Detailed Description of the Invention [Industrial applications]

TECHNICAL FIELD The present invention relates to an improvement of a transmission for a fishing reel.

[Prior art]

The automatic speed change method, which automatically changes the spool winding speed according to the fishing line winding load, seems to be convenient at first glance, but there is the inconvenience that the fisherman's will cannot change the speed regardless of the fishing line winding load. In such a situation, it is the current situation that the manual shift system must be used.

[Problems to be Solved by the Invention]

However, the conventional manual transmission system is the actual development 60-182
As can be seen in Japanese Patent Publication No. 779, the high speed drive gear and the low speed drive gear of the handle shaft are switched so as to mesh with the high speed or low speed pinion on the spool shaft, and high speed and low speed are switched for each switching operation. Since the drive gear and the pinions for high and low speeds mesh with each other from the separated state, the meshing operation in the loaded state cannot be performed smoothly, and there is a defect that the tooth profile surface is easily scratched or worn and the structure becomes large. SUMMARY OF THE INVENTION It is an object of the present invention to provide a transmission device for a fishing reel in which the defect of the manual transmission system is improved, the switching operation can be carried out smoothly and the tooth profile is not damaged or worn.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention connects a planetary gear support cylinder that supports a planetary gear to a drive shaft having a handle via a friction braking member or integrally connects the planetary gear support cylinder to the planetary gear support cylinder. And a drive gear meshing with the pinion of the spool shaft, a one-way clutch is interposed so that the drive gear engages and rotates in the fishing line winding direction, and the outer portion of the planetary gear is rotatable. The inner toothed gear is engaged with the sun gear formed on the drive gear, and the stopper tooth is detachably provided on the engaging tooth provided on the inner toothed gear. The planetary gear support cylinder provided on the drive shaft may be a drag mechanism connected by a friction braking member or may be fixed to the drive shaft while preventing the planetary gear support cylinder from rotating, and the planetary gear support cylinder and the drive gear are engaged. For the rotating one-way clutch, a needle bearing method, a slide engagement method of a retractable engagement pin, a claw piece engagement method, or the like can be used. The inner toothed gear may be rotatably supported by any of a side plate, a drive gear, and a planetary gear support cylinder. Further, the sun gear may have a tooth portion of the drive gear extended to serve also as the tooth portion. You can also

[Action]

According to the present invention, when the handle is rotated in the fishing line winding direction while the stopper claw is engaged with the locking tooth of the inner tooth gear, the drive shaft rotates integrally with the planetary gear support cylinder, and the inner tooth gear has its locking tooth. Since the rotation is blocked by the stopper claws, the planetary gear revolves around its own axis while rotating to rotate the sun gear at an increased speed, and the spool is wound at high speed through the drive gear and the pinion sequentially. When the handle is rotated in the fishing line winding direction with the stopper claws disengaged from the locking teeth of the internal gear, the planetary gear support cylinder that rotates integrally with the drive shaft is directly connected to the drive gear via the one-way clutch. The spool rotates integrally and winds the spool at low speed through the pinion.

【Example】

An embodiment of the present invention will be described with reference to the drawings.
A pinion 3 is provided on the spool shaft 2 to which is firmly attached, and a drive shaft 6 having a handle 4 and rotatably supported by a frame 5 has a planetary gear support cylinder via a friction braking member 7. 8 is fitted so as to rotate integrally,
.. are rotatably supported on the front portion of the planetary gear support cylinder 8. A drive gear 11 that engages with the pinion 3 and rotates only in the fishing line winding direction via a one-way clutch 10 using a needle bearing is provided on the outer peripheral portion of the planetary gear support cylinder 8. The inner portion of the planetary gears 9, 9 ... Engages with the sun gear 12 formed in the shaft cylinder portion of the drive gear 11, and the outer plate of the planetary gears 9, 9 ... The meshing inner tooth gear 14 meshes with each other, and the locking teeth 1 provided on the outer peripheral portion of the inner tooth gear 14
A stopper claw 18 that is actuated by an operation piece 16 pivotally supported by the side plate 13 and is urged by a spring 17 is disengageably engaged with the member 5. An adjusting screw 19 of the friction braking member 7 is provided at the outer end of the drive shaft 6 so that the frictional coupling force of the drive shaft 6 with respect to the planetary gear support cylinder 8 can be adjusted strongly. Therefore, as shown in FIG. 2 or FIG. 3, the operation shaft 16 engages the stopper claw 18 with the locking tooth 15 to prevent the inner tooth gear 14 from rotating in the fishing line winding direction, and the drive shaft 6 is wound. When rotated in the direction, the planetary gear support cylinder 8 integrally rotates and the inner tooth gear 14 is prevented from rotating by the stopper pawls 18. Therefore, the planetary gear 9 revolves while revolving to rotate the sun gear 12 at an increased speed. The rotation thereof allows the spool 1 to be wound at high speed via the drive gear 11, the pinion 3, and the spool shaft 2. When the drive shaft 6 is rotated in the fishing line winding direction with the operation piece 16 rotated as shown by the chain line in FIG. 2 or 4, and the stopper claw 18 is disengaged from the locking tooth 15, the planetary gear support cylinder 8 is While being directly connected to the drive gear 11 via the one-way clutch 10 to rotate integrally, the inner tooth gear 14 is released from the stopper pawl 18 and therefore follows the rotation of the sun gear 12 in a state of meshing with the planet gear 9. Then, the planetary gear mechanism does not receive the speed-up action, and the rotation of the drive shaft 6 is transmitted to the spool 1 via the drive gear 11, the pinion 3, and the spool shaft 2 to wind the spool 1 at a low speed. The one-way clutch 10 according to the present invention is not limited to the Needle bearing method of the above-described embodiment, but may be a slide engagement method of a retractable engagement pin or a claw piece engagement method. A one-way clutch can be used. In the embodiment shown in FIG. 5, the planetary gear support cylinder 8 is directly fixed to the drive shaft 6, and the drive shaft 6 is pivotally supported on the frame 5. Further, in the above-described embodiment, the stopper claw 18 is biased to the locking tooth 15 by the spring 17, but the stopper mechanism is not limited to this, and the stopper claw 18 can be locked by using a known stopper mechanism. It may be detachably formed on the fifteen. Further, the inner gear 14 is the drive gear 1 as shown in FIG.
It is also possible to rotatably support the shaft cylinder portion of No. 1 or rotatably support the planetary gear support cylinder 8 as shown in FIG.
Further, the sun gear 12 can also be made to function as the tooth portion of the drive gear 11 as shown in FIG. Therefore, in the above-described embodiment, the spool 1 is used with respect to the spool shaft 2.
Although the description has been given of the case where the spool is fixed so as to rotate integrally, the double-bearing type reel in which the spool 1 is rotatably supported by the spool shaft 2 via the bearing, and the single-bearing type reel is also used. It is also applicable to a fixed spool shaft in a reel.
