Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fishing reel characterized by a drag mechanism.

[0002]

2. Description of the Related Art Conventionally, in a fishing reel, when a spool is wound around a fishing line, the fishing line is allowed to rotate with a constant braking force (drag force) when the fish is caught on the spool. It has a built-in drag mechanism. This drag mechanism is provided with a lining material and a mating material that is in contact with the lining material so as to apply a predetermined braking force to the spool by the frictional force generated by being pressed by the pressing member.

Generally, the lining material is widely known to be made of wool felt, resin such as polyester, and the like, and this is used in combination with a metallic counterpart material such as SUS. The following problems occur in a fishing reel incorporating a drag mechanism including such a lining material and a mating material.

There is a large difference in the mechanical properties between the lining material and the mating material in the above-mentioned drag mechanism, and particularly the mechanical properties (heat resistance, strength, hardness, etc.) of the lining material are greatly inferior to the mating material. Therefore, the lining material is significantly worn during the drag operation, which requires frequent replacement. In addition, when the fishing line is fed out at a high speed and a large frictional force acts, such as when a large fish is caught, the lining material is carbonized, and the drag resistance is significantly reduced (weak to heat).

Therefore, in order to improve these problems, in Japanese Utility Model Publication No. 4-27338, a woven cloth formed of heat resistant fibers is bonded to at least one side surface of a substrate having heat resistance and flexibility. A fishing reel incorporating a drag mechanism with a lining material is disclosed.

[0006]

However, since the lining material having the above-mentioned structure requires the substrate, the unit price of the parts becomes high and the cost of the reel unit becomes high. Further, according to the lining material having the above-mentioned configuration, although abrasion and reduction in drag proof strength can be prevented, in a woven fabric formed of heat resistant fibers, the frictional force per unit area becomes small, which is necessary and sufficient. In order to obtain the frictional force, the frictional area must be increased, which inevitably increases the size of the drag mechanism and the reel body.
In particular, if a low-friction material is used to minimize stick-slip, the frictional force per unit area becomes even smaller. Therefore, in order to obtain the necessary and sufficient frictional force, the drag mechanism becomes larger and the reel unit also It becomes large.

The present invention has been made on the basis of the above-mentioned problems, and is intended to improve the heat resistance and durability of the drag mechanism, reduce the cost, and reduce the size of the reel unit. An object of the present invention is to provide a fishing reel incorporating the.

[0008]

In order to achieve the above object, the fishing reel according to the present invention has a spool supported on the reel body by rotation of a handle rotatably supported on the reel body. A lining material in the above-mentioned drag mechanism, and a lining material in the above drag mechanism, in which a fishing line is held and wound, and a drag mechanism including a lining material for braking the rotation of the spool in the fishing line winding direction in the fishing line winding state is incorporated. It is characterized in that (1) all are made of metal, (2) at least one is made of ceramics, and (3) both are made of ceramics.

Since there is no large difference in mechanical properties between the metals, between the ceramics, and between the metal and the ceramics, even if a large frictional force is applied by making surface contact with each other, the wear is effective. To be prevented. Therefore, when the above-described configuration is applied to the lining material and the mating material in the drag mechanism of the fishing reel, even if a large frictional force acts due to the surface contact with each other, the wear can be effectively prevented. Since carbonization and melting are prevented even when frictional heat is generated, durability and heat resistance are improved. Further, in the above combination, since the frictional force per unit area is large, even if the drag mechanism is made compact, it is possible to obtain a sufficient predetermined frictional force (drag force), and the reel itself can be made compact. Becomes

1 is a view showing the internal structure of an embodiment (double-bearing type reel) of a fishing reel according to the present invention. First, the overall configuration of the dual bearing reel according to the present embodiment will be described.

The dual-bearing reel 1 includes a left and right frame 2a,
It has a reel unit 4 having left and right side plates 3a and 3b mounted on the left and right frames 2a and 2b, respectively.
A spool shaft 6 to which a spool 6a around which fishing line is wound is attached is rotatably supported between (the left and right side plates 3a, 3b) via a bearing.

The spool 6a has a handle 1 attached to an end of a handle shaft 10 protruding from the right side plate 3b.
By rotating 0a, it is rotationally driven via the driving force transmission mechanism. In this case, the handle shaft 10 is rotatably supported via a bearing between the right frame 2b and the right side plate 3b, and is configured to be rotatable only in the fishing line winding direction by the one-way clutch 12. .

The drive force transmission mechanism is rotatably attached to the handle shaft 10, has a drive gear 15 having an annular recess, meshes with the drive gear 15, and has a bearing on the right frame 2b and the right side. The pinion 17 is rotatably supported between the plate 3b and the plate 3b.

A circumferential groove 17a is formed on the outer circumference of the pinion 17, and a clutch plate 18 axially movable by a clutch operating member (not shown) is engaged with the circumferential groove 17a. There is. In this case, by operating the clutch operating member to move the pinion 17 in the axial direction, a driving force transmission state (clutch ON state) as shown in FIG. 1 or a spool free rotation in which the pinion 17 is disengaged from the spool shaft 6 is generated. State (Clutch OFF state)
Can be switched to. The return from the clutch-off state to the clutch-on state is performed by a well-known return mechanism in addition to the operation of the clutch operating member.
It can also be performed by the winding operation of a.

A known level winder 20 is provided between the left and right frames 2a and 2b, and the fishing line guide member 2 is operated by rotating the handle 10a.
0a is reciprocated right and left along the worm 20b so that the spool 6a is evenly wound with the fishing line through the fishing line guide portion.

On the left frame side of the spool shaft 6, an annular conductor 22 that rotates integrally with the spool shaft 6 is formed.
And a magnet 23 provided in the left frame 2a and provided with an annular recess into which the annular conductor 22 is inserted.
Is moved along with the high speed rotation of the spool, the magnetic force acts on the annular recess to prevent the spool 6a from over-rotating and to prevent the yarn entanglement.

The drive gear 15 is engaged with a drag mechanism 30 which applies a drag force to the spool 6a when the fishing line is fed from the spool 6a during fishing. The drag mechanism 30 in the present embodiment includes a lining material 31 housed in the annular recess of the drive gear 15, two mating materials 32 and 33 that are in contact with and sandwich the lining material 31, and a mating material. And a pressing member 35 that presses the material 33. In this case, the lining material 31
Is a state in which it can freely rotate, the mating member 32 is in a state in which it can rotate integrally with the drive gear 15 with respect to the handle shaft 10, and the mating member 33 can freely rotate in integral with the handle shaft 10 with respect to the drive gear 15 (The detailed configurations of the lining material 31 and the mating materials 32 and 33 will be described later).

The pressing member 35 is moved to the driving gear side by rotating the drag operating member 36 attached to the handle shaft 10, thereby pressing the mating member 33 and the lining member 31 and driving them. The mating material 32 that rotates integrally with the gear 15 is pressed to drive the gear 1
A predetermined pressing force is applied to 5. A rotating body (ratchet) in which this pressing force rotates integrally with the handle shaft 10.
By acting on 37, a predetermined drag force (braking force) is generated between the handle shaft 10 and the drive gear 15.

Therefore, if the tightening force of the drag operating member 36 is loosened, when the spool 6a rotates in the fishing line payout direction such as when a fish is caught, the drive gear 15 causes the lining material 31 to move against the handle shaft 10. Since the spool 6a can be rotated while being applied with a braking force, the spool 6a can be rotated even when a sudden load acts on the fishing line, and thus the spool 6a is prevented from breaking.

Next, the structures of the lining material 31 and the mating materials 32 and 33 in the drag mechanism 30 will be described. As shown in FIG. 2, the lining material 31 is rotatably disposed in the recess 15 a of the drive gear 15 while being sandwiched between the mating materials 32 and 33. The mating member 32 is disposed so as to rotate integrally with the drive gear 15 by the tongue piece 32a engaging with the groove 15b formed in the inner peripheral wall defining the recess 15a, and the mating member 33 has a non-circular cross section. It is arranged so as to be prevented from rotating with respect to the handle shaft by the insertion hole 33a. And, as mentioned above, FIG.
The drag operating member 36 shown in FIG.
By moving 5 in the axial direction, the frictional force generated between the lining material 31 and the opposing materials 32 and 33 causes
The drive gear 15 is adapted to generate a desired braking force (drag force).

In the above structure, the lining material 3
1, and the mating members 32 and 33 are formed of the following materials. In the combination described in detail below, it is preferable that both mating materials 32 and 33 satisfy the conditions for one lining material, but even if one of the mating materials satisfies the condition. good.

(1) Both the lining material and the mating material are made of metal. In this case, as the metal material, for example, an iron-based material, a copper-based material, an aluminum-based material, a titanium-based material, a nickel-based material, a zinc-based material, a chromium-based material, or the like can be used. As described above, by using the metal material for both the lining material and the mating material, there is no great difference in the wear characteristics between the both, and the durability can be improved. In addition, such a combination of materials has a large frictional force per unit area, so that the required frictional force can be obtained without increasing the lining material and the mating material, which makes the drag mechanism compact. Therefore, the entire reel can be made compact. Further, since each is formed of a single material (not a composite structure), cost can be reduced.

(2) Both the lining material and the mating material are made of ceramics. In this case, as the ceramic material, for example, alumina, zirconia, silicon nitride,
It is possible to use silicon carbide or the like. In this way, by using the ceramic material for both the lining material and the mating material, as in the above, there is no great difference in the wear characteristics between them, and the durability can be improved. In addition, such a combination of materials has a large frictional force per unit area, so that the required frictional force can be obtained without increasing the lining material and the mating material, which makes the drag mechanism compact. Therefore, the entire reel can be made compact. Further, since each is formed of a single material (not a composite structure), cost can be reduced.

(3) One of the lining material and the mating material is made of metal and the other is made of ceramics. In this case, the above-mentioned materials can be used as the metal material and the ceramic material. Even with such a combination of materials, the durability can be improved as described above, the drag mechanism can be made compact, and the entire reel can be made compact, and further the cost can be reduced.

Since the lining material in the combination of (1) to (3) described above has higher heat resistance than conventional lining materials such as felt and polyester, when the drag mechanism is operating. Even when the frictional heat is generated, the washer shape can be maintained, the base material is not carbonized or melted, and the durability and heat resistance of the drag mechanism itself can be improved.

In the combination of (1) to (3) described above, it is preferable to further configure as follows. (A) A lubricant (oil, grease, etc.) is applied to the surface of the lining material and the mating material. As described above, by using the lubricant, the drag mechanism can be operated smoothly and good friction characteristics can be maintained.

(B) Either or both of the lining material and the mating material are made porous. In this way, by having a porous structure, the retaining force of the lubricant is increased and the lubricant can be retained in the holes, so that an oil film is always formed on the friction surface, and the durability can be further improved and the stick The slip can be reduced, the drag mechanism can be operated smoothly, and more favorable friction characteristics can be maintained.

In the case of a porous metal material, it is preferable that the porosity is formed in the range of 20 to 80%, but if the porosity is too high, durability is unfavorable.
It is preferable to set it in the range of 50%. Further, it is preferable that the pore diameter is formed in the range of 1 to 100 μm, but in the case of applying the lubricant, considering the retaining property of the lubricant, etc.
It is preferably set in the range of 0 to 50 μm.

In the case of a porous ceramic material,
The porosity is preferably formed in the range of 20 to 80%, but if the porosity is too high, durability is not preferable, so it is preferably set in the range of 20 to 50%. Further, the pore diameter can be formed in the range of 1 to 100 μm, but in the case of applying the lubricant, it is preferably set in the range of 10 to 50 μm in consideration of the retaining property of the lubricant and the like.

In practice, the present invention relates to a fishing reel incorporating a drag mechanism having the above-described lining material and a mating material, and a conventional fishing reel incorporating a drag mechanism having a lining material and a mating material. When the drag resistance test was conducted, the results shown in the graphs of FIGS. 3 (a) and 3 (b) were obtained. This test was performed under the same conditions (the lining material and the mating material were dry, the pressing pressure was 3.0 Kgf / cm ² , and the rotation speed was 5 rpm) using a known drag tester. The change in torque with time was measured by changing the materials of the lining material and the mating material.

FIG. 3 (a) shows a structure in which the lining material is made of ceramics and the mating material is made of metal in the above-described structure (porous ceramics-porous metal, porous ceramics-metal, ceramics-metal). Is the measurement result of the test. The lining material is stainless steel,
The conventional one () in which the mating material is felt is also shown.

As is clear from this test, in any combination, higher yield strength than the conventional combination was obtained,
Above all, it was obtained that the lining material and the mating material are most preferably a combination of porous ceramics and porous metal. In addition, as shown in the figure, in the conventional combination, after the tension was applied, there was a characteristic that the torque jumped up and dropped until it became a stable state. It was possible to obtain a characteristic that it smoothly transitions and stabilizes without changing to. According to such characteristics, it is possible to obtain the effect that the fishing line is hard to be broken in the initial stage when the drag acts, such as when the fish is caught.

Further, FIG. 3 (b) shows that among the above-mentioned constitutions,
It is the measurement result which tested the thing which made both the lining material and the other material metal (porous metal, metal which is not porous).

As is apparent from this test, both combinations have higher yield strength than the conventional combinations,
It was found that it is preferable that the lining material and the mating material are both porous metals.

Also in this structure, after the tension is applied, until the stable state is achieved, there is obtained the characteristic that the torque smoothly changes and stabilizes without abrupt change of the torque. The effect that the fishing line is hard to break is obtained in the initial stage when the drag acts, such as when a fish is caught.

Although the fishing reel of the present invention has been described above, the present invention can be applied to a spinning reel as well as the dual-bearing reel used in the above-described embodiment.

[0037]

As described above, according to the structure of the present invention, the heat resistance and durability of the drag mechanism can be improved and the cost can be reduced because the lining material is composed of a single member. In addition, the reel body can be downsized.
