Description

The present invention relates to the technical field of fishing reels equipped with a drag mechanism that rotates the spool against a braking load when an excessive load acts in the line-releasing direction.

Generally, some fishing reels are equipped with a drag mechanism in the power transmission path between the handle shaft, which rotates based on handle operation, and the spool shaft of a spool for winding fishing line (main line, fishing line, fishing line). The drag mechanism applies an adjusted braking load (braking force) to the spool's rotation in the line-releasing direction, and is configured to allow the spool to rotate in the line-releasing direction if a load exceeding this braking load acts on the spool (see, for example, Patent Document 1).
In such fishing reels with a drag mechanism, for example if the reel is a spinning reel, a drag operating device is provided near the handle and the braking load can be adjusted from a no-load state to a maximum-load state based on the operation of the drag operating device.

JP 2012-50398 A

However, when actually fishing (actual fishing), for example, if a big fish is caught, the adjusted braking load may be too weak and the spool may continue to rotate in the line-releasing direction, making it impossible to reel in the fishing line. To deal with this, the drag operating device may be operated in a direction that increases the braking load, or conversely, if the braking load is too large, the braking load may be operated in a direction that decreases it. However, in these cases, the adjustment range of conventional drag operating devices is wide, from no load to maximum load, so even a small adjustment can result in a large change in the braking load. As a result, even if you operate the drag operating device slightly during actual fishing, the tension (tension) of the fishing line can suddenly increase or decrease, which can cause poor adjustment and lead to the line breaking, allowing your catch to escape. For this reason, drag adjustment in such a situation requires extremely careful operation, but it is difficult to adjust the drag so carefully when you have caught a large fish and are in the middle of handling it, due to the anxiety of the angler. As a result, drag adjustment is not done properly, and the line often breaks, causing the fish to escape. The problem that this invention aims to solve is to solve this problem.

The present invention has been made in view of the above-mentioned circumstances and with the objective of solving these problems. The invention of claim 1 relates to a fishing reel equipped with a drag mechanism which applies an adjustable braking load to a rotational load in the line-releasing direction of the spool in a power transmission path between a handle shaft which rotates based on handle operation and a spool shaft of a spool on which fishing line is wound, and which is configured to allow the spool to rotate in the line-releasing direction when a load in the line-releasing direction that exceeds the adjusted braking load acts on the spool, the drag mechanism being provided with a drag operating device for adjusting the braking load of the drag mechanism, the drag operating device comprising a first drag operating device which is operable to adjust the braking load from a no-load state to a maximum-load state, and a second drag operating device which is operable to increase or decrease the braking load based on the braking load adjusted by the first drag operating device, the first drag operating device being rotated about the axis of the handle shaft to move in the axial direction of the handle shaft, and the drag mechanism being configured to move between the handle shaft side and the spool shaft the second drag operating device is provided so as to be movable in the axial direction of the handle shaft while being in contact with the drag spring side member in order to change the urging force of the drag spring, and is connected to the first drag operating device via a cam mechanism having a function of moving the first drag operating device in the axial direction of the handle shaft relative to the first drag operating device, so that when the first drag operating device is rotated around the axial direction of the handle shaft, the first drag operating device moves together with the second drag operating device in the axial direction of the handle shaft, and the braking load is adjusted from an unloaded state to a maximum loaded state, and when the second drag operating device is rotated around the axial direction of the handle shaft, the second drag operating device moves in the axial direction of the handle shaft independently of the first drag operating device due to the relative movement function of the cam mechanism, and the braking load is increased or decreased based on the operating position of the first drag operating device .
The invention of claim 2 is a fishing reel as described in claim 1, characterized in that a recognition means is provided between the second drag operating device and the drag spring mechanism for recognizing that the second drag operating device is positioned in the intermediate set position.

By adopting the invention of claim 1, in a fishing reel equipped with a drag mechanism, in addition to the conventional first drag operating device that can adjust the braking load of the drag mechanism from an unloaded state to a maximum load state, a second drag operating device is provided that can adjust the braking load to an increased or decreased state based on the braking load adjusted by the first drag operating device. As a result, by operating the second drag operating device, delicate drag adjustment different from the drag adjustment by the first drag operating device can be made, improving operability, and in cases where a large fish is caught, accurate drag adjustment is possible, reducing the occurrence of line breakage, etc.
Furthermore, when the first drag operating device is rotated about the axis of the handle shaft, it moves in the axial direction of the handle shaft together with the second drag operating device, and the braking load can be adjusted from an unloaded state to a maximum load state. On the other hand, when the second drag operating device is rotated about the axis of the handle shaft, it moves in the axial direction of the handle shaft independently of the first drag operating device, due to the relative movement function of the cam mechanism, and the braking load can be increased or decreased based on the operating position of the first drag operating device. As a result, delicate increase or decrease adjustments of the braking load can be made simply and reliably by simply operating the second drag operating device, improving operability.
According to the invention as defined in claim 2 , it is possible to reliably recognize that the second drag operating device is in the intermediate set position, thereby improving operability.

The following describes the embodiment of the present invention with reference to the drawings. In the drawings, reference numeral 1 denotes a fishing reel, which has a double-bearing casing body including left and right casings 2, 3 on the drive and driven sides and a connecting part 4 for connecting the casings 2, 3, and the legs 5 on the connecting part 4 are detachably attached to a support (reel seat (not shown)) on the fishing rod, allowing the reel 1 to be set on the fishing rod.

A spool shaft 6 is rotatably supported at its left and right ends by the left and right casings 2, 3 via bearings 6a, and a spool 7 is supported on the spool shaft 6 so as to rotate integrally therewith.
Meanwhile, a guide tube 8 is provided in front of the spool 7 with both left and right end edges supported by the left and right casings 2 and 3, and a helical shaft (Napier shaft, traverse cam shaft) 9 constituting the level wind mechanism L is rotatably supported by the guide tube 8 via a bearing 9a. An end 9b of the helical shaft 9 in the driven side casing 3 is interlocked with an end 6b of the spool shaft 6 in the driven side casing 3 via a power transmission mechanism 10 using gears, so that the spool 7 and the helical shaft 8 rotate together in conjunction with the rotation of the spool shaft 6. Incidentally, the gear ratio of the power transmission mechanism 10 is set so that the helical shaft 9 rotates in a state of changing speed (decelerating) with respect to the rotation of the spool shaft 6.

The guide tube 8 has an opening formed in the peripheral surface of the lower half side, so that the peripheral surface of the helical shaft 9 is exposed (visible), and a guide rod (not shown) is provided near the guide tube 8 with both left and right ends supported by the front ends of the left and right casings 2, 3, and a guide body (guide) 13 is provided to guide the fishing line 12 wound around the spool 7 to the left and right by the guide rod.

As described above, when the spool 7 and the helical shaft 9 rotate in conjunction with the rotation of the spool shaft 6, the guide body 13 moves back and forth from side to side while being guided by the helical groove 9c provided on the helical shaft 9, so that the fishing line 12 is wound onto and unwound from the spool 7 while being guided by the guide body 13.
When the fishing line 12 is wound around the spool 7 with the guidance of the guide body 13, the fishing line 12 is wound in layers as the guide body 13 moves back and forth repeatedly. In this way, a level wind mechanism L, which will be described later, is configured to wind the fishing line 12 evenly around the spool 7.

Furthermore, in the reel 1 of this embodiment, a clutch operating device 15 for constituting a clutch mechanism is axially supported between the rear ends of the left and right casings 2, 3 so as to be freely swingable in the vertical direction. By operating the clutch operating device 15, the power transmission from the handle shaft 14a (described later) to the spool shaft 7 is cut off, and the spool 7 together with the spool shaft 6 is set in a free state so as to rotate freely. However, as the specific configuration of such a clutch mechanism is a conventionally known one, further detailed explanation will be omitted.
In addition, the drive side casing 2 is provided with a casting operation tool 16 for constituting a casting mechanism. By rotating the casting operation tool 16, a driven gear 17, which is mounted on the spool shaft 6 so as to be rotatable and movable in the axial direction, moves in the axial direction of the spool shaft 6. This changes the biasing force of the casting spring 16a, thereby applying an adjustable brake to the free rotation of the spool 7. As this casting mechanism is also a conventionally known one, further detailed explanation will be omitted.

On the other hand, the handle 14 disposed on the drive side casing 2 side is integrally attached to the tip of the handle shaft 14a which is rotatably supported by the drive side casing 2 via a bearing 14b, and a drive gear 18 meshed with the driven gear 17 is rotatably provided on the handle shaft 14a, so that when the handle shaft 14a rotates, the rotational power is transmitted to the spool shaft 6. A drag mechanism D is provided on the power transmission path between the drive gear 18 and the handle shaft 14a.
The drag mechanism D is configured to apply a braking load (braking force) that is set against the rotation of the spool 7 in the line-releasing direction, and when a load that exceeds the set braking load acts on the spool 7 from the side of the reeled out fishing line 12, it is configured to allow the spool 7 to rotate in the reeling direction of the fishing line 12 against the braking load. The drag mechanism D of this embodiment is located outside the drive side casing 2, and is provided with a first drag operating device 19 that corresponds to an operating device of a conventional drag mechanism, and a second drag operating device 20 that is arranged between the first drag operating device 19 and the drive side casing 2.

The drag mechanism D is equipped with a friction plate braking part Z that is installed inside the drive side casing 2. The friction braking part Z is made up of a first friction plate 24 that is arranged to rotate integrally with the handle shaft 14a and a second friction plate 25 that is arranged to rotate integrally with the drive gear 18, which are arranged in a stacked manner, while the bearing 14b is configured to be freely movable in the axial direction relative to the handle shaft 14a. The stacked first and second friction plates 24, 25 are configured so that, as described below, when the first and second drag operating devices 19, 20 are adjusted, the bearing 14b moves left and right while the biasing force of the drag spring 23 is adjusted, and presses the receiving member 26 that constitutes the friction braking part Z, thereby adjusting the friction force of the friction braking part Z, and the drag mechanism D is configured to exert an adjusted braking load, and the configuration of the friction braking part Z is also conventionally known.

Meanwhile, the first drag operating device 19 is a round-top knob type with a small diameter, whereas the second drag operating device 20 is a large-diameter device that extends outwardly longer than the first drag operating device 19, so that the fingers of the hand gripping the grip portion 14e of the handle 14 can be stretched out to operate it beyond the first drag operating device 19 (without being hindered by the first drag operating device 19). The second drag operating device 20 can be of various shapes as required, such as a disk shape, a star shape with multiple operating rods extending radially, or a single shape with one operating rod, but in this embodiment, two operating rods 20f protrude.
The first drag operating device 19 is configured so that its axial portion 19a meshes with a thread groove 14c provided at the tip of the handle shaft 14a, and is configured to move relatively forward and backward in the axial direction of the handle shaft 14a when rotated. Furthermore, the first drag operating device 19 has a surface portion (inner surface portion) facing the drive-side casing 2 between the axial portion 19a and the outer circumferential edge portion 19b, in which a recessed fitting portion 19c having an arc-shaped groove shape is formed, and the outer circumferential portion 21a of the arc-shaped operating member 21 is fitted inside the recessed fitting portion 19c.

The actuating member 21 is configured to be freely movable in the axial direction with rotation around the axis restricted at the thread groove 14c of the handle shaft 14a by having the axial portion 21b fitted onto the chamfered portion 14d provided on the handle shaft 14a. However, a plurality of cam receivers 21c are provided on the outer periphery 21a of the actuating member 21 at an arrangement pitch with a predetermined angle (e.g., 180 degrees, 120 degrees, etc.) in the circumferential direction so as to protrude toward the drive side casing 2 side.
In addition, the axial portion 21b of the operating member 21 protrudes toward the drag spring 23, and the protruding tip 21d of the axial portion 21b is fitted through the axial portion 20a of the second drag operating device 20 so as to be freely rotatable about the axis and movable in the axial direction, and is configured to face the receiving plate 23a provided on the drag spring 23 with a gap (a clearance that serves as an escape when the second drag operating device 20, which will be described later, is operated in a direction to reduce the braking load).
When the first drag operating device 19 is rotated, the first drag operating device 19 is configured to move back and forth in the axial direction (left and right direction) relative to the handle shaft 14a together with an operating member 21, the rotation of which is restricted around the axis.

On the other hand, the second drag operating device 20 has an axial portion 20a rotatably fitted around the axial portion 21b of the actuating member, and a recessed portion 20b having an arc-shaped groove shape is formed in a portion facing the outer peripheral portion 21a of the actuating member, and the drag elastic device 23 is housed in the recessed portion 20b. A receiving plate 23a of the drag elastic device 23 abuts against and faces a bottom portion 20c of the recessed portion 20b.
Incidentally, the drag spring 23 is provided in a state in which it is movable in the axial direction relative to the handle shaft 14a but is restricted from rotating about the axis.

Furthermore, an arc-shaped recessed portion 20d is formed on the surface (outer surface) of the second drag operating device 20 facing the first drag operating device 19, and a locking body 20e is incorporated into the bottom surface of the recessed portion 20d at a predetermined angle (spacing) around the axis. A cam body 22 having a locking hole portion 22a that locks onto the protruding head of the locking body 20e is provided so as to fit inside the recessed portion 20c.
The surface (outer surface) of the cam body 22 facing the first drag operating device 19 is a cam surface 22b, which is an inclined surface corresponding to the arrangement pitch of the actuating bodies 21c provided on the actuating member 21, and is configured so that the actuating bodies 21c abut against the cam surface 22b.
Furthermore, the inclination of cam surface 22b does not need to be flat, but may be a concave arc surface or, conversely, a convex arc surface. Such selection can accommodate various changes in the braking load adjustment when the second drag operating device 20 is operated, such as changing linearly, changing slowly at the beginning of the operation and changing quickly at the end of the operation, or conversely, changing quickly at the beginning of the operation and changing slowly at the end of the operation.
Furthermore, by selecting the inclination state (inclination angle) of cam surface 22b, the adjustment state of the braking load when second drag operating device 20 is operated (for example, the amount of change in braking load when second drag operating device 20 is rotated 15 degrees) can be set arbitrarily as needed.

When the first drag operating device 19 is rotated around the axis of the handle shaft 14a, the first drag operating device 19 moves in the axial direction of the handle shaft 14a together with the second drag operating device 20, which presses the drag spring 23 as described above, thereby adjusting the primary braking force from the no-load state to the maximum load state in the friction braking section Z (see Figure 6).

In contrast, when the first drag operating device 19 is operated to an appropriate adjustment position and the second drag operating device 20 is rotated around the axis of the handle shaft 14a, the contact position of the actuator 21c against the cam surface 22b changes. As a result, without changing the operating state of the first drag operating device 19, the second drag operating device 20 moves left and right along the axis of the handle shaft 14a, changing the pressing force on the drag spring 23. As a result, a secondary adjustment is made in which the braking load can be changed between the minimum braking load state and the maximum braking load state, which is the tilt range of the cam surface 22b, based on the operating state of the first drag operating device 19, in accordance with the operation of the second drag operating device 20 (see Figure 7).

In other words, in this device, a second drag operating system using the second drag operating device 20 is provided (interposed) in the drag operating transmission path from the first drag operating device 19 to the friction braking section Z, making it possible to perform a second drag adjustment based on the drag adjustment state by the first drag operating device 19.In this way, during actual fishing, accurate drag adjustment operation can be performed based on the drag adjustment state by the first drag operating device 19, which is expected to improve fishing results.
In this device, a positioning body 23b is extended from the drag spring 23, and when the second drag operating device 20 is set to the central position in the operating direction, the positioning body 23b abuts against a protrusion 20f provided on the inner surface of the recessed portion 20b of the second drag operating device 20, thereby confirming that the second drag operating device 20 is positioned in the central position.When the second drag operating device 20 is operated, the positioning body 23b passes over the protrusion 20f, which gives a clicking sensation, and allows the operating state of the second drag operating device 20 to be recognized.

In the present embodiment configured as described above, in the fishing reel 1 provided with the drag mechanism D, in addition to the conventional first drag operating device 19 capable of adjusting the braking load of the drag mechanism D from an unloaded state to a maximum loaded state, a second drag operating device 20 is further provided which can adjust the braking load by increasing or decreasing the braking load based on the braking load adjusted by the first drag operating device 19. As a result, by operating the second drag operating device 20, delicate drag adjustment different from the adjustment by the first drag operating device 19 can be made based on the braking load adjustment state by the first drag operating device 19, thereby improving operability. In the case where a large fish is caught, precise drag adjustment such as increasing or decreasing the braking load can be made, which reduces the occurrence of line breakage, etc.
Furthermore, in this case, the second drag operating device 20, which allows for delicate drag adjustment, extends radially outward more than the first drag operating device 19, thereby preventing accidental operation of the first drag operating device 19 and ensuring reliable operation.

Furthermore, in this reel, the first drag operating device 19 moves in the axial direction of the handle shaft 14a by rotating it about the axis of the handle shaft 14a, and the drag mechanism D is configured as a conventionally known device in which first and second friction plates 24, 25 on the handle shaft 14a side and the spool shaft 6 side are stacked together, and the stacked friction plates 24, 25 are provided with a friction braking section Z in which the braking load is adjusted by changing the biasing force of the drag elastic device 23. The second drag operating device 20 is provided so as to be freely movable in the axial direction of the handle shaft 14a while abutting against a receiving plate 23a, which is a member on the drag elastic device 23 side, in order to change the biasing force of the drag elastic device 23, and further, the second drag operating device 20 is connected via a cam mechanism including a cam body 22 having the function of moving the first drag operating device 19 relatively in the axial direction of the handle shaft 14a.
As a result, when the first drag operating device 19 is rotated about the axis of the handle shaft 14a, it moves together with the second drag operating device 20 in the axial direction of the handle shaft 14a, and the drag spring 23 adjusts the braking load in response to the operation of the first drag operating device 19, allowing the braking load to be adjusted from a no-load state to a maximum load state.

In contrast, when the second drag operating device 20 is rotated around the axis of the handle shaft 14a, the cam body 22 rotates together with the second drag operating device 20, while the first drag operating device 19 remains stationary without any rotational movement. As a result, the cam receiver 21c, which is immobile due to being provided on the first drag operating device 19 side, changes its contact position with the cam surface 22b of the cam body 22, which rotates together with the second drag operating device 20. As a result, while the cam body 22 is subjected to the biasing force of the drag spring 23, the second drag operating device 20 moves in the axial direction of the handle shaft 14a independently of the first drag operating device 19, and the braking load can be increased or decreased based on the operating position of the first drag operating device 19.

As a result, when the first drag operating device 19 is rotated around the axis of the handle shaft 14a, the first drag operating device 19 moves together with the second drag operating device 20 in the axis direction of the handle shaft 14a, and the braking load is adjusted from the no-load state to the maximum load state. On the other hand, when the second drag operating device 20 is rotated around the axis of the handle shaft 14a, the second drag operating device 20 moves in the axis direction of the handle shaft 14a independently of the first drag operating device 19 due to the relative movement function of the second drag operating device 20 with respect to the first drag operating device 19 by the cam mechanism equipped with the cam body 22, and the braking load can be increased or decreased based on the operating position of the first drag operating device 19. As a result, the braking load can be easily and reliably increased or decreased by simply operating the second drag operating device 20, improving operability.

Furthermore, with this device, when the positioning body 23b on the drag spring 23 abuts against the protrusion 23f on the second drag operating device 20, a feeling of resistance (click feeling) is felt, which enables the user to recognize that the second drag operating device 20 is located at a preset intermediate position within the operating range, thereby improving operability.
Incidentally, the configuration for allowing the intermediate position setting of the second drag operating device 20 to be recognized in this manner need not be one in which it is passed over a protrusion, but rather one in which it is fitted into a groove, and such a configuration can be set as appropriate as necessary.

The present invention can be used as a fishing reel with a drag function.
