DETAILED DESCRIPTION OF THE INVENTION
1 to 3 show a first embodiment of a screen device according to the present invention, in which one ridge is fixed to one side frame of a building opening, and the other ridge is operated to be pulled horizontally. Of the screen devices that open and close by doing this, the insect screen 1 is particularly illustrated. Of course, the screen device can be used not only for insect protection but also for light shielding, blindfolding, heat insulation, and the like.
[0012]
The insect screen 1 is composed of a pleated net 3 that alternately folds in the opposite direction and expands and contracts in an accordion manner, a movable rod 4A for opening / closing operation attached to one end of the net 3, and the other end. As shown in FIG. 4, the fixing rod 4B is fixed to the side frame 2B between the side frames 2A and 2B installed on the left and right sides of the opening of the building. Then, it can be opened and closed in the horizontal direction by operating the movable rod 4A.
[0013]
The building opening has side frames 2A and 2B on the left and right sides, but there is no need to provide upper and lower frames for supporting and guiding the upper and lower ends of the insect screen 1; instead, as the movable rod 4A moves. Thus, the guide bodies 5A and 5B protrude from the upper end of the movable rod 4A and the lower end of the fixed rod 4B, respectively.
[0014]
Each of the flanges 4A and 4B is formed hollow, and the movable flange 4A has an opening for allowing the guide bodies 5A and 5B to enter and exit near the upper end, and the fixed flange 4B is near the lower end. .
The guide body 5A has one end fixed to the vicinity of the upper end of the fixed rod 4B, and from the opening near the upper end of the movable rod 4A according to the expansion and contraction of the net 3 accompanying the operation of the movable rod 4A. When the net 3 is in a stretched state, the net 3 is led out along the upper end of the net 3 and guided while holding the upper end of the net 3 from both sides. When in the contracted state, it is housed inside the movable rod 4A.
[0015]
On the other hand, the guide body 5B also has one end fixed to the vicinity of the lower end of the movable rod 4A, and from the opening near the lower end of the fixed rod 4B according to the expansion and contraction of the net 3 accompanying the operation of the movable rod 4A.
