Invented by Italian designer Guido Medana, the SPINE hinge is a result of Guido’s lifelong career in engineering. Drawing from his expertise in a myriad of technical fields, SPINE is his ultimate solution to hinge design in the optical world.
The spun wire cable is the heart of the SPINE hinge. It’s diameter is a mere 0.60mm and at full tensile strength can hold over 300kg. The dual springs not only provide the pulling power of SPINE, but they allow the articulation of the vertebrae and enable our unique auto-shut mechanism.
There are 5 working SPINE vertebrae constantly interacting seamlessly with each other to create a 90 degree hinge opening. As every element helps the other to take the strain, they rotate only 18 degrees meaning they share the load, making wear from friction virtually non-existent.
There are no screws loose here – because there are no screws used in SPINE working mechanics. Accidental impacts are glanced off as SPINE moves in all directions, absorbing and dissipating shocks thus greatly reducing breakage.
