ABSTRACT:
A spectacle frame includes two extensions extended from the side portions and each having a pivot shaft and a channel. A pair of legs each has one end engaged through the channels and secured to the pivot shaft so as to allow the legs to be rotated about the pivot shafts. The legs each has a slide slidably engaged on the end end and each has a spring for biasing the slides to engage with the extensions. The springs may be easily engaged on the legs. No holes or cavities are required to be formed in the legs such that the strength of the legs will not be decreased.
