Description
SPECIFICATION
Dragging force measuring device for spinning reels
BACKGROUND OF THE INVENTION
The present invention relates to a dragging force measuring device for a spinning reel and, more particularly, to a dragging force measuring device for a spinning reel, which can measure and confirm the actual dragging force of the spinning reel and can facilitate the setting of a proper dragging force of a fishing line used.
The spinning reel is generally equipped with a dragging mechanism for preventing the fishing line from being cut by an intense tug on the line, an abrupt turn of the line and so on, as is disclosed in Japanese Utility Model Laid
Open No. 48-50592.
The dragging mechanism of this kind is generally constructed to be coupled to a spool pin so that the revolving torque of the spool in a line letting-off direction, i.e. the dragging force (against the tugging force of the line) may be adjusted in accordance with the strength of the line sound on the spool, by turning a drug knob forward and backward to adjust the fastening force on a group of dragging washers.
The aforementioned dragging mechanism for the spinning reel according to the prior art has its dragging force adjusting knob formed with an indication portion and its spool or reel body formed with an indication scale so that the dragging force may be indicated by causing the indication portion of the knob to point the indication scale. This merely indicates the thrusting force of a spring member upon the grouped dragging washers as the extent of revolution of the knob but not the actual dragging force so that it indicates all but a criterion of the dragging force. As a result, it is impossible to known how strong the dragging force is actually set.Especially when the dragging washers have worn or when the spring member has its force dropped due to its fatigue or the like, the relation between the numerical value of the scale indicated by the knob and the dragging force changes to make it impossible to set a desired dragging force accurately. Still the worse, since the fisherman sets the dragging force by sensorily senses the pulling force the fishing line wound on the spool when pulled, the setting of the dragging force by a beginner and an expert disperses to raise a problem that troubles of having the line cut during the fishing are frequently caused by applying an excessive dragging force to the line.
SUMMARY OF THE INVENTION
The present invention has been conceived so as to solve the above-specified problems and has an object to provide a dragging force measuring device for a spinning reel, which can actually measure and confirm the dragging force adjusted and can facilitate the setting a dragging force suited for the fishing line used.
A first feature of the present invention resides in that the most proper dragging force for fishing conditions can be set reliably and easily.
According to a second feature of the present invention, the dragging force suited for the strength of the line used can be set without fail to prevent a trouble such as the cutting of the line beforehand.
According to a third feature of the present invention, the most proper dragging force for the actual fighting (or letting-off of the line) with the fish can be set by changing the adjustment of the dragging force to a strong or weak level during the fighting, so that the subsequent operation can be made remarkably convenient.
According to a fourth feature of the present invention, the dragging force, i.e., the characteristics of the dragging mechanism can be confirmed by actual measurements so that the wear (or lifetime) of the dragging washers or the like can be properly grasped to make preparations for the repair.
By turning a measuring operation member, according to the operations of the present invention, a revolving torque according to the elastic deformation of a measuring spring member is established in a spool being braked by the dragging mechanism. When the revolving torque reaches a dragging force set by the dragging mechanism, the spool including the operation member is revolved against the dragging force. Then, the set dragging force can be actually measured by indicating in an indication portion the relative displacement between the operation member and the spool or a member made rotatable with the latter.
By turning a measuring operation member, according to the Other operations of the present invention, a revolving torque according to the elastic deformation of a measuring spring member is establihsed in a spool being braked by the dragging mechanism. When the revolving torque reaches a dragging force set by the dragging mechanism, the spool including the operation member is revolved against the dragging force. Then the set dragging force can be actually measured by indicating with a scale and in an indication portion and the relative displacement between the operation member and the spool.

DESCRIPTION OF THE PREFERRED EMBODI
MENTS
Figs. 1 to 3 show the first embodiment of the dragging force measuring device for the spinning reel according to the present invention.
In these drawings, reference numeral 1 indicates a reel body; numberal 2 a rotor which is rotatably borne on the reel body 1 through a not-shown spindle; numeral 3 a bail which is attached to the rotor 2 through an arm lever 4; and numeral 5 a handle which is attached to the reel body 1. The handle 5 and the bearing spindle of the aforementioned rotor 2 are connected through a not-shown gear mechanism which is mounted in the reel body 1 so that the rotor 2 and the bail 3 can be revolved in a line taking-up direction by turning the handle 5. Indicated at numeral 6 is a spool pin which is supported on the reel body 1 coaxially with the bearing spindle of the aforementioned rotor 2 such that it can revolve and reciprocate in the axial directions.
On a radial projection 6a of that spool pin 6 at the side of the rotor 2, there is irrotatably fitted a recess 8d of a spool 8 which is used to wind a fishing line 7 thereon. On the leading end of the spool pin 6 projecting into a cylindrical portion 8a which is concentrically formed at the front face of the spool 8, moreover, there is retained a snap ring 10 for attaching and detaching the spool 8 so that the spool 8 can be removed from the spool pin 6 by removing said snap ring 10. This makes it possible to interchange the fishing line suitable for target fish by interchanging the spool 8, if necessary.
Indicated at numeral 11 is a dragging mechanism which is attached to the rear end of the aforementioned reel body 1. This dragging mechanism 11 is constructed of: a drag shaft 12 which is rotatably borne in the reel body 1 and in which the rear end portion of the aforementioned spool pin 6 is fitted immovably relative thereto but slidably in the axial directions; first dragging washers 14 which are fitted in the drag shaft 14 rotatably relative thereto and engaged irrotatably with a cylindrical portion 13 formed in the reel body 1; second dragging washers 15 which are fitted irrotatably relative to the drag shaft 12 and freed from the cylindrical portion 13; a plurality of lining washers 16 which are sandwiched between those first and second dragging washers 14 and 15; a dragging force adjusting knob 17 which is screwed on the aforementioned cylindrical portion; and a dragging force adjusting coil spring 18 which is interposed between that knob 17 and the laminated assembly of aforementioned respective washers 14, 15 and 16. As a result, the dragging force upon the spool 8 can be adjusted by turning the dragging force adjusting knob 17 forward and backward to change the thrusting force upon the washer group.
Indicated at reference numeral 19 is, on the other hand, a dragging force measuring mechanism which is assembled with the spool 8. This dragging force measuring mechanism 19 is equipped with: an operation drum 20 for measuring the dragging force; a measuring torsion spring 21 for establishing in that operation drum 20 and the spool 8 a torque corresponding to the dragging force set by the dragging mechanism 11; a ring-shaped indicating scale member 22 for indicating the actually measured value of the dragging force set by the dragging mechanism 11; and an indicating member 23 which is made rotatably integrally with the operation drum 20.
This operation drum 20 is rotatably fitted in the cylindrical portion 8a, which concentrically projects from the center of the front face of the spool 8, and is rotatably held by a holding member 25 which is fixed to the cylindrical portion 8a by means of screws 24. On the other hand, the aforementioned measuring torsion spring 21 is fitted in the aforementioned cylindrical portion 8a and has its one end 21a extending through a washer 26 fitted in the cylindrical portion 8a and retained near the center of the spool 8 and its other end portion 21b retained in the operation drum 20 through both a cut-away portion 25a (as shown in Fig. 3) formed in the knob holding member 25 and a cut-away portion (as shown in Fig. 3) formed in the cylindrical portion 8a.
Moreover, the aforementioned indicating scale member 22 is fixed on the bottom of a recess 8c having a ring-shaped front face and is formed scales 22a and 22b for indicating set dragging forces in two opposed portions of its surface. Those scales 22a and 22b indicate the strength of the fishing line used in pounds or the like. On the other hand, the indicating member 23 is rotatably fitted in the cylindrical portion 8a of the aforementioned spool 8 and is concentrically arranged in the indicating scale member 22. Moreover, the indicating member 23 is equipped with a projection 23a to be retained in the aforementioned operation drum 20, and indicating portions 23b and 23b for pointing the aforementioned scales 22a and 22b.
Incidentally, numeral 27 indicates a name plate which is fitted in the front face of the drum holding member 25. Indicated at numeral 28 is a spool removing push button which is fitted in the central portion of the knob holding member 25 slidably in the axial directions and which is bifurcated at its portion facing the leading end of the spool pin 6. When the push button 28 is thrusted in the direction indicated by arrow in Fig. 1, its bifurcated leading end portion 28a expands the spool pin retaining portions 10a of the snap ring 10 to disengage the snap ring 10 from the spool pin 6 so that the spool 8 can be separated from the spool pin 6.
Next, the dragging force measuring operations of the present embodiment having the construction thus far described will be explained in the following.
First of all, the adjusting knob 17 of the dragging mechanism 11 is turned in accordance with the thickness of the fishing line 7 wound on the spool 8 so that a desired dragging force is set by thrusting the washer laminated assembly by the action of the spring 18.
Next, the measuring operation drum 20 is pinched by the finger tips and turned in the direction of solid arrow A of Fig. 2. Then, the spool 8 is left irrotational, but only the operation drum 20 and the indicating member 23 are turned in the direction of the arrow A, because the braking (or dragging) force of the dragging mechanism 11 is applied to the spool 8 through the spool pin 6. At this time, the dragging force measuring torsion spring 21 is elastically deformed in the winding direction so that the revolving torque of the operation drum 20 increases.If the revolving torque accompanying the elastic deformation of the torsion spring 21 slightly exceeds the dragging force set by the dragging mechanism 11, moreover, slippage is caused between the respectively adjacent washers of the dragging mechanism 11 so that the spool 8 containing the spool pin 6 is turned in its entirety integrally with the operation drum 20 in the direction of the arrow A. If the scales 22a and 22b on the indicating scale member 22 pointed at this time by the indicating portions 23b and 23c of the indicating member are read out, therefore, the values indicates the actual dragging force so that the actually measured value of the dragging force can be confirmed.
If the spool 8 is turned integrally with the operation drum 20 in the direction of the arrow A when the drum 20 is turned from the state of solid lines of Fig. 2 to the state of double-dotted lines, for example, the scale 6 lb (i.e., pounds) indicated by the indicating portions 23b and 23c gives the actual dragging force set by the dragging mechanism 11 so that the action of the tensile force of 6 pounds upon the line being let off can be confirmed. By knowing the indicated value, therefore, it is possible to accurately known whether or not the dragging force set is suitable for the fishing line 7 wound on the spool 8. As a result, if the line used by the fisherman is one for 6 lb, it is easily known that the line has a strength allowing him to use it up to the indication of 6 lb.Thus, even the fishing beginner can set a proper dragging force and is drastically freed from troubles of having the line cut due to an improper setting of the dragging force. At the same time, the beginner can accurately set the dragging force independently of the scaling of the adjusting knob even if the washers of the dragging mechanism 11 wear.
If the adjusting knob 17 of the dragging mechanism 11 is operated while the measur ing drum 20 being in its measuring state, on the other hand, the dragging force can be adjusted to a level suited for the fishing line 7 used. Incidentally, the operation drum 20 is caused to restore its initial position by the action of the torsion spring 21 if it is released from the fingers.
Fig. 4 shows another embodiment of the dragging force indicating device according to the present invention.
In this embodiment, the measuring operation drum 20 is formed on its outer circumference with an indicating portion 29 for pointing the scales 22a and 22b of the indicating scale member 22.
According to this embodiment, the indicating member 23 can be dispensed with in addition to effects similar to those of the foregoing first embodiment.
Fig. 5 shows still another embodiment of the dragging force indicating device of the present invention. The measuring operation drum 20 is formed with a dragging force indicating scale 30 whereas a ring member (which corresponds to the indicating scale member 22 of Fig. 3) 31 to be fitted in the recess 8c of the spool 8 in a position to face the indicating scale 30 is formed with indicating portions 31a.
This embodiment can also enjoy effects similar to those of the aforementioned case of
Fig. 4.
In this embodiment, incidentally, the front face recess of the spool is formed by the separate member with the indicating scale and the indicating portions. However, the separate member may be disposed with by forming the indicating scale and the indicating portions directly on the front face recess of the spool by a printing or molding (such as engraving) process. Moreover, it is quite natural that the indicating means should not be limited to the enumerated ones.
Figs. 6 and 7 show a second embodiment of the dragging force measuring device of the present invention, in which the measuring operation drum 20 is rotatably fitted on the cylindrical portion 8a of the front face of the spool 8 by means of the holding member 25 and the screws 24, a dragging force measuring leaf spring 32 extending in the radial directions has its one end fixed to the outer circumference of the cylindrical portion 8a and its other end retained by projections 34 formed to project from the back of the operation drum 20, and in which an indicating portion 33 is formed on the outer circumference of the operation drum 20 whereas a dragging force indicating scale 35 is formed on the bottom of the front face recess 8c of the spool 8 in a manner to correspond to that indicating portion 33, as shown in Fig. 7.
According to this embodiment, there can be attained an effect that the measuring mechanism can be simplified, in addition to effects similar to those of the foregoing first embodiment.
On the other hand, Figs. 8 and 9 show a third embodiment of the present invention, in which a metal spindle 36 is coaxially fixed on the leading end of the spool pin 6, in which the spool 8 is irrotatably fitted on the metal spindle 36, in which a knob 37 is screwed into the metal spindle 36 opened into the front face of the spool 8 thereby to prevent the spool 8 from coming out, in which the measuring operation drum 20 is rotatably fitted on the base of the metal spindle 36 joined to the spool pin 6 by means of a holding member 41, and in which a helical measuring spring 38 is concentrically arranged between the opposed faces of the measuring operation drum 20 and the spool 8 such that its one end retained by the metal spindle 36 and its other end retained by the measuring operation drum 20.Moreover, the measuring operation drum 20 is formed on its outer circumference with a dragging force indicating scale 39 whereas an indication mark 40 is formed on the outer circumference of the spool 8 facing the operation drum 20.
In addition to effects similar to those of the foregoing first embodiment, according to this third embodiment, the measuring mechanism can be made simpler than that of the first embodiment. Since the measuring operation drum is arranged at the back of the spool, moreover, there can be attained another effect that the dragging force can be easily measured without any trouble while the drum being held in the palm and the reel being gripped.
Although quite natural, incidentally, the indicating scale should not be limited to the indication for setting such a dragging force as is the most suitable for the strength (in pounds such as 2 Ib or 4 Ib) or the grade number (e.g., 2nd, 3rd or 4th grade) of the fishing line used without any cut but may be made so absolute as to make the dragging force (upon the line being pulled) directly visible.
As has been described hereinbefore, according to the present invention, the dragging force measuring mechanism is assembled with the spool joined to the dragging mechanism, and the operation member of the measuring mechanism is operated to establish the revolving torque corresponding to the set dragging force thereby to measure and indicate the dragging force in terms of the revolving torque. As a result, there can be attained the effects that the dragging force set by the dragging mechanism can be actually measured and recognized and that the setting of the dragging force suited for the fishing line used can be facilitated.
Figs. 10 and 11 show a fourth embodiment of the dragging force measuring device for a front drag type spinning reel according to the present invention.
In those drawings: reference numeral 51 indicates a reel body; numeral 52 a rotor which is rotatably borne on the reel body 51 through a not-shown spindle; numeral 53 a bail which is attached to the rotor 52 through an arm lever 54; and numeral 55 a handle which is attached to the reel body 51. The handle 55 and the bearing spindle of the aforementioned rotor 52 are connected through a not-shown gear mechanism which is mounted in the reel body 51 so that the rotor 52 and the bail 53 can be revolved in a line taking-up direction by turning the handle 55. Indicated at numeral 56 is a spool pin which is supported on the reel body 51 coaxially with the bearing spindle of the aforementioned rotor 52 such that it can revolve and reciprocate in the axial directions.On the projecting stem 56a of that spool pin 56 toward the rotor 52, there is rotatably borne a spool 57 for winding a fishing line L, into which the projecting stem 56a is inserted at a central bore 57a. The spool 57 has its movement regulated toward the rotor 52 by the action of a receiving portion 56b fixed on the projecting stem 56a. In the spool pin inserting portion of the spool 57, there is fitted a dragging mechanism 58 for applying its dragging force to the spool 57.
The aforementioned dragging mechanism 58 is constructed of: a first dragging washer 59 which is fitted in a cylindrical hole 57b formed in the spool 57 concentrically with the spool pin 56 such that it is joined to the spool 57 irrotatably relative thereto and fitted on the spool pin 56 rotatably relative thereto; a plurality of second dragging washers 60 which sandwich the first dragging washer 59 and are fitted on the spool pin 56 irrotatably relative thereto but in a state to be freed from the spool 57; a plurality of lining washers 61 which are sandwiched between the aforementioned first dragging washer 59 and each of the second dragging washers 60 and between each of the second dragging washers 60 and the bottom of the cylindrical hole 57b; and a receiving washer 62 laminated on the lining washer 61 at the open end side of the front face cylindrical hole 57b.These laminated washer assembly is so held by means of a snap ring 63 engaging with the inner circumference of the opening of the cylindrical hole 57b as to be prevented from coming out. The projection of the spool pin 56 projecting outward from the cylindrical hole 57c is externally threaded at 56c, and a drag adjusting nut 64 is screwed on that externally threaded projection 56c. A drag adjusting knob 65 is splined to the outer circumference of the aforementioned nut 64, which in turn is prevented by a snap ring 66 from coming out of the knob 65. From the knob 65 at the side of the cylindrical hole 57b, moreover, there integrally projects a cylindrical thrusting portion 67 which is in abutment against the receiving washer 62 of the aforementioned laminated washer assembly.A coil spring 68 for adjusting the dragging force is mounted between the stepped portion of the thrusting portion 67 and the nut 64. As a result, if the drag adjusting knob 65 is turned forward or backward, the pressure of the coil spring 68 to be applied to the washer assembly through the thrusting portion 67 is adjusted together with the dragging force upon the spool 57.
On the other hand, reference numeral 69 indicates a dragging force measuring mechanism which is assembled in the front face portion of the spool 57. This dragging force measuring mechanism 69 is equipped with: a measuring operation member 70 having an annular shape; a measuring torsion spring 71 for establishing in the measuring operation member 70 and the spool 57 a torque corresponding to the dragging force set by the dragging mechanism 58; indication scales 72 for indicating the actually measured value of the dragging force set by the dragging mechanism 58; and indicating portions 73 formed on the aforementioned operation member 70.
This measuring operation member 70 is rotatably fitted in a circular recess 74 formed in the front face of the spool 57 concentrially with the spool pin 56 and is so held by a stop ring 75 elastically retained in the inner circumferential wall of the circular recess 74 as to be prevented from coming out. The circular recess 74 is formed in its bottom with an arcuate groove 76 which is positioned concentrically with the spool pin 56 so as to regulate the range of the turning angle of the measuring operation member 70. With that arcuate groove 76, there is engaged a projection 77 which is formed to project from the inner side face of the measuring operation member 70.On the other hand, the aforementioned measuring torsion spring 71 is arranged in a recess 70a, which is formed in the inner side face of the measuring operation member 70, and has its inner circumferential end 71a fixed to the measuring operation member 70 and its inner circumferential end 71b fixed to the spool 57. Moreover, the aforementioned indication scales 72 are formed in two positions in the front face of the edge portion 57c of the spool 57 with a phase difference of 180 degrees in the circumferential direction and are scaled with the strength, e.g., the grade number of the fishing line used. On the other hand, the indicating portions 73 for pointing the aforementioned indication scales 72 are formed on the front face of the outer circumferential edge of the measuring operation member 70.
Next, the dragging force measuring operations of the present embodiment thus constructed will be explained in the following.
First of all, the adjusting knob 65 of the dragging mechanism 58 is turned in accordance with the thickness of the fishing line L wound on the spool 57 so that a desired dragging force is set by thrusting the washer laminated assembly through the thrusting portion 67 by the action of the spring 18.
Next, the knob portion 70b formed on the front face of the measuring operation member 70 is pinched by the finger tips and turned in the direction of solid arrow C of Fig. 11.
Then, the spool 57 is left irrotational at the initial stage, but only the operation member 70 are turned in the direction of the arrow C, because the braking (or dragging) force set by the dragging mechanism 58 is applied to the spool 57. Simultaneously with this, the dragging force measuring torsion spring 71 is elastically deformed in the winding direction so that the revolving torque of the operation member 70 increases. If the revolving torque accompanying the elastic deformation of the torsion spring 71 slightly exceeds the dragging force set by the dragging mechanism 58, moreover, slippage is caused between the first and second dragging washers 59 and 60 through the lining washer 61 of the dragging mechanism 58 so that the spool 57 is turned in its entirety integrally with the operation member 70 in the direction of the arrow C.If the indication scales pointed by the indicating portions 73 at this time are read out, therefore, the values indicates the actual dragging force so that the actually measured value of the dragging force can be confirmed.
If the spool 57 is turned integrally with the operation member 70 in the direction of the arrow C when the operation member 70 is turned from the state of solid lines of Fig. 11 to the state of double-dotted lines, for example, the scale 3 (in the grade number) indicated by the indicating portions 73 gives the actual dragging force set by the dragging mechanism 58 so that the action of the tensile force of the 3rd grade upon the line being let off can be confirmed. By knowing the indicated value, thus, it is possible to accurately know whether or not the dragging force set is suitable for the fishing line wound on the spool 57. As a result, it is easily known that the line being used by the fisherman has the 3rd grade.Thus, even the fishing beginner can set a proper dragging force and is drastically freed from troubles of having the line cut due to an improper setting of the dragging force.
At the same time, the beginner can accurately set the dragging force independently of the scaling of the adjusting knob even if the washers of the dragging mechanism 58 wear.
If the adjusting knob 65 of the dragging mechanism 58 is operated while the measuring member 70 being in its measuring state, on the other hand, the dragging force can be adjusted to a level suited for the fishing line used. Incidentally, the operation member 70 is caused to restore its initial position by the action of the torsion spring 9721 if it is released from the fingers.
Figs. 12 to 14 show a fifth embodiment of the dragging force measuring mechanism according to the present invention.
In Figs 12 to 14, the same reference numerals as those appearing in Figs. 10 and 11 indicate the same portions or parts. The dragging force measuring mechanism 69 in this embodiment is equipped with a drumshaped measuring operation member 70A which is rotatably coaxially fitted in a skirted portion 57d of the spool 57. That measuring operation member 70A is rotatably borne on the bottom of the skirted portion 57d of the spool 57 by means of screws 79 which extend through arcuate slots 78 formed in a bottom plate 70Aa at the fitted side thereof.
On the other hand, a measuring torsion spring 71A is arranged in a circular recess 70Ab, which is formed in the operation member bottom plate 70Aa at the side facing the bottom of the skirted portion 57d of the spool 57, and has its outer circumferential end 71 Aa and its inner circumferential end 71Ab fixed in the operation member 70A and the spool 57, respectively. Moreover, an indication scale 72A is formed, as shown in Fig. 12, on the outer circumference of the skirted portion 57d, whereas an indicating portion 73A is formed on the outer circumference of the measuring operation member 70A in a position to face the indication scale 72A.
In the present embodiment, in case the dragging force is to be measured, the drumshaped operation member 70A is turned in the direction of arrow D of Fig. 14 so that a revolving torque may be established as a result of the deformation of the torsion spring 71A. When the revolving torque accompanying the elastic deformation of the torsion spring 71A exceeds the dragging force set by the dragging mechanism 58, moreover, the spool 57 is turned in its entirety integrally with the operation member 70A in the direction of the arrow D. As a result, if the indication scale 72A pointed by the indicating portion 73A at this time is read out, the actual dragging force can be measured. According to the present embodiment, it is quite natural that effects similar to those of the foregoing fourth embodiment can also be attained.
Figs. 15 and 16 show a sixth embodiment of the dragging measuring mechanism according to the present invention.
In Figs. 15 and 16, the same reference numerals as those appearing in Figs. 10 and 11 indicate the same portions or parts. The dragging force measuring mechanism 69 of this embodiment is equipped with a boss 81 which is rotatably borne on a cylindrical spindle 80 formed to project from the bottom of the spool 57 at the side of the skirted portion 57d. That boss 81 is formed on its outer circumference with a pair of arms 82 and 82 which are arranged with a phase difference of 180 degrees in the circumferential direction.
On the outer circumference of the skirted por tion 57d facing those arms 82 and 82, there are arranged measuring operation members 708 and 70B which are made of arcuate components. From the centers of the inner circumference of those measuring operation members 70B and 70B, there project connecting portions 70Ba and 70Ba which are integrally fixed to the leading ends of the aforementioned arms 82 and 82 through revolving angle range regulating slots 83 and 83 formed in the outer circumferential wall of the skirted portion 57d. Between one arm 82 and the spool 57, moreover, there is interposed a coil spring 71B for establishing a measuring torque.On the other hand, the aforementioned measuring operation members 70B and 70B are formed with indicating portions 73B on their outer circumferences, whereas the skirted portion 57d is formed in its outer circumference with indication scales 728 in positions to face the indicating portion 73B.
When the dragging force is to be measured, according to the sixth embodiment thus constructed, the operation members 70B are turned in the direction of arrow E of Fig. 16 so that a revolving torque may be established as a result of deformation of the coil spring 71B. When the revolving torque accompanying the elastic deformation of the coil spring 71 B exceeds the dragging force set by the dragging mechanism 58, moreover, the spool 57 is turned as a whole integrally with the operation members 70B in the direction of the arrow E. As a result, if the indication scales 72B pointed by the indicating portions 73B at this time are read out, the actual dragging force can be measured.
According to this embodiment, effects similar to those of the foregoing fourth embodiment can be attained.
In the foregoing fifth and sixth embodiments, incidentally, the operation members are formed with the indicating portions whereas the spool is formed with the indication scales, but vice versa, i.e., the operation members may be formed with the indication scales whereas the spool may be formed with the
indicating portions. Moreover, the indicating
scale should not be limited to the indication for setting such a dragging force as is the
most suitable for the grade number (e.g., 2nd,
3rd or 4th grade) or the strength (in pounds
such as 2 lb or 4 lb) of the fishing line used
without any cut but may be made so absolute as to make the dragging force (upon the line
being pulled) directly visible.
As has been described hereinbefore, accord
ing to the present invention, the dragging force measuring mechanism is assembled with the spool having the dragging mechanism as
sembled therein, and the operation member of the measuring mechanism is operated to
establish the revolving torque corresponding to the set dragging force thereby to measure
and indicate the dragging force in terms of the revolving torque. As a result, there can be attained the effects that the dragging force set by the dragging mechanism can be actually measured and recognized and that the setting of the dragging force suited for the fishing line used can be facilitated.
Figs. 17 and 18 show a seventh embodiment of the present invention, in which like reference numerals as those in Fig. 2 designate similar parts. The embodiment of Figs.
17 and 18 has a construction similar to the embodiment of Fig. 2 and different therefrom only in that the dragging force of the dragging mechanism 11 can be measured and indicated by rotating counterclockwise (in the direction of an arrow B), i.e. in the reverse direction to that in the embodiment of Fig. 2.
For this purpose, in this embodiment, the measuring torsion spring 21 A connected at opposite ends to the spool 8 and the operation drum 20 is composed of a snistral coil spring which is coiled in a direction opposite to that of the torsion spring 21 of Fig. 3.
In measuring and confirming the dragging force regulated by the dragging mechanism 11 in the dragging force measuring device thus constructed, if the operation drum 20 is rotated in the direction of an arrow F in Fig. 17, the torsion spring 21 A is resiliently deformed in the direction of coiling up so as to increase the torque of the operation drum 20. As a result, when this torque become even a little bit greater than the dragging force predetermined by the dragging mechanism 11, slip between the washers of the dragging mechanism so that the entire spool 8 including the spool shaft 6 is rotated, in the direction of the arrow B, together with the operation drum 20 as a unit.For instance, if the spool 8 is rotated with the drum 20 downwardly as the operation drum 20 is rotated from the solid line position to the dash-and-two-dot line position in Fig. 17, a graduation or scale mark "6" lb (pound) pointed by the pointers 23b, 23a indicates the actual dragging force that is determined by adjusting the knob of the dragging mechanism 11. Accordingly, it is possible to precisely confirm whether this pointed value is the dragging force suited for the fishing line 7 wound around the spool 8.
This embodiment not only offers the same result as the first embodiment, but is additionally advantageous in that the measuring device can be operated by the (left-handed) fisherman's left hand without charging no burden to the hand.
Figs. 19 and 20 show an eight embodiment of the present invention, in which like reference numerals as those in Fig. 10 designate similar parts. The embodiment of Figs. 17 and
18 has a construction similar to the embodiment of Fig. 10 and different therefrom in the following points.
According to this embodiment, the dragging force measuring operation can take place by the fisherman's left hand without charging no burden to the hand, like the embodiment of
Fig. 10, and the dragging force adjusting operation can take place with ease, unlike the embodiment of Fig. 10. For this purpose, in this embodiment, an outwardly projecting cylindrical boss 94 is formed at the center of a recess 27 in the front surface of the spool 57 concentrically thereof. A doughnut-shaped measuring operation member 70C is rotatably mounted on a periphery of the boss 94 and is prevented by means of a snap ring 95 from being removed from the boss 94.Further, a sinistral torsion spring 96 is mounted concentrically around the periphery of the boss 94 which is disposed inwardly of the measuring operation member 70C, and is connected at one end to the spool 57 and at the other end to the measuring operation member 70C.
Moreover, a dragging force adjusting knob 67 of the dragging mechanism 58 includes a cylindrical tube 65a rotatably mounted in the cylindrical boss 94. The cylindrical tube 65a has, at one end inserted in the boss 94, a pressure portion 67 disposed against a receptor washer 62 of a set of laminated washers.
The cylindrical tube 65a has, at the other end projecting from the boss 74, a grip 65b integral with the tube 65a. Thus the grip 65b projects outwardly from the surface of the measuring operation member 70C so that the adjusting knob 65 can be gripped by the finger, thus facilitating the dragging force adjusting operation. Like the embodiment of Fig. 10, a dragging force adjusting nut 64 and a dragging force adjusting compression spring 68 are mounted in the cylindrical tube 65a of the adjusting knob 65.
In measuring and confirming the dragging force regulated by the dragging mechanism 58 in the dragging force measuring device thus constructed, if the measuring operation member 70C is rotated counterclockwise, i.e. in the direction of in arrow G in Fig. 20, the sinistral torsion spring 96 is resiliently deformed in the direction of coiling up so as to increase the torque of the measuring operation member 70C. As a result, when this torque become even a little bit greater than the dragging force determined by the dragging mechanism 61, slip occurs between the washers of the dragging mechanism via a lining washer so that the entire spool 57 including the spool shaft 56 is rotated, in the direction of the arrow B together with the measuring operation as a unit.For instance, if the spool 57 is started rotating in the direction of the arrow G when the measuring operation member 70C is rotated from the solid line position to the dash-and-two-dot line position in Fig. 20, the value "2" of a graduation or scale mark 72 pointed by the pointer 73 indicates the actual dragging force that is determined by adjusting the knob of the dragging mechanism 61. Accordingly, it is possible to precisely confirm whether this pointed value "2" is the dragging force suited for the fishing line L wound around the spool 57. Assuming that the value "2" is the dragging force which is talorable to a pulling force of 4 Ib (pound), it is possible to confirm that the dragging force is set to a value suitable to a shing line L of 4 Ib.
This embodiment not only offers the same result as the eighth embodiment, but it is additionally advantageous in that the dragging force measuring mechanism can be operated by the (left-handed) fisherman's left hand without charging no burden to the hand. Further, becasse the adjusting knob 65 of the dragging mechanism 58 projects outwardly from the measuring operation member 70C, it is possible to adjust the dragging force reliably with ease.
Although the sinistral torsion spring is used in the foregoing embodiments, it should of course noted that a dextral torsion spring may be used.
Fig. 21 shows a ninth embodiment of the present invention in which the dragging measuring method corresponding to the fourth embodiment.
In Fig. 21, like reference numerals as those in Fig. 19 designate similar parts. This embodiment of Fig. 21 has a construction similar to the embodiment of Fig. 19 and different therefrom in that the spool 57 including the dragging mechanism 58 and the dragging measuring mechanism 69 can be detachably mounted on the spool shaft 56 in a simple cation.
For this purpose, a sleeve 97 is inserted through the axis of the spool 57 and is fixedly secured thereto. A projected portion 56a of the spool shaft 56 is detachably inserted in an axial hole 97a of the sleeve 97. At a distal end of the projected shaft portion 56a a spring member 98 is mounted for preventing the sleeve 97 from being removal. Further, a push putton 99 is axially slidably received in a cylindrical hole 97b formed in a distal end of the sleeve 97 for reducing the diameter of the spring member 98 to thereby allow the spool 57 to be removed. The push button 99 is normally urged, by a coil spring 100 mounted in the cylindrical hole 97b, to project outwardly from the cylindrical hole 97b.
Accordingly, for removing the spool shaft 56 from the spool 57, the push button 99 is depressed in the direction of an arrow H in
Fig. 21 against the bias of the spring 100 to thereby reduce the diameter of the spring member 98 smaller than than the diameter of the axial hole 97a. In this state if the spool 57 is pulled in the direction of an arrow I, the entire spool 57 including the sleeve 97 can be removed from the spool shaft 56.
