Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a clutch mechanism for transmitting an electric drive to a winding spool of a road thread in a drive mechanism of a fishing reel.

[Conventional technology]

In an electric reel for fishing, the rotation of a motor is transmitted to a spool via a plurality of reduction gears. Further, since the spool needs to rotate freely when the road yarn is delivered, the final gear of the reduction gear and the spool are connected by a clutch. However, in a reel that is both electric and manual, the motor is forcibly rotated in the reverse direction unless some mechanism disconnects the electric drive side during manual driving, which is not preferable in structure.

Therefore, the applicant has adopted the technical means of Japanese Patent Application No. 61-61632 (conventional example 1) and Japanese Patent Application No. 62-115967 (conventional example 2) in order to solve the above inconvenience.

[Problems to be solved by the device]

Among the above-mentioned conventional techniques, in Conventional Example 1, the connection with the electric drive side is performed by the roller clutch, and the connection cannot be completely disconnected. Further, in Conventional Example 2, since a ball urged by a spring is used for the connecting portion and the ball is engaged by this, if the extension force of the spring is weak, the ball cannot be sufficiently engaged.
There was a problem that this part would idle when driven electrically.

SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and provides a clutch mechanism for a fishing reel that transmits electric drive to the rotation of the spool with a simple structure and does not transmit manual drive to the motor side. To aim.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a fishing reel in which the rotation of a motor is transmitted to a spool through a plurality of reduction gears, the outer periphery of which is the final gear of the reduction gear, and the inner periphery of which is gentle in one direction. A main gear having a plurality of cutouts having a slope, a convex portion fitted to the inner circumference on one side, and a clutch plate provided with a lining on the other side surface capable of press-contacting the spool, and the main gear. It is composed of a ratchet gear which is connected to the convex part of this clutch plate with a gear sandwiched and has a ratchet part on the other side, and the convex part of the clutch plate is externally attached by a spring in a shape corresponding to the cutout. A means of pivotally attaching a locking piece that is biased toward one side and that engages with the notch only when the main gear is driven in the forward direction is used.

[Action]

The outer periphery of the main gear finally acts to reduce the speed of driving the motor, and the engagement of the notch provided on the inner periphery with the locking piece transmits the rotational torque in the forward direction to the clutch plate. Further, the rotation of the motor is changed to the rotation of the spool by pressing the lining of the clutch plate against the side surface of the spool. On the other hand, if the clutch plate is rotated by the operation of the manual handle when the motor drive is stopped, the locking piece slides in and out along the gentle slope while moving outwards and outwards, resulting in a notch in the main gear. Does not engage and does not rotate the main gear in the opposite direction.
That is, the one-way clutch function is performed by the configuration of the notch and the locking piece.

〔Example〕

An embodiment of the present invention will be described in more detail below with reference to the drawings. FIG. 1 is a sectional view showing the whole of the mechanism, in which 1 is a motor for electric drive and 2 is directly connected to a shaft of the motor 1. A driving gear, 3 is a plurality of reduction gears, and 4 is a main gear in which a final gear of the reduction gears is provided on the outer periphery. Reference numeral 5 is a clutch plate, and in order to transmit the rotational torque in the forward direction of the main gear 4 to the spool 6, the lining 7 can be pressed against the side surface of the spool 6 by operating a drag or a control lever. Reference numeral 8 is a ratchet gear which is connected to the convex portion 14 on one side of the clutch plate 5 and rotatably sandwiches the main gear 4 between the two, and a ratchet portion 9 is formed on the other side surface, By enabling engagement / disengagement with the ratchet gear 8 in relation to a claw (not shown) provided on the reel body side, spool spooling only (at the time of release) and delivery of line yarn (at the time of engagement) ) Is intended to be switched for both.

2 and 3 are a front view and a longitudinal sectional view showing main parts of the main gear 4, the clutch plate 5, and the ratchet gear 8, and 10 is a final gear provided on the outer periphery of the main gear 4,
A plurality of notches 11 are provided on the inner circumference 12 of the main gear 4, and each notch has a gentle slope 13 in one direction. Reference numeral 14 denotes a convex portion formed on one side of the clutch plate 5, which is inserted into the inner circumference 12 of the main gear 4 and connected to the ratchet gear 8 by a bolt 19. 15 is convex 14
Is a locking piece pivotally attached to a part of which is shaped, and has an outer shape corresponding to the shape of the notch 11 of the inner circumference 12 of the main gear, and supports the rotating shaft 16 protruding at one end on the clutch plate 5. In addition to being rotatable by a fixed amount, the other end side is biased outward by a spring 17. Further, reference numeral 18 denotes a fixed shaft, which supports a rotary sleeve 22 which is fitted over substantially the entire length of the fixed shaft.
In addition to being directly connected to the main gear 4 and ratchet 8
It is the center of rotation, and 20 is an oilless metal, 21 is a lid of the inner circumference 12 of the main gear, and it is a locking piece even when disassembled.
It is welded to the main gear 4 at the time of assembly so that 15 etc. will not fall off.

Next, the operation of the clutch mechanism of the present invention configured as described above will be described. First, when winding the road yarn, the pawl of the ratchet portion 9 is released and then the motor 1 is driven (the motor 1 is a unidirectional drive). (Not rotating in the opposite direction), the main gear 4 rotates in the forward direction indicated by the arrow in FIG. 2 via the reduction gear 3 and, as a result, the lock 17 is biased outward by the spring 17. Piece 15 and cutout
11 engages to rotate the locking piece 15 in the same direction, so that the clutch plate 5 also rotates in the same direction as the locking piece 15 rotates,
The rotational torque of the clutch plate 5 is transmitted to the spool 6 according to the degree to which the lining 7 is pressed against the spool 6.

On the other hand, in the case of manual drive, when the handle 23 is operated in the winding direction of the spool 6, the master gear 24 of the handle shaft 24
The rotary sleeve 22 rotates via the. As a result, the clutch plate 5 directly connected to the rotary sleeve precedes the main gear 4 and rotates in the arrow direction.
Since the sliding rotation is performed while the spring 17 is pressed while sliding on the surface of the gradient 13, the rotation torque of the clutch plate 5 is transmitted to the spool 6 without the main gear 4 rotating in the same direction. That is, when the rotation of the main gear 4 precedes by the electric drive, this rotational torque is transmitted to the spool 6 through the clutch plate 5, and when the rotation of the clutch plate 5 precedes by the manual drive, the rotation thereof is performed. The torque is not transmitted to the main gear 4.

The locking piece 15 can perform the above-mentioned function only by providing it at one place, but in order to prevent inconveniences such as eccentric rotation and to apply a uniform load, the locking piece 15 can be provided at two places or evenly in the symmetrical direction. It is also free to provide three places in the.

Further, at the time of delivering the yarn, the spool 6 can freely rotate in the opposite direction only by friction with the lining 7 by locking the ratchet portion 9 with the pawl and fixing the clutch plate 5. In this case, the main gear 4 and the master gear 24 never rotate.

[Effect of device]

The clutch mechanism of the present invention includes a main gear having a plurality of notches on the inner circumference, which have a gentle gradient in one direction,
With the locking piece of the clutch plate having the convex portion fitted to the inner circumference of the main gear, the locking piece is configured to engage with the notch only when the main gear is driven in the forward direction, Compared to the conventional clutch mechanism of this type, the function of the one-way clutch can be achieved with a remarkably simple structure, and the shape of the notch and the locking piece ensures engagement and disengagement of both, and further The driving rotation torque can also be transmitted without loss. Therefore, it is possible to provide a fishing reel capable of accurately exhibiting the performance of the motor.

Furthermore, the spring for urging the locking piece outward does not require a strong extension force, but rather can exert its function sufficiently with a weak force, so the life of this spring is long, and therefore disassembly / repair is easy. The clutch mechanism of the fishing reel is highly reliable and unnecessary.
