The cylindrical portion 131 is disposed concentrically with the rotation axis C. A convex portion 131a provided at the end of the cylindrical portion 131 on the lid member 13 side is fitted into a concave groove 13c of the lid member 13. The lid portion 132 is a plate-like portion that covers the end of the cylindrical portion 131 on the handle 3 side. A through-hole 132a is formed in the center of the lid portion 132, into which the storage cylindrical portion 122 is inserted. The protruding portion 133 is a plate-like portion that protrudes in the direction of the rotation axis C at a middle portion in the height direction of the cylindrical portion 131. A through-hole 133a is formed in the center of the protruding portion 133, into which the fixed barrel 123 is inserted.
[0037] The storage space N is formed by the space surrounded by the cylindrical portion 131, the lid portion 132, and the protruding portion 133 of the fixed cylinder 104, and the output member 102. In this embodiment, the storage space N is filled with grease, which constitutes a "resistance generating means." It is desirable for the grease to be made of a material with high viscosity to generate sufficient viscous force. If the amount of grease filled in the storage space N is large, the rotational resistance increases, causing the drive gear shaft 2 and the output member 102 to rotate relatively slowly. If the amount of grease filled is small, the rotational resistance decreases, causing the drive gear shaft 2 and the output member 102 to rotate relatively quickly. The amount of grease filled in the storage space N can be adjusted as appropriate. Instead of grease, other viscous fluids, such as gel, may be used.
[0038] Next, the effects of this embodiment will be described. When a user turns the handle 3 in one direction, the output member 102 does not rotate initially, and a restoring force is accumulated in the spring member 103. In other words, the spring member 103 is tightened via the input member 101. It is preferable to turn the handle 3 multiple times, but it is sufficient to turn it at least 90 degrees or more.
[0039] After that, the output member 102 gradually starts to rotate according to the amount of charge stored in the spring member 103. At this time, the rotation speed of the output member 102 changes depending on the amount of charge stored in the spring member 103. The rotation speed of the input member 101 does not directly depend on the rotation speed of the output member 102. Even if the rotation operation of the handle 3 is stopped, if the amount of charge stored in the spring member 103 is sufficiently large, the output member 102 continues to receive torque in the rotational direction and continues to rotate at a roughly constant speed. As the amount of charge stored in the spring member 103 decreases, the rotation of the output member 102 also slows down and eventually stops.
[0040] This reduces the change in the rotation speed of the output member 102 even if there is a change in the speed at which the user rotates the handle 3. This reduces the unevenness in the speed at which the fishing reel R1 reels in the fishing line, and increases the chances of a fish biting when using a specific fishing method, such as when using an artificial bait.
[0041] This embodiment also includes a resistance generating means for generating a resistance force corresponding to the rotation speed of the output member 102 in the direction opposite to the direction in which the restoring force acts in the rotation direction. In other words, the grease filled in the accommodation space N creates rotational resistance, making it possible to make the rotation speed of the rotor 4 more uniform. Furthermore, by adjusting the amount of grease filled, it is possible to adjust the winding speed of the fishing line. The mechanism for reducing speed unevenness and the effect of the resistance generating means will be described in detail in the second embodiment.
[0042] Furthermore, in this embodiment, the speed governor 100 can be attached and detached to an existing fishing reel. This allows customization according to the user's wishes. Furthermore, in this embodiment, the speed governor 100 is disposed outside the cover member 13, but it may also be disposed inside the cover member 13 (inside the reel body 1). Furthermore, the speed governor 100 is compatible with both right-hand and left-hand handles. Note that the handle winding direction is opposite for right-hand and left-hand handles. Therefore, the handle device for a right-hand handle and the speed governor device for a left-hand handle must be assembled so that the winding direction of the spring member 103 is opposite.
[0043] Although the resistance generating means has the above-described configuration in this embodiment, it may have another configuration. Also, the resistance generating means may be omitted.
[0044] [Second embodiment] Next, a handle device 300 according to a second embodiment of the present invention will be described with reference to Figures 4 and 5. The handle device 300 includes a handle 301, a lock lever 302, and a speed governor 400.
[0045] 5 to 7, the handle 301 is attached to the input member 411 and rotates in synchronization with the input member 411. Similar to the handle 3 of the first embodiment, the handle 301 is a member that transmits a rotational force of a user's rotational action to the rotor 4 via the input member 411, etc.
[0046] The lock lever (operating member) 302 is provided on the cover member 13 side of the handle 301. The lock lever 302 is threadedly engaged with one end of the input member 411 via a nut member 303. The lock lever 302 is provided so as to be rotatable in one direction or the other at a predetermined angle with respect to the rotation axis C.
[0047] As shown in FIGS. 5 to 7, the speed governor 400 includes an input member 411, an output member 412, a spring member 413, a housing 414, an adjustment member 415, a movable member 416, and a fixed cylinder 417.
[0048] The input member 411 is a shaft-shaped member that rotates integrally with the handle 301. One end of the input member 411 is formed with a male thread 421 that screws into the nut member 303. The other end of the input member 411 is formed with a notched portion 422 to which one end of the spring member 413 is connected. A flange 423 that projects radially outward is provided at the middle portion of the input member 411.
[0049] The output member 412 rotates in response to the rotation of the input member 411 and transmits power for reeling in the fishing line. The output member 412 is composed of two members: a bottom member 412A and a cover member 412B. The bottom member 412A includes a base member 431, a storage cylinder member 432, and a fixed cylinder member 433. The base member 431 is a plate-like member arranged perpendicular to the rotation axis C. A through-hole 431a is formed in the center of the base member 431, into which the tip 425 of the input member 411 is inserted. The storage cylinder member 432 is a cylindrical member extending from the base member 431 toward the handle 301, parallel to the rotation axis C. A spring member 413 is disposed in the hollow portion formed by the base member 431 and the storage cylinder member 432. The fixed cylinder member 433 is a cylindrical member extending from the base member 431 toward the cover member 13, parallel to the rotation axis C. A thread groove that screws onto the drive gear shaft 2 is formed on the inner peripheral surface of the fixed cylindrical portion 433. This allows the output member 412 (412A, 412B) and the drive gear shaft 2 to rotate synchronously. In addition, the output member 412 and the drive gear shaft 2 are attachable and detachable.
[0050] The cover member 412B is a member arranged to cover the open side of the bottom member 412A. The cover member 412B includes a base plate portion 441, a first cylindrical portion 442, a second cylindrical portion 443, and a resistance protrusion 444. The base plate portion 441 is arranged perpendicular to the rotation axis C and is a plate-shaped portion covering the cylindrical storage portion 432. The first cylindrical portion 442 is a cylindrical portion extending from the base plate portion 441 toward the handle 301 and covering the outer periphery of the input member 411. A step portion 442a formed with a different inner diameter is formed inside the tip side of the first cylindrical portion 442. The second cylindrical portion 443 is a cylindrical portion extending from the base plate portion 441 toward the cover member 13 and in circumferential contact with the outer periphery of the cylindrical storage portion 432. The base plate portion 431 and the second cylindrical portion 443 are joined via multiple joining members P.
[0051] The resistance protrusion 444 rises from the base plate portion 441 toward the handle 301 in the circumferential direction on the radially outer side of the first cylindrical portion 442. The resistance protrusion 444 tapers toward the tip (trapezoidal cross section). The resistance protrusion 444 may have another shape.
[0052] The spring member 413 is a member that can accumulate and generate a restoring force in the rotational direction corresponding to multiple rotations of the handle 301 between the input member 411 and the output member 412. In this embodiment, a power spring is used as the spring member 413, but other springs may also be used. One end of the spring member 413 is connected to the notched portion 422 of the input member 411, and the other end is connected to a part of the storage cylindrical portion 432 of the output member 412.
[0053] 7, the housing 414 includes a main body cylindrical portion 451, a lid portion 452, and a flange portion 453. The main body cylindrical portion 451 is a cylindrical portion that covers the radial outside of the output member 412 and the movable member 416. A through hole 451a through which the guide pin 473 of the adjustment member 415 passes is formed in a part of the main body cylindrical portion 451. The through hole 451a extends parallel to the rotation axis C, as shown in FIG.
[0054] The lid portion 452 is a plate-like portion that covers the handle 301 side of the main body cylindrical portion 451. A through-hole 452a through which the first cylindrical portion 442 passes is formed in the center of the lid portion 452. In addition, an engagement groove 454 is formed on the outer periphery of the lid portion 452, with which the adjustment member 415 engages around the housing 414 so as to be relatively rotatable.
[0055] The flange portion 453 projects radially outward from the outer circumferential surface of the end portion of the main body cylindrical portion 451 on the lid member 13 side. The flange portion 453 is joined to the fixed cylinder 417 via a plurality of joining members Q.
[0056] The adjustment member 415 is a member that adjusts the viscous force in the resistance generating means. The adjustment member 415 is cylindrical and disposed on the outer periphery of the housing 414 so as to be rotatable relative to the housing 414. The adjustment member 415 includes an adjustment rib 461, an engagement protrusion 462, and a cam groove 463. The adjustment rib 461 is formed unevenly around the outer periphery of the adjustment member 415 so as to make it easy to rotate with the user's fingers. The engagement protrusion 462 is a groove that rotatably engages with the engagement groove 454 of the housing 414. The cam groove 463 is cut out in a generally spiral shape around the circumferential direction of the adjustment member 415, as shown in FIG. 5 .
[0057] The movable member 416 is a ring-shaped member that is disposed on the outer periphery of the first cylindrical portion 442 of the cover member 412B inside the housing 414. A resistance groove 471 is formed in the circumferential direction on the bottom surface of the movable member 416. The resistance groove 471 has a generally trapezoidal cross section so that the resistance protrusion 444 can be inserted therein. The space formed by the resistance protrusion 444 and the resistance groove 471 forms a storage space N. The storage space N is filled with grease, thereby forming a "resistance generating means."
[0058] Furthermore, a guide pin 473 is arranged on the side surface of the movable member 416 so as to protrude outward. The guide pin 473 is inserted through the through hole 451a and engaged with the cam groove 463. When the user rotates the adjustment member 415 in one direction or the other around the rotation axis C, the cam groove 463 also moves circumferentially, and the cam mechanism moves the guide pin 472 in the height direction within the through hole 451a. Accordingly, the movable member 416 moves in the height direction relative to the cover member 412B. In other words, the movable member 416 is formed so as to be unable to rotate about the rotation axis C but to be movable in the height direction.
[0059] As shown in Figure 7, the closer movable member 416 is to cover member 412B, the smaller the storage space N, resulting in a high viscosity state. On the other hand, as shown in Figure 8, the farther movable member 416 is from cover member 412B, the larger the storage space N, resulting in a low viscosity state. The viscosity of the resistance generating means can be finely changed depending on the amount of rotation of adjustment member 415. In this embodiment, the resistance protrusion 444 is provided on the cover member 412B and the resistance groove 471 is provided on the movable member 416, but the resistance groove may be provided on the cover member 412B and the resistance protrusion may be provided on the movable member 416.
[0060] The fixed barrel 417 is a cylindrical member disposed between the housing 414 and the cover member 13. A first recess 481 is formed on the handle 301 side of the fixed barrel 417, and a second recess 482 is formed on the cover member 13 side. The output member 412 is disposed in the first recess 481 so as to be relatively rotatable. The center of the cover member 13 is disposed in the second recess 482. A protrusion 484 provided on the end of the fixed barrel 417 is fitted into the recessed groove 13c of the cover member 13. A through-hole 483 is formed in the bottom of the first recess 481, penetrating into the second recess 482. The fixed barrel portion 433 of the output member 412 is inserted into the through-hole 483.
[0061] Next, we will explain the effects of the handle device 300 according to the second embodiment. The handle device 300 has two winding modes, a normal winding mode and a constant speed winding mode, which can be selected by rotating the lock lever 302 in one direction or the other around the rotation axis C.
[0062] <Normal winding mode, locked on> 9, when the lock lever 302 is rotated in one direction around the rotation axis C, the input member 411 and the output member 412 come into contact with each other, and the reel enters the normal reeling mode. In other words, in the normal mode, the reel line reeling speed is variable in response to the user's handle operation, just like a typical fishing reel.
[0063] More specifically, as shown in Fig. 9, when the lock lever 302 is rotated in one direction around the rotation axis C, the nut member 303 is displaced toward the output member 412 due to the threaded engagement between the nut member 303 and the male thread 421 of the input member 411, and the nut member 303 and the output member 412 come into surface contact. Furthermore, the flange 423 of the input member 411 engages with the stepped portion 442a of the first cylindrical portion 442, so that the tip side of the first cylindrical portion 442 is sandwiched between the nut member 303 and the flange 423. As a result, a frictional force is generated between the bottom surface of the nut member 303 and the end face of the first cylindrical portion 442 of the output member 412. In other words, a large axial force is generated between the input-side friction generating portion (the bottom surface of the nut member 303) and the output-side friction generating portion (the end face of the first cylindrical portion 442), thereby generating a frictional force in the rotational direction. As described above, the handle 301, input member 411, and output member 412 rotate synchronously as a unit, so that the fishing line can be reeled in by rotating the handle 301, just like with a typical fishing reel. When the user wants to reel in the fishing line with a tension greater than a predetermined level, such as when attaching or detaching the handle device 300 to or from the reel body 1, or when a fish is hooked, the user should use the normal reeling mode.
[0064] <Constant speed winding mode, lock-off state> 7, when the lock lever 302 is rotated in the other direction around the rotation axis C, the output member 412 and the nut member 303 are separated, and the constant speed winding mode is entered, in which the fishing line can be wound at a constant speed. In other words, when the lock lever 302 is rotated in the other direction around the rotation axis C, the nut member 303 is displaced toward the handle 301 due to the engagement of the nut member 303 with the male thread 421 of the input member 411, and the nut member 303 is separated from the output member 412. As a result, the input of the input member 411 is not directly transmitted to the output member 412.
[0065] In the constant speed winding mode, when the user turns the handle 301 in one direction, a restoring force is accumulated in the spring member 413. Initially, the output member 412 does not rotate, and the restoring force is accumulated in the spring member 413. In other words, the spring member 413 is tightened via the input member 411. It is preferable to turn the handle 301 multiple times, but it is sufficient to turn it at least 90 degrees or more.
[0066] Thereafter, the output member 412 gradually begins to rotate according to the amount of charge stored in the spring member 413. At this time, the rotation speed of the output member 412 changes depending on the amount of charge stored in the spring member 413. The rotation speed of the input member 411 does not directly depend on the rotation speed of the output member 412. Even if the rotation operation of the handle 301 is stopped, if the amount of charge stored in the spring member 413 is sufficiently large, the output member 412 continues to receive torque in the rotational direction and continues to rotate at a roughly constant speed. As the amount of charge stored in the spring member 413 decreases, the rotation of the output member 412 also slows down and eventually stops.
[0067] This reduces the change in the rotation speed of the output member 412 even if the speed at which the user rotates the handle 301 changes. This reduces the variation in the speed at which the fishing reel R1 reels in the fishing line, and increases the chances of a fish biting when using a specific fishing method, such as when using an artificial bait.
[0068] These effects will now be described in detail using model diagrams. Fig. 10 is a model diagram showing the configuration of a conventional handle and rotor. Fig. 11 is a model diagram showing the configuration of a handle and rotor according to a second embodiment.
[0069] As shown in Figure 10, if the position of the rotor F2 is Y, the position of the handle F1 is X, and the gear ratio is G, then in a conventional reel, the position of the rotor F2 is multiplied by the gear ratio of the position of the handle F1, so Y = GX. Therefore, if there is speed unevenness in the handle speed dX / dt, the speed unevenness dY / dt of the rotor F2 will occur in proportion to the speed unevenness of the handle F1.
[0070] 11, in this embodiment, where the mass of the rotor 4 is m, the spring constant is k, and the damping coefficient of the resistance generating means is c, the equation of motion holds for the mass and position of the rotor 4, m·Y=k(XY)-cY, which is a so-called second-order lag system. In other words, when the handle 301 is moved, the rotor 4 gradually moves toward a stable position (a state where the spring charge is 0).
[0071] Therefore, even if there is speed unevenness in the handle speed dX / dt, if the frequency of that speed unevenness is below a predetermined value, the secondary lag system will apply a low-pass filter effect to the high frequency components of the speed unevenness, and the rotor 4 itself will be able to operate with relatively little speed change. Note that the rotor 4 is normally restricted from rotating in the reverse direction by a one-way clutch, ratchet, etc., so unlike the behavior of a typical secondary lag system, vibration of the rotor 4 will not occur.
[0072] In the above explanation, a proportional type spring was used, in which the repulsive force of the spring increases in proportion to the amount of stored charge in spring member 413, but the present invention is not limited to this. A spring with a nonlinear characteristic between the amount of stored charge and the repulsive force, such as a constant force spring or a contact type spiral spring, may also be used.
[0073] As a result, even if the amount of stored energy in spring element 413 changes, the change in the repulsive force of spring element 413 can be reduced, thereby reducing speed fluctuations of rotor 4. Furthermore, by using a power spring as spring element 413, a repulsive force can be generated without breaking even for large angular changes such as an accumulated amount of 360° or more, so that the effect can be exerted even if speed fluctuations become large. Furthermore, because energy can be stored in a relatively small space, the overall size of the device can be reduced.
[0074] The spring used in the present invention is not limited to a power spring, but may be any spring that stores energy by accumulating torque in the torsional direction. Such spring members include torsion springs (torsion springs) in addition to power springs. In this case, too, it is preferable to increase the number of turns so that the range of possible angles can be increased. Since speed fluctuations that occur when the user operates the handle 301 often depend on the angle between the handle 301 and the reel body, it is desirable for the spring member used in the present invention to have an allowable displacement of 360° or more.
[0075] Furthermore, the resistance generating means of this embodiment can change the winding speed by adjusting the viscosity of the grease. That is, as shown in Fig. 7, when the adjusting member 415 is rotated to create a high viscosity state, the output member 412 also experiences a large resistance and rotates relatively slowly. Therefore, when the high viscosity state is created, the grease can be wound evenly at a relatively slow speed.
[0076] 8, when the adjustment member 415 is rotated to set the viscosity to low, the resistance applied to the output member 412 is small and the output member 412 rotates relatively quickly. Therefore, when the viscosity is low, the spool can be wound at a relatively fast speed without unevenness.
[0077] Here, the mechanism for regulating the speed of the rotor 4 by resistance generating means such as applying viscous force will be described with reference to Figures 12 and 13. Figure 12 is a graph showing the relationship between spring charge and torque in the handle device of a fishing reel according to a second embodiment. Figure 13 is a graph showing the relationship between handle speed and resistance torque in the handle device of a fishing reel according to the second embodiment.
[0078] When a contact-type spiral spring is used as the spring member, the torque increases roughly in proportion to the spring charge when the spring charge is small, as shown in Figure 12. As the spring charge increases, a region (region A) appears where the torque remains almost constant despite an increase in the spring charge due to the influence of contact friction. The torque at this time is defined as T.
[0079] On the other hand, as shown in FIG. 13, resistance generating means such as viscous force applying means generate a resistance torque due to a reaction force that increases depending on the steering wheel speed. At a speed V1 where the resistance torque is T, the restoring torque of the spring member 413 and the torque of the resistance generating means are balanced. In other words, the rotor 4 reaches a stable state at a speed V1. As the rotor 4 rotates, the spring member 413 gradually loses its stored amount, but as the user continues to turn the steering wheel 301, the spring member 413 is recharged. If the stored amount remains within the range A, the rotor 4 can maintain the state of speed V1. Therefore, the larger the angle range of A, the more the user's steering operation can be reduced inconsistently. It is desirable to make the range A larger by 90° or more.
[0080] Furthermore, as in this embodiment, if the characteristics of the reaction force generated by the resistance generating means can be adjusted, the stable speed of the rotor 4 can be adjusted. If the state in which viscosity is high is set as setting 1 and the state in which viscosity is low is set as setting 2, then in setting 1 the rotor stabilizes at speed V1. In setting 2 the rotor stabilizes at speed V2, which is faster than speed V1. In this way, if the resistance generating means can be adjusted, any speed can be made the stable speed.
[0081] 12, the relationship between spring charge and torque is preferably such that the graph has an upwardly convex characteristic (a relationship of lower order than a proportional relationship). This is because the characteristic is such that torque fluctuations are small relative to fluctuations in spring charge, and in this case, the allowable angle range A of the handle 301 becomes wider.
[0082] 13, the relationship between the steering wheel speed and the resistance torque generated by the resistance generating means is preferably such that the graph curve is downwardly convex (a higher-order relationship than a proportional relationship). This is because when the torque T generated by the spring member 413 fluctuates, the fluctuation in the balancing speed V1 becomes small.
[0083] Furthermore, according to this embodiment, since the lock lever 302 is provided, the normal winding mode and the constant speed winding mode can be selected according to the user's preference. That is, when a user wants to reduce the unevenness of the speed at which the fishing line is reeled in, the user operates the lock lever 302 to the OFF side. This reduces the unevenness of the speed at which the fishing reel R1 reels in the fishing line, even if there is an unevenness in the speed at which the handle 301 is reeled in. On the other hand, in situations where the user wants to directly rotate the output member 412, such as when reeling in a fish that has bitten on the hook, when the hook gets snagged, or when attaching or detaching the handle 301, even if the user operates the handle 301, the torque is transmitted to the output member 412 via the spring member 413, and therefore sufficient operating torque may not be applied to the output member 412. In such situations, the lock lever 302 is operated to the ON side. This allows sufficient torque to be transmitted to the output member 412, allowing the rotor 4 to be operated directly.
[0084] In addition, in the resistance generating means, the viscosity of the adjustment member 415 in response to the rotational operation can be freely set by appropriately designing the type of viscous fluid such as grease, the shape of the resistance protrusion 444 and the resistance groove 471, the configuration of the cam mechanism, etc.
[0085] [Third embodiment] Next, a third embodiment of the present invention will be described. The resistance generating means used in the present invention is not limited to those using the viscous force of a viscous fluid as described above. For example, it may be one that uses centrifugal force, as shown in FIG. 14. FIG. 14 is a cross-sectional view showing the resistance generating means of the handle device of a fishing reel according to the third embodiment. In this embodiment, the resistance generating means is provided on the rotor 4 of the fishing reel R1.
[0086] In the resistance generating means 550 of this embodiment, the rotor 4 has a guide rod 552 extending in the radial direction. A centrifugal brake shoe 553 is supported on the guide rod 552 so as to be capable of translational movement in the radial direction. When the rotor 4 rotates at high speed, centrifugal force is generated in the centrifugal brake shoe 553. This force is expressed as MRω, where M is the mass of the centrifugal brake shoe 553, R is the distance from the center of rotation to the center of gravity, and ω is the angular velocity of the rotor 4. 2 The centrifugal brake shoe 553 has an outer wall 554 that is integral with the reel body 1 on the outside, and when the rotor 4 rotates, a frictional force is generated between the centrifugal brake shoe 553 and the outer wall 554. This frictional force realizes a function equivalent to the resistance generating means that uses viscous force in the above-described embodiment.
[0087] The resistance generating means using centrifugal force as in this embodiment can generate a reaction force that is not dependent on the characteristics of the viscous fluid, and therefore can provide a reaction force that is relatively stable against temperature changes. The resistance generating means of the present invention may act on the handle shaft as in the previously described embodiment, or may be built into the reel body 1 and act on the rotor shaft as in this embodiment. Generally, the rotor shaft is often accelerated more than the handle shaft, so it is easier to generate a reaction force due to centrifugal force by having the resistance generating means act on the rotor shaft.
[0088] The speed regulator of the present invention can also be used in a casting baitcasting reel. When the speed regulator of the present invention is used in a casting baitcasting reel, most casting baitcasting reels generally have a casting braking means, and this casting braking means can be used as the resistance generating means of the present invention. The casting braking means can increase the braking force the faster the spool rotates, and in many cases is equipped with a mechanism for adjusting the braking force. Known casting braking means include those that utilize centrifugal force and frictional force, those that utilize eddy currents generated in a conductor in a magnetic field, and those that utilize the effect of dynamic braking generated in a coil in a magnetic field. The casting braking means provides a braking force to prevent the fishing line from getting tangled when it is released, but when used in the present invention, it can also serve to generate a braking force to balance the spring's restoring force when the fishing line is reeled in.
[0089] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described. The resistance generating means used in the present invention is not limited to those using the viscous force of a viscous fluid as described above. For example, it may be one that uses an escapement, as shown in Figures 15 and 16. Figures 15 and 16 are plan sectional views showing the resistance generating means of a fishing reel handle device according to the fourth embodiment.
[0090] 15 and 16, the resistance generating means according to this embodiment is realized by the action of a gondola 651 provided on the output member 412 and an escapement 653. The gondola 651 has a plurality of teeth formed to protrude radially from the rotation axis of the output member 412 as its central axis, and alternately comes into contact with two pawls 654, 655 formed on both ends of the escapement 653. The escapement 653 is pivotally supported by a rotation axis 652 provided on the fixed barrel 417 so as to be able to swing.
[0091] As shown in FIG. 15 , when one pawl 655 of escapement 653 is separated from escape wheel 651, the other pawl 654 is engaged with escape wheel 651, and pawl 654 receives a force in a direction away from escape wheel 651 due to the action of the accumulated spring member 413 when it is released. When pawl 654 releases from escape wheel 651, escape wheel 651 rotates by one tooth. When the other pawl 655 of escapement 653 engages with escape wheel 651, output member 412 temporarily stops rotating, resulting in the state shown in FIG. 16 . In this state, pawl 655 receives a force in a direction away from escape wheel 651 due to the action of the accumulated spring member 413 when it is released. When pawl 654 releases from escape wheel 651, escape wheel 651 rotates by one tooth, resulting in the state shown in FIG. 15 .
[0092] In this way, the output member 412 continues to rotate intermittently, one tooth at a time, due to the action of the escapement wheel 651 and the escapement 653. At this time, the period in which the escapement 653 makes one reciprocating motion is determined by the mass and spring constant of the escapement 653, and is therefore hardly affected by the amount of charge stored in the spring member 413. Therefore, it is possible to configure a speed governor with very little fluctuation in the rotation speed of the rotor 4. On the other hand, a configuration using the escapement wheel 651 and the escapement 653 as in this embodiment has disadvantages, such as the tendency to generate noise and the difficulty of moving the rotor 4 at speeds other than the specified speed.
[0093] Although the embodiments of the present invention have been described above, appropriate design changes are possible within the scope of the present invention. For example, the resistance generating means may be omitted. Although the presence of the resistance generating means can further suppress speed fluctuations, omitting the resistance generating means and using only the spring element-mass element can still have the effect of reducing speed fluctuations (second-order delay system: the effect of components with higher frequencies than the natural frequency determined by the inertial mass of the spring and rotor being less likely to be transmitted). Furthermore, the uneven rotation speed that occurs when the user turns the handle reaches a frequency of around 10 Hz at the fastest, so it is desirable to set the natural frequency, which is determined by the inertial mass of the spring and rotor, to a lower frequency than this.
[0094] Furthermore, the handle device (or the speed governor device alone) of this embodiment can be retrofitted to an existing fishing reel. On the other hand, if the speed regulating device of this embodiment is built into the reel body, part of the reel body's housing can also serve as the housing for the speed regulating device, making it possible to make the entire device smaller and lighter after the speed regulating device is installed.
[0095] Furthermore, instead of the lock mechanism of the second embodiment, a second operating member (lock lever) may be attached to the output member. In this case, the first operating member (handle) is operated when the speed-governing effect is to be activated, and the second operating member (lock lever) is operated when the speed-governing effect is not to be activated. In this way, a function similar to that of a system that locks an input member and an output member can be achieved. Comparing the two systems, the system that locks an input member and an output member (system of the second embodiment) requires a large contact friction force to be generated between the input member and the output member during locking, which has issues such as being susceptible to wear and limiting the torque capacity that can lock the input member and the output member. On the other hand, even when the first operating member (handle 301) is rotated, it does not intersect with the second operating member (lock lever 302), which has the advantage of good operability.
[0096] On the other hand, in the case of a system in which a second operating member is provided on the output member, the output member and operating handle are immovable, which has the advantage of being able to transmit a large torque to the output member and being immune to the effects of wear.However, when rotating the first operating member, it is likely to cross the second operating member, making it difficult to ensure operability.
