Description

[Detailed Description of the Invention] -Field of Industrial Application-The present invention relates to a receiving box for postal items, etc., installed inside a fire door of a high-rise house or the like.

-Prior Art-As is well known, heat-resistant iron fireproof doors, which are "Otome fire doors" according to the Building Standards Act, are used as the doors of each door used in high-rise houses such as condominiums. In other words, this "Otsukin fire door" is a single steel fireproof door that has no openings other than the opening for receiving mails, newspapers, etc. in order to prevent burning in the event of a fire. It is required to have a structure in which the opening is covered with an iron plate or the like which is always closed.

For this reason, the present situation is that a fireproof receiving box having an iron flap that covers the above-mentioned opening is installed inside the conventional fire door.

-Problems to be solved by the invention- By the way, since the outside of the fire door as described above is always illuminated by a corridor light, etc.
The entrance light inside the room is normally turned off, which means that it cannot be illuminated from outside through the fire door.

Therefore, the footsteps of the entrances of the current high-rise houses are in a dark state day and night, and not only do they feel anxiety due to the darkness, but they are extremely dangerous for old people and infants who do not feel their feet.

SUMMARY OF THE INVENTION An object of the present invention is to obtain a structure that is energy-saving and can easily illuminate the indoor foot of a fire door in view of the problem of darkness at the entrance of a conventional high-rise house as described above.

-Means for Solving the Problems-To achieve this object, the present invention is directed to a receiving box such as a postal item installed inside a fire door of a high-rise house or the like.
A heat-resistant transparent plate that covers the opening of the fire door from the inside and that can be opened and closed, and is arranged inside the receiving box in a state of facing the transparent plate and reflects external light incident from the transparent plate in a substantially downward direction. The present invention proposes a receiving box such as a daylight-type postal item that includes a reflecting plate and a through hole formed in a lower portion of the receiving box to transmit light reflected by the reflecting plate to an indoor space. In the receiving box for this daylight-type mail, etc., the fluorescent paint inside the receiving box that receives a part of the reflected light from the reflection plate, and for taking out that is opposed to the fluorescent paint and at least a part of which is made of a transparent plate An opening / closing door may be provided.

-Embodiment- Hereinafter, with reference to the drawings, details of a receiving box for a daylight-type mail item according to the present invention will be described.

As shown in FIG. 5, an opening H is formed in the door D, which is a fireproof door, and the receiving box 1 according to the present invention is fixed to the inside of the door D corresponding to the opening H.

The receiving box 1 which can be fixed to the door D by the pair of mounting portions 11,
For example, it is molded from a metal plate such as stainless steel, and a lighting part 5 having substantially the same area as the opening H is formed on the front wall thereof, and the lighting part 5 is supported by the receiving box 1 so that it can be opened and closed by a shaft 10. Since it is covered with the transparent plate 6 such as meshed glass which is urged in the closing direction by the spring, it is possible to comply with the regulation standard of "Class B fire door" in the Building Standard Law.

Further, since the reflecting plate 2 having a cylindrical curved surface is installed inside the receiving box 1 at a position facing the transparent plate 6 in a substantially horizontal direction, the outdoor light incident through the transparent plate 6 is reflected by the same. It is reflected substantially downward by the plate 2. Fine glass particles that diffusely reflect incident light or fluorescent paint that fluoresces due to incident light energy can be added to the reflector 2.

In addition, a plurality of through holes 9 having a large area for transmitting the reflected light from the reflection plate 2 toward the room are formed in the lower part of the receiving box 1. On the inner surface of the front wall of the receiving box 1 of the illustrated embodiment, a flat reflector plate 3 for receiving a part of the reflected light from the reflector plate 2 is provided. Fluorescent paint 4 that emits fluorescence on the surface of the reflector 3
Is applied. The lower outlet 15 of the rear wall of the receiving box 1 facing the fluorescent paint 4 in a substantially horizontal direction is closed by a transparent opening / closing door 8 framed by an edge 7. The opening / closing door 8 without the attachment hinge can be opened and closed by gripping the handle 14 planted in the handle 13, but the opening / closing door 8 is locked in the closed position by the plug 12. In the figure, reference characters L and L'indicate outdoor light incident paths.

Since the inbox for mails and the like according to the illustrated embodiment has the above-described structure, outdoor light such as sunlight and corridor lights is transmitted through the transparent plate 6.
The light incident on the inside of the receiving box 1 through the light is reflected by the reflection plate 2. Therefore, the indoor foot of the door D, which is always in the dark, is illuminated by the reflected light from the reflection plate 2 that passes through the through hole 9, and the foot inside the entrance is always bright even when the entrance light is not lit. Can be kept. For this reason, since the footsteps of the entrance seen from the room become brighter, it is possible not only to improve the living comfort, but also to avoid the risk of anxiety for the elderly and infants due to the footstep lighting.

Further, in the illustrated embodiment, since the fluorescent paint 4 is applied to the inside of the receiving box 1, the emission color of the fluorescent paint 4 seen through the opening / closing door 8 and the fluorescent color of the fluorescent paint 4 transmitted through the hollow 9 are shown. Can improve the ambient light condition inside the entrance. Further, the presence of the contents of the receiving box 1 can be known even from a distant position by the transparent state of the fluorescent paint 4 through the opening / closing door 8, which makes the receiving box easy to use.

-Effects of the Invention-As is clear from the above description, according to the present invention, the outdoor light transmitted from the heat-resistant transparent plate that closes the opening of the fire door is reflected by the reflection plate inside the receiving box to prevent it from passing through. Since the indoor light of the fire door is illuminated by the reflected light that has passed through the hole, it is possible to obtain a receiving box for daylighted mail items and the like, which can eliminate the darkness on the indoor side of the entrance. Further, in the present invention, by using a fluorescent paint and a transparent door for the receiving box, it is possible to obtain a highly practical receiving box that can simply improve the color of the lighting environment and know whether mail has arrived or not. .
