Definitions

  • This invention relates to spectacle frames and is concerned with the provision of an interchangeable bridge for such frames.
  • Spectacle frames have a bridge portion extending between the rims ⁇ of the frame which carry the ' two lenses, the bridge portion being adapted to span the nose of the wearer and to support the frame on the nose of the wearer.
  • the bridge In order for a pair of spectacles to be comfortable for a given - ⁇ wearer, it is necessary for the bridge to be adapted to the nose of the wearer so as to be a good and comfortable fit.
  • the present invention provides an inter ⁇ changeable bridge for a pair of spectacles comprising a resilient bridge frame adapted to releasably clip into the bridge portion of the main frame of the spectacles, the resilient bridge frame being covered with a shaped body to form the- bridge f of the spectacles.
  • the bridge frame is in the form of an open inverted "U” shape having a lug formed at the end of each arm, said lugs being_arranged to engage in respective recesses formed in the main frame of the spectacles.
  • the bridge frame is formed from spring wire which is preferably chrome or-gold plated .
  • the shaped body is formed of a silicone rubber or a synthetic plastics material. Such ⁇ aceriai will take up Hit- irregular contour of a wearers nose an also has non-slip properties.
  • the invention also extends to an assembly of a main spectacle frame and such an interchangeable bridge.
