Abstract
An eyeglass frame having first and second rims for receiving lenses, temple pieces for positioning the frame over the user's eyes, and a first resilient bridge. The first bridge is coupled between rims and has first and second cables for allowing the rims to pivot about the first bridge between an original position and displaced positions while biasing the rims toward the original position. Each of the cables is rigidly coupled between the rims and formed by multiple strands that are spirally-wrapped around each other. The cables are adjacent one other and spirally-wrapped in opposite directions. The first bridge can include a rotating bar for added stability. The eyeglass frame can also have a second bridge formed of a flexible bar or of at least one cable that has multiple strands that are spirally-wrapped. The second bridge can be a single cable with or without a protective cover, or multiple cables that are spring-biased towards each other. The second bridge configurations can be used with any of the first bridge configurations.
