Device for attaching a removable auxiliary face, especially one having sun-screening lenses, to a spectacles frame

摘要

The device is provided for attaching, to a conventional spectacles frame equipped with two main optical lenses, a removable face (1) possessing, joined by a bridge (10), two auxiliary sun-screening lenses (11, 12). The device includes, for each auxiliary lens, such as (11), two clips (fasteners) (21, 23) fixed to the periphery (13) of the auxiliary lens (11) and substantially normal to the latter, one (21) on the upper edge and the other (23) on the outer lateral edge. The clips (21, 23) each have a transverse notch (25) which will be engaged over the edge of the facing main lens. The elasticity of the clips (21, 23) ensures the retention of the face (1) on the main frame, and the auxiliary lenses (11, 12) do not come into contact with the main lenses. <IMAGE>
