Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a device for measuring drag force of a fishing reel, and more specifically, a device for measuring and displaying the actual drag force set in a drag device with a simple operation. The present invention relates to a drag force measuring device for a fishing reel.

[Conventional technology]

Double-bearing reels, spinning reels, closed-face reels, and other fishing reels are subject to a pulling force that exceeds the fishing line's ability due to the strong pull of the fish or sudden reversal, such as when fighting with a hooked fish. A drag device is installed to prevent the fishing line from being easily cut even if the fishing line is acted on, and is known from Japanese Utility Model Application No. 48-50592.

This type of drag device generally includes a drag washer, a lining washer, a compression spring, and a drag assembly so that when the reel is set to fighting mode, the spool, which is about to rotate in the line payout direction in response to the pull of a fish, can be frictionally braked with a predetermined force. It has a structure that combines adjustment knobs, etc.
The drag force, which determines the tensile strength of the spool for drawing out the line, can be adjusted according to the line used and the target fish by adjusting the tightening force against the group of washers using the drag adjustment knob. There is.

[Problem that the invention seeks to solve]

In the conventional fishing reel drag device as described above, an indicator is formed on the drag adjustment knob and a display scale is formed on the spool or reel body, and the drag force is adjusted by aligning the indicator on the knob with the display scale. is now displayed. However, this simply displays the pressing force of the spring member against the drag washer group as the amount of rotation of the knob, and does not display the actual drag force, but only represents the approximate drag force. It is not possible to know how much drag force is acting on the spool, especially if the drag washer is worn or the spring force is reduced due to fatigue of the spring member. It is almost impossible to set the desired drag force accurately.

In addition, when setting the drag force, there is a method that intuitively senses the pulling strength when the fishing line wound on the spool is pulled out by hand, but due to individual differences, the set drag force may vary. As a result, beginners often tighten the fishing line with a drag force that is stronger than the fishing line, resulting in frequent troubles such as the line breaking at the target.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and makes it possible to measure and confirm the actual drag force applied to the spool by the drag device, and also to check the drag force that matches the yarn used and the conditions. It is an object of the present invention to provide a drag force measuring device for a fishing reel that can be easily set.

[Means for solving problems]

According to the present invention. The drag force measuring device for a fishing reel operates so that a fishing line is wound around the spool in a fishing reel equipped with a drag device that applies a drag force to a spool rotatably supported on a reel frame body. A drag force measuring knob that coincides with the rotational axis of the handle is rotatably provided at the mounting base of the handle, and a measuring spring member that generates a rotational torque corresponding to the drag force of the drag device is attached to this measuring knob. At the same time, a scale display section is provided which converts and displays the amount of rotational operation of the measuring knob into drag force.

[Action of the invention]

In the present invention, when the measurement knob is rotated against the measurement spring member, a rotational torque corresponding to the drag force set by the drag device is generated in the measurement knob, and this rotational torque is generated by the drag device. When the drag force exceeds the set value, the drag device slips and the spool begins to rotate. Therefore, by converting and displaying the amount of relative rotational deviation between the knob and the handle at this time on the display section, it becomes possible to measure the actual set drag force of the drag device.

One end of the spool shaft 10 is rotatably supported on the left side plate 5 by a bearing (not shown), and the other end is rotatably supported on the set plate 7 by a bearing 11.

Further, a pinion gear 12 is attached to the protruding shaft portion 10a of the spool shaft 10 that passes through the set plate 7 and protrudes into the right side plate 6 so as to be relatively rotatable and slidable in the axial direction. One end of the pinion gear 12 is configured to be able to engage and disengage a clutch 13 provided on the spool shaft 10, and engagement and disengagement between the pinion gear 12 and the clutch 13 is performed by an operation plate 14. The tip of the protruding shaft portion 10a is engaged with a cast control mechanism 15 provided on the right side plate 6.

A fixed shaft 16 has one end fixed to the set plate 7 and the other end protrudes outward through the right side plate 6. A hollow drive shaft 17 is rotatably fitted into the fixed shaft 16. is,
A handle 18 is fixed to the outwardly projecting end of the drive shaft 17 by a cap nut 19 and a spring member 20, while being held in place by a retaining ring. Further, a drive gear 21 that meshes with the pinion gear 12 is attached to the drive shaft 17 so as to be relatively rotatable, and the drive gear 21 and the drive shaft 17 are frictionally connected by a drag device 22.

The drag device 22 includes a drive shaft 17 as shown in FIG.
A first drag washer 23 is rotatable relative to the drive gear 21 and is not rotatable relative to the drive shaft 17, and a second drag washer 23 is rotatable relative to the drive shaft 17 and rotatable relative to the drive gear 21. The washer 24, the lining washer 25 interposed between the drag washers 23 and 24 and the drive gear 21, the drag force adjustment knob 26 screwed onto the drive shaft 17, and the knob 26 and the drag washer 2

Reference numeral 29 denotes a windmill for preventing the spool from reversing, which is fixed to the drive shaft 17, and a claw member (not shown) can be manually engaged with and disengaged from the windmill.

Further, in FIG. 1, reference numeral 30 is a drag force measuring mechanism for measuring the drag force applied by the drag device 22, and this drag force measuring device 30 is located at the center of the head of the handle attachment cap nut 19. A drag force measuring knob 32 is rotatably fitted into the protruding cylindrical portion 19a and is held in place by a retaining ring 31;
The measuring torsion spring 33 generates a torque corresponding to the drag force applied by the drag device 22, and both ends of the torsion spring 33 are connected to the cap nut 19 and the knob 32, respectively. Further, as shown in FIG. 2, a display scale 34 is formed on the surface of the hexagonal flange 19b of the cap nut 19 to display the measured value of the drag applied by the drag device 22. An indicator portion 35 for indicating the display scale 34 is formed on the outer peripheral surface of the indicator 32 .

It should be noted that when the knob 32 is in a non-operated state, the indicating portion 35 is automatically returned and positioned by the torsion spring 33 to the position indicating the "0" value on the display scale 34.

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

First, rotate the joint knob 26 of the drag device 22,
The thickness of the fishing line 9 wound on the spool.

Adjust so that dragfish can be obtained according to fishing conditions, etc.

At this time, the leaf spring 28
The spring pressure changes, and the entire washer lamination group is pressurized according to this spring pressure, and the drive gear 21 and the drive shaft 17 are frictionally coupled by the friction force corresponding to the pressurizing force, and the spool 8 is Adds numerically unknown drag force.

Next, when the drag setting of the drag device 22 is completed, press the thumb of one hand against the spool 8 to prevent it from rotating as shown in FIG. 32 and rotate it in the direction of arrow A in FIG. Along with this, torsion spring 3 for drag measurement
3 is elastically deformed in the winding direction, and the rotational torque applied to the knob 32 gradually increases.The rotational torque generated according to the amount of elastic deformation of the torsion spring 33 is caused by the drag force applied by the drag device 22. If even slightly increases, the drag washer of the drag device 22 will begin to slip, causing the handle 18. The portion including the drive shaft 17 is rotated together with the knob 32 in the direction of the arrow. Therefore, if you read the scale on the display scale 34 indicated by the indicator 35 when the handle 18 rotates with the knob 32,
The value becomes the actual drag force set by the drag device 22.

FIG. 3 shows the thread pulling force that can pull out the spool from the spool 8 against the drag force on the horizontal axis, and when the handle 18 is rotated in the winding direction with the spool fixed on the vertical axis.
The graph shows the operating force (knob operating force) applied to the handle at the time when the drag washer slips, and the relationship between the two is determined from actual measurements.As is clear from this figure, the relationship between the two is proportional. From now on, the drag force can be accurately measured and displayed from the amount of rotational operation of the knob 32.

Therefore, if you look at the scale value on the scale 34 indicated by the indicator 35 of the knob 32, you can see that the set drag force is on the spool 8.
It is possible to accurately know whether or not the fishing line 9 wound around the fishing line 9 is suitable for the fishing conditions. For example, if the fishing line used by an angler is a 6-bond line, the drag force joint knob 26 can be adjusted so that the drag force is set on the scale of the numerical value r2J. It is possible to set the drag force, which prevents troubles such as thread breakage due to impermeable drag settings.Also, since the characteristics of the drag device 22 can be confirmed by actual measurement, the wear status (lifespan) of the drag washer etc. can be accurately determined. In addition to being able to understand this, maintenance and management of the drag device becomes easy, and the reliability of the reel can be improved.

FIG. 4 shows a modification of the first embodiment.

This embodiment differs from the above first embodiment in the following points:

Of course, even in this modification, the same effects as in the first embodiment can be obtained.

In addition, in the embodiments shown in FIGS. 1 and 4, the handle 1
Since the drag force measuring mechanism is assembled to 8, the drag force measurement operation becomes simple and the structure thereof becomes simple.

In the same figure, reference numeral 40 denotes a reel frame main body having a mounting leg 41 at the bottom, one end of a hollow fixed shaft 42 is fixed to the center of the front part by a screw connection, and a rotary shaft 43 is provided in the hollow part of the fixed shaft 42. is rotatably and penetratingly supported so as to be able to reciprocate in the axial direction, and a spool 45 is rotatably fitted and supported on a retaining plate 44 fitted on the outer periphery of the fixed shaft 42 .

Further, a rotor 46 for winding the fishing line 9 around the spool 45 is fixed to the front end protrusion of the rotary shaft 43, and a pinion gear 47 is fixed to the rear protrusion of the rotary shaft 43 so as to be unable to rotate relative to the shaft. It is attached so that it can slide in any direction. 48 is a spring for constantly urging the rotating shaft 43 backward; 49 is a handle shaft provided on the reel frame body 40 in a direction perpendicular to the rearward protruding shaft portion of the rotating shaft 43;
The handle shaft 49 is rotatably supported by the reel frame main body 40, and a drive gear 50 that meshes with the pinion gear 47 is attached to the handle shaft 49. Furthermore, a handle 51 is screwed onto the outwardly projecting end of the handle shaft 49. 52
It is fixed by.

Further, 53 is a drag device that applies a drag force to the spool 45, and this drag device 53 includes a brake plate 53a interposed between the spool 45 and the spool holding plate 44, and a brake plate 53a interposed between the spool 45 and the spool holding plate 44.

Reference numeral 54 denotes a drag force measuring mechanism assembled to the handle 51, and the drag force measuring mechanism 54 includes a drag force measuring knob 55 and a drag force that generates rotational torque on the knob corresponding to the drag force set by the drag device 53. The knob 55 is provided with a force measuring torsion spring 56, and is rotatably fitted to the outer periphery of a cylindrical portion 57 formed at the mounting base of the handle 51, and is held by a snap ring 58 to prevent it from coming off. Further, the torsion spring 56 is arranged concentrically around the outer periphery of the cylindrical portion 57, and both ends thereof are connected to the handle 51.
and is fixed to the knob 55.

59 is a drag display scale formed on the mounting base surface of the handle 51, and 60 is a scale indicator formed on the same surface of the knob 55.

A front cover 61 is attached to the front of the reel frame body 40 so as to cover the spool 45 and rotor 46, and the thread 9 is pulled out from the front opening 61a of the front cover. Reference numeral 62 denotes a bush lever rotatably attached to the rear of the reel frame main body 40. When the bush lever 62 is pushed in the direction of arrow B, its rotating tip 62a engages with the end of the rearwardly protruding shaft portion of the rotating shaft 43. The rotating shaft 43 is advanced by pressing the rotor 46 against the inner surface of the cover 61 to suppress the fishing line 9, and at the same time the rotor 46 is stopped. Also, when the pressing force on the bushing lever 62 is removed, the rotor 46 becomes free. ing.

In the masked fishing reel configured as described above,
When measuring the drag force of the drag device 53 applied to the spool 45, the fishing line 9 pulled out from the opening 61a of the cover 61 is pressed against the outer peripheral surface of the cover 59 with the thumb of the hand as shown in FIG. A pickup pin (not shown) is engaged to hold the rotor 46 so that it cannot rotate.

In this state, the measuring knob 55 is rotated in the winding direction of the torsion spring 56 as shown by arrow C in FIG. As a result, the torque generated in the knob 55 is transferred to the drag device 53.
When the drag force exceeds the set value in The braked spool 45 begins to rotate against its wear resistance, and the handle 51 also begins to rotate in the same direction as the knob 55. Therefore, when the knob 55 starts to be rotated, the indicator 60 of the knob 55 points to the display scale 59.
By reading the upper scale value, that value can be displayed as the actual drag force set by the drag device 53.

That is, even in the masked type fishing reel, it is possible to actually measure and display the drag force in the same manner as in the above-mentioned double bearing type fishing reel.

It goes without saying that the drag force measuring device of the present invention can be applied not only to the fishing reel described above but also to other spinning reels and the like.

〔Effect of the invention〕

As described above, according to the present invention, a drag force measuring knob is rotatably attached to the mounting base of the fishing line winding handle to the drive shaft, and this knob is connected between the handle bases by a spring member for measuring rotation. However, since the drag force set on the drag device is converted and displayed on the display scale from the rotational torque generated by rotating the knob, the actual drag force set on the drag device can be accurately calculated. Not only can you know this, but you can also easily set the drag hook that matches the line used and fishing conditions. Further, since the drag force measuring mechanism is assembled to the handle, the measuring operation is simple and the structure can be simplified.
