Sliding plate 3 in the form of a box-frame blind, which pushes the plate 2 out of the accommodation recess 5 in the outdoor direction or retracts it in the accommodation recess 5 of the door plate 2.
And a ventilation plate 4 made of, for example, a steel plate, which has a ventilation / ventilation property and which can be folded in a bellows shape and is formed so as to connect both end side edges of the storage recess 5 of the door plate 2 and the slide plate 3 respectively. The ventilation device according to the present invention configured as described above is provided.

As shown in FIGS. 3 to 5, the slide plate 3 is formed in a substantially rectangular shape such that the door plate 2 itself is divided at the central portion of the door plate 2, and the peripheral edge of the slide plate 3 is substantially formed. Reinforcing ribs 3A that are bent in a U shape are formed, and are firmly configured so that the slide plate 3 is not easily bent and broken from the outside even when the sliding recess 3 of the door plate 2 projects to the outside. Further, the height of the reinforcing rib 3A is substantially the same as the depth of the storage recess 5, and when the slide plate 3 is retracted into the storage recess 5, the outer surface of each of the slide plate 3 and the door plate 2 is retracted. Is almost flush with the door plate 2
By preventing the slide plate 3 from protruding, the door plate 2 is restored to the same width and thickness as the conventional door, and also has the decorative function of the door plate 2 itself.

As shown in FIGS. 3 and 5, the ventilation plate 4 supports the slide plate 3 connected to the door plate 2 so that it can be pushed out to the outside of the room and is easily destroyed from the outside. It is made of, for example, a punching board plate made of a thin steel plate in which a large number of ventilation holes 4A that are sufficiently strong and have sufficient ventilation and ventilation functions are formed, or a net-shaped band. It is formed of a plate, and its surface is coated with rustproof coating.
In order to be able to fold the ventilation plate 4 into a chevron shape and a bellows shape, the two one side edge portions of the ventilation plate 4 can be oscillated via, for example, a vertically long pin joint member 15A arranged at an appropriate interval. One end of the inner surface of the slide plate 3 is connected to the other end edge of one end of the inner surface of the storage recess 5, and one end of the other end of the slide plate 3 is swingably pivoted through the pin joint member 15B. Is pivotably attached to the side through a pin joint member 15C,

It is rotatably connected to the circular hole supporting portion 9. The tip of the advancing / retreating operation handle 13 is screwed with respect to the circular hole supporting portion 9 by, for example, a nut arranged in the circular hole supporting portion 9, so that the advancing / retreating operation is performed by removing the nut at the time of emergency leaving the room. The operation handle 13 can be separated from the slide plate 3.

When the slide plate 3 is held at the position where the door plate 2 is advanced from the storage recess 5 or the position where the door plate 2 is stored in the storage recess 5, the rib at any position of the advancing / retreating operation handle 13 is held. 13A is inserted into the notch 12A of the slide guide hole 12, and then the advancing / retreating operation handle 13 itself is rotated by, for example, about 90 degrees as shown in FIG.
It is adapted to be locked at a position other than the above to prevent the advancing / retreating operation handle 13 from advancing / retreating with respect to the door plate 2.

The advancing / retreating operation handle 13 itself is substantially at the position where the advancing / retreating operation handle 13 is pulled back to the indoor side to the maximum extent until the slide plate 3 is retracted into the accommodating recess 5 of the door plate 2. A hinge joint portion 14 is provided in the middle of the advancing / retreating operation handle 13 so as to be bent at a right angle. That is, the hinge joint part 1
Reference numeral 4 designates a storage concave portion and a convex portion provided on each of the cut surfaces of the advancing / retreating operation handle 13 which are divided and opposed to each other, and are engaged with each other so that the pin joint member is fitted into the storage concave portion and the convex portion from the side surface of the joint portion. By inserting the pin joint member, the advancing / retreating operation handle 13 can be bent in two so as to be swingable with respect to each other. By doing so, even when the advancing / retreating operation handle 13 is pulled back to the inside of the room to the maximum extent, the advancing / retreating operation handle 13 itself does not greatly extend to the inside of the room and does not become an obstacle, and the advancing / retreating operation handle 13 is carelessly pushed out. As a result, the slide plate 3 does not protrude from the storage recess 5 and safety can be ensured.

The window frame portion 6 disposed on the bottom surface of the housing recess 5 of the door plate 2 is filled with an adsorbent such as activated carbon for preventing invasion of insects and bad odors from the outside to form the window frame portion 6 shape. Insulating insect net body 7 formed in a substantially rectangular plate shape is fitted therein. For example, the insect repellent net 7 is formed in the shape of a rectangular breathable box, and the box is filled with a net, or itself is processed into a plate-like or lump-like solidified shape. The adsorbent for use is enclosed. That is, as shown in FIG. 2 to FIG. 4, the window frame portion 6 has a width of insect repellent net body at a position above the slide plate advancing / retreating mechanism 11 of the door plate 2 and below the delivery storage box B, respectively. A rectangular opening having the same length as the lateral length of 7 and a vertical width slightly shorter than the vertical length of the insect repellent net 7 is provided, and the insect repellent net 7 is provided at the upper edge and the lower edge of the opening. Concave grooves 8A and 8B for fitting the upper end and the lower end of

A guide mechanism 21 is provided for surely allowing, for example, mail, newspapers, other letters, etc. to enter the delivery storage box B regardless of the position. That is, the guide mechanism 21 rotatably pivots both ends of a shaft pin 25 provided at the upper end of one side of the introduction plate 24 into shaft holes 23 formed on both left and right sides of the lower edge of the delivery insertion port 22. On the other hand, the door plate 2 in which the delivery storage box B is arranged is provided with, for example, a substantially rectangular opening that communicates with the delivery storage box B, and groove-shaped slide guide rails 26 are arranged facing each other on the left and right edges of the opening. Then, the rollers 27 pivotally attached to both sides of the other end of the introduction plate 24 are fitted in the slide guide rails 26. It should be noted that, around the introduction plate 24, for example, a net-like protective cover 28 which is ventilated and expands and contracts so as to surround it.
Can be attached. Therefore, as the slide plate 3 moves forward and backward in the outdoor direction or retracts in the storage recess 5 of the door plate 2, the slide plate 3 moves in the vertical direction along with the forward / backward movement / storage movement. When the roller 27 rolls, the introduction plate 24 itself swings around the shaft pin 25 as a fulcrum, and the introduction plate 24 is constantly arranged between the delivery insertion port 22 and the delivery storage box B. Thus, the postal items and the like are surely stored in the delivery storage box B. Incidentally, for example, the shaft pin 2
5 is preferably screwed to the left and right sides of the lower edge of the delivery insertion port 22 with a nut or the like. By doing so, the nut can be removed at the time of an emergency leaving the introduction plate 24 (door. The plate 2) can now be separated from the slide plate 3.

Next, an example of the use and operation of the embodiment configured as described above will be described. When performing ventilation in a room, the hinge joint portion 14 of the slide plate advancing / retreating mechanism 11 of the door 1 is used. After raising the reciprocating operation handle 13 that is folded in two straightly,
While pushing the rib 13A of the advancing / retreating operation handle 13 through the notch 12A of the slide guide hole 12 of the door plate 2, the advancing / retreating operation handle 13 itself is pushed out, and the slide plate 3 is pushed out from the storage recess 5 of the door plate 2 to the outdoor direction. Push out in a shape and advance. Then, at a proper advance position of the slide plate 3, the advancing / retreating operation handle 13 itself is rotated, for example, by about 90 degrees as shown in FIG. 6, so that the rib 13A is locked at a position other than the notch 12A of the slide guide hole 12. The slide plate 3 is fixed by.

At this time, the ventilation plate 4 is opened in a mountain shape and a bellows shape between the storage recess 5 and the slide plate 3, and the outdoor air passes through the ventilation hole 4A of the ventilation plate 4 and further the insect repellent net 7 is passed. By passing through, deodorized and purified fresh air is introduced into the room. In addition, as the slide plate 3 moves in the outdoor direction, the roller 27 of the introduction plate 24 rolls upward along the slide guide rail 26, and the shaft pin 2
Since the introduction plate 24 inclines so as to face upward with 5 as a fulcrum, even if the delivery storage box B of the door plate 2 and the delivery insertion port 22 of the slide plate 3 are separated from each other, they are placed in the delivery storage box B. The mail and other items can be reliably stored.

On the other hand, if the room is not ventilated,

While folding the ventilation plate 4 and pulling back the slide plate 3 to the inside of the room as much as possible until the slide plate 3 is housed in the housing recess 5 and retracted, the hinge joint part 14 bends the advancing / retreating operation handle 13 itself at a right angle. You can leave it.

As a result, the ventilation plate 4 is accommodated in the storage recess 5,
While being folded between the slide plates 3, the slide plate 3 is housed in the housing recess 5 and is hermetically sealed. In addition, as the slide plate 3 moves in the room, the rollers 27 of the introduction plate 24 roll downward along the slide guide rails 26, and the introduction pin 24 uses the shaft pin 25 as a fulcrum.
Since the product itself inclines so as to face in the vertical direction, even if the delivery storage box B of the door plate 2 and the delivery insertion port 22 of the slide plate 3 approach each other, the mail storage box B can be reliably stored with the delivery items and the like. It is in a state where it can be done.

Further, when the door frame P, the door 1 and the like are squeezed and cannot be opened in the event of an earthquake, the insect screen 7 is removed from the indoor side and the pin joint members 15A (15B, 15C) of the ventilation plate 4 are removed. ) Is removed and the nut of the advancing / retreating operation handle 13 in the slide plate advancing / retreating mechanism 11,
The slide plate 3 is removed and disassembled by removing the nut of the shaft pin 25 of the guide mechanism 21, or the slide plate 3 itself is pierced from the indoor side together with the insect net 7 and the ventilation plate 4 is forcibly destroyed. By making the window frame 6
