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.

Claims

1. 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.

2. A mobile geometrical form as in claim 1, wherein said geometrical form is comprised of a double sided continuous strip of material, a first side of each of said helixes facing in a common axial direction and a second side of each of said helixes facing in the opposite axial direction, and wherein the first side of one of said helixes continues to the second side of the other said helix.

3. A mobile geometrical form as in claim 2, wherein both of said helixes are of substantially the same radius.

4. A mobile geometrical form as in claim 2, wherein said helixes are out of phase with each other.

5. A mobile geometrical form as in claim 2, wherein each of said twisted loops extends axially and has a point of inflection at the top thereof.

6. A mobile geometrical form as in claim 2, wherein said strip of material is made of a semi-rigid flexible material, said strip assuming the geometrical form in an infinite number of relative positions of said strip, the stresses established in said strip redistributing themselves in each relative position of said strip to maintain the shape of the geometrical form.

7. A mobile geometrical form as in claim 6, wherein said material is a sheet of metal.

8. A mobile geometrical form as in claim 6, wherein said material is a sheet of elastomeric plastic.

9. A mobile geometrical form as in claim 1 and comprised of a series of interconnected annular discs each having first and second opposing surfaces, the discs being interconnected so that the first surfaces form a continuous connection and the second surfaces form a continuous connection.

10. 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.

11. A mobile geometrical form as in claim 10, wherein said internal edge is smooth.

12. A mobile geometrical form as in claim 10, wherein said strip of material is of uniform width.

13. A mobile geometrical form as in claim 12, wherein said external edge has a predetermined length, and wherein two extensions are placed at points along said predetermined length to form therebetween two equal length portions.

14. A mobile geometrical form as in claim 10, wherein said anchoring means comprises passageway means axially extending through a diametric plane of said tube.

15. A mobile geometrical form as in claim 14, wherein said passageway means comprises a transverse channel extending from one edge of said tube.

16. A mobile geometrical form as in claim 14, wherein said passageway means comprises a transverse bore through said tube.

17. 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.

18. A mobile geometrical form as in claim 17, wherein both of said helical portions are of substantially the same radius.

19. A mobile geometrical form as in claim 17 and wherein said geometrical form is comprised of a double sided continuous strip of material, a first side of each of said helical portions facing in a common axial direction and a second side of each of said helical portions facing in the opposite axial direction, and wherein the first side of one of said helical portions continues to the second side of the other said helical portions.

20. A mobile geometrical form as in claim 19, wherein said strip of material is made of a semi-rigid flexible material, said strip assuming the geometrical form in an infinite number of relative positions of said strip, the stresses established in said strip redistributing themselves in each relative position of said strip to maintain the shape of the geometrical form.
