[0029] FIGS. 1A-4B illustrate a magnetic braking system, in accordance with some embodiments. Referring to FIG. 1A, in some embodiments, the magnetic braking system includes a rotor 110 and a slider device 120. The rotor 110 is attached to a bearing which is further attached to a fishing reel. The rotor 110 includes a plurality of spaced-apart holes, and a plurality of magnets 112. In some embodiments, each of the plurality of holes is located at a same distance from each other in a circular manner on the rotor 110. Each of the plurality of magnets 112 is located in a respective member of the plurality of holes. In some embodiments, a first end of each of the plurality of magnets is positioned in a common plane. The common plane is perpendicular to an axis of rotation of a spool. FIG. 1A illustrates the magnetic braking system when the rotor 110 and the slider device 120 are in a proximate distance from each other, i.e., at engaged position (discussed below). FIG. 1B illustrates the magnetic braking system when the rotor 110 and the slider device 120 are farther apart from each other, i.e., at released position (discussed below).

[0030] Referring to FIG. 2, the slider device 120 includes a three-layer structure stacked on each other: a first sheet 210, a second 1 sheet 220 and a third sheet 230. The first sheet 210 is substantially larger than the second sheet 220 and the third sheet 230. The second sheet 220 is over the first sheet 210. The second sheet 220 and the third sheet 230 are substantially a same size. The third sheet 230 is over the second sheet 220. Each of the second sheet 220 and the third sheet 230 includes a magnet 220a and 220a in a hole, similar to the rotor 110. The three-layer sheets of the slider device 120 are attached together using a cylinder 240. In some embodiments, the first sheet 210 and the second sheet 220 are in contact with each other. In some embodiments, the sheets 210, 220 and 230 and the cylinder are made of one of: a , an alloy, a polymer, or any other suitable materials.

[0031] The second sheet 220 and the third sheet 230 are separate from each other, thus, creating a gap 250. The gap 250 is so designed that a size of the gap 250 is larger than a thickness of the rotor 110. This enables the rotor 110 to be located between the second sheet 220 and the third sheet 230 when braking, as illustrated in FIG. 3. When the rotor 110 is in the gap 250, the interactions between the plurality of magnets of the rotor 110 and the magnets of the second and the third sheet 220a and 230a cause the rotor 110 and subsequently the reel to stop from rotating. In other words, the magnetic force between the magnets of the rotor and the slider device stops the rotor from rotating when the slider device is pushed to engage with the rotor.

[0032] FIGS. 4A and 4B illustrate the magnetic braking system in accordance with some embodiments. The rotor 110 and the slider device 120 are configured to brake the fishing reel once they are engaged. To that end, the slider device 120 is so designed to move, i.e., slide, between a first position, i.e., a released position, and a second position, i.e., an engaged position. At the released position, the slider device 120 is farther apart from a center of the rotor 110, while at engaged position, the slider device 120 is closer to the center of the rotor 110. That is, at the engaged position, the plurality of the magnets of the rotor 110 are in a proximate distance of magnets of the slider device 120. FIG. 4A illustrates the magnetic braking system when the rotor 110 and the slider device 120 are in a proximate distance from each other, i.e., at the engaged position. FIG. 4B illustrates the magnetic braking system when the rotor 110 and the slider device 120 are farther apart from each other, i.e., at the released position.

[0033] In some embodiments, the sheets 210, 220 and 230 are attached to each other by bolts and nuts.

[0034] In some embodiments, the rotor 110 includes a hole 410 in a center of the rotor 110. The hole 410 is configured to attach the rotor 110 to the fishing reel.

[0035] In some embodiments, the magnets are cylindrical-shaped. The cylindrical magnets are so positioned that if a north pole end of a first magnet is facing the line spool, south ends of two adjacent magnets of the first magnet are facing the line spool, and vice versa. It is possible to change the magnetic force required for braking by changing the spacing between the magnets and/or increasing/decreasing the strength of one or more magnets. For example, in some embodiments, a user may increase the space between one or more of the magnets when the required force for braking the fishing reel in a certain situation is less than the force produced between existing magnets at a current distance apart.

[0036] In some embodiments, the fishing reel is a fly reel. In some embodiments, the fishing reel is a centrepin reel.

[0037] In some embodiments, the magnets have a same size. In some embodiments, magnets of different sizes can be used. In some embodiments, the rotor is made of a magnetically conductive material. In some embodiments, the rotor is made of a non-magnetic material.

[0038] Using disclosed magnetic braking system for fishing reels eliminates using clicker systems that are usually spring-loaded on with touching parts that can wear and make noise.

[0039] In some embodiments, the system for magnetic braking in fishing reels includes a fishing reel including a spool, a lever, a rotor, and a slider device. The rotor includes a plurality of spaced-apart holes located at substantially a same distance from each other in a circular manner on the rotor, and a plurality of magnets located in the plurality of holes. A first end of each of the plurality of magnets is positioned in a common plane perpendicular to an axis of rotation of the spool. The slider device includes a first sheet, a second sheet over the first sheet and a third sheet over the second sheet. Each of the second sheet and the third sheet include a magnet in a hole. The slider device is movable between a first position and a second position, where the first position is farther apart from a center of the rotor. There is a gap between the second sheet and the third sheet, where the gap is substantially larger than the thickness of the rotor. The slider device is movable between a first position and a second position, the first position is farther apart from a center of the rotor. The interactions between the one or more magnets of the movable slider device and the plurality of the magnets of the rotor cause the rotor to brake when the movable slider device is at the second position and the rotor is in the gap.

However, the illustrative discussions above are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in view of the above teachings.
