ABSTRACT:
A device for tight closure of an opening in a wall including a panel which closes the opening partially and opens to one side of the opening by pivoting about a substantially fixed axis on the other side of the opening at a substantial distance therefrom. The panel is at least approximately aligned in the direction transverse to the wall with an edge of the opening. The panel closes the opening except for a gap parallel to the axis between the edge of the opening and an inside edge of the panel which is substantially parallel to the axis. A mobile flap closes the gap. It is pivoted to the panel about a second axis extending along the inside edge of the panel. At least one link is pivoted about a substantially fixed third axis on the same side of the opening as the first axis and about a fourth axis joined to the mobile flap.
