In an eyeglass frame each lens is gripped between a relatively rigid half-rim and a filament. The half-rim is fixed to a tenon in which is formed a cavity opening through an orifice forming a keyhole slot. The filament includes a knot retained in the cavity by the keyhole slot.

Eyeglass frame

An eyeglass frame has rims or surrounds at least locally made from a relatively rigid material. They have in transverse cross-section over at least part of their length a U-shape profile with a median part and side flanges. A strip of relatively flexible material is associated with each rim or surround and is disposed between it and the respective lens. The median part of the profile of the rims or surrounds has an increased thickness in its median area.

An elongate deformable structure, that can be used as part of an eyeglass frame, for example, comprises a central core member made from a shape memory alloy. A plurality of annular members are threaded onto the core member. At least one of the annular members has at least one transverse surface disposed obliquely to the axis of the bore through it.

Elongate deformable structure and applications to eyeglass frames

The invention applies to a device for mounting a nasal rest pad on a support member integral with a rim or eyewire of a spectacle frame, comprising a resilient piece that is drawn out in order to be passed in a loop of the arm and in an ear of the pad, and this piece is thereafter released and constricted in the loop and the ear, thus assembling the rest pad to the support arm and the device is applied to a spectacle frame automatically adapted to noses of various shapes.

Process and device for mounting a nasal rest pad and spectacle frame for

Spectacle frame comprising two eyewires associated by at least one assembly bar, wherein each of the eyewires comprises in the nasal rest zone of the frame at least one projecting element adapted to be secured in the wall of a saddle bridge in order to maintain it hooked to the said spectacle frame, and having application to the rapid, reliable and aesthetic fixation of a saddle bridge to a spectacle frame.
