Description

[Detailed Description of the Invention] The present invention relates to a device for locking a screen door movably attached to the outdoor side of a sash door.

As shown in Fig. 1, in a movable screen door in which the screen door 3 is attached to the outdoor side of the inner and outer sash doors 1 and 2 that are installed in a sliding manner so that the screen door 3 can be moved left and right, the inner sash door 3 is attached as shown in Fig. 2. It is used by opening the door 1 and covering the opening with the screen door 3, but the screen door 3 cannot be locked in this state.

For this reason, when going out or sleeping, people are careless, so they have to close the inner sash door 1 and lock the inner and outer sash doors 1 and 2 with the lock 4, such as a crescent lock. The problem is that it does not provide ventilation between the indoor and outdoor areas.

Therefore, as shown in Japanese Utility Model Publication No. 51-15746, the screen door was made rotatable by 90 degrees, and the screen door could be locked by rotating the center step to a position where it interfered with the vertical stile of the outer door. something is proposed.

However, with this structure, the screen door cannot be fixed in the vertical direction, so there is a risk that the screen door will be removed in an effortless manner.

The present invention was developed in view of the above circumstances, and its purpose is to provide a screen door locking device that can securely lock the screen door by fixing it in the horizontal and vertical directions.

Embodiments of the present invention will be described below with reference to FIGS. 3 and 4.

FIG. 3 is an overall schematic plan view, and there are screen doors 12 on the inside of the window frame (not shown), inside the outside sliding doors 10 and 11 installed in a sliding manner along the outside rail.
is attached so that it can be moved left and right.

A crescent plate 13 is provided on the left side stile 10a of the inner sash door 10, and a crescent receiver 14 is provided on the right side stile 11a of the outer sash door 11.
When the outer sash doors 10, 11 are closed, a crescent plate 13 is engaged with a crescent receiver 14 to draw and lock the inner and outer sash doors 10, 11.

On the other hand, a screen door crescent receiver 15 that can engage with the crescent plate 13 is attached to the right side vertical stile 12a of the screen door 12 so as to be movable up and down. It is housed in the sill so that it does not interfere with the outer sash door 11, and when it is rotated downward and placed in a horizontal position, it protrudes further into the room than the right vertical stile 12a and is in a position where it engages with the crescent plate 13.

That is, as shown in FIG.
3 is rotatably attached, and the right side vertical stile 12a of the screen door 12 has a mounting groove 18 for the screen 17 integrally formed on the inner wall 16a of the hollow body 16, and a crescent receiver 15 for the screen door is mounted up and down with a pin 19 on the inner wall 16a. The screen door crescent receiver 15 is movably attached, and has an engaged portion 15a bent into a hook shape that engages with the crescent plate 13, and the inner wall 16a.
A stopper 20 for holding the crescent receiver 15 for the screen door in a horizontal position is protrudingly provided.

Then, the inner and outer sash doors 10 and 11 are moved to the right side to open the left side, and the left opening is covered with the screen door 12, and the screen door crescent receiver 1
5 is rotated until it contacts the stopper 20 to take a horizontal position, and the crescent plate 13 is engaged with the crescent receiver 15 for the screen door, so that the screen door 12 can be drawn toward the indoor side and fixed in the vertical and horizontal directions.

Therefore, the screen door 12 can be reliably locked to prevent it from being removed from the outside, and the right side stile 12a of the screen door and the left side stile 11b of the outer sash door can be brought into contact with each other to prevent insects from entering the room from between the two. can be prevented from happening.

The present invention is as described above.Inner and outer satsushi doors 1
Since the screen door 12 can be fixed in the vertical and horizontal directions with 0 and 11 open, the screen door 12 can be reliably locked so that it is not removed from the outside side in a knock-down manner.

Therefore, it is preferable that the user can go out or sleep while the screen door 12 allows ventilation.

Moreover, since the screen door 12 can be drawn toward the indoor side by engaging the crescent plate 13 with the screen door crescent receiver 15, insects can be prevented from entering through the gap between the screen door 12 and the outer sash 11.
