Description

Detailed Description of the Invention [Industrial applications]

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

[Prior art]

As a drag device for fishing reels
There is known a method in which it is provided on a drive shaft having a handle as seen in Japanese Patent No. 374 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, the drag adjusting knob rotates with the drive shaft, so that the drag adjusting knob cannot be adjusted while the fishing line is being wound and the size of the drag adjusting knob is restricted. The latter method eliminates these defects, but the spool shaft is pressed in the axial direction and rotates while the pressing force is applied to the bearing, so the rotation becomes heavy and the spool becomes heavy due to the drag mechanism. Since the rotation performance at the time is inferior and it is a mechanism that combines the drag function and the clutch function,
There is a problem that the clutch cannot be operated independently and the operability is poor. 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 this method, even if the fish pulls more than the set drag force 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 is cut. There is a problem. 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]

According to the present invention, in order to achieve the above object, a handle rotating cylinder provided with a sun gear is rotatably fitted to a support shaft protruding outward from a frame of a reel side plate, and meshes with a pinion of a spool shaft. And a planetary gear is rotatably supported by a drive gear rotatably provided around the support shaft, and the planetary gear is provided to the sun gear and an inner tooth gear provided to rotate about the support shaft, respectively. The outer teeth provided on the outer peripheral portion of the inner gear are meshed with the braking gear whose braking force can be adjusted by the braking plate which is supported by the reel side plate and can be pressed into contact with the drag adjusting knob, and further the handle can be rotated. The cylinder is provided with a reverse rotation stop mechanism. The drive gear may be directly rotatably fitted to the support shaft, but may be rotatably fitted to a handle turning cylinder provided with a sun gear. The inner toothed gear having the outer tooth may be supported by a reel side plate, a drive gear, or a handle rotating cylinder so as to rotate about a support shaft.

[Action]

According to the present invention, when the handle rotating cylinder is rotated in the fishing line winding direction by the handle, the sun gear integrated with the handle rotates, and the inner tooth gear is stopped by the braking gear in accordance with the drag force preset. Therefore, the planetary gear revolves while rotating, and the revolving action causes the drive gear to rotate in the fishing line winding direction, and the fishing line is wound onto the spool via the pinion and the spool shaft. In such a winding state, when the load on the spool increases and exceeds the preset drag force of the braking gear, the drive gear meshed with the pinion is fixed and the planetary gear does not revolve but rotates on its own to rotate the inner gear. Is rotated to slip the braking gear against the drag force, and the drag is slipped even if the handle is wound up. When the load of the spool exceeds the set drag force of the braking gear due to the withdrawal of the fishing line when the handle is not wound, the drive gear reverses in the fishing line payout direction and the planetary gear also revolves in the same direction. However, since the sun gear does not rotate in reverse by the reverse rotation stop mechanism, the planetary gear rotates by the revolving action to rotate the inner tooth gear, causing the braking gear to slip and rotate against the drag force, and the spool is dragged and the fishing line is fed out. To be done.

【Example】

An embodiment of the present invention will be described with reference to the drawings. A pinion 5 is detachably provided on a spool shaft 4 which is rotatably supported by reel side plates 1 and 2 and to which a spool 3 is fixed. A drive gear 8 meshing with the pinion 5 is rotatably fitted to the base portion of a fixed or rotatable support shaft 7 projecting outward from the frame 6 and the outer end thereof has a handle. 9 is fitted with a handle rotating cylinder 11 provided with a sun gear 10 at the inner end thereof, respectively, and further provided with a claw wheel 13 with which a stopper claw 12 is engaged to prevent the reverse rotation thereof. is doing. Further, planetary gears 14, 14, ... Are rotatably supported on the side surface of the drive gear 8, and the planetary gears 14, 14 ,.

In the embodiment shown in FIG. 7, the drive gear 8 is rotatably fitted to the handle rotating cylinder 11 instead of being directly fitted to the support shaft 7. Therefore, after the drag force of the braking gear 19 is set to a predetermined value by the drag adjusting knob 21, the handle rotating cylinder 11 is rotated clockwise by the handle 9 as indicated by the solid line arrow in FIG. Sun gear 10 integrated with this

In such a winding state, when the load of the spool 3 increases and the set drag force of the braking gear 19 is exceeded, the drive gear 8 meshed with the pinion 5 does not rotate and the sun gear 10 moves to the clock. .. are rotated in the clockwise direction, whereby the planetary gears 14, 14 ... Do not rotate, but rotate in the counterclockwise direction to cause the braking gear 19 to slip clockwise in the clockwise direction against its drag force. Further, when a large load exceeding the drag force of the braking gear 19 acts on the spool 3 in a state in which the winding operation by the handle 9 is not performed, the drive gear 8 moves to the third position via the pinion 5.

【The invention's effect】

Since the drag device of the present invention utilizes the planetary gear mechanism, not only when the spool is rotated in the reverse direction, but particularly when the fishing line is wound up, the set drag performance can be sufficiently exerted to bring the drag slip state. Therefore, the cutting of the fishing line during the fishing operation can be reliably prevented, and the fishing operation can be performed easily and smoothly, and the handle operation does not become heavy and the casting performance does not deteriorate unlike the conventional method. Also, it has an excellent feature that it is easy to adjust the drag during fishing.
