[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a device for preventing reverse rotation of a fishing reel. More specifically, the present invention is to prevent a reverse rotation of a rotor by a one-way bearing that rotates in one direction and maintain a constant tension of a fishing line.

[0002]

[Prior art]

 Generally, a reverse rotation prevention device is installed inside a fishing reel rotor to prevent the rotation of the rotor in the reverse direction, but the conventional reverse rotation prevention device is made up of a ratchet and a ratchet gear. The reverse rotation preventive device using such a ratchet has to maintain the strength of the ratchet gear teeth to withstand the tension of the fishing line. It is formed up to about individual pieces.

[0003] That is, when the number of teeth is large and the distance between the teeth is small, the rotational gap of the rotor is small. However, when the distance between the teeth is small, the strength of the gear is weakened, and the fish can be caught. In order to prevent the teeth from being damaged by the pulling force when the fishing line is tensioned, such as when fishing or catching on a reef, most are made large enough to maintain the strength of the teeth It is known.

However, since the larger the size of the teeth, the larger the distance between the teeth, the relative distance between the teeth with the ratchet locked with the teeth increases depending on the distance to the next tooth. Since the reverse rotation is performed just because the rotation gap is generated, the tension of the fishing line cannot be maintained at a constant value. In addition to this, there were problems such as not being able to accurately detect the hit state of the fish.

[0005]

[Problems to be Solved by the Invention] The present invention is to solve the above-mentioned problems of the prior art, and an object of the present invention is to prevent reverse rotation of a rotor by a one-way bearing that rotates in one direction. Accordingly, it is an object of the present invention to provide a fishing reel reverse rotation preventing device capable of maintaining a constant fishing line tension.

[0006]

[0007]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings. 1 and 2 are sectional views showing an embodiment of a device for preventing reverse rotation of a fishing reel according to the present invention. A drive shaft tube 2 is rotatably inserted and installed outside the spool shaft 1, and a rotor 3 is rotatably installed at a distal end portion of the drive shaft tube 2, and is integrally formed with a distal end portion of the drive shaft tube 2. A face gear 6 that rotates by rotating a handle (not shown) is meshed with the helical gear 4.

A sleeve 7 is inserted and installed outside the drive shaft tube 2, and a one-way bearing 8 that rotates in one direction is inserted and installed outside the sleeve 7, and a large number of outer circumferential edges are provided outside the one-way bearing 8. A rotating body 10 in which a plurality of locking grooves 9 are arranged at a fixed angle is extrapolated by forcible fitting, and a one-way bearing 8 and a rotating body 10 including a sleeve 7 are provided in front of the rotating body 10. A housing 15 for preventing the housing 15 from being detached forward is fixedly installed.

A first locking port 11 inserted into the locking groove 9 of the rotating body 10 to prevent rotation of the rotating body 10 is provided at a predetermined position outside the rotating body 10 with a spring interposed therebetween. The end of the first locking port 11 is rotated by a predetermined angle at a predetermined position behind the reel body 5 so that the tip of the first locking port 11 is locked by the locking groove of the rotating body 10. 9, an operation lever 12 is provided to prevent the rotor 3 from rotating in the reverse direction.

FIGS. 3 and 4 show another embodiment of the present invention, in which a rotating body 10 on which a one-way bearing 8 as the reverse rotation preventing means is installed and an operation lever 12 for fixing the position of the rotating body 10 are provided. Another rotating body locking means is further provided below the rotating body 10 of the installed fishing reel.

At a predetermined position of the rotating body 10, a second locking port 13 inserted into the locking groove 9 of the rotating body 10 to stop the rotation of the rotating body 10 is installed. On the side, the second locking port 13 is rotated only by a predetermined angle, so that the second locking port 13 can be selectively inserted into and removed from the locking groove 9 of the rotating body 10.

The operation of the present invention constructed as above will be described as follows. First, the operational relationship of the one-way bearing 8 will be described with reference to FIGS. The one-way bearing 8 has an operating space 8d formed in a retainer 8c that supports the roller 8e so that the roller 8e can move in the circumferential direction only at a predetermined interval, and has an outer ring 8a installed outside the retainer 8c. An operation groove 8b is formed on the inner peripheral edge so that the roller 8e can move vertically only within a predetermined gap, but a groove is formed deep in a direction in which the operation groove 8b can rotate, and a direction in which rotation is impossible. Has a low groove.

When the sleeve 7 rotates in the opposite direction as shown in FIG. 5A, the roller 8e moves in the direction in which the depth of the operation groove 8b decreases, and the roller 8e moves in the direction of the operation groove 8b. Is wedge-shaped between the low-depth portion and the outer surface of the sleeve 7 so that rotation in the direction in which the depth of the operating groove 8b is low becomes impossible. When the sleeve 7 rotates in the forward direction as shown in FIG. 5B, when the sleeve 7 rotates in the direction in which the depth of the groove is deep, the roller 8e is placed in the operation groove 8b in the direction in which the depth of the groove is deep. When the roller 8e is positioned, the rotation of the roller 8e becomes smooth, and the roller 8e can be rotated in a direction in which the depth of the groove is deep.

The manufacture and operation of the one-way bearing 8 are described with reference to the one-way bearing 8 itself. As described above, the rotating body 10 installed on the outer peripheral edge of the one-way bearing 8 is locked. Since the sleeve 7 can rotate in one direction, the sleeve 7 is inserted inside the one-way bearing 8 and refers to a rotating shaft that rotates.

According to the present invention in which the one-way bearing 8 acting as described above is installed, when the respective operating levers 12 and 14 are not operated, the first locking port 11 and the second locking port 13 are rotated. Since the fishing line is not locked in the locking groove 9, the direction in which the fishing line is wound and the direction in which the fishing line is unwound are all freely rotatable. The rotor 3 thus rotated can freely rotate in the direction of winding and unwinding the fishing line.

That is, since the first locking port 11 and the second locking port 13 are not inserted into the locking grooves 9 of the rotating body 10, the rotating body 10 is in a free state in which it is not restrained. When the shaft tube 2 is rotated in the forward direction or the reverse direction, the roller 8e of the one-way bearing 8 moves to the lower side of the groove 8b where the roller 8e of the one-way bearing 8 cannot rotate, and is inserted in a wedge type. However, since the rotating body 10 is not restricted, the rotating body 10 can rotate in both directions in the same direction as the drive shaft tube 2 rotates.

When the rotating body 10 is not restrained without operating the respective operating levers 12 and 14 as described above, the drive shaft tube 2 can rotate in both directions, and the front end of the drive shaft tube 2 The installed rotor 3 is in a state where it can rotate in both directions.

In order to prevent the rotor 3 from rotating in the reverse direction when the fish is hooked on the fishing hook in such a state, each of the operation levers 12 and 14 is operated to operate the first lever of the operation lever 12. The stopping port 11 and the second locking port 13 of the lever 14 are locked in the locking groove 9 of the rotating body 10 and restrain the rotating body 10 so that the rotating body 10 cannot be rotated. Although it has been described that all the two locking ports are locked in the locking groove 9, even if all the two locking ports are locked, only one of the two locking ports is locked. Even if the rotating body 10 is locked in the groove 9, the rotating body 10 cannot rotate.

In the state where the rotation of the rotating body 10 becomes impossible as described above, the operation principle of the one-way bearing 8 is the same as that of the one-way bearing 8 described above. It is as follows.

The drive shaft tube 2 rotates in the opposite direction as shown in FIG. 5A in a state where the rotating body 10 cannot be rotated by the first locking port 11 and the second locking port 13. When the handle is rotated, the drive shaft tube 2 and the sleeve 7 are moved by a minute amount in the direction in which the drive shaft tube 2 and the sleeve 7 are rotated, and the roller 8e is formed on the inner peripheral edge of the outer ring 8a while moving. The wedge-shaped groove 8b is wedge-shaped between the position where the depth of the groove 8b is low and the outer surface of the sleeve 7 while finely moving in the direction in which the depth of the groove 8b is low. It becomes impossible to rotate in the low direction. At this time, the rotation amount of the drive shaft tube 2 and the sleeve 7 is a minute amount corresponding to the width of the operation groove 8b formed on the inner peripheral edge of the outer ring 8a.

When the rotor 3 is allowed to rotate in both the forward and reverse directions in the state where the reverse rotation is disabled as described above, each of the first When the respective operating levers 12 and levers 14 are operated so that the locking port 11 and the second locking port 13 are disengaged from the locking groove 9, the drive shaft tube 2 including the rotating body 10 is moved. The rotor 3 is free to rotate in both directions with no restraining force.
