Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an angle adjusting mechanism of a fishing line guide roller in a spinning reel.

[Prior Art] Generally, a spinning reel drives a spool provided slidably on a reel body (not shown) by a handle (not shown) and a rotor rotatably provided at a front portion of the reel body to a fishing line on the spool. Is configured to be wound up.

As shown in FIG. 1, the rotor is provided with arms 25, 25 at substantially symmetrical positions on both sides, and a bail arm lever 1 and a bail arm rotatably supported at the front ends of the arms 25, 25. Both ends of the bail arm 23 are axially supported by the holder 28, and the fishing line is wound around the spool 12 while the fishing line is guided by the guide roller 4 axially supported by the bail arm lever 1.

However, the fishing line guide roller 4 in the conventional spinning reel has a base portion 1a and an end portion 1b of the bail arm lever 1 whose tip is formed in a substantially U-shaped portion as shown in FIGS. 2 and 3.
As shown in FIG. 1, since a drum-shaped member having a thread guide groove formed around the outer peripheral surface of a cylindrical body is rotatably supported by a shaft pin 7 whose both ends are positioned. As described above, the fishing line wound on the spool 12 is guided by the guide roller 4 at a right angle β at the winding outer diameter r which is the middle of the maximum winding length of the fishing line of standard thickness wound on the spool 12. Further, when the shaft pin 7 is positioned at the base portion 1a and the end portion 1b, the fishing line wound on the spool 12 with a winding outer diameter R larger than the intermediate winding outer diameter r is With respect to the roller 4, at an angle offset from the right angle β by an angle α,
In addition, the spool is in contact with the upward-sloping surface of the guide roller 4.
Since the twelve guides are provided, the fishing line itself rolls in the right direction and is twisted in the clockwise direction to be wound up.

On the contrary, the fishing line wound on the spool 12 with the winding outer diameter r ₁ smaller than the intermediate winding outer diameter r is brought into contact with the right upward surface of the guide roller 4 for the same reason as described above. Then, the yarn is twisted in the counterclockwise direction and wound.

Therefore, in such a reel, if the fishing line having the standard thickness is wound on the spool 12 for the maximum winding length and the entire amount of the wound fishing line is constantly thrown, the winding outer diameter r in the middle of Since the counterclockwise twist and the clockwise twist inside and outside of the fish are almost canceled out, problems such as fishing line clogging and line breakage at the time of throwing the fishing line due to the line twist hardly occur.

However, in actual fishing, it is unlikely that the entire amount of the wound fishing line will be thrown, and in some cases, a fishing line thinner than the standard thickness of the fishing line may be wound for a longer time than the intermediate winding diameter r. In many cases, fishing is performed mainly on the outer side, or fishing is performed centering on the inner side of the intermediate winding diameter r without winding the fishing line up to the maximum winding diameter R of the fishing line. The above-mentioned clockwise and counterclockwise twists of thread are unbalanced, and only one twist of thread is accumulated, and the problem based on the above-mentioned thread twist becomes apparent.

As a solution to this problem, the techniques disclosed in Japanese Utility Model Publication No. 49-30149 and Japanese Utility Model Publication No. 57-89471 have been proposed. However, in the former case, the fishing line wound on the spool is wound. It is theoretically ideal because the guide roller rotates in accordance with the fishing line guide direction that accompanies changes in the take-up diameter, and the fishing line guide angle changes, but the guide roller becomes unstable. Besides, there is a problem that not only is there difficulty in hooking the fishing line at the start of winding, but also a problem that the line easily breaks down due to intrusion of foreign matter.

Further, the latter is to adjust the mounting angle of the guide roller by loosening the screw according to the guide direction of the fishing line to the spool, so the angle adjustment is not only troublesome and time consuming, but also the guide roller and the bail arm are Since they move as a unit, there is a problem that the bail arm is easily turned over.

[Problems to be Solved by the Invention] The present invention is intended to solve the above problems, in which the guide roller is set at an appropriate angle with respect to the guide direction of the fishing line which changes according to the winding diameter of the spool. It is an object of the present invention to provide an angle adjusting mechanism for a fishing line guide roller in a spinin reel that can be adjusted quickly and easily and, after the adjustment, ensures that the guide roller is held at the adjusted angle.

[Means for Solving the Problems] That is, the present invention provides a shaft pin positioned at the base and end of a substantially U-shaped portion formed at the tip of the bail arm lever that supports one end of the bail arm. In the fishing line guide roller of the supported spinning reel, the base end of the shaft pin with respect to the base of the bail arm lever is crossed at a substantially right angle with the fishing line wound around the spool in a direction in which the fishing line is guided by the guide roller. The shaft pin is swingably supported, and the tip end of the shaft pin passes through an elongated hole provided in the swing direction of the shaft pin with respect to the end part of the bail arm lever, and at the end part of the bail arm lever. The eccentric cam surface of the rotatably arranged adjustment cam is elastically contacted by a spring.

[Operation] Since the present invention is configured as described above, the end portion of the bail arm lever is elastically contacted by the spring with the eccentric cam surface of the adjusting cam by rotating the provided adjusting cam. The tip of the shaft pin is moved and adjusted along the elongated hole formed at the end portion against the elastic force of the spring, and the base end of the shaft pin has a fishing line wound around a spool on a guide roller. Since it is pivotally supported so as to be swingable in a direction intersecting at a right angle and guided, it is swung together with the guide roller about the shaft support portion and held at an arbitrary position.

Therefore, when fishing is performed centering on the outside of the intermediate winding diameter illustrated in the above-mentioned section of the prior art, the shaft pin is swung in the clockwise direction in FIG. When fishing is performed centering on the inside of the diameter r, the guide angle of the guide roller and the fishing line guided by the guide roller to the spool can be arbitrarily adjusted by swinging the shaft pin counterclockwise.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIGS. 1 to 5, the tip end of the bail arm lever 1 according to the present invention is the same as the conventional one. A drum-shaped guide roller 4 is formed in a substantially U-shaped portion, and between the base portion 1a and the end portion 1b, a guide groove 4 is provided around a cylindrical outer peripheral surface via a bush 8 so as to be rotatable.

Insert the through hole 5a of the roller receiver 5 to which the base end of the shaft pin 7 is fixed so that the shaft pin 7 can be swung in the direction intersecting with the shaft pin 7, and both ends thereof are coaxial with the mounting hole 2 of the base 1a. It is supported by the recessed hole 9 and the screw hole 10 provided so as to face each other.

Further, the long hole 24 of the end portion 1b of the bail arm lever 1 is provided so as to coincide with the swinging direction of the shaft pin 7, and the tip of the shaft pin 7 is penetrated so that it can be guided in the swinging direction. .

An adjusting cam 14 is rotatably fitted in the recessed hole 13 of the end 1b.

The inner end of the adjusting cam 14 is provided with a protrusion 14a having a cam surface 15 which is eccentric with respect to the axis C of the adjusting cam 14, and the tip 7a of the shaft pin is attached to the spring 17 on the cam surface 15. I am making contact with each other.

That is, the cam surface 15 is provided so that the radius gradually increases from the lower portion 15a having the smallest radius from the axis C of the adjusting cam 14 toward the higher portion 15b, and the cam surface 15 is rotated by the rotation of the adjusting cam 14. 15 moves the tip 7a of the shaft pin 7 along the elongated hole 24 against the resilience of the spring 17, so that the shaft pin 7 is screwed into the screw shaft 11
It is formed so that it can swing around.

Further, the spring 17 is installed in a lateral hole 20 provided in the end portion 1b and is supported by a cover 19.

Here, the adjustment cam 14 has a recessed hole 13 formed in the end 1b.

As shown in the solid line in FIG. 2, the guide roller 4 is moved in the direction indicated by the arrow a in FIG. 1 when the fishing line is wound in the range of R to r. The adjustment cam 14 is rotated counterclockwise in FIG. 4 so as to maintain the inclination, and the tip 7a of the shaft pin 7 is moved to the lower portion 15 of the cam surface 15.
By moving to a, the fishing line wound on the spool 12 has a counterclockwise twist up to about half on the winding diameter r side in FIG. 1, and from about half on the winding diameter R side. Since each is twisted in the clockwise direction, twisting in both directions can be canceled each time the fishing line is thrown.

Further, in FIG. 1, when the fishing line is wound on the spool 12 only up to the fishing line winding diameter r and fishing is performed within the fishing line winding diameter r to r ₁ , as shown by the chain double-dashed line in FIG.

The fishing line wound around the spool 12 has a counterclockwise twist up to about half on the winding diameter r ₁ side in FIG. 1, and a clockwise twist up to about half on the winding diameter r side. Therefore, the twist can be offset in the same manner as described above.

[Advantages of the Invention] Since the angle adjusting mechanism of the fishing line guide roller in the spinning reel according to the present invention is configured as described above, it depends on the amount of fishing line wound on the spool and the amount of fishing line thrown at the fishing spot. The angle of the guide roller for guiding different fishing line winding diameters can be easily adjusted by rotating the adjusting cam forward and backward.

Therefore, since the guide roller guides at a right angle and the inside and outside of the fishing line to be wound can be adjusted in different twisting direction winding amounts simply by rotating the adjusting cam, the twisting of the fishing line in different twisting directions can be adjusted. Since they can be offset each time they are thrown without accumulating, it is possible to reliably prevent the thread from being caught on the rod guide or the like when the ball is thrown, the thread being entangled, or the thread being broken.
