Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to the mounting structure of the bail hinge in a spinning reel. This invention relates to a variable mounting structure.

(Prior Art) A bail hinge in a conventional spinning reel is a shaft that is rotatably attached to one of a pair of arms that protrude oppositely on the diameter line of the fryer, which is driven by the rotation of the handle. At the same time, a bail return spring is stretched across the bail hinge and the arm portion, and the bail hinge is urged to roll to a position where the fishing line can be locked and a release position where the fishing line can be released. There is.

A line roller for hooking a fishing line is attached to the bail hinge so that it can freely rotate around the roller shaft, and the fishing line is hooked onto the inner peripheral surface of the line roller and reciprocated back and forth around the spool. The fishing line is wound around the spool by rotating the spool.

By the way, since the above-mentioned bail hinge is pivotally supported in a fixed position with respect to the arm by a set screw, the winding width generated in relation to the back and forth reciprocation of the spool is constant, so the thickness of the fishing line used ( If the number of fishing lines changes, the way the fishing line is wound onto the spool changes, causing problems such as when the fishing line is wound in a mountain or valley shape.

Therefore, we corrected the uneven winding of the fishing line,
A device that moves the spool back and forth has been proposed as an adjustment means for flatly winding the spool around the body of the spool, but its structure is complex and requires time and effort to assemble, resulting in high costs. .

(Problems to be Solved by the Invention) In view of the above-mentioned conventional circumstances, the present invention is capable of responding to the position adjustment of the spool, which has a complex structure and requires time and effort to assemble, by changing the position of the bail hinge. It is in.

(Means for Solving the Problems) The technical means of the present invention for solving the above problems is to rotate an eccentric cam between the through hole of the bail hinge which is pivotally supported by a set screw in the arm and the set screw. mating possible.

(Function) According to the above means, the eccentric cam fitted into the through hole of the bail hinge is opened with the center of the screw fitting hole through which the set screw is inserted eccentrically relative to the center of the outer diameter of the eccentric cam. By adjusting the rotation of the eccentric cam, the bail hinge is moved back and forth along the axis of the spool, and the position of the line roller changes back and forth. As a result, the winding width generated in relation to the back and forth reciprocating motion of the spool can be widened or narrowed, and the winding state of the fishing line can be flattened.

(Embodiment) Hereinafter, an embodiment of the present invention will be described based on the drawings. In the drawing, 1 is an arm portion formed in series with a fryer (not shown), 2 is a bail hinge, 3 is an eccentric cam, and 4 is a The set screw 5 is a line roller.

The arm portion 1 has a recess 6 that opens outward, has a screw hole 7 in the center into which a set screw 4 is screwed, and has a screw hole 7 around the outside of the screw hole 7 that restricts the rotation range of the bail hinge 2. A stopper 8 is formed to protrude.

The bail hinge 2 includes a disk portion 2a and the disk portion 2a.
A through hole 9 is drilled through the center of the disc part 2a, and an arcuate guide groove 10 is cut out on the back surface of the disc part 2a. In addition, a bail return screw 11 is hooked across the back surface of the disc portion 2a and the arm portion 1. Further, a line roller 5 is supported on the protrusion 2b of the bail hinge 2 by a roller shaft 12 and a roller shaft set screw 13, and one side end of the bail 14 is fixed to the roller shaft 12.

The eccentric cam 3 is a circular plate made of a synthetic resin material and has the same diameter as the through hole 9 of the bail hinge 2 and the same thickness as the depth of the through hole 9. The eccentric cam 3 is a circular plate made of a synthetic resin material and has a center located eccentrically from the center of the outer diameter. As the large diameter shaft portion 4a of the set screw 4
A screw fitting hole 15 into which the screw fitting hole 15 is fitted is drilled through the eccentric cam 3, and the eccentric cam 3 is operated by being positioned on the line connecting the outer diameter center of the cam and the center of the screw fitting hole 15 on the upper outer peripheral surface of the eccentric cam 3. A lever 16 is integrally formed to protrude.

The set screw 4 is a stepped screw and has a threaded rod portion 4b formed at the tip thereof to be screwed into the screw hole 7 of the arm portion 1, and a large diameter shaft portion 4a on the base side supports the bail hinge 2 via the eccentric cam 3. , the bail hinge 2 and the eccentric cam 3 are prevented from coming off by the head 4c.

Further, a moderation convex portion 17 is protruded from the back surface of the operating lever 16 connected to the above-mentioned eccentric cam 3, and is fitted into moderation concave portions 18a and 18b formed at a predetermined interval on the upper surface of the bail hinge 2. By doing so, the rotation of the eccentric cam 3 can be adjusted with good moderation. It should be noted that the above-mentioned adjustment moderation stages are not limited to the two stages shown in the drawings, and may of course be set to more than two stages as desired.

In the figure, 19 is a cover that closes the upper surface of the recess 6 of the arm portion 1, and 20 is a cover set screw.

Next, to explain how to adjust the position of the bail hinge 2, when the eccentric cam 3 is set as shown in FIG. The radial center is located at a position shifted downward from the center of the set screw 4. To move the bail hinge upward from this state, rotate the operating lever 16 of the eccentric cam 3 clockwise around the set screw 4, and the center of the outer diameter of the eccentric cam 3 will move upward from the state shown in Figure 1. Due to the movement, the position of the bail hinge 2 also moves to the position shown by the imaginary line in FIG.

(Effect of the invention) As described in detail above, the bail hinge mounting structure of the present invention has a through hole that is larger in diameter than the axial diameter of the set screw, is drilled in the disc part of the bail hinge, and the through hole is inserted into the through hole. The screw fitting hole for the set screw is drilled at a position eccentric from the center of the outer diameter, and the eccentric cam with a control lever protruding from the outer circumferential surface can be rotated and adjusted. The set screw is screwed into the arm through the screw fitting hole, so when the eccentric cam is rotated, the center position of the through hole of the bail hinge moves on the arm from the base to the outside. and the position of the line roller attached to the bail hinge changes.

Therefore, by adjusting the rotation of the eccentric cam according to the thickness (number) of the fishing line used or the winding state of the fishing line, it is possible to establish a flat winding.

Furthermore, since its structure is simply that an eccentric cam is fitted to the bail hinge, it is much simpler than conventional spool position adjusting devices, and it is very easy to assemble and can be manufactured at low cost. It's something you get.
