摘要： A deployable truss with modified primary orthogonal joints. The construction of these joints causes the center-hinged primary chords on opposite sides of a truss bay to fold inward in a plane orthogonal to the folding planes of the side diagonals while the two secondary chords fold in planes orthogonal to the plane of the in-folding primary chords.This provides for stiffness and stability during deploy and retract. The unique joint configuration permits the truss to deploy one bay at a time in a stable manner while having lateral bending stiffness, and the truss thus can extend and retract in a sequential manner. It can deploy integral flat panels nested between the secondary folding chords, or use cross bracing in lieu of panels. The truss can be triangular, square or rectangular in cross-section. A powered support frame may be used in conjunction with the truss.

摘要： A deployable single truss with folding or removable chordal members and diagonals and orthogonal hinge joints for continuous and synchronous retraction and extension, in straight and curved configurations. One or more endframes may be used to close off or mount one of more ends of the deployable trusses. A primary orthogonal hinge joint is used to connect the chordal members and diagonals of the deployable trusses along each primary chord. A secondary orthogonal hinge joint to connect the chordal members and diagonals of the deployable trusses along each secondary chord.

摘要： A deployable truss that extends and retracts in a stable and synchronous manner, and can deploy integral folding panels. Primary orthogonal joints, each consisting of two hinged halves, connect rotationally to the truss diagonals with an angled fitting. The main hinge pin of the orthogonal joints remains orthogonal to the truss longitudinal axis and remains centered in the folding truss diagonals. Hinge pins of each truss joint are connected by center-folding chords which cause the truss joints of adjacent bays to remain parallel to each other. Folding diagonals connected to the primary joint halves are hinged together, permitting the diagonals on each side of the truss to remain parallel to each as they form the short sides of a rectangular truss. The truss may deploy z-folded panels with active surfaces such as photovoltaic, reflective, heat-radiating, LCD/plasma, or radar; or structural floor panels for folding work platforms, bridges, and walkways.

摘要： A deployable rectangular truss with folding or removable chordal members and diagonals and orthogonal hinge joints for continuous and synchronous retraction and extension. The truss is rectangular in cross section, with four common chords on the corners. Two opposing sides of the truss have diagonals that meet at side joints. One or more end frames may be used to close off or mount one of more ends of the deployable truss. A plurality of telescoping transverse struts may extend between major joints on one side of the truss.

摘要： A mounting mechanism for an endless traction band system in which the endless band is supported on and driven by a pair of laterally spaced roller chains. The mounting mechanism supports a double sprocket for engaging the chains and is adapted to permit a limited degree of skewing by the sprocket wheel shaft so as to maintain the sprockets in alignment with the roller chains even when the roller chains are deformed in response to laterally imposed loads.
