Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drag mechanism, and more particularly to a front drag mechanism for a spinning reel mounted between a spool of a spinning reel and a spool shaft.

[0002]

2. Description of the Related Art In general, a spinning reel has a reel body mounted on a fishing rod and having a handle, a spool provided on the reel body, and a rotor for winding a fishing line around the spool. The spool is
It has a bobbin trunk on which a fishing line is wound around the outer peripheral surface, a skirt portion integrally formed at the rear of the bobbin trunk, and a flange member mounted on the front of the bobbin trunk.

[0003] A front drag mechanism for braking the rotation of the spool in the line feeding direction is mounted inside the bobbin trunk. By installing this front drag mechanism, it becomes difficult for the fishing line to break even when the load suddenly rises when fish is applied to the device. The front drag mechanism includes an operation knob, a spring member, a pressing member, and one or more drag disks. The operation knob is for adjusting the drag force, and is rotatable with respect to the spool. The operation knob has a nut member screwed to the spool shaft, and a knob member to which the nut member is mounted so as to be non-rotatable and movable in the axial direction. The spring member is a coil spring whose tip contacts the nut member and is mounted on the outer peripheral side of the spool shaft. The pressing member is mounted on the operation knob so as to be rotatable and non-movable in the axial direction, is non-rotatable with respect to the spool shaft, contacts the rear end of the spring member,
This is a member whose pressing force changes due to a change in the spring force of the spring member. The drag disk is arranged in contact with the bobbin trunk, and changes the frictional force with the bobbin trunk by a change in the pressing force of the pressing member.

In this kind of drag mechanism, by adjusting the amount of compression of the spring member by turning the operation knob, the force with which the drag disk presses the spool changes, and the drag force is adjusted according to the spring force of the spring member. it can. In general, in order to reduce the cost of the reel, it is preferable that spools having different model numbers can use the same front drag mechanism. If the model number of the spool is different, the thickness of the fishing line to be wound is different, and the strength of the fishing line is also different. Usually, in the drag mechanism, it is desirable that the drag force becomes the maximum at about 1/2 of the strength of the fishing line, and the drag force can be set finely at about 1/3 of the strength. For example, when winding a fishing line having a strength of 24N (Newton), the maximum drag force is 12N.
It is sufficient if the drag force can be finely adjusted at about 8N.

[0005]

In the above-mentioned conventional configuration,
The drag force changes according to the spring force of the spring member until the spring member comes into close contact. Therefore, until the spring member comes into close contact, the drag force changes gently with respect to the amount of rotation of the operation unit, and the drag force can be set finely. But,
When the spring member comes into close contact, the operation knob directly presses the pressing member, and the drag force increases rapidly with respect to the amount of rotation of the operation knob. Therefore, in the conventional front drag mechanism, when the spring force is set so that the drag force can be finely adjusted with respect to a certain spool, the spring member comes into close contact with the spool around which a fishing line having higher strength is wound. As a result, there arises a problem that the drag force cannot be set finely. This problem also occurs when one line is wound with fishing lines having different strengths.

An object of the present invention is to make it possible to set an appropriate drag force for fishing lines having different strengths in a front drag mechanism.

[0007]

A front drag mechanism for a spinning reel according to a first aspect of the present invention is a mechanism mounted between a spool of the spinning reel and a spool shaft.
An operation unit, an elastic unit, a pressing member, and one or more drag disks are provided. The operation unit is a knob rotatable with respect to the spool, having a nut member screwed to the spool shaft, and a knob member to which the nut member is non-rotatably and axially movable. The elastic means is a means mounted on the outer peripheral side of the spool shaft, the tip of which is in contact with the nut member and can be compressed, and the spring constant increases in the middle. The pressing member is rotatably mounted on the operation unit so as not to be movable in the axial direction, is not rotatable with respect to the spool shaft, and comes into contact with the rear end of the elastic means to change the pressing force due to a change in the spring force of the elastic means. It is a member. One or more drag disks are arranged in contact with the spool, and the frictional force with the spool changes according to the change in the pressing force of the pressing member.

In this drag mechanism, when the knob member of the operating section is turned to bring the pressing member into contact with the drag disk and then the knob member is further turned, the elastic means is gradually compressed,
Initially, the spring force gradually increases at the first spring constant, and the drag force increases accordingly. When the pressure changes to the second spring constant during compression, the spring force gradually increases at a rate larger than the first spring constant, and the drag force increases accordingly. When the compression of the elastic means ends, the drag force increases sharply. Here, since the spring constant increases on the way, the drag force can be finely adjusted over a wide range by appropriately setting the spring constant of the elastic means. Therefore, an appropriate drag force can be set for fishing lines having different strengths. Therefore, the drag mechanism having the same structure can be adopted for two types of spools having different strengths, and the drag force can be finely set in a wide range for one spool.

A front drag mechanism for a spinning reel according to a second aspect of the present invention is the front drag mechanism according to the first aspect, wherein the elastic means includes a first spring member whose tip contacts a nut member, and a first spring member.
A second spring member, which is mounted in series on the rear end side of the spring member and which has a different spring constant from the first spring member. In this case, the spring constant can be easily changed during compression by two spring members having different spring constants arranged in series.

[0010] A front drag mechanism for a spinning reel according to a third aspect of the present invention is the mechanism according to the second aspect, wherein the spring constant of the first spring member is smaller than the spring constant of the second spring member.
In this case, when the operating portion is turned in a state where the pressing member is in contact with the drag disk, first, a combined spring constant of a reciprocal of a value obtained by adding the reciprocals of the respective spring constants of the first spring member and the second spring member. As a result, both spring members are compressed, and the drag force increases in proportion to the combined spring constant. Then, when the first spring member having a small spring constant comes into close contact, the drag force increases in proportion to the spring constant of the second spring member. Here, the drag force can be finely adjusted over a wide range by setting the spring constants of the two spring members in accordance with the strength of the fishing line.

[0011] A front drag mechanism for a spinning reel according to a fourth aspect is the mechanism according to the second or third aspect, further comprising a ring member mounted between the first spring member and the second spring member. In this case, even if the diameters of the springs are different, the force can be reliably transmitted by the ring member. A front drag mechanism for a spinning reel according to a fifth aspect of the invention is the mechanism according to the first aspect, wherein the elastic means includes a first spring member having a front end in contact with the nut member and a rear end in contact with the pressing member; And a second spring member which is mounted in parallel on one of the inner and outer circumferences of the spool shaft and has a free length shorter than the first spring member. In this case, when the operation unit is turned while the pressing member is in contact with the drag disk,
Initially, the first spring member compresses and the drag force increases in proportion to its spring constant. When the compression of the second spring member also starts, the drag force increases in proportion to the spring constant obtained by adding the spring constants of both spring members. Here, the drag force can be finely adjusted over a wide range by setting the spring constants of the two spring members in accordance with the strength of the fishing line.

A front drag mechanism for a spinning reel according to a sixth aspect of the invention is the mechanism according to any of the second to fifth aspects, wherein at least one of the two spring members is a coil spring. In this case, by using a coil spring, the combination of two spring members in series and in parallel can be easily realized, and the setting of the spring constant and the setting of the moving amount of the nut member are also easy.

A seventh aspect of the present invention provides a front drag mechanism for a spinning reel according to any one of the second to fifth aspects, wherein at least one of the two spring members is a disc spring. In this case, by using a disc spring, a series and parallel combination of two spring members can be easily realized with a short axial length. Invention 8 is a spinning reel front drag mechanism according to any one of Inventions 1 to 7, wherein at least one of the plurality of drag discs is not rotatable with respect to a spool shaft and rotatable with respect to the spool. The rest cannot rotate with respect to the spool and can rotate with respect to the spool shaft. In this case, the drag force can be more finely adjusted by using two types of drag disks.

According to a ninth aspect of the present invention, there is provided a spinning reel front drag mechanism according to any one of the first to eighth aspects, wherein the spool has a disk-shaped wall portion rotatably mounted on the spool and an outer periphery of the wall portion. And a cylindrical portion provided on the side of the cylindrical portion, a fishing line is wound around the outer periphery of the cylindrical portion, and one or more drag disks are arranged between the pressing member and the wall portion in contact with both. ing.

3, water may penetrate, the fixing member 83 may get wet, and the drag force may fluctuate.

The fixing member 83 as a drag disk and the disk member 86 are arranged in contact with the wall surface 56 of the spool 4, and the frictional force (drag force) with the spool 4 due to a change in the pressing force of the pressing member 63. Changes. Between the knob member 65 and the pressing member 63, there is provided a second sound generating mechanism 70 that emits sound by the relative rotation of the two, that is, the operation of the operation knob 61. Second sounding mechanism 70
Is a sounding hole 75 formed in the cylindrical portion 63a of the pressing member 63, and a sounding pin 76 housed in the knob member 65.
And a sounding spring 77 formed of a coil spring for urging the sounding pin 76 toward the sounding hole 75. The rear end surface of the knob member 65 is formed at two positions opposite to the sound output hole 75.

[Reel Operation and Operation] Before fishing, the drag force is adjusted according to the size and type of fish. To adjust the drag force, the knob member 65 is turned. When the knob member 65 is turned clockwise, for example, the pressing member 63 presses the fixing member 83 via the coil springs 66 and 67 by the nut 64 screwed to the spool shaft 15. This increases the drag force. At this time, the sound output pin 76 repeatedly collides with the sound output hole 75 at predetermined intervals due to the relative rotation of the pressing member 63 and the knob member 65, and generates a light click sound with good crispness.

At the time of adjusting the drag force, the spring constant k is not changed until the coil spring 66 having a small spring constant comes into close contact.
k = k1 · k2 / (k1 + k2) (where k1: the spring constant of the coil spring 66, k2: the spring constant of the coil spring 67), and k2 when closely contacted. As a result, the relationship between the drag force acting on the drag disk and the amount of rotation of the operation knob 61 is determined by appropriately setting the two spring constants as shown in FIG. The inclination after the close contact becomes larger, and the further the coil spring 67 comes into close contact, the larger the inclination. Therefore, in the case of a fishing line with low strength, the drag force can be adjusted in a region where the spring constant is small, and in the case of a fishing line with high strength, the spring constant is adjusted so that the drag force can be adjusted in a region with a large spring constant. Set according to the intensity of By determining the specifications of the coil springs 66 and 67 with the set spring constant, the drag force can be finely adjusted in a wide range, and an appropriate drag force can be set for fishing lines having different strengths.

At the time of casting, the bail arm 44 is reversed to the line releasing posture. Thereby, the first bail support member 40 and the second bale support member 42 swing. In this state, the fishing rod is cast while catching the fishing line with the index finger of the hand holding the fishing rod. Then, the fishing line is released vigorously by the weight of the device. When the handle 1 is rotated in the line winding direction in this state, the rotor 3 is rotated in the line winding direction by the rotor driving mechanism 5 and the bail arm 44 is rotated.
Is returned to the line winding position by the bail reversing mechanism, and the fishing line is wound around the spool 4. In this state, when the drag is activated by the fish, the spool 4 rotates with respect to the spool shaft 15. Then, the first sounding mechanism 80 sounds and notifies the angler of the sound. Then, the spool 4 rotates in the line payout direction with the set drag force.

When fishing, the reel may be wet by waves or the like. Again, in this case,
Since the seal plate 71, the seal ring 72, and the O-ring 73 are mounted on the drag mechanism 60, water does not easily enter the fixing member 83. Further, since the waterproof member 58 is mounted on the spool 4, it is difficult for water to enter the inside of the front flange portion 54 from the mounting portion. For this reason, once the drag force is adjusted, the drag force is less likely to fluctuate due to water wetting.

[Other Embodiments] (a) In the above embodiment, two coil springs 66 and 67 are arranged in series with the elastic mechanism 62. However, the form of the elastic mechanism 62 is limited to the above embodiment. Not done. FIG.
Shows an example in which two coil springs 90 and 91 are arranged in series. Here, the spring constant k of the coil spring 90
1 is smaller than the spring constant k2 of the coil spring 91, and the free length of the coil spring 90 is longer than that of the coil spring 91. In this case, the two coil springs 90, 91
May be the same. With this configuration, as shown in FIG. 8, when only the coil spring 90 is compressed, the spring constant k of the elastic mechanism 62 becomes k1, and when the coil spring 91 also starts to be compressed, it becomes k1 + k2.

(B) In the above embodiment, the elastic mechanism 62 is constituted by a coil spring. However, as shown in FIG. 9, the elastic mechanism 62 may be arranged by disc springs 92 and 93 arranged in series. Further, a non-linear spring such as a bamboo shoot spring may be used. (C) In the above embodiment, the drag disk is non-rotatably mounted on the spool shaft. However, the disk mounted non-rotatably on the spool shaft and the disk non-rotatably mounted on the spool 4 are alternately arranged. Is also good.

According to the present invention, since the spring constant increases on the way, the drag force can be finely adjusted over a wide range by appropriately setting the spring constant of the elastic means. Therefore, an appropriate drag force can be set for fishing lines having different strengths. Therefore, the drag mechanism having the same structure can be adopted for two types of spools having different strengths, and the drag force can be finely set in a wide range for one spool.
