Abstract:
1. A method of manufacturing spectacle frames using a celluloid plate, the method comprising: cutting the celluloid plate to process a front of the spectacle frames in which a hinge part is protrusion-formed at a side surface portion of the front, and forming a lens mounting groove in an inner circumference surface of an eyeball part of the front; forming two punch holes that pass through a front surface and rear surface of the hinge part to be inclined at a certain angle, for connecting temples to the hinge part that is protrusion-formed at a side surface of the front; forming a slot in a vertical direction orthogonal to an insertion direction of rivets, into which each of the temples is inserted, in a side surface portion of the hinge part with the punch holes formed therein; forming each temple that comprises a curved shaped connection part that is configured with a metal plate corresponding to a width of the slot, and an ear hanging part that is hinge-coupled to one end of the curved shaped connection part to be foldable in an internal direction, a through hole being formed in the other end of the curved shaped connection part; and inserting the one end of the curved shaped connection part into the slot
