US Patent 7272011 Computer enclosure with rotatable cover mounting assembly

A mounting assembly for computer cover includes a chassis having a rearwall, a cover mounted to the chassis, a first connecting bar and second connecting bar movably mounted on the rearwall of the chassis and a driving member mounted on the chassis. The cover has two opposite sidewalls. A protrusion extends from each of the sidewalls. Each of the two connecting bars forms a stopping portion for engaging with the protrusion.
