  • Patent number: 5950814
    Abstract: A spectacle case (1) consists of two lateral elements (6) and an enveloping element (11) made of an elongated sheet of thin, resilient material having at its one end a section which is bent into cylinder sector form to constitute an end surface (5) of the case, a planar or slightly curved section which forms the bottom (8), a section which has been bent into cylinder sector form to constitute a second end surface (4), a planar or slightly curved section which forms the cover surface (10) and a section at the opposite end of the elongated sheet which has been bent into cylinder sector form to constitute a hooked locking means (9). The two lateral elements are permanently joined with those portions of the elongated sheet which constitute the bottom and the two end surfaces and brace these sections whereby they provide a solid bottom portion of the case. The unbraced portion forms a resilient cover (3) of the case.

  • Patent number: 5920369
    Abstract: A clip-on shield (6) for spectacles (1) adapted for securing shield lenses (7) in front of the lenses (4) of the spectacles is provided with a connecting bridge (8) between the lenses provided with an engagement tongue (12) that engages behind the connecting bridge (3) of the spectacles, and is designed to transmit force from the shield which is oriented centrally relative to the symmetrical plane of the spectacles. The shield is guided by the abutment of a friction surface at each shield lens on the front of the spectacles and optionally by a guide pin (9) at each shield lens, said guide pin engaging with the spectacles. A spring means is arranged to bias the engagement tongue against the back of the spectacle's connecting bridge and the shield lenses towards the front of the frame of the spectacles.
