This invention relates to a spring-biased hinge assembly for spectacles. The hinge assembly comprises a bow-side section defining a cavity, and a slider, which carries a bow-side hinge element and extends into the cavity and is adapted to be extended from said cavity against spring action. The bow-side hinge element cooperates with the midportion-side hinge element. The hinge assembly should be slender and should be accommodated to a large extent in the end portion of the bow. For this purpose, the cavity is defined by a flat tubular element, in which a tongue of the slider is slidably mounted. The tongue has a longitudinal slot, in which the return spring extends, which engages an abutment that extends into the wall of the tubular member and through said slot. |
