Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a level winding device, and more particularly, to a level winding device for a spinning reel which is provided on a spinning reel and uniformly winds a fishing line on a spool.

[0002]

2. Description of the Related Art Generally, a spinning reel is provided with a level wind mechanism for uniformly winding a fishing line on a spool. In the spinning reel, the fishing line guided by the bail and the line roller is evenly wound in the front-rear direction around the spool by reciprocating the spool in the axial direction by rotating the handle.

In such a level winding mechanism, a screw shaft arranged parallel to the spool shaft, a gear mechanism for rotating the screw shaft in association with the rotation of the handle or the rotation of the spool, and the screw shaft slide. And a slider that operates. Spiral intersecting grooves are formed on the outer circumference of the screw shaft. The slider has an engaging member that engages with the spiral groove. The engaging member is slidably inserted into a mounting hole formed in the slider at a right angle to the screw shaft.

This engaging member is a substantially rod-shaped member,
An engaging portion that engages with the spiral groove is formed at the tip thereof. The entire length of the engaging member along the radial direction of the screw shaft is longer than the engaging length in the engaging direction along the spiral groove. Since the engaging member is supported so that the tip of the engaging portion contacts or can contact the screw shaft, a force for inclining the engaging member acts on the engaging member. However, by making the overall length longer than the engagement length as described above, the length of the support portion becomes longer, and the inclination of the engagement member can be prevented even if a force for inclining acts on the engagement member. It

In this level wind mechanism, the engaging member engages with the spiral groove of the screw shaft rotated by the rotating operation of the handle, and the slider reciprocates along the screw shaft,
The spool also reciprocates similarly. In this way, by reciprocating the spool or the fishing line guide in accordance with the rotating operation of the handle, the fishing line is evenly wound around the outer circumference of the spool.

[0006]

SUMMARY OF THE INVENTION In the above conventional configuration,
Since the entire length of the engaging member is longer than the engaging length, the dimension of the slider in the longitudinal direction of the engaging member becomes large. In a spinning reel, since the engaging members are normally arranged laterally, the larger the slider size, the larger the left and right width of the reel body. As described above, the structure of the conventional engagement member increases the length of the reel unit, which is an obstacle to making the reel unit compact and lightweight.

An object of the present invention is to make the reel unit compact and lightweight.

[0008]

A level reel device for a spinning reel according to a first aspect of the present invention is provided on a spinning reel for winding fishing line on a spool, and reciprocates a spool shaft fixed to the center of the spool by rotating a handle. An apparatus for uniformly winding fishing line on a spool, which includes a screw shaft, a transmission member, and a sliding member. The screw shaft is a rotatable shaft that is arranged along the spool shaft and has spiral grooves that intersect each other on the outer circumference. The transmission member is a member for transmitting the rotational force from the handle to the screw shaft. The sliding member is arranged along the radial direction of the screw shaft so that the tip of the sliding member engages with the spiral groove, and the entire length of the sliding member along the radial direction of the screw shaft engages in the engaging direction along the spiral groove. An engagement member having a length shorter than the length and a mounting hole along the radial direction of the screw shaft are formed, and a movement restricting portion for restricting the movement of the engagement member toward the screw shaft is formed at an end of the mounting hole on the screw shaft side. Is formed, the engaging member is rotatably inserted into the mounting hole to rotatably support the engaging member while restricting the radial movement of the screw shaft of the engaging member, and to the spool shaft. It is a member that has a sliding portion main body that is fixed in the axial direction and that reciprocates together with the spool shaft when the screw shaft rotates.

In the device having such a structure, when the handle is rotated, the rotational force is transmitted to the screw shaft by the transmission member, and the screw shaft is rotated. When the screw shaft rotates, the sliding member reciprocates by the engaging member engaged with the spiral groove. At this time,
Since the sliding member main body restricts the movement of the screw shaft in the radial direction, the engaging member always engages with the spiral groove at a constant interval. Moreover, since it is rotatably supported, the sliding member reciprocates while rotating by the engagement with the spiral groove. When the sliding member reciprocates, the spool reciprocates in association with the rotation of the handle, and the fishing line is wound around the spool almost uniformly. Since the entire length of the engaging member is shorter than the engaging length, the overall length of the engaging member along the radial direction of the screw shaft is reduced, and the reel body can be made compact and lightweight. Further, the engaging member can be rotatably supported on the sliding portion main body simply by inserting the engaging member into the mounting hole. Furthermore,
Since the movement of the engaging member to the screw shaft side is restricted, the engaging member is less likely to be deeply meshed with the screw shaft and the engaging member is tilted or bent.

A level winding mechanism for a spinning reel according to a second aspect of the present invention is the mechanism according to the first aspect, further comprising a guide member arranged along the spool shaft for guiding the sliding member in the moving direction. The moving part body has a facing part that faces only a part of the outer circumference of the screw shaft. In this case, since the guide shaft is provided, the sliding member can be smoothly reciprocated. Therefore, the sliding member does not have to cover the entire outer circumference of the screw shaft, and the reel body covering the sliding member and the outer circumference thereof can be made more compact.

A level winding mechanism for a spinning reel according to a third aspect of the present invention is the device according to the first or second aspect, further including a biasing member that biases the engaging member toward the screw shaft. In this case, since the engaging member is always biased toward the screw shaft,
The distance between the screw shaft and the engaging member is always kept constant.

According to a fourth aspect of the present invention, there is provided a spinning reel level wind device according to any one of the first to third aspects , wherein the movement restricting portion has an end on the screw shaft side of the mounting hole.
And a smaller diameter flange that is smaller than the other part of the mounting hole.
And the engaging member is longer than the inner diameter of the small diameter flange at the tip.
Is formed short, and the engaging part that meshes with the spiral groove,
Is formed with a diameter larger than the inner diameter of the small-diameter collar, and abuts on the small-diameter collar.
And the base end that is restricted from moving to the screw shaft side by
And a shaft portion having a diameter smaller than the inner diameter of the small diameter flange portion .

A spinning reel level winding device according to a fifth aspect of the present invention is the device according to the fourth aspect, wherein the entire length of the engaging member along the radial direction of the screw shaft is shorter than the diameter of the flange portion.

An attachment portion 2b for attaching the spinning reel to the fishing rod is formed on the upper portion thereof. A rotor drive mechanism 5 for rotating the rotor 3 is provided inside the body 2a.
And a level wind mechanism 6 for moving the spool 4 in the front-rear direction along the axis of rotation X to wind the fishing line evenly on the spool 4.

The rotor drive mechanism 5 has a face gear 11 that rotates together with the shaft 10 to which the handle 1 is fixed, and a pinion gear 12 that meshes with the face gear 11. The pinion gear 12 is formed in a tubular shape, and its front portion 12 a penetrates the central portion of the rotor 3 and the spool 4
Extending to the side. A threaded portion is formed at the tip thereof. The pinion gear 12 is rotatably supported by the reel body 2 at the intermediate portion and the rear end portion in the axial direction via bearings 13 and 14, respectively.

The level wind mechanism 6 is a mechanism for moving the spool 4 in the same direction by moving the spool shaft 20 fixed to the center of the spool 4 in the front-back direction.

The screw shaft 21 is arranged in parallel with the spool shaft 20, and is rotatably supported by the body 2a. A spiral crossing groove 21 a is formed on the outer peripheral portion of the screw shaft 21. The lead angle θ of the groove 21a is set to 20 to 45 °.

The rear end of the spool shaft 20 is fixed to the slider 22. The intermediate gear 23 is the pinion gear 1
It meshes with 2. [Slider Structure] Slider 22
As shown in FIG. 4, has a slider body 25 and an engaging member 26 housed in the slider body 25.

The slider body 25 is fixed to the spool shaft 20 immovably in the axial direction and is slidably mounted on two guide shafts 28 and 29 arranged in parallel with the spool shaft 20. There is. A notch 20a is formed in a portion of the spool shaft 20 that fits with the slider body 25, and a part of the outer circumference is flat. And
The corresponding hole in the slider body 25 is not a perfect circle,
It has a flat portion corresponding to the notch 20a. Due to such fitting, relative rotation of the slider body 25 with respect to the spool shaft 20 is prohibited. Slider body 25
Is guided by the two guide shafts 28 and 29, so inclination during sliding is prevented. Therefore, unlike the conventional slider body, the slider body 25 does not need to have a shape that covers the entire circumference of the screw shaft. Therefore, the slider body 25 of the present embodiment is shaped so as to face only one side surface side of the screw shaft 21, and the protrusion to the other side surface side is reduced.

Further, a lateral mounting hole 25a is formed in the slider body 25 so as to be orthogonal to the screw shaft 21,
The engaging member 26 is rotatably inserted into the mounting hole 25a. A small-diameter collar portion 25b having a smaller diameter than the other portions is formed at the tip of the mounting hole 25a. An engaging portion 26a that engages with the groove 21a of the screw shaft 21 is formed at the tip of the engaging member 26. Engaging portion 26a is shorter in length than the inner diameter of the small diameter flange portion 25b. A small-diameter collar portion 25 is provided in the middle of the engaging member 26.
A collar portion 26b having a diameter larger than the inner diameter of b is provided at the base end.
Shafts 26c each having a diameter smaller than the inner diameter of the shaft are formed. With such a configuration, the movement of the engaging member 26 toward the screw shaft 21 side is restricted. As shown in FIG. 5, the overall length A of the engaging member 26 along the mounting hole 25a is shorter than the engaging length B along the groove 21a (A ≦ B). Therefore, the lateral length of the slider body 25 can be shortened. In addition to this, since the protrusion to the other side surface is reduced, the width of the reel body 2 can be made smaller. It is possible to make the reel unit 2 compact and lightweight.

At one end of the hole 25a of the slider body 25,
The lid member 24 is fixed. Lid member 24 and engaging member 2
A coil spring 27 is arranged in a compressed state between the flange portion 26 b of No. 6 and the collar portion 26 b of No. 6. The engagement member 26 is biased toward the screw shaft 21 by the coil spring 27. The urging engagement member 26 is restricted from moving toward the screw shaft 21 by the small-diameter collar portion 25b coming into contact with the collar portion 26b. Therefore, the distance between the engaging member 26 and the screw shaft 21 is always kept constant, and the reciprocating movement of the slider 22 becomes smooth.

[Structure of Rotor] As shown in FIG. 1, the rotor 3 includes a cylindrical portion 30 and a first arm portion 3 provided laterally opposite the cylindrical portion 30.
It has a first arm portion 32 and a second arm portion 32. The cylindrical portion 30 and both arm portions 31 and 32 are integrally formed. A front wall 33 is formed at the front of the cylindrical portion 30, and a boss 33a is formed at the center of the front wall 33. A through hole is formed in the center of the boss 33a, and the front portion 12a of the pinion gear 12 and the spool shaft 20 pass through the through hole. A nut 34 is arranged on the front side of the front wall 33, and the nut 34 is screwed into the threaded end portion of the pinion gear 12. A bearing 35 that rotatably supports the spool shaft 20 is disposed on the inner peripheral portion of the nut 34.

A first bail support member 40 is swingably attached to the inner peripheral side of the tip end of the first arm portion 31. A line roller 41 for guiding the fishing line to the spool 4 is attached to the tip of the first bail support member 40. A second bail support member 42 is swingably attached to the inner peripheral side of the tip of the second arm portion 32. The second bail support member 42 is made of, for example, a material having a larger specific gravity than other parts, and functions as a balancer for eliminating an unbalance during rotation caused by the first bail support member 40 and the line roller 41. Is also possible. A bail 43 is provided between the line roller 41 at the tip of the first bail support member 40 and the second bail support member 42. As described above, by mounting the first bail support member 40 on the inner peripheral side of the first arm portion 31, the turning radius of the first bail support member 40 becomes small, and it becomes difficult for the fishing rod to hold the fishing rod. Therefore, the spool and the fishing rod can be brought close to each other, and the overall size can be reduced. Further, for the same reason, the radius of gyration becomes smaller, and it becomes easier to suppress the imbalance during rotation.

Covers 44 and 45 are attached to the outer peripheral sides of the arm portions 31 and 32, respectively. The surfaces of the covers 44 and 45 are smoothly continuous in the front-rear direction and in the circumferential direction, so that the fishing line can be prevented from being caught. Here, both bail support members 4
0 and 42 are swingable around one swing shaft M.
The intersection of the swing axis M and the first bail support member mounting surface of the first arm portion 31 is defined as the swing center C1, and the swing axis M and the second bail support member mounting surface of the second arm portion 32. When the point where and intersect is the swing center C2, the swing center C2 is located on the front side compared to the swing center C1. That is, the swing shaft M is inclined with respect to the rotation axis X. Further, the bail support members 40, 42 are arranged such that their swing surfaces are orthogonal to the swing axis M.

[Structure of Spool] The spool 4 is arranged between the first arm portion 31 and the second arm portion 32 of the rotor 3, and is attached to the tip of the spool shaft 20 via the drag mechanism 70. There is. The spool 4 has a bobbin trunk 4a on which the fishing line on the outer periphery is wound, a skirt 4b integrally formed at the rear of the bobbin trunk 4a, and a flange plate 4c fixed to the front end of the bobbin trunk 4a. ing. The flange plate 4c is formed of a stainless steel plate material, and is attached to the bobbin trunk 4a with a screw. At this time, the flange plate 4c is slightly curved, and the spring property of the curvature is utilized to attach the flange plate 4c so that no gap is formed between the front end of the bobbin trunk 4a and the flange plate 4c. Therefore, the fishing line does not enter between them.

The drag mechanism 70 includes a pressing member 71 pressed against the inner front end surface of the spool 4, an adjusting knob 72 for adjusting the drag force, and a pressing spring arranged between the pressing member 71 and the adjusting knob 72. 73,74
And a plurality of clutch plates 75 arranged between the pressing member 71 and the spool 4. With such a configuration, by adjusting the tightening amount of the adjusting knob 72, the pressing force of the pressing member 71 against the spool 4 can be adjusted, and the drag force can be adjusted.

[Reel Operation and Operation] At the time of casting, the bail 43 is tilted toward the line releasing posture. Thereby, the first and second bail support members 40, 4
2 rotates about the swing axis M in the same direction. At this time, the first bail support member 40 is disposed on the inner peripheral side of the first arm portion 31, and the swing shaft M is arranged with respect to the rotation axis X in FIG.
The first bail support member 40 is inclined as shown in FIG.
Also, the line roller 41 at the tip of the line moves further to the inner peripheral side than the position in the line winding posture. For this reason, the fishing line fed out at the time of casting will be
0 and the line roller 41 are less likely to be entangled. Further, although the swing shaft M is tilted with respect to the rotation axis X, both the bail support members 40 and 42 rotate about one swing shaft M, and the respective rotation surfaces are the swing shaft M. Perpendicular to. Therefore, when operating the bail 43, the bail 43 can be operated smoothly without twisting.

At the time of winding the fishing line, the bail 43 is tilted to the line winding posture side. When the handle 1 is rotated in this state, this rotational force is transmitted to the pinion gear 12 via the handle shaft and the face gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the pinion gear front portion 12a. On the other hand, the pinion gear 12
The screw shaft 21 is rotated by the intermediate gear 23 that meshes with the slider 22, and the slider 22 that meshes with the groove 21a of the screw shaft 21 is guided by the guide shafts 28 and 29 to move in the front-rear direction. Therefore, the spool shaft 20 and the spool 4 reciprocate in the front-rear direction along the rotation axis X, and the bail 45 and the line roller 4
The fishing line guided to the spool 4 by 1 is evenly wound around the outer periphery of the spool 4 in the front-rear direction.

Here, the slider 22 is composed of two guide shafts 2.
Since it reciprocates by being guided by 8, 29, it smoothly reciprocates without rotating or tilting. Therefore, the slider body 25 does not need to cover the entire circumference of the screw shaft 21, and the space on the side opposite to the engaging member 26 can be reduced.
Moreover, since the lateral length of the engaging member 26 is short, the space on the engaging member 26 side can be reduced. Therefore, the rear portion of the reel unit 2 can be reduced in length in the lateral direction, and the reel unit 2 can be made compact and lightweight.

Second Embodiment In the first embodiment, the spinning reel of the type in which the drag mechanism is provided in the front portion of the spool 4 has been described. However, in the second embodiment shown in FIGS. 6 and 7. In the reel, the drag mechanism is provided behind the reel. Also in this rear drag type spinning reel, the configuration of the slider portion is almost the same as that of the above-described embodiment, and FIG. 7 shows the configuration.

In the figure, parts corresponding to the components of the first embodiment are designated by the same reference numerals. In this rear drag type, the tip of the spool shaft 20 is fixed to the spool 4 by a pin 79 so as not to rotate relative to the spool 4. Further, in this type of spinning reel, the spool shaft 20 and the slider body 25 must be relatively immovable in the axial direction and relatively rotatable. Therefore, the portion of the slider body 25 mounted on the spool shaft 20 is circular unlike the first embodiment. In addition, the slider body 25 includes the spool shaft 20.
It is slidable on a guide shaft 28 arranged in parallel with.

Also in this embodiment, as shown in FIG. 7, since the slider main body 25 is guided by the guide shaft 28, inclination during sliding is prevented. Further, the entire length of the engaging member 26 is shorter than the engaging length. Therefore, similarly to the above, it is not necessary to form the slider body 25 into a shape that covers the entire circumference of the screw shaft, and the lateral length of the slider body 25 is shortened, so that the reel body 2 can be made smaller. is there.

Next, a portion different from the first embodiment, that is, a rear drag mechanism portion will be described. The rear drag mechanism 80 shown in FIG. 6 mainly includes a cylindrical bush 81,
A friction engagement portion 82 composed of a plurality of friction plates,
It is composed of a spring 83 for pressing the friction engagement portion 82, a support member 84, and a fixed cap 85. The bush 81 has a flange, and a plurality of friction plates forming the friction engagement portion 82 are pressed against the flange. The fixed cap 85 is screwed from the outer peripheral side to a screw portion provided on a part of the reel body 2 so as to extend rearward, and positions the support member 84 at a predetermined position. By adjusting the tightening amount of the fixed cap 85, the pressing force of each friction plate of the friction engagement portion 82 can be changed and the drag force can be adjusted.

The other structure is basically the same as that of the first embodiment. Other Embodiments As shown in FIG. 8, the coil spring 27 that biases the engaging member 26 may not be provided. In this case, the engaging member 26
Engages deeply with the screw shaft 21, and the engaging member 26 tilts,
It is hard to get angry.
