A UNIVERSAL CONSTRUCTION DEVICES FOR MODELS, STAGECRAFT, MODELS OF MATRICES AND THE LIKE

摘要

A construction apparatus for models, stagecraft, models of matrices and the like. Elements with locations at equal increments construct a mosaic of locations and points in a tetrahedron solid or portion thereof with each selected point in predetermined angular and linear relationship to every other selected point in the mosaic. A selected ratio in size constructs a scale model of a full-size structure with corresponding mosaics. Components rotate at any location. Adjustable elements select any point in relation to said mosaic. Any component is movable to any corresponding location in said mosaic. An integral connector may include two parts facing outwardly on opposite sides of a location. First part includes a resilient snap-ring (2'-a-4) in a retaining groove (2'-a-3) adjacent to a polygonal recess. The first part engages a second part with a polygonal protrusion (3'-a-7) at a location in a second element. The edges of said protrusion expand said snap-ring to engage the two parts in a predetermined orientation. By minimizing frictional wear between the connector faces in engaging, the elements have lifetime durability. An integral connector facilitates construction of regular polygons in assembly and disassembly, with stability, accuracy, and ease of alignment of the elements. A connector does not depend upon gravity for engagement and therefore is adapted for use in non-gravity situations. Connectors include triangular, hexagonal shapes, and subconnectors rotatable 360 degrees, selectively integral with and at each location.
