Description

[Detailed Description of the Invention] The present invention relates to a double-shaft reel, and more particularly, to a double-shaft reel in which a spool shaft having a spool in the reel body is freely rotatably supported via a pair of bearings.

Generally, a double-shaft 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 spool shaft can freely rotate. 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. This causes the fishing line to become tangled or get 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 the brake drum, friction of the brake shoe, etc. There was a problem that the braking force changed due to the change in the braking force, and there was also a problem that the braking force could not be adjusted from the outside.

Therefore, in order to solve the above problems, a magnet and a metal conductor are used, one of which rotates together with the spool, the other is fixed to the reel body, and the magnetic flux is rotated by the rotation of one. to generate eddy current,
According to Fleming's left-hand rule, the spool is braked by applying a force in the opposite direction to the rotating direction of the rotating member, and the stationary member is applied in the axial direction of the spool shaft with respect to the reel body. A model was proposed in which the braking force could be adjusted by external operation.

According to this method, since there is no contact part, it is possible to solve the problem of the braking force changing due to wear of the braking member, and the braking force can be easily adjusted by external operation. is supported on the reel body and is movable in the axial direction of the spool shaft. Therefore, the braking force cannot be adjusted linearly, and the structure for maintaining the adjusted position due to the movement becomes complicated and costs increase. There was a serious problem.

The present invention was devised in view of the above-mentioned problems.The purpose is to have a simple structure, to be able to linearly adjust the braking force, and to have a mechanism for maintaining this adjustment position that is small and does not take up much space. The object of the present invention is to provide a double-shaft reel that can be incorporated into a reel.

That is, the present invention provides a spool or a spool shaft.

The magnet 51 of the magnetic ring 53 is attached to the inner peripheral surface of the magnetic ring 53 so as to be operable.
A plurality of protrusions 53b are provided that protrude toward the outer circumferential surface of the magnet ring 52 from opposing positions, so that a magnetic field is generated between these protrusions 53b and the magnet 51.

In the above configuration, four magnets 51 and four protrusions 53b are provided each with a phase difference of 90 degrees, and the magnets 51 are provided with N and S poles alternately, and the protrusions 53b are provided with N poles and S poles alternately. ,
It is formed integrally with the magnetic ring 53, and
As shown in FIG. 2, it is formed into an arcuate cross section. still,
The protrusion 53b may be formed separately from the magnetic ring 53 and attached by attachment means such as welding or set screws.

When the clutch lever 81 is operated to disengage the clutch 7 and the spool 3 is rotated freely for casting, the conductor 50 provided on the spool 3 or the spool shaft 4 along with the spool 3 is It rotates within the magnetic field of the magnet 51 and the protrusion 53b of the magnetic ring 53, and as the conductor 50 rotates, the direction of the magnetic flux passing through the conductor 50 changes in the direction of rotation. This change in magnetic flux generates an eddy current in the conductor 50, and according to Fleming's left hand rule, the conductor 50
A magnetic force is generated in the direction opposite to the direction of rotation at zero, and brakes the spool 3.

This braking can be controlled by adjusting the magnetic ring 53 using the operating tool 54. That is, when the operating tool 54 is rotated,
This operating force is applied from the engaging portion 54a to the engaging protrusion 53a.
The magnetic ring 53 is rotated, and this rotation changes the positional relationship between the projection 53b provided on the magnetic ring 53 and the magnet 51 provided on the magnet ring 52, and The number of magnetic fluxes passing through the spool 50 can be changed, and by this change, the braking force acting on the spool 3 can be adjusted.

This holder 55 is formed by bending a plate body, and has a mounting portion on one end attached to the side plate 22 and an engaging portion 55a on the other end engaged with the uneven strip 53c. The holder 55 is bent when the magnetic ring 53 is rotated, and the uneven strip 53c is bent.
It disengages from the

Although the magnet 51 is formed separately from the magnet ring 52 and fixed by a fixing means such as adhesive, it is also possible to make the ring 52 of synthetic resin and embed it together when molding it. . Further, the magnet 51 may be formed using a magnetization method, or may be formed in a plurality or in an annular shape.

Further, the magnet ring 52 is fixed to the bearing housing 21, and the magnetic ring 53 is fixed to the bearing housing 21.
Although it is assumed that the rotation is possible, it may be the opposite.

As described above, the present invention has a cylindrical electrical conductor attached to the spool or spool shaft, a magnet ring surrounding the conductor on one of the inner and outer peripheries, and a magnetic ring on the other. Since the magnetic rings are integrally provided with a plurality of protrusions that protrude in the direction of the magnets, the magnetic force of the magnets can be used to brake the spool while one of the rings The movable ring is rotatably supported on the reel body, and the movable ring is rotated by an operating tool to change the effective magnetic flux density over a wide range and adjust the braking force. In addition to being able to perform arbitrary adjustments, the accuracy of the adjustment can also be improved, and backlash can be reliably prevented.

Furthermore, by arranging a magnetic ring on the inner or outer periphery of the conductor, the repulsive force of the magnetic flux when adjusting the braking force by rotating the movable ring, that is, the repulsive force that pulls the movable ring in the return direction, can be reduced. The pulling force can be reduced, and as a result, the adjusted state of the movable ring can be maintained sufficiently even with a weak holding force.

Furthermore, by installing a flexible holder that engages with a large number of uneven stripes provided on the outer circumferential surface of the magnetic ring, the flexible holder is activated when the operating tool is rotated. Due to the restoring action, the adjustment can be confirmed with a click feeling, and the adjustment state of the braking force can be reliably maintained at the desired position, in conjunction with the structure that can reduce the above-mentioned pulling force. Since the magnetic ring is integrally provided with a plurality of protrusions that protrude in the direction of the magnet, the reel as a whole can be made light and compact while still achieving the above-mentioned effects, and the structure and assembly are simple and easy. As a result, the effect of reducing manufacturing costs can be obtained. Furthermore, since there is no need to specify the north and south poles of the magnet, assembly is easy.
Assembling work efficiency can be improved.
