Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is mainly used for spinning reels for fishing, and can be manually or electrically operated at any time without the need to operate a switching lever or the like when winding a road thread. Further, the present invention relates to a bail arm drive device that can be operated simultaneously and manually.

[Conventional technology]

Conventionally, spinning reels are exclusively used for pitching fishing, and there are few that are equipped with an electric mechanism because they need to be small and lightweight for the purpose of use, but as one example, Japanese Patent Publication No. 47-21452. The one disclosed after the issue was known. That is, the driving force from the electric motor is transmitted to the output shaft via the gear transmission mechanism, and the output shaft is provided with the electric side overrunning mechanism to enable the hollow shaft to be driven by the gear, and also the power transmission shaft of the manual handle. By rotating the hollow shaft from the manual-side overrunning mechanism via a gear, the spinner with the bail arm attached is a spinning reel that is driven by the hollow shaft. It is composed of a rotator supported, a gear wheel arranged around the rotator, and a rotor held by a spring and wedged between the rotator and the gear wheel.

[Problems to be solved by the device]

However, the overrunning mechanism in the spinning reel having the above-mentioned structure has to be structurally large in size, so a considerable space must be secured in the radial direction around the motor output shaft and the handle rotation shaft. However, there was a problem that the size and weight of the whole Ikioi reel could not be avoided.

In view of such circumstances, the present invention has an object to provide a small and lightweight spinning reel which has a simple structure and can be manually or electrically selected or used simultaneously.

[Means for Solving the Problems]

In order to solve the above problems, the present invention provides a spinning reel having a bail arm rotatably mounted on a spool shaft that can slide a certain amount, and a sun gear that rotates in only one direction in conjunction with a motor. A plurality of planet gears that are rotatably supported by a spider provided coaxially with the sun gear and that rotate by meshing with the sun gear, and transmit the rotation of the planet gears to the bail arm via an internal gear. And a worm shaft for transmitting the rotation of the manual gear to the spider, and the planetary gear on the spider. It is also provided with a manual mechanism section that rotates the internal gear by the revolution of the gear.

[Action]

In the drive device of the present invention, first, in the electric mechanism section, the sun gear rotates when the motor is driven, and the planetary gears also rotate accordingly.

In this case, since the spider on which the planetary gears are axially supported is in a fixed state by engaging with the manual gear side via the worm shaft, the planetary gears only rotate. As a result, the internal gear meshing with the planetary gear is rotated, and the bail arm is further rotated.

Next, as the operation of the manual mechanism section, when the handle is rotated in the winding direction of the road thread, the manual shaft and the manual gear are integrally rotated, and further the spider is rotated via the worm shaft. .

In this case, since the sun gear is engaged with the electric side and is in a fixed state, each planet gear supported by the spider revolves around the sun gear. As a result, the internal gear that meshes with the planetary gear rotates in conjunction with each other, and the bail arm also rotates.

[Embodiment] The structure of the drive device of the present invention will be described in more detail below with reference to an embodiment shown in the drawings. First, regarding an electric mechanism, 1 is a motor, 2 is a motor pinion, and 3 is meshed with the pinion. An electric gear, the sun gear 4 on the front
On the rear surface, a ratchet gear 5 that engages with the ratchet 5'is connected. Further, 6 is a spider inserted between the electric gear 3 and the spool shaft, 8 is a plurality of planetary gears rotatably supported by the spider via pins 8 ', and the sun gear 4 And the internal gear 9 is meshed. Further, the internal gear 9 is connected to the bail arm 10 via a base 10 'connected to the tip portion 9'.

Next, regarding the manual mechanism part, 11 is a handle, 12 is a manual shaft rotated by the handle, 13 is a manual gear fitted to the manual shaft 12, and a ratchet 14 'is engaged with a ratchet 14' on its side surface. A gear 14 is connected, and a worm shaft 15 transmits the rotation of the manual gear 13 to the spider 6.

On the other hand, the spool shaft 7 is provided with a Napier thread groove 16 on the tip side thereof, and a protrusion 16 'formed at the central portion of the base 10' slides in the groove so that the spool shaft 7 is Although it is arranged to move back and forth, in this case, the gist of the present invention is not changed even if other known means is used.

In the figure, 17 is a drag for adjusting the pressure contact force of the multi-plate clutch 18 to control the rotating torque of the bail arm 10, 19 is a machine casing, and 20 is a spool at the tip of the spool shaft 7.

The operation of both the mechanical parts will be described. When the motor 1 is driven by a switch (SW), the sun gear 4 rotates together with the electric gear 3, and the planetary gears 8 rotate accordingly. In this case, the spider No. 6 does not rotate because the ratchet gear 14 on the side of the manual gear engages with the ratchet 14 ', so the planetary gear 8 rotates and the internal gear 9 on its outer periphery rotates and is mounted on its tip 9'. The bail arm 10 on the base 10 'rotates integrally.

When the handle 11 is rotated, the manual shaft 12 and the manual gear 13 are rotated in synchronization with this, and the spider 6 is rotated via the worm shaft 15, so that each planet supported by the spider is supported. The gear 8 revolves around the sun gear 4. In this case, the sun gear does not rotate because the ratchet gear 5 coupled to the sun gear engages with the ratchet 5 '. Therefore, the planetary gear 8 revolves around the sun gear in the stopped state to rotate the internal gear 9, and the base of the tip portion 9'of the planetary gear 8 rotates.
10 'and the bail arm 10 rotate together.

Therefore, for example, when a large fish or the like is caught during electric winding of the yarn and the hoisting speed is reduced by the driving force of the motor 1, the planetary gear 8 can be revolved faster by the handle 11 via the spider 6. The manual driving force is preferentially transmitted to the internal gear 9, and a large hoisting force is obtained, and at the same time, the load on the motor 1 is reduced and the seizure accident or the like can be prevented.

That is, with respect to the rotation of the internal gear 9 by the electric mechanism portion and the manual mechanism portion, the mechanism portion that rotates the internal gear 9 at any high speed via the planetary gear 8 that meshes therewith has priority, and the other drive mechanism portion. Not only does this have no effect on, but both can be used together at an appropriate speed.

In the above configuration, if the sun gear 4 is directly rotated by the motor 1 in a fixed direction and a ratchet mechanism is attached to the sun gear to prevent reverse rotation, the electric gear 3
Can be omitted.

[Effect of device]

According to the present invention, the electric mechanism and the manual mechanism can be selectively or simultaneously used without any operation of the switching lever or the like according to the above-described configuration, and the structure is extremely simple, so that the number of components is small. It does not impair the operability of spinning reels, whose small size and light weight are important factors.

Therefore, when the bait is replaced, the tip of the road thread can be fastened electrically and quickly, and also when interacting with fish, both manual and electric preferential simultaneous use are possible. Speed is obtained.

Further, the above-mentioned both drive mechanism parts do not adversely affect the other mechanism part such as co-rotation of the handle or seizure due to overload of the motor due to its structure, so that it is easy to operate. The functionality of this type of spinning reel can be greatly enhanced.
