Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drag display device for a fishing reel.

[Conventional technology]

Spinning reels and other fishing reels are equipped with a drag device that frictionally connects the spool and its winding rotation transmission system with arbitrary force.

This drag device slips and rotates the spool from the frictional connection part in the line payout direction when a large tensile force is applied to the fishing line due to a strong pull or violent reversal of the fish, such as when fighting a hooked fish. This prevents the fishing line from breaking by letting it out in the pulling direction. Additionally, the drag force, which determines the tensile strength for line reeling out, is adjusted by tightening or loosening the drag knob depending on the thickness of the fishing line used, the expected pull strength of the target fish, etc. Ru.

Conventionally, a fishing reel having a drag device as described above is known from Japanese Utility Model Application Publication No. 48-50592.

In the case of a front-type fishing reel, the drag device of this type of fishing reel includes a plurality of drag washers and a plurality of drag washers stacked in the axial direction of the spool shaft. lining washer and
It is equipped with a drag knob screwed onto the tip of the spool shaft and a compression spring interposed between the drag knob and the laminated drag washers.The drag knob is rotated in the direction of tightening or loosening to adjust the tightening force on the laminated washers. By adjusting the frictional coupling force between the spool and the spool shaft, the driving torque of the spool in the line payout direction, that is, the drag force (line pulling output) is adjusted.

[Problems to be Solved by the Invention] In such conventional drag devices, the drag knob is simply screwed onto the spool shaft, so it is difficult to apply drag force from almost zero to fighting the target fish. In order to set the desired drag force, the drag knob must be rotated multiple times, and as the target fish and the thickness of the fishing line change, the number of rotations of the drag knob will also vary.

Therefore, by forming an indication mark on the drag knob and a display scale on the spool or reel body, and looking at the display scale indicated by the indication mark on the drag knob, the indication scale indicates the drag force at which rotation of the drag knob. I can't tell if it's true or not. Moreover, when adjusting the drag knob according to the target fish and the thickness of the fishing line, it is common to adjust the drag knob by turning the drag knob 2 to 3 times from the practically suitable drag setting range. If the angler attempts to set the drag force again, the angler must memorize the operating rotation speed of the drag knob, making the setting complicated and impractical. There was a problem that the thread could be cut or pulled.

The present invention solves the above-mentioned problems, and makes it easy to set the drag force by rotating the drag knob.
To provide a drag force display device for a fishing reel capable of accurately displaying a drag force matching the rotation amount of a drag knob.

[Means to solve the problem]

The drag force display device for a fishing reel according to the present invention is a fishing reel in which a drag device for applying a drag force to a spool rotatably supported on a reel frame body is mounted on the handle shaft side. a drag knob that is screwed onto the handle shaft to adjust the drag force; an internal gear that is accommodated in the drag knob so as to be relatively rotatable and fitted to the handle shaft so as to be movable in the axial direction; a sun gear that meshes with the sun gear and is inscribed in the internal gear; a planetary gear that holds the planetary gear and revolves integrally with the planetary gear and decelerates the rotation to a rotation amount proportional to the rotation amount of the drag knob. The apparatus is equipped with a rotating carrier member, a drag display scale formed on one side on the carrier member and an internal gear facing the carrier member, and an indicator for indicating the drag display scale.

[For production]

In the present invention, when the drag knob is rotated, the drag force of the drag device is adjusted, the sun gear rotates in the same direction, and the planetary gear inscribed in the internal gear rotates around the sun gear. The rotation amount of the drag knob is thereby decelerated, converted into a rotation amount for displaying drag force proportional to the rotation amount, and the carrier member is rotated.

Therefore, by looking at the display scale indicated by the indicator as the carrier member rotates, the drag force proportional to the amount of rotation of the drag knob can be accurately displayed within the range of one rotation of the carrier member.

is formed.

Next, the operation of this embodiment configured as described above will be explained.

When setting the drag force, first, the drag knob 22 is rotated to some extent in the tightening direction (in the six directions of arrows in FIG. A small drag force is applied to prevent free rotation.

Once the drag device 18 is preloaded in this state, the sun gear 31 is pressed in the direction of arrow B in FIG.
Separate from. While maintaining this separated state, the sun gear 3
1 to the left or right to decelerate and rotate the carrier member 29 to align the "0" position on the display scale 36 with the instruction mark 37. This completes the zero setting of the drag indicator mechanism 26.

Next, when setting the zero-set drag device 18 to a drag force according to the thickness of the fishing line wound on the spool 4 and the target fish, the drag knob 22 is rotated in the direction of arrow A in FIG. Then, the entire drag knob 22 moves in the direction of arrow C in FIG. 2 according to the screw lead of the threaded portion 11a of the handle shaft 11, increasing the pressing force applied to the laminated washer of the drag device 18 via the disc spring 25, and causing the laminated washer to increase. Drive gear 17 and handle shaft 11 by washer group
Increase the frictional bonding force between. As a result, the braking force applied to the spool 4 via the pinion gear 7 and the spool shaft 5 against rotation in the fishing line payout direction, that is, the drag force increases.

The amount of rotation of the drag knob 22 at this time is one rotation or more.

On the other hand, as the drag knob 22 is rotated in the direction of arrow A, the sun gear 31 integrated therewith is rotated in the same direction as the drag knob 22, so that it meshes with the sun gear 31 and the internal gear 27.
The planetary gear 28 inscribed in the planetary gear 28 rotates in the direction of the broken line arrow in FIG. 3 and also revolves in the direction of the arrow.
The carrier member 29 holding 8 is also rotated in the direction of the arrow.

At this time, since the rotation of the drag knob 22 is decelerated by the planetary motion of the planetary gear 28 and transmitted to the carrier member 29, the amount of rotation of the carrier member 29 is determined by the number of teeth of the sun gear 31 and the planetary gear 28, and the number of teeth of the internal gear. Although it varies depending on the diameter of the drag knob 22, it is less than a fraction of the amount of rotation of the drag knob 22. That is, the amount of rotation of the drag knob 22 is converted into the amount of rotation for displaying the drag force, which is proportional to the amount of rotation of the drag knob 22.

Therefore, if an arbitrary value on the display scale 36 on the carrier member 29, which rotates at a reduced speed as the drag knob 22 is rotated, is aligned with the instruction mark 37, the scale value indicated by the instruction mark 37 will be a drag force proportional to the amount of rotation of the drag knob 22. Become.

That is, the drag force can be set simply by aligning the display scale 36 on the carrier member 29, which is rotated at a reduced speed, with the instruction mark 37 on the stationary side.Moreover, the drag knob can be adjusted to adjust the drag force to this setting value. It is no longer necessary to pay attention to the conventional 1lfiff operation and memorize the amount of rotation of the drag knob 22. The drag force can be easily and quickly set and adjusted.

In addition, the amount of rotation of the drag knob 22 is decelerated, and the display scale 36 is
Since the drag force corresponding to the amount of rotation of the drag knob can be displayed within one rotation of the carrier member 29 having the
You can know the setting status of the drag force over a wide range from the minimum value to the maximum value just by looking at the display scale indicated by the setting scale. This can be easily done by simply rotating the drag knob 22 so that it aligns with the mark 37.

Furthermore, since the display scale 36 displays the drag force proportional to the amount of rotation of the drag knob 22, it is possible to prevent the drag knob from being excessively loosened or tightened due to incorrect adjustment of the amount of rotation of the drag knob as in the prior art.

FIG. 5 is a sectional view showing a second embodiment of the drag display device of the present invention.

In this embodiment, the drag knob 22 is formed of acrylic or other transparent material into a cap shape with a closed front end surface, and the center of the front plate 22b has a boss portion 22c formed to protrude inward. In addition to being screwed into the threaded portion 11a, a drag device 18 is provided within the drag knob 22.
The internal gear 27A, which also serves as a pressing body, is fitted so as to be relatively rotatable, and is held by a snap ring 39 to prevent removal.

Further, the internal gear 27A is fitted to the handle shaft 11 so as not to rotate.

A sun gear 31A is formed on the outer periphery of the boss portion 22c of the drag knob 22, and this sun gear 31A includes the following:
A plurality of planetary gears 28A inscribed in the internal gear 27A are meshed to enable planetary movement, and the planetary gears 28A are held by a ring-shaped carrier member 29A. Further, although not shown, a display scale that can be seen through the front plate 22b of the drag knob 22 is formed on the surface of the carrier member 29A, and an indication mark is formed on the end surface 27Aa of the internal gear 27A.

It goes without saying that the second embodiment configured in this way also provides the same effects as the first embodiment.

In the above embodiment, a case has been described in which the drag indicator scale is formed on the carrier member and the display mark is formed on the internal gear, but these may be reversed.

〔Effect of the invention〕

As described above, according to the present invention, the rotation of the drag knob that is rotatably screwed onto the handle shaft is controlled by the sun gear that rotates integrally with the drag knob and the sun gear that is relatively rotatable within the drag knob and is fitted to the handle shaft in a non-rotatable manner. A deceleration mechanism consisting of an internal gear and a planetary gear inscribed in the internal gear and meshing with the sun gear transmits the deceleration to a carrier member that revolves together with the planetary gear, and uses this carrier member to control the drag knob. The amount of rotation of the drag knob is converted to the amount of rotation used to display the drag force, and this converted amount of rotation is used to display the drag force, allowing anglers to easily obtain the desired drag force without being aware of the amount of rotation of the drag knob. , and can be set up quickly.
It has the effect of accurately displaying the drag force that matches the amount of rotation of the drag knob.
