Abstract: An erectable tent structure is formed by a flexible roof covering that includes a central portion and a plurality of ridge portions that have inclined slopes and that extend along ridgelines radially outwardly and upwardly from the central portion to terminate in peaks located at the periphery of the roof covering. the slopes thus form valley portions between the ridgelines, and the valley portions have valley floors that slope radially outwardly and downwardly from the central portion. A support pole supports the roof covering at reach peak, and anchor structures secure the flexible covering to the support surface in a manner that a ridge tension force is applied upwardly and outwardly along the ridgelines and a valley tension force is applied downwardly and outwardly along the valley floors. The ridge and valley portions may be formed by joined panels so that there is a primary seam along each ridgeline and a secondary seam along each valley floor.

Abstract: The structure is adapted for frequent set-up and takedown and is designed to avoid roof sag and pocketing. The structure includes a framework having plural vertical supports and plural horizontal supports bridging between adjacent vertical supports. A removable roof cover is dimensioned to extend over and removably attached to the structural framework, and defines plural corners, with each corner positioned at an intersection of a horizontal support and a vertical support so as to define an intermediate roof field between adjacent corners. The vertical supports include elevated curves for lifting the corners of the roof cover, so as to form the intermediate field in a trough, the peripheral hem of the roof cover being removably attached to the vertical supports to draw the roof cover taut across the intermediate field and thereby avoid roof sag and pocketing.

Abstract: A portable canopy structure may be erected from a collapsed state to an expanded state that shelters a desired surface. The canopy structure includes a dome-like covering that is held in position by a support framework having a plurality of upright support members that are interconnected by a plurality of scissor assemblies. Each upright support member slideably mounts a slide bracket, and a rigid bracket is mounted at its top. The scissor assemblies are connected to these brackets. Preferably the structure is in the form of a parallelepiped, and an internal scissor assembly extends between two facing side scissor assemblies which interconnect the upright supports. The covering extends across the tops of the supports and has side panels which depend downwardly from its perimeter, and the internal scissor assembly supports a central post that helps support the covering. A screen may be positioned around the support structure and may be connected to and be downwardly dependent from the side panels.

Abstract: Significant, life-saving protection from airborne, radioactive (fallout) particles due to nuclear explosions, nuclear reactor accidents, and other releases of radioactive particulate is provided by a double-wall tent structure quickly erectable over a central bench or hole. The tent structure includes tightly woven, rip-resistant fabric panels supported by tensile rods or wands, a tub floor extending into and lining a central trench or hole, and an exterior, light-reflecting, metalized, semi-transparent disposable membrane. The bottom circumferential edge of the outer membrane extends into a shallow trench or ditch, excavated around the perimeter of the inner tent structure. Dust particles settling onto the smooth exterior surface of the membrane slide off and are captured in the shallow ditch, thus minimizing direct or indirect radiation into the central trench or hole and its occupants.
