Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a transmission for a fishing reel.

[Prior art]

The conventional 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 the fisherman's willingness is to change gears regardless of the fishing line winding load. However, there is an inconvenience that you can not shift,
In such a case, the manual shift system must be used at present.

In the conventional manual transmission system, as in Japanese Patent Publication No. 18990/1980, the clutch is switched by the push / pull operation of the handle shaft to change the transmission paths of two sets of large and small gears for gear shifting,
As disclosed in Japanese Utility Model Publication No. 53-31276, gears are changed by changing the transmission direction by changing the rotation direction of the handle and combining the outer teeth and the first ratchet gear and the inner teeth and the second ratchet gear.

[Problems to be solved by the device]

In the former case, since two sets of large and small gear transmission paths are used, there is a drawback that the structure is bulky.

In the latter case, since gear shifting is performed by changing the rotating direction of the handle, there is a drawback in that operability is poor.

In view of the above-mentioned drawbacks, the present invention is not bulky and is compact, and it is possible to change gears by selecting rotation or rotation stop of the internal gear and rotating the handle in the same direction.

[Means for solving problems]

The present invention provides a structure for solving the above-mentioned problems, in which a fishing reel is wound around a handle drive shaft of a fishing reel in which a rotor is rotated by rotation of a handle to wind a fishing line on a spool through a one-way rotation clutch. Is provided with a handle rotating cylinder that engages with and rotates, and a sun gear provided on the drive shaft and an internal tooth provided outside the planetary gear are provided on a planetary gear that is rotatably supported at an end of the handle rotating cylinder on the housing side. The gist of the present invention is that the gears are engaged with each other, and the stopper teeth are releasably engaged with the engaging teeth provided on the internal gear.

〔Example〕

The present invention will be described below with reference to one embodiment shown in the drawings. FIG. 1 shows an example of the present invention applied to a spinning reel for fishing, and the transmission of the fishing reel is shown in FIGS. The handle rotation cylinder 3 is provided through the one-way rotation clutch 2 including the needle roller 10 and the clutch cylinder 11 and the bearings 12 and 13, and a plurality of handle rotation cylinders 3 are provided at the housing-side end of the housing 4 inside the housing 4. The planetary gears 14 are axially supported by shafts 15, respectively, and the planetary gears 14 are meshed with the sun gear 1a integrally provided on the handle drive shaft 1 and the internal teeth 5a of the internal gear 5, respectively. A stopper claw 6 is engaged with and disengageable from an engagement tooth 5b provided on the outer circumference.

A drive gear 16 is fixed to the handle drive shaft 1, a pinion 7a of a rotary shaft cylinder 7 is meshed with the drive gear 16, and a rotor 17 and a nut 18 are attached to the rotary shaft cylinder 7 protruding from the front part of the housing 4.
It is fixed at.

A spool shaft 19 is slidably fitted in the center hole 7b of the rotary shaft cylinder 7 in the front-rear direction, and a spool 20 is attached to the front end of the spool shaft 19.

The one-way rotation clutch 2 is configured such that the handle drive shaft 1 is engaged and rotated when the handle rotating cylinder 3 is rotated in the fishing line winding direction.

The handle rotating cylinder 3 is supported by the housing 4 via a bearing 21, and the other end of the handle drive shaft 1 is supported by the lid 8 via a bearing 22.

A shaft cover 23 is fitted to the outer circumference of the handle turning cylinder 3, and a handle 24 is fitted to the outer circumference of the handle turning cylinder 3 with a cap nut 25 screwed to the outer circumference.

A cylindrical portion 5c of the internal gear 5 is rotatably supported by the housing 4.

The stopper claw 6 is supported by a shaft 26 supported by the housing 4 and the projecting portion 8a of the lid 8, and the internal gear 5 is supported by a winding spring 27.
Biased to the side.

The engaging portion 6a of the stopper claw 6 is releasably engaged with the engaging tooth 5b of the internal gear 5, and the operating portion 6b is exposed to the cam surface 9a of the operating body 9 fixed to the switching knob 28.

The operation of the speed change device of the fishing reel is such that when the handle 24 is rotated with the stopper claw 6 locked to the engaging tooth 5b of the internal gear 5 shown in FIG. Tube 3
And the shaft 15 of the planetary gear 14 is rotated.

Since the internal gear 5 is prevented from rotating by this rotation, the planetary gear 14 rolls and revolves while rotating by the meshing with the internal gear 5a, and the rotation of the planetary gear 14 meshes with the planetary gear 14
It is transmitted to 1a by increased rotation.

The handle drive shaft 1 is rotated at high speed by the increased rotation of the sun gear 1a.

By this rotation, the drive gear 16 is rotated, the rotor 17 is rotated at high speed via the pinion 7a, and the fishing line is wound around the spool 20 at high speed.

At this time, in the one-way rotation clutch 2, the handle drive shaft 1 rotates faster than the clutch cylinder 11 rotates.
Is idled.

Next, when the switching knob 28 is rotated as shown in FIG. 5, the cam surface 9a of the actuating body 9 pushes the actuating portion 6b of the stopper claw 6 so that the engaging portion 6a moves from the engaging tooth 5b of the internal gear 5. The internal gear 5 is released and becomes rotatable.

When the handle 24 is rotated in this state, the handle rotating cylinder 3 and the shaft 15 of the planetary gear 14 are rotated.

At this time, since the internal gear 5 is rotatable, the planet gear 14 and the internal gear 5 are simultaneously rotated, and the rotation is transmitted at low speed to the sun gear 1a meshing with the planet gear 14 and the handle drive shaft 1.

At the same time, the rotation speed of the handle rotation cylinder 3 and the handle drive shaft 1
The rotation speed of the handle is the same, and the handle rotation cylinder 3 and the handle drive shaft 1 are directly connected via the one-way rotation clutch 2 and integrally rotated.

Drive gear 16 and pinion 7a due to low speed rotation of handle drive shaft 1
The rotor 17 is rotated at a low speed via, and the fishing line is wound around the spool 20 at a low speed.

When the transmission of the fishing reel is configured as described above,
Since the planetary gear 14 and the internal gear 5 fit within the same thickness, and the external gear 5 and the drive gear 16 can be formed to have substantially the same outer diameter, the housing 4 should not be bulky and should be compact. Can be done.

Further, since the handle 24 can rotate in the same direction at high speed and low speed, operability is not impaired.

Further, the stopper claw 6 is moved to the internal gear 5 by the rotation of the switching knob 28.
Since the rotation of the rotor 17 can be switched between the high speed rotation and the low speed rotation by engaging with and disengaging from the engaging teeth 5b, the gear shift operation can be smoothly and easily performed even when the winding load is applied.

Although a spinning reel for fishing is shown as a reel for fishing in the above description, it may be implemented on another reel such as a mask-type reel.

Further, as the one-way rotating clutch 2, a one-way rotating clutch including the needle roller 10 and the clutch cylinder 11 is shown, but a clutch having another known structure may be used.

Further, in the above description, the stopper claw 6 is biased to the internal gear 5 side by the winding spring 27, but it may be biased by another known configuration such as putting spring plates on both sides of the stopper claw 6 and sandwiching them.

[Effect of device]

Since the present invention is configured as described above, the planetary gear and the internal gear can be accommodated within the same thickness, and the internal gear can be formed to have substantially the same diameter as the outer diameter of the drive gear, so that the housing is not bulky. It can be configured compactly. Further, since the handle can rotate in the same direction at high speed and low speed, operability is not impaired. Also, the rotation of the switching knob engages and disengages the stopper claw with the engaging teeth of the internal gear to switch the rotation of the rotor between high-speed rotation and low-speed rotation, so even when a winding load is applied, gear shift operation is possible. It is possible to provide a speed change device for a fishing reel that has excellent practical effects such as smooth and easy operation.
