DETAILED DESCRIPTION OF THE INVENTION
DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a spring-spring power generator embodying the present invention will be described with reference to the drawings. The case 2 of the mainspring type power generation device 1 is formed in a rectangular parallelepiped shape with a width of about 420 mm, a depth of about 270 mm, and a height of about 180 mm by a wooden plate (a metal plate, a resin plate, etc.). A pair of wheels 4 are pivotally attached to the left end portions of the pair of long side plates 2a of the case 2 via an axle 3, and a large U-shaped handle 5 is attached to the right end portion so as to be tiltable. .
[0012]
A first mounting plate 6, a second mounting plate 7, and a third mounting plate 8 are arranged substantially horizontally at the lowermost part, the lower part and the upper part in the case 2, respectively, and the mounting plates 6 to 8 are the bottom plate 2 b of the case 2. And a long support bar 9 inserted through the top plate 2c and screwed thereto, and a short support bar 10 inserted through the bottom plate 2b and screwed into the case 2 to be fixed to the case 2.
[0013]
A vertical input shaft (first shaft) 12 is rotatably supported by a bearing 11 on the left side of the center of the first mounting plate 6 and the third mounting plate 8 in FIG. 2, and the upper end of the input shaft 12 is from the top plate 2c. Projects upward. A square bar-shaped engaged portion 13 is formed at the upper end of the input shaft 12, and a lever-like handle 14 for manually rotating the input shaft 12 is formed at the engaged portion 13 at the front end thereof. By engaging in the hole-shaped engaging part 15, it attaches so that attachment or detachment is possible.
[0014]
Two spring springs 16 and 16 are arranged coaxially and arranged concentrically on the input shaft 12 in parallel. The inner ends of the springs 16, 16 are attached to the input shaft 12, and the outer ends are attached to a stay 17 supported between the first attachment plate 6 and the third attachment plate 8. Each spring 16, 16 is formed by winding a spring steel thin plate having a width of about 50 mm and a length of about 20 m in a spiral shape. The number of windings is 36 in the loose state and 55 in the tightened state. Therefore, the number of rotations of the input shaft 12 caused by the restoration from the wound state to the loose state is 19 times. At present, it is difficult to obtain a wide spring spring, and therefore it is effective to use two or more spring springs together as in this embodiment. In addition, even if one spring spring is cut off, there is also an advantage that power generation can be continued with the other spring spring (although the capacity is reduced).
[0015]
A ratchet mechanism 18 that pawls the input shaft 12 is provided between the first mounting plate 6 and the second mounting plate 7. The ratchet mechanism 18 includes a claw wheel 19 having a large number of claws attached to the input shaft 12, a detent arm 20 that is pivotally attached to the second mounting plate 7 and engages one of the claws of the claw wheel 19, One end is fixed to the second mounting plate 7 and includes a presser spring 21 that urges the detent arm 20 toward the claw wheel 19, and a release lever 22 that extends from the detent arm 20 to the outside of the case 2. The ratchet mechanism 18 allows the input shaft 12 to be manually rotated counterclockwise in FIG. 3 by allowing the detent arm 20 to ride over the pawl of the ratchet wheel 19 in one direction, and then the input shaft 12 rotates clockwise. The detent arm 20 is stopped when the detent arm 20 is engaged with one of the claws of the claw wheel 19. Further, when the release lever 22 is operated from outside the case 2 to be hooked on a hooking portion (not shown) of the case 2 and the detent arm 20 is detached from the ratchet wheel 19, the clockwise rotation of the input shaft 12 is returned. It becomes possible.
[0016]
On the upper surface of the second mounting plate 7 near the right end in FIG. 2, a generator 23 that generates electric power by rotational movement is mounted downward. The generator 23 uses a 18.5 volt dynamo (commutator rectifier generator) for generating voltage (DC full wave).
[0017]
Between the first mounting plate 6 and the second mounting plate 7, the rotation of the input shaft 12 generated by the restoration of the mainspring springs 16, 16 from the tightened state to the loosened state is accelerated and transmitted to the generator 23.

The first mounting plate 6 and the second mounting plate 7 have a second shaft 26, a third shaft 27, a fourth shaft 28, and a fifth shaft in order from the input shaft (first shaft) 12 to the right in FIG. 29 are rotatably supported by the bearings 11 respectively. A first gear 31 having 140 teeth is overlapped and attached to the claw wheel 19 of the input shaft 12. A second gear 32 having 13 teeth and a third gear 33 having 56 teeth are coaxially attached to the second shaft 26, and the first gear 31 and the second gear 32 are engaged with each other. A fourth gear 34 having seven teeth and a fifth gear 35 having 60 teeth are coaxially attached to the third shaft 27, and the third gear 33 and the fourth gear 34 are engaged with each other. A sixth gear 36 having 6 teeth and a seventh gear 37 having 60 teeth are coaxially attached to the fourth shaft 28, and the fifth gear 35 and the sixth gear 36 are engaged with each other. An eighth gear 38 having seven teeth is attached to the fifth shaft 29, and the seventh gear 37 and the eighth gear 38 are engaged with each other. The fifth shaft 29 is joined to the rotating shaft of the generator 23. Therefore, the final speed increase ratio between the input shaft 12 and the fifth shaft 29 is (140/13) × (56/7) × (60/6) × (60/7) = 7344.6.
[0018]
A flywheel 39 is coaxially attached to the eighth gear 38 on the fifth shaft 29, and the generator 23 rotates more stably by inertial rotation of the heavy flywheel 39.
