1. Field of the Invention
This invention generally relates to a rotor for a spinning reel. More specifically, the present invention relates to a rotor for a spinning reel which is rotatively mounted to a reel unit and which guides and winds fishing line around a spool.
2. Background Information
Spinning reels generally have a reel unit that is mounted to a fishing rod, a rotor rotatively mounted to the reel unit that serves to guide fishing line, and a spool onto which fishing line that has been guided by the rotor is wound. The rotor has a rotor unit, and a bail arm that is pivotally mounted to the rotor unit. The rotor unit has a cylindrical portion that is rotatively mounted to the reel unit, and first and second rotor arms that are disposed opposite one another and extend outward from the rear end portion of the cylindrical portion.
The bail arm guides the fishing line to the spool, and has a first bail support member pivotably mounted to the tip of the first rotor arm portion, a second bail support member pivotably mounted to the tip of the second rotor arm portion, a line roller rotatively mounted to the tip of the first bail support member, and a bail made of a piece of wire that links the line roller and the second bail support member. The first rotor arm is provided with a bail tripping device, which maintains the bail arm in the line-winding posture and the line-releasing posture and returns the bail arm from the line-releasing posture to the line-winding posture in response to the rotation of the rotor in the line-winding direction.
This conventional bail-tripping device has a toggle spring that is mounted to the rotor and whose tip is engaged with the bail arm near the pivot center of the bail arm, a moving member whose tip is engaged with the bail arm near the pivot center of the bail arm and whose base moves forward and backward with respect to the reel unit, and a switching projection provided on the reel unit such that the switching projection comes into contact with the moving member. The toggle spring toggles and urges the bail arm between two postures, and maintains the bail arm in the two postures. The toggle spring and the moving member are both accommodated in an internal space provided in the first rotor arm. Example of such structure is shown in Japanese patent application publication H10-4839.
In the aforementioned conventional structure, the toggle spring and the moving member of the bail tripping device are both accommodated in the internal space of the first bail arm. Because of this, it is difficult to attach an interchangeable bail tripping device, since the shape of the internal space in the first rotor arm will differ depending upon the size of the rotor used with a reel.
In view of the above, there exists a need for a rotor which overcomes the above mentioned problems in the prior art. This invention addresses this need in the prior art as well as other needs, which will become apparent to those skilled in the art from this disclosure.
An object of the present invention is to make the bail tripping device in a rotor of a spinning reel that is interchangeable regardless of the size of the rotor.
A rotor of a spinning reel according to a first aspect of the present invention is a rotor of a spinning reel that has a reel unit and a spool. The rotor is rotatively mounted to the reel unit and guides fishing line around the spool. The rotor includes a rotor unit having a cylindrical portion that is rotatively mounted to the reel unit and a pair of rotor arms that each extend forward from opposing positions on an outer peripheral surface of a lower end portion of the cylindrical portion and are spaced apart from the cylindrical portion, a bail arm that is mounted to tips of the pair of rotor arms so as to be pivotable between a line-winding posture and a line-releasing posture, a mounting member that is detachably installed on one of the pair of rotor arms, and a bail tripping device of the spinning reel that is provided in the mounting member and which returns the bail arm to the line-winding posture from the line-releasing posture in response to the rotation of the rotor unit in the line-winding direction.
In this rotor, the mounting member is detachably installed on one the rotor arms, and the bail tripping mechanism is mounted on the mounting member. Here, by attaching the bail tripping device in advance on the mounting member and forming a bail tripping unit, a mounting member along with a bail tripping device that is attached to the mounting member as a unit can be installed on reels whose rotors are of different sizes.
A rotor according to a second aspect of the present invention is the rotor of the first aspect, in which the mounting member is arranged on the outer peripheral side of one of the pair of rotor arms. In this situation, when the bail arm is, for example, mounted on an outer peripheral side of the rotor arm, the mounting member can be easily installed onto the rotor arm.
A rotor according to a third aspect of the present invention is the rotor of the first aspect, in which the mounting member is arranged on the inner peripheral side of one of the pair of rotor arms. In this situation, when the bail arm is, for example, mounted on an inner peripheral side of the rotor arms, the mounting member will be installed from the inner peripheral side of the bail arm. Thus, the design of the spinning reel will improve because it will be difficult for the mounting member to be exposed on the outer peripheral sides of the rotor arms.
The rotor according to a fourth aspect of the present invention is the rotor of any of the first to third aspects of the present invention, in which the cylindrical portion has a large diameter portion and a tubular portion that is detachably arranged on a front end portion of the large diameter portion. In this situation, the tubular portion can, for example, be formed from a material that is different from the material that forms the large diameter portion. In particular, when the mounting member is mounted on an inner peripheral side of the rotor arm, the mounting member is easily detached from the rotor arm by removing the tubular portion.
A rotor according to a fifth aspect of the present invention is the rotor of any of the first to fourth aspects of the invention, in which the bail tripping device has a moving member, a toggle spring mechanism, and a switching portion. The tip portion of the moving member is engaged with the bail arm. The base portion of the moving member is detachably engaged with the mounting member such that, in response to pivoting of the bail arm, the base portion of the moving member is moveable at least forward and backward between a first position which corresponds to the line-winding posture, and a second position which corresponds to the line-releasing posture and is closer to the reel unit than the first position. The toggle spring mechanism has a tip portion that is rotatively engaged with the bail arm at a position that is different from the position at which the moving member is engaged with the bail arm. The toggle spring mechanism toggles and biases the bail arm into both the line-winding posture and the line-releasing posture, and the direction in which the bail arm is biased changes in response to pivoting of the bail arm. The switching portion is arranged on a front portion of the reel unit. When the rotor arm rotates in the line-winding direction, the switching portion will come into contact with the base portion of the moving member that is in the second position to move the moving member toward the first position.
In this bail tripping device, when the bail arm flips from the line-winding posture to the line-releasing posture, the base portion of the moving member moves into the second position. As this occurs, the toggle spring mechanism is compressed up to the dead point for a period of time, and then elongates and urges the bail arm into the line-releasing posture. When disposed in the line-releasing posture, the bail arm is prevented from returning to the line-winding posture. As a result, when in the line-releasing posture, it will be difficult for the bail arm to flip back toward the line-winding posture even during casting. In this state, when the rotor rotates in the line-winding direction, the base portion of the moving member in the second position will come into contact with the switching portion, which presses the moving member toward the first position and presses the bail arm into the line-winding posture. Then, when the toggle spring mechanism exceeds the dead point, the toggle spring mechanism elongates and presses the bail arm into the line-winding posture, and the bail arm is pressed by the switching portion until the moving member reaches the projecting end. As a result, the bail arm is no longer restrained, and is tripped into and maintained in the line-releasing posture. Here, the bail arm can be flipped by a simple structure.
These and other objects, features, aspects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description, which, taken in conjunction with the annexed drawings, discloses a preferred embodiment of the present invention.
Referring now to the attached drawings which form a part of this original disclosure:
Selected embodiments of the present invention will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following description of the embodiments of the present invention is provided for illustration only, and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.
Overall Configuration and Configuration of Reel Unit
As shown in
The reel unit 2 primarily includes a body member 2a for supporting the rotor 3 and the spool 4, and a lid member 2b detachably screwed to the body member 2a.
The body member 2a is, for example, made of a polyamide-based synthetic resin reinforced by glass fibers, and is produced by injection molding. The body member 2a has an aperture 25, and a mechanism accommodating space 26 is formed in the interior of the body member 2a. The mechanism accommodating space 26 is provided with a rotor drive mechanism 5 for rotating the rotor 3, an oscillating mechanism 6 for moving the spool 4 back and forth to uniformly wind the fishing line, and a power transmission mechanism (not shown in the figures) for transmitting the rotation of the handle 1 to the oscillating mechanism 6. An approximately circular rotation support portion 27 for rotatively supporting the rotor is formed on the front of the body member 2a.
The lid member 2b is, for example, made of an aluminum alloy, and is, for example, produced by die casting. As shown in

Since the bail tripping mechanism 48 is a well known component in the art, its structures will not be discussed or illustrated in further detail herein.
In addition, as shown in
As shown in
Configuration of the Spool
The spool 4 is disposed between the first rotor arm 31 and the second rotor arm 32 of the rotor 3, and is fixedly coupled to the tip of the spool shaft 15 via a drag mechanism 60. The spool 4 is a member made of, for example, an aluminum alloy, and includes a bobbin trunk portion 4a onto the outer periphery of which fishing line is wound, a skirt portion 4b integrally formed with the rear of the bobbin trunk portion 4a, and a front flange portion 4c fixedly attached to the front of the bobbin trunk portion 4a. The bobbin trunk portion 4a is a cylindrical member that extends to the outer peripheral sides of the cylindrical portion 30 of the rotor 3. Since the drag mechanism 60 is a well known component in the art, its structures will not be discussed or illustrated in detail herein.
Configuration of the Rotor Drive Mechanism
As shown in
Configuration of the Oscillating Mechanism
The oscillating mechanism 6 reciprocates the spool 4 forward and backward via the spool shaft 15 in cooperation with the rotation of the handle 1. The rotation of the handle 1 is transmitted to the oscillating mechanism 6 via a power transmission mechanism, which transmits rotation of the handle 1 to the oscillating mechanism 6 through the main gear 11, the pinion gear 12, and a driven gear 23. As shown in
Operation and Function of the Reel
To cast with this spinning reel, the bail arm 44 is pushed over from the line-winding posture to the line-releasing posture. Then, the fishing rod is swung and the tackle is cast out. When this occurs, fishing line is released in a helical fashion from the front of the spool 4.
When the fishing line is to be retrieved, the bail arm 44 is pushed over into the line-winding posture. This occurs automatically by the function of the bail tripping mechanism 48 when the handle 1 is rotated in the line-winding direction. When the handle 1 is rotated in the line-winding direction, the rotational force is transmitted to the pinion gear 12 via the main gear shaft 10 and the main gear 11. The rotational force transmitted to the pinion gear 12 is transmitted to the rotor 3 via the front portion 12a of the pinion gear 12, and the rotor 3 is rotated in the line-winding direction.
On the other hand, the threaded shaft 21 rotates through the driven gear 23, which meshes with the pinion gear 12 via the power transmission mechanism. Then, the slider 22 that meshes with the threaded shaft 21 is reciprocated forward and backward by the rotation of the threaded shaft 21. The fishing line guided onto the spool 4 by the bail arm 44 is wound onto the bobbin trunk portion 4a of the spool 4, and the fishing line is wound onto the spool 4.
In this rotor 3, the mounting member 49 is detachably installed in the first rotor arm 31, and the bail tripping mechanism 48 is mounted on the mounting member 49. Here, by attaching the bail tripping device 48 in advance in the mounting member 49 and unitizing the bail tripping device 48, the mounting member 49 having the unitized common bail tripping device 48 can be attached to reels whose rotors 3 are of different sizes.
(a) The foregoing embodiment was described using a front-drag type spinning reel as an illustrative example. However, the present invention can also be applied to the rotor of rear-drag type spinning reels and lever brake type spinning reels.
(b) In the foregoing embodiment, the tubular member 30a was detachably arranged on the large diameter portion 30b. However, the tubular member 30a and the large diameter portion 30b may be arranged such that they form a unitary integral member.
(c) In the foregoing embodiment, the mounting member 49 was installed on the outer peripheral side of the first rotor arm 31. However, the mounting member 49 may be configured so as to be installed on the inner peripheral side of the first rotor arm 31.
According to the present invention, because a mounting member in which a bail tripping device is mounted is detachably installed on one side of a rotor arm of a rotor of a spinning reel, the bail tripping device can be standardized and attached to a rotor arm regardless of the size of the rotor.
