Patent ID: 8595983

Claim:
A door sealing system comprising: a door frame having an integrally formed fluid channel adapted for fluid communication with a fluid pressurization system; a door with an outer perimeter and an integrally formed fluid channel; an inflatable fluid seal disposed along the outer perimeter of the door in fluid communication with the integrally formed fluid channel of the door; a door hinge having (i) a frame hinge leaf attached to the door frame and (ii) a door hinge leaf attached to the door, wherein the frame hinge leaf and the door hinge leaf are pivotally connected together to vary an angular position of the door relative to the door frame; wherein the frame hinge leaf includes an integrally formed fluid channel in fluid communication with the integrally formed fluid channel of the door frame; wherein the door hinge leaf includes an integrally formed fluid channel in fluid communication with the integrally formed fluid channel of the door; and wherein the integrally formed fluid channel of the frame hinge leaf interfaces with the integrally formed fluid channel of the door hinge leaf to form a single internal fluid network between the door frame and the inflatable fluid seal only when the angular position is equal to or less than a predetermined angle defining a closed position of the door, whereby fluid is capable of flowing from the fluid pressurization system through the single internal fluid network to the inflatable fluid seal to inflate the inflatable fluid seal to contact an inner perimeter of the door frame to eliminate a gap formed between the inner perimeter of the door frame and the outer perimeter of the door, and the single internal fluid network cannot be tampered with or cut from an outer side of the door because there are no externally exposed fluid lines.
