Description

Specification

Lockbox with key

Technical field

The present invention relates to a lockable storage used in an office, and more particularly, to a storage that can open and close storage boxes of a plurality of storages using the same single key. .

Background art

[0002] Conventionally, in an office, a key that can be opened and closed for each storage box in a storage is stored in a key management box, and a user opens and closes the key management box door by ID authentication such as an ID card. , Borrow a key for the storage box you want to use. The key management box is opened only when the user is authenticated by the ID card and the person has the right to access the storage box.

However, holding ID cards and keys separately is cumbersome, and if you want to examine documents in a large number of storage boxes, you have to move with a lot of keys. It was bad. In order to solve this problem, a system that can open and close multiple storage boxes using the same single key has been desired.

[0003] A master key is known as a system capable of opening and closing storage boxes of a plurality of storages using the same key. The master key is for emergency use, such as when the 1S key that can be opened and closed is lost.If the master key is used on a daily basis, a separate lock is attached and managed. The meaning is lost. Also, the right to access for each storage box cannot be set for each person.

On the other hand, an easy-to-change cylinder lock is used, and a storage box that can be opened and closed with one key can be set by exchanging the cylinder lock for each storage box. According to this, force S can be used to arbitrarily set and change the storage box that can be opened and closed with the same key.

[0004] Patent Document 1 discloses a technique that combines an IC tag and a key. In Patent Document 1, a contact-type IC tag is built in the key gripping part, and the key side exposed to a part of the gripping part is disclosed. It is disclosed that contact-type IC tag data is read by a door-side data terminal in contact with a data terminal, and when the data is not registered in ID, a solenoid prevents rotation of the key.

The key is a normal key and can be opened and closed only by a specific lock. As an effect, it is described that even if a key with the same key shape is made, the key cannot be released unless a contact IC tag is built in. Patent Document 1 describes that an electric lock is unlocked by authentication of only an IC tag.

Patent Document 1: Japanese Patent Laid-Open No. 09-059148

Disclosure of the invention

Problems to be solved by the invention

[0006] However, there are the following problems with the cylinder locks that are commercially available!

A system that can be used by a single person is fine, but in a system where multiple people with different authorities use the same storage box, such as a normal office in a company, each person can use it individually. It was difficult to have a key for a secure storage box. That is, for example, if people A, B, and C have the right to access different storage box groups, each person must have a key that can be used to open and close a storage box accessible to that person. I couldn't.

[0007] In addition, the system described in Patent Document 1 has the following problems.

In other words, contact IC tags are used only for confirmation, and the actual opening and closing of the key is based on the condition that the shape of the key insertion part matches the lock. So, if you want to examine documents in multiple storage boxes in multiple storages, you need to move between storages with a lot of keys. It was inconvenient to move with a lot of keys, and it was very inefficient because we had to find a certain key each time. Also, unlocking the electric lock by recognizing the IC tag is a combination of the IC tag and a key that makes no difference from simply reading the IC tag embedded in the card and unlocking the electric lock. There is no meaning. In other words, since it requires the electric lock, issues force ^s increase in cost. Further, in the technique of Patent Document 1, since the contact type IC tag is exposed to the key gripping part, the reading device must be arranged outside the lock, so that it is damaged by collision or mischief of equipment. There is a fear.

The invention's effect

Next, the operation and effect of the lockable storage having the above configuration will be described.

The data reading means authenticates the authority based on the access right read from the IC tag of the electronic key, and when the authority is judged to be valid, the storage box corresponding to the access right is allowed to open and close.

[0029] Each storage box is locked with a locking means disposed at a locking position. The data reading means authenticates the authority based on the access right read from the electronic key, and if it is judged that the authority is valid, the locking means corresponding to the access right is allowed to move from the locked position to the unlocked position. . As a result, the storage box can be opened and closed by moving the locking means from the locking position to the unlocking position.

[0030] In this case, each storage box is provided with a lock, the locking means is connected to the inner cylinder rotatably arranged on the outer cylinder of the lock, and the locking means is moved to the locked position and the unlocked position by the rotation of the inner cylinder. It can be so. Thus, if the rotation of the inner cylinder is prevented, the locking means is restricted from moving from the locking position, while if the inner cylinder rotation prevention state is released, the locking means can be moved from the locking position to the unlocking position. It becomes like this.

[0031] At this time, if the outer cylinder is fixed to a shielding plate that shields the opening of the storage box, the rotation prevention means directly prevents the rotation of the inner cylinder. Then, each rotation prevention means and each data reading means are connected to the lock control means, and when the data reading means determines that the authority is valid based on the access right read from the electronic key, it corresponds to the access right. Release the rotation prevention state of the inner cylinder. As a result, the storage box can be opened and closed by rotating the inner cylinder relative to the outer cylinder and moving the capping means from the locked position to the unlocked position.

[0032] Further, if the outer cylinder is rotatably held by the shielding plate that shields the opening of the storage box, the rotation prevention means prevents the rotation of the outer cylinder. The lock does not rotate with respect to the outer cylinder unless a matching key is inserted into the key hole of the inner cylinder. Therefore, the inner cylinder cannot be rotated while the outer cylinder is prevented from rotating. In this case, the data reading means If it is determined that the right is valid based on the access right read from the electronic key, the rotation prevention means corresponding to the access right releases the rotation prevention state of the outer cylinder, so that it is fitted in the fitting groove of the outer cylinder. If the electronic key inserted into the keyhole is rotated so that the inner cylinder can be rotated, the inner cylinder can be rotated integrally with the outer cylinder. As a result, the lock means can be moved from the locked position to the unlocked position, and the storage box can be opened and closed.

[0033] On the other hand, when the locking means disposed at the locking position is directly locked by the rotation prevention means, when the data reading means determines that the authority is valid based on the access right read from the electronic key, The rotation prevention means corresponding to the access right is released from the locked state of the lock means. As a result, the locking means can be automatically moved to the locking position force unlocking position, and the storage box can be opened and closed.

On the other hand, when the storage box is opened and closed by the opening / closing lever, the opening / closing lever is covered with a force bar to restrict the operation of the opening / closing lever so that the storage box cannot be opened / closed. When the data reading means determines that the right is valid based on the access right read from the electronic key, the cover is moved from the covering position covering the open / close lever to the open position where the open / close lever is opened. Allow movement. As a result, the storage box can be opened and closed by moving the cover to the open position and operating the open / close lever.

[0035] Thus, if the storage of the present invention is adopted in all the storages in the office, all the storage boxes in all the storages in the office can be obtained only by possessing the same electronic key. On the other hand, if the person has a legitimate authority, the storage box can be opened and closed to access the documents in the storage box. Even if multiple people use it, the IC tag built into the electronic key authenticates the individual, confirms the access rights to the storage box based on the authenticated data, and Since the openable / closable state is controlled, the user can open and close as many storage boxes as necessary with one electronic key while preventing opening and closing by persons without access rights.

[0036] In addition, since the electronic key inserted into the keyhole of the lock is rotated to rotate the inner cylinder and unlocking is performed by human power, it is possible to reduce the cost without requiring an electric lock. The shape of the insertion part of the electronic key is that if all electronic keys have the same rectangular parallelepiped shape, all electronic keys match all locks, so any electronic key rotates all locks. That power S. However, since all locks are provided with rotation prevention means for preventing rotation of the inner cylinder to which the electronic key is attached, the storage box can be opened only when the rotation prevention means is released. it can.

[0037] Information power of a contact-type IC tag built in the holding part of the electronic key. When the insertion part of the electronic key is inserted into the keyhole, it is read by the data reading means that comes into contact with the contact terminal, and is read by the data reading means. Based on the data, authority authentication of the storage box provided with the data reading means is performed, and when the authority is judged to be valid, the control means puts the rotation prevention state of the inner cylinder in the rotation prevention means corresponding to the data reading means. Release or allow the cover to move.

[0038] Since the contact IC tag is built in the holding part of the electronic key and the contact terminal of the contact IC tag is arranged in the insertion part, the contact IC tag can be protected and the data reading means can be locked. Since it can be installed inside, the data reading means cannot be touched from the outside and cannot be tampered with.

[0039] Since each storage box has a storage means for storing the opening / closing history, it is possible to record all accesses and to open / close all storage boxes in all storage boxes. You can leave a history.

[0040] In addition, since the lock can be exchanged with an existing lock, only the lock portion of the existing storage has to be replaced. Therefore, the lockable storage of the present invention can be employed at low cost. Further, when the rotation preventing means is constituted by a motor or a solenoid, and it is determined that the authority is valid based on the access right of the electronic key, the motor or solenoid is driven by an electronic signal so that the lock means is moved from the locked position. Since it is allowed to move to the unlocking position, the locking means can be easily unlocked.

In addition, the inner cylinder has a rotating plate attached to the back end, the solenoid or motor force constituting the rotation preventing means, the inner cylinder and the shaft center are attached in parallel, and the solenoid rod or motor rod is attached to the rotating plate. Since the structure that prevents rotation is adopted, the solenoid or motor can be arranged in parallel with the inner cylinder, so that the whole can be made compact.

[0041] Further, since the electronic key can be detached from the lock only when the shielding plate shields the opening, the shielding means such as the door is always closed when the electronic key is attached or detached. . That is, the electronic key cannot be removed with the door open. On the other hand, since the history of attaching / detaching the electronic key is stored, it is possible to specify the person in charge when leaving the electronic key for a long time and leaving the storage. An alarm means may be provided for alerting the user to remove the electronic key when the shielding means such as the door is closed, thereby preventing the user from forgetting to remove the electronic key after closing the shielding means.

[0042] Further, by allowing the lock control means or the cover opening / closing control means to store data for authority authentication, the authority authentication is performed without connecting the lockable storage to the host device via a network or the like. Therefore, it is possible to save the labor and time of wiring work for connecting the lockable storage to the host device and to reduce the installation cost of the lockable storage. On the other hand, if the lock control means or cover opening / closing control means is connected to a separately installed authentication means via a network and the authority is authenticated based on the data stored in the authentication device, the authority authentication is performed. Data corruption can be prevented.

By the way, in an emergency such as a power failure, the data reading means may not be able to read the access right from the electronic key, and the storage box may not be opened / closed using the electronic key. Even in this case, if a suitable emergency key is inserted into the keyhole of the lock, the inner cylinder is rotated to move the locking means from the locked position to the unlocked position, or the cover is moved from the covered position to the opened position. The storage box can be opened and closed.

BEST MODE FOR CARRYING OUT THE INVENTION

[0046] An embodiment of the present invention will be described.

[0047] [First embodiment]

<Storage configuration> Hereinafter, a first embodiment embodying a lockable storage of the present invention will be described in detail with reference to the drawings. Figure 5 shows an external view of the lockable storage. Three storages 51, 52, 53 are installed in succession. The storage 51 includes one double-folded storage box 51A, and the storage 52 includes one double-folded storage box 52A and three drawer-type storage boxes 52B, 52C, and 52D. The storage 53 has the same configuration as the storage 52. Each storage box is provided with a lock 20 (an example of “opening / closing permission means” and “moving means”). On the upper surface of the storage 51, a lock control means 40 for controlling each storage box of the three storages is attached.

FIG. 1 is an exploded perspective view showing the structure of the lock 20 and the electronic key 19 attached to the lockable storage. FIG. 2 shows a state where the electronic key 19 and the lock 20 are separated. FIG. 3 shows a state where the electronic key 19 is inserted into the lock 20.

The lock 20 and the electronic key 19 employ an electronic key system that permits the storage box to be unlocked based on the access right stored in the contact IC tag 5 of the electronic key 19. The electronic key 19 (an example of an “electronic key”) has a contact IC tag 5 and a pair of terminal plates 3 and 4 (of the “contact terminal”) between two resin key boards 1 and 2. (Example) is sandwiched between. The contact type IC tag 5 is commercially available, and each of the contact type IC tags 5 stores a unique numerical sequence. When the electronic key is used, the stored number is read out and stored by the control side, and the electronic key 19 can be identified separately by comparing the stored number sequence. Here, “registration on the control side using an electronic key” refers to communication that is performed only when the electronic key is inserted into the lock 20 and the lock control means 40 or the personal computer 44 registers the electronic key. This includes the case where the electronic key is registered by other methods, such as reading the numeric string of the contact IC tag 5 using the means and storing the electronic key on the control side. Two contacts are exposed on the back of the contact IC tag 5. The contact portions 3b and 4b formed at one ends of the pair of terminal plates 3 and 4 are in contact with the two contact points by the panel force of the plate panel.

The key substrate 1 has a recess la for storing the contact IC tag 5 in the grip portion. In addition, grooves lb and lc for accommodating the terminal plates 3 and 4 are formed. The contact portions 3a and 4a of the terminal plates 3 and 4 exposed to the outside are supported from the back side at the end of the grooves lb and lc. Convex parts Id, le for holding are formed.

[0049] When the terminal plates 3 and 4 are mounted in the grooves lb and lc, the terminal plates 3 and 4 are mounted without contacting each other. Then, the key board 2 is put on and the key boards 1 and 2 are fixed tightly with the two screws 7. As a result, the contact portions 3a and 4a of the terminal plates 3 and 4 are exposed to the outside through the contact windows 2b and 2c. At this time, the contact portions 3a and 4a are supported on the back side by the convex portions Id and le. Attach the contact type IC tag 5 from the window 2a and fix the cover 6 with the screw 7. As a result, the contact-type IC tag 5 is connected to the two contact force terminal plates 3a and 4a, respectively, and exposed to one surface of the insertion portion 21 of the electronic key 19. The completed electronic key 19 includes a grip portion 22 and a rectangular parallelepiped insertion portion 21.

The key substrates 1 and 2 have notches If and 2d formed at the same location.

[0050] <Structure of lock>

Next, the structure of the lock 20 will be described. A cylindrical inner cylinder 8 is rotatably held in a cylindrical hole 12a formed in the lock body 12 (an example of an “outer cylinder”). A collar 8 a is formed at the end of the inner cylinder 8, and the collar 8 a protrudes from the hole 12 a, and the inner cylinder 8 is positioned with respect to the lock body 12 in the axial direction.

A cutout 8d is formed on the side surface of the inner cylinder 8. A data reading board 9 for reading numerical data of the contact IC tag 5 by attaching to the contact IC tag 5 is attached to the notch 8d. An arcuate groove 8c is formed on the side surface of the inner cylinder 8. A C-ring mounting groove 8b is formed at the end of the inner cylinder 8 opposite to the collar 8a. By attaching the inner cylinder 8 to the lock body 12 and attaching the C ring 16 to the C ring mounting groove 8b, the inner cylinder 8 is rotatably attached to the lock body 12. A screw hole is formed in the end surface of the inner cylinder 8 opposite to the collar 8a, and the rotating plate 17 is fixed by the screw 18 so as to rotate integrally with the inner cylinder 8. The rotating plate 17 is formed with a square hole 17b for positioning and fixing to the inner cylinder 8 and a 90 degree angle difference, and a rod of solenoid 14 (an example of "unlocking permission means" and "rotation prevention means") Anti-rotation grooves 17a and 17c into which 15 is inserted are formed.

[0051] The lock body 12 is formed with a hinge 11 for attaching to a storage box door or the like of the storage. An attachment box 13 for attaching the solenoid 14 is formed. A solenoid 14 having a rod 15 is attached to the mounting box 13. The lock body 12 An arcuate groove 12c is formed on the side surface at a position corresponding to the arcuate groove 8c. A convex portion 12b is formed in the vicinity of the arc-shaped groove 12c. The bracket 10 is attached to the convex portion 12b. The bracket 10 is formed with an anti-extraction claw 10a, and the anti-extraction claw 10a enters the arc-shaped groove 12c and the arc-shaped groove 8c so that the notch formed on the electronic key 19 is formed. Engageable with If, 2d.

[0052] <Control configuration of lockable storage>

Next, FIG. 4 shows a block diagram of the control of the lockable storage of the present invention. The lock control means 40 includes a CPU 41 as a control means, a ROM 43 for storing a control program, an opening / closing history of storage boxes (who opened, when opened, when closed), and contact with access rights for each storage box. Formula Equipped with RAM to store IC tag data! The lock control means 40 is connected to the personal computer 44 via a LAN. The personal computer 44 stores the data of the contact type IC tag having the access right for each storage box, and corrects the data. When the access right data is corrected, the computer 44 corrects the data in the RAM 42. The computer stores the opening / closing history of the storage box in the same manner as the RAM 42. By storing data in two locations, data safety is enhanced.

The lock control means 40 and all the lock 20 data reading boards 9A, 9B, 9C,..., Solenoids 14A, 14B, 14C,. Here, when the personal computer 44 cannot be used, that is, for example, when it is desired to configure a stand-alone and inexpensive system, the lock control means 40 is provided with a registration means such as a key switch, and the person who has the authority to change the access right data. It may be possible to switch to a mode that enables the registration function by entering the encryption number using the key switch. When the contact IC tag 5 is read in the mode in which the registration function is enabled, it is preferable to be able to directly register and store the data in the RAM 42.

Next, a system for managing the electronic key 19 will be described. Figure 6 shows the configuration of the key management system. The key management box 30 is provided with an open / close door 31 and the normal door open / close door 31 is closed. Ten locks 36 are placed inside the door 31 of the key management box 30. In addition, a key hole for holding the electronic key 19 is provided. The key management box is provided with a card reader 32, a numeric keypad 33, and a liquid crystal display 34. The key management box 30 is connected to the personal computer 44 via a LAN. Each lock 36 is in a state in which the electronic key 19 cannot normally be pulled out by a key drop prevention means (not shown).

[0054] <Description of Action>

Next, the operation of the lockable storage according to the first embodiment will be described.

The user goes to the key management box 30 and causes the card reader 32 to read the ID card he has. Then, the encryption number is input by the numeric keypad operation unit 33. The personal computer 44 stores an encryption number corresponding to the card read by the card reader 32, and opens the door 31 only when the correct encryption number is input. In the present embodiment, the numeric operation unit 33 is used, but personal authentication may be performed by a vein authentication device, a fingerprint authentication device, or the like. The purpose of personal authentication is to prevent fraudulent acts using other people's cards.

At the same time as opening the door 31, the computer 44 releases the lock release prevention means of the lock 36 to which the electronic key 19 having access authority for the individual who has been personally authenticated is installed. The key removal prevention means may be configured to drive an engagement claw (not shown) with a solenoid using the notches If and 2d of the electronic key 19. In this way, the user can remove the electronic key 19 required. The computer 44 stores the authenticated individual, the electronic key 19 that was taken out, and the time that it was taken out.

In this key management box 30, since the electronic key 19 is directly attached to the lock 36, if the means for reading the contact IC tag 5 is attached to the lock 36, whether or not the electronic key 19 is a regular key. Can be managed reliably.

[0055] The user who possesses the electronic key 19 goes to the lockable storage location where the storage box to be used is located, and inserts the electronic key 19 into the lock 20 of the storage box. When the electronic key 19 is inserted into the lock 20, the contact portions 3 a and 4 a exposed from the contact windows 2 b and 2 c of the insertion portion of the electronic key 19 are connected to the data reading board 9. The data reading board 9 passes a current through the contact portions 3a and 4a, and reads a numerical sequence stored in the contact IC tag 5. The read numerical sequence is sent to the lock control means 40. The lock control device 40 stores the number stored in the RAM. Search for a match with the value string. If there is a match, the electronic key of the numeric column 19 forces whether or not there is an authority to access the storage box to which the lock 20 currently inserted is attached, and the data stored in the RAM 42 Judgment based on. When it is determined that the authority is valid, a drive signal is given to the solenoid 14 to retract the rod 15 of the solenoid 14 and release the rod 15 from the rotation prevention groove 17a of the rotating plate 17. As a result, the user can rotate the electronic key 19. Since the insertion part of the electronic key 19 has a rectangular parallelepiped shape, it is possible to easily rotate the inner cylinder 8 with respect to the lock main body 12 by a couple of forces S. By rotating the inner cylinder 90 by 90 degrees, the locking mechanism (not shown) is released because it is a normal locking mechanism, and the user can open the door or pull out the drawer. And you can access the internal documents.

[0056] On the other hand, when it is determined based on the data that it is determined that there is no right authority, the solenoid 14 is not driven, so that the user can remove the inner cylinder 8 while the rotating plate 17 remains locked. It cannot be rotated and the door cannot be opened or the drawer cannot be pulled out.

When the electronic key 19 is rotated, the user cannot pull out the electronic key 19 from the inner cylinder 8 because the extraction preventing claw 10a is engaged with the cutout If, 2d of the electronic key 19.

When the user has finished accessing the document, the user closes the door and rotates the electronic key 19 by 90 degrees to restore the original state. As a result, the engagement between the cutout If, 2d of the electronic key 19 and the extraction preventing claw 10a is released, so that the user can extract the electronic key 19 from the lock 20. When the electronic key 19 is removed, the data reading board 9 cannot detect the contact IC tag 5, so the lock control means 40 determines that the electronic key 19 has been removed and stops energizing the solenoid 14. Then, the rod 15 is moved by a spring force so that the rod 15 is engaged with the rotation preventing groove 17a of the rotating plate 17 so that the rotating plate 17 cannot rotate.

[0057] In this embodiment, the force of the electronic key 19 that can be extracted only by the origin is changed by the shape of the extraction preventing claw 10a. The shape of the extraction preventing claw 10a is changed, and the extraction position of the electronic key 19 is changed to the origin ( It may be set at two locations, 0 degrees and 90 degrees. However, using only the origin can increase the level of security because the electronic key 19 can be removed only when the door is closed. In particular, the lock control means 40 has a state in which the force door storing the time when the electronic key 19 is inserted, the contact type IC tag data of the electronic key 19 and the time when the electronic key 19 is extracted as a history is opened. Since it is not detected whether the electronic key 19 is applied or not, the security is higher when the electronic key 19 is removed only when the electronic key 19 is applied.

[0058] <Operation and effects of the lockable storage according to the first embodiment>

As described in detail above, according to the lockable storage of the present embodiment, a plurality of storage boxes are provided, and a lock 20 is provided on a shielding plate provided at each opening of the storage box. The lock 20 is a lock main body 12 fixed to the shield plate, the inner cylinder 8 having a keyhole rotatably disposed in the lock main body 12, a solenoid 14 for preventing the inner cylinder 8 from rotating, and a contact IC tag 5 The electronic key 19 is inserted into the keyhole in a storage cabinet with a key that includes the data reading board 9 that reads the data of the contact IC tag 5 when the electronic key 19 containing the key is inserted into the keyhole. And a gripping part provided at one end of the insertion part, the shape of the insertion part is a rectangular parallelepiped shape, and the contact terminals 3a and 4a of the built-in contact IC tag 5 are provided in the insertion part. Fixed to the cabinet and connected to each data reading board 9 and each solenoid 14. When the data reading board 9 authenticates the authority of the storage box provided with the data reading board 9 based on the read data and determines that the authority is valid, the solenoid corresponding to the data reading board 9 14 has the lock control means 40 for releasing the rotation prevention state of the inner cylinder 8, so that it has only one electronic key 19 for all storage boxes of all storage boxes in the office. If the person has legitimate authority, the solenoid 14 can be released and the document inside can be accessed. Even if multiple people use it, the contact IC tag 5 built in the electronic key 19 authenticates the individual, confirms the access right to the storage box based on the authenticated data, and stores it. Since the open / close state of the box is controlled, the user can open and close many storage boxes required by one electronic key 19 while preventing opening and closing by a person without access right.

[0059] Further, since the contact IC tag 5 is built in the holding part of the electronic key 19 and the contact terminals 3a and 4a of the contact IC tag 5 are arranged in the insertion part, the contact IC can be protected. At the same time, since the data reading board 9 of the contact IC tag 5 can be installed inside the lock, the data reading board 9 cannot be touched from the outside and will not be tampered with! / ,. Further, since the lock control means 40 has storage means 42 for storing the opening / closing history for each storage box, it is possible to record all accesses, and for all storage boxes in all storage boxes. , You can leave a history of opening and closing.

In addition, the inner cylinder 8 has a rotating plate 17 attached to the back end, a solenoid 14 force is an inner cylinder 8 and a solenoid 14 whose axes are mounted in parallel, and the solenoid rod 15 is attached to the rotating plate 17 Since the rotation is prevented, the solenoid 14 can be arranged in parallel with the inner cylinder 8, so that the whole can be made compact.

In addition, since the electronic key 19 can be detached from the lock body 12 only when the shielding plate covers the opening, the electronic key 19 is left on for a long time and it is left away from the storage. The person responsible can be identified, and the security level can be increased. In particular, an alarm means that alerts the user to pull out the electronic key when the shielding means such as a door is closed is connected to the lock control means 40, and data is read even after a few seconds have passed since the lock control means 40 closed the shielding means. When the data of the electronic key 19 is read by the substrate 9, if an alarm such as a buzzer sound or a message is issued from the alarm means, it is possible to prevent the electronic key 19 from being forgotten after the shielding means is closed.

[0060] [Second Embodiment]

Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 7 is a partially enlarged front view of the lockable storage 60 according to the second embodiment of the present invention.

The lockable storage 60 of the second embodiment employs an electronic key system as in the first embodiment, but uses a lock 70 (an example of “open / close permission means” and “moving means”) having an emergency unlocking function. The use and the shape of the electronic key 19A are different from those of the first embodiment. Therefore, here, the description will focus on the points that differ from the first embodiment, and the points that are common to the first embodiment will be assigned the same reference numerals as the first embodiment in the drawings, and the description thereof will be omitted as appropriate.

[0061] <Configuration of lockable storage>

The lockable storage 60 has the same form as the lockable storage 52 shown in FIG. 5. For example, the opening of the storage button 60A is a double door opening / closing door 61A, 61B (an example of a “shielding plate”). Shielded. The lock 70 is attached to each storage box of the lockable storage 60 and is an electronic key 19A with a built-in contact IC tag 5 or a mechanical emergency key that locks and unlocks the doors 61A and 61B. Do the lock.

[0062] The lock 70 is attached to the door 61B. The lock 70 is connected to a lock plate 62 (an example of a lock means) and rotates the lock plate 62. The lock plate 62 is engaged with a strike 63 provided on the opening / closing door 61A to lock the opening / closing door 61A, 61B, and the engagement state with the strike 63 is released to unlock the opening / closing door 61A, 61B. It is placed at the unlocking position. An LED 64 is arranged on the upper side of the lock 70 on the opening / closing door 61B.

[0063] <Structure of electronic key>

FIG. 10 shows the internal structure of the electronic key 19A.

In the electronic key 19A, a metal case 81 inserted into the lock 70 is covered with a resin case 82, thereby forming an insertion portion 21 and a grip portion 22. The insertion body 81 includes a frame portion 81a accommodated in the case 82, and an insertion portion 81b extending from the case 82 so as to protrude to the outside.

[0064] An opening 81c is formed in the frame 81a. The wiring of the contact type IC tag 5 and the LED 84 mounted on the IC tag substrate 83 is disposed in the opening 8 lc so as not to contact the metal plug 81. On the IC tag substrate 83, the contact IC tag 5, the terminal plates 3 and 4 of the contact IC tag 5, and the LED 84 are attached by soldering or the like. The IC tag board 83 has an electrical circuit configuration that connects the LED 84 to the contact IC tag 5 in parallel, and uses the current flowing between the terminal plates 3 and 4 of the contact IC tag 5 to light the LED 84. It has become.

In the IC tag substrate 83, extending portions 83a and 83b are extended in parallel at a predetermined interval. The terminal plates 3 and 4 are mounted on the extending portions 83a and 83b and insulated from the plug 81. In the case 82, ribs 82a for positioning and holding the IC tag substrate 83 are erected on the inner wall.

[0065] Extension portions 83a and 83b are tightly fixed to both end surfaces of the insertion portion 81b in a state of being exposed to the outside of the case 82. The terminal plates 3 and 4 installed in the extending portions 83a and 83b are also arranged on both end surfaces of the insertion portion 81b so as to be exposed to the outside of the case 82. At the edge portion of the insertion portion 81b, the stagger portions 81d and 81e are projected in a protruding manner at positions corresponding to the end portions of the terminal plates 3 and 4.

[0066] <Specific composition of the lock> FIG. 8 is a cross-sectional view taken along line AA in FIG. FIG. 9 is a cross-sectional view taken along the line BB in FIG. The lock 70 is a unitized cylinder lock that can be easily retrofitted. The lock 70 is positioned so that the inner cylinder 71 and the outer cylinder 72 are fitted into a through hole 67 formed in the opening / closing door 61B, and has a mounting plate 73 that rotatably holds the inner cylinder 71 and the outer cylinder 72. It is attached to the storage box 60A by being fixed to the back side of the door 61B with a screw 74.

[0067] The lock 70 includes an outer cylinder 72 that is rotatably attached to the open / close door 61B via an attachment plate 73, and an inner cylinder 71 that is rotatably arranged in the outer cylinder 72 and has a key hole 71a. The lock 70 can rotate the inner cylinder 71 with respect to the outer cylinder 72 by inserting a suitable key into the key hole 71a. In the present embodiment, it is assumed that the emergency key is a key that fits into the keyhole 71a.

[0068] The inner cylinder 71 is formed of a metal in a substantially cylindrical shape in order to ensure rigidity. A collar 71b is provided at one end of the inner cylinder 71. The key hole 71a is formed in the inner cylinder 71 along the axial direction of the inner cylinder 71 by the end face force provided with the collar 71b. As shown in FIG. 8, the collar 71b has a pair of mounting recesses 71c and 71c formed at symmetrical positions with the key hole 71a interposed therebetween. In each mounting recess 71c, 71c, a data reading board 75 (an example of “data reading means”) that reads data from the contact IC tag 5 by contacting the terminal plates 3, 4 of the electronic key 19A is an adhesive or the like. It is fixed in each.

[0069] Also, as shown in FIG. 9, the key hole 71a is symmetrically positioned around the key hole 71a of the collar 71b at a position shifted by 90 degrees from the pair of locking grooves 71d, 71d 1S mounting recesses 71c, 71c. It is formed at the position. The locking grooves 71d, 71d are formed with the same width as the key hole 71a. The locking grooves 71d, 71d have the inner wall on the back side locked against the stoppers 81d, 81e of the electronic key 19A inserted into the key hole 71a to lock the terminal plates 3, 4 into the data reading board. Position 75 and 75 in the axial direction.

As shown in FIGS. 8 and 9, an annular groove 71 e is formed on the outer peripheral surface of the inner cylinder 71.

A screw hole 71f is formed in the rear end surface of the inner cylinder 71, and the lock plate 62 is fixed by a screw 65 that is fastened to the screw hole 71f.

[0071] The outer cylinder 72 has a cylindrical shape having a diameter larger than that of the inner cylinder 71. The outer cylinder 72 is formed with a hollow hole 72a penetrating in the axial direction. The hollow hole 72a is slidably loaded into the inner cylinder 71, and The cylinder 71 and the outer cylinder 72 are positioned in the radial direction. A collar 72b is provided on the outer peripheral surface of one end of the outer cylinder 72 so as to protrude outward. On the end surface of the collar 72b, a positioning recess 72c is provided in a circular shape coaxially with the hollow hole 72a. The positioning recess 72c accommodates the collar 71b of the inner cylinder 71 passed through the hollow hole 72a, and positions the inner cylinder 71 with respect to the outer cylinder 72 in the axial direction. The inner cylinder 71 positioned with respect to the outer cylinder 72 has a C-ring 66 attached to the annular groove 71e to prevent the inner cylinder 71 from falling off the outer cylinder 72. The outer cylinder 72 is attached to the mounting plate 73 via a bearing 80, and is rotatably held by the mounting plate 73.

[0072] Further, the collar 72b is formed with a fitting groove 72d into which the stopper portion 81e (81d) of the electronic key 19A inserted into the key hole 71a of the inner cylinder 71 is fitted. Therefore, when the electronic key 19A is inserted into the key hole 71a, the stopper 81e (81d) force is fitted into the locking groove 71d and the fitting groove 72d of the inner cylinder 71, and the inner cylinder 71 and the outer cylinder 72 are rotated together. It becomes possible to make it.

As shown in FIG. 8, the outer peripheral surface of the outer cylinder 72 has a rotation prevention hole 72e that engages with a rod 77 of a solenoid 76 (an example of “unlocking permission means” and “rotation prevention means”). Is formed. The solenoid 76 has a casing 79 attached to the outer peripheral surface. The solenoid 76 is disposed on the side of the outer cylinder 72 so that the rod 77 faces the outer cylinder 72, and is fixed to the mounting plate 73 by screwing the casing 79 to the mounting plate 73. The rod 77 is always given a force in a direction protruding from the solenoid 76 by a compression spring 78.

[0074] <Control configuration of lockable storage>

Fig. 11 is a control block diagram of the lockable storage.

The lock control means 40 includes all the locks 70A, 70B, 70C… attached to each storage box, data reading boards 75A, 75B, 75C…, solenoids 76A, 76B, 760 ···, LEDs 64A, 64B, 64C Power is connected by self-spring.

[0075] <Description of operation>

Next, the operation of the lockable storage according to the second embodiment will be described.

The electronic key 19A is distributed to each user. Each electronic key 19A stores an “access right” in the contact IC tag 5. Here, the “access right” means a right that allows the user holding the electronic key 19A to access the inside by opening and closing the storage box. The “access right” stored in the contact-type IC tag 5 is not limited to one, but may be plural. Not too long.

[0076] The user inserts the electronic key 19A possessed into the key hole 71a of the storage box to be opened. At this time, the user inserts the electronic key 19A into the key hole 71a until the stopper portions 81d, 81e of the electronic key 19A abut against the locking grooves 71d, 71d of the lock 70 and are locked. Then, in the electronic key 19A, the terminal plates 3 and 4 come into contact with the data reading boards 75 and 75. The data reading boards 75 and 75 pass current through the terminal boards 3 and 4 and read the access right data stored in the contact IC tag 5.

[0077] While the data reading boards 75 and 75 pass current through the terminal boards 3 and 4 to read the data of the contact IC tag 5, the data reading boards 75 and 75 are connected in parallel with the contact IC tag 5 between the terminal boards 3 and 4. A current also flows through the LED 84. Therefore, the LED 84 is lit using the current flowing through the terminal plates 3 and 4. For this reason, the user can confirm whether or not the data of the contact IC tag 5 is read by the data reading boards 75 and 75 from the blinking state of the LED 84. In other words, when the LED 84 of the electronic key 19A inserted into the key hole 71a is not lit, the user does not normally contact the terminal boards 3 and 4 with the data reading boards 75 and 75, and the contact type IC tag 5 It is easy to visually check for poor readings that cannot be read.

The lock control means 40 verifies the access right read by the data reading terminals 75 and 75 against the data stored in the RAM 42 and performs authority authentication. If it is determined that the authority is valid, the solenoid 76 is energized and the rod 77 is pulled into the solenoid 76 against the compression spring 78. The rod 77 is detached from the rotation prevention hole 72e of the outer cylinder 72. As a result, the outer cylinder 72 is released from the locking force S and can rotate. The lock control means 40 energizes the solenoid 76, and at the same time, sends current to the LED 64 to light the LED 64. Therefore, the user can know whether or not the lock 70 can be unlocked by the blinking state of the LED 64.

[0079] After the LED 64 is turned on, the user rotates the electronic key 19A. In the electronic key 19A, the stopper portion 81e is fitted in the locking groove 71d of the inner cylinder 71 and the fitting groove 72d of the outer cylinder 72. Therefore, when the electronic key 19A is rotated, the inner cylinder 71 and the outer cylinder 72 rotate integrally. The lock plate 62 rotates integrally with the inner cylinder 61 and moves from the locked position to the unlocked position. As a result, the lock plate 62 is disengaged from the strike 63, and a force S for opening the open / close doors 61A and 61B can be obtained. On the other hand, the lock control means 40 does not energize the solenoid 76 when it is determined that the authority is not valid as a result of the authority authentication based on the data read by the data reading board 75. Therefore, the solenoid 76 also pushes the rod 77 with the force of the solenoid 76 due to the urging force of the compression spring 78, keeps engaging with the rotation prevention hole 72e of the outer cylinder 72, and prevents the rotation of the outer cylinder 72. In the electronic key 19A, the inner cylinder 71 cannot rotate with respect to the outer cylinder 72 because the insertion portion 21 is not shaped to fit the key hole 71a.

[0081] Therefore, for example, if the user accidentally inserts the electronic key 19A into the lock 70 of the storage box to which the user does not have access right, the right authority is not authenticated and the user rotates the electronic key 19A. The lock 70 cannot be unlocked. As a result, the user cannot open and close the storage box to which he / she does not have the right to access without permission, and can use the force S to increase the security of the lockable storage 60.

The user opens the open / close doors 61A and 61B to access desired materials and then closes the open / close doors 61A and 61B. Then, the user rotates the electronic key 19A in the reverse direction to return to the original state, and moves the lock plate 62 from the unlocked position to the locked position. Thereby, the lock plate 62 engages with the strike 62 and locks the open / close doors 61A and 61B. The lock control means 40 detects that the lock plate 62 has been moved from the unlocked position to the locked position with a not shown! /, Limit switch, etc., and turns off the LED 64. The user confirms that the doors 61A and 61B are locked by turning off the LED 64, and removes the electronic key 19A from the key hole 71a.

[0083] The lock control means 40 determines that the electronic key 19A has been removed when the data reading board 75 cannot read data from the contact IC tag 5, and the unlocking time when the user unlocked the lock 70, The RAM 42 stores the locking time, the personal ID assigned to each user, the identification number for identifying the electronic key 19A used, and the like. These data are also stored in the personal computer 44. Therefore, by referring to the use history stored in the RAM 42 or the personal computer 44, it is possible to know who has opened and closed which storage box, and when it has been closed and locked.

[0084] Here, if the user removes the electronic key 19A from the key hole 71a with the open / close doors 61A and 61B open, the stored item stored in the lockable storage 60 is lost. RAM42 Responsibility is pursued based on the stored usage history. For this reason, in order to avoid pursuing responsibility, the user is accustomed to closing the open doors 61A and 61B and locking them securely, and the security of the lockable storage 60 is inevitably enhanced.

In the present embodiment, the contactless IC tag 5 is adopted because the contactless IC tag may cause reading failure due to buffering of radio waves or the like. In general, there is a concern that the contact IC tag 5 does not normally contact the data reading boards 75 and 75 and cannot read data when the terminal plates 3 and 4 are contaminated with an oil film or the like. When data reading failure occurs, the lock control means 40 does not recognize the locking or unlocking, which greatly impairs the reliability of the system that manages the locking and unlocking. However, in the electronic key 19A of the second embodiment, whether or not the data reading boards 75 and 75 have contacted the terminal boards 3 and 4 normally and read the data of the contact IC tag 5 depending on the blinking state of the LED 84. You can check that. The user inserts the electronic key 19A into the key hole 71a of the lock 70 so as to turn on the LED 84, and locks and unlocks it in order to avoid responsibility for the loss of stored goods if it is stolen. Therefore, in the lockable storage 60, the reading failure of the data of the contact IC tag 5 is inevitably improved by the user, and the reliability of the system for managing the locking and unlocking can be drastically improved.

[0086] It should be noted that in the lockable storage of the second embodiment, when an emergency such as a power failure occurs, the bath 44, the lock control means 40, and the solenoid 76 are not operated, so the electronic key 19A is used. Unable to unlock lock 70 and open / close storage box. In such an emergency, a mechanical emergency key is inserted into the keyhole 71a instead of the electronic key 19A. If the emergency key does not fit into the fitting groove 72d of the outer cylinder 72 but has a shape that fits into the key hole 71a, the force S for rotating the emergency key can be increased. In this case, the inner cylinder 71 rotates with respect to the outer cylinder 72, the lock plate 62 is moved from the locked position to the unlocked position, and the open / close doors 61A and 61B can be opened and closed.

[0087] On the other hand, when the emergency key does not fit into the key hole 71a, the inner cylinder 71 does not rotate with respect to the outer cylinder 72, and the outer cylinder 72 engages the rotation preventing hole 72e with the rod 77 of the solenoid 76. Because the rotation is blocked, the user cannot rotate the emergency key. Therefore, the lock plate 62 does not move from the locked position to the unlocked position, and the user cannot open and close the open / close doors 61A and 61B.

<Effects of lockable storage according to the second embodiment> The lockable storage 60 according to the second embodiment performs authority authentication based on the access right that the data reading boards 75 and 75 read from the contact IC tag 5 of the electronic key 19A, and determines that the authority is valid. The storage box 60A corresponding to the access right is allowed to open and close

That is, each storage box 60A, 60B, 60C,... Is locked with the lock plate 62 arranged at the locking position. When the data reading means 75, 75 authenticate the authority based on the access right read from the electronic key 19A and determine that the authority is valid, the lock plate 62 corresponding to the access right is moved to the unlocking position from the locking position force. Allow to move. As a result, the lock plate 62 can be moved to the unlocked position from the locking position force, and the storage box for which the access right is authenticated can be opened and closed to access the inside.

[0090] In this case, each pre-regulation box 60A, 60B, 60C ... is provided with pre-regulation 70A, 70B, 70C ..., and can be rotated to the pre-regulation 70A, 70B, 70C outer cylinder 72A, 72B, 72C ... An inner cylinder placed in 71

A, 71B, 71C ... can be connected to lock play rods 62A, 62B, 62C ..., and the lock plates 62A, 62B, 62C can be moved to the locked and unlocked positions by rotating the inner cylinders 71A, 71B, 71C ... Like that. As a result, if the rotation of the inner cylinders 71A, 71B, 71C,... Is prevented, the lock plates 62A, 62B, 62C,...

When the rotation prevention state of B, 71C... Is released, the lock plates 62A, 62B, 62C... Can be moved from the locked position to the unlocked position.

[0091] In the second embodiment, the outer cylinders 72A, 72B, 72C ... force S are rotatably held by a shielding plate such as an open / close door 61B that shields the opening of the storage boxes 60A, 60B, 60C ... 6A, 76B, 76C ... rods, 77A, 77B, 77C ... engage with rotation prevention holes 72e of outer cylinders 72A, 72B, 72C ... to prevent rotation of outer cylinders 72A, 72B, 72C ... Yes. The locks 70A, 70B, 70C, etc. are the inner cylinders 71A, 71B, 71C ... force outer cylinder 72A as long as the appropriate key (emergency key) cannot be inserted into the key hole 7 la of the inner cylinder 71A, 71B, 71C ... , 72B, 72C ... Does not rotate. For this reason, the inner cylinders 71 A, 71B, 71C,... Cannot be rotated while the rotation of the outer cylinders 72A, 72B, 72C,. In this case, when the data reading means 75A, 75A, 75B, 75B, 75C, 75C,... Judges that the authority is valid based on the access right read from the electronic key 19A, the solenoid 76 corresponding to the access right is energized. Rod By pulling 77 to the solenoid 76 side and removing the rod 77 from the rotation prevention hole 72e, the rotation prevention state of the outer cylinder 72 is released.Therefore, the key hole 7 la is fitted into the fitting groove 72d of the outer cylinder 72. If the inserted electronic key 19A is rotated, the force S for rotating the inner cylinder 71 integrally with the outer cylinder 72 can be achieved. As a result, the lock box 62 can be moved to the unlocked position from the locking position force, and the storage box 60A can be opened and closed.

[0092] Therefore, if the lockable storage 60 of the second embodiment is adopted for all the storages in the office, all the storages in the office can be obtained only by possessing the same electronic key 19A. If the person has the right authority for all storage boxes, he / she can open and close the storage box and access the documents in the storage box. Even if multiple people use it, the contact IC tag 5 built into the electronic key 19A authenticates the individual and confirms the access right to the storage box based on the authenticated data. Thus, the user can open and close a large number of storage boxes required by one electronic key 19A while preventing opening and closing by a person without access right. .

[0093] In addition, since the electronic key 19A inserted into the key hole 71a of the lock 70 is rotated to rotate the outer cylinder 72 and the inner cylinder 71 integrally and perform unlocking by human power, an electric lock is not required. It is also possible to keep costs low. The shape of the insertion part 21 of the electronic key 19A is that all the electronic keys have the same rectangular parallelepiped shape, so that all the electronic keys 19A match all the locks 70. All locks 70 can be rotated. However, since all the lock 70 is provided with a solenoid 76 that prevents the rotation of the outer cylinder 72, the rod 77 of the solenoid 76 is removed from the rotation prevention hole 72e of the outer cylinder 72 and the outer cylinder 76 is rotated. The storage box can be opened only when the blocking state is released.

[0094] Information Power of Contact-Type IC Tag 5 Built in Holding Unit 22 of Electronic Key 19A Data Reading Board 75 that Contact Terminal Boards 3 and 4 When Inserting Part 21 of Electronic Key 19A is Inserted into Keyhole 71a , 75 based on the data read by the data reading means 75, 75, authority authentication of the storage box provided with the data reading board 75, 75 is performed, and the lock control is performed when it is determined that the authority is valid. The means 40 causes the solenoid 76 corresponding to the data reading boards 75 and 75 that have read the data to release the rotation preventing state of the outer cylinder 72 so that the inner cylinder 71 can rotate integrally with the outer cylinder 72. The electronic key 19A has a contact IC tag 5 built in the gripping part 22 and the terminal plates 3 and 4 of the contact IC tag 5 are arranged in the insertion part 21, so that the contact key IC tag 5 As well as providing protection, the data reading board 75, 75 can be installed inside the lock 70, so the data reading board cannot be touched from the outside, and V cannot be tampered with.

[0096] Further, since the lock control means 40 stores the opening / closing history for each storage box, it is possible to record all accesses and to open / close all storage boxes in all storages. You can leave a history.

[0097] Further, since the lock 70 can be exchanged with an existing lock, only the lock portion of the existing storage has to be replaced. Therefore, the lockable storage of the second embodiment can be adopted at low cost. Is possible. In particular, since the lock 70 is unitized, it can be easily attached later.When it is determined that the authority is valid based on the access right of the electronic key 19A, the solenoid 76 is driven by an electronic signal. Thus, since the lock plate 62 permits the locking position force to move to the unlocked position, the lock plate 62 can be easily unlocked.

[0098] Further, by storing data for performing authority authentication in the lock control means 40, it becomes possible to perform authority authentication without connecting the lockable storage 60 to a host device via a network or the like. Therefore, the labor and time for wiring work for connecting the lockable storage 60 to the host device can be saved, and the installation cost of the lockable storage can be reduced. If the lock control means 40 is connected to a separately installed authentication means via the network and the authority is authenticated based on the data stored in the authentication device, the authority authentication is performed. Data corruption can be prevented.

By the way, in an emergency such as a power failure, the data reading boards 75 and 75 cannot read the access right from the electronic key 19A, and the storage box cannot be opened / closed using the electronic key 19A. Even in this case, if a suitable emergency key is inserted into the key hole 71a of the lock 70, the inner cylinder 71 can be rotated to move the lock plate 62 from the locked position to the unlocked position, thereby opening / closing the storage box S. Since the emergency key is not fitted into the fitting groove 72d when inserted into the key hole 71a, only the inner cylinder 71 can be rotated. [0100] [Third Embodiment]

Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 12 is an enlarged cross-sectional view of the main part of the lockable storage 90 according to the third embodiment of the present invention, and shows a cover closed state. FIG. 13 is an enlarged cross-sectional view of the main part of the lockable storage 90, showing a cover open state. Note that the lock 100 shown in FIGS. 12 and 13 (an example of “opening / closing permission means” and “moving means”) is connected to the inner cylinder 72 by the lock plate 62 in the same manner as in the second embodiment. Locking is performed by engaging with the Iku 63 (see Fig. 7), but the description of the mouth plate 62 and the strike 63 is omitted to make the drawing easier to see.

The lockable storage 90 of the third embodiment is mainly different from the second embodiment in that the opening / closing of the opening / closing door 92 is permitted by a cover 98 that covers the opening / closing lever 94. Therefore, here, the points different from the second embodiment will be mainly described, and the points common to the second embodiment will be denoted by the same reference numerals, and description thereof will be omitted as appropriate.

[0101] <Configuration of lockable storage>

The lockable storage 90 of the third embodiment is a locker in which an open / close door 92 is rotatably attached to the openings of a plurality of storage boxes provided in the main body 91 by a single opening method. The opening / closing door 92 has a recess 92a. An opening / closing lever 94 is rotatably attached to the recess 92a via a hinge 95. A latch member 93 that engages with a strike 91 a provided on the main body 91 is connected to the opening / closing lever 94. The latch member 93 is urged by a spring (not shown) in a direction protruding from the opening / closing door 92. When the opening / closing lever 94 is rotated in the direction to lift the opening / closing door 92 from the hinge 95, the latch member 93 resists the spring (not shown). It is configured to be drawn into the open / close door 92.

[0102] <Cover configuration>

A cover 98 is slidably provided in the recess 92a. The cover 98 is made of a metal plate, transparent plastic or the like. A motor 96 is fixed to the back side of the opening / closing door 92 with screws or the like. The motor 96 is arranged so as to reciprocate the drive shaft 97 linearly along the sliding direction of the cover 98. The drive shaft 97 is loaded into the motor 96 so that the motor 96 is pulled into the motor 96 when the motor 96 rotates in a predetermined direction, and the motor 96 protrudes from the motor 96 rotating in the direction opposite to the predetermined direction. The tip of the drive shaft 97 has a force Bar 98 is fixed.

As shown in FIG. 12, the cover 98 covers the open / close lever ₉₄ and prevents the open / close lever ₉₄ from rotating and prevents the open / close door 92 from being opened and closed, as shown in FIG. Thus, the opening / closing lever 94 is opened to the outside to allow the opening / closing lever 94 to rotate and to be opened and closed to allow the opening / closing door 92 to be opened and closed.

The cover 98 and the motor 96 constitute “open / close permission means”.

[0104] <Lock configuration>

A lock 100 is attached to the lower side of the opening / closing lever 94. The lock 100 has the same configuration as the lock 70 of the second embodiment, except that the outer cylinder 101 is fixed to the open / close door 92 and does not rotate. The inner cylinder 71 is configured such that when a connecting member (not shown) connected to the cover 98 is screwed to the rear end surface and rotated with respect to the outer cylinder 101, the cover 98 is slid through the connecting member (not shown). Les.

[0105] <Controlled configuration of lockable storage>

FIG. 14 is a block diagram showing a control configuration of the lockable storage.

The cover open / close control means 102 includes all locks 100A, 100B, 100C ... data reading boards 75A, 75B, 75C ..., motors 96A, 96B, 96C ..., ED64A attached to each storage box of the lockable storage. , 64B, 64C… It is connected with a spring. The kanokoku opening / closing control means 102 controls the amount of rotation and the direction of rotation of the motors 96A, 96B, 96C, etc., by the drive signal output to the motors 96A, 96B, 96C,.

[0106] <Description of operation>

In the lockable storage 90 of the third embodiment, when the user inserts the electronic key 19A into the key hole 71a, the cover opening / closing control means 102 is based on the access right that the data reading board 75 reads from the contact IC tag 5. To determine whether the authority is valid. If the cover opening / closing control means 102 determines that the authority is valid, it outputs a drive signal to the motor 96.

When the drive signal is input, the motor 96 pulls the drive shaft 97 and slides the force bar 98 to the open position as shown in FIG. As a result, the opening / closing lever 94 is exposed to the outside, so that the user lifts and rotates the opening / closing lever 94 with the hinge 95 as a base, thereby releasing the engagement between the latch member 93 and the strike 91a and opening / closing. Door 92 can be opened. After that, when the user closes the open / close door 92 so that the latch member 93 is engaged with the strike 91a and removes the electronic key 19A from the key hole 71a, the cover open / close control means 102 is driven by the motor 96. Output a signal. When the drive signal is input, the motor 96 moves the drive shaft 97 in a direction approaching the cover 98, and places the cover 98 at the covering position. As a result, the opening / closing lever 94 is covered with the cover 98, and the user cannot turn the opening / closing lever 94 by placing a finger on the opening / closing lever 94. That is, the user cannot open the door 92.

The cover opening / closing control means 102, when the electronic key 19A is removed from the key hole 71a, the usage history of the storage box (unlocking time, locking time, personal ID of the user, identification number of the electronic key 19A). Etc.) are stored in RAM42.

[0110] On the other hand, if the cover opening / closing control means 102 determines that the authority is not valid based on the access right stored in the electronic key 19A, the cover opening / closing control means 102 does not give a drive signal to the motor 96, Leave it in the covering position. Therefore, the user cannot open the door 92 by operating the opening / closing lever 94.

[0111] By the way, in case of an emergency such as a power failure, if the emergency key is inserted into the keyhole 71a and the inner cylinder 71 is rotated with respect to the outer cylinder 101, the cover 98 is moved to the open position and the open / close lever 94 is operated. You will be able to do it.

[0112] <Effects of lockable storage according to the third embodiment>

Therefore, the lockable storage 90 according to the third embodiment covers the opening / closing lever 94 with the cover 98 to restrict the operation of the opening / closing lever 94 so that the storage box cannot be opened / closed. Then, when it is determined that the authority is valid based on the access right read by the data reading board 75, 75 from the electronic key 19A, the cover 98 can be moved from the covering position to the open position. As a result, the storage box can be opened and closed by moving the cover 98 to the open position and operating the open / close lever 94.

[0113] With this, if the storage 90 of the third embodiment is adopted for all the storages in the office, all the storages in the office can be obtained only by possessing the same electronic key 19A. If the person has a legitimate authority to the storage box, the storage box can be opened and closed to access the documents in the storage box. Even if multiple people use it, The contact IC tag 5 built in the key 19A authenticates the individual, confirms the access right to the storage box based on the authenticated data, and controls the open / closed state of the storage box. Therefore, the user can open and close many storage boxes required by one electronic key 19A while preventing opening and closing by a person without access right.

[0114] The electronic key 19A is provided by the data reading boards 75 and 75 that come into contact with the terminal plates 3 and 4 when the information insertion portion 21 of the contact IC tag 5 built in the grip portion 22 is inserted into the key hole 71a. Based on the data read and read by the data reading boards 75, 75, the right of the storage box provided with the data reading boards 75, 75 is authenticated, and when it is determined that the right is valid, the cover opening / closing control means 102 However, the cover 98 can be moved.

[0115] In addition, since the lockable storage 90 has a storage means for storing the opening / closing history for each storage box, it is possible to record all accesses, and all the storages of all storages are stored. A history of opening and closing can be kept for the storage box.

[0116] In addition, by storing data for performing authority authentication in the cover opening / closing control means 102, it is possible to perform authority authentication without connecting the lockable storage 90 to a host device via a network or the like. Therefore, the labor and time for wiring work for connecting the lockable storage 90 to the host device can be saved, and the installation cost of the lockable storage can be reduced. On the other hand, if the cover open / close control means 102 is connected to a separately installed authentication means via a network and the authority is authenticated based on the data stored in the authentication device, the authority authentication is performed. Data can be prevented from being damaged.

[0117] By the way, in the event of an emergency such as a power failure, the data reading boards 75 and 75 cannot read the access right from the electronic key 19A, and the storage box cannot be opened and closed using the electronic key 19A. Even in this case, if a suitable emergency key is inserted into the key hole 71a of the lock 100, the inner cylinder 71 is rotated, the cover 98 is moved from the covering position to the open position, and the storage box can be opened and closed.

Furthermore, the lock 100 locks the opening / closing door 92 by a lock plate 62 (see FIG. 7) connected to the inner cylinder 71, and rotates the inner cylinder 71 to unlock the opening / closing door 92. Therefore, the lockable storage 90 has a high security level because the lock box 62 (see Fig. 7) and the cover 98 restrict double opening and closing of the storage box. [Fourth Embodiment]

Subsequently, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 15 is a partially enlarged front view of the lockable storage 115 according to the fourth embodiment of the present invention.

The lockable storage box 115 of the fourth embodiment is different from the second embodiment in that the lock plate 120 (an example of “locking means”) is automatically rotated. Therefore, here, the difference from the second embodiment will be mainly described, and the points common to the second embodiment will be denoted by the same reference numerals as those of the second embodiment, and description thereof will be omitted as appropriate.

[0120] <Structure of lock>

In the lock 110 (an example of “open / close permission means” and “moving means”), the outer cylinder 111 is fixed to the open / close door 61B and does not rotate. An inner cylinder 71 is rotatably held by the outer cylinder 111. The lock 110 is screwed to the rear end face of the connecting member inner cylinder 71 (not shown) connected to the lock plate 120, and the lock plate 120 can be rotated by rotating the inner cylinder 71. .

[0121] The lock plate 120 has a guide groove 120a. A pin 122 erected on the operating shaft 121 is slidably passed through the guide groove 120a. A rack portion 121a is formed at the upper end of the operating shaft 121, and a pinion 125 that is connected to a rotating shaft 124 of a motor 123 (an example of “moving means” and “rotation preventing means”) is connected.

[0122] <Controlled configuration of lockable storage>

FIG. 16 is a block diagram showing a control configuration of the lockable storage.

The lock control means 40 includes all the lock 11A, HOB, 110C data reading boards 75A, 75B, 75C ..., motors 123A, 123B, 1230 ..., LED64A attached to each storage box of the lockable storage. , 64B, 64C… It is connected with the power fountain. The pre-control unit 40 outputs a drive signal for controlling the rotation amount and the rotation direction to the motors 123A, 123B, 123C, and so on, and positions the lock plate 120.

[0123] <Description of operation>

When the lock control means 40 authenticates the legitimate authority based on the access right read by the data reading board 75 from the electronic key 19A inserted into the key hole 71a, the lock storage unit 115 of the fourth embodiment is used. A drive signal is output to. The mode in which the drive signal is input The data 123 rotates the rotating shaft 124 in a predetermined direction. The rotating shaft 124 rotates integrally with the pinion 125 mated with the rack portion 121a, and moves the operating shaft 121 downward in the figure. The operating shaft 121 rotates the lock plate 120 clockwise through the pin 122 via the pin 122 and rotates the lock plate 120 to the unlocked position. As a result, the lock plate 120 is disengaged from the strike 91a, and the opening and closing of the doors 61A and 61B is permitted.

[0124] When the user closes the open / close doors 61A and 61B and removes the electronic key 19A from the key hole 71a, the lock control means 40 outputs a drive signal to the motor 123. When the drive signal is input, the motor 123 rotates the rotating shaft 124 in the direction opposite to the predetermined direction. The pinion 125 rotates integrally with the rotating shaft 124 and moves the operating shaft 121 upward in the figure via the rack portion 121a. The operating shaft 121 rotates the lock plate 120 counterclockwise in the drawing via the pin 122 and arranges it at the locking position. As a result, the lock plate 120 engages with the strike 63 and restricts the opening and closing of the doors 61A and 61B.

Incidentally, even in an emergency such as a power failure, the inner cylinder 71 can be rotated with respect to the outer cylinder 111 by inserting an emergency key that fits into the key hole 71a into the key hole 71a. The inner cylinder 71 can move the lock plate 120 between a locked position and an unlocked position by rotating the lock plate 120 via a connecting member (not shown).

[0126] <Effects of lockable storage according to the fourth embodiment>

In the lockable storage 115 according to the fourth embodiment, the pin 122 of the operating shaft 121 is fitted to the upper end of the guide groove 120a of the lock plate 120, the lock plate 120 is engaged with the strike 63, and the door 61B is opened. Arranged at the locking position to lock. When the motor 123 rotates in a predetermined direction, the rotational force is converted into thrust when it is transmitted from the pinion 125 to the rack portion 121a, and the operating shaft 121 is moved downward. As the operating shaft 121 is lowered, the pin 122 slides along the guide groove 120a toward the lower end, and rotates so that the lock plate 120 stands. Eventually, the lock plate 120 disengages from the strike 63 and is placed in the unlocked position. Then, when the motor 123 rotates in the direction opposite to the predetermined direction, the operating shaft 121 starts to move upward in the reverse manner to the above. As the operating shaft 121 rises, the pin 122 moves from the lower end portion of the guide groove 120a toward the upper end portion and rotates the lock plate 120 so as to be tilted sideways. Eventually, the lock plate 120 engages with the strike 63 and locks the door 61B. As described above, the lockable storage 115 according to the third embodiment directly locks the lock plate 120 at the locking position using the driving force of the motor 123. Therefore, when the data reading board 75, 75 determines that the authority is valid based on the access right read from the electronic key 19A, it outputs a drive signal that rotates in a predetermined direction to the motor 123 corresponding to the access right, Release the locked state of lock plate 120. As a result, the lock plate is automatically moved to the unlocking position from the locking position force, and the storage box can be opened and closed.

[0128] Since the lockable storage 115 is locked and unlocked by the force of the motor 123, the user can unlock the storage box without turning the electronic key 19A, which is convenient. Further, since the inner cylinder 71 is rotated by the force of the motor 123, the lock 110 does not apply excessive force to the inner cylinder 71 and the outer cylinder 111 and is not easily damaged.

Note that the present invention is not limited to the above-described embodiments, and may be implemented as follows by appropriately changing a part of the configuration without departing from the spirit of the invention. In this embodiment, a force wireless IC tag using a contact IC tag may be used. However, with wireless IC tags, if many wireless IC tags are used in a close range, crosstalk problems will occur. Contact IC tags are superior in that they do not cause crosstalk. When using a wireless Ic tag, the storage box should be locked and unlocked with a switch. In this case, if the locking switch is not pressed even after a few seconds have passed since the storage box is closed, a buzzer sound or a message is emitted from the alarm means to notify the user that the electronic key has been forgotten to be removed. May be.

In addition, for example, in this embodiment, data for authority authentication is stored in the RAM 42 inside the lock control means 40, but the personal authentication data is connected to the lock control means via a network. 44 may be stored. Further, data for authority authentication may be stored in both the lock control means 40 and the personal computer 44.

Normally, the authority authentication data is rewritten on the personal computer 44, so the data on the personal computer 44 is up-to-date and should be managed accordingly. On the other hand, when the PC 44 is down, it is a problem that the materials in the lockable storage cannot be viewed at all. If the means 40 has authority data, it can be viewed.

[0130] Further, for example, in this embodiment, the electronic key 19 may be connected by a force adhesive that uses a screw, or by laser welding. Further, the terminal boards 3 and 4 may be inserted and integrally molded, and only the contact type IC tag 5 may be retrofitted. That is, since the contact type IC tag 5 is vulnerable to heat or the like, it is technically difficult to insert-mold the contact type IC tag 5, so as shown in FIG. The lid may be fixed by ultrasonic welding or the like in a state where is adhered to the back surface of the lid 6. In FIG. 17, transparent resin is used for the key boards 1 and 2, so that the terminal boards 3 and 4 can be seen through.

In the present embodiment, the lock attached to the storage box of the storage is disclosed from the beginning, but the lock may be replaced with an existing lock.

In this embodiment, the lock control device 40 can control more storages than the force that controls the three storages.

[0131] Further, in the above embodiment, the force bearing 80 and the solenoid 76 obtained by unitizing the lock 70 may be directly attached to the storage box.

Further, in the above-described four embodiments, the force inner cylinder 71 in which the lock plate 120 is connected to the inner cylinder 71 and the mouth plate 120 may be provided separately. In this case, locking and unlocking can be performed without turning the electronic key 71a inserted into the key hole 71a, and damage to the lock 110 can be further prevented.

In the third embodiment, the cover 98 is automatically opened and closed by the motor 96. On the other hand, a slide prevention mechanism that locks the cover 98 in the locked position to prevent the cover 98 from sliding is provided in the lockable storage 90, and when the authorization is authenticated, the slide prevention state by the slide prevention mechanism is released. The cover 98 may be manually moved between the covering position and the unlocking position.

In the above embodiment, double personal authentication is performed based on the encryption number input to the numeric keypad operation unit 33 and the contact IC tag of the electronic key, and the storage box is opened and closed only when the authority is valid. Admitted. On the other hand, if the authority authentication is performed only based on the contact IC tag of the electronic key, the device cost can be reduced by omitting the numeric keypad operation unit 33. In the second embodiment, the solenoid 76 is arranged in a direction orthogonal to the axis of the inner cylinder 71. On the other hand, a projection provided with an engagement hole that engages with the rod 77 of the solenoid 76 is provided on the solenoid 76 so that the axial centers of the inner cylinder 71 and the solenoid 76 are flat fi, and the outer circumference of the outer cylinder 72 The outer cylinder 72 may be prevented from rotating by being attached to the surface. According to this, the installation space for the lock including the solenoid 76 can be reduced.

In the second embodiment, when the electronic key 19A is provided with a locking part such as a recess in the insertion part 8lb of the electronic key 19A and personal authentication is performed based on the electronic key 19A before opening the doors 61A and 61B. In addition, the lock 70 may be provided with an attaching / detaching restricting means for engaging with the locking portion and restricting the attaching / detaching of the electronic key 19A. In this case, the electronic key 19A can be attached to and detached from the lock 70 only when the doors 61A and 61B are closed, so the electronic key 19A cannot be removed from the lock 70 with the doors 61A and 61B open! /.
