JP 2010-167006 A JP 2009-052298 A JP2015-187345A

Although the cabinet provided with the electronic lock like patent document 3 can improve security with an electronic lock, since the electronic lock for the number of drawers is needed, manufacturing cost will increase.
As a solution, it is conceivable to combine one drawer with a battery-type electronic lock with an all-lock device that can lock a plurality of drawers collectively.

However, when combined with the all-lock device as in Patent Document 1 as a single drawer having a battery-type electronic lock, the interlock mechanism has a large mass, and the first block body (38) to the second block body ( 40) Since there is a mechanical loss when power is transmitted from the second block body (40) to the left and right third block bodies (42, 42), the operating force required to drive the interlocking mechanism increases.
Therefore, in a configuration in which a drawer including a battery-type electronic lock is combined with the all-lock device as in Patent Document 1, power saving is achieved so as to reduce the power consumption of the actuator of the battery-type electronic lock. From this perspective, there is room for improvement.

In addition, when a drawer having a battery-type electronic lock is combined with the all-lock device as in Patent Document 2, the drawers (22a, 22a) of the drawers (22, 22) adjacent vertically are spanned. The movement of the upper and lower operating parts (12, 12) is linked by the constructed linkage mechanism (B). Since the linkage mechanism (B) is incorporated in each movable drawer (22), the drawer ( 22) and the vertical drawers (22, 22,...) May be displaced in the front-rear direction due to backlash between the play portions of the cabinet body (housing 21) and dimensional errors. If there is such a positional shift, the operation of interlocking the movements of the upper and lower operating parts (12, 12) by the interlocking mechanism (B) may be uncertain.
Therefore, from the viewpoint of improving the reliability of the operation for making the all-locked state in which a plurality of drawers are collectively locked and / or the operation for making the unlocked state in which any of the drawers can be withdrawn, it is improved. There is room.

  Accordingly, the present invention provides an all-lock device that can lock a plurality of upper and lower drawers in a lump used in a cabinet having a plurality of upper and lower drawers with a single drawer having an electronic lock.

<Embodiment 1>
The cabinet C shown in the perspective view of FIG. 1 includes the drawer all-lock device A1 in the cabinet according to Embodiment 1 of the present invention, and includes a cabinet body 10 including left and right side plates 12, 13, a top plate 14 and a back plate 15. And three upper and lower drawers 11A, 11B, and 11C housed in the cabinet body 10.
The drawers 11 </ b> A, 11 </ b> B, 11 </ b> C are provided with a handle 9,... On the end panel F, and the uppermost drawer 11 </ b> A is provided with a battery-powered electronic lock B having an authentication part P adjacent to the handle 9.
The cabinet body 10 includes left and right lifting bodies E1, E2, E3, and E4 supported so as to be movable up and down inside the left and right side plates 12 and 13, and the left and right lock bodies 5 and 5 are in the uppermost position as shown in FIG. In a state where the lifting operations of the left and right lifting bodies E1, E1 are prevented, the drawers 11A, 11B, 11C are locked together, so that the drawers 11A, 11B, 11C cannot be pulled out.
In addition, the structure which provided only the lock body 5 corresponding to the raising / lowering bodies E1-E4 by providing the raising / lowering bodies E1-E4 only in the inner side of the right and left side plates 12 and 13 may be sufficient.

As shown in the perspective view of FIG. 1 and the enlarged perspective view of the main part of FIGS. 2 (a) and 2 (b), the cabinet body 10 is rotated about the left and right axis above the left and right lifting bodies E1 and E1. The left and right lock bodies 5 and 5 that move, the connection rod 4 that connects the left and right lock bodies 5 and 5, and the interlocking member D1 that includes the gear 3 fixed to the center in the left and right direction of the connection rod 4. Prepare.
Further, the cabinet body 10 includes an actuator M1 that operates in the unlocking UL when the authentication of the electronic lock B is successful and drives the interlocking member D1.
The actuator M1 is, for example, a plunger-type solenoid that includes a return spring that is an urging means and reciprocates linearly in the front-rear direction, and the tooth portion 2 of the operating body 1A that operates integrally with the plunger meshes with the gear 3.
With such a rack and pinion comprising the tooth portion 2 and the gear 3, power transmission can be reliably performed with a light force.

When the electronic lock B is locked L, the interlocking member D1 of the all lock device A1 is in the state shown in FIG. That is, with the gear 3 fixed to the connecting rod 4 meshing with the tooth portion 2 of the operating body 1A of the actuator M1, the lock bodies 5 and 5 fixed to the left and right end portions of the connecting rod 4 hang downward. The raising operation of the left and right lifting bodies E1, E1 is prevented.
As a result, the all lock device A1 is in an all lock state in which the drawers 11A, 11B, and 11C are locked together.

The interlocking member D1 of the all-lock device A1 is in the state shown in FIG. 2 (b) when the electronic lock B is successfully authenticated at the time of unlocking UL. That is, since the actuator M1 is driven and the plunger is sucked forward, the operating body 1A moves forward from the position of FIG. 2A to the position of FIG. 2B as indicated by the arrow in FIG. Drawn in. Since the gear 3 meshed with the tooth portion 2 of the operating body 1A is rotated, the connecting rod 4 is also rotated, and the left and right lock bodies 5, 5 having the connecting rod 4 as a rotation axis are rotated rearward.
Thereby, all lock device A1 will be in the lock release state in which right and left raising and lowering bodies E1 and E1 can raise.

Next, the details of the operation of the drawer all lock device A1 in the cabinet according to the first embodiment of the present invention will be described mainly with reference to schematic views of right side surfaces of the vertical cross sections of FIGS.
In the locked state L of the electronic lock B in which the drawer shown in FIGS. 2A and 3 is closed, the lock body 5 hangs downward to prevent the lifting body E1 from being lifted, so that the all-lock state is established.
In this state, since the energizing terminal 16A on the drawer 11A side is pressed against the energizing terminal 16B on the cabinet body 10 side by the compression coil spring 18, the cable 17A, energizing terminal 16A, energizing terminal 16B from the battery of the electronic lock B are used. In addition, electric power can be supplied to the actuator M1 through the cable 17B.
Specifically, a current-carrying terminal 16A is provided at the upper rear of the end panel F of the uppermost drawer 11A among the plurality of drawers, and is opposed to the current-carrying terminal 16A of the drawer 11A on the upper part of the cabinet body 10 (front surface of the top plate 14). An energizing terminal 16B is provided. Thereby, when the uppermost drawer 11A is closed, the energizing terminal 16A of the drawer 11A comes into contact with the energizing terminal 16B of the cabinet body 10.

  When the electronic lock B shown in FIGS. 2B and 4 has been successfully authenticated, the actuator M1 is unlocked from the battery through the cable 17A, the energizing terminal 16A, the energizing terminal 16B, and the cable 17B, as indicated by the arrows in the figure. Electric power is supplied to the actuator M1, and the actuator M1 is driven. Thereby, since the lock body 5 rotates backward as described above, the unlocked state in which the elevating body E1 can be lifted is obtained.

  In the unlocking UL when the authentication of the electronic lock B is successful, the power supply to the actuator M1 is performed only for a predetermined time, and the unlocking state is within the predetermined time. Therefore, as shown in FIG. Can be pulled out. That is, along with the movement of the drawer 11A, the operating body L1 moves the elevating body E1 upward as indicated by the arrow H1 in the figure and moves the elevating body E2 downward as indicated by the arrow H2 in the figure. Thereby, since the striker S1 of the trunk | drum G of drawer 11A can pass between the raising / lowering bodies E1 and E2, drawer 11A can be pulled out.

The middle and lower drawers 11B and 11C shown in FIG. 1 can be similarly pulled out in the unlocked state.
That is, when the drawer 11B at the middle stage is pulled out, the lifting body E2 is moved upward and the lifting body E3 is moved downward by the operation piece L2 along with the movement of the drawer 11B. Thereby, since the striker S2 of the trunk plate G of the drawer 11B can pass between the elevating bodies E2 and E3, the drawer 11B can be pulled out.
Further, when pulling out the lower drawer 11C, along with the movement of the drawer 11C, the lifting body E3 is moved upward and the lifting body E4 is moved downward by the operation piece L3. Thereby, since the striker S3 of the trunk plate G of the drawer 11C can pass between the elevating bodies E3 and E4, the drawer 11C can be pulled out.
In order to prevent the cabinet C from overturning, when a drawer at one stage is pulled out, it has a double drawer prevention function that makes it impossible to pull out drawers at all other stages.

In the state shown in FIG. 6 in which the drawer 11A is pulled out, the energizing terminal 16A and the energizing terminal 16B are separated from each other, so that the power supply to the actuator M1 is cut off, and the operating body 1A of the actuator M1 is energized (not shown). The return spring as a means tries to return to the state shown in FIGS. Therefore, the lock body 5 also tries to return to the state shown in FIGS. 2A and 3, but as shown in FIG. 6, the lock body 5 is brought into a stationary state with its front surface in contact with the upper end of the lift body E <b> 1. Become.
When the drawer 11A is closed from the state in which the drawer 11A is pulled out in this manner, the operation piece L1 comes out between the lifting bodies E1 and E2, and the lifting body E1 is lowered and the lifting body E2 is raised to the state shown in FIG. Become. That is, by closing the drawer 11A, the lock body 5 hangs downward and automatically returns to the all-locked state in which the ascending / descending body E1 is prevented from being lifted.

According to the configuration of the first embodiment as described above, the lock body 5 prevents the raising and lowering bodies E1 to E4 supported so as to be able to move up and down inside the side plates 12 and 13 of the cabinet main body 10, thereby The drawers 11A, 11B, and 11C can be pulled out by moving the lock body 5 so as not to prevent the raising and lowering bodies E1 to E4 from moving up.
Therefore, the operation for bringing the lifting bodies E1 to E4 into the unlocked state in which the elevators E1 to E4 can be raised and the operation for making the all-locked state are reliable, and the reliability of the operation is increased.
In addition, the all-lock device A1 that can lock the drawers 11A, 11B, and 11C in a plurality of upper and lower stages collectively is used, and the all-lock state is set by the biasing means, and the actuator M1 is operated only when the authentication of the electronic lock B is successful. Let
Therefore, the electronic lock B can suppress an increase in manufacturing cost while improving security, and can save power.

  In the above description, an example is shown in which power is supplied from the battery on the drawer 11A side to the actuator M1 on the cabinet body 10 side by pressing the conduction terminal 16A on the drawer 11A side against the conduction terminal 16B on the cabinet body 10 side. Instead of such contact power supply, the power supply may be performed by non-contact power supply by an electromagnetic induction method, a radio wave method, or the like. Alternatively, the drawer 11A may be configured to be openable and closable by allowing the actuator M1 on the cabinet body 10 side and the battery on the drawer 11A side to be always connected by a cable and loosening while protecting with a cable bear or the like.

Further, in the configuration in which the cabinet body 10 includes the actuator M1 that is a plunger-type solenoid that is provided with a return spring that is an urging unit and reciprocates linearly as in the first embodiment, the interlock member D1 and the lock body 5 are provided. You may make it not prepare.
In other words, the operating body 1A is arranged so as to advance and retreat above the lifting body E1 so that the actuator M1 operates in a direction (horizontal direction) orthogonal to the movement of the lifting bodies E1 to E4. In the unlocking UL when the authentication of B is successful, the operation body 1A is retracted by suction of the plunger based on the energization of the actuator M1, and the actuator M1 is deenergized except for the unlocking UL. Therefore, the ascending / descending bodies E1 to E4 are prevented from rising by the entry of the operating body 1A by the return spring.
Here, the lifting bodies E1 to E4 are provided only on one of the inner sides of the left and right side plates 12 and 13, and the lifting bodies E1 to E4 provided on the left and right sides with one actuator M1 for one authentication unit P and the battery are provided. Elevator bodies E1 to E4 may be provided on both inner sides of the left and right side plates 12 and 13, and the two actuators M1 and M1 are operated simultaneously on one authentication unit P and the battery, so You may make it regulate both the bodies E1-E4.
According to such a configuration, since the interlocking member D1 and the lock body 5 are not provided, the manufacturing cost can be reduced, and the operating force of the actuator M1 can be extremely weakened, so that further power saving can be achieved.

<Embodiment 2>
The cabinet C shown in the perspective view of FIG. 7 is provided with an all-lock device A2 for drawer in the cabinet according to Embodiment 2 of the present invention.

The left and right lock bodies 5, 5 that move, the left and right lock bodies 5, 5 that connect the connecting rod 4 that is the left-right axis, the gear 3 that is fixed to the center of the connecting rod 4 in the left-right direction, and the gear 3 are engaged. The gear 8 and the interlocking member D2 which consists of the linearly-moving body 7 which can slide to the up-down direction which has the tooth | gear part 7C meshing with the gear 8 are provided.
9, the drawer 11A includes an actuator M2 that operates in the unlocking state UL when the authentication of the electronic lock B is successful and drives the interlocking member D2.
The actuator M2 is, for example, a plunger-type solenoid that includes a return spring as an urging means and reciprocates linearly in the vertical direction. The hook-like portion 6 of the operating body 1B that operates integrally with the plunger (see, for example, FIG. 8A). ) Engages with the engaging portions 7A and 7B of the linear motion body 7.
In the interlocking member D <b> 2, power can be reliably transmitted with a light force by the rack and pinion including the tooth portion 7 </ b> C of the linear motion body 7 and the gear 8.

When the electronic lock B is locked L, the interlocking member D2 of the all lock device A2 is in the state shown in FIG. That is, the gear 3 fixed to the connecting rod 4 meshes with the gear 8 that rotates about the rotation shaft 8A, the gear 8 meshes with the tooth portion 7C of the linear motion body 7, and the upper and lower engaging portions of the linear motion body 7 The lock bodies 5 and 5 fixed to the left and right end portions of the connecting rod 4 hang downward and move left and right up and down in a state where the rod-shaped portion 6 of the operating body 1B of the actuator M2 is positioned between 7A and 7B. The ascending action of the bodies E1, E1 is prevented.
As a result, the all lock device A2 enters an all lock state in which the drawers 11A, 11B, and 11C are locked together.

The interlocking member D2 of the all-lock device A2 is in the state shown in FIG. 8B when unlocked when the authentication of the electronic lock B is successful. That is, since the actuator M2 is driven and the plunger is sucked downward, the operating body 1B moves downward from the position of FIG. 8A as shown by the arrow in FIG. 8A to the position of FIG. 8B. Drawn in. Since the engaging portion 7A of the linear moving body 7 is pulled downward by the flange portion 6 of the operating body 1B, the linear moving body 7 moves downward, and the gear 8 meshed with the tooth portion 7C and the gear 3 meshed with the gear 8 are obtained. Since it rotates, the connection rod 4 also rotates, and the left and right lock bodies 5, 5 having the connection rod 4 as a rotation axis rotate forward.
Thereby, all lock device A2 will be in the lock release state in which right and left raising and lowering bodies E1 and E1 can raise.

Next, the details of the operation of the drawer all lock device A2 in the cabinet according to the second embodiment of the present invention will be described mainly with reference to schematic views of the right side surface of the vertical cross section of FIGS.
In the locked state L of the electronic lock B with the drawer closed shown in FIGS. 8A and 9, the lock body 5 hangs downward to prevent the lifting body E <b> 1 from moving up, so that the all-lock state is established.
In this state, the hook-like portion 6 of the operating body 1B of the actuator M2 is engaged with the engaging portion 7A of the linear moving body 7.

  In unlocking UL when the authentication of the electronic lock B shown in FIGS. 8B and 10 is successful, power is supplied from the battery to the actuator M2 through the cable 19 as shown by an arrow in the figure, and the actuator M2 is driven. The Thereby, since the lock body 5 rotates forward as described above, the unlocking state in which the elevating body E1 can be lifted is obtained.

At the unlocking time UL when the authentication of the electronic lock B is successful, the power supply to the actuator M2 is performed only for a predetermined time, and the unlocking state is within the predetermined time. Therefore, as shown in FIG. Can be pulled out. That is, along with the movement of the drawer 11A, the operating body L1 moves the elevating body E1 upward as indicated by the arrow H1 in the figure and moves the elevating body E2 downward as indicated by the arrow H2 in the figure. Thereby, since the striker S1 of the trunk | drum G of drawer 11A can pass between the raising / lowering bodies E1 and E2, drawer 11A can be pulled out.
Note that the middle and lower drawers 11B and 11C shown in FIG. 7 can be similarly pulled out in the unlocked state.

In the state where the drawer 11A is pulled out as shown in FIG. 11 and the state where the drawer 11A is further pulled out as shown in FIG. 12, the hook-like portion 6 of the operating body 1B of the actuator M2 is engaged with the linear moving body 7 When the predetermined time elapses in a state of being separated from the portions 7A and 7B, the operating body 1B of the actuator M2 located on the drawer 11A side tries to return to the state shown in FIG. 9 by a return spring which is a biasing means (not shown). .
However, the operating body pressing piece 20 biased rearward, which is provided above the actuator M2 of the drawer 11A and can be rotated between, for example, a substantially upright state and a state of falling backward, pulls the operating body 1B. Since the operation body 1B is pressed from above and pushed down, the operating body 1B does not become the position of FIG. 9 moved upward, but the same position as the operating body 1B moved downward by sucking the plunger as shown in FIG. 11 and FIG. 12 is held.
Therefore, when the drawer 11A is closed from the pulled-out state, the operating body 1B of the actuator M2 does not collide with the engaging portion 7B of the linear motion body 7.
Since the operating force of the actuator M2 of the battery-type electronic lock B is weak, the spring constant of the return spring is small, so that the operating body pressing piece 20 for holding the operating body 1B at the position shown in FIGS. The pressing force is small.

When the drawer 11A is closed from the state in which the drawer 11A is pulled out as shown in FIG. 12, the operation piece L1 comes out between the lifting bodies E1 and E2, and the lifting body E1 is lowered and the lifting body E2 is raised as shown in FIG. It becomes a state.
That is, since the operating body pressing piece 20 is pressed forward while abutting against the front surface of the top plate 14 of the cabinet body 10, the operating body pressing piece 20 becomes substantially upright as shown in FIG. 9 and is detached from the operating body 1B.
Therefore, the operating body 1B of the actuator M2 is returned to the position extended upward as shown in FIG. 9 by the return spring, and accordingly, the linear motion body 7 in which the engaging portion 7B is pushed up by the operating body 1B is moved to the position shown in FIG. Return. Then, the hook-like portion 6 of the operating body 1B of the actuator M2 engages with the engaging portion 7A so as to be positioned above the engaging portion 7A of the linear motion body 7 (see also FIG. 8A).
Then, since the linear motion body 7 rises from the position of FIG. 12 to the position of FIG. 9, the gear 8 that meshes with the tooth portion 7C of the linear motion body 7 and the gear 3 that meshes with the gear 8 rotate. As a result, the connecting rod 4 also rotates, and the lock body 5 having the connecting rod 4 as a rotation axis rotates and hangs downward, so that the all-lock state in which the ascending / descending body E1 is prevented from being lifted is automatically set. Return to.

Even with the configuration of the second embodiment as described above, the same effects as the configuration of the first embodiment can be obtained.
In addition, since the drawer 11A includes the actuator M2 together with the battery, the reliability of power supply from the battery to the actuator M2 is increased.

In the above description, an example in which the power source of the electronic lock provided in one of the drawers of the cabinet is a battery has been shown.
Since power saving can be achieved by the present invention, the power source of the electronic lock is not limited to a battery, and may be a power source of a commercial power source, a private power generation facility, or the like.
