  • Patent number: 7891398
    Abstract: A screen device includes an expandable and contractible folding screen connected to a side frame member and to a movable stile to be opened and closed, and a translation mechanism for the movable stile. The translation mechanism includes a single wire having three or more segments arranged in rows extending through the screen. The wire segments are redirected at an inlet to the movable stile, are guided along the length of the movable stile, are redirected in upper and lower areas of the movable stile, and are guided along the lateral frame members toward the opposite frame member, thereby the wire stretches between the movable stile and the opposite frame member the same number of times as the number of wire segments extending through the screen to absorb changes in the length of the wire segments extending through the screen in accordance with movement of the movable stile.
