<p>PROBLEMS TO BE SOLVED: To simplify the structure of a translation mechanism in a screen device in which any number of intermediate segments of a wire may be extended, and at the same time to simplify assembly and installation adjustment of the translation mechanism. SOLUTION: In a screen device including an expandable and contractible folding screen 1 that is connected at one end thereof to a side frame member 11 and at the other end thereof to a movable stile 15 so as to be capable of being opened and closed, and a translation mechanism provided for the movable stile 15, the translation mechanism includes a single wire 5 having three or more segments arranged in rows extending through the screen 1. The wire segments arranged in rows are redirected at an inlet to the movable stile 15 and are guided along the length of the movable stile 15. All of these wire segments are redirected in upper and lower areas of the movable stile 15 and are guided along the lateral frame members 12, 13 toward the opposite frame member 14, so the wire is stretched between the movable stile and the opposite frame member the same number of times as the number of wire segments extending through the screen 1 to absorb changes in the length of the wire segments extending through the screen in accordance with the movement of the movable stile.</p> |
