Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a backlash preventing device for a fishing reel, especially a double bearing type reel.

[0002]

2. Description of the Related Art In a dual-bearing type reel for fishing, a dish-shaped conductive ring member is fixed to a spool shaft having a spool rotatably supported on the reel unit, and the reel unit is opposed to the conductive ring member. A backlash device using a magnet, in which an eddy current is generated in a conductive ring body by a magnet installed in the above to brake a spool, is known from Japanese Utility Model Publication No. 63-32632 and Japanese Utility Model Publication No. 2-33672. .

[0003]

The above-mentioned conventional conductive ring body is formed of an aluminum material or a copper material in a cylindrical shape having a bottom and is fixed to the spool shaft. However, an eddy current is generated by a magnet to perform a braking action. The only part to do is the cylindrical part facing the magnet, and the bottomed part only functions as a support member for fixing to the spool shaft, and even the bottomed part that is only this support member is made of aluminum or copper material. At the time of forming, the entire spool including the spool shaft becomes heavy and the moment of inertia becomes large, so that the braking efficiency of the spool is lowered and this weighting has a defect that the casting function is also lowered. In view of these circumstances, an object of the present invention is to provide a backlash preventing device for a fishing reel that reduces the weight of the entire spool due to the conductive ring body and improves braking efficiency and casting function. It is a thing.

[0004]

In order to achieve the above-mentioned object, the present invention has a conductive ring member fixed to a spool shaft rotatably supported by a reel unit, and a conductive ring member is provided with a magnet installed to face the conductive ring member. In a fishing reel in which an eddy current is generated in a body to brake a spool, a support member having a specific gravity smaller than that of a conductive ring body is fixed to the spool shaft, and a cylindrical conductive ring is provided on an outer peripheral portion of the support member. The body is fixed, and when the tubular conductive ring body is formed of an aluminum material, the support member is an ABS whose specific gravity is lighter than that of the aluminum member.
When using a synthetic resin such as resin, nylon, polyacetal, etc., and forming the cylindrical conductive ring with a copper material, aluminum having a lighter specific gravity than the copper material can be used as the supporting member, but the former Is preferable, and by forming a deep-bottomed recess on both sides of the fishing line winding body of the spool in order to provide the supporting member on the spool shaft in the fishing line winding body of the spool, the spool can be made further lightweight. The amount of protrusion of the cylindrical conductive ring body from the spool to the side is also reduced, and the axial size of the backlash prevention device can be reduced.

[0005]

According to the present invention, since the supporting member for fixing the cylindrical conductive ring body to the spool shaft is made of a material having a lower specific gravity than the conductive ring body, the weight of the entire spool including the spool shaft is reduced. Therefore, the moment of inertia of the spool becomes small, the braking action at the time of backlash of the spool is efficiently performed, and the fishing line releasing action can be smoothly performed at the time of casting.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.
A spool shaft 4 supported in a well-known manner between both side plates 2 and 3 of a reel body 1 of a dual bearing type reel has deep-bottomed recesses 5'and 5'formed on both sides in the fishing line winding body. 5 is fixed, and a supporting member 6 made of aluminum, ABS resin, nylon, polyacetal resin, or the like is fixed in the recess 5'on the side plate 3 side of the spool shaft 4 so as to rotate integrally. Copper toward the side slope on the outer periphery of the member 6,
A cylindrical conductive ring body 7 made of an aluminum material is fixed by adhesion, press fitting, or the like, and in particular, the support member 6 is formed of a material having a lower specific gravity than the conductive ring body 7.

Therefore, when the conductive ring member 7 is made of, for example, an aluminum material, the support member 6 is made of ABS resin, nylon, or poacetal resin having a lighter specific gravity than that of the support member 6.
When is made of a copper material, the support member 6 is made of an aluminum material. On the other hand, a magnet 8 is installed on the side plate 3 so as to face the inner and outer peripheral surfaces of the cylindrical conductive ring body 7.
Thus, a backlash preventive device 9 for braking the spool 5 by generating an eddy current in the rotating conductive ring body 7 is configured.

The central surface of the fishing line winding body of the spool 5 is provided with notches 10 and 10 in the circumferential direction, and a small hole 11 formed between the notches 10 and 10 and the small hole 11.
Insertion hole 1 in which the cutout recesses 10 and 10 are communicated with each other.
2 and 12 are provided, and a fishing line having a knot formed at the end is inserted into the insertion hole 12 to lock the knot, or as shown in FIG. 5, it has a locking projection 14 that locks the fishing line 13. The elastic pin 15 is formed so that the fishing line 13 can be locked by inserting and locking the elastic pin 15 in the insertion hole 12. When the base end of the fishing line is locked to the spool 5 in this way, even the slippery fishing line 13 can be locked by the spool 5 It can be securely locked on the winding body without slipping.

The embodiment shown in FIGS. 6 to 9 has a spool 5
A support member 6 having a cylindrical conductive ring 7 is fixed to a spool shaft 4 on the outer side of the side slope 3 side, and a notch recess 1 having a locking step 17 at the center of the winding body of the spool 5.
8 is formed, and the fishing line locking tool 21 having the locking portion 19 of the locking stepped portion 17 and the insertion hole 20 is detachably fitted and engaged in the notch concave portion 18, and the fishing line 13 having a knot is inserted. It is formed so that it can be locked in the hole 20.

[0010]

According to the present invention, a cylindrical conductive ring having a large specific gravity is fixedly supported on a spool shaft by a supporting member having a small specific gravity to reduce the weight of the entire spool including the spool shaft and reduce its inertia moment. The spool braking efficiency by the eddy current between the magnet and the conductive ring is improved when the spool is backlashed, and the weight of the entire spool is reduced, and the fishing line casting operation can be smoothly performed.

Further, in the present invention, when the support member is provided on the spool shaft in the fishing line winding body of the spool, the hollow portion formed in the fishing line winding body of the spool further reduces the weight of the spool and improves the braking efficiency. The casting function can be further improved, and the length of the cylindrical conductive ring in the spool axial direction can be shortened, and the backlash prevention device can be downsized.
