Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel, and more particularly, to a spinning reel that winds a fishing line on a spool by a rotor mounted on a fishing rod and rotating in conjunction with rotation of a handle.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body, a rotor rotatably supported by the reel body, and a spool disposed in front of the rotor and around which the fishing line is wound. The rotor has a pair of arm portions, and a bale is provided between the two arm portions so as to be openable and closable between a yarn winding posture and a yarn releasing posture. Further, a line roller for guiding the fishing line wound at the time of winding the line to the outer periphery of the spool is provided at one end of the arm portion.

[0003] In such a spinning reel, a level wind mechanism for uniformly winding the fishing line guided by a bail and a line roller in the front-rear direction around the spool is provided. The level wind mechanism includes a screw shaft disposed obliquely below the spool shaft to which the spool is fixed, in parallel with the spool shaft, an intermediate gear for rotating the screw shaft, and a slider that slides on the screw shaft. I have. The tip of the screw shaft is located behind the rotor, and a spiral groove that intersects is formed on the outer periphery of the screw shaft. A part of the slider is engaged with the spiral groove. The intermediate gear is fixed to the tip of the screw shaft, and rotates in conjunction with the handle.
The slider is fixed to the rear end of the spool shaft at substantially the same front and rear position as the engaging portion with the screw shaft. When the slider reciprocates along the screw shaft, the spool shaft and the spool also reciprocate similarly. In this way, by reciprocating the spool with the rotation of the handle, the fishing line is uniformly wound around the outer periphery of the spool.

[0004]

In such a spinning reel, it is important to reduce the size and weight of the spinning reel so that it can be easily cast. However, in the conventional configuration, since the screw shaft on which the intermediate gear is mounted is disposed obliquely below the spool shaft, the left and right thicknesses (lateral widths) of the reel body are increased, making it difficult to reduce the size of the reel body. Further, since the tip of the screw shaft is located behind the rotor, the rear end of the screw shaft located behind the rear end of the retracted spool shaft is located considerably behind, and the front and rear directions of the reel body are The length is also long, which makes it difficult to make the reel body compact.

An object of the present invention is to reduce the size of a reel body.

[0006]

A spinning reel according to a first aspect of the present invention is a reel mounted on a fishing rod, and includes a reel body, a rotor, a spool shaft, a spool, a handle shaft, a pinion gear, and a reciprocating gear. And a moving mechanism.
The rotor has a yarn guide, and is rotatably supported at the front of the reel body. The spool shaft is supported by the reel body so as to be able to reciprocate in the front-rear direction. The spool is fixed to the tip of the spool shaft, and the fishing line guided by the line guide is wound around the outer periphery. The handle shaft is a rotatable shaft disposed on the reel body in a direction intersecting with the spool shaft and having a handle and a master gear mounted thereon. The pinion gear is arranged on the outer peripheral side of the spool shaft so as to mesh with the master gear, and is connected to the rotor. The reciprocating mechanism is a mechanism for reciprocating the spool shaft. The reciprocating mechanism includes a screw shaft disposed above the spool shaft along the spool shaft, one end of which extends inside the rotor and has a spiral groove formed on the outer periphery thereof, and a pinion which is non-rotatably mounted on one end of the screw shaft. An intermediate gear that meshes with the gear; and a sliding member that has an engaging member that engages the spiral groove, is axially fixed to the spool shaft, and reciprocates with the spool shaft by rotation of the screw shaft. doing.

In this spinning reel, when the handle is rotated, the handle shaft is rotated, whereby the master gear is rotated. Then, the pinion gear meshing with the master gear rotates, and the rotor rotates. When the pinion gear rotates, the intermediate gear meshing with the pinion gear also rotates. When the intermediate gear rotates, the screw shaft disposed above the spool shaft rotates, and the sliding member engaging with the screw shaft reciprocates back and forth, and the spool and the spool shaft also reciprocate. Thus, the fishing line guided by the line guide portion of the rotor is uniformly wound around the spool in the front-rear direction.

In this case, since the screw shaft is disposed above the spool shaft, the width of the reel body is reduced, and the reel body can be made compact. Also, since one end of the screw shaft fixing the intermediate gear is arranged inside the rotor,
Since the rear end of the screw shaft is located forward, the front-rear length of the reel body is shortened, and the reel body can be made more compact.

The spinning reel according to the second aspect of the present invention is the spinning reel according to the first aspect.
In the reel described in (1), the fixing portion between the sliding member and the spool shaft is disposed behind the engaging portion between the engaging member and the spiral groove. In this case, since the fixing portion is disposed behind the engaging portion, even if one end of the screw shaft is disposed in the rotor, the spool shaft fixing portion of the slider that has advanced can be configured so as not to interfere with the pinion gear. .

A spinning reel according to a third aspect of the present invention is a spinning reel according to the first aspect.
In the reel described in Item 2, the handle is provided at the tip of the handle shaft, the master gear is provided at the base end of the handle shaft, and the handle shaft is rotatably supported by the reel body at an intermediate portion. In this case, since there is no need to provide a handle shaft through the reel body, the screw shaft can be easily arranged close to above the spool shaft. For this reason, the vertical length (height) of the reel body can be reduced, and the reel body can be made more compact.

[0011] The spinning reel according to the fourth aspect is the spinning reel according to the third aspect.
In the reel described in the above, the reel body rotatably supports the spool shaft and the rotor, a housing portion having an opening on at least one side, a rod mounting portion extending upward from the housing portion,
A cover that covers the opening, and the handle shaft is rotatably supported by the cover. In this case, since the handle shaft is supported only by the lid and is not supported across the two members, the mounting accuracy of the handle shaft is improved.

In addition, a stopper (not shown) that regulates the movement of the engaging member toward the distal end side is provided at the distal end of the hole 27. [Structure of Rotor] As shown in FIG. 1, the rotor 3 has a cylindrical portion 30, and a first rotor arm 31 and a second rotor arm 32 provided on the sides of the cylindrical portion 30 so as to face each other. ing. The cylindrical portion 30 and the rotor arms 31, 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. The front portion 14a of the pinion gear 14 and the spool shaft 20 pass through the through hole of the boss 33a. Front wall 33

Is rotated in conjunction with the rotor 3.

A first bail support member 40 is swingably mounted on the inner peripheral side of the distal end of the first rotor arm 31.
The first bail support member 40 is firstly supported by two bearings 40a.
It is rotatably supported by the rotor arm 31. A line roller 41 is mounted at the tip of the first bail support member 40 to guide the fishing line to the spool 4. A second bail support member 42 is swingably mounted on the inner peripheral side of the tip of the second rotor arm 32. The second bail support member 42 is made of, for example, a material having a higher specific gravity than other portions, and functions as a balancer for eliminating imbalance during rotation caused by the first bale support member 40 and the line roller 41. It is also possible.
A bale 43 is provided between the line roller 41 at the tip of the first bail support member 40 and the second bale support member 42. A bail arm 45 is configured by the bail support members 40 and 42, the line roller 41, and the bail 43. As described above, by mounting the bail support members 40 and 42 on the inner peripheral side of the rotor arms 31 and 32,
The radius of rotation of the bail arm 45 is reduced, making it difficult to reach the hand holding the fishing rod. Therefore, the spool 4 and the fishing rod can be brought closer by shortening the rod mounting portion 12, and the overall size can be reduced.

Here, both bail support members 40, 42
It is swingable about one swing axis M. The point at which the swing axis M intersects with the first bail support member mounting surface of the first rotor arm 31 is defined as the swing center C1, and the swing axis M and the second
When the point at which the rotor arm 32 intersects with the second bail support member mounting surface is the swing center C2, the swing center C2 is located forward of the swing center C1. That is, the swing axis M
Is inclined backward with respect to an axis orthogonal to the spool shaft 20. The bail support members 40 and 42 are arranged such that their swing surfaces are orthogonal to the swing axis M.

Inside the cylindrical portion 30 of the rotor 3, the rotor 3
Is provided. Reverse rotation prevention mechanism 5
0 is a roller type one-way clutch (not shown);
An operating mechanism 51 for switching the one-way clutch between an operating state and a non-operating state. In the one-way clutch, an outer ring is fixed to the housing 10, and an inner ring is fixed to the pinion gear 14. The operation mechanism 51 has an operation lever 52 disposed at a lower portion of the housing unit 10. By swinging the operation lever 52, the one-way clutch is switched between two states. 3 cannot be reversed, and the rotor 3 can be reversed when not operating.

[Structure of Spool] The spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3 and is fixed to the tip of the spool shaft 20. The spool 4 includes a bobbin trunk 4a around which the fishing line is wound, a rear flange 4b integrally formed at the rear of the bobbin trunk 4a, and a front flange 4c fixed to the front of the bobbin trunk 4a. have. The bobbin trunk 4a extends to the outer peripheral side of the cylindrical portion 30 of the rotor 3, and has a trunk length longer than that of a normal spinning reel. The flange height of both flange portions 4b and 4c is lower than that of a normal spinning reel. As a result, the resistance at the time of releasing the line is reduced, so that even when a thin fishing line is wound around the bobbin trunk 4a, the fishing line is hardly twisted.

[Operation and Operation of Reel] In this spinning reel, during casting, the bail 43 is tilted from the yarn winding side to the yarn releasing side. Thus, the first and second bail support members 40 and 42 rotate in the same direction about the swing axis M. At this time, the first and second bail support members 4
The first and second bale support members 40 and 40 are disposed on the inner peripheral side of the first and second rotor arms 31 and 32 and the swing shaft M is inclined rearward with respect to the spool shaft 20. The line roller 41 at the tip moves further inward than the position in the yarn winding posture. For this reason, the fishing line fed during casting is less likely to become entangled with the first bail support member 40 and the line roller 41.

At the time of winding the fishing line, the bail 43 is lowered to the line winding posture. This is automatically performed by the action of a cam and a spring (not shown) when the handle 1 is rotated in the line winding direction. When the handle 1 is rotated in the line winding direction, this rotational force is transmitted to the pinion gear 14 via the handle shaft 12 and the master gear 13. The torque transmitted to the pinion gear 14 is transmitted to the rotor 3 via the front portion of the pinion gear 14, and the rotor 3 rotates in the line winding direction.

On the other hand, the screw shaft 21 is rotated by the intermediate gear 23 which meshes with the pinion gear 14, and the slider 22 which meshes with the spiral groove 21a of the screw shaft 21 has the guide shafts 24a, 24a.
4b to move in the front-back direction. Therefore, the spool shaft 20 and the spool 4 reciprocate in the front-rear direction,
The fishing line guided to the spool 4 by the bail 43 and the line roller 41 is wound substantially uniformly in the front-rear direction on the outer peripheral surface of the bobbin trunk 4 a of the spool 4.

In the spinning reel having such a configuration,
Since the slider 22 reciprocates while being guided by the two guide shafts 24a and 24b, it reciprocates smoothly without rotating or tilting. For this reason, 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 engagement member 26 can be reduced. Therefore, the rear portion of the reel body 2 can be reduced in lateral projection, and the reel body 2 can be made compact.

Further, since the screw shaft 21 is disposed above the spool shaft 20, the lateral width of the reel body 2 is reduced, and the lateral portion of the rear portion of the reel body 2 can be further reduced. Since one end of the screw shaft 21 to which the gear 23 is fixed is disposed inside the rotor 3, the rear end of the screw shaft 21 is located forward, and the front-rear length of the reel body 2 is reduced. Can be made more compact.

Further, since the fixed portion of the slider body 25 with the spool shaft 20 is located behind the engagement portion with the screw shaft 21, even if one end of the screw shaft 21 is arranged in the rotor 3, the slider body advances. The configuration can be such that the spool shaft fixing portion of the slider 22 does not interfere with the pinion gear 14. Further, since the handle shaft 7 is supported only by the lid member 11a, there is no need to provide the handle shaft 7 through the reel body 2. For this reason, the screw shaft 21 can be easily arranged close to the upper side of the spool shaft 20, the vertical length (height) of the reel body 2 can be reduced, and the reel body 2 can be made more compact. . Also, the accuracy of mounting the handle shaft is improved, and the rotation of the handle becomes smooth.

[Other Embodiments] (a) The form of the spinning reel is not limited to the above-described embodiment, but includes a drag mechanism at a front portion or a rear portion, and a brake lever instead of a reverse rotation prevention mechanism. The present invention can be applied to a vehicle equipped with a braking mechanism. (B) The shape of the slider or the like of the level wind mechanism is not limited to the present embodiment.

[0032]

In the spinning reel according to the present invention, since the screw shaft is disposed above the spool shaft, the width of the reel body is reduced, and the reel body can be made compact. In addition, since one end of the screw shaft to which the intermediate gear is fixed is arranged inside the rotor, the rear end of the screw shaft is located forward, and the front and rear length of the reel body is shorter, making the reel body more compact.
