Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bail arm and, more particularly, to a bail arm which is openably and closably mounted between a pair of rotor arms of a spinning reel.

[0002]

2. Description of the Related Art A bail arm for guiding fishing line to a spool is provided on a pair of rotor arms of a spinning reel. The bail arm rotates with the rotor and opens and closes between a line releasing position and a line winding position. The bail arm includes a pair of bail support members, each of which is swingably mounted at a tip of a pair of rotor arms, a fishing line guide provided at a tip of one bail support, a fishing line guide, and the other. Both ends are connected to the tip of the bale support member,
And a veil made of a curved wire. The fishing line guide has a line roller, a fixed shaft fixed to the tip of one bail support member to support the line roller, and a fixed shaft cover fixed to the tip of the fixed shaft.

[0003] One end of the bail is bent and inserted and fixed to the side top of the fixed shaft cover. The other end of the bail is inserted and fixed to the tip of the other bail support member. Grooves are formed on both ends of the bale by machining.The bale deforms the mounting hole by pressing the groove formation part of both ends inserted from the outside, and is caulked to the fixed shaft cover and the bale support member Have been.

In a spinning reel having such a bail arm, when the fishing line is wound on a spool, the bail arm is swung toward the line winding posture and the handle is turned.
Then, the fishing line is guided by the bail, guided to and contacted with the outer peripheral surface of the line roller via the fixed shaft cover. Then, the direction of the fishing line is changed by being guided by the line roller, and the fishing line is wound around the spool.

[0005]

In the above-mentioned conventional bail arm, when the material of the bail is a metal wire, the bale may be deformed when subjected to an external force during transportation or fishing. When the bale is deformed, the rotational balance of the rotor may be lost even if the position of the center of gravity is slightly changed even if the deformation is returned by hand. In addition, a force for tilting the swing shaft acts on the bail support member due to the deformation of the bail, and the bail arm may not be able to open and close smoothly.

Therefore, it is conceivable to use a shape memory alloy wire rod for the bale. Even when a shape memory alloy is used, when an external force is applied to the veil, the veil is temporarily deformed while the external force is applied. However, it is possible to return to the original shape when the external force is removed. For this reason, the veil is less likely to be deformed even when an external force acts. Moreover, since the shape memory alloy has a superelastic property, it is not broken by an external force that normally acts during transportation or fishing.

However, when a shape memory alloy is used, the shape memory alloy, particularly a Ti—Ni alloy, is relatively hard and has excellent wear resistance, so that it is hard and difficult to machine. For this reason, it is difficult to form a groove by cutting, and it is difficult to caulk and fix the bale by forming a groove by cutting as in the conventional case. Therefore, it is conceivable to fix the bail to the fixed shaft cover or the bail support member by bonding. However, when the veil is fixed by bonding, the bale is easily detached due to insufficient strength.

An object of the present invention is to enable a veil made of a shape memory alloy wire to be easily fixed with sufficient strength.

[0009]

The bail arm of the spinning reel according to the first aspect of the present invention is an arm that is openably and closably mounted between a pair of rotor arms of the spinning reel,
The vehicle includes a pair of bail support members, a fishing line guide, and a bail. The pair of bail support members are swingably attached to the tips of the pair of rotor arms, respectively. The fishing line guide is provided at the tip of one bail support member. The bail is made of a curved shape memory alloy wire, and has a deformable portion fixed to the fishing line guide portion and the other end of the bail support member at both ends. Further, the fishing line guide and the other bail support member have locking portions for locking the deformed portion.

In this bail arm, the bail is fixed to the fishing line guide and the bail support member by locking the deformed portion to the locking portion, so that the bail made of a shape memory alloy wire can be easily and sufficiently strong. Can be fixed. A bale arm for a spinning reel according to a second aspect of the present invention is the bale arm according to the first aspect, wherein the shape memory alloy is a superelastic alloy having a thermoelastic martensitic transformation and a temperature at which the martensitic transformation occurs at room temperature or lower. . In this case, since the temperature at which martensitic transformation of the shape memory alloy constituting the veil is at or below room temperature (for example, 15 to 25 degrees Celsius), the room temperature often becomes higher than the temperature at which martensite is generated. It becomes superelastic and returns to its original shape as soon as the external force is removed. When the temperature at which the martensitic transformation occurs in the shape memory alloy is higher than room temperature, when an external force is applied to deform the shape memory alloy, the shape cannot be restored unless heat is applied and the temperature exceeds the temperature. For this reason, handling after deformation is complicated and impractical.

A bail arm of a spinning reel according to a third aspect of the present invention is the spinning reel bale arm according to the second aspect, wherein the superelastic alloy is Ti-Ni-based, Cu-Zn-Al-based, Au-Cd
System, Cu-Al-Ni, Cu-Au-Zn system, Cu-S
The alloy is any one selected from the group consisting of n-based, Cu-Zn-X (X = any one of Si, Sn, Al, and Ga), In-Tl-based, and Ni-Al-based alloys.

A bail arm of a spinning reel according to a fourth aspect of the present invention is the bail arm according to any one of the first to third aspects, wherein the deformed portion is processed and deformed before the shape memory processing. In this case, since the deformed portion is deformed before the shape memory processing, the deformed portion can be easily deformed. A bail arm of a spinning reel according to a fifth aspect is the arm according to the fourth aspect, wherein the deformed portion is obtained by press working.
In this case, the deformation of the deformed portion can be performed in a short time.

A bail arm for a spinning reel according to a sixth aspect of the present invention is the bail arm according to any one of the first to third aspects, wherein the deformed portion is deformed by being processed during the shape memory processing. In this case, by performing the deformation processing of the deformed portion when performing the shape storage process, the state of the deformed portion can be stored, and the deformed portion is not easily deformed. A bail arm for a spinning reel according to a seventh aspect of the present invention is the arm according to the sixth aspect, wherein the deforming portion cools the bale material to a temperature lower than the martensitic transformation temperature before fixing, and in that state, the fishing line guide portion and the other are cooled. It can be obtained by mounting it on the tip of the bale support member and heating it to a temperature higher than the martensite generation temperature to return it to the stored shape. In this case, the bale is cooled to remove the deformation of the deformed part, and after being mounted in that state, the deformed part is heated and deformed to its original state and locked by the locking part and fixed. Even if it is deformed, it can be easily installed by removing it.

The rear end of the spool shaft 20 is fixed to the slider 22 so that it cannot move in the axial direction and cannot rotate. The slider 22 has a screw shaft 2
1, guide shafts 24a arranged in parallel above and below
It is guided in the axial direction by 24b. The intermediate gear 23 is fixed to the tip of the screw shaft 21 and meshes with the pinion gear 14.

[Structure of Rotor] As shown in FIGS. 1 and 4, the rotor 3 has a cylindrical portion 30 and a first rotor arm 31 and a second rotor arm 31 provided on the sides of the cylindrical portion 30 so as to face each other.
And a rotor arm 32. The cylindrical portion 30 and the rotor arms 31, 32 are integrally formed. Cylindrical part 3

On the front wall 33 of the rotor 3, there is provided a cylindrical thread biting prevention member 36 having an opening at the front. The line biting prevention member 36 has a stepped portion 36a at an outer peripheral end portion, and the fishing line wound around the spool 4
And is prevented from entering through the gap between the spool shaft 20 and the shaft shaft 20. [Structure of bail arm] As shown in FIGS.
A bail arm 40 is attached to the tip of each of the second rotor arms 31 and 32 so as to be freely opened and closed. Bale arm 40
The first and second bail support members 41a and 41b are mounted on the inner peripheral sides of the distal ends of the first and second rotor arms 31 and 32, respectively, so as to be swingable, a fishing line guide mechanism 42, and a fishing line guide mechanism 42. And a bail 46 having both ends fixed to the second bail support member 41b. The first bail support member 41a is rotatably supported by the first rotor arm 31 by two bearings 40a. The fishing line guide mechanism 42 is for guiding the fishing line to the spool 4, and is mounted on the tip of the first bail support member 41a. Here, the second bail support member 41b is made of, for example, a material having a higher specific gravity than other portions, and a balancer for eliminating imbalance during rotation caused by the first bail support member 41a and the fishing line guide mechanism 42. Function. Thereby, the rotor 3 including the bail arm 40
Overall, the dynamic balance is balanced.

By mounting the bail support members 41a and 41b on the inner peripheral side of the rotor arms 31 and 32, the radius of rotation of the bail arm 40 is reduced, making it difficult for the user to hold the fishing rod. Therefore, the rod mounting part 1
2, the spool 4 and the fishing rod can be brought closer to each other, and the overall size can be reduced. Here, both bail support members 41a and 41b are swingable about one swing axis M. Then, the swing shaft M and the first rotor arm 3
A point at which the first bail support member mounting surface intersects is defined as a swing center C1, and a point at which the swing axis M intersects with the second bail support member mounting surface of the second rotor arm 32 is defined as a swing center C2. In this case, the swing center C2 is located ahead of the swing center C1. That is, the swing shaft M is inclined rearward with respect to an axis orthogonal to the spool shaft 20. The bail support members 41a and 41b are arranged such that their swing surfaces are orthogonal to the swing axis M.

[Structure of Fishing Line Guide Mechanism] As shown in FIGS. 2, 3 and 5, the fishing line guide mechanism 42 includes a fixed shaft 43, one end of which is fixed to a first bail support member 41a, and a fixed shaft 43. It has a fixed shaft cover 44 integrally formed and a substantially cylindrical line roller 45. The fixed shaft 43 is
As shown in FIG. 5, it is a member manufactured integrally with the fixed shaft cover 44 by cutting. The fixed shaft 43 has a base end extending from the fixed shaft cover 44, and a front end fixed to a fishing line guiding member 47 formed at a front end of the first bail support member 41 a by a fixing screw 56. The fishing line guide member 47 is formed integrally with the tip end of the first bail support member 41a so as to protrude in a cylindrical disk shape. Further, the fixed shaft 45 is positioned in the rotation direction such that the vertex of the fixed shaft cover 44 faces a predetermined direction, and is fitted into the fishing line guiding member 47.

The fixed shaft cover 44 has a substantially conical shape whose apex is deviated from the center, and the apex 44 a faces rearward of the reel with respect to the axis of the fixed shaft 43 and radially outward of the spool 4. ing. A bale 46 is smoothly joined to the ridge 44b at the ridge 44b near the vertex 44a of the cone. The joint between the bail 46 and the fixed shaft cover 44 is deviated from the vertex 44a of the cone toward the fishing line guide side. A recess 44d is formed in the ridge 44c of the fixed shaft cover 44 on the side opposite to the yarn guide.
Further, the decreasing rate of the distance R (FIG. 2) between the vicinity of the joint between the bail 46 and the fixed shaft cover 44 and the line roller 45 to the fishing line contact portion of the spool 4 is greater than the decreasing rate up to that point.

The line roller 45 has a fixed shaft 43 and a bearing 4.
8 so as to be rotatable. The bearing 48 holds the fixed shaft 4 between the fishing line guiding member 47 and the fixed shaft cover 44.
3 is fitted. One end of the inner ring 48a of the bearing 48 is
The other end comes into contact with the fishing line guiding member 47 and the fixed shaft cover 4
4 is in contact with a spacer 49 disposed between the first and second spacers 4. Thus, the inner ring 48a is positioned in the axial direction.

The line roller 45 is fitted in the outer ring 48b of the rolling bearing 48 so as not to be movable in the direction of the fixed shaft cover, and has a circumferential groove 45a which is a guide portion for guiding the fishing line to the spool 4 is formed on the outer peripheral surface. . Line roller 45
Has a locking portion 45b on the inner peripheral surface that protrudes inward so as to lock on the end surface of the outer race 48b of the bearing 48 on the fishing line guiding member 47 side. As a result, the line roller 45 cannot be moved in the direction of the fixed shaft cover 44, and a slight gap is always formed between the line roller 45 and the fixed shaft cover 44.

A thrust receiving ring 50 made of a synthetic resin such as polyacetal resin is arranged between the fishing line guiding member 47 and the end surface of the line roller 45 on the fishing line guiding member 47 side. The thrust receiving ring 50 prevents the line roller 45 from directly contacting the fishing line guiding member 47. [Veil Configuration] As shown in FIGS. 5 and 6, both ends of the bail 46 are inserted and fixed in insertion holes 44g and 41c formed in the fixed shaft cover 44 and the second bail support member 41b. The bail 46 is arranged to be curved outward in the circumferential direction of the spool 4, and guides the fishing line to the line roller 45 via the fixed shaft cover 44. Here, the fixed shaft cover 44 and the fishing line guide side contact portion 46b (FIG. 1) of the line roller side portion 46a (FIG. 2) of the bail 46 and the spool 4
The fixed shaft cover 44 and the bail 46 are configured so that the distance R to the fishing line contact portion becomes shorter from the bail 46 toward the line roller 45.

The veil 46 is made of a curved shape memory alloy wire. Insertion hole 44 of bale 46
At both ends inserted into g and 41c, semicircular concave portions 46a and 46b deformed before the shape memory processing are formed.
The recesses 46a and 46b are formed by, for example, press working. Depressed portions 44e and 41d for caulking and fixing the bail 46 are formed in the defective portion 44d of the fixed shaft cover 44 and the second bail support member 41b facing the concave portions 46a and 46b, respectively. The depressions 44e, 41d are formed after the bail 46 is inserted into the insertion holes 44g, 41c of the fixed shaft cover 44 and the second bail support member 41b, respectively.
The concave portions 46a, 46b are locked by the locking convex portions 44f, 41e formed by 41d, and the bail 46 is fixed to the fixed shaft cover 44 and the second bail support member 41b.
As described above, the concave portions (an example of the deformed portion) are provided at both ends of the bale 46.
46a, 46b are formed, and the locking projections 44f, 41 are formed.
Since the bale 46 is fixed by being locked by e, the bail 46 made of a shape memory alloy wire can be easily fixed with sufficient strength.

Here, as the shape memory alloy, a superelastic alloy having a thermoelastic martensitic transformation and having a temperature at which the martensitic transformation occurs at room temperature (15 to 25 degrees Celsius) or less is preferable. Such a superelastic alloy is Ti-N
i-based, Cu-Zn-Al-based, Au-Cd-based, Cu-Al
-Ni, Cu-Au-Zn, Cu-Sn, Cu-Z
Preferably, the alloy is any one selected from the group consisting of nx (X = any one of Si, Sn, Al, and Ga), an In-Tl-based alloy, and a Ni-Al-based alloy. In particular, a Ti—Ni-based alloy can reduce the weight, so that the dynamic balance caused by the bail 46 can be kept low.

When an external force is applied to the veil 46 made of such a superelastic alloy, the veil 46 is temporarily deformed while the external force is applied. However, when the external force on the bail 46 is removed, the bail 46 returns to its original shape. For this reason, the veil is less likely to be deformed even when an external force acts. Further, since it has a superelastic property, it is not broken by an external force that normally acts during transportation or fishing. In addition, since the rotor 3 is dynamically balanced, even if the bail 46 is deformed, the change in the position of the center of gravity is reduced, and the bail arm 40
And the change in the overall dynamic balance is reduced.

[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 has a tapered cylindrical bobbin trunk portion 4a around which a fishing line is wound around the outer periphery thereof, and a rear flange portion 4b integrally formed at a rear portion of the bobbin trunk portion 4a with a larger diameter.
And a large-diameter front flange 4c fixed to the front of the bobbin trunk 4a. These parts are made of a lightweight metal such as an aluminum alloy and have a small thickness of about 1.2 to 1.5 mm. A disk-shaped front wall 51 is integrally formed at the tip of the bobbin trunk 4a, and a boss 52 fixed to the spool shaft 20 by a pin 53 is formed at the center thereof.

The bobbin trunk portion 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.

A ring-shaped groove 54 is formed in the inner peripheral portion of the rear flange 4b. A damping ring 55 is fitted into the groove 54. The vibration damping ring 55 is a ring made of synthetic resin having elasticity such as polyacetal resin, and has a shape in which a part of an arc is cut out. The outer diameter of the vibration damping ring 55 is larger than the inner diameter D2 (FIG. 4) of the groove 54. For this reason, when fitting the vibration damping ring 55 into the groove 54, both ends of the notch of the vibration damping ring 55 are gripped with a slight force and the diameter is reduced to be smaller than the inner diameter D3 of the edge of the groove 54. And fit it. As a result, the vibration damping ring 55 is attached to the groove 54 using the elasticity of the synthetic resin.

When such a vibration damping ring 55 made of synthetic resin is mounted on the thin spool 4, even if the fishing line hits the spool 4 when the fishing line is wound, the vibration caused by contact is suppressed by the vibration damping ring 55. Is less likely to vibrate. Therefore, even when the fishing line comes into contact with the spool 4 when the fishing line is wound on the metal spool 4, noise such as a bell sound is less likely to be generated. Further, since the damping ring 55 is mounted on the inner peripheral surface of the spool 4, the damping ring 5
5 does not hinder the winding of the yarn, and the size of the entire spool can be suppressed.

[Operation and Operation of Reel] In this spinning reel, during casting, the bail 46 is tilted from the yarn winding side to the yarn releasing side. Accordingly, the first and second bail support members 41a and 41b rotate in the same direction about the swing axis M. At this time, the first and second bail support members 41a and 41b are connected to the first and second rotor arms 31,
32, and the swing shaft M is connected to the spool shaft 2
Since the first bail support member 41a and the line roller 45 at the tip of the first bail support member 41a are tilted backward with respect to 0, the first bail support member 41a moves further inward than the position in the yarn winding posture. For this reason, the fishing line unwound during casting is less likely to be entangled with the first bail support member 41a and the line roller 45.

At the time of winding the fishing line, the bail 46 is lowered to the line winding position. 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.

When the bale 46 falls to the line winding position and the rotor 3 rotates, the fishing line in contact with the rear portion (the contact portion on the fishing line guide side) of the bail 46 is guided to the fixed shaft cover 44 by the bail 46. The fishing line guided by the fixed shaft cover 44 is guided by a line roller 45, the direction of the fishing line is changed by the line roller 45, and the fishing line is wound around the outer periphery of the spool 4.

The distance R between the fishing line guide side contact portion of the fixed roller cover 44 and the line roller side portion 46a of the bail 46 and the fishing line contact portion on the spool 4 becomes shorter as going from the bail 46 to the line roller 45. Since the bail 46 and the fixed shaft cover 44 are configured, the distance from the spool 4 does not increase or decrease, and the fishing line is less likely to be caught. Therefore, the fishing line can be smoothly guided from the bail 46 to the line roller 45.

The fixed shaft cover 44 has a conical shape, and one end of the bail 46 is smoothly joined to the ridge 44b near the vertex 44a of the cone, so that the convex apex 44a on which the fishing line is easily caught is formed. Can be concealed by the veil 46 to avoid it. Therefore, the fishing line is guided to the line roller 45 more smoothly. Other Embodiments (a) As shown in FIGS. 7 to 10, hook-shaped deformed portions 46 c and 46 d may be formed at both ends of the bale 46 before the shape memory processing. The insertion hole 44g formed in the fixed shaft cover 44 penetrates to the fixed shaft 43 side, the insertion hole 41c formed in the second bail support member 41b also penetrates, and the left side in FIG. 10 is wider. In addition, this insertion hole 41
A locking projection 41e formed by the recess 41d is formed in c.

In such a configuration, when the bail 46 is fixed, both ends of the bale are first cooled to a temperature lower than the temperature at which the martensite transformation occurs, and the deformation of the deformed portions 46c and 47d is removed to make them straight. In this state, each insertion hole 44
g, 41d, both ends are inserted, and after insertion, both ends are heated to return to the stored state. Thereby, the deformed portions 46c and 46d appear. The deformed portion 46c on the fixed shaft cover 44 side is locked by being wound around the fixed shaft 43, and the deformed portion 46d on the second bail support member 41b side is locked by the engaging convex portion 41e. Thereby, both ends of the bail 46 are fixed to the fixed shaft cover 44 and the second bail support member 41b.

With such a configuration, the same effect as in the above-described embodiment can be obtained, and the veil 46 made of a shape memory alloy wire can be easily fixed with sufficient strength. (B) As shown in FIG. 11, a coil spring-shaped deformed portion 46e may be formed at the time of the shape memory processing.

[0042]

According to the present invention, the bail is fixed to the fishing line guide portion and the bail support member by locking the deformed portion to the locking portion, so that the veil made of the shape memory alloy wire has sufficient strength. Can be fixed easily.
