  • Resilent hinge for spectacles frame utilizing a knuckle which includes recessed portions to define two positions of a side-arm
    Patent number: 5975693
    Abstract: The present invention relates to a resilient hinge which includes a front knuckle fixed to a front lug and an arm knuckle fixed to an arm. The two knuckles are connected by a hinge pin and have two contacting faces perpendicular to the hinge pin. The contacting face of one of the two knuckles has at least one raised portion with an oblique side interacting with one or more recessed portions of the contacting face of the other knuckle. The knuckles move in relation to each other along the connecting hinge pin and against the force exerted by a resilient device coaxial with the hinge pin when the raised portion leaves the recessed portions in the event of the arm rotating with respect to the front lug.
