Novel system for mounting sidearms on spectacles

A rimless spectacle side arm mounting system, characterised in that it comprises a screw (2) installed approximately horizontally and approximately parallel to the “plane” of a lens (1), the thread on which is pointing to the outer edge of the lens (1), is free to cooperate with a nut (18) and is proud of the edge of the lens (1).

A spectacle side arm, characterised in that it is made of cord (20, 21) and in that it comprises a nut (18) in the form of an internally threaded dowel, one end of which is practically closed whilst still leaving room for the cord (20, 21) to pass through, the end of which on the side of the dowel (18) has a wider part to lock it in the dowel (18) whilst still leaving the dowel free to rotate.

A spectacle side arm, characterised in that it is of a rigid or semi-rigid type (14), its end on the side of the spectacles comprises two right-angled extensions (16, 17), a nut (18) mounted rotating freely around the side arm (14) being installed at the level of the first extension (16), and the central axis of the nut (18) is installed perpendicular to the length of the side arm (14).
