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 former method, since the drag adjusting knob rotates with the drive shaft, it is not possible to adjust the drag during fishing line winding and the size of the drag adjusting knob is restricted, so that the adjusting operation cannot be performed quickly and smoothly. The latter method eliminates these deficiencies, but the spool shaft rotates in the state of being pressed in the axial direction and the pressing force is applied to the bearing, so the rotation becomes heavier and the spool becomes heavier 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 brake cylinder is axially movably fitted to a fixed shaft projecting outward from a frame of a reel side plate, and a planetary gear is pivotally supported on the brake cylinder. A drive gear, in which a cylinder is rotatably fitted and which is provided with inner teeth meshing with a pinion of a spool shaft and meshing with the planetary gear, is provided so as to rotate around the fixed shaft,
A sun gear that meshes with the planetary gear is press-fitted to the braking cylinder via a braking member, and a drag adjusting knob for advancing and retracting the braking cylinder is provided on a fixed shaft. A stop mechanism is provided. The drive gear is provided so as to be fitted on the handle rotation cylinder so as to rotate about the fixed shaft, and the drive gear is fitted to the shaft cylinder portion of the sun gear fitted on the braking cylinder to center the fixed shaft. There are a case where it is provided so as to be rotated to and a case where it is provided so as to be directly rotated on the fixed shaft. As means for moving the brake cylinder forward and backward with respect to the fixed shaft, a drag adjusting knob is screwed on the outside of the fixed shaft and the brake cylinder is moved forward and backward by its rotation, or a drag formed on a cam formed on the outside surface of the brake cylinder. It is also possible to bring the adjusting knob into contact and move the rotating cylinder back and forth by a cam action by its rotation. A friction plate, a spring member, a spring plate, or the like can be used as the braking member that press-bonds the sun gear.

[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 meshed with the planetary gear that is rotatably supported by the handle stops in accordance with the braking force preset by the braking member. Therefore, while rotating in the fishing line winding direction, the fishing line is revolved and the drive gear is rotated through the inner teeth, and the fishing line is wound around the spool that rotates through the pinion and the spool shaft. When the load on the spool increases in such a winding state, the drive gear stops rotating and the handle rotating cylinder rotates in the fishing line winding direction, so the planetary gears that are rotatably supported rotate in the anti-winding direction. While revolving in the winding direction, the sun gear slips in the winding direction against the drag force of the braking member. Also, when the load exceeds the preset drag force of the sun gear due to the tension of the fishing line in the state where the handle is not wound, the drive gear is rotated in the anti-winding direction via the pinion. The inner teeth also rotate in the same direction, but the handle rotation cylinder does not rotate in the reverse direction due to the reverse rotation stop mechanism, so the planetary gears do not revolve, but rotate in the anti-winding direction and the sun gear slips in the winding direction against the drag force. Then the fishing line is paid out.

【Example】

An embodiment of the present invention will be described with reference to the drawings. As is well known, a pinion 5 is removably supported on a spool shaft 4 which is rotatably supported between reel side plates 1 and 2 and to which a spool 3 is fixed. On the other hand, a braking cylinder 8 having a pressing edge 8'is axially movably fitted to the fixed shaft 7 in a circular cross section protruding outward from the frame 6 of the reel side plate 1 and is fitted to the braking cylinder 8. A steering wheel rotating cylinder 11 having a planetary gear 9, 9 ... Supported on the inside and a handle 10 fixed on the outside is rotatably fitted, and the steering wheel rotating cylinder 11 is a drive gear that meshes with the pinion 5. 12 is rotatably fitted, and further the drive gear 1
2 is provided with inner teeth 13 with which the planetary gears 9, 9 ... Further, the inner side of the pressing edge 8'of the braking cylinder 8 is crimped by friction braking members 14, 14 ... And the planetary gears 9, 9 ,.
A sun gear 15 meshing with the fixed shaft 7 is fitted to the outer end of the fixed shaft 7, and the drag adjusting knob 16 is screwed to the outer end of the fixed shaft 7 so as to move the brake cylinder 8 in the axial direction. The sun gear 15 is configured to be fitted to the braking cylinder 8 by an arbitrary drag force by crimping 14, 14 ... And a stopper claw 17 for preventing reverse rotation is engaged with the handle rotating cylinder 11. A claw wheel 18 is provided. Therefore, after the drag adjusting knob 16 advances and retracts the braking cylinder 8 to preset the drag force of the sun gear 15 by the friction braking members 14, 14, the handle 10 is set in the fishing line winding direction as shown in FIG. When rotated in the clockwise direction, the planetary gears 9, 9, ..., which are pivotally supported by the handle rotation cylinder 11, revolve in the same direction while rotating clockwise in the clockwise direction as indicated by the solid arrow, and drive gears 12 through the inner teeth 13. It is possible to wind the fishing line by rotating the spool 3 in the clockwise direction to rotate the spool 3 through the pinion that meshes with the drive gear 12 and the spool shaft 4. However, when the load of the spool increases and the set drag force of the sun gear 15 is exceeded during such winding, the inner teeth 13 of the drive gear 12 do not rotate, while the handle rotation cylinder 11 By being rotated in the clockwise direction, the planetary gears 9, 9 ... Revolve in the clockwise direction while rotating in the counterclockwise direction to slip the sun gear 15 in the clockwise direction against the drag force. Further, when the spool 3 is rotated in the reverse direction by pulling out the fishing line without the winding operation by the handle 10, the drive gear 12 is rotated counterclockwise through the pinion 5 so that the inner teeth 13 are also rotated in the same direction. However, since the handle rotation cylinder 11 is prevented from rotating in the reverse direction by the stopper claws 17, the planetary gears 9, 9 ... Do not rotate, but rotate only in the counterclockwise direction and rotate the sun gear 15 in the clockwise direction against the drag force. The spool 3 is reversely rotated and the fishing line is operated. In the above embodiment, the fixed shaft 7 has a circular cross section and the brake cylinder 8 is fitted to prevent the brake cylinder 8 from rotating.
May be configured to be rotatable. The embodiment shown in FIG. 5 is a case where the drive gear 12 is rotatably fitted to the shaft cylinder portion formed on the sun gear 15, and
In the embodiment shown in the drawing, the drive gear 12 is directly rotatably fitted to the fixed shaft 7, and in FIGS. 7 and 8, a cam surface 8'is formed on the end surface of the braking cylinder 8. A protrusion 16 'provided on a drag adjusting knob 16 mounted on the fixed shaft 7 on the cam 8'.
An example is shown in which the brake cylinder 8 is moved forward and backward by abutting against.

EFFECTS OF THE INVENTION The drag device of the present invention utilizes the planetary gear mechanism to 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 up, so that the drag slip state is achieved. 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 becomes heavy as in the conventional method, and the casting performance is deteriorated. Also, it is easy to adjust the drag during fishing. In addition, the present invention has an excellent feature that the structure is simple and compact because the sun gear on the handle shaft cylinder also serves as the drag mechanism.
