Abstract: A pair of folding glasses includes a frame including two fronts, a bridge pivotably located between the two fronts, and two temples pivotably connected to the two fronts. Each front includes a connection portion which has a first notch defined in the top thereof. The bridge includes two recesses which are respectively engaged with the first notch of the two connection portions. Two wings extend form the two ends of the bridge and each wing include a hole. Two positioning units pivotably position the two wings to the two connection portions. Two positioning units connect the bridge to the two connection portions. Two arms are retractably inserted into the two temples via two respective openings in one end of each temple. The two fronts are pivotable about the two positioning units. The two temples are pivotable relative to the fronts.

Abstract: A pair of eyeglasses includes a front with two lenses installed in the two openings thereof. Two lugs respectively extend from two ends of the front and each have a slot communicating with the opening corresponding thereto. Two threaded holes are respectively defined through the two ends of the front and communicate with the two slots. Two screws threadedly extend through the two threaded holes to narrow the slots to secure the two lenses in the front. The two lugs are clamped between the two connectors and two securing members by bolts extending through the securing members, the lugs and the two connectors, and connected with two positioning members. The lenses can be replaced by unscrewing the bolts and the screws.

Abstract: A flip-up eyeglasses include a main eyeglass, a secondary eyeglass, and an elastic hook member. The main eyeglass has a main frame, and the bridge of the main frame is connected with a connecting member extending horizontally forward. The connecting member has two engaging slots and two rectangular-shaped positioning portions that are formed between the front edge of the connecting member and the two engaging slots. The secondary eyeglass has a secondary frame, and the bridge of the secondary frame forms two grooves. The elastic hook member has a sheet portion and two hook portions that are configured to be hooked onto the two positioning portions through the two engaging slots and to be abutted against the two grooves, such that the positioning portions are sandwiched by the bridge of the secondary frame and the hook portions of the elastic hook member.

Abstract: The present disclosure pertains to a book jacket which can accommodate eyeglasses and a book. The book jacket includes a book jacket main body and pockets disposed respectively at two ends of the book jacket main body. An inner layer is disposed at the inner surface of the book jacket main body. When the book jacket is folded, the folding inner layer spine portion and the folding book jacket spine portion define an accommodating space therebetween. The book jacket spine portion has a slit, and a storage pull tab, one end of which is fixed to the inner layer spine portion, and the other end of which passes through the slit of the book jacket spine portion and extends outward. The inner layer spine portion has a bookmark. The present disclosure cleverly forms an accommodating space for storing eyeglasses in the book jacket.

Abstract: An eyeglass frame which can be suspended on a neck and rotatingly folded includes a rim structure, two temples and two connection units. The rim structure are respectively connected by the two connection units to the two temples. A teeth structure is integrally formed perpendicularly on each of the abovementioned ends of the rim structure. The lower end of each of the connection units is formed with a flange structure for engaging with a teeth structure. The upper end of each of the connection units is connected by hinge to a temple front portion. Each of the temples includes an outer temple and an inner temple respectively slidably embedded in the outer temple. The rear portions of the temples have magnets which mutually attract to form a loop structure. The rim structure can rotate upward to adapt to the contour of the face, and is thinner when folded.

Abstract: An eyeglass frame having flexible pivot hinge enabling approximately 180° bending. The frame includes a frame, a temple and a hinge. The frame has a tenon receiving hole and a frame screw hole perpendicular thereto. The temple has a stem receiving hole and a temple screw hole perpendicular thereto. The hinge has a frame joint and a temple joint. The frame joint has a pin seat formed with a bore and a tenon formed with a tenon screw hole. The temple joint has a stem formed with a stem screw hole and ending with substantially U-shaped fork. A channel passes through the two branches of the fork. The instant disclosure includes relatively minimum members for easier maintenance and increased comfortableness.

Abstract: A detachable eyeglass frame includes a lens frame, a pair of hollow temples, a pair of temple inserts and a pair of hinges. The temple insert resembles a stick ending with a blade having a pocket for receiving the asymmetrical V-shaped hinge. The hinge has a column at one tip and a screw receiving column at the other. The temple insert is received by a sleeve formed within the temple and furthermore the hinge is inserted to the pocket of the temple insert for connecting the temple to the lens frame through a screw.
