Abstract: An eyeglass frame particularly suited to sporting activities has two temples each comprising a main part and an end part aligned with the main part. The end part is mounted at one end of the main part and adapted to rotate about its own axis relative to the main part. The end part has two opposite edges on respective sides of its rotation axis. One edge has a more accentuated curvature than the other.

Abstract: An eyeglass frame comprises two surrounds each receiving a respective lens. A bridge joining together the surrounds comprises a generally omega-shaped spring. This has two lateral lugs by each of which it is attached to a respective surround. Its middle part has two ends with concave sides facing towards each other and set back relative to the lateral lugs. A nose-side support arrangement is fitted to the bridge and comprises a U-shaped support having two branches each of which is interlocked with a respective end of the middle part of the bridge.

Abstract: This frame, comprising for each of the lenses to be supported an open metallic eye-piece and of which the ends are adapted to abut one against the other by means of a mutually screwing member is characterized in that the two ends of the metallic eye-piece cooperate with a common guiding groove provided in a connecting lug so that, by relative engagement of its ends in the groove, they are perfectly aligned one in the extension of the other.

Abstract: The front assembly of an eyeglass frame comprises two rim members. Each of these is adapted to hold a respective lens. The two rim members are joined together by a bridge member. Each rim member comprises at least one part made from a shape memory alloy and a main part made from a neutral material.

Abstract: An eyeglass frame comprises a variable length member made up of two parts adapted to be inserted one inside the other to a variable distance. At least one shape memory alloy ring or sleeve member is mounted on one of these two parts. The ring or sleeve member is adapted to immobilize the two parts relative to each other at ambient temperature.

Abstract: Spectacles formed by combining two separate parts, respectively, a support structure connected to spectacle temples and a detachable front.A bridge of the front is adapted to be joined to the central part of the support structure connecting the two spectacle temples through the intermediary of a assembly element. Each of the edges of the front is adapted to be connected to the support structure close to its connection with the temples through the intermediary of a projecting assembly element cooperating with a hold-back device and a housing.Application to the realization of the connection of a front and a support structure ensuring good interlocking and insertion of the hooking elements in the overall aesthetic appeal of the spectacles.

Abstract: The present invention relates to a support structure for a spectacles frame and a front intended to be adapted thereto. The support structure comprises a locking arm or shutter movable in rotation between an open position where it allows to penetrate the projecting element of the front in an interacting hollow housing and a locking position where it is folded back in order to block this projecting element. Application to the realization of spectacles frames having detachable fronts.

Abstract: In a spectacle frame each lens surround is formed by a relatively rigid rail and a flexible retaining member attached at each end to the rail. To effect this attachment the ends of each rail are formed with two transverse holes through which the flexible retaining member is passed twice. Each nose pad of the spectacle frame is also formed with two transverse holes through which the flexible retaining member may be passed twice. The holes in each nose pad correspond to those in the nose end of the associated rail, so that the nose pad may be attached to the rail by means of the flexible retaining member holding a lens in position in the surround.

Abstract: The invention relates to a spectacle frame of the kind comprising a main structure (10) and, for each lens (11) to be mounted, a surround which is formed, on the one hand, from an upper rim (12), and, on the other hand, from a flexible rim cord (13).According to the invention, for at least one of the ends of the said flexible rim cord, four holes are provided in combination, two holes (14) being formed in the main structure (10), and two holes (26) being formed in correspondence in the upper rim (12), so that the said rim cord (13) fastens this upper rim (12) to the main structure (10).

Abstract: The invention relates to an improvement to spectacle frames, and is more particularly directed to a novel nose plate holder which comprises a fixing tab adapted to be attached to the spectacles, an upright member adapted to support the side members of the frame and having a length at least equal to twice the thickness of said side members, a substantially U-shaped bow portion having its open end directed downwardly, and a plate attaching member adapted to support the nose plate, said fixing tab, upright member, bow portion and plate attaching member being substantially disposed in line.
