Mechanical tilt coupling

Claim 1

A TILT COUPLING FOR ATTACHING A DEVICE TO A SUPPORT TO PROVIDE FOR UNIVERSAL TILTING OF THE DEVICE WITH RESTRAINT TO AXIAL AND TORSIONAL FORCES DERIVED FROM THE DEVICE COMPRISED OF: UPPER ATTACHMENT MEANS HAVING A CIRCULAR FLANGE FOR ATTACHMENT TO SUPPORT MEANS, LOWER ATTACHMENT MEANS HAVING A CIRCULAR FLANGE FOR CONNECTING TO A DEVICE FROM WHICH AXIALLY-UPWARD AND TORSION FORCES ARE DERIVED, SAID LOWER ATTACHMENT MEANS BEING VERTICALLY SPACED FROM SAID UPPER ATTACHMENT MEANS AND ARRANGED SO THAT SAID FLANGES ARE PARALLEL TO EACH OTHER, CYLINDRICAL LATTICE SPRING MEANS EXTENDING BETWEEN SAID FLANGES, SAID UPPER ATTACHMENT MEANS HAVING TRUNNION STRUCTURE EXTENDING AXIALLY AND DOWNWARDLY WITHIN SAID CYLINDRICAL LATTICE SPRING MEANS AND PROVIDING A LOWER CONVEX SURFACE CENTERED ON THE AXIS OF SAID CYLINDRICAL LATTICE SPRING MEANS AND FACING DOWNWARDLY, SAID LOWER ATTACHMENT MEANS HAIVNG ROCKER STRUCTURE EXTENDING UPWARDLY WITHIN SAID TRUNNION STRUCTURE AND PROVIDING AN UPWARDLY-FACING UPPER CONVEX SURFACE CENTERED ON THE AXIS OF SAID CYLINDRICAL LATTICE SPRING MEANS, ROCKER MEANS PROVIDING AN UPPER CONCAVE SURFACE AND A LOWER CONCOVE SURFACE, SAID UPPER CONCAVE SURFACE OF SAID ROCKER MEANS FACING SAID UPPER CONVEX SURFACE OF SAID LOWER ATTACHMENT MEANS AND HAVING RADIUS SLIGHTLY LARGER THAN SAID UPPER CONVEX SURFACE TO PROVIDE LIMITED ROLLING ON SAID UPPER CONVEX SURFACE, SAID LOWER CONCAVE SURFACE OF SAID ROCKER MEANS FACING SAID LOWER CONVEX SURFACE OF SAID UPPER ATTACHMENT MEANS AND HAVING A RADIUS SLIGHTLY LARGER THAN SAID LOWER CONVEX SURFACE TO PROVIDE LIMITED ROLLING ON SAID LOWER CONVEX SURFACE, SAID LATTICE SPRING AND SAID CONVEX AND CONCAVE SURFACES BEING SO DESIGNED THAT A RELATIVELY SMALL FORCE IS REQUIRED FOR INITIAL TILTING OF SAID LOWER ATTACHMENT MEANS WHEN SUBJECT TO AN UPWARDLY-DIRECTED FORCE SINCE SUCH FORCE CAUSES ROLLING OF SAID CONCAVE SURFACES ON THE RESPECTIVE FACING CONVEX SURFACES FOR FURTHER TILITING AND EXTENSION AND COMPRESSION OF SAID LATTICE SPRING, AND SAID LATTICE SPRING PROVIDING RESTRAINT TO TORSIONAL FORCES ACTING ON SAID LOWER ATTACHMENT MEANS.
