Description

[Detailed Description of the Invention] This invention includes a window of a building (including an entrance such as "handle 1")
This relates to the improvement of insect-proof and screen doors (hereinafter simply referred to as storerooms) installed in buildings.

The windows and windows are opened at 1M high in the summer to improve the breeze, but screens are fitted to prevent mosquitoes and flies from entering.

However, having a screen door on an open area is not only annoying, but it can also come off when moving the door to open the window.

This invention solves the above-mentioned problems of conventional storage doors, and also satisfies cases where it is desired to cover the opening of a window with a curtain or a curtain in place of a screen door.The purpose of this invention is to: The insect screen on the screen door is rolled up with a nubling roller, and the curtain is also rolled up in the same way, and when the insect screen or curtain is pulled down, mosquitoes and flies There is a screen door with no gaps for things to get in.

The details of this invention will be explained below based on the first embodiment shown in the accompanying drawings.

In the figure, 1 is an M frame for the screen door, and 2a and 2b are rollers for winding and unwinding held in parallel on the upper frame of the peripheral frame 1. A winding spring is loaded in the shaft center to provide restorability in the winding direction, and the winding machine has a well-known mechanism that can stop the winding and unwinding in the middle.

One end of the curtain 4 is wound around and fixed to the roller 2aG, the door screen 3, and the roller 2b, respectively. Reference numeral 5.6 indicates a pull-down operation bar located at the lower end of the insect screen and curtain.

On both left and right edges of the insect screen 3 and the curtain 4, as enlarged in FIG. 2, tape half-holes 8 having fastening teeth 7 of a slide fastener are sewn over the entire length thereof.

In addition, the slide fastener tape of the slide fastener tape of the slide fastener tape of the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the slide fastener tape of the slide fastener tape of the curtain 4 and the slide fastener tape of the curtain 4 is attached to Grooves 10a, 1 that engage the bulging convex i'Jl 9 on both the front and back surfaces by the engagement teeth 7 of the halves 8a, 8b.
0b (t) rail 11 is provided.

12 is a cover that covers the roller section.

The bulging convex part of the slide fastener tape half is not necessarily limited to a continuous fastening tooth 8, but a spiral filament is sewn on the tip edge of the tape half with a Q-perforation machine so that each ring r'iI+ is equally spaced. It is also possible to solidify it to form a bulging convex portion, or to integrally form a bulging convex strip on both the front and back sides +f+7 on the leading edge of the synthetic resin tape.

This invention is as described in -, and this screen door has two rollers parallel to each other on the two frames of the screen door circumferential frame and supported by bearings, an insect screen on one roller, and an insect screen on the other roller. One end of the curtain is fixed at each end, then rolled up and unwound, and a slide fastener tape is attached to the insect screen J and the left and right edges of the curtain over its entire length.
1 on the inner side of the left and right 5 frames.
A series of convex portions (or protrusions) bulging on both the front and back sides of the tape half are inserted into the tape.
Since it is equipped with two J-rails in parallel, when insect control is required by opening the glass window, the insect screen can be pulled out from the roller and extended, and the curtain can also be pulled out. It can be extended, and when the glass window is left open, the insect screen or curtain can be rolled up to improve daylight and external visibility.
This has the advantage that it can be left in place.

Furthermore, when an insect screen or curtain is pulled out and unfolded to provide insect protection, both sides of the net enter the vertical rails of the peripheral frame (7SIS rail Iη-), and the insect screen line is inserted into the rail grooves on both sides of the curtain. Since it is a bulging convex part of the slide fastener tape half, it will not come out accidentally, and therefore has the advantageous effect of completely shutting out mosquitoes and mosquitoes.

When you attach the slide fastener tape to the left and right sides of an insect screen or curtain, the bulging convex part will cause the diameter of both sides of the insect screen or curtain to become larger and the central part to be rolled up. Although it will loosen, this problem can be overcome by rubbing both ends a of the Q-roller over a small diameter as shown in FIG.
