Abstract: A hinge is provided for pivotally connecting a temple bar and the rims of eyeglass frame including: a first part with an upper flange where a first aperture provides a tight fit for a locking pin head section, and a lower flange provided with a recess for receiving the locking pin cylindrical body, a second part with a second aperture having a higher surface roughness than the locking pin cylindrical body, thereby having a higher surface friction between the bushing and the aperture than between bushing and the locking pin—a bushing with an inner opening, a locking pin having a head section and a cylindrical body The second part arranged with a bushing is inserted between the upper flange and the lower flange of the first part. The locking pin is inserted through the first aperture through the inner opening of the bushing and received in the recess.

Abstract: Self-locking eyeglass system, comprising at least one locking element and at least one frame element, wherein the frame element additionally comprises a connection element, which is intended for connecting with a locking element, and wherein the frame element is non-interrupted in its external circumference, and wherein the connection element is provided on the inner side, wherein the self-locking eyeglass system additionally comprises two hinge elements, which each comprises an adapter element, which matches a recess in the frame element, wherein each hinge element has a connection element, which coincides with the frame element's connection element, when the hinge elements are mounted in the at least one frame element's recess, and wherein each hinge element is secured to the at least one frame element by a locking element, whereby a convenient, flexible and uncomplicated way to assemble, separate, replace and service a self-locking eyeglass system is achieved.

Abstract: Spectacles with interchangeable eyeglass lenses (2), where the spectacles comprise a spectacles frame (1) and eyeglass lenses (2), where the eyeglass lenses comprise a mount (3) which is secured to an outer edge of the eyeglass lenses, and where at least one of the mount and the spectacles frame comprises a coupling element (8), which can couple together the mount (3) and the spectacles frame (1), thereby producing a spectacles frame in which the eyeglass lenses can be replaced as desired. Furthermore, the mount or the spectacles frame comprises an oblong recess (5) designed to receive a partial section (7) of the spectacles frame or a bulge on the mount. Said spectacles are suitable for use at work, bicycling in blustery weather, or skiing in harsh sunlight.

Abstract: There is described an apparatus and a fixture used in determining position and for producing assembling holes in a spectacle lens for rimless spectacles. The assembling holes are intended for receiving a U-shaped bracket which is used in fastening bridge and side bar hinge. The apparatus and fixture includes interacting guide pins and guide holes. These guide holes/pins are unambiguously disposed. The guide holes will preferably be placed symmetrically in relation to a hole center line for the lens, when this is placed in the fixation opening of the fixture with the hole center line disposed opposite to markings at the fixation opening. The assembling holes are thus placed symmetrically in relation to the marking. By such a system it is possible to make rimless spectacles that appear very accurate, without special skilled qualifications on the part of the optician to make assembling holes in the lenses.

Abstract: An eyeglass frame comprising a frame front, a pair of temple bars and respective hinge means, adapted to provide a pivotal connection of each temple bar with the frame front. According to the invention each hinge means comprises a cooperating pair of friction members (13,15) and a spring means (13) adapted for applying balanced, radially directed biasing forces onto the cooperating pair of frictions members. Hereby any play in the hinge is eliminated and the friction is maintained. Further the invention provides an eyeglass and a method of manufacturing an eyeglass.
