Definitions

  • the present invention relates to eyeglasses of the kind which comprises a frame having a front that is at least partially formed by metal wire shaped by plastic deformation.
  • Background art It is known that eyeglasses in which the structure is provided by means of shaped metal wire are currently particularly appreciated owing to their low weight combined with great mechanical strength.
  • models of eyeglasses which comprise a front at least partially made of metal wire are currently increasingly widespread.
  • the metal wire is usually shaped so as to form the eyewires for supporting the lenses, which are currently installed substantially by elastic forcing of said eyewires, which are provided so as to form a closed loop.
  • the frame and the lenses In order to minimize any mounting defects, the frame and the lenses must both be machined with rather high levels of precision as regards their dimensions and surface preparation.
  • the aim of the present invention is to provide eyeglasses which substantially eliminate the complications and risks that arise from installing the lenses on eyewires substantially constituted by metal wire shaped by plastic deformation.
  • an object of the present invention is to provide eyeglasses in which the previously treated lens can be installed even by personnel who is not particularly specialized.
  • Another object of the present invention is to provide eyeglasses which allow to achieve particularly appreciable aesthetic levels.
  • Another object of the present invention is to provide eyeglasses which can be manufactured with conventional technologies.
  • eyeglasses of the type which comprises a frame having a front which is at least partially provided by means of metal wire shaped by plastic deformation, said eyeglasses being characterized in that the metal wire that constitutes said front is shaped, at each eye region, so as to form a supporting eyewire for a corresponding lens which is open, before the insertion of said lens, at the articulated connection to the corresponding temple, with respect to the open portion of each one of said eyewires, the metal wire continuing so as to form a first end, which is associated with an articulation of a temple, and a second end, which is shaped so that it remains substantially parallel to the first end, locking means being provided which comprise at least one annular element which can be fitted by snap action and are suitable to keep said first and second ends packed together so as to provide reversible closure of the corresponding eyewire and lock the corresponding lens after it has been installed.
  • the metal wire that constitutes said front is shaped, at each eye region, so as to form a supporting eyewire for a corresponding lens which

  • figure 2 is a perspective view of the eyeglasses of figure 1
  • figure 3 is a partially sectional view of a detail of the eyeglasses of figure 1
  • figure 4 is a view of another detail of the eyeglasses of figure 1
  • figure 5 is another view of the detail of figure 4 during another step of assembly
  • figure 6 is a partial perspective view of a detail of a second embodiment of the eyeglasses according to the invention
  • figure 7 is a sectional view, taken along a transverse plane, of a detail of the eyeglasses of figure 6
  • figure 8 is a partial perspective view of a detail of a third embodiment of the eyeglasses according to the invention
  • figure 9 is a sectional view, taken along a transverse plane, of a detail of the eyeglasses of figure 8.
  • the eyeglasses according to the invention are generally designated by the reference numeral 10.
  • the eyeglasses 10 in this case comprise a frame which is generally designated by the reference numeral 11 and has a front 12 formed by metal wire shaped by plastic deformation.
  • the eyeglasses 10 comprise, again in this case, two temples 13 also made of shaped metal wire.
  • the metal wire that constitutes the front 12 is shaped, at each eye region, so as to form a corresponding eyewire 14 for supporting a corresponding lens 15; the eyewire is open, before the insertion of the lens, at an articulated connection, generally designated by the reference numeral 16, to the corresponding temple 13.
  • the lateral edge of the lens 15 is conveniently prepared by forming thereon a groove 17 which is shaped substantially complementarily to the metal wire that forms the corresponding eyewire 14 which fits inside it upon assembly.
  • each one of the eyewires 14 in this embodiment the metal wire continues so as to form a first end 18, which is associated with the corresponding articulated connection 16, and a second end 19, which is shaped so that it remains substantially parallel to the first end 18.
  • the eyeglasses 10 have locking means which in this case are constituted, for each one of the eyewires 14, by a corresponding annular element 20 which can be inserted on the first and second ends 18 and 19 when they are coupled.
  • Each one of the annular elements 20 is therefore suitable to keep the corresponding first and second ends 18 and 19 packed, thus also providing reversible closure of the corresponding eyewire 14.
  • Closure of the eyewire 14 locks the corresponding lens 15 after it has been installed.
  • the coupling stability of each one of the annular elements 20 is determined by a corresponding notch 21 formed in each one of the second ends 19.
  • each one of the annular elements 20 on the corresponding coupled first and second ends 18 and 19 occurs by slight interference and plastic deformation of the elastic rings 20.
  • a second embodiment of the eyeglasses according to the invention comprises a frame 111 which is partially illustrated in the above figures and is constituted by a front 112 which forms a half eyewire 114 for each eye region.
  • Each half eyewire 114 supports the corresponding lens 115 and is constituted by a metal element which is shaped by plastic deformation and forms in particular a free portion 116 located at the coupling 117.
  • the half eyewire 114 is characterized in this case by a substantially rectangular transverse cross-section, from which a raised portion 118 protrudes on the inner face for supporting the lens 115; the raised portion 118 is monolithic with the metal element that constitutes the half eyewire 114.
  • a groove 119 is formed correspondingly on the entire lateral edge of the lens 115 and is shaped complementarily to the raised portion 118 of the metal element.
  • Each coupling 117 is provided by the assembly of a first end and of a second end, respectively designated by the reference numerals 120 and 121 and made of metal wire, with the half eyewire 114.
  • the first end 120 is in fact associated, in a per se known manner, for example by welding, with a first end portion 122 of the half eyewire 114, at the free portion 116, whilst the second end 121 is associated with the second end portion 123 and is shaped so that it remains substantially parallel to the first end 120.
  • the coupling 117 is completed by an annular element 124 which can be fitted on said first and second ends 120 and 121 when coupled and is fully equivalent to the annular element 20 described earlier.
  • the first end 120 continues its extension by entering at an articulated connection, designated by the reference numeral 125, which constitutes the hinge of the eyeglasses.
  • the annular element 124 is fitted, and ensures the packing of the first end 120 with the second end 121, by taking care to place the annular element 124 in abutment within a complementarily shaped groove, not shown in the figures, formed on the second end 121.
  • a third embodiment of the eyeglasses according to the present invention comprises a frame 211 of which these figures illustrate a detail; the frame is constituted by a front 212 which is fully equivalent to the previous frame 111.
  • Each lens 215 is supported by a half eyewire 214 which forms a free portion 216 in a manner which is fully similar to the half eyewire 114 already described.
  • Each half eyewire 214 is obtained in this case by means of a metal element which is shaped by plastic deformation and has a polygonal transverse cross-section which forms a recess 218 at the inner edge to be placed in contact with the lens 215.
  • Each lens 215 correspondingly has a lateral edge which is beveled so as to form a point 219 which is shaped complementarily to the recess 218 of the half eyewire 214.
  • each coupling 217 is provided, as described above for the coupling 117, through the assembly of an annular element 224 which is inserted in a first end 220 made of metal wire and coupled to a second end 221 also made of metal wire; both are associated, in a per se known manner, for example by welding, with the half eyewire 214 at the free portion 216.
  • the possibility to have the eyewire open during assembly allows easy assembly of the corresponding lens without having to perform elastic or elastic-plastic deformations of the frame.
  • Assembly of the eyeglasses according to the invention is then completed very simply by snap insertion of the corresponding annular elements, in an operation which can be performed even by personnel who is not particularly specialized.

Abstract

L'invention concerne des lunettes comportant une monture présentant une face (12) pourvue au moins en partie d'un fil métallique façonné par déformation plastique. Le fil métallique constituant la face est façonné, dans la zone correspondant à chaque oeil, de manière à former un cercle (14) de support pour le verre (15) correspondant; ce cercle de support est ouvert avant l'insertion des verres, au niveau d'une charnière (16) articulée avec la branche (13) correspondante. Le fil métallique continue dans la partie ouverte de chaque cercle, de manière à former une première extrémité (18), subordonnée à l'articulation (16) de la branche (13), et une deuxième extrémité (19) façonnée de manière à rester sensiblement parallèle à la première extrémité (18). Les lunettes comprennent un dispositif de blocage constitué d'au moins un élément (20) annulaire pouvant être ajusté par encliquetage de façon à garder la première et la deuxième extrémité (18, 19) serrées l'une contre l'autre, formant ainsi une fermeture réversible du cercle (14) correspondant et bloquant le verre (15) correspondant après sa mise en place.
