Patent ID: 7246900

Claim:
Shock-absorbing mechanism for spectacles wherein an endpiece (E) that is provided extensibley from respective sides of a spectacles front and to a free end of which a temple (T) is connectable is composed by disposing a pair of inner and outer parts made from one of elastic wiring and plating materials in juxtaposition, for said outer part an external member ( 1 ) bent archly being adopted to keep a shape and structure of said endpiece (E) intact and reinforced whereas for said inner part a buffer piece ( 2 ) doubled back into a hairpin shape and comprising at least a first bending portion ( 21 ) of convex shape and a second bending portion ( 22 ) of concave shape being adopted, and upon said temple (T) being unfolded in excess, said first bending portion ( 21 ) and said second bending portion ( 22 ) flexibly bend towards a direction to which said portions ( 21 ) and ( 22 ) expand so as to counterbalance stress to which said external member ( 1 ) is subjected while upon said temple (T) being folded to excess said first bending portion ( 21 ) and said second bending portion ( 22 ) flexibly bend towards a direction to which said portions ( 21 ) and ( 22 ) contract so as to counterbalance stress to which said external member ( 1 ) is subjected, thereby, difference in stress applied and that in expansion and contraction effected between said external member ( 1 ) and said buffer piece ( 2 ) being counterbalanced so as to absorb an external force to which said spectacles are subjected.
