ABSTRACT:
An anti-armed robbery system is provided wherein persons enter and exit an establishment through a plurality of floor to ceiling extending walls and lockable doors made of bullet resistant materials forming a completely enclosed bullet resistant vestibule, having means for detecting the entry and exit of persons, and means responsive thereto for allowing the unhampered entry to the establishment of entering persons, and not allowing exit from the vestibule of persons exiting the establishment, unless so enabled by an employee of the establishment. Elongated, vertically oriented anti-jamming panels are provided in the doorway, which rotate about a vertical axis so that a lateral edge of the panel projects into the doorway and rotates in a direction so as to eject into the vestibule an object or person obstructing the closure of the door.
