  • Guiding washer for a hinge of an eyeglass frame
    Patent number: 6623115
    Abstract: A guiding washer is provided to a spring hinge of eyeglasses. The guiding washer is disposed between a male part and a female part of the spring hinge, which are made of titanium alloy, in such a manner that the washers can't pivot on the female part, and the male part can pivot on the washers. The washers are intended to reduce friction of the hinge's parts against each other when the male part is being pivoted on the female part, thus effectively increasing the smoothness of pivotal movement of the male part when in use.
