Description

[Detailed description of the device] [Industrial applications]

The present invention relates to a drag device for fishing equipped with an automatic return clutch mechanism that automatically returns a spool in a free state to a winding state by rotating a handle.

[Prior art]

As a drag device for fishing reels, Shokai 61-12374
There is known a method in which it is provided on a drive shaft having a handle as seen in Japanese Patent Publication No. 62-204476, 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 device]

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. Since the rotation performance is poor, and the mechanism has both a drag function and a clutch function, the clutch cannot be operated 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 at the time of winding the fishing line, and a drag device is provided on a separate shaft from the drive shaft and the spool shaft. Japanese Patent Application Laid-Open No. Sho 58-51 discloses that the braking is performed only when the spool is reversely rotated.
It is known from publication No. 26. However, in this method, even if the fish is pulled beyond the set drag force during the winding of the fishing line, the winding action is preferentially connected directly, so the drag action does not work according to the tension due to the fish pulling, and the fishing line is cut. There is a problem. In view of these circumstances, the present invention not only improves the deficiencies of the conventional method, but also sufficiently exhibits the set drag performance even during the winding operation, thereby reliably preventing the fishing line from being cut during winding. An object of the present invention is to provide a fishing reel in which such a drag device and an automatic return clutch mechanism for a handle are compactly combined.

[Means for Solving the Problems]

In order to achieve the above object, the present invention rotatably fits a drive gear and a sun gear that mesh with a pinion engaged and disengaged by a clutch mechanism to a spool shaft on the axis of the drive shaft having a handle. A clutch return that attaches a planetary gear support body that supports a planetary gear to the drive shaft on the spool side in the axial direction of the drive gear so that the planetary gear support body rotates integrally with the planetary gear support body, and returns the clutch mechanism to the coupled state. Provided with a projection for engaging the planetary gear with the inner teeth formed on the inner periphery of the sun gear and the drive gear, supported by a support shaft projecting on the frame of the reel side plate, and adjusting the braking force with an adjusting knob. An interlocking gear formed on the sun gear is meshed with a free braking gear, and a reverse rotation stop mechanism is provided on the drive shaft. The drive gear may be directly rotatably fitted to the drive shaft, but may be rotatably fitted to a sun gear rotatably fitted to the drive shaft. It is more convenient if the braking gear is formed so that the braking force can be adjusted through the braking friction material and that the braking force can be adjusted in two stages of coarse adjustment and fine adjustment. Further, the structure can be simplified by integrally forming the reverse rotation preventing ratchet of the reverse rotation preventing mechanism on the planetary gear support.

[Action]

According to the present invention, when the drive shaft is rotated by the handle, the planetary gear support which is integral with the drive shaft is rotated, and the sun gear meshed with the planetary gear is engaged with the braking gear by the interlocking gear provided on the sun gear. Since the rotation of the planetary gear is stopped in accordance with the preset braking force, the planetary gear revolves around its own axis to rotate the drive gear, rotate the spool via the pinion, and wind the fishing line. When the pinion is disengaged from the spool shaft and the drive shaft is rotated by the handle in the spool-free state, the rotation of the planetary gear support causes the clutch return projection to engage with the clutch operating piece of the clutch mechanism and push it out. Then, the pinion is engaged with the spool shaft to automatically return to the spool winding state. However, when the spool load increases while the fishing line is being wound by the handle and exceeds the set braking force of the braking gear, the drive gear meshed with the pinion is fixed and the planetary gear revolves while revolving around the sun. Since the gear is rotated, the drag will slip even if the handle is wound up. If the load on the spool exceeds the set braking force of the braking gear when the handle is not wound, the drive shaft is stopped in the reverse direction by the stopper of the ratchet wheel. The sun gear does not rotate, the sun gear rotates through the pinion, the drive gear and the planetary gear against the braking force of the braking gear, and the spool is dragged and the fishing line is fed.

An embodiment of the present invention will be described with reference to the drawings. A pinion 5 is removably provided by a clutch mechanism 4 on a spool shaft 3 which is rotatably supported by a reel side plate 1 and to which a spool 2 is fixed. A drive shaft 7 having a handle 6 supported by the reel side plate 1 also has a reverse rotation preventing claw wheel 8 at its peripheral portion and a shaft 9'protruding outward.

Therefore, after setting the drag range with the fine adjustment knob 23, the desired drag force is set with the adjustment knob 22. When the drive shaft 7 is rotated by the handle 6 in this state, the planetary gear support 10 which is integral with the drive shaft 7 is rotated, and the sun gear 13 has its interlocking gear 12 meshed with the braking gear 19. The rotation is stopped in accordance with the braking force, and the planetary gears 9, 9 ... Revolve while revolving to rotate the drive gear 12, and the drive gear 12 rotates the spool 2 via the pinion 5 and the spool shaft 3 to rotate the fishing line. Wind up. When the spool load increases and exceeds the set braking force, the drive gear 12 meshing with the pinion 5 is fixed, and the planet gears 9 ... Since 13 is rotated, it will be in the drag slip state even during the handle winding operation. When a load larger than the drag force set on the braking gear 19 acts on the spool 2 in the state where the handle winding operation is not performed, the drive shaft 7 has the reverse rotation preventing ratchet wheel 8 as a stopper.
