Abstract:
1. A folding screen device comprising: a lateral frame member which is attached at an upper portion of an opening of a building, and which includes a supporting groove that opens toward a lower side and extends in an axial direction; and a plurality of screen units each including: wherein upper end portions of a plurality of first vertical frame members and a plurality of second vertical frame members in the plurality of screen units are fitted and held in one identical supporting groove in the lateral frame member so that the plurality of screen units are arranged in parallel in the opening of the building, and wherein bumping surfaces of the first vertical frame member in a first screen unit and the second vertical frame member in an adjacent screen unit are detachably connected to each other; wherein each rail of the pair of rails is provided with a slit at an intermediate position in the axial direction of each rail, the slit cutting off each rail from a tip end thereof in the width direction of each rail, penetrating through each rail toward the lower side of the lateral frame member, having an opening length in the axial direction larger than a diameter of the roller, constituting a pair, and dividing each rail of the pair of rails into a plurality of rail parts in the axial direction so that the pair of rollers provided in each of the first vertical frame members and second vertical frame members can be detached from the supporting groove through the pair of slits toward the lower side of the lateral frame member by tilting the first vertical frame member and the second vertical frame member in the axial direction of the supporting groove; and wherein the cap has a surface portion closing the slit at a level flush with upper surfaces of the rail parts adjacent to each other in the axial direction while sandwiching the slit therebetween.
