Description

[Detailed explanation of the idea] This invention relates to a screen door mounting structure.

In the conventional screen door installation structure, opposing protruding flanges are provided on the inner peripheral surfaces of the upper and lower frames of the rectangular frame, extending in the longitudinal direction of the upper and lower frames. A mounting groove with an open surface is provided, and U-wall connecting blocks for pre-fixing are fitted into the groove at appropriate intervals, and the protruding flange is inserted into the connecting block, and the upper and lower frames are connected. A mounting structure was adopted in which the upper and lower frames of the screen door were secured with screws, and the screen door was attached to the frame.

However, in such a conventional mounting structure, because the U-wall connecting blocks are provided at appropriate intervals, a gap is created between the upper sill and the upper stile of the screen door, and small insects and the like can enter through this gap. There was a risk of it entering the room.

Furthermore, in the conventional screen door mounting structure, in order to prevent the screen door from coming off, it was necessary to install a removal prevention member between the upper and lower frames and the upper and lower frames of the screen door.

This invention was devised to eliminate such drawbacks, and provides a screen door mounting structure that does not create a gap between the inner periphery of the frame and the outer periphery of the screen door.
The object of the present invention is to provide a screen door mounting structure that does not require the installation of a pre-stopping prevention member to prevent the screen door from being pre-stopped.

An embodiment of this invention will be described below based on the drawings.

FIG. 1 is a longitudinal cross-sectional view showing the screen door mounting structure according to this invention, and FIG. 2 is a cross-sectional view thereof.

In the drawings, reference numeral 1 indicates the top.

Further, reference numeral 2 indicates a lower frame.

On the inner peripheral surfaces of the upper frame 1 and the lower frame 2, opposing protrusions 3, 3 are provided extending in the longitudinal direction of the upper and lower frames 1, 2, respectively.

In addition, in the drawing, the code A indicates the shutter, and the code 4 indicates the shutter A.
The upper stile, numeral 5, indicates the lower stile of the screen door A.

Attachment grooves 6, 6 are provided on the surfaces of the upper stile 4 and lower stile 5 facing the protrusions 3, 3, respectively.

The mounting grooves 6, 6 are formed by an outdoor flange 6a, an indoor flange 6b, and a bottom wall 6C spanning both flanges 6a and 6b.

Thus, the protrusions 3, 3 are inserted into the mounting grooves 6, 6.

By the way, in FIG. 2, numerals 7 and 7 indicate both vertical frames.

On the inner circumferential surfaces of both the vertical frames 7, 7, opposing overhangs 8, 8 are provided, respectively, so as to be arranged opposite to each other in the longitudinal direction of the vertical frames 7.

The projecting portions 8, 8 are provided at a position shifted from the arrangement position of the projecting portions 3, 3 and recessed inside the room.

Further, in FIG. 2, reference numerals 9 and 9 indicate both vertical frames of the shutter A.

Mounting grooves 6, 6 are provided on the surfaces of the vertical frames 9, 9 facing the vertical frames 7, 7.

These mounting grooves 6, 6 are similar to the mounting grooves 6, 6 of the upper and lower frames 4, 5 of the screen door A described above, and are connected to the outdoor side flange 6a, the indoor side flange 6b, and the bottom wall 6C spanning both flanges 6a, 6b. is formed by.

As shown in FIG. 2, the side surfaces of the projecting portions 8, 8 and the indoor flanges 6b of the vertical frames 9, 9 are in contact with each other.

In the above, the mounting structure of the screen door A into the frame will be explained.

First, as shown in FIG. 1, the protrusions 3.
The screen door A is fitted so that the screen door A is fitted in the mounting grooves 6 provided on the upper and lower frames 4 and 5 of the screen door A.

Then, the indoor flanges 6b provided on the upper and lower frames 4 and 5 of the screen door A come into contact with the side surfaces of the protrusions 3 and 3.

In addition, the indoor side flanges 6b provided on both vertical frames 9, 9 of screen door A are the overhang portions 8, provided on both vertical frames 7, 7 described above.
Attach to the side of 8.

Therefore, the indoor flange 6b of the screen door A comes to be held between the projecting parts 8, 8 and the protrusions 3, 3, and as a result, the screen door A is installed within the frame.

Note that the distance W between the protrusions 3, 3 provided on the upper and lower frames 1, 2 and the protrusions 8, 8 provided on both vertical frames 7, 7 at a distance from the arrangement position of the protrusions 3, 3 is It is preferable to make it narrower than the thickness of the indoor flange 6b.

In one embodiment of the invention shown in the drawings, the distance W is narrower than the thickness of the knobbed indoor flange 6b.

Therefore, the indoor flange 6b of the screen door A is connected to the protrusion 3,
3 and the overhanging parts 8, 8, and can prevent the shutter A from tilting.

Thus, this invention has the above-mentioned structure, in which the protruding parts of the upper and lower frames and the indoor flanges of the upper and lower frames of the storm door are in contact with each other, and the projecting parts of both vertical frames and the indoor flanges of both vertical frames of the storm door are in contact with each other. Since the shutter is mounted with the indoor flange sandwiched between the protruding part and the overhanging part, there is no gap between the inner periphery of the frame and the outer periphery of the shutter as in the conventional case. There is no.

Therefore, there is no risk that small insects from outside will enter the room.

Furthermore, since the screen door is attached to the frame with its indoor flange firmly sandwiched between the protrusion and the overhang, it is necessary to further install a pre-prevention prevention member to prevent the screen door from being pre-prevented. Since there is no need for a screen door and there is no need for any anti-displacement members, the screen door can be firmly attached.
