Description

  The present invention relates to a power generation apparatus that generates power by a manual operation and operates various devices using the generated power.

  Conventionally, a power generation device that generates power by manual operation, etc., and operates various devices using the generated power without requiring external power supply, simplifies the structure of various devices from the viewpoint of environmental protection. It has been developed for the purpose. For example, in a cabinet equipped with a locking / unlocking device, in order to secure the power used by the locking / unlocking device, a power generation device that generates power by operating the handle of the cabinet is provided. It can be used without being conscious of the fact that it is performing (see, for example, Patent Document 1).

  In addition, a technique has been developed in which power is generated by an operation such as a manual operation, and transmission is performed using the generated power. For example, there is a technique in which a piezoelectric element that generates electricity in response to operation of an operation lever is built in a crescent lock, and the information is transmitted to another when the lock state of the crescent lock is released (for example, see Patent Document 2). .

  However, in the power generation device described in Patent Document 1, the rotating shaft portion (operation portion) that is rotated by the operation of the handle portion is linked to the energy accumulation movable member (energy accumulation means), and the energy accumulation movable member is When moving from the accumulator position to the standby position by the urging force of the coil spring, the transmission claw of the accumulator movable member is engaged with the gear section of the power generation section, and this gear section is rotated. Thereafter, the transmission pawl is disengaged, and the gear portion is freely rotated by inertia to generate power in the power generation portion. That is, when the pulling part is pulled by the user, the coil spring extends, and the restoring force of the coil spring when the hand is released from the pulling part rotates the gear part of the power generation part, so the speed at which the user pulls the pulling part. Depending on the degree of separation when the user removes the hand from the handle part, it may not be possible to secure a stable power generation amount.For example, when the user slowly releases the handle part, the restoring force of the coil spring is accumulated. It is not transmitted sufficiently to the force movable member, and the moving speed of the force accumulation movable member becomes weak, and it becomes impossible to secure an effective power generation amount enough to operate the locking / unlocking device (actuating part), and the power amount intended for the locking / unlocking device Cannot be given, and there is a risk that the locking and unlocking device will not operate.

  Further, in the power generation device described in Patent Document 2, one of the steel balls fixed to both ends of the support beam is disposed at a position where the piezoelectric power generation device can be beaten, and the operation lever is rotated. As a result, the other hard sphere strikes and vibrates by the driven gear actuating body that rotates forward and reverse, and with the vibration of the other hard sphere, one of the hard spheres starts co-vibration. The power is generated by hitting the power, and the information on the locked or unlocked state of the locking device is transmitted using the generated power. That is, the amount of vibration of the hard sphere changes depending on the operation amount and operation speed of the operation lever, the number and strength of striking the piezoelectric power generation device change, and the power generation amount changes accordingly. Therefore, the power generation device described in Patent Document 2 has a problem that it takes time to obtain a predetermined voltage, and the predetermined power cannot be obtained at a necessary timing.

  EMBODIMENT OF THE INVENTION The form for implementing the electric power generating apparatus which concerns on this invention is demonstrated below based on an Example.

  The power generation apparatus according to Embodiment 1 will be described with reference to FIGS. Reference numeral 1 in FIG. 1 is a fixture 1 installed in an office or the like. The fixture 1 is provided with a double door 2. On the front surface of the door 2, there are a handle part 3 for opening the door 2, a knob part 4 (operation part) for locking and unlocking the door 2, and an opening / closing operation of the door 2 by the knob part 4. A numeric keypad 9, an indicator 10 and a solar cell 11 constituting an authentication means for authentication are provided. The handle portion 3 is linked to a latch mechanism (not shown) so that the door 2 is not inadvertently opened by the latch mechanism, and the latch mechanism is released by gripping the handle portion 3 so that the door is opened. 2 can be opened.

  As shown in FIG. 2, a power generator 6 to which the present invention is applied is provided inside the door 2. The power generation device 6 includes the knob 4 described above, and locks and unlocks the door 2 and is also linked to an authentication unit, and an operator permitted to authenticate by the authentication unit performs locking and unlocking. Can do.

  Next, the authentication means includes a numeric keypad 9 for the user to input a personal identification number, an indicator 10 for notifying the user whether or not authentication is permitted, and an electric circuit according to a control signal based on the input of the numeric keypad 9. 5 has a switch 33 that switches between a conductive state and a non-conductive state, and a control unit 35 that is connected to perform authentication judgment and the like (see FIG. 5). The numeric keypad 9 and the indicator 10 are disposed on the front surface of the door 2.

  Further, the authentication means of the first embodiment is operated by the electric power supplied from the solar cell 11. This authentication means performs only electrical processing by an electric circuit and does not operate a physical machine or the like. Therefore, a weak light source such as an indoor lamp installed on the ceiling side of an office or the like is used. Even a very small amount of electric power generated by the solar cell 11 is sufficiently operated.

  Then, the control unit 35 of the authentication means determines whether or not the password entered by the user with the numeric keypad 9 matches the authentication number registered in advance, and the password and the authentication number match. When the authentication is permitted, the switch 33 in the power generation device 6 to be described later is controlled to be in an ON state that is an energizable state, and the indicator 10 is turned on. Further, when the password is not matched with the authentication number and the authentication is rejected, the switch 33 is controlled to be in an OFF state that is not energized and the indicator 10 is blinked.

  In addition, the controller 35 of the authentication means is provided with a battery (not shown) that stores the power generated by the solar cell 11. Note that an LED display may be used instead of the indicator 10 to notify the user of whether or not authentication is possible.

  The power generation device 6 has an operating member 7 (predetermined object) that is a rectangular bar-shaped member for making the door 2 unopenable, and this operating member 7 is in the engagement direction (left direction). As a result, the front end portion is inserted into and engaged with a receiving seat 8 formed on the other door 2, and the door 2 cannot be opened. Further, when the operation member 7 is moved in the release direction (right direction), the distal end portion thereof is detached from the receiving seat 8 formed on the other door 2, and the door 2 can be opened.

  Next, the power generation device 6 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 2, the power generation device 6 is provided on the rear surface side of the front plate 12 that constitutes the front surface of the door 2, and the power generation device 6 has an upper and lower side for guiding the operation member 7 linearly. A guide portion 14 formed of two ridges is provided. The operation member 7 can move in the left-right direction along the guide portion 14.

  The knob 4 described above has a substantially circular shape when viewed from the front, and is disposed on the front plate 12 to constitute an operation means. An operation gear 65 that is rotated simultaneously with the rotation of the knob 4 is provided on the rear surface side of the knob 4. The tooth portion 66 of the operation gear 65 is formed on a part of the circumference of the circular operation gear 65. In addition, the knob | pick part 4 and the operation gear 65 are relatively fixed by the interlocking shaft 67 (refer FIG. 4). Further, on the rear surface side of the operation gear 65, an operation pin 22 provided in the vicinity of the circumference of the operation gear 65 is provided.

  As shown in FIG. 6, a long hole 20 that extends vertically for engaging with the operation pin 22 is formed in the operation member 7 that is a predetermined target. When the operator rotates the knob 4, the operation gear 65 is rotated in the circumferential direction, and the position of the operation pin 22 is moved along with the rotation of the operation gear 65. The force is transmitted from the long hole 20 to the operation member 7 through the operation pin 22. In the fourth embodiment, when the operator rotates the knob 4 counterclockwise, the operation member 7 moves in the engagement direction (left direction), and the operator rotates the knob 4 clockwise. Thus, the operation member 7 moves in the detaching direction (right direction).

  By operating the knob 4 in this manner, the rotation direction of the operation gear 65 and the movement direction of the operation member 7 are operated in the engagement direction (forward direction) or the release direction (reverse direction), respectively. Yes.

  Moreover, the generator 68 (electric power generation part) is attached to the rear part of the mounting bracket 39 of the electric power generating device 6 (see FIG. 4). The generator 68 generates a direct current (first function). A power generation gear 69 (movable member) that drives the generator 68 is provided above the operation gear 65. The power generation gear 69 is fixed relative to the drive shaft 71 of the generator 68, and the power generation gear 69 is rotated about the drive shaft 71. A tooth portion 70 is formed on the entire circumference of the power generation gear 69, and the tooth portion 66 of the operation gear 65 is engaged therewith.

  Furthermore, the power generation gear 69 has a pair of left and right coil springs 25 configured as elastic members having elasticity at the left and right ends thereof. One end of the coil spring 25 is attached to the power generation gear 69, and the other end of the coil spring 25 is attached to the mounting bracket 39. The power generation gear 69 is rotatable in the circumferential direction. However, the power generation gear 69 is stably held at a fixed position in the circumferential direction by the urging forces of the left and right coil springs 25. ing. The coil spring 25 constitutes the elastic member in the first embodiment.

  Further, in the vicinity of the right end side of the guide portion 14, a substantially circular rotating body 27 that is rotatable by a rotating shaft 26 is provided. A part of the rotating body 27 is cut out linearly to form a cutout portion 28 (non-regulated portion). As shown in FIG. 6, when the rotating body 27 is rotated and the cutout portion 28 is in the lower position, the operating member 7 can move to the detachment position on the rightmost side. As shown in FIG. 14, when the rotating body 27 is rotated and the cutout portion 28 is in the upper position, a restricting portion 28 a (a restricting portion) that is a part of the rotating body 27 is disposed inside the guide portion 14. Thus, the operation member 7 comes into contact with the rotating body 27 and its movement is restricted (locked).

  As shown in FIG. 6, a permanent magnet 29 having magnetism is provided inside the rotating body 27. The rotating body 27 is rotated by applying a magnetic force to the permanent magnet 29 from the outside. When the cutout portion 28 of the rotating body 27 is in the lower position, the direction of the magnetic pole of the permanent magnet 29 is N pole on the left side and S pole on the right side. An electromagnet 30 that applies a magnetic force to the rotating body 27 is disposed above the rotating body 27. The electromagnet 30 has a coil formed of a copper wire arranged around an iron core. The rotating body 27 constitutes the operating part in the first embodiment.

  As shown in FIG. 5, two electric wires 32 extend from the generator 68, and the electric wires 32 are connected to the coil of the electromagnet 30. The electric wire 32 is provided with an ON / OFF switch 33 that is controlled by the authentication means described above. When the authentication is permitted, the switch 33 between the generator 68 and the electromagnet 30 is turned on. If authentication is not possible, the switch 33 between the generator 68 and the electromagnet 30 is turned off.

  As shown in FIG. 6, when the operator performs a locking operation, authentication is first performed by the authentication means described above. When the authentication is permitted, the switch 33 between the generator 68 and the electromagnet 30 is turned on. Thereafter, the operator rotates the knob 4 counterclockwise. Then, the operation member 65 is rotated in accordance with the rotation of the knob 4 so that the operation member 7 is moved in the engagement direction (left direction) (second function).

  As shown in FIG. 7, when the operation member 7 is moved by a predetermined amount, that is, when the operation gear 65 is rotated by a predetermined amount, the tooth portion 66 of the operation gear 65 is engaged with the tooth portion 70 of the power generation gear 69. The gears 65 and 69 are linked to each other. Then, with the counterclockwise rotation of the operation gear 65, the power generation gear 69 is rotated clockwise. As the power generation gear 69 rotates, the left and right coil springs 25 of the power generation gear 69 start to extend.

  As shown in FIG. 8, when the knob 4 is rotated by the manual operation of the operator and the operation gear 65 is continuously rotated, the energy by the manual operation applied to the knob 4 extends the coil spring 25. In the coil spring 25, a stroke associated with the movement of the operation member 7, that is, a part of the stroke associated with the rotation of the knob 4 is stored as mechanical energy that is an extension of the coil spring 25.

  As shown in FIG. 9, when the operation gear 65 is further rotated by a predetermined amount, the tooth portion 66 of the operation gear 65 is disengaged from the tooth portion 70 of the power generation gear 69, and the linkage state of the gears 65 and 69 is cut off from each other ( Unlinked state). Then, the restoring force of the coil spring 25 shortens the coil spring 25 at once, and the energy stored in the coil spring 25 is instantaneously released to rotate the power generation gear 69 counterclockwise.

  The generator 68 generates power by the rotation of the power generation gear 69. At this time, the electric power generated by the generator 68 is a direct current. Furthermore, since the energy stored in the coil spring 25 is instantaneously released, a high voltage can be generated. Note that the tooth release portion 66 of the operation gear 65 is disengaged from the tooth portion 70 of the power generation gear 69 and the linkage state of the gears 65 and 69 is cut off, thereby constituting the instantaneous release means in the first embodiment.

  Specifically, an induced current having a peak as shown in FIG. 3A is generated at a point where the moving speed of the power generation gear 69 urged by the restoring force of the coil spring 25 is the fastest.

  Moreover, the electric power generated by the generator 68 is supplied to the electromagnet 30 disposed above the rotating body 27 via the rectifier 36a of the branch line 32a. The energized electromagnet 30 is temporarily magnetized to generate a magnetic field in which the left end of the electromagnet 30 has an N pole and the right end has an S pole. At this time, due to the magnetic force generated by the electromagnet 30, the permanent magnet 29 inside the rotating body 27 is affected by the magnetic force, so that the rotating body 27 is rotated about the rotating shaft 26 and its direction is switched. Yes. Note that the direction of the rotating body 27 is switched by being rotated 180 °. The operating member 7 can move to the leftmost engagement position regardless of the orientation of the rotating body 27.

  As shown in FIGS. 8 and 9, the cutout portion 28 of the rotating body 27 is disposed at a lower position before the direction of the rotating body 27 is switched. After the electromagnet 30 is energized, a part of the rotating body 27 is arranged in the guide portion 14 after the direction of the rotating body 27 is switched.

  As shown in FIG. 10, when the operator performs unlocking, authentication is first performed by the above-described authentication means (see FIGS. 2 and 5). When the authentication is permitted, the switch 33 between the generator 68 and the electromagnet 30 is turned on. Thereafter, the operator rotates the knob 4 clockwise. Then, the operation gear 65 is rotated in accordance with the rotation of the knob 4 so that the operation member 7 is moved in the detaching direction (right direction) (second function).

  When the operation member 7 is moved by a predetermined amount, that is, when the operation gear 65 is rotated by a predetermined amount, the tooth portion 66 of the operation gear 65 is engaged with the tooth portion 70 of the power generation gear 69, and the gears 65, 69 are mutually connected. It is supposed to be linked. As the operation gear 65 rotates clockwise, the power generation gear 69 rotates counterclockwise. As the power generation gear 69 rotates, the left and right coil springs 25 of the power generation gear 69 start to extend.

  As shown in FIG. 11, when the knob 4 is rotated by the manual operation of the operator and the operation gear 65 is continuously rotated, the energy by the manual operation applied to the knob 4 extends the coil spring 25. In the coil spring 25, a stroke associated with the movement of the operation member 7, that is, a part of the stroke associated with the rotation of the knob 4 is stored as energy for extending the coil spring 25.

  As shown in FIG. 12, when the operation gear 65 is further rotated by a predetermined amount, the tooth portion 66 of the operation gear 65 is disengaged from the tooth portion 70 of the power generation gear 69, and the linked state of the gears 65 and 69 is cut off from each other ( Unlinked state). And the coil spring 25 shortens at a stretch by the restoring force which the coil spring 25 has, the energy stored in the coil spring 25 is instantaneously released, and the power generation gear 69 is rotated clockwise. The generator 68 generates power by the rotation of the power generation gear 69, and an induced current having a peak as shown in FIG. 3B is generated. At this time, the electric power generated by the generator 68 is a direct current like the electric power generated during the locking operation described above, but the polarity of the electrodes is reversed.

  That is, the electric power generated by the generator 68 is supplied to the electromagnet 30 disposed above the rotating body 27 via the switch 33 and the rectifier 36b of the branch line 32b in the opposite direction to the time of locking described above. The electromagnet 30 generates a magnetic field in which the left end portion of the electromagnet 30 is the S pole and the right end portion is the N pole. Thus, the polarity of the electrode of the generator 68 when the knob 4 is operated in the engaging direction (forward direction) and the generator 68 when the knob 4 is operated in the detaching direction (reverse direction). The polarities of the electrodes are reversed from each other.

  The permanent magnet 29 inside the rotator 27 is influenced by the magnetic force generated by the electromagnet 30, and the rotator 27 is rotated around the rotation shaft 26, and the direction is switched. In this manner, the rotating body 27 that operates with the electromagnet 30 can be controlled by the magnetic poles of the electromagnet 30, and the rotating body 27 can be controlled by the operator manually operating the knob 4.

  As shown in FIG. 13, after the direction of the rotating body 27 is switched, the cutout portion 28 of the rotating body 27 is arranged at the lower position, and the operating member 7 can move to the detaching position. The operator can open the fixture 1 and the door 2 by rotating the knob 4 clockwise to move the operation member 7 to the detachment position.

  When the operator performs the locking operation or the unlocking operation, authentication is first performed by the above-described authentication means (see FIGS. 2 and 5). If the authentication is impossible, the generator 68 is used. And the electromagnet 30 are switched off (see FIG. 5). When the operator rotates the knob 4 in this state, the operation gear 65 and the power generation gear 69 are rotated, but the switch 33 between the generator 68 and the electromagnet 30 is in the OFF state. The electromagnet 30 is not energized, and the rotating body 27 is not rotated.

  For example, as shown in FIG. 14, when the authentication is impossible, even if the operator operates the knob 4 when unlocking, the end of the operation member 7 contacts the rotating body 27. The movement is regulated. In this state, the distal end portion of the operation member 7 is inserted and engaged with a receiving seat 8 (engaged portion) formed on the other door 2, and the door 2 can be opened. Can not.

  In the power generator 6 according to the first embodiment, the rotating body 27 that is rotatable by the rotating shaft 26 can switch the direction with a small amount of power (work amount), and the position of the rotating body 27 does not change. By switching the direction, the operation member 7 that physically moves along the guide portion 14 can be restricted or released, and the operation member 7 can be restricted or released with a small amount of electric power. .

  In addition, the rotating body 27 has a permanent magnet 29, and an electromagnet 30 is disposed in the vicinity of the rotating body 27, and the direction of the rotating body 27 is switched by energizing the electromagnet 30. With a simple configuration of the rotating body 27 having the permanent magnet 29 and the electromagnet 30, the operation member 7 can be regulated or released. In addition, the amount of power consumed by the electromagnet 30 only needs to be able to secure the amount of power that can switch the direction of the rotating body 27, and the operation member 7 can be regulated or released with less power consumption. The power generation device 6 can be obtained.

  Further, the direction of the rotating body 27 can be switched by the magnetic force, and it is not necessary to provide a mechanical element such as a spring member that performs a mechanical operation in addition to the rotating body 27 for switching the direction of the rotating body 27. The direction of the rotating body 27 can be switched with a small amount of work.

  Thus, since the electric power generated using the manual operation of the operator is used for the operation of the power generation device 6 having the rotating body 27 that performs the operation of the physical machine, the power consumption of the entire fixture 1 can be suppressed. it can.

  As described above, the operation gear 65 and the power generation gear 69 are linked when the operating member 7 is moved by a predetermined amount by rotating the knob 4 manually by the operator. That is, the operating member 7 is moved along the guide portion 14 by manual operation, and the operation gear 65 and the power generation gear 69 are linked while the operating member 7 is operating in a region away from the rotating body 27 in the guide portion 14. Then, the coil spring 25 is stored by using a part of the operation of the stroke accompanying the movement of the operation member 7 as energy.

  By doing in this way, even if the rotating body 27 is in the direction in which the operating member 7 is regulated or the direction in which the regulation is released, a part of the stroke accompanying the movement of the operating member 7 is applied to the coil spring 25. Can be stored as energy, and the generator 68 generates power using the energy released when the operation gear 65 and the power generation gear 69 are disconnected, and the direction of the rotating body 27 is switched. Sometimes, since the operating member 7 is in a region away from the rotating body 27, there is no possibility that the rotating of the rotating body 27 is obstructed by the operating member 7.

  The power generation gear 69 can be linked to the operation gear 65 at a part of the stroke associated with the movement of the knob 4, and the instantaneous release means is connected to the power generation gear 69 while the coil spring 25 stores energy. The state in which the coil spring 25 stores energy by mechanical energy being instantaneously converted into electric power by the generator 68 and being directly supplied to the electromagnet 30. Thus, the linkage between the power generation gear 69 and the operation gear 65 is cut off by the instantaneous release means, the energy stored in the coil spring 25 is released at once, the energy is instantaneously converted into electricity, and the rotating body 27 The electric power generated can be generated, and the generated electric power is immediately consumed by the electromagnet 30, thereby preventing the loss of electrical energy and generating power. The power generated can be effectively utilized in the machine 68.

  The rotating body 27 is engaged with at least a part of the operating member 7 to regulate the operation of the operating member 7. When the rotating body 27 is operated, the rotating body 27 and the operating member 7 are controlled. By switching between engagement and disengagement, the operation member 7 to be manually operated is regulated by the rotating body 27, and the power generation device 6 can be used as a locking / unlocking device and is added to the operation member 7. The manual operating force can be used immediately for the operation of the rotating body 27, and the electric power generated by the generator 68 can be used effectively while preventing loss of electrical energy.

Is pulled back into the power generator 6c. Then, the control rod 103 is not restricted by the operating member 7, and the latch rod 101 can be rotated, and the operator can open the door 2.

  In the first embodiment described above, the door 2 is directly closed by the operating member 7 so as not to be opened. However, as in the second embodiment, the power generation device 6c is incorporated into a part of the latch mechanism to generate power. By restricting the operation of the latch mechanism by the operation member 7 of the device 6c, the door 2 can be indirectly closed by the operation member 7 so as not to be opened.

Then, in a state where the operation pin 22 is engaged with the linear portion 23 b of the operation hole 23, the user rotates the knob 38 counterclockwise, whereby the operation member 13 is rotated with the rotation of the operation gear 21. Is moved in the left direction, and the user rotates the knob 38 clockwise so that the operation member 13 is moved in the right direction.

  As shown in FIGS. 17A and 17B, the knob 38 is formed with a grip 72 that protrudes forward and extends in the left-right direction and is gripped by the user. Further, a rotating shaft portion 73 protruding in a rod shape is provided on the rear side of the knob portion 38 at the center portion of the rear surface of the knob portion 38. The rotary shaft portion 73 is provided with an operation gear 21 that is fixed relative to the rotary shaft portion 73 and is rotated simultaneously with the rotation of the knob portion 38. Further, in the vicinity of the peripheral edge on the rear surface side of the operation gear 21, an operation pin 22 protruding in a rod shape is provided on the rear side of the operation gear 21.

  The operation gear 21 has an engagement piece 36 that is engaged with an engagement piece 34 that is installed adjacent to the operation gear 21. The engagement piece 36 is formed in a plate shape that extends from the center of the operation gear 21 toward the outer peripheral side of the operation gear 21 and gradually decreases in width as it approaches the distal end portion on the outer peripheral side. Further, the engagement piece 36 and the operation gear 21 are fixed to each other via the rotation shaft portion 73.

  The engaging piece 36 is configured such that the tip of the engaging piece 36 is engaged with the engaged piece 34 when the knob 38 is rotated between a predetermined angle. That is, the engagement piece 36 of the operation gear 21 is engaged with the engagement piece 36 while being engaged with the engaged piece 34 while the operation gear 21 is rotated by a predetermined angle. If the operation gear 21 is further rotated beyond a predetermined angle, the engagement between the engagement piece 36 and the engagement piece 34 is released.

  Further, the engaged piece 34 is formed in a substantially rectangular plate shape extending from the center toward the outer peripheral side, and the front end portion of the engaged piece 34 is the engaging piece 36 of the operation gear 21. To be engaged. Furthermore, the engaged piece 34 and the bevel gear 42 are fixed to each other via an interlocking shaft 37 that faces in the front-rear direction.

  Further, the generator 40 as the power generation unit of the present invention that generates power by rotating the rotating shaft 41 facing the left-right direction is attached to the right end portion of the mounting bracket 63 of the power generation device 60. A bevel gear 44 that meshes perpendicularly to the bevel gear 42 and an engagement body 45 are fixed to the rotating shaft 41 of the generator 40, and the generator 40 has a rotating shaft via the bevel gears 42 and 44. It is driven by the rotation of 41 to generate power.

  In addition, a coil spring 48, which is an extension spring, is disposed on the front side of the generator 40. The coil spring 48 is locked at one end to the engaged piece 34 via a locking material and at the other end. The mounting bracket 63 is engaged with the fixing pin 50.

  As shown in FIG. 21B, the rear end portion of the mounting bracket 63 is provided with a substantially circular rotating body 19 that is rotatable by a rotating shaft. The rotating body 19 is formed with a notch 52 (non-regulated portion) in which a part thereof is notched in a straight line. As shown in FIGS. 21 (c) to 21 (e), when the rotating body 19 is rotated and the cutout portion 52 is in the lower position, the operating member 13 is disengaged from the receiving seat 17 of the fixture 1. It can move in the movement path to the position where it is released. On the other hand, when the cutout portion 52 of the rotating body 19 is in the upper position, a restricting portion 52a (regulating portion) that is a part of the rotating body 19 is arranged in the movement path of the operating member 13, and the operating member 13 contacts. The movement of the operating member 13 is restricted when the part 15a contacts the rotating body 19.

  Further, although not particularly illustrated, a permanent magnet having magnetism is fixedly provided inside the rotating body 19. The rotating body 19 is rotated by applying a magnetic force to the permanent magnet from the outside. Further, as shown in FIG. 18A, an electromagnet 30 formed by winding a copper wire around the iron core in a coil shape is fixedly arranged at a position near the rotating body 19. When a current is applied to the electromagnet 30 at a predetermined timing, a magnetic force is applied to the rotating body 19 so that the notch 52 can be rotated.

  An electrical circuit as shown in FIG. 19 is formed by the above-described switch 33 of the authentication means, the generator 40 of the power generation device 6, and the electromagnet 30. In this electric circuit, the electric generator 40 has electric wires 32 and 32 connected to two electrodes 31 and 31, respectively, and is connected to the coil of the electromagnet 30 via these electric wires 32 and 32. And one of these electric wires 32 has branch lines 32a and 32b branched so as to be branched and joined again. The two branch lines 32a and 32b are provided with rectifiers 36a and 36b for restricting the direction of the current flowing therethrough in one direction, and the current flowing through the branch lines 32a and 32b is forward or reverse. It is designed to flow in different directions. One branch line 32b is provided with the above-described switch 33, and current flows only when the switch 33 is in the ON state.

  Next, as shown in FIGS. 20A to 20D, the operation of the authentication unit by the operator will be described. First, as shown in FIGS. 20A and 20B, the engaging body 45 engaged with the flange portion 56 a of the rotating body 56 is accompanied by an operation in which the operator presses the power switch 74 against the spring member 53. Rotate to a predetermined angle. In accordance with the rotation operation of the engaging body 45, the engaged piece 34 connected via the bevel gears 42 and 44 rotates and the coil spring 48 starts to extend. In the coil spring 48, an operation associated with the pressing operation of the power switch 74 is stored as energy of extension of the coil spring 48.

  When the power switch 74 is further pressed to rotate the engagement body 45 by a predetermined amount, as shown in FIG. 20C, the flange portion 56a of the rotation body 56 is disengaged from the engagement body 45, and the engagement state between the engagement bodies 45 is changed. Refused. And the coil spring 48 is shortened at a stretch by the restoring force which the coil spring 48 has, the energy stored in the coil spring 48 is instantaneously released, and the engaging body 45 is rotated via the engaged piece 34 and the bevel gears 42 and 44.

  The generator 40 generates power by the rotation of the rotating shaft 41 accompanying the rotation of the engaging body 45. At this time, the electric power generated by the generator 40 is a direct current and is temporarily stored in the capacitor 75, and this electric power is supplied for an authentication operation described later (see FIG. 19).

  As shown in FIG. 20D, when the power switch 74 pressed by the operator is released, the switch body 54 is returned to the front by the urging force of the spring member 53. At this time, the rotating body 56 rotates around the shaft portion 55 so that the front tapered surface of the flange portion 56 a rides on the upper end portion of the engaging body 45, and after having passed over the upper end portion, is engaged with the engaging body 45. Return to possible original position.

  Next, as shown in FIG. 19, when the operator inputs a password using the numeric keypad 9, the controller 35 to which power is supplied from the temporarily stored capacitor 75 indicates that the input password is previously stored. It is determined whether or not it matches the registered authentication number. When the password is matched with the authentication number and authentication is permitted, the switch 33 between the generator 40 and the electromagnet 30 is turned on. Thus, by operating the power switch 74 (second operating means), it is possible to supply power to the control means 35 for authentication means using the coil spring 48 (elastic member). In addition, since the power for authentication means may be smaller than the power for rotating the rotating body 19 for unlocking which will be described later, the length of the coil spring 48 to be extended may be set relatively short. Furthermore, a primary battery may be disposed inside as a power supply unit for authentication means.

  Next, with reference to FIGS. 21A to 21E, a procedure when the operator performs an unlocking operation in the third embodiment will be described.

  First, as shown in FIG. 21A, the operating member 13 is positioned at a locking position where the engaging portion 18 is inserted into the receiving seat 17 of the fixture 1 and locked, and the operation gear 21. The operating pin 22 is positioned at the left end of the arc-shaped portion 23a of the operating hole 23 of the operating member 13, and the rotating body 19 restricts the moving operation of the operating member 13 with its notch 52 positioned at the upper position. The procedure when the unlocking operation is performed by the user will be described with the state as the initial state.

  As described above, when authentication is permitted by the authentication means, the control unit 35 controls the switch 33 of the electric circuit 5 to be in the ON state. Thereafter, the operator rotates the knob 38 in the clockwise direction.

  Next, as shown in FIG. 21 (b), when the knob 38 (operation means) is rotated clockwise by a predetermined angle by the operator, the engagement piece 36 of the operation gear 21 is moved to the engagement piece 34. The upper side is engaged. Thereafter, while the knob 38 is further rotated to a predetermined angle, the engaging piece 36 pushes down the engaged piece 34, and the rotational force of the operation gear 21 causes the engaged piece 34 and the bevel gears 42, 44 to move. The coil spring 48 for power generation is stretched according to the rotation of the rotary shaft 41, and the energy for the operator to rotate the knob 38 is temporarily stored as energy by the coil spring 48.

  During this time, the notch 52 of the rotating body 19 is in the upper position as shown in FIG. 21B, and the movement of the operating member 13 is restricted. That is, the rotating body 19 is maintained in the restricted state, and the operation member 13 is positioned at the locking position.

  Although not shown in particular, the tooth portion of the operation gear 21 is engaged with the tooth portion of the rotary damper gear, for example, and braking is performed so that the rotation of the operation gear 21 becomes a predetermined speed or less by the braking force of the rotary damper. It may be.

  Then, as shown in FIG. 21 (c), when the knob 38 is further rotated clockwise by a predetermined angle, the engagement state between the engagement piece 36 and the engagement piece 34 of the operation gear 21 is released. The Then, the extension of the coil spring 48 for power generation ends, the energy stored in the coil spring 48 is instantaneously released, the coil spring 48 starts to shrink due to the restoring force, and the rotating shaft 41 rotates counterclockwise, Power generation at 40 begins. Then, when the rotational speed of the rotating shaft 41 urged by the restoring force of the coil spring 48 becomes the fastest, an induced current having a peak as shown in FIG. The coil spring 48 constitutes an elastic member of the present invention. In the meantime, the operation member 13 is in the locked position.

  The electric power generated by the generator 40 is supplied to the electromagnet 30 disposed in the vicinity of the rotating body 19 via the switch 33 and the rectifier 36b of the branch line 32b, and the electromagnet 30 is temporarily magnetized to have a predetermined value. Generate a magnetic field.

  Then, the permanent magnet inside the rotator 19 is affected by the magnetic force, the rotator 19 is rotated, and the orientation of the rotator 19 is switched. That is, as shown in FIG. 21C, the cutout portion 52 of the rotating body 19 is moved to the lower position, and the restriction of the movement operation of the operation member 13 is released.

  Further, in the present embodiment, in the locking / unlocking operation, the knob spring 38 is rotated by a predetermined angle so that the coil spring 48 extends a certain length. Regardless of the operating condition (the force applied to the knob 38 or the rotational speed), a certain amount of energy is stored in the coil spring 48. And since it is made to generate electric power with the generator 40 only using the restoring force of the coil spring 48, the induced current which has a substantially constant peak arises irrespective of the operating condition of the knob | pick part 38 by a user. Therefore, the strength of the magnetic field generated by the electromagnet 30 is also substantially constant, and the rotating body 19 is rotated at a constant speed every time regardless of how the knob 38 is operated by the user.

  Further, the restricted state by the restriction part is a state in which the operation member 13 cannot pass through the predetermined operation path, and the restriction release state by the non-restriction part is a state in which the operation member 13 can pass through the predetermined operation path. That is, for example, the restriction release state is a state in which even if there is a restriction member in the operation path, the restriction member is pushed out by contacting the operation member 13 and the operation member 13 can pass through the operation path. There may be.

  Next, as shown in FIG. 21 (d), when the knob 38 is further rotated clockwise by a predetermined angle, the operation pin 22 of the operation gear 21 is moved to the linear portion 23 b of the operation hole 23 of the operation member 13. The moving member 13 is pushed to the right and moved while moving along. At this time, the operation member 13 is moved at a speed according to the operation of the knob 38 by the user.

  Although not particularly illustrated, if the tooth portion of the operation gear 21 is meshed with the tooth portion of the rotary damper, braking is applied so that the rotation speed of the operation gear 21 is reduced to a certain degree. Immediately after the engaged state with the engaged piece 34 is released, the resistance when rotating the operation gear 21 is not rapidly reduced. If the limiting means is configured like this rotary damper, the user continues to turn the knob 38 with excessive force or speed, and the operation member 13 rotates before the switching of the rotary body 19 is completed. Contact with the body 19 is avoided.

  When the operating member 13 reaches the unlocked position, the engaging portion 18 of the operating member 13 is detached from the receiving seat 17 of the fixture 1 and the drawer 2 can be opened.

  Furthermore, as shown in FIG. 21E, when the knob 38 is further rotated clockwise by a predetermined angle until the operation pin 22 comes into contact with the end of the operation hole, the operation according to the operation of the knob 38 is performed. The operating member 13 is further moved at the speed, and reaches the rightmost end of the range in which the operating member 13 is moved in this embodiment. Thereby, unlocking operation is complete | finished. During this time, the operating member 13 is located at the unlocked position, and the drawer 2 can be opened even before the operating member 13 reaches the rightmost end.

  When the unlocking operation is performed by the user, authentication is first performed by the authenticating means. However, if the user inputs a password with the numeric keypad 9 and the authentication is rejected, power generation in the electric circuit is performed. The switch 33 between the machine 40 and the electromagnet 30 is turned off. When the knob 38 is rotated by the user in this state, the operation gear 21 and the rotating shaft 41 are rotated, but current is prevented from flowing to the electromagnet 30 by the switch 33 in the OFF state and the rectifier 36a of the branch line 32a. Since no magnetic force is generated, the rotating body 19 is not rotated and the restricted state is maintained. Therefore, when the operating member 13 is moved in the right direction, the contact portion 15a comes into contact with the rotating body 19, so that the movement of the operating member 13 is restricted. That is, the state in which the operation member 13 remains in the locked position is maintained, and the engaging portion 18 of the operation member 13 is locked to the receiving seat 17 of the side plate 16 of the fixture. The person cannot open drawer 2.

  Next, the procedure at the time of locking the fixture 1 with a locking device is demonstrated. When the user performs the locking operation, the authentication means need not be operated. First, when the knob 38 in the unlocked state is rotated counterclockwise by the user, the operation member 13 in the unlocking position is pushed leftward by the operation pin 22 of the operation gear 21. Then, the engaging portion 18 of the operation member 13 is locked to the receiving seat 17 of the fixture. That is, the operation member 13 moves to the locking position.

  When the knob 38 is further rotated counterclockwise, the engaging piece 36 of the operation gear 21 is engaged with the lower side of the engaged piece 34. Then, the engaging piece 36 pushes up the engaged piece 34 to extend the coil spring 48, and energy is temporarily stored by the coil spring 48. At this time, the rotation directions of the operation gear 21 and the rotary shaft 41 are opposite to those in the unlocking operation described above.

  Thereafter, the engagement state between the engagement piece 36 and the engagement piece 34 is released, the energy stored in the coil spring 48 is instantaneously released, the coil spring 48 is contracted by the restoring force, and the rotating shaft 41 rotates clockwise. In the electric circuit of the third embodiment, the induced current having a peak as shown in FIG. 3 (b) is induced via the rectifier 36a of the branch line 32a. Flowing. And the electric current is supplied to the electromagnet 30, the electromagnet 30 is temporarily magnetized, and the magnetic field opposite to the time of the unlocking mentioned above generate | occur | produces. The rotating body 19 is rotated by this magnetic field, and the direction of the rotating body 19 is switched. That is, the cutout portion 52 of the rotating body 19 moves to the upper position and the movement operation of the operation member 13 is restricted, so that the movement of the operation member 13 in the locked position is restricted, and the drawer 2 is It becomes impossible to open.

  As described above, in the power generation apparatus according to the present embodiment, the rotating body 19 having the magnetic poles is changed in direction by the electromagnet magnetized along with the power generation by the generator 40, so that the control of the rotating body 19 can be easily performed and the operation member is restricted. Only by switching between the restriction part and the non-regulation part, the movement of the operation member can be reliably restricted or permitted. Moreover, the timing at which the rotating body 19 is switched can be easily separated from the mechanical movement of the knob 38, and the degree of control for switching the state of the rotating body 19 can be improved. In addition, since the power supplied from the generator 40 (power generation unit) that generates power by the operation of the knob 38 is used for the switching of the rotary body 19, it can be used without requiring external power supply. Locking and unlocking can be performed only by the operation of the knob 38 by a person.

  In addition, energy by the operation of the knob 38 is temporarily stored by the coil spring 48 (elastic member), and the energy is instantaneously released, so that the user does not operate the knob 38, The electric power necessary for switching the state of the rotating body 19 is stably supplied at a predetermined timing, so that the locking and unlocking can be surely performed, and a stable power generation amount can be obtained regardless of the operation condition of the operator. Can be secured.

  Further, when the authentication is permitted by the numeric keypad 9 (authentication means), the rotating body 19 can be operated, so that the numeric keypad 9 (authentication means) can be used as a key for the output operation.

  In addition, since the generator 40 that supplies power for performing the output operation also serves as a power supply unit and supplies power to the control unit 35 for authentication means, the number of components for supplying power is reduced. Can be simplified.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above-described embodiment, the switch 33 is provided on the branch line 32b of the electric wire 32, and when the user performs an unlocking operation, authentication by an authentication unit is required. However, the switch 33 is provided on the branch line 32b of the electric wire 32. In this case, a switch may be provided on the other branch line 32a so that authentication by the authentication means is required when the user performs a locking operation.

  Moreover, in the said Example, although the coil springs 25 and 48 are applied as an elastic member which stores energy temporarily, and mechanical energy is accumulate | stored in the coil springs 25 and 48, for example, as an energy storage means, electrical energy is stored. May be configured to accumulate.

  In the embodiment, the generators 68 and 40 are applied as the power generation unit. For example, the power generation unit includes a piezoelectric element and a movable member, and uses the movable member that is moved by the released energy.
