Hangar Door and Roof Assembly and Method of Use

Abstract

A combination hangar door and roof assembly including a door section and a roof section that pivot relative to a roof of a hangar for opening and closing the hangar to allow the ingress and egress of an airplane or other object.

1 . A door assembly for a building including a support structure, walls, and a roof, comprising:
 a combination hangar door and roof assembly pivotably coupleable to the support structure for opening and closing the building to allow the ingress and egress of an object,   wherein the combination hangar door and roof assembly is a door that forms at least part of the roof.   
     
     
         2 . The door assembly of  claim 1 , wherein the building includes a pitched roof and the combination hangar door and roof assembly includes a roof section to form at least part of, and be flush with, the roof. 
     
     
         3 . The door assembly of  claim 1 , further including one or more hinges to pivotably coupleable to the combination hangar door and roof assembly to the support structure. 
     
     
         4 . The door assembly of  claim 1 , further including one or more hydraulic cylinder mechanisms operably coupleable to the combination hangar door and roof assembly and the support structure for opening and closing the combination hangar door and roof assembly. 
     
     
         5 . The door assembly of  claim 1 , wherein the roof includes a crest and an edge, and the combination hangar door and roof assembly is pivotably coupleable to the support structure at any distance from the crest to the edge where the combination hangar door and roof assembly is a door that forms one of at least part of the roof and all the roof. 
     
     
         6 . The door assembly of  claim 1 , wherein the roof is a pitched roof, and the combination hangar door and roof assembly includes a roof section and an end section, the roof section to form part of the pitched roof and the end section to form an end wall when the combination hangar door and roof assembly is in a closed condition. 
     
     
         7 . The door assembly of  claim 1 , wherein the roof section and the end section include skinning material. 
     
     
         8 . The door assembly of  claim 1 , wherein the combination hangar door and roof assembly is one of more than one combination hangar door and roof assembly for the building. 
     
     
         9 . The door assembly of  claim 1 , wherein the building includes opposite ends and the combination hangar door and roof assembly is one of a pair of combination hangar door and roof assemblies to face in opposite directions and are pivotably coupleable to the support structure for opening and closing the building at the opposite ends to allow the ingress and egress of an object. 
     
     
         10 . The door assembly of  claim 1 , wherein the building includes an end and the combination hangar door and roof assembly is a single combination hangar door and roof assembly that is pivotably coupleable to the support structure for opening and closing the building at the end to allow the ingress and egress of an object. 
     
     
         11 . A method of using a door assembly with a building including a support structure, walls, and a roof, comprising:
 pivoting the combination hangar door and roof assembly of  claim 1  relative to the support structure of the building so that at least part of the roof raises to open the building to allow the egress of an object; and   egressing the object out of the building through an opening created by the raised combination hangar door and roof assembly.   
     
     
         12 . The method of  claim 1 , further including pivoting the combination hangar door and roof assembly relative to the support structure of the building so that at least part of the roof lowers to close the building.
