Abstract
A shock absorbing device having at least one nautilus spring disposed between two members is described. When the members move toward each other, the one or more nautilus coil springs are canted and compressed. The shock absorbing device takes advantage of the unique force-displacement curve of canted springs and reduces bounce back.
Claims6
A shock absorption device comprising:
- a first member movably coupled with a second member;
- a nautilus coiled spring disposed between the first member and the second member;
- and
- wherein the nautilus coiled spring has an axis of compressibility substantially parallel to a tangent formed by a major axis of a lumen of the nautilus coiled spring, and
- wherein the major axis of the nautilus coiled spring forms a spiral.
