Filed:

Oct 17, 2007

Appl. No.:

11/874038

Inventors:

Ronald R. Carr - Kingsley MI, US

International Classification:

E05B 73/00

US Classification:

70 14, 70416, 70232, 292259 R, 292288, 292289

Abstract:

A security bar for quickly barricading a doorknob-operated, outward-opening door from inside a room, especially useful for fire safety doors used in schools and similar institutions. The bar spans the doorway from the knob to at least one side of the doorframe, with the ends of the bar overlying, and preferably directly engaging, the sides of the doorframe in a non-rotating fashion. The bar has a doorknob-engaging platform that engages the inner doorknob. A clamping member carried by the doorknob-engaging platform normally rests in a storage position out of the way of the doorknob while the bar is being applied to the door, but is quickly activated to clamp the doorknob to the platform. A lock is optionally engaged to lock the clamping member in place and prevent attempts to lift the bar out of engagement with the doorknob. Attempts to force the door open from the outside simply force the bar more tightly against the doorframe.

Abstract:

A door has a doorknob, and is hingedly mounted in a door frame having at least one vertical member. The door is capable of selective rotational movement between a closed configuration and an open configuration. The door has a first side and an opposed second side. The first side is oriented in a direction toward which the door opens. A barricade bar includes a flange member for selectively engaging the doorknob to prevent the separation of the flange member from the doorknob. The barricade bar also includes a frame member for coordinate engagement with the at least one vertical member. The frame member is rigidly coupled with the flange member. The barricade bar can be oriented adjacent the second side of the door so that the frame member engages the vertical member and the flange member engages the doorknob to prevent the opening of the door.
