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, single-bearing reels, and other fishing reels are generally equipped with a drag device that frictionally connects a spool and its winding rotation transmission system with arbitrary force.

This drag device slips and rotates the spool in the line payout direction from the frictional connection part when a large tensile force is applied to the fishing line due to a strong pull of the fish or a violent reversal, etc. when fighting a hooked fish. There are devices that prevent the fishing line from breaking by letting it out in the pulling direction. In addition, the drag knop, which determines the tensile strength for drawing out the line as described above, can be adjusted by rotating the drag nop in a direction that tightens or loosens it, depending on the thickness of the fishing line used, the expected pulling 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 linings stacked in the axial direction of the spool shaft, within the pivot of the spool that is rotatably supported by a fixed spool shaft. 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)
It is designed to adjust.

[Problem to be solved by the invention]

In such conventional drag devices, the drag knob is simply screwed onto the spool shaft, so in order to set the drag force required for fighting the target fish from almost zero drag force, it is necessary to use the drag knob. must be rotated multiple times, and if the target fish and the thickness of the fishing line change, the operating rotation speed of the dragnop will also differ.

Therefore, by forming an instruction mark on the drag knob and a display scale on the spool or reel body, even if you look at the display scale indicated by the indicator mark on the drag knob, the indicator scale will not show the drag force when the drag knob is rotated. I can't tell if it's there or not. Moreover, when adjusting the drag force 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 two or three times from the practically suitable drag force setting range, so If the angler tries to set the force again, the angler must memorize the number of rotations of the drag knob, which makes the setting complicated and impractical, and it is easy to make setting errors and the line may not hit the target. There was a problem that problems such as disconnection occurred.

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 that matches the rotation amount of a drag knob.

[Means to solve the problem]

The drag display device for a fishing reel according to the present invention has a drag device that rotatably supports a spool on a shaft member provided on a reel body and frictionally connects the spool to the shaft member in a slip-rotatable manner. In the fishing reel, an internal gear is housed in a front end surface of a drag knob for adjusting drag force of the drag device so as to be relatively rotatable and is coupled to the shaft member in a non-rotating manner; a sun gear that rotates integrally with the dragnop; a planetary gear that meshes with the sun gear and internally meshes with the internal gear; a carrier that holds the planetary gear and revolves integrally with the planetary gear; The device includes a drag force display scale formed on either the carrier or the internal gear facing the carrier, and an indicator for indicating the drag force display scale.

[For production]

In the present invention, when the drag knob is rotated, the sun gear rotates in the same direction, and the planetary gear inscribed in the internal gear revolves around the sun gear while rotating, thereby controlling the amount of rotation of the drag knob. The carrier is rotated by decelerating the rotation amount and converting it into a rotation amount for displaying the drag force, which is proportional to the rotation amount.

Therefore, by looking at the display scale indicated by the indicator as the carrier rotates, it is possible to accurately display the drag force according to the amount of rotation of the drag knob.

In FIG. 2, reference numeral 7 denotes a spool shaft that is supported on the reel body 1 coaxially with the support shaft of the rotor 3 so that it cannot rotate but can reciprocate in the axial direction. A central shaft hole 8a of a spool 8 around which a fishing line (not shown) is wound is rotatably fitted into the occluded shaft portion 7a, and this spool 8 is attached to the rear end of the omitted circular shaft portion 7a. It is restricted from moving in the direction of the rotor 3 by the fixed receiving member 9. Further, on the front surface of the spool 8, a drag device 10 is provided that applies a predetermined drag force to the spool 8 by frictionally coupling the spool 8 to the occluded shaft portion 7a.
is installed.

The drag device 10 is located in a cylindrical hole 8b formed on the front side of the spool 8 concentrically with the center shaft hole 8a, and is connected to the inner peripheral surface of the cylindrical hole 8b so as not to rotate relative to it, and is connected to the occluded circular shaft portion of the spool shaft 7. The first drag washer 11 is fitted in a relatively rotatable manner to the spool shaft 7, and the second drag washer 11, which is in a cap shape and a flat plate shape, is fitted in a free state to the cylindrical hole 8b and is fitted in a relatively unrotatable manner to the occluded circular shaft portion 7a of the spool shaft 7.

At the same time, a male threaded portion 15 is integrally provided at the tip of the partially circular shaft portion 7a protruding outward from the cylindrical hole 8b so as to coincide with the axis, and a drag adjustment nut 16 is screwed into this male threaded portion 15. has been done. A drag knob 17 is spline-fitted to the outer periphery of the drag knob 16 so that it cannot rotate relative to the drag knob 16, and a cap-shaped second drag washer 12a is attached to the end surface of the drag knob 17 on the nut-fitting side. A pressing member 18 is fixed together with a screw 19, and a compression spring 20 for adjusting the drag force is interposed between the pressing member 18 and the nut 16. Therefore,
Rotate the drag knob 17 left and right to tighten the nut 16,
When adjusted in the loosening direction, the spring pressure of the spring 20 applied to the washer group via the pressing member 18 changes, and the drag force on the spool 8 is adjusted. Also,
A spring member 21 for moderation is attached to the pressing member 18 and passes through the pressing member 18 in the radial direction, and the outwardly projecting end of the spring member 21 is attached to the inner periphery of the cap-shaped second drag washer 12a at a predetermined pitch. By resiliently engaging with the formed corrugated portion 12a+, the rotational operation of the drag knob 17 is controlled.

1 to 5, reference numeral 22 denotes a drag display mechanism that is assembled to the front surface of the drag knob 17 and displays a drag force proportional to the amount of rotation of the drag knob 17. A dish-shaped internal gear 24 is fitted in a cylindrical hole 17a formed concentrically with the cylindrical hole 17a so as to be relatively rotatable therein, and is non-rotatably coupled to a circular pin 23 whose center portion protrudes from the tip of the male threaded portion 15. , a plurality of planetary gears 25 that roll while inscribed inside the internal gear 24 , a ring-shaped carrier 26 that rotatably supports these planetary gears 25 at a predetermined angular position, and the internal gear 24 . A ring-shaped cover 2 is fitted onto the outer peripheral edge of the internal gear 24 and holds each planetary gear 25 so that it does not come out from inside the internal gear 24.
7, a cap-shaped connecting body 29 having a sun gear 28 located at the center of the internal gear 24 and meshing with each of the planetary gears 25 and rotating together with the drag knob 17; The carrier 26 and the internal gear 24 are connected to the dragnop 1.
cylindrical hole 17a so that it does not fall out from inside the cylindrical hole 17a of 7.
A transparent cover 30 is fixed to the opening of the
The distal end of the connecting body 29 projects outward from the center hole 30a of the transparent cover 30 (see FIG. 5), and the outer periphery of the connecting body 29 has an inner side of the center hole 30a of the transparent cover 30. A retaining portion 32 (see FIG. 5) that engages and disengages from the uneven portion 31 (see FIG. 5) formed by the edge is formed,
Furthermore, a compression spring 33 interposed between the connecting body 29 and the bottom surface of the internal gear 24 urges the engaging portion 32 to constantly engage with the uneven portion 31. is connected to the drag knob 17 so that the rotation of the drag knob 17 can be transmitted to the connecting body 29, and when the retaining part 32 of the connecting body 29 is removed from the uneven part 31, the display mechanism 22 is set to zero by the rotation operation of the connecting body 29. It can be reset.

Further, on the surface of the ring-shaped carrier 26, there is a scale 34 that displays a drag force proportional to the amount of rotation of the drag knob 17.
This display scale 34 is formed over the entire circumference of the carrier 2.
Drag force corresponding to two or three rotations of the drag knob 17 from the minimum value (drag force is almost zero) to the maximum value can be displayed within one rotation of the drag knob 17. Furthermore, on the surface of the ring-shaped cover 27 located around the outer periphery of the carrier 26, an indicator mark 35 for indicating the drag indicator scale 34 is formed.

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

When setting the drag force, first rotate the drag knob 17 to a certain extent in the tightening direction (direction of arrow A in FIG. 3), and apply the accompanying spring pressure of the compression spring 20 to the laminated washer group via the pressing member 18. As a result, the laminated washer group is pressed against the bottom surface of the cylindrical hole 8b of the spool 8. Thereby, the drag washers 11, 12a, and 12b are frictionally connected by the lining washer 13, and the spool 8 is placed in a state where a small drag force is provided to the spool shaft 7 so that it does not rotate freely.

Once the drag device 10 is preloaded in such a state, the connecting body 29 is pressed in the direction of arrow B in FIG.
The retaining portion 32 is removed from the uneven portion 31 and the connecting body 29 is separated from the transparent cover 30.

Then, by rotating the connecting body 29 to the left or right while maintaining this separated state, the carrier 29 including the planetary gear 25 is
is rotated planetarily to align the "0" position of the display scale 34 with the indication mark 35. When the alignment of the scale "0" is completed, the pressing force on the connecting body 29 is released, the connecting body 29 is returned to the state shown in FIG. 1 by the spring 33, and the retaining portion 32
is engaged with the uneven portion 31, and the connecting body 29 is attached to the transparent cover 30.
join to.

Next, when setting the zero-set drag device 10 to a drag force according to the thickness of the fishing line wound on the spool 8 and the target fish, the drag nop 17 is rotated in the six directions shown by the arrows in FIG. Then, since the coupling body 29 and the sun gear 28 also rotate in the same direction, the planetary gear 25 meshing with the sun gear 28 rotates in the direction of the dashed arrow in FIG. 3. At this time, the planetary gear 25 is meshed with the fixed internal gear 24, so the planetary gear 25 revolves around the sun gear 2 while rotating, and at the same time the carrier 26 holding the planetary gear 25 is rotated as shown in FIG. Rotate it in the direction of arrow C.

At this time, since the rotation of the drag knob 17 is decelerated by the planetary motion of the planetary gear 25, the amount of rotation of the carrier 26 varies depending on the number of teeth of the sun gear and the planetary gear, and the diameter of the internal gear. The amount of rotation is less than a fraction of the amount of rotation. That is, the rotation amount is converted into a rotation amount for displaying the drag force which is proportional to the rotation amount.

Therefore, as the drag knob 17 is rotated, an arbitrary numerical value on the display scale 34 on the carrier 26, which rotates at a reduced speed, can be set using the instruction mark 35.
, the scale value indicated by the instruction mark 35 becomes a drag force proportional to the amount of rotation of the drag knob 17. That is, it is possible to set the drag force simply by aligning the display scale 34 on the carrier 26, which is being rotated at a reduced speed, with the direction mark 35 on the rotating side.Moreover, the drag force can be set by adjusting the drag force to this setting value. It is no longer necessary to pay attention to the conventional adjustment operation and memorize the rotation amount, such as how much the rotation amount must be manipulated, and the angler can adjust the drag drag he wants without paying attention to the rotation amount of the drag knob 17. setting.

Adjustments can be made easily and quickly.

In addition, the amount of rotation of the drag knob 17 is decelerated, and the display scale 34
Since the drag force can be displayed according to the amount of rotation of the drag knob within one rotation of the carrier 26 having a In addition, when resetting the drag lever which has been set to -degrees, it is possible to easily do so by simply rotating the drag knob 17 so that the setting scale matches the instruction mark 35.

Furthermore, since the display scale 34 displays the drag force proportional to the amount of rotation of the drag knob, the drag knob may be loosened too much due to the adjustment claw of the amount of rotation of the knob as in the past.
Prevents over-tightening.

It should be noted that the drag force display method of the present invention is not limited to the spinning reel as shown in the above embodiment, but can of course be applied to single bearing reels (fly reels) and the like.

〔Effect of the invention〕

As described above, according to the present invention, the sun gear that rotates integrally with the spool and the drag knob of the drag device assembled to the shaft thereof, the planetary gear that meshes with the sun gear, and the planetary gear are inscribed in the drag knob of the drag device assembled to the spool and its shaft. A meshing internal gear is incorporated, the amount of rotation of the drag knob is decelerated by the above gear mechanism, the amount of rotation is converted to the amount of rotation for displaying the drag force proportional to this, and the amount of drag is displayed using this converted rotation amount. Therefore, the angler can easily and quickly set the desired drag without worrying about the amount of rotation of the drag knob, and the drag that matches the amount of rotation of the drag knob can be accurately displayed.
