Description

[Detailed description of the invention] The present invention relates to a clutch release mechanism for a double-shaft reel, which is provided to wind or release fishing line by rotating a spool installed between left and right side frames in the forward or reverse direction. Utsukko 1977 proposed by the applicant
This invention relates to an improvement of the clutch release mechanism disclosed in Publication No. 14608. In the case of the above-mentioned reel, the handle shaft and the spool shaft are interlocked with each other so that they can be released, and when casting, the above-mentioned clutch is turned off (released) to free the spool, or when the fishing line is wound. Use clutch when removing
By turning ON and connecting the spool shaft and handle shaft, the spool can be rotated in the normal direction by operating the handle, and the clutch is turned ON and OFF.
The switching operation is performed by a clutch release mechanism equipped with a lever.

However, the conventional clutch release mechanism described above is
The clutch was turned OFF by pressing and rotating the push button directly with a finger, and the push button was provided on the top or side of the side frame of the reel body, so the clutch could only be turned on and off.
The OFF switch is now operated with the fingers of the other hand, which is different from the one holding the fishing rod, so during the casting stage, the fingers of the hand holding the fishing rod must be used to prevent the fishing line from being let out. While holding the spool with the spool and operating the thumb, turn the clutch on with one hand and the other.
Since the OFF switching operation had to be performed, it had to be operated with both hands, which resulted in poor operability.

Japanese Patent Publication No. 56-5129 is known as a device that can overcome the drawbacks of the conventional technology. Because it rotates around a shaft that is supported by both support plates, it is difficult to press and rotate using only the operating fingers (mainly using the thumb), and as it involves rotation of the wrist joint, repeated use can cause fatigue. The force transmission efficiency from the release key deteriorates due to the tactile sensation and the sliding movement of the release arm, making it necessary to increase the force with which the release key is pressed.

The present invention solves the above-mentioned drawbacks of the conventional mechanism, reduces the pressing force of the push lever for releasing the clutch during casting, reduces the feeling of fatigue in the hands, and also aims to reduce the failure rate by simplifying the mechanism. This is the purpose.

The present invention will be described in detail below based on an embodiment shown in the drawings. First, as shown in FIGS.
In the reel body 1, which has a frame formed by a plurality of support rods 3 supporting the rods 2b at appropriate intervals, the spool 4 is mounted between the side plates 2a, 2b or the side frames 2, 2' fixed to the spool shaft. A handle shaft 6 with a handle 6a rotatably supported on a pivot 24 protruding from one side plate 2b, and the spool shaft 5 are mounted in the side frame 2'. The clutch 7 is interlocked with the clutch 7 so as to be operatively releasable via a drag mechanism (not shown), and a rod holder 8 is fixed to the side frames 2, 2' below the spool 4. The structure is the same as that of a known reel of this type, so a detailed explanation will be omitted.

Thus, as shown in FIGS. 1 to 3, the clutch release mechanism of the present invention has long holes 2c and 2d facing each other in the rear sides of the side plates 2a and 2b of the left and right side frames 2 and 2' of the reel body 1, respectively. A spool is formed to extend through the long holes 2c and 2d in a substantially concentric arc shape, and both ends of the lever shaft 10 having the push lever 9 passed therethrough are slidably inserted into the long holes 2c and 2d. A lever 11 is pivotally supported to be slidable within a length range, and is rotatable by a pin 12 in the vicinity of a bent portion of a lever 11 which is bent in a substantially L-shape from the front on the side plate 2b and is close to the push lever 9. One end 11a of the lever 11 is brought into contact with the outer surface of the lock lever 13 of the clutch 7, the other end 11b is brought into contact with the lever shaft 10, and the pin 12 is fitted with a spring 14. By hooking one end to a spring hook 15 protruding from the side plate 2b and hooking the other end to the lever 11, the lever 11 is resiliently biased clockwise in FIGS. 2 and 3. As a result, the lever shaft 10 and the push lever 9 are held in the non-operating position shown in FIG. It is configured to be

Here, the attachment position of the push lever 9 is determined when the reel is attached to the rod 18 with the rod holder 8 and the finger (for example, thumb) of the hand holding the rod 18 is used to perform a thumb operation on the spool 4. At the same time, you can operate push lever 9 and turn clutch 7 on.
It is arranged in the rear part of the reel main body 1 at a position where the OFF switching operation is possible.

According to the illustrated example, the clutch 7 is connected to a slide plate 19 for moving a pinion (not shown) in the axial direction to operatively connect and detach the spool shaft 5 and the handle shaft 6 by reciprocating rotation. Clutch cam 20 that slides the slide plate 19
And, one end is attached to the side plate 2b with shaft pins 21 and 22, respectively.
Tight lever 13 and cam lever 1 pivoted at
6, etc., and a pin 23 is inserted into a long hole 20a provided at one end of the clutch cam 20 to be pivotally connected to the other ends of the tightening lever 13 and the cam lever 16,
Normally, the clutch 7 is held in the ON state by being held in the state shown in FIG. 2 by the spring 17, and in this state, the push lever 9 is moved to the second position.
In the figure, slide the lever shaft 10 downward.
is slid downward along the long arc-shaped holes 2c and 2d that are substantially concentric with the spool, and the other end 11b of the lever 11 is pressed, thereby causing the lever 11 to apply a spring force using the pin 12 as a fulcrum. By being rotated counterclockwise against the resistance, the tightening lever 13 is pressed by its one end 11a, and the tightening lever 13 is rotated clockwise using the shaft pin 21 as a fulcrum, thereby pivoting the cam lever 16. Spring 1 is rotated counterclockwise using pin 22 as a fulcrum.
As a result, the clutch cam 20 rotates clockwise as shown in FIG. 3, and its convex cam surfaces 20b cause the slide plate 19 to move in the axial direction. The connection between the spool shaft 5 and the handle shaft 6 is released. In other words, the clutch is switched OFF and the spool 4
is formed to rotate freely.

Here, a return spring (not shown) is interposed on the slide plate 19, and the clutch is pressed here.
To turn the handle ON, rotate the handle 5a clockwise to rotate the handle shaft 6.
As shown in FIG.
The spring 17 rotates beyond the dead center by one tooth of the zero gear 30a, and the clutch cam 20 also rotates, bringing the clutch into a connected state.

According to the present invention, the clutch 7 is not limited to the illustrated example, but includes a tightening lever 13 that is pressed by the lever 11 and a clutch cam 20, and the tightening lever 13 is pressed by the lever 11 as described above. Clutch 7 by being operated
The structure is arbitrary as long as the clutch 7 is released and the spring 17 returns when the pressing force of the tightening lever 13 is released and the clutch 7 is turned on.

As explained above, the clutch release mechanism according to the present invention is constructed and operated, so when using a double-shaft reel, the push lever 9 is slid in an arc concentric with the spool using the finger of the hand holding the rod. Kick lever 1 that is completed and rotates around the shaft pin 21
3 is rotated by the lever 11 around the pin 12, and the pushing force is transmitted with good transmission efficiency, and the pushing torque of the push lever 9 can release the clutch 7 with a light touch. By being able to perform the summing operation of the spool 4 and the clutch switching operation, especially the clutch release operation, with the fingers of the hand holding the reel 18, simultaneously and with one hand, the reel casting operation can be made easier. It has a simple structure, a small number of parts, and is highly reliable with few failures, which has the effect of significantly improving the operability of this type of reel compared to conventional products.

In addition, since the push lever 9 is of a sliding type, its length can be made shorter than that of a rotating type, and it does not protrude outward from the reel body 1 for a long time. There is no possibility of damage due to interference with objects or malfunction of the clutch 7 when winding the fishing line, etc., and the number of components is the same as or less than that of the conventional mechanism, and the structure is simple. It can be manufactured at low cost.
