In general houses in Japan, for example, when leaving the window open in the middle of a hot summer night, a screen door is often installed on the outdoor side of the window to prevent insects from entering the room. In case of rainfall, Techniques such as those described in Background Techniques have been developed to protect against rain from screen doors.
It should be noted that the conventional technique for rain protection has a problem that the lighting performance has not been examined because the member is attached to the screen door.

However, in recent years, the new corona virus has created a social need for ventilation to be required during business hours regardless of the weather in stores where an unspecified number of customers enter.
In other words, in stores, windows that were previously sufficient to be closed must be kept open all the time, so additional screen doors may be installed on the windows, and at the same time, measures to protect against rain are required. .. In these applications, the lighting performance, which is not so problematic in homes, is a specific and new need to keep the inside of the store bright.

Therefore, the present invention aims to solve the urgent problem of improving the ventilation performance at low cost and easily while maintaining the daylighting property that could not be overcome by the conventional technique when the screen door is used in the store. ..

The configuration of the first invention according to the present application for achieving such an object (referring to the invention according to claim 1, the same applies hereinafter) is to provide a gap between an opening provided from indoors to outdoors and an opening outdoors. It is provided with a cover installed so as to overlap and a screen door installed with a gap leading to the opening outdoors, and the gist is that the screen door and the opening form an air flow path through the indoor and outdoor areas. ..

It can be formed that the opening is formed by a window that can be opened and closed.

A part of the screen door may be formed by the cover.

The cover can be attached to the screen door.

The cover can be installed on the outside of the screen door.

The cover may be transparent.

In the case of the configuration of the first invention, the screen door provided with a gap and the opening whose front surface is hidden by a cover form a labyrinth seal type seal structure that prevents rainwater from entering the room from the opening during rainfall. At the same time, indoor ventilation is possible because it forms an air flow path.

The window that can be opened and closed can be opened by opening a predetermined amount, and the opening can be adjusted according to the situation, and can be closed and locked as necessary.
In addition, it is possible to correspond to a commercially available standardized aluminum sash.

The screen door in which the screen door and the cover are integrated can be replaced with the existing screen door, and the number of members is reduced.

Commercially available standardized aluminum sashes can be easily remodeled without the need to remake the screen door, so construction can be done at low cost.

For example, if it is unavoidable to install an additional screen door indoors in response to the new corona, a cover will be attached to the outside of the screen door to prevent rainwater from entering the room. Is possible.

The cover part made of transparent resin or transparent glass allows outdoor light to pass through and has excellent daylighting properties.

Hereinafter, embodiments of the invention will be described with reference to the drawings.
The drawings are created by simplifying the structure of commercially available standardized so-called aluminum sash screen doors and sliding door type windows.

The rain screen is provided with an opening 11 provided from the indoor 01 to the outdoor 02, a cover 12 installed so as to provide a gap 14 in the opening 11 in the outdoor 02, and a gap 15 leading to the opening 11 in the outdoor 02. The screen door 13 and the opening 11 form a flow path for air 00 through the indoor 01 and the outdoor 02 (FIG. 1).
The screen door 13 has a structure in which the periphery of the wire mesh 13b is attached to an aluminum frame 13a to prevent insects from invading and allow air to pass through (FIG. 2).
When it rains, the cover 12 blocks rain (not shown) to prevent intrusion into the room. On the other hand, the fresh air 00 of the outdoor 02 passing through the screen door 13 changes its direction and passes through the gap 15 along the screen door 13 and also changes its direction and enters the indoor 01 along the opening 11. At the same time, the indoor air 00 conversely passes through the same flow path and goes out to the outside, so that indoor ventilation becomes possible (Fig. 1).

In the example of a commercially available aluminum sash, the screen door 13 of the shutter and the sliding door type windows 21a and 21b are supported and stored by a common upper and lower and left and right frames (not shown), and can be opened and closed freely. The cover 12 is installed so that the opening 11 formed by opening the windows 21a and 21b of the above by a predetermined amount is overlapped.
The opening 11 has a structure in which a predetermined amount of windows 21b that can be opened and closed to the left and right of the fixed window 21a are opened (FIG. 3).
Further, the window that can be opened and closed left and right or up and down may be rotatable.

The cover 12 can be installed so that a part of the screen door 13 overlaps the opening 11, and in that case, the cover 12 and the screen door 13 are integrated (FIG. 4).

The cover 12 can be attached to the screen door 13 as a separate detachable member, or can be completely fixed and attached to the screen door 13 (FIG. 5).

When the screen door 13 is installed indoors 01, the cover 12 can be installed outside the screen door 13 (FIG. 6).

If the cover 12 having the rain protection function is made of resin or glass, the cover 12 can be made transparent (FIG. 1).

The present invention relates to a rain-proof shutter that can protect against rain even if it is left open, and has industrial applicability.
