Retractable roof with auto-liftable ceiling

Abstract

The present invention provides a sidewall system and a collapsible building using the system thereof. The sidewall system has a fixed wall, a sidewall, and a single-side eave system that has an eave panel that can be unfolded and folded along with the movement of the sidewall automatically. A collapsible building with two sidewall systems and a sliding, retractable roof is also provided. The collapsible building can create an enclosed space easily and quickly. To solve the above problems, the present invention is proposed. A multi-layered folding roof fitted with a liftable ceiling is also provided. The roof can be unfolded and retracted in the horizontal direction, and the internal multi-piece ceiling structure will unfold and fall simultaneously with the roof due to the action of the internal slide rail. The invention can be used in a variety of buildings and mobile homes.
