Description

  The present invention relates to a momentum conversion band that is attached to a body part and converts momentum.

  2. Description of the Related Art Conventionally, there have been proposed some devices that generate electric power by movement of a body part. For example, there are a device that generates electric power by turning a handle by hand and a device that generates electric power by exercise of a body. Therefore, a device that generates electricity by rotating it by hand has good power generation efficiency, but lacks momentum as exercise of the whole body. Further, as a device for generating electric power by body movement, for example, Japanese Patent Application Laid-Open No. 2000-84137 has been proposed, in which a generator is turned by a pendulum that rotates by the movement of a wrist attached to a wristband to generate electric power. There is. However, in the configuration, when the wrist performs an arc-like movement around the shoulder as in jogging or running, as shown in FIG. 17, the hand is swung up and down, or the hand is swung down. When the pendulum swings, the center of gravity of the pendulum exerts a force on (the direction of) the rotation axis, so that the force is almost absorbed by the rotation axis, and the pendulum does not act in the direction of rotation of the rotation axis as the rotation force. There was a great loss of power. Therefore, it is not a device capable of generating electricity by efficiently and efficiently using a kinetic energy generated by an arc-like movement of a wrist to a generator. Further, as a configuration in which a rotating weight, a mainspring, and a generator are provided in a wristwatch and the generator is generated, for example, JP-A-2002-311161 and JP-A-2003-279666 are known. The configuration is largely different from the configuration of the invention in the following two points. First, as one point, the known configuration is a configuration in which the rotary weight winds the mainspring when rotating in both directions due to swinging or vibration, and since a large rotating force cannot be obtained with that configuration, large power generation and charging (power storage) can be obtained. Absent. As another point, the known configuration is such that a generator is rotated by a mainspring to generate electric power, and the generated electric power is used to self-control the rotational speed of the rotor to electrically apply an electromagnetic brake to keep the rotational speed of the rotor constant. This configuration is not a configuration in which the storage battery is charged (stored) with the power generated by rotating the generator in the mainspring as a driving power source. (However, there is a known configuration in which a generator is directly turned by a rotary weight without a mainspring, and the generated electricity is sequentially charged to a storage battery (power storage).) Any known configuration requires large power generation and charging. It was not an obtained configuration.

  The present inventor has filed Japanese Patent Application Laid-Open No. 2004-52747 as an invention to solve these problems. According to the configuration of the present invention, a downward force can be efficiently transmitted when the arm is swung down to the center of gravity of the pendulum, and the number of revolutions of the generator increases in proportion to the speed of swinging down the arm, and the power generation amount also increases. It is. However, an AC generator having a high power generation efficiency has a large self-inducing action, and requires a large torque to rotate the generator. Therefore, in order to generate power, it was necessary to continue by increasing the weight of the pendulum and the speed of swinging down the arm.

There is also.

  The present invention will be described with reference to the drawings.

  FIG. 1 shows an embodiment of the configuration of the present invention. 1 (a) and 1 (b) are perspective views partially showing the whole of the present invention, FIG. 1 (c) shows an expanded state thereof, and FIG. 1 (b) is a side view of the present invention mounted on a hand. The state of is shown. As shown in the figure, a storage section 1A is provided in the band 1, and an open / close section (not shown) is formed on the back side thereof. A storage battery holder 12 for storing the storage battery 8 is provided in the storage section 1A. The pendulum 2 is formed of an appropriately thick wedge-shaped aluminum material, and its center of gravity 2a (x in the drawing) is located at a position far away from the support shaft 4f. When an external force or gravity is applied, the pendulum 2 moves to the center of gravity 2a. In order to move in the direction in which the force acts, the pendulum 2 starts rotating around the support shaft 4f. Stoppers 7 and 7a are provided on the base 16, and the rotating pendulum 2 is stopped from moving in the rotating direction by the stoppers 7 and 7a.

  The configuration of the present embodiment will be described in detail with reference to FIGS. 2, 3, and 4. The pendulum 2 is integrally connected to one side of the shaft coupling 4b and is loosely fitted to the support shaft 4f, and one side of the shaft coupling 4b. The ratchet 4d and the small gear 4a2 are integrally connected, and a spiral spring 6 is provided in the ratchet 4d as shown in FIG. 3D, and one end thereof is fixed to the support shaft 4f. A downward force is always applied to the ratchet wheel 4d by the tension spring 4c2, and the pawl 4e and the pawl portion of the ratchet wheel 4d are locked to each other. In this state, the ratchet wheel 4d is shown in FIG. Only rotate in the direction of the arrow. Then, simultaneously with the rotation of the ratchet wheel 4d in the direction of the arrow, the spiral spring 6 provided in the ratchet wheel 4d is sequentially wound in the direction of the arrow. When the spiral spring 6 is wound in the direction of the arrow, the pawl wheel 4d exerts a rotational force in the direction opposite to the arrow due to the restoring force, but the pawl 4e is locked and the rotation is stopped.

As described above, when the pendulum 2 rotates between the stoppers 7 and 7a following the swing of the arm, the shaft joints 4b and 4b provided between the pendulum 2 and the ratchet 4d shown in FIG. By operation, the rotation of the pendulum 2 in both directions is transmitted by the rotation of the ratchet 4d in only one direction. The shaft joint 4b, which rotates integrally with the pendulum 2, is constantly pressed by an appropriate force by the compression spring 4c1 adjacent to the holding plate 17, so that the two bodies can move right and left on the shaft of the support shaft 4f. . In this state, as shown in FIG. 2 (b), the shaft joints 4b and 4b which are in contact with each other are engaged with each other for the rotation in the direction B on the pendulum 2 side in the drawing, and the rotation in the direction B is a pawl. The rotation in the direction A is not transmitted to the ratchet wheel 4d because the shaft couplings 4b and 4b that are transmitted to the wheel 4d and in contact with each other in the rotation in the direction A slide against each other.
In the configuration of this embodiment, when the arm shown in FIG. 16 is swung up and down, a swinging force is applied to the pendulum 2 following the movement, and by the time the arm is swung up to FIG. As the force applied to the center of gravity 2a of the pendulum 2 is increased by the addition of the inertial force and the centrifugal force, the force of the upward acceleration is applied, and is applied to the center of gravity 2a of the pendulum 2 before the arm is swung down to FIG. The force is the sum of the inertia force + the centrifugal force + gravity plus the increased downward acceleration. Therefore, in any case, a force that follows the swing of the arm is applied to the pendulum 2, but since the weight of the arm and the pendulum 2 is excessively added in the direction in which the arm is swung down, the torque applied to the pendulum 2 increases accordingly. In particular, if the arm is swung down at an acceleration greater than the gravitational acceleration, the force for pushing down the pendulum 2 by the stopper 7a continues to be exerted while the arm is swung down, and the force for rotating the pendulum 2 in the tangential direction to the center of gravity acts greatly. If the stopper 7a is provided at the forefront of the pendulum 2, the force for pushing down can be transmitted to the maximum. In FIG. 1B, even if the pendulum 2 rotates in the A direction by the operation of raising the arm again after reaching the point B in FIG. 1B, the shaft couplings 4b and 4b are configured to transmit in only one direction. By the rotation in the direction A, the reverse rotation force is not exerted on the ratchet wheel 4d. When the ratchet 4d is rotated by the rotation of the pendulum 2, the spiral spring 6 built in the ratchet 4d is wound, and at the same time, the small gear 4a2 is rotated, and the large gear 4a1 meshing with the small gear 4a2 is moved in the direction of the arrow. Rotate. The ratchet wheel 4d and the cam 4g on the large gear 4a1 are integrally connected and loosely fitted to the support shaft 4f, and as shown in FIG. The downward force is always applied by the action of the spring 4c, the pawl 4e and the ratchet 4d are locked, and the pawl 4d and the cam 4g rotate only in the direction of the arrow. The large gear 4a1 and the ratchet 4d are connected via the shaft couplings 4b and 4b, and the compression spring 4c1 always presses the large gear 4a1. The gear 4a1 and the ratchet 4d and the cam 4g rotate integrally in the direction of the arrow in FIG. 3A, but in the direction of the arrow in FIG. 3B, the ratchet 4d is operated by the shaft couplings 4b and 4b. Does not rotate in either direction. When the pendulum 2 rotates, the ratchet wheel 4d and the small gear 4a2 rotate, and the large gear 4a1 meshing with the small gear 4a2 rotates. At the same time, the cam 4g rotates at the same angular velocity as the large gear 4a1. A convex portion 4h is formed on a part of the circumferential side surface of the cam 4g, and the pawl 4e is always pulled downward by a tension spring 4c. The cam 4g rotates to change from FIG. 3 (a) to FIG. 3 (b). In this state, the projection 4h pushes the pawl 4e down as shown in the figure, and in the state shown in FIG. 3B, the pawl 4e is released from the locked state with the pawl 4d, and at the same time, the pawl 4d and the small gear 4a2 starts to rotate in the direction of the arrow in the figure. At this time, the ratchet wheel 4d, the shaft couplings 4b, 4b, and the pendulum 2 also rotate in the direction A in FIG. 1 (b) while being connected. As shown in FIG. 4 (b), the stopper 7a is connected to the scissor-shaped spring 4c3. When the side end of the pendulum 2 reaches the stopper 7a by the pendulum 2 which is in an inverted U-shape by an appropriate force and is released in the latched state and rotates in the direction A, the stopper 7a 4C, the stopper 7a pushes the lower surface of the pendulum 2 upward, as shown in FIG. 4C. When the pendulum 2 is lifted upward, the shaft couplings 4b and 4b are separated from the contact surfaces with each other in this state and the locking state is released, so that the ratchet 4d is completely free, and the built-in spiral spring With the restoring force of 6, the ratchet wheel 4d and the small gear 4a2 are rotated at the same time, and simultaneously the generator gear 4a3 is rotated, so that the AC generator 3A (or the DC generator 3B) starts generating power. Then, the AC generator 3A (or the DC generator 3B) continues to rotate and generates power until the spiral spring 6 is in the original unwound state. Here, when the generator 3 tries to rotate at an accelerated speed by the restoring force of the spiral spring 6, the self-inducing action is correspondingly large, and as a result, the generator 3 tries to rotate at a constant rotation and works to keep the power generation constant. The AC generator 3A may be constituted by a three-phase AC generator. The stopper 7a does not rotate unless a certain force is applied thereto. When the state shown in FIG. 4C is reached, the pendulum 2 is sandwiched between the stopper 7a and the holding plate 17. That state is maintained by the action of the compression spring 4c1.

As shown in FIG. 5, when the AC generator 3A (or the DC generator 3B) rotates, an AC electromotive current i flows. When the current i becomes a flowing current, and the current i is smoothed by a smoothing circuit, the current i becomes a current i close to a direct current and is sequentially stored (charged) in the storage battery 8. As the storage battery 8 is charged (charged), the charging voltage between its electrodes gradually increases. Assuming that the charging completion voltage is Vs, the charging completion voltage Vs and the charging voltage Vo during charging between the electrodes are calculated. When the voltage / current detection determination circuit 13 makes a comparison, if Vo> Vs, for example, the storage (charging) of the storage battery 8 is stopped, and a blue LED for notifying the completion of charging can be configured to emit light. Alternatively, as another embodiment, the illustrated LED 10a1 may be configured of a two-color LED of blue and red, and may be configured to light blue when charging is completed. In this configuration, the storage (charging) of the storage battery 8 may also be configured to be energized and stored (charged) only while the latch release mechanism is operating. When the pendulum 2 reaches the point A and is stopped by the stopper 7a, the lower surface of the pendulum 2 is detected by the reflection type sensor 14, and a pulse signal is formed by the sensor 14, and the pulse number is calculated by the pulse counting unit 5 shown in FIG. Is counted. The pulse counting unit 5 detects the state of the hand being swung up by the movement of the pendulum 2 by the sensor 14, and detects and counts one pulse as one hand-swinging operation. Then, as shown in the figure, the pulse counting section 5 operates the notifying means 10 in accordance with the appropriate counted number. In the present embodiment, the notification means 10 is configured to display the LEDs 10a1 to 10a4 and the liquid crystal display 10b in a lighting state. With this configuration, for example, the count number is sequentially displayed on the liquid crystal display 10b, or every time the count number increases by 300. The LEDs 10a1 to 10a4 can be configured to be sequentially turned on. For example, if you wave your hand 300 times, the count number becomes 300 and the LED 10a1 turns on. If you wave your hand 300 times (total 600 times), the LED 10a2 turns on. If you wave your hand 300 times (total 900 times), the LED 10a3 turns on. It can be configured such that the LED 10a4 is turned on when the user turns on the light and shakes his hand 300 more times (1200 times in total). The count number here is not limited to 300, but may be set to 200, 400, 500 as appropriate. The way of lighting the LEDs 10a1 to 10a4 may be such that the LEDs 10a1 to 10a4 are always turned on one by one or may be turned on one by one while increasing one by one. The pulse counting unit 5 can be implemented by, for example, a decimal BCD counter SN74LS90, a counter IC 74HC160, or the like. When the battery 15 housed in this configuration is exhausted and the replacement time has come, the opening / closing portion formed on the back side of the band 1 can be opened and removed, and the battery 15 can be replaced. In the configuration of this embodiment, if the storage battery 8 is fully charged (charged) from the beginning, the LED 10a1 is turned on in blue from the beginning, and stops charging (charging) the storage battery 8. Can be configured to suppress excessive power storage (overcharge). Further, the battery 8 may be configured to prevent excessive discharge (overdischarge). Further, a switch may be provided so as to be able to be turned ON / OFF in order to suppress unnecessary consumption of the built-in battery 15. By connecting an electrolytic capacitor in parallel to the smoothing circuit in the rectifier 9 in FIG. 5, the waveform can be smoothed to a waveform close to DC. When the storage battery 8 is composed of a lithium-ion storage battery, its charge state is 4.2 (V). Therefore, the storage battery 8 may be composed of a voltage doubler rectifier circuit shown in FIG. A voltage rectifier circuit or a triple voltage rectifier circuit may be used.
In the state shown in FIG. 3C, the projection 4h is rotated to the position shown in the figure, and at the same time, the pawl 4e is pushed up to the original position, and the pawl 4e and the ratchet wheel 4d are locked again. When the pawl 4e enters the locked state, the spiral spring 6 returns to the original state, and the state shown in FIG. 3B is maintained while the generator 3 is rotating. The gear ratio between the large gear 4a1 and the small gear 4a2 may be set appropriately, and the number of protrusions 4h formed on the cam 4g is not limited to one, but may be two or more. Each time, the latch state is released and the generator 3 can be rotated. Further, the width of the convex portion 4h may be appropriately set, so that the latch release state can be set for a predetermined number of times. In this configuration, the number of revolutions and the speed at which the generator 3 rotates after the latch is released are kept constant each time.

The configuration of this embodiment will be described with reference to FIGS. 14, 15, and 16 in a state where the band 1 is actually attached to the wrist. The band 1 fits tightly on the wrist. In this state, when the wrist is swung up and down as shown in FIG. 16, the pendulum 2 rotates to the point A in FIG. 1B until the hand in FIG. 16A is swung up. Similarly, the pendulum 2 rotates to the point B in FIG. 1B before the hand in FIG. 16D and FIG. 16E is swung down. While rotating from the point A to the point B, the ratchet 4d rotates and the spiral spring 6 is wound.
When the wrist (arm) is swung up and the wrist is swung down successively, the rotating spring 6 stores the rotating restoring force sequentially.

An outer shell integrated with the portion 3a is configured to be rotated together with the small gear 4a2 and the ratchet wheel 4d. With this configuration, when the above-described latch mechanism is released, the outer electromotive unit 3a of the AC generator 3A rotates to start generating electric power using the induced electromotive force.

By wrapping the band 1 around the wrist and bringing the hook-and-loop fasteners 1b and 1b into contact with each other, the band 1 can be attached to the wrist and fixed firmly. In the configuration of this embodiment, as shown in FIG. 9, in the configuration of the transmission unit 4, an electromotive unit 3a in an AC generator 3A and a magnetic body 3b fixed to a support shaft 4f are provided in a ratchet 4d. The ratchet wheel 4d and the electromotive unit 3a rotate integrally by the restoring force of the spiral spring 6.
In the configuration of the present embodiment, for example, a mainspring may be provided on the support shaft 4f of the pendulum 2 so as to rotate to the point A in FIG. 1B by itself and return.

If the size of the storage battery 8 is a battery shape, a versatile size of AAA is appropriate. Whether or not the storage (charging) of the storage battery 8 has been completed can be confirmed by, for example, the lighting state of the LED 10a1 with the same configuration in FIG. For example, the connector 11 may be configured so as to be connected and extended by a connection wire.

In the configuration of FIG. 12, the small gear 4a2 that rotates by the rotation of the pendulum 2 is configured to mesh with and rotate with the small gear 4a2 that is integral with the ratchet wheel 4d, and is configured as shown in FIGS. As compared with the above, the ratchet wheel 4d and the built-in spiral spring 6 can be rotated and wound with a small rotation torque of the pendulum 2.
