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. Which meshes an internally rotating toothed gear, and an engaging tooth provided on the sun gear is engaged with a braking body which is provided separately from the handle rotating cylinder and has a steplessly adjustable braking force. Is. Further, by providing the engagement tooth of the sun gear with a stopper pawl so as to be engageable and disengageable, both automatic and manual gear shifting can be performed. The means for forming the braking force of the braking body so as to be adjustable steplessly include a method of utilizing the pressure contact force of the friction member by the operating body and a method of utilizing the urging force of the spring, and the latter is further urging force. There is a case where a dead point barrage that distributes is used and a case where a bar urging in one direction is used. The drive gear provided on the drive shaft may be a drag mechanism that is connected by a friction braking member or may be directly fixed to the drive shaft, and the one-way clutch that engages the drive shaft and the handle rotation cylinder is A bearing method, an engagement pin sliding method, a claw piece engaging 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 not engaged with the engaging teeth of the sun gear, the handle rotating cylinder is integrally rotated, and the sun gear is prevented from rotating by the braking body. Therefore, the planetary gear revolves while rotating on its own axis to rotate the inner gear integrally with the drive shaft at an increased speed, and the spool is wound at high speed through the drive shaft, the drive gear, and the pinion sequentially. If the winding load of the spool increases during this winding and the braking force set by the braking body is exceeded, the planetary gears will not rotate or revolve, and the rotation of the handle in the fishing line winding direction will remain as it is in the handle rotation tube, one direction. The rotation is transmitted to the drive shaft via the clutch, and its rotation is then automatically changed to the low-speed winding state via the drive gear and the pinion.
When the winding load on the spool decreases, the braking body automatically or manually blocks the rotation of the sun gear and automatically shifts to the high-speed winding state again. When the stopper claw is engaged with the engaging tooth of the sun gear and the handle is rotated in the fishing line winding direction, the handle rotating cylinder rotates integrally with the handle, and the planetary gear revolves while rotating to increase the inner tooth gear. It rotates at high speed and winds a spool at high speed through a drive shaft, a drive gear and a pinion in order. Next, when the handle is rotated in the fishing line winding direction with the braking force on the sun gear of the braking body being released and the stopper claw being disengaged from the locking teeth of the sun gear, the handle rotating cylinder is driven via the one-way clutch. It is directly connected to the shaft and rotates integrally, and the spool is wound at a low speed through the drive shaft, the drive gear, and the pinion sequentially.

【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 via a friction braking member 5 meshes with a pinion 3 which is removably provided on a spool shaft 2 to which a spool 1 is fixed. The drive shaft 4 is fixed to the rotatable support shaft 8 projecting from the frame 7 so as to be rotatable and axially fitted thereto. Further, the drive shaft 4 is provided with a handle rotating cylinder 11 which engages and rotates 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 In the front part of the planetary gear 12,
12 ... is rotatably supported. The planetary gears 12, 12, ... Engage with an inner toothed gear 13 provided on the outer side so as to rotate integrally with the drive shaft 4, while the inner side has engaging teeth 14 on the outer circumference or side portions. It also meshes with a sun gear 15 rotatably provided on the drive shaft 4. The engaging tooth 14 of the sun gear 15 is provided with a braking body 17 and a stopper claw 18 which can be engaged and disengaged at all times, and the braking body 17 is supported by a support shaft 19 supported by the frame 7 by a friction member.
It is formed so that the braking force can be freely adjusted by advancing and retracting the operating body 21 which is fitted through 20 and screwed to the support shaft 19, and the stopper claw 18 is directed toward the engaging tooth 14 by the spring 22. It is energized and formed so that it can be engaged with and disengaged from the engaging teeth 14 by the switching operation piece 23. An adjusting screw 24 of the friction braking member 5 is provided at the outer end of the support shaft 8, and the friction braking member 5 is pressed against the drive shaft 4 by pressing the drive shaft 4 in the axial direction so that the friction coupling force of the drive gear 6 is generated. It is configured to be adjustable in strength. Therefore, in order to automatically change the winding speed of the spool 1, the stopper 18 is disengaged from the engaging teeth 14 by the switching operation piece 23, and the frictional resistance of the braking body 17 is previously adjusted by the operating body 21 in accordance with the fishing conditions. Set. In this way, when the handle 10 is rotated in the fishing line winding direction, that is, the clockwise direction in FIG. 4, the handle rotating cylinder 11 is integrally rotated by the one-way clutch 9, and the sun gear 15 is rotated.
Since the rotation is blocked by the braking body 17, the planetary gear 12
Revolves around its own axis and rotates the internal gear 13 formed integrally with the drive shaft 4 at an increased speed. This rotation causes the drive shaft 4, the friction braking member 5, the drive gear 6, the pinion 3, and the spool shaft 2 to rotate. The spool 1 is wound up at a high speed via this. In this state, if the winding load of the spool increases due to the fish and becomes larger than the braking force of the braking body 17, the planetary gears
12 does not rotate or revolve, and the handle 10 rotates in the winding direction by rotating the handle shaft 11 and the one-way clutch 9 so that the drive shaft 4 is directly connected to the handle shaft 11. The planetary gear 12 meshes with the inner gear 13 and rotates in a state of following the rotation of the inner gear 13.
It rotates in synchronism with 15 and automatically shifts to a low-speed winding state in which the planetary gear mechanism does not accelerate, and when the spool winding load decreases, it automatically shifts to the high-speed winding again. . Next, when manual shifting is performed, the stopper claw 18 is engaged with the engaging tooth 14 by the switching operation piece 23 as shown in FIGS. 2 and 3 to prevent the sun gear 15 from rotating in the fishing line winding direction. When the handle 10 is rotated in the fishing line winding direction in this state, the handle rotating cylinder 11 integrally rotates and the planetary gear 12 revolves around its own axis to rotate the inner tooth gear 13 at an increased speed. The spool 1 can be wound at high speed via the drive gear 6, the pinion 3, and the spool shaft 2. Further, in order to manually switch from the high-speed winding to the low-speed winding, after the braking force of the braking body 17 is set to the minimum value by the operating body 21 in advance, the switching operation piece 23 is used to move the stopper claw 18 to the chain line in FIG. As shown in Fig. 4, handle with engaging teeth 14 disengaged
When 10 is rotated in the fishing line winding direction, the handle rotating cylinder 11 is directly connected to the drive shaft 4 through the one-way clutch 9 and integrally rotates, while the sun gear 15 is inwardly meshed with the planetary gear 12. Following the rotation of the toothed gear 13, the planetary gear mechanism does not increase the speed, and the rotation of the handle 10 is rotated by the handle rotating cylinder 1, the one-way clutch 9, the drive shaft 4, the drive gear 6, the pinion 3, and the spool. It is transmitted to the spool 1 via the shaft 2 and the spool 1 is wound at a low speed. The one-way clutch 9 uses a slide system of engagement pins instead of the needle bearing system of the embodiment,
Any one-way clutch can be used, such as using 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 above-described embodiment, the stopper claw 18 is formed with the ridge 22 to engage teeth.
However, the stopper mechanism is not limited to this, and a known stopper mechanism may be used to disengage the stopper claw 18 from the engaging tooth 14. In each of the above-mentioned embodiments, the braking force of the braking member 17 is applied to the friction member 20.
The pressure contact force of the brake body 17 is used in FIG.
It is shown that the urging force of the dead point spring 26 is used as the braking force of. That is, as shown in FIG. 6, the stopper claw 18 is disengaged from the engaging tooth 14 and the guide body 25 slidably attaches the braking body 17 to the engaging tooth 14 of the sun gear 15 by the dead point spring 26. When the handle is rotated in the fishing line winding direction (clockwise direction) in a biased state, the sun gear 15 is prevented from rotating by the braking body 17, so that the planetary gear 12 revolves around its own axis while rotating, and is integrated with the drive shaft 4. The inner tooth gear 13 is rotated at an increased speed to wind the spool 1 at high speed in the same manner as in the above embodiment. Next, in this state, when the winding load of the spool 1 increases and the load becomes larger than the urging force of the dead point spring 26 of the braking body 17, the braking body 17 crosses the dead point of the dead point spring 26 and acts as a chain line. It is urged to move away from the artificial teeth 14 and the speed increasing function of the planetary gear mechanism disappears and the handle 10
Is directly connected to the drive shaft 4 via the one-way clutch 9 and winds the spool 1 at a low speed. Next, when winding at a high speed again, the rear end of the braking body 17 may be manually pressed against the biasing force to engage the engaging tooth 14 again, and the biasing force of the dead point spring 26 in this case is One end of the spring 26 is engaged with the braking body 17 and the other end thereof is engaged with the operating body 21, respectively, and the operating body 21 can be adjusted by the strength of the urging force of the elastic 26. Further, when performing high-speed winding and low-speed winding only by manual shifting, the stopper claw 18 is disengaged from the engaging tooth 14 with the braking body 17 disengaged from the engaging tooth 14 in the same manner as in the above embodiment. Can be done at. Further, in FIG. 7, an engaging portion 27 for holding the separated position of the braking body 17 with respect to the engaging teeth 14 and a projection 27 'are provided and the braking body 17 is provided.
Is urged by the spring 28 in the direction of engaging the engaging teeth 14.
When the winding load of the spool 1 increases and becomes larger than the urging force of the spring 28, the braking body 17 is disengaged from the engaging teeth 14 like a chain line, and the engaging portion 27 is engaged with the protrusion 27 'by the pulling force of the spring 28'. The braking body 17 is held apart from the engaging teeth 14 in order to eliminate the speed increasing action of the planetary gear mechanism.When shifting from low speed to high speed again, the braking body 17 is manually locked by its locking portion.
The protrusion 27 'is disengaged from the protrusion 27' and is engaged with the locking tooth 14 by the urging force of the spring 28. The braking force of the braking body 17 can be freely adjusted by adjusting the urging force of the spring 28 by the operating body 21. In the above embodiment, the spool 1 is fixed to the spool shaft 2 so as to rotate integrally, but the spool 1 is rotatably supported on the spool shaft 2 via a bearing. The present invention can be applied to a double-bearing type reel as well as a fixed spool shaft in a single-bearing type reel.
