  • Adjustable spring-loaded hinge device, particularly for spectacle frames
    Patent number: 4793024
    Abstract: The hinge device comprises a recess formed in the rod or stem of a pair of spectacles and accommodating a leafspring. The spring has a conformation such that it pivots on the inner surface of the recess and cooperates with an element, rigidly associated with the front of the spectacles and pivotally connected to the rod. An adjustment screw is provided which extends into the recess and which interferes with the spring to vary the biasing action exerted on the element, when rotating the rod relatively thereto.
