Abstract
Abstract In a spectacles frame of the kind comprising a face and sidepieces each connected to the face by a hinge having first and second hinge knuckles connected together by a hinge pin, the first hinge knuckle being secured to a first one of the two parts consisting of the frame and a side-piece and the second hinge knuckle being secured to the second of the two parts, in which the first hinge knuckle is provided with two facets disposed parallel to the axis of the hinge pin, a resilient strip is secured to the second part and has a free end bearing against one or other of the two facets of the first hinge knuckle depending on the relative angular orientation of the first and second parts about the hinge pin, and the pivoting movement of the side-piece away from the face of the frame about the hinge pin is limited by the resilient strip being pushed by the first hinge knuckle into engagement with the second hinge knuckle.
