Abstract:
A door safety barrier for being positioned adjacent a doorway having a door mounted therein for interfering with movement of the door relative to the doorway and defining a security opening between the door and the doorway for preventing entry therethrough, comprising:(a) a housing for being embedded into a floor adjacent the door, said housing defining a chamber therein; (b) an elongate plunger positioned within the chamber for reciprocating movement between an extended, operative position above the floor for engaging a side of the door to prevent movement of the door past said plunger, and a retracted, inoperative position below the bottom of the door for permitting passage of the door over the plunger; and (c) a latch assembly cooperating with the housing and the plunger for alternately locking the plunger in said extended, operative and retracted inoperative positions, respectively, said latch assembly comprising a follower member having a first end engaged with the interior floor of the housing and a second end for slidably engaging a complementary cam groove defined in a sidewall of the plunger for selectively moving the plunger between the extended, operative and retracted, inoperative positions.
