Description

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

  2. Description of the Related Art Conventionally, several devices that generate electric power by exercise of a body part have been proposed. Therefore, in a device that generates power by turning it by hand, the power generation efficiency is good, but the exercise of the whole body is poor in momentum. Further, as a device for generating electricity by body movement, for example, Japanese Patent Laid-Open No. 2000-84137 has been proposed, and in the configuration therein, a generator is rotated by a pendulum that is rotated by movement of a wrist attached to a wristband to generate electricity. There is. However, in that configuration, when the wrist makes an arc-shaped movement around the shoulder, such as jogging or running, as shown in FIG. 17, when the hand is swung up and down, or the hand is swung down and swung up Since the center of gravity of the pendulum acts on the rotation axis (in the direction), the force is almost absorbed by the rotation axis, and the rotation of the pendulum does not work in the direction of rotation of the rotation axis as a rotating force. There was a big power loss. Therefore, it was not a device that can generate power by using the kinetic energy generated by the arcuate movement of the wrist to the generator efficiently without waste. In addition, there are, for example, Japanese Patent Application Laid-Open No. 2002-311661 and Japanese Patent Application Laid-Open No. 2003-279666 in which a rotating weight, a mainspring, and a generator are provided in a wristwatch, and the generator generates electric power. The configuration differs greatly from the configuration of the invention in the following two points. First, as one point, the known configuration is a configuration in which the main body of the rotary weight is swung or vibrated to rotate in both directions, and a large rotational force cannot be obtained with this configuration, so that large power generation and charging (storage) can be obtained. Absent. As another point, the known configuration is such that a power generator is rotated by a mainspring to generate electric power, and the rotational speed of the rotor is self-controlled by the generated electricity to electrically apply an electromagnetic brake so that the rotational speed of the rotor is constant. The configuration is not a configuration that charges (accumulates) a storage battery using electricity generated by rotating a power generator with a mainspring as a driving power source. (However, there is a configuration in which a power generator is directly rotated by a rotating weight without providing a spring in a known configuration, and the generated electricity is sequentially charged (accumulated) in a storage battery.) It was not the structure obtained.

  As an invention for solving these problems, the present inventor has applied for Japanese Patent Application Laid-Open No. 2004-52747. According to the configuration of the present invention, when the arm is swung down to the center of gravity of the pendulum, the downward force can be efficiently transmitted, and the number of rotations of the generator is increased in proportion to the speed at which the arm is swung down, and the power generation amount is also increased. It is. However, an AC generator with high power generation efficiency has a large self-induction effect, and requires a large torque to turn the generator. Therefore, in order to generate electricity, it was necessary to continue with increasing the weight of the pendulum and the speed of swinging down the arm.

  The present invention has been made after a trial study in view of the above-described problems. The kinetic energy generated by the body part is temporarily stored as the energy of the spiral spring by the movement of the body part of the body (especially the wrist and ankle). It is to provide a momentum conversion band that turns a machine, efficiently converts it into electric energy without waste, charges a stable power generation amount to a storage battery, and activates a notification means according to the detected momentum and the number of exercises.

  In the present invention, since the kinetic energy generated by the local body part is temporarily converted into the energy of the spiral spring by the movement of the local body part (especially wrist and ankle) of the body, the generator can be rotated to generate power. Energy can be efficiently stored in the storage battery. Further, by combining the gear ratio, the spiral spring can be wound with a small torque, and the generator can be rotated by converting the rotation of the spiral spring at a high speed, so that power can be generated very efficiently.

Therefore, power generation and charging can be performed even in everyday life, and the appropriate weight serves as a dumbbell. There is also.

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

  FIG. 1 shows one embodiment of the configuration of the present invention. 1 (a) and 1 (b) show a perspective view of a part of the whole of the present invention, FIG. 1 (c) shows a developed state thereof, and FIG. 1 (b) shows a side view in which the present invention is mounted on a hand. Shows the state. As shown in the figure, the band 1 is provided with a storage portion 1A, and an opening / closing portion (not shown) is formed on the back side. A storage battery holder 12 for storing the storage battery 8 is provided in the storage section 1A. The pendulum 2 is formed of a wedge-shaped aluminum material having an appropriate thickness, and its center of gravity 2a (x in the figure) is located far away from the support shaft 4f. When the external force or gravity is applied to the pendulum 2, the center of gravity 2a The pendulum 2 starts rotating about the support shaft 4f in an attempt to move in the direction in which the force works. Stoppers 7 and 7a are provided on the base 16, and the rotating pendulum 2 is stopped from moving in the direction of rotation 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 loosely fitted to the support shaft 4f, and one side of the shaft coupling 4b. The pawl wheel 4d and the small gear 4a2 are integrally connected, and a spiral spring 6 is provided in the pawl wheel 4d as shown in FIG. 3 (d), and one end thereof is fixed to the support shaft 4f. The downward force by the tension spring 4c2 is always applied to the pawl wheel 4d, and the pawl 4e and the pawl portion of the pawl wheel 4d are engaged with each other. In this state, the pawl wheel 4d is illustrated in FIG. It rotates only in the direction of the arrow. Simultaneously with the rotation of the pawl wheel 4d in the direction of the arrow, the spiral spring 6 provided in the pawl 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 is rotated in the direction opposite to the arrow by its 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 pawl wheel 4d shown in FIG. In operation, the pendulum 2 is rotated in both directions to rotate in only one direction of the pawl wheel 4d. A shaft coupling 4b that rotates integrally with the pendulum 2 is always pressed by an appropriate force by a compression spring 4c1 adjacent to the presser plate 17, and both bodies can move freely on the shaft 4f. . In this state, as shown in FIG. 2 (b), the shaft couplings 4b and 4b that are in contact with each other have both protrusions engaged with each other for rotation in the B direction on the side of the pendulum 2 in the figure, and the rotation in the B direction is pawl. Since the shaft couplings 4b and 4b that are transmitted to the vehicle 4d and are in contact with each other in the rotation in the A direction slide with each other, the rotation in the A direction is not transmitted to the pawl wheel 4d.
With the configuration of this embodiment, when the arm swings up and swings down as shown in FIG. 16, a force is applied to the pendulum 2 to follow the motion and until the arm is swung up to FIG. 16 (a). The force applied to the center of gravity 2a of the pendulum 2 is a force increased by an upward acceleration by adding an inertial force + a centrifugal force, and is applied to the center of gravity 2a of the pendulum 2 until the arm is swung down to FIG. The force is the sum of the inertial force + centrifugal force + downward acceleration with gravity added. Therefore, in both cases, 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 added in the direction of swinging the arm, the torque applied to the pendulum 2 increases accordingly. In particular, if the arm is swung down with an acceleration greater than the gravitational acceleration, the force that pushes down the pendulum 2 by the stopper 7a continues to work while the arm is swung down, and the force that rotates the pendulum 2 in the tangential direction is greatly exerted. If the stopper 7a is provided at the forefront of the pendulum 2, the force of pushing down can be transmitted to the maximum. Even if the pendulum 2 is rotated in the A direction by the operation of swinging up the arm again after reaching the point B in FIG. 1B, the above-described shaft couplings 4b and 4b are configured to transmit in only one direction. The reverse rotational force does not reach the pawl wheel 4d by the rotation in the A direction. When the pawl wheel 4d is rotated by the rotation of the pendulum 2, the spiral spring 6 built in the pawl wheel 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 pawl wheel 4d and the cam 4g on the large gear 4a1 are integrally connected and loosely fitted to the support shaft 4f. As shown in FIG. 2C, the pawl 4e forming the ratchet mechanism portion 4A has a scissors shape. A downward force is always applied by the action of the spring 4c, the pawl 4e and the pawl wheel 4d are locked, and the pawl wheel 4d and the cam 4g rotate only in the direction of the arrow. The large gear 4a1 and the pawl wheel 4d are connected via the shaft couplings 4b and 4b, and the compression spring 4c1 always presses the large gear 4a1. In the direction of the arrow in (a), the large gear 4a1, the pawl wheel 4d and the cam 4g rotate integrally. In the direction of the arrow in FIG. 3 (b), the pawl wheel 4d is operated by the shaft couplings 4b and 4b. Does not rotate in either direction. When the pendulum 2 rotates, the pawl wheel 4d and the small gear 4a2 rotate, and when the large gear 4a1 meshing with the small gear 4a2 rotates, 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 peripheral side surface of the cam 4g, and the pawl 4e is always pulled downward by a tension spring 4c, and the cam 4g rotates to rotate the cam 4g from FIG. 3 (b) to FIG. 3 (b). In this state, the projection 4h pushes down the pawl 4e 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 wheel 4d and at the same time, the pawl wheel 4d and the small gear 4a2 begins to rotate in the direction of the arrow in the figure. At this time, the pawl wheel 4d, the shaft couplings 4b, 4b, and the pendulum 2 are connected and rotate in the direction A in FIG. 1B, but as shown in FIG. 4B, the stopper 7a is formed of the scissors spring 4c3. When the side end of the pendulum 2 reaches the stopper 7a by the pendulum 2 that is upright in an inverted U shape by an appropriate force and is released in the locked state and rotates in the direction A, the stopper 7a At the same time, the stopper 7a pushes the lower surface of the pendulum 2 upward as shown in FIG. 4C. When the pendulum 2 is moved upward, the shaft couplings 4b and 4b are separated from the contact surfaces in this state, and the locked state is released. Therefore, the pawl wheel 4d is completely free, and the spiral spring incorporated therein. With the restoring force of 6, the pawl wheel 4d and the small gear 4a2 are rotated together, and at the same time, the generator gear 4a3 is rotated, and the AC generator 3A (or DC generator 3B) starts generating electricity. The AC generator 3A (or DC generator 3B) continues to rotate and generates power until the spiral spring 6 is not wound. Here, if the generator 3 tries to rotate at an accelerated speed by the restoring force of the spiral spring 6, the self-inducing action works correspondingly, and as a result, the generator 3 tries to rotate at a constant rotation and keeps the power generation amount constant. The AC generator 3A may be a three-phase AC generator. The stopper 7a does not rotate unless a certain force is applied, and when the state shown in FIG. 4 (c) is reached, the pendulum 2 is sandwiched between the stopper 7a and the presser plate 17. The state is maintained by the action of the compression spring 4c1.

As shown in FIG. 5, when the AC generator 3 </ b> A (or DC generator 3 </ b> B) rotates, an AC electromotive current i flows, and when this AC electromotive current i flows through the rectifying bridge diode circuit in the rectifying unit 9, When the current i flows and the current i is smoothed by the smoothing circuit, the current i becomes a direct current 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. When the charging completion voltage is Vs, the charging completion voltage Vs and the charging voltage Vo during charging between the electrodes are When the voltage / current detection determination circuit 13 compares and Vo> Vs, as an example, the storage (charging) of the storage battery 8 is stopped, and a blue LED notifying the completion of charging can be configured to emit light. Alternatively, as another embodiment, the illustrated LED 10a1 can be configured by two-color LEDs of blue and red, and can be configured to light blue when charging is completed. With this configuration, power storage (charging) to the storage battery 8 may also be configured to store power (charge) only while the latch release mechanism is operating. When the pendulum 2 comes to the point A and is stopped by the stopper 7a, the lower surface of the pendulum 2 is detected by the reflective sensor 14, a pulse signal is formed by the sensor 14, and the number of pulses is detected by the pulse counting unit 5 shown in FIG. Is counted. The pulse counting unit 5 detects the hand swinging state due to 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 unit 5 operates the notification means 10 in accordance with the appropriate counted number. In this embodiment, the notification means 10 is configured to turn on the LEDs 10a1 to 10a4 and the liquid crystal display 10b. 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. It can comprise so that LED10a1-10a4 may be lighted in order. For example, if the hand is shaken 300 times, the count number is 300 and the LED 10a1 is turned on. If the hand is shaken 300 times (total 600 times), the LED 10a2 is turned on, and if the hand is shaken another 300 times (total 900 times), the LED 10a3 is turned on. It can be configured such that the LED 10a4 is lit when it is turned on and waved for another 300 times (total of 1200 times). The count number here is not limited to 300, and may be configured to be appropriately set to 200, 400, or 500. Also, the LEDs 10a1 to 10a4 may be turned on one by one in order, or may be configured to turn 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 stored in this configuration is consumed and the replacement time is reached, the opening / closing part 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 sufficiently charged (charged) from the beginning, the LED 10a1 is in a blue lighting state from the beginning, stops storing (charging) the storage battery 8, and the storage battery 8 It can be configured to suppress excessive power storage (overcharge). Moreover, you may comprise so that the excessive discharge (overdischarge) of the storage battery 8 may be prevented. Further, a switch may be provided to turn on / off in order to suppress wasteful consumption of the built-in battery 15. By connecting an electrolytic capacitor in parallel to the smoothing circuit in the rectifying unit 9 in FIG. 5, the waveform can be smoothed to a waveform close to direct current. Further, when the storage battery 8 is constituted by a lithium ion storage battery, the charged state is 4.2 (V), so it may be constituted by a voltage doubler rectifier circuit shown in FIG. A voltage rectifier circuit or a triple voltage rectifier circuit may be used.
In the state of FIG. 3 (c), the convex portion 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 pawl wheel 4d are again locked. When the pawl 4e is in the locked state, the spiral spring 6 is returned to its 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 convex portion 4h formed on the cam 4g may be formed not only at one location but also at two or more locations, whereby a predetermined number of times of swinging the arm. Each time the latch state is released, the generator 3 can be rotated. Further, the width of the convex portion 4h may be set appropriately, whereby the state of latch release can be set for a predetermined number of times. In this configuration, the number of rotations and the speed at which the generator 3 after latch release rotates are kept constant each time.

14, 15, and 16, the configuration of this embodiment will be described with the wrist 1 actually attached to the wrist. When the band 1 that expands and contracts with a rubber material is inserted into the wrist and fitted, the state shown in FIG. 14B is obtained. Band 1 fits tightly on the wrist. When the wrist is swung up and down in this state as shown in FIG. 16, the pendulum 2 rotates to the point A in FIG. 1B until the hand in FIG. Similarly, the pendulum 2 rotates to the point B in FIG. 1B until the hand in FIGS. 16D and 16E is swung down. While rotating from the point A to the point B, the claw wheel 4d rotates and the spiral spring 6 is wound.
Then, when the wrist (arm) swinging up and swinging down operations are continuously performed, the restoring force that rotates in the spiral spring 6 is sequentially stored.

In this configuration, when the latch mechanism described above is released, the outer electromotive unit 3a of the AC generator 3A rotates and starts generating power by the induced electromotive force.

FIG. 8 shows an embodiment of the configuration of the present invention, in which hook and loop fasteners 1b and 1b (registered trademark: Velcro) are provided at both ends of a band 1 made of a resin material so as to come into contact with each other. 1 is wound around the wrist and the surface fasteners 1b and 1b are brought into contact with each other, so that the band 1 can be attached to the wrist and firmly fixed. In the configuration of this embodiment, as shown in FIG. 9, in the configuration of the transmission section 4, an electromotive section 3a in the AC generator 3A and a magnetic body 3b fixed to the support shaft 4f are provided in the pawl wheel 4d. The pawl wheel 4d and the electromotive portion 3a are configured to rotate integrally with the restoring force of the spiral spring 6.

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

It can be confirmed on the screen of a mobile phone or PDA, and can also be configured to function as a storage medium for music playback (MP3 player). As a card-type storage medium, it can be implemented with a Panasonic SD memory card or a Sony memory stick.
