Description

[Detailed Description of the Invention] The present invention has a structure in which the door is automatically locked when it is closed, and can be opened by operating the knob from inside the door and by verifying a card from outside the door. Related to card type automatic locking device.

Conventionally, in hotels and other facilities, the doors of each guest room are equipped with card-based or other automatic locking devices, but with this type of locking device, customers are unable to open the door without leaving their card or key in the guest room. Problems frequently occur where the door closes and locks automatically, locking people out of the room.

The present invention focuses on the fact that when this type of trouble occurs, most customers realize that they have left behind their cards the moment they close the door, and when they go outside and close the door, the electric lock mechanism is activated for a certain period of time. It is an object of the present invention to provide a card-type automatic locking device that drastically reduces the occurrence of the above-mentioned troubles by unlocking the door and then returning it to the locked state.

The present invention will be specifically described below based on embodiments shown in the drawings.

FIGS. 1 to 3 show the card-type automatic locking device according to the present invention installed on the door of a hotel guest room.

The illustrated door 1 includes knobs 21 and 22 that protrude inwardly and outwardly from the door, and a latch bolt 2 that retracts from the side end surface of the door.
The outer knob 22 is fixed to the door 1, and the inner knob 21 is connected to the latch bolt 2 and rotatably attached to the door 1. The latch bolt 2 has a tapered portion 23 on its outer surface, and therefore easily engages in a latch engagement groove 30 (described later) while retracting, but is prevented from escaping from the groove 30.

A latch engagement groove 30 equipped with an electric locking mechanism 4 is provided on the opening end face of the partition wall 10, and a detection piece 41 of a detection switch for detecting the open/closed state of the door 1 is provided at a lower position of the groove so as to be freely retractable. ing.

Further, a card reader 5 is attached to the outer surface of the wall, and is configured to insert and remove a card into a central card insertion groove 50.

As shown in FIG. 3, the electric lock mechanism 4 includes a lock member 40 disposed in the latch engagement groove 30 and a solenoid (not shown) built in the case 3. This solenoid normally prevents the locking member 40 from moving out (indicated by an arrow in FIG. 3), but is retracted and biased by an unlocking command from the controller 6 to allow the locking member 40 to move out. Therefore, when a force is applied in the direction of opening the door in the unlocked state, the latch bolt 2 pushes the locking member 40 into the latch groove 30.
escape more.

FIG. 4 shows a card 51 for unlocking operation.

A magnetic information recording section 52 is provided on the surface of the card 51, and various information a x e regarding the hotel number, room number, secret number, card issue date, and length of stay are recorded at the front desk when the customer checks in. Ru. The secret number information C is used to prevent card forgery and is updated every time a customer changes.

FIG. 5 shows an example of a circuit configuration implementing the indoor power supply control method according to the present invention.

The card reader 5 reads the card information a-me with a magnetic head and stores it in the buffer memory 6 of the controller 6.
Send to 1. The buffer memory 61 is for temporarily storing read information, and the presence of the stored information allows confirmation that the card 51 has been set in the card reader 5.

The detection switch 42 detects the open/closed state of the door, and turns on/off when the detection piece 41 is released from the pressure. The storage device 62 stores the hotel number to be compared with the card information axe,
Stores data regarding room number, secret number, current date, and length of stay.

FIG. 6 shows the storage area m for these data, and the area r
n1. Each data of a hotel number and a room number is fixedly stored in rn2. Data of a different specific secret number is written in area m3 each time the customer changes. The current date is written in area m4 while being updated daily by the clock mechanism 63. In area m5, the remaining days of stay are at a specific time (for example, hotel check-out time)
is subtracted and written each time . Arithmetic processing unit 64
is used to perform calculations such as determining the authenticity of the card 7 by comparing the card information and the stored data, and sends a signal instructing the unlocking of the electric locking mechanism 4 and its reset signal to the unlocking signal storage circuit 65. Controls the sending operation, etc. In the figure, a drive circuit 43 is a circuit for energizing and deenergizing a solenoid 44 of the electric lock mechanism 4.

FIG. 7 shows the operation flow of the above device.

"Start" in step 81 means that the cabin door 1 is closed, the electric lock mechanism 4 is in the locked state, and the power control circuit 7 is in the locked state.
means that the circuit is open. Therefore, there is no power supply to the various electrical appliances in the room, making them inoperable.

When the customer inserts and sets the card 51 into the card insertion groove (material) of the card reader 5, the card information 3 to e is read by the magnetic head of the card reader 5 and temporarily stored in the buffer memory 61. 82 “
Is there a card input? ” is determined as YES. If the determination at step 82 is No, a "card waiting" state is created around routes 101 and 102.

Next, in step 83, the arithmetic processing unit 64 reads the card information set in the buffer memory 61 and the storage device 6.
The authenticity of the card 51 is determined by reading and collating the data stored in the storage area m of No. 2. In this case, before the new customer enters the room, the storage device 62 stores the private number data of the previous customer, so the comparison result between the card information C regarding the private number and the stored data will be inconsistent. In such a case, the card information d regarding the card issue date and the date data are then compared, and since they match, area m3 of the storage device 62 is rewritten with the new customer's secret number data, and area m.

is the remaining days of the stay, for example, if the stay is 1 night and 2 days, then 1
” will be written.

Therefore, the determination of "Is the card correct?" in step 84 is Y.
ES, and from now on, if the card information regarding the hotel number, room number, and secret number matches the corresponding stored data, and the data regarding the length of stay is not "0", the determination at step 84 will be YES. Become. On the other hand, if a mismatch occurs in any of the items, or if the data regarding the length of stay is "0", the determination at step 84 is NO.

If the determination in step 84 is YES, nokurafu memory 61
The contents of the solenoid 4 of the electric lock mechanism 4 are cleared.
4 is retracted and the locking member 40 is allowed to move out, and becomes electrically "unlocked" (step 85.
86). On the other hand, if the determination in step 84 is NO, the contents of the buffer memory are similarly cleared (step 87
), the electric locking mechanism 4 remains in the locked state and enters a standby state leading to the route 102.

When "unlocked" is selected in step 86, the timer of the clock mechanism 63 starts (step 88), and the electric lock mechanism 4 maintains the unlocked state for a certain period of time, making it possible to open the door 1. .

The length of time is set to a time sufficient for the customer to open the door 1 after setting the card, for example, about 10 seconds. When the customer pushes the door 1 before time-up (determination at step 89 is NO), the long bolt 2 pushes the locking member 40 into the latch engagement groove 30 and escapes from the groove 30, so the door 1 opens and step 90 verdict is YES
becomes. This opening of the door 1 is detected by the door detection switch 42, and the arithmetic processing unit 64 receives this detection signal and returns the electric locking mechanism 4 to the locked state (step 91). In the locked state of step 91, by applying a force in the door opening direction, the latch bolt 2 is retracted by the action of the locking portion 23 and easily engages the large latch groove 30. There is no problem in the closing operation. On the other hand, if the passenger does not open the door 1 before the timer (step 900 judgment power (NO)).

If the judgment in step 8 is YES), the electric port/link mechanism 4 returns to the locked state in step 93, but in this case, the opening operation of the door 1 is no longer possible, and the route 102
It enters a standby state until .

When the customer closes the door 1 after entering the room or without entering the room, the detection switch 42 detects this and the determination in step 93 becomes YES. If the step 93 makes a negative determination, a "door-closed" state is established.

Next, when the guest who entered the room wants to go out, etc., press the inner knob 2.
When the latch bolt 2 is released from the latch engagement groove 30 and the door 1 is opened by rotating the latch bolt 1, the judgment in step 94 is YES.
The result is S, and the process advances to the next step 95. Meanwhile step 93
If a customer closes door 1 without entering the room by entering the room, the customer will not open door 1 by operating the knob 21, so the determination at step 94 will be NO, and the customer will not be able to enter the room via route 102. It becomes a standby state, and it is necessary to open the door 1 using the card.

When the guest goes outside and closes the door 1, the detection switch 42 detects this and the determination in step 95 is YES.
As a result, the electric lock mechanism 4 is unlocked and the timer of the clock mechanism 63 is started (step 96.9).
7). This timer is set to approximately 3 degrees, and the electric lock mechanism 4 remains unlocked during this time period. Therefore, when a passenger pushes the door 1 in the opening direction, the latch bolt 20 pushes the locking member 40 into the latch engagement groove 30 and escapes from the groove 30, and the door 1 opens. Thereby, even if the user forgets the card 51 in the guest room, when the user notices this immediately after closing the door 1, he or she can immediately open the door 1 and return to retrieve the card 51.

Steps 98 and 99 determine whether the door was opened by one force S before time-up, and the determination in step 98 is NOl.
If the determination in step 99 is YES, the door 1 can be opened, and after the time-up, the electric lock mechanism 4 returns to the locked state (step 100). As mentioned above, even if the inner door 1 is electrically locked after opening, there is no problem in closing the door 1. On the other hand, if the door 1 is not opened and the time has elapsed, the determination in step 98 is YES, the determination in step 99 is NO, and the process returns to the locked state in step 100, but in this case, the card 51 is lost and the door 1 is opened from the outside. It is impossible to operate it open.

As described above, when a guest leaves the room and closes the door in a hotel etc., the electric lock mechanism is unlocked for a certain period of time and then returned to the locked state. Even if the card is left behind - when the door is noticed immediately after closing, the door can be opened without the card, thereby dramatically reducing the occurrence of troubles caused by leaving the card behind, etc., achieving the purpose of the invention. It has excellent effects.
