(Embodiment 1) Embodiment 1 in which the curtain guide device of the present invention is applied to an external roll-wound sunshade screen will be specifically described with reference to FIGS. .

The basic structure of this guide device is to guide the curtain 1 by a pair of left and right guide rails 2 and 2 when opening and closing an opening such as a window of a building with the curtain 1. A pin-shaped guide member 3 having a hook head 3a for retaining at a predetermined pitch is provided on both sides thereof, and the guide rails 2, 2 are respectively provided on the left and right sides as shown in FIGS. A corrugated first guide slit 2a for guiding the guide member 3 into a waveform is provided at the back, and a corrugated second guide slit 2b for guiding the left and right side edges of the curtain 1 itself into a waveform.

The curtain 1 is made of a sheet-like screen made of an opaque, flexible soft synthetic resin sheet or the like. In the present embodiment, the curtain 1 is fully closed at predetermined intervals in the vertical direction, which is the moving direction in which the curtain 1 is guided by the guide slits 2a and 2b. A horizontal slit-shaped through-hole 5 is formed on a surface that is a lower surface in each wave portion, which is a surface that is inclined in the depression angle when viewed from the outdoor side when the waveform is formed by 2b.

The guide slits 2a and 2b formed in the guide rail 2 are formed as shown in FIGS.
The guide slits 2a and 2b are configured by combining rail members 20 and 21 in which one edge is formed separately.

The curtain 1 is housed in a screen case 4 at a predetermined location, in this embodiment, above the opening, with the upper end edge wound in a roll shape (indicated by reference numeral 1 '). It is resiliently held on the winding side by a suitable urging means (not shown), and is configured to be pulled out along the guide rails 2 and 2 as necessary.

In FIG. 2, reference numeral 6 denotes a sash frame provided at the opening of the building, that is, the curtain 1 is disposed outside the building.

In such a configuration, the guide member 3 is connected to the first
When the curtain 1 itself moves in a wave shape along the guide slit 2a, the curtain 1 itself also advances in a wave shape along the second guide slit 2b, so that the curtain 1 itself usually has a flat shape that can be rolled. Nevertheless, when the opening of the building is closed, the corrugation is formed, and the support of the left and right guide rails 2 and 2 prevents the wind from fluttering, and the curtain 1 penetrates when the curtain 1 is fully closed. Through the hole 5, a ventilation effect can be exerted inside the opening, that is, inside the room (see FIG. 4).

Further, since the ventilation through-hole 5 is formed on a downwardly inclined surface in each wave portion of the curtain 1 as shown in FIG. 4, sunlight enters (solid line in FIG. 4). ) Can be avoided, and it can be prevented from being easily peeped from outside (broken line in FIG. 4).

In the above embodiment, the guide member 3 is connected to the first guide slit 2a at the back of the guide rail 3.
