Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a braking device,
The present invention relates to a dual-bearing reel braking device for braking a spool of a dual-bearing reel having a reel body and a spool whose both ends are rotatably supported by the reel body.

[0002]

2. Description of the Related Art Generally, a dual bearing reel includes a reel body having a pair of side plates and a handle, and a spool rotatably supported by the reel body between the side plates. The handle is connected to the spool via a clutch. By rotating the handle while the clutch is on, the spool rotates to wind the fishing line. Further, when the clutch is turned off, the handle and the spool are disconnected from each other and the spool can be freely rotated. In this state, the fishing line is paid out from the spool by casting.

At the time of casting, the fishing line is paid out from the spool by the weight of the tackle attached to the tip thereof. When the speed at which the fishing line is fed out becomes higher than the rotational speed of the spool during the line feeding, a so-called backlash phenomenon occurs. When the backlash phenomenon occurs, the fishing lines are entangled with each other or the fishing line is caught between the spool and the reel unit.

In order to prevent the occurrence of this backlash phenomenon, a spool braking mechanism called a casting control mechanism is provided on both bearing reels. This braking mechanism includes a mechanical type and a magnet type. In the mechanical type, a rotary knob provided on the reel body facing one end of the spool shaft, a pressing member for pressing one end side of the spool shaft in response to the rotation of the rotary knob, and a spool being pressed And a receiving member that receives the other end of the shaft. In this mechanical braking mechanism, the pressing force of the spool shaft is changed by the amount of rotation of the rotary knob to adjust the braking force.

On the other hand, in the magnet type, a conductor member fixed to the spool shaft, a magnet provided so as to face the conductor member, a magnet holding member that holds the magnet and moves back and forth in the spool shaft direction, and a magnet. And a cap provided on the reel unit for moving the holding member forward and backward by turning. This magnet-type braking mechanism rotates a magnetic flux by rotating a conductive member to generate an eddy current according to the number of rotations, and applies a force in a direction opposite to the rotating direction to the conductive member according to Fleming's left-hand rule. It brakes. In this braking mechanism, by rotating the cap, the gap between the magnet and the conductive member is adjusted to change the magnetic flux density acting on the conductive member to adjust the braking force.

Since the magnet type braking mechanism applies a braking force according to the number of rotations of the spool, there is an advantage that the resistance is small when the number of rotations is low. However, it is difficult to generate a braking force that sharply reduces the rotation speed. Therefore, in the magnet type braking mechanism, the speed of the lure suddenly decreases due to skipping (an advanced technique of bouncing the lure on the water surface), etc., and when the fishing line loses tension, the spool continues to rotate and Rush is likely to occur. On the other hand, the mechanical braking mechanism provides a constant resistance regardless of the speed of the spool, so that the rotational speed of the spool is immediately reduced when the tension of the fishing line is reduced. However, when the braking force is increased, the rotation of the spool becomes heavy when the yarn is wound. Therefore, in a normal dual-bearing reel, casting control is often performed by using these two braking mechanisms together.

By braking the spool by such a braking mechanism, the rotation speed of the spool does not become excessively high and the backlash phenomenon can be prevented. The braking mechanism brakes the spool not only during normal casting but also during skipping.

[0008]

In the above braking mechanism, particularly the mechanical braking mechanism, when the braking force is increased as described above, the rotation of the spool becomes heavy at the time of winding the yarn. Therefore, the braking is applied only when the yarn is delivered, and the braking is released when the yarn is wound. However, in the above conventional braking device, since the braking force is adjusted by the rotary knob, there is a problem that it is difficult to grasp the braking state. Therefore, it is difficult to judge how much the braking force should be adjusted when the braking is reapplied after the braking is released at the time of winding the yarn. Also,
In some cases, the rotary knob must be rotated several times, so the braking force cannot be switched instantaneously.

Therefore, in order to make it easier to grasp the braking state, there is a rotary knob in which a dot-like mark is formed. However, since the rotary knob may rotate several times, even if a mark is formed on the rotary knob, it is still difficult to grasp the braking state only by the rotational position of the mark. An object of the present invention is to make it easier to grasp the braking state of the spool of the dual bearing reel and to be able to instantaneously switch the braking force.

[0010]

A braking device for a dual-bearing reel according to a first aspect of the present invention is a device for braking a spool of a dual-bearing reel having a reel body and a spool whose both ends are rotatably supported by the reel body. And a braking means and an operating lever. The braking means is means for braking the spool. The operation lever is provided on one side of the reel body so as to be swingable, and operates the braking means by swinging. In this braking device, when the operating lever is swung, the braking means operates to brake the spool.

Here, since the braking operation is performed by swinging the operation lever, the braking state of the spool can be freely adjusted by the swing position of the operation lever. Therefore, the braking state can be grasped from the swing position of the operation lever. Moreover, since the braking can be performed with the predetermined braking force simply by swinging the swing lever to the predetermined swing position, the braking force can be instantaneously switched.

A braking device for a dual bearing reel according to a second aspect of the invention is
In the device according to the invention 1, the operation lever is 30
The braking means is operated by swinging between 180 degrees and 180 degrees. In this case, since the swing angle is moderately large, the braking force can be finely adjusted. If the swing angle is less than 30 degrees, the braking force cannot be finely adjusted, and if the swing angle exceeds 180 degrees, the swing range becomes too wide and it is difficult to release the braking instantaneously.

A braking device for a dual-bearing reel according to a third aspect of the invention is
In the device according to the invention 1 or 2, the braking means is
It has a pressing member that presses one end side of the rotating shaft by swinging the operation lever, and a receiving member that receives the other end side of the pressed rotating shaft. In this case, by swinging the operation lever, the pressing member presses one end of the rotary shaft toward the other end, and the receiving member receives the other end. For this reason, both ends of the rotary shaft are clamped by the two members and clamped. Here, the spool can be reliably braked with a simple configuration.

A dual bearing reel braking device according to a fourth aspect of the present invention is
The apparatus according to a third aspect of the present invention further includes a rotary knob provided on the other side of the reel body for moving the receiving member in the axial direction of the rotary shaft to press the rotary shaft toward the one end side. In this case, since the receiving member moves in the axial direction when the rotary knob is rotated, a predetermined braking force can be applied by the rotary knob, and a larger braking force can be adjusted and applied by the operation lever. Therefore, it is possible to instantaneously switch between a predetermined braking force and a larger braking force instead of releasing the braking.

A dual bearing reel braking device according to a fifth aspect of the present invention is
In the device according to any one of the inventions 1 to 4, the dual-bearing reel includes a clutch mechanism for engaging and disengaging a rotational force applied to a spool, and a clutch operating lever for operating the clutch mechanism, wherein the operating lever is , Is arranged near the clutch operating lever. In this case, it is not necessary to move the hand much when performing the clutch operation and the braking operation.
Therefore, these operations can be performed without delay at the start of casting or the start of winding.

This braking force can be adjusted by positioning the tubular portion 55 in the spool shaft 16 direction by swinging the operation lever 54. Also,
This braking state can be instantly grasped from the swing position of the lever portion 56 of the operation lever 54.

Here, braking can be performed by swinging the operating lever 54, so that the braking state can be grasped instantly. Further, since the operation lever 54 is arranged in the vicinity of the thumb rest 17 for operating the clutch 29, the clutch operation and the braking operation can be performed without delay during winding or casting. Furthermore, since the braking state can be adjusted simply by swinging the operating lever 54, the braking state can be switched instantaneously.
