Abstract
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.
Claims3
A construction toy from which tensile integrity structures can be assembled, said toy comprising,
- a. a plurality of telescoping strut members each being composed of two or more generally rigid hollow tubular sections and fitted, at or near each of its ends, with means for attaching one or more flexible tensile members;
- b. a plurality of generally flexible tensile members, each greater in length than the collapsed length of the telescoping strut members, and capable of being attached at an end point to a first telescoping strut member and, at points along its length, to a second and additional telescoping strut members, thereby joining the telescoping strut members in a discontinuous relationship.
A construction toy from which tensile integrity structures can be assembled, said toy comprising,
- a. a plurality of telescoping strut members each being composed of two or more generally rigid hollow tubular sections;
- b. a plurality of generally rigid fastening members, each capable of being inserted and frictionally retained in, or otherwise attached at or near, an end of a telescoping strut member, and additionally fitted with means for attachment to one or more flexible tensile members;
- c. a plurality of generally flexible tensile members, each greater in length than the collapsed length of the telescoping strut members, and capable of being attached at an end point, by means of a fastening member, to a first telescoping strut member and, by means of additional fastening members, at points along its length, to a second and additional telescoping strut members, thereby joining the telescoping strut members in a discontinuous relationship.
