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.

During casting, the fishing line wound on the spool is pulled out by the weight of the tackle attached to the end of the line, but the free rotation of the spool becomes faster than the speed at which the fishing line is pulled out, causing a so-called back crash. This back crash can cause the fishing line to become tangled or get caught between the spool and the reel body, so for this reason reels are generally equipped with a brake.

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, a force is applied to the rotating member in the opposite direction to the rotating direction to brake the spool, and the stationary member is moved in the axial direction of the spool shaft relative to the reel body. It has been proposed that the braking force can 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 the other is fixed on the spool, so when the spool is removed from the reel body in order to replace the spool with a spool wound with a fishing line of a different thickness, the magnet is attached to the outside. When the spool is replaced at a fishing spot, particularly at a sandy beach, iron sand may enter and be attracted to the magnet, causing a problem in which the braking force is impaired.

Therefore, the present invention was devised in view of the above-mentioned problems.It is possible to make a brake consisting of a magnet and a metal conductor into a unit, making assembly easy, and yet sealing the magnet from the outside even when changing the spool. The main point is to provide a double-axis reel that allows for

That is, in the present invention, a bearing housing for the spool shaft is provided on one end side of the spool shaft of the reel body, and one end of the cylindrical shaft having a non-circular inner peripheral surface is rotated through the bearing within the bearing housing. The first ring is fixed by freely supporting the spool shaft, and a plurality of magnets are provided around the side surface, and a pair of axially opposing first and second rings are arranged concentrically with the spool shaft; While the second ring is rotatably supported, an electric conductor is provided on the outer periphery of the intermediate portion of the cylindrical shaft and is interposed between the rings and faces each of the magnets, and on the open side of the bearing housing. , a disc-shaped sealing material extending radially inward from the inner peripheral side of the bearing housing and having an inner peripheral surface facing the outer periphery of the other end of the cylindrical shaft at a slight interval; The device is characterized in that an operating tool for the second ring is provided.
While the braking force can be adjusted arbitrarily by rotating the ring with the operating tool, the disc-shaped sealing material can easily provide dustproofing, and it can also be easily assembled to the reel body.

Further, the clutch 7 is constructed by providing a flat surface at the intermediate portion of the spool shaft 4 and providing the pinion gear 6 with a cylindrical portion having a non-circular inner surface that engages with the flat surface. By separating the cylindrical portion of the pinion gear 6 from the flat surface forming portion of the spool shaft 4 by operating the operating mechanism 8, the spool shaft 4 and the spool 3 fixed to the spool shaft are made freely rotatable.

This allows the clutch lever 81 to be held at the forward movement end position.

The present invention has a reel configured as described above,
The brake 5 during free rotation of the spool 3 is formed as follows.

That is, as shown in FIG. 1, one end of a cylindrical shaft 50 having a non-circular inner circumferential surface 50a (see FIG. 4) is rotatably supported by the bearing 10 in the bearing housing 21, and , the spool shaft 4
A non-circular outer circumferential surface 4a that engages with the non-circular inner circumferential surface 50a of the cylindrical shaft 50 is formed at the shaft end of the cylindrical shaft 50, and this outer circumferential surface 4a engages with the non-circular inner circumferential surface 50a of the cylindrical shaft 50. One end of the spool shaft 4 is rotatably supported via the cylindrical shaft 50, and a plurality of magnets 5 are attached to the side surface of the bearing housing 21.
A pair of first and second rings 53 and 54 facing each other in the axial direction and having numbers 1 and 52 are arranged concentrically with the spool shaft 4, and the first ring 53 is located on the open side of the bearing housing 21. and the second
A ring 54 is rotatably supported on the bottom wall side of the bearing housing 21, and a disk is provided on the outer periphery of the intermediate portion of the cylindrical shaft 50, interposed between the rings 53 and 54, and facing the magnets 51 and 52. An electrical conductor 55 is provided on the open side of the bearing housing 21, extending radially inward from the inner peripheral side of the bearing housing 21, and facing the outer periphery of the other end of the cylindrical shaft 50 at a slight interval. A disk-shaped sealing material 60 having an inner peripheral surface is provided, and the cover 23
an engaging pin 56 that engages with the second ring 54;
An operating tool 58 having a knob 57 and a knob 57 is provided, and the knob 57 is exposed outside the cover 23 to enable the second ring 54 to be operated from the outside.

However, in the above configuration, the magnet 5
A pair of first and second rings 5 with 1,52
3 and 54 and the conductor 55 constitute the brake 5, the conductor 55 is provided separately from the spool shaft 4, and the bearing housing 2
1, the rings 53, 54 and the conductor 55 constituting the brake 5 are assembled in advance on the basis of the bearing housing 21. It can be made into a unit together with the bearing housing 21.

Therefore, after the bearing housing 21, in which the brake 5 is assembled into a unit, is assembled into the side plate 22, the spool shaft 4 is attached to the cylindrical shaft 50.
Assembling can be done simply by fitting the two together.

Moreover, a disk-shaped sealing material 60 is provided on the open side of the bearing housing 21, and the first ring 5
3, it is possible to close the bearing housing 21 together with the cylindrical shaft 50, and even when the spool shaft 4 is detached from the cylindrical shaft 50, each ring 53 installed inside the bearing housing 21 can be closed. ,54 magnets 51,5
2 is no longer exposed to the outside, making it possible to protect it from dust.

Therefore, even when replacing the spool 3 at a fishing spot, especially at a sandy beach, the iron sand may not be attached to the magnets 51, 5.
2 can be reliably prevented from adhering to the brake pad, and the braking force can always be kept constant.

The inner peripheral surface of the bearing housing 21 is a first
As shown in the figure, it is stepped, with the open side being the larger diameter, and its inner peripheral surface is formed with serrations or other unevenness, and unevenness is also formed on the outer peripheral surface of the first ring 53, and these unevennesses are fitted together and fixed by a retaining ring 61. The small diameter part of the bearing housing 21 has a circular inner peripheral surface as shown in Figure 4, and on the center side of this small diameter part,
A support cylinder 21a is provided, and the second ring 5 is inserted between the outer circumferential surface of the support cylinder 21a and the inner circumferential surface of the small diameter portion.
4 is rotatably fitted thereto, and a retaining ring 62 prevents axial movement.

Therefore, with the above configuration, each ring 5
3, 54 and the cylindrical shaft 50 can be easily assembled from the open side.

Further, the bottom wall of the bearing housing 21 is provided with an arc-shaped elongated hole 21b centered on the rotation center of the second ring 54 as shown in FIG. A long hole 23a in the shape of an arc is provided in the long hole 23a provided in the cover 23, and a positioning body 63 is provided in the long hole 23a provided in the cover 23 to engage with the uneven strip 59a provided in the shaft portion 59 of the operating tool 58.

This positioning body 63 is mainly formed of a leaf spring, and its elastic force holds it in a part of the elongated hole 23a as shown in FIG.

Therefore, when the clutch lever 81 is operated to disengage the clutch 7 and the spool 3 is rotated freely for casting, the conductor 55 provided on the cylindrical shaft 50 which rotates together with the spool 3, It rotates within the magnetic field of the magnets 51 and 52 facing each other with the conductor 55 in between, and as the conductor 55 rotates, the direction of the magnetic flux passing through the conductor 55 changes in the direction of rotation. Then, due to this change in magnetic flux, an eddy current is generated in the conductor 55, and according to Fleming's left hand rule, the conductor 55
A magnetic force is generated in the direction opposite to the rotational direction of the spool 3, thereby braking the spool 3.

This braking force can be controlled by adjusting the second ring 54 using the operating tool 58.

That is, when the operating tool 58 is rotated, the second ring 54 rotates, and the rotation of the second ring 54 changes the relative position of the magnets 51 and 52, which face each other with the conductor 55 in between, in the circumferential direction. The number of magnetic fluxes passing through the conductor 55 can be changed, and by this change, the braking force acting on the spool 3 can be adjusted.

It should be noted that the magnets 51 and 52 provided in each of the rings 53 and 54 are provided to face each other. For example, when the magnet of the first ring 53 is set as the north pole, the magnet 5 of the second ring 54
2 is the S pole, and each ring 53, 54
In this case, N poles and S poles may be provided alternately.

Further, the magnets 51 and 52 may be formed separately from the rings 53 and 54 and fixed by a fixing means such as adhesive, or the rings 53 and 54 may be made of synthetic resin and embedded into the same during molding. Alternatively, it may be formed using a magnetization method.

Further, the magnets 51 and 52 can be formed in any shape, but if they are formed into a rectangular shape, more linear braking force adjustment becomes possible.

Further, although the operating tool 58 is directly coupled to the second ring 54 using the pin 56, it may be linked indirectly via a gear or the like. Further, the sealing material 60 is formed separately from the first ring 53 and attached to the outside of the first ring 53, but the inner diameter of the first ring 53 is brought close to the outer diameter of the cylinder shaft 50 and integrated. It may be formed into

As described above, in the present invention, one end of the cylindrical shaft is rotatably supported in the bearing housing via the bearing, and an electrical conductor is provided on the outer periphery of the intermediate portion of the cylindrical shaft, interposed between the rings. In addition, since the housing includes a pair of first and second rings facing each other in the axial direction and having a magnet facing the conductor, a brake is provided during free rotation of the spool. While braking the spool using the magnetic force of the magnet, the brake can be assembled into a unit based on the bearing housing, and the inside of the bearing housing can be controlled using the first or second ring. It closes together with the cylindrical shaft and shields the magnets provided on each ring from the outside to make it dustproof. Therefore, even when changing the spool at a fishing spot, especially at a sandy beach, iron sand will not enter and be attracted to the magnets. It is possible to reliably prevent this and maintain the braking force at the desired adjusted braking force.
