Abstract: An overhead door with improved biasing means and automatic locking means includes two panels which are substantially horizontal when the door is raised and vertically aligned when the door is closed. An expandable hinge at the interface of the door panels allows the lower panel to move vertically when the door is in the lowered position with the upper end of the lower door panel is spaced from the lower end of the upper door panel. Either the lower end of the upper panel is tapered downwardly toward its outer edge, or the upper end of the lower panel is tapered upwardly toward its outer edge so that the outer edges of the panel ends contact first, biasing the interface of the panels outwardly, when the door is raised. The door also includes a latch that is engaged upon lowering the lower panel relative to the upper panel.
