  • Patent number: 4671014
    Abstract: A very secure entry door barricade system is obtained with a specially configured elongated bar which extends generally horizontally across the width of a door. A hasp assembly, which is very firmly anchored to the building structure, includes a pivotally movable hasp adapted to selectively engage a hook portion of the bar. At the hinge edge, the elongated bar is very securely anchored by a conventional hinge pin which passes through a vertical aperture in the bar and back into its hinge assembly. An alternative configuration for double doors employs an elongated bar on each door, the bar pair being generally in horizontal alignment with respective hook portions situated in close proximity to receive a ring over both hook portions. The ring, when in place, thereby serves to closely limit the extent to which either or both doors can be opened.
