Abstract
This innovation regards a new type of hinge for spectacles that is separable from the ordinary arms, which are therefore interchangeable and to which an adequate elasticity during the process of adjustable and forced widening is guaranteed. The peculiar innovation of this invention is that it is endowed with lugs (A) of the front (C) of spectacles with a slot (8) for elastic means (10) which works on a slider (11) whose hollow (12) is blocked by a ring (3) of an arm (4) and pushed by said elastic means (10) against a front plate (9) of said arm (4) in order to impart the desired reaction force on said arm (4).
