Detailed Description

[13] With reference to FIGS. 1-4, an embodiment of a hanger building 100 including a pair of movable hangar door/roof assemblies 110 will be described. Although the building 100 will be shown and described as a hangar including an airplane therein, in alternative embodiments, the building 100 may be, for example, but not by way of limitation, a hangar, a barn, a factory, and other large structures. Further, the vehicle/equipment inside may be, for example, but not by way of limitation, a truck, a tractor, an airplane, large farm equipment (e.g. combine), or other vehicle/equipment.

[14] The hangar 100 generally includes a support/frame structure with side walls 120 and a pitched roof 140 attached thereto. The hangar door/roof assemblies 110 are pivotally connected to the hangar 100 at overhead hinges 150 for moving the hangar door/roof assembly 110 between a closed position (FIGS. 1 , 3) and an open position (FIGS. 2, 4). Although a pair of hangar door/roof assemblies 110 are shown/described, in alternative embodiments, the hangar building may include other numbers (e.g., 1 , 3, 4, etc) of hangar door/roof assemblies 110. The hinges 150 are disposed along an edge 160 of a roof section 170, 190 of the roof 140. The hangar door/roof assemblies 110 are on opposite ends of the roof 140 and the hangar 100, facing in opposite directions. Accordingly, the length of the front roof section 170 is the same as the length of a rear roof section 190. Although the hinges 150 are shown as being located down from the crest/ridgeline 180, approximately 1/3 the distance between from the crest 180 and edge 210, in alternative embodiments, the hinges 150 are disposed at an alternative location, such as, but not limited to, 1 ) between a mid-point between the crest 180 and edge 210, and the crest 180, 2) at the crest 180, 3) near (i.e., substantially at) the crest 180, and 4) at any point between the crest 180, and edge 210.

[15] A pair of hydraulic cylinder mechanisms 220 are mounted at the top of opposite side walls 120 with mounting brackets 230 for imparting the force required to open and close the hangar door/roof assemblies 110 relative to the hangar 100. The hydraulic cylinder mechanisms 220 are connected to the hangar door/roof assembly 110 at lower mounting points 240 along a lower portion of roof section 250 of hangar door/roof assembly 110. Each hydraulic cylinder mechanism 220 includes a cylinder ram that moves in and out of a hydraulic cylinder for opening and closing the hangar door/roof assembly 110. [16] The hangar door/roof assemblies 110 include a support/frame structure and tin or other "skinning" materials for covering the support/frame structure to form roof section 250 and end section 260. The end section 260 is angled relative to the roof section 250 so that when the hangar door/roof assembly 110 is closed, as shown in FIG. 1 , the end section 260 forms an end wall 130 and the roof section 250 forms part of pitched roof 140. As shown in FIGS. 3 and 4, the end section 260 may include a doorway/door 270 that one may use to enter and exit the hangar 100 when the hangar door/roof assembly 110 is closed. In alternative embodiments, the end section 260 may include one or more doors of the same or different sizes/configurations to facilitate ingress/egress of different objects (e.g. pedestrians, vehicles, equipment) while the hangar door/roof assembly 110 is closed. The hangar door/roof assembly 110 includes a bottom edge 280 along a bottom of the hangar door/roof assembly 110.

[17] In use, the hangar door/roof assembly 110 is opened to the position shown in FIGS. 2, 4 for egress and ingress of an airplane and/or other vehicle/object. In this position, the bottom edge 280 of the hangar door/roof assembly 110 is raised to a high-enough position so that the highest point of the airplane (e.g., top of tail) clears the bottom edge 280 of the hangar door/roof assembly 110. [18] To raise the hangar door/roof assembly 110, the hydraulic cylinder mechanisms 220 are actuated to cause the cylinder rams to move outwardly from the hydraulic cylinders. The extension of the cylinder rams forces the hangar door/roof assembly 110 upwardly, with the hangar door/roof assembly 110 pivoting upwardly at the hinges 150. With the hangar door/roof assembly 110 raised, as shown in FIGS. 2, 4, the plane can easily enter and exit the hangar 100 without contacting the hangar door/roof assembly 110. [19] To lower the hangar door/roof assembly 110, the hydraulic cylinder mechanisms 220 are actuated to cause the cylinder rams to retract into the hydraulic cylinders. The retraction of the cylinder rams forces the hangar door/roof assembly 110 downwardly, with the hangar door/roof assembly 110 pivoting downwardly at the hinges 150. With the hangar door/roof assembly 110 closed, as shown in FIGS. 1 , 3, the plane and inside of the hangar 100 are protected from the environment. It should be noted that weather-tight resilient seals (e.g., compressed foam seal) may be disposed along edges of the hangar door/roof assembly 110 and the hangar 100 (where the two come together). [20] With reference to FIG. 5, which shows multiple hangars 100a side by side, another embodiment of a hangar 100a including a movable hangar door/roof assembly 110a will be described. The hangar 100a is generally similar to hangar 100 (similar/same elements will not be described and/or will be referenced with like reference numbers, but with "a" suffix), except the hangar 100a has a construction/configuration that is 14 the construction/configuration hangar 100 shown in FIGS. 1 -4, and the hangar 100a includes a hangar door/roof assembly 110a that is hinged at or near a crest/ridgeline 180a instead of hinged 1/3 the distance from crest/ridgeline 180 to edge 160 as shown in FIGS. 1 -4. In alternative embodiments, the hangar door/roof assembly 110a of the hangar 100a includes any portion of the roof 140a and includes hinge distances from the crest/ridgeline 180a other than those shown.

[21] The hangar 100, 100a is advantageous in that the hangar 100, 100a uses less space than a traditional T hangar, the hangar 100, 100a uses less steel than a traditional T hangar, and the hangar 100, 100a has a lower profile than a traditional T hangar.
