Outward swinging door barricade
View Patent ↗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.
1. An emergency egress apparatus in combination with a door barricade, the combination comprising:
a first portion of the door barricade comprising a faceplate and a faceplate extension that is substantially perpendicular to the faceplate, the faceplate having a receiver configured to receive a knob of a door, and the faceplate extension having a first indexing feature and a clamping screw extending therefrom; and
a second portion of the door barricade comprising a backplate and a backplate extension that is substantially perpendicular to the backplate, the backplate having a backlash cam coupled thereto and configured to provide an interference fit between the backplate and a frame of the door, and the backplate extension being adjacent and in sliding relation to the faceplate extension and having a second indexing feature and a groove configured to receive the clamping screw of the faceplate extension,
wherein the clamping screw of the faceplate extension is in sliding relation to the groove of the backplate extension such that the first and second indexing features are in sliding relation in order to position the backlash cam in close conformity with an outer edge of the frame of the door, and wherein the clamping screw is configured to be tightened within the groove and secure a position of the faceplate extension relative to the backplate extension.
2. 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.
3. The combination of claim 1 , wherein the first portion further comprises:
a gusset extending between the faceplate and the faceplate extension.
4. The combination of claim 1 , wherein the backlash cam is configured to be rotatable such that it rotates a contact surface to be in contact with the frame of the door.
