A channel bar assembly is provided for use with a modular display system. The modular display system can have a display frame that is made up of a plurality of legs that are coupled to a plurality of hubs. The channel bar assembly includes a first channel bar and a second channel bar, each channel bar having a first end and a second end, and a hub connector having a first end hingedly coupled to the second end of the first channel bar, and a second end hingedly coupled to the first end of the second channel bar. The hub connector is connected to one of the plurality of hubs.

A method and apparatus for seismically retrofitting pre-existing household brick chimneys is described to meet current building codes. Vertical steel rebar and horizontal chimney anchors are inserted into the chimney and a polymer concrete is poured between the liner and the brick masonry thereby bonding to the chimney, the vertical steel rebar, and the horizontal chimney anchors. The horizontal chimney anchors are coupled at one end to the external face of the chimney and at another end to the interior frame of the house. Holes are vertically drilled into the masonry of the chimney base in order to anchor the steel rebar at one end. Holes are drilled through the chimney and into the interior of the house at an appropriate point to properly anchor the pre-existing chimney to the house. A polymer concrete that has similar heat properties to other fireplace components is poured into the chimney around a chimney liner in order to reinforce and provide resiliency.

An adjustable support structure for a fireplace including upper and lower bars extending in a longitudinal direction, the upper bar being positioned above the lower bar and including a surface upon which the fireplace can rest. First and second cross bars are also included, each with upper and lower ends, the upper end of the first cross bar being coupled to the upper bar and the lower end of the second cross bar being coupled to the lower bar. The lower end of the first cross bar is moveably coupled to the lower bar and the upper end of the second cross bar is moveably coupled to the upper bar such that the upper bar may be adjusted upwards in a plane with respect to the lower bar to a desired height.

A foldable truss member suitable for commercial displays includes a plurality of side members that are adjacently hinged together. The side members include support members and bridging members having extensions. The side members are joined into a foldable structure with a hinge member between the support member and extensions of adjacent side members. The truss includes a locking frame that is removably attached to ends of the side members. A display structure can be formed by connecting a locking frame between two truss members.

An open-lattice, foldable, self-deployable structure with a number of spaced, bendable longitudinal members each having a curved cross section forming cells each bounded by a portion of two spaced longitudinal members and two spaced diagonal members. The diagonal members are joined to the longitudinal members at the cell boundary intersections of the diagonal members and the longitudinal members. The longitudinal members are made of a material which bends and flattens by a predetermined amount below the material's yield point and the diagonal members are made of a material which both bends and twists by a predetermined amount below the material's yield point so that the structure can be collapsed and then self resurrected.

An apparatus for a pop-up display structure that provides a hub structure that is divided into two sections that are held together by a thumbscrew. The two sections define internal channels in the hub for capturing guide pins attached to the tubes such that the tubes pivot about the guide pins and rotate about the hub through slots in the hub. The thumbscrew provides for removal of tubes from the hub structure without the use of tools and therefore provides for changes on the fly for reconfiguring the structure or for replacing broken tubes. The thumbscrew also provides a mounting structure for the channel bar that attaches to the pop-up structure. The channel bar is capable of folding into three sections and is capable of folding compactly without regard to the sequence of the folds.

A collapsible beam element is provided, including: (a) an elongated flexible structural member having a predetermined cross section; and (b) a hollow defined by the cross section of the flexible structural member, wherein the flexible structural member is collapsible so as to enable folding of the beam element from an open configuration into a packed configuration, and wherein the flexible structural member readopts the predetermined cross section when unfolding the beam element from a packed configuration into an open configuration. The beam element is preferably made of material having predetermined shape. The beam element may be used so as to construct any collapsible three dimensional construction. Amongst other possibilities, the beam element may be used as a stretcher beam or a ladder or bridge beam.

A multi-sectional utility pole includes at least two sections of straight pipe, which are joined and connected by a slip joint connection. The slip joint consists of two mating conical sections, with one attached to each section of the pole. The slip joint is compressed with the aid of rings, which are attached to the pipe, and a key and slot. The conical sections can be swaged from the ends of the pipe, or can be fabricated separately and welded on to the ends of the pipe.
摘要:
A portable, easily composable supporting skeleton which serves as a supporting structure of buildings composable in situ. The skeleton comprises a pipe-like spacer. Two dismountable node plates can be fixed to the spacer by way of clamping assemblies. Each node plate includes an eye having a through-hole. A joint assembly which comprises a crosswise tie-piece can be interconnected pivotably to the through-hole of the eye of one of the node plates.
