Description

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

The present invention relates to an improvement in a transmission device for a fishing reel.

[Conventional technology]

In addition to the normal winding method, automatic transmission systems and manual transmission systems are known as methods for winding fishing lines.Although the automatic transmission system may seem convenient at first glance, it is difficult to use, especially for anglers, regardless of the fishing line winding load. Currently, the gear cannot be changed according to the will of the person.

[Problem to be solved by the invention]

In addition to the above-mentioned problems, the conventional internal transmission system has an operating body for drag adjustment and speed change on the handle shaft, as seen in Japanese Utility Model Application Publication No. 61-207168, which makes it difficult to operate during fishing operations. There is a defect in that the operating body is accidentally touched and the set gear change value changes, and there is also a defect in the mechanism that the handle shaft expands outward and becomes larger. In view of these current circumstances, it is an object of the present invention to provide a speed change device for a fishing reel that does not interfere with fishing operations and has a compact structure by improving the operational and mechanical defects of the automatic speed change system. That is. Another object of the present invention is to provide a transmission device for a fishing reel that allows the automatic transmission system to be easily converted to a manual transmission system so that the fishing line can be reeled in at high or low speed according to the will of the angler. It is.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention meshes a pinion for rotating a spool with a drive gear provided on a drive shaft, and a fishing line is wound 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 planetary gear pivotally supported at the front of the handle rotating barrel, and the inner gear is engaged with a sun gear provided on a drive shaft. A braking body, which is provided separately from the handle rotation barrel and whose braking force can be freely adjusted, is engaged with the provided engagement teeth. Further, by further providing a stopper pawl on the inner gear so as to be freely engaged and detached, the speed can be changed both automatically and manually. As means for adjusting the braking force of the braking body, there are two methods: one that uses the pressing force of a friction member, and the other that uses the additional force of a spring.The latter uses a dead point spring that further distributes the additional force. There are cases where a spring is used, and cases where a spring that is energized in one direction is used. 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 directly fixed to the drive shaft, and a one-sided clutch that engages the drive shaft and the handle rotation cylinder may be used. Bearing method, sliding engagement pin method, pawl engagement method, etc. can be used, and the inner gear is rotatably fitted to the handle rotation cylinder, drive shaft, and drive gear outside the side plate. be able to. [Operation] According to the present invention, when the handle is rotated in the fishing line winding direction with the stopper pawl not engaging the inner gear, the handle rotating cylinder rotates integrally, and the inner gear is prevented from rotating by the braking body. Therefore, the planetary gear revolves while rotating on its own axis, increasing the speed of the sun gear that is integrated with the drive shaft, and winds up the spool at high speed through the drive gear and pinion in turn. During this winding, if the winding load on the spool increases and exceeds the braking force set by the braking body, the planetary gear will no longer rotate or revolve, and the rotation of the handle in the fishing line winding direction will continue as it is. The rotation is transmitted to the drive shaft via the clutch, and the rotation is then automatically shifted to a low speed winding state via the drive gear and pinion, and when the winding load on the spool decreases, the speed is automatically or manually Then, the braking body prevents the rotation of the inner gear, and the speed is automatically changed to the high speed winding state again. Also, when the stopper pawl is engaged with the engagement teeth of the inner gear and the handle is rotated in the fishing line winding direction, the handle rotation cylinder rotates together with the handle, and the planetary gear revolves while rotating, increasing the number of sun gears. It rotates at high speed and winds up the spool at high speed through the drive shaft, drive gear, and pinion in sequence. Next, when the braking force on the inner gear of the brake body is released m;y and the stopper pawl is released from the locking teeth of the inner gear, the handle is rotated in the fishing line winding direction. The drive shaft is directly connected to the drive shaft via a clutch and rotates as a unit. The spool is wound up at low speed through a drive gear and a pinion in sequence.

【Example】

To explain the 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-sided clutch 9 using a needle bearing and has a handle 10. Planetary gears 12, 12, . The inside of the planetary gears 12, 12... is the drive shaft 4.
An inner gear 15 meshes with a sun gear 13 formed integrally with the inner gear 15 and has engagement teeth 14 on the outer periphery or side thereof.
It meshes with the The inner gear 15 is rotatably supported by a side plate 16, and its engaging teeth 14 are provided with a brake body 17 that meshes with the teeth and a removable stopper pawl 18, and the brake body 17 is attached to the frame. The friction member 2 is attached to the support shaft 19 supported by the
0 and screwed onto the support shaft 19.
The stopper pawl 18 is biased toward the engaging tooth 14 by a spring 22 and is engaged with and disengaged from the engaging tooth 14 by a switching operation piece 23. It is formed freely. An adjustment screw 24 of the friction braking member 5 is provided at the outer end of the support shaft 8, 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, when automatically changing the winding speed of the spool 1, the switching operation piece 23 disengages the stopper 18 from the engagement teeth 14, and the operation body 21 adjusts the frictional resistance of the brake body 17 in advance according to the fishing conditions. Set. After doing this, when the handle 10 is rotated in the fishing line winding direction, that is, in the clockwise direction in FIG.
Since the inner gear 15 is rotated integrally by the one-way clutch 9 and the rotation of the inner gear 15 is prevented by the brake body 17, the planetary gear 12 revolves while rotating, and the sun gear integrally formed on the drive shaft 4 rotates. 13 is rotated at increased speed, and this rotation winds up the spool 1 at high speed via the drive shaft 4, friction braking member 5, drive gear 6, pinion 3, and spool shaft 2. In this state, when the winding load on the spool increases due to the fish and becomes greater than the braking force of the brake body 17, the planetary gear 12 stops rotating and revolving, and the rotation of the handle 10 in the winding direction is limited to the handle rotation cylinder 11, The drive shaft 4 is directly connected to the handle rotation cylinder 11 through the one-way clutch 9 and rotates, and the inner tooth gear 15 rotates while meshing with the planetary gear 12 and following the rotation of the sun gear -7=13. At the same time, the braking body 17
is also rotated in conjunction with the inner gear 15, and is automatically shifted to a low speed winding state where it is not subject to the speed increasing action of the planetary gear mechanism.
When the winding load on the spool decreases, the speed is automatically changed to high speed winding again. Next, when performing manual gear shifting, as shown in FIGS. 2 and 3, the stopper pawl 18 is engaged with the engagement tooth 14 using the switching operation piece 23 to prevent rotation of the inner gear 15 in the fishing line winding direction. When the handle 10 is rotated in the fishing line winding direction in this state, the handle rotation cylinder 11 rotates integrally and the planetary gear 12 rotates.
revolves while rotating on its own axis to rotate the sun gear 13 at an increased speed, and this rotation can wind up the spool 1 at high speed via the drive shaft 4, drive gear 6, pinion 3, and spool shaft 2. In addition, in order to manually switch from high-speed winding to low-speed winding, first set the braking force of the brake body 17 to the minimum value with the operating body 21, and then use the switching operation piece 23 to move the stopper pawl 18 to the second
When the handle 10 is rotated in the fishing line winding direction with the engaging teeth 14 disengaged as shown by the chain line in the figure or in FIG. On the other hand, the inner gear 15 follows the rotation of the sun gear 13 in a state in which it is meshed with the planetary gear 12, and is not subjected to the speed increasing action by the planetary gear mechanism, and the rotation of the handle 10 is controlled by the drive gear 6, It is transmitted to the spool 1 via the pinion 3 and spool shaft 2, and winds up the spool 1 at a low speed. Instead of the needle bearing method of the embodiment, the one-way clutch 9 may use any one-way clutch such as an engagement pin sliding method or a pawl engagement method. In the embodiment shown in FIG. 5, the drive gear 6 is directly fixed to the drive shaft 4 without providing a drag mechanism, and the drive shaft 4 is pivotally supported on the frame 7. Further, in the embodiment described above, the stopper pawl 18 is urged against the engaging tooth 14 by the spring 22, but the stopper mechanism is not limited to this, and a known stopper mechanism may be used to force the stopper pawl 18 against the engaging tooth 14. 14 so that it can be freely engaged and detached. Furthermore, the inner gear 15 is rotatably fitted to the outer circumference of the handle rotation barrel 11 as shown in FIG. 6, or rotatably fitted to the drive shaft 4 as shown in FIG. As shown in FIG. 8, it can be rotatably fitted to the outer periphery of the drive gear 6 on the handle side. In all of the above embodiments, the braking force of the braking body 17 is provided by the friction member 2.
9 uses the force of the put point spring 26 as the braking force of the brake body 17. That is, as shown in FIG. 9, the stopper pawl 18 is separated from the engaging tooth 14, and the brake body 17, which is freely slidable by the guide 25, is moved to the engaging tooth 1 of the inner gear 15 by the dead point spring 26.
When the handle is rotated in the fishing line winding direction (clockwise direction) while the handle is energized so as to engage with the inner gear 15
Since rotation is prevented by the brake body 17, the planetary gear 12
The sun gear 1 revolves around its axis and is integral with the drive shaft 4.
3 is rotated at an increased speed to wind up the spool 1 at high speed in the same manner as in the previous embodiment. Next, in this state, when the winding load of the spool 1 increases and becomes larger than the applied force by the dead point spring 26 of the braking body 17, the dead point spring 26 of the braking body 17 is activated.
6, the handle 10 is energized to move away from the engagement teeth 14 as shown by the chain line, and the speed increasing effect by the planetary gear mechanism disappears, and the handle 10 is directly connected to the drive shaft 4 via the one-way clutch 9, and the spool 1 is Wind it up at low speed. Next, when winding up again at high speed, the rear end of the brake body 17 can be manually pressed against its biasing force to engage the engaging tooth 14 again. In this case, the biasing force of the put point spring 26 is It is configured so that it can be adjusted using the operating body 21. In addition, when performing high-speed winding and low-speed winding only by manual shifting, the same procedure as in the above embodiment is performed by engaging and disengaging the stopper pawl 18 from the engaging teeth 14 with the braking body 17 disengaged from the engaging teeth 14. It can be done with Further, in FIG. 10, a locking portion 27 and a protrusion 27' are provided to maintain the position of the brake body 17 separated from the engagement tooth 14, and the brake body 17 is urged by a spring 28 in the direction of engagement with the engagement tooth 14. When the winding load on the spool 1 increases and becomes larger than the urging force of the spring 28, the braking body 17 comes off from the engagement tooth 14 as shown by the chain line, and the locking portion 27 is moved to the protrusion 27' by the tensile force of the spring 28'. The brake body 17 is held apart from the engagement teeth 14 by engaging with the engagement teeth 14, and the speed increasing effect by the planetary gear mechanism is canceled as described above.When changing speed from low speed to high speed again, the brake body 17 must be manually engaged. The stop portion 27 is disengaged from the protrusion 27' and the braking body 17 is brought into engagement with the lock tooth 14 by the biasing force of the spring 28. 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 rotate integrally with the spool shaft 2, there is also a double bearing type reel in which the spool 1 is rotatably supported via a bearing, and a single bearing type reel. It can also be applied to fixed spool shafts in reels.
