Abstract:
An elastic frame structure comprisinga first planar part having a planar structure formed of a flat disk having a continuous periphery, having a first center opening and having a first substantially radial overall straight cut connecting the continuous periphery to the center opening and defining a first end and a second end of the first planar part with a first middle section disposed between the first end and the second end;a second planar part having a planar structure formed of a flat disk having a continuous periphery, having a second center opening and having a second substantially radial overall straight cut connecting the continuous periphery to the center opening and defining a third end and a fourth end of the second planar part with a second middle section disposed between the third end and the fourth end;wherein the first center opening is of sufficient size as to allow a bending of the first planar part such that tangential planes of the first end and of the second end are disposed perpendicular to tangential planes in the first middle section and such that a first face derived from a first side of the first planar part at the first end is disposed opposite to a second face derived from the first side of the first planar part at the second end of the first planar part;wherein the second center opening is of sufficient size as to allow a bending of the second planar part such that tangential planes of the third end and of the fourth end are disposed perpendicular to tangential planes in the second middle section and such that a third face derived from a first side of the second planar part at the third end is disposed opposite to a fourth face derived from the first side of the second planar part at the fourth end of the second planar part;wherein a first edge of the first end and a third edge of the third end are joined abutting together such that the tangential planes of the first planar part at the first end and of the second planar part at the third end substantially coincide;wherein a second edge of the second end and a fourth edge of the fourth end are joined abutting together such that the tangential planes of the first planar part at the second end and of the second planar part at the fourth end substantially coincide.
