Abstract:
1. A screen device comprising: a screen that is opened and closed in a sideward direction; a roller pipe fixed in a predetermined position, wherein one of a left end and a right end of the screen is attached to the roller pipe which is configured to be rotated by an elastic force of an integrated coil spring and wind the screen on an outer periphery thereof; a screen mounting frame which is slidable in the direction of opening and closing of the screen with respect to the roller pipe, wherein the emend of the screen, which is positioned on the opposite side from the end attached to the roller pipe, is attached to the screen mounting frame, and an opening is formed along a length of the screen mounting frame, the opening being located at an opposite side relative to a side of the screen mounting frame at which the end of the screen is attached; an upper slide guide frame portion disposed in the vicinity of an upper end of the screen; and a lower slide guide frame portion disposed in the vicinity of a lower end of the screen, wherein: the upper slide guide frame portion is made up of a plurality of first rigid units, each having a pair of side wall portions arranged so as to face each other and a bridging portion connecting the side wall portions to each other, the first rigid unit being connected so as to permit relative rotation between adjacent first rigid units, the lower slide guide frame portion is made up of a plurality of second rigid units, each having a pair of side wall portions arranged so as to face each other and a bridging portion connecting the side wall portions to each other, the second rigid units being connected so as to permit relative rotation between adjacent second rigid units, the upper slide guide frame portion and the lower slide guide frame portion both have flexibility and each have a free end at one end thereof, the free end being able to be retracted into and withdrawn from an interior of the screen mounting frame so that portions withdrawn from the screen mounting frame in association with the sliding movement of the screen mounting frame maintain their linearity when being withdrawn from the screen mounting frame, each of the first rigid units has a projection at a first end of each of the sidewall portions, a through hole at a second end of each of the sidewall portions, and a shoulder formed on an edge portion of the bridging portion, the adjacent first rigid units are connected by inserting the projections of one of the adjacent first rigid units into the through holes of the other of the adjacent first rigid units, the upper side guide frame portion is configured so that the upper side guide frame portion is refracted into the interior of the screen mounting frame with a space allowance, which permits the connection between the adjacent first rigid units to be released by inserting a tool into the interior of the screen mounting frame, the upper slide guide frame portion is removable from the screen mounting frame by inserting the tool through the opening into the interior of the screen mounting frame and releasing the connection between two adjacent first rigid units, each of the second rigid units has a projection at a first end of each of the sidewall portions, a through hole at a second end of each of the sidewall portions, a smaller projection that projects outwardly from an end of each of the projections, and an elongated hole formed at an end of each of the through holes, the adjacent second rigid units are connected by inserting the projections of one of the adjacent second rigid units into the through holes of the other of the adjacent second rigid units, and the smaller projections of the one of the adjacent second rigid units into the elongated holes of the other of the adjacent second rigid units, and each of the first rigid units is of a size that is smaller than a size of each of the second rigid units, and when the upper slide guide frame portion and the lower slide guide frame portion are retracted into the interior of the screen mounting frame, the side wall portions of the first rigid units are fitted into inner sides of the side wall portions of the second rigid units, and the upper slide guide frame portion intersects the lower slide guide frame portion in the interior of the screen mounting frame.
