Detailed Description of the Invention [Industrial applications]

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

2. Description of the Related Art An automatic transmission system that automatically shifts the spool winding speed according to the fishing line winding load seems to be convenient at first glance, but regardless of the fishing line winding load, the fisherman's will Therefore, there is an inconvenience that it is impossible to shift gears, and in such a case, it is necessary to use a manual shift method.

[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]

According to the present invention, in order to achieve the above object, a pinion for rotating a spool is meshed with a drive gear connected or integrally coupled through a friction braking member provided on a drive shaft, and the drive shaft is provided with a one-way clutch. A handle rotating cylinder that engages and rotates in the fishing line winding direction is provided, and the sun gear and the drive shaft that are rotatably provided on the drive shaft are integral with the planetary gear that is rotatably supported on the drive gear side of the handle rotating cylinder. The inner tooth gears that rotate in a desired manner are meshed with each other, and the stopper teeth are detachably provided on the locking teeth provided on the sun gear. The drive gear provided on the drive shaft may be a drag mechanism connected by a friction braking member or may be fixed to the drive shaft, and the one-way clutch that engages the drive shaft and the handle rotation cylinder is a needle. A bearing method, a slide engagement method of a retractable engagement pin, a claw piece 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 handle rotating 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 the inner tooth gear that rotates integrally with the drive shaft while rotating, and winds the spool at high speed through the drive shaft, the drive gear, and the pinion sequentially. . When the handle is rotated in the fishing line winding direction with the stopper claw disengaged from the locking teeth of the sun gear, the handle rotation cylinder is directly connected to the drive shaft via the one-way clutch and rotates integrally with the drive shaft. The spool is wound at a low speed through a drive gear and a pinion in order.

【Example】

An embodiment of the present invention will be described with reference to the drawings.
A drive gear 6 attached to a drive shaft 4 through a friction braking member 5 meshes with a pinion 3 which is detachably provided on a spool shaft 2 to which the drive shaft 4 is fixed. Further, it is fitted around the rotatable support shaft 8 so as to be prevented from rotating and freely movable in the axial direction. Further, the drive shaft 4 is provided with a handle rotating cylinder 11 which engages only in the fishing line winding direction and has a handle 10 via a one-way clutch 9 using a needle bearing, and the handle rotating cylinder 11 is provided. A planetary gear 12, 12, ... Is rotatably supported on the front part of the through a mounting member 11 '. The planetary gears 12, 12 ... Engage with the sun gear 13 rotatably fitted to the drive shaft 4 on the inner side, while the outer gear engages with the drive shaft 4 and the inner toothed gear 14 rotates integrally.
Further, a stopper claw 19 which is operated by an operating piece 17 axially supported by a side plate 16 and is biased by a spring 18 is engaged with and disengageable from a locking tooth 15 provided on the sun gear 13. An adjusting screw 20 of the friction braking member 5 is provided at the outer end of the support shaft 8 which is engaged with the drive shaft 6 by pressing the drive shaft 4 in the axial direction to press the friction braking member 5 into contact therewith. It is configured so that the frictional coupling force of can be adjusted strongly. Therefore, as shown in FIG. 2 or FIG. 3, the handle 10 is moved in the fishing line winding direction in a state in which the stopper claw 19 is engaged with the locking tooth 15 by the operation piece 17 to prevent the sun gear 13 from rotating in the fishing line winding direction. When rotated, the handle rotating cylinder 11 rotates integrally and the sun gear 13 is prevented from rotating by the stopper claws 19, so that the planetary gear 12 rotates while rotating the inner tooth gear 14 at an increased speed, and the rotation is driven. The spool 1 can be wound at high speed via the shaft 4, the drive gear 6, the pinion 3, and the spool shaft 2. Further, when the handle 10 is rotated in the fishing line winding direction with the operation piece 17 rotated as shown by the chain line in FIG. The sun gear 13 is directly connected to the drive shaft 4 via the directional clutch 9 and rotates integrally with the drive shaft 4.
Since it is released from 7, the rotation of the internal gear 14 follows the rotation of the internal gear 14 in a state of meshing with the planetary gear 12, and the planetary gear mechanism does not increase the speed, and the rotation of the handle 10 is changed to the drive gear 4, the pinion 3, It is transmitted to the spool 1 via the spool shaft 2 to wind the spool 1 at a low speed. The one-way clutch 9 according to the present invention is not limited to the Needle bearing method of the above-described embodiment, and for example, a slide engagement method of a retractable engagement pin or a claw piece engagement method having a sandwiching piece is used. Any one-way clutch can be used, such as In the embodiment shown in FIG. 6, the drive gear 6 is directly fixed to the drive shaft 4 and the drive shaft 4 is pivotally supported on the frame 7. Further, in the above-described embodiment, the stopper claw 19 is biased to the locking tooth 15 by the spring 18, but the stopper mechanism is not limited to this, and the stopper claw 19 can be locked by using a known stopper mechanism. It may be detachably formed on the fifteen. 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 for rotating the spool and the drive gear of the drive shaft are always kept in mesh with each other, and the drive shaft is provided with a handle rotating cylinder for engaging and rotating in the fishing line winding direction via a one-way clutch. A planetary gear rotatably supported on the front part of the handle rotating cylinder is engaged with a sun gear rotatably provided on the drive shaft and an inner toothed gear that rotates integrally with the drive shaft. By changing the speed of the spool at high speed or low speed by engaging and disengaging the stopper pawl that can be engaged with the stop tooth, the gear change operation can be performed smoothly and easily even when a winding load is applied and the meshing tooth surface. It has an excellent feature that it can be made compact without being damaged or worn and the transmission mechanism does not become large.
