First, the rack gear 12 is carved on the manual handle 11 that reciprocates via the return panel 11a, and the pinion gear 13 is mounted on the rack gear 12 as shown in FIG. Convert the reciprocating motion into rotational motion by meshing.

In the present invention, “manual” means automatic, and is not limited to manual operation, but also includes operation using a foot-operated petal. Therefore, the handle includes a foot-operated petal. Including.

Then, a transmission gear 14 a, 14 b, 14 c for increasing or decreasing the speed is connected to the pinion gear 13, and the handle 11 is reciprocated to the left and right of the transmission gear 14. A dowel gear 15 provided with a dovo mechanism for allowing the gear rotating in the reverse direction to rotate in one direction is connected to the gear.

As shown in FIG. 2, the dowel gear 15 is provided with a rim gear 15 f having an inner tooth 15 e coaxial therewith via a shaft gear 15 a and a shaft 15 b, as shown in FIG. An arm 15c is pivotally mounted on b, and a claw 15d meshing with the internal teeth 15e is rotatably mounted on the arm 15c.

When the shaft gear 15a rotates to the right in the figure, the claw 15d pivotally attached to the arm 15c rotates. It is swung outward by the centrifugal force, meshes with the internal teeth 15 e of the rim gear 15 ί, and the rim gear 15 f also rotates. On the other hand, when the shaft gear 15a rotates to the opposite side, the pawl 15d does not mesh with the internal teeth 15e and becomes idle, and the rotation of the shaft gear 15a is not transmitted to the rim gear 15f. That is, as for the rotation of the shaft gear 15a, only rotation in one of the left and right directions is transmitted to the rim gear 15f, and the opposite rotation is not transmitted.

The dovegear gear 15 meshes with a rotary gear 17 which is mounted on a rotary shaft 18 of a three-phase AC generator 19 via a transmission gear 16.

In the above description, the case where the handle 11 is moved by hand is shown. However, as shown in FIG. 3, the handle 11 may be a stepped petal type. In this case, the structure of the power generation mechanism 10 is the same.

It is desirable that the rotor of the generator 19 be an outer rotor in order to increase electromotive force by strong centrifugal force.

A rectifier is connected from the three-phase AC generator and converted to DC, and DC power is supplied to a mobile phone or the like via a socket.

Next, the excessive torque avoiding mechanism section 20 is provided in the power generating mechanism section 10 and, as shown in FIG. 4, as a part of the transmission mechanism, for example, a part of the transmission gear 14. The output shaft 22 is arranged and interposed between them.

On the outer edges of the input shaft 21 and the output shaft 22, grooves 21a and 22a are formed. Then, as shown in FIG. 5, a cylindrical body 23 fitted to the input shaft 21 and the output shaft 22 is formed, and the cylindrical body 23 can be opened and closed via a hinge portion 24. A convex part 23a that fits with the concave grooves 21a and 22a of the input shaft 21 and the output shaft 22 is formed in a part of the cylindrical body 23, and the open edge 25 of the cylindrical body 23 A hole 26 is formed in the hole 26, and a stopper 28 having a spring 27 applied with a force exceeding a certain force to hold the edge 25 in the closing direction is disposed therein.

The hinge part 24 is provided with a leaf spring 23a as shown in FIG. 6 or a force for urging the hinge part 24 into the open side as a plate panel form, or as shown in FIG. To It may be set.

In addition, the concave grooves 21 a and 22 a of the input shaft 21 and the output shaft 22 and the convex portion 23 a of the cylindrical body 23 may be reversed.

Next, the power adjusting section 30 is provided with two or more generators 31 a, 31 b, 31 c in the power generating mechanism section 10, and a power transmission from the dovo mechanism. Connect the rotating shafts of multiple generators to the gears.

The two or more generators 3 la, 31 b, 31 c-· are provided with a series circuit and a parallel circuit and connected to each other, and between the series circuit and the parallel circuit, A switching switch 32a, 32b- ', which allows the user to select the circuit, is provided.

As another embodiment, two or more generators 31a, 31b, 31c 'are arranged, and a circuit between them is connected in series (Fig. 8A) or in parallel (Fig. 8B), or However, it is also possible to use a circuit (Fig. 8C) that mixes these.

Further, as shown in FIGS. 10 to 14, the lock mechanism 40 has a hook receiver 11 b formed on a part of the handle 11, and a hook receiver 11 is formed on the main body side of the generator 11 in contact with the handle 11. A room 41 is formed, and a force 42 normally immersed in the room and a hook 42 for protruding a face out of the room when necessary are arranged in the hook storage room 41. In addition, a slide groove 41a in which an operation knob 44b described later slides is formed in a part thereof.

The hook body 42 supports a rotation shaft 43 at one end and forms a piece board 44 having a hook groove 44a at the tip end. Panels 45 are provided on a part of the piece board 44 and the main body side. It is provided with an operation knob 44b interposed and sliding along the slide groove 41a.

Next, the operation of the portable generator of the present invention will be described.

In order to use the portable generator of the present invention, the handle 11 is gripped and pressed repeatedly. At this time, the handle 11 has a hand pressing force in the case shown in FIG. 1 and a stepping step in a petal type as shown in FIG.

Then, the rack gear 1 2 connected to the handle 1 1 rotates the pinion gear 1 3 H

Then, the shaft gear 15 a of the dowel gear 15 is rotated via the transmission gear 14. Then, due to the action of the dowel mechanism, one of the left and right rotations is transmitted to the rim gear 15 f with respect to the shaft gear 15 a that rotates left and right by the reciprocating motion of the handle 11.

Therefore, the reciprocating motion of the handle is converted into left and right rotational motion by the rack gears 12 and the pinion gears 13, and then, by the transmission gears 14 a, 14 b, and 14 c, from the left and right rotations by the single gear 15. A rotational force is generated in one direction, and the rotational force causes the generator 19 to rotate smoothly. Then, the generated electromotive force is supplied to a mobile phone, a mobile computer, a mobile radio, and the like via a socket.

Next, when a certain load or more is applied to the handle 11 for some reason, the present invention avoids a force that causes a large load to break the mechanism and cause a failure.

That is, normally, the cylinder 23 is closed by the elasticity of the panel 27 of the excessive torque avoiding mechanism 20 and the rotational force from the input shaft 21 is reduced by the concave grooves 2 la and 22 a and the convex part. The torque is transmitted to the output shaft 22 by the concave and convex fit with the 23a, and the torque from the input shaft 21 is transmitted as it is to the output shaft 22 (see Fig. 4).

However, when a large load exceeding a certain level occurs on the input shaft 21, the edge 25 of the cylindrical body 23 rotates in the opening direction beyond the elastic force of the spring 27 due to the large rotation torque. The panel 27 contracts, and the cylindrical body 23 opens via the hinge 24 (see FIG. 5B). As a result, the concave portion 21a of the input shaft 21 and the concave portion 22a of the output shaft 22 are disengaged from the convex portion 23a, and the rotational force from the input shaft 21 is transferred to the output shaft side. Is not transmitted. Therefore, if something happens to the steering wheel 11, for example, when a load is dropped on the petal in the case of step-type power generation, a large torque is generated in the gears and the like as it is, and parts may be damaged, causing failure. This can be avoided. Next, when two or more generators 31a, 31b, 31c- are provided and a power adjustment leak 30 is provided, the series circuit and the parallel circuit are switched by the switching switch 32a, 3 2 b--allows the user to make his own choice. When a series circuit is selected by the switching switches 32a and 32b- ', the voltage of the electromotive force of each generator can be integrated, which is suitable for, for example, a notebook computer requiring a high voltage. If a parallel circuit is selected, the value of the supplied current can be increased, and for example, it becomes suitable for charging a mobile phone.

Therefore, a single portable generator can supply voltage and current according to the use of a mobile phone, a mobile computer, a mobile lamp, a mobile radio, etc., and has high versatility.

Also, when two or more generators are arranged and a series or parallel circuit or a mixed circuit is used between them, the types of generators to be arranged are unified and the number of parts is reduced. As well as lower manufacturing costs. Further, the lock mechanism 40 of the handle operates as follows. First, usually, the hook body sinks into the hook storage chamber 41 around the rotation axis 43 by the urging force of the spring 45 and does not come out of the face, and the projection of the hook body 42 does not come out. In doing so, there is no danger of injury, etc., and the system is safe (see Fig. 11).

Then, if you want to fold the handle, when you pull the operating knob 4 4b and slide it in the left and right direction, it slides along the fitted slide groove 41a, which is centered on the rotating shaft 43. And the piece plate 44 is rotated against the elastic force of the panel 45. Then,鉤体4 2 force had ^sunk? Kaowodasu from a hook storage room 4 1 (see FIG. 1 2).

When the handle 11 is folded in the folding direction and the operating knob 4 4b is released, the return force of the spring 45 rotates the piece plate 4 4 around the rotating shaft 4 3 in the returning direction, and the operating knob 4 4 b slide grooves 4 1 a end ^force? fit engagement Kagi受1 1 b and the force engagement was arranged to hook groove 4 4 a and the handle 1 1 at the position of being locked in a collapsed condition the handle 1 1 forces (See Figure 13).

Therefore, the whole is compact and portable. Industrial applicability Based on the above configuration, the present invention can supply electricity for power generation and charging to a portable telephone, a portable personal computer, a portable radio, and the like without a power supply, and in using the same, an overload on a steering wheel is required. This is an advantageous invention that can avoid the trouble due to the above, can adjust the voltage or current of the electric power to be supplied as needed, and can achieve various effects such as folding the handle and carrying it compactly.
