Description

[Detailed description of the invention] This invention consists of fitting a stopper block into the bottom of the C-shaped cross-section groove formed in the upper stile of the shoji to prevent the screen attached to the small ventilation window of the shoji from coming off easily. This invention relates to a screen door locking device.

Generally, the small ventilation window of a shoji screen is equipped with a screen door that can be opened and closed on the outside of fixed glass, movable glass, or sliding glass. However, since the rail with which the screen door engages when the screen door is opened and closed is shallow, it has the disadvantage that if there is too much space above the upper stile of the screen door, it will easily come off. Therefore, various methods of preventing the screen door from coming off have been devised, but none of them are reliable and none of them are preferable in terms of crime prevention.

The present invention was made in view of the above-mentioned circumstances, and the base of a guide piece having a guide portion is fitted into the fitting groove of the upper stile constituting the screen door, and the guide portion of the screen door is fitted into the shoji. To provide a device for preventing a screen door from coming off, in which a preventing block is fitted in a proper position in a C-shaped groove in cross section formed in an upper stile.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a front view of a sliding window showing an embodiment of the present invention, FIG. 2 is a sectional view taken along line A-A in FIG.
FIG. 3 is a sectional view taken along the line BB in FIG. 1. In the figure, 1 is a window frame, 2 and 3 are inner and outer shoji sliding doors installed in the window frame 1, and a small ventilation window 4 is provided above the inner shoji 2.

The fixed glass 5 and movable glass 6 of the small ventilation window 4 are placed on both sides of the small ventilation window 4 within a frame composed of the upper stile 7, middle stile 8 and vertical frames 9, 9 on both sides of the inner shoji 2. It is fitted through the vertical frames 10, 10 and the joining material 11.

In addition, on the outdoor side of the small ventilation window 4, there is an inner shoji screen 2.
The upper and lower sides are supported between the upper stile 7 and the middle stile 8, and a screen door 12 that can be opened and closed on the left and right sides is attached.

The screen door 12 has a cross section C as shown in FIG.
Left and right vertical frames 1 having shaped grooves 13a opening on the outer circumferential side and cross-sectional grooves 13b opening toward the outdoor side.
4, 14, an upper stile 15, and a lower stile 16, a net 17 is stretched around the frame, and the periphery of the net 17 is fixed to the cross-sectional groove of the frame via a fixture 18. .

Vertical stile 14 and upper stile 15 of the frame that constitutes the screen door
The connection portion between the vertical stile 14 and the lower stile 16 is cut at an inclined plane of 45° to each other, and the vertical stile 14 and the upper stile 1
5. From the end face opening of the lower stile 16, corner connecting blocks 19 having fitting portions in the right angle direction are fitted into fitting grooves formed in the length direction such as C-shaped grooves at the four corners. The frame is assembled.

Here, on the side where the orthogonal fitting portion of the corner connecting block 19 is fitted into the vertical stile 14, 14, a doorstop portion 19a that slightly protrudes from the doorstop surface of the vertical stile 14, 14 is integrated. It is protruding from the
When the screen door 12 is opened or closed, the door stop portion 19a comes into contact with the vertical frames 10, 10 of the small ventilation window 4.

In addition, the upper stile 15 of the screen door 12 has an upper stile 15.
A guide portion 20a protrudes from the upper surface of the upper stile 15 and is located in a range held by the corner connecting block 19 connecting the vertical stile 14, 14, and a base portion that fits into a C-shaped groove in cross section of the upper stile 15. A guide piece 20 consisting of 20b is formed approximately the entire length of the upper stile 15 of the screen door 12, and is fitted in advance before the screen door 12 is assembled.

Note that a handle 21 for opening and closing is attached to the vertical stile 14 on one side of the screen door 12.

On the other hand, as shown in FIGS. 2, 5, and 6, on the upper stile 7 of the inner shoji 2 where the screen door 12 is held, in order to prevent the screen door 12 from coming off easily,
The retaining block 22 is placed in the appropriate position on the upper stile 7.
There are places set up.

In other words, the screen door 12 installed at the middle shoji 8 of the inner shoji 2
The screen door 12 is installed between the rail 8a for the purpose of the construction and the C-shaped cross-section groove 7a that opens downward on the outdoor side of the upper stile 7.
Even if the lower stile 16 of the screen door 12 is lifted upward,
The guide piece 20 attached to the upper stile 15 of the screen door 12 is connected to the C-shaped cross-section groove 7 for the screen provided on the upper stile 7 of the inner shoji 2 so that the guide piece 20 does not come off the rail 8a of the inner sash 8.
It is regulated by a stopper block 22 fitted in a.

Here, when the screen door 12 is attached to the screen door cross section C-shaped groove 7a provided in the upper stile 7 of the inner shoji 2, the bottom surface of the C-shaped groove 7a and the screen door There is a height H between the upper end surfaces of the twelve guide pieces 20.
Due to this margin, the screen door 12 can be attached or removed.

Therefore, by fitting the stopper block 22 into the C-shaped cross-section groove 7a for the screen door of the upper stile 7, the distance _h1 between the stopper block 22 and the guide piece 20 of the screen door 12 becomes the same as that of the middle frame 8. If the locking block 22 is set so that the engagement depth h ₂ of the screen door 12 mounted on the rail 8a is smaller than h 2 and h ₁ <h ₂ , the screen door 12 is prevented from coming off.

Furthermore, as shown in FIG. 5, the locking blocks 22 can be fitted in two positions at positions equally divided into three in the length direction with respect to the upper stile 7 of the inner shoji 2. It will not come off no matter where it is placed.

Note that when installing or removing the screen door 12, the locking block 2 that has been fitted from the end surface of the upper stile 7 in advance
2 can be easily attached and detached by sliding it to one side or left and right and keeping it apart from a portion corresponding to the width of the screen door 12.

As explained in detail above, the screen door detachment prevention device according to the present invention fits the base of the guide piece from the end face into the C-shaped groove in cross section that opens on the upper surface of the upper stile of the screen door, and also inserts the guide part of the guide piece upward. It has a simple structure in which a locking block is slidably fitted into a C-shaped groove in cross section that protrudes upward from the upper surface of the stile and opens at the bottom of the shoji upper stile into which the guide part of the screen door fits. When the stop block is in a predetermined position, the screen door will not be lifted above the engagement depth of the rail, so there is no fear that it will come off. Also,
By sliding the above-mentioned retaining block, the screen door can be lifted up to the bottom of the C-shaped cross-sectional groove of the shoji upper stile in a predetermined position, making it possible to install and remove it as needed, which has practical effects. play.
