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 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 one rotation 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 or violent reversal of the fish, such as when fighting a hooked fish. , which 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 the front type, this kind of fishing reel drag device includes a plurality of drag washers and linings stacked in the axial direction of the spool shaft within a pivot portion of the spool that is rotatably supported by a fixed spool shaft. washer and
A drag knob screwed onto the tip of the spool shaft, and a compression spring interposed between the drag knob and the laminated drag washer, the drag knob being rotated in a tightening or loosening direction to adjust the tightening force on the laminated washer group; 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.

[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 from almost zero to the drag force required for fighting the target fish, The drag knob must be rotated multiple times, and if 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 decide what's going on. Moreover, when adjusting the drag force according to the target fish or the thickness of the fishing line, it is common to turn the drag knob 2 to 3 times from the practically suitable drag force setting range, so it is necessary to set it once. If the angler tries to set the drag force again, he or she must memorize the number of rotations of the drag knob, making the setting complicated and impractical. There was a problem in that troubles such as the threads being cut were caused.

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 fishing according to the present invention is provided in a fishing reel having a drag knob at the rear of the reel body for adjusting the drag force of a spool rotatably supported on the reel body. a cylindrical part rotatably supporting the center boss part of the drag knob; an internal gear formed on the inner wall of the cylindrical part concentrically with the center boss part of the drag knob; and an internal gear formed on the outer periphery of the center boss part of the drag knob. The sun gear meshed with this sun gear,
and a planetary gear inscribed in the internal gear, a drag force display body that holds the planetary gear, revolves integrally with the planetary gear, and decelerates and rotates to a rotation amount proportional to the rotation amount of the drag knob, and the drag force display. The reel body is equipped with a drag force display scale formed on one side on the surface of the reel body and an indicator section for indicating the drag force display scale.

[For production]

In the present invention, when the drag knob is rotated, the rotation of the sun gear that rotates together with the drag knob is transmitted to the planetary gear inscribed in the internal gear, and the planetary gear is caused to revolve around the sun gear while rotating. As a result, the amount of rotation of the drag knob is decelerated, converted into a rotation amount for displaying drag force proportional to the amount of rotation, and the drag force display body is rotated.

Therefore, by looking at the display scale indicated by the indicator as the drag force indicator 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 drag force indicator.

A washer pressing body 16 is fitted into the cylindrical portion 10 so as to be movable in the axial direction. Rotation is prevented by engaging a protrusion 16a protruding from the washer press body 16 and a compression spring 17 for adjusting the drag force is interposed between the washer press body 16 and the second drag washer 14 facing thereto. . Further, a drag adjustment screw body 18 is screwed into the center of the washer pressing body 16, and the head 18a of this screw body 18 can be rotated into a center hole 19a of a partition wall 19 provided on the opening side in the cylindrical portion 10. A front plate 20 of a cylindrical drag knob 20 whose front end surface is closed is attached to the head 18a which is fitted into the head 18a and projects outward from the partition wall 19.
The center boss portion 20c of the drag knob 20 is fixed with a screw 21, and the cylindrical portion 20b of the drag knob 20 is fitted to the outer periphery of the cylindrical portion 10 with a gap therebetween.

In FIGS. 2 to 6, reference numeral 22 denotes a drag display mechanism that is assembled into the opening of the cylindrical portion 10 and displays a drag force proportional to the amount of rotation of the drag knob 2o.

This drag force display mechanism 22 includes a sun gear 23 formed on the outer periphery of the center boss portion 20c of the drag knob 20, and a cylindrical portion 1.
an internal gear 24 formed on the inner circumferential wall of the open end of 0; a plurality of planetary gears 25 that mesh internally with the circular gear 24;
It is composed of a cylindrical drag force display body 26 that rotatably supports these planetary gears 25 at predetermined angular positions, and the cylindrical portion 26a of the drag force display body 26 is connected to the cylindrical portion 20b of the drag knob 20. The cylindrical portion 20 of the drag knob is fitted so as to cover the outer periphery of the cylindrical portion 10.
A scale 27 indicating a drag force proportional to the amount of rotation of the drag knob 20 is formed around the entire circumference of the cylinder part 26a, which is longer than the cylinder part 20b and protrudes outward from the cylinder part 20b.
This display scale 27 is designed to display the drag force corresponding to two to three rotations of the drag knob 20 from the minimum value (drag force is almost zero) to the maximum value within one rotation of the drag force display body 26. It has become. In addition, the cylindrical portion 26
An instruction mark 28 for indicating the display scale 27 is formed on the surface of the reel body 1 facing the edge a.

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

To set the drag force of the drag device 9 when the drag force is almost zero (“0” on the display scale 27 matches the instruction mark 28) to the desired drag force according to the thickness of the fishing line and the target fish, use the drag knob. 20 in the direction of arrow A in FIG. Then, the screw body 18 integrated with the drag knob 20
are also rotated in the same direction, the washer pressing body 16 screwed into the screw body 18 moves in the direction of arrow B in FIG. The pressure increases, and the frictional coupling force between the first and second drag washers 13 and 14 increases. As a result,
The braking force, that is, the drag force applied to the bearing member 12 that is non-rotatably coupled to the spool shaft 7 increases. The amount of rotation of the drag knob 20 at this time is one rotation or more.

On the other hand, as the drag knob 20 is rotated in the direction of arrow A, the sun gear 23 integrated therewith is rotated in the same direction as the drag knob 20, so that it meshes with the sun gear 23 and the internal gear 24.
The planetary gear 25 inscribed in the planetary gear 25 rotates on its own axis in the direction of the arrow C in FIG.

At this time, the rotation of the drag knob 20 is decelerated by the planetary motion of the planetary gear 25 and is transmitted to the drag force indicator 26, so the amount of rotation of the drag force indicator 26 is determined by the number of teeth of the sun gear 23 and the planetary gear 25, Although it varies depending on the diameter of the internal gear 24, the rotation amount is less than a fraction of the amount of rotation of the drag knob 20. That is, the amount of rotation of the drag knob 20 is converted into the amount of rotation for displaying the drag force, which is proportional to the amount of rotation of the drag knob 20.

Therefore, if the arbitrary numerical value of the display scale 27 on the drag force display body 26, which rotates at a reduced speed as the drag knob 20 is rotated, is aligned with the indication mark 28, the scale value indicated by the indication mark 28 will be proportional to the amount of rotation of the drag knob 20. Becomes Dragka. That is, the drag force can be set simply by aligning the display scale 27 of the drag force display body 26, which is rotated at a reduced speed, with the instruction mark 28 on the fixed side.Moreover, in order to adjust the drag force to this setting value, It is no longer necessary to pay attention to the amount of rotation of the drag knob 20 as in the past, and to memorize the amount of rotation. Desired drag force setting and adjustment can be performed easily and quickly.

In addition, the amount of rotation of the drag knob 20 is decelerated, and the display scale 27
Since the drag force indicator 26 can display the drag force according to the amount of rotation of the drag knob within one rotation, just by looking at the display scale 27 indicated by the instruction mark 28, the setting status of the drag force can be changed from the minimum value to the maximum value. Not only can a wide range of settings be obtained, but also when resetting a drag lever that has been set to -degrees, it can be easily done by simply rotating the drag knob 20 so that the setting scale matches the indicator mark 28. can.

Furthermore, since the display scale 27 displays the drag force that is proportional to the amount of rotation of the drag knob 20, it is possible to prevent the drag knob 20 from becoming too loose or too tight due to an error in adjusting the amount of rotation of the knob as in the prior art.

Further, the cylindrical portion 20b of the drag knob 20 is connected to the drag force display body 2.
Since the cylindrical portion 26a of No. 6 is covered from the outer periphery, the rotation of the drag force display body 26 does not interfere with the rotation operation of the drag knob 20.

FIGS. 7 and 8 show a second view of the drag display device of the present invention.
In this example, the first
The difference from the above embodiment is that the drag knob 20 is molded from acrylic or other transparent material, and the length in the axial direction of the cylindrical portion 20b of the drag knob 20 is the same as that of the cylindrical portion 26 of the drag indicator 26.
The length of a is the same as or slightly longer than that so that the entire drag force indicator 26 is accommodated within the drag knob 20, and the opening of the drag indicator 26 covered by the cylindrical portion 20b of the drag knob 20 is Scale 2 for drag force display on the outer periphery of the end
7 was formed.

In such an embodiment, since the outer periphery of the drag force display body 26 including the display scale 27 can be completely covered by the drag knob 20, the display scale 27 is not worn out and its clarity can be maintained. In addition, drag force display body 26
does not protrude from the drag knob 20, so when the drag knob 20 is gripped with the fingers, the fingers do not touch the drag force indicator 26, which has the effect of making it easier to rotate the drag knob 20.

In addition, in FIG. 8, if the drag force display body 26 is molded from a transparent material, an instruction mark or display scale can be formed on the open end surface 29 of the cylindrical portion 1O.

FIG. 9 is a sectional view showing a third embodiment of the drag display device according to the present invention, which enables zero setting.

In this embodiment, the same parts as in FIG. 2 are given the same reference numerals, and the explanation thereof will be omitted, and the parts different from those in FIG. 2 will be mainly described.

That is, the difference from the first embodiment is that the partition wall 1 of the cylindrical portion 10
Head 1 of drag adjustment screw body 18 protruding outward from 9
The protruding length of the drag knob 8a is made longer, and the center boss part 20C of the drag knob 20 is fitted into the head part 18a so as to be rotatable and slidable in the axial direction. A compression spring 30 is interposed between the head of the rod and the center boss 2Oc so that the center boss 20c is always pressed against the rear part 18b of the threaded rod head 18a, and the step 18b and the center pressed against this Boss part 20
Concave and convex portions 31 and 32 that engage with each other are formed on the end faces of c, respectively, and these concave and convex portions 31 and 32 are formed on the end surfaces of the compression springs 30 and 30.
so that it is always engaged.

In the embodiment with the above configuration, when zero setting the drag indicator scale, pull the drag knob 20 in the direction of arrow E in FIG.
In this state, rotate the drag knob 20 to the left or right,
Rotate the drag force display body 26 at a reduced speed until it reaches "0" on the display scale.
” position to the direction mark. This completes the zero setting of the drag force indicator 26. Once zero setting is completed, move arrow E to drag knob 20.
When the tensile force in the direction is released, the drag knob 20 returns to its original position, engages its uneven portions 31 and 32, and the drag knob 2
0 to the screw body 18.

Thereby, by rotating the drag knob 20, the drag force can be adjusted.

Further, 46 is a drag device that applies a drag force to the spool 43, and this drag device 46 includes a brake plate 46a, a spring plate 46b interposed between the brake plate 46a and the front wall 40a of the reel body 40, and a reel body. A rod-shaped pressing body 46c is supported in parallel to the rotating shaft 43 by a threaded portion 46c1 at one end, and is threaded through the front wall 40a of the reel body 40 to press the spring plate 46b against the brake plate 46a. A bearing member 46d supports the other end of 46c in an axially slidable and non-rotating manner and is rotatably supported at the center of the rear end cylindrical portion 47 of the reel body 40, and a screw 48 is attached to this bearing member 46d. and a drag knob 46e (having the same shape as the drag knob 20 in FIG. 2) fixed to the cylindrical portion 47 and inside the drag knob 46c, as in the case of FIG. gear.
