SPOOL SUPPORTING STRUCTURE OF SPINNING REEL
BACKGROUND OF THE INVENTION
1. Field of the Invention This invention relates to a spinning reel for fishing and, more particularly, to an improvement in a spool supporting structure in a spinning reel.
2. Description of the Related Art Fig. 18 shows a spool section o~ a conventional spinning reel. A spool 102 on which a fishing line is wound is rotatably supported on a main shaft 101 as a shaft center. The spool 102 in which the main shaft 101 is inserted has a recessed holding bore 104 around the front shaft center portion of the spool 102; inside the holding bore 104 are assembled a multitude of drag washers 106 in a laminated manner. In the open end of the holding bore 104 an approximately C-shaped retainer 105 is elastically fitted to prevent accidental removal of the drag washers 106.
On the forward end of the main shaft 101 is engagedly mounted a drag knob 103, the end face of which is inserted into the opening section of the holding bore 104 to press a cluster of the drag washers 106 with a predetermined pressure. The amount of compression of the drag washers 106 is increased or decreased by turning this drag knob, thereby adjusting the amount of reversion resistance of the spool 102.
In the conventional spinning reel of the above constitution, the drag washers 106, being worn with frequent use, will require replacement after a predetermined period of time.
When the drag washers 106 of the above-described spinning reel are replaced, it is necessary to replace the cluster of the drag washers 106 by removing the drag knob 103 from the forward end of the main shaft 101, and then by removing the retainer 105 which is elastically fitted in the opening section of the holding bore 104 of the spool 101. This work, however, is very troublesome because it needs the use of a special tool to remove the retainer 105 carefully.
Furthermore, when replacement of the spool 102 is required in order to change the line, the drag knob 103 must be removed; therefore when spool replacement is to be done at a rocky place or at a fishing spot surrounded with water, the drag knob 103 thus removed will be clumsily handled to be lost.
SUMMARY OF THE lNV~N'l'ION
It is an object of the present invention to provide a structure which facilitates drag washer replacement in the conventional spinning reel stated above, and also spool replacement without removing the drag knob.
It is another object of the present invention to provide a structure which allows spool replacement while maintaining a preset drag pressure.
It is further another object of the present invention to provide a structure that enables spool replacement with only one control.
Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter one embodiment of a spool supporting structure of a spinning reel according to the present invention will be explained with reference to the accompanying drawings.
Figs. 1 to 3 show one embodiment of the present invention, wherein a reference numeral 1 denotes a spool shaft of a known structure, which is stroked backward and forward by turning an unillustrated handle.
On the outer periphery of the spool shaft 1 a stationary drag body 2 is fitted.
The stationary drag body 2 is made of a stainless steel or other metal or of a plastic material, and is composed of a cylindrical fitting section 20 which is fitted on the outer periphery of the main shaft 1, and a 21 78~76 disk-shaped resistance plate 21 provided in a collar form on the outer peripheral surface of the rear end of the fitting section 20. The stationary drag body 2 is of such a constitution that a pin 10 is inserted into the fitting section 20 and the main shaft 1 so that the stationary drag body 2 and the main shaft 1 will rotate as one body. On the outer periphery of the fitting section 20 of the stationary drag body 2 a rotary drag body 3 is rotatably mounted. The rotary drag body 3, like the stationary drag body 2, is formed of a metal such as stainless steel or a plastic material, comprising a fitting section 30 fitted on the outer periphery of the fitting section 20 of the stationary drag body 2 and a disk-shaped resistance plate 31 mounted in a form of collar on the outer peripheral surface of the rear end of the fitting section 30. On the inner periphery of the fitting section 31 a brass sleeve 32 is fitted integrally and rotatable with respect to the outer peripheral surface of the fitting section 21 of the stationary drag body 2.
Both the resistance plates 21 and 32 of the stationary drag body 2 and the rotary drag body 3 which are mutually fitted as described above face to each other as shown in Fig. l; between these resistance plates 21 and 32 a drag washer 4 is inserted.
The drag washer 4 is a ring-type (doughnut-type) plate washer produced of cork or carbon fiber, and is fitted in a recess section 22 formed in the mating surface of the resistance plate 21 on the stationary side and held in this state between the resistance plates 21 and 32.
A spool 5 is engagedly fitted and firmly tightened on the outer peripheral surface of the fitting section 30 of the rotary drag body 3.
The spool 5 is a cylindrical body fitted to cover the outer periphery of the rotary drag body 3, and has a through hole 50 along the axial center section.
The spool 5 is provided with an internal thread section 51 in the inner periphery which is the smallest inside diameter section of the through hole 50. This internal thread section 51 is engaged with an external thread section 33 formed in the outer peripheral surface of the fitting section 30 of the rotary drag body 3.
Further, the spool 5 is so constituted that as the internal thread section 51 is tightened further, the rear end face 52 of the internal thread section 51 comes into contact with the front face of the resistance plate 31 of the rotary drag body 3, thereby locking the rotary drag body 3.
The internal thread section 51 of the spool 5 has a larger inside diameter than the outside diameter of a drag knob 6.
On the forward end portion of the spool shaft 1 the drag knob 6 is engagedly mounted.
The drag knob 6 formed substantially cylindrical is produced of aluminum or synthetic resin; in a screw hole 61 formed in the shaft center of one end face, the forward end of the main shaft 1 is engaged, so that the spool can be moved for adjustment in the axial direction of the main shaft 1 by turning the drag knob 6 in both the normal and reverse directions.
The outside diameter of the drab knob 6 formed substantially cylindrical is made somewhat smaller than the inside diameter of the internal thread section 51 which is the smallest inside diameter of the spool 5.
Thus there exists no interference between the inner peripheral surface of the spool 5 and the outer peripheral surface of the drag knob 6, thereby allowing the removal and mounting of the spool 5 in relation to the fitting section-30 of the rotary drag body 3 without removing the drag knob 6 from the forward end of the main shaft 1.
Also, around the screw hole 61 in one end face of the drag knob 6 is formed a circular deep groove 62, in which a drag spring 7 is inserted.
The drag spring 7 is an elastic body of a coil spring produced of a relatively thick wire, for pressing the resistance plate 30 of the rotary drag body 3 against the resistance plate 20 of the stationary drag body 2. The drag spring 7 is elastically fitted in a compressed state between the deep groove 62 of the drag knob 6 and the end face of the fitting section 30 of the rotary drag body 3. It should be noticed that the elastic body for pressing the resistance plate 20 is not limited to the above-mentioned drag spring 7 formed in the shape of coil spring and may be any form that can variably adjust the pressure of the resistance plate 20 by moving the drag knob 6.
As described above, a metal washer 23 and a ring-shaped locking plate 8 of Teflon resin are fitted on the outer periphery of the forward end portion of the fitting section 20 of the stationary drag body 2 with which the end of the drag spring 7 is in contact.
2~ 7~3976 The locking plate 8 has an approximately oval inner bore, and a narrow part of the inner bore is fitted in a slot formed oppositely to the outer peripheral surface of the fitting section 20, thereby locking in relation to the stationary drag body 2.
The locking plate 8 is loosely fitted in a groove 34 provided in the inner periphery of the opening section on the forward end side of the fitting section 30 of the rotary drag body 3, and a set ring 9 is elastically fitted in the groove 34 to thereby develop locking action in the axial direction.
At the front of the spool 5 is provided a rink-shaped drag guard 52, the outer peripheral edge of which is retained in a loose-fit state by a ring-shaped retainer 53 threadedly mounted at the front face of the spool 5 in such a manner that the spool will freely rotate without disturbing rotation of the drag knob 6.
At the front face of the drag guard 52, two guard plates 54 which draw a circle continuing to a spherical surface at the forward end of the drag knob 6 are protruding forwardly, thereby preventing the line from tangling on the drag knob 6 by the guard plates 54 provided on both sides of the drag knobs 6. The inside diameter of the drag guard 53 is a little larger than 21 7~976 the outside diameter of the drag knob 6, so that the drag guard 53 can freely be inserted and removed together with the spool 5.
In the spinning reel of the above-described constitution, when the spool 5 is to be replaced, the drag knob 6 is fully tightened as shown in Fig. 3, and then the spool 5 is turned to disengage the thread engagement sections 33 and 51. After all the thread engagement sections have been disengaged, the spool 5 is ready to be pulled out along the outer periphery of the drag knob 6. After the removal of the spool 5, a new spool 5 is inserted into engagement with, and tightened relative to, the fitting section 30 of the rotary drag body 3. Thereafter, the drag knob 6 is loosened to an appropriate position, in which the spinning reel is ready for use.
Since the spool 5 is releasably engaged and tightened on the outer periphery of the fitting section 30 of the rotary drag body 3 and the minimum inside diameter of the through hole 50 of the spool is larger than the maximum outside diameter of the drag knob 6 which is engaged with the forward end of the spool shaft 1, it is possible to remove the spool 5 from the outer periphery of the spool shaft 1 and easily replace it ~1 7897fi with a new one. Therefore, it has become unnecessary, unlike conventional ones, to remove the drag knob 6 at the time of replacement of the spool 5. It is possible to obviate such a trouble as the loss of the drag knob 6 at a fishing spot.
Also since the drag washer 4 can be replaced by removing the drag knob 6 from the forward end of the spool shaft 1 and pulling off the rotary drag body 3 and the spool 5 from the outer periphery of the fitting section 20 of the stationary drag body 2 as shown in Fig. 2, the replacement of the drag washer 4 can easily be conducted as compared with the conventional one which requires the use of a special tool to remove the drag washer retainer.
Furthermore, when replacing the drag washer 4, it is possible to perform drag washer replacement by removing the drag knob 6 from the spool shaft l and then by pulling the spool 5 and the rotary drag body 3 from the fitting section 20 of the stationary drag body 2.
It is possible to change drag characteristics by changing the combination of the materials of the resistance places 21 and 31 of both the stationary drag body 2 and the rotary drag body 3, thereby enabling the application of the drag characteristics of the spinning reel according to purposes of use.
For example, the resistance plates 21 and 31 mounted both sides of the drag washer 4, if produced both of stainless steel or reinforced resin, will slip with rotation of the spool 5, enabling to stabilize drag operation when the line is fed out from the spool 5.
It is also possible to obtain a great drag by using the resistance plates 21 and 31 produced of stainless steel and the drag washers 4 produced of cork material.
The use of the resistance plates 21 and 31 produced of reinforced resin and the drag washers 4 produced of cork material produces a less drag than the use of a combination of stainless steel resistance plates 21 and 31 and cork drag washers 4, but can obtain a stabilized drag characteristic.
It is also possible to obtain a stabilized drag by using the resistance plates 21 and 31 of stainless steel and the drag washer 4 of carbon fiber. The drag washer 4 is made of glass fiber sandwiched with carbon cloth and further impregnated with resin and set.
Furthermore, it is possible to obtain a drag characteristic of a stabilized drag even when the reinforced resin resistance plates 21 and 31 and carbon fiber drag washer 4 are used.
Hereinafter another embodiment of the present invention will be explained with reference to the accompanying drawings. A part of the embodiment that has been described will not be explained to prevent redundancy.
In the present embodiment, as shown in Figs. 4 to 7, a drag adjusting member 63 is engagedly mounted on the forward end of the spool shaft 1 mounted with the stationary drag body 2 in which the rotary drag body 3 is fitted; the drag spring 7 is elastically mounted between the drag adjusting member 63 and the forward end of the rotary drag body 3; and the spool 5 provided with the drag knob 6 which is engaged for operation with the drag adjusting member 63 is engaged with the rotary drag body 3.
An anti-reverse mechanism A is formed throughout the resistance plate 21 in the stationary drag body 2 and the resistance plate 31 of the rotary drag body 3 for the purpose of preventing reverse rotation of the spool 5.
The anti-reverse mechanism A is so adapted as to allow removal of the spool S from the rotary drag body 3 2 1 78q76 without turning the spool S if the drag is set at a lower value than the tightening force required to tighten the spool 5 to the rotary drum body 3 when the spool 5 is replaced. The spool can be replaced while maintaining the drag set by the anti-reverse mechanism A, thereby obviating such a trouble as drag re-setting every time the spool is replaced.
The drag adjusting member 63 engagedly mounted on the spool shaft 1 is a cylindrical part having a hexagonal cross section, and is engaged with the drag knob 6 in the spool 5. With the rotation of the drag knob 6,the drag adjusting member 63 moves in the axial direction of the spool shaft 1. There is provided a deep groove 62A formed as if surrounding the screw hole 61 in the axial direction from the rear end face of the drag adjusting member 63. In this deep groove 62A the drag spring 7 is inserted.
It should be noted that the sectional form of the drag adjusting member 63 is not limited to the hexagonal cross section and may be any form if it is engages with the drag knob 6, rotating together as one body.
The drag knob 6 rotatably mounted and locked on the forward end of the spool 5 is provided with a projection 66 on a disk-like base plate 64 having a larger diameter than the minimum diameter of the through hole 50 of the spool 5. On the outer peripheral surface of this projection 66 an operating section 67 is formed, extending to the vicinity of the outer periphery of the base plate 64, at right angles with the axial direction.
The retainer 53 engagedly fitted at the front face of the spool 6 rotatably retains the outer peripheral edge of the base plate 64.
In the rear end face of the drag knob 6 there is provided an engaging hole 68 which fits the sectional form of the drag adjusting member 63. In this engaging hole 68 is mounted the drag adjusting member 63 with the spool 5 engaged with the rotary drag body 3.
The spool 6 in the spinning reel of the above-described constitution, when replaced, can be pulled off in the axial direction by turning out of engagement with the rotary drag body 3 as shown in Fig. 7.
Subsequently, replacement can be accomplished by reversing the procedure of removal after fitting the spool to be mounted.
When the drag washer 4 requires replacement, the drag knob 6 is turned in a direction in which the drag will decrease; at this time the drag adjusting member 63 which is engagedly mounted on the spool shaft 1 turns as one body, allowing the removal of the drag washer 4 from the spool shaft 1 as shown in Fig. 6. The rotary drag member 3, being engaged with the spool 5, is drawn out as one body together with the spool 5. The drag washer 4 is exposed so as to be replaceable. A new drag washer 4 can be mounted by reversing the procedure of the above-described operation.
In either of the replacement of the spool 5 and the replacement of the drag washer 4, the drag knob 6, being freely rotatable and locked in relation to the spool 5, can be protected from such a trouble as falling or missing, ensuring safe handling of the spinning reel at a fishing place.
Also since the drag knob 6 is larger in diameter than the minimum diameter of the through hole of the spool 5, the drag knob 6 can be handled properly if a small-sized reel is employed.
Hereinafter another embodiment of the spool support mechanism of the spinning reel according to the present invention will be explained with reference to the accompanying drawings. Members explained in the above-described embodiment will not be explained to prevent redundancy.
The support spool mechanism of the spinning reel of the present embodiment is equipped with a ratchet mechanism R which composes the anti-reverse mechanism A
of such a design that, as shown in Figs. 8 to 11, when the rotary drag body 3 rotates in a direction in which the spool is removed from the rotary drag body 3, ranging from the resistance plate 21 in the stationary drag body 2 secured on the spool shaft 1 and the resistance plate 31 in the rotary drag body 3 fitted in the stationary drag body 2, the rotary dra~ body 3 is locked to the stationary drag body 2, and when the rotary drag body 3 rotates in a direction in which the spool is tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
The ratchet mechanism R comprises an engaging plate Rl which constitutes a part of the ratchet mechanism R
provided at the front end face of the resistance plate 21 in the stationary drag body 2 and an engaging section R2 which constitutes a part of the ratchet mechanism R
provided on the peripheral surface of the end portion of the resistance plate 31 in the rotary drag body 3.
The engaging plate Rl is made in a form of long piece having a round mounting bore Rll at center, and in 2 1 78~76 an approximately square form at the forward end on one side of the engaging plate Rl; the other end is tapered as it goes toward the forward end. Furthermore, a cylindrical member R12 which has the same inside diameter as the mounting bore Rll is formed as one body on the same axis as the mounting bore Rll.
The engaging plate Rl is attached by a screw E in the mounting bore Rll to the resistance plate 2A in the stationary drag body 2 in such a manner that it will rotate on the center of the axial direction.
A coil spring F is mounted on the cylindrical member R12 of the engaging plate Rl, with one end of the coil spring C attached on a projecting portion 21A
provided on the resistance plate 21 so that one end of the engaging plate Rl will constantly be pulled outward in the circumferential direction. Furthermore, the other end of the engaging plate Rl is held in contact with the projecting portion 21A provided on the resistance plate 21 to thereby restrict the rotation of the engaging plate Rl.
The engaging section R2 is composed of recessed and projecting portions R21 and R22 which continue along the peripheral side edge of the resistance plate 31. The forward end of the projecting portion R22 is inclined toward the inner periphery to form an inclined surface R23, and also the base portion of the inclined surface R23 is positioned outside of the forward end of the engaging plate Rl.
In the ratchet mechanism R of the above-described constitution, the engaging section Rl is engaged with, and disengaged from, the engaging plate R2, thereby restricting the rotation of the rotary drag body 3.
Therefore when the rotary drag body 3 rotates in a direction in which the spool 5 comes off from the rotary drag body 3, the rotary drag body 3 is locked to the stationary drag body 2.
Also when the rotary drag body 3 rotates in a direction in which the spool 5 is tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
To replace the spool 5 of the spinning reel of the above-described constitution, the spool 5 can be pulled off in the axial direction by turning to disengage from the rotary drag body 3 as shown in Fig. 11. At this time, the rotary drag body 3 is locked to the stationary drag body 2 by means of the ratchet mechanism R.
Subsequently the spool 5 to be installed is screwed into the rotary drag body 3.
Furthermore, to replace the drag washer 4, when the drag knob 6 is turned in a direction in which the drag is decreased as shown in Fig. 10, the drag knob 6 engaged with the spool shaft 1 comes off from the spool shaft 1. At this time, the rotary drag body 3, being engaged with the spool 5, is pulled out as one body together with the spool 5, so that the drag washer 4 is exposed out to be ready for replacement. The drag washer 4, after replacement, can be assembled by reversing the procedure described above. In this case, if the forward end position of the engaging plate Rl of the ratchet mechanism R is not properly aligned with the recessed section R21 of the ratchet mechanism R, the forward end of the engaging plate Rl is guided along the inclined surface R23 in the projecting portion R22 of the ratchet mechanism R.
According to the above-described constitution, since the spool 5 can be replaced by disengaging it without removing the drag knob 6, there will not occur such an accident that the drag knob 6 will drop to be lost at the time of replacement of the spool 5.
Also since the spool 5 can be replaced while holding the drag set by the operation of the anti-reverse mechanism A, it is possible to eliminate a trouble of setting the drag every time the spool 5 is replaced.
The anti-reverse mechanism A may be a one-way clutch W shown in Figs. 12 and 3.
The one-way clutch W is made in a form of flat non-circular cylinder and inserted between the outer peripheral surface of the fitting section 20 of the stationary drag body 2 and the inner peripheral surface of the fitting section 30 of the rotary drag body 3.
The one-way clutch W is releasably fitted in oval engagement in the rotary drag body 3 so as to turn as one body and as to move in and out of the opening section of the rotary drag body 3. Also, the one-way clutch W can be axially inserted in, and pulled out of, the stationary drag body 2.
The one-way clutch W is of such a design that when the rotation of the rotary drag body 3 turns the spool 5 in a direction in which the spool 5 will come off from the rotary drag body 3, the anti-reverse mechanism of the one-way clutch W acts on the stationary drag body 2 to lock the rotary drag body 3 to the stationary drag body 2; and when the rotation of the rotary drag body 3 turns the spool 5 in a direction in which the spool will be tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
By this constitution the same effect as in the case of the ratchet mechanism R is obtainable. Furthermore even if the one-way clutch has any trouble, the spinning reel instantly becomes usable by replacing the one-way clutch W.
Hereinafter another embodiment of the present invention will be explained with reference to the accompanying drawings. Same members as those in the above-described embodiment will not be explained to prevent redundancy.
According to the present embodiment, as shown in Figs. 14 to 17, the forward end of the spool shaft 1 which is fastened to the stationary drag body 2 is formed conical and a series of latching recesses 12 are provided in a ring form at the rear end of the conical section 11.
A projecting portion 35 is provided, along the axial direction of the rotary drag body 3, on the outer periphery of the rotary drag body 3 which is rotatably and axially removably mounted on the stationary drag body 2; and a groove 55 in which the projecting portion fits is provided in the through hole 50 of the spool 5 which is releasably mounted in the rotary drag body 3.
Thus the spool 5 is releasable and rotatable as one body with the rotary drag body 3.
There is provided a through hole 69 open in the axial direction through the drag knob 6 at the center of the bottom of the recess section 68 in which the drag knob 6 rotatably mounted and locked on the forward end of the spool 6 fits. And a ring spring S which fits in the latching recess 12 in the spool shaft 1 is mounted at the bottom surface of the engaging recess 68.
The ring spring S is produced of a metal wire which is bent in a circular form, and has a holding section S3 comprising straight levers Sl and S2 with its both ends bent parallelly in the diametrical direction of a circle. The width of the holding section S3 corresponds to the width of the latching recess 12 in the spool shaft 1.
The ring spring S thus formed is attached in the recess 68A formed at the bottom of the engaging recess 68 and is retained by a ring-shaped retaining plate B
inserted in the engaging recess 12 and by a clip ring C
for keeping the retaining plate B in position.
An expanding tube D inserted through from the through hole 69 in the drag knob 6 serves to spread the holding section S3 of the ring spring S; its front end protrudes out of the through hole, while the opposite faces on the diametral line of its rear end are tapered to form a tapered surface Dl, so that the expanding tube D will be fitted in between the straight levers composing the holding section S3 of the ring spring S, and that the holding section S3 will be expanded by pressing the expanding tube D to thereby remove the ring spring S from the latching recess 12.
To replace the spool 5 in the spinning reel of the above-described constitution, the expanding tube D is pressed to spread the holding section S3 to remove from the latching recess 12, and the spool 5 is ready to be pulled off in the axial direction. The spool 5, when installed, is fitted onto the spool shaft 1 to thereby expand the holding section S3 of the ring spring S by the conical section 11 on the forward end of the spool shaft 1. When the spool 5 is inserted through the conical section 11, the holding section S3 engages with the latching recess 12 in the spool shaft 1 to hold the spool 5 on the spool shaft 1.
When the drag washer 4 requires replacement, the drag knob 6 is turned in a direction in which the drag will decrease, and the drag adjusting member 63 in 21 7~976 engagement with the spool shaft 1 rotates as one body, coming off the spool shaft l; and when the spool 5 and the rotary drag body 3 are pulled off in order, the drag washer 4 is exposed to be ready for replacement as shown in Fig. 17. After the replacement of the drag washer 4, the spool 5 can be installed by reversing the above-described procedure.
According to the spinning reel of the aforesaid constitution, when the spool 5 and the drag washer require replacement, it is possible to prevent such a trouble as the drop and loss of the drag knob 6, ensuring safe handling of the spinning reel at a fishing spot.
Furthermore, even when the reel is small in size, the drag knob 6 can be handled easily, enabling the provision of spinning reels of various sizes from small to large types.
Furthermore, since installation and removal of the spool 5 can easily be performed without decreasing the drag, it is possible to replace the spool 5 very efficiently and restart fishing within a short time.
Having described specific preferred embodiments of the invention with reference to the accompanying drawings, it will be appreciated that the present ~ 1 78976 invention is not limited to those precise embodiments, and that various changes and modifications can be effected therein by one of ordinary skill in the art without departing from the scope and spirit of the invention as defined by the appended claims.
On the forward end of the main shaft 101 is engagedly mounted a drag knob 103, the end face of which is inserted into the opening section of the holding bore 104 to press a cluster of the drag washers 106 with a predetermined pressure. The amount of compression of the drag washers 106 is increased or decreased by turning this drag knob, thereby adjusting the amount of reversion resistance of the spool 102.
In the conventional spinning reel of the above constitution, the drag washers 106, being worn with frequent use, will require replacement after a predetermined period of time.
When the drag washers 106 of the above-described spinning reel are replaced, it is necessary to replace the cluster of the drag washers 106 by removing the drag knob 103 from the forward end of the main shaft 101, and then by removing the retainer 105 which is elastically fitted in the opening section of the holding bore 104 of the spool 101. This work, however, is very troublesome because it needs the use of a special tool to remove the retainer 105 carefully.
Furthermore, when replacement of the spool 102 is required in order to change the line, the drag knob 103 must be removed; therefore when spool replacement is to be done at a rocky place or at a fishing spot surrounded with water, the drag knob 103 thus removed will be clumsily handled to be lost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Hereinafter one embodiment of a spool supporting structure of a spinning reel according to the present invention will be explained with reference to the accompanying drawings.
Figs. 1 to 3 show one embodiment of the present invention, wherein a reference numeral 1 denotes a spool shaft of a known structure, which is stroked backward and forward by turning an unillustrated handle.
On the outer periphery of the spool shaft 1 a stationary drag body 2 is fitted.
The stationary drag body 2 is made of a stainless steel or other metal or of a plastic material, and is composed of a cylindrical fitting section 20 which is fitted on the outer periphery of the main shaft 1, and a 21 78~76 disk-shaped resistance plate 21 provided in a collar form on the outer peripheral surface of the rear end of the fitting section 20. The stationary drag body 2 is of such a constitution that a pin 10 is inserted into the fitting section 20 and the main shaft 1 so that the stationary drag body 2 and the main shaft 1 will rotate as one body. On the outer periphery of the fitting section 20 of the stationary drag body 2 a rotary drag body 3 is rotatably mounted. The rotary drag body 3, like the stationary drag body 2, is formed of a metal such as stainless steel or a plastic material, comprising a fitting section 30 fitted on the outer periphery of the fitting section 20 of the stationary drag body 2 and a disk-shaped resistance plate 31 mounted in a form of collar on the outer peripheral surface of the rear end of the fitting section 30. On the inner periphery of the fitting section 31 a brass sleeve 32 is fitted integrally and rotatable with respect to the outer peripheral surface of the fitting section 21 of the stationary drag body 2.
Both the resistance plates 21 and 32 of the stationary drag body 2 and the rotary drag body 3 which are mutually fitted as described above face to each other as shown in Fig. l; between these resistance plates 21 and 32 a drag washer 4 is inserted.
The drag washer 4 is a ring-type (doughnut-type) plate washer produced of cork or carbon fiber, and is fitted in a recess section 22 formed in the mating surface of the resistance plate 21 on the stationary side and held in this state between the resistance plates 21 and 32.
A spool 5 is engagedly fitted and firmly tightened on the outer peripheral surface of the fitting section 30 of the rotary drag body 3.
The spool 5 is a cylindrical body fitted to cover the outer periphery of the rotary drag body 3, and has a through hole 50 along the axial center section.
The spool 5 is provided with an internal thread section 51 in the inner periphery which is the smallest inside diameter section of the through hole 50. This internal thread section 51 is engaged with an external thread section 33 formed in the outer peripheral surface of the fitting section 30 of the rotary drag body 3.
Further, the spool 5 is so constituted that as the internal thread section 51 is tightened further, the rear end face 52 of the internal thread section 51 comes into contact with the front face of the resistance plate 31 of the rotary drag body 3, thereby locking the rotary drag body 3.
The internal thread section 51 of the spool 5 has a larger inside diameter than the outside diameter of a drag knob 6.
On the forward end portion of the spool shaft 1 the drag knob 6 is engagedly mounted.
The drag knob 6 formed substantially cylindrical is produced of aluminum or synthetic resin; in a screw hole 61 formed in the shaft center of one end face, the forward end of the main shaft 1 is engaged, so that the spool can be moved for adjustment in the axial direction of the main shaft 1 by turning the drag knob 6 in both the normal and reverse directions.
The outside diameter of the drab knob 6 formed substantially cylindrical is made somewhat smaller than the inside diameter of the internal thread section 51 which is the smallest inside diameter of the spool 5.
Thus there exists no interference between the inner peripheral surface of the spool 5 and the outer peripheral surface of the drag knob 6, thereby allowing the removal and mounting of the spool 5 in relation to the fitting section-30 of the rotary drag body 3 without removing the drag knob 6 from the forward end of the main shaft 1.
Also, around the screw hole 61 in one end face of the drag knob 6 is formed a circular deep groove 62, in which a drag spring 7 is inserted.
The drag spring 7 is an elastic body of a coil spring produced of a relatively thick wire, for pressing the resistance plate 30 of the rotary drag body 3 against the resistance plate 20 of the stationary drag body 2. The drag spring 7 is elastically fitted in a compressed state between the deep groove 62 of the drag knob 6 and the end face of the fitting section 30 of the rotary drag body 3. It should be noticed that the elastic body for pressing the resistance plate 20 is not limited to the above-mentioned drag spring 7 formed in the shape of coil spring and may be any form that can variably adjust the pressure of the resistance plate 20 by moving the drag knob 6.
As described above, a metal washer 23 and a ring-shaped locking plate 8 of Teflon resin are fitted on the outer periphery of the forward end portion of the fitting section 20 of the stationary drag body 2 with which the end of the drag spring 7 is in contact.
2~ 7~3976 The locking plate 8 has an approximately oval inner bore, and a narrow part of the inner bore is fitted in a slot formed oppositely to the outer peripheral surface of the fitting section 20, thereby locking in relation to the stationary drag body 2.
The locking plate 8 is loosely fitted in a groove 34 provided in the inner periphery of the opening section on the forward end side of the fitting section 30 of the rotary drag body 3, and a set ring 9 is elastically fitted in the groove 34 to thereby develop locking action in the axial direction.
At the front of the spool 5 is provided a rink-shaped drag guard 52, the outer peripheral edge of which is retained in a loose-fit state by a ring-shaped retainer 53 threadedly mounted at the front face of the spool 5 in such a manner that the spool will freely rotate without disturbing rotation of the drag knob 6.
At the front face of the drag guard 52, two guard plates 54 which draw a circle continuing to a spherical surface at the forward end of the drag knob 6 are protruding forwardly, thereby preventing the line from tangling on the drag knob 6 by the guard plates 54 provided on both sides of the drag knobs 6. The inside diameter of the drag guard 53 is a little larger than 21 7~976 the outside diameter of the drag knob 6, so that the drag guard 53 can freely be inserted and removed together with the spool 5.
In the spinning reel of the above-described constitution, when the spool 5 is to be replaced, the drag knob 6 is fully tightened as shown in Fig. 3, and then the spool 5 is turned to disengage the thread engagement sections 33 and 51. After all the thread engagement sections have been disengaged, the spool 5 is ready to be pulled out along the outer periphery of the drag knob 6. After the removal of the spool 5, a new spool 5 is inserted into engagement with, and tightened relative to, the fitting section 30 of the rotary drag body 3. Thereafter, the drag knob 6 is loosened to an appropriate position, in which the spinning reel is ready for use.
Since the spool 5 is releasably engaged and tightened on the outer periphery of the fitting section 30 of the rotary drag body 3 and the minimum inside diameter of the through hole 50 of the spool is larger than the maximum outside diameter of the drag knob 6 which is engaged with the forward end of the spool shaft 1, it is possible to remove the spool 5 from the outer periphery of the spool shaft 1 and easily replace it ~1 7897fi with a new one. Therefore, it has become unnecessary, unlike conventional ones, to remove the drag knob 6 at the time of replacement of the spool 5. It is possible to obviate such a trouble as the loss of the drag knob 6 at a fishing spot.
Also since the drag washer 4 can be replaced by removing the drag knob 6 from the forward end of the spool shaft 1 and pulling off the rotary drag body 3 and the spool 5 from the outer periphery of the fitting section 20 of the stationary drag body 2 as shown in Fig. 2, the replacement of the drag washer 4 can easily be conducted as compared with the conventional one which requires the use of a special tool to remove the drag washer retainer.
Furthermore, when replacing the drag washer 4, it is possible to perform drag washer replacement by removing the drag knob 6 from the spool shaft l and then by pulling the spool 5 and the rotary drag body 3 from the fitting section 20 of the stationary drag body 2.
It is possible to change drag characteristics by changing the combination of the materials of the resistance places 21 and 31 of both the stationary drag body 2 and the rotary drag body 3, thereby enabling the application of the drag characteristics of the spinning reel according to purposes of use.
For example, the resistance plates 21 and 31 mounted both sides of the drag washer 4, if produced both of stainless steel or reinforced resin, will slip with rotation of the spool 5, enabling to stabilize drag operation when the line is fed out from the spool 5.
It is also possible to obtain a great drag by using the resistance plates 21 and 31 produced of stainless steel and the drag washers 4 produced of cork material.
The use of the resistance plates 21 and 31 produced of reinforced resin and the drag washers 4 produced of cork material produces a less drag than the use of a combination of stainless steel resistance plates 21 and 31 and cork drag washers 4, but can obtain a stabilized drag characteristic.
It is also possible to obtain a stabilized drag by using the resistance plates 21 and 31 of stainless steel and the drag washer 4 of carbon fiber. The drag washer 4 is made of glass fiber sandwiched with carbon cloth and further impregnated with resin and set.
Furthermore, it is possible to obtain a drag characteristic of a stabilized drag even when the reinforced resin resistance plates 21 and 31 and carbon fiber drag washer 4 are used.
Hereinafter another embodiment of the present invention will be explained with reference to the accompanying drawings. A part of the embodiment that has been described will not be explained to prevent redundancy.
In the present embodiment, as shown in Figs. 4 to 7, a drag adjusting member 63 is engagedly mounted on the forward end of the spool shaft 1 mounted with the stationary drag body 2 in which the rotary drag body 3 is fitted; the drag spring 7 is elastically mounted between the drag adjusting member 63 and the forward end of the rotary drag body 3; and the spool 5 provided with the drag knob 6 which is engaged for operation with the drag adjusting member 63 is engaged with the rotary drag body 3.
An anti-reverse mechanism A is formed throughout the resistance plate 21 in the stationary drag body 2 and the resistance plate 31 of the rotary drag body 3 for the purpose of preventing reverse rotation of the spool 5.
The anti-reverse mechanism A is so adapted as to allow removal of the spool S from the rotary drag body 3 2 1 78q76 without turning the spool S if the drag is set at a lower value than the tightening force required to tighten the spool 5 to the rotary drum body 3 when the spool 5 is replaced. The spool can be replaced while maintaining the drag set by the anti-reverse mechanism A, thereby obviating such a trouble as drag re-setting every time the spool is replaced.
The drag adjusting member 63 engagedly mounted on the spool shaft 1 is a cylindrical part having a hexagonal cross section, and is engaged with the drag knob 6 in the spool 5. With the rotation of the drag knob 6,the drag adjusting member 63 moves in the axial direction of the spool shaft 1. There is provided a deep groove 62A formed as if surrounding the screw hole 61 in the axial direction from the rear end face of the drag adjusting member 63. In this deep groove 62A the drag spring 7 is inserted.
It should be noted that the sectional form of the drag adjusting member 63 is not limited to the hexagonal cross section and may be any form if it is engages with the drag knob 6, rotating together as one body.
The drag knob 6 rotatably mounted and locked on the forward end of the spool 5 is provided with a projection 66 on a disk-like base plate 64 having a larger diameter than the minimum diameter of the through hole 50 of the spool 5. On the outer peripheral surface of this projection 66 an operating section 67 is formed, extending to the vicinity of the outer periphery of the base plate 64, at right angles with the axial direction.
The retainer 53 engagedly fitted at the front face of the spool 6 rotatably retains the outer peripheral edge of the base plate 64.
In the rear end face of the drag knob 6 there is provided an engaging hole 68 which fits the sectional form of the drag adjusting member 63. In this engaging hole 68 is mounted the drag adjusting member 63 with the spool 5 engaged with the rotary drag body 3.
The spool 6 in the spinning reel of the above-described constitution, when replaced, can be pulled off in the axial direction by turning out of engagement with the rotary drag body 3 as shown in Fig. 7.
Subsequently, replacement can be accomplished by reversing the procedure of removal after fitting the spool to be mounted.
When the drag washer 4 requires replacement, the drag knob 6 is turned in a direction in which the drag will decrease; at this time the drag adjusting member 63 which is engagedly mounted on the spool shaft 1 turns as one body, allowing the removal of the drag washer 4 from the spool shaft 1 as shown in Fig. 6. The rotary drag member 3, being engaged with the spool 5, is drawn out as one body together with the spool 5. The drag washer 4 is exposed so as to be replaceable. A new drag washer 4 can be mounted by reversing the procedure of the above-described operation.
In either of the replacement of the spool 5 and the replacement of the drag washer 4, the drag knob 6, being freely rotatable and locked in relation to the spool 5, can be protected from such a trouble as falling or missing, ensuring safe handling of the spinning reel at a fishing place.
Also since the drag knob 6 is larger in diameter than the minimum diameter of the through hole of the spool 5, the drag knob 6 can be handled properly if a small-sized reel is employed.
Hereinafter another embodiment of the spool support mechanism of the spinning reel according to the present invention will be explained with reference to the accompanying drawings. Members explained in the above-described embodiment will not be explained to prevent redundancy.
The support spool mechanism of the spinning reel of the present embodiment is equipped with a ratchet mechanism R which composes the anti-reverse mechanism A
of such a design that, as shown in Figs. 8 to 11, when the rotary drag body 3 rotates in a direction in which the spool is removed from the rotary drag body 3, ranging from the resistance plate 21 in the stationary drag body 2 secured on the spool shaft 1 and the resistance plate 31 in the rotary drag body 3 fitted in the stationary drag body 2, the rotary dra~ body 3 is locked to the stationary drag body 2, and when the rotary drag body 3 rotates in a direction in which the spool is tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
The ratchet mechanism R comprises an engaging plate Rl which constitutes a part of the ratchet mechanism R
provided at the front end face of the resistance plate 21 in the stationary drag body 2 and an engaging section R2 which constitutes a part of the ratchet mechanism R
provided on the peripheral surface of the end portion of the resistance plate 31 in the rotary drag body 3.
The engaging plate Rl is made in a form of long piece having a round mounting bore Rll at center, and in 2 1 78~76 an approximately square form at the forward end on one side of the engaging plate Rl; the other end is tapered as it goes toward the forward end. Furthermore, a cylindrical member R12 which has the same inside diameter as the mounting bore Rll is formed as one body on the same axis as the mounting bore Rll.
The engaging plate Rl is attached by a screw E in the mounting bore Rll to the resistance plate 2A in the stationary drag body 2 in such a manner that it will rotate on the center of the axial direction.
A coil spring F is mounted on the cylindrical member R12 of the engaging plate Rl, with one end of the coil spring C attached on a projecting portion 21A
provided on the resistance plate 21 so that one end of the engaging plate Rl will constantly be pulled outward in the circumferential direction. Furthermore, the other end of the engaging plate Rl is held in contact with the projecting portion 21A provided on the resistance plate 21 to thereby restrict the rotation of the engaging plate Rl.
The engaging section R2 is composed of recessed and projecting portions R21 and R22 which continue along the peripheral side edge of the resistance plate 31. The forward end of the projecting portion R22 is inclined toward the inner periphery to form an inclined surface R23, and also the base portion of the inclined surface R23 is positioned outside of the forward end of the engaging plate Rl.
In the ratchet mechanism R of the above-described constitution, the engaging section Rl is engaged with, and disengaged from, the engaging plate R2, thereby restricting the rotation of the rotary drag body 3.
Therefore when the rotary drag body 3 rotates in a direction in which the spool 5 comes off from the rotary drag body 3, the rotary drag body 3 is locked to the stationary drag body 2.
Also when the rotary drag body 3 rotates in a direction in which the spool 5 is tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
To replace the spool 5 of the spinning reel of the above-described constitution, the spool 5 can be pulled off in the axial direction by turning to disengage from the rotary drag body 3 as shown in Fig. 11. At this time, the rotary drag body 3 is locked to the stationary drag body 2 by means of the ratchet mechanism R.
Subsequently the spool 5 to be installed is screwed into the rotary drag body 3.
Furthermore, to replace the drag washer 4, when the drag knob 6 is turned in a direction in which the drag is decreased as shown in Fig. 10, the drag knob 6 engaged with the spool shaft 1 comes off from the spool shaft 1. At this time, the rotary drag body 3, being engaged with the spool 5, is pulled out as one body together with the spool 5, so that the drag washer 4 is exposed out to be ready for replacement. The drag washer 4, after replacement, can be assembled by reversing the procedure described above. In this case, if the forward end position of the engaging plate Rl of the ratchet mechanism R is not properly aligned with the recessed section R21 of the ratchet mechanism R, the forward end of the engaging plate Rl is guided along the inclined surface R23 in the projecting portion R22 of the ratchet mechanism R.
According to the above-described constitution, since the spool 5 can be replaced by disengaging it without removing the drag knob 6, there will not occur such an accident that the drag knob 6 will drop to be lost at the time of replacement of the spool 5.
Also since the spool 5 can be replaced while holding the drag set by the operation of the anti-reverse mechanism A, it is possible to eliminate a trouble of setting the drag every time the spool 5 is replaced.
The anti-reverse mechanism A may be a one-way clutch W shown in Figs. 12 and 3.
The one-way clutch W is made in a form of flat non-circular cylinder and inserted between the outer peripheral surface of the fitting section 20 of the stationary drag body 2 and the inner peripheral surface of the fitting section 30 of the rotary drag body 3.
The one-way clutch W is releasably fitted in oval engagement in the rotary drag body 3 so as to turn as one body and as to move in and out of the opening section of the rotary drag body 3. Also, the one-way clutch W can be axially inserted in, and pulled out of, the stationary drag body 2.
The one-way clutch W is of such a design that when the rotation of the rotary drag body 3 turns the spool 5 in a direction in which the spool 5 will come off from the rotary drag body 3, the anti-reverse mechanism of the one-way clutch W acts on the stationary drag body 2 to lock the rotary drag body 3 to the stationary drag body 2; and when the rotation of the rotary drag body 3 turns the spool 5 in a direction in which the spool will be tightened to the rotary drag body 3, the rotary drag body 3 rotates in relation to the stationary drag body 2.
By this constitution the same effect as in the case of the ratchet mechanism R is obtainable. Furthermore even if the one-way clutch has any trouble, the spinning reel instantly becomes usable by replacing the one-way clutch W.
Hereinafter another embodiment of the present invention will be explained with reference to the accompanying drawings. Same members as those in the above-described embodiment will not be explained to prevent redundancy.
According to the present embodiment, as shown in Figs. 14 to 17, the forward end of the spool shaft 1 which is fastened to the stationary drag body 2 is formed conical and a series of latching recesses 12 are provided in a ring form at the rear end of the conical section 11.
A projecting portion 35 is provided, along the axial direction of the rotary drag body 3, on the outer periphery of the rotary drag body 3 which is rotatably and axially removably mounted on the stationary drag body 2; and a groove 55 in which the projecting portion fits is provided in the through hole 50 of the spool 5 which is releasably mounted in the rotary drag body 3.
Thus the spool 5 is releasable and rotatable as one body with the rotary drag body 3.
There is provided a through hole 69 open in the axial direction through the drag knob 6 at the center of the bottom of the recess section 68 in which the drag knob 6 rotatably mounted and locked on the forward end of the spool 6 fits. And a ring spring S which fits in the latching recess 12 in the spool shaft 1 is mounted at the bottom surface of the engaging recess 68.
The ring spring S is produced of a metal wire which is bent in a circular form, and has a holding section S3 comprising straight levers Sl and S2 with its both ends bent parallelly in the diametrical direction of a circle. The width of the holding section S3 corresponds to the width of the latching recess 12 in the spool shaft 1.
The ring spring S thus formed is attached in the recess 68A formed at the bottom of the engaging recess 68 and is retained by a ring-shaped retaining plate B
inserted in the engaging recess 12 and by a clip ring C
for keeping the retaining plate B in position.
An expanding tube D inserted through from the through hole 69 in the drag knob 6 serves to spread the holding section S3 of the ring spring S; its front end protrudes out of the through hole, while the opposite faces on the diametral line of its rear end are tapered to form a tapered surface Dl, so that the expanding tube D will be fitted in between the straight levers composing the holding section S3 of the ring spring S, and that the holding section S3 will be expanded by pressing the expanding tube D to thereby remove the ring spring S from the latching recess 12.
To replace the spool 5 in the spinning reel of the above-described constitution, the expanding tube D is pressed to spread the holding section S3 to remove from the latching recess 12, and the spool 5 is ready to be pulled off in the axial direction. The spool 5, when installed, is fitted onto the spool shaft 1 to thereby expand the holding section S3 of the ring spring S by the conical section 11 on the forward end of the spool shaft 1. When the spool 5 is inserted through the conical section 11, the holding section S3 engages with the latching recess 12 in the spool shaft 1 to hold the spool 5 on the spool shaft 1.
When the drag washer 4 requires replacement, the drag knob 6 is turned in a direction in which the drag will decrease, and the drag adjusting member 63 in 21 7~976 engagement with the spool shaft 1 rotates as one body, coming off the spool shaft l; and when the spool 5 and the rotary drag body 3 are pulled off in order, the drag washer 4 is exposed to be ready for replacement as shown in Fig. 17. After the replacement of the drag washer 4, the spool 5 can be installed by reversing the above-described procedure.
According to the spinning reel of the aforesaid constitution, when the spool 5 and the drag washer require replacement, it is possible to prevent such a trouble as the drop and loss of the drag knob 6, ensuring safe handling of the spinning reel at a fishing spot.
Furthermore, even when the reel is small in size, the drag knob 6 can be handled easily, enabling the provision of spinning reels of various sizes from small to large types.
Furthermore, since installation and removal of the spool 5 can easily be performed without decreasing the drag, it is possible to replace the spool 5 very efficiently and restart fishing within a short time.
Having described specific preferred embodiments of the invention with reference to the accompanying drawings, it will be appreciated that the present ~ 1 78976 invention is not limited to those precise embodiments, and that various changes and modifications can be effected therein by one of ordinary skill in the art without departing from the scope and spirit of the invention as defined by the appended claims.
