Description

[Detailed Description of the Invention] The present invention relates to a drag mechanism for a fishing reel, in particular, a rotating side member consisting of a spool rotatably supported on a reel body or a rotating body that rotates together with the spool, and a rotating member fixed to the reel body or the reel body. The present invention relates to a drag mechanism that is interposed between a stationary side member made of a fixed body and provides resistance to the rotation of the spool.

Generally, this type of drag mechanism supports in series around the axis of the rotating member a plurality of friction plates that are movable in the axial direction and a coil spring that biases the friction plates in one direction. An adjustment body for adjusting the amount of deflection of the coil spring is screwed onto the stationary side member;
By rotating the adjustment body, the coil spring is deflected and pressed against the friction plate, thereby applying a braking force to the rotation of the rotating member.

However, in the case of this conventional structure, the braking force is adjusted using only the coil spring, so it is not possible to finely adjust the braking force in the low braking area, or the braking force in the high braking area cannot be adjusted. It was impossible to make adjustments.

The present invention was devised in view of the above points, and the purpose is to be able to finely adjust the braking force in the low braking area while obtaining a large braking force in the high braking area, and to This also allows adjustments to be made.

Therefore, in the configuration of the present invention, a rotating side member consisting of a spool rotatably supported on a reel body or a rotating body rotating together with the spool, and a stationary side member consisting of the reel body or a fixed body fixed to the reel body. A drag mechanism interposed in the spool to apply a braking force to the rotation of the spool,
A plurality of friction plates movable in the axial direction, a coil spring that biases the friction plates in one direction, and a leaf spring are supported in series in the axial direction around the axis of the rotating side member, and the The stationary side member is provided with an adjustment body that adjusts the amount of deflection of each spring and adjusts the braking force in an adjustment range from an adjustment start position to an adjustment end position, and the plate spring is adjusted to have higher elasticity than the coil spring. Only the coil spring is deflected in a low braking region from a starting position to a predetermined position to enable fine adjustment of the braking force, and the leaf spring is deflected in a high braking region from the predetermined position to an adjustment end position. , the braking force increases with respect to the amount of operation of the adjusting body.

An embodiment of the drag mechanism of the present invention will be described below with reference to the drawings.

The one shown is a hollow reel body 20 with legs for attaching to a fishing rod on the top surface and a through hole on the front surface.
A cylindrical drive shaft 22 having a pinion gear 21 is rotatably supported in the through-hole portion of the drive shaft 22 through a bearing, and a rotating shaft having a bail arm (not shown) is attached to the outer circumference of the tip end of the drive shaft 22. While attaching the frame 23, a spool shaft 25 having a spool 24 is freely movable in the front and rear direction in the shaft hole of the drive shaft 22,
At the same time, a handle shaft 26 extending in a direction orthogonal to the axis of the drive shaft 22 is freely rotatably supported on the side wall of the reel body 20 so that the handle shaft 26 enters the inside of the reel body 20. A master gear 27 that meshes with the pinion gear 21 is provided in the part, and a handle (not shown) is provided in the projecting part to the outside of the reel body 20. Rotation of this handle drives the drive shaft 22 and causes the rotation. A fishing reel in which the frame 23 is rotated and the spool 24 is moved back and forth via a reciprocating mechanism 28 to wind a fishing line around the spool 24.
4 or a drag mechanism is interposed between a rotating side member A such as the spool shaft 25 that rotates together with the spool 24 and a stationary side member B consisting of the reel body 20 or a fixed body fixed to the reel body 20. be.

The drag mechanism according to this invention includes a plurality of friction plates 1 that are movable in the axial direction around the axis of the rotating member A, a coil spring 2 that biases the friction plates 1 in one direction, and a plate spring. 3 in series in the axial direction, and on the stationary side member B, the amount of deflection of each of the springs 2 and 3 is adjusted in the adjustment range from the adjustment start position to the adjustment end position to adjust the braking force. body 4 is provided, and the leaf spring 3 is made more elastic than the coil spring 2, so that only the coil spring 2 is deflected in a low braking region from the adjustment start position to a predetermined position, thereby making it possible to finely adjust the braking force. In addition, the leaf spring 3 is bent in the high braking region from the predetermined position to the adjustment end position, so that the increase in braking force with respect to the operating amount of the adjusting body 4 becomes large.

However, in the configuration shown in FIG. 1, the rotary tube 5 is fitted to the end of the spool shaft 25 extending into the reel body 20 so as to be non-rotatable but movable in the axial direction. The outer periphery of the reel body 20 is freely supported for rotation only in a through hole 29 provided on the rear surface of the reel body 20, and a plurality of first and second friction plates 1a, 1b and a leaf spring 3 are arranged around the outer circumference of the rotary cylinder 5. body 4 are arranged in series, and the leaf spring 3 is connected to the first body 4.
These first friction plates 1a are interposed between the friction plates 1a.
and the leaf spring 3 cannot be rotated with respect to the rotary cylinder 5,
and supports movably in the axial direction, and the second
The friction plate 1b is supported non-rotatably and movably in the axial direction with respect to the inner peripheral surface of the support tube 30 extending outward from around the through hole 29, while the adjustment body 4
is screwed onto the support cylinder 30, and the coil spring 2 is interposed between the adjustment body 4 and the second friction plate 1b.

The drag characteristic when only the coil spring 2 is used is, for example, the characteristic shown in line A in FIG. 4, and the drag characteristic when only the leaf spring 3 is used is, for example, as shown in line B in FIG. The drag characteristics when the coil spring 2 and the leaf spring 3 are combined are as shown in the fourth figure.
As shown by line C in the figure, the characteristic is a combination of the A characteristic and the B characteristic.

The leaf spring 3 is, for example, a dish-shaped spring. Further, a lining plate may be interposed between the first and second friction plates 1a and 1b.

The present invention is constructed as described above, and the adjustment body 4
Coil spring 2 and leaf spring 3 by rotating in one direction.
The rotary cylinder 5 that supports the first friction plate 1a by bending the first and second friction plates 1a and 1b, and the spool that fits into the rotary cylinder 5 so as to be movable only in the axial direction. A braking force is applied to the rotation of the shaft 25, and when the braking force is to be reduced, the adjusting body 4 is rotated in the opposite direction to elastically restore the coil spring 2 and the leaf spring 3. Friction plate 1
The rotational resistance of the rotary cylinder 5 is reduced by reducing the pressure contact force between a and 1b.

However, in a low braking region where the amount of rotational operation of the adjustment body 4 is small, only the coil spring 2, which has a lower elasticity than the leaf spring 3, is mainly bent, and the friction plates 1a, 1
The pressure contact force b is gradually increased, and by this gradual increase in the pressure contact force, the braking force can be finely adjusted.

As the amount of rotational operation of the adjusting body 4 increases, the plate spring 3 is bent together with the coil spring 2, and the pressing force of the friction plates 1a, 1b is gradually increased. By increasing the braking force, a large braking force can be obtained in a high braking region, and this large braking force can be adjusted.

In the embodiment described above, the leaf spring 3 is interposed between the friction plates 1, but it may be interposed between the friction plate 1 and the adjustment body 4 as shown in FIG. 5, for example.

Further, the adjustment body 4 is connected to the support tube 3 of the reel body 20.
Although the rotary operation structure is screwed into the reel body 20, it is also possible to use a swing operation structure that is pivoted to the reel body 20, for example.

Further, the drag mechanism of the present invention may be incorporated in the rear part of the reel body 20 as shown in the figure, or alternatively, it may be incorporated between the spool 24 and the spool shaft 25 at the front of the reel body 20. In this case, the spool 24
supports the spool shaft 25 rotatably and supports the spool shaft 25 so as to be movable only in the axial direction relative to the reel body 20, making the spool shaft 25 a stationary member.

As described above, according to the present invention, the braking force can be finely adjusted in the low braking region, and furthermore,
Since the leaf spring is deflected in the high braking region, a large braking force can be obtained in the high braking region, and this large braking force can also be adjusted.
