The position where the extended protrusion comes into contact with the receiving surface as the rotary shaft rotates in conjunction with the rotation shaft may be set so as to be sequentially away from the rotary shaft of the second transmission member. Good.

  Further, the operating force transmission mechanism portion is attached to a rotating shaft portion that rotates in conjunction with the posture change of the handle portion, and has an extending protrusion that extends outward in the radial direction of the rotating shaft portion. 1 transmission member and a receiving surface capable of abutting on the extension protrusion, receiving a rotating force of the first transmission member, rotating around a predetermined rotation axis, and A second transmission member that moves from the standby position toward the power storage position, and a groove is formed at the tip of the first-stage extension protrusion, and a pin is provided between the groove and the first-surface receiving surface. And the handle portion is disposed on a line that substantially passes through the rotation axis extension of the second transmission member in a state in which the handle portion is in the initial posture, and the handle portion is in the posture from the initial posture. The pin is disposed at a position crossing the receiving surface in a state where the rotating shaft portion rotates in conjunction with the change. Member or may be provided with a pin urging member pulling.

  The operating force transmission mechanism has a second transmission member that rotates around a predetermined rotation axis in conjunction with a change in the posture of the handle, and a pin-like member is provided on the force accumulation movable member. The second transmission member is formed with a pushing surface extending outward from a rotation axis thereof, and the pushing surface pushes the pin-shaped member with the rotation of the second transmission member to move the accumulated force. The member is moved from the standby position toward the power storage position, and when the power storage movable member reaches the power storage position, the pushing surface is retracted from the movement locus of the pin-shaped member, whereby the power storage is performed. The force movable member may be configured to be openable, and the distal end portion of the pushing surface may be formed in a shape inclined inward toward the distal end side.

  The authentication lock device is attached to a storage device having an openable / closable opening / closing portion and a pulling portion that is opened to change the posture from an initial posture to an open posture before the opening / closing portion is opened. And a force-accumulating movable member that is movably disposed between a standby position and a power-accumulating position, and biases the power-accumulating movable member from the power-accumulating position toward the standby position. The biasing member to be moved and the opening operation applied to the pulling portion are moved to move the force accumulation movable member from the standby position toward the force accumulation position, and the pulling portion reaches the opening posture from the initial posture. An operating force transmission mechanism that opens the force-accumulating movable member so that it can move toward the standby position at a midway position or a position that has reached the opening posture, and the force-accumulating force by the urging force of the urging member The movable member is in front of the accumulated power position. A power generation unit that receives power when moving to a standby position, generates a power, receives a power supply from the power generation unit, and switches the opening / closing unit from a closed state to an openable state; and supplies power from the power generation unit. Receiving authentication information about the user, determining whether or not the opening / closing part can be used based on the authentication information, and controlling the locking device to switch from the closed state to the openable state when it is determined that the user can use the information. And a control unit.

  According to this storage system, a power storage movable member that is movably disposed between a standby position and a power storage position, and a bias that biases the power storage movable member from the power storage position toward the standby position. In response to an opening operation applied to the biasing member and the pulling portion, the force accumulation movable member is moved from the standby position toward the force accumulation position, and the pulling portion is in the middle of reaching the opening posture from the initial posture. An operating force transmission mechanism that opens the force accumulation movable member and enables movement toward the standby position at the position or the position where the opening posture is reached. For this reason, when the handle portion is operated, the force accumulation movable member moves from the force accumulation position to the standby position by the urging force of the urging member. And a power generation part receives electric power of the accumulation-accumulation movable member which moves in this way, and can thereby make a lock device openable. For this reason, it is possible to generate larger electric power with the power generation unit provided in the storage device.

  Further, according to another storage system, the power accumulation movable member that is movably disposed between the standby position and the power accumulation position, and the power accumulation movable member is attached from the power accumulation position toward the standby position. In response to an urging member to be biased and an opening operation applied to the pulling portion, the force accumulation movable member is moved from the standby position toward the force accumulation position, and the pulling portion is changed from the initial posture to the opening posture. An operating force transmission mechanism that opens the force accumulation movable member and enables movement toward the standby position at a position in the middle of reaching or at a position at which the release posture is reached. For this reason, when the handle portion is operated, the force accumulation movable member moves from the force accumulation position to the standby position by the urging force of the urging member. And a power generation part receives electric power of the accumulation-accumulation movable member which moves in this way, and can make a lock device openable. For this reason, it is possible to generate larger electric power with the power generation unit provided in the storage device.

  Furthermore, the power generation unit includes a rotation transmission body and a power generation main body that generates power by the rotation of the rotation transmission body, and the power storage movable member moves on the way from the power storage position to the standby position. The rotation transmission body is engaged with the rotation transmission body to rotate the rotation transmission body, and the engagement with the rotation transmission body is released in a state where the rotation transmission body is positioned at the standby position so that the rotation transmission body is in a free rotation state. The power storage movable member rotates the rotation transmission body while moving from the power storage position to the standby position, and freely rotates the rotation transmission body in the state of reaching the standby position. For this reason, a rotation transmission body can be rotated for a longer period of time, and it can enable it to generate more electric power.

  Further, if the urging member is formed by connecting a plurality of strong and weak divided elastic members in series, the relatively weak divided elastic member is mainly elastically deformed at the initial stage of elastic deformation of the urging member. For this reason, the operating force can be reduced especially in the initial stage of operating the handle part.

  Further, as the rotary shaft portion rotates in conjunction with the posture change of the pulling portion from the initial posture toward the open posture, the position where the extending protrusion abuts the receiving surface is the first position. If the two transmission members are set so as to be gradually away from the rotation axis, the operating force of the handle can be gradually reduced.

  In addition, a concave groove is formed at the tip of the first projecting protrusion, and a pin-like member is disposed between the concave groove and the first receiving surface so as to be movable in the projecting direction of the projecting protrusion. In a state where the handle portion is in the initial posture, the handle portion is disposed on a line that substantially passes over the extension of the rotation axis of the second transmission member, and in conjunction with the posture change of the handle portion from the initial posture. When a pin urging member is provided to pull the pin-shaped member and is disposed at a position crossing the receiving surface in a state where the rotating shaft is rotated, the pin urging is performed in a state where the pulling portion is in an initial posture. The member does not apply a force for rotating the second transmission member. On the other hand, when the rotary shaft portion rotates in conjunction with the posture change from the initial posture toward the open posture, the pin urging member pulls the receiving surface together with the pressing pin-like member. Apply a rotating force. Thereby, a 2nd transmission member rotates easily and it can reduce the operating force of a handle part.

  Further, as the second transmission member rotates, the pushing surface pushes the pin-like member to move the force accumulation movable member from the standby position toward the energy accumulation position, and the force accumulation movable member When the force accumulation position is reached, the pushing surface is retracted from the movement locus of the pin-shaped member, and in the configuration in which the force accumulation movable member can be opened, the tip of the pushing surface is the tip side. By being formed in a shape that is inclined inwardly toward the head, the operating force can be reduced during the operation of the handle part.

  Further, according to the authentication lock device, the force accumulation movable member that is movably disposed between the standby position and the force accumulation position, and urges the force accumulation movable member from the force accumulation position toward the standby position. The biasing member to be moved and the opening operation applied to the pulling portion are moved to move the force accumulation movable member from the standby position toward the force accumulation position, and the pulling portion reaches the opening posture from the initial posture. And an operating force transmission mechanism that opens the force accumulation movable member so as to be movable toward the standby position at a midway position or a position that has reached the open posture. For this reason, when the handle portion is operated, the force accumulation movable member moves from the force accumulation position to the standby position by the urging force of the urging member. And a power generation part receives electric power of the accumulation-accumulation movable member which moves in this way, and can make a lock device openable. For this reason, it is possible to generate larger electric power with the power generation unit provided in the storage device.

Here, a plurality (three in this case) of power generation units 38 are provided, and each of the power generation units 38 receives the force from the power generation main body 39a having the rotation shaft portion 39b and the power accumulation movable member 28 and rotates. A gear portion 39 c is provided as a rotation transmission body for rotating the shaft portion 39. The power generation main body 39a is a rotating machine that converts a rotational force into electric power by an electromagnetic induction phenomenon or the like, such as a DC generator or an AC generator. The plurality of power generation main body portions 39a are attached and fixed to the inner surface of the other side plate 26 in a posture in which the rotation shaft portion 39b is disposed in a predetermined direction (here, the vertical direction). Further, each rotating shaft portion 39 b extends through the other side plate 26 to the side of the pair of power generation device mounting brackets 27. In addition, gear portions 39c are fixed to the tip portions of the respective rotation shaft portions 39b. When the power accumulation movable member 28 moves from the power accumulation position toward the standby position, each transmission claw 29c engages with the gear portion 39c and rotates the gear portion 39c in a predetermined direction. Yes. Further, at least in a state where the force accumulation movable member 28 is located at the standby position, here, the second movable member 29b is separated from the arrangement direction of the rotary shaft portions 39b while the force accumulation movable member 28 is moving to the standby position. As a result, the engagement between each transmission claw 29c and each gear portion 39c is released, and then each gear portion 39c rotates freely. Thus, each power generation main body 38a generates power by rotating each gear 39c.

  The operating force transmission mechanism 32 receives the opening operation applied to the pulling portion 12a and moves the power accumulation movable member 28 from the standby position toward the power accumulation position, and the pulling portion 12a reaches the open posture from the initial posture. Or the position that has reached the open position (here, the position that has reached the midway position) is configured to open the force accumulation movable member 28 so as to be movable toward the standby position.

  More specifically, the operating force transmission mechanism 32 includes a first transmission member 34 and a second transmission member 36.

  The first transmission member 34 is attached and fixed to the rotating shaft portion 17c that rotates in conjunction with the posture change of the pulling portion 12a, and an extending protrusion 35 that extends outward in the radial direction of the rotating shaft portion 12a. Have. More specifically, the extension protrusion 35 is formed in an elongated plate shape, and one side portion of the tip portion thereof is formed as a straight portion 35a extending along the radial direction of the rotary shaft portion 12a. The other side part of the part is formed in an inclined part 35b that gradually narrows the tip part toward the tip side. The first transmission member 34 is fixed in a posture in which the extending protrusion 35 is disposed downward between the pair of power generation device mounting brackets 27 in a state where the handle portion 12a is in the initial posture. And if the rotating shaft part 17c rotates in connection with changing the attitude | position toward the open attitude | position to the handle part 12a, the extension protrusion 35 will be rotated in the same direction as the handle part 12a in response to it.

  The second transmission member 36 is formed as a cam-like member having a receiving surface 36a and a pin pushing portion 36b. More specifically, the second transmission member 36 is swingably supported via a shaft portion 36 c at an upper portion between the pair of power generation device mounting brackets 27 and below the first transmission member 34. The receiving surface 36a is formed in a substantially flat surface, and is disposed to face the straight portion 35a of the extending protrusion 35 in a state where the handle portion 12a is in the initial posture. Then, when the first transmission member 34 rotates in this state, the receiving surface 36a of the extending protrusion 35 is pressed, and the second transmission member 36 rotates around the shaft portion 36c under the pressing force (FIG. 8). And a clockwise rotation in FIG. 9). As a result, the second transmission member 36 also rotates around a predetermined rotation axis in conjunction with the posture change of the handle portion 12a.

  The position where the extended protrusion 35 abuts on the receiving surface 36a is changed as the extended protrusion 35 pushes the receiving surface 36a (that is, the posture of the pulling portion 12a is changed from the initial position toward the open position). Accordingly, the distance from the rotation axis of the shaft portion 36c is gradually increased. As a result, as the second transmission member 36 is rotated (that is, as the handle portion 12a is opened), the force point of rotation of the second transmission member 36 gradually becomes far from the fulcrum (shaft portion 36c) and is relatively light. The second transmission member 36 can be rotated by force.

  Further, a groove 36d is formed at the tip of the pin pushing portion 36b, and the outer (upper) end of the first movable member 29a is disposed between the grooves 36d and inserted therethrough. The pin-shaped member 29p is disposed in contact with the pushing surface 36e on one side of the pin pushing portion 36b. Here, the pushing surface 36e is a substantially flat surface extending outward from the shaft portion 36c. Then, when the second transmission member 36 is rotated by the extension protrusion 35 receiving a force pushing the receiving surface 36a, the pin pushing portion 36b is pushed and moved to lift the pin-like member 29p upward. The force accumulation movable member 28 is moved from the standby position toward the force accumulation position (see FIG. 9). When the second transmission member 36 further rotates and the force accumulation movable member 28 moves to the force accumulation position, the pushing surface 36e of the pin pushing portion 36b retracts from the movement locus of the pin-like member 29p (one point in FIG. 9). (See chain line). Then, the engagement between the pin-shaped member 29p and the pin pushing portion 36b is released, and the force accumulation movable member 28 is released to move from the force accumulation position toward the standby position. Note that the engagement between the pin-shaped member 29p and the pin pushing portion 36b is released when the pulling portion 12a reaches the midway posture, but it may be at a position before it.

  A coil spring 36s as an urging member is disposed in an extended state between the pin pushing portion 36b and the pair of power generation device mounting brackets 27 and below the pin pushing portion 36b. The coil spring 36s urges the pin pushing portion 36b downward, and has a role of returning the second transmission member 36 to the initial posture when the operating force of the handle portion 12a is released. Yes.

  A series of operations of the power generation device 22 will be described. First, when the handle portion 12a is operated, the rotary shaft portion 17c rotates. Thereby, the 1st transmission member 34 rotates and the extension protrusion 35 presses the receiving surface 36a of the 2nd transmission member 36. As shown in FIG. Thereby, the 2nd transmission member 36 rotates, the pin pushing part 36b lifts the pin-shaped member 29p upward, and moves the force accumulation movable member 28 to the force accumulation movable member 28 (refer FIG. 9). When the handle portion 12a is further operated to further rotate the second transmission member 36, the pin pushing portion 36b and the pin member 29p are disengaged (see the one-dot chain line in FIG. 9).

  Then, due to the urging force of the coil spring 30, the force accumulation movable member 28 is pulled back from the force accumulation position toward the standby position with a relatively strong force and at a relatively high speed. In the middle of this, each transmission claw 29c of the second movable member 29b rotates the gear portion 39c. Then, in a state where the force accumulation movable member 28 reaches the standby position, the engagement between each transmission claw 26c and each gear portion 39c is released, and each gear portion 39c continues to rotate freely for a while due to inertia. The power generation main body 38a generates power by the rotation of each gear 39c. This generated power is supplied to the lock device 50 and the control unit 40.

  According to the power generation device 22, when the handle portion 12a is operated, the force accumulation movable member 28 is moved from the force accumulation position to the standby position with a relatively strong force and relatively high speed by the biasing force of the coil spring 30. The power generation unit 39a generates power by receiving the force of the power accumulation movable member 28 that moves in this manner, and the control unit 40 and the lock device 50 are operated by the generated power. In this way, since the power generation unit 39a generates power by receiving the force of the accumulating movable member 28 that moves at a relatively strong force and at a relatively high speed, larger power can be generated. In particular, there is a great merit in that a constant generated power in the power generation unit 39a can be expected regardless of the operation speed of the pulling unit 12a.

  Moreover, when the accumulating movable member 28 reaches the standby position, the engagement between each transmission claw 29c and the gear portion 39c is released, and the gear portion 39c freely rotates due to inertia. It can be expected to generate power at the part 39a. Therefore, it is possible to generate a larger amount of power by rotating the gear portion 39c for a longer period of time.

  Further, as the pulling portion 12a changes its posture from the initial posture toward the open posture, the position where the extended protrusion 35 abuts on the receiving surface 36a is gradually distant from the shaft portion 36c of the second transmission member 36. Since it is set, the second transmission member 36 can be gradually rotated with a relatively light force. For this reason, the operating force of the handle part 12a can be gradually reduced from the initial posture toward the open posture.

<4-1a. First Modification of Power Generation Device>
A first modification of the power generator 22 will be described. FIG. 10 is a diagram showing a first modification. Only the difference from the above will be described. In the first modification, instead of the coil spring 30, a connection coil spring 130 in which a plurality of split coil springs 130a and 130b as strong and weak split elastic members are connected in series is used. . And the said connection coil spring 130 is attached between the intermediate part of the 2nd movable member 29b and the lower end part of a pair of electric power generating apparatus attachment bracket 27 in the expansion | extension state. Here, the fact that the divided elastic members are strong and weak means that the elastic moduli are different, that is, the spring constants of the divided coil springs 130a and 130b are different.

  According to the first modification, at the initial stage of extension of the coupling coil spring 130, the relatively weaker split coil spring 130b is mainly extended and deformed. Then, the relatively strong split coil spring 130a gradually expands and deforms from the middle. For this reason, the operating force can be reduced especially in the initial stage of operating the handle part 12a. On the other hand, in the state in which the pulling portion 12a is changed to the halfway posture toward the open posture, the relatively strong split coil spring 130a is also extended and deformed relatively large. It can be moved from the accumulation position toward the initial position. Therefore, it is possible to achieve both the reduction of the operating force of the handle portion 12a and the generation of large electric power.

  In addition, in this case, as described above, as the handle portion 12a changes its posture from the initial posture toward the open posture, the position at which the extended projection 35 abuts on the receiving surface 36a is the position of the second transmission member 36. By combining with the configuration set so as to be gradually away from the shaft portion 36c, it is possible to reduce the operating force over almost the entire range in which the handle portion 12a is operated. That is, in the initial operation stage of the pulling portion 12a, the operating force can be reduced by mainly extending and deforming the relatively strong split coil spring 130a. Then, during the operation of the pulling portion 12a, the position where the extended projection 35 abuts against the receiving surface 36a is sequentially moved away from the shaft portion 36c of the second transmission member 36, so that the second transmission can be performed with a relatively light force. The member 36 can be rotated to reduce the operating force of the handle portion 12a. Therefore, it is possible to reduce the operating force over almost the entire area where the handle portion 12a is operated.

  Note that three or more elastic members may be combined according to the required characteristics.

<4-1b. First Modification of Power Generation Device>
A second modification of the power generator 22 will be described. FIG. 11 is a diagram showing a second modification. Only the difference from the above will be described. In the second modification, instead of the second transmission member 36, the distal end portion of the pushing surface 36e of the second transmission member 36 is directed toward the distal end side. The 2nd transmission member 136 formed in the shape which inclines in direction is used. More specifically, the distal end portion of the pushing surface 36e of the second transmission member 136 is rounded to form a curved portion 136r.

  In the second modified example, since the distal end portion of the pushing surface 36e is formed in the curved portion 136r, the pin-shaped member 29p is moved in the predetermined posture change range θ in which the curved portion 136r contacts the pin-shaped member 29p. The amount L1 to be lifted can be made relatively small, and the pin-shaped member 29p can be lifted with a larger force. That is, the operating force applied to the handle part 12a may be relatively weak.

  On the other hand, as shown in FIG. 12, when the pushing surface 36e is flat, the amount L2 for lifting the pin-like member 29p is relatively large in the predetermined posture change range θ, which is larger than the above case. The force for lifting the pin-shaped member 29p is relatively weak, and it is necessary to relatively increase the operating force applied to the handle portion 12a.

  Therefore, in the second modification, the operation force can be reduced in a predetermined posture change range θ in which the bending portion 136r contacts the pin-shaped member 29p, that is, in the middle stage of operating the pulling portion 12a.

<4-1c. Third Modification of Power Generation Device>
A third modification of the power generator 22 will be described. FIG. 13 is a diagram showing a third modification, and FIG. 14 is a diagram showing the operation of the third modification. Only the difference from the above will be described. In the third modified example, the following first transmission member 134 is used instead of the first transmission member 34.

  The first transmission member 134 has the same configuration as the first transmission member 34 and is fixed to the rotating shaft portion 17c. Further, the second transmission member 134 has an extending protrusion 135 that extends outward in the radial direction of the rotating shaft portion 17c. Note that the extension protrusion 135 itself extends to a close position avoiding the second transmission member 36 to the side, and does not interfere with the receiving surface 36 a of the second transmission member 36. In addition, a substantially U-shaped groove 135g that opens to the distal end side is formed at the distal end of the extending protrusion 135, and a pin-shaped member 135p is provided in a projecting manner in the substantially U-shaped groove 135g. ing. The pin-shaped member 135p protrudes so as to come into contact with the receiving surface 36a of the second transmission member 36. The pin-shaped member 135p is disposed and supported in a space surrounded by the substantially U-shaped groove 135g and the receiving surface 36a when viewed from the side.

  In addition, a coil spring 135s as a pin urging member is attached in an extended state between the distal end portion of the pin-like member 135p and a predetermined fixing portion of the power generation device attachment bracket 27. The predetermined fixing portion of the power generation device mounting bracket 27 is set so as to satisfy the following positional relationship. That is, the coil spring 135s is disposed on a line that substantially adds the extension of the shaft portion 36c of the second transmission member 36 with the handle portion 12a in the initial posture (see FIG. 13), and the handle portion 12a is arranged so as to be positioned on a line crossing the receiving surface 36a in a state in which the posture is changed from the initial posture toward the open posture (see FIG. 14).

  In a state where the pulling portion 12a is in the initial posture, the coil spring 135s pulls the pin-shaped member 29p on an extension passing through the rotating shaft portion 17c of the second transmission member 36. At this time, the urging force of the coil spring 135s is received by the rotating shaft portion 17c, and no force that rotates the first transmission member 34 and the second transmission member 36 acts. Then, when the posture of the handle portion 12a is changed, the coil spring 135s is displaced from the extended line passing through the rotating shaft portion 17c and is disposed on a line crossing the receiving surface 36a. Then, the urging force of the coil spring 135s acts as a force for pulling the pin-shaped member 29p toward the receiving surface 36a, and also acts as a force for rotating the second transmission member 36. Thereby, the 2nd transmission member 36 rotates easily and the operating force of the handle part 12a can be reduced.

<4-2. Locking device>
The lock device 50 will be described. 15 is a side view showing the lock device, FIG. 16 is a view showing the operation of the lock device, FIG. 17 is a rear view of the lock device, and FIG. 18 is a plan view of the lock device.

  The lock device 50 is configured to be able to switch the door 12 from an open state to an openable state upon receiving the power supply from the power generation unit 38. Here, the first locking device 50 receives the power supply from the power generation unit 38. A rotation lock portion 52 that restricts or allows the rotation of the rotation shaft portion 17c during rotation from the rotation posture to the second rotation posture is provided.

  More specifically, the rotation lock unit 52 includes a rotation regulating member 54, a coil spring 56 as a rotation regulating member urging member, and an unlocking drive unit 60.

  The rotation restricting member 54 is a long plate-like member, and an intermediate portion in the longitudinal direction thereof is provided at a distal end portion of the support portion 26a that extends outward from the lower position of the rotation shaft portion 17c of the side plate 26. It is supported so as to be swingable through the shaft portion 26b.

  A rotation restricting piece 55 is attached to the rotating shaft portion 17c. The rotation restricting pieces 55 are a pair of long plate members, and are fixed to the rotating shaft portion 17c so as not to rotate relative to each other on both sides of the side plate 26, respectively. The pair of rotation restricting pieces 55 are formed so as to extend from the rotating shaft portion 17c to the outside of the side plate 26, and a pin-like member 55p is inserted and fixed at the tip portion thereof. In addition, the rotation regulation piece 55 may be single.

  A concave portion 54a is formed on one side of the upper end portion of the rotation restricting member 54, and an extended restricting piece 54b is formed to protrude from the upper end portion of the concave portion 54a.

  When the rotation shaft portion 17c tries to rotate at the rotation restriction position in which the upper end portion of the rotation restriction member 54 is swung away from the rotation shaft portion 17c, the pin-like member 55p at the tip of the rotation restriction piece 55 is moved. The rotation of the rotary shaft portion 17c is restricted by contacting the extension restricting piece 54b (see the two-dot chain line in FIG. 15). On the other hand, when the rotation shaft portion 17c tries to rotate at the rotation allowable position in which the upper end portion of the rotation restriction member 54 is swung in the direction approaching the rotation shaft portion 17c, the pin-like member 55p at the tip of the rotation restriction piece 55 is Since it passes outside the extension regulating piece 54b, the rotation of the rotating shaft portion 17c is allowed (see the two-dot chain line in FIG. 16). Even in this state, when the pin-like member 55p at the tip of the rotation restricting piece 55 comes into contact with the recess 54a, further rotation of the rotating shaft portion 17c is restricted.

  The coil spring 56 is configured to urge the rotation restricting member 54 toward the rotation restricting position. Here, a coil spring 56 is disposed in a compressed state between the lower portion of the rotation restricting member 54 and the side portion of the side plate 26, and the rotation restricting member 54 is brought into the rotation restricting position by the urging force of the coil spring 56 in the extending direction. It is energized towards.

  The unlocking drive unit 60 is configured to suck and hold the rotation restricting member in the rotation restricting posture in a non-energized state and cancel the attracting force when energized from the power generation unit 38.

  Here, the unlocking drive unit 60 is configured as a self-holding (or self-adsorptive) type plunger, and has a substantially U-shaped yoke 62 having a magnet 62 a and coils provided at both ends of the yoke 62. 63 and a substantially U-shaped movable piece 64. The yoke 62 is fixed to one side portion of the side plate 26, and the movable piece 64 is supported by the rotation restricting member 54 via the shaft portion 64a so that the posture can be changed.

  In a normal state where no current flows through the coil 63, the movable piece 64 is attracted and held on the yoke 62 by the magnetic force of the magnet 62a. Thereby, the rotation restricting member 54 is held in a state where the posture is changed to the rotation restricting position.

  In this state, when an open circuit voltage such as a pulse wave from the power generation unit 38 is applied, a magnetic flux that cancels the magnetic flux of the magnet 62a is generated by the coil 63, and the attracting force of the movable piece 64 is canceled. It becomes possible to separate from 62. Then, the posture of the rotation restricting member 54 is changed to the rotation allowable position by the urging force of the coil spring 56.

  Further, a rotation restricting member pressing piece 66 is provided on the rotating shaft portion 17c. The rotation restricting member pressing piece 66 is a member that changes the posture of the rotation restricting member 54 toward the rotation restricting position when the rotating shaft portion 17c rotates back from the second rotation posture toward the first rotation posture.

  That is, on the inner surface side of the side plate 26, the rotation restricting member pressing piece 66 is fixed to the rotating shaft portion 17c so as not to be relatively rotatable. The rotation restricting member pressing piece 66 extends between the side plate 26 and the rotation restricting member pressing piece 66 when viewed from the side. Further, a pin-like member 66 p protrudes from the tip of the rotation restricting member pressing piece 66.

  When the rotary shaft portion 17c rotates back from the second rotation posture to the first rotation posture, the pin-shaped member 66p comes into contact with one side portion of the rotation restricting member pressing piece 66 and resists the biasing force of the coil spring 56. Then, the posture of the rotation restricting member 54 is changed toward the rotation restricting position.

  The overall operation of the lock device 50 will be described. That is, the pulling part 12a is opened from the initial posture to the open posture. At this time, the rotating shaft portion 17c rotates together with the pulling portion 12a until the pulling portion 12a changes its posture to an intermediate posture.

  When the authentication result is unavailable, the rotation restricting member 54 restricts the rotation of the rotating shaft portion 17c, and only the handle portion 12a rotates. Accordingly, the authentication lock device 20 is maintained in the locked state, that is, the door 12 is closed.

  On the other hand, when the authentication result is available, the coil 63 is energized to release the attracted state of the movable piece 64, the rotation restricting member 54 changes its posture to the rotation allowable position, and the authentication lock device 20 enters the unlocked state. Become. As a result, the rotating shaft portion 17c can continue to rotate, and the door 12 can be opened.

  According to the lock device 50, when the handle portion 12a is operated, the rotating shaft portion 17c rotates at least halfway, so that the power generation unit 38 can generate power by the rotation of the rotating shaft portion 17c. Then, the rotation lock unit 52 and the control unit 40 can be operated by receiving power supply from the power generation unit 38. Similarly, upon receiving power supply from the power generation unit 38, the rotation of the rotary shaft portion 17c is regulated or allowed during the rotation from the first rotation posture to the second rotation posture, and the door 12 is maintained in the open / closed state. The switching operation to 12 openable states can be performed. For this reason, in accordance with the operation of the handle part 12a, it is possible to achieve both the power generation by the rotating shaft part 17c, the maintenance of the closed state of the door 12 and the switching operation to the openable state of the door 12 by the rotating shaft part 17c.

  Further, the handle portion 12a is rotatably connected to the rotary shaft portion 17c, and the rotary shaft portion 17c is changed to the first position as the handle portion 12a is changed from the initial posture toward the open posture. The handle portion 12a and the rotary shaft portion 17c are rotated so that only the handle portion 12a can be rotated when the rotary shaft portion 17c is rotated by the rotation lock portion 52 while rotating from the rotary posture to the second rotary posture. Therefore, even when the rotation of the rotary shaft portion 17c is restricted, the posture of the handle portion 12a can be changed to the open posture. For this reason, the operativity of the handle part 12a can be made favorable.

  Further, since the rotation restricting member 54 is sucked and held in a rotation restricting posture in a non-energized state, and is provided with an unlocking drive unit 60 that cancels the attracting force when energized from the power generation unit 38, the normal state (standby) In the state), the rotation restricting member 54 can be kept in the rotation restricting posture without consuming electric power. And the energization from the power generation unit 38 cancels the attracting force, and the posture of the rotation restricting member 54 can be changed to the rotation allowable posture. Therefore, power consumption can be reduced.

  Furthermore, when changing the posture so that the pulling portion 12a is returned to the initial posture, the rotation restricting member 54 is brought into contact with the rotation restricting member 54 by bringing the pin-like member 66p at the tip of the rotation restricting member pressing piece 66 into contact with the rotation restricting member 54. The posture can be changed toward the rotation restriction position to return to the locked state.

<4-3. Control unit>
As shown in FIG. 5, the control unit 40 is activated upon receiving power supply from the power generation unit 38, acquires authentication information about the user, and based on the authentication information, whether or not the door 12 to which the self is attached can be used. If it is determined that it can be used, the lock device 50 is driven and switched to the unlocked state.

  More specifically, the control unit 40 is a general microcomputer including a CPU, a ROM, a RAM, and the like, and all the arithmetic operations are executed by a software program stored in advance. The control unit 40 is activated when power is supplied from the power generation unit 38, and functions as the authentication control unit 40a and the lock control unit 40b by the power.

  In the authentication control unit 40a, an ID list that can use the door 12 to which the self is attached is registered in its own memory. Then, the authentication control unit 40a performs wireless communication with the ID card 18 through the antenna 40c upon activation, and whether or not the user possessing the ID card 18 can use the door 12 to which the user is attached. Authentication operation is performed.

  Here, the ID card 18 stores a unique ID (authentication information) in its own memory and performs wireless communication with the authentication control unit 40a in response to a request from the authentication control unit 40a. The information is wirelessly transmitted to the authentication control unit 40a. The ID card 18 is given to the user of the system, and the user operates the user to hold the ID card 18 and pull the handle portion 12a from the initial posture toward the operation posture.

  The lock control unit 40b drives and controls the lock device 50 by turning on and off the switching element 42 based on the authentication result of the authentication control unit 40a.

  FIG. 19 is a flowchart showing the operation of this control unit.

  As shown in the figure, when the power generation unit 38 generates power, the control unit 40 is activated upon receiving power supply from the power generation unit 38, as shown in step S1, and proceeds to step S2.

  In step S2, the authentication control unit 40a determines whether the wireless communication is successful. Here, if the user does not have the ID card 18, wireless communication is not established, and the process is terminated. On the other hand, if the user has the ID card 18, wireless communication is established with the ID card 18, and the process proceeds to step S3.

  In step S3, an ID request command is given to the ID card 18 through wireless communication. And when ID is not registered into ID card 18, ID cannot be acquired and processing is ended. On the other hand, if the ID can be acquired from the ID card 18, the process proceeds to step S4.

  In step S4, authentication is performed based on the ID of the ID card 18 acquired through wireless communication and the available ID list registered in its own memory. As a result of the authentication, if it is determined to be unacceptable (unusable), the process is terminated. On the other hand, if it is determined to be acceptable (available), the process proceeds to step S5, and an ON signal is given to the switching element 42. As a result, the switching element 42 is turned on, a drive current is applied to the lock device 50, the lock device 50 is unlocked (unlocking operation), and the user can use the corresponding door 12 or the like. Become.

  After performing the unlocking operation in step S5, in step S6, the authentication control unit 40a wirelessly communicates the user ID to the outside together with a code for identifying the door 12 and the like. This wireless communication is received by a management computer 80 provided outside. Thereby, the control part 40 complete | finishes a process.

  The management computer 80 communicates with the plurality of control units 40 to generate and update a table in which the user ID, the identification code of the user's door 12 and the like are associated with the usage time, and the like. It is stored as a usage history of this system.

<5. Explanation of overall operation>
The overall operation of this system will be described.

  First, the user possesses the ID card 18 assigned to the user and pulls the handle portion 12a to change the posture from the initial posture toward the operation posture.

  When the operation of the handle part 12a is started, the power generation unit 38 of the power generation device 22 generates power. Then, in the initial section in which the pulling unit 12a or the like changes its posture from the initial posture to the midway posture, the control unit 40 is activated upon receiving power supply and executes the authentication operation.

  If the authentication result in the control unit 40 is not available, the lock state of the lock device 50 is maintained in the middle operation period (intermediate posture) of the handle portion 12a, the actual lock by the latch mechanism 17b is maintained, and the door 12 or the like. Can't be opened.

  On the other hand, if the authentication result in the control unit 40 is available, the locking device 50 operates and the rotation lock unit 52 switches from the locked state to the unlocked state during the middle operation period (intermediate posture) of the handle part 12a. To do. Thereafter, the actual lock by the latch mechanism 17b is released and the door 12 and the like can be opened in the final period after starting the operation of the handle portion 12a and the like (from the midway posture to the open posture). At the same time, history data is transmitted from the control unit 40 to the management computer 80.

  When the use is finished, the user closes the door 12 and the like. At this time, as described above, the latch mechanism 17b is in a locked state that keeps the door 12 and the like closed regardless of the operation status of the power generation unit 38 and the lock device 50.

  This storage system has an advantage that external wiring for power supply can be eliminated.

  In addition, the power generation unit 38 generates power by operating the pulling unit 12a, etc., and then the control unit 40 is activated by receiving power supply from the power generation unit 38, acquires an ID related to the user, and can be used based on the ID. When it is determined that the lock device 50 can be used, the lock device 50 is driven and controlled so that the lock device 50 is switched to the non-lock state. In addition, there is also an advantage that a place where use authority is available can be used simply by opening the handle part 12a and the like.

  In addition, since ID acquisition related to the user is performed by wireless communication with the ID card 18, the user can open the handle part 12 a and the like while holding the ID card 18, thereby simplifying the storage location with the usage authority. Available to:

  Moreover, since only the control part 40 corresponding to what actually received operation of the handle part 12a etc. performs operation | movement, the possibility that other unrelated control part 40 malfunctions can also be avoided.

<6. Modification>
In the above embodiment, the example in which the control unit 40 incorporated in the authentication lock device 20 executes the function as the authentication control unit 40a and the lock control unit 40b has been described. However, the function as the authentication control unit 40a is an external control. It may be realized by an external controller as means.

  In this case, the external controller performs an authentication operation by performing wireless communication with the ID card 18 existing in the vicinity of the device in response to a wireless command from a device in which the authentication function is omitted in the authentication lock device 20, and the authentication is performed. The result may be returned to the device that gave the radio command. Note that the position specifying technique using three-point surveying can be applied to specify the position of the ID card 18 or the like by the external controller.

  That is, the function as the authentication control unit that performs the authentication operation does not necessarily have to be provided in the authentication lock device 20, and the means for executing the function is an actual power generation using the power generation in the authentication lock device 20 as a power source. There is no need to do any processing. In short, the control means inside or outside of the authentication lock device 20 performs the authentication operation due to the operation on the handle portion 12a and the like, and the authentication lock device 20 inside the authentication lock device 20 is driven and controlled by the internal generated power. Any configuration that switches from the locked state to the unlocked state may be used.

  Further, the authentication lock device 20 may be distributed as a device different from the cabinet 10 and retrofitted to the existing cabinet 10.

  Further, the authentication is not necessarily performed by acquiring the ID of the ID card 18 given to each user. For example, the user's face or retina present near the authentication lock device 20 may be authenticated. Further, an authentication device such as a fingerprint may be incorporated in the handle portion 12a or the like. In short, various configurations that acquire and authenticate information unique to each person can also be employed.
