Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a double-bearing reel, more specifically, a spool is rotatably supported via a spool shaft between a pair of side frames, and the power generated by the rotational operation of a handle is transferred via a drag mechanism. The present invention relates to a double bearing reel which transmits power to the spool and rotates the spool.

Conventionally, as this type of reel, a spool shaft is rotatably and axially displaceably supported between a pair of side frames, the spool is rotatably supported on the spool shaft, and the spool shaft is rotatably supported by the spool shaft. A drag disk facing the flange of the spool is supported so as to be relatively movable in the axial direction, and a drag washer is interposed between the disk and the flange. A brake plate facing the drag washer is held on at least one of the drag discs, and one of the drag disc or the spool is moved in the axial direction by displacement of the spool shaft in the axial direction, and the brake plate is pressed against the drag washers. The power generated by the rotating operation of the handle is transmitted from the spool shaft to the spool via a drag mechanism, and the drag force caused by the contact plate being pressed against the drag washer is adjusted, thereby adjusting the free rotation resistance of the spool. Reel is suggested.

However, the contact surfaces between the drag washer and the contact plate in this reel are straight flat surfaces perpendicular to the axis of the spool shaft, and both contact surfaces are in full contact with each other. When the drag force is increased by increasing the amount of displacement of the spool shaft in the axial direction, this drag force causes the flanges of the drag disk and spool to bend in the direction of separation, or One side of the side frame was distorted relative to the other, and the outer circumferential portion of the contact surface between the drag washer and the contact plate separated and did not make full contact, and only the central portion of the contact surface was in contact.
If there is partial contact when the drag force is strong, the wear on the center side will be more severe than the wear on the outer peripheral side, and the friction area will become smaller accordingly.
Further, there is a problem that the maximum drag force with respect to the pressure contact force also decreases. Furthermore, since the amount of displacement of the spool shaft in the axial direction is small and the contact surfaces are in full contact even when the drag force is weak, there is a problem that the adjustment range of the drag force is narrow.

The present invention was developed in view of the above-mentioned problems, and an object of the present invention is to move the flanges of the drag disk and spool in the direction of separation when the pressure contact force of the contact plate increases due to movement of one of the drag disk and spool. Even if the contact plate and the drag washer are bent, the radially inner sides of the opposing surfaces of the contact plate and the drag washers are not strongly pressed against each other, and the radially outer sides are strongly pressed over the entire circumferential length to prevent a gap from forming on the radially outside. To provide a double-bearing reel capable of obtaining a predetermined drag force, reducing uneven wear on the facing surfaces of a contact plate and a drag washer, and widening the adjustment range of the drag force.

Accordingly, the present invention rotatably supports a spool between a pair of side frames via a spool shaft, and also provides a drag that faces the spool and the flange side surface of the spool in a plane on the spool shaft. a drag washer is interposed between the disk and the flange, the drag washer having a side surface facing the disk and the flange in plan view; A double bearing reel having a ring-shaped contact plate having a flat contact plane planarly facing a side surface of the drag washer on at least one surface facing the disk, the contact plate being in contact with the drag washer. The drag washer and the contact plate are characterized in that the spacing between the facing surfaces is narrower on the radially outer side of the facing surface of the drag washer and the contact plate than on the radially inner side over the entire length in the circumferential direction.

Embodiments of the reel of the present invention will be described below based on the drawings.

A drag lever 30 is rotatably supported, and by rotating the drag lever 30, the spool shaft 5 is displaced toward the first side frame 1, and the movement of the spool shaft 5 is controlled by the bearing 4, the pinion gear 10, and the spool shaft 5. The force is transmitted to the spool 6 via the bearing 7, and the spool 6 is displaced toward the first side frame 1 together with the spool shaft 5, and the drag washer 9 is pressed against the drag disk 8, and the drag force caused by this pressure contact causes the spool 6 to move. A predetermined resistance is applied to the free rotation of the motor.

The present invention provides a reel configured as described above,
The contact plates 11 and 12 are connected to the drag washer 9.
The radially outer side of the opposing surfaces of the drag washer 9 and the contact plates 11 and 12 when in contact with the opposing surfaces of the drag washer 9 and the contact plates 11 and 12 is narrowed in the distance between the opposing surfaces over the entire circumferential length relative to the radially inner side, and the drag Contact plate 1 due to displacement of one of disk 8 and spool 6
1 and 12, even if the drag disk 8 and the first flange 62 are bent in the direction of separation, the contact plates 11 and 12 and the drag washer 9 are strongly pressed against each other on their opposing surfaces in the radial direction inside. The radially outer side is strongly pressed over the entire length in the circumferential direction to eliminate the formation of a gap on the radially outer side.

In the above configuration, the means for narrowing the spacing between the opposing surfaces is, for example, as shown in FIG. This is done by slanting the contact plates 11 and 12 on the opposing surfaces 8a and 62a outward in the radial direction with respect to the contact surface of the drag washer 9.

The contact plates 11 and 12 are connected to the opposing surfaces 8a and 6.
2a, and may be tilted in the radial direction with respect to the drag washer 9.
As shown in the figure, it may be held so as to be displaceable relative to the opposing surfaces 8a, 62a, and may be tilted in the radial direction relative to the drag washer 9 by this displacement.

Furthermore, although the contact plates 11 and 12 are held by set screws, they may be held by other holding means.

Further, the drag washer 9 is held movably in the axial direction within a holding cylinder 13 extending axially outward from the outer peripheral edge of the first flange 62.
Alternatively, it may be held on the drag disk 8, and the holding means is not particularly limited.

Further, the contact plates 11 and 12 are made of stainless steel, and the drag washer 9
is made of asbestos.

The drag disk 8 is movable relative to the first side frame 1, and a spring 15 is interposed between the drag disk 8 and a bearing 7 that supports the spool 6 via a spacer 14. This spring 15 urges the disk 8 and spool 6 in a direction away from the drag washer 9, and also urges the support cylinder 1 of the first side frame 1.
An adjusting body 16 is screwed onto the adjusting body 16, and the rotation operation part of the adjusting body 16 is exposed to the outside of the side frame 1, and the drag disk 8 is moved in the axial direction by an external rotation operation. The spacing between the facing surfaces of the Tsug disk 8 and the first flange 62 is adjusted.

The drag lever 30 also includes a boss portion 31 having a plurality of protrusions 31a that protrudes in the axial direction of the spool shaft 5, and a knob portion that protrudes outward from the boss portion 31 along the second side frame 2. 32
a recessed part of a rotary body 40 in which the boss part 31 is rotatably supported on the outer peripheral surface of the support cylinder 2a, and the protrusion 31a provided on the boss part 31 is screwed into the support cylinder 2a. 40a, and the rotating body 40 is screwed forward or backward by rotating the drag lever 30. Further, the knob portion 32 of the lever 30 is provided with a gear 7 that meshes with an arc-shaped rack 70 provided on the second side frame 2.
A positioning mechanism is provided which rotatably supports the adjuster 72 having the adjustment tool 1 and includes a ball 81 and a spring 82 which urges the ball toward the second side frame 2 side.

The spool shaft 5 is a straight shaft having no stepped portion on its outer peripheral surface, and transmission pins 51, 52, and 53 projecting radially outward are provided in the middle thereof. By doing so, for example, the bearings 4 and 7 supported on the spool shaft 5 can be of the same size, which is economical.

In the figure, 17 includes a ratchet 17a provided on the drag disk 8, a sound pawl 17b pivotally supported on the first side frame 1, and a spring (not shown) that biases the pawl toward the ratchet. The sound mechanism 18 is an annular cover that prevents rainwater from entering the space between the drag disk 8 and the first flange 62, and is supported on the holding cylinder 13. Further, 33 is a retaining screw for the lever 30.

The present invention is constructed as described above, and when winding a fishing line onto the spool 6 from a state where the spool 6 is in a free rotation system as shown in FIG. 1, the drag lever 30 is moved counterclockwise in FIG. The rotating body 40 is caused to spirally advance, and its thrust displaces the spool shaft 5 toward the first side frame 1, and the spool 6 supported on the spool shaft 5 resists the force of the spring 15. This movement of the spool 6 moves the drag washer 9 in the direction of the drag disk 8, and the drag washer 9 is attached to the contact plate 11 held on the drag disk, and the spool 6 is moved in the direction of the drag disk 8. The contact plate 12 held on the first flange 62 of the drag washer 9 is pressed against the drag washer 9, while the handle 23 is rotated to transfer the power to the handle shaft 21, pinion gear 10, spool shaft 5, drag disc 8, and the drag washer 9. The force is transmitted to the first flange 62 via the plate 11, the drag washer 9, and the contact plate 12, and the spool 6 is forcibly rotated.

However, if the pressing force due to the movement of the spool 6 is small, the contact plate 1
Due to the inclination of the opposing surfaces 8a and 62a that hold the contact plates 11 and 12, the contact plates 11 and 12 are in contact with the drag washer 9 in a movable state using their outer peripheral edges as fulcrums. This allows for a wider adjustment range and smoother drag action.

Moreover, when the pressure contact force due to the movement of the spool 6 is increased, the drag disk 8 is increased as shown in FIG.
and when the first flange 62 is bent in the direction of separation,
On the radially inner facing surfaces of the drag washer 9 and the contact plates 11 and 12, the distance between the opposing surfaces is wider than on the radially outer side, and this radially inner facing surface is not strongly pressed. The opposing surfaces on the radially outer side, where the distance between the opposing surfaces is narrower than the inner side in the radial direction, can be strongly pressed over the entire circumferential length of the opposing surfaces without separating them. Since the radially outer sides of the facing surfaces of the drag washer 9 and the contact plates 11 and 12 can be strongly pressed over the entire length in the circumferential direction without being affected, the drag force against the pressure contact force can be strengthened and a predetermined drag force can be obtained. This is possible. Furthermore, uneven wear of the contact plates 11, 12 and the drag washer 9 can be reduced.

If the spool 6 is to be in a free rotating system, the drag lever 30 is rotated clockwise in FIG.
At the same time, the spool shaft 5 is moved toward the second side frame 2.

In the embodiment described above, the opposing surfaces 8a, 62a of the drag disk 8 and the first flange 62
By tilting the contact plates 11 and 12 with respect to the drag washers 9, the contact plates 1
The radially outer side of the opposing surface between the drag washer 9 and the contact plates 11, 12 when the drag washers 1, 12 are in contact with the opposing surface of the drag washer 9,
Although the distance between the opposing surfaces is narrowed toward the inner side in the radial direction, other contact plates 11 and 12 are provided as shown in FIG.
The surface of the drag washer 9 that faces the drag washer 9 itself is inclined, or the drag washer 9's face that faces the contact plates 11 and 12 itself is sloped as shown in FIG. Instead, an annular lumen is provided in the central portion of the opposing surfaces 8a, 62a of the drag disk 8 and the first flange 62 that hold the contact plates 11, 12, and the contact plate 11 is provided in these lumens. , 12 may be accommodated. Further, the contact plate may be provided on both the drag disk 8 and the first flange 62, or may be provided on only one of them. In this case, it is preferable to hold the drag washer 9 on a member that does not hold the contact plate.

Further, in addition to moving the spool 6 in the axial direction to press the drag washer 9 against the drag disk 8, the drag disk 8 is also moved to bring the drag washer 9 into contact with the first flange 62 of the spool 6.
It may be pressed against. In this case, movement of the spool 6 in the axial direction is prevented.

Further, although the drag lever 30 is supported by the second side frame 2, it may be supported by the first side frame 1.

Further, although the drag lever 30 is used as a means for displacing the spool shaft 5 in the axial direction, the displacing means is not particularly limited.

As described above, the present invention rotatably supports a spool between a pair of side frames via a spool shaft, and a drag is attached to the spool shaft and faces the spool and the flange side surface of the spool in a planar manner. a drag washer is interposed between the disk and the flange, the drag washer having a side surface facing the disk and the flange in plan view; A double bearing reel having a ring-shaped contact plate having a flat contact plane planarly facing a side surface of the drag washer on at least one surface facing the disk, the contact plate being in contact with the drag washer. Since the distance between the opposing surfaces is narrowed on the radially outer side of the opposing surface between the drag washer and the contact plate when the drag washer contacts the opposing surface with respect to the radially inner side over the entire circumferential length,
Although the entire contact plane of the contact plate with a flat contact plane can be brought into pressure contact with the planar side surface of the drag washer, if the drag force due to this pressure becomes large, the flanges of the drag disk and spool will inevitably separate. Even when the drag washer and the contact plate are bent in this direction, the radially inner facing surfaces of the drag washer and the contact plate have a wider spacing over the entire circumferential length than the radially outside, and this radially inner facing surface Since the pressure contact will not be strong, the radially outer opposing surface, where the spacing between the opposing surfaces is narrower than the radially inner surface over the entire circumferential length, can be pressed against the planar side surface and flange side surface of the drag washer without separating it. It can be strongly pressed over the entire circumferential length, that is, the radially outer side of the opposing surface between the drag washer side surface and the contact plane of the contact plate can be strongly pressed over the entire circumferential length without being affected by the inevitable deflection of the drag disk and flange. Since the drag force can be strongly pressed, the drag force relative to the pressure contact force can be increased, a predetermined drag force can be obtained, and the range of adjustment of the drag force by pressure contact can be widened. Moreover, since the radially outer sides of the facing surfaces of the drag washer and the contact plate can be pressed together over the entire length in the circumferential direction, uneven wear of the drag washer and the contact plate can be reduced.
