Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a double-bearing reel, and more particularly, to a double-bearing reel in which a spool shaft having a spool is freely rotatably supported via a pair of bearings.

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 spool shaft rotates freely. 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, the brake shoe is brought into sliding contact with the brake drum to perform braking, so that the friction 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 problems, a magnetic brake equipped with a magnet and an electric conductor is used, and one of the magnet and the electric conductor in this magnetic brake is made to rotate together with the spool, and the other is attached to the reel body. fixed, one rotation rotates the magnetic flux 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 rotational direction of the spool, so as to brake the spool, and , the fixed side member is movable with respect to the reel body,
A double-bearing reel has been proposed in which the relative position of the magnet and the electrical conductor is adjusted by operating an adjustment body provided axially outward of the spool.

With this method, there is no adhesive part, so 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 adjusted by operating the adjustment body, and the braking force is controlled by the rotation of the spool. Although the braking force can be increased or decreased in proportion to the number of rotations, even if the braking force is adjusted by operating the adjustment body, it is not possible to adjust the rate of change in the braking force with respect to the spool rotation speed. It is not possible to adjust the braking force accordingly. In other words, for example, if the braking force that is pre-adjusted before casting is set to be 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 larger braking force will be applied to the spool. As a result, the casting distance of the fishing line becomes shorter, and if the braking force is set to the minimum value for the spool rotation speed at the initial stage of casting, the casting distance of the fishing line can be increased, but on the other hand, crashing occurs. There was a problem that got easier.

The present invention was invented in view of the above-mentioned problems.The purpose of the present invention is to be able to adjust the braking force to suit the angler's preference before casting, to extend the casting distance of the fishing line, and to make it easy to use during casting. The object of the present invention is to provide a double-bearing reel that can reliably prevent backlash by performing certain operations.

That is, the basic idea of the present invention is to be able to adjust the braking force, which increases or decreases depending on the rotational speed of the spool. A double-bearing reel having a magnetic brake supporting an arcuate electrical conductor on one side and having a magnet radially opposed to the conductor on the other side, the reel having one side between the conductor and the magnet. a first adjusting body that supports the spool so as to be movable in the radial direction and that adjusts the position of the movable member of the conductor and the magnet to set a reference braking force; a second adjustment body that adjusts the position of the movable side member adjusted by and changes the reference braking force adjusted by the first adjustment body, and is provided so as to be independently operable, and the second adjustment body is operated. The fishing rod is characterized in that the reel body is provided at a position that can be operated by the hand that grips the fishing rod to which the reel body is attached.

The movement of the control body 53 is transmitted from the spring receivers 53b, 53b to the holding body 52, and the holding body 52 is driven by the control body 53 to move the control body 53 in the radial direction relative to the conductor 51. while adjusting the position of the magnet 50 held by the holding body 52 with respect to the conductor 51, the first adjusting body 55 is displaced radially outward relative to the supporting position of the first adjusting body 55 in the reel body 1. At this position, it protrudes into the bearing housing 21 through the window hole 21e provided on the outer periphery of the bearing housing 21, and comes into contact with the aperture 52e provided on the outer surface of the holder 52 on the engaging portion 52d side, as shown in FIGS. 3 and 4.

In the above configuration, the magnet 50 is
It is held on one side of the outer surface of a cylindrical holding body 52, and within the range from the maximum clearance position (position shown in Figure 3) to the minimum clearance position (position shown in Figure 4) with the conductor 51. To enable position adjustment, in the drawing, one S-axis magnet is provided on each side of the N-axis magnet.
Further, this magnet 50 has an arc-shaped magnetic plate 5 in a concave holding portion 52a provided on the outer surface of the holding body 52.
Although the holding body 52 is fixed by a fixing means such as an adhesive through the fixing member 7, the holding body 52 may be made of synthetic resin and embedded in the holding body 52 when molded.

Further, the control body 53 is interposed between the side surface of the holding body 52 and the bottom wall 21b of the bearing housing 21, so that when the first adjustment body 55 performs adjustment, the control body 53
The operating force is applied from the cam 55b to the engagement protrusion 53c.
The information is transmitted to the control body 53 through the spring receivers 53b, 53b of the control body 53 to the holder 52 provided separately from the control body 53, and the holder 52 is transmitted to the control body 53.

The operating force of the adjustment body 56 is directly transmitted from the contact 52e to the holding body 52, and the holding body 52 is controlled by the control body 5.
3, when the second adjustment body 56 is released, the holding body 52 is moved in a direction against the force of the springs 54, 54.
This is done as if it were restored by the restoring force of 4.

Incidentally, when the second adjusting body 56 is operated, the engaging protrusion 53c provided on the controlling body 53 engages with the cam 55b of the first adjusting body 55, so that movement of the controlling body 53 in the radial direction is restricted. Therefore, this control body 53
does not move, and only the holding body 52 moves.

Further, the guide hole 21c provided in the bearing housing 21 is formed in an oval shape extending in the moving direction of the control body 53 to prevent rotation of the control body 53 with respect to the support tube 21a, and to prevent rotation of the control body 53 with respect to the support tube 21a only in the radial direction. It is done as if it were moved. Incidentally, rotation of the holding body 52 with respect to the support tube 21a is prevented by the springs 54, 54.

Further, a cam 55b provided on the first adjusting body 55
is formed by recessing the inner surface of the adjustment body 55, but it may also be made to protrude outward from the inner surface.

The second adjustment body 56 also includes a known thumb rest 56b, which is installed between the first and second side frames 1 and 2, on which the thumb of the hand gripping the fishing rod to which the reel body 1 is attached can be placed. The thumb rest 5, which is formed by using the
6b, and a support shaft 5 fixed to the thumb rest 56b.

The arm 56d is disposed within the cover 23, and the contact portion 56a is thrust into the bearing housing 21 through the window hole 21e of the bearing housing 21 and brought into contact with the abutment 52e of the holder 52.

Therefore, when the clutch lever 81 is operated to disengage the clutch 7 and the spool 3 is rotated freely for casting, the conductor 51 provided on the spool 3 or the spool shaft 4 along with the spool 3 is The conductor 51 rotates within the magnetic field of the magnet 50, and with this rotation, the conductor 51
The direction of the magnetic flux passing through changes in the direction of rotation. Due to this change in magnetic flux, the conductor 51
An eddy current is generated, and according to Fleming's left-hand rule, a magnetic force is generated in the direction opposite to the direction of rotation of the conductor 51, thereby braking the spool 3.

This braking can be controlled by adjustment by the first adjustment body 55 and adjustment by the second adjustment body 56.

That is, in the case of using the first adjustment body 55, the first
When the adjustment body 55 is rotated, this operating force is transmitted from the arc-shaped cam 55b to the control body 53 via the engagement protrusion 53c, and the engagement protrusion 53c of the cam 55b is rotated.
As the engagement position with the spring receiver 53 changes, the control body 53 moves in the radial direction with respect to the support tube 21a, and this movement of the control body 53 causes the spring receiver 53 to move in the radial direction.
b, 53b to the holding body 52, and this holding body 52 is driven by the control body 53 and moves in the radial direction with respect to the support tube 21a, and the conductor 51 of the magnet 50 held by the holding body 52 is moved. The magnetic flux density passing through the conductor 51 can be changed by changing the position between the maximum clearance position and the minimum clearance position, and by this change, the braking force acting on the spool 3 can be adjusted. . Therefore, before casting, it is possible to adjust the braking force to the minimum level according to the angler's preference.

In addition, in the case of using the second adjustment body 56, extend the thumb of the hand that grips the fishing rod to which the reel body 1 is attached and touch the thumb rest 56b of the second adjustment body 56, and rotate the fishing rod in the direction of the arrow X in FIG. This operating force is applied to the contact portion 56 of the second adjustment body 56.
a directly to the holding body 52 via the contact 52e, and this holding body 52 is moved radially outward against the support cylinder 21a and the control body 53 against the springs 54, 54, and with this movement, the holding body 52 body 52
The position of the magnet 50 held in relation to the conductor 51 is displaced from the maximum clearance side position adjusted by the first adjustment body 53 to the minimum clearance side position,
The magnetic flux density passing through the conductor 51 increases, and the braking force increases.

Therefore, when casting, by operating the second adjusting body 56 with the hand holding the fishing rod to which the reel body 1 is attached near the landing point of the fishing line, the braking force can be rapidly increased, and the crashing can be ensured. It is possible to eliminate it. Note that, after the operation is released, the second adjusting body 56 returns together with the holding body 52 due to the restoring force of the springs 54, 54.

Further, the adjusted state by the first adjusting body 55 can be adjusted by having an engaging portion that engages with a large number of uneven stripes 55c provided on the outer peripheral surface of the first adjusting body 55, as shown in FIGS. 1 and 2, for example. This is maintained by a blocking body 58, which is formed of a flexible plate, one end of which is attached to the outer surface of the side plate 22 by a fixing means such as caulking, and the other end of which is secured. The mating portion is engaged with the uneven strip 55c.
The blocking body 58 is bent when the first adjusting body 55 is rotated to release the engagement with the uneven strip 55c.

Further, in the figure, 59 is a magnetic ring provided on the inner surface of the bearing housing 21 facing the outer peripheral surface of the conductor 51, and 60 is a C-shaped retaining ring that prevents the holder 52 from moving in the axial direction with respect to the support cylinder 21a.

It may be formed integrally with 52. In this case, for example, an escape space for the engagement protrusion 53c extending along the cam 55b in the same direction as the guide hole 21c is provided outside the cam 55b in the first adjustment body 55, and the holding body 52 A spring is interposed between the magnet 50 and the bearing housing 21 to urge the magnet 50 in the direction in which the clearance between the conductor 51 is maximized, and the holding body 52 is adjusted by rotating the first adjusting body 55. is moved in the radial direction of the conductor 51 against the spring, and the holding body 52 is moved in the radial direction of the conductor 51 against the spring by rotating the second adjustment body 56. It is structured as follows.

Further, the second adjustment body 56 has a thumb rest 56b.
In addition to being formed using the thumb rest 56b, it may be formed separately from the thumb rest 56b. Further, the operation section of the second adjustment body 56 is connected to the first and second side frames 1,
