Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a driving mechanism that enables three types of driving methods of electric driving / manual driving or a combination driving of both in an electric / manual fishing reel. Regarding

[Conventional technology]

BACKGROUND ART Conventionally, in fishing reels, various configurations have been developed in which both electric drive and manual drive are taken into consideration in consideration of a failure of a drive system when only electric drive is used. For example, interposing a multi-plate clutch in the electric drive system and the manual drive system, disconnecting one of the connections with a changeover switch or lever,
A configuration is known in which only the other is connected. However, in this configuration, either electric drive or manual drive can be selected, and when a large fish is caught during electric drive, the drive torque of only the motor cannot wind up the thread, and There was an inconvenience that the road thread had to be pulled back by the work.

Therefore, in order to solve these problems, the applicant has filed a patent application 61-
By adopting the technical means of No. 61632 (conventional example 1) and Japanese Patent Application No. 62-115967 (conventional example 2), three-mode drive is performed in which electric drive is used to perform additional winding to reduce the load on the motor. Method.

Among them, in Conventional Example 1, the rotation of the handle and the drive of the motor are transmitted to the spool by the clutch, and the ratchet mechanism provided on the side surface of the handle prevents the handle from rotating together when the electric power is applied. It was

Further, in the conventional example 2, the drive of the motor is transmitted to the reduction gears of several stages, the sleeve integrated with this is rotated to rotate the spool via the clutch plate, and the rotation of the handle also reduces the speed to the electric side. The structure is such that the gear is driven and the handle is prevented from co-rotating by the ratchet when electrically driven.

[Problems to be solved by the device]

In the above-described conventional technique, in the first conventional example, when an excessive load is applied to the spool, such as when a large fish is caught during electric driving, the handle rotates together with the winding of the road thread, so that the reel is operated. However, there is a problem that the property is significantly reduced.

Further, in the second conventional example, the sleeve integrated with the reduction gear on the electric side is rotated, and the spool is rotated via the clutch plate. Further, the rotation of the handle must be transmitted to the sleeve. Becomes complicated. Furthermore, since the ratchet mechanism for preventing co-rotation of the handle is provided on one side of the handle, there is a problem that not only the structure becomes more complicated but also there is a danger during use. .

The present invention solves the above-mentioned conventional problems, and provides a drive mechanism for a fishing reel in which electric drive / manual operation can be automatically selected with a simple configuration and the ratchet mechanism itself is also incorporated in the drive mechanism. It is what

[Means for solving the problem]

In order to achieve the above object, the present invention transmits the rotation of a motor to a spool through a plurality of reduction gears, and
In an electric / manual combined reel that transmits the rotation of a manual handle to a spool, the rotation of the motor is the final gear of the reduction gear on the outer circumference, and the main gear is provided with an internal toothed ratchet gear on the inner circumference. This ratchet gear has a locking piece that engages only when it is driven forward, and an electric drive mechanism that transmits it through a clutch plate that has a lining that can be pressed into contact with the spool on the opposite surface, and rotation of the handle. , A ratchet gear provided at the tip of a handle shaft to which this handle is fixed, a master gear that internally stores a claw that engages only when the ratchet gear is normally rotated, and a sleeve that is rotated by this master gear,
A means of having a manual drive mechanism for transmitting by the clutch plate directly connected to this sleeve was used.

[Action]

First, in the electric drive, the rotation of the motor is transmitted to the main gear via the plurality of reduction gears. The ratchet gear having an internal tooth shape of the main gear and the locking piece of the clutch plate have a function of transmitting only the driving torque of the forward rotation of the motor to the clutch plate and rotating the clutch plate. As a result, when the lining of the clutch plate is pressed against the spool, the spool can be rotated by electric drive. On the other hand, since the clutch plate is directly connected to the sleeve, the master gear also rotates, but when the master gear rotates in the forward direction ahead of the ratchet gear of the manual mechanism, the rotation is not transmitted to the ratchet gear, Therefore, it has a special effect that the handle also does not rotate.

At the same time, in the manual drive mechanism of the present invention, the ratchet gear at the tip of the handle shaft also rotates due to the rotation of the handle, but the ratchet gear and the claw of the master gear engage only with the forward rotation of the handle to rotate the handle to the subsequent mechanism. The torque is transmitted, and thereby the clutch plate and the spool are sequentially rotated. On the other hand, even if the clutch plate is rotated in advance, the engagement piece and the ratchet gear having an internal tooth shape are not engaged with each other, so that the reverse rotation of the motor is not performed.

In addition, when the rotation of the clutch plate driven manually by the handle is faster than the rotation of the clutch plate driven by the motor, the drive by the handle is preferentially transmitted to the spool, and the additional winding operation is performed. .

〔Example〕

An embodiment of the present invention will be described in more detail below with reference to the drawings. In FIG. 1, reference numeral 1 is a spool around which a yarn is wound, and the spool is driven by transmitting the rotation of a clutch plate 3 through a lining 2. To do. The clutch plate 3 is directly connected to the sleeve 12 fitted to the fixed shaft 11 and is connected to both electric drive and manual drive. The transmission is transmitted to the main gear 6 via the reduction gear 5, and the main gear 6 and the clutch plate 3 can be engaged by the ratchet mechanism 7.

Next, on the manual drive side, the rotation of the handle 8 is releasably transmitted to the master gear 10 located at the tip of the handle shaft 9, and the master gear 10 is rotated by the sleeve gear 13 of the sleeve 12 rotating on the fixed shaft 11. It is meshed with and transmitted to the clutch plate 3 on the sleeve 12.

2 and 3 show the ratchet mechanism 7 on the electric drive side.
3 shows the engagement portion between the clutch plate 3 and the main gear 6 in detail. Here, 14 is an internal tooth-shaped ratchet gear formed on the inner circumference of the main gear 6, and 15 is a convex portion of the clutch plate 3, which is rotatably fitted through the central portion of the main gear 6. Reference numeral 16 denotes a locking piece pivotally supported between the convex portion 15 of the clutch plate and the inner peripheral surface of the main gear 6 so as to be rotatable by a certain amount, and corresponds to the shape of each concave tooth of the internal tooth ratchet gear 14. A rotary shaft 17 having a shape and protruding from one end is pivotally supported on the clutch plate 3, and a spring 18 urges the other side outward. During electric driving, the main gear 6 rotates ahead of the arrow A direction.

Further, FIGS. 4 and 5 show the details of the engagement relationship between the handle shaft 9 on the manually driven side and the master gear 10 which rotates coaxially, and 19 is the handle shaft 9.
Ratchet gear fixed to the tip of the, 20 is the master gear 10
A concave portion 21 formed on the concave portion, a claw 21 fixed to the concave portion 20 by a pin fitting so as to be swingable, and a reference numeral 22 a tip of the claw 21 on a ratchet gear.
It is a leaf spring for urging so as to always come into contact with 19.
During manual driving, the ratchet gear 19 rotates in the direction of arrow C to rotate the master gear 10 in the same direction.

The operation of both drive mechanisms configured as described above will be described. First, in the electric drive, the rotational torque of the motor 4 is transmitted to the main gear 6 via the reduction gear 5 to rotate the main gear in the direction of arrow A. Toothed ratchet gear 14
And the locking piece 16 are engaged with each other, and the locking piece 16 is rotationally driven in the same direction. When the torque is transmitted to the locking piece 16 in this way, the clutch plate 3 rotates in the direction of arrow B in synchronization with the main gear 6, and the spool 1 rotates via the lining 2.

In this case, since the clutch plate 3 and the sleeve 12 are directly connected to each other, the sleeve 12 also rotates, and accordingly, the master gear 10
Also rotates in the direction of arrow D, but in this case, the rotation of the master gear 10 precedes, so the pawl 21 and the ratchet gear 19 do not engage, and therefore the handle 8 does not rotate together.

Next, in the manual drive, when the handle 8 is rotated, the ratchet gear 19 precedes and rotates in the direction of arrow C. In this case, the ratchet gear 19 and the claw 21 engage with each other, and the master gear 10 also moves in the direction of arrow D. Rotate synchronously in the direction. Therefore, the sleeve 1
2, the rotational torque is transmitted to the spool 1 via the clutch plate 3 and the lining 2.

Thus, in this case, the clutch plate 3 rotates in the direction of the arrow B prior to the main gear 6, so that the locking piece
Since the 16 and the ratchet gear 14 having the internal tooth shape are not engaged with each other and rotate by sliding, the rotation is not transmitted to the main gear 6. Thus, there is no need to switch between electric drive and manual drive by using a switch or lever, and the drive is automatically selected.

On the other hand, when a large fish that exceeds the winding capacity of the motor 4 is caught during electric driving, not only can the motor thread not be wound up by electric driving alone, but if the driving is continued, the motor 4 will overdrive. This causes the inconvenience of burning out the coil due to the load. Therefore, in the drive mechanism of the present invention, the handle 8 is dealt with in such a case.
It is possible to rewind the vehicle by rotating it faster than the main gear 6 during electric drive.

That is, when the load is small, the rotation speed is naturally higher when the clutch plate 3 is rotated by the motor 4 than when the clutch plate 3 is rotated by the handle 8. Therefore, it is impossible to expect the spool 8 to be assisted by the handle 8. When the rotation speed of the clutch plate 3 becomes slower due to electric power, the rotation of the handle 8 catches up with the rotation of the clutch plate 3 and the function of assisting the drive of the motor 4 by the handle 8 can be exerted. With this, it becomes possible to perform three modes of driving.

[Effect of device]

According to the drive mechanism of the present invention, the engagement between the master gear and the handle shaft is released by the relationship between the ratchet gear and the pawl during the electric drive, and conversely, during the manual drive, the engagement between the main gear and the clutch plate of the ratchet mechanism is released. Since it is canceled by the relationship, it is possible to reliably select the driving means without separately providing the selecting means.

Further, since the drive mechanism of the present invention does not engage or disengage the multi-plate clutch or the like but engages or disengages the gears, it is possible to perform reliable engagement and disengagement. Even by the means, it is possible to prevent the other mechanism from rotating together.

In addition to this, according to the drive mechanism of the present invention, even when a load exceeding the winding capacity of the motor is applied during electric driving, the additional winding can be performed by operating the handle,
It has been possible to provide a highly reliable electric / manual reel drive mechanism that can reduce the load on the motor and effectively prevent damage to the motor.
