  However, in the above-described conventional drive device, when the drive shaft is continuously rotated by intermittently driving the flywheel, it rotates at a high rotational speed immediately after starting, but rotates in a short time. It stopped and the drive shaft could not be rotated continuously for a long time.

  For this reason, it has been inconvenient as a drive source for a generator or the like that is used continuously for a long time.

  Therefore, in the present invention according to claim 1, a drive device is provided in parallel with the drive shaft, wherein the drive shaft is continuously rotated by attaching the flywheel to the drive shaft and intermittently driving the flywheel. The swinging body is attached to the rotating shaft, the swinging body and the flywheel are connected by the first link, the rotational motion of the flywheel is converted into the reciprocating motion of the swinging body, and the second link is connected to the swinging body. At the same time, the second link is connected to the flywheel via a one-way clutch, and one side of the reciprocating motion of the oscillator is converted into the rotational motion of the flywheel.

  The specific configuration of the drive device according to the present invention will be described below with reference to the drawings.

[First embodiment]
As shown in FIG. 1 and FIG. 2, the driving apparatus 1 according to the first embodiment has support bodies 3 and 4 formed on the upper portion of the base 2 with a space left and right.

  The left support 3 has a pair of support plates 5 and 6 arranged at intervals in the front-rear direction, and a drive shaft 7 extended in the front-rear direction is attached to the upper ends of the support plates 5 and 6 while being rotatably supported. A disc-shaped flywheel 8 disposed between the plates 5 and 6 is vertically attached to the drive shaft 7. Thereby, the flywheel 8 can be rotated up and down (left and right) together with the drive shaft 7.

  On the other hand, the right support 4 is a rotation in which a pair of support plates 9, 10 are arranged at a distance in the front-rear direction and extended in the front-rear direction so as to be parallel to the drive shaft 7 at the upper ends of the support plates 9, 10. The shaft 11 is rotatably attached, and a midway part of the swinging body 12 extended vertically is attached to the rotating shaft 11. As a result, the oscillator 12 reciprocates left and right together with the rotating shaft 11. The oscillator 12 has a length on the upper end side of the rotating shaft 11 that is longer than a length on the lower end side of the rotating shaft 11.

  The drive device 1 connects the flywheel 8 (drive shaft 7) and the upper end of the oscillating body 12 by the first link 13, and also connects the lower end of the oscillating body 12 and the flywheel 8 (drive shaft 7). Are connected by a second link 14 to link the flywheel 8 (drive shaft 7) and the rocking body 12 together.

  The first link 13 has a proximal end portion of the first drive arm 15 attached to the drive shaft 7, and a proximal end portion of the first driven arm 16 is vertically (left and right) at the distal end portion of the first drive arm 15. The tip end of the first driven arm 16 is attached to the upper end of the oscillating body 12 so as to be rotatable up and down (left and right). Here, the drive shaft 7 is arranged coaxially in the front and rear, and each drive shaft 7 is rotatably supported by the support plates 5 and 6, and the rear end portion of the front drive shaft 7 and the rear The base end portion of the first drive arm 15 is attached to the front end portion of the drive shaft 7 on the side, and the base end portion of the first driven arm 16 is attached between the front end portions of the first drive arms 15 and 15. Yes. In FIG. 1, illustration of the front support plates 5 and 6 is omitted.

  Thus, when the drive device 1 rotates the flywheel 8 up and down (left and right), the first drive arm 15 together with the drive shaft 7 rotates up and down (left and right), and accordingly the first driven arm 16 is moved. The oscillating body 12 connected via the oscillating member reciprocally swings left and right within a certain angle range. That is, the drive device 1 converts the rotational motion of the flywheel 8 into the reciprocating motion of the oscillator 12 by the first link 13.

  In addition, the second link 14 is attached to the lower end portion of the oscillating body 12 so that the base end portion of the second drive arm 17 is pivotable up and down (left and right), and the second link 14 is attached to the tip end portion of the second drive arm 17. The base end of the follower arm 18 is pivotably mounted vertically (left and right), and the tip end of the second follower arm 18 is connected to the drive shaft 7 via a one-way clutch 19. The one-way clutch 19 transmits power from the second driven arm 18 to the drive shaft 7 to rotate the drive shaft 7 only when the second driven arm 18 moves leftward from right to left. When the driven arm 18 moves rightward from left to right, the power of the second driven arm 18 is not transmitted to the drive shaft 7 but is idled.

  Thus, when the driving device 1 swings the rocking body 12 left and right by rotating the flywheel 8 up and down (left and right), the second driven arm 18 connected via the second driving arm 17 is moved. Rotates the drive shaft 7 (flywheel 8) only when the left and right reciprocates and one side of the reciprocating motion of the second driven arm 18 (here, the second driven arm 18 moves to the left). The power to be transmitted is transmitted. In other words, the drive device 1 rotates the flywheel 8 on one side of the reciprocating motion of the oscillating body 12 (one side in the direction of motion. Here, the side moving leftward from right to left) by the second link 14. Convert to

  In the drive device 1, the drive shaft 7 can be continuously rotated by attaching the flywheel 8 to the drive shaft 7 and intermittently driving the flywheel 8.

One side of the reciprocating motion of the moving body 12 is converted into the rotational motion of the flywheel 8.

  Therefore, in the drive device 1 configured as described above, part of the energy for rotating the flywheel 8 is again (delayed) through the first link 13, the rocking body 12, the second link 14, and the one-way clutch 19 in order. It will act to rotate the wheel 8. Thereby, in the drive device 1, the rotational speed immediately after starting is not rapidly reduced, and the drive shaft 7 can be continuously rotated over a long period of time, such as a generator used continuously for a long period of time. It can be used as a drive source.

  In addition, by attaching a load to a position shifted from the center of gravity (drive shaft 7) of the flywheel 8 (for example, on the outer peripheral edge), an uneven load is provided on the flywheel 8 so that the load drops when the one-way clutch 19 is idling.
