DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spinning reel, and more particularly to a spinning reel in which a rotor having a pair of opposed arm portions is rotatably supported on a reel body.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body, a rotor rotatably supported by the reel body, and a spool around which a fishing line is wound. The rotor includes a first arm portion and a second arm portion that are arranged to face each other with the rotation axis interposed therebetween, a swing arm that is swingably attached to a tip of each arm portion, and a swing arm. It has a veil that is provided and can assume a line releasing position and a line winding position.
Further, a line guide portion (usually constituted by a rotating member called a line roller) for guiding the fishing line is provided at the tip of one swing arm (arm cam). At the time of winding the fishing line with the spinning reel, the fishing line is guided to the line guide via the bail, and is wound around the spool from the line guide.

[0003] As described above, since the arm cam including the line roller is provided on the rotor of the spinning reel, imbalance occurs depending on the position where the member is disposed and the weight thereof. So, for example,
As disclosed in JP-A-80887 and JP-A-52-80888, there has been proposed an arrangement in which a balancer is arranged inside a rotor or the like.

[0004]

In the spinning reel having the above-mentioned conventional balancer, the weight is balanced when the spinning reel is viewed from the front in a plan view.
However, as shown in FIG. 8, when viewed spinning reel laterally, the center of gravity W _P of arm cam 8 that includes the line roller 10 located at a relatively forward of the rotor 4, while the center of gravity W _T of the balancer 16 rotor 4 is located at the rear end.
Thus, the center of gravity W of the arm cam 8 including the line roller is
There are in distance gap in the axial direction between the rotation locus of the center of gravity W _T of _P of rotational path and the balancer 16. Therefore, when a rotation operation is performed in this state, a centrifugal force acting on these centers of gravity W _P and W _T exerts a force for tilting the rotor with respect to the rotation axis X. As a result, for example, when the winding operation is performed at a high speed, the rotor vibrates, and it is difficult to perform a smooth winding operation.

[0005] In particular, recently, in order to reduce the load at the time of winding the fishing line, the line roller is configured to have a large diameter,
Alternatively, a configuration is used in which a mechanism for releasing the veil with one touch is provided on the arm cam. In the spinning reel having such a configuration, the aforementioned center of gravity W _P
Appear more forward of the rotor. Therefore, the force for inclining the rotor as described above increases, and the vibration during the rotation operation increases, making it difficult to perform a smooth winding operation.

In order to improve the imbalance during rotation, a position opposed to the unbalanced load resulting from the arm cam comprising the aforementioned line roller across the rotational axis of the rotor (the center of gravity W _P facing position) It is conceivable to provide a balancer. That is, the balancer 16 in FIG.
It may be provided at a position facing the center of gravity W _P. However, in the conventional general rotor, the unbalanced load may appear at a relatively front position of the rotor as described above, and at a position where no member constituting the rotor exists on the opposed arm side. Many. When an unbalanced load appears at such a position, it is difficult to dispose the balancer. For example, in the example of FIG. 8, a balancer must be arranged at the tip of the arm on which the swing arm 9 is mounted, but such arrangement of the balancer reduces the commercial value of the reel.

Further, since the bail 3 is provided between the arm cam 8 and the swing arm 9, a rotational imbalance occurs due to an unbalanced load caused by the bail 3. However, since the unbalanced load caused by the bail 3 is often located further forward than the center of gravity W _P, the balancer cannot be arranged to face the unbalanced load.

An object of the present invention is to improve the rotational balance of a rotor by disposing a balancer without impairing the commercial value of a reel.

[0009]

A spinning reel according to the present invention is mounted on a fishing rod, and comprises a reel body, a rotor, a spool, a first balance means, and a second balance means.
Balance means. The reel body has a handle and can be mounted on a fishing rod. The rotor is rotatably supported at the front of the reel body and is rotated by a handle. A first arm and a second arm arranged opposite to each other so as to sandwich the rotation shaft, and a first swing arm which is swingably attached to a tip of the first arm and has a thread guide at the tip. A second swing arm swingably attached to the tip of the second arm portion, and a thread release posture provided between the first swing arm and the second swing arm and swinging together with both swing arms. And a bale that can assume a line winding posture. The spool is disposed between the first arm and the second arm. The first balance means is formed so that the center of gravity is located on the first rotation plane of the rotor, and in accordance with the amount of imbalance of the rotor components in the first rotation plane. The second balance means is arranged such that the center of gravity is located on the second rotation plane of the rotor at a position different from the first rotation plane,
And it is formed according to the amount of imbalance of the rotor component on the second rotation plane.

[0010]

In the spinning reel according to the present invention, the technique of "two-plane balancing", that is, when the mass of the rotating body is distributed in the axial direction, no matter how the unbalance is distributed, the two planes are balanced. The technology that can correct the imbalance by using is applied to the spinning reel to correct the imbalance.

An imbalance during rotation due to the unbalance occurs due to the components of the rotor. The unbalance is caused by an unbalance amount in the first rotation plane and an unbalance amount in the second rotation plane. You can think separately. Therefore, the first balance means and the second balance means are formed according to the amount of unbalance in each rotation plane. in this way,
Instead of correcting the imbalance by providing a balancer on a single rotation plane, the imbalance is corrected in consideration of the imbalance on the two rotation planes, so that it is easy to configure the balance means. Therefore, it is easy to improve the rotational balance without impairing the commercial value of the reel.

Is disengaged from the concave-convex surface 5A formed inside, thereby generating a click sound.

In this spinning reel, in order to reduce imbalance during rotation mainly due to the arm cam 8 including the line roller 10 and the swing arm 9 and the bail 3, the first balance is provided before and after in the center of the rotation shaft. Means B1 and second balancing means B2 are formed. The first balance means B1 is formed in accordance with the unbalance amount on the rotation plane S (see FIG. 1) of the total unbalance amount of the rotor, and as shown in FIG. Part 4A1,
The position of 4A2 is deviated from the rotation axis X by a predetermined amount D. The center of gravity of the first balance means B1 is located on the rotation plane S.

The second balance means B2 is formed in accordance with the unbalance amount in the rotation plane T (see FIG. 2) of the total unbalance amount of the rotor. Are provided by two balancers 11 provided in the first section. The combined center of gravity of these two balancers 11 is located on the rotation plane T. Further, in this spinning reel, as shown in FIG. 4, a balancer C is provided on the handle 1 in order to further suppress the rotation of the rotor 4 during casting. That is, if the imbalance of the handle 1 is large, the handle 1 may rotate during casting. When the handle 1 rotates, the rotor 4 rotates accordingly. When the rotor 4 rotates, the bail 3 is switched from the line releasing position to the line winding position.

Therefore, in this embodiment, a balancer C is provided on the side facing the grip portion 1B so as to offset the weight of the arm portion 1A and the grip portion 1B of the handle 1. Thereby, the imbalance of the handle 1 with respect to the handle shaft is eliminated, and the rotation of the handle 1 during casting is prevented. [Other Embodiments] (a) In the above embodiment, the mounting positions of the pair of arms 4A1 and 4A2 are deviated in order to constitute the first balance means. As shown, it may be constituted by a balancer 11 _S arranged on a rotation plane S at the front part of the rotor 4.

Two balancers 11, 11 may be provided at a smaller arrangement angle α. In this case, if the weight of the balancer 11 on the outer peripheral side of the rotor 4 is set to a large value, this balancer 11
Increases the centrifugal force. Therefore, when a predetermined centrifugal force is required for the first balance means B1, the load on the balancer 11 inside the first arm portion 4A1 is reduced,
The weight and size of the balancer 11 can be reduced. For this reason, it becomes easy to arrange another member inside the first arm portion 4A1.

(C) In the above embodiment, the balance means is formed at two positions in the direction of the rotation axis of the rotor. However, the balance means may be provided at three or more positions.
