Abstract:
An angle adjustment mechanism for an eyeglasses comprising:a connection device pivotably coupled to a frame of the eyeglasses and including an engagement member at a rear end, a cross-shaped aperture open to an outer side, a cavity open to an inner side and abutted on the cross-shaped aperture, an elongated protrusion extended horizontally from the engagement member, a recessed portion on the outer side, and a ridged section in the recessed portion; a temple including a connection section, a cut-out member in a front inner portion of the connection section, a hole through the cut-out member, a transverse rhombic aperture abutted on an inner end of the hole, a recess on a shoulder between the cut-out member and the connection section, and a peg projected horizontally from a front end of the cut-out member; and a snapping device including an outer disk-shaped head, a shank adapted to an engagement of the transverse rhombic aperture and the cross-shaped aperture, and an abutment member at one end passed through the transverse rhombic aperture and the cross-shaped aperture; wherein the engagement member is engaged with the cut-out member with the elongated protrusion received in the recess to cause the cross-shaped aperture to be open to the transverse rhombic aperture, the snapping device is inserted into the hole from the outer side of the connection section to pass the abutment member through the transverse rhombic aperture and the cross-shaped aperture to be flush with the cavity, the abutment member is rotated about 90 degrees to urge the abutment member against the cross-shaped aperture, and the peg is slidably engaged with the ridged section so that it is operable to rotate the temple clockwise or counterclockwise a predetermined angle to slide the peg along the ridged section until the peg is positioned between a valley between two ridges of the ridged section.
