Description

[Detailed description of the invention] A. Purpose of the invention [Field of industrial application] The present invention relates to a bail arm reversing device for an outer spool type fishing spinning reel.

[Prior Art] Conventionally, in the above-mentioned bail arm reversing device, when the bail arm is pressed to release the lock at the line winding position, the bail arm is reversed from the line winding position to the line release position by the spring force and returned to that position. When winding the yarn, the bail arm is automatically reversed from the yarn release position to the yarn winding position by forward rotation of the rotor (rotation in the yarn winding direction), and the bail arm is manually wound. A device configured to allow the yarn to be thrown from the take-up position to the yarn release position without reversing the yarn is known, for example, from US Pat. No. 2,966,314.

However, in the above-mentioned device, the operating arm, fitting, connecting rod, etc. are provided outside the rotor along with the bail arm lever, so fishing lines tend to get tangled, and it is difficult to obtain a simple design in terms of appearance. There is a problem.

[Problems to be solved by the invention] Therefore, as a result of studies in view of the above-mentioned conventional problems, the present invention can be reversed to the yarn release position by simply pressing the bail arm, and can be automatically moved by rotating the rotor. This device is a further improvement on the device that automatically reverses the bail arm to the line winding position.The main mechanism is housed in the rotor, and the linkage to the bail arm lever is performed inside the rotor to prevent line entanglement. The purpose is to avoid this as much as possible, and to obtain a simple appearance similar to a conventional reel that does not have the above-mentioned functions while having the above-mentioned functions.

B. Structure of the invention [Means for solving the problems] In order to achieve the above-mentioned object, the present invention provides a gear transmission mechanism in the arm of the rotor for transmitting the rotation of the bail arm lever to the link mechanism, and A link mechanism includes a link mechanism constituted by a plurality of links capable of forming a dead center, and a driven gear engaged with a spring that imparts an elastic force in a direction to release the dead center of the link mechanism. and a cam for reversing and returning the bail arm fixed to the reel body for reversing and returning the bail arm from the yarn release position to the line winding position together with the rotor that rotates in conjunction with the rotation of the handle; A pin for contacting the cam and forming a dead center in the link mechanism is provided in the driven gear and housed in a recess in the rotor integral with the link mechanism.

[Function] By housing the gear transmission, which is complicated and easily entangled, in the recess of the rotor arm, and housing the link mechanism, dead center release means, and bail arm reversal/return means in the rotor recess 3a. Not only can the bail arm be reversed to the yarn release state by pressing the length with a finger, and the bail arm can be reversed and returned to the yarn winding state by rotating the handle. It does not stick, and has a simple appearance that maintains the form of the conventional outskirt type spinning reel.

[Embodiment] An embodiment of the present invention will be described below in detail based on the drawings. As shown in FIGS. 1 to 5, a reel body 1 is rotatably mounted on a tube shaft 2. The rotor 3 is provided with arms 4 and 5 symmetrically protruding forward, and a bail arm 6 is attached to the ends of the arms 4 and 5, and a bail arm lever 7 is fixed at both ends. A bail arm cam 8 is pivotally connected by a step screw 9 or the like so that it can be rotated between a yarn winding position a shown in FIG. 1 and a yarn release position b shown in FIG. 4.

Here, a torsion spring (not shown) is interposed in the bail arm cam 8, and by applying rotational force to a predetermined position by the spring, the bail arm 6 is resiliently rotated from the line winding position a. Thus, the yarn is held at the yarn release position b.

A link mechanism 10 is located in a recess 3a facing the reel body 1 around the bearing portion of the rotor 3.
However, the bail arm lever 7 and the gear transmission mechanism 1
1, and a driven gear 12 with a pin 13 attached thereto so as to be rotationally interlocked with the link mechanism 10 is rotatably supported, and a spring 14 is interposed in the driven gear 12. A spring force is applied in the direction shown by the arrow c in FIG. The bail arm reversing cam 15 is arranged to interfere with the bail arm reversing cam 15 fixedly installed on the reel main body 1 side of the rotor 3 by being pivotally supported by a stepped screw 16 or the like.

As clearly shown in FIG. 3, the gear transmission mechanism 11 includes a bail arm lever gear 11a carved around the shaft of the bail arm lever 7, and an idle gear 11b meshing with the bail arm lever gear 11a. , a drive gear 11c that meshes with the idle gear 11b, a connection gear 11d coaxial with the drive gear 11c, and a connection gear 11c that is coaxial with the drive gear 11c.
d and a link gear 11e that meshes with the link gear 11e.

That is, the bail arm lever gear 11a
, idle gear 11b, and drive gear 11c
The cover plate 4a is rotatable by the step screw 9, the boss 17 of the arm 4, and the connecting shaft 18 penetrating the base end of the arm 4, and is fixed to the arm 4 by the screw 19. By being covered, the coupling gear 11d is housed inside the arm 4 and is not exposed to the outside.On the other hand, the coupling gear 11d is fixed to the inner end of the coupling shaft 18 protruding into the recess 3a of the rotor 3, and The link gear 11e is pivotally supported by the annular wall 3b of the rotor 3 with a step screw 20, and is housed in the recess 3a.

The link mechanism 10 also includes a first link gear 11e, which is pivotally connected to the rotor 2 with step screws 20, as shown in FIGS. 2 and 5.
a second link 10b whose one end is pivotally connected to the first link 10a with a pin 21;
The other end of the second link 10b and a third link 10c pivotally connected by a pin 22 form a dead center, and the third link 10c is integrally provided with a gear 10d, Step screw 23 on the rotor 3 above
It is rotatably pivoted at. The link mechanism 10 and the driven gear 12 are arranged such that the driven gear 12 is the gear 10 of the third link 10c.
d and thereby interlocked with each other, the spring force of the spring 14 interposed in the driven gear 12 is elastically biased against the link mechanism 10.

In FIGS. 1, 3, and 4, reference numeral 24 denotes a spool for winding fishing line, which is fixed to a sliding shaft 25 inserted through the tube shaft 2, and is attached to a handle 26.
The rotor 3 slides back and forth in the front-back direction by the rotation operation of the rotor 3, and at this time the rotor 3 rotates to evenly wind the fishing line (not shown) that is hung on the bail arm 6, which is different from the conventional method. Since it is similar to a spinning reel, detailed explanation will be omitted. In the above configuration, the bail arm 6 is held at the thread winding position a shown in FIG. 1 because the link mechanism is in the state shown in FIG. 2. The repulsive force of a torsion spring (not shown) is applied to the cam 8 as a motive force for moving the yarn from the yarn winding position a shown in FIG. 1 to the yarn release position b shown in FIG. The force is transmitted to the bail arm lever 7 through the bail arm 6 integrally attached to the lever 8, and further transmitted as a force in the direction of arrow g to the first link 10a via the gear transmission mechanism 11, and then to the second link 10b. It is transmitted as a pressing force in the direction of arrow f,
This is transmitted as a force that rotates the third link 10c in the direction opposite to the arrow e, and is further transmitted as a rotational force in the direction opposite to the arrow d to the driven gear 12 meshing with the gear 10d. At this time, the ratio of the strength of the elastic force of the torsion spring to the elastic force of the spring 14 is approximately 10 to 20:1, and the elastic force of the torsion spring is much larger, so the pin 13 of the driven gear 12 is connected to the rotor 3 (not shown). Since the pin 13 comes into contact with the stopper of the pin 13 and stops, the state shown in FIG. 2 is maintained, and as a result, the state of the line winding position a shown in FIG. 1 is maintained. Since the state shown in FIG. 2 constitutes a situation where the link mechanism is at its dead center, the bail arm 6 is held at position a without being reversed, and thread winding is executed. Ru.

When the bail arm 6 is in the state shown in FIG. 1 in the line winding position a, when the bail arm 6 is slightly pressed to the right in the figure with a finger, the bail arm lever 7 and the bail arm cam 8 move counterclockwise in the figure. This rotational force is applied to the idle gear 11b that engages with the bail arm lever 7, the drive gear 11C, the connecting shaft 18, and the connecting gear 11d.
Since the first link 10a, which rotates integrally with the link gear 11e, is slightly rotated in the opposite direction of the arrow g, the second link 10b is pulled in the opposite direction of the arrow f. When this tensile force is applied until the third link 10c is rotated in the direction of the arrow e and the pin 21, the second link 10b, the third link 10c, and the step screw 23 are aligned, the link The conditions for releasing the dead center situation configured by the mechanism have been met, and the situation is just before the dead center is released. Moreover, since the elastic force of the torsion spring is canceled by the rotational force of pressing the bail arm 6 counterclockwise with a finger, the elastic force of the spring 14 acts on the driven gear 12 in the direction of arrow d, and the driven gear 12 By further rotating the third link 10c, which rotates in the same direction as the gear 10d meshing with the gear 10d, the dead center situation is completely overcome, and the force of the fingers pressing counterclockwise on the bail arm 6 is released. At the same time, the elastic force of the torsion spring acts on the transmission system including the gear transmission mechanism and the link mechanism, and the bail arm 6 moves to the state shown in FIG.
move in an instant. In other words, bail arm 6
without reversing it with your finger to the thread release position b.
The bail arm 6 can be reversed to the yarn release position b simply by pressing the bail arm 6 in the opposite direction to the yarn release position and releasing the hold at the yarn winding position a.

When the bail arm 6 reaches the yarn release position b as described above, the driven gear 12 is rotated in the direction of the arrow d shown in the figure via the gear transmission mechanism 11 and the link mechanism 10, so that the pin 13 is moved to the second position b. From the position shown in the figure to the position shown in FIG. 5, it becomes a position where it interferes with the bail arm reversing cam 15.

Next, if you want to wind the fishing line, use the handle 2.
When the rotor 3 is rotated forward (in the winding direction), that is, clockwise in FIG.
a and is pressed in the opposite direction of arrow c, the driven gear 12 is rotated in the opposite direction of arrow d, and due to the rotational force, the link mechanism 10 is operated beyond the dead center to the state shown in FIG. Operation is gear transmission mechanism 1
1 to the bail arm lever 7, the bail arm 6 is rotated counterclockwise in FIG. 4 against the elastic force of the torsion spring, and as shown in FIGS. The line is reversed and returned to the line winding position a.

[Effect of the invention] As explained above, since the bail arm reversing device of the fishing spinning reel according to the present invention is constructed, the bail arm 6 is pushed from the line winding position a in the opposite direction to the line release position. By simply turning the handle 26, the bail arm 6 is reversed from the yarn winding position a to the yarn discharging position b, and by rotating the handle 26, the bail arm 6 is automatically reversed and returned from the yarn discharging position b to the yarn winding position a. In the bail arm reversing device, the main mechanisms of the device, that is, the gear transmission mechanism 11, the link mechanism 10, the driven gear 12, and the bail arm reversing cam 15 are all housed within the arm 4 and rotor 3 and do not protrude to the outside. Because of this structure, in a spinning reel equipped with this type of device, there are almost no elements for the fishing line to hang or get tangled, so line entanglement can be avoided as much as possible, improving the usability of this type of reel. At the same time, the structural members do not protrude to the outside,
Not only does it provide a simple design in terms of appearance, but it also has the effect of preventing breakdowns due to damage caused by structural members colliding with other objects during use or transportation.
