A wearable head-up display which allows for convenient and safe stowage when not in use. A hinge component is positioned within the optical path from an image projector to a display component which ensures optical alignment for projection. A detection means is provided to signal when the wearable device is in a folded position in order to deactivate the projector.

A wearable lightweight, adjustable, and comfortable modular eyewear with multiple interchangeable components includes: a central frame with two eyeglass supporting members, lenses, temple and hinge. The assembly has a hinge which is designed to fit the frames. The fronts and temples are grooved to allow the hinge to fit snuggly into the grooves. The hinge is flexible that it will allow the temples to flex 180+ degrees.

A spectacle frame including a first part, at least a second part, a joining part joining the second part to the first part allowing to fold and unfold the second part relative to the first part so that the second part be movable between respective closed position and open position, at least an electrical wiring arranged through the joining part to allow an electrical connectivity between the first part and the second part, wherein the joining part is elastically deformable with curvature radius values higher than a predefined minimum curvature radius value.

Disclosed is a 3D printed eyewear frame having an integrated hinge. Advantageously, the integrated hinge assembly is a crossed spring hinge. Methods of manufacturing a 3D printed eyewear frame are likewise provided.

This patent application relates to spectacles or spectacle frames with intertwining helix joints and a nose pad portion to facilitate an interchanging of lenses of the spectacles. The helix joint allows the temples to move into a folded position. The nose pad portion provides an access portion for detaching and/or attaching the lenses.

3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

There is disclosed a wearable item. The wearable item includes at least one elongate member for supporting at least one attachable element. The elongate member is fabricated from an inner core that is surrounded by at least one outer layer. The at least one outer layer is elastic when strained by application of stress below a first elastic limit. The inner core is elastic when strained by application of stress below a second elastic limit or permanently deformed when strained by application of stress above the second elastic limit.

Eyewear device includes an eyeglass frame, a temple, and a coupling device for hingedly coupling the temple to the eyeglass frame, formed of an elastically deformable material, and including a single flexible arm of an elongate shape and a front end portion positioned and retained against the front surface of the eyeglass frame. The single flexible arm extends from the front end portion into a slot in the frame and an internal elongate slot in the temple positioned in opposing alignment therewith. The elasticity of the coupling device flexibly, hingedly couples the temple to the eyeglass frame and allows a temple that has suffered inordinate bending moments and directions to instantly return to nominal use by retightening or replacing the coupling device, and/or by repositioning the temple to properly abut the eyeglass frame.

Examples of the present disclosure are related to systems and methods associated with glasses. More specifically, embodiments are related to glasses with separable arms with a triangular shaped support, wherein a first portion of an arm is separable from a second portion of the arm at a location that substantially aligns with a user's temple.

A screwless hinge system for connecting a temple to a front frame portion of eyewear includes a hooked tab with a single hook and a base. The hooked tab extends through the front frame portion and a u-spring until the base engages the frame. A temple receiver of a temple compresses the u-spring and engages the single hook, allowing for opening and closing of the temple and removal and replacement of the temple without tools.
