Abstract

An angle adjustment mechanism for a temple of eyeglasses comprises a square recess at an endpiece of a rim, a hole through the square recess, an abutment member including a square member shaped to conform to the square recess, an annular projection on the square member, a first annular toothed portion spaced from the square member by the annular projection, and a plurality of slits across the first annular toothed portion for providing a flexibility when the first annular toothed portion is compressed, a pivot member pivotably secured to the temple, the pivot member including an annular recess and a second annular toothed portion on the bore of an aperture therethrough, and an engagement member including a plurality of protrusions with latched ends, any two adjacent protrusions being separated by a gap. The protrusions are inserted through the pivot member, the abutment member, the square recess, and the hole for pivotably securing them together wherein the annular recess is engaged with the annular projection and the second annular toothed portion is meshed with the first annular toothed portion.
