Description

  The present invention relates to a bait reel, an electromagnetic brake used for the bait reel, and a bait reel spool. More specifically, the present invention relates to a bait reel for controlling rotation of a spool using an electromagnetic brake, an electromagnetic brake used for the bait reel, and a spool for a bait reel.

  As reels used for fishing, there are generally a spinning reel and a double-bearing type bait reel. Of these, bait reels have the advantage of being able to use thicker yarns and being easier to control, as compared to spinning reels, because bait reels can directly receive the force applied to the yarns by the spool. Therefore, when using a heavy lure or gimmick, it is preferable to use bait reel.

  However, while bait reel has the above advantages, a phenomenon (so-called backlash) in which a thread is entangled with a spool during casting is apt to occur. Backlash is a phenomenon that occurs when the rotation speed of the spool becomes faster than the speed of the lure thrown away by casting, and the stage where the lure or the like has crossed the top of the flight trajectory or the lure has landed It is said to occur at the stage.

  In general, as a method of preventing the above-described backlash, a method of generating frictional braking force by pressing a spool with a thumb or the like during casting (so-called summing) has been adopted. However, this summing operation can only be properly performed by experienced veterans, and is difficult to handle for anglers who are not accustomed to using bait reel.

  Therefore, various bait reels have conventionally been developed using a magnetic braking method (for example, Patent Documents 1 to 5). The bait reels of these documents generate an eddy current in a conductor by applying a magnetic force to a conductor that rotates integrally with the spool in accordance with the rotation speed of the spool. Then, the braking force of the spool is changed depending on the strength of the generated eddy current to suppress backlash.

Patent Literatures 1 and 2 disclose a bait reel including a cylindrical conductor that rotates integrally with a spool, and a cylindrical magnet connected and fixed to a frame so as to cover a circumferential outer surface of the conductor. I have.
In Patent Literature 3, a conductor is attached so as to cover a side opening of a bobbin main body of a spool, and a cylindrical magnet is provided so as to face the conductor and rotate integrally with the spool. A bait reel is disclosed, which describes that such a magnet is provided movably along an axial direction by a moving mechanism.
Patent Literatures 4 and 5 disclose a bait reel in which a conductor is provided on the inner peripheral surface of a bobbin main body portion of a spool, and a magnet for applying a magnetic force to the conductor is provided. Magnet moving means is provided. In the technique of Patent Document 5, the magnet is formed so as to be movable in the bobbin in the axial direction of the spool shaft in accordance with the rotation of the spool.
Patent Literature 6 discloses a bait reel including a bobbin main body of a spool formed of a conductive material, and a magnet provided with a protrusion on a side edge of the bobbin main body and arranged so as to sandwich the protrusion. It has been disclosed.

Japanese Utility Model Publication No. 54-76297 Japanese Utility Model Publication No. 54-80993 Japanese Utility Model Application Laid-Open No. 58-117867 JP-A-7-274782 JP 2013-236606 A Japanese Utility Model Publication No. 58-41171

However, the bait reels of Patent Documents 1 to 5 have a structure in which a conductor is separately provided or the bobbin itself is a conductor, so that the weight of the spool increases. Therefore, the moment of inertia when the spool is rotated increases. Further, in the bait reel disclosed in Patent Document 6, the weight of the end portion of the spool increases, so that the rotational moment increases. That is, in the techniques of Patent Documents 1 to 6, as a result of using the electromagnetic brake, there is a problem that the rotation performance is reduced due to an increase in the weight of the spool and it is difficult to obtain a desired flight distance.
In addition, the bait reels of Patent Documents 1 to 6 have a structure in which a backlash preventing means is provided outside the spool, so that the width of the reel body becomes long. For this reason, there is also a problem that it is difficult to grip because it is held in such a manner that it is wrapped in the palm of one hand together with the fishing rod at the time of winding.

  The present invention has been made in view of the above circumstances, and has as its object to provide a bait reel, an electromagnetic brake used for the bait reel, and a bait reel spool that have improved operability while preventing backlash.

The magnet 11 is arranged near the side of the cylindrical portion 3b provided on the shaft 3a of the spool shaft 3. In other words, the magnet arrangement structure 10 can supply the magnetic force generated by the magnet 11 to the cylindrical portion 3b from the radial direction of the spool shaft 3.

  The number and arrangement of the magnets 11 of the magnet arrangement structure 10 are not particularly limited as long as the magnets 11 can supply a magnetic force to the cylindrical portion 3b from the radial direction of the spool shaft 3 as described above. The number of magnets 11 may be one, or a configuration having a plurality of magnets 11 more than that may be employed.

  Here, “plurality” means having two or more magnets 11. In other words, that the magnet arrangement structure 10 has a plurality of magnets 11 means that the magnets 11 have various configurations such as two magnets, three magnets, four magnets, and more magnets. it can.

  Specifically, if there are two magnets 11, the magnet arrangement structure 10 can be arranged in a state of facing each other so as to sandwich the spool shaft 3. If there are three or more magnets 11, they can be arranged rotationally symmetric about the spool shaft 3, or they can be arranged rotationally symmetric and at equal angular intervals. If there are four magnets 11, four magnets 11 can be arranged in a cross shape around the spool shaft 3 if they are arranged so as to be rotationally symmetric and at equal angular intervals. Further, if the number of magnets 11 is increased to form an annular shape surrounding the spool shaft 3, the magnet 11 can be arranged to surround the spool shaft 3.

When the magnet arrangement structure 10 is arranged as described above, a part or all of the magnets 11 constituting the magnet arrangement structure 10 are attached to the cylindrical portion 3 b of the spool shaft 3 in the axial direction of the spool shaft 3. They are arranged to overlap. That is, when the spool shaft 3 is viewed from the radial direction, the magnet arrangement structure 10 is arranged so that a part or all of the magnet 11 overlaps the cylindrical portion 3b.
Specifically, when viewed from the radial direction of the spool shaft 3, the end of the cylindrical portion 3 b on the bearing B side is closer to the end of the magnet 11 on the web portion 4 b side of the bobbin 4 in the axial direction of the spool shaft 3. Are also located inward. For example, as shown in FIGS. 2 and 3, between the magnet 11 and the spool shaft 3, the magnet arrangement structure 10 has a space 10 h into which a part of the cylindrical portion 3 b can enter. The structure 10 is formed.

A state in which a part of the cylindrical portion 3b has penetrated into a space 10h formed inside the magnet arrangement structure 10 (that is, the spool shaft 3 side in a state where the magnet arrangement structure 10 is mounted), An outline of a state where the part and a part of the cylindrical part 3b overlap will be described.
Hereinafter, as shown in FIG. 3, a specific example will be described in which the magnet arrangement structure 10 is formed using a plurality of magnets 11 so as to be annular in cross section. The details will be described later.

As shown in FIGS. 1 to 3, the magnet arrangement structure 10 includes a plurality of magnets 11 formed in an annular shape. Inside the annular magnet 11, a space 10h surrounded by an inner peripheral surface (that is, a surface along the inner edge of the magnet 11 on the spool shaft 3 side) is formed.
The inner diameter of the space 10h of the annular magnet 11 is formed to be larger than the outer diameter of the cylindrical portion 3b. That is, when the magnet arrangement structure 10 is arranged at a predetermined position, the space 10h becomes a space into which the cylindrical portion 3b of the spool shaft 3 is inserted (see FIGS. 1 to 3).
Specifically, as shown in FIGS. 2 and 3, the magnet arrangement structure 10 is attached with a part of the cylindrical portion 3 b inserted inside the annular magnet 11 of the magnet arrangement structure 10. I have. In other words, the magnet arrangement structure 10 is mounted between the frames f so as to surround the cylindrical portion 3b of the spool shaft 3 (that is, the cylindrical portion 3b attached to the shaft 3a) (FIG. 1 to 4).

  As shown in FIG. 1, a handle H is connected to the shaft 3a of the spool shaft 3. Therefore, when the handle H is turned, the bobbin 4 is rotated via the shaft 3a connected to the handle H. Since the cylindrical portion 3b connected to the shaft 3a is also connected to the bobbin 4, the cylindrical portion 3b is also provided so as to rotate integrally with the bobbin 4 (integral rotation).

  Also, as shown in FIG. 1, a level winder LW for evenly winding the yarn is provided in front of the bait reel 1 (that is, in the direction in which the yarn is unwound, in FIG. 1, above the paper surface). A clutch lever L connected to a clutch mechanism that adjusts the connection between the spool unit 2 and the handle H is provided behind the reel 1 (that is, on the user side, below the paper surface in FIG. 1).

  When the clutch lever L is depressed downward from the ON state of the clutch (that is, the state in which the rotational driving force of the handle H can be transmitted to the spool shaft 3), the clutch is turned OFF (that is, the rotational driving force of the handle H is spooled). (A state in which transmission to the shaft 3 is interrupted). The clutch can be returned from the OFF state to the ON state by rotating the handle H.

  With the configuration as described above, when casting a lure or the like using the bait reel 1 (hereinafter, referred to as bait reel 1), the following effects are obtained.

  First, with the bait reel 1 attached to the fishing rod, the clutch lever L was turned off, the fishing line wound around the bobbin 4 of the spool portion 2 was drawn out, passed through the level winder LW, and then provided on the fishing rod on the grip side. The fishing line is passed from the guide to the top guide in order, and when the top guide has been passed, the clutch lever L is turned ON. Then, a lure, a device or the like is connected to the tip of the fishing line.

  Next, when casting a lure or the like, the fishing line wound around the bobbin 4 is pressed with a thumb or the like so that the bobbin 4 of the spool unit 2 does not rotate without permission with the clutch lever L turned off. The lure or the like can be cast to a desired position by entering the posture and releasing the thumb or the like holding the fishing line at the timing of throwing the lure or the like.

  The cast lure or the like and the fishing line connected to the lure or the like reach a target place while drawing a parabola. At this time, in the initial stage of the casting, the fishing line is pulled out from the bobbin 4 of the spool portion 2 by being pulled by a lure or the like, so that the rotation speed of the spool portion 2 is not so high. Thereafter, the rotation speed of the spool unit 2 also increases so as to follow the flight speed of the cast lure or the like.

Then, the flying speed of the casted lure or the like decreases after passing near the top of the parabola.
On the other hand, the rotational speed of the spool portion 2 tends to keep rotating according to the law of inertia even when the cast lure or the like passes near the vertex of the parabola.
Then, if the spool portion 2 continues to rotate as it is, the amount of the fishing line supplied from the bobbin 4 of the spool portion 2 becomes larger than the amount of the fishing line pulled by a lure or the like. A phenomenon (a so-called backlash) that the amount of yarn becomes entangled occurs.

  However, the bait reel 1 has a structure in which the cylindrical portion 3b is located in a space 10h located inside the magnet arrangement structure 10. For example, when the magnet arrangement structure 10 is constituted by the annular magnet 11 as shown in FIG. 3, the structure is such that the arrangement is made so as to surround the cylindrical portion 3b. The cylindrical portion 3b is connected to the bobbin 4 of the spool portion 2 so as to rotate integrally therewith. The tubular portion 3b may be formed separately from the bobbin 4 and then connected to the web portion 4b of the bobbin 4, or the tubular portion 3b may be formed integrally with the bobbin 4. You may.

Therefore, if the bobbin 4 of the spool portion 2 rotates as described above in a state where the magnet arrangement structure 10 and the cylindrical portion 3b at least partially overlap, the inner surface of the magnet arrangement structure 10 in the cylindrical portion 3b of the spool shaft 3 will be described. An eddy current can be generated by the action of the magnet arrangement structure 10 at a location facing the eddy current.
In addition, with the rotation of the bobbin 4 of the spool portion 2, a force in the opposite direction to the rotation, that is, a braking force (braking force) can be generated in the cylindrical portion 3b. In other words, the magnet arrangement structure 10 and the cylindrical portion 3b function as an electromagnetic brake.
In particular, when the magnet arrangement structure 10 is formed by the annular magnet 11 as shown in FIG. 3, the magnet arrangement structure 10 surrounds the cylindrical portion 3b, so An eddy current can be generated appropriately.

  Then, it is possible to prevent the bobbin 4 of the spool portion 2 from rotating excessively due to the braking force of the magnet arrangement structure 10 and the cylindrical portion 3b by the electromagnetic brake. If the excessive rotation of the bobbin 4 is prevented, the amount of the fishing line supplied from the bobbin 4 of the spool portion 2 at the time of casting can be prevented from being larger than the amount of the fishing line pulled by a lure or the like. Become.

  Therefore, if the above function is performed at the timing when the amount of the fishing line supplied to the bobbin 4 of the spool portion 2 and the amount of the fishing line pulled by the lure or the like start to shift or earlier than such timing, the bobbin 4 of the spool portion 2 Can be prevented from over-rotating, so that it is possible to prevent backlash that occurs during casting or the like.

In addition, the bait reel 1 has a structure in which the above-described braking force is generated with the cylindrical portion 3b of the spool shaft 3 penetrating into the internal space 10 of the magnet arrangement structure 10, that is, the magnet near the rotation shaft of the spool portion 2. This is a structure in which the arrangement structure 10 is arranged. For this reason, the moment of inertia generated when the bobbin 4 of the spool portion 2 is rotated can be reduced. In other words, since the moment of inertia can be reduced, the rotation performance of the bobbin 4 of the spool unit 2 can be maintained.
Then, as compared with a bait reel equipped with a conventional electromagnetic brake, it is possible to suppress a decrease in the rotational performance of the spool portion 2, so that when the lure is cast, the lure or the like can be skipped a desired flight distance. Will be able to

  In summary, the use of the bait reel 1 of the present embodiment can prevent backlash that occurs when casting, and can appropriately cast a lure or the like at a desired distance.

  The “cylindrical portion 3b” in the specification corresponds to the “conductive member” in the claims.

<Details of magnet arrangement structure 10>
Next, the magnet arrangement structure 10 constituting the electromagnetic brake of the rotation control mechanism of the bait reel 1 will be described in detail.

  The size of the magnet arrangement structure 10 is not particularly limited as long as at least a part of the cylindrical portion 3b attached to the shaft 3a of the spool shaft 3 can be arranged in the internal space 10h so as to overlap in the internal space 10h as described above. . For example, it may be appropriately adjusted according to the size of the bait reel 1 and the strength of the magnetic force of the magnet 11 described later.

The arrangement shape of the plurality of magnets 11 of the magnet arrangement structure 10 is a shape (hereinafter simply referred to as an arrangement) in which a magnetic force can be supplied to the cylindrical portion 3b of the spool shaft 3 from the radial direction of the spool shaft 3 as described above. The shape is not particularly limited.
For example, in addition to the case where a plurality of magnets 11 are used to form an annular shape in cross section as described above, two magnets 11 face each other along the circumferential direction of the spool shaft 3 so as to sandwich the spool shaft 3. A plurality of magnets 11 are arranged on the spool shaft 3 such as an arranged one, three or four magnets 11 arranged rotationally symmetrically, or a three or four magnets 11 arranged rotationally symmetrically and at equal angular intervals. Various arrangements can be made in the radial direction so as to be arranged.

In addition, the method of forming the arrangement shape in which the number of the magnets 11 is two or three as described above is not particularly limited.
For example, a predetermined number of magnets 11 may be reduced in accordance with the braking force, the technical skill of the user, the weight of the bait reel 1, etc. from a plurality of magnets 11 formed into an annular shape in cross section using a spool shaft. 3 may be formed so as to be rotationally symmetrical. In such a case, by arranging them at equal angular intervals, it is possible to obtain an arrangement shape that is less likely to be eccentric, so that there is an advantage that operability can be stabilized.

  When formed in an annular shape using a plurality of magnets 11, the concept is not limited to the annular shape in a cross-sectional view as described above, and is a concept including not only an endless annular shape but also a C-shaped shape in which a part is missing. In addition to an annular shape in a plan view, an annular shape in a sectional view is also meant.

  Further, in the above example, the case where a plurality of magnets 11 are used to form an annular shape has been described, but one magnet 11 is formed so as to have a ring-like shape, a tubular shape, or the like in a cross-sectional view in plan view. Needless to say, it may be.

(Details of magnet 11)
Next, details of the magnet 11 of the magnet arrangement structure 10 will be described.
The magnet arrangement structure 10 is a member having at least one magnet 11 as described above, and the magnet 11 is arranged in the radial direction of the spool shaft 3 so as to supply a magnetic force to the cylindrical portion 3b of the spool shaft 3. If so, the arrangement shape is not particularly limited.
Hereinafter, a method of arranging a plurality of magnets 11 in a ring shape will be described in detail as a representative example.
In the following, the case where the magnets 11 are arranged side by side in a ring while adjacent ones of the plurality of permanent magnets 11a, 11b, 11c.

  The permanent magnets 11a, 11b, 11c,... Of the magnet arrangement structure 10 are arranged side by side in a ring shape. Moreover, these permanent magnets 11a, 11b, 11c... Are arranged so that different magnetic poles are alternately arranged along the inner surface. Specifically, in a state where a plurality of permanent magnets 11a, 11b, 11c... Are arranged along the circumferential direction of the spool shaft 3 so as to supply a magnetic force from the radial direction of the spool shaft 3, each permanent magnet 11a, Are arranged such that different magnetic poles are alternately arranged along the circumferential direction of the spool shaft 3. That is, different magnetic poles are arranged alternately along the inner peripheral surface of the plurality of annularly formed permanent magnets 11a, 11b, 11c,.

The number, shape, size, etc. of the permanent magnets 11a, 11b, 11c... Are not particularly limited.
For example, as long as the permanent magnets 11a, 11b, 11c,... Can be arranged as described above, rod-shaped, plate-shaped, and rectangular shapes can be employed. The cross-sectional shape may be various shapes such as a rectangular shape, a rectangular shape, a fan shape, a circular shape, and a rod shape.

  In addition, a fan-shaped cross section is a general shape in which one side is an arc shape and two sides are formed to the same length, and the bottom side of a truncated isosceles triangle whose tip is cut off is formed in an arc shape. This is a concept that includes various shapes.

  Hereinafter, the operation and effect when four permanent magnets having a columnar shape and a fan shape in a sectional view are used as the permanent magnets of the magnet 11 will be specifically described.

As shown in FIG. 3 or FIG. 4, the magnet 11 of the magnet arrangement structure 10 is formed by annularly combining four permanent magnets 11 a, 11 b, 11 c, and 11 d having a fan-shaped cross section. At this time, as shown in FIG. 3, the combined annular magnet 11 has a space 10h in which the cylindrical portion 3b can be arranged so as to overlap with the inside.
Note that the inner diameter of the internal space 10h may be any size as long as the cylindrical portion 3b of the spool shaft 3 can be inserted as described above, and is formed to be, for example, the same as or slightly larger than the outer diameter of the cylindrical portion 3b. Have been.

As shown in FIG. 3 or FIG. 4, the magnet 11 is mounted in a state where the magnet arrangement structure 10 is mounted such that the centers of the four permanent magnets 11 a, 11 b, 11 c, 11 d substantially coincide with the center axis of the spool shaft 3. The permanent magnets are arranged so as to be rotationally symmetric.
Specifically, the permanent magnet 11a and the permanent magnet 11c are arranged so as to face the center axis of the spool shaft 3, and the permanent magnet 11b and the permanent magnet 11d are arranged so as to face the center axis of the spool shaft 3. At this time, each of the opposed permanent magnets has a pole located inside (i.e., a pole located at an inner edge of the spool shaft 3 side; in FIGS. 3 and 4, an inner circumference forming an internal space 10 h). (Poles located on the plane) are the same. For example, as shown in FIGS. 3 and 4, the permanent magnets 11a and 11c are arranged so as to have N poles, and the permanent magnets 11b and 11d are arranged so as to have S poles.

  Then, each of the permanent magnets 11a, 11b, 11c, 11d of the magnet 11 becomes, for example, an S-pole, an N-pole, an S-pole, and an N-pole at the inner end along the inner peripheral surface, and along the outer peripheral surface outside the inner pole. At the outer end, they can be arranged so as to have opposite N pole, S pole, N pole and S pole. That is, the permanent magnets 11a, 11b, 11c, and 11d of the magnet 11 are arranged such that the S pole, the N pole, the S pole, and the magnetic pole different from the N pole are arranged along the circumferential direction of the spool shaft 3 on the inner peripheral surface. You. At this time, as shown in FIG. 4, a plurality of magnetic force lines ML from the N pole to the S pole can be formed inside each of the permanent magnets 11a, 11b, 11c and 11d of the magnet 11.

  Accordingly, as shown in FIG. 4, if the shaft 3a of the spool shaft 3 rotates (counterclockwise rotation in FIG. 4) in the state where the magnet arrangement structure 10 is arranged at a predetermined position, the cylinder An eddy current is generated on the surface of the portion 3b (the outer surface of the portion facing the magnet 11 in FIG. 4) by the action of the permanent magnets 11a, 11b, 11c, 11d of the magnet 11.

As shown in FIG. 4, when the poles facing the cylindrical portion 3b of the permanent magnets 11a and 11c are N-poles, N-poles and S-poles are alternately generated in the cylindrical portion 3b. In this case, the location where the permanent magnets 11a and 11c approach is the N pole, and the location where the permanent magnets 11a and 11c are away from the permanent magnets 11a and 11c, the eddy current is reversed and becomes the S pole. Conversely, when the pole facing the cylindrical portion 3b of the permanent magnets 11b and 11d is the S pole, the location where the permanent magnets 11b and 11d approach is the S pole, and the location where the permanent magnets 11b and 11d move away is the vortex. The current is inverted and becomes the N pole. At this time, a force for attracting both is generated between the cylindrical portion 3b and the permanent magnet of the magnet 11.
That is, if the shaft 3a of the spool shaft 3 rotates as described above, an attractive force can be generated between the cylindrical portion 3b and the permanent magnet of the magnet 11, so that the braking force against the rotation of the cylindrical portion 3b can be generated. (Braking force) can be generated (see a clockwise black arrow described near the cylindrical portion 3b in FIG. 4).

(How to adjust the braking force)
As shown in FIG. 5, the braking force (braking force) is determined by the magnetic strength of the permanent magnet of the magnet 11 of the magnet arrangement structure 10 and the overlap between the permanent magnet of the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b. It can be adjusted appropriately according to the amount L (that is, the amount L where the permanent magnet of the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b overlap) and the like.

For example, as described above, if the plurality of permanent magnets 11a, 11b,... Are arranged so that different magnetic poles are alternately arranged along the inner peripheral surface of the magnet 11, toward the inside of the magnet arrangement structure 10, Since a plurality of lines of magnetic force ML can be generated (see FIG. 4), the braking force (that is, the braking force) can be appropriately exerted, which is preferable.
The method of adjusting the overlapping amount L of the magnet 11 and the cylindrical portion 3b of the magnet arrangement structure 10 will be described later in detail.

As shown in FIG. 4B, the annular magnet 11 is formed by using the plurality of permanent magnets 11a, 11b,... As described above, and different magnetic poles are alternately arranged along the inner peripheral surface. In the case of disposition, a configuration in which a non-magnetic member 14 formed of a material that does not take on magnetism or does not easily take on magnetism may be provided between the adjacent permanent magnets 11a, 11b. As a material of the non-magnetic member 14, for example, a non-magnetic material such as plastic or rubber can be adopted.
With this structure, it is possible to suppress the magnetic lines of force generated between the adjacent permanent magnets 11a, 11b,. In this case, the lines of magnetic force ML inward from the inner peripheral surface of the annularly formed magnet 11 of the magnet arrangement structure 10 (that is, the lines of magnetic force ML generated toward the spool shaft 3) can be increased (FIG. 4). , A counterclockwise dashed arrow described near the inside of the magnet 11 of the magnet arrangement structure 10)).

(Yoke 12)
The magnet arrangement structure 10 may include a ring-shaped yoke portion 12 for holding a magnet 11 having a function of generating magnetism.
The yoke part 12 is a member for holding the magnet 11 so that the magnet 11 of the magnet arrangement structure 10 is arranged at a predetermined position. Specifically, the yoke part 12 is a ring-shaped member arranged along the outer periphery of the magnet arrangement structure 10, and holds the magnet 11 described above inside. That is, the yoke portion 12 is not particularly limited as long as it can hold the magnet 11.
For example, as shown in FIGS. 2 to 4, the plurality of permanent magnets 11 a, 11 b,. Then, in a state where the magnet arrangement structure 10 is arranged at a predetermined position, an annular magnet 11 is formed along the circumferential direction of the spool shaft 3 so as to be rotationally symmetric about the spool shaft 3. By providing the yoke portion 12 formed in a ring shape so as to cover the outer peripheral surface of the annular magnet 11, the annular structure of the plurality of magnets 11 can be appropriately maintained.

The yoke portion 12 is formed of a magnetic material.
For example, a yoke (yoke) generally used to increase the magnetic force can be employed.

For this reason, for example, as shown in FIGS. 2 to 4, when the yoke portion 12 is provided along the outer peripheral surface of the annularly arranged magnet 11, the position of the yoke portion 12 is outside the magnet 11 of the magnet arrangement structure 10. Since the magnetic lines of force coming out of the N pole return to the S pole via the yoke portion 12, diffusion of the magnetic lines of force can be suppressed.
Then, the lines of magnetic force ML generated toward the inside of the magnet 11 of the magnet arrangement structure 10 can be increased.
In addition, since the diffusion of the magnetic field lines to the outside of the magnet arrangement structure 10 can be suppressed, it is possible to reduce the surroundings based on the magnetic field lines.

The size of the magnet arrangement structure 10 is not particularly limited as described above. However, as shown in FIG. 2, the magnet arrangement structure 10 is preferably formed to have a size that can be inserted into the bobbin trunk 4 a of the bobbin 4. preferable. Then, as shown in FIG. 2, it is preferable that the cylindrical portion 3 b is formed such that the edge is located inside the side edge of the bobbin trunk 4 a of the bobbin 4.
In this case, since the electromagnetic brake of the bait reel 1 can be provided inside the bobbin trunk 4a of the bobbin 4, the lateral width of the bait reel 1 (the size in the left-right direction in FIG. 1) can be reduced as much as possible. .
Then, the reel body can be reduced in size (compacted), and can be formed in a size that can be operated with one hand, so that operability can be further improved.

(Cover part 13)
Further, as shown in FIG. 2 or 3, the magnet arrangement structure 10 may include a cover 13 that covers the surface.
The cover 13 is not particularly limited as long as it is provided so as to cover the surface of the magnet arrangement structure 10. For example, the magnet arrangement structure 10 may be provided only on the outer peripheral surface viewed from the radial direction, may be provided only on the end surface viewed from the axial direction, or may be surrounded by the inner end surfaces of the plurality of magnets 11. May be provided only on the inner wall surface of the internal space 10h formed in the inner space.
When the cover 13 covers the inner wall surface that forms the space 10h inside the magnet arrangement structure 10, when the metal piece or the like enters the gap between the magnet arrangement structure 10 and the cylindrical portion 3b, it is easily removed. . On the other hand, when the inner wall surface of the internal space 10h of the magnet arrangement structure 10 is not covered with the cover part 13, the outer peripheral surface of the magnet arrangement structure 10 is only covered with the cover part 13, so that the cover part 13 is provided. This has the advantage that the magnet arrangement structure 10 can be easily formed.

  The surface of the magnet arrangement structure 10 is a concept that includes not only the outer peripheral surface of the magnet arrangement structure 10 but also the axial end surface and the inner wall surface of the internal space 10h. That is, the cover portion 13 may be provided so as to cover the entire outer peripheral surface, the end surface, and the inner wall surface of the magnet arrangement structure 10, or may be provided only on a part thereof.

(Movement adjustment mechanism of magnet arrangement structure 10 using a cam mechanism)
If the magnet arrangement structure 10 of the bait reel 1 is formed so that the inner diameter is larger than the outer diameter of the cylindrical portion 3b, the magnet arrangement structure 10 can be moved along the axial direction of the spool shaft 3, so that the cylindrical portion 3b Can be adjusted.

The movement adjustment mechanism of the magnet arrangement structure 10 using the cam mechanism includes a magnet holding unit 14 connected to the magnet arrangement structure 10 and a brake adjustment unit 20.
As shown in FIG. 2, a base end of a magnet holding portion 14 for holding the magnet arrangement structure 10 is connected to an end of the magnet arrangement structure 10 opposite to the handle H side.
As shown in FIG. 2, the magnet holding portion 14 is a cylindrical member, and a cam shaft 14a is connected near the distal end (near the left frame f in FIG. 1). The cam shaft 14a is a rod-shaped member, and the base end is connected to the magnet holding member 14 as described above. A brake adjusting section 20 is provided in the direction of the tip of the cam shaft 14a.

  As shown in FIGS. 2, 6, and 7, the brake adjustment unit 20 includes an adjustment screw 21 rotatably provided and a fixing unit for fixing and holding the adjustment screw 21 to a frame f or the like. 22.

As shown in FIGS. 2, 6, and 7, a cam groove 20g is formed on a side surface of the adjusting screw 21. The cam groove 20g is a groove into which the tip of the cam shaft 14a is inserted, and is formed so as to intersect the circumferential direction of the adjusting screw 21.
For example, as shown in FIG. 6A, in a plan view of the brake adjustment unit 20, the cam shaft 14 a is disposed on the side surface of the adjustment screw 21 from the front side to the back side (in FIG. 6A, from the left side to the right side of the drawing). It is formed so as to be inclined toward.

The depth of the cam groove 20g is not particularly limited as long as the tip of the cam shaft 14a can be inserted. For example, it may be formed in a groove with a bottom, or may be formed as a groove communicating the front and back of the side wall of the adjustment screw 21.
Further, the shape of the cam groove 20g may be, for example, a linear shape as shown in FIG. 6A, but is not limited to such a shape. Good.
On the other hand, as shown in FIG. 2, on the inner surface of the cylindrical magnet holding portion 14, a projecting portion 14b projecting inward is formed. The magnet arrangement structure movement control member 15 is arranged inside the cylindrical magnet holding unit 14. On the side surface of the magnet arrangement structure movement control member 15, a flange 15a with which the projection 14b of the magnet holding portion 14 is engaged is formed at a position located outside the projection 14b of the magnet holding portion 14. .

  Since the structure is as described above, if the inner diameter of the magnet arrangement structure 10 is formed to be larger than the outer diameter of the cylindrical portion 3b as described above, the magnet arrangement structure 10 is Can be moved as follows.

As shown in FIGS. 5A and 7A, in a state where the tip of the cam groove 20g is located near the front wall of the adjusting screw 21, the cam shaft 14a is positioned at the tip of the cam groove 20g. To place. At this time, the magnet arrangement structure 10 is arranged so as to surround a part of the cylindrical part 3b (that is, a state in which the part of the cylindrical part 3b is inserted into the internal space 10h of the magnet arrangement structure 10). Are arranged so that it becomes).
As shown in FIG. 5A, the overlapping amount of the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b at this time is defined as L1.

  In such a state, the adjustment screw 21 is rotated clockwise in a front view (in the direction of the arrow described near the front wall of the adjustment screw 21 in FIGS. 5A and 7A, and in FIG. 6B). Clockwise relative to the page). At this time, since the cam shaft 14a abuts on the cam groove 20g and interferes with each other, the cam shaft 14a moves along the cam groove 20g from the distal end to the base end of the cam groove 20g.

Then, as the cam shaft 14a moves, the magnet holding member 14 to which the cam shaft 14a is connected moves (moves from the left side to the right side in FIG. 5). Then, the magnet arrangement structure 10 connected to the base end of the magnet holding member 14 moves along the axial direction of the spool shaft 3 (moves from the left side to the right side in FIG. 5).
That is, the movement of the magnet arrangement structure 10 along the axial direction of the spool shaft 3 is guided by the cam mechanism.

  As shown in FIG. 5B, the overlapping amount of the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b at this time is L2.

Therefore, when it is desired to increase the braking force described above, the adjusting screw 21 is turned many times, and the amount of overlap between the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b (that is, within the internal space 10h of the magnet arrangement structure 10). If the adjustment is made to increase the amount of the cylindrical portion 3b to be inserted, the braking force of the electromagnetic brake can be increased (see FIG. 5B).
On the other hand, when it is desired to reduce the braking force, the adjustment screw 21 is turned in the opposite direction to the above, and the overlapping amount of the magnet 11 of the magnet arrangement structure 10 and the cylindrical portion 3b (that is, the internal space 10h of the magnet arrangement structure 10) The braking force of the electromagnetic brake can be weakened by adjusting the amount of the cylindrical portion 3b to be inserted thereinto (see FIG. 5A).

For example, if the user has a high casting speed, as shown in FIG. 5B, the adjusting screw 21 is turned to move the magnet arrangement structure 10 along the axial direction of the spool shaft 3 so that the magnet arrangement can be performed. Casting is performed in a state where the entire cylindrical portion 3b is placed in the internal space 10h of the structure 10. Then, even if the casting speed is high, backlash can be prevented, and a lure or the like can be cast at an appropriate flight distance.
On the other hand, if the beginner has a slow casting speed, the adjusting screw 21 is turned to move the magnet arrangement structure 10 along the axial direction of the spool shaft 3, contrary to the former, as shown in FIG. The casting is performed in a state where the overlap with the cylindrical portion 3b is reduced. Then, the casting speed is slow, backlash can be prevented, and a lure or the like can be cast to an appropriate flight distance.

  That is, by turning the adjusting screw 21 of the brake adjusting unit 20, the insertion amount of the cylindrical portion 3b to be inserted into the magnet arrangement structure 10 can be adjusted, so that only a simple operation of adjusting the adjusting screw 21 is required. The braking force can be easily adjusted. In other words, if the bait reel 1 is used, it can be used regardless of the skill level of the user, and when casting is performed, the backlash can be prevented and the rotating performance suitable for the user can be exhibited. .

  In particular, since the movement of the magnet arrangement structure 10 along the axial direction of the pool shaft 3 is guided by the cam mechanism, a slight movement of the magnet arrangement structure 10 can be appropriately performed. Therefore, the adjustment of the braking force according to the skill and preference of the user can be performed more easily and appropriately.

(Material of spool part 2)
The material of the spool unit 2 is not particularly limited as long as it is used for a general reel. For example, when the material of the bobbin 4 of the spool portion 2 is made of a titanium alloy, an aluminum alloy, or the like, durability can be improved while ensuring strength.

If the material of the shaft 3a of the spool portion 2 is made of stainless steel as described above, the strength can be ensured while having water resistance.
Further, the shaft 3a and the cylindrical portion 3b may be formed integrally, but if they are formed separately, the materials of the shaft 3a and the cylindrical portion 3b can be changed. For example, as described above, if the shaft 3a is formed of stainless steel and the cylindrical portion 3b is formed of aluminum, the inertia weight can be reduced while maintaining high strength. Then, since the durability and the moment of inertia can be further reduced, the rotational performance of the bobbin 4 of the spool portion 2 can be further improved, so that the bait reel 1 having both durability and operability can be obtained. There is.

  The bait reel of the present invention can be used irrespective of the skill of the user, and is suitable as a reel that can exhibit rotating performance suitable for the user while preventing backlash when performing casting. I have.
