Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a drag transmission mechanism for a dual bearing reel.
More specifically, it relates to an improvement in the structure relating to the transmission performance of the drag transmission mechanism of the dual bearing reel.

<Prior Art> Conventionally, as a drag transmission mechanism of a dual-bearing reel, for example, those described in Japanese Patent Publication No. 49-16319, Japanese Patent Publication No. 50-9718, and Japanese Utility Model Publication No. 58-130464 are known. There is.

These conventional dual-bearing reel drag transmission mechanisms are pierced into the spool by operating an operating part of a drag mechanism such as a lever provided on one side frame to rotate the side frame to the other side. Of the spool shaft is slid in the axial direction, and the slide of the spool shaft is transmitted via the spool to the clutch portion of the drag mechanism housed in the other side frame to change the friction degree. It will be done in this way. Some spools themselves form part of the clutch portion of the drag mechanism.

<Problems to be Solved by the Invention> In the above-mentioned conventional drag transmission mechanism for a dual-bearing reel, particularly when a long-distance fishing line is wound on a large-sized dual-bearing reel, when water or seawater adheres to the fishing line. Since the spool on which the fishing line is wound is subjected to internal pressure and expands and deforms in the axial direction, there is a problem in the transmission performance that the spool cannot accurately transmit the slide of the spool shaft.

The present invention has been made to solve such a problem, and an object thereof is to provide a drag transmission mechanism for a dual-bearing reel having good transmission performance in which transmission is not affected by expansion deformation of the spool. It is in.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the drag transmission mechanism of the dual-bearing reel according to the present invention is configured to operate the spool of the spool by operating the operation portion of the drag mechanism provided on one side frame. A spool shaft that penetrates inside and is arranged from one side frame to the other side frame is slid in the axial direction so that the friction degree of the clutch portion of the drag mechanism housed in the other side frame can be varied. In the dual-bearing reel drag transmission mechanism, the clutch part of the drag mechanism is composed of a drag disc engaged with the spool and a pair of clutch plates that are spline-engaged with the spool shaft and sandwich the drag disc from both sides. Is equipped with a spring that urges them in the direction of separating them, and the clutch plate on the spool side is in the axial direction of the spool shaft. A means characterized in that the pressing force of the slide is applied is adopted.

<Operation> According to the above-mentioned means, the slide of the spool shaft is transmitted to the clutch plate constituting the clutch portion of the drag mechanism, and the spool is disengaged from the transmission system of the drag transmission mechanism. An object of the present invention is to provide a drag transmission mechanism for a dual-bearing reel that is not affected and has good transmission performance.

<Embodiment> An embodiment of a drag transmission mechanism for a dual bearing reel according to the present invention will be described below with reference to the drawings.

In this embodiment, the one provided with the lever drag mechanism is shown.

In this embodiment, a right side frame A is provided with an operating portion 1 of a drag mechanism including a turning lever, and a left side frame B is provided with a clutch portion 2 of the drag mechanism.

The operation unit 1 has a linkage mechanism 3 including a cam mechanism or the like incorporated in the right side frame A connected to a spool shaft 4. By rotating the operation unit 1, the spool shaft 4 is slid in the axial direction. Is able to. The spool shaft 4 penetrates through the spool 5 around which the fishing line is wound and is arranged from the right side frame A to the left side frame B, and the spline groove 4'on the left side frame B side. Is engraved.

Further, a handle 6 is provided on the right side frame A outside the operating portion 1, and the handle 6 is provided with a linkage mechanism 7 including a gear meshing combination incorporated in the right side frame A. The spool shaft 4 can be rotated by being connected to the spool shaft 4.

The clutch portion 2 has a donut-shaped drag disc 21 engaged with a pin 40 planted on the end surface portion on the left side frame B side of the spool 5, and engagement grooves 22a, 23a on the inner peripheral surface. The spline is engaged between the spline groove 4'of the spool shaft 4 and is movable in the axial direction of the spool shaft 4 so that the drag disc 21 is clamped from both sides. It is composed of a spring 24 which is fitted in the shaft 4 and is interposed to urge both clutch plates 22 and 23 in a direction to separate them. A small diameter portion 22b is formed on the side of the clutch plate 22 on the spool 5 side opposite to the other clutch plate 23, and a bearing 8 is fitted into the small diameter portion 22b to support the spool 5. It should be noted that this bearing 8 is locked on one side to a stop ring 9 fixed to the spool 5, and on the other side to a disc spring 10 which is locked and fitted to the end of the spline groove 4'of the spool shaft 4. Stop, spool shaft 4,
The spool 5 and the clutch plate 22 are integrally assembled. One clutch plate is provided on the clutch plate 23 on the side opposite to the spool 5 side.
A small diameter portion 23b is formed on the side opposite to 22, and the bearing 20 is fitted into the small diameter portion 23b and supported by the left side frame B. The bearing 20 has a groove 30 provided on the left side frame B.
, And the clutch plate 23 is fixed to the left side frame B.

According to such an embodiment, when the operation portion 1 is rotated toward the tightening side, the spool shaft 4 slides in the left side frame B direction, and the spool 5 is passed through the disc spring 10 and the bearing 8.
Since the clutch plate 22 and the spool 5 on one side are pressed to the other clutch plate 23 side to strongly clamp the drag disk 21, the drag force becomes large. When the operating portion 1 is rotated to the loose side, the spool shaft 4 slides toward the right side frame A, the clutch plate 22 and the spool 5 are followed by the spring 24, and the other clutch plate 23 Since the clutch plates 22 are separated from each other and the drag disk 21 is less clamped, the drag force is reduced.

In such an operation, since the spool 5 is not incorporated in the drag transmission system, the drag transmission does not become inaccurate even if the spool 5 expands and deforms. Further, since the left side frame B side of the spool 5 is prevented from abutting on the clutch plate 22 by the expansion deformation due to the interposition of the bearing 8, the expansion deformation of the spool 5 is mainly performed in the right side frame A direction. As a result, the buffering to the clutch unit 2 is prevented and the drag transmission becomes more accurate. Further, since the contact of the spool shaft 4 with the bearing 8 is via the disc spring 10 and the opposite side of the bearing 8 is in contact with both the clutch plate 22 and the spool 5 (stop ring 9), the thrust load applied to the bearing 8 is increased. Is reduced and one-sided hanging is also prevented, so that the bearing 8 is prevented from being damaged.

<Advantage of Device> As described above, in the drag transmission mechanism of the dual bearing reel according to the present invention, the slide of the spool shaft is transmitted to the clutch plate constituting the clutch portion of the drag mechanism, and the spool is moved from the transmission system of the drag transmission mechanism. Since it is removed, the transmission is not affected by the expansion deformation of the spool, so that the transmission performance is improved.
