Description

[Detailed Description of the Invention] The present invention relates to an improvement of a fishing line buckling prevention device using a magnet.

No particular consideration has been given to the way the inner magnetic body and outer magnetic body are attached to the reel side plate in conventional anti-buckling devices of this type, making it particularly difficult to install the magnetic body in a lightweight and accurate manner, and in manufacturing and assembly. This is troublesome, and furthermore, it increases the weight of the reel, and if the reel hits a rock or falls, the impact may cause the magnetic pole ring to lose its accuracy or shift position.

The present invention is an attempt to improve these deficiencies. A dish-shaped holding case is fixed to the inner frame of the reel side plate that does not house the drive mechanism, and the holding case is inserted into the shaft cylinder protruding from the inner bottom of the holding case. The tip of the spool shaft to which the spool is fixed is supported via a bearing, and a conductive ring made of a non-magnetic material is provided protruding from one side of the spool into the holding case, with a gap provided on the circumferential surface of the conductive ring. In a double-bearing type reel in which a magnet is arranged and the spool is braked by an eddy current action generated in a conductive ring by rotation of the spool, the magnet is formed into a disk shape, and the disk-shaped magnet is synthesized. The magnetic poles are fitted in the plurality of radial notch grooves formed in the resin ring body in a radial direction and the magnetic poles of adjacent magnets are alternately reversed, and one side of the disc-shaped magnet is made of a magnetic material. The gist is that a yoke is fixed and the synthetic resin ring is attached to the holding case.

An embodiment of the present invention will be described with reference to the drawings. Reel side plates 1 and 2 of a double bearing type reel are respectively formed of outer plates 3 and 3' and inner frames 4 and 4'. A handle 5 and a drive gear mechanism (not shown) are provided to rotate a spool shaft 7 on which a spool 6 is provided, and a dish-shaped holding case 8 is fitted and fixed to the inner frame 4' of the reel side plate 2. The tip of the spool shaft 7 is supported through a bearing 10 in a shaft cylinder 9 protruding from the center of the holding case 8.

An annular yoke 12 made of a magnetic material and having a synthetic resin ring 11 fitted on the outer peripheral surface of the shaft cylinder 9 of the holding case 8 is fitted and fixed. A plurality of notched grooves are formed in the notched grooves, and disk magnets 13 having magnetic poles in the radial direction are formed in the notched grooves.
are fitted and fixed alternately with their magnetic poles in opposite directions, and on one side of the spool 6 is a conductive ring made of a non-magnetic material such as aluminum or copper located outside the synthetic resin ring 11. 14 is provided protrudingly.

Further, on the inner circumferential surface of the rotary cylinder 15 rotatably provided on the peripheral side of the holding case 8, a magnetic material is placed outside the conductive ring 14 and has a synthetic resin ring 16 fixed inside. The annular yoke 17 is fixed, and a plurality of notched grooves are formed at equal intervals from one end on the peripheral surface of the synthetic resin ring body 16, and different poles of the magnets 13 face each other in the notched grooves in the radial direction. Disc-shaped magnets 18 having magnetic poles are fitted and fixed with their magnetic poles alternately opposite in direction, and the meshing teeth 19 formed on the outer circumferential surface of the rotating cylinder 15 are connected to the notches 20 provided in the holding case 8. The magnet 1 of the synthetic resin ring body 16 is engaged with the gear 22 of the operating knob 21 exposed from the outer plate 3' and pivoted on the outer plate 3', and the operating knob 21 rotates the rotary cylinder 15.
The structure is such that the opposing position of the synthetic resin ring body 11 of No. 8 with respect to the magnet 13 can be changed.

A fishing line-preventing edge 23 that fits into the flange portion 6' of the spool 6 is integrally formed in the fitting portion of the holding case 8 with respect to the inner frame 4'.

Since the embodiment of the present invention is constructed as described above, when the synthetic alicyclic body 16 is rotated via the gear 22 and the rotation tube 15 by rotating the operating handle 21, the rotation angle corresponds to the rotation angle. magnet 18 and magnet 13
The air gap magnetic flux density changes to change the eddy current generated in the conductive ring 14 and adjust the braking force against the eddy current to prevent the fishing line from collapsing.

In the above embodiment, the outer synthetic resin ring body 16 is rotated, but it may be fixed and the inner synthetic resin ring body 11 is rotated. is made of ABS resin,
As the disc-shaped magnets 13 and 18, it is preferable to use rare earth cobalt magnets, ferrite magnets, etc. coated with urethane or epoxy resin, and the holding case can also be formed integrally with the inner frame.

In this invention, a holding case is fixed to the inner frame of the reel side plate that does not house the drive mechanism, and the tip of the spool shaft is supported via a bearing in the shaft cylinder protruding from the inner bottom of the holding case. In a back crushing device in which a conductive ring made of a non-magnetic material is protruded from the side into the holding case, and a magnet is provided around the conductive ring to brake the spool by means of an eddy current, it is particularly preferable that the magnet be shaped like a disc. By fitting and fixing this into the notched groove of the synthetic resin ring body so that the magnetic poles are alternately reversed in the radial direction, the lines of magnetic force are focused in the radial direction, improving the eddy current generation efficiency and creating an eddy current generator. It is possible to reduce the weight of the reel and prevent an increase in the weight of the reel as much as possible, and it is also easy to position the magnets during assembly, allowing them to be placed accurately and stably at equal intervals on the yoke. Since it can be used, manufacturing and assembling magnetic materials is also extremely easy.

In addition, in this invention, the bearing part of the spool shaft and the crush prevention device are housed and supported in the holding case, and the disc-shaped magnet is fitted and fixed in the notch groove of the synthetic resin ring body, so the reel will not hit the rock. , the shock caused by a fall is not directly transmitted to these parts, so there is no risk of the spool shaft support part or eddy current generator becoming inaccurate or misaligned, and is an excellent product that can easily and reliably prevent the fishing line from collapsing. It has characteristics and practicality.
