Publication number: 20240201516Abstract: A spectacle rod is provided, including a plate-shaped metal rod and a friction element located at an ear bend. In order to avoid inadvertent removal of the friction element from the metal rod, a protrusion and the recess are formed. The protrusion and recess include a first transverse protrusion at the outermost second end of the spectacle rod. This transverse protrusion, together with the spectacle rod, forms an outwardly open recess. This recess has a smaller cross-section at the opening than at a central part. Thereby, elastic compliant material from the friction element will be received in the recess. The elastic material will be compressed so that a clamping effect occurs, contributing to a retention which prevents accidental separation of the friction element and the metal rod.Type: ApplicationFiled: May 3, 2022Publication date: June 20, 2024Inventors: Henrik Lindberg, Lars Bøjvad, Hans Boye-Nielsen, Thomas Mach, Christian Bak Andersen

Publication number: 20230096733Abstract: 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.Type: ApplicationFiled: February 26, 2021Publication date: March 30, 2023Inventors: Jeppe Birch KOFOED, Henrik LINDBERG, Lars BØJVAD, Thomas MACH, Hans BOYE-NIELSEN

Patent number: 11143883Abstract: 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.Type: GrantFiled: September 12, 2017Date of Patent: October 12, 2021Assignee: Lindberg A/SInventors: Henrik Lindberg, Hans Boye-Nielsen, Thomas Mach, Lars Bøjvad, Ulrik Caspersen

Patent number: 7320516Abstract: 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.Type: GrantFiled: March 5, 2004Date of Patent: January 22, 2008Assignee: Lindberg A/SInventors: Flemming Kroman, Lars Bøjvad Jensen

Patent number: 6276796Abstract: An eyeglass frame comprising a frame front (15) with front end pieces (11) for the attachment of temple bars and with a pair of straps (7), each strap being formed in the shape of a loop adapted for peripheral engagement with a respective glass with respective strap member ends in generally abutting relationship, and provided with closure means (16,17) for interconnecting the respective strap. A pair of resilient members, each one adapted for resiliently tensioning a respective strap around the glass. Each closure means comprises a first and a second hook member, formed integrally with respective strap ends, and adapted so as to retain a mutual engagement.Type: GrantFiled: April 3, 2000Date of Patent: August 21, 2001Assignee: Lindberg A/SInventors: Poul-Jørn Lindberg, Lars Bojvad Jensen

Patent number: 6260965Abstract: 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.Type: GrantFiled: April 3, 2000Date of Patent: July 17, 2001Assignee: Lindberg A/SInventors: Flemming Kroman, Lars Bøjvad Jensen
