Description

Centrifugal brake backlash prevention device for fishing double bearing reel

The present invention relates to a centrifugal brake back lash preventing device of a fishing double bearing reel for preventing backlash of a fishing double bearing reel by using the centrifugal force of the spool when the spool rotates, in particular, a problem that parts are damaged. The present invention relates to a centrifugal brake back lash preventing device for a fishing double bearing reel that is removed, is easy to operate, and is easy to repair.

When fishing using both fishing reels for fishing, the reel main body is held together with the fishing rod and the bait is caught. As a result, the fishing line wound on the spool of the reel is released. At this time, the fishing line is drawn with a parabolic line, and as the fishing line falls past the convex vertex of the parabolic line, the acceleration is attached to the spool wound around the fishing line. As a result, the circumferential speed of the spool is faster than the speed at which the fishing line is released, so that a so-called "backlash" phenomenon occurs. As such, when the backlash occurs, the problem that the fishing line is not entangled in the reel often occurs. To prevent this backlash, skilled people press the upper part of the spool where the fishing line is wound with a finger, usually the thumb, so that the circumferential speed of the spool is approximately equal to the speed at which the fishing line is released. Make it smaller. However, since such a method is a rather difficult operation for an inexperienced person, some anti-backlash devices have been developed to solve this problem.

1 and 2 schematically show a device for preventing centrifugal brake backlash of a conventional fishing double bearing reel. The spool 12 is located in the reel unit 10. One end of the spool shaft 14 of the spool 12 that rotates as the handle 18 rotates is supported by a support hole (not shown) in the reel body 10 and the other end is supported in the cover 16. It is supported by the hole 20. The centrifugal brake anti-backlash device includes a plurality of grooves 32 formed at one end of the spool shaft 14 of the spool 12 so as to rotate as the spool 12 rotates and formed along its outer circumferential surface. A rotation member 30 having pins 34 extending in the outer radial direction of the center, and moving radially outward by a centrifugal force acting on the rotation member 30 to cover one side of both bearing reels. It is composed of a brake shoe 50 is slidably fitted on the pin 34 so as to be in contact with the brake drum 40 provided in the cover 16 and a flange 50a is formed on its lower side. have.

When the fishing line is released, the spool 12 is rotated, and as the spool 12 rotates, the rotating member 30 fitted to the spool shaft 14 of the spool 12 rotates. At this time, when the rotating member rotates at a speed equal to or higher than a specific speed, the brake shoe 50 fitted on the pin 34 of the rotating member 30 is radially outward by the centrifugal force of the rotating member 30. Will be moved to. The end of the brake shoe 50 moved as described above comes into contact with the inner surface of the brake drum 40 provided in the cover 16. As such, the rotational speed of the spool 12 is reduced by the frictional force caused by the contact between the brake shoe 50 and the brake drum 40 to prevent backlash. When the fishing line is thrown hard and the rotational speed of the rotating member 30 is increased, the centrifugal force acting on the rotating member 30 corresponds to that, so that the brake shoe 50 and the brake drum 40 are in contact with each other. The frictional force is also increased to effectively prevent backlash. However, when it is necessary to change the friction force according to the user's usage habits, some or all of the plurality of brake shoes 50 are fixed to prevent movement toward the brake drum 40. To this end, in the embodiment shown in Figure 1 by pressing the flange (50a) formed on the lower side of the brake shoe 50 to the lower side of the latching jaw (12a) formed on one side of the spool 12 to hold the flange 50a Position it below the jaw 12a. At this time, the flange 50a is positioned below the latching jaw 12a by its elasticity, but in this process, the flange 50a is frequently damaged. The same problem occurs when the brake shoe 50 is pulled out again from the locking step 12a. On the other hand, as shown in Figure 2, when the locking jaw (12a) is formed in the rotating member 30, the locking jaw (12a) may be broken, in this case, the entire rotating member 30 or Since the whole spool 12 needs to be replaced, the cost of parts increases. 1 and 2, the upper stopper 38 is formed at both sides of the opening of the groove 32 to prevent the brake shoe 50 from escaping from the groove 32. Even when the brake shoe 50 is initially inserted into the pin 34 through the upper stopper 38, the work is inconvenient and the flange 50a of the brake shoe 50 is often broken.

Accordingly, an object of the present invention is to provide a centrifugal brake for a fishing double bearing reel, in which the brake shoe or the rotating member is not damaged and is easily repaired during operation of the brake shoe used in the centrifugal brake backlash prevention device of the double bearing reel for fishing. It is to provide an anti-backlash device.

The centrifugal brake backlash prevention device for a fishing double bearing reel according to a preferred embodiment of the present invention for achieving the above object is fitted with its own center on one end of the spool shaft of the spool so as to rotate as the spool rotates. In the cover which covers the one side of the said both bearing reel and the rotating member which has the pin which respectively extends in the outer radial direction of the said center in the several groove | channel formed along, and moves radially outward by the centrifugal force acting on the said rotating member. A centrifugal brake backlash prevention device for a fishing double bearing reel composed of a brake shoe which is slidably fitted on the pins so as to be rubbed in contact with a provided brake drum and a flange is formed on a lower side thereof. Radially outward of the brake shoe by centrifugal force Only one upper stopper is formed at one side of the opening of the groove to prevent the brake shoe from escaping from the pin when moving, and the radius on the pin is caused by the centrifugal force of the rotating member when each brake shoe is not used. And an o-ring rotatably fitted on an axis formed on said rotating member to prevent movement outwardly.

With reference to Figures 3 and 4 will be described in detail the backlash prevention device of the fishing bearing bearing reel according to a preferred embodiment of the present invention.

3 and 4 schematically show a centrifugal brake backlash prevention device for a fishing double bearing reel according to a preferred embodiment of the present invention. Only one upper stopper 38 is formed in the opening of the groove 32 formed in the rotating member 30. A shaft 60 protrudes from the upper surface 31 of the rotating member 30. As shown in FIG. 4, the upper surface 31 has a stage formed downward. On the shaft 60 an o-ring 62 is fitted to allow rotation on the shaft 60. The o-ring 62 is made of rubber, but may be made of another material having elasticity.

As mentioned above, since only one upper stopper 38 is formed in the opening of the groove 32 formed in the rotating member 30, the flange 50a of the brake shoe 50 is formed by the upper stopper 38. Less interference. This makes it easy to fit the brake shoe 50 onto the pin 34. In addition, in order to control the friction force between the brake shoe 50 and the brake drum 40, in order to block the brake shoe 50 from contacting the brake drum 40, the brake shoe 50 is grooved ( 32) to the lower side of the groove. When the brake shoe 50 is pressed downward of the groove 32, the flange 50a of the brake shoe 50 presses the o-ring 62, and the o-ring 62 itself. It is slightly pressed in the direction of the axis 60 by the elasticity of the. At the same time, the o-ring 62 is rotated on the shaft 60, so that the brake shoe 50 is positioned below the groove 32. As a result, an excessive force is not applied to the flange 50a of the brake shoe 50, thereby preventing damage to the flange 50a. On the contrary, when the brake shoe 50 is pulled out above the groove 32, the o-ring acts similarly to prevent the brake shoe 50 or the rotating member 30 from being damaged.

As described above, the centrifugal brake backlash preventing device of the fishing double bearing reel according to a preferred embodiment of the present invention is adapted to change the position of the brake shoe so that the brake shoe may or may not generate frictional force with respect to the brake drum. There is an effect that the brake shoe or the rotating member is prevented from being damaged. In addition, when the brake shoe is initially fitted on the pin of the rotating member, there is an advantage that the assembling work becomes easy since only a slight interference is caused by one upper stopper.
