Definitions

  • the present invention concerns a system for constraining lenses in an eyeglass frame, as well as an eyeglass frame specially designed to best exploit such a system.
  • the purpose of the present invention is to avoid the aforementioned drawbacks, offering a system that is cost-effective to product, without mechanical machining such as welding, gluing, perforation, screwing; all of this is obtained by sheet moulding, through laser cutting, or else through chemical milling.
  • the purpose is also to offer a system that is simple to mount and dismount, both in the factory assembly step and in the optician's shop, during the mounting of the lenses of the end user and, not to be underestimated, with the possibility of mounting a single lens at a time, thanks to the double fastener, one for each lens.
  • a system for constraining the lenses which comprises a nosepad-carrying fastener that, being hinged at a point of the metallic frame at the lower bridge, rotates and locks another portion of the frame itself, opposite the first, clamping around the lens contained in it

  • Fig. 2 is a top view of a lens;
  • Fig. 3 is an enlarged view of the pad-carrying fastener with the hook closed
  • Fig. 4 is a top view of the frame with the lenses inserted, but with the pad- carrying fasteners not closed;

  • Fig. 9 is an internal perspective view of the half-frame with the lens inserted and pad-carrying fastener being closed, with the area configured like an elastic element in the foreground;
  • Fig. 10 is a perspective view of the complete frame assembled with the lenses inserted and the pad-carrying fasteners being closed.
  • Fig. 1 illustrates just a part of the frame M and a single pad-carrying fastener G, with it being understood that the other part is absolutely symmetrical.
  • the frame M in its left part has an area C configured like an elastic element, whereas in the right part a half of the upper bridge P is represented, with a throat

  • Fig. 3 illustrates an enlargement of the pad-carrying fastener G, having the hook
  • Fig. 4 illustrates the complete frame M with the lenses L inserted, but with the pad-carrying fasteners not fastened to the upper bridge; thanks to the elastic nature of the frame M and the groove L' made in the lenses themselves, they can stay in their seat even if not rigidly locked by the pad-carrying fasteners (useful function whenever the lenses have to be correctly oriented before they are locked).
  • Fig. 5 illustrates the first insertion procedure of the pad-carrying fastener G in the half-frame: the pad-carrying fastener G is positioned by matching up the hooked semicircular area G', in the respective receiving area Q' of the lower bridge Q of the half-frame; once the pad-carrying fastener G has been inserted according to the procedure described above, the hook G' will be closed with a simple mechanical operation, according to what is illustrated in fig. 3, thus allowing it to rotate but not to detach. Once locked, it will be made to rotate, according to the direction of the arrow F.
  • Fig. 6 illustrates the first part of rotation of the pad-carrying fastener G according to the direction of the arrow F': in the first part of rotation the pad- carrying fastener G, hinged in the area G' rotates around the receiving area Q', entering into the throat P' of the upper bridge P, made easier by the curvature in its portion G'".
  • FIG. 9 illustrates the half-frame assembled with the lens and the pad-carrying fastener, highlighting the area configured like an elastic element C, suitable for compensating for possible size differences of the lenses L.
  • fig. 10 represents the complete frame with the lenses inserted and locked by the pad-carrying fasteners G.

Abstract

L'invention porte sur un système pour maintenir des verres dans une monture de lunettes. Le système comprend une monture monolithique ouverte en son centre, équipée, aux deux extrémités, de deux éléments élastiques, équipée en son centre de deux organes de fixation portant des tampons, ayant une région en forme de crochet, qui s'articule dans des sièges appropriés à proximité du pont inférieur de celle-ci, qui, en se fixant dans des sièges appropriés formés à proximité du pont supérieur de la monture elle-même, verrouillent de façon rigide deux verres, équipées de deux rainures qui viennent en prise avec la monture elle-même.
