Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a synthetic resin key and a door locking / unlocking mechanism using the key.

[0002]

[Prior art]

 Recently, in the keyless era, for example, as described in Japanese Patent Application Laid-Open No. 2-47480, a ten key provided on a keyboard is operated based on a personal identification number to unlock an electric lock. In addition, by using a so-called "card key" that creates multiple circuits on the surface or inside the semiconductor chip and encloses the combination of resonance frequencies based on these circuits in the card, the electrical contactless door is installed on the door. A locking / unlocking mechanism has emerged in which the locking means of the lock is unlocked.

In the former case, a metal key is always carried so that the electric lock can be unlocked manually, but generally, the metal key is about 10 grams per one, which is a daily life. Since it is common to carry around 2 to 5 keys with other metal keys in a pocket or the like, in a sense, it is heavy and inconvenient if the number of metal keys increases. If the electric lock does not work due to a power failure, control device failure, etc., or if you do not have a metal key for the electric lock on the spot for any reason, always manage it. There are no people, so it can be very troublesome.

On the other hand, in the latter case, although it is convenient to not necessarily have a metal key, the locking / unlocking mechanism does not operate due to a power failure, controller failure, or the like. In some cases, the "card key" cannot unlock the electric lock, which is a drawback.

[Problems to be solved by the device]

 In view of the above-mentioned conventional drawbacks, the present invention takes into consideration an emergency case, and even if it is always carried as a spare key, it does not burden the user much, and the electricity provided on the door is non-contact type. A synthetic resin that can be used to unlock the locking means of the lock and to unlock the electric lock even if the locking and unlocking mechanism does not work due to a power failure, controller failure, etc. The key is to obtain a key made by the manufacturer and a locking / unlocking mechanism for the door using this key.

[0006]

[Means for Solving the Problems]

[Action]

 The door locking / unlocking mechanism will be described. For example, when the key is brought close to the electromagnetic wave transmission detection means, a magnetic field is always generated around the transmission coil of the electromagnetic wave transmission detection means on the device or mechanism side, so that a current flows in the reception coil on the key side. The current is stored in the charger through the rectifier. When the voltage of the charger reaches a predetermined voltage, the code generation circuit operates and the switch operates according to the information fixed in the ROM. The current fluctuates depending on the ON / OFF state of this switch, and the electromagnetic induction as a pulse causes a pulse to be generated on the electromagnetic wave transmission detection means side. This pulse is sent to the detector of the control device on the device or mechanism side.

Therefore, based on the judgment of the judgment unit, the central processing unit CPU sends the collation signal to the switch circuit only when the stored information previously registered in the storage unit matches the input signal from the detection unit. . Then, the electric lock is released.

On the other hand, when the locking / unlocking mechanism does not operate electrically, the key is inserted into the key hole of the electric lock and the electric lock is manually unlocked.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

First, FIGS. 1 and 2 show a synthetic resin key X of the first embodiment. This key X does not have a battery and has an electromagnetic wave ID chip 3 in the picking section 1 which receives and responds to the specific frequency 2 transmitted from the transmitting section of the electromagnetic wave transmission detecting means 13 from the air. The electromagnetic wave ID chip 3 is a circuit in which multiple circuits are generated on the surface or inside of a semiconductor material or an insulating material. It uses energy received from the air at a certain specific unlocking frequency. When the voltage of the charger provided in the device reaches a predetermined voltage, the cipher generation circuit operates and the switch operates according to the information fixed in the ROM.

That is, the electromagnetic wave ID chip 3 of the key X has a receiving coil 3 a that causes the electromagnetic induction 20 together with the transmitting coil 13 a that constitutes a part of the electromagnetic wave transmission detecting means 13. Further, the circuit has a rectifier 3b and a charger 3c. The charger 3c is connected to a code generation circuit 3e for turning on / off the switch 3d.

In such a configuration, since the magnetic field is constantly generated around the transmission coil 13a of the electromagnetic wave transmission detection means 13 on the device or mechanism side, when the key X approaches the electromagnetic wave transmission detection means 13. , A current flows through the receiving coil 3a on the key X side. The current is stored in the charger 3c through the rectifier 3b.

When the voltage of the charger 3c reaches a predetermined pressure, the cipher generation circuit 3e operates and the switch 3d operates according to the information fixed in R OM. The current fluctuates due to ON / OFF of this switch, and the electromagnetic induction 20 forming a pulse causes the electromagnetic wave transmission detecting means 13 side to generate a pulse by itself. The electromagnetic wave ID chip 3 having such a function is built in the knob portion 1 of the key X in this embodiment. However, the electromagnetic wave ID chip 3 does not necessarily have to be built in the picking section 1, and it may be fixedly embedded in the recess of the picking section 1, attached to the picking section 1, or even in the picking section 1. You may attach it appropriately, such as covering it or hanging it.

Reference numeral 4 denotes an insertion portion that is connected to the knob portion 1. The insertion portion 4 has a form similar to that of a general metal key, and an electric lock provided on a door can be manually unlocked. Next, FIG. 3 and FIG. 4 show a synthetic resin key X1 of the second embodiment. This key X1 has an electromagnetic wave ID chip 3A that receives and responds to a specific frequency 2A from the air, and a key body 5 made of synthetic resin capable of manually unlocking the electric lock provided on the door. And a seat integrated with the key body 5 through a plurality of small connecting portions 7 that can be detached or bent and bent, and a storage portion 6 that can store the key body 5 in the same plane. 8 and a reception response antenna coil 3B provided on the seat 8 so as to be located around the key body 5. In this embodiment, the storage section 6 is not always necessary. The point is that the seat 8 and the key body 5 should be on the same plane.

With such a configuration, the key X1 becomes a card shape, and can be put in a notebook, wallet, etc. in advance and always carried, and the reception response antenna coil 3B is separated from the electromagnetic wave ID chip 3A of the key X1. Since it is added, the distance from the electromagnetic wave transmission detection means on the device or mechanism side may be increased to some extent.

Next, FIG. 5 shows a door locking / unlocking mechanism using the keys X and X1 made of the synthetic resin. In this embodiment, a door locking / unlocking mechanism Y using a key X will be described for convenience.

The door locking / unlocking mechanism Y has the electromagnetic wave ID chip 3 described above that receives and responds to the specific frequency 2 from the air, and the electric lock provided at the opening / closing end of the door 10. A key X made of a hard synthetic resin that allows the locking means 12 of the air lock 11 to be manually unlocked, and the key X is provided in the door 10 and has a transmission coil 13a, and the key X is within the sensor area. When entering the electromagnetic wave ID chip 3, the electromagnetic wave transmission detecting means 13 which itself generates a pulse by electromagnetic induction which becomes a pulse which responds, and the detecting portion 13c receives the detection (pulse) signal from the electromagnetic wave transmission detecting means 13. When it is determined that the stored information and the detection signal match with each other through the determination unit 15 that compares and compares the stored information previously registered in the storage unit 14 with the detection signal. From a combination of a control device 17 which sends a verification signal to the switch circuit 16 and the electric lock 13 which is electrically connected to the control device 17 and which causes the locking means 12 to be unlocked based on the verification signal. Become. Reference numeral 18 is a connector, and 19 is a conductive metal fitting having a hinge function.

Therefore, the electromagnetic wave transmission detecting means 13 is a ferrite structure (so-called antenna / reader) and has a function of transmitting / detecting a wave motion to the key X. The control device 17 is formed on a printed circuit board and has a central processing unit CPU. Furthermore, the electric lock 11 is connected to a solenoid via a driving transistor, and its specific configuration is already known.

In the above configuration, a magnetic field is always generated around the transmission coil 13a of the electromagnetic wave transmission detection means on the device or mechanism side, and a specific frequency is continuously transmitted from the transmission unit 13b. Therefore, when the key X is brought close to the transmission coil 13a of the electromagnetic wave transmission detection means 13, a current flows in the reception coil 3a on the key X side. The current is stored in the charger 3c through the rectifier 3b. Then, when the voltage of the charger reaches a predetermined voltage, the code generation circuit 3e operates and the switch 3d operates according to the information fixed in the ROM. A current fluctuates due to ON / OFF of the switch 3d, and a pulse is generated on the electromagnetic wave transmission detection means 13 side by the electromagnetic induction 20 which becomes a pulse. This pulse (detection signal) is sent to the detection unit (information receiving unit) 13c of the control device 17 on the device or mechanism side.

Therefore, the central processing unit CPU sends the collation signal to the switch circuit 16 only when the stored information previously registered in the storage unit 14 and the input signal match based on the collation or the determination of the determination unit 15. Then, the locking means 12 of the electric lock 11 is unlocked.

On the other hand, if the locking / unlocking mechanism does not work due to a power failure, control device failure, etc., the insertion portion 4 of the key X is inserted into the key hole of the cylinder of the electric lock 11, and the key is made of metal. Similarly, the electric lock 11 is manually unlocked.

[0025]

[Effect of device]

 As is clear from the above description, in the present invention, the key is formed by using a synthetic resin material, which allows the detection distance to be longer than that of a metal key, and also reduces the weight of the key. Can be planned.

Therefore, even if the user always possesses a synthetic resin key as a spare key, it will not be a burden, and even if the synthetic resin key is brought close to the electromagnetic wave transmission detection means 13 of the door, the key itself will be released. There is no obstacle, and the locking means 12 of the electric lock 11 provided on the door 10 can be unlocked through the control device, and the locking / unlocking mechanism is not activated due to a power failure, a failure of the control device, or the like. Even when the electric lock 11 is not electrically operated, the key insertion portion can be inserted into the key hole of the electric lock 11 to manually unlock.

The key X1 has an electromagnetic wave ID chip 3A for receiving and responding to a specific frequency 2A from the air, and is made of a synthetic resin capable of manually unlocking an electric lock provided on the door. Has a key body 5 and a storage portion 6 that can store the key body 5 in the same plane, and is integrated with the key body 5 through a plurality of small connecting portions 7 that can be detached or bent and raised. In the embodiment including the converted sheet 8 and the reception response antenna coil 3B provided on the sheet 8 so as to be located around the key body 5, the detection distance is further extended as compared with the case of the key X. .
