The invention relates to a central part for an eyeglass hinge, comprising: a first articulation region, which is designed to connect, with articulation about a first articulation axis, the central part to a frame of eyeglasses; a second articulation region, which is designed to connect, with articulation about a second articulation axis, the central part to a temple of the eyeglasses; and a cable guide opening, which extends through the central part perpendicularly to the articulation axes and is designed for the feeding of a cable from the temple to the frame through the central part, the cable guide opening being open in the direction of the articulation axes at least on one side.

A multiple degree of freedom hinge system is provided, which is particularly well adapted for eyewear, such as spatial computing headsets. In the context of such spatial computing headsets having an optics assembly supported by opposing temple arms, the hinge system provides protection against over-extension of the temple arms or extreme deflections that may otherwise arise from undesirable torsional loading of the temple arms. The hinge systems also allow the temple arms to splay outwardly to enable proper fit and enhanced user comfort.

A adjustment sound-generating temple includes a hinge member, a connecting seat and a temple. The hinge member has a saw teeth and a pivot pins on one surface, the connecting seat is provided with an insert slot on one end and an extension rod on the other, which has two saw teeth on each of its inner side. The temple is assembled by combining the hinge member and the connecting seat. The completed temple is then connected to the frame, forming a spectacle that makes clicking sounds when adjusting the temple's angle. The clicking sounds help to enhance the quality of the spectacle as a whole.

Eyeglasses are provided capable of folding into a substantially flat configuration that may be fitted inside a compact case or other narrow space. The eyeglasses may include a frame configured to hold one or more lenses and defining an imaginary plane, at least one temple piece, and at least one hinge connecting the at least one temple piece to the frame, wherein the hinge is configured to rotate the at least one temple piece between a first position extending substantially perpendicular to the imaginary plane defined by the frame, and second position extending substantially parallel to the imaginary plane.

Eyeglass frames that are both adjustable fore and aft on each side, and that allow each lens to be raised or lowered slightly so that the glasses fit well with both lenses at the same vertical level. Embodiments of the present invention includes a small ratchet and hinge on each arm that allows the forward part of the frame to rotate slightly up or down. In addition, in other embodiments, both legs can have a sliding length adjustment that allows the leg to fit snugly behind the ear on each side with the lens in the correct fore and aft position. Some embodiments of the present invention have both features present, while other embodiments have only one or the other feature.

A spectacle frame includes a front face and temples connected thereto by hinges. Each hinge includes a hollow attachment member, respectively rigidly connected to the front face and to the temples, and each receives a hinging member having its free end provided with a hinge pin, such that the hinge pins are perpendicular to each other. The attachment members define a cylindrical sheath. The hinging members each include a rod, intended to be received in the respective sheath, one of the ends of the rod being provided with an abutment and the other end being provided with the hinge pin, each of the rods receiving a sliding ring submitted to the action of a spring bearing against the abutment, the ring being rigidly connected to the corresponding attachment member near its free end. The hinge pins of the hinging members are rigidly connected to each other by a connection member.

A slip-resistant eyewear system comprising an angular adjustment screw configured to couple to a first hinge of an eyewear frame such that an angle of the eyewear frame is adjustable relative to a first bow and a unitary eyewear retainer comprising a first end configured to couple to the first bow and a second end configured to couple to a second bow such that a tension is maintained on the unitary eyewear retainer when the unitary eyewear retainer extends around a back of a head of a user.

An eyeglass retainer system for use with eyeglasses worn by a user and having a frame front includes a pair of eyeglass temples. Each temple has a first end for securing the temple to frame front and defines a first channel passing therethrough that terminates in a first stopping mechanism. Extendable coupling units are slidably disposed in the first channels and terminate in a first stopper that is configured to engage the first stopping mechanism so as to prevent it from exiting the first channel completely. Two magnetic connectors are each affixed to a different one of the extendable coupling units and have opposite polarities so as to attract each other when placed against to each other. The coupling units are slid out of the first channel so that the two magnetic connectors can be coupled to each other behind the user's head so as to retain the eyeglasses.

The multiuse eyeglasses include a frame that holds two lenses and arms that extend from the frame. The arms include a first axis of rotation that is generally perpendicular to the arms and a second axis of rotation that is orthogonal to the first axis of rotation and allows the arms to be rotated downwards relative to the frame.

A temple assembly for a pair of spectacles, including a spectacle temple body, a guide member, a first temple core, a second temple core, a first pivot; and a second pivot; wherein the second temple core is elastically connected with the spectacle temple body, the guide member is sleeved onto the first temple core, two connecting end of the first temple core is respectively pivotally connected to the second temple core and a pile head of a rim, the first pivot and the second pivot are disposed perpendicular to each other. When the spectacle temples are subjected to loads in two different directions from a horizontal direction and a vertical direction, the spectacles temple cause to produce an elastic bend of different directions at a front end and a rear end of the guide member, the user experience that the temples can be rotated 360 degrees is better.
