Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a spinning reel drag force measuring device, and more specifically, a spinning reel drag force measuring device that enables actual measurement and confirmation of drag force and that allows easy setting of the appropriate drag force of the fishing line used. This invention relates to a drag force measuring device for a reel.

[Conventional technology]

Spinning reels are generally equipped with a drag device to prevent the line from being cut due to strong pulling by a fish, violent reversal, etc., and this is known from Japanese Utility Model Application Publication No. 48-50592.゛This type of drag device generally has a structure that is connected to the spool shaft.
Then, by rotating the drag knob left and right to adjust the tightening force on the drag washer group, the rotational torque of the spool in the line payout direction, that is, the drag force (fishing line pulling output)
is adjusted according to the strength of the fishing line wound on the spool.

[Problem that the invention seeks to solve]

In the conventional spinning 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 displayed by aligning the indicator on the knob with the display scale. 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 indicate the actual drag force, but only represents the approximate drag force. . Therefore, it is impossible to know how much drag force is actually set, and if the drag washer is worn or the spring force is reduced due to fatigue of the spring member, the scale value indicated by the knob may differ. The relationship with the drag force has changed and it is almost impossible to accurately set the desired drag force. Furthermore, since anglers set the drag force by intuitively sensing the pulling force when pulling out the fishing line wound on the spool, there are variations in the drag force setting by beginners and experts.
There has been a problem in that troubles such as tightening the fishing line to a drag force that exceeds the strength of the fishing line frequently causes the line to break during fishing.

[Purpose of the invention]

The present invention has been made to solve the above-mentioned problems, and provides a spinning reel drag force measuring device that can actually measure and confirm the adjusted drag force and also facilitates drag force settings suitable for the fishing line used. The purpose is to provide.

Means for Solving Problem C] The spinning reel drag measuring device according to the present invention has the following features:
a rotor with a bail rotatably provided on a reel body; a spool rotatably supported by a spool shaft on the reel body so as to be able to reciprocate in the axial direction; and a spool around which a fishing line is wound as the rotor rotates; In a spinning reel having a drag device attached to the main body and frictionally coupled to the spool shaft to apply a drag force to the spool, a measuring operation member for rotationally operating the spool, this operation member and the spool or together with this A measurement spring member is provided to connect the rotating members to each other and generates a rotational torque according to a set drag force of the drag device as the operating member rotates, and the measurement spring member is connected to the measurement spring member. The device is equipped with a display unit that displays the relative rotation amount between the operating member and the spool or a member that rotates together with the spool as a drag force.

[Action of the invention]

In the present invention, by rotating the measurement operation member, a rotational torque corresponding to the elastic deformation of the measurement spring member is generated on the spool braked by the drag device, and this rotational torque is set by the drag device. When a drag force is applied, the spool including the operating member rotates against the drag force, and by indicating on the display the relative displacement between the operating member and the spool or other members rotating together with the operating member. Enables actual measurement of setting drag force.

Further, the display scale member 22 is fixed to the bottom of the front ring-shaped recess 8C of the spool 8, and scales 22a and 22b for displaying the set drag force are formed at two opposing locations on the surface of the display scale member 22. 22a and 22b represent the strength of the fishing line used, for example, in bond. Further, the indicating member 23 is rotatably fitted into the cylindrical portion 8a of the spool 8, is arranged concentrically inside the display scale member 22, and has a protrusion 23a that engages with the operating drum 20.
and a display section 23b that indicates the scales 22a and 22b,
It is equipped with 23c.

In addition, 27 is a name plate inserted into the front of the stopper member 25 for removing the drum, and 28 is a button for removing the spool, which is attached to the center of the stopper member 25 so that it can slide in the axial direction. The portion facing the tip of the spool shaft 6 is formed into a bifurcated shape, and when the push button 28 is pressed in the direction of the arrow in FIG.
The spool 8 can be separated from the spool shaft 6 by expanding the snap shaft locking pieces 10a of the snap ring 10 and removing the snap ring 10 from the spool shaft 6.

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

First, the adjustment knob 17 of the drag device 11 is rotated in accordance with the thickness of the fishing line 7 wound around the spool 8, and the spring 18 is rotated.
Press the washer stack to set the desired drag force.

Next, when the measuring operation drum 20 is grasped with the fingertips and rotated in the six directions (clockwise direction) shown by the solid line arrows in FIG. ), the spool 8 does not rotate, and only the operating drum 20 and instruction member 23 move in the direction of arrow A.
Rotate in the direction. At this time, the torsion spring 21 for measuring drag force is elastically deformed in the winding direction, and the operating drum 20
The rotational torque increases. If the rotational torque due to the elastic deformation of the I-john spring 21 becomes even slightly larger than the drag force set in the drag device 11, a slip occurs between each washer of the drag device 11, and the rotation torque including the spool shaft 6 The entire spool 8 is rotated together with the operating drum 20 in the direction of arrow A. Therefore, if the scales 22a and 22b on the display scale member 22 pointed to by the indicating portions 23b and 23c of the indicating member 23 at this time are read, the values become the actual drag force, and the actual measured value of the drag force can be confirmed.

For example, when the operating drum 20 is rotated from the state shown by the solid line to the state shown by the two-dot chain line in FIG. 2, if the spool 8 is also rotated together in the direction indicated by the arrow, then the scale 6. 1b (bond) is the actual drag force set by the drag device 11, and it can be recognized that a tensile force of 6 pounds acts on the thread withdrawal. Therefore, by knowing the displayed value, the set drag force can be adjusted to spool 8.
It is possible to accurately know whether the fishing line 7 is suitable for the fishing line 7 wound around the fishing line 7. For example, if the fishing line used by an angler is 6.1b line, then 6.1b line is used. It is easy to see that the strength of the fishing line is usable up to the lb indication, and even beginners of fishing can set the appropriate drag force, and this greatly reduces the occurrence of troubles such as line breakage due to inappropriate drag force settings. In addition, even if the washer of the drag device 11 is worn out, it is possible to accurately set the drag force regardless of the scale of the adjustment knob.

Further, by operating the adjustment knob 17 of the drag device 11 while operating the measurement drum 20 in the measurement state, the drag force can be adjusted to match the fishing line 7 used. In addition, operation drum 2
If you release your finger from 0, the operating drum 20 will release the torsion spring 2.
1 returns it to its original position.

FIG. 4 shows another embodiment of the drag indicator display method according to the present invention.

In this embodiment, an instruction section 29 for indicating the scales 22a and 22b of the display scale member 22 is provided on the outer periphery of the measuring operation drum 2o.

In this embodiment, the same effects as those shown in the first embodiment can be obtained, and the indicating member 23 can be omitted.

FIG. 5 shows still another embodiment of the drag force display system according to the present invention, in which a drag force display scale 30 is formed on the outer periphery of the measuring operation drum 20, and a spool 8 is disposed opposite to the drag force display scale 30.
An indicator portion 31a is formed on a ring member 31 (corresponding to the display scale member 22 in FIG. 3) that is inserted into the recess 8C.

In this embodiment as well, the same effects as in the case of FIG. 4 can be obtained.

In this embodiment, the display scale and the indicator are formed using separate members in the recess on the front surface of the spool for display. A separate member may be omitted by displaying (engraving) or the like. Furthermore, it goes without saying that the display means is not limited to this.

6 and 7 show a second embodiment of the drag force measuring device of the present invention, in which a measuring operation drum 20 is attached to the front cylindrical portion 8a of the spool 8 and can be rotated by a retaining member 25 and a screw 24. At the same time, one end of a drag force measuring plate spring 32 extending in the radial direction is fixed to the outer periphery of the cylindrical portion 8a, and the other end is latched to a protrusion 34 protruding from the back surface of the operation drum 20. An instruction section 33 is provided on the outer periphery of the drum 20.
A scale 35 for displaying drag force is formed on the bottom surface of the front recess 8C of the spool 8 in correspondence with the indicator 34, as shown in FIG.

This embodiment also provides the same effects as the first embodiment, and also has the advantage of simplifying the measuring mechanism.

8 and 9 show a third embodiment of the present invention, in which a metal shaft 36 is fixed coaxially to the tip of the spool shaft 6, and the spool 8 is rotated on this metal shaft 36. At the same time, the knob 37 is screwed onto the metal shaft 36 opening on the front surface of the spool 8 to prevent the spool 8 from being removed. The drum 20 is rotatably attached by a removal prevention member 41, and a spiral measuring spring 38 is arranged concentrically between the surfaces facing the spool 8 corresponding to the measuring operation drum 20, and one end thereof is secured to the metal shaft 36, and the other end is secured to the measurement operation drum 20. A drag display scale 39 is formed on the outer periphery of the measuring operation drum 20, and an instruction mark 40 is formed on the outer periphery of the spool 8 facing the drag indicator scale 39.
was formed.

In this embodiment, in addition to obtaining the same effects as the first embodiment, the measuring mechanism is simpler than that of the first embodiment, and an operating drum for measurement is formed at the rear of the spool. This makes it possible to easily measure the drag force while holding the drum in the palm of your hand and gripping the reel.

FIGS. 10 and 11 show a fourth embodiment of the present invention.

In this figure, the same reference numerals as in FIG. 2 indicate the same components, and the difference from FIG. The drag force of the drag device 11 can be measured and displayed by rotating the drag device 11.

For this purpose, in this embodiment, the spool 8 and the operating drum 2 are
The measuring torsion spring 21A having both ends connected to the torsion spring 21A is constituted by a left-handed spring opposite to the torsion spring 21 shown in FIG.

In the drag force measuring device configured as described above, when the drag force adjusted by the drag device 11 is measured (i'ffl), when the operating drum 20 is rotated in the direction of arrow B in FIG. When the spring 21A is elastically deformed in the winding direction and the rotational torque of the operating drum 20 increases, even if it becomes slightly larger than the drag force set in the drag device 11, a slip occurs between the washers of the drag device. The entire spool 8 including the spool shaft 6 is rotated together with the operating drum 20 in the direction of arrow B. For example, when the operating drum 20 is rotated from the position indicated by the solid line in FIG. If it is rotated in the direction of arrow B, the scale 6.1b (bond) indicated by the indicating parts 23b and 23C at this time becomes the actual drag force set by adjusting the knob of the drag device 11. Therefore, It is possible to accurately know whether or not the indicated value is suitable for the fishing line 7 wound around the spool 8.

In addition to obtaining the same effects as in the first embodiment, this embodiment also allows left-handed anglers or when measuring drag fishing with their left hand to operate the measuring device without putting undue strain on their hands. This improves operability.

The display scale indicates the strength of the fishing line used (e.g. 2°lb,
4.1b, ... bond display) and number (No. 2, No. 3,
No. 4,...), it is not limited to the display to set the most suitable drag force that will not cause line breakage, but also the absolute display so that the drag force (fishing line pulling output) can be directly seen on the scale. Of course it's a good thing.

〔Effect of the invention〕

As described above, according to the present invention, a drag force measuring mechanism is assembled to a spool coupled to a drag device, and the operating member of this measuring mechanism is operated to generate a rotation torque corresponding to a set drag force, and this rotation Since the drag force is measured and displayed from the torque, it becomes possible to actually measure and recognize the drag force set by the drag device, and there is an effect that it becomes easy to set the drag force suitable for the fishing line used.
