Foldable screen device

Abstract

The present invention provides a folding screen device. In a folding screen device which is pulled in the lateral direction, the limit of the widthwise dimension of the screen device in the opening and closing direction of the screen is eliminated. A plurality of screen units 10 in which movable vertical frame members 13, 14 are attached to both ends of a screen 12 which is expandable in an accordion manner, and the vertical frame members are adapted to be slidable along a lateral frame member 3 of an opening 2 of the building. The screen units include screen guides 20A, 20B that move out and into the interior of the vertical frame member 13 through the upper end and the lower end thereof in a bent state, are led along the upper end and the lower end of the screen in an extended state, and a parallel movement mechanism for causing the vertical frame members 13, 14 to move in parallel during the opening and closing operation of the screen.; The screen units 10 can be arranged in parallel in an opening 2 of the building by connecting the adjacent vertical frame members of the plurality of screen units 10.

Description

technical field [0001] The invention relates to a foldable screen device which can be freely opened and closed by horizontally pulling the foldable free screen, and is used for insect protection, light shading, line of sight shielding or heat insulation. Background technique [0002] In a folding screen device that can be freely opened and closed by horizontally pulling a folding screen that is freely expandable and contractible, for example, Patent Document 1 discloses the following structure, which includes screen guides that are attached to both ends of the screen. The upper end and the lower end of at least one of the frame materials are bent toward the inside and go in and out, and are led out along the end of the screen in the deployed state, thereby guiding the end of the screen. [0003] In the open state of the screen in which the screen is fully folded and stored, this screen device does not need to arrange a large part that guides the lower end of the screen under...

Problems solved by technology

[0004] Moreover, in this screen device, since in the open state of the screen in which the screen is fully folded and stored, it is necessary to configure its unfolded width within the range in which the screen guides can be completely introduced into the inside of the frame material, so the screen The width of the device in the opening and closing direction of the screen is limited, especially in openings of buildings where the width is greater than the height, and installation is difficult

[0005] Moreover, even if the width of the product can be increased by some method, since the movement distance of the operation frame becomes longer during the opening and closing operation of the screen, it is not convenient for the opening and closing operation, and it takes more effort to operate.
