DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock system for locking and unlocking a lock device using a key, and particularly relates to a user and an object to be used in a state before use, such as a rental bicycle or a locker of a membership facility. The present invention relates to a lock system suitably used for locking and unlocking in a mode in which a fixed relationship is not provided between the lock system and the lock system.

[0002]

2. Description of the Related Art In recent years, electronic locks have tended to be used in place of conventional cylinder locks as lock systems for doors and lockers in hotels, various membership facilities, and the like. The basic structure of this electronic lock is, for example, as disclosed in Japanese Patent Laid-Open No. 5-179847, an IC with a built-in semiconductor IC memory chip in which an individual identification code is stored in a key for locking and unlocking.
A card or a magnetic card is used (hereinafter, these are referred to as “card keys”), and the electronic key is recognized by contacting or non-contact with a card reader of the electronic lock. As a result of reading the code and comparing it with the identification code preset for the electronic lock,
If the codes match, the lock mechanism of the electronic lock is released, and if they do not match, the locked state is maintained.

When a user loses a key in a lock system using the above-mentioned card key and electronic lock, the card key to which the identification code is added is reissued or information inside the electronic lock is rewritten to re-issue the key. It is easy to reconfigure and does not need to replace the entire lock device as in conventional mechanical locking systems. Further, the lock system using the card key and the electronic lock is more advantageous than the mechanical type in terms of security, for example, because it is difficult to forge the card key.

[0004]

When a locker or the like provided with the electronic lock is used, a user is given a specific card key having the identification code in advance, and the identification code of the card key is assigned to the user. You will use the specific locker that corresponds. Therefore, it is necessary for the facility to manage or issue a card key corresponding to each locker, and the user can select his / her favorite locker from the viewpoint of location, size, etc. and freely use it. There was a disadvantage that it could not be used.

The present invention has been made in view of the above situation, and there is no need to manage keys corresponding to each lock device.
The user uses a specific key distributed in advance or the like to select a desired locker from an unspecified number of lockers and the like, and provides a lock system that can lock and unlock the locker.

[0006]

The inventor of the present invention has made intensive studies to solve the above-mentioned problems. As a result, a lock device that accepts a certain unspecified number of keys, when locking, receives information unique to the received key. And constructing a lock system for discriminating the suitability of unlocking by comparing and verifying the information unique to the received key with the already stored information at the time of unlocking when unlocking. Thus, after the user freely selects a favorite locker or the like, the user can securely lock the locker using a specific key owned by the user, and since there is no key unique to the lock device, each key can be locked. The inventor has found that the trouble of managing or issuing each key can be saved, and the present invention has been completed.

That is, the present invention has a key and a lock device for receiving and unlocking the key.
A storage means is provided for storing at least one of the unique information and storing information having a unique relationship with the received unique information, and the lock device accepts a key in an unlocked state, and Performs locking, and a lock mode in which information having a unique relationship with the unique information is stored in the storage means, and a lock mode in which the lock device receives the key in the locked state and the unique information and the information stored in the storage means. An unlocking mode in which the lock device unlocks when a unique relationship is established between them and the information stored in the storage means is erased. I do. Here, the lock device accepts the key, that is, not only does the lock device actually wrap the key in a contact or non-contact state, but also transmits a wireless signal transmitted from a key at a position away from the lock device. This is a broad concept that also includes reception by the lock device and the like, in which the operation when the user uses the key is mainly expressed by the lock device. In the above lock system, a unique relationship occurs between the key and the lock device from the time when the information is stored in the storage means,
It is impossible to unlock the lock device using another key having no unique relationship, and security is ensured. Further, the lock device is unlocked using the key having the above-mentioned unique relationship, and from the point in time when the information in the storage means is erased, the key can lock any of the unlocked lock devices. The lock device in the locked state is locked using any key. That is, the unique relationship between the key and the lock device is maintained only while the lock device is in the locked state, and the key and the lock device have no relationship in the unlocked state. Therefore, there is no need to manage keys for each lock device, and the user can select and use all unlocked lock devices using a specific key.

Further, the lock device is unlocked using a key having key information having a unique relationship with the lock information stored in the lock storage unit, and from the time when the lock information is deleted, the lock device in the unlocked state is unlocked. Will be locked using any key.

Here, in addition to the above configuration, a use storage unit is provided in which the lock device is provided with device information unique to the device, and a key stores use information having a unique relationship with the device information. When the lock device accepts a key having no use information in the unlocked state, the lock is performed, the use information in which the key has a unique relationship with the device information is stored in the use storage unit, and the lock is performed in the locked state. When the device accepts the key, the lock device determines the relationship between the key information unique to the key and the lock information already stored in the lock storage unit and the use of the key already stored in the use storage unit. The relationship between the information and the device information unique to the lock device is compared and verified, and when a unique relationship is established between the two as a result of the verification, unlocking is performed and the storage of the lock information and the use information is deleted. With locking system Therefore, a key storing use information having a unique relationship with the device information of a specific lock device in a locked state will be rejected when using another lock device, and a plurality of locks will be performed with one key. Use of the device is prevented.

As another example, a key is provided with a use storage unit for storing use information having a unique relationship with device information unique to the lock device, and the lock device is provided with device information unique to the device. Verification means for comparing and verifying the relationship between the use information already stored in the use storage section of the newly accepted key and the device information assigned to the lock device, and an unlocking mechanism, The device locks by accepting the key that has no use information in the unlocked state, stores the use information having a unique relationship with the device information unique to the device in the use storage unit of the key, and stores the key in the locked state. By accepting the key, the relationship between the use information already stored in the use storage unit of the key and the device information assigned to the lock device is compared and verified, and as a result of the verification, a unique relationship is established between the two. When In a lock system for unlocking and erasing the storage of the use information, the key information is stored in the use storage section of the key from the time when the use information having a unique relationship with the device information of the lock device used is stored. A unique relationship arises between the device and the lock device, and other keys having usage information that has no unambiguous relationship with the device information are rejected by the verification means, making it impossible to unlock the lock device and security. While being secured, the key is rejected when using another lock device, and the use of a plurality of lock devices with one key is prevented.
