Abstract: A shelter includes: a shelter framework including (a) first and second frames, and (b) a plurality of purlin members, each purlin member interposing between the first frame and the second frame; a cover positioned over the shelter framework; a doorcase, secured to and positioned within the first frame, having a central portion, a first side portion and a second side portion, the central portion having an upper section that includes tracks on each side; a center door, extending from a top of the central portion of the doorcase to a bottom of the central portion of the doorcase, having a sliding structure on each side edge; and a first and a second door, each extending from the top of the corresponding side portion of the doorcase to the bottom of the corresponding side portion of the doorcase, the side doors being positioned on opposing sides of the center door, each side door including a track on the side adjacent the center door.

Abstract: A shade cover or “solar fly” is provided for reducing the thermal radiation effects of the sun on an associated shelter. By blocking the sun's rays to a significant degree, the outer surface temperature of an associated shelter is reduced, which results in less heat transfer into the interior space thereof. The shade cover and associated shelter may be cooperatively configured to employ natural convection to aid in reducing heat transfer into the interior space of the associated shelter. Natural convection known as the chimney effect may be used to reduce heat transfer into the interior space of the associated shelter. Such reduction of heat transfer into the interior space reduces the air conditioning load needed to maintain the interior space of the associated shelter at ambient temperatures of, for example, 76-84 degrees Fahrenheit among others.

Abstract: In a portable shelter frame, a frame support is selectively articulable between an erected state and a collapsed state. The frame support includes a central frame member; a pair of upper arcuate frame members rotatably coupled to the ends of the central frame member, each pair of frame upper frame members being selectively moveable between a first, fixed position when the frame support is in the erected state and a second, fixed position when the frame support is in the collapsed state; and a pair of lower arcuate frame members rotatably coupled to the other ends of the upper arcuate frame members, each pair of frame lower frame members being selectively moveable between a first, fixed position when the frame support is in the erected state and a second, fixed position when the frame support is in the collapsed state.

Abstract: A shade shelter includes a frame, roller assemblies, and one or more solar panels selectively mounted on the roller assemblies so as to be movable with respect to the frame. The shade shelter may be erected over an associated structure in order to at least reduce the thermal radiation effects of the sun on the associated shelter.

Abstract: A frame is articulable between erected and a collapsed states and includes first and second frame supports. Each frame support has a pair of center frame members rotatably coupled about a center joint, each of which is selectively moveable between a first position when the frame is in the erected state and a second position when the frame is in the collapsed state. A purlin assembly has first and second purlin members that are rotatably coupled about a purlin mid-joint. A first end of the purlin assembly is pivotally coupled to the first frame support, and a second end of the purlin assembly is pivotally coupled to the second frame support. The purlin assembly is selectively lockable in an extended position when the frame is in the erected state and is rotatable to a folded position when the frame is in the collapsed state.

Abstract: A compact, temporary shelter that includes at least two vertical frame members aligned transversely over a base frame. Each frame member includes two opposite straight lower sections, two curved eave sections, two optional straight roof sections and a curved, central peak section. Adjacent frame members are interconnected by a plurality of purlins. The shelter includes an inner liner disposed over the inside surfaces of the frame members. The inner liner creates wall air spaces between two adjacent frame members and an upper attic and a lower living space that are partially isolated. When attached to an HVAC unit, air from the living space and flows and circulates into the wall air spaces between the frame members and into the attic. From the attic, air travels through a vent opening formed on an end cover to the outside environment. Located inside the shelter is a flexible air sock that connects at one end to the output port on the HVAC unit to evenly distribute the air into the living space.

Abstract: A large temporary shelter designed to act as a communication, maintenance, and warehouse facility in all types of climate and terrain. The shelter is engineered for durability, portability, repetitive assembly and disassembly. The shelter includes a plurality of lightweight structural arched frame supports that are easy to assemble and connect to a lightweight, rectangular-shaped base frame temporarily attached to the ground. The shelter also includes a durable outer cover and an inner liner that extends over the outside and inside surfaces of the arched frame supports. The outer cover and inner linings are spaced apart to create duct spaces between the arched frame supports for heating air conditioning. A central attic space is created between the outer cover and the inner linings which creates a large central air space for greater insulation. Formed on one end of the shelter are at least one personnel door and two double-hinged vehicle doors.
