Definitions

  • the present invention relates to an eyewear assembly and to a method for obtaining the same. More particularly, the preferred embodiments of the present invention relate to an eyewear assembly having a base frame with removably engageable frame attachments
  • Known spectacle frames are generally comprised of metal or plastic frame members commonly comprising a frame front and two temples.
  • the frame front is typically comprised of two oval-shaped lens sockets connected together by a bridge.
  • the lens sockets are adapted to receive either plastic or glass lenses.
  • the lenses are usually placed in the lens sockets and permanently affixed in the frame front by fastening screws in the frame front.
  • the plastic can be heated so that the frame expands and the lenses are inserted in the lens sockets. As the plastic cools and contracts, the lenses are fixed in the lens sockets.
  • one disadvantage of such spectacle frames is that the lenses are either permanently connected to the frame front or can only be removed with special tools and/or by using significant effort.
  • Another disadvantage is that the appearance of the spectacle frames cannot be changed easily.
  • US 5 631 71 6 in the name of Chao relates to a pair of goggles including replaceable prescription lenses.
  • the lenses are kept in position by a flexible gasket, which is in turn engaged into the body of the goggles.
  • a first method consists in first inserting the lens into the gasket and then inserting the gasket into the goggles; this method has the disadvantage that the lens could come out from the gasket during the insertion.
  • the second method consists in first inserting the gasket into the goggles and then inserting the lens into the gasket; this method has the disadvantage that the gasket could come out of the goggles during the insertion. Besides, the removal of a lens also presents the above discussed disadvantages.
