Abstract: Angle adjustment arrangements for eyeglass temples are provided in which each arrangement comprises an end-piece of frame including a recess and an opening; a connection mechanism received in the recess and including first and second circularly shaped bifurcated ends and a first series of serrations on an inner wall of first circularly shaped bifurcated end; and a fastening mechanism received in the opening and including a second series of serrations formed on an inner shank; and a temple secured to the connection mechanism wherein a ridge of second series of serrations is interfitted into a space between adjacent ones of first series of serrations for pivotably securing connection and fastening mechanisms together, thereby allowing temple to be pivoted with respect to end-piece in an operating state.

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.

Abstract: A safety goggles comprises a frame including an attachment member projected above the top center and a slanted coupling surface on the top of the attachment member; a lens fitted in the frame; a protector guide; a shade including a frame, an opening defined by the frame, a flange extended inward from the frame, studs on the frame of the shade, projections on either inner side of the flange of the shade, an engagement member projected above the top center of the flange of the shade, and an inclined coupling surface on the top of the engagement member; a protector lens including holes on the periphery being snugly engaged with the studs when the protector lens is fitted into the shade; a dark lens abutted on the protector lens; and an abutment member including alternate risers on the front peripheral edge, the abutment member being abutted on the dark lens within the shade such that the projections is capable of securing the abutment member to the dark lens.

Abstract: An eyeglasses temple angle adjusting device includes an angle adjusting member connected between an end of a frame and an inner end of a temple. The angle adjusting member is provided with two second vertical concave toothed sections and each end of the frame is provided with two ears formed divided by an intermediate opening. The two ears are provided with first two convex toothed sections to engage the second two concave toothed sections. The angle adjusting member further has an engage member at a side to fit in an engage hole formed in a wall defining the intermediate opening, and a front horizontal movable section to fit movably in the intermediate opening so that the angle adjusting member may be moved up and down by engagement of the first and the second toothed sections, permitting the temple to move up and down in its angle to the frame.
