Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a double-bearing reel, and more specifically, to a double-bearing reel in which a spool shaft having a spool is supported in a freely rotatable manner via a pair of bearings. .

(Prior Art) Generally, a double bearing reel has a clutch, and when the clutch is engaged, the rotation of the handle shaft is transmitted to the spool shaft to wind the fishing line onto the spool, and when the clutch is disengaged, the fishing line is wound onto the spool. The spool shaft can rotate freely, and the casting operation is similar to casting a fishing line.

By the way, during casting, the fishing line wound around the spool is pulled out by the weight of the device attached to the tip of the fishing line, but the free rotation of the spool becomes faster than the pulling out speed of the fishing line, resulting in what is called backlash. As a result of this breakage, the fishing line becomes entangled or gets caught between the spool and the reel body, and for this reason, a brake is generally provided.

Further, as the brake, a centrifugal brake using a brake shoe is generally used. According to this centrifugal brake, since braking is performed by bringing the brake shoe into sliding contact with a brake drum, wear of the brake shoe is reduced. There was a problem that the braking force changed due to various reasons.

However, in order to solve the above-mentioned problem, a magnetic brake is used which is equipped with a magnet and an electric conductor facing the magnet, and one of the magnet and the electric conductor in this magnetic brake is made to rotate together with the spool. , the other is fixed to the reel body, and one rotation rotates the magnetic speed to generate an eddy current, and according to Fleming's left hand rule, a force is applied to the rotating member in the opposite direction to the rotating direction to brake the spool. A double-bearing reel with a unique structure was proposed.

(Problem to be solved by the invention) Since there is no contact part with this method, it is possible to solve the problem of the braking force changing due to wear of the braking member.
Moreover, although the braking force can be increased or decreased in proportion to the spool rotational speed, the rate of change in the braking force cannot be adjusted with respect to the spool rotational speed, so it is not possible to adjust the braking force in response to changes in the spool rotational speed. It cannot be done. That is, if the braking force of the magnetic brake is set larger than the spool rotational speed at which buck crash occurs, buck crash will be less likely to occur, but at the beginning of casting, an even greater braking force will act on the spool. The casting distance of the fishing line becomes shorter, and if the braking force is set to the minimum value for the spool rotational speed at the initial stage of casting, the casting distance of the fishing line can be increased, but there is a problem in that crashes are more likely to occur.

Therefore, this invention was devised in view of the above problems, and the purpose is to increase the throwing distance of the fishing line while also
To provide a double-bearing reel that can prevent crashes, accurately adjust braking force, and easily operate an adjusting body with the natural movement of the thumb of the hand gripping a fishing rod.

(Means for solving the problem) The basic idea of this invention is to be able to adjust the braking force that increases or decreases in response to the rotational speed of the spool, and the spool can be freely rotated on the reel body. A double-bearing reel is provided with a magnetic brake that supports the electric conductor and that includes a magnetic holder having a magnet and an electrical conductor opposing the magnet, the magnetic holder and the electric conductor being connected to each other with respect to the other. The magnet is movable in the radial direction of the spool, and the magnet is disposed on one side in the moving direction of the movable member, and a biasing means is provided for biasing the movable member so that the braking force is minimized or maximized. , an adjusting body that has an operating part that can be operated with the thumb of a hand holding a fishing rod to which the reel body is attached, and that adjusts the braking force by moving the movable side member in a direction opposed to the biasing means; The adjusting body is rotatably supported on the reel body via an axis parallel to the center of rotation of the adjusting body, and the adjusting body is provided with an interlocking part that links the operation of the operating part to the movable side member, and the adjusting body is controlled by the operation of the adjusting body. It is characterized in that the adjustment of the power is canceled by releasing the operation of the adjustment body.

(Function) By operating the adjustment body, one of the magnetic holder and the electrical conductor can be moved in the radial direction of the spool, and the braking force can be adjusted from the minimum to the maximum.
The rotational resistance of the spool at the initial stage of casting can be minimized, the casting distance of the fishing line can be increased, and crashing can be prevented. In addition, the movable side member that moves in the radial direction can be minimized by the biasing force. Or, since it is biased in the direction where it is maximum, when adjusting the braking force, the braking force can be adjusted while keeping the distance between the magnet and the conductor at a constant distance, so the braking force can be adjusted accurately. Since the adjusting body is rotatably supported through an axis parallel to the center of rotation of the spool, the thumb of the hand that grips the fishing rod is extended and brought into contact with the operating part of the adjusting body, and the thumb is bent in the natural direction. By operating the movable member in the radial direction of the spool, the braking force can be adjusted, and the operability for adjusting the braking force is good and can be easily operated.

A magnetic brake 5 is provided with an electrical conductor 51 facing 0, and one of the magnetic holder 52 and the conductor 51 in the brake 5 is biased with respect to the other so that the braking force is minimized or maximized. An adjusting body 55 is provided, which has a biasing means to do so, and an operating part 55b that adjusts the braking force by operating in a direction opposite to the biasing means, and the braking force by operating the operating part 55b in the adjusting body 55 is provided. The configuration is such that the adjustment is canceled by releasing the operation of the operation section 55b.

However, in the drawing, the magnetic holder 52 is movable in the radial direction relative to the conductor 512, and a pair of springs 54, 54 are used as the biasing means.
54 connects the magnetic holder 52 to the conductor 5.

It is installed concentrically with the

The magnet holder 52 is made of a non-magnetic material, and has a holding portion 52a for the magnet 50 on the outer periphery of one side in the radial direction, and an elliptical shaft hole 52b in the center, as shown in FIG. It is formed into a shape. The magnet 50 is held in the holding portion 52a so as to face the inner circumferential surface of the conductor 51, and the elongated shaft hole 52b is attached to the support tube 21 provided in the center of the bearing housing 21.
It is supported on the outer periphery of a so as to be movable in the radial direction with respect to the support tube 21a.

Further, a spring 54 constituting the biasing means,

Further, although it is preferable that the operating section of this adjustment body be disposed between the first and second side frames 1 and 2, it may be disposed on the second side frame 2 side or on the first side frame 1 side. However, the location thereof is not particularly limited.

In addition to using the spring 54 as a biasing means for biasing one of the magnetic holder 52 and the conductor 51 with respect to the other so that the braking force is minimized or maximized, the attractive force due to the magnetic force of the magnet 50 may be used. You can.

However, one of the magnet holder and the conductor is movable relative to the other in the radial direction of the spool, and the magnet is disposed on one side of the moving direction of the movable member, and the movable member is moved by a braking force. Since a biasing means for biasing the force to the minimum or maximum is provided and the movable member is moved in the radial direction against the biasing means by operating the adjustment body, the braking force can be minimized at once. can be adjusted to a maximum from
The rotational resistance of the spool at the beginning of casting can be minimized, and the throwing distance of the fishing line can be increased while preventing crashes.

Moreover, since the movable member that is moved in the radial direction is biased by the biasing means in the direction where the braking force is minimized or maximized, when adjusting the braking force, the distance between the magnet and the conductor can be maintained at a constant distance. Since the braking force can be adjusted, the braking force can be adjusted accurately.In addition, an adjusting body having an operation part that can be operated with the thumb of the hand that grips the fishing rod to which the reel body is attached is attached to the spool. Since it is rotatably supported via an axis parallel to the center of rotation, the thumb of the hand that grips the fishing rod is extended and brought into contact with the operating portion of the adjustment body, and the thumb is moved in a natural bending direction to make the rod movable. The braking force can be adjusted by moving the side member in the radial direction of the spool, and the braking force adjustment is easy to operate.
