Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reciprocating device, and more particularly to a reciprocating device for a spinning reel which is provided on a spinning reel and reciprocates a spool with a rotating device of a handle. The present invention also relates to a spinning reel having the above-mentioned reciprocating device.

[0002]

2. Description of the Related Art Generally, a spinning reel has a reel body, a rotor rotatably supported by the reel body, and a spool around which fishing line is wound. The rotor has a pair of arm portions, and a bail that is openable and closable between a yarn winding posture and a yarn releasing posture is provided between both arm portions. Further, a line roller for guiding the fishing line, which is wound up when the line is wound, to the outer circumference of the spool is provided at the tip of one arm portion.

In such a spinning reel, there is provided a level winding mechanism for uniformly winding the fishing line guided by the bale and the line roller in the front-rear direction on the outer circumference of the spool. The level wind mechanism has a screw shaft arranged in parallel with a spool shaft to which a spool is fixed, a gear mechanism for rotating the screw shaft, and a slider sliding on the screw shaft. A spiral groove is formed on the outer circumference of the screw shaft, and a part of the slider is engaged with this groove. The slider is attached to the rear end of the spool shaft, and when the slider reciprocates along the screw shaft, the spool shaft and the spool also reciprocate. In this way, the fishing line is evenly wound around the outer circumference of the spool by reciprocating the spool in accordance with the rotating operation of the handle.

[0004]

In the conventional level wind mechanism, the screw shaft has 3.5 to 3.8 per one rotation of the handle.
Since it is rotating, the reciprocating speed of the spool is relatively high. Therefore, the fishing line is roughly wound around the spool in the front-back direction, and it is difficult to efficiently wind the fishing line. Therefore, the length of the fishing line that can be wound around the spool becomes short.

Therefore, the twist angle of the groove of the spiral shaft (the angle between the line orthogonal to the axis and the groove) is made small, that is, the spiral pitch of the spiral groove is made small to reduce the moving speed of the spool. It is possible. However, if the spiral pitch of the groove of the screw shaft is reduced, the number of intersections of the groove of the screw shaft increases, and the number of times a part of the slider (the cross gear pin as the engaging member) and the intersection contact each other increases. When the cross gear pin and the crossing portion of the groove come into contact with each other, vibration is generated, which causes a problem that the feel when the handle is rotated is not good.

An object of the present invention is to enable a fishing line to be efficiently wound around a spool without enlarging the reel body of the spinning reel. Another object of the present invention is to make it possible to efficiently wind a fishing line on a spool in a spinning reel. Another object of the present invention is to provide a spinning reel,
It is intended to enable the fishing line to be efficiently wound around the spool without deteriorating the feeling of rotation when the handle is rotated.

[0007]

A reciprocating device according to a first aspect of the present invention includes a rotor rotated by a rotating operation of a handle, a spool around which a fishing line guided by the rotation of the rotor is wound, and a center portion of the spool. Provided on a spinning reel having a fixed spool shaft,
A device for reciprocating the spool in accordance with a rotating operation of the handle, which has a screw shaft, a gear, a sliding member, and a guide shaft. The screw shaft is a rotatable shaft that is arranged along the spool shaft and has a spiral groove formed on the outer circumference. The gear is connected to the rotor and is provided for transmitting the rotational force from the handle to the screw shaft. The sliding member has a slider body that faces only one side of the outer circumference of the screw shaft, and an engaging member that is housed in the slider body and that engages with the spiral groove, and is fixed to the spool shaft in the axial direction. When the screw shaft rotates, the screw shaft reciprocates together with the spool shaft. The guide shaft is arranged along the spool shaft and serves to guide the reciprocating motion of the sliding member.

In this case, when the handle is rotated,
This rotational force is transmitted to the screw shaft via the gear. When the screw shaft rotates, the sliding member that engages with the spiral groove on the outer periphery of the screw shaft is
It reciprocates back and forth along the screw shaft. Since the sliding member is fixed in the axial direction with respect to the spool shaft, the reciprocating movement of the sliding member causes the spool shaft and the spool to reciprocate in the front-rear direction as well. As a result, the fishing line is evenly wound around the spool in the front-rear direction.

Since the guide shaft is provided here, the sliding member can be smoothly reciprocated. Therefore, it is not necessary for the sliding member to have a shape that covers the entire outer circumference of the screw shaft, and the reel member that covers the sliding member and the outer circumference thereof can be downsized. The reciprocating device according to the invention 2 is the invention 1
In the above device, the rotation speed ratio of the gear to the screw shaft is 1.5.
That is all. In this case, the gear is set so that the rotation speed ratio to the screw shaft is 1.5 or more. Therefore, the rotation speed of the screw shaft is lower than that of the conventional device, and the spool reciprocates at a relatively slow speed. Therefore, the fishing line is wound more densely around the spool, and the fishing line can be wound efficiently. Further, since it is not necessary to increase the twist angle of the groove of the screw shaft, the number of intersecting portions of the groove does not increase, and the deterioration of feeling when the handle is rotated can be avoided.

A reciprocating device according to a third aspect of the present invention is the device of the second aspect, further comprising a main gear fixed to the handle and meshing with the gear, and an intermediate gear fixed to the screw shaft and meshing with the gear. In this case, the rotation of the handle is once transmitted to the gear via the main gear fixed to the handle and further transmitted to the screw shaft via the intermediate gear meshing with the gear. Here, since the rotation speed ratio of the gear to the screw shaft is set to 1.5 or more without using a complicated structure such as a planetary gear, the structure is simplified.

The reciprocating device according to the invention 4 is the invention 1 to 3
In the device according to any one of 1 to 3, the rotation speed ratio of the gear to the screw shaft is 1.8 to 2.5. Here, the fishing line can be efficiently wound without increasing the size of the device. The reciprocating device according to the invention 5 is the invention 1 to 4
In the device described in any one of 1, the lead angle of the spiral groove formed on the screw shaft is 20 ° to 45 °. Here, it is possible to prevent the wall thickness between the grooves from becoming thin, suppress the increase in the number of intersecting portions of the grooves, and further, the conversion efficiency from rotation to linear motion does not decrease.

A spinning reel according to a sixth aspect of the present invention includes a reel body having a handle rotatably mounted thereon, a rotor having a thread guide portion which is rotated by the handle, and a reel body which is reciprocally movable in the front-rear direction. And a spool around which the fishing line fixed to the spool shaft and guided by the line guide portion is wound, and a reciprocating mechanism for reciprocating the spool shaft. And
The reciprocating mechanism has a screw shaft, a gear, a sliding member, and a guide shaft. The screw shaft is a rotatable shaft that is arranged along the spool shaft and has a spiral groove formed on the outer circumference. The gear is connected to the rotor and is provided for transmitting the rotational force from the handle to the screw shaft. The sliding member has a slider body that faces only one side of the outer circumference of the screw shaft, and an engaging member that is housed in the slider body and that engages with the spiral groove, and is fixed to the spool shaft in the axial direction. When the screw shaft rotates, the screw shaft reciprocates together with the spool shaft.

Here, as in the first aspect, since the guide shaft is provided, the sliding member can be smoothly reciprocated. Therefore, it is not necessary for the sliding member to have a shape that covers the entire outer circumference of the screw shaft, and the reel member that covers the sliding member and the outer circumference thereof can be downsized.

BEST MODE FOR CARRYING OUT THE INVENTION First Embodiment [Overall Structure and Structure of Reel Main Body] A spinning reel according to an embodiment of the present invention shown in FIGS.
The reel unit 2 includes a reel unit 2, a rotor 3 rotatably supported on the front unit of the reel unit 2, and a spool 4 arranged on the front unit of the rotor 3 for winding fishing line.

The reel body 2 has a body 2a,
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 level wind mechanism 6 has a screw shaft 21 arranged below the spool shaft 20, a slider 22 that moves in the front-rear direction along the screw shaft 21, and an intermediate gear 23 fixed to the tip of the screw shaft 21. is doing. The screw shaft 21 is the spool shaft 20.
Is arranged in parallel with and is rotatably supported by the body 2a. The spiral groove 2 is formed on the outer peripheral portion of the screw shaft 21.
1a is formed. The lead angle θ of this groove 21a is
It is set at 20-45 °. The lead angle θ of the spiral groove 21a means that, when the bottom diameter of the groove 21a is D and the axial length of the screw shaft 21 in one rotation, that is, the lead is L,
Lead angle θ is an angle represented by arc cot (πD / L). If the lead angle is smaller than 20 °, the wall thickness between the grooves becomes thin and the number of intersections of the grooves increases, which is not preferable. On the other hand, if the angle exceeds 45 °, the conversion efficiency from the rotary motion to the linear motion decreases, which is not preferable.

The rear end of the spool shaft 20 is fixed to the slider 22. The intermediate gear 23 meshes with the pinion gear 12. Here, the number of teeth of each of the pinion gear 12 and the intermediate gear 23 is set so that the rotation speed ratio of the pinion gear 12 to the screw shaft 21 is 1.5 or more, preferably 1.8 to 2.5. There is. If the rotation speed ratio is less than 1.5, it is not possible to improve the efficiency of winding the fishing line. Further, when the rotation speed ratio is 1.8 or more, the efficiency is remarkably improved, and when it exceeds 2.5, the diameter of the intermediate gear 23 becomes too large, which makes it difficult to downsize the reel unit 2.

[Structure of Slider] The slider 22 is
As shown in FIGS. 4 and 5, the slider main body 25 and the engaging member 26 housed in the slider main body 25 are included. 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. 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 of the slider body 25 is also not a perfect circle, but 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. Since the slider body 25 is guided by the two guide shafts 28 and 29, tilting 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. For this reason, 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. Therefore, the reel body can be made smaller. A lateral hole 25a is formed in the slider body 25 so as to be orthogonal to the screw shaft 21, and an engaging member 26 is slidably inserted into the hole 25a. The groove 2 of the screw shaft 21 is provided at the tip of the engaging member 26.
An engaging portion 26a that meshes with 1a is formed. The lid member 24 is fixed to one end of the hole 25 a of the slider body 25.

[Structure of Rotor] As shown in FIG. 1, the rotor 3 includes a cylindrical portion 30, and a first arm portion 31 and a second arm portion 32 which are provided laterally of the cylindrical portion 30 so as to face each other.
And have. The cylindrical portion 30 and both arm portions 31 and 32 are integrally formed. A front wall 33 is provided at the front of the cylindrical portion 30.
Is formed, 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 through hole is formed in the front portion 12 of the pinion gear 12.
a and the spool shaft 20 pass through. 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 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.

Further, 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 a single 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.

Further, as shown in FIGS. 6 and 7, the rear portion of the first arm portion 31 on the reel body side is deviated to the bale side of the yarn winding posture with respect to the rotation axis X. Then, from the central portion in the axial direction to the front side, the inclination is on the opposite side (the bail side in the yarn releasing posture). In this way, the rear portion is deviated to the bail side in the yarn winding posture, so that the bail 43 and the first arm are laid when the bail 43 is tilted to the yarn releasing posture side as shown by the alternate long and short dash line in FIG. Interference with the part 31 is reduced. Further, it is possible to suppress the imbalance during rotation due to the first bail support member 40, the line roller, and the like. On the other hand, the second arm portion 32, as shown in FIG.
The whole extends in a substantially straight line. Furthermore, the first and second
The swing centers of the bail support members 40 and 42 are deviated from the rotation axis X to the bail side in the yarn releasing posture by D. As a result, unbalance during rotation due to the bail 43 can be suppressed.

Here, the mounting portion of the second bail support member 42 will be described in detail. The tip inner side surface 32 a to which the second bail support member 42 of the second arm portion 32 is attached is open outward with respect to the rotation axis X. Then, the second bail support member 42 and the tip inner surface 32 a of the second arm portion 32.
A spacer 46 made of resin is disposed between and.
A collar portion 46a is integrally formed on one end side of the spacer 46, and the collar portion 46a supports the swing shaft portion of the second bail support member 42. An E-shaped retaining ring 47 is attached to the tip of the swing shaft of the second bail support member 42 to prevent it from coming off. In this way, since the resin spacer 46 is provided and the inner side surface 32a at the tip of the second arm portion 32 is formed so as to open outward, it is easy to form a mold for forming the rotor 3. Further, since the swing shaft of the second bail support member 42 is supported by the collar portion 46a made of resin, vibration is absorbed or damped by the collar portion 46a. This effect is particularly remarkable when the rotor is made of aluminum.

[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. Flange plate 4
c is made of a stainless steel plate material, and is attached to the bobbin trunk 4a by 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 to the line releasing posture side. As a result, the first and second bail support members 40 and 42 are moved to the swing axis M.
Rotate in the same direction around. At this time, the first bail support member 40 is disposed on the inner peripheral side of the first arm portion 31,
Further, since the swing shaft M is inclined with respect to the rotation axis X as shown in FIG. 1, the first bail support member 40 and the line roller 41 at the tip thereof are further on the inner peripheral side than the position in the line winding posture. Move to. For this reason, the fishing line delivered at the time of casting is less likely to be entangled with the first bail support member 40 and the line roller 41. In addition, the swing axis M is the rotation axis X.
Although tilted with respect to, the bail support members 40 and 42 rotate about one swing axis M, and the respective rotation surfaces are perpendicular to the swing axis M. Therefore, the veil 43
When operating the, you can operate 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 fishing line guided by the bail 45 and the line roller 41 to the spool 4 is evenly distributed in the front-rear direction on the outer periphery of the spool 4. Being rolled up. here,
The rotation speed ratio of the pinion gear 12 to the screw shaft 21 is 1.5.
As described above, the moving speed of the spool 4 can be made lower than that of the conventional device, and the efficiency in winding the fishing line can be improved. Also, a large amount of fishing line can be wound.

The slider 22 has 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. Therefore, with respect to the rear portion of the reel unit 2, the lateral protrusion can be reduced.

[Unbalance during rotor rotation]
When the rotor 3 rotates, an imbalance during rotation tends to occur due to members such as the bail 43. Therefore, in this embodiment, in order to eliminate the imbalance caused by the bail support members 40, 42, the line roller 41, and the bail 43, the rear end portions of both arm portions 31, 32 are deviated to the bale side in the line winding posture. And each bail support member 40, 4
2 is arranged so that its swing shaft is displaced with respect to the rotation axis X toward the bail side in the yarn releasing posture. Further, the imbalance caused by the line roller 41 is suppressed by disposing the second bail support member 42 on the front side of the first bail support member 40. In addition, it is possible to function as a balancer by constructing the second bail support member with a heavy material having a higher specific gravity than other members.

Second Embodiment In the first embodiment, the spinning reel of the type in which the drag mechanism is provided at the front portion of the spool 4 has been described. However, in the reel of the second embodiment shown in FIGS. 8 and 9. A 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
The configuration is shown in.

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. Further, the slider body 25 is slidable on a guide shaft 28 arranged in parallel with the spool shaft 20.

Also in this embodiment, since the slider main body 25 is guided by the guide shaft 28, inclination during sliding is prevented. Therefore, similarly to the above, it is not necessary to form the slider main body 25 into a shape that covers the entire circumference of the screw shaft, and the reel main body can be made smaller. 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.
It is composed of a cylindrical bush 81, a friction engagement portion 82 composed of a plurality of friction plates, 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.

[0036]

As described above, in the spinning reel and the reciprocating device thereof according to the first and sixth aspects, since the guide shaft for guiding the reciprocating motion of the sliding member is provided, the sliding member can be smoothly moved. It can be reciprocated. Therefore, it is not necessary to form the sliding member into a shape that covers the entire outer circumference of the screw shaft, and the reel body that covers the sliding member and the outer circumference thereof can be downsized.

In the reciprocating device of the spinning reel according to the second aspect of the present invention, since the rotation speed ratio of the gear rotated by the rotation operation of the handle to the screw shaft is 1.5 or more, the rotation speed of the screw shaft with respect to the rotation operation of the handle. Is lower than the conventional device. Therefore, the spool reciprocates at a relatively slow speed, the fishing line is wound more densely on the outer circumference of the spool, and a large amount of fishing line can be efficiently wound up.
Further, since it is not necessary to increase the twist angle of the groove of the screw shaft, the number of intersecting portions of the groove does not increase, and the deterioration of feeling when the handle is rotated can be avoided.

In the spinning reel reciprocating device according to the third aspect, the rotation of the handle is transmitted to the screw shaft via the main gear, the gear and the intermediate gear. That is, since the rotation speed ratio of the gear to the screw shaft is set to 1.5 or more without using a complicated structure such as a planetary gear, the structure is simplified. In the reciprocating device of the spinning reel according to the fourth aspect of the present invention, since the rotation speed ratio of the gear to the screw shaft is 1.8 to 2.5,
The fishing line can be efficiently wound without increasing the size of the device.

In the reciprocating device of the spinning reel according to the invention 5, since the lead angle of the spiral groove formed on the screw shaft is 20 ° to 45 °, the wall thickness between the grooves becomes thin and the grooves intersect. The increase in the number of parts can be suppressed, and the conversion efficiency from rotation to linear motion does not decrease.
