US Patent 6908194 Eyeglasses with interchangeable and adjustable headband

An eyeglasses system comprises an eyeglasses frame having a pair of opposite temple regions an attachment interface at each temple region, and two or more sets of laces. The lace sets are interchangeably attachable and detachable from the attachment interfaces at the temple regions of the frame, such that laces of different styles may be used with the single frame. There are in some systems plural frames each having a pair of opposite temple regions with an attachment interface at each temple region, such that plural sets of laces may be freely interchanged and worn with plural sets of laces. Individual ones of the lace sets may include laces of one or more of different styles, colors, indicia, widths, or materials.
