Abstract

A spinning reel is provided with a reel body 2, a rotor 3 and a spool 4. The rotor 3 is supported on the front of the reel body 2 with freedom to rotate, and has a first arm portion 31 and a second arm portion 32 which are located facing each other such that the rotating spindle is interposed between them, a first bail support member 40 which is fitted to the tip of the first arm portion 31 and which has at its tip a line roller 41, a second bail support member 43 which is fitted to the tip of the second arm portion 32, and a bail 45. The spool is located between the first arm portion 31 and the second arm portion 32. Further, the distance from the rotational axis X of the rotor 3 to the center of gravity of the second bail support member 43 is longer than the distance from the rotational axis X of the rotor 3 to the center of gravity of the first bail support member 40 including the line roller 41. The distance (R2 fig 5) is greater than the distance (R3), these being the distances from the axis X to the respective bail arm support pivot faces (31b and 32b). Thus imbalance during rotation is suppressed without increasing the weight of the arm portion side opposite the arm on which the line roller is provided.

Description

2318493 nTLE OF TE RWE11MON SPRG REEL

BACKGROUND OF TH1 DMBM0N

A) FIELD OFTHE 2,R7ENTION

The present invention relates to a spinning reel for a fishing rod and in particular to a spinning reel in which a rotor, which has a pair of arm portions located opposite each other, is supported on the spinning reel body with freedom to rotate.

B) DESCRIMON OF TIE RELATED ART In general, spinning reels include a reel body, a rotor which is supported on the reel body with freedom to rotate and a spindle on which fishin- line is wound.'The rotor usually has a first arm portion and a second arm portion which are located facing each other such that the rotational spindle is between them, swinging arms which are fixed to the tips of each arm portion with freedom to swine, and a bail which is provided between the two swinging arms. The bail swings together with the two swinging arms and cah adopt a line release state and a line winding state. Further, a line guide portion which guides the fishing line is provided at the tip of one of the swinging arms. The line guiding portion generally consists of a rotating member known as a line roller.

Further, when the fishing line is being wound, the fishing line is lead to the line guiding portion via the bail and is wound from the line guiding portion onto the spool.

problems to be overcome by the invention Since, as outlined above, a line roller is provided at the tip of the 1 first arm portion, the overall center of gTavity of the members on the first arm portion side is positioned relatively forward. Thus even if a balance is provided on the second arm portion side, it is difficult to unify the overall center of gravity of the members an the first am portion side and the overall center of gravity of the members including the balance on the second arm portion side in the axial direction.

Therefore, in a conventional spinning reel, imbalance during rotation is not eliminated even if a balance is provided on the second arm portion side, and it is difficult to obtain a smooth winding action.

Further, it has been proposed to eliminate imbalance during rotation by increasing the weight of the swinging arm at the tip of the second arm portion to make it function as a balance, And with a conventional spinning reel in which the weight of the swinging arm is increased, the overall weight of the rotor is inevitably increased.

Furthermore, Japanese laying-open utility model gazette no. S52-55892 proposes forming each arm separately from the rotor body and making it possible to vary the position of each arm in the radial direction. In this case it is possible to suppress imbalance during rotation by displacing one of the arms. There are problems, however, in that the number of components is increased and the overall weight of the rotor is increased.

DETA= DESC=ON OF THE PMERRED EMBODUMJTS The spinning reel according to one embodiment of the present invention, shown in Figure 1, is provided with a reel body 2 which is provided with a handle 1, a rotor 3 which is supported with freedom to rotate at the front of the reel body 2, and a spool 4 which is located at the front of the rotor 3 and on which fishing line is wound.

The reel body 2 has a body za, and an attachment 2b for attaching the spinning reel to a fishing rod is formed at the top. A rotor drive mechanism 5 for rotating the rotor 3, and a level wind mechanism 6 for winding fishing line uniformly onto the spool 4 by moving the spool 4 7 backwards and forwards along a rotational axis X, are provided inside the body 2a.

The rotor drive mechanism 5 has a master gear 11 which rotates together with a spindle 10 to which the handle 1 is secured, and a pinion gear 12 which engages with the master gear 11. The pinion gear 12 is formed in a cylindrical shape, and its front 12a passes through the center of the rotor 3 and extends on the spool 4 side. The rear end of the pinion gear 12 is supported with freedom to rotate in a bearing 15 which is formed integrally with the body 2a of the reel body 2, and the front 12a is supported in a ball bearing 13 which is supported in the body 2a. A spool spindle 14 is provided passing through the center of the pinion gear 12 with freedom to mbve backwards and forwards along the rotational axis X. As shown in an enlargement in Figure 2, a gap A is formed between the inner diameter of the pinion gear 12 and the outer diameter of the spool spindle 14. Further, the inner diameter 12b at the tip of the front 12a of the pinion gear 12 has a smaller diameter than other parts, and is a support for the spool spindle 14 As shown in an enlargement in Figure 2, a first support 15a which supports the spool spindle 14, and a second support 15b which su pports the pinion gear 12 are formed concentrically in the bearing 15.

With such a construction of the bearing 15, the pinion gear 12 is reliably supported in the second support 15b, and the spool spindle 14 is also supported reliably in the first support 15a of the bearing 15. It is thus possible to avoid contact between the inner circumference of the pinion gear 12 and the outer circumference of the support spindle' 14 in 8 conjunction with the abovementioned gap A, and thus resistance due to friction is reduced.

With reference to Fig. 1, the level wind drive inechanisrn 6 has a helical grooved spindle 16 which is located below the spool spindle 14, a 5, slider 17 which moves backwards and forwards along the helical grooved spindle 16, and a gear 18 which is secured. to the tip of the helical grooved spindle 16. The helical grooved spindle 16 is located parallel to the spool spindle 14 and is supported with freedom to rotate in the body 2a. Further, a helical groove 16a is formed in the outer circumference of the helical grooved spindle 16. Further, the slider 17 is engaged with the helical groove 16a, and the rear end of the spool spindle 14 is secured to the top' end of the slider 17. Further, the gear 18 is engaged with the pinion gear 12- By means of such a construction, the helical grooved spindle 16 is rotated by means of the pinion gear 12, the slider 17 moves backwards and forwards, and the spool spindle 14 and the spool 4 are moved backwards and forwards.

Further, an operating lever 21 for operating a ratchet mecll which is provided at the front of the reel body 2 is provided at the rear of the body 2a. The ratchet mechanism 20 and the operating lever 21 are connected via a first rotating spindle 22 and a second rotating spindle 23. As shown in Figure 3, the operating lever 21 comprises a conn ecting portion 21a to which the rear end of the second rotating spindle 23 is connected, and an operating portion 21b, which comes into contact with the finger of the operator. A slot 21c into which the rear end of the second rotating spindle 23 is inserted is formed in the 9 connecting Portion 21a, and a screw hole 21d into which is inserted a screw for securing the second rotating spindle 23 which has been inserted into the connecting portion 21a is formed in the side. One side of the slot 21c in the operating lever 21 is open, and thus during assembly the operating lever 21 can be attached as the final process, and thus the attachment operation is simpIffied.

Fuxthermore, the natchet Mechanisrn 20 is switched over between an operational state and a non-operational state by means of the operating lever 21. In the operational state, the handle 1 is prevented froM rotating in the direction which lets line out On the other hand, in the non-operational state, the handle 1 is permitted to rotate in both the direction which winds line in and the direction which lets Itne out With reference again to Figs. 1 and to Fig. 5, the rotor 3 is formed from any of a variety of materials ' for instance resin or is formed from die cast alumin=, and it has a cylindrical portion 30, and a first arm portion 31 and a second arm portion 32 which are provided facing each other on the sides of the cylindrical portion 30. The cylindrical portion and the two arm portions 31 and 32 are formed integrally. A front wall 33 (Flig. 1) is formed at the front of the cylindrical portion 30, and a boss 33a is formed in the center of the front wall 33. A through-hole is formed in the center of the boss 33a, and the front 12a of the pinion gear 12 and the spool spindle 14 pass through the through-hole. Further, a screw portion 12c is formed at the tip of the pinion gear 12 which extends through the front wall 33, and a nut 34 is screwed onto the screw portion 12c.

Details of the components of the nut 34 are shown in an exploded view in Fig ure 4_ As shown in this figure, m the circumference of nut 34 a retainer 35 comprising an annular plate member is secured to the front wall 33 by means of a screw 36. A screw hole 33b into which the screw 36 is secured is formed in the front wall 33. A locking hole 35a into which the corj, ers of the nut 34 can latch is formed in the center of the retainer 35. Further, a hole 35b through which the screw 36 passes, and arc-shaped slots 35c and 35d are formed in the circumference of the retainer 35. With such a nut securing construction, the screw 36 is secured, and thus this causes imbalance to occur during rotation.

However, the screw portion 36a of the screw 36 is canceled out by the screw hole 33b, and the wei-ht of the head 36b of the s= 36 is canceled out by the slots 35c and 35d in the retainer 35, and thus imbalance due to the screw 36 during rotation is suppressed.

Referring again to Figs. 5 and 6, a first bail support member 40 is attached to the periphery of the tip (front) of the first arm portion 31 with freedom to pivot about a pivot pin 31P, which extends through the first bail support member 40 and the end of the first arm portion 31. A line roller 41 for guiding fishing line onto the spool 4 is rotatably fitted to the tip of the first bail support member 40. As shown in Figure 1 and Figure 5, the second arm portion 32 is inclined such that it becomes further away from the. rotational axis X of the rotor 3 as one moves from the base to the tip. Further, a second bail support member 43 is fitted to the periphery of the tip thereof with freedom to pivot with respect to a.seat face 32b, for instance, about a pin (not shown), but similar to the pin 31P described above. Here, the second arm portion 32 is inclined such that its tip is further away from the rotational axis X and thus the distance R2 from the rotational axis X to the second bail support member attachment scat face 32b of the second arm portion 32 is longer than the distance RI from the rotational axis X to the first bail support member attachment seat face 31b of the first arm portion 31.

Therefore the distance from the rotational axis X to the center of gravity of the second bail support member 43 is longer than the distance from the rotational axis X to the center of gravity of the first bail support member 40 including the line roller 41. On the other hand, the distances from the rotational axis X to the respective bases of the first arm portion 31 and the second arm portion 32 are both an equal distance R3. The outer surface of the rear end 43a of the second bail support member 43 is only connected to the outer surface of the second arm portion 32 and a fishline (not shown) wound by rotation of the rotor 3 generally is urged into engagement with the line roller 41 and is generally not caught by the rear end of the second bail support member 43.

A bail 45 is provided between the fine roller 41, which is provided at the tip of the first bail support member 40, and the second bail support member 43, as shown in Fig. 1. A space is formed inside the first arm portion 31, and a toggle mechanism 46 is located in this space. By means of this toggle mechanism 46, the first bail support member 40, the second bail support member 43 and the baiI 45 are arranged such that they can be pivoted over and maintained in 2 positions, namely a line winding state and a line release state.

12 The internal space in which the toggle mechanism 46 is located is covered by 'a cover 31a which is attached to the periphery of the first arn, portion 31. The cover 31a may be, for instance formed from die cast zinc with a larger relative density than the resin or alurninum frorn which the rotor 3 is formed, and as is clear from Figure 6, its center of gravity is on the side of the rotational axis X on which the bail 45 is positioned when in the line winding state, and is on ihe reel body side (rear) of the first bail support member 40. Such a cover 31a functions as a balancer, and the overall center of gravity of members fitted to the first arm portion 31 is displaced to the reel body side in comparison with the case in which the cover 31a is not providecl Further, as shown m Figure 6, the tips of the first arm pardon 31 and the second arm portion 32 are positioned on the side of the rotational axis X on which the bail 45 is positioned when in the line release state, and the bases thereof are positioned on the reverse side an which the bail 45 is positioned when in the line winding state. Further, the sliding center of the second bail support member 43 is displaced by D frorn the rotational axis X on the line release state side.

The spool 4 is positioned between the first arm portion 31 and the second arm portion 32 of the rotor 3, and is fitted to the tip of the spool spindle 14 via a drag device 50 (Fig. 1). As shown in Figure 7, the spool 4 has a cylindrical skirt portion 4a which is formed at the rear end, a line winding barrel portion 4b which is disposed to the front of the skirt portion 4a, and a flange portion 4c which is formed at the tip of the line winding barrel portion 4b. The cylindrical portion 30 of the rotor 3 is 13 inserted into the skirt portion 4a. A space is also formed inside the line winding barrel portion 4b, and a multi-plate frictional drag device 50 is provided in this space. An adjustment knob 51 for adjusting the drag force is provided at the front of the drag device 50. A cylindrical press portion Sla is formed at the rear end of the adjustment knob 51, and a nut member 52 is embedded inside the cylindrical portion 51a. The nut member 52 screws onto a screw portion formed at the tip of the spool spindle 14. Further, a ball bearing 53 is located between the periphery of the cylindrical portion 51a of the adjustment knob 51 and the inside of the line winding barrel 4b of the spool 4.

With such a construction, the pressing force on the plates constituting the drag device 50 can be varied by adjusting the tightening of the adjustment 51, and the drag force can be adjusted. Further, since the adjustment knob 51 and the spool are supported by the ball bearing 53, it is possible to prevent the spool 4 from shalcing even when the drag force is slackened.

Further, as shown in Figure 7, a line fixing guide 54 is provided on the outer surface of the skirt portion 4a of the spool 4. A portion of the line fixing guide 54 extends into hole 4d (refer to Figure 8) formed in the spool 4 and is fixed by a screw (not shown) to the inside of the skirt portion 4a. Projections 4e which project outward are f ormed at the edges of the hole 4d on both sides of the line ELxing guide 54. As shown in Figure 8, with such a construction it is possible a line W reliably by means of the pmjections 4e and the line fixing guide 54 when the line W is latched into the line fixing guide 54 and to prevent the line 14 escaping from the line fixing guide 54.

A description of the action of the present embodiment will now be given paying attention mainly to line winding.

During line winding, the bail 45 is pivoted over to the line winding state side. If the handle 1 is rotated in this state, the rotational force is transmitted via the handle spindle 10 and the master gear 11 to the pinion gear 12. The rotational force transmitted to the pinion gear 12 is Umnsmitted to the rotor 3 via the front portion 12a of the pinion gear.

On the other hand, the helical grooved spindle 16 is rotated by the gear 18 which is engaged in the pinion gear 12, and the slider 17 which is engaged in the helical groove 16a of the helical grooved spindle 16 moves backwards and forwards. Thus'the spool spindle 14 and the spool 4 shuttle backwards and forwards along the rotational axis X and the line W which is guided by the bail 45 and the line roller 41 onto the spool 4 is wound uniformly backwards and forwards onto the fine winding barrel portion 4b.

Here, if the rotor 3 is rotated then the bail 45 similarly rotates.

During line winding, the bail 45 is positioned on one side (the line winding state side), and thus if, for example, the arm portions 31 and 32 were located such that the central axis of swinging of the bail support members 40 and 43 passes through the rotational axis X, then imbalance resulting from the bail 45 would occur during rotation. Thus in the present embodiment, as outlined above, the central axis of swinging is displaced by the distance D (Fig. 6) from the rotational axis X on the line release state side. Imbalance due to the bail 45 is eliminated by this displacement. Further, the bases of the two arm portions 31 and 332 are located on the side with the bail in the line winding state, and the cover 31a of the first arm portion 31 is preferably formed from die cast zinc.

Thus the overall center of gravity of the bail 45, the line roller 40 and the cover 31a is located on the reel body side (rear). Thus balancers are provided on opposite sides, and the suppression of imbalance during rotation is simple.

Further, the Ent bail support member 40 including the line roller 41 is provided on the first arm portion 31, and thus irL order to eliminate imbalance resulting frorn the weights thereof during rotation, a balance means such as a weight is also required an the factng second arm portion 32 side. In the present embodiment, the second bail support member 40 is positioned further from the rotational a)ds X than the first bail support member 43. Thus even though the weight of the second bail support member 43 is small, its centrifugal force is large, and it is possible to reduce imbalance during rotation resulting from the line roller 41, for example, due to the small second bail support member 43.

Thus for the same reason it is not necessary to project the second bail support member 43 outward greatly, and it is thus possible to reduce the risk of catching of the line at the rear end of the second bail support member 43.

Moreover, the base of the second arm portion 32 is not displaced outward, and thus it is not necessary to separate the attachment portion 2b of the body 2a very far from the periphery of the rotor 3. It is thus 16 possible to keep the height dimension down.

[Alternative embadiments] (a) In the abovernentioned embodiment, the second arm portion 32 was provided inclined such that it became further away from the rotational axis X as one moved from the base to the tip, but the form of the second a= portion is not Iiinited to the abovementioned embodiment In the embodiment shown in Figure 9, for example, the second arm portion 60 is formed approximately parallel to the rotational axis X and not only the tip but also the base are formed in a position which is further away from the rotational axis X and the base of the first arm portion 31.

In this case also, in the same way as mentioned above, the second bail support member attachment seat face 60b of the second arm portion 60 is further away from the rotational axis x than the fint bail support member attachment seat face 31b of the first arm portion 31. Therefore, the center of gravity of the second bail support member 43 is further way from the rotational axis X than the center of gravity of the first bail support member 40 including the line roller 41. Therefore, the same advantages as in the abovmentioned embodiment can be obtained.

(b) Yet another en-Lbodixnent of the second arm portion as shown in Figure 10. In this embodiment the second arm portion 61 is formed with a stepped shape, and the portion from the center to the rear is formed approximately symmetrically, about the rotational axis X, with the part of the first arm portion 31 which faces it across the rotational 17 a)ds X. On the other hand, ftom the cE!nter to the front it is located such that it is further away from the rotational axis X than the tip of the first arm porton 31 Even with such an embodiment, the second bail support member attachment seat face of the second arm portion 61 is further away from the rotational axis X than the first bail support member attachment seat face of the first arm portion 31, and theref6re the center of gravity of the second bail support member 43 is further from the rotational axis X than 'the center of gravity of the first bail support member 40 including the line roller 41. Thus the same advantages as in the previous embodi ment can be obtained.

(c) In the abovementioned embodiment both arm portions 31 and 32 are inclined, but as shown in Figure 11, both arm portions 31 and 32 may be formed parallel with the rotational axis X. In this case, it is preferable to locate a balancer 75 at the end of the rotor 3 on the reel body side. The balancer 75 is located to the side of the rotational axis X on which is located the first arm portion 31 on which the line roller is provided, and on the side on which the bail 45 is located duxing the line winding state. By means of the balance 75, the overall center of gravity of the first bail support member 40, the line roller 41 and the balancer 75 is displaced to the reel body side in comparison with the case in which the balance 75 is not provided, and location of balancers on opposite sides is simple.

(d) It is also possible to fit a balancer or weight member to the first 25arm portion 31 instead of the cover 31a.

(e) V et another embodiment is shown in Figure 12.

In this embodiment an attachment seat face is formed on the inside (rotational axis X side) of the tip of the first arm portion 65, and the first bail support member 40 is fitted to the attachment one seat face 65a with freedom to Pivot. However. the second arm portion 66 is locatedsymmetrical.ly to the first arm portion 65 with respect to the rotational axis X Further, an attachmint seat face 66a is formed an the outside of the tip of the second arm portion 66, and the second bail support member 43 is fitted to this attachment seat face with freedom to Pivot Elere, the distance R2 from the rotational axis X to the side face of the second bail support member 43 on the rotational axis side is longer than the distance R1 from the rotational axis X to the side face of the first bail support 4o on the rotational axis side. Thus the center of gravity of the second ball suppor t member 43 is further from the rotational axis X than the center of gravity of the first bail support member 40 including the line roller 41.

The advantages of the abovementoned embodiment can also be obtained in this case.

Yet another embodiment is shown in Figure 13.

In this embodiment the first bail support member 40 is fitted to the tip of the first arm portion 67 with freedom to swing, and further a second bail support member 69 is fitted to the tip of the second arm portion 68 with freedom to swing. Further, the center of swing of the second bail support member 69 is located further forward than the 19 center of swing of the first bail support member 40, and the axis of swing Y is not orthogonal to the rotational axis X Furthermore, a hollow of a given depth is provided directed from the base towards the tip in the second am portion 68.

In such 'In ernbOdirnent the overall center of gty including all Of the components on the second arm portion side is located further forward, and imbalance resulting from the first bail support member 40 including the line roller 41 is more readily suppressed.

[Advantages of the invention] AS outlined above, in a spirming reel according to the present invention the tip On the second arm portion side is fta-ther away from the mtational axis dun the facing tip of the first arm portiott Ort"wl- dch the line guiding portion is provided. It is thus possible to suppress imbalance during rotation without providing a balancer on the second alu portion side, or without altering the small size of the cam on the second arm portion side.

In the spinning reel according to another aspect of the present invention, the second ani portion is inclined such that it becomes further away frorn the rotational zods of the rotor as one moves towards the tip, and it is thus possible to position the center of gravity of the second arm portion side further forward, and it can approach the position of the overall center of gravity of the first arm portion side.

In a spinning reel according to another aspect of the present invention, the bases of the first and second arm portions are positioned approximately equidistant from the rotational axis of the rotor, and thus the size of the reel body can be reduced since it is possible for the reel attachment portion to be doser to the rotor.

In a spinning reel according to yet another aspect of the present invention, the first and second arm portions are displaced, with respect to the rotational axis of the rotor, to the side on which the bail is positioned in the line release state, and it is thus Possible to Suppress imbalance resulting from the bail, due to this displacement In a spinning reel according to yet another aspect of the present invention, the bases of the first and second arm portions are positioned m the side Mii which the bail ispositioned in the line winding state, and thus the overall center of gravity of the bases and the bail can be set on the reel body side (rear), and it is simple to provide balances on opposite sides in order to suppress imbalance.

In a spinning reel according to yet another aspect of the present invention, the overall center of gravity of Inernbers on the arm pardon side, the center of gravity of which is positioned further forward, is positioned on the reel body side, by means of a balance means, and it is thus simple to provide balancers on opposite sides in order to suppress imbalance.

In a spinning reel according to yet another aspect of the present invention, a balance mearLs emuLsts of a cover which is fitted to -the outside of the arm portion, and it is thus possible to sup"s imbalance using a simple construction without providing a special balancer.

In a spinning reel according to yet another aspect of the present invention, the second bail support member rear end and the second 21 arm portion are connected smoothly, and thus catching of the fishing line is reduced.

In a spinning reel according to yet another aspect of the present invention,, the center of swing of the second bail support member is positioned further forward than the center of swing of the first bail support member and it is thus simple to suppress imbalance resulting from the first bail support member and the like.

The foregoing description of the embodiments according to the present invention is provied for the purpose of illustration only. and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
