Description

[Detailed Description of the Invention] The present invention relates to a drag mechanism for a fishing reel, and more specifically, to a drag mechanism for a fishing reel, which is equipped on a fishing reel to wind a fishing line onto a spool by rotating a handle, and which provides resistance to the rotation of the spool. Regarding the mechanism.

Generally, this type of drag mechanism is used to arbitrarily adjust the winding force of the fishing line wound onto the spool according to the size of the fish caught and the pull of the fish, so that the fish can be caught smoothly. For example, when you are in the middle of catching a fish and suddenly encounter a strong pull from the fish, it is all you can do to hold the fishing rod, and it is difficult to adjust the tightening of the drag mechanism immediately and accurately. There was a problem that the wire would break without being pulled out from the spool depending on the load.

The present invention was devised in view of the above circumstances, and its purpose is to be able to adjust the rotational resistance of the spool, but also to ensure that a load greater than the fishing line's resistance is applied to the spool regardless of the above adjustment. For example, it is an object of the present invention to provide a drag mechanism that allows the spool to rotate freely and reliably prevents the fishing line from breaking.

More specifically, a cylindrical body is provided to protrude in a direction in which an interlocking shaft projects from the reel body in conjunction with the rotation of the spool, a clutch case that rotates together with the interlocking shaft is housed inside the main body, and the clutch case is attached to the case. A plurality of friction plates are incorporated, and an elastic body is interposed between the friction plates and an adjustment body screwed onto the main body, and the clutch case is adapted to the resistance strength of the fishing line wound on the spool with respect to the main body. The clutch case is fixed with a load slightly lower than the maximum load applied to the fishing line, and is further provided with a sliding mechanism that allows the clutch case to rotate freely relative to the main body when a load greater than the fixed load is applied to the fishing line. It is something.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The drag mechanism of a fishing reel according to the present invention will be described below with reference to the embodiments shown in the drawings.

The fishing reel shown in the figure is a so-called spinning reel, and in the figure, 1 is a reel body that has a mounting leg 1a for attaching to a fishing rod, and 11 is a reel body that is rotatably supported on this reel body 1 via a bearing 11a. The barrel shaft 12 is an interlocking shaft supported by the reel body 1 via the barrel shaft 11 so as to be rotatable and movable in the front and rear directions.

Further, a handle shaft 1 is provided on the side wall of the reel body 1.
3 is rotatably supported, and a master gear 14 that meshes with a pinion gear 11b formed on the cylindrical shaft 11 is provided at the protruding portion of the handle shaft 13 into the reel body 1.

Further, the cylindrical shaft 11 has one end projected forward from the front wall of the reel body 1, and the rotating frame 2 is fixed to this projecting end, and the rotation of the handle shaft 13 causes the master gear 14 and the pinion gear 11 to be connected to each other.
The rotary frame 2 is configured to rotate via the cylinder shaft 11 and the cylinder shaft 11.

On the other hand, the interlocking shaft 12 has a front end that projects forward from the front wall of the reel body 1, and the spool 3 is fixed to this projecting end.

The present invention relates to a drag mechanism that provides resistance to the rotation of the spool 3, in which one end of the interlocking shaft 12, which rotates together with the spool 3, protrudes from the reel body 1, and the drag mechanism provides resistance to the rotation of the spool 3. A cylindrical main body 4 extending in the same direction as the protruding direction of the shaft 12 is provided, and a clutch case 5 that rotates together with the interlocking shaft 12 is housed inside the main body 4.
A set of friction plates 6a... and 6b... is incorporated, and an elastic body 7 made of, for example, a coil spring is interposed between one of these friction plates and an adjustment body 40 screwed onto the protruding end portion of the main body 4, When the clutch case 5 is fixed to the cylindrical body 4 with a load slightly lower than the maximum load suitable for the proof strength of the fishing line wound on the spool 3, and a load greater than this fixed load is applied to the fishing line, the above-mentioned A sliding mechanism 8 is provided to allow the clutch case 5 to freely rotate relative to the cylindrical body 4.

That is, in the embodiment shown in the figure, the reel body 1
A cylindrical shaft 12a is inserted into the center of the cylindrical body 4 formed on the rear wall, and this cylindrical shaft 12a is rotatably supported on the rear wall of the reel body 1, while the rear of the interlocking shaft 12 The clutch case 5, which has an end formed into a square shaft and is fitted into the cylindrical shaft 12a so as to be movable only in the axial direction, and has a bottomed cylindrical shape, is attached to the outer periphery of the cylindrical shaft 12a.
The clutch case 5 is rotatably and axially movably supported relative to the cylindrical shaft 12a, and the clutch case 5 is rotated together with the cylindrical shaft 12a via the two sets of friction plates 6a... and 6b.

In addition, of the two sets of friction plates 6a and 6b assembled in the clutch case 5, one of the friction plates 6a
... is mounted on the clutch case 5 so as to be movable only in the axial direction by a spline connection, and is mounted on the cylindrical shaft 12a so as to be rotatable relative to the
The other friction plate 6 is attached to the clutch case 5.
The interlocking shaft 12 is rotatable relative to the interlocking shaft 12a and is mounted internally so as to be movable only in the axial direction relative to the cylindrical shaft 12a. By screwing the adjustment body 40 into place, the two friction plates 6a... and 6b... are pressed together via the elastic body 7, thereby providing the desired resistance to the rotation of the interlocking shaft 12, and ultimately the spool 3.

On the other hand, the sliding mechanism 8 has a large number of sliding type engagement teeth 8a and 8b each having a mountain-shaped cross section formed on opposing sides of the bottom wall of the clutch case 5 and the rear wall of the reel body 1. The sliding mechanism 8 is formed by both engaging teeth 8a and 8b.

This sliding mechanism 8 has both the engaging teeth 8a and 8b.
The clutch case 5 is fixed to the reel body 1 by the engagement of the friction plates 6 and 6.
The spool 3 is rendered unrotatable by pulling the interlocking shaft 12 through the clutch case 5 and the cylindrical shaft 12a, and the load for fixing the clutch case 5 is applied to the spool 3 as described above. The load is set to be slightly lower than the maximum load that is compatible with the yield strength of the fishing line, and the load at which the clutch case 5 rotates freely relative to the reel body 1 is a load that is higher than the fixed load of the case 5 on the fishing line, that is, the fishing line breaks. The load is set at a certain level.

In addition, 41 in the figure indicates the adjustment body 40 and the elastic body 7.
An E-ring 42 interposed between the cylindrical body 4 and the cylindrical body 4 is an O-ring for locking the adjusting body 40 attached to the outer periphery of the cylindrical body 4.

The drag mechanism of the present invention has the above-mentioned configuration, and in order to catch a fish with a fishing reel equipped with this drag mechanism, the master gear is rotated by rotating a handle (not shown) attached to the handle shaft 13. 14. Rotate the rotating frame 2 via the pinion gear 11b and the cylindrical shaft 11, and rotate the spool 3.
The fishing line is wound in sequence.

Then, in the middle of winding up the fishing line, the adjusting body 40 is arbitrarily rotated in accordance with the size of the fish caught and the strength of the pull, and the friction plates 6a and 6b are pressed together via the elastic body 7. By adjusting the frictional resistance, a desired resistance can be applied to the rotation of the spool 3.

On the other hand, for example, if you suddenly encounter a strong pull from a fish and it becomes all you can do to hold the fishing rod, you may no longer be able to accurately adjust the rotational resistance of the spool 3 using the adjustment body 40, or you may tighten the adjustment body 40 too much. Even if the friction plates 6a... and 6b... no longer slip on each other, if the fishing line is subjected to a maximum load D that is compatible with the proof strength of the line, in other words, a load to the extent that the fishing line breaks, the slipping will occur. Specifically, the mechanism 8 works by sliding the engaging teeth 8a on the clutch case 5 side against the elastic body 7 so as to overcome the engaging teeth 8b on the reel body 1 side.
By pulling the clutch case 5, the spool 3 is rotated freely relative to the reel body 1,
As a result, the fishing line is pulled out from the spool 3 and there is no risk of the line breaking.

In the above embodiment, the sliding mechanism 8 is provided between the clutch case 5 and the reel body 1, but it may also be provided between the adjusting body 40 and the E-ring 41. In this case, the sliding mechanism 8 is provided between the clutch case 5 and the reel body 1. E-ring 41
and one end of the elastic body 7, and one of the friction plates 6a.
and the other end of the elastic body 7 must be fixed.

In addition, the sliding mechanism 8 may be provided between the elastic body 7 and the friction plate 6a.

Further, in the above embodiment, the drag mechanism according to the present invention is installed on the spinning reel, but it may be installed on the double-bearing reel.

As described above, according to the drag mechanism of the present invention, even if the adjusting body cannot accurately adjust the frictional resistance of the friction plate and the spool becomes unable to rotate, the fishing line wound around the spool will still be able to withstand the fishing line's resistance. When a maximum load compatible with the fishing line is applied, in other words, a load to the extent that the fishing line breaks, the clutch case and, by extension, the spool become free to rotate via the sliding mechanism, so the fishing line is pulled out from the spool. This eliminates the risk of line breakage, and due to the synergistic effect of the friction plate and the sliding mechanism as a whole, the fishing line can be wound extremely quickly and without line breakage when catching a fish. be.
