Provided is an eyeglass frame that includes a hinge with which a reduction in size and a reduction in weight can be achieved, and stable open/close operations can be performed over a prolonged period of time. The eyeglass frame includes a lens holding portion 2, a temple 3, and a hinge 5 that enables pivoting of the lens holding portion 2 and the temple 3. The hinge 5 includes a terminal portion 21 of the lens holding portion 2, a terminal portion 31 of the temple 3, and a coupling portion 4 that couples the two terminal portions. The terminal portion 31 of the temple 3 is selectively positioned with respect to the coupling portion 4 at a position when the temple 3 is completely open and at a position when the temple 3 is folded.

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.

A wearable device includes a frame, two feet, and two pivoting modules. Each of the pivoting modules includes a first bracket fixedly connected to the frame, and a second bracket fixedly connected to one of the feet and pivotally coupled to the first bracket. The second bracket includes a positioning member and an inserting member. The positioning member is located in the first bracket, and the positioning member includes a plurality of slots. The inserting member is switchably inserted into one of the slots for adjusting a maximum outreaching volume from the frame to the feet.

The present invention discloses a detachable nose pad assembly for eyeglasses which comprises a nose pad having a socket for detachably assembling to a middle region of a frame, and a mounting stand disposed on the frame and corresponding to the socket. The mounting stand has a U-shaped flexible member having an upper clipping portion and a lower clipping portion disposed thereon for inserting into the socket, two notches disposed at two laterals of the U-shaped flexible member respectively and two supporting ribs respectively extended from an outside of each of the two notches. The socket has a concave groove for engaging with the lower clipping portion and a U-shaped wall formed at an end surface thereof for correspondingly inserting into the two notches and positioned by the two supporting ribs.

Eyeglass frames include a face member and two temple members connected to the face member. The face member includes a rim with a brow configured to retain at least one lens. A nose member is connected to the face member and supports the rim separated from a face of a wearer by a gap. A vent passage is provided in the brow and extends from a front portion of the brow to a rear portion of the brow. A vent adjustment member provided on the brow directly above the at least one lens. The vent adjustment member is configured to move between a first position wherein the vent passage is substantially closed and a second position wherein the vent passage is open. The vent adjustment member is substantially flush with a medial portion and a lateral portion of the brow when the vent adjustment member is in the first position and offset from the medial portion and lateral portions of the brow when the vent adjustment member is in the second position.

A head-mounted display device includes a display portion, a main frame, two arms, and two adjusting pieces. The main frame carries the display portion. The arms are disposed on opposite sides of the main frame, and the end portions of the arms are pivotally connected to the main frame such that the arms are adapted to rotate away from the main frame during an unfolding process and adapted to rotate toward the main frame during a folding process. The adjusting pieces are respectively disposed on pivot paths of the arms, and the adjusting piece is adapted to from a structural interference with the corresponding arm and the main frame during the unfolding process to limit a degree of rotation of the arm.

Dual-frame eyeglasses that include a foundation eyeglass frame that may be worn on the user's head, and a pivot eyeglass frame that is rigidly coupled to the foundation eyeglass frame via a pair of pivot mechanisms. The pivot eyeglass frame may be substantially similar in form and profile to the foundation eyeglass frame. The pivot eyeglass frame may be configured to incrementally rotate about the pivot mechanism from a first position that substantially overlaps a user's line of sight through to a second position that is angularly offset away from the user's line of sight. Additionally, the foundation eyeglass frame may include a nose bridge that separates into two elements at a coupling point on the nose bridge to facilitate each half of the foundation eyeglass frame folding into a separate, compact form.

Aspects of the present invention relate to a head-worn computer having a see-through computer display, a frame mechanically adapted to hold the see-through computer, a first side arm pivotally attached to the frame and adapted to hold the head-worn computer in place on a head of the user, wherein the first side arm comprises a temple section and an ear horn section and the temple section further comprising a compartment adapted to contain a battery, wherein the battery powers the see-through computer display.

In some examples of the disclosure, a head-worn computer is disclosed. In some examples, the head-worn computer comprises a first side arm comprising a temple section and an ear horn section, the temple section comprising a first-side securing attachment system, and the ear horn section comprising a second-side securing attachment system adapted to mate with the first-side securing attachment system, wherein the first-side and second-side securing attachment systems are adapted to secure the ear horn section to the temple section with a rotation of a pin member, wherein the rotation mechanically interconnects the pin member with a pin securing mechanism.

Aspects of the present invention relate to a head-worn computer, comprising a removable and replacable 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 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.
