Description

The present invention relates to a mechanism for storing rotational force by storing rotational force in a coil spring.

Conventionally, the mainspring is used as a device for storing and storing metal hysteresis, but it has a narrow range of use due to its structural characteristics, and it can be used as a power source for toys and table clocks, as well as for storing power cords and tape measures. However, it was not used for general purposes.

The winding device is limited to a flat structure from the top, and is only used for winding a power cord of some electric products.

Recently, there are winders for personal computer USB cables and portable terminal headset cords, and the use of winder devices has expanded. The use was limited.

The mainspring accumulates metal hysteresis directly in the rotational direction and releases it, so it is simple in terms of mechanism, but as mentioned above, it lacks versatility, so it has a highly versatile coil spring and can store rotational force. It is convenient if possible.

The present invention realizes a rotational force accumulating mechanism using a coil spring, which has not existed in the prior art, and converts rotational force of a coil spring into rotational force to store rotational energy.

The coil spring fixed to the stator is expanded and contracted by the rotational force of the rotor that is rotatably supported by the stator, and is bred.

FIG. 1 is a diagram showing a basic structure using a strap attached to the proposed means for storing rotational force in a coil spring. In the present invention in a normal state, the coil spring is in a relaxed state, so that the strap is also tensioned. Not. When rotation is applied to the rotor, the strap is wound around the rotating shaft, and the strap pulls the coil spring in accordance with this, whereby the coil spring is fed.

In other words, the rotation applied to the rotor is converted to energy storage of metal hysteresis, which is called a coil spring, and in the description of the basic structure in FIG. 1, the rotational force is stored by winding the strap. This is an example.

And, by having a latitudinal mechanism for preventing reverse rotation and an escapement mechanism for gradually releasing the accumulated rotational force, it can be used in the same way as a conventional mainspring, and it could not be realized with a mainspring. This makes it possible to achieve rotational power storage in the application field.

In the above explanation, the basic operation is described for an example in which a strap is wound. However, by using a pinion rack mechanism or by using a slider that slides along a spiral rail, the rotational force is converted into a reciprocating force. There is also a means of accumulating power.

Although the present invention can be considered as a mechanical part that replaces the mainspring using metal hysteresis, it can be further advanced to realize a large-scale energy storage device that could not be realized by the mainspring. If a recoil starter is attached to the power generator to store human power, and the generator is driven, the possibility of use as a power source for a personal computer is expanded.

Coil springs are versatile and inexpensively produced in other varieties, and a coil spring with a size and expansion / contraction force can be selected according to the purpose, making it possible to realize a human power generator with various power generation outputs. Similarly, various shapes can be realized.

If the size is further increased, for example, it is possible to obtain electric power sufficient to drive a home appliance.

Embodiments of the present invention will be described below with reference to the drawings.
2 to 4 are examples in which the coil spring is a compression spring, and a strap winding portion is built in the coil spring, and the strap is wound to compress the coil spring to store energy.

The cylindrical rotor 200 is rotatably supported on the stator 100 by a bearing B via a rotating shaft 250. The rotating shaft 250 has a strap winding portion 255, and a metal wire strap 300 ( The other end of the coil spring 400 is fixedly coupled to a hook 405 at the front end of the coil spring 400 via a guide pulley 350.

In FIG. 2, the normal state is shown, and no force is applied to the rotor 200. Therefore, the strap 300 is bent and the coil spring 500 is not stored and is in a relaxed state.

When the rotor 200 rotates, the rotating shaft 250 also rotates, so that the strap 300 is guided to the guide pulley 270 and is wound around the winding portion 255 from the lateral direction. Accordingly, the tip of the coil spring 400 is pulled and compressed.

When the rotor 200 continues to rotate and the strap 300 is wound around the winding portion 255, the coil spring 400 is pulled in the compression direction by the strap 300 as shown in FIG. .

When the rotor 200 continues to rotate and the strap 300 is all wound up, as shown in FIG. 4, the coil spring 400 is pulled and compressed to the vicinity of the compression limit, and the maximum energy is stored.

As described above, the rotation applied to the rotor 200 is stored as energy in the form of a livestock of the coil spring 400, and the ratchet mechanism and escapement mechanism are provided so that this energy storage is not immediately released. By having it, it functions as a rotational force accumulating mechanism that performs the same operation as the mainspring.

5 to 7 show examples of the present invention in which rotation applied to the rotor 200 is converted into a reciprocating force of the rack 650 by the pinion rack structure, and the coil spring 400 is pressed and stored by this reciprocating force. This will be described. .

The pinion 600 is fixed to the stator 100 via a pinion rotation support shaft 650. FIG. 5 shows a non-accumulation state. When the rotor 200 rotates from this normal state, the rotation is transmitted to the pinion 600 via the bevel gear 500, thereby pushing down the rack 650 and pressing the coil spring coupled thereto. Then, accumulation is started.

When the rotor 200 continues to rotate and the pinion 600 continues to rotate, thereby further pushing down the rack 650, the coil spring 400 is further compressed and stored as shown in FIG.

Further, when the rotor 200 continues to rotate and the rack 650 is pushed down to the lowest position, the coil spring 400 is further pressed accordingly, and the maximum rotational accumulation force is performed as shown in FIG.

8 to 10, a spiral rail 205 is provided on the inner peripheral surface of the rotor 200, and a slider 4500 having a sliding protrusion 455 that fits and slides on the spiral rail 205 is attached to the coil spring. This will be described as an example of the present invention.

FIG. 8 shows a normal non-power storage state. When rotation is applied to the rotor 200 from this normal state, the sliding protrusion 455 slides along the spiral rail 205, and thereby the coil spring together with the slider 450. 400 is depressed.

When the rotor 200 continues to rotate and the slider 450 further slides and moves as shown in FIG. 9, the coil spring 400 is further pressed in accordance with this and further rotation accumulation is performed.

When the rotor 200 continues to rotate and the slider 450 slides to the vicinity of the lower end of the spiral rail 205, the coil spring 400 is pressed to the vicinity of the compression limit accordingly, and the maximum rotation is performed as shown in FIG. Accumulation is done.

FIG. 11 shows an example having a ratchet mechanism 800 for preventing reverse rotation. This enables rotational accumulating without reverse rotation even with human power applied by a force that does not keep the rotational force stable, and allows the rotor 200 to rotate. Continues accumulating rotational force without reversing even when power is no longer applied.

Further, as shown in FIG. 12, the rotor 200 and the rotary shaft 250 are coupled via a reduction gear 900 to adjust the reduction ratio, thereby adjusting the rotation speed of the rotor 200 and the expansion / contraction stroke of the coil spring 400. By changing the ratio, it is possible to perform rotational accumulation of force according to the purpose of use.
