Description

Bloccaggio a molla per lenti su glasant La caratteristica di un occhiale ,vista o sole ,Glasant ,è quella d'avere la parte centrale(naso)e le parti laterali(musi)attac= cati direttamente alle lenti od ai filtri da sole ,per mezzo di perni filettati innestati direttamente sui fori realizzati sul= Le succitate lenti e bloccati per mezzo di piccoli dadi.Questo sistema presenta l 'inconveniente della frequente perdita dei piccoli dadi e,conseguentemente, delle lenti.E' inoltre impos sibile stringere in modo molto forte i dadi senza incorrere nella non infrequente rottura delle lent e nella impossibili= tà in tal caso,di togliere e rimettere il dado a causa della bava prodotta dal taglio della parte ilettata sulla quale è avvitato i dado .Tale inconveniente viene eliminato con il montaggio del Bloccaggio a molla costituito da parti completa mente in acciaio inox .(La parte filettata,la filettatura ,il bulloncino e l'avvitatura dello stesso nei fori predisposti nelle lenti,viene così eliminata ).Le parti elastiche ,in ripo so,hanno una divaricazione maggiore,di alcuni gradi, rispetto alle stesse parti una volta inserite nei fori.Pertanto,una volta inserite,si contraggono tendendo alla posizione origina= le e bloccando,in tal modo ,le lenti .Un tubetto calibrato e termo astringente evita il contatto della parte tagliata colviso o coi capelli.Anche la eventuale sostituzione di una o di ambedue le lenti è estremamente semplificata. La rondella plastica può essere inserita nel foro della lente o può esse= re applicata sul perno passante della lente Spring locking for rimless lenses The characteristic of a glasses, sight or sun, Glasant, is to have the central part (nose) and the side parts (faces) attached directly to the lenses or sun filters, to by means of threaded pins engaged directly on the holes made on the aforementioned lenses and blocked by means of small nuts. This system has the drawback of the frequent loss of small nuts and, consequently, of the lenses. the nuts without incurring the not infrequent breakage of the lenses and the impossibility in this case, to remove and replace the nut due to the burr produced by the cut of the threaded part on which the nut is screwed. This inconvenience is eliminated with assembly spring locking made up of parts completely in stainless steel. (The threaded part, the thread, the bolt and its screwing in the holes provided in the lenses, is thus eliminated The elastic parts, when resting, have a greater spread, by a few degrees, compared to the same parts once inserted in the holes. , lenses. A calibrated and thermo-astringent tube avoids contact of the cut part with the face or with the hair. Even the possible replacement of one or both lenses is extremely simplified. The plastic washer can be inserted in the hole of the lens or it can be applied on the through pin of the lens

Claims

CLAIMS The following claims are hereby set out on the Spring Lock for lenses on Glasant spectacles. 1 ° -Four grafts (Dis.1-Dis.4 - A'.A ", two on the faces and two on the nose) stainless steel replace the threaded pins that are the basis of the realization of a Glasant eyewear (Eyewear equipped only with the central and of the two lateral parts applied directly to the lenses without the presence of the lens containment circles). 2 ° -The fork couplings (Dis.l-Dls.4-A ', A ") have a gap in the rest position (Dis.1-distance between A' and A") a few degrees higher than that of the position of use (Dis.4-distance between A'and A ") and once inserted into the lenses they create a tension that keeps the lenses stable. 3 ° The lenses are drilled (Dis.2-holes B 'and B ") according to the scheme supplied with the glasses, in order to avoid any errors. 4 ° - The parts of the glasses that engage in the lenses (Dis.l-A1, A ") are equipped with tubes or washers (Dis.3-washers D) in thermo-astringent plastic material that can be applied externally on the tips of the couplings (A ', A ") protruding from the lenses or on the entire part of the forks (A', A") so as not to allow metal contact with the skin or hair (women's frames). 5 ° - The holes (B1, Bn) of the lenses (Dis.

2 Dis.4-B) can be direct or flared according to the type of lens, its material or its thickness.
