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.

An extended reality (XR) head-mounted display (HMD) device may include a processor; a memory device; a power management unit; an HMD video display to present to a user an extended reality image of an environment; an HMD housing fitted to be formed around a user's eyes; and a swappable nose bridge, including: a nose bridge extension to fit within a nose bridge slot formed into the HMD housing; and a nose bridge magnet formed at the nose bridge extension to magnetically engage within the nose bridge slot formed in the HMD housing.

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).

Magnetic Bluetooth eyeglasses are revealed. A Bluetooth circuit module is mounted in a mounting space of a temple and provided with a built-in Bluetooth unit connected to mobile devices. The Bluetooth circuit module further includes a microphone, a speaker, a touch switch, and a power connection base. The temple is connected to a power supply device by magnetic attraction between first and second magnetic members while the power supply device is in contact with the power connection base of the Bluetooth circuit module. Thereby users are not bothered by wires while in use and the eyeglasses are more convenient to use. Moreover, the eyeglasses can still be used during charging process. Users only need to replace the power supply device with a new one already charged instead of taking off the whole eyeglasses. The eyeglasses which prevent moisture infiltration provide longer service life.

An eyewear hinge device may include a first assembly having a first and second pin bridge which may both be coupled to a first object. A friction plate may be coupled to the first object and positioned between the pin bridges, and the friction plate may extend toward the stop plate. A first channel may extend around the friction plate. The friction plate may comprise a friction pocket and a friction ridge. A second assembly having a first and second lock arm may be coupled to a second object. The first lock arm may have a first lock pin and a first arm extension, and the second lock arm may have a second lock pin and a second arm extension. The first assembly may be movably coupled to the second assembly by positioning the first lock pin in the first pin aperture and the second lock pin in the second pin aperture.

A frame includes: a pair of lens-holding frames each holding lenses that are vertically arranged; a bridge coupling the pair of lens-holding frames; a temple attached to an outer periphery of each of the lens-holding frames; nose pads being brought into contact with a nose for support; a vertical movement unit configured to vertically move the lens-holding frames along a front bent portion of the temple; and a nose pad elevation unit provided to the bridge, the nose pad elevation unit being configured to vertically slide the nose pads. The bent portion is configured to align a center of the lens with an eye level.

An eyewear assembly is provided. The eyewear assembly includes a continuous lens part having a curved shape that extends from a first end to a second end. The eyewear assembly further includes a pair of temple retention arms hingably coupled to the continuous lens part. Each of the pair of temple retention arms is configured to pivot between a closed position and an opened position, and each of the pair of temple retention arms is configured to contact a temple of a user to retain the eyewear assembly on the user.

A frame for spectacles includes a frontal framework with lateral lugs for articulation of arms and means of articulation between each lug and the corresponding arm. The articulation means include a flexible member, structurally independent of the lug and the arm, the flexible member being held on the arm and coupled rotatably, the end of each arm, facing the corresponding lug, shaped in such a manner that the arm, in its movement about the hinge pin, is flexibly constrained towards preselected angular positions relative to the frontal framework. The frame also includes a respective distance element interposed between each arm and the corresponding flexible member, and said distance element is mounted on the arm in an adjustable manner in order to impose, at the level of said distance member, a preselected distance between the arm and the flexible member, and to regulate a flexible pre-load exerted on the flexible member.

A pad assembly adapted to be mounted in a caliper body for a disc brake has a pad-housing pocket. The disc brake defines an axial direction, either coinciding or parallel with the direction of the rotation axis of the brake disc associable with the caliper body, a radial direction (R-R), orthogonal to the axial direction, and a tangential (T-T) or circumferential (T-T) direction, orthogonal both to the axial direction and to the radial direction (R-R). The pad-housing pocket has at least one pocket wall to form a tangential abutment for a brake pad associable with the caliper body. The pad assembly has a brake pad having a support plate, adapted to form a support for at least one associable friction material, where the support plate has a main extension along the radial (R-R) and tangential (T-T) directions. The support plate has a predefined bulk along the tangential direction (T-T), or tangential bulk, such that the support plate is adapted to be accommodated with a predetermined tangential play in the pad-housing pocket. The pad also has at least one elastic element.
