Abstract:
1. A screen device, comprising: a pair of slide guide frames; a slide bar configured to enable the slide guide frames to be expanded therefrom and be stored therein; a roller pipe having first and second ends and an integrated coil spring mechanism for providing a resilient force, the roller pipe being arranged between the pair of slide guide frames; pivotally supporting bodies disposed at the first and second ends of the roller pipe; first and second screens, each screen having a first end fixed to the roller pipe, so as to be withdrawn from and wound around the roller pipe, the first screen having a second end fixed to the slide bar, wherein when the slide guide frames are expanded from and stored in the slide bar in association with movement of the slide bar, the roller pipe rotates and slides via the pivotally supporting bodies along the slide guide frames in the same direction as expansion and storage of the slide guide frames and the same direction that the screens are withdrawn from and wound around the roller pipe.
