Abstract: Sport glasses are disclosed which include a frame having a substantially laterally extending arcuate upper portion, a nose piece integral with and centrally depending therefrom, and a pair of temples, which are hingedly mounted to the frame. A pair of convex lenses are mounted in the frame, each lens having an exposed side edge having a concave portion and an exposed lower edge having a concave portion. When the glasses are worn, the exposed edges of the lenses substantially conform to but are spaced apart from the adjacent facial structure of the wearer. In a preferred embodiment, the lenses are detachable and replaceable by the wearer. In another preferred embodiment, a pair of slots are formed in the upper portion of the frame, providing ventilation and minimizing fogging of the lenses when the sports glasses are worn by the wearer.

Abstract: An adapter consists of a rigid V-shaped angle piece (7), one leg (8) of which is provided with a slit (9) through which the fastening strap of a mask is fed, while the other leg (10) is equipped with hooks (11) to attach it to the side parts of the mask, in such a way that the fastening point of the strap is offset towards the front of the mask--for use with protective masks or goggles.

Abstract: The coupling system 1 is composed of an elongated piece shaped, on one side to form a claw, the members (10a, 10b) of which are designed to grip the end of a side-piece of a pair of spectacles. On the other side, the coupling system bears a double hinge knuckle 12 which can receive a tenon 13 forming a pivot, which penetrates a through orifice 5 provided on the side of the front face 2 of the spectacles and is retained by its anchoring head 17. The central portion 18 of the coupling system, between the claw and the double knuckle, is of lesser thickness, and is thus elastic and deformable.
