Eyeglasses with simplified hinge include a pair of lenses, a pair of temples and a hinge for connection between each one of the temples and the lenses. The hinge includes an element for connecting the lens and the temple, adapted to be connected to the lens at one end and provided, at an opposite end, with a portion adapted to engage a retention and locking element. The temple is provided with a cavity adapted to accommodate and lock the retention and locking element, the retention and locking element acting as a rotation fulcrum for the temple with respect to the connecting element.

A lens interchange mechanism for an eyewear may include a magnetic latch operatively associated with the eyewire of the eyewear, such that the a portion of the eyewire can be released, with a free end separating from another portion of the eyewire thereby forming a gap in the eyewire for the removal and installation of a lens. The magnetic latch mechanism may be further configured for easy re-latching by the application of opposing forces on the first and second eyewire portions to cause the free end to re-engage with the magnetic latch without manual actuation of the latch.

Aspects of the present invention relate to a head-worn computer, comprising a removable and replaceable adjustable nose bridge assembly, wherein the adjustable nose bridge assembly has at least three user adjustable features to adapt the adjustable nose bridge assembly to the user's nose, wherein a first adjustment of the at least three user adjustable features is adapted to move the adjustable nose bridge up and down relative to a lens of the head-worn computer, wherein a second adjustment of the at least three user adjustable features is adapted to rotate a nose pad of the adjustable nose bridge about an axis substantially perpendicular to a top frame of the head-worn computer, and wherein a third adjustment of the at least three user adjustable features is adapted to flare the nose pad to the side of the axis.

A spectacle mount is described, comprising a front frame (2) with lateral lugs (4) and respective rods (5), each rod-lug pair comprising a first and a second articulation element (6, 7) and an insert (12) constrained to the first articulation element (6), a recess (17) being defined in the insert (12) and intended to receive, at least partially, a head (11) of the second articulation element (7) during the movement relative to the first articulation element (6), a shoulder surface (22) defined on the insert (12) being able to contact the head (11) during the articulation movement, so that the second articulation element (7) is movable from and towards open and closed positions of the rod on the mount, in a guided and contacted manner between the insert (12) and the first articulation element (6), to achieve a hinge movement between the lug (4) and the rod (5).

Method for the assembly of elastic hinges on an eyeglass frame, wherein each elastic hinge has a first and a second articulation elements hinged around a hinging axis. The method provides for a first step of inserting the first articulation element in a first seat of a temple and, subsequently, a second step of inserting the second articulation element in a second seat of an end piece of the eyeglasses. In the first insertion step, the second articulation element is placed perpendicular to the first articulation element with the hinging axis placed at a first distance from the temple. Before the second insertion step, a tensioning step is provided in which the second articulation element is rotated up to being arranged parallel to the first articulation element, bringing the hinging axis to a second distance from the temple that is greater than the first distance.

Apparatus and systems related to modular eyeglass elements may be provided. A detachable temple may be detachably coupled to a lens assembly at a temple strut of the lens assembly via a locking mechanism. Locking mechanisms may include spring tab, spring lever, spring bar, snap-fit, spring latch, and other disclosed configurations.

The present invention relates to a novel screw that causes drag and prohibits unwinding of the screw. The screw is designed for use in eyeglasses for securing eyeglass lenses and prohibiting same from falling out. The screw includes a fillister head, a drive disposed on the head for engaging a screwdriver, a shaft running from the head to a terminal end, the shaft having non-contiguous circumferential threads along the length of the shaft for rotatably sliding the screw through slots. The screw includes a longitudinal channel in the form of a slot disposed along the surface of the shaft and through the length of the shaft. A planar bar of neoprene or any other polypropene can be inserted in the channel which assists with prohibiting unwinding of the screw when the screw is in use.

An eyeglass lens replacement assembly is revealed. A frame includes a lens insertion slot disposed on a lower edge and a mounting indentation communicating with the lens insertion slot. A bevel is formed on each of two sides of the front end of the mounting indentation. A movable mounting member is mounted in the mounting indentation and has two mounting pins and a concave part formed on a middle part of the mounting pin. The upper edge of a lens is inserted into the lens insertion slot while the lens includes a mounting slot corresponding to the mounting pins and two protruding portions corresponding to the concave parts of the mounting pins. The movable mounting member can turn back and remain positioned by the bevels of the mounting indentation combined with recovery elasticity of the two mounting pins of the movable mounting member. No additional elastic members are required.

Connection element for connecting two parts of eyeglasses, comprising a first body provided with a through hole, a second body provided with a threaded hole, and a connection screw inserted in the through hole and screwed in the threaded hole in order to fix together the two bodies. The through hole of the first body comprises an internal chamber made as an undercut and housing the head of the connection screw. The connection screw is movable between an alignment position, in which its head is aligned with the edge of the through hole of the first body in order to allow the passage of the head, and a misalignment position, in which the head of the connection screw and the edge of the through hole are angularly offset in order to prevent the head of the connection screw from exiting from the internal chamber of the through hole.

The invention relates to a pair of eyeglasses. The eyeglasses include a frame, a lens, and a movable tenon-like piece. The frame is provided with a mounting slot which is defined by a front wall, a rear wall, and a top wall of the frame and having an opening facing downward. An upper edge of the lens is mounted into the mounting slot. The movable tenon-like piece is inserted through the rear wall and the upper edge of the lens. When the movable tenon-like piece is moved horizontally from an unlocked-and-released position to a locked-and-fixed position, the lens with the upper edge mounted in the mounting slot of the frame is fixed in that state. The assembly of the frame with the lens is completed.
