Description:
BACKGROUND OF THE INVENTION  
         [0001]    This invention relates to a fishing spinning reel which is capable of reversibly supporting a bail supporting member having a bail and a fishing line-guide portion onto a rotor rotating in association with a fishing line coiling operation of a handle under a fishing line-winding condition and under a fishing line-releasing condition.  
           [0002]    The fishing spinning reel has a structure including a rotor and a spool. The rotor is rotated and the spool is moved back and forth in association with winding and rotating operations of the handle. The rotor is provided with a pair of supporting arms rotating around the spool. In front of the pair of support arms, the bail support members are reversibly supported by a switching-spring, and one-sidebail support member is provided with a fishing line guide portion. These bail support members are attached with base portions of the bails for picking up the fishing line.  
           [0003]    According to the fishing spinning reel of the above mentioned structure, the bail (the bail support members) shits from the fishing line-winding position to the fishing line-releasing position by raising the bail, and under this condition, a fishing rod is forcibly brought down, so that a fishing tackle is thrown. Then, the fishing tackle lands on a water surface, if the bail (the bail support members) is returned (rotating the handle in the coiling direction, otherwise manually returning operation), the fishing line is picked up and moved to a fishing line guide portion and the operation is shifted to the fishing line-winding condition.  
           [0004]    In the series of operations, owing to force when bringing down the fishing rod to release the fishing tackle, or influence of unnecessary rotation of the handle, it might happen that the bail support members held at the fishing line-releasing position of the support arms return by error to the fishing line-winding position by unnecessary rotation of the rotor, and the fishing line is broken together with the fishing tackle.  
           [0005]    Therefore, as instruments for preventing the erroneous return caused by the unnecessary rotation of the rotor when releasing the fishing line, such fishing spinning reels incorporated with an erroneous return prevention apparatus have been proposed as disclosed in Japanese Utility Model Laid Open No. 50273/1981 (Known Example 1) or Japanese Patent Laid Open No. 69931/1999 (Known Example 2).  
           [0006]    Known Example 1 discloses a structure of preventing the rotor from unnecessary rotation by contacting a breaking member to a front part of a body, the breaking member being secured to a front end of a kick-lever rotating in company with the bail being released and reversed from the fishing line-winding condition to the releasing condition. Further, Known Example 2 discloses a structure of preventing the rotor from unnecessary rotation by contacting the front end of the kick-lever to a ring-like elastic member (O-ring) attached to the front part of the body, the kick-lever rotating in company with the bail being released and reversed from the fishing line-winding coiling condition to the releasing condition.  
           [0007]    However, in the art disclosed in Known Example 1, since biasing force of a spring when releasing and reversing the bail is served as a break holding force of the rotor, such serving amount makes heavy the returning and rotating operation of the rotor by rotating the handle from the fishing line-releasing condition to the coiling condition, so that the returning operation performance is worsened. At the same time, a bias holding state (a moderation holding force) is not stabilized in the fishing line-releasing position of the bail.  
           [0008]    In the art disclosed in Known Example 2, since the biasing force of a switching-spring is utilized to impart the breaking force to the rotor similarly to Known Example 1, the returning and rotating operation of the rotor by rotating the handle from the fishing line-releasing condition to the coiling condition is made heavy, so that the returning operation performance is worsened, and at the same time, a bias holding state (a moderation holding force) is not stabilized in the fishing line-releasing position of the bail. In addition, the ring-like elastic member (O-ring) attached in an extended state is easy to deteriorate, and sizes are easily made dispersed, so that the breaking performance and the endurance are worsened.  
         SUMMARY OF THE INVENTION  
         [0009]    The invention has been realized on the basis of the above mentioned problems, and it is accordingly an object of the invention to provide a fishing spinning reel which has a good returning operational performance from the fishing line-releasing condition to the fishing line-winding condition, a stable bias holding force (the moderation holding force) in the fishing line-releasing position of the bail, and an incorporation of the erroneous return prevention apparatus of good breaking performance and endurance.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0041]    First Embodiment  
         [0042]    [0042]FIG. 1 is a side view showing one embodiment of the fishing spinning reel according to the invention. At first, referring to FIG. 1, explanation will be made to a whole structure of the fishing spinning reel.  
         [0043]    The fishing spinning reel  1  comprises a reel main body  2  formed with a fishing rod attaching portion  2   a  for attaching to the fishing rod, a rotor  3  rotatably attached to the front part of the reel main body, a spool  5  movably back and forth synchronously with rotation of the rotor  3 , and a handle  6  rotatably supported by the reel main body  2  for rotating the rotor and moving back and forth the spool.  
         [0044]    The rotor  3  is formed with a pair of support arms  3   a , and at the respective front ends of the support arms  3   a , the bail support members  9  (hereinafter referred to as “support member”) to which the base parts of the bail  7  are attached are adapted to be held in the fishing line-winding position and the fishing line-releasing position. One base part of the bail  7  is attached to a fishing line guide portion  10  integrally formed to the support member  9 .  
         [0045]    With such a structure, when winding the handle  6 , the rotor  3  is rotated and driven, the spool  5  is moved back and forth, and the fishing line is evenly wound on the spool  5  via the fishing line guide portion  10 . The fishing line is released (casting the fishing tackle) by shifting the support member  9  (the bail  7 ) from the position of FIG. 1 to the fishing line-releasing position to make a state of getting out the fishing line from the fishing line guide portion  10  and bringing down the fishing rod.  
         [0046]    Next, explanation will be made, with reference to. FIGS.  2  to  9 , to structure and actuation of an erroneous return prevention apparatus for stabilizing the support arm  9  in the fishing line-releasing position when shifting the support member  9  for casting the fishing line. FIGS. 2 and 3 are views of an interior structure of the support arm of the rotor, showing the fishing line-winding position and the fishing line-releasing position, respectively. FIGS. 4 and 5 are views of a whole structure of the rotor and a partially cross sectional views of the support arm part, showing the fishing line-winding position and the fishing line-releasing position, respectively. FIGS. 6 and 7 are views enlarging the elementary parts of FIGS. 4 and 5. FIGS. 8 and 9 are plan views respectively along A-A line and B-B line of FIGS. 4 and 5.  
         [0047]    The erroneous return prevention apparatus  15  is arranged in one of the support arms  3   a  of the rotor  3 . In this embodiment, it is arranged within the support arm at the side furnished with the fishing line guide portion  10 .  
         [0048]    The support member  9  is rotatably supported within the support arm  3   a  by a pin  17 , and structured so that the support member  9  is shifted to the fishing line-releasing position and the fishing line-winding position by a later mentioned switching-spring. Around the pin  17  of the support member  9 , an arc-like oblong hole  9   a  is formed. When the support member  9  is rotated, the oblong hole  9   a  is guided by a convex  3   b  projected in the support arm  3   a.    
         [0049]    The support arm  3   a  is provided almost at a center with a rotatable holding portion  3   c . A bar like working member  20  is supported by the holding portion  3   c  and is rotatable as the holding portion  3   c  being a rotational axis. The bar like working member  20  in the center of the holding portion  3   c  is formed at one end side with a projection  21  being bent outside and held nearly a rotation supporting portion of the support member  9 . The other side of the working member  20  extends toward the reel main body. When the support member  9  shifts from the fishing line-winding position to the fishing line-releasing position, a front end  20   a  thereof is engaged with the reversing member as mentioned hereinafter. Between the holding portion  3   c  and the projection  21 , a coil shaped switching-spring  22  is arranged for shifting the support member  9  between the fishing line-winding position and the fishing line-releasing position.  
         [0050]    As shown in FIGS. 4 and 5, the reversing member  20  is rotatably supported via a screw  25  by a connection portion defined between a cylindrical part  3   d  and the support arm  3   a  of the rotor  3  so that a plane of the reversing member  20  is substantially orthogonal to the rotational axis of the rotor. At the side part of the reversing member  30 , an engaging projection  30   a  faces upward so that the reversing member  30  is positioned into an inside space of the support arm  3   a , and a front end  20   a  of the working member  20  is engaged with the engaging projection  30   a , the front end part  20   a  of the working member  20  being rotated in response to the reversing action of the support member  9  to the fishing line-releasing position (see FIGS. 2 and 3).  
         [0051]    Incidentally, the reversing member  30  is furnished with a kick portion  30   b , an elastic support plate  30   b ′ and a breaking member  30   c . The kick portion  30   b  moves toward the center side of the rotor  3  when being rotated around the screw  25 . The elastic support plate  30   b ′ is integrally and fixedly attached to the surface of the reversing member  30  and is furnished with an elastically deformable side wall part  30   b ″. The breaking member  30   c  is urged to the outer periphery of the ring shaped breaking portion  2   b  fixedly fitted to the front part of the reel main body  2 . In this case, the breaking member  30   c  is, as shown in FIG. 8, formed like a plate extending in a tangent direction of the ring shaped breaking portion  2   b  so as to hold the elastic side wall  30   b ″ of the elastic support plate  30   b ′. When the reversing member  30  is rotated, the breaking member  30   c  is elastically deformed at its distal via the elastic side wall  30   b ″ as shown in FIG. 9 and is urged to the outer periphery of the breaking portion  2   b.    
         [0052]    The breaking portion  2   b  may be formed directly at the front part of the reel main body  2 , but it is preferable to form the breaking portion  2   b  with another ring shaped member as shown in the illustrated embodiment, because the degree of freedom is increased without being restrained by a material of the reel main body  2  or a surface treatment. The breaking portion  2   b  is, if needed, performed with the surface treatment in response to a resin, Al-alloy, Cu-alloy, Mg-alloy, or metals such as stainless steels. The breaking member  30   c  is preferably formed with a rubber thread to be elastically deformed of itself, or others as a cork material of large frictional coefficient, and in case of being formed with an elastically deformable material, it may not be equipped at an elastically deformable part (the elastic side wall part).  
         [0053]    As to the breaking member  30   c , when the rotor  3  is rotated in the fishing line-winding direction (the arrow direction of FIGS. 8 and 9), the end portion opposite to the rotating direction contacts the breaking portion  2   b  under the elastically deformed condition, thereby make a good rotation of the rotor.  
         [0054]    On the other hand, at the front part of the reel main body  2 , when the rotor  3  is rotated in the fishing line-winding direction under a condition where the reversing member  30  is rotated and driven, a reversing projection  2   c  is projected toward the rotor side at a position where the kick part  30   b  can be contacted. The reversing projection  2   c  is formed with a taper for the reversing member  30  to smoothly move in semi-circle when the kick part  30   c  contacts.  
         [0055]    Next, explanation will be made to the actuation of the erroneous return prevention apparatus in the above mentioned structure.  
         [0056]    When the support member  9  rotates from the fishing line-winding position shown in FIG. 1 to the fishing line-releasing position, the oblong hole  9   a  rotates following the convex  3   b  as shown in FIGS. 2 and 3. According to this rotation, the working member  20  is rotated about the center of the holding portion  3   c , and its front end portion  20   a  is engaged with the engaging projection  30   a  of the reversing member  30 . The engaging projection  30   a  is pushed by the front end portion  20   a  of the working member  20 , whereby the reversing member  30  is rotated around the screw  25 .  
         [0057]    When the reversing member  30  rotates, the breaking member  30   c  provided therein is elastically deformed at its front end via the elastic side wall  30   b ″ as shown in FIGS. 7 and 9, and is urged to the outer periphery of the ring-like breaking portion  2   b  equipped at the front part of the reel main body. The rotor  3  is thereby regulated in rotation owing to frictional force between the breaking member  30   c  and the outer periphery of the breaking portion  2   b . Accordingly, when releasing the fishing line, the unnecessary rotation to the rotor  3  is avoided, and the erroneous return of the support member  9  to the fishing line-winding position accompanied with the rotation of the rotor is exactly prevented.  
         [0058]    Since the kick part  30   b  of the reversing member  30  enters toward the center of the rotor, when the handle is rotated after throwing the fishing tackle, the kick part  30   b  is kicked by the reversing projection  2   c  formed in the reel main body and returned to the position shown in FIG. 8. According to this action, the working member  20  is rotated from the state shown in FIG. 3 to the state shown in FIG. 2, and the support member  9  is returned to the fishing line-winding position at a point exceeding a dead point of the switching-spring  22 .  
         [0059]    According to the above mentioned erroneous return prevention apparatus, the reverse-holding force of the support member  9  to the fishing line-releasing position by the switching-spring  22  is independent, that is, not directly acting on the rotor breaking force. Since the rotation of the reversing member  30  is not positioned by the switching-spring, the returning operation from the fishing line-releasing condition to the fishing line-winding condition by the operation of the handle is smoothly carried out. In addition, as the structure gives the breaking force by urging the front end of the breaking member  30   c  to the outer periphery of the ring-like breaking portion  2   b  so that the front end of the breaking member  30   c  is elastically deformed, positional changes to the breaking portion  2   b  owing to production errors or time-passing changes are prevented, and the moderation holding force at the fishing line-releasing position of the support member  9  is stabilized so that the erroneous return preventing effect is exactly available. Furthermore, since the breaking member  30   c  is not structured to be ring-shaped, deterioration is less to occur and endurance is difficult to go down, and the breaking performance can be stably maintained for a long term.  
         [0060]    As far as the reversing member  30  is driven by such a member (part) not acted on by the direction holding force of the switching-spring  22  when the support member  9  is rotated to the fishing line-releasing position, various modifications are possible for the structure of the working member  20 . Further, as far as the breaking member  30   c  is structured to be urged to the outer periphery of the ring like breaking portion  2   b  when the support member  9  is reversed to rotate the reversing member  30 , various modifications are possible for shapes thereof.  
         [0061]    Specifically, for example, as modified in FIGS. 10 and 11, appropriate deformations are possible in that the breaking member  30   c ′ is formed to be somewhat thick, which is attached to the side of the elastic side wall  30   b ″ of the elastic support plate  30   b ′ of the reversing member  30 , and the inside of the front end of the breaking member  30   c ′ is formed to urge to the outer periphery of the breaking portion  2   b . According to these modifications, as the breaking member  30   c ′ is somewhat thick in the contacting direction, the breaking force is heightened and the breaking condition is made stable.  
         [0062]    Second Embodiment  
         [0063]    [0063]FIGS. 12 and 13 are views of a second embodiment of the invention showing the structure of the erroneous return prevention apparatus furnished to the fishing spinning reel. This embodiment shows the structure corresponding to that of FIGS. 8 and 9, and the same structural parts are given the same reference numerals.  
         [0064]    With respect to the reversing member  50  according to this embodiment, similarly to the reversing member  30  according to the first embodiment, the reversing member  50  is rotatably supported via a screw  55  by a connection formed between the cylindrical part of the rotor and the support arm, so that a plane of the reversing member  50  is substantially orthogonal to the rotation axis of the rotor. At the side part of the reversing member  50 , the engaging projection  50   a  faces upward so that the reversing member  50  is positioned into an inside space of the support arm of the rotor, and a front end  20   a  of the working member  20  engages the engaging projection  50   a , the front end  20   a  of the working member  20  being rotated in response to the reversing action of the support member  9  shown in FIG. 2 to the fishing line-releasing position.  
         [0065]    In the side surface of the spool side of the reversing member  50 , a projection  50   b  is formed and extends toward the side of the connection. A hole  3   h  is formed for receiving the projection under the connection. Between the reversing member  50  and the head of the screw  55 , a spring  57  is arranged to urge the reversing member  50  to the side of the connecting part.  
         [0066]    When the reversing member  50  is rotated by the working member  20  as shown in FIG. 3, the projection  50   b  is received in the hole  3   h  in the positional relation where the front end of the kick portion  50   c  of the reversing member  50  contacts the ring like breaking portion  2   b.    
         [0067]    That is, the reversing member  50  is switched between the breaking and non-breaking positions of the ring like breaking portion  2   b  by the projection  50   b , the hole  3   h  receiving it and the spring  57 .  
         [0068]    The breaking portion  2   b  is formed with the reversing projection  2   d  projecting in the diameter direction. When the handle is operated to rotate the rotor, the kick part  50   c  of the reversing member  50  is contacted to the breaking portion  2   b  so as to return the reversing member  50  to the non-breaking position shown in FIG. 12. Accordingly, as to the projection  50   b , the hole  3   h  receiving it and the spring  57 , when the kick part  50   c  is contacted to the reversing projection  2   d , the projection easily gets out from the hole  3   h.    
         [0069]    In the structure having the switching mechanism, the same working effect as in the above mentioned embodiment is obtained, and further, since it is unnecessary to furnish the breaking member in the reversing member, no problem occurs in deterioration of the breaking member. By the way, in this structure, the ring like breaking portion  2   b  is appropriately treated as roughening materials of resins or rubber threads of large frictional force in relation with the kick part  50   c , metal surfaces, or coating a paint to increase the frictional coefficient.  
         [0070]    According to the structure of the invention, such a fishing spinning reel may be obtained which has the good returning operational performance from the fishing line-releasing state to the fishing line-winding state, the stable bias holding force (the moderation holding force) at the fishing line-releasing position of the bail, and an incorporation of the erroneous return prevention apparatus of good braking performance and endurance.
