In the detailed description and claims of the invention related to other drawings, the direction is specified and described according to this standard, unless otherwise specified.

Hereinafter, a fishing reel having a potential corrosion preventing means according to the present invention will be described with reference to the accompanying drawings.

As shown in Figures 1a, 2a to 7b, the present invention relates to a fishing reel having a clutch means using a pinion to move back and forth, the frame 10 (more rigid) to rotate largely the spool 11 The spool shaft 20, which is built up on both side covers 12 and 13, is coupled backward and forward in the longitudinal direction from the spool shaft 20, and pinions 30 and pinions for controlling on/off clutch operation. It includes a first rolling member 40 and the pinion 30 and the first rolling member (40) for rolling support of the body portion 32 of the 30, the potential corrosion preventing means for selectively contact or non-contact.

The spool shaft 20 is coupled through the spool 11, both ends are built up on the side cover 12, 13 of the frame 10.

In this spool shaft 20, both side shaft portions are extended to both sides of the spool 11, and one side shaft portion 21 connected to the tension force adjusting portion W of the tension nut 15 has a second side cover 13 It is formed longer than the other shaft portion directly connected to.), and the spool 11 is extrapolated to the main shaft between the shaft portions to function as a rotating shaft for rotation of the spool 11.

In addition, the spool shaft 20 is coupled in a direction in which the fastening pin 22 is orthogonal to the longitudinal direction between the main shaft and the first shaft portion 21, and the fastening pin 22 is an outer peripheral surface of the first shaft portion 21 Is protruding from.

The pinion 30 is formed by a hollow portion 31 through which the spool shaft 20 (more precisely, the first shaft portion 21) is extrapolated in the longitudinal direction, and a clutch of clutch means including a yoke 17 The rotation of the spool shaft 20 is controlled on/off by moving back and forth in the longitudinal direction of the shaft through a bar operation.

Specifically, the pinion 30 is composed of a body portion 32 and a head portion 33 formed through the hollow portion 31, a drive interlocking with the handle 14 on the outer peripheral surface of the middle portion of the body portion 32 A gear part (32a) to which the gear (16) is meshed is protrudingly connected to one side, and the fastening pin (22) is inserted into the front end part (left side in the drawing) of the head part (33) to form a fitting part (33a). ) Is provided.

In the pinion 30, the fitting portion 33a is engaged with the fastening pin 22 in the state of being advanced by the yoke 17 by the pressurization of the clutch bar, and the spool shaft 20 and the pinion 30 are engaged. Constrained to the engaged drive gear 16, so that the spool 11 is rotated only by the handle 14 (clutch on state),

When the pinion 30 is retracted by the yoke 17 by releasing the clutch bar, the fitting portion 33a is separated from the fastening pin 22 while restraining the spool shaft 20 and the pinion 30. Release, so that the spool shaft 20 and the pinion 30 do not rotate in cooperation (i.e., only the spool shaft 20 is idle with respect to the pinion 30) so that the spool 11 is freely rotated (clutch off state) ).

In such a spool shaft 20, both sides of the shaft are fitted into a rolling member such as a bushing or a bearing to reduce friction during rotation. At this time, in the conventional fishing reel, the pinion 30 is extrapolated to the first shaft portion 21 and the first shaft portion ( The first rolling member provided along the periphery of the rear end (outer end of the toothed part 32a) 32 of the pinion 30 into which the first shaft portion 21 is fitted, because the 21) cannot be directly supported by the rolling member. 40) to support the first shaft portion (21).

In this conventional fishing reel, when the pinion 30 rotates with the spool shaft 20, the pinion 30 and the first rolling member 40, which are all metal materials, are in constant contact as shown in FIG. 1B. , Due to friction caused by rotation of the pinion 30, a potential difference occurs between the pinion 30 and the first rolling member 40, and potential corrosion occurs on the contact surface between the pinion 30 and the first rolling member 40. As this occurs, there is a problem in that the pinion 30 does not move back and forth in the longitudinal direction of the spool shaft 20 and is stuck.

Accordingly, the present invention provides a potential corrosion preventing means to naturally space between the pinion 30 and the first rolling member 40 so as to be in contact with each other during the fishing or maintenance of the fishing reel, the pinion 30 and the first. The potential difference between the rolling members 40 is resolved to prevent the occurrence of potential corrosion.

Specifically, the potential corrosion preventing means of the present invention is to allow the body portion 32 to selectively contact or non-contact the first rolling member 40 during the front-rear operation of the pinion 30.

2a to 5b, the first pin member 30 is in the clutch-on state in which the pinion 30 is advanced in the spool direction, so that the first rolling member 40 makes no contact with the body portion 32,

It characterized in that the pinion 30 is in the clutch off state in the reverse direction of the spool, the first rolling member 40 is in contact with the body portion 32,

6A to 7B, the first rolling member 40 makes contact with the body portion 32 in the clutch-on state in which the pinion 30 is advanced in the spool direction,

It is characterized in that the first rolling member 40 makes the torso 32 non-contact with the pinion 30 in the clutch off state in the reverse direction of the spool.

That is, in the first embodiment, the pinion 30 is in contact with the first rolling member 40 in the clutch-on state, so that the first rolling member 40 indirectly supports the pinion 30, and the pinion 30 is in the clutch off state. ) Is in contact with the first rolling member 40, the first rolling member 40 directly supports the pinion 30,

Conversely, in the second embodiment, the pinion 30 is indirectly supported by the non-contact with the first rolling member 40 in the clutch off state, and the pinion 30 is directly supported by contacting the first rolling member 40 in the clutch on state. do.

Therefore, even when the potential difference due to friction between the pinion 30 and the first rolling member 40 occurs during the use of the fishing reel, the user repeatedly moves the pinion 30 back and forth using a clutch bar when fishing or repairing the fishing reel. , Even if there is no additional work, the potential difference is naturally resolved as the pinion 30 is repeatedly contacted with the first rolling member 40 while moving back and forth to prevent the occurrence of potential corrosion.

Hereinafter, an implementation example for each embodiment will be described in detail.

First, the potential corrosion preventing means of the first embodiment shown in Figures 2a to 4b,

The first contact portion (34a) provided on the outer peripheral surface of the body portion 32,

A first non-contact portion 34b having an outer diameter smaller than the outer diameter of the first contact portion 34a, provided to be connected to the rear end side of the first contact portion 34a.

Is provided on the inner circumferential surface of the first rolling member 40, including a first support portion (41a) having an inner diameter corresponding to the outer diameter of the first contact portion (34a),

In the clutch-on state, the first non-contacting portion 34b is non-contacting the first support portion 41a,

In the clutch off state, the first contact portion 34a is in contact with the first support portion 41a.

That is, the outer diameter of the middle portion (first contact portion 34a) of the trunk portion 32 provided with the tooth portion 32a of the pinion 30 and the inner diameter of the first rolling member 40 correspond to each other, By making the outer diameter of the rear end portion of the trunk portion 32 (first non-contact portion 34b) smaller than the outer diameter of the first contact portion 34a,

In the state in which the pinion 30 is advanced, the first non-contacting portion 34b is positioned on the same line as the inner first supporting portion 41a of the first rolling member 40 so as not to contact the first rolling member 40,

In the state in which the pinion 30 is retracted, the first contact portion 34a is positioned on the same line as the inner first support portion 41a of the first rolling member 40 so as to contact the first rolling member 40.

At this time, the tolerance G1 between the outer diameter of the first contact portion 34a (the inner diameter of the first support portion 41a) and the first non-contact portion 34b is approximately 0.1 to 0.5 mm.

For reference, in this specification, the contact between the pinion 30 and the first rolling member 40 is not exactly the same as the outer diameter and the inner diameter of the contact area, and the outer diameter and inner diameter of the contact area are fine tolerances for assembling male and female (approximately). 0.01~0.03mm), which means a micro-contact state, and thus, in this specification, it is described as having a diameter corresponding to each other without explaining that the outer diameter and the inner diameter of the contact area have the same diameter, and thus interpret the right for this. This should not be limited.

In the present invention, when the pinion 30 is operated forward or backward while fishing or repairing the fishing reel, contact or non-contact with the first rolling member 40 occurs repeatedly and naturally, thereby preventing corrosion due to potential difference.

In addition, even when a strong tension is applied to the spool 11 when the spool 11 is rotated with the handle 14 in the clutch on state as shown in FIG. 2A, the tolerance between the first non-contact portion 34b and the first support portion 41a Due to (G1), the load transmitted to the teeth 32a and the drive gear 16 is engaged, so that damage to the gear can be prevented.

In addition, when casting in the clutch off state as shown in FIG. 2B, the pinion 30 due to vibration caused by rotation of the spool 11 as the body 32 of the pinion 30 is fixed by the first rolling member 40 ) Does not fluctuate (shake), so that the interference phenomenon between the spool shaft 20 and the pinion 30 does not occur, thereby improving the flying distance of the casting.

Further, even if the spool shaft 20 is removed from the clutch on state and the handle 14 is rotated for maintenance of the fishing reel as shown in FIG. 2C, the first rolling member 40 in a fine non-contact state is the pinion 30. The vibration of the first non-contact portion (34b) and the first support portion (41a) within the tolerance (G1) by suppressing to a minimum, the toothed portion (32a) and the drive gear 16 can be prevented from being damaged have.

As a modification of the first embodiment, as shown in FIGS. 3A to 4B, the first rolling member 40 has an inner diameter larger than the outer diameter of the first contact portion 34a, and the first support portion ( 41a) is characterized in that it comprises a protruding first support protrusion (41c).

That is, the inner diameter (first unsupported portion 41b) of the first rolling member 40 is made larger than the outer diameter of the middle portion (first contact portion 34a) of the trunk portion 32, and the first contact portion 34a A pinion (30) is formed on the inner circumferential end of the first support protrusion (41c) protruding by a tolerance (G1) on the inner circumferential surface of the first rolling member (40) with an inner diameter corresponding to the outer diameter of the first rolling member (40). ), the contact or non-contact of the first contact portion 34a and the first support portion 41a is made according to the forward and backward movement.

At this time, there is no limitation on the position of the first support protrusion 41c on which the first support part 41a is formed, and accordingly, in FIGS. 3A and 3B, the first support protrusion 41c is formed at the front end of the inner circumferential surface of the first rolling member 40. 4A and 4B, it can be seen that the embodiment in which the first support protrusion 41c is provided in the center of the inner circumferential surface of the first rolling member 40 is shown.

On the other hand, as shown in Figures 3a to 4b, the pinion 30 is provided to be connected to the rear end of the first non-contact portion (34b), the outer contact and the outer diameter of the first contact portion (34a) Includes section 34c.

That is, in the form of a groove having an outer diameter smaller than the outer diameter of the remaining outer circumferential surface in the middle of the outer circumferential surface of the rear end of the trunk portion 32 having an outer diameter corresponding to the inner diameter (first support portion 41a) of the first rolling member 40 Processing to form the first non-contact portion (34b) between the first contact portion (34a) and the engaging portion (34c), the first contact portion (34a) and the first support portion (41a) according to the forward and backward movement of the pinion (30) Allow contact or non-contact.

The engaging portion (34c) is for improving the assembly of the first shaft portion 21 and the first rolling member 40, the first diameter of the outer diameter smaller than the inner diameter of the first support portion (41a) without the engaging portion (34c) When the non-contact portion (34b) is provided at the rear end end portion of the body portion (32). This is to prevent the first shaft portion 21 from being fitted at an angle due to the tolerance G1 and not being correctly assembled.

Next, as another first embodiment of the present invention, as shown in Figures 5a and 5b, the potential corrosion preventing means,

The second contact portion 35 formed while the outer peripheral surface of the body portion 32 has the same outer diameter,

A second unsupported portion 42b provided on an inner circumferential surface of the first rolling member 40 and having an inner diameter larger than the outer diameter of the second contact portion 35,

While being connected to the rear end side of the second non-supporting portion (42b) is provided to protrude inward, including a second support portion (42a) having an inner diameter corresponding to the outer diameter of the second contact portion (35),

In the clutch-on state, the second contact portion 35 is not in contact with the second non-supporting portion 42b,

In the clutch off state, the second contact portion 35 is in contact with the second support portion (42a).

That is, unlike the embodiments in which the outer diameters of the body parts 32 shown in FIGS. 2A to 4B are different from each other, the embodiments of FIGS. 5A and 5B have the entire outer circumferential surface of the body parts 32 having the same diameter. The contact portion 35 is formed, and the inner circumferential surface of the first rolling member 40 is greater than the outer diameter of the second support portion 42a and the second contact portion 35 of the inner diameter corresponding to the outer diameter of the second contact portion 35. Formed in a two-stage structure made of a second non-supporting portion (42b),

The second contact portion 35 and the second support portion 42a are contacted or the second contact portion 35 and the second non-support portion 42b are non-contacted according to the forward and backward movement of the pinion 30.

At this time, the tolerance (G2) between the outer diameter of the second contact portion 35 (the inner diameter of the second support portion 42a) and the second non-supporting portion 42b is approximately 0.1 to 0.5 mm.

In addition, since the non-contact between the second contact portion 35 and the second non-supporting portion 42b has to occur in the clutch-on state in which the pinion 30 is advanced, the second support portion 42a is in the state where the pinion 30 is reversed. The first contact member 34a protrudes from the rear end of the first rolling member 40 so as to be arranged on the rear side rather than the rear end.

Next, the potential corrosion preventing means of the second embodiment shown in FIGS. 6A to 7B,

The third non-contact portion (36b) provided on the outer peripheral surface of the body portion 32,

The third contact portion (36a) having an outer diameter larger than the outer diameter of the third non-contact portion (36b) is provided to be connected to the rear end side of the third non-contact portion (36b),

Is provided on the inner peripheral surface of the first rolling member 40, including a third support portion (43a) having an inner diameter corresponding to the outer diameter of the third contact portion (36a),

In the clutch-on state, the third contact portion 36a contacts the third support portion 43a,

In the clutch off state, the third non-contacting portion 36b is characterized in that it does not contact the third supporting portion 43a.

That is, the outer diameter of the body portion 32 is smaller than the inner diameter (third support portion 43a) of the first rolling member 40 to form a third non-contacting portion 36b, and the third non-contacting portion 36b By forming the rear end portion to protrude to have an outer diameter corresponding to the inner diameter of the first rolling member 40, thereby forming the third contact portion 36a,

When the pinion 30 is advanced, the third non-contacting portion 36b is positioned on the same line as the inner third supporting portion 43a of the first rolling member 40 so as to contact the first rolling member 40,

In the state in which the pinion 30 is retracted, the third contact portion 36a is positioned on the same line as the inner third support portion 43a of the first cloud member 40 so as to contact the first cloud member 40.

At this time, the tolerance between the third non-contact portion 36b and the third support portion 43a (ie, the outer diameter tolerance of the third contact portion 36a and the third non-contact portion 36b is approximately 0.1 to 0.5 mm.

The second embodiment differs only in that contact or non-contact with the first rolling member 40 when the pinion 30 is moved back and forth is reversed from the first embodiment, and the trunk portion 32 is similar to the first embodiment. ) And the first difference of the potential difference through the repetitive separation of the rolling member 40 is made the same. The occurrence of potential corrosion due to the potential difference can be prevented.

However, in the second embodiment, as shown in FIGS. 6A and 7A, in contrast to the first embodiment, the body portion 32 of the pinion 30 is in contact with the first rolling member 40 in the clutch on state. Since the support portion 43a directly supports the third contact portion 36a, the pinion 30 that rotates together when the spool 11 is rotated through the handle 14 operation can be stably rolled.

In addition, in the second embodiment, as shown in FIGS. 6B and 7B, the body 32 of the pinion 30 is not in contact with the first rolling member 40 in the clutch off state, as shown in FIGS. 6B and 7B. The pinion 30 which does not rotate at the time may swing due to vibration, etc. In this case, the third support portion 43a of the first rolling member 40 has a third non-contact of the body portion 32 with a structure similar to that of FIG. 2C. Since the indirect support is provided by indirectly contacting the periphery of the portion 36b finely, the fluctuation of the pinion 30 can be minimized, and the difference between the inner diameter of the hollow portion 31 to be described later and the outer diameter of the first shaft portion 21 and The non-contact structure of the first shaft portion 21 and the pinion 30 does not occur through the non-contact structure of the fourth contact portion 37a and the fourth non-supporting portion 23b, thereby blocking the transmission of vibration, etc., thereby causing the pinion 30 to swing. Will not.

Furthermore, as a modification of the second embodiment, as shown in FIGS. 7A and 7B, the first rolling member 40 has an inner diameter larger than the outer diameter of the third contact portion 36a, but the third supporting portion ( 43a) is characterized in that it comprises a third support protrusion (43c) protruding.

That is, the inner diameter (third unsupported portion 43b) of the first rolling member 40 is made larger than the outer diameter of the rear end portion (third contact portion 36a) of the trunk portion 32, and the third contact portion 36a A third support portion 43a having an inner diameter corresponding to the outer diameter is formed on the inner end of the third support protrusion 43c protruding by a tolerance G2 on the inner circumferential surface of the first rolling member 40, before and after the pinion 30 The third contact portion 36a and the third support portion 43a are in contact with each other, or the third non-contact portion 36b and the third support portion 43a are not contacted.

At this time, the position of the third support protrusion 43c on which the third support part 43a is formed may vary according to the length of the section of the third contact part 36a (that is, the position at which the third non-contact part 36b starts). 7A and 7B show an exemplary embodiment in which the third support protrusion 43c is provided at the front end of the inner circumferential surface of the first rolling member 40.

Subsequently, a feature of internally supporting the pinion 30 of the present invention will be described.

First, as shown in Figure 2b, the inner diameter of the hollow portion 31 is formed larger than the outer diameter of the first shaft portion 21,

The spool shaft 20 includes a fourth non-supporting portion 23b provided on an outer circumferential surface of the first shaft portion 21, and a fourth non-supporting portion 23b at a middle portion of the fourth non-supporting portion 23b. It includes a fourth support (23a) protruding to have a larger outer diameter,

The pinion 30 has a larger inner diameter than the fourth contact portion 37a at the fourth contact portion 37a having an inner diameter corresponding to the outer diameter of the fourth support portion 23a, and at the middle portion of the fourth contact portion 37a. Including a fourth non-contact portion (37b) formed concave to have,

In the clutch-on state, the fourth contact portion 37a contacts the fourth support portion 23a,

In the clutch off state, the fourth non-contact portion 37b is characterized in that it does not contact the fourth support portion 23a.

That is, the inner diameter of the hollow portion 31 of the pinion 30 is larger than the outer diameter of the first shaft portion 21, and the outer peripheral surface of the first shaft portion 21 has an outer diameter corresponding to the inner diameter of the hollow portion 31 4 Protrudingly forming the supporting portion 23a, and forming a fourth non-contacting portion 37b in the form of a groove having an inner diameter smaller than the inner diameter of the remaining outer peripheral surface on a part of the outer peripheral surface of the hollow portion 31,

When the pinion 30 is advanced, the fourth contact portion 37a of the pinion 30 is located on the same line as the outer fourth support portion 23a of the first shaft portion 21, so that the hollow portion 31 is the first. The pinion 30 is directly supported by the spool shaft 20 while being in contact with the shaft portion 21, that is, the spool shaft 20,

In the state in which the pinion 30 is retracted, the fourth non-contact portion 37b of the pinion 30 is located on the same line as the outer fourth support portion 23a of the first shaft portion 21, so that the hollow portion 31 is made. The pinion 30 is indirectly supported by the spool shaft 20 while being in contact with the one shaft portion 21, that is, the spool shaft 20.

At this time, the inner diameter of the fourth contact portion (37a) and the outer diameter tolerance (G3) of the fourth non-supporting portion (23b) and the inner diameter of the fourth non-contact portion (37b) and the outer diameter tolerance of the fourth support portion (23a) is formed to 0.1 ~ 0.5mm do.

In this way, the pinion 30 of the present invention is provided with a contact avoiding section made of a fourth non-contact portion 37b,

In the clutch-on state, while minimizing the contact area between the first shaft portion 21 and the pinion 30, the first shaft portion 21 internally supports the pinion 30 and the spool shaft 20 and pinion ( 30) prevent the axis from twisting when rotating together,

In the clutch off state, the first shaft portion 21 and the pinion 30 are completely non-contact with each other, thereby preventing the main shaft rotating during casting from contacting or rubbing against the non-rotating pinion 30 so that the flying distance is not reduced. .

Next, as shown in Figure 2a, further comprising a second rolling member (40A) provided along the periphery of the head portion 33 of the pinion 30,

The inner diameter of the second rolling member (40A) is formed larger than the outer diameter of the head portion 33, characterized in that the pinion (30) and the second rolling member (40A) are not in contact with each other.

That is, as in the non-contact structure of the first rolling member 40 and the pinion 30, the inner diameter of the second rolling member 40A is formed to be larger than the outer diameter of the head part 33, so that the second rolling member 40A The head part 33 indirectly supports the outer circumferential surface.

At this time, the outer diameter of the second head portion 33 and the inner diameter tolerance G4 of the second rolling member 40A are formed to be 0.1 to 0.5 mm.

When the second rolling member 40A is provided as above, the potential difference caused by friction with the second rolling member 40A due to the rotation of the pinion 30 is prevented, and thus potential dislocation corrosion can be prevented from occurring in the corresponding area. ,

Furthermore, as illustrated in FIG. 2C, the spool shaft 20 can be removed from the clutch on state and the pinion 30 can be rotated by the handle 14 for maintenance of the fishing reel. If there is no second rolling member 40A, the head portion As there are no parts supporting the outer circumferential surface of (33), the first and second clouds may be damaged while the front end portion of the pinion 30 swings and the engagement portion of the tooth portion 32a and the drive gear 16 is damaged. Through the members 40 and 40A, the front and rear ends of the pinion 30, i.e., the body portion 32 and the head portion 33, are indirectly supported by two points, respectively, so that the pinion 30 is rotated when the pinion 30 is rotated alone. By suppressing the shaking, it is possible to simultaneously prevent the pinion 30 from sticking and the effect of supporting the pinion 30.

In the above description of the present invention with reference to the accompanying drawings, a fishing reel having a potential corrosion prevention means has been mainly described, but the present invention can be variously modified, changed, and replaced by those skilled in the art. It should be interpreted as belonging to the protection scope of the present invention.
