Definitions

  • the present invention is dealt with a new eyeglasses-making method, with a pre-arrangement of a generic front adaptable to all lenses' shape, as well as the association and the hinging of the temples, which are beforehand prepared in order to make eyeglasses completely devoid of any encumbrance about the rimming and without recourse to temples-junction pivots or lens' closing-screws within the front supporting them, as well as new eyeglasses.
  • a first reduction of the eyeglasses' fronts' encumbrances, especially on metal frames, is achieved by the partial removal of eyepieces and by the support and retention of the lenses, by means of a nylon yarn fixed on the arch ends forming the new cut front.
  • This first technique has only partially solved the problem of guaranteeing the best visibility and a reduction of weight and of eyeglasses' encumbrance; moreover, it has highlighted some limits during the assembly phase and about the frames ' durability.
  • An object underlying to the present invention is to put into practice a method, or eyeglasses-making system and eyeglasses, which, notwithstanding the removal of the encumbrance or the view of the eyepieces or the lenses' small control- -rings or rims, can guarantee the utmost simplicity and precision of assembly, with a perfect steadiness and a very durable positioning on the face.
  • Another object underlying to this invention is to remove any need to make holes on the lenses, thus avoiding the well- -known problems about the precision and the difficulties in the making of radial bores.
  • Another object underlying to the present invention is to remove any kind of possible cracking or breaking of the lenses due to the contact between the bolting or the fixing parts passing through the holes on the lenses.
  • Another object underlying to the present method is to allow the optician to build up the eyeglasses by lenses made of any kind of shape, asymmetrical shapes as well, in order to make a great variety of constructive shapes, suitable to and personalised to any request.
  • the peculiarity of the method according to the invention is to provide a phase of forming or moulding of the nose pad, a sort of link-bridge between lenses, having first inserted one smooth flexible wire in the mould, so that its middle can be fixed and firmly associated to the injection of the nose pad, while, during the same phase of moulding, the two smooth ends of the wire are set on the side edges or sides of the bridge-injection area, after having inserted and interposed the respective endpieces placed at the hinging ends of the eyeglasses' temples to be made.
  • a subject-matter of the present invention is an eyeglasses-making method, in which, in a first cycle of operations, a bridge is equipped permanently with a middle of a flexible smooth wire, endpieces of the eyeglasses' temples are put on the ends of said wire, said ends are slipped through the sides of said bridge in order to form a couple of coils or rings, and in which, in a second cycle of operations, lenses are interposed in said coils or rings and fixed therein.
  • said bridge is equipped with nose pads, preferably by injection into a mould, wherein there is a knurled or otherwise rough middle of a smooth wire, sufficiently flexible, whose opposite ends are smooth and lead by suitable spaces within said mould, thereby providing a sliding housing on said sides of said bridge.
  • eyeglasses ' temples endpieces are put on ends of said wire, this phase being carried out before the making of said coils or rings, determined by the introduction of ends into spaces of mould and an adequate projection of them in relation of said middle of said wire.
  • the method according to the invention can be carried out also by means of a pre-moulding of bridge or nose pad, with lid, within which the wire is retained and blocked by a plate equipped with retention-holes.
  • a further subject-matter of the invention are eyeglasses, characterized by comprising a bridge equipped with a flexible wire and having sides in which the ends of said wire are slideably engaged.
  • the eyeglasses are characterized by endpieces provided on said ends of said wire.
  • fig. 1 represents a vertical and in part-section view of the frontal components, which must be assembled according to the present method, as they are given to the optician for the assembly of the lenses which are to be supported and held;
  • fig. 2 represents a particular vertical view of wire 1, which is to be associated to the nose pad or the fixing bridge of the lenses, to make the cited front;
  • fig. 3 represents a vertical view of a couple of lenses, made by a casual model of eyeglasses and equipped with perimetrical chamferring plus external notches, as requested by this method;
  • fig. 4 represents a vertical section view of the lenses in fig. 3 which are put on the parts of the front of fig. 1;
  • figs. 5 to 8 represent the constructive elements of a different bridge or nose pad and by means of which a preliminary variation of the method described is made possible, particularly:
  • fig. 5 represents a perspective view of a bridge or a pre-moulded nose pad, within which the closing wire of the lenses is housed;
  • fig. 6 represents a perspective view of the lid or a closing member of the bridge or nose pad in fig. 5;
  • fig. 7 represents a perspective view of the wire of the lenses, shown in one of its preparation phases
  • fig. 8 represents a vertical view of the bridge in fig. 5 associated to the wire in fig. 7, as well as to the lenses which this wire is to hold. In all the figures the same parts are represented by the same reference numerals.
  • eyeglasses will be made in a preliminary cycle of preparation of generic frames adaptable to any model of lens, put into practice by the eyeglasses manufacturer, and in a final cycle of preparation and application of the lenses, following the model requested by the customer and put into practice by an optician he trusts.
  • said wire 1 is prepared, which, in order to present a better adherence to the material injected in mould S, is first made rough for the knurling, the ashlar-work, the crushing or any other similar well-known system of superficial mechanical transformation of its central part 2, which first is to be bent, as represented in fig. 2.
  • the two parts 3 and 4 of wire 1, sticking out of mould S, are later on bent in the opposite direction to bend 2, so as to form a coil or ring whose ends 3' and 4' are sticking out of the central part 2 and of the edge of mould S.
  • normal eyeglasses' temples are made, with the same wire or with another type of wire, these temples being equipped with hinging ends modelled in shape of a left coiled endpiece 20 and a right one 21, with one or more coils plus a sticking-out part 22, 23, whose function will be illustrated later on.
  • the coiled endpiece 20 of the left temple is put into end 3", so that its projection 22 is turned toward the external part of bend 2, as well as the coiled endpiece 21 of the right temple is put into end 4', so that its projection 23 is turned toward the external part of bend 2.
  • the coiled endpieces 22 and 23 of the eyeglasses' temples have a very small original diameter, and such as to allow only the passage of ends 3 ' and 4 ' , whereon they are respectively hinged.
  • mould S is prepared for the making of a bridge 10, this being carried out by the injection of an adequate material, preferably made of plastic.
  • wire 1 is put into mould S, with the blocking of the knurled bend 2 in the proper upper seat, as well as with the housing of end 3' in casts 13' - 13 ' ' and of the end 4' in casts 14' - 14"', before closing properly said mould S .
  • the first cycle of the present method comes to an end with that injection, and so these are at disposal the eyeglasses frames ready to be sent to the optician, it is to be seen in fig. 1.
  • tracts 3 and 4 of wire 1 are smooth, the adherence of these tracts to bridge 10 is very relative; as a matter of fact, it is sufficient to pull ends 3' and 4' in order to have them slide within bridge 10, with a progressive reduction of the diameter of the coils or rings determined by smooth tracts 3 and 4.
  • the front made by bridge 10 and wire 1 with sliding ends 3 ' and 4 ' is normally delivered to the optician, with a series of couples of templates, every couple of templates reproducing a different model of lenses to put on said front, according to the well-known technique and following the customer's requests.
  • the second cycle of the present eyeglasses front-making method consists of an earlier phase in which the optician, on the stock of the templates given by the manufacturer, cuts out a couple of lenses 30 and 40 each one with an adequate perime- trical chamferring 31 and 41 as well as with external notches 32 and 42.
  • lenses 30 and 40 present reference tracts Rl and R2 , perfectly adherent to seats Rl and R2 of bridge 10, so that it is possible to guarantee a perfect and a steady positioning of lenses 30 and 40 on bridge 10.
  • the optician respectively lines up the chamferring 31 to the plane of coil 3 and chamferring 41 to the plane of coil 4, respectively, after having approximately set coiled and 20 of the left temple on notch 32 of lens 30 and coiled end 21 of the right temple on notch 42 of lens 30.
  • the optician goes on to pull the opposite ends 3 ' and 4 ' of wire 1, making them slide within their smooth seats on bridge 10, until smooth tracts 3 and 4 of wire 1 are completely housed in chamfers 31 and 41 of lenses 30 and 40.
  • hinging endpieces 20 and 21 of the eyeglasses' temples perfectly place themselves within notches 32 and 42 of lenses 30 and 40, guaranteeing the correct arrangement position of the eyeglasses on the face according to what has been established by the manufacturer during his pre-arrangement of the template referring to the chosen lenses' model.
  • Sticking out tracts 22 and 23 of endpieces 20 and 21 are advantageously placed so that the largest divarication of the respective temples can be delimited because of their contact with lenses 30 and 40, while during the phase of closing the temples said sticking out tracts do not bother at all, being of the smallest encumbrance as well as being adequately rounded.
  • a eyeglasses-making method can be carried out which, though it removes the encumbrance and the view of the rims of the lenses, can guarantee the utmost simplicity of manufacturing and an assembly precision, in order to obtain an ideal and durable position of the eyeglasses in accordance with the main object of the invention.
  • the cited method allows the removal of any lenses' bores, as well as any danger of splitting or breaking of the lenses provoked by the presence of boltings, in accordance with other cited objects.
  • a bridge or nose pad 100 is pre-moulded in an adequate material, so as to present, by the sustaining pad-plates 101 and 102 on the nose of the person, an horizontal body 103 whereon a hollow space 104 is obtained, as well as a curved transversal groove 105 and two curved vertical grooves 106 and 107.
  • Bridge 100 is completed by adequate devices of guide and pin (barbing) 108 with its lid 110.
  • This lid 110 is equipped with a superior projection 111 suitable for its housing into space 104 of bridge 100, as well as with adequate guides or pins (barbings) 109 to couple with guides 108 of bridge 100, in order to obtain the best solidity of the two parts.
  • ends 3' and 4' of wire 1 pass through control-holes 121 and 122 of a plate 120 which is housed at the bottom of space 104.
