ARRANGEMENT FOR SECURING A PANEL CLOSURE

摘要

A closure includes a panel closing against a frame. A set of abutment surfaces for supporting the panel against applied forces is completed by a displaceable abutment block which selectively assumes an engaged state disposed between an abutment surface of the panel and an abutment surface of a strike jamb. The geometry of engagement is such that forces acting on the abutment block opposing opening of the panel are primarily compressive forces. Certain implementations additionally, or alternatively, employ abutment blocks for locking along the lintel or the threshold of the opening.

主权项

1. 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 arrangement associated with said panel and said hinge jamb and configured to hang said panel relative to said opening so as to be swingable between an open position removed from said opening and a closed position in which said panel is aligned parallel to said plane of closure within the opening; and (d) an engagement configuration comprising:
(i) a projection located in fixed relation to said hinge jamb, and(ii) an engagement feature rigidly associated with said panel, said engagement configuration being configured such that said panel swings freely between said open position and said closed position, and such that, when said panel assumes said closed position, said engagement feature is brought into engagement with said projection such that force directed to displace said panel within said plane of closure away from said hinge jamb is opposed by engagement of said engagement feature with said projection.
