Abstract
Eyewear has a wire that encircles each of a pair of lenses respectively. A tensioning assembly can adjust and tension the wire. Two variations of tensioning assemblies are shown. One tensioning assembly has a spool on which a portion of the wire is wound. Another tensioning assembly has an insert that pulls a portion of the wire inwardly within a projection that extends outward from the lens.
Claims39
Eyewear comprising a first lens and a second lens, a first wire substantially encircling said first lens and a second wire substantially encircling said second lens, a first end and a second end of said first wire being connected to a first insert, a first end and a second end of said second wire being connected to a second insert, a first sleeve receiving at least a portion of said first insert, a second sleeve receiving at least a portion of said second insert, a first threaded fastener extending through a portion of said first sleeve and engaging a portion of said first insert such that tightening said first threaded fastener increases a tensile load on said first wire, a second threaded fastener extending through a portion of said second sleeve and engaging a portion of said second insert such that tightening said second threaded fastener increases a tensile load on said second wire.
Eyewear comprising a first lens and a second lens, a first wire substantially encircling said first lens, a first projection being connected to a first end of said first wire, said first projection comprising a first bore and a first passage extending to said bore, a second end of said first wire extending through said first passage, and a first spool being connected to said second end of said first wire and being positioned within said first bore.
Eyewear comprising a first lens and a second lens, said first lens comprising a first peripheral side surface and said second lens comprising a second peripheral side surface, a first projection extending away from said first peripheral side surface and a second projection extending away from said second peripheral side surface, a first wire end and a second wire end extending through a portion of said first projection, a third wire end and a fourth wire end extending through a portion of said second projection, a first threaded member being positioned within said first projection and being adapted to move at least a portion of at least one of said first and second wire ends in an axial direction through said portion of said first projection, and a second threaded member being positioned within said second projection and being adapted to move at least a portion of one of said third and said fourth wire ends in an axial through said portion of said second projection.
Eyewear comprising a lens, said lens comprising a peripheral side surface, a projection extending away from said peripheral side surface, a first wire end and a second wire end being connected to said projection, a spool member being positioned within said first projection, at least one of said first wire end and said second wire end being connected to said spool member such that rotation of said spool member wraps a portion of said at least one of said first wire end and said second wire end about at least a portion of said spool member.
