Description

  The present invention relates to a fishing reel spool provided so as to be movable back and forth (reciprocating in the axial direction) with respect to a reel body.

In a conventional fishing reel, a semi-annular bail is attached to the tips of a pair of support arms provided on a rotor via a bail support member so as to be normally reversible. When this bale is thrown toward the fishing line discharge position and the device is thrown, the fishing line wound on the spool is released, while the bale is reversed to the fishing line winding position and the rotor is rotated in the direction of winding the fishing line by operating the handle. Then, the fishing line is wound around the spool that reciprocates in conjunction with the rotation of the rotor.
The spool of the fishing reel is provided so as to be movable back and forth with respect to the reel body, and a spool body around which the fishing line is wound, a flange portion disposed at the front end of the spool body, and having a diameter larger than that of the spool body, and the spool body And a skirt portion disposed at the rear of the portion, and these are integrally formed of a metal material such as aluminum or a synthetic resin material such as polyethylene.
In this type of spool, the bobbin trunk is mounted on a spool shaft that is supported by the reel body so as to be movable back and forth, and the cross section perpendicular to the axis of the spool shaft of the bobbin trunk and the flange is formed in a circle, A cross-sectional shape including a spool shaft core of the bobbin trunk is known to be formed with a forward taper that is reduced in diameter toward the front, and that formed with a reverse taper that is reduced toward the rear.
For example, in Patent Document 1, the front hook portion of the spool is tapered in the direction opposite to the fishing line winding trunk portion, and is formed for a plurality of taper portions having taper angles sequentially reduced from the front end side of the front hook portion. A spinning reel spool is described.

However, the conventional spool has the following problems.
(1) When the spool is made of metal, it is difficult to reduce its weight, and it is difficult to maintain due to lack of corrosion resistance to seawater. There was a problem that it was easy to become.
(2) In the case where the spool is made of synthetic resin such as polyethylene, since these synthetic resins lack durability and wear resistance, the bobbin trunk is likely to be worn by sliding of the fishing line. There was a problem that the circumference of the part was worn out, and the feeding of the fishing line became unstable during reel throwing, and a good fishing result could not be obtained.
(3) Also, once the spool is partially worn, the spool is integrally formed, so the whole must be replaced, and the cost associated with such a spool is consequently high. There was a problem.
(4) In the spool described in Patent Document 1, when the fishing rod is swung down and the fishing line is released to the distance, the spool body is formed by a plurality of tapered portions, so that the fishing lines are drawn together when the fishing line is fed out or wound. Further, the sliding resistance fluctuates for each tapered portion with the spool surface, causing yarn breakage, and there is a problem that a sufficient flight distance may not be obtained.

  The present invention has been made in order to solve the above-described conventional problems, and is easily reduced in weight, has little sliding resistance with the fishing line, and can be stably performed without causing breakage of the fishing line when being drawn out or pulled in. An object of the present invention is to provide a fishing reel spool which is excellent in throwing operability and is excellent in wear resistance, durability and economy.

(Embodiment 1)
FIG. 1 is a side view of a reel on which a spool of a fishing reel according to Embodiment 1 of the present invention is mounted.
In FIG. 1, 10 is a fishing reel, 11 is a substantially cylindrical spool, and is detachably mounted via a support portion (not shown) provided with an oscillating mechanism of the reel body 12 of the fishing reel 10. It is reciprocated at a predetermined pitch in the direction.
Reference numeral 13 denotes a rotor which is rotated forward and backward through a handle 14 attached to the reel body 12 to wind and rewind the fishing line around the spool 11.
Reference numeral 15 denotes a semi-annular bale, which is disposed on the rotor 13 and rotates.
Reference numeral 16 denotes a fishing rod locking member, which attaches the reel body 12 to the fishing rod.
2A is a perspective view of a fishing reel spool, and FIG. 2B is a side sectional view thereof.
As shown in FIG. 2, the spool 11 includes a bobbin trunk 11 a around which the fishing line is wound by the rotor 13.
This bobbin trunk portion 11a has a tapered portion 11b whose diameter is reduced by a predetermined angle toward the tip,
A tip end portion of the taper portion 11b is formed with a thread stop flange portion 11c for expanding the diameter in the radial direction and stopping the feeding of the fishing line,
On the other hand, on the proximal end side of the tapered portion 11b, there are two reinforcing rib portions 11d and 11e formed in a ring shape by radially expanding from the outer periphery of the tapered portion 11b.
Further, a spool lid portion 11g is provided so as to extend the tip of the thread stop flange portion 11c and reduce the diameter in the radial direction of the spool 11 to form a lid.
In the center of the spool lid portion 11g, a fitting hole 11f for mounting the spool 11 via a knob 17 is provided in a locking portion (not shown) having a screw in the support portion of the reel body 12, and if necessary, Thus, the spool 11 can be removed from the reel body 12 and replaced, or can be maintained.

Polyamide resin such as monomer cast nylon (MC nylon) is used as a material for forming the taper portion 11b, the thread stop flange portion 11c, the reinforcing rib portions 11d and 11e, and the spool lid portion 11g constituting the bobbin trunk portion 11a of the spool 11. Are preferable in terms of processability, strength, weight reduction, and the like. The spool 11 is integrally formed by using a polyamide resin or the like as a raw material and cutting and grinding with a lathe or the like, or molding with an injection molding machine, blow molding machine, casting machine or the like.
Monomer cast nylon has the features of excellent seawater resistance, abrasion resistance, and mechanical strength. By polymerizing and molding nylon monomer under atmospheric pressure, it is mechanical, thermal, and chemical than ordinary 6 nylon. It is an improvement in the physical properties.
Monomer cast nylon is particularly slippery when the fishing line is a knitting yarn of PE line (knitting yarn with few ultra-fine polyethylene fibers knitted with almost no elongation). The PE line knitting yarn is preferably used because it is not stretchable like a single yarn made of nylon. However, when a conventional metal spool or plastic spool is used, the spool is greatly worn because it is a knitting yarn. When PE line knitting yarn is used, it is preferable to use monomer cast nylon in order to reduce sliding resistance with the fishing line.
A predetermined amount of carbonaceous reinforcing material such as carbon fiber, carbon powder, graphite powder, or ceramic material can be blended with such monomer cast nylon. For example, the wear resistance of the spool 11 and the sliding resistance with the fishing line can be further improved by adding 0.1 to 10% by weight with respect to 100% by weight of nylon.
The material contained in the monomer cast nylon is not particularly limited. For example, ceramic materials include alumina, zirconia, graphite, silica, silicon carbide, zeolite, alkali glass, phosphate, phosphoric acid. Zirconium, calcium phosphate, calcium carbonate, silica alumina magnesium and the like can be mentioned.
In addition to improving the wear resistance and the like, the rotational moment and weight required for the spool 11 can be adjusted by the blending amount of these containing materials.

  There is no particular limitation on the production method of the monomer cast nylon molded article, and as the lactam monomer polymerized in the casting mold, a substantially anhydrous ω-lactam having a 5-membered ring or more, for example, 2-pyrrolidone, ε-caprolactam, Examples include ω-caprolactam and ω-laurolactam. In the casting polymerization, a catalyst or cocatalyst usually used for anionic polymerization is usually used. For example, as the catalyst, alkali metal, alkaline earth metal and hydrides of these metals, hydroxides, oxides, carbonates, alkoxy compounds, Grignard compounds, etc., and as the catalyst, isocyanate compounds, urea Derivatives, acyllactams and the like. Furthermore, if necessary, addition of lubricants, antistatic agents, antioxidants, fillers, antiblocking agents, stabilizers, dyes, pigments, flame retardants, conductive agents, weathering improvers, reinforcing agents, nucleating agents, etc. You may make it add an agent in the said monomer.

The spool 11 can be formed by turning one by one using a round rod made of polyamide resin such as monomer cast nylon. Such a polyamide resin does not corrode against seawater unlike a metal resin, and is formed by twisting a plurality of yarns and forming a PE line having almost no elasticity while winding it around the spool 11. If soaked in lukewarm water, the salt that is a major enemy of the PE line can be easily removed.
Furthermore, since the spool 11 made of monomer cast nylon is excellent in compatibility with the PE line, it can be suitably used with little yarn loosening due to heat and temperature difference.
The spool 11 is attached to the reel body 12 through an oscillating mechanism so that the spool 11 can reciprocate, and the distance between the top dead center and the tip of the bail 15 is set in a range of 3 to 10 mm. Yes. As a result, the space around the spool 11 surrounded by the rotor 13 and the bail 15 is set to a minimum, the surface area of the thread winding surface is increased, and the fishing line feeding and winding operability is improved. Yes.
That is, by increasing the spool diameter and the surface area, the number of yarn windings can be reduced, the yarn discharge resistance can be reduced, and the yarn winding speed can be improved.

The taper portion 11b is inclined from the front end side with a predetermined spool surface taper angle θA with respect to the spool shaft. As shown in FIG. 3, generally, when the taper surface taper angle θA is small, the yarn separation from the taper portion 11b becomes unstable or the yarn collapses (the release resistance is reduced). To become big).
On the other hand, if the taper surface taper angle θA is large, a trouble called backlash that tends to come out in a state where the line is entangled when the fishing line is released tends to occur (the backlash occurrence rate increases), which is not preferable. In the present invention, the taper surface taper angle θA is preferably set in the range of 0.01 degrees to 4 degrees, and more preferably in the range of 1 degree to 2 degrees.
The thread retaining flange portion 11c is formed to have a taper gradually increased in diameter from the front end outer diameter of the taper portion 11b, and is a portion for locking the fishing line at the front end thereof. An inclined surface having a slight curvature inclined at an angle of 15 to 45 degrees is formed. When the front edge taper angle θB is smaller than 15 degrees, there is a tendency that it is difficult to securely lock the fishing line (the occurrence rate of backlash increases). Conversely, the front edge taper angle θB is 45 degrees. Exceeding the range is not preferable because the separation of the fishing line wound around the tapered portion 11b becomes worse (the release resistance increases).
If necessary, a spiral groove for guiding the winding or unwinding of the fishing line can be formed on the outer peripheral surface thereof, or a large number of ring-shaped grooves can be formed, whereby the fishing line can be wound around the tapered portion 11b. Unwinding can be performed smoothly. Details will be described later.

  The inclined surface 11c1 of the thread stop flange portion 11c is an inclined surface where the fishing line comes into contact when the line (fishing line) is released and the frictional force is particularly increased. The inclined surface 11c1 is subjected to a mirror finishing process such as buffing. It is desirable to keep it. Accordingly, it is possible to reduce the frictional resistance between the line and the inclined surface 11c1, reduce the discharge resistance of the line, and perform comfortable throwing.

  The two reinforcing rib portions 11d and 11e are provided at the rear end of the tapered portion 11b, and have a function of enhancing the overall rigidity of the spool 11 and securely holding the wound fishing line on the tapered portion 11b. . The reinforcing rib portions 11d and 11e are formed integrally with the tapered portion 11b.

  Since the spool 11 of the fishing reel of the first embodiment is configured as described above, it is possible to reduce the weight and improve the maintainability while maintaining good operability such as fishing line sliding resistance of the reel itself. be able to. In addition, the improved slipping performance of the spool enables stable feeding and winding operations of the fishing line, and the spool is made of polyamide resin such as MC nylon. It is possible to provide a fishing reel spool which is excellent in adaptability when using a line and is excellent in wear resistance, durability and economy.

In the spool 20 of the fishing reel of the second embodiment, the taper portion 21b and the thread stop flange portion 21c constituting the bobbin trunk portion 21a are configured separately from polyamide resin such as MC nylon, respectively. Yes. The thread stop flange portion 21c and the taper portion 21b are screwed through the respective screw portions 21h and 21j, and can be disassembled and assembled as necessary.
As a result, the combination of different materials and the inclination angle θA, θB of the thread take-out depending on the usage situation of the fishing reel 10 and the operability such as wear characteristics and sliding characteristics required for the bobbin trunk 21a. By appropriately selecting different combinations and assembling the spool 20, it is possible to easily adjust the threading operability and the like.
Further, since the tapered portion 21b is provided with a spiral portion 21g formed at a pitch of about 0.2 to 0.5 mm for facilitating the winding of the fishing line, the fishing line can be fed out from the spool 20 or the spool. The winding operation to 20 can be performed stably, and the fishing line is firmly fixed so that the fishing line does not slip at the beginning of winding of the important fishing line. Can be prevented.
Further, by providing the spiral portion 21g on the bobbin winding surface as described above, the surface of the yarn wound around the bobbin winding surface does not rise like a projection, and a flat bobbin winding surface can be formed and maintained. It is possible to prevent the fishing line from being caught on the protruding portion.
