Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to an improvement in a transmission device for a fishing reel. 1. Prior Art An automatic transmission system that automatically changes the winding speed of the spool according to the winding load of the fishing line may seem convenient, but it is difficult for anglers to change the winding speed regardless of the fishing line winding load. There is an inconvenience that it is not possible to change the speed according to one's will, and in such cases, the current situation is that a manual speed change method must be used.

[Problem to be solved by the invention] However, the conventional manual transmission system
As seen in Publication No. 779, the high-speed drive gear and low-speed drive gear on the handle shaft are switched so as to mesh with the high-speed or low-speed pinion on the spool shaft, and each switching operation causes the high-speed and low-speed drive gears to mesh with the high-speed or low-speed pinion on the spool shaft. Since the drive gear and the pinions for high and low speeds mesh from a separated state, the meshing operation cannot be performed smoothly under load, and the tooth profile is easily scratched and worn, and the structure is also large. SUMMARY OF THE INVENTION An object of the present invention is to provide a speed change device for a fishing reel that improves the deficiencies of the manual speed change system, allows smooth and easy switching operations, and prevents tooth profile from being damaged or worn. [Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention meshes a pinion for rotating a spool with a drive gear provided on a drive shaft, and also winds up a fishing line on the drive shaft via a one-way clutch. A handle rotating barrel is provided which engages and rotates in a direction, and a sun gear provided on a drive shaft and an inner gear are meshed with a planet gear pivotally supported at the front of the handle rotating barrel, and the inner gear is further engaged with a sun gear provided on a drive shaft. A stopper pawl is removably provided on the engaging teeth provided on the holder. The drive gear provided on the drive shaft may be a drag mechanism connected by a friction braking member, or the drive gear may be fixed to the drive shaft, and the one-way clutch that engages the drive shaft and the handle rotation tube may be a bearing. A method such as a slide method of an engagement bottle, a method of engaging a claw piece, etc. can be used.

[Effect]

In the present invention, when the handle is rotated in the fishing line winding direction with the stopper pawl engaged with the locking teeth of the inner gear, the handle rotation cylinder rotates together with the handle, and the planetary gear rotates on its own axis while increasing the sun gear. It rotates at high speed and winds up the spool at high speed through the drive shaft, drive gear, and pinion in sequence. In addition, when the handle is rotated in the fishing line winding direction with the sut bar pawl disengaged from the locking teeth of the inner gear, the handle rotation cylinder is directly connected to the drive shaft via a one-way clutch and rotates integrally with the drive shaft. , a drive gear and a pinion in order to wind up the spool at low speed.

To explain an embodiment of the present invention with reference to the drawings, the spool 1
A drive gear 6 attached to a drive shaft 4 via a friction braking member 5 meshes with a pinion 3 which is detachably provided on a spool shaft 2 to which a spool shaft 2 is fixed. The support shaft 8 is rotatably or non-rotatably fitted to the rotatable support shaft 8 in the axial direction. Further, the drive shaft 4 is provided with a handle rotation tube 11 which engages and rotates only in the fishing line winding direction via a one-way clutch 9 using a needle bearing and has a handle 10. Planetary gears 12, 12, . . . are rotatably supported on the front part of the shaft. 13 = The inside of the planetary gears 12, 12... is the drive shaft 4.
The inner gear 1 meshes with a sun gear 13 formed integrally with the inner gear 1, while the outer side has outer periphery or side locking teeth 14.
5, and the inner gear 15 is in mesh with the side plate 16.
A stopper pawl 19 is rotatably supported by the locking tooth 14, and is removably engaged with a stopper pawl 19 operated by an operating piece 17 pivotally supported by a side plate 16 and energized by a spring 18. Further, an adjustment screw 2 of the friction braking member 5 is attached to the outer end of the support shaft 8.
0 is provided so that the frictional coupling force of the drive gear 6 with the drive shaft 4 can be adjusted to be strong or weak. Therefore, as shown in FIG. 2, when the handle 10 is rotated in the fishing line winding direction while the stopper pawl 19 is engaged with the locking tooth 14 by the operation piece 17 to prevent the inner gear 15 from rotating in the fishing line winding direction, The handle rotation cylinder 11 rotates integrally, and the planetary gear 12 rotates on its own axis while increasing the speed of the sun gear 13. The rotation rotates the spool 1 via the drive shaft 4, drive gear 6, pinion 3, and spool shaft 2. It can be rolled up at high speed. Further, when the handle 10 is rotated in the fishing line winding direction with the stopper claw 19 disengaged from the locking tooth 14 as shown by the chain line in FIG. While directly connected to the shaft 4 and rotating integrally, the inner gear 15 follows the rotation of the sun gear 13 while meshing with the planetary gear 12 and is not subject to the speed increasing action of the planetary gear mechanism, so that the handle 10 The rotation is transmitted to the spool 1 via the drive gear 4, pinion 3, and spool shaft 2, and the spool 1 is wound up at low speed.

Further, in the embodiment described above, the stopper claw 19 is urged against the locking tooth 14 by the spring 18, but the stopper mechanism is not limited to this, and a known stopper mechanism is used to force the stopper claw 19 against the locking tooth 14. 14 so that it can be freely engaged and detached. The inner gear 15 may be rotatably fitted to the outer periphery of the handle rotation barrel 11 as shown in FIG. 9, or may be rotatably fitted to the drive shaft 4 as shown in FIG. As shown in FIG. 11, it can be rotatably fitted to the outer periphery of the drive gear 6 on the handle side. However, in the above embodiment, the spool 1 is connected to the spool shaft 2.
Although we have explained the case where the spool 1 is fixed to the spool shaft 2 so as to rotate integrally, there is also a double bearing type reel in which the spool 1 is rotatably supported via a bearing on the spool shaft 2, and a single bearing type reel. It can also be applied to a fixed spool shaft in a reel. Effects of the Invention 1 In the present invention, a pinion that rotates the spool and a drive gear of a drive shaft are always kept in mesh with each other, and a handle is provided on the drive shaft that is engaged and rotated in the fishing line winding direction via a one-way clutch. A rotating barrel is provided, and a planetary gear pivotally supported on the front part of the handle rotating barrel is meshed with a sun gear provided on the drive shaft and an inner gear having locking teeth, which can freely engage with the locking teeth. By engaging and disengaging the stopper pawl, the spool can be wound at high or low speeds, so even when a winding load is applied, the speed change operation can be performed smoothly and easily, and the meshing tooth surfaces are not damaged or worn. Moreover, it has an excellent feature that the transmission mechanism can be made compact without increasing its size.
