Description

[Detailed Description of the Invention] The present invention relates to a screen door suitable for attachment to a hinge-mounted opening/closing door mainly used in entrances and the like.

Opening the entrance door during the summer season to improve indoor air circulation has become an indispensable way to cool down the summer in modern small and compact homes. Since it is inconvenient for people to enter from there, I would like to install a screen door at the entrance to prevent them from entering.

Modern entrance doors do not have the space to install sliding doors that take up a lot of space, so many homes use hinge-mounted doors that can be used with the opening width of ÷ or ÷, and most of these doors are installed on the outside. will be opened to.

As a further solution to the problem under the above conditions, it is well known that a screen door having the same width as the inside of the doorway is attached so as to open from the inside.

However, in the above proposal, the lower frame of the screen door moves back and forth over a wide range in close proximity to the knocking surface of the entrance when the screen door is opened and closed, so there is a concern that footwear cannot be placed within that range.

As a solution to the above-mentioned defects, it is well known to install an accordion curtain type screen door.

However, the entrance door is in direct contact with the outside air and is strongly affected by wind and rain, so not only do they have the problem of being blown open by the wind, but they also take up space when stored, making the narrow entrance even narrower.

The purpose of the present invention is to improve the above-mentioned defects, and to create and provide a sturdy screen door for opening/closing doors that occupies the minimum area of a narrow entrance when opened, closed, and stored, and is free from the risk of being blown away by the wind. That's true.

The configuration of the present invention will be explained in detail below using its specific embodiments.

In the embodiment shown in Fig. 1, 3 and 4 are doors that open outward (double door) by the action of hinges 5 and 6, respectively, and the width ratio is such that door 3, which is normally opened and closed, is opened in an emergency. It is made twice as large as the door 4 on the user side.

However, the ratio between the two is 1:1 to 2:1, which is the same width for both.
．． The screen door according to the present invention can be installed within the range between.

Even in the case of a fixed type in which opening of the door 4 on the narrow side is omitted, the effects of the present invention can be achieved.

7 and 8 are a pair of screen doors with the same width,
Both doors are connected to each other by a hinge 9 that can be folded inward to the inside of the entrance, and when they are unfolded, the space is comparable to the width of the frontage created by opening the one door 3. Closed.

The heights of the screen doors 7 and 8 and the height of the door 3 are the same.

The end surface sb (see FIG. 2) of the side frame 8a of the proximal screen door 8 of the pair of screen doors 7 and 8 is attached directly to the sleeve 4a of the other door 4 or to the door stop 10 attached to the sleeve.
As shown in FIG. By the action of the hinge 11, the screen door 8 can be prevented from protruding to the inside of the entrance to a minimum, both when it is unfolded and when it is folded and stored.

Appropriate locking means 12 and 13 are provided to maintain the pair of screens 7 and 8 in their unfolded position.

The pair of screen doors 7 and 8 are the doors of one door 3, so when they are unfolded as shown by the solid line in Figure 1, they pass through a small space inside the entrance and open the frontage of door 3. On the other hand, since they each have the same door as the other door 4, if they are folded and stored as shown by the two-dot chain line in Figure 1, they cannot be stacked behind door 4. Moreover, when the other door 4 is opened, it follows along with the iron P4, so it does not get in the way at all.

The above effects result from the special structure in which the opening/closing proximal ends of the screen doors 7 and 8 are connected to the sleeve 4a of the other door 4, and are convenient for use in the entrance door of a house.
