Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system and a method for locking a building, and is particularly preferably used in an apartment house such as a condominium.

[0002]

2. Description of the Related Art Conventionally, in a collective housing such as a condominium, not only is each room locked, but also the doorway in the building is locked. Specifically, doors such as automatic doors installed at the entrances and exits of buildings are normally locked and can be easily released from inside (without any authentication), but when entering inside from outside Has a locking system that requires some kind of authentication.

This locking system has a door in a normally locked state and a lock releasing means for transmitting a lock release request signal for releasing the locked state of the door. The lock releasing means is a fixed condition. Under the circumstances, it is provided to transmit a lock release request signal. The conditions for transmitting this lock release request signal are when the key of the resident's room matches, and when a lock release request is received from each room in response to the intercom whose room number is entered using the numeric keypad. Further, the lock release means transmits a lock release request signal to the door. For this reason, it has a certain effect in preventing suspicious persons from entering the building. In particular, in the case where a post for postal matter is provided inside the door in the locked state, the posting of advertisements and the like is reduced and the appearance of the condominium is excellent.

In addition, in the conventional locking system, the personal identification number (a number different from the room number) even under conditions other than those mentioned above.
Is input by the ten-key pad of the external intercom, the lock release means transmits a lock release signal to release the locked state of the door. this is,
This is because, for example, such a personal identification number is necessary when a firefighter or the like enters the building urgently in the event of a fire in a condominium, and this is taken into consideration. In the present situation, the apartment manager (owner) is informed of the personal identification number by the condominium manager (owner). In other words, it is used by the applicant for a rental contract to enter the apartment when he / she visits the renter.

However, the inventor was concerned about the harmful effects of informing a plurality of persons of the personal identification number. That is, if the personal identification number becomes known to an unspecified large number, the function of the locking system will be lost. If such a situation occurs, intrusion of suspicious persons below a certain level can be eliminated to some extent, but it is essential that advertising materials are scattered on the floor and spoil the aesthetics of the apartment.

[0006] In order to prevent this, a method of changing the personal identification number in a short term (for example, every month) can be considered.
However, this is extremely complicated work for the condominium manager.

[0007] In addition, it is conceivable to adopt a method of not letting anyone (even if it is a renter) know the personal identification number, except when there is an emergency. However, then the renter would have to go to the apartment manager to rent the key. this is,
It doesn't matter if the condominium manager is always near the condominium (or the renter), but if not, the renter (along with the applicant for the renting contract) has It is necessary to go to the original site, which is extremely complicated work for the renter and the applicant for a rental contract. For this reason, there is a risk that the occupancy rate of the condominium will be reduced. In particular, in the current situation, the condominium manager is located far from the location of the condominium, and often requests a renter near the condominium location to rent the condominium.
The above problem is even more so.

[0008]
