An acoustic shell for stage performances has a frame defining a concave volume that is curved in two orthogonal planes and has an inner surface facing forwardly of a stage for a performance. A plurality of polygonal acoustic panels are positioned in the frame and spaced in rows and column along the inner surface, each panel having an outer acoustically active surface. The frame is formed of plural curved trusses each with a base for support on the stage and a peak. An oculus ring is connected to the peak of each arch and the bases of the arches are space along a bottom curve of the concave volume. The panels comprise plural adjacent blocks in rows and columns, each with a base and inner closed end, the length of each block being different for adjacent blocks.

An expanded kiosk and kiosk system that is collapsible and deployable by expansion and contraction. The kiosk includes a lighting system adapted to provide a light characteristic to the kiosk and represent a lamp post or light post for public or private spaces. Deployment of the kiosk includes moving first and second vertically-oriented structural units away from one another such that one or more of a canopy, a working surface and/or a front-facing surface are fully deployed and the canopy surface and working surface are substantially parallel to one another.

An expandable structure that includes front and rear structural units having inside-facing surfaces parallel to one another, a retractable top that spans the front and rear structural units, and first and second retractable partitions each of which spans and connects the front and rear structural units. The front structural unit is fixably attached to a substrate and the rear structural unit is mounted on a rolling mechanism so that the rear structural unit may be moved away from the front structural unit in an orientation perpendicular to the face of the first structural unit to a distance equivalent to a deployed depth of the first retractable partition, the second retractable partition and the retractable top.

A system and method for primarily erecting curvilinear buildings using a plurality of interconnected structural tubes/sandwich panels is provided. Fabricating structural tubing comprises: connecting a fibrous and flexible lining to an inner surface of a flexible outer membrane, wherein the lining is saturated in a curable material that forms into a solid foam material when cured; and curing the curable material. Fabricating a sandwich panel comprises: connecting a first fibrous and flexible lining to an inner surface of a first flexible outer membrane, wherein the first lining is saturated in a curable material that forms into a solid foam when cured; connecting a second fibrous and flexible lining to an inner surface of a second flexible outer membrane, wherein the second lining is saturated in a curable material that forms into a solid foam when cured; and curing the curable material of the first lining and second linings.

The basin cover having evenly-spaced covering elements mounted to shelf angles along the sides of the basin. These shelf angles are retained by anchor bolts to the inside edge of the rim of the basin. Flat tabs are adjustably spaced apart along the shelf angles and respectively overlap unevenly-spaced anchor retention areas of the basin. The flange portion of the shelf angles extend in a same plane as a walkway along the rim of the basin for widening this walkway. The new cover can be installed to basins of different conditions without major custom work.

An expandable kiosk structure with a front face, a rear face, a first side structural unit and a second side structural unit arranged such that the front face and rear face are parallel and connect the first and second side structural units to form a box shaped structure that is expandable from a collapsed form an expanded form in which the front face, the rear face, and the first and second side structural units define an interior workspace in the box shaped structure. The front and rear faces each have an outwardly extendable portion that is hingeably or pivotally foldable onto a remaining portion of the front or rear face. Rolling mechanisms are disposed bottom corners and extendable brackets are disposed at the top corners connecting to a shading unit supported by a shading unit support structure. Front and rear shelf units are hingeably attached to the front and rear faces. One or more extendable chassis brackets extend along the length of the top and bottom edges of the front and rear faces to permit expansion of the first and second side structural units. The front face chassis bracket is strongly connected to a perpendicular revolving rod handle (trailer coupler) that aids in maneuvering the kiosk prior to attachment to or subsequent to detachment from its towing vehicle as well as during towing.

A collapsible sun shelter that includes an arch support and a rollable flat mat that is configured to expand to include a canopy section and further includes a floor area portion, an upwardly deployable area portion at least two mat anchor points and at least two arch support openings. The rollable mat has an upwardly deployable area portion defined by an outer perimeter passing through at least one layer of the rollable flat mat such that the upwardly deployable area portion remains connected with the floor area portion when the upwardly deployable area portion is extended upwardly in a deployed configuration.

Foldable tubular construct/element with one rigid degree of freedom is of a tubular construction formed by a number of single layered annular units which are connected in sequence; each single layered annular unit is of a prism having N ridge lines; two adjacent prisms each having N sides are connected to each other by sharing a polygon with N sides formed on an intersection plane; each prism with N ridge lines is composed of N rigid planar quadrilateral facets; two adjacent single layered annular units comprise N spherical mechanisms formed by the intersections of only four planar quadrilateral facets at each apex, where N is a number greater than 3.

An expandable shade and shelter system that includes an expandable grid structure of reversibly expandable cells in a two-dimensional grid configured to collapse to a rectangular cuboid with a top surface, an anchored bottom, an anchored first end, an expandable second end, and two expandable sides. The system includes a connecting device fixed at corners of the top surface and/or the expandable second end of the structure, a vertically oriented support structure having a top and bottom ends, where the expandable grid structure is configured to expand upwardly from the second end and inwardly towards the top of the vertically oriented support structure, while the anchored first end remains anchored, to connect the connecting device to the top of the vertically oriented support structure to form a three dimensional shelter.
