Description

Description: TECHNICAL FIELD The present invention relates to a clutch for an electric reel.

(Prior Art) In an electric reel, a clutch is used as a means for bringing a spool into a free state or a connection state with respect to a rotation driving means (motor) of the spool. A clutch member provided in the electric reel body is movable between a first position and a second position, and when the clutch member is at the first position, the spool is free from driving means. When the clutch member is at the second position, the spool can be connected to the driving means so that the spool can be rotated by the driving means. Conventionally, the user manually switches the position of the clutch member by switching a switching knob provided on the electric reel body. Recently, an electric reel equipped with a microcomputer has appeared, and by controlling the rotation of the spool, it is possible to provide functions such as automatic shelving and stopping a boatslide. For this reason, it is necessary to automatically operate the clutch member (moving between the first position and the second position), so that a clutch for an electric reel in which the clutch member is operated by a solenoid is also used. It has become.

(Problems to be Solved by the Invention) However, the above-described solenoid type electric reel clutch has the following problems.

When one solenoid is used as the operating means of the clutch member, the clutch member can be operated only in one direction from the first position to the second position or from the second position to the first position. When the function of the electric reel is limited, the automatic operation of the clutch member may be one-way. It is required to automatically move in both directions from the first position to the second position and from the second position to the first position. For this reason, a method of incorporating and operating two solenoids has been proposed and realized. However, there is also an economical problem that the electric reel becomes larger and heavier to incorporate two solenoids, thereby increasing the manufacturing cost.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a small, lightweight, and inexpensive electric reel clutch capable of operating a clutch member in both directions.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, a clutch member movable between a first position and a second position is provided, and when the clutch member is at the first position, the spool is free with respect to the driving means of the spool. State, and when the spool is in the second position, the spool is connected to the drive means. In the clutch for an electric reel, the clutch member includes one clutch motor capable of rotating forward and reverse, and It is connected via a transmission mechanism that can prevent the movement of the clutch member when stopped, moves to the first position when the clutch motor rotates in one direction, and moves when the clutch motor rotates in the other direction. Has solved the problem as a configuration for moving to the second position.

(Action) The action will be described.

Since the movement of the clutch member is performed by a single clutch motor that can rotate forward and reverse, the solenoid is operated by two
Compared with the case of using the electric reel, the space required for assembling the electric reel can be reduced, and the weight can be reduced.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front sectional view of a main part of an internal mechanism of the electric reel of the present embodiment, and FIG. 2 is a right side view of a main part of a clutch part.

 First, the configuration will be described.

Reference numeral 10 denotes a spool, which is rotatable by receiving a rotational force of a driving motor 12 as driving means. A gear 16 is fixed to the right end of the output shaft 14 of the drive motor 12, and meshes with planetary gears 20 arranged on the left side of a disk 18 arranged in the space inside the spool 10.

22 is a shaft, about half of the left side protrudes into the space inside the spool 10, and the right end part is a casing of the reel body, etc.
It is pivotally supported by a suitable member 24. A disk portion 26 is formed at the left end of the shaft 22, and planetary gears 28... Disposed on the left side surface of the disk portion 26 are fixed to a gear 30 fixed to the right side surface of the disk 18. Is engaged. Therefore, the shaft 22 is rotatably supported inside the reel body. Further, the planetary gears 28 are gear parts engraved on the inner wall surface of the spool 10.
Also meshed with 32. If the shaft 22 is rotatable without any restriction from other members, the rotational force of the drive motor 12 rotates the disk 18 from the output shaft 14 via the gear 16 and the planetary gears 20. Further, the rotational force of the disk 18 is transmitted to the planet gears 28 through the gear 30. At this time, if the shaft 22 is freely rotatable as described above, the disk portion 26 rotates together with the shaft 22, and the planetary gears 28 revolve and rotate, so that the gear portion of the spool 10 of the planetary gears 28. The rotation with respect to 32 is canceled and the spool 10 is
It is configured to be in a free state without receiving the rotational force from 12. On the other hand, in a state where the shaft 22 is non-rotatably interfered by other members, the rotational force of the drive motor 12 is transmitted from the output shaft 14 to the disc via the gear 16 and the planetary gears 20.
Rotate 18. Further, the rotational force of the disk 18 is transmitted to the planet gears 28 through the gear 30. However, if the shaft 22 cannot rotate, the planetary gears 28... Rotate only at the fixed position, so that the planetary gears 28. The state in which the spool 10 rotates by receiving the rotation force of the drive motor 12 is referred to as a connected state.

Next, a clutch mechanism for bringing the spool 10 into the free state or the connected state will be described.

Reference numeral 34 denotes a fixed fitting body, which is formed in an oval side sectional shape (not limited to an oval shape if it is non-circular), and has a shaft
Fixed in place on 22.

Reference numeral 36 denotes a clutch member, in which a fitting portion 38 formed into a cylindrical shape on the left side and a gear portion 40 formed on the right side are integrated. The left end face of the fitting portion 38 is opened, and the inner wall surface is formed in a shape following the oval outer shape of the fixed fitting body 34 so that it can be fitted to the fixed fitting body 34. The gear unit 40 is always engaged with a gear 42 connected to a manual handle (not shown). The gear 42 cannot be rotated by an appropriate lock mechanism (eg, ratchet type lock mechanism) except for a special case such as when a manual handle (not shown) is used. The clutch member 36 is fitted on the shaft 22 so as to be movable in the left-right direction, and is constantly pushed leftward by a biasing means such as a spring 44. As shown in FIG. 1, if the clutch member 36 has moved rightward (it is said to be in the first position) and the fitting portion 38 and the fixed fitting body 34 are not fitted, the shaft 22 Is rotatable and spool
10 is free. On the other hand, the clutch member 36 has an arrow A
If the fitting portion 38 is moved in the direction (in the second position) and the fitting portion 38 is fitted with the fixed fitting body 34, the gear portion 40 meshes with the non-rotatable gear 42 so that the shaft 22 rotates. The connection state is disabled, and the spool 10 is rotated by receiving the rotational force of the drive motor 12.

Reference numeral 46 denotes a moving piece, which is formed in a semi-ring shape as clearly shown in FIG. There are extending portions 50 and 52 extending in the radial direction, and ring portions 54 and 56 are formed at both ends of the extending portions 50 and 52. Rings 54, 56
Are loosely fitted to shafts 60 and 62 erected from the right side of a member 58 fixed inside the reel body. Therefore,
The moving piece 46 can be moved left and right by being guided by the shafts 60 and 62.

Reference numeral 64 denotes a driving piece, and one end of an arc-shaped portion 66 having a flat C-ring shape is mounted on a shaft 68 provided upright on the member 58. The other end of the arc-shaped portion 66 is bent to project rightward as a protruding portion 70 as clearly shown in FIG.
In the figure, it is bent so as to protrude toward the near side with respect to the paper surface). The position of the driving piece 64 in the left-right direction is unchanged,
The rotation about the shaft 68 enables the protrusion 70 to push the extending portion 50 of the moving piece 46 rightward by the rotation of the driving piece 64. The state shown in FIGS. 1 and 2 is a state in which the movable piece 46 is pushed rightward by the projection 70, and as a result, the clutch member 36 is pushed to the first position. Therefore, when the driving piece 64 is rotated in the direction of arrow B in FIG. 2, the contact between the extension 50 and the protruding part 70 is released, and the moving piece 46 becomes movable to the left. The moved clutch member 36 and the moving piece 46 move to the left,
Moves to the second position.

In the present invention, the rotation of the driving piece 64 is performed by one clutch motor 72. The clutch motor 72 is fixed to the member 24, and its rotation is reduced through an appropriate reduction mechanism 74. The output shaft (not shown) of the reduction mechanism 74
76 is installed. The left end of the crank 76 is the drive piece
When the crank 76 is rotated by the rotation of the clutch motor 72, the drive piece 64 is rotated about the shaft 68 when the crank 76 is rotated by the rotation of the clutch motor 72. Can be moved. The rotation direction of the driving piece 64 may be controlled by the direction of the current flowing to the DC clutch motor 72.

The reduction mechanism 74, the crank 76, the moving piece 46, and the driving piece 64
Thus, the clutch member 36 can be moved between the first position and the second position by the rotational force of the clutch motor 72.

Reference numerals 82 and 84 denote stoppers, which are erected on the right side of the member 58 and regulate the amount of rotation of the driving piece 64. When the clutch motor 72 is stopped, the speed reduction mechanism 74
The structure is such that the rotation of the output shaft to which is mounted can be prevented.

In the electric reel configured as described above, the clutch motor 72 is operated by a switch operation or a command from the microcomputer, the clutch member 36 is moved to the first position or the second position depending on the rotation direction, and the spool 10 is set in the free state or The connection state can be set.

Although various preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments.For example, a manual knob for setting the spool to a free state or a connected state is provided. It goes without saying that more modifications can be made without departing from the spirit of the invention.

(Effect of the Invention) When the electric reel clutch according to the present invention is used, bidirectional operation of the clutch member is enabled by one clutch motor. Therefore, the required space is smaller than in the case where two solenoids are incorporated as in the related art, so that the size and weight of the electric reel can be reduced. Further, in addition to downsizing and weight reduction, one inexpensive motor can be used as compared with two solenoids, so that the production cost can be reduced.
