ABSTRACT:
This invention relates to a bow and spring hinge assembly for eyeglasses, in which each bow can be opened beyond a stop-defined position so that the bow can resiliently bear on the head of the wearer. The novel assembly can be used also with slender and thin bows and provides for a transverse bracing for eliminating a transverse backlash between relatively slidable parts. For this reason the assembly is provided in the slider and in the bow end portion with recesses, which face each other and each of which is provided on opposite sides with inwardly facing track grooves, and I-section members are provided, each of which is in sliding contact with the track grooves of both said recesses so that said I-section members hold said bow end portion and said slider together against a transverse separation.
