Description

[Detailed description of the invention] FIELD OF THE INVENTION The present invention relates to fishing reels.

Recently, fishing reels have been manufactured by molding some of the reel's constituent members from reinforced synthetic resin containing high-strength fibers such as carbon, velvet, and glass fibers. , , those with increased hardness and strength have been proposed.

However, since the mixing ratio of synthetic resin with high heat shrinkability in the whole must exceed a certain value, when cooling after molding, one synthetic resin part shrinks more in the thicker part, causing so-called shrinkage. In addition to the problem of poor dimensional stability, the overall hardness and strength values were also affected by changing the combination of each material of synthetic resin and high-strength fiber, or by changing the mixing ratio. , thicker than a certain limit (there was a problem that it could not be done).

As a result of research to solve one or more problems, the present invention focuses on fine single crystal fibers such as potassium titanate and silicon carbide.
Taking advantage of the fact that the fiber has a high strength compared to synthetic resin, is stable without thermal shrinkage, and has the property of clinging to the synthetic resin around the molding area, By reducing the mixing ratio and mixing the fine single crystal fibers accordingly, each single crystal fiber is formed by molding, in which the synthetic resin reinforced by containing the high strength fibers is arranged in a single dispersion. The above-mentioned problem was solved by attaching them to each other and forming a strong structure in which four parts were connected and reinforced each other.

The object of the invention is that compared to molded products made of reinforced synthetic resin containing high-strength fibers, the molded product contains less synthetic resin (and contains fine single-crystal fibers), making it easier to cool down after molding. To provide a lightweight fishing rod that can minimize the sink marks that sometimes occur especially in thick parts, thereby improving one-dimensional stability and increasing overall hardness and strength. It is in.

The structure of the fishing reel of the present invention is such that some or all of the components constituting the fishing reel are made of synthetic resin, microscopic monocrystalline fibers such as potassium titanate and silicon carbide, and high-quality materials such as carbon fiber and glass fiber. It is characterized by being molded from a reinforced synthetic resin containing strength fibers.

An embodiment of the fishing reel of the present invention will be described below with reference to the drawings.

What is shown in the drawing is a spinning reel tearer. In one drawing, (1) is a reel body with mounting legs (11), (2) is a handle member, and (3) is a handle member (2).
(4) is a spool shaft supported by the master gear (6) so as to be freely movable back and forth in conjunction with the bite gear (3); (7) is a reel body (1); The rotating frame (8) is a spool supported on the spool shaft (6) projecting forward of the rotating frame (7). In this case, a part or all of all the constituent members, including each of the above-mentioned members (1) to (8) constituting the fishing rod, as well as other members not marked, are made of synthetic wood.
In addition, fine single crystal fibers such as potassium titanate and silicon carbide, as shown in the Kerr drawing, are the main components (1) to (8) that make up the fishing linyl. The components that are large and cause a large increase in overall overlap, namely the reel body (1), the one-rotation frame (7), and the spool (8), are molded from the reinforced synthetic resin,
In addition to the size of the volume, parts that can be manufactured by molding synthetic resin can reduce manufacturing costs.
For example, the master gear (3) and pinion gear (4)
may be molded using the reinforced synthetic resin, and the reinforced synthetic resin may be used for other members as needed.

Furthermore, the synthetic resin constituting the reinforced synthetic resin includes:
Both thermoplastic resins with good moldability and workability and thermosetting resins with high strength and impact resistance can be used. Nylon resin has a large slip resistance and low driving noise, and polyacetal resin has excellent mechanical strength, oil resistance, abrasion resistance, and repeated load resistance, and has strong mechanical strength. Polycarbonate that also generates less noise when driving $
4-to resin, other polyphenylene sulfide resins,
Polybutylene lentil reflex' tallate resin, ABS+f! In addition, as the thermosetting resin, epoxy resin, phenol resin, unsaturated polyester resin, etc. are used.

Further, the high-strength fibers such as carbon fibers and glass fibers added to the synthetic resin may be used alone or in combination, and have an average fiber length of 3 or more, for example, in the spool (8). The reel body (1) uses a 12 egg reel, and a 25 tm reel is used for the reel body (1).

Further, the single crystal in the single crystal fiber added to the synthetic resin is, for example, a so-called whisker crystal, and the whisker crystal is
It is grown as needle-shaped crystals during hydrogen reduction of metal oxides, geothermal decomposition thereof, condensation of steam, etc. Potassium titanate (K, 06TIO,), silicon carbide, etc. are used. The thickness of this whisker crystal is 0.1 to 1oPm, the length is, for example, 4QPm, and the number of dislocations it contains is extremely small (therefore, the number of dislocations contained is extremely small (therefore, the number of dislocations contained within the crystal is small, causing slippage and plastic deformation). The external force required to generate the crystal, that is, the strength of the crystal, has a large value close to the ideal value (1/100 or more of the rigidity) of the crystal in a state without dislocation, and moreover, the synthetic resin In addition, even if the material is heated to the molding temperature and then cooled, the amount of thermal shrinkage is extremely small.

- By mixing the single knots &am with the high strength m fibers in the synthetic resin and molding them, they are evenly dispersed and arranged in the molded product, and each of the 11ζ and high strength *a The reinforced synthetic resin is tied together to form a complex network-like strength structure that organically connects and reinforces each other.

By the way, in the reinforced synthetic resin having a composition T of the synthetic resin and single crystal fibers, nylon 66 is used as the synthetic resin, and potassium titanate (x
, orso,), and the weight percent of these nylon 66 and the weight percent of potassium titanate were 100, 90, and 8, respectively.
Table 1 shows a comparison with various characteristic values when f = 0.70.60 (!: 0-10-20-50, 4CJ and 4CK).

Continued below on the next page (Nie, 14 ・1.) According to the above data, the weight ratio of the potassium titanate is 1.
For example, 20% is considered preferable. The reason for this is to maintain good moldability by maintaining the synthetic resin ratio of 70%, and as is clear from Table 1, the Rockwell hardness value is lower than the weight ratio of 0. % to 10% to 20
%, from 108 to 111 to 1
16G increases significantly, but the weight ratio is increased from 20% to 6
Even if it is increased to 0%, it remains the same value of 116 without any increase.In other words, when the true a ratio is 20%, the Rockwell hardness value reaches almost a saturated state, so the weight ratio is.

This is because 20% is sufficient in terms of Rockwell hardness. Second, the IZOD impact value is 7 when the weight ratio is increased from 0% to 10 to 60%.
．． Increased from 6 and reached a constant value of 8.5, making the 1 weight ratio 40%
1 weight ratio is significantly reduced to 5.5 by increasing the IZOD impact value by 20% of the first value.
10 to 60% containing □ is preferable, and thirdly,
What is the specific gravity value?

It increases as the weight ratio increases, but when the weight and ratio are 2
This is because if the weight ratio is about 0%, the specific gravity value can be suppressed to a small value of 1.67, which is about a 20% increase compared to when the weight ratio is 0%. Sara.

Fourthly, by setting the weight ratio to 20%, the tensile strength value can be significantly increased by about 20% compared to the weight ratio of 0%. .

(The weight ratio of the potassium titanate is, for example, 20
%, but judging from the data in Table 1 above, this M1 ratio is within the selected range of 20 to 60%.
It can be seen that excellent characteristics can be obtained.

Therefore, as mentioned above, the weight ratio of potassium titanate is 20~
If it is 30%, the remaining 8υ~70% is composed of the above-mentioned nylon 66 and high strength TSM, and nylon 66
% by weight that can maintain good moldability, for example, 3
By ensuring 0%, the above-mentioned good properties can be obtained while maintaining good moldability as a whole.

That is, in the present invention, the component of the fishing reel made of the HIJ reinforced synthetic resin containing the n'J strength fiber and the single crystal fiber in the synthetic resin has a small ratio and can be made lightweight. Moreover, by using a thermoplastic resin such as nylon resin as the synthetic resin, it has good moldability and can be easily molded, and it does not cause sink marks even in thick areas when cooling after molding. minimize rlt
lj, and the dimensional stability can be the same as above. In addition, the single crystals are evenly dispersed in the reel's constituent members, and the synthetic resin containing the above-mentioned surface strength fibers is wrapped around each crystal, forming a strong structure that organically connects and reinforces each other throughout. In order to achieve this, the 120D impact value and tensile strength values are significantly higher than the conventional one, which is simply a synthetic resin mixed with high-strength fibers. Moreover, even if the load is suddenly applied, it can be reliably counteracted.

In addition, in the explanation above, nylon 66, carbon fiber and glass fiber, and potassium titanate are selected as specific examples of the synthetic resin, high-strength fiber, and single crystal fiber that compose the reinforced synthetic tree JJH, and each composition is -60% weight ratio, respectively
, 60%, 20%, and 20%, but it goes without saying that the selection of one composition and the weight ratio of each composition can be changed at any time.According to the present invention, good molding can be achieved. It maintains its properties and does not cause sink marks even in thick areas.
It has good dimensional stability, can be easily mass-produced, can be made large, and can reliably withstand large loads that are suddenly applied during fishing.
