Description

Detailed Description of the Invention [Industrial applications]

The present invention relates to an improvement in a fishing reel drag device.

2. Description of the Related Art As a drag device for a fishing reel, it is disclosed in Japanese Utility Model Laid-Open No. 61-123.
There is known a method in which it is provided on a drive shaft having a handle as seen in Japanese Patent Laid-Open No. 74-74, and a method in which it is provided on a spool shaft as seen in Japanese Utility Model Laid-Open No. 62-204476.

[Problems to be Solved by the Invention]

In the former method of the prior art, since the drag adjusting knob rotates with the drive shaft, the drag adjusting cannot be performed during fishing line winding, and the size of the adjusting knob is restricted, and the adjusting operation cannot be performed quickly and smoothly. However, the latter method eliminates these deficiencies, but the spool shaft is pressed in the axial direction and rotates with the pressing force applied to the bearing, so the rotation becomes heavier and the spool becomes heavier due to the drag mechanism. The rotation performance is poor, and since it is a mechanism that combines the drag function and the clutch mechanism, the clutch cannot function independently, and there are problems such as poor operability. Therefore, in order to improve both of these defects, the drive gear is directly connected to the drive shaft having the handle only when the fishing line is wound, and a drag device is provided separately from the drive shaft and the spool shaft so that the pinion and the gear of the spool shaft can be used. Japanese Patent Laid-Open No. 58-5 discloses a method of connecting and braking only when the spool rotates in reverse.
No. 126 publication. However, in such a method, even if the fish pulls more than the drag force set during winding of the fishing line, the winding action is prioritized and directly connected, so the drag action does not work according to the tension caused by the pulling of the fish, and the fishing line There is a problem of disconnecting. In view of these circumstances, the present invention not only improves the defects of the conventional method by utilizing the planetary gear mechanism, but also fully demonstrates the set drag performance even during the winding operation, and thus the fishing line during winding. It is an object of the present invention to provide a drag device capable of reliably preventing the cutting of the.

[Means for Solving the Problems]

In order to achieve the above object, the present invention supports a handle rotating cylinder having a reverse rotation stop mechanism coaxially with a spool shaft provided with a pinion, and an annular support rotatably supported around the spool shaft. A planetary gear is rotatably supported on the body, and the planetary gear is engaged with the pinion and an internal tooth gear provided on the handle rotation cylinder, respectively, and the gear provided on the outer periphery of the annular support is supported by the reel side plate and adjusted by a knob. A braking plate that can be pressed against by hand is engaged with a braking gear whose braking force is adjustable. The pinion can be formed so as to be engageable with and disengageable from the spool shaft by a clutch mechanism, or can be provided so as to be always directly connected to the spool shaft, and the drag force adjusting means of the braking gear controls the slip rotation. If so, any method can be adopted.

[Action]

According to the present invention, in the fishing line winding operation, when the handle rotating cylinder is rotated in the fishing line winding direction by the handle, the inner tooth gear is also rotated, but the annular support is held in a state where it is not rotated by the set drag force. Therefore, the planetary gear does not revolve around its own axis and rotates the pinion to wind the fishing line onto the spool via the spool shaft. In this state, if the load on the spool exceeds the drag setting force of the braking gear, the pinion of the spool shaft will not rotate, while the inner gear will rotate in the fishing line winding direction, so the planet gear will not rotate. While revolving in the same direction as the gear, it revolves to rotate the annular support and slip the braking gear meshing with it. When the load on the spool exceeds the set drag force of the braking gear when the handle is not wound, the pinion reverses in the fishing line feeding direction via the spool shaft, while the internal gear does not reverse with the reverse rotation stop mechanism. Therefore, the planetary gear revolves while rotating on its own axis, and the revolving action causes the annular support to rotate, causing the braking gear meshed therewith to slip and rotate against the drag force.

【Example】

An embodiment of the present invention will be described with reference to the drawings.
An inner end of a handle rotating cylinder 7 having a handle 6 supported by a reel side plate 5 coaxially with the spool shaft 2 and a pinion 4 which is detachably provided via a clutch mechanism 3 on the spool shaft 2 to which the spool shaft 2 is fixed. The internal gear 8 is integrated in the part
Is provided. An annular support 11 having a gear 10 on its outer periphery is rotatably supported on the frame 9 of the reel side plate 5, and the annular support 11 meshes with the pinion 4 and the internal gear 8 respectively. 12 ・ 12 ... are pivotally supported. Further, the frame 9 of the reel side plate 5 is provided with a braking shaft 13 having a circular cross-section with a tip portion formed in a small-diameter screw portion 13 ', and the braking shaft 13 has a recessed portion 14 protruding outward. The braking gear 15 meshing with the gear 10 is rotatably fitted, and the friction braking plates 16, 16 '... Are accommodated in the recess 14 of the braking gear 15 and screwed to the small diameter screw portion 13'. The drag adjusting knob 17 is configured so that the drag force of the braking gear 15 can be adjusted weakly. A claw wheel 19 that engages with the stopper claw 18 is fixed to the handle rotating cylinder 7. In the figure, 20 is a clutch plate of the clutch mechanism 3, 21 is a clutch operating slide plate, and 22 is a clutch lever. Is. Therefore, after the drag adjusting knob 17 adjusts and sets the drag force of the braking gear 15, the handle mechanism 6 rotates the handle rotating cylinder 7 in the fishing line winding direction while the pinion 4 is engaged with the spool shaft 2 by the clutch mechanism 3. Then, the inner tooth gear 8 integrally rotates in the clockwise direction as shown by the solid line in FIG.
Since the annular support 11 does not rotate due to the set drag force of the braking gear 15, the planetary gears 12, 12, ... Do not revolve, rotate in the clockwise direction to rotate the pinion 4 in the counterclockwise direction, and through the spool shaft 2. Wind the fishing line on the spool 1. When the load of the spool 1 exceeds the drag setting force of the braking gear 15 during this winding operation, the pinion 4 is not rotated and the inner tooth gear 8 is rotated clockwise by the handle rotation cylinder 7. Planetary gear 12.1
2 ... Revolves in the same direction while rotating in the clockwise direction to rotate the annular support body 11 in the clockwise direction and cause the braking gear 15 to slip and rotate in the counterclockwise direction. Also, when the winding operation with the handle is not performed,
When a load larger than the drag force set on the braking gear 15 is applied to the spool 1, the pinion rotates clockwise through the spool shaft 2 as shown by a chain line in FIG. Since the reverse rotation is prevented, the planetary gears 12, 12, ... Revolve in the clockwise direction while rotating in the counterclockwise direction, and by this revolution action, the annular support 11 is rotated in the clockwise direction and the braking gear 15 is rotated.
Is slip-rotated counterclockwise against the drag braking force. In the above embodiment, the pinion 4 is formed by the clutch mechanism so that it can be engaged with and disengaged from the spool shaft 2. However, the clutch mechanism can be omitted by always engaging the pinion 4 with the spool shaft 2.

【The invention's effect】

By utilizing the planetary gear mechanism, the drag device of the present invention can sufficiently exhibit the set drag performance not only when the spool is rotated in the reverse direction, but also when the fishing line is wound. It is possible to reliably prevent the fishing line from being cut during the fishing operation, and to easily and smoothly perform the fishing operation, without making the handle operation heavy and reducing the casting performance unlike the conventional method, and The drag adjustment operation during fishing is also easy. Further, according to the present invention, since the handle rotation cylinder is provided on the coaxial line with the spool shaft, the action of the sun gear in the planetary gear mechanism can be used also by the pinion of the spool shaft, and the conventional drive gear can be omitted. It has excellent characteristics that can be converted into
