The mobile has twelve elongated members positioned with respect to one another to create the appearance of a hexahedron. At each of the eight corners is a flexible joint means joining three rods together and permitting the rods to pivot relative to one another (but maintaining their attachment) so that exterior forces such as air currents or mechanical thrusts cause the mobile to move in an undulating fashion and thereby create changing hexahedron shapes or patterns. The mobile is suspended from a ceiling or from an arm on a stand. Suspension is attained by a pair of threads which are respectively attached to an opposite pair of top members.
An improved folding dome-like modular building structure composed of 48 flexibly interconnected equal right isoceles triangles. Each building structure is formed from a series of four flexibly connected modules of 12 triangles each. The modules are connected in alternating right and left-handed mirror image sequence. Each triangle is defined by struts. The improvements lie in the provision of intermediate cuts and hinged joints in certain of the struts to facilitate folding of the structure into a compact mass. Variations of the basic building structure are disclosed. The building structures may be open or partially open framework or they may be enclosed by a fabric or film covering.
A construction kit consisting of telescoping strut members and pre-measured elastic or inelastic tendons, for the purpose of constructing tensile-integrity structures. The invention is made of reusable elements. By introducing struts which can be adjusted to various lengths the invention circumvents the necessity of measuring, cutting and tying different lengths of tendons for different structures and considerably simplifies the construction process.
A figure for positioning into a variety of polygonal orientations. The figure includes telescoping outer members pivotally connected to one another to form a polygon. The telescoping members can each be adjusted in length and angular orientation relative to adjoining members to form a plurality of polygonal shapes.
A modular elongated element (1), an intramodule tensile device (11), a pair of securing and linking devices (12), and an intermodule connector device (13), interconnected using the devices and methods disclosed herein, are used to construct a virtually limitless variety of inherently-tensile constructs. In the most elemental module, the intramodule tensile device (11) connects a pair of securing and linking devices (12) which are in turn secured to two ends (14) of the modular elongated element (1).
