Description

The present invention relates to a fishing reel with a lever drag mechanism.

Conventionally, as a fishing reel, a structure provided with a lever drag mechanism is known. The lever drag mechanism has a lever mounted on the reel body so as to be able to rotate by a certain angle. By rotating this lever toward one end, the frictional engagement force of the braking member with respect to the spool increases. By turning the lever toward the other end, the spool is separated from the braking member and the spool enters a free rotation state. there is

The above-described lever drag mechanism includes a cam member (rotating member) which is integrally rotatable with a lever and has a cam surface (inclined cam) formed thereon, and a moving member which faces the cam surface and moves in the axial direction. By rotating the lever, the moving member is moved in the axial direction by the inclined shape of the cam surface, and the spool moving in the axial direction together with the moving member is brought into contact with the braking member to adjust the braking force. there is In a fishing reel equipped with such a lever drag mechanism, the lever is rotated from the spool-free position to the maximum drag force position, but there is a possibility that the lever may be erroneously operated to cause the spool-free position during actual fishing. be. For example, if the spool accidentally becomes free while a fish is on the hook, the spool will rotate rapidly and cause a backlash phenomenon.

In order to solve such a problem, Patent Document 1 discloses a configuration in which a restriction projection is formed on the cam surface before the drag release position to restrict the rotation of the lever before the drag release position. disclosed. The restricting projection has a first inclined surface extending to the drag release position and a second inclined surface extending in the opposite direction to the drag released position. is made smaller than the inclination angle of , making it difficult to perform the rotation operation to the drag release position and to facilitate the rotation operation from the drag release position.

Patent No. 5135091

When the cam surface of the lever drag mechanism described above shifts from the drag action state to the free state, the braking force gradually weakens according to the inclination angle of the inclined surface, and the lower end of the inclined surface suddenly moves to the second inclined surface of the regulating projection. Since the shape is such that the transition is made, there is a problem that the click feeling at this position becomes too large and the smoothness is lacking.
That is, when the lever is rotated in the direction of releasing the drag force, the drag force is weakened by the inclination of the cam surface, and the lowermost end of the inclined surface shifts to the second inclined surface of the regulating protrusion in the opposite direction. The operation is caught, and the smoothness is lost at this position. Further, when the lever is turned to shift from the free state of the spool to the drag action state, the drag force is abruptly weakened by the inclination angle of the second inclined surface when the regulating protrusion is overcome via the first inclined surface, and the second Since the lowermost end of the inclined surface becomes a continuous inclined surface in the reverse direction, the rotation operation is caught at this position, and the smoothness is lost at this position.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and when a lever of a lever drag mechanism is rotated, a proper sense of moderation can be obtained between the drag action state and the free state, and the lever can be rotated. To provide a fishing reel which can be smoothly rotated.

In order to achieve the above object, a fishing reel according to the present invention is provided in a reel body, and includes a lever that can be rotated, a rotating member that rotates integrally with the lever, and a rotating member that faces the rotating member. and a moving member that moves in the axial direction when the lever is rotated by the action of the cam surface, and has a lever drag mechanism that applies a braking force to the spool by the axial movement of the moving member. a cam surface formed on either the rotating member or the moving member includes a braking area for adjusting the braking force of the spool by moving the moving member in the axial direction by rotating the lever; a non-movable region formed continuously with the region and not moving the moving member in the axial direction when the lever is rotated; and a release area for releasing the braking force of

According to the fishing reel configured as described above, when adjusting the drag, in the braking area, the braking force applied to the spool is arbitrarily adjusted according to the position of the lever when the operator rotates the lever. In this case, when the lever is rotated in the direction to release the braking force, at the position where the braking force is the weakest, an immovable region is provided in which the moving member is not axially moved continuously from the braking region. . When shifting to the non-movable region, there is no sudden change in the cam surface, and furthermore, even if the lever is rotated, the moving member does not move (the braking force does not change and the weakest braking force is maintained). When the lever is rotated from the braking area to the immovable area, it is possible to grasp a proper sense of moderation without causing a large catching. In addition, since a large resistance is not generated in the non-movable region and the movement continues to the release region, it is possible to smoothly rotate from the braking region to the release region. In addition, even when the lever is rotated to shift from the release area to the braking area, the provision of the immovable area prevents the cam surface from abruptly changing its angle, which hinders the rotation operation. It is possible to smoothly shift to the braking area without causing such a catch (a large sense of moderation).

According to the present invention, when the lever of the lever drag mechanism is operated to rotate, an appropriate sense of moderation can be obtained between the drag action state and the free state, and the rotation of the lever can be performed smoothly. You get a reel.

FIG. 2 is a diagram showing the configuration of the main parts of the lever drag mechanism, and FIG. 3 is a side view of the fishing reel shown in FIG. 1 as viewed from the handle side.

A reel body 1 of a fishing reel has left and right side plates 1A and 1B provided with a frame 2 integrated with left and right frames 2a and 2b and a right cover 3b mounted on the right frame 2b with a predetermined space therebetween. have. The left and right frames 2a and 2b are integrated via a plurality of columns, and the reel body 1 is attached to the reel seat (not shown) of the fishing rod by reel legs 2c provided on the lower columns. The left side plate 1A on the side opposite to the handle of the reel body of the present embodiment is composed of the left frame 2a itself, but it may be configured to have a cover, like the right side plate.

A spool shaft 5 is axially movably supported between the left and right frames 2a and 2b (left and right side plates 1A and 1B), and a fishing line is wound around the spool shaft 5 via left and right bearings 6a and 6b. A spool 7 to be turned is rotatably supported.

The spool 7 is rotatably driven by rotating a handle 10 mounted on the right side plate 1B. The handle 10 can be attached to and detached from the end of a handle shaft 11 projecting from the right side plate 1B. attached to the The handle shaft 11 is rotatably supported by the right cover 3b through bearings 11a and 11b, and is rotatably supported only in the fishing line winding direction by a one-way clutch 12 interposed between the bearings. When the spool 7 rotates in the reverse direction when the fishing line is reeled out, the rotation of the drag disc 7B, which will be described later, is stopped to enter a braking state.

A driving force transmission mechanism 15 for transmitting the rotational motion of the handle 10 to the spool 7 side is provided in the right side plate 1B. ing. Since the driving force transmission mechanism 15 and the gear transmission mechanism 16 are generally known, a detailed description thereof will be omitted. By pressing the button 18a, either the high-speed gear train or the low-speed gear train is selected and transmitted to the spool side.

In this case, the rotational driving force generated by rotating the handle 10 is transmitted to the spool 7 via, for example, a known lever drag mechanism 20 configured as follows.
The lever drag mechanism 20 of this embodiment consists of a friction plate 7A attached to a spool flange 7a on the handle side of the spool 7, and a drag disc 7B arranged opposite to the friction plate and in contact with the friction plate 7A. It has The drag disk 7B is fixed to a bearing member 21 mounted on the outer ring of the bearing 6c supported by the spool shaft 5. The bearing member 21 has a low-speed input gear 16a constituting the gear transmission mechanism 16. integrally connected. The low-speed input gear 16a is integrally connected with the high-speed input gear 16b that constitutes the gear transmission mechanism 16, and the bearing member 21 is provided with either the low-speed input gear 16a or the high-speed input gear 16b. Power is transmitted from (selected gear).

As described above, the spool shaft 5 is supported so as to be axially movable, and the position of the spool shaft 5 is restricted by the disc spring 23 disposed on the side of the bearing 6a on the side opposite to the handle. A coil spring 24 is arranged between the bearing 6b on the handle side and the bearing 6c, and always biases the spool 7 toward the side opposite to the handle via the bearing 6b.

The lever drag mechanism 20 has a rotatable lever 25 provided on the reel body so as to frictionally couple the friction plate 7A and the drag disk 7B. and a moving member (cam body) 27 which faces the cam surface 26A of the cam member 26 and moves in the axial direction by rotating the lever 25. The moving member 27 moves in the axial direction, the frictional force between the friction plate 7A and the drag disk 7B is adjusted, and the braking force applied to the spool 7 is adjusted.

Hereinafter, the configuration of the lever drag mechanism 20 that operates as described above will be described with reference to FIGS. 4 to 7 as well.
In these figures, FIG. 4 is a view showing the configuration of the cam member, (a) is a view seen from the spool side, (b) is a cross-sectional view along the CC line in FIG. (a), ( 5 is a perspective view of the cam member; FIG. 6 is a developed view of the cam surface of the cam member; and FIG. , (a) is a view from the spool side, (b) is a view from above, (c) is a cross-sectional view along line DD in FIG. (a), and (d) is a handle side It is the figure seen from.

As shown in FIG. 3, the lever 25 is positioned relative to the position indicated by the solid line (the position at which a drag force that does not cause line breakage even if a sudden load is applied to the fishing line; referred to as strike position SP). , A direction or B direction so as to be rotatable at a predetermined angle.
The braking force at this strike position SP can be arbitrarily adjusted by the angler by rotating the fine adjustment member (rotary knob 29) of the lever drag mechanism.

The cam member 26, as shown in FIGS. 4 and 5, is a substantially ring-shaped annular member having an inner peripheral portion 26B and an outer peripheral portion 26C, and is made of a metal material such as a stainless alloy or an aluminum alloy. there is A cylindrical support member 5d is disposed at the right end of the spool shaft 5, and the support member 5d is fixed to the inner periphery of the boss portion 1a of the reel body (right cover 3b) by insert molding. there is That is, the outer periphery of the support member 5d is fixed to the inner periphery of the boss portion 1a, and the spool shaft 5 is axially movably supported by the inner periphery of the support member 5d.

A collar 26D is attached to the outer periphery of the boss portion 1a. In this case, the collar 26D may or may not be rotatable with the boss 1a as long as the cam member 26 can rotate via the collar 26D. A circular inner peripheral opening that constitutes an inner peripheral portion 26B of the cam member 26 is held on the outer periphery of the collar 26D, and the collar 26D and the cam member 26 are in a rotatable relationship. Further, the outer peripheral portion 26C of the cam member 26 is formed to have a polygonal cross section, and the base portion of the lever 25 is fitted to this portion so as to prevent rotation. Therefore, when the lever 25 is operated to rotate, the cam member 26 also rotates integrally with the lever 25 .

The cam surface 26A is formed over 360 degrees on the annular surface of the cam member 26 on the handle side, and is formed to have a symmetrical shape within an arc range of 180 degrees.
That is, FIG. 6 is a developed view showing the cam shape within one 180° range of the cam surface 26A, and a similar cam shape is formed within the 180° range of the other cam surface 26A. (The shape of the cam surface 26A will be described later).

The moving member 27 is a ring-shaped member arranged axially outwardly of the cam member 26, and has a pair of projections on an inner surface 27A on the spool side so as to be pressed against the cam surface 26A of the cam member 26. 27a is formed. The outer peripheral portion 27B of the moving member 27 is press-fitted through an O-ring into the inner surface of a cylindrical portion 25d integrally formed with the base portion of the lever 25, and the inner peripheral portion 27C is formed to have a polygonal cross section. , and is fitted to the outer periphery of the support member 5d so as to be axially movable.

A cap-shaped rotary knob 29 is press-fitted on the outer surface of the cylindrical portion 25d with an O-ring interposed therebetween. A cylindrical portion 29 a having a female screw portion is formed in the central portion of the spool-side inner surface of the rotary knob 29 , and the rotary knob 29 is screwed to the end portion of the spool shaft 5 . As is well known, the rotary knob 29 has a function of finely adjusting the braking force, and is rotated to change the axial position of the spool shaft 5, thereby causing a drag force generated when the lever 25 is rotated. It is possible to change the adjustment range of

The moving member 27 is always urged toward the spool by a compression spring 29b disposed between the inner bottom surface of the rotary knob 29, and the projection 27a of the moving member 27 engages the cam surface 26A of the cam member 26. being pushed. Therefore, when the cam member 26 is integrally rotated by a rotating operation of the lever 25 (for example, rotating operation in the direction A for increasing the drag from the strike position indicated by the solid line in FIG. 3), the cam surface 26A and the moving member 27 are rotated. , the moving member 27 moves to the right in the axial direction and presses the inner bottom surface of the rotary knob 29 screwed to the end of the spool shaft 5 . That is, the spool shaft 5 is pulled toward the handle by the cam action of the cam surface 26A and the projection 27a, and the spool 7 also moves in the same direction (toward the handle) via the disc spring 23 and the bearing 6a. As the lever 25 rotates in the direction A, the surface contact force between the friction plate 7A and the drag disk 7B gradually increases. ), and the rotational driving force of the handle 10 is transmitted to the spool 7 via the driving force transmission mechanism 15 and the gear transmission mechanism 16 without slippage.

When the lever 25 is rotated in the direction B from the strike position in FIG. The biasing force of the spring 24 also moves the spool 7 to the side opposite to the handle, and the surface contact force between the friction plate 7A and the drag disk 7B gradually weakens, resulting in a weak braking state (weak drag). In this case, when the lever 25 is rotated to the frontmost side, the friction plate 7A and the drag disk 7B are separated from each other, and the spool 7 is in a free rotation state.

As described above, the braking force acting on the spool 7 is forced movement when the lever 25 is rotated in the A direction, and weak braking when the lever 25 is rotated in the B direction, in the braking region described later. In addition, when the light braking position is further rotated in the B direction, a releasing region in which the spool rotation is freed is reached via a non-moving region and a non-braking region, which will be described later.

The lever 25 may be provided with a sounding device 30 for generating a click sound when the lever 25 is rotated. The sound generating device 30 includes, for example, a sound generating member 31 mounted on a support portion 1a′ of the reel body 1 and having unevennesses 31a continuously formed on the outer peripheral surface along the circumferential direction, and a base portion of the lever 25 having the unevennesses 31a. and a sound producing member 35 that is elastically biased and engaged with the . The support portion 1a' is formed integrally with the right cover 3b, and has a cylindrical shape so that a bearing 5A for rotatably supporting the high-speed input gear 16b is press-fitted therein. For this reason, the sound generating member 31 is formed in a ring shape having a constant length in the axial direction so as to be mounted on the cylindrical support portion 1a'.
According to such a sounding device 30, when the lever 25 is rotated, the sounding member 35 is elastically biased against the projections and depressions 31a of the sounding member 31, thereby generating a click sound.

Next, the configuration of the cam surface 26A of the cam member 26 of the lever drag mechanism will be described.
As described above, as shown in FIGS. 4 and 5, the cam surface 26A is formed over 360 degrees on the annular surface of the cam member 26 on the handle side, and has a symmetrical shape within an arc range of 180 degrees. is formed to be The pair of protrusions 27a of the moving member 27 are in contact with each other in an arc range of 180°. is moved in the axial direction by the inclined surface shape of the cam surface 26A.

Here, the shape of the cam surface 26A will be described with reference to the developed views of FIGS. 4(c), 5 and 6. FIG. In addition, FIG. 6 shows the shape of the cam surface in one arc range, and since a similar cam surface is formed on the symmetrical side, the shape of the cam surface in one arc range will be described.

The cam surface 26A rotates as the lever 25 rotates, as described above. In this case, when the lever 25 is rotated in the A direction, the cam surface 26A moves to the left in FIG. 6, and when the lever 25 is rotated in the B direction, the cam surface 26A moves to the right in FIG. do.

The cam surface 26A has a braking area 26a for axially moving the moving member 27 by rotating the lever 25 to adjust the braking force of the spool. The braking area 26a is formed of an inclined surface that slopes along the circumferential direction, and is formed in a shape that gradually rises toward the front end (rotation stop position of the lever 25 in the direction A) P1. That is, in this braking region 26a, by rotating the lever 25, it is possible to adjust the braking force acting on the spool. The strike position SP is located within the braking area 26a, and by rotating the rotary knob 29, the position of the strike position SP can be finely adjusted.

In the braking region 26a, the cam surface 26A has an immovable region 26b that does not move the moving member 27 in the axial direction when the lever 25 is rotated over a certain range from the weakest braking position P2. is equipped with This immovable area 26b is formed of a flat surface (horizontal surface), and within this area, even if the lever 25 is rotated in the A direction and the B direction, the moving member 27 does not move in the axial direction. Therefore, the braking force (weak braking force) at the position P2 is maintained as it is. The immovable region 26b may be formed over a rotation angle of the lever 25 of about 9° to 12°.

The cam surface 26A has a non-braking area 26c over a certain range from a position P3 opposite to the position P2 of the immovable area 26b. This non-braking area 26c is an area where no braking force acts even if the lever 25 is rotated, and is configured in a shape in which the lever 25 is gradually lowered toward the rotation stop position P4 in the B direction. The non-braking area 26c is an area where no braking force acts on the spool even if the lever 25 is rotated in the direction (direction A) in which the braking force is applied to the spool. Even if 7B is in a contact state to some extent, it is formed with a steeper slope than the slope of the braking area 26a so that the contact state can be released immediately.

A region 26d that is the most recessed in the non-braking region 26c is a release region (free region) where the braking force of the spool is completely released. , the friction plate 7A and the drag disk 7B are completely separated from each other, and the spool is in a free rotating state.

According to the fishing reel configured as described above, in the braking area 26a, it is possible to arbitrarily adjust the braking force to the spool according to the position of the lever 25 rotated by the operator. In this case, when the lever 25 is rotated in the direction of releasing the braking force (direction B), the braking region 26a of the cam surface moves the moving member 27 in the axial direction, weakening the braking force, and the end portion of the braking region. A non-movable region 26b is provided over a predetermined range continuously from (the position P2 where the braking is weakest), where the moving member 27 is not moved in the axial direction (the braking force at the position P2 does not change).

In this non-movable region 26b, even if the lever 25 is rotated, the moving member 27 does not move (the braking force does not change), and when shifting to this non-movable region 26b, the cam surface changes abruptly. Further, even if the lever is rotated, the moving member 27 does not move (the braking force does not change and the weakest braking force is maintained). When rotating from the braking area 26a to the immovable area 26b, it is possible to grasp an appropriate sense of moderation. In addition, no great resistance is generated in the non-movable region 26b, and the movement continues to the release region 26d via the non-braking region 26c. It becomes possible. In addition, by providing the immovable area 26b, the lever 25 is prevented from moving to the release area 26d inadvertently, and a proper sense of moderation is produced, thereby smoothly releasing the braking force of the spool. becomes possible.

Furthermore, when the lever 25 is rotated from the release area 26d to the braking area 26a, the provision of the horizontal non-movable area 26b prevents the cam surface from abruptly changing its angle. It is possible to smoothly shift to the braking area 26a without causing a feeling of moderation that hinders operation.

In the above-described configuration, the resistance applying portion 26g that applies resistance to the turning operation of the lever 25 is located at the boundary position P3 (the end of the immovable area on the release area side) between the immovable area 26b and the non-braking area 26c. may be formed.
Such a resistance applying portion 26g can be constituted by a protrusion extending in the radial direction on the cam surface 26A of the cam member. can be increased, and furthermore, it is possible to more effectively prevent the lever 25 from inadvertently moving to the release area 26d.

In this case, the shape of the resistance applying portion 26g has a cross-sectionally symmetrical shape such as a semi-circular shape, a semi-elliptical shape, or a substantially trapezoidal shape so that the same click feeling can be obtained when turning in the A direction and turning in the B direction. It is preferable to form it into a shape. In addition, if the height of the resistance applying portion (projection) 26g is too high, the click feeling becomes too strong and the smooth rotation of the lever 25 is hindered. It is preferable to form it to 0.05 mm or less.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and can be modified as appropriate.
According to the present invention, when the lever 25 of the lever drag mechanism 20 for applying a braking force to the spool 7 is rotated, a cam surface is formed on the facing surface of the rotating member and the moving member axially facing each other. It suffices if the cam surface is provided with a region (non-movable region of the moving member 27) in which the braking force does not change even if the lever 25 is rotated within a certain range on the side of the non-braking region. In the above-described embodiment, the rotating member (cam member) 26 is formed with a cam surface. A region and a release region may be formed (a cam surface may be formed). Moreover, it is possible to appropriately modify other configurations. For example, the range of the braking area 26a and the non-braking area 26c of the cam surface 26A, the inclined state, etc. can be appropriately modified. In addition, the immovable region 26b only needs to maintain a state in which the moving member 27 is not moved (the braking force does not change), and its shape can be changed as appropriate.
