Abstract

The emergency egress apparatus includes a protuberance mated to a first portion of the door barricade and a keeper mated to a second portion of the door barricade. A retainer is selectively disposed between one of two positions. A first position defines the placement of the retainer that establishes an interference fit between the protuberance and the keeper. A second position defines the placement of the retainer such that it is not in contact with the protuberance or the keeper. The first position secures the first portion of the door barricaded with respect to the second portion of the door barricade, and the second position decouples the first portion of the door barricade with respect to the second portion of the door barricade.

First claim

What is claimed is:

1. An emergency egress apparatus in combination with a door barricade, the combination comprising:
a first portion of the door barricade comprising a protuberance extending therefrom, the first portion further comprising a faceplate having a receiver configured to receive a knob of a door;
a second portion of the door barricade comprising a keeper therein, the keeper configured to receive the protuberance therethrough, the second portion further comprising a backplate having a backlash cam coupled thereto, the backlash cam configured to provide an interference fit between the backplate and a frame of the door; and
a retainer selectively disposed between a first position and a second position, wherein when in the first position, the retainer establishes an interference fit between the protuberance and the keeper, and the second position of the retainer is the position in which the retainer is not in contact with the protuberance or the keeper.

2. The combination of claim 1 , wherein the retainer is an inflexible rod.

3. The combination of claim 1 , wherein the second portion further comprises:
a handle extending away from the backplate and configured to enable a user to manipulate the door barricade.

4. An outward swinging door barricade comprising:
a first portion of the door barricade comprising a plurality of protuberances extending therefrom, the first portion further comprising a faceplate and a faceplate extension, the faceplate having with a receiver therein configured to receive a knob of a door and the faceplate extension being coupled to and extending substantially perpendicular to the faceplate and having the plurality of protuberances extending therefrom;
a second portion of the door barricade comprising a plurality of keepers therein, each keeper of the plurality is configured to receive the a corresponding one of the plurality of protuberances therethrough, the second portion further comprising a backplate and a backplate extension, the backplate having a cam coupled thereto and configured to provide an interference fit between the backplate and a frame of the door and the backplate extension being coupled to and extending substantially perpendicular to the backplate and having the plurality of keepers therein; and
a retainer having a first position that establishes an interference fit between the plurality of protuberances and corresponding ones of the plurality of keepers and a second position that is not in contact with any of the plurality of protuberances or any of the plurality of keepers.

5. The outward swinging door barricade of claim 4 , wherein the second portion further comprises:
a handle extending away from the backplate and configured to enable a user to manipulate the door barricade.
