DUAL-AXIS HINGE MECHANISM
20240184134 · 2024-06-06 ·

Eyewear includes a frame connected to an arm using a hinge mechanism that enables movement of the arm to a folded position, a nominal position, and a hyperextended position. In the nominal position, gaps and exposure of any electronic components of the eyewear are minimized or eliminated. A hinge with multiple axes of rotation of different parts allows the arm to automatically snap between multiple stable positions relative to the frame while also being able to flex and apply a clamping force to a wide array of heads. A cable or other electrical connector can extend through a portion of the hinge to protect and guide the cable between electronic parts in the arm and frame.

EYEWEAR AND FLEXIBLE ELEMENTS

The present disclosure relates to eyewear, such as eyeglasses, configured for receiving a hose, such as a medical gas therapy hose. The eyewear comprises flexible elements and a groove defined in and extending through the flexible elements and other parts of the eyewear. The present disclosure further relates to a flexible element, such as a hinge, which may be used in eyewear to enable bending of parts of the eyewear. An exemplary embodiment of the flexible element is a hinge having a plurality of repeating units.

The present invention generally concerns a one piece eyewear having concealed hinges made via 3D printing. More specifically, the invention includes a U-shaped hinge with irregular offsets that are blended parametric curves that connect a lens frame to temple bars. The hinge is most flexible at its parabolic cross section and allows the temple bars to open and close, mimicking the rotational and stress bearing properties of traditional mechanical hinges. The eyewear is sculpted in a 3D modeling program that exports digital instructions for rendering the hinges, lens frame, and temple bars as a single construct by a 3D printer. The one piece eyewear is capable of accepting prescription or non-prescription lenses. A method for making the eyewear having concealed hinges is also disclosed.

FRAME FOR SPECTACLES

A frame for spectacles comprises a front mount (2) having respective lateral lugs (4) which are provided for the articulation of respective arms (5) for the purpose of producing the articulated connection of each arm (5) to the front mount (2); each lug (4) comprises a first lug portion (4a) which extends into a second lug portion (4b) which is folded on the first portion in a position facing the first portion, the second portion (4b) comprising a first through-opening (8) which is laterally delimited by a pair of opposing wings (9a, 9b) which are spaced apart from each other, the wings being connected at the free end of the second lug portion (4b) by a cross-member (10), an extension piece (11) which extends from the cross-member (10) inside the opening (8) and in the direction of the first lug portion (4a).

EYEWEAR FRAMES AND PRODUCTION METHOD
20180180901 · 2018-06-28 ·

The invention relates to an eyewear frame, comprising a forehead part with two ends and arranged to extend around the eyes of a user when worn and two temple parts each extending rearwardly from a front of the eyewear frame, and from each end of the forehead part. The forehead part and the temple part being moulded together in a single mould from a first polymer material and comprising a plastic hinge located at the junction of each end of the forehead part and each temple part, said plastic hinge being formed by a region of the polymer material having thickness which is significantly less than the thickness of corresponding forehead part ends and temple parts adjacent the plastic hinge region, such that the temple parts may be moved about the plastic hinge with respect to the forehead part between an open position in which the eyewear may be worn on a user's head, and a closed position in which the temple parts are arranged approximately parallel to the forehead part and the eyewear may be more conveniently stowed when not in use. The plastic hinges exert a restoring force which urges the temple parts of the frame to either the closed or open position, such that the eye wear frame automatically folds back to the folded position after use, or automatically opens to the open position. The plastic hinge may be formed as a curved strip. The eyewear frame may be co-moulded with the first polymer material and a second polymer material, having a lower modulus of elasticity, or flexural modulus, than the first polymer.
