Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a storage box, and more specifically, a box body with an open side, a door hinged to one side edge of the open side of the box body so as to be openable and closable. The present invention relates to a storage box equipped with a locking mechanism for maintaining the door in a closed state.

[Background technology 1 Generally, this type of storage box such as a mailbox or locker is
A lock prevents a third party from opening the door, but the key can be lost1), and the lock is mechanically unlocked, so it is important to keep the key in place. Even if you do not have the door, it is relatively easy to open the door, and it is not possible to reliably prevent a third party from opening the door.

1 Purpose of the Invention 1 The present invention has been made in view of the improvement, and its main purpose is to alert a third party that the door has been opened. The purpose is to provide a storage box that prevents the door from being opened, and the other purpose is to provide a storage box that can be locked without using a key and prohibits the door from being opened without going through the prescribed procedures. The purpose is to provide storage boxes.

[Disclosure 1 of the Invention] Hereinafter, embodiments of the present invention will be described based on the drawings. 1st
As shown in the figure, the box body 1 is open to the front, and a door is provided at the upper edge of the open surface, which is movable between a position that covers the open surface and a position that opens the open surface. 2 is hinged so that it can be opened and closed. Further, when the box body 1 is used as a mailbox, a mailbox 24 is formed on the top surface of the box body 1. A return spring 3 is disposed at the hinge part of the door 2 to force the door 2 in the direction of opening the open surface of the box body 1. A knob 4 is provided protruding from the outer surface of the lower end of the door 2, and a hook 5 formed in a substantially T-shape is fixed to the back surface of the knob 4, as shown in FIG. The hook 5 constitutes a locking mechanism 10 with first and second locking bodies 6.7 disposed within the box body 1, a return spring 8, and a solenoid 9. 1st
The locking body 6 is formed in a substantially U-shape that is opened laterally, and the corner formed at the opening between the rear leg piece and the rope piece is pivoted, and the hook 5 is attached to the front leg piece. It is locked. A notch 11 is formed at the tip of the rear leg piece of the first member 11 integral 6. The second locking body 7 is in the form of a strip running in the front-rear direction, and its front end is pivotally supported, and a stepped portion 12 that engages with the notch 11 is formed in the center portion in the longitudinal direction. A return spring 8 is disposed along the left-right direction at the rear end of the second locking body 7, and the spring force of the return spring 8 causes the second locking body 7 to move its stepped portion 12 to the first locking body. It is biased in the direction of engagement with the notch 11 of No.6. A solenoid 9 is disposed at the rear end of the second locking body 7 on the opposite side of the return spring 8.
When the fill is excited, the second locking body 7 returns to the spring 8.
is moved against the spring force to release the engagement between the stepped portion N2 and the cutout portion 11.

With the above configuration, when the door 4 is closed, the hook 5 and the first locking body 6 engage with each other as shown in FIG. The two locking bodies engage each other's notches 11 and step fils 12 to prevent rotation of the first locking body 6. Therefore, the door 2 is locked and cannot be opened.

On the other hand, as shown in FIG. 4(b), when the solenoid 9 is driven to move the second locking body 7, the first locking body 6 and the second locking body 7 are moved.
The engagement state with the locking body 7 is released, and the first locking body 6 can freely rotate around the shaft. Therefore, if the door 2 is pulled at this time, the first locking body 6 will move as the hook 5 moves.
rotates, and as shown in Fig. 4(c), the 7th gear 5 and the 1st
The engagement state with the locking body 6 is released and the door 2 can be opened. When the energization to the coil of the solenoid 9 is stopped, the second locking body 7 returns to its original position by the spring force of the return spring 8, and when the door 2 is closed here, the first locking body 6 or 7 locks 5. When pushed, the door 2 returns to the engagement position with the second locking body 7, and the door 2 is locked again.

By the way, a door switch 20 is arranged inside the box body 1,
The door switch 20 is opened and closed in response to the opening and closing of the door 2. The door switch 20 is composed of a snap action switch or the like, and is disposed at a position near the opening edge of the box body 1 such that an operating knob is interlocked with the door 2. This door switch 20 is designed to activate an alarm 22 if the solenoid 9 is not activated when the door 2 is opened. That is, if the door 2 can be opened and closed manually, for example, as shown in FIG. A warning will be issued if this occurs. A reset switch 21 for resetting the alarm 22 and stopping the alarm is disposed inside the box body 11, so that the alarm 22 can be stopped after the door 2 is opened. As the alarm 22, one that generates a visual or audible alarm can be used, but usually an auditory means that generates an alarm sound is used.

The solenoid 9 is configured to be activated by a signal inputted through an input device 25 such as a numeric keypad or a card league, and a circuit as shown in FIG. 3 is used as its driving circuit, for example. That is, the determination unit 26 detects the PIN number or password inputted from the input device 25, and outputs a matching signal if it is a predetermined one, that is, a specific human power authorized to open the door 2, and the driver 127 The solenoid 9 is driven through the solenoid 9. Further, the coincidence signal is applied to one terminal of the NOR circuit 28. The door switch 20 is connected to the other terminal of the NOR circuit 28, and the other terminal of the NOR circuit 28 goes from L level to H level in response to opening and closing of the door switch 20. The output of NOR circuit 28 is applied to alarm 22. Therefore, 1-Li fixed part 26
When a matching signal is not output from the gate and the door 2 is opened, both input terminals of the N-shaped circuit become L level and the alarm 22 outputs a warning. Thereby, if the door 2 is opened without input from the input device 25, an alarm is issued and the opening of the door 2 is notified. The alarm 22 can be stopped by operating the reset switch 21, and the determination unit 26 is reset by closing the door 2 and waits for the next input.

[Effects of the Invention] As described above, the present invention includes a lock mechanism that maintains the door in a closed state and can be manually unlocked, and a lock mechanism that opens and closes in response to opening and closing of the door and opens to the outside when the door is opened. It has a door switch that outputs a signal, an alarm that outputs an alarm when an open signal is applied, and a reset switch that is placed inside the box body and resets the alarm, so when the door is opened, an alarm will be issued. It is possible to check who has opened the door and to prevent the door from being opened by a third party. In addition, it is equipped with a human-powered device such as a numeric keypad or card league, and a lock (several types) that maintains the door in a closed state and releases the locked state when a predetermined electrical signal output from an input device is applied. With these devices, it is possible to lock the door without using a key, so there is no chance of an accident such as losing the key, and the door cannot be opened unless the input device is operated according to the specified procedure. This has the advantage that it is difficult for a third party to open the door compared to such mechanical locking means.
