Description

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

In addition to a method that uses centrifugal force, a method that uses magnets has recently been known as a means for preventing the fishing line from becoming frayed due to over-rotation of the spool when the line is fed out of a fishing reel.

In the former, the braking force is not proportional to the spool rotation speed,
The braking force increases noticeably in the high rotation range, and there is a drawback that the braking force adjustment requires replacing the weight with a weight of different weight each time, and the latter adjusts the braking force in proportion to the spool rotation speed. However, it has the drawback of increasing the weight and size of the device because a strong magnet must be provided to sufficiently compensate for the high rotation range that requires a large braking force.

The present invention improves these deficiencies by using both of them in combination. A non-magnetic conductive member is provided on one side of the spool, and a magnet facing the non-magnetic conductive member with a small gap is adjusted to the reel side plate. a support rod protruding in the radial direction on the other side of the spool, in which a weight is slidably fitted;
The gist is that a brake ring is formed on the reel side plate at the outer end of the support rod.

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 within a shaft cylinder 9 protruding from the center of the holding case 8 via a pairing 10.

An inner magnetic pole ring 13 consisting of an annular magnet 11 having an arbitrary number of poles and an annular yoke 12 made of a magnetic material fitted to the inner circumferential surface of the annular magnet 11 is fixed to the outside of the shaft cylinder 9 of the holding case 8. A conductive ring body 14 made of a non-magnetic material such as aluminum or copper is protruded from one side of the spool 6 so as to be located outside the inner magnetic pole ring body 13 .

Further, on the inner circumferential surface of the rotary cylinder 15 rotatably provided in the holding case 8, there are an annular magnet 16 located outside the conductive ring body 14 and having an arbitrary number of poles, and a magnetic magnet 16 fitted on the outer circumferential surface thereof. An outer magnetic pole ring 18 made of an annular yoke 17 of material is fixed, and the rotating tube 15
The meshing teeth 19 formed on the outer peripheral surface of the holding case 8
It meshes with the gear 22 of the operating knob 21 which is exposed through the notch 20 provided in the outer plate 3' and is pivotally supported by the outer plate 3', and the rotation of the operating knob 21 rotates the rotating tube 15 to rotate the outer magnetic pole ring. It is configured such that the position of the body 18 facing the inner magnetic pole ring body 13 can be displaced.

On the side of the reel side plate 1 of the spool shaft 7, a support rod 2 is perpendicular to the spool shaft 7 and has a weight 23 slidably fitted therein.
A brake ring 25 is fixed to the inner frame 4 at the outer end of the support rod 24.

Since the embodiment of the present invention is constructed as described above, when the fishing line is paid out and the spool 6 rotates, an eddy current is generated in the conductive ring 14 in proportion to the number of rotations, and the spool 6 is braked and at the same time becomes heavy. The weight 23 also slides the support rod 24 outward by centrifugal force and collides with the brake ring 25 to brake excessive rotation of the spool 6.

However, in this case, when the operating handle 21 rotates the outer magnetic pole ring 18 via the rotation cylinder 15 and changes its opposing position with respect to the inner magnetic pole ring 13, the magnetic flux between the two changes depending on the rotation angle. Since the density changes, the eddy current generated in the conductive ring 14 also changes, and the braking force can be adjusted to be strong or weak.

In the above embodiment, the support rod 24 is provided on the spool shaft 7 on the reel side plate 1 side, but it can also be provided on the conductive ring 14 on the reel side plate 2 side as shown in Figure 4, and the adjustment of the magnetic flux density by the inner and outer magnetic pole rings 13, 18 can be performed by axial movement rather than rotation, and further, the magnets used for these do not necessarily have to be annular but can be provided intermittently on the yoke.

The present invention prevents over-rotation of the spool of a double-bearing type reel by both a braking action by eddy current generated in a non-magnetic conductive member by a magnet and a braking action by centrifugal force against a brake ring of a weight. Since the braking force generated by the current is adjustable, over-rotation at low spool rotations can be compensated for by the centrifugal force brake, which has a small braking force, with a magnetic brake, which has a large braking force, and over-rotation at high spool rotations can be prevented by centrifugal force. To make the brake exert its power and to prevent the increase in weight and size of the reel itself, which are the defects of the magnet brake, so that both deficiencies can be mutually supplemented, and furthermore, the braking force can be adjusted with the magnet brake. It has excellent features and practicality that can be adjusted at will.
