Description

[Detailed Description of the Invention] This invention is a card-enabled device suitable for the entrance/exit door of a room in which an automatic cash deposit machine, an automatic cash withdrawal machine, etc. are installed in a financial institution such as a bank, or a slot room of a night safe. The present invention relates to a new locking device that can be unlocked and unlocked.

The current situation is that the entrance/exit doors of rooms with automatic cash deposit machines, automatic cash withdrawal machines, etc., or the slot room of night safes are left open for users and are not locked. . Therefore, non-users, that is, those who do not have a contractual relationship with the financial institution, can freely enter and exit the room, which is not desirable in terms of safety. In addition, stores that are open during hours and days when financial institutions are not handling cash transactions,
I would like to receive and pay cash on such days and times, but
Due to the safety reasons mentioned above, the automatic deposit machine
It was not possible to use automatic drawers.

For this reason, the entrance/exit doors of rooms with automatic cash deposit machines, automatic cash withdrawal machines, and the slot room of night safes are designed to be unlockable, and the key is entrusted to the policyholder in advance for unlocking. It might be possible to pass it on.
However, it is difficult to hand over the keys to all of the policyholders when there are many policyholders, and therefore it is difficult to provide unlockable entrance/exit doors as described above. It was hot.

The present invention focuses on the above-mentioned points and the current situation where cards are used in automatic teller machines, etc., and it is possible to use a card to unlock the entrance/exit door of a room where the automatic teller machine, etc. is installed. and, preferably, locking using a card so that the card used for the automatic deposit machine, etc. can be used together with the card for unlocking the entrance door of the room where the automatic deposit machine, etc. is installed. This was done for the purpose of providing equipment.

For this purpose, the locking device of the present invention engages a night latch type automatic lock with the tip of the bar of the lock at one end, and the other end is rotatably supported on a stationary part of the device and engages with the bar. A latch to which a forced rotational force is applied so that the latch is positioned, a switch that opens and closes in conjunction with the rotation of the latch, a lever that is linked to the rotation of the latch, and a lever lock member that can be engaged with and detached from the lever. and a card reading device for checking whether the card is correct or incorrect, and when the card reading device operates, a solenoid facing the lever lock member pulls the lever lock member to release the engagement between the lever lock member and the lever. The present invention is characterized in that the pulling action of the solenoid against the lever lock member is released by either opening or closing the switch.

Based on the preferred embodiments shown in the drawings below,
The details of the present invention will be explained.

1 in the figure is a card for unlocking the locking device of the present invention, which has been entrusted to the user in advance, and the card is shown in the insertion slot 2.
It is inserted from the inside to unlock the door. In the illustrated embodiment, the card 1 has a notch 3 formed from one edge toward the center of the card 1, and numeral 4 in the figure is a card stopper, which is fixed to the device so as to fit into the notch 3 when the card 1 is inserted. This notch 3 and the stopper 4 are not necessarily necessary, and the point is that the card 1 cannot be fitted unless it has a regular notch 3. Any device that can read whether it is a card or not is sufficient.

Reference numeral 6 in the figure denotes a lever lock member, which is rotatably supported by a shaft 7 on a stationary part of the apparatus, and its rotation in the clockwise direction in the figure allows the entrance/exit door 5 to open. In this embodiment, the solenoid 8 is responsible for rotating the entrance/exit door 5 in a direction that allows the door to be opened. The solenoid 8 is operated by a card reader 9 which confirms whether the inserted card 1 is a proper one and then operates the solenoid 8. Further, in this embodiment, when the solenoid 8 is not operating, the lever lock member 6 is moved to a position away from the solenoid 8 by the elastic force of the spring 10 so that it does not rotate in the direction that allows the door 5 to open. That is, it is located at the original position and prevents the entrance/exit door 5 from opening.

In the figure, reference numeral 11 denotes a lever that engages and disengages from the lever lock member 6, and is designed to rotate in conjunction with the rotation of a latch, which will be described later. When this lever 11 is in the position where it is engaged with the lever lock member 6,
The rotation of the lever 11 is in a state where it is blocked, and therefore the rotation of the latch connected to the lever 11 is also blocked, making it impossible to open the entrance/exit door 5.

In the figure, reference numeral 12 denotes a latch, which has a roughly L-shaped cross section and has one end rotatably supported on a stationary part of the device.
It can be rotated in conjunction with the The other end is engaged with the tip of the bar 13 of the entrance/exit door 5, and this engagement is released by the above rotation. This rotation of the latch 12 is performed by the tip of the bolt 13 pushing the end of the latch 12 during the opening operation of the entrance/exit door 5, but at this time, the engagement between the lever lock member 6 and the lever 11 is released. If it is not in the closed state, the latch 12 cannot be rotated and therefore the entrance/exit door 5 cannot be opened. In the figure, reference numeral 14 denotes a micro switch that is opened and closed by the rotation of the latch 12, and the tip of its terminal 15 is brought into contact with the side surface of the latch 12. is pushed in so that the micro switch 14 is closed. The solenoid 8 is configured to stop operating when the microswitch 14 is closed. When the engagement between the latch 12 and the bolt 13 is released during the opening operation of the entrance/exit door 5, the latch 12 returns to its original position, that is, to the position where it can engage with the tip of the bolt 13. A spring elastic force is applied to the spring by a well-known wound spring (not shown). In this embodiment, a spring elastic force is also applied to the terminal 15 of the micro switch 14, and the latch 12 is brought into contact with the tip of this terminal 15, so that the terminal 15 pushes back the latch 12 and It is responsible for returning to position. The spring elastic force may be only a coiled spring wound around the shaft of the latch 12, or may be only a spring elastic force applied to the terminal 15. And this latch 12
When the terminal 15 returns to its original position, that is, the latch 12 of the terminal 15 is pushed back, the micro switch 14 is opened.

In addition, in this embodiment, the lever 11 and the latch 12 are
A pin 16 protruding from the upper end surface of the latch 12 is connected to the latch 12.
is going through. That is, when the latch 12 rotates due to the opening of the entrance/exit door 5, the pin 16 rotates while contacting the side surface of the lever 11, that is, while rotating the lever 11. Conversely, when the latch 12 is pushed back to the terminal 15 of the micro switch 14 and rotates, the pin 16 contacts the side of the lever 11 and rotates, so the lever 11 also rotates together with the latch 12. . This latch 12 and lever 11
Of course, the connection with the latch 12 and the lever 11 may be formed by integrating the latch 12 and the lever 11 instead of this type of connection.

In the figure, 17 is the drive plate, and the rotary solenoid 18
A long hole 20 into which the pin 19 of the lever lock member 6 is loosely inserted, and a through hole 22 into which the engagement pin 21 of the lever lock member 6 is loosely inserted are formed. The engaging pin 21 is inserted into the through hole 22, and the engaging pin 21 is attached to the inner edge of the through hole 22.
1, and as the rotary solenoid 18 rotates, the lever lock member 6 provided with the engagement pin 21 rotates about the shaft 7 and engages and disengages from the lever 11. In addition, the size of the through hole 22 is larger than that of the lever lock member 6.
The lever lock member 6 is large enough to allow rotation of the lever lock member 6 to release the engagement between the lever lock member 6 and the lever 11 due to the operation of the solenoid 8 from the state in which the lever lock member 6 and the lever 11 are engaged.

In the figure, reference numeral 23 denotes a holding arm, which is rotatably supported by a shaft 24 on a stationary part of the device, and is used to position the inserted card 1 and secure its position. This rotation of the holding arm 23 is carried out by contacting the side end surface of the inserted card 1, and for this purpose, a portion is bent and formed so that the side end surface of the card 1 comes into contact with the bent portion. A restoring force is applied by the spring 25 so that the holding arm 23 rotates in a direction in which it is always in contact with the card 1.

In the figure, reference numeral 26 denotes a gripping portion of the entrance/exit door 5, and when the user grips the gripping portion 26 and pulls it toward the user, the entrance/exit door 5 opens. The entrance/exit door 5 is a night latch type door so that it can be opened freely from the inside of the room in which the automatic teller machine or the like is installed, even after the latch 12 has returned to its original position. The bolt 13 is an automatic lock that can be locked automatically.

The operation of the locking device of the present invention having the above configuration will be explained.

At a predetermined time, the main switch of the device is turned on to energize the device, which causes the rotary solenoid to rotate counterclockwise in FIG. Press down to the position shown. Due to this movement of the drive plate 17, the lever lock member 6 having the engagement pin 21 loosely inserted into the through hole 22 formed therein is moved from the position shown by the dashed line in FIG. 2 to the position shown by the solid line due to the elastic force of the spring 10. The lever 11 is rotated to a position where it engages with the lever 11. When the lever lock member 6 is in this position, the lever 1
1 cannot be rotated, and the lever 11
The latch 12 connected to it also cannot be rotated,
Therefore, the entrance/exit door 5 cannot be opened. In this state, the device waits until the user performs an unlocking operation using the card 1.

Then, the card 1 is inserted through the insertion slot 2, and if the card is correct, the card reading device 9 is activated and the solenoid 8 is activated. As a result of this operation of the solenoid 8, the lever lock member 6 is attracted to the solenoid 8, rotates to the position shown by the dashed line in FIG. It will be allowed. Allowing the lever 11 to rotate is the latch 1.
2 is allowed to rotate, so that the entrance/exit door 5 can be opened. When the user grasps the grip part 26 and pulls it toward him, the latch 12 rotates due to the door opening operation, and the engagement between the latch 12 and the tip of the bolt 13 is released, so that the entrance/exit door 5 can be opened. I can do it. During this door opening operation, the terminal 15 of the micro switch 14 whose tip is in contact with the side surface of the latch 12 is pushed in by the rotation of the latch 12, and the micro switch 14 is closed. As a result, the solenoid 8 stops its operation and releases the restraint of the lever lock member 6, so that the lever lock member 6 is rotated back to its original position by the restoring force of the spring 10. However, since the lever 11 is in the middle of its rotational movement and is located below the lever lock member 6, the lever lock member 6 rotates back until it comes into contact with the lever 11. Then, the entrance/exit door 5 is opened and the latch 1 is opened.
2 and the lock 13 are released, the spring elastic force applied to the terminal 15 of the micro switch 14 acts to return the latch 12 to its original position,
As the latch 12 returns to its original position, the lever 1
1 is also rotated back to the position where it engages with the lever lock member 6. The user pulls out the card 1 from the insertion slot 2, enters the room where the automatic teller machine, etc. is installed, and closes the entrance/exit door 5, which is automatically locked and performs the above-mentioned normal operations from outside. Otherwise, the entrance/exit door 5 cannot be opened, and the automatic deposit machine etc. can be operated safely. In addition, it is preferable that the automatic deposit machine etc. not operate unless the user securely closes the entrance/exit door 5. Furthermore, while operating the automatic deposit machine etc.,
It is preferable for safety to prevent the door from being opened even if another user performs a proper opening operation of the entrance/exit door 5.

When leaving the room, the lock on the entrance door 5 is of the night latch type, so the door can be opened from the inside.

The above operation is the operation of the device when the device is energized and the rotary solenoid 18 is activated.
If the power supply to the device is cut off for some reason, that is, in the event of a power outage, the rotary solenoid 18 will not operate, so the lever lock member 6 will be closed to the lever 11.
It remains positioned in a position where it does not engage with the door, and the entrance/exit door 5 can be opened. In this embodiment, a drive plate 17 is used and a rotary solenoid 18 is used to
The lever lock member 6 is responsible for positioning the lever lock member 6 in a state in which the door 5 cannot be opened without using the regular card 1 when the power is on and a power outage, that is, in a state in which the door can be opened at all times, and this action is performed electrically. It is also possible to manually and mechanically perform the process at a predetermined time.

As mentioned above, in the locking device of the present invention, since the opening of the entrance/exit door is performed by the operation of the card reading device that reads the validity of the card, the lock of the entrance/exit door can be unlocked using the card. When used as an unlocking device for the entrance/exit door of a room where a deposit machine, automatic cash withdrawal machine is installed, or the slot room of a night safe, the card used for the automatic cash deposit machine, etc. and the lock of the entrance/exit door will be removed. It has the effect of being able to be used in combination with a card used for unlocking, making it an advantageous entrance/exit door unlocking device.
