Description

[Detailed Description of the Invention] The present invention relates to a structure for installing a roll-up insect screen on the outdoor side of a window frame so that it can be raised and lowered.

In general, an insect screen for sliding doors is provided on the outside of one of the sliding doors. When this insect screen is rolled up, there is no frame to support the insect net when it is pulled down, so the insect net is agitated and becomes unstable during strong winds.

Therefore, an object of the present invention is to provide a means for stably supporting a roll-up insect screen when it is pulled down.

With the above objective in mind, this device provides a roll-up type insect screen that can be raised and lowered freely on the indoor side of the exterior sliding door, and guide bodies and locking bodies are provided on both end edges of the insect screen. These guide bodies and locking bodies engage with the window frame and the exterior sliding door, thereby stably locking the insect screen in the lowered state.

Hereinafter, the present invention will be specifically explained based on an embodiment shown in the drawings.

The roll-up type insect-proof satsushi 1 of the present invention is as follows:
As shown in FIGS. 1 to 4, it is comprised of a window frame 2, double-sliding type sliding doors 3 and 4, and a roll-up type insect screen 5.

The window frame 2 is constructed by combining a lower frame 6 such as an aluminum profile, an upper frame 7, and left and right vertical frames 8, 9 into a rectangular shape. The upper frame 7 is integrally formed with guide plates 12, 13 on its lower surface and a case 14 for storing the insect net 5 on the outdoor side. The sliding doors 3 and 4 are fitted between the rails 10 and 11 and the guide plates 12 and 13, respectively, in a horizontally movable manner.

The case 14 has a horizontal winding shaft 15 inside it.
The insect net 5 is wound around the winding shaft 15 with one end of the insect net 5 fixed.
One end of this winding shaft 15 is connected to a spiral winding spring 16.
The other end of this coiled spring 16 is fixed to a portion of the case 14. This coiled spring 16 applies a rotational force to the coiling shaft 15 in a direction that constantly pulls up the insect screen 5. A hook 18 corresponding to the hook piece 17 of the lower frame 6 is fixed to the lower end of the insect screen 5, and a U-shaped cross section is provided on the entire left edge of the insect screen 5 when viewed from the indoor side. A guide body 19 is fixed, and a locking body 20 having a U-shaped cross section is fixed in the same direction to the entire right edge. The guide body 19 is made of flexible plastic or the like so that it can be wound around the winding shaft 15, and has a guide groove 21 at a position facing the vertical frame 8. This guide groove 21 is slidably fitted into a guide piece 22 that is integrally formed on the outdoor side of the vertical frame 8. Further, the locking body 20 is similarly made of flexible plastic or the like, and has a locking groove 23. This locking groove 23 is connected to the sliding door 3 on the outdoor side.
It is removably fitted into an L-shaped locking piece 24 formed on the outdoor side of the vertical stile 3a. The mating side vertical stile 3b of the sliding door 3 on the outdoor side integrally forms a holding groove 25 for holding the locking body 20 at the outdoor side position.

Next, the functions will be explained. The insect screen 5 is rolled up by a winding shaft 15 when not in use.
When using this, the insect screen 5 is pulled down while holding the hook 18, and the hook 18 is engaged with the hook piece 17 of the lower frame 6. During this pulling down, the guide groove 21 of the guide body 19 slides downward while fitting into the guide piece 22.

Now, when the sliding door 3 on the outside side is closed,
As shown in FIG. 5, the guide piece 22 and the locking piece 2
4 sandwich a part of the guide body 19, and the holding groove 25 fits into the locking body 20, so that the insect net 5 is stopped from swinging at both ends, so that it will not sway during strong winds. He is still in a state of no delusion.
On the other hand, when the sliding door 3 moves to the right in FIG.
and the locking groove 23 of the locking body 20 is the sixth
As shown in the figure, since the insect net 5 fits into the locking pieces 24, the insect net 5 is restrained by them. Therefore, in any case, the insect net 5 is maintained in a stable state.

In the above embodiment, the coil spring 16 is used as a drive means for the winding shaft 15, but this drive means may be replaced by a motor. In addition, the hooking piece 17 and the case 14 for storing insect nets, etc.
It may be configured separately from the window frame 2 member.

According to the present invention, since the insect screen is provided in a rolled-up manner so that it can be raised and lowered, the opening of the window frame can be completely opened, and the insect screen in the lowered state can be moved up and down by the guide at its end. The insect screen is held in place by the window frame and the locking pieces of the sliding door on the outdoor side, so the insect screen is not blown around by the wind and can be held in a stable state. .
