Description

[Detailed Description of the Invention] (Technical Field) This invention relates to an improvement of a shutter device installed on the outdoor side of a glass shoji installed on a window or terrace to block wind, rain, and light.

(Background technology) A glass shoji that opens and closes the opening is provided at openings in buildings such as windows and terraces, and a shutter rail is provided on the outdoor side of the glass shoji and the shutter is pulled out onto the rail. In many cases, a shutter device is attached, which stores the shutter on the shutter rail in a door pocket. Figures 1 and 2 show an example of such a shutter device. Inside a frame 4 consisting of upper and lower horizontal frames 2, 2 and left and right vertical frames 3, 3 provided inside the opening 1 of the building, there is a frame 4 that is movable in the left-right direction along upper and lower guide rails 5, 6. Inner and outer shoji screens 7 and 8 are provided. On the outdoor side of the frame 4 provided with such shoji 7, 8, upper and lower horizontal frames 2,
An upper rail 9 and a lower rail 10 for a shutter are provided, which are integral with the shutter 2 (separate parts may be joined with screws or the like). Between these upper and lower rails 9, 10 are upper and lower horizontal stiles 11, 11 and left and right vertical stiles 12, 12.
A shutter 14 is provided with a shutter panel 13 attached to the inside of a rectangular frame consisting of a rectangular frame, and is movable in the length direction of each rail 9, 10. Furthermore, at one end of the upper and lower rails 9, 10 for the storm door, which is outside the opening 1, both rails 9, 10 are attached when the storm door is opened.
A door pocket 15 is provided for storing the upper storm door. This door pocket 15 is the gable board 1 on the rails 9 and 10 side.
6, a side plate 17 at the opposite end of the end plate 16, a bottom plate 18, and a top plate (not shown) to form a space in which one or more shutters 14, 14 are housed. This is the end plate 1 on the rails 9 and 10 side.
A gap 19 is provided between the shutter 6 and the vertical frame 3 for a shoji screen, through which the shutters 14 can be passed one by one. On the other hand, an end plate 20 is provided at the other end of the upper and lower rails 9, 10 so as to span between both rails 9, 10.
is provided. 21 is shutter 14 and shoji 7,
This is a screen door installed between 8 and 8.

In the storm door device configured in this way, when closing the storm door, the shutters 14, 14 are removed from the door pocket 15.
When pulling out the shutter between the upper and lower rails 9 and 10 to open the shutter, pull out the shutter 1 between the upper and lower rails 9 and 10.
4 and 14 into the door pocket 15.

However, the conventional shutter device constructed and operated as described above suffers from the following disadvantages. That is, when finishing the exterior wall surface of the house including the part where the door pocket 15 is to be attached, as in the case of prefabricated houses in recent years, the outdoor opening 22 of the door pocket 15 is finished.
For the purpose of reducing construction costs, there are cases in which a closing plate called a mirror plate is not provided as in the past.
In this way, if the outdoor opening 22 of the door pocket 15 is left as it is without providing a mirror plate, the wind blowing against the wall of the house will flow from this opening 22 as shown by arrows a and a in FIG. The air blows into the door pocket 15, passes through the gap 19, and enters the space 23 between the shutters 14, 14 and the shoji 7, 8. When the shoji screens 7 and 8 are closed, the air pressure inside the space 23 increases because the wind that has entered the space 23 has no place to escape. When the atmospheric pressure in the space 23 increases in this way,
The shutter 15, which has relatively low rigidity, bulges toward the outdoors as shown by the chain line in FIG. The way this bulges changes depending on the strength of the wind blowing toward the door pocket 15, but during strong winds such as a typhoon, the shutter 15
5 bulges out and comes off from between the upper and lower rails 9 and 10, and is blown away and damages the house.
Or, it may cause injury to people or animals.

(Purpose of the present invention) In order to prevent the above-mentioned dangers, the present invention has been developed to create a storm door that does not have to have a head panel on the door pocket, but does not cause the air pressure inside the shutter to rise excessively during strong winds, and that prevents the shutter from being blown away. The purpose is to provide equipment.

(Structure of the present invention) In the storm door device of the present invention, the end plate provided at the end opposite to the door pocket of the upper and lower rails that guide the storm door has a hole that communicates the inside of the storm door with the outdoor side when the storm door is closed. It forms a hole.

(Operation of the present invention) In the storm door device of the present invention configured as described above, the wind that enters the space inside the shutter from the door pocket side during strong winds passes directly through the hole provided in the end plate. Since the air pressure in the space does not rise to an extreme level due to leakage to the outside, the storm door is prevented from expanding greatly, coming off from between the upper and lower rails, and being blown away.

(Embodiments of the present invention) Next, the present invention will be explained in more detail while explaining the illustrated embodiments.

FIG. 3 shows a first embodiment of the invention. An end plate 20 provided at the end opposite to the door pocket 15 of the upper and lower rails 9, 10 (FIG. 3 shows only the lower rail 10) for guiding the shutter is provided with an end plate 20 that is attached to the inside of the shutter 14 when the shutter is closed. A through hole 24 is provided to communicate the space 23 with the outdoors. This through hole 24 is bored at a position slightly closer to the interior than the part where the vertical stile 12 of the shutter 14 contacts the end plate 20, and as shown by arrows a and a in FIG. space 2
The wind that has entered the interior of the housing 3 is smoothly discharged outside through this hole 24.

Next, FIG. 4 shows a second embodiment of the present invention. In this embodiment, the end plate 20 against which the vertical stile 12 of the shutter abuts when the shutter is closed is separate from the vertical frame 3 for the shoji screen and is hollow with a rectangular cross section. In this embodiment, the through hole 24 is bored only in the inner wall portion where the vertical frame 12 directly abuts, and the end plate 20 is passed from the space 23 through the through hole 24.
The wind blown inside the hollow part is discharged outdoors through openings at the upper and lower ends of the hollow part.

In the first embodiment shown in FIG. 3, since there is a risk that rainwater may enter the space 23 through the through hole 24, an elastic material is provided on the outer surface of the end plate 20 to cover the through hole 24. The plate may be attached by fixing only the upper end of the plate to the outer surface of the end plate to constitute a reed valve that acts so that the wind flows only from the space 23 to the outdoors through the ventilation hole 24. As shown in the figure, an elastic plate 25 may be attached to the end plate 20 to cover the through hole 24 by providing a radial cut in the central part and opening the passage only when pressure is applied to the central part. can.

(Effects of the present invention) As described above, the storm door device of the present invention has a simple configuration and can effectively prevent the pressure inside the shutter from increasing abnormally, thereby preventing the shutter from being blown away during strong winds such as typhoons. This prevents damage to houses, people, and livestock due to storm shutters blowing off.
