Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-bearing type fishing reel improved so that the urging force of the urging member to which the urging force is urged by the dead point action is strongly exerted when the operating member is operated. About

[0002]

2. Description of the Related Art Conventionally, a dual-bearing reel for fishing has a spool shaft provided with a spool rotatably supported on a reel body.
The fishing line is wound around the spool by rotating the spool shaft in conjunction with the rotation of the handle, and a clutch mechanism is provided for switching the spool between a fishing line releasing state and a fishing line winding state. The configuration is known. The clutch mechanism is normally distributed and held between a fishing line releasing state position and a fishing line winding position by a dead point action of a distribution spring or the like.

However, in the conventional distribution spring, the operating angle of the spring is determined by the operating range of the clutch. Therefore, if the operating range of the clutch is shortened to improve operability, the distribution force of the spring is reduced. ,
The clutch may return erroneously when the handle is rotated by the inertia moment generated during casting. If the spring force of the distribution spring is increased to prevent the erroneous return due to the rotation of the handle, it becomes difficult to deform and incorporate the spring at the time of assembling, and the productivity is reduced. And other problems have been pointed out.

[0004]

The problem to be solved is that when the clutch mechanism is distributed and held between the fishing line releasing state position and the fishing line winding position by the action of the dead point of the distribution spring or the like, the distribution force by the spring is small. When,
The clutch may return erroneously when the handle rotates due to the moment of inertia generated at the time of casting, and if the spring force of the distribution spring is increased, it will be difficult to incorporate the spring by deforming the spring at the time of assembling. There is a problem such as lowering.

An object of the present invention is to provide a double-bearing reel for fishing which can act reliably even with a small distributing force and reliably prevent erroneous return in view of the above disadvantages.

[0006]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention according to claim 1 is a fishing line winding drive for winding a fishing line around a spool rotatably supported on a reel body. A mechanism is provided, and in order to switch the spool between the fishing line releasing state and the fishing line winding state, a clutch operating body is operated by operating an external operating member provided on the reel body, and the fishing line winding drive mechanism and the fishing line winding drive mechanism. In a fishing reel provided with a clutch mechanism for engaging and disengaging a spool, the clutch operating body mounted between the clutch operating body and the reel body is moved to a fishing line releasing position and a fishing line winding position, respectively. The gist of the invention is to provide a moving guide portion for displacing the supporting end of the urging member to be urged on either the clutch operating body side or the reel body side.

[0007]

According to the first aspect of the present invention, the support end 6a of the biasing member 6 is displaced in the moving guides 3f, 3h while shortening the operating range of the clutch and improving operability. By doing so, the distance between the dead point line a and the support end 6a can be widened, so that the clutch operating bodies 3, 3 'can be reliably distributed, so that when the steering wheel is rotated by inertial moment generated during casting. Since the support end 6a does not easily cross the dead point line a, erroneous return of the clutch can be prevented, and a clutch operation with a sense of moderation becomes possible. The biasing member 6 having a small spring force can provide a large distribution force, and can reliably distribute and hold the clutch operating bodies 3 and 3 'without increasing the spring force of the biasing member 6. Therefore, the biasing member 6 is incorporated. At times, it is easy to deform and incorporate the biasing member 6, and the productivity is improved.

One end 7a faces the rotation area of the kick pin 22 of the ratchet 21 and the other end 7b operates the clutch. The clutch switching pin 23 of the body 3 is exposed.

The operation of the dual-bearing reel for fishing is explained by the following description. The engaging portion 2b of the spool shaft 2 and the engaging portion 4 of the pinion 4 shown in FIGS.
a in the clutch-on fishing line winding state with the engaged
When the handle 28 is rotated in the direction in which the fishing line is wound around the reel 16, the pinion 4 is rotated by the drive gear 27 to
The fishing line is wound around the reel 16. Next, the thumb is held on the operation surface 5 of the clutch switching operation member 5 in the fishing line winding state with the clutch on.
When the operation surface 5c is pressed and placed on the clutch c, the clutch lever-3b of the clutch operating body 3 is rotated downward as shown in FIG. 6, and the fishing line is released with the clutch off. By this turning operation, the pair of clutch cams 3c formed on the end face of the annular portion 3a is turned, and the clutch plate 20 is pushed up. When the clutch plate 20 is pushed up, the pinion 4 moves to disengage the engaging portion 2b of the spool shaft 2 from the engaging portion 4a of the pinion 4, and the fishing line is released with the clutch off as shown in FIG. Thus, the spool 16 can freely rotate.

Next, when the handle 29 is rotated in the direction in which the fishing line is wound around the spool 16, the drive gear 27 is rotated and the ratchet wheel 21 is rotated, and the kick pin 22 is moved to one end 7a of the kick lever 7. The kick lever 7 is rotated counterclockwise in FIG. With this rotation, kick lever
The other end 7b of 7 is brought into contact with a clutch switching pin 23 implanted on the end face of the annular portion 3a of the clutch operating body 3, and the annular portion 3a is rotated. Since the pair of clutch cams 3c is disengaged from the position of the clutch plate 20 by the rotation of the annular portion 3a of the clutch operating body 3, the pinion 4 moves to engage the engagement portion 2b of the spool shaft 2 with the pinion 4. The engaging portion 4a is engaged, and the fishing line is wound in the clutch-on state, and the spool 16 is rotated by the rotation of the handle 29.

In the winding state of the fishing line shown in FIG. 3, one supporting end 6a of the urging member 6 formed of a dead point spring is located on the right side of the moving guide 3f, and the fishing line is released in the clutch off state shown in FIG. Thus, one supporting end 6a of the urging member 6 formed of a dead point spring is located on the left side of the moving guide 3f. One of the supporting end portions 6a in a clutch line winding state in which the clutch is on and a fishing line release state in which the clutch is off.
Is displaceable from right to left, and after switching of one support end 6a from a dead point line a connecting the center of the spool shaft 2 and the other support end 6b of the urging member 6 formed of a dead point spring. Since each position is farther than in the conventional example in which no displacement occurs, a large distribution force can be obtained with the biasing member 6 having a small distribution force.

When the dual-bearing reel for fishing is constructed as described above, the support end 6a of the biasing member 6 is moved by the movement guide while shortening the operating range of the clutch and improving operability. 3
Since the distance between the dead point line a and the support end 6a can be increased by displacing in the range f, the clutch operating body 3 can be reliably distributed, and the handle is rotated by inertia moment generated during casting. When the support end 6
Since a does not easily exceed the dead point line a, erroneous return of the clutch can be prevented, and a modest operation of the clutch is possible. A large distributing force can be obtained with the biasing member 6 having a small spring force, and the clutch operating body 3 can be reliably distributed and held without increasing the spring force of the biasing member 6. The member 6 can be easily deformed and incorporated, and productivity is improved.

The operation of the double-bearing reel for fishing according to the second embodiment is as follows: the engaging portion 2b of the spool shaft 2 and the engaging portion 4 of the pinion 4.
When the handle 29 is rotated in the clutch-on winding state with the clutch a engaged, the pinion 4 and the spool shaft 2 are rotated by the drive gear 27, and the fishing line 17 is wound on the spool 16. At this time, when the drive gear 27 and the ratchet wheel 21 are rotated clockwise in FIG. 9, the friction between the ratchet wheel 21 and the spring plates 35, 35 causes the spring plates 35, 35 and the reverse locking pawl 36 to rotate counterclockwise. The tip of the reverse rotation locking claw 36 is moved away from the locking teeth of the ratchet 21, and the ratchet 21 is rotated integrally with the drive gear 27.

[0031]

The present invention is embodied in the form described above and has the following effects.

According to the first aspect, the support end of the urging member is displaced in the moving guide portion while shortening the operating range of the clutch to improve the operability. Since the spacing can be widened, the clutch actuating bodies can be reliably distributed, so that when the handle rotates due to the inertial moment generated during casting, the support end does not easily cross the dead point line, preventing erroneous return of the clutch. Thus, a modest clutch operation is possible.
A large distribution force can be obtained with a biasing member with a small spring force,
Since the clutch operating body can be reliably distributed and held without increasing the spring force of the urging member, the urging member can be easily deformed and incorporated when the urging member is incorporated, thereby improving productivity.
