Description

[Detailed description of the invention] Industrial field of application The present invention has a screen door slipping prevention device that is easy to hang and remove, which automatically functions as soon as the screen door is hung. Regarding the screen door.

BACKGROUND ART Conventional screen door slippage prevention devices require screwing or adjustment after the screen door is hung in order to function properly.

However, with this method, it was difficult to completely prevent the screen door from coming off because people forgot to tighten the screws or the adjustment was insufficient.

Problems that the invention aims to solve The conventional technology had problems because it required additional work as mentioned above, but by making the screen door fall-prevention device automatically function just by hanging the screen door. It is necessary to try to solve the above problems.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a stopper that regulates the amount of lifting of the screen door and a stopper that causes the stopper to rise and fall to prevent the screen door from coming off. It is characterized by having a slider that can be slid up and down.

Function: The screen door of the present invention is hung by pushing up the slider and raising the stopper. At this time, the slider is pushed down by the upper frame, the stopper and the slider are disengaged, and the stopper comes into contact with the outer facing surface of the upper frame. When the screen door in the lifted state is lowered and placed on the screen door rail, the stopper comes out of contact with the upper frame external facing surface and comes into contact with the screen door guide. Then, the distance between the upper frame and the top of the stopper is ensured so that the screen door does not come off.

Example Examples will be described based on the drawings.

In FIG. 1, the screen door 1 is slidably mounted in the left-right direction with the upper frame 4 sandwiched between the screen door guides 6 attached to the left and right sides of the upper stile 2 and the upper stile 2.

Attached to the back of the screen door guide 6 are a tiltable stopper 7 that is biased by an elastic tongue piece 9 and abuts against the screen door guide 6, and a slider 8 that slides up and down in sliding contact with the screen door guide 6. I'm there.

Stopper 7 makes a hole in the upper stile 2 of the screen door,
It is half-stored inside the hollow interior. A rotating shaft 12 is attached to the lower side of this stopper 7.
There is an elastic tongue piece 9 at the tip.
Due to these functions, the stopper 7 can be raised and lowered around the rotating shaft 12, and is always urged against the back surface of the screen door guide 6.

As shown in FIG. 3, the stopper 7 is in such a state that the distance a between its top 10 and the upper frame 4 is smaller than the distance b between the screen door 1 and the lower frame rail 5.

When the slider 8 is pushed up, its top 11
The top part 10 of the stopper 7 has a vertically slidable stroke so that the top part 10 of the stopper 7 can be engaged with each other by their respective projections and depressions. 2 and 4 show the engaged state when the slider 8 is pushed up.

Figure 3 shows the state after the screen door is hung.
As mentioned above, the screen door 1 does not come off during normal use because the engagement b between the screen door 1 and the lower frame rail 5 is greater than the lifting amount a of the screen door. Note that 3 in Figure 3 is the lower stile.

When removing the suspended screen door 1, push up the slider 8 and release the stopper 7, as shown in FIG.
and engage the tops. Then, the screen door 1 is lifted, the upper frame 4 pushes down the slider 8, the stopper 7 comes into contact with the outer facing surface of the upper frame 4, and the screen door 1 is removed. This state is shown in FIG.

When hanging the screen door 1, first push up the slider 8 to bring it into the state shown in FIG. When the screen door 1 is hung, the slider 8 is pushed down by the upper frame 4, and the stopper 7 comes into contact with the outer facing surface of the upper frame, as shown in FIG. Next, when the screen door 1 is lowered and placed on the lower frame rail 5, the stopper 7 comes into contact with the screen door guide 6 and does not come off as shown in FIG.

The stopper 7 in the above embodiment is an elastic tongue piece 9.
However, as shown in FIG. 6, a helical spring 13 may be attached to the rotating shaft 12', and the action of the helical spring 13 may be used to bias the rotating shaft 12'. .

Effects of the invention According to the invention, after the slider is pushed up to hang the screen door, the stopper falls down due to the biasing force of the elastic body and comes into contact with the screen door guide. As a result, the amount of lift of the screen door is regulated, and the screen door will not come off. In this way, once the screen door is hung, it will not come off automatically, and there is no need to screw or adjust the screen to prevent it from falling off after the screen door is hung.
It is easier to hang and remove, and there is no danger of the screen door coming off and falling from the upper floors of high-rise buildings.

Claims (1)

[Scope of utility model registration request] In a structure in which screen door guides are attached to the left and right sides of the screen door upper stile to hold the screen door slidably by sandwiching the sash upper frame, a stopper that elastically abuts against the screen door guide and can be raised and folded is installed inside the upper stile. The distance between the top of the stopper and the upper frame of the sash is set to be smaller than the engagement between the lower part of the screen door and the lower frame rail of the sash. A screen door characterized by comprising a vertically slidable slider having an engaging part at the top that can engage with the top of a stopper when raised.
