The security system provided in each room can be automatically set to the alarm and release states when the key is handed over. In recent years, however, by combining with a control box section equipped with a card reader, Inside, only a limited number of people can enter and leave. For example, FIGS. 7 and 8
As shown in FIG.
In the box of is equipped with a key device to insert and store the key of the door of each room, by performing the storage operation of inserting and turning the key into the key device when leaving the room,
In addition to turning on and off a display for notifying that the user of the room has returned, it is configured to be able to turn on control outputs for lighting and crime prevention in conjunction with a relay control panel.

In order to prevent the key from being pulled out by inserting a hand through a mail inlet formed at the upper part of the door at the front of each mailbox, a shield is provided from the upper side of the protective cover surface of the key device to the side. The plate is projected in the front direction, and the key is protected by the shielding plate and the inner surface of the front door.

[0004]

However, in the security mailbox having the above-mentioned conventional structure, even if the key 7 is inserted into the key device 25, if the key 7 is not rotated, the above-described control functions are not performed. If the shielding enclosure 9 protrudes forward from the upper front side to the side surface of the protective cover 5, the insertion and removal of the key 7 and the rotation operation are obstructed, which is inconvenient. Furthermore, when the door 3 on the front of the box is opened and closed for a long period of time, the hinge of the door 3 is loosened and the front end of the door 3 is displaced downward by its own weight.

[0005] The present invention has been proposed in view of such circumstances, and when a key inserted into a keyhole is in an entry position, a shielding enclosure is provided to shield substantially the entire locking and unlocking mechanism. On the inner surface side of the door, a protrusion having a tapered portion inclined upward toward the inward direction of the mailbox body is provided, and a support seat corresponding to this protrusion is provided on the bottom surface in the box body. Another object of the present invention is to provide a security mailbox that is effective in crime prevention and disaster prevention and that is easy to use.

[0006]

According to the present invention, which is proposed to solve the above problems, a keyhole for inserting an entry / exit key interlocking with an interlocking system in a room is provided in a mailbox body. In a security mailbox in which a door that forms a mail port for mailing the main body is openably and closably attached, an inner side of the door has a lock / unlock mechanism provided with the keyhole when the door is closed. Is provided with a shielding wall that is shielded from the mailing port, and further provided on the inner surface side of the door with a protruding piece having a tapered portion inclined upward toward the inward direction of the mailbox body. The support seat corresponding to the above is provided on the bottom surface in the box body.

[0007]

When the key inserted into the keyhole is at the exit position, the projection provided on the inner surface side of the door does not contact the key, so that the door can be closed securely. If the key is left inserted, there is a possibility that a hand may be inserted through the mail entry slot above the door and extracted. For this reason, on the inner surface side of the door, when the door is closed, the entirety of the locking / unlocking mechanism having the keyhole is provided with a shielding enclosure that is shielded from the posting port, so that the key can be securely stored. I have.

Further, a projecting piece having a tapered portion inclined upward toward the inside of the mailbox body is provided on the inner surface side of the door, and a support seat corresponding to the projecting piece is provided on the bottom surface in the box body. For this reason, even if the door is displaced downward, as the door is closed, the tapered portion of the protruding piece rides on the support seat while contacting the support seat, and finally the entire protruding piece runs on the support seat And the door closes at the proper position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The construction of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a front perspective view showing a mailbox body which is a part of a security mailbox according to the present invention, FIG. 2 is an overall front view thereof, FIG. 3 is a side view of the inside of the mailbox body, and FIG. As shown in FIGS. 1 to 4 which are front views of the locked / unlocked mechanism, the security mailbox is integrally formed with a mail input unit mounted on a wall inside a front entrance of a building or the like. 1 is configured to store an entry / exit key 7 for each room, and to cooperate with each system such as crime prevention in accordance with this storage operation. A structure in which the door is inserted into a card insertion slot of a control box (not shown) mounted on the side, and when registration of an ID code stored in the card is confirmed, the locking / unlocking mechanism 25 is unlocked and the door 3 is opened. Going on.

[0010] To this end, a door 3 having a mail port 2 for posting mail to the main body 1 is attached to the front surface inside the mailbox body 1 so as to be openable and closable. At the front of the box body 1 is mounted a protective cover 5 provided with a key hole 4 on the front surface for inserting an entry / exit key 7 for interlocking with an indoor interlocking system such as crime prevention. Inside 5 is provided a locking / unlocking mechanism 25 integrated with the keyhole 4. The front end 6 of the operating member of the locking and unlocking mechanism is exposed in an opening 5a formed at the front end of the protective cover 5. An engaging member 8 locked to the front end 6 of the operating member protrudes from the inner surface of the door 3. When the door 3 is closed, the engaging member 8 is locked to the front end 6 of the operating member. It is configured to be locked automatically.

Even if the door 3 is closed, since there is a certain distance between the inner surface of the door 3 and the keyhole 4, the entry / exit key 7 is inserted and stored, and the door 3 is closed. Also the door 3
When you reach down from the mailing port 2 at the top of
The entry / exit key 7 can be taken out. For this reason, on the inner surface 3a side of the door 3, when the door 3 is closed,
A shielding enclosure 9 is provided to shield substantially the entirety of the locking and unlocking mechanism 25 having the keyhole 4. Even if the entry / exit key 7 is inserted into the keyhole 4 and stored, unless the entry / exit key 7 is operated, the interlocking system such as a crime prevention system is not linked,

For this reason, the characters "entrance" and "exit" are written at a certain interval above the keyhole 4, and when the entry / exit key 7 is inserted, the entry / exit is performed. The key 3 is directed to this "entrance" position, and in this position, the above-mentioned interlocking system such as crime prevention cannot be interlocked. However, when the entry / exit key 7 is operated to the “exit” position, a switch (not shown) provided on the back of the keyhole 4 is connected, and an indoor interlocking system such as crime prevention operates automatically. There is a configuration. 7 'is a key for opening and closing the door of each tenant room, and 13 is a wall for preventing the key 7' from popping out. However, in some cases, the user may forget to operate the entry / exit key 7 to the "exit" position and return home.

When the door 3 is closed by setting the entry / exit key 7 to the “exit” position, the door 3 can be securely closed without the projecting piece 10 coming into contact with the head of the entry / exit key 7. As shown in FIG. 6, the entry / exit key 7 is set to the "entrance" position,
, The protruding piece 10 comes into contact with the head of the exit key 7 so that the door 3 is not closed. In a security mailbox having such a configuration, the hinges and the like of the front door 3 become loose with use over a long period of time,
There is a problem in crime prevention such as that the door 3 is shifted downward by its own weight, the door 3 cannot be reliably closed, and the lock does not work sufficiently. In order to cope with such a situation, a protruding piece 11 having a tapered portion 11a that is inclined upward toward the inside of the mailbox body 1 is provided on the inner surface 3a side of the door 3, A support seat 12a corresponding to the protruding piece 11 is provided on the bottom surface 12 in the box main body 1. Even if the door 3 is displaced downward, the tapered portion 11a of the protruding piece 11 is supported as the door 3 is closed. The rider rides on the support seat 12a while being in contact with the seat 12a, and finally the entire protruding piece 11 rides on the support seat 12a so that the door 3 can be closed at an appropriate position. The support seat 12a is made of a highly durable and slippery resin material to facilitate opening and closing of the door 3.
