Abstract
Lenses are removably mounted on the brow bar of an eyeglass frame. A coupling part is fixed to the top of each lens, preferably by a rim member attached to the lens by conventional techniques. The coupling part is composed of magnetically attractive material and includes a protrusion. Each side of the brow bar carries one or more magnets to engage a coupling part and a recess to receive a protrusion to insure proper positioning of the lens relative to the brow bar. The coupling part may be retained behind, on top of, below or in front of the brow bar.
Claims22
Apparatus for removably mounting a lens to an eyeglass frame having a brow bar, said apparatus comprising a part affixed to the lens, said part comprising a first substantially flat surface section, first positioning means and first magnetic coupling means, said brow bar comprising a second substantially flat surface section, second positioning means and second magnetic coupling means, said first and second positioning means cooperating such that said first and second surface sections align and said first and second magnetic coupling means engage to mount the lens on the frame, wherein said first positioning means comprises a protrusion and said second positioning means comprises protrusion receiving means.
Apparatus for removably mounting a lens to an eyeglass frame having a brow bar, said apparatus comprising a part affixed to the lens, said part comprising first positioning means and first magnetic coupling means, said brow bar comprising second positioning means and second magnetic coupling means, said second positioning means being spaced from said second magnetic coupling means along said brow bar, said first and second positioning means cooperating such that said first and second magnetic coupling means engage to mount the lens on the frame, wherein said first positioning means comprises a protrusion and said second positioning means comprises protrusion receiving means.
Apparatus for removably mounting a lens to an eyeglass frame having a brow bar, the lens having a surface, said apparatus comprising a part affixed to the lens, said part comprising a member extending in a direction substantially parallel to the lens surface, said member comprising first positioning means and first magnetic coupling means, said brow bar comprising second positioning means and second magnetic coupling means, said first and second positioning means cooperating such that said first and second magnetic coupling means engage to mount the lens on the frame, wherein said first positioning means comprises a protrusion and said second positioning means comprises a protrusion receiving recess.
Apparatus for removably mounting a lens to an eyeglass frame having a brow bar, said apparatus comprising a part affixed to the lens, said part comprising a member extending over the lens and beyond the plane of the lens, said apparatus comprising first positioning means extending downwardly from said member and first magnetic coupling means, said brow bar comprising second positioning means extending upwardly and second magnetic coupling means, said first and second positioning means cooperating such that said first and second magnetic coupling means engage to mount the lens on the frame, wherein said first positioning means comprises a protrusion and said second positioning means comprises a protrusion receiving recess.
