Description

[Detailed description of the invention] The present invention is a sash with a screen door frame that can be used to open and close windows such as casement windows, sliding windows, projecting windows, and outside-folding windows with the screen attached to the indoor side of the sash. Regarding structure.

Generally, glass shoji for casement windows, sliding windows, projecting windows, and outward-folding windows open so as to pop out toward the indoor side, making it impossible to attach a screen door to the outdoor side of the window.

However, when attempting to attach a screen door to the indoor side of this type of window, a problem arises in that the screen door becomes an obstruction, making it impossible to open and close the glass shoji.

In the past, in order to solve this problem, various proposals were made for opening and closing means for opening and closing the glass shoji while keeping the screen on the indoor side, but the present invention is a new method for the screen door. It is an object of the present invention to provide a screen door device that allows the above-mentioned window to be easily opened and closed even when the screen door is attached to the indoor side.

That is, in the screen door device according to the present invention, the opening of the frame body assembled by connecting the upper and lower horizontal frame members and the left and right short frame members is divided into upper and lower halves by the middle crosspiece, and one opening is covered with an insect screen. At the same time, a movable screen door that closes the other opening is incorporated into the shoji running section provided on the opposite short frame members to form the screen door frame, and this screen door frame is used as the interior of the sash frame. It is characterized in that it is removably fitted into the inner opening and fixed in close contact with the sash frame using a detachable fixture on the edge of the indoor opening.

Hereinafter, the present invention will be explained according to an illustrated embodiment.
, shows the case where a screen door frame B is attached to the indoor side of A, and this screen door frame B is made up of upper, lower, left and right frame members 1, 2, and 3 that are molded separately from the sash frame S of the casement window A. .4 to be connected and assembled.

As shown in FIG. 2, the left and right vertical frame members 3 and 4 are molded to have the same cross-sectional shape, and each has a hollow portion 6 provided with a vertical holding rope fitting groove 5. A groove-shaped shoji running part 7 is integrally provided on the indoor side of the part 6.

The upper Azusa material 1 and the middle crosspiece 8, which are connected by passing between the two vertical frame members 3 and 4, have net presser rope fitting grooves 9 and 1 on their opposing surfaces.
0, and the opening of the screen door frame B is divided into upper and lower halves by the middle crosspiece 8. By stretching the insect-proof net 11, a fitting section A is formed above the frame B by the insect-proof net 11.

Moreover, the movable screen door C incorporated between the shoji running parts 7, 7 is formed in a size that closes the lower opening of the frame opening divided into two parts, and the short roots 12 constituting the movable screen door C are ,1
A plate spring 16.17 is installed in the outer concave grooves 14, 15 of 3, and the plate spring 16.17 is attached to the groove-shaped shoji running parts 7, 7.
By coming into pressure contact with the inner wall of the movable screen door C, the movable screen door C can stop vertical movement at an appropriate position.

In this way, the screen door frame B that forms the fitting portion A and incorporates the movable shoji C is removably attached to the indoor opening of the casement window A. A vertical groove 18 is formed at the upper end of the bag frame materials 3 and 4, and an indoor side horizontal piece 20 of an upper frame 19 forming a sash frame S for a casement window.
At the same time, the indoor side locking piece 22 provided on the bottom frame material 2 of the screen door frame B is locked to the bottom frame 23 of the sash frame S, and The left marsupial frames 3 and 4 are fixed using fixtures 24 attached to the upper ends thereof.

This fixing tool 24 can project a fixing shaft 25 above the screen door frame B by rotating a rotor that projects toward the indoor side. Indoor side horizontal piece 2 of the satsushi upper frame 19 that corresponds to the edge
It abuts and locks at zero.

By fixing the screen door frame B using the fixture 24, the upper Azusa material 1
Since it is in close contact with the support piece 21 of the sash upper frame 19, the space between the sash frame S and the screen door frame B is sealed, and insects can be prevented from entering.

When opening or closing the casement window A, the movable screen door C is moved upward to open the lower opening of the screen door frame B, and the locking handle (not shown) of the casement window A is operated. After opening the glass shoji 26, the movable screen door C is lowered to close the lower opening.

Of course, by rotating the rotor of the fixture 24 in the opposite direction, the abutment and locking relationship of the shaft body 25 can be released, and the screen door frame B can be removed from the indoor opening.

As described above, the present invention is a screen door frame having a movable screen door that is removably attached to the interior side of a sash frame such as a casement window, and by moving the movable screen door at any time, a required opening can be created in the frame body. This makes it possible to easily open and close casement windows, and of course, by closing the movable screen door, the insect repellent effect is reliably exhibited.

Since the screen door frame is detachable, it has the advantage that it can be removed to clean the area around the opening of the sash frame or to replace a damaged screen if necessary.

In addition, since the screen door frame is in close contact with the sash frame, it is possible to reliably prevent insects from entering.

Note that a decorative lattice body 27 can be attached to the outdoor side of the glass shoji 26 of the bay window casement A shown in the figure.

Further, the cross-sectional shape of the screen door frame material, the cross-sectional shape of the middle crosspiece, the structure of the movable screen door, and the structure of the fixture are not limited to those shown in the drawings.
