ABSTRACT:
A hinge apparatus for automated decoupling that includes an actuatable assembly normally coupled, very robust, and suitable for the hanging of a door/canopy and the like. When mounted, the apparatus is normally decoupled where rapid egress is necessary, and complete removal of the door/canopy is desired. The apparatus includes a hinge finger with a finger pin and a reciprocal hinge finger with a hinge gudgeon. The finger pin normally intersects and freely pivots with respect to the gudgeon, such as when the door/canopy is opened or closed. The actuatable assembly employs a SMDC tip device to actuate a piston that decouples the hinge. Decoupling is effected as the piston linearly shifts moving the hinge finger such that the finger pin no longer intersects the gudgeon and the door/canopy falls away.
