Abstract
A mobile geometrical form having two helical sections interdigitally wound into each other about a common axis. The helical sections are of substantially the same radius and are out of phase with respect to each other. Each end of one helical section continues into a twisted loop, which in turn continues into the adjacent end of the other helical section to thereby form a unitary structure. The geometrical form is comprised of a double sided continuous strip of material. Optionally, a tube axially extends through the helical sections and serves to anchor the loops at either end in spaced apart relationship, while permitting translatory motion of the unitary structure therethrough.

A mobile geometrical form comprising first and second axially extending helixes interdigitally wound into each other, each end of one of said helixes continuing into a respective twisted loop which in turn continues into an adjacent end of the other of said helixes to thereby form a unitary structure, a tube axially extending through said helixes, and anchoring means on said tube for retaining said loops in axially spaced apart relationship while permitting translatory movement therethrough.
A mobile geometrical form comprising first and second axially extending helixes interdigitally wound into each other, each end of one of said helixes continuing into a respective twisted loop which in turn continues into an adjacent end of the other of said helixes to thereby form a unitary structure, said continuous strip of material having both an external edge and an internal edge, said internal edge forming an opening centrally of said form, a tube axially extending through said opening, and anchoring means on said tube for retaining said loops in axially spaced apart relationship while permitting translatory movement therethrough.
A mobile geometrical form comprising a first helical portion and a second helical portion, both said portions being concentric about a common axis and having the same direction of rotation, and being out of phase with each other, adjacent ends of said helical portions being coupled together by means of a twisted loop at each of said adjacent ends, a tube axially extending through said helical portions, and anchoring means on said tube for retaining said loops in axially spaced apart relationship while permitting translatory movement therethrough.
