Description

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 object, the present invention connects a planetary gear support cylinder, which 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. A drive gear that engages and rotates in one direction in the fishing line winding direction via a clutch is fitted to the drive gear, and the drive gear is meshed with the pinion of the spool shaft, and the outer side of the planet gear is the inner peripheral surface of the drive gear. The inner teeth formed on the inner side of the sun gear are engaged with the sun gear rotatably fitted on the drive shaft, and the stopper teeth are detachably provided on the locking teeth formed on the sun 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. The one-way clutch is a needle bearing system, a sliding engagement method of a retractable engagement pin,
A pawl engagement method or the like can be used.

[Action]

According to the present invention, when the handle is rotated in the fishing line winding direction while the stopper claw is in engagement with the sun gear locking tooth, the planetary gear support cylinder rotates integrally with the handle, and the sun gear has the locking tooth as the stopper claw. Since the rotation is blocked, the planetary gear rotates while rotating on its own, via the inner teeth of the drive gear to speed up the rotation of the drive gear, and the spool is wound at high speed through the pinion and the spool shaft in sequence. When the handle is rotated in the fishing line winding direction with the stopper claws disengaged from the locking teeth of the sun gear, the planetary gear support cylinder, which rotates integrally with the drive shaft, becomes the drive gear via the one-way clutch. It is directly connected and winds a spool at low speed through a pinion and a spool shaft in order.

【Example】

An embodiment of the present invention will be described with reference to the drawings.
A pinion 3 is provided on a spool shaft 2 to which is firmly attached, and a drive shaft 6 supported by a frame 4 and having a handle 5 is provided with a planetary gear 8 via a friction braking member 7.
A planetary gear support cylinder 9 having 8 ... Is provided, and the outer periphery of the planetary gear support cylinder 9 is engaged and rotated only in the fishing line winding direction via a one-way clutch 10 using a needle bearing and the pinion. 3, a drive gear 11 meshing with the drive gear 11 is provided, and inner teeth 12 are formed on the inner peripheral surface of the drive gear 11. The planetary gears 8 are engaged with the sun gear 13 rotatably fitted to the drive shaft 6 while the outer parts are engaged with the inner teeth 12 of the drive gear 11. A stopper claw 18 that is actuated by an operating piece 16 pivotally supported by the side plate 15 and is biased by a spring 17 is disengageably engaged with a locking tooth 14 provided on the sun gear 13, and is also driven. An adjusting screw 19 of the friction braking member 7 is provided at the outer end of the shaft 6 so that the frictional coupling force of the planetary gear support cylinder 9 with respect to the drive shaft 6 can be adjusted strongly. Therefore, as shown in FIG. 2 or 3, the handle 5 is moved in the fishing line winding direction in a state in which the stopper claw 18 is engaged with the locking tooth 14 by the operation piece 16 to prevent the sun gear 13 from rotating in the fishing line winding direction. When rotated, the drive shaft 6 rotates integrally and the sun gear 13 is prevented from rotating by the stopper pawls 18. Therefore, the planetary gear 8 rotates while meshing with the inner teeth 12 to rotate the drive gear 11 at an increased speed, The rotation allows the spool 1 to be wound at high speed via the pinion 3 and the spool shaft 2. Further, the operation piece 16 is rotated to rotate the stopper claw 18 as shown in FIG.
When the handle 5 is rotated in the fishing line winding direction with the engaging gear 14 disengaged, the planetary gear support cylinder 9 is directly connected to the drive gear 11 via the one-way clutch 10 and integrally rotates, while the sun gear is rotated. Since 13 is released from the stopper claw 18, it follows the rotation of the inner teeth 12 while meshing with the planetary gear 8 and is not in a state of being accelerated by the planetary gear mechanism. It is transmitted to the spool 1 via 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. Further, in the embodiment shown in FIG. 6, the planetary gear support cylinder 9 is directly fixed to the drive shaft 6 so as not to rotate. Further, in the above-mentioned embodiment, the stopper claw 18 is biased to the locking tooth 14 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 at 14. 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.

【The invention's effect】

According to the present invention, the pinion that rotates the spool and the drive gear of the drive shaft are always kept in mesh with each other, and a planetary gear support cylinder provided on the drive shaft is connected to the drive gear through a one-way clutch to wind the fishing line. Formed to engage and rotate in the taking direction,
A planetary gear rotatably supported by the planetary gear support cylinder is meshed with a sun gear rotatably provided on a drive shaft and an inner tooth formed on an inner peripheral surface of the drive gear, and is engaged with a locking tooth provided on the sun gear. Since the spool can be wound up at high speed or low speed by engaging and disengaging the adjustable stopper claw, the gear change operation can be performed smoothly and the meshing tooth surface may be damaged even when the winding load is applied. It has an excellent feature that it can be made compact without being worn and the transmission mechanism does not become large.
