DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastening member detent structure, and more particularly, to a fastening member which is screwed to a second member for fastening a first member of a fishing reel having at least a flat surface to a rod-shaped second member. The present invention relates to a fastening member detent structure of a fishing reel for detenting a member.

[0002]

2. Description of the Related Art In fishing reels such as spinning reels and dual-bearing reels, for example, a rod or pinion gear or a handle shaft (an example of a second member) is provided with a rotor or a handle (an example of a first member) and a nut (an example of a fastening member). (Example). Since this nut rotates together with the pinion gear and the handle shaft, it is easy to loosen due to inertial force and vibration acting on the rotor and the handle.

In order to prevent the nut from loosening,
A thin metal retainer is attached to the fixing nut. The retainer is a substantially raindrop-shaped member made of sheet metal having a large-diameter portion formed at one end and a small-diameter portion formed at the other end. In the large diameter portion, for example, when the nut is a hexagonal nut having six outer peripheral corners, a star-shaped nut locking hole having twelve inner peripheral corners such that two hexagons are displaced by 30 degrees. Are formed, and the outer peripheral shape of the nut is 30 in the nut locking hole.
It can be locked non-rotatably every degree. The small diameter portion has a screw insertion hole through which a small screw can be inserted.For example, by screwing a small screw into a screw fixing hole formed on the front side of the rotor, the retainer is fixed to the rotor so that it cannot rotate, and the nut is fixed. It is stopped.

[0004]

In the above-described conventional rotation preventing structure, the nut locking portion only locks the nut at, for example, every 30 degrees. The position of the insertion hole and the screw fixing hole does not match. If the positions of the two holes do not match, the small screw cannot be screwed into the screw fixing hole, and the rotation of the nut cannot be stopped. For this reason, when rotating the nut with a tool to fix the rotor, the operator must fasten the nut while paying attention to both the tightening torque and the rotation phase of the nut. However, even if care is taken, if the nut does not turn in a rotation phase of between 30 degrees, it is necessary to further turn or loosen the nut so that the screw insertion hole of the retainer matches the screw fixing hole. If this is done, the tightening torque of the nut will fluctuate. If the tightening torque of the nut is too tight, the inner diameter of the pinion gear becomes small, and the pinion gear and the spool shaft come into contact with each other, so that the rotation of the rotor becomes heavy. On the other hand, if the tightening torque is too low, the rotor will rattle. If the nut tightening torque fluctuates in this manner, there is a possibility that the fixed state of the rotor with respect to the pinion gear and the rotational state of the rotor will be adversely affected.

SUMMARY OF THE INVENTION It is an object of the present invention to suppress fluctuations in the tightening torque of a fastening member for fastening a first member to a second member, thereby making it difficult to loosen the fastening member.

[0006]

According to a first aspect of the present invention, there is provided a fishing reel fastening member detent structure for fastening a first member of a fishing reel having at least a flat surface to a rod-shaped second member. A structure for preventing a screwed fastening member from rotating, comprising a retainer, a fixing member, and a fixing portion. A retainer configured to contact at least a part of an outer peripheral shape of the fastening member to lock the fastening member in a non-rotatable manner; and a plane of the first member spaced from the fastening member locking portion. An insertion portion is formed at an opposed position to be long in a direction intersecting the radial direction of the fastening member. The fixing member is a member that is inserted through the insertion portion and fixes the retainer to the end surface of the first member. The fixing portion is formed on a plane of the first member and can fix a fixing member inserted into the insertion portion.

In this structure, the first member is fastened to the second member by screwing the fastening member to the second member. Then, the outer peripheral shape of the fastening member is locked by the fastening member locking portion of the retainer, and the fixing member is inserted into the insertion portion and fixed to the fixing portion to fix the retainer. Thereby, the fastening member is prevented from rotating. Since the insertion portion is formed long along the direction intersecting the radial direction of the fastening member, the fixing portion can face the insertion portion even if the rotation phase of the fastening member is shifted, and the insertion portion of the retainer can be inserted. The fixed member thus formed can be fixed to the fixing portion. For this reason, a variation in the tightening torque of the fastening member for fastening the first member to the second member can be suppressed, and the fastening member can be hardly loosened.

Degrees or 60 degrees. If the first central angle is set as described above, the fastening member can be prevented from rotating by the arc-shaped long hole having the minimum length regardless of the rotational phase of the fastening member.

According to a fifth aspect of the present invention, there is provided a fishing reel rotation preventing structure according to the fourth aspect, wherein one end of the retainer is non-rotatably disposed on a plane of the first member at an interval smaller than the first central angle. At least an arcuate rotation locking portion that can be stopped is formed, and an uneven portion that is locked to the rotation locking portion is formed at one end of the retainer. In this case, since the retainer is non-rotatably locked to the first member by the rotation locking portion and the concave and convex portion, even if the fixing member is loosened, the retainer does not rotate. Therefore, the fixing member only needs to prevent the retainer from falling off from the fastening member, and the structure of the fixing member is simplified, and the retainer is also prevented from rotating, so that the fastening member can be more reliably prevented from rotating.

[0012] In a sixth aspect of the invention, there is provided a fishing reel fastening structure according to the fifth aspect, wherein the second central angle of the arc of the rotation locking portion is larger than the first central angle of the insertion portion. In this case, since the second central angle is larger than the first central angle, one end of the retainer can be securely locked regardless of the rotation phase of the retainer attached to the fastening member.

According to a seventh aspect of the present invention, there is provided a fishing reel rotation preventing structure according to any one of the fourth to sixth aspects, wherein the first central angle (R1) of the arc-shaped long hole is 360 degrees. (N = 1,2,2)

0 / NA). In this case, the first central angle of the arc-shaped long hole can be determined according to the number of locking positions of the fastening member locking portion of the retainer. Regardless, the retainer can prevent the rotation of the fastening member.

According to an eighth aspect of the invention, there is provided a fishing reel rotation preventing structure according to the seventh aspect, wherein the fastening member is a hexagon nut, and the fastening member locking portion locks an outer peripheral corner of the fastening member. It has a locking hole having an inner peripheral angle formed every possible 30 degrees, and the first central angle of the arc-shaped long hole is 30 degrees. In this case, if the retainer is rotated by 30 degrees, the fastening member can be prevented from rotating in any rotation phase, so that even if the first central angle is 30 degrees, the fastening member can be reliably rotated. I can stop it.

According to a ninth aspect of the present invention, there is provided a fishing reel rotation preventing structure according to any one of the first to eighth aspects, wherein the fixing member is a small screw, and the fixing portion is a female screwed with the small screw.

And a fastening member engaging portion is a hole formed in the large diameter portion according to the outer peripheral shape of the fastening member, and the insertion portion is formed in the small diameter portion. I have. In this case, since the fastening member locking portion is formed by the hole formed in the sheet metal retainer, the fastening member locking portion can be formed by simple processing such as pressing.

According to an eleventh aspect of the invention, there is provided a fishing reel rotation preventing structure according to any one of the first to tenth aspects, wherein the fastening member locking portion is partially cut away.

As shown in FIG. 2, the braking portion main body 31 includes a braking cylinder 40 arranged concentrically with the rotor 3 on the inner peripheral side of the rotor 3, and a rotation supporting the braking cylinder 40 in a tiltable and non-rotatable manner. It has a cylinder 41 and a drum section 42 provided on the reel body 2b.

The brake cylinder 40 is a thin metal cylinder having a bottomed cylindrical shape, and a sliding contact portion 40a at the tip of the peripheral portion is disposed between the drum portion 42 and the pressure contact portion 30d of the brake lever 30.

The rotary cylinder 41 has a large diameter portion 41a and a small diameter portion 4a.
1b, a stepped metal cylindrical member having a large diameter portion 41a and an external tooth portion 41c meshing with the inner peripheral portion of the braking cylinder 40.
Are formed. The one-way clutch 32 and the brake cylinder 40 are non-rotatably locked to the external teeth 41c. A bearing 43 is arranged between the large diameter portion 41a and the pinion gear 12. A bearing 44 is disposed outside the small diameter portion between the small diameter portion and the reel body 2b. Therefore, the rotating cylinder 41 has a front portion rotatably supported by the pinion gear 12 by the bearing 43, and a rear portion rotatably supported by the reel body 2 b by the bearing 44. The rotating cylinder 41 is connected to the rotor 3 by the one-way clutch 32.
Are rotated integrally with each other in the yarn feeding direction, and are connected to the rotor 3 so that the rotating force of the rotor 3 does not act upon winding.

A conical coil spring 45 is disposed between the brake cylinder 40 and the one-way clutch 32 for returning the tilted brake cylinder 40 to its original posture. A flange 46 for positioning the brake cylinder 40 is fitted between the brake cylinder 40 and the bearing 44.

a is attached.

The one-way clutch 32 is of the outer ring idle type, in which the outer ring is non-rotatably connected to the inner peripheral surface of the cylindrical portion 3a of the rotor 3, and the inner ring is non-rotatably connected to the rotary cylinder 41.

The brake holding unit 21 holds the lever 51 at two positions, the lever 51 being swingable between a holding position and a release position, an operation shaft 52 which advances and retreats by swinging the lever 51. And a toggle spring mechanism 53. The operating shaft 52 is urged forward by a pressing spring 54, and moves forward when the lever 51 swings to the holding position due to engagement with the reel body 2b, and retracts when swinging to the release position.

[Rotor Assembling Procedure] When the rotor 3 is incorporated into the pinion gear 12, the braking unit 20 is mounted on the reel body 2 in advance. With the braking portion 20 mounted on the reel body, the cylindrical portion 3 a of the rotor 3 is moved to the pinion gear 12.
To the front part 12a. Then, the rotor 3 is non-rotatably mounted on the pinion gear 12 by the chamfered portion 12c formed on the front portion 12a of the pinion gear 12. Subsequently, the nut 15 is screwed into the male screw portion 12b of the pinion gear 12, and the rotor 3 is fastened to the pinion gear 12.

When the nut 15 is completely tightened with a predetermined torque, the retainer is mounted on the nut 15. At this time, the mounting position is adjusted so that the fixing portion 18 can face the insertion portion 16d of the retainer 16. Since the insertion portion 16d is formed by the arc-shaped long hole 16e having the first central angle of 30 degrees, even if the nut 15 stops at any rotational phase,
By adjusting the mounting position, the fixing portion 18 must be
You can start from d.

When the retainer 16 is located at a position where the fixing portion 18 can be seen from the insertion portion 16d, the screw member 17 is inserted into the insertion portion 16d, and the screw member 17 is tightened by a driver.
When the screw member 17 is rotated while pressing the screw member 17 with a driver, the screw member 17 is screwed into the fixing portion 18 and screwed into the fixing portion 18. As a result, the retainer 16 is fixed, and the nut 15 is prevented from rotating.

Here, the insertion portion 16 is formed into an arc-shaped long hole 16e.
With this configuration, the fixing portion 18 can be viewed from the insertion portion 16d regardless of the rotational phase of the nut 15. Therefore, the screw member 17 can be screwed into the fixing portion 18, and the retainer 16 can be reliably fixed to the front wall 3 d of the rotor 3. For this reason, the nut 15 can be prevented from rotating regardless of the rotational phase of the nut 15, and a variation in the tightening torque of the nut 15 can be suppressed, so that the nut 15 can be hardly loosened.

[Reel Operation and Operation] At the time of casting, the bail arm 9 is tilted to the line releasing position side and the fishing rod is swung out, whereby the fishing line is paid out from the outer periphery of the spool 4. At the time of winding the fishing line, when the handle 1 is rotated in the line winding direction, the bail arm 9 returns to the line winding position by a return mechanism (not shown). The turning force of the handle is transmitted to the pinion gear 12 via the handle shaft 10 and the face gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear. At this time, since the rotor 3 rotates in the line winding direction, this rotational force is not transmitted to the rotating cylinder 41. When the pinion gear 12 rotates, the rotation is transmitted to the oscillating mechanism 7 by an intermediate gear (not shown), and the spool shaft 8 reciprocates in the front-rear direction.

To exchange the fish with the rotor 3 in the reverse direction, the lever 51 is swung to the release position. As a result, the operation shaft 52 moves backward. And brake lever 3
0 is rocked by the coil spring 34 to the braking release position.
In this state, the user interacts with the fish by operating the brake lever 30. When the fishing line is pulled by the fish and the rotor 3 reverses in the line payout direction, the rotational force is transmitted to the rotating cylinder 41 via the one-way clutch 32 as described above,
Further, it is transmitted to the braking cylinder 40. As a result, the braking cylinder 40 rotates integrally with the rotor 3.

Then, the operation lever 30a of the brake lever 30 is gripped with the middle finger by the gripping operation of the fishing rod while the leg 2d is sandwiched between the middle finger and the ring finger of the hand holding the fishing rod. Swinging in the clockwise direction, the pressure contact portion 30d of the brake lever 30
2 is pressed radially outward, the braking cylinder 40 is tilted to the position shown by the two-dot chain line in FIG. 2, and the outer surface of the sliding contact portion 40a is pressed against the brake liner 42b. As a result, a braking force acts on the rotor 3 that rotates in the reverse direction. This braking force can be adjusted by adjusting the force applied to the brake lever 30,
The reverse rotation amount of the rotor 3 can be arbitrarily adjusted. During this adjustment,
Since the operation lever 30a can be finely operated with the middle finger, the braking force can be finely adjusted.

When the rotor rotates at the time of winding or unreeling, the nut 15 is easily loosened due to vibration or rotation. Also, if the tightening torque of the nut 15 fluctuates,
The rotation of the rotor is likely to be heavy or rattle. However, in the present embodiment, the nut 1 has a predetermined torque.
Regardless of the rotational phase of the nut 15 when the nut 5 is tightened, the nut 15 can be reliably prevented from rotating. For this reason, the tightening torque of the nut 15 can be made hard to fluctuate, the rotation of the rotor 3 becomes light, and
Rattle is less likely to occur.

When moving the fishing spot or storing the reels, the lever 51 is swung toward the holding position. As a result, the operation shaft 52 moves forward, and the brake lever 30 swings to the braking position. When the brake lever 30 is at the braking position, the braking cylinder 40 is braked in the same manner as during braking.
As a result, the fishing line is not paid out by the weight of the tackle or the like.

[Other Embodiments] (a) As shown in FIGS. 5 and 6, the front wall 3d of the rotor
Alternatively, an arc-shaped internal tooth 3g may be formed at the end of the small-diameter portion 16b of the retainer 16, and an uneven portion 16f engaged with the internal tooth 3g may be formed at the end of the small-diameter portion 16b. The retainer 16 can be prevented from rotating by the engagement between the internal teeth 3g and the uneven portion 16f. For this reason,
Even if the screw member 17 becomes loose, the retainer 16 does not rotate, and the nut 15 can be more reliably prevented from rotating.

The second central angle (R2) of the arc of the internal teeth 3g is:
It is larger than the first central angle (R1), for example, 36 degrees. This is determined in consideration of the circumferential length of the uneven portion 16f. Pitch angle of internal teeth 3g (interval of internal teeth 3g)
Is substantially smaller than the first central angle (R1), for example, about 2 degrees. By forming the internal teeth 3g having such a small pitch, the retainer 16 can be fixed at a finer pitch. In such a configuration, the screw member 17
Need only prevent the retainer 16 from floating from the nut 15. Therefore, an appropriate retaining means such as a C-shaped retaining ring for the retainer 16 may be used instead of the screw member 17 as the fixing member.

(B) In the above embodiment, the rotation preventing structure is used for the nut 15 for fastening the rotor. However, the rotation preventing structure can be applied to the rotation preventing of other nuts such as the nut for fastening the handle of the dual bearing reel.

7 and 8, a dual-bearing reel employing another embodiment of the present invention comprises a reel body 101,
Handle 10 rotatably mounted on reel body 101
2 and a handle 10 provided inside the reel body 101.
And a spool 103 for winding the bobbin which is rotated by the rotation of 2.

The reel body 101 includes a pair of left and right side plates 11.
0, 111, and a pair of side covers 113, 114 covering both sides of the reel frame.
And The side cover 114 has a handle 102
Are rotatably supported.

At the tip of the handle shaft 115, a handle 1
The crank arm 120 constituting 02 is non-rotatably mounted. A handle handle 121 is rotatably attached to the tip of the crank arm 120. At the tip of the handle shaft 115, a chamfered portion (both not shown) parallel to the male screw portion is formed.

As shown in FIG. 8, a hexagonal cap nut 125 for fixing the crank arm 120 to the handle shaft 115 is screwed into the male screw portion. Cap nut 12
5 is provided with a retainer 126 for preventing the cap nut 125 from rotating. The retainer 126 has the same structure as the above embodiment. The retainer 126 is fixed to the crank arm 120 by a screw member 127 made of a small screw. The screw member 127 is connected to the crank arm 12.
It is screwed into a fixing portion (not shown) consisting of a female screw hole formed at 0. Center angle R1 of the arc of insertion portion 126d
Is, for example, 30 degrees. With such a configuration, effects similar to those of the above-described embodiment can be obtained.

The present invention can be applied to all fishing reels in which the first member having a flat surface is mounted on the second bar-shaped member with a nut.

(C) In the above-described embodiment, the hexagonal nut is prevented from rotating. However, the shape of the nut to which the rotation preventing structure of the present invention is applied is not limited to this. The present invention can be applied to a structure in which nuts of all shapes such as nuts and nuts having parallel chamfers are prevented from rotating.

(D) In the above-described embodiment, a nut is exemplified as the fastening member. However, the fastening member is not limited to the nut, and other screws such as a hexagon bolt may be used.

[0063]

According to the present invention, since the insertion portion is formed along the direction intersecting the radial direction of the fastening member, even if the rotation phase of the fastening member is shifted, the insertion of the retainer attached to the fastening member is achieved. The fixing portion can be viewed from the portion, and the fixing member inserted through the insertion portion of the retainer can be fixed to the fixing portion. For this reason, a variation in the tightening torque of the fastening member for fastening the first member to the second member can be suppressed, and the fastening member can be hardly loosened.
