Claim:
1. An apparatus comprising: (a) an opening bounded by a frame including a hinge jamb, said frame defining a plane of closure; (b) a panel; (c) a hinge interconnecting said panel and said hinge jamb and configured to hang said panel relative to said opening so that said panel is swingable about a hinge axis between an open position removed from said opening and a closed position in which said panel is aligned parallel to said plane of closure with a portion of said panel within the opening; and (d) an engagement configuration comprising: said engagement configuration being configured such that said panel swings freely about said hinge axis between said open position and said closed position, and such that, when said panel assumes said closed position, said second engagement surface is brought into overlapping relation with said first engagement surface such that force directed to displace said panel within said plane of closure away from said hinge jamb is opposed by engagement of said second engagement surface with said first engagement surface, and wherein said hinge axis is located between said second engagement feature and said portion of said panel that lies within the opening when said panel is in said closed position when viewed from a direction perpendicular to the plane of closure.
