Abstract:
1. A screen device comprising: a screen frame including a side frame member and upper and lower lateral frame members; a movable stile guided along the upper and lower lateral frame members of the screen frame for opening and closing operations, the movable stile detachably mounted to the upper and lower lateral frame members of the screen frame; a screen having a first end and a second end in a lateral direction, the screen connected at the first end to the side frame member, the screen connected at the second end to the movable stile, and the screen contractible and expandable by folding so as to be openable and closable, respectively; a translation mechanism for translationally moving the movable stile with respect to the side frame member by constraining by one contiguous wire an attitude of the movable stile regardless of a position to which the movable stile is moved; a first mounting groove in the side frame member, the first mounting groove having an opening which faces the screen; a first fixing plate mounted to the first mounting groove so as to be detachable through the opening facing the screen, the first fixing plate: fixed to the first end of the screen, having a first front surface facing the screen and a first rear surface opposed to the first front surface, and including a plurality of first guide holes penetrating through the first front surface and the first rear surface, the first guide holes provided to insert the one wire therethrough, wherein the translation mechanism is configured such that: the one wire has segments arranged in three or more rows extending through the screen in an expansion/contraction direction of the screen, individual end portions of the wire segments extended through rows of the screen of the one wire, on a side of the movable stile, are redirected in upper and lower directions of the movable stile at inlets of the movable stile, wire segments guided in upper and lower directions in the movable stile as a result of redirection in the movable stile are all redirected in upper and lower end portions of the movable stile in the lateral direction and guided along the upper and lower lateral frame members toward an opposite frame member that faces the movable stile so that the total number of wire segments stretched between the movable stile and a side of the opposite frame member along the upper and lower lateral frame members is the same as the total number of wire segments extended through the rows of the screen, the wire segments stretched between the movable stile and the side of the opposite frame member along the upper and lower lateral frame members constitute an adjustment portion that absorbs changes in length of the wire segments extending through the screen in accordance with movement of the movable stile, the adjustment portion is configured such that at least a pair of wire segments of the wire segments stretched between the movable stile and the side of the opposite frame member along the upper and lower lateral frame members are contiguous with each other by being folded back at the side of the opposite frame member by being wound around a deflector that is provided in the opposite frame member or the lateral frame member, and individual end portions of wire segments extended through rows of the screen of the one wire, on a side of the side frame member, are all, without being penetrated through the side frame member, either (1) fixed to the first fixing plate or (2) inserted through the first guide holes of the first fixing plate from the first front surface to the first rear surface, redirected upward or downward on a side of the first rear surface by the first guide holes, wholly guided linearly along the first rear surface in the first mounting groove, subsequently inserted from the first rear surface into the first guide holes to be guided to the first front surface, and then are contiguous with wire segments of other rows extended through the screen.
