Abstract: The spectacle frame with detachable elements comprises an upper bar, to which two temples are hinged; the bar is laterally provided with first temporary engagement seats either for possible elements for ventilation and connection to a lens pair or, alternatively, for connection to a single lens. The upper bar is furthermore provided with second temporary engagement seats for a lower supporting bar for the lens pair or for the single lens. Engagement means furthermore protrude from the upper bar or from the lower bar and removably engage complementarily shaped grip means which are associated with the lower or upper bar. Means are finally provided for allowing the temporary mutual safety locking of the engagement means and of the grip means.

Abstract: The sunglasses structure comprises a front piece, an arm hinged to each end of the front piece, and a one-piece lens supported by the front piece. A milling is formed in the lens which is substantially V-shaped, with inwardly protruding coupling elements. A V-shaped elastically deformable bridge is insertable into the milling. The bridge has a perimetral groove for accommodating a perimetral portion of the milling and a plurality of seats accommodating the coupling elements, which snap into engagement with the seats upon inserting bridge into the milling. Air vents are provided at a lateral portion of the lens for preventing misting.

Abstract: The hinge structure has the peculiarity of being constituted by an elastically compressible bellows-like element which comprises lugs for temporary coupling to the frame and to a rod. The rods are biased to a position adjacent to the lens of the frame in case of non-use.
