Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel, and more particularly to a structure for applying a braking force to free rotation of a spool.

[0002]

2. Description of the Related Art Conventionally, as this type of fishing reel, for example, as shown in FIG.
In some cases, an adjustment knob 33 is provided on a bearing portion 32 of a spool shaft 31 that rotates integrally with the spool shaft 31. In FIG. 9, the bearing 3
2 is provided with an adjustment knob 33 axially threaded from the outside of the housing 34, and the end of the adjustment knob 33 is brought into contact with the tip of the spool shaft 31.

The original function of the adjustment knob 33 is to adjust the play of the spool 30 attached to the spool shaft 31 in the left and right direction, but it is possible to apply a braking force to the rotation of the spool by tightening it strongly. That is, when the adjustment knob 33 is screwed rightward, the spool shaft 3
The pressure is applied to the tip of the spool 1, and valves 33 a, 33 a provided inside the adjustment knob 33 close in the direction of the adjustment knob 33, and apply pressure to the side surface of the spool shaft 31. Therefore, a braking force acts on the rotation of the spool 30. Therefore, when the spool 30 is rotated freely to release the fishing line and the device is dropped into the water, a resistance due to the braking force is given to the rotation, and excessive rotation of the spool can be suppressed to prevent backlash of the fishing line. .

[0004]

However, in the above-described structure, when the spool (30) is rotated by rotating a spool (31) by turning a handle (not shown), the brake is applied to the rotation of the handle for winding the fishing line. The force will act. Therefore, if a strong brake is applied when the fishing line is released, the rotation of the handle becomes heavy when the take-up line is wound, so that a strong brake cannot be applied to the spool 30.

Therefore, the applicant has applied a brake force to the spool shaft during free rotation of the spool when releasing the fishing line, but applied a brake to the spool shaft during winding of the fishing line rotated by the handle. A double-bearing type fishing reel having a structure in which no force acts has already been proposed (JP-A-10-174540).

FIGS. 10 and 11 are views for explaining a dual-bearing reel having the above-described structure. In FIG.
The dual bearing reel includes a left housing 41 and a right housing 4
2, spool 43, spool shaft 44, clutch mechanism 45, handle 46, drag mechanism 47, drive mechanism 4
8, a brake mechanism A, a tapered cylinder A1, a coil spring A2, and a brake force adjusting knob A3.

In this structure, the amount of contact with the spool shaft 44 is increased or decreased by compressing and returning the coil spring A2 wound around the tapered surface formed on the spool shaft 44 in contact. At the same time, by reducing the winding diameter of the coil spring A2 due to the rotation of the spool shaft 44 for feeding out the fishing line, a resistance force is applied to the spool shaft 44 to apply a braking force to the rotation of the spool 43. Further, since the winding diameter of the coil spring A2 is increased with respect to the rotation of the spool shaft 44 for winding the fishing line, no resistance force acts on the spool shaft 44.

The technique disclosed in Japanese Patent Application Laid-Open No. H10-174540 has an unprecedented superior effect.
However, when the motor rotates at a high speed, it is difficult to obtain a sufficient braking force. In addition, if the material and shape of the coil spring A2 are appropriate, sufficient braking force can be obtained, but the production of the coil spring A2 requires cost and time, and a fishing reel can be provided at a low price. Will be gone.

An object of the present invention is a novel structure in which a braking force is applied when the spool rotates freely when releasing the fishing line, but no braking force is applied when the spool is driven and rotated by the handle when winding the fishing line. Another object of the present invention is to provide a fishing reel that can easily cope with high-speed rotation of a spool.

[0010]

In view of the above-mentioned object,
The fishing reel of the present invention has a first clutch mechanism for performing a clutch-on operation for transmitting rotation of the power means to a spool attached to a spool shaft and a clutch-off operation for releasing transmission of rotation of the handle to the spool. A first clutch member attached to the spool shaft so as to be rotatable in the rotation direction of the spool shaft, and a first clutch member fixed in the rotation direction of the spool shaft and movable in the axial direction. Attached to the spool shaft as shown
The first clutch member and the second clutch member in accordance with the clutch-off operation of the first clutch mechanism.
A clutch-on operation for engaging the first clutch member and a clutch-off operation for disengaging the first clutch member and the second clutch member according to the clutch-on operation of the first clutch mechanism. And a braking force applying means for applying a braking force to the first clutch member.

As a result, resistance due to the braking force is applied to the free rotation of the spool when the fishing line is released, and excessive rotation of the spool is suppressed, and backlash of the fishing line can be prevented. When the fishing line is wound, the brake is released, and the spool can be lightly driven by the handle without any resistance due to the braking force. Further, since the brake is turned on / off by the clutch operation, a structure that gives a strong braking force when the brake is turned on can be easily provided.

In another aspect of the present invention, in addition to the fishing reel of the above-described invention, the first clutch mechanism includes a drive gear that rotates by rotation of the power means, a drive gear attached to the spool shaft, and a clutch. The power is fixed in the rotation direction of the spool shaft during the ON operation and transmits the rotation of the power means to the spool shaft. A second pinion gear for releasing transmission of rotation of the means to the spool shaft, the second clutch mechanism further includes a first coil spring disposed between the pinion gear and the second clutch member; And a second coil spring disposed between the first clutch member and the second clutch member.

Thus, the second clutch mechanism is turned on in response to the clutch off operation of the first clutch mechanism, and the second clutch mechanism is turned on in response to the clutch on operation of the first clutch mechanism. A clutch-off operation can be performed. Further, since the movement of the pinion gear in the axial direction is used, it is advantageous in terms of space and stable operation is possible.

According to another aspect of the present invention, in addition to the fishing reel of the above-described invention, the braking force applying means includes a brake member that contacts the first clutch member, a brake adjustment knob, and a brake member and a brake adjustment knob. And elastic means for pressing the brake material against the first clutch member.

Thus, the braking force applied to the first clutch member and thus to the second clutch mechanism can be adjusted. Further, a strong braking force can be easily obtained by strengthening the elastic member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fishing reel according to the present invention will be described below with reference to the drawings. The fishing reel is a so-called double-bearing reel, in which the spool is supported at both ends. However, the present invention can be applied to a single-bearing type reel.

FIG. 1 is a sectional view showing a main part of an embodiment of a fishing reel according to the present invention. In FIG. 1, a spool shaft 3 to which a spool 2 is attached is rotatably supported between a bearing 1a provided in a right housing 1 and a bearing (not shown) provided in a left housing (not shown). I have. The rotation of the spool 2 can be switched between drive rotation and free rotation by switching the clutch on and clutch off of the first clutch mechanism 4.

The first clutch mechanism 4 is composed of a drive gear 7 attached to a rotating shaft 6 rotated by rotation of a handle 5 serving as a power means, and a pinion gear 8 attached to the spool shaft 3 and meshing with the drive gear 7. Become.
The pinion gear 8 is fixed in the rotation direction of the spool shaft 3 and transmits the rotation of the handle 5 from the drive gear 6 to the spool shaft 3 during the clutch-on operation. In addition, during the clutch-off operation, the pinion gear 8 is operated by operating the clutch lever 10 (see FIG. 2) in FIG.
Is moved toward the pinion gear 8 to move in the axial direction of the spool shaft 3. Thus, the pinion gear 8 is in a free state in the rotation direction of the spool shaft 3, and the transmission of the rotation of the handle 5 to the spool shaft 3 is released.

An example of the structure of the first clutch mechanism 4 is shown in FIGS. 2 to 4, for example. FIGS. 2 to 4 show the structure of the manual clutch mechanism. When the clutch lever 10 is set to the ON state, the pinion gear 8 is completely engaged with the spool shaft 3 and is directly connected as shown in FIG. Thereby,
When the pinion gear 8 rotates, the spool shaft 3 and the spool 2 simultaneously rotate.

FIG. 5 shows an example of the meshing shape between the spool shaft 3 and the pinion gear 8. The spool shaft 3 has a large-diameter cylindrical portion 3a to which the spool 2 is attached, and a fitting portion 3
b is formed, and then a small-diameter cylindrical portion 3c is formed. The fitting portion 3b has a substantially oval cross section, and can be fitted into a groove 8a described later. The pinion gear 8 has
A groove 8a into which the fitting portion 3b of the spool shaft 3 fits, and a hole 8b through which the small-diameter cylindrical portion 3c passes are formed. When the fitting portion 3b fits into the groove 8a, the spool shaft 3 and the pinion gear 8 are joined and can be integrally rotated. Further, when the fitting portion 3b is separated from the groove 8a by the movement of the pinion gear 8, the spool shaft 3 and the pinion gear 8 become free from each other and rotate separately.

On the other hand, as shown in FIG. 2, when the clutch lever 10 is set from on (solid line state) to off (dotted line state), the eccentric 11 at the center of the clutch lever 10 rotates. At the same time, the position of the boss 12 erected on the eccentric 11 moves downward in FIG. Since the jack member 13 is directly connected to the boss 12, the jack member 13 also moves downward. The jack member 13 has a step 13a.
When step 3 moves downward in FIG. 2, step 13a pushes down yoke 14. Since the yoke 14 engages with and supports the central groove 8d of the pinion gear 8,
In accordance with the movement of the yoke 14, the pinion gear 8 also descends as shown in FIG.

As shown in FIG. 4, when the neck of the pinion gear 8 is retracted, the engagement between the spool shaft 3 and the pinion gear 8 is cut off, the pinion gear 8 idles, and its rotational movement is not transmitted to the spool 2. That is, spool 2
Becomes free.

As described above, the rotation of the spool 2 from the handle 5 causes the drag mechanism 14 including the star drag 14a to rotate.
, The rotation can be switched between a driving rotation performed by a clutch-on operation of the first clutch mechanism 4 and a free rotation in which the rotation of the handle 5 is separated and rotated freely by the clutch-off operation.

The spool shaft 4 is further provided with a second clutch mechanism 15. Second clutch mechanism 1
Reference numeral 5 denotes a first clutch member 16 attached to an end of an attachment portion 3d of the spool shaft 3 further extending from the small-diameter cylindrical portion 3c, a pinion gear 8 and a first clutch member 16
And a coil spring 18 mounted in a free state on the spool shaft 3 between the pinion gear 8 and the second clutch member 17.
The first clutch member 16 and the second clutch member 17
And a coil spring 19 attached to the spool shaft 3 in a free state. The spring force of the coil spring 18 is set to be larger than the spring force of the coil spring 19.

The cross section of the mounting portion 3d of the spool shaft 3 has a substantially oval shape like the fitting portion 3b.

As shown in FIG. 6, the first clutch member 16 has a cylindrical shape that penetrates a center hole 20a1 formed in an inner wall 20a of a cylindrical member 20 having an H-shaped cross section attached to the opening 1b of the right housing 1. It has a portion 16a, a flange portion 16b formed on the cylindrical portion 16a, and two protrusions 16c formed on one end of the cylindrical portion 16a.
The cylindrical portion 16a is provided with a circular through-hole 16d having a diameter that fits loosely with the longitudinal diameter of the cross-sectional track shape of the mounting portion 3d of the spool shaft 3. First clutch member 1
6 is attached so that the projection 16c is located on the left side in FIG. The cylindrical member 20 is fixed to the right housing 1 by swaging 21.

As shown in FIG. 7, the second clutch member 17 is a disk having a predetermined thickness and an outer diameter slightly larger than the outer diameter of the cylindrical portion 16a of the first clutch member 16. On one surface thereof, there is provided a concave portion 17a formed so as to be gradually deeper toward the center over a semicircle from the outer periphery. The second clutch member 17 has a through-hole 17b having a track-shaped cross section through which the mounting portion 3d of the spool shaft 3 passes. Second clutch member 1
7 is attached so that the concave portion 17a is located on the right side in FIG.

A thread is cut on the outer periphery of the cylindrical member 20, and a brake adjustment knob 22, which is threaded inside and serves as a braking force applying means, is screwed.

The flange portion 16 of the first clutch member 16
b between one surface and the inner wall 20a of the cylindrical member 20;
The brake material 23 is inserted. Similarly, a brake member 23 is inserted into the other surface of the flange portion 16b, and an ear washer 24 having the shape shown in FIG. 8 is inserted. A coil spring 25 is arranged between the ear washer 24 and the bottom of the brake adjustment knob 22.

The outer periphery of the eard washer 24 is engaged with two axial grooves 20 b provided in the cylindrical member 20,
Two protrusions 24a are provided to prevent rotation.
Further, the brake material 23 is formed of a friction material such as phosphor bronze, cork material, and wood.

In the above structure, when the clutch lever 10 is set to the off state when the fishing line is released,
When the step 13a of the jack member 13 moves toward the pinion gear 8, the first clutch mechanism 4 performs a clutch-off operation. That is, the pinion gear 8 moves rightward in FIG. 1 of the spool shaft 3, and becomes free in the rotation direction of the spool shaft 3, and releases the transmission of the rotation of the handle 5 to the spool shaft 3. Therefore, spool 2
Is in a free rotation state.

When the pinion gear 8 moves rightward, the coil spring 18 is compressed, and the second clutch member 1 is moved.
The spool 7 is urged by the spring force of the coil spring 18 and moves rightward of the spool shaft 3. Second clutch member 17
Moves rightward, the concave portion 21a engages with the projection 16c of the first clutch member 16, and the second clutch mechanism 15 enters the clutch-on state.

Therefore, when the spool 2 rotates freely due to the release of the fishing line, the second clutch member 17 and the first clutch member 16 rotate integrally with the rotation of the spool shaft 3.

At this time, a braking force is applied to the first clutch member 16 by the brake member 23, the coil spring 25, and the brake adjustment knob 22. Therefore, a resistance is given to the free rotation of the spool 2 by the braking force, and the excessive rotation of the spool 2 is suppressed, and the backlash of the fishing line can be prevented.

The braking force increases or decreases according to the degree of tightening of the brake adjustment knob 22. That is, the spring force of the coil spring 25 increases and decreases according to the degree of tightening of the brake adjustment knob 22, the pressing force of the brake material 23 against the first clutch member 16 via the ear washer 24 changes, and the braking force increases and decreases. It is.

Next, when the clutch lever 10 is set from the off state to the on state at the time of winding the fishing line, the step 13a of the jack member 13 moves in a direction away from the pinion gear 8, thereby causing the first clutch mechanism to move. 4 performs a clutch-on operation. That is, the pinion gear 8 is
The spool shaft 3 returns to the left in FIG. 1, is fixed in the rotation direction of the spool shaft 3, and transmits the rotation of the handle 5 to the spool shaft 3. Therefore, the spool 2 is in the driving rotation state.

When the pinion gear 8 returns to the left, the second clutch member 17 returns to the original position by the spring force of the coil spring 19, and the first clutch member 16 moves to the second position.
And the second clutch mechanism 15 is in the clutch off state.

Therefore, when the spool 2 is driven and rotated by the rotation of the handle 5 during winding of the fishing line, the brake is released and the spool 2 can be lightly driven by the handle 5 without resistance due to the braking force.

As described above, the embodiment of the present invention has been described. However, the present invention is not limited to this, and various modifications and applications are possible.

For example, in the embodiment, the first clutch mechanism 4 employs a manual clutch mechanism in which the clutch lever is manually turned on and off, but the clutch lever is manually operated only when the clutch is off. When the clutch is operated and the clutch is turned on, an automatic clutch mechanism known in the art may be used in which the clutch lever is automatically returned and turned on simply by rotating the handle in the forward direction.

The fishing reel of the present embodiment has a handle 5
However, the present invention can also be applied to an electric type in which a fishing line is wound around the spool 2 by a motor. Instead of switching the clutch on / off by the clutch lever 10, the drive member may be operated by a button switch to switch the clutch on / off.

Further, a structure may be employed in which both ends of the coil spring 18 are engaged with both the second clutch member 17 and the pinion. In this case, the coil spring 19 becomes unnecessary. Further, instead of the coil spring 25, another elastic member such as a leaf spring may be employed.

[0043]

According to the fishing reel of the present invention, the brake can be strongly applied when the spool is freely rotated at the time of releasing the fishing line, while the brake is applied when the spool is driven and rotated by the handle at the time of winding the fishing line. It can be released and the handle can be turned lightly. Also, sufficient braking can be applied to high-speed rotation such as 20,000 rotations of the spool per minute.
