  2. Description of the Related Art A screen device in which a honeycomb screen can be expanded and folded in the vertical direction has been conventionally known. FIGS. 13 to 16 show an example of this, and show a mode in which two screen devices 1A and 1B are installed adjacent to one screen installation surface. Both screen devices 1A and 1B have substantially the same configuration, and the upper frame 2 fixed to the building opening frame or the like via the bracket 5 has an upper end portion of the screen 3 for shading and heat insulation, respectively. The lower frame 4 is connected to the lower ends of both screens 3.

The screen 3 is composed of a honeycomb screen. Specifically, a foldable flexible sheet-like material is alternately folded along the outer end fold line 10 and the inner end fold line 11 with a constant width in the opposite direction. Are joined to each other along the joint 12 parallel to the crease at a position substantially two-thirds of the width from the folded crease 10 or 11. By repeating in each folding part, the cylindrical part 13 which forms the hollow part 14 is formed in multiple layers up and down by two layers on the front and back, and the hollow part 14 is arranged so as to face in the horizontal direction. .
Such a screen device is also known, for example, from US Pat.

In the screen device of the conventional example shown in the figure, the operation cord 6 is inserted through the code lock portion 7, and one end of the operation cord 6 is inserted through the screen 3 and connected to the lower frame 4. The other end is connected to the operation knob 8. When the operation knob 8 is pulled downward, the lower frame 4 is lifted upward and the screen 3 is folded. When the movement of the operation knob 8 is stopped, the lower frame 4 is stopped at that position by the action of the cord lock portion 7. When the return handle 9 is operated, the code lock is released and the lower frame 4 can be moved downward.
Further, in the illustrated screen device, two independent screen devices 1A and 1B are provided side by side, but the upper ends of the screens are connected to a common upper frame, and the lower ends thereof are shared. It may be connected to the bottom frame.

In this type of screen device, when the production limit dimension in the horizontal width direction of the screen is less than the horizontal width dimension of the building opening, the two screen devices 1A and 1B are adjacent to each other as seen in the conventional example. If the production limit dimension in the horizontal width direction of the screen is less than the production limit dimension on the members other than the screen in the screen device or the mechanism, the two upper screens are adjacent to each other. And attached to the lower frame.
In the general-purpose product, the length of the screen 3 in the horizontal width direction may be slightly adjusted, but may be set according to some commonly used horizontal widths of the building opening. When the width is larger than that, a plurality of screens 3 are arranged in parallel on the screen installation surface of the opening.
However, when a plurality of screens 3 are arranged adjacent to each other in this way, a gap is formed between the screens, and the presence of this gap cannot completely block light, and the heat insulation effect is lowered, and it is used as a blindfold. In this case, there is a problem that the field of view cannot be completely blocked by the gap.
