Abstract
A spectacle frame includes sliding hinges which enable the arms to move from a stable open position, in which the end (306) of the arms is parallel to the end (313) of the endpiece (307), to an unstable wide-open position, by pivoting around a support point (311) belonging to a coincidence plane (P,P′) which passes between the knuckles (C1, C2) of the hinges. The frame, which has a plane of symmetry (X,X′), is characterised in that the support point (311) is located closer to the plane of symmetry (X,X′) of the frame than the outer face (309) of the arms at the coincidence plane (P, P′).

A spectacle frame of the type comprising a frame face on which two sides are articulated by telescopic hinges allowing the sides to move
- from a stable open position, in which the hinge-side end, called the “proximal end”, of the sides is parallel and in immediate proximity to the hinge-side end, called the “proximal end”, of a stub forming part of the frame face, the said proximal ends defining a meeting plane, passing between the knuckles of the said hinge,
- to an unstable over-opened position, by pivoting about a bearing point lying in the said meeting plane, the sides having an external surface and an internal surface, and the frame having a plane of symmetry, that is orthogonal to the general plane of the frame face, wherein the said bearing point is located closer to the said plane of symmetry, than the external surface of the sides, measured at the level of the said meeting plane.
