In the electric reel, as a clutch function for transmitting the rotational driving force of the electric motor to the spool around which the fishing thread is wound, Patent Document 1 provides a plurality of pins on a disk to which the electric motor is connected, and the disk to which the spool is connected is provided with a plurality of pins. It has been shown that a clutch mechanism is constructed by forming a hole and moving one disk to engage and disengage the pin and the hole. However, it is difficult to insert the pin of the disk rotating at high speed into the hole of the other disk, and even if it is inserted, the impact is large, so that there is a problem that the pin is damaged.

Further, in Patent Document 2, the electric motor is attached so as to move up and down, the electric motor is tilted by sliding the switch, the clutch is disengaged when the rotation drive shaft is separated from the flange of the spool, and the switch is returned. The clutch mechanism is shown in which the clutch is engaged by making the electric motor horizontal and bringing the rotary drive shaft into contact with the flange of the spool, and the spool is rotated by the electric motor to wind up the fishing thread. However, since the electric motor, which is a precision electric component, is rotated up and down by a slide switch to operate the clutch, there is a problem that it is liable to break down.

Further, in Patent Documents 3 and 4, a clutch mechanism is provided in which the spool is attached so as to move up and down by a cam, and the cam is rotated to switch between the connected state and the disconnected state of the spool and the rotary drive shaft of the electric motor. It is shown. However, since the cam mechanism for moving the spool up and down is provided, the configuration becomes complicated and may cause a failure. Moreover, it is necessary to have a configuration in which the spool is held at either the upper or lower position and a configuration in which the spool is held when the cam is switched, which causes a problem that the size of the electric reel is increased and the cost is inevitably high.

The problem to be solved by the present invention is to provide an auto-clutch mechanism for a small electric reel having a simple structure and a clutch mechanism capable of automatically switching the connection between the rotary drive shaft of the electric motor and the spool. be.

Therefore, the auto-clutch mechanism of the small electric reel according to the present invention is an electric reel in which the spool is rotationally driven by an electric motor, and is centered on the electric motor arranged in the main body and a fulcrum provided in the main body.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show an embodiment for a fishing rod suitable for small fish such as smelt as an auto-clutch mechanism for a small electric reel according to the present invention. The grip portion 1 made of wood or plastic is formed in a columnar shape having a thickness that is easy for the user to grip. A tip 2 is attached to the tip of the grip portion 1. Further, on the lower side of the grip portion 1, a motor accommodating portion 1a for accommodating the electric motor 3 is formed. Here, in the illustrated embodiment, the grip portion 1 is exemplified as the main body portion. However, the main body portion may be configured as a separate body from the grip portion 1 and mounted on the grip portion 1. In this embodiment, the main body portion will be described as the grip portion 1.

The electric motor 3 housed in the grip portion 1 is arranged so that the rotation drive shaft 3a is orthogonal to the longitudinal direction of the grip portion 1 as the main body portion. The outer circumference of one flange 4a of the spool 4 is in contact with the rotary drive shaft 3a of the electric motor 3, and is rotationally driven by the electric motor 3. In the illustrated embodiment, the rotary drive shaft 3a is a rotary shaft provided on the electric motor 3 itself. The rotary drive shaft 3a may be provided with a reduction mechanism by a gear or the like between the rotary shaft of the electric motor 3 and the rotary drive shaft 3a that comes into contact with the spool 4 in accordance with the rotation speed of the spool 4. ..

The spool 4 is formed in a bobbin shape so as to wind a fishing line 9 described later, and flanges 4a are formed on both left and right sides. A through hole is formed in the direction orthogonal to the flange 4a. An engaging member 3b made of a non-slip member for preventing slipping, such as rubber, is fitted to the rotary drive shaft 3a of the electric motor 3 that comes into contact with the outer periphery of the flange 4a. When the engaging member 3b comes into contact with the rotation drive shaft 3a, the rotation of the electric motor 3 is transmitted to the spool 4. The spool 4 is rotatably arranged on a shaft 5a provided on the swing arm 5.

The swing arm 5 is configured to swing around a fulcrum portion 6 provided on the side surface of the grip portion 1. The flat portion in the vicinity of the spool 4 is used as the pressing portion 5b. On the other hand, a swing magnet 7 is fixed to the rear end of the swing arm 5. As the oscillating magnet 7, for example, a neodymium permanent magnet formed in a button shape is suitable. A magnetic body 8 is arranged in the grip portion 1 at a position corresponding to the rocking magnet 7. As the magnetic body 8, in addition to fixing an iron piece made of iron or the like, iron screws or wood screws are suitable.

A substantially dish-shaped cover 10 is integrally formed on the swing arm 5, so that one flange 4a of the spool 4 is covered inside the cover 10 and the other flange 4a is exposed from the cover 10. It is arranged. Then, a U-shaped protrusion 10a is formed at a position corresponding to the rotation drive shaft 3a of the electric motor 3 of the cover 10, and a U-shaped protrusion 10a is joined inside the protrusion 10a as shown in FIGS. 4 to 6. The portions 10b are integrally projected. The joint portion 10b is adapted to be brought into contact with and separated from the engaging member 3b fitted to the rotary drive shaft 3a of the electric motor 3 by the swing of the swing arm 5, and is joined to the engaging member 3b by frictional force. is doing. The joint portion 10b is not limited to the semi-cylindrical shape as shown in the drawing, and may have another shape such as a rectangular shape, a substantially triangular shape, or a trapezoidal shape as long as the top portion is joined to the engaging member 3b. The clutch portion is formed by the engaging member 3b of the rotary drive shaft 3a and the joint portion 10b protruding from the cover 10. As will be described later, when the rotary drive shaft 3a is rotationally driven in a state where the joint portion 10b is joined to the engaging member 3b, the clutch portion is spooled by separating the joint portion 10b by the rotational drive of the rotary drive shaft 3a. The clutch operation for rotationally driving the spool 4 by engaging with one of the flanges 4a of 4 is automatically performed.

On the other hand, the tip 2 detachably attached to the tip of the grip portion 1 which is the main body is, for example, a tip generally commercially available as a fishing rod for smelt, and although detailed description is omitted, it is wound around a spool 4. A fishing hook 11 and a weight 12 are attached to the tip end side of the fishing line 9. Further, the fishing line 9 is guided by a fishing line guide ring 13 provided on the tip end side of the grip portion 1.

As shown by the dotted lines in FIGS. 1 and 2, the battery 14 is housed behind the grip portion 1. The battery 14 may be stored in an external battery box. Then, the electric motor 3 is rotationally driven using the battery 14 as a power source. The battery 14 and the electric motor 3 are connected by an electric wire (not shown), and the drive and stop of the electric motor 3 are operated by a switch 15 arranged on the side of the grip portion 1.

Next, the operation of the clutch portion of the above-mentioned electric fishing reel will be described. FIG. 4 shows a state in which the spool 4 can rotate freely. In this state, by pressing the pressing portion 5b of the swing arm 5 below the arrow, the swing arm 5 swings counterclockwise around the fulcrum portion 6. Due to this swing, the rotary drive shaft 3a of the electric motor 3 of the cover 10 is inserted into the U-shaped protrusion 10a, and the engaging member 3b of the rotary drive shaft 3a abuts on the joint portion 10b in the protrusion 10a. .. As a result, the rotary drive shaft 3a of the electric motor 3 is braked by the joint portion 10b. On the other hand, since the flange 4a of the spool 4 is separated from the rotation drive shaft 3a, it can rotate freely. Therefore, the fishing line 9 wound around the spool 4 can be unwound and the hook 11 and the weight 12 can be thrown into the water. can. The length of the fishing line 9 can be adjusted by the hook installed on the spool 4, and when the fishing line 9 is hooked on the hook at the first fishing depth, the clutch is in a free state. However, the fishing hook 11 is designed to stay at that depth.

After that, when the fishing line 9 is unwound to a predetermined length, the switch 15 is pushed to rotate and drive the electric motor 3. Then, as shown in the circle of FIG. 4, the rotation drive shaft 3a rotates clockwise, the joint portion 10b is pushed downward by the frictional force of the engaging member 3b, and the swing arm 5 is centered on the fulcrum portion 6. Swings clockwise. As a result, as shown in FIG. 5, the rotation drive shaft 3a of the electric motor 3 comes into contact with the flange 4a of the spool 4, and the rotation of the spool 4 is prevented. At this time, since the swing magnet 7 fixed to the rear end of the swing arm 5 is attracted to the magnetic body 8, the state in which the rotation of the spool 4 is blocked is maintained.

When winding the fishing line 9, the switch 15 is pushed to rotate and drive the electric motor 3. Then, the rotation of the rotation drive shaft 3a of the electric motor 3 is transmitted to the flange 4a of the spool 4, and the fishing line 9 is wound up. Then, when the fishing line 9 is wound up to an arbitrary length, the switch 15 is released to turn it off, so that the electric motor 3 is stopped and the rotation of the spool 4 is stopped. At this time, since the rotary drive shaft 3a of the electric motor 3 is in contact with the flange 4a of the spool 4, the fishing line 9 is not fed out.

Then, when the fishing line 9 is extended to a predetermined length again, the pressing portion 5b of the swing arm 5 is pressed in the direction indicated by the arrow to return to the free state shown in FIG. As a result, as described above, the rotary drive shaft 3a of the electric motor 3 of the cover 10 is inserted into the U-shaped protrusion 10a, and the engaging member 3b of the rotary drive shaft 3a is the joint portion 10b in the protrusion 10a. The rotary drive shaft 3a of the electric motor 3 is braked by the joint portion 10b. In this state, since the flange 4a of the spool 4 is separated from the rotation drive shaft 3a, it can rotate freely. Therefore, the fishing line 9 wound around the spool 4 is unwound, and the hook 11 and the weight 12 are thrown into the water. Can be done.

7 and 8 show a second embodiment of the electric fishing reel. The same reference numerals as those of the first embodiment shown in FIGS. 1 to 5 indicate the same parts, and detailed description thereof will be omitted. As shown in FIG. 7, the difference from the above-described embodiment is that the outer periphery of at least one flange 4b of the spool 4 is formed in a gear shape, and the joint portion formed in the cover 10 of the swing arm 5 is in the shape of a gear. The engaging member 3b formed in the gear joint 20 and provided on the rotary drive shaft 3a of the electric motor 3 is a drive gear 21. The gear joint 20 as a joint formed on the cover 10 has two teeth, but the number of appropriate teeth is one or three or more depending on the train wheel with the drive gear 21. You can do it.

The operation of the clutch portion in this second embodiment will be described. FIG. 6 shows a state in which the spool 4 can rotate freely. In this state, by pressing the pressing portion 5b of the swing arm 5 in the direction indicated by the arrow, the swing arm 5 swings counterclockwise around the fulcrum portion 6, and the electric motor 3 of the cover 10 is in this state. The rotary drive shaft 3a is inserted into the U-shaped protrusion 10a, and the drive gear 21 of the rotary drive shaft 3a meshes with the gear joint 20. As a result, the rotary drive shaft 3a of the electric motor 3 is braked by the gear joint portion 20. On the other hand, since the flange 4a of the spool 4 is separated from the rotation drive shaft 3a, it can rotate freely. Therefore, the fishing line 9 wound around the spool 4 can be unwound and the hook 11 and the weight 12 can be thrown into the water. can.

After that, when the fishing line 9 is unwound to a predetermined length, the switch 15 is pressed for a short time to rotationally drive the electric motor 3. Then, as shown in the circle of FIG. 6, the drive gear 21 of the rotary drive shaft 3a rotates clockwise and is separated from the train wheel of the gear joint portion 20. At this time, the gear joint 20 is pushed downward, and the swing arm 5 swings clockwise around the fulcrum 6. As a result, as shown in FIG. 7, the rotary drive shaft 3a of the electric motor 3 meshes with the gear-shaped flange 4a of the spool 4, and prevents the spool 4 from rotating. In this state, the swing magnet 7 fixed to the rear end of the swing arm 5 is attracted to the magnetic body 8, so that the rotation of the spool 4 is prevented.

When the fishing line 9 is wound up, the switch 15 is pressed to rotate the electric motor 3. Then, the rotation of the drive gear 21 of the rotary drive shaft 3a of the electric motor 3 is transmitted to the flange 4a of the spool 4, and the fishing line 9 is wound up. Then, when the fishing line 9 is wound up to an arbitrary length, the switch 15 is released to turn it off, so that the electric motor 3 is stopped and the rotation of the spool 4 is stopped. At this time, since the rotary drive shaft 3a of the electric motor 3 is in contact with the gear-shaped flange 4a of the spool 4, the fishing line 9 is not fed out.

Then, when the fishing line 9 is extended to a predetermined length, the pressing portion 5b of the swing arm 5 is pressed in the direction indicated by the arrow to return to the free state shown in FIG. As a result, as described above, the rotary drive shaft 3a of the electric motor 3 of the cover 10 is inserted into the U-shaped protrusion 10a, and the drive gear 21 of the rotary drive shaft 3a is the gear joint 20 in the protrusion 10a. The rotary drive shaft 3a of the electric motor 3 is braked by the gear joint portion 20. In this state, since the flange 4a of the spool 4 is separated from the rotation drive shaft 3a, it can rotate freely. Therefore, the fishing line 9 wound around the spool 4 is unwound, and the hook 11 and the weight 12 are thrown into the water. Can be done.

Although the present invention has been specifically described above based on the examples, it is needless to say that the present invention is not limited to the above examples and can be variously modified without departing from the gist thereof. In the above-described embodiment, the grip portion of the fishing rod for the smelt fishing rod is used as the main body as an example, but various types of fishing rods for fishing rods for small fish may be used, and the small electric reel described above for these various fishing rods may be used. You may install an auto clutch for.
