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: Shade shelters for reducing air conditioning loads of an associated shelter are provided. The shade shelters aim to reduce the thermal radiation effects of the sun on associated shelters, such as temporarily erected shelters. The shade shelters can be configurable so that natural convection is advantageously utilized for aiding in reducing heat transfer into the interior space of the associated shelter. The natural convection can be in the form of the “chimney effect” for reducing heat transfer into the interior space of the shelter.
