Abstract: A temple adjustment mechanism includes a male side member joined to one side of a lens frame, and a female side member relatively movable to and from the male side member. A temple is hingedly connected to the female side member. The male and female side members are relatively movable between a retracted position and an extended position. A spring is connected between the male and female side members to hold the two side members in their retracted position. A linkage extends between the male and female side members and is manually operable to move the two side members to their extended position from their retracted position. When the male and female side members are moved to their extended position, the female side member is longitudinally spaced from the male side member so that the overall length of the temple is increased.

Abstract: A hinge system for eyewear includes a pivotable hinge element for connecting a temple to a lug on each end of a lens frame. The pivotable hinge element has one end pivotably connected to the lug and the other end arranged to allow the temple to be pivotably moved between a wearing position and a folded position. First and second magnets are provided in the lug and the pivotable hinge element, respectively. The first and second magnets have respective confronting surfaces oriented to face against each other when the temple is in its wearing position. The confronting surfaces of the first and second magnets have an identical polarity, so that the first and second magnets are operatively associated to urge the temple inwardly toward its folded position when the temple is moved to its wearing position.

The male section includes a male body, a projection extending from one end of the male body and including a transverse bore, and a locking element movable between an unlocked position wherein the locking element is received within the bore and a locked position wherein the locking element is partly extracted from the bore. A first magnet is embedded in the locking element. The female section includes a female body having a guide cavity dimensioned to receive the projection, and a transverse locking recess dimensioned to lockingly receive a part of the locking element as extracted. A second magnet is embedded in the female body adjacent to the locking recess.

Abstract: A nose pad assembly is slidably mounted to an eyeglass frame by which a pair of multifocal lenses are held. The nose pad assembly includes a pair of oval nose pads within which elongated guide grooves are defined. Two pairs of upper and lower magnets are coaxially and fixedly mounted in the upper and lower ends of the respective nose pads. A pair of slides are slidably moved along the guide grooves and attached to a pair of pad arms of the eyeglass frame. The slides include a corresponding pair of slide magnets positioned within the respective guide grooves. The slide magnets are selectively attracted to the upper and lower magnets to hold the eyeglass frame in its upper and lower positions, respectively. A bridge member extends between the upper end of the nose pads. The bridge member is configured to resist a substantially vertical force which may be applied thereto when the eyeglass frame is moved between its upper and lower positions.

Abstract: An adjustable eyeglass frame includes a lens frame assembly adapted to hold a pair of lenses, and a nosepiece assembly including a pad mount attached to the lens frame assembly. The nose piece assembly has a pair of legs connected to the pad mount, a pair of nose pads carried by the legs and pivotably movable toward and away from each other, and a bias mechanism for biasing the nose pads toward each other so that the nose pads are safely held in any selected vertical positions.

Abstract: An eyeglass frame includes a pair of rims in which a corresponding pair of bifocal lenses are mounted, and a pair of temples connected to the respective rims. Each of the temples includes a joint secured to a corresponding one of the rims, a leg having one end connected to the joint and the other end resting behind a wearer's ear, and a mechanism for enabling pivotal movement between the joint and the leg in a vertical plane so as to permit movement of the bifocal lenses between a normal position and an elevated or reading position. The mechanism is so constructed as to decrease the distance between a first point at which the joint is connected to the rim and a second point at which the joint is connected to the leg when the lenses are moved from their normal to elevated position.

Abstract: An ophthalmic mounting for bifocal lenses includes a pair of rims on which a pair of right and left bifocal lenses are mounted. The rims are symmetrically arranged with respect to a vertical axis. The ophthalmic mounting includes a pair of pad arms connected to the rims, and a pair of nose pads detachably secured to the pad arms and oriented to diverge downwardly from the vertical axis. The nose pads includes a pair of generally flat bodies, a pair of guides integrally formed in the bodies and having a pair of elongated guide recesses, and a pair of slides. The slides have a pair of sliding portions slidably received within the respective guide recesses, and a pair of mounting portions connected to the respective sliding portions and detachably secured to the pad arms. The guide recesses lie on two substantially parallel imaginary vertical planes, respectively so as to enable the slides to be smoothly moved along the guide recesses.

Abstract: An ophthalmic mounting includes a pair of pad supporting arms connected to an eyeglass frame, and a pair of hollow nose pads including a pair of elongated guide openings, and a pair of sliding members carried by the pad supporting arms and freely slid along the guide openings such that at least two different focal fields can be moved into and out of desired position of use. A pair of movable magnets are attached to the sliding members. A pair of fixed magnets are attached to the upper ends of the nose pads and adapted to cooperate with the movable magnets so as to lock the eyeglass frame or lenses in a raised position. Another pair of fixed magnets are attached to the lower ends of the nose pads and adapted to cooperate with the movable magnets so as to lock the eyeglass frame or lenses in a lowered position.

Abstract: The inner sides of left and right lens rims constituting the main body of a frame for multifocal spectacles are provided with respective guide portions extending downwardly from a bridge connecting the rims together. Left and right nose-pads of a nose-pad member are secured in the guide portions under tension using left and right resilient pieces configured to gradually curve away from each other. This makes it possible to move the nose-pads up and down smoothly and reliably.

Abstract: A frame for multifocal spectacles includes a side piece attached to each of a pair of lens rims through a hinge mechanism which permits downward rotation of the side piece relative to the rim through a prescribed angle. A nosepad is mounted on each of the lens rims through a level adjusting mechanism by which the nosepad is vertically moved causing the level of the lens rims to be altered in correspondence to the change of inclination of the side piece.By means of the hinge mechanism, through a simple operation, each lens segment of the multifocal lens can be used at the optimum angle with respect to the line of vision, and by means of the level adjusting mechanism for moving the nosepad vertically, each lens segment is moved vertically to the level most suitable relative to the line of vision. At the same time neatness of appearance and decrease of eye fatigue result, whichever pair of lens segments is used.
