Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing prevention device for a spinning reel for fishing, and more particularly, to a reversing prevention device capable of reversing a rotor that rotates integrally with a pinion barrel using a wedge action of a rolling member. The present invention relates to a spinning reel reverse rotation prevention device that can be switched.

[0002]

2. Description of the Related Art Conventionally, a rotor is prevented from reversing (ON) and reversible (OFF) using the wedge action of a rolling member of this type.
A device disclosed in Japanese Patent Application Laid-Open No. 54-141285 has already been known as a spinning reel reverse rotation preventive device which can be switched between (1) and (2). In the reverse rotation prevention device having the above structure, there is a fear that the wedge effect does not work unless the rolling member is moved to an accurate position in order to turn on the ON state, so that the rolling member is accurately moved to the position where the wedge effect works. It must be manufactured, but it requires considerable high precision to adjust the angle of movement of the retainer, so that there is a problem that the productivity is reduced and the cost is increased.

[0003] In order to solve the above problems, those disclosed in JP-A-6-58348 and JP-A-6-225573 have been developed. The reverse rotation prevention device having the above-described structure is configured such that an elastic body formed by bending a leaf spring is disposed on each of the rolling members, and the retainer is rotated in a direction of turning on the retainer. Move in the direction in which the wedge action works. That is, even if there is a certain manufacturing error, the error is absorbed by the movement of the rolling member, and the wedge function works normally.

However, even with the above-described structure, attaching or forming an elastic body for biasing a small rolling member to each rolling member is an extremely detailed operation, and is ultimately fundamental. The current situation is that it has not been resolved.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art,
The goal is to improve accuracy without increasing
Another object of the present invention is to provide a spinning reel reverse rotation preventing device which can improve productivity with a simple configuration, reduce costs, and perform an accurate wedge action.

[0006]

In order to achieve the above object, the present invention has a technical means that a pinion which is rotated by rotation of a handle is provided outside a main shaft provided on a reel body so as to be able to move back and forth. A shaft cylinder is rotatably fitted, an inner ring is fitted so as to rotate integrally with the coaxial cylinder outside the pinion shaft cylinder, and an outer ring positioned outside the inner ring is fixed to the reel body so as to be non-rotatable, Between these two wheels, there is rotatably interposed a retainer holding a plurality of rolling members capable of taking a position where the two wheels are engaged with each other by wedge action and a position where the two wheels are idle and do not wedge. The spinning reel reverse rotation preventing device is provided with an operating rod connected to an operating mechanism that moves and holds the rolling member between a position where the rolling member acts as a wedge and a position where the rolling member does not act by rotating the retainer. Wherein the retainer is urged at least to a position where the rolling member performs a wedge action by a biasing means in a direction of wedge action from a predetermined turning position which is turned at the time of switching by the operating mechanism. is.

The urging means may be any means capable of holding the ON state of the retainer by pulling the operating rod of the retainer. Specifically, the urging means is extended between the retainer and a member attached to the reel body. This can be achieved by a tension coil spring or the like.

[0008] According to the above structure, when the rotor rotating forward when the operating mechanism is turned on attempts to rotate reversely,
The reverse rotation is prevented by the wedge action, but if there is a manufacturing error or the rolling members and the inner and outer rings are worn out, the operation of the operating mechanism alone will not cause the rolling members to bite into both wheels. Even when the function does not work, the retainer is urged by the urging means in a direction in which wedge action is further performed than the intended rotation position rotated by the operation mechanism. , The rolling member bites into both wheels, and the wedge action works accurately.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a part of a spinning reel provided with a reverse rotation preventing device A according to the present invention, and a pinion barrel that is rotated by rotation of a handle outside a main shaft 2 provided on a reel body 1 so as to be slidable in the front-rear direction. 3 and a reverse rotation preventing mechanism A for switching the rotation direction of the coaxial cylinder 3 is provided outside the pinion shaft cylinder 3.
A rotor 4 for winding a fishing line around a spool 2 'attached to the tip of the main shaft 2 is detachably mounted so as to rotate integrally.

The above-described reverse rotation prevention mechanism A includes a main shaft 2
An inner ring A1 is fitted so as to rotate integrally with the pinion shaft cylinder 3 located outside the outer ring A, and an outer ring A2 is non-rotatably fixed to the reel body 1 so as to be located outside the inner ring A1. A retainer A4 that rotatably holds a plurality of rolling members A3 that can take a position between the two wheels to bite into the two wheels and act as a wedge and a position between the two wheels to play idle and not to act as a wedge. It is configured.

[0011] The rolling member A3 is formed in a cylindrical shape,
It is movably fitted into an arc-shaped guide groove A21 provided inside the outer ring A2, and moves between the guide groove A21 and the inner ring A1 between a position where the retainer A4 acts as a wedge and a position where it does not act. It is designed to be switchably held. The guide groove A21 has a shallow groove A211 at the end in the direction in which the rolling member A3 acts as a wedge, and an end in the direction in which the rolling member A3 does not act as a deep groove A212 gradually increasing from the shallow groove.
As a result, the rolling member A3 is moved to the shallow groove A211.
When the rolling member A3 moves to the deep groove A212, the wedge action is not performed when the rolling member A3 moves to the deep groove A212.

The retainer A4 is formed in a cylindrical shape.
A concave portion A41 that fits with an operation ring A5, which will be described later with reference to FIG. A guide hole A42 for holding the rolling member A3 on the peripheral side surface of the retainer A4 and moving the wedge member in a direction in which the wedge function works and a direction in which the wedge function does not work to maintain the state is provided. Inside the guide hole A42, as shown in FIG. 3, the depth of the guide groove A21 from the deep groove A212 to the shallow groove A21 is increased.
A rolling member holding piece A43 protruding in one direction is provided, and the tip of the holding piece A43 and the guide hole A42 are provided.
A part of the rolling member A3 is located between
A gap A44 is provided to the extent that the gap A44 is exposed from the inner peripheral surface of No. 4.

When the retainer A4 is rotated in the direction of arrow X shown in FIG. 3 in which the wedge action does not work, the rolling member holding piece A43 causes the rolling member A3 to ride on the guide groove A4.
21 and fitted in the deep groove A212.
In this state, since the rolling member A3 rides on the rolling member holding piece A43, the rolling member A3 idles between the outer ring A2 and the inner ring A1, and the pinion barrel 3 and the rotor 4 can rotate forward and reverse. Conversely, when the retainer A4 is rotated in the direction indicated by the arrow X in which the wedge action is exerted, the rolling member A3 moves to the gap A44 and maintains the state of being fitted into the shallow groove A211 of the guide groove A21. In this state, since the rolling member A3 enters the gap A44, the rolling member A3 bites into the outer ring A2 and the inner ring A1 to perform a wedge action.
Reverse rotation of the direction is not possible.

An operation ring A5 for rotating the retainer A4 is fitted to the retainer A4 as clearly shown in FIG. The operation ring A5
Is formed on the inner peripheral surface thereof with a convex portion A51 which fits into the concave portion A41 of the retainer A4, and is integrated with the retainer A4 by fitting the convex portion A51 into the concave portion A41. The operating ring A5 has an operating rod A5 connected to an operating mechanism 5 for moving the retainer A4 between a position where the rolling member A3 acts as a wedge and a position where the rolling member A3 does not act as a wedge.
2 are integrally formed.

The operating mechanism 5 has a connecting member 52 connected to the operating rod A52 at the end of the rotating shaft 51, which is rotatably mounted so as to penetrate the reel body 1 in the front-rear direction and is rotatable. At the other end, a lever 53 for rotating the rotating shaft 51 is provided. The connecting member 52 is formed in a cylindrical shape with a bottom and has a bulged portion 54 formed on the peripheral side surface from the center of the rotating shaft 51 to the outside. The connecting projection 55 is provided in an eccentric state.

The operating rod A52 is formed in a strip shape, and is provided on a peripheral side surface of the operating ring A5 so that the wide surface of the operating rod A52 is directed in the axial direction of the operating ring A5 and protrudes outward. A connection hole A53 in which the connection protrusion 55 of the operation mechanism 5 is fitted is provided on the wide surface thereof.

A tension coil spring 6 as urging means for urging the retainer A4 in the direction of wedge action is stretched between the operating rod A52 and the pin erected on the reel body 1. When the retainer A4 is rotated to the predetermined rotation position B in FIG. 2 where the retainer A4 acts as a wedge by the operation of the operation mechanism 5, the rolling member A3 according to the reverse rotation prevention device A manufactured with high precision.
Bites into the inner race A1 and the outer race A2 to act as a wedge. However, the accuracy of the reverse rotation preventing device A is poor, or the outer peripheral surface of the rolling member A3, the outer peripheral surface of the inner ring A1,
When the rolling member A3 cannot bite into the inner ring A1 and the outer ring A2 due to the wear of the shallow groove A211 and the wedge action cannot be performed, the tension coil spring 6 pulls the operating rod A52 to move the retainer A4 to the predetermined rotation position. B is further biased to the error absorbing position B 'in the direction of wedge action, so that the rolling member A held by the retainer A4
3 is made to reliably bite into the inner ring A1 and the outer ring A2 so as to perform a wedge action.

[0018]

According to the present invention, the following effects can be obtained by the above configuration. If the pinion shaft cylinder that rotates forward when the operating mechanism is turned on attempts to rotate in the reverse direction, the wedge action will work and the reverse rotation will be prevented, but if there is an error in manufacturing,
Even if the rolling member and the working surface of the inner and outer rings are worn out by use, and the rolling member does not bite into both wheels and the wedge action does not work by operating the operating mechanism alone, the urging means is further used from that position By the urging force in the direction in which the wedge action acts, the rolling member rotates together with the retainer in the direction in which the wedge action acts, and bites into both wheels to reliably prevent reverse rotation. Therefore, it is possible to improve the productivity with a simple structure without increasing the accuracy and to reduce the cost,
Moreover, it is possible to provide a spinning reel reverse rotation prevention device that can simplify the assembly operation.
