The eyeglasses frame includes a first hinge barrel provided on a lens holding portion, a second hinge barrel provided on a temple, a first screw that pivotably couples the first hinge barrel and the second hinge barrel, and a second screw provided in the second hinge barrel and contactable with the first hinge barrel. A tip portion of the first hinge barrel is a cam that includes a first depression where the second screw comes to rest when the eyeglasses frame is completely open, a second depression where the second screw comes to rest when the eyeglasses frame is completely closed, substantially straight portions that join the first and second depressions, and a corner portion where the substantially straight portions change direction at a point therebetween.

The present invention relates to a novel screw that causes drag and prohibits unwinding of the screw. The screw is designed for use in eyeglasses for securing eyeglass lenses and prohibiting same from falling out. The screw includes a fillister head, a drive disposed on the head for engaging a screwdriver, a shaft running from the head to a terminal end, the shaft having non-contiguous circumferential threads along the length of the shaft for rotatably sliding the screw through slots. The screw includes a longitudinal channel in the form of a slot disposed along the surface of the shaft and through the length of the shaft. A planar bar of neoprene or any other polypropene can be inserted in the channel which assists with prohibiting unwinding of the screw when the screw is in use.

What is described is a hinge device for connecting the sides (2) to the fronts of spectacle frames (4), comprising a first and a second hinge element (6, 7) pivoting about a hinge axis (X), the first element (6) comprising a substantially fork-shaped body (8) with a first and a second arm (9, 10) opposed to one another, between which the second hinge element (7) is interposed, and a screw means (16) forming a hinge pin, passing through respective holes formed coaxially in the first and the second hinge element (6, 7), so as to be, respectively, locked by a screw engagement in the first hinge element (6) and housed rotatably in the second hinge element (7). The device further comprises at least a first anti-seizing sleeve (18) provided in the hole (13) of the second hinge element (7) and capable of being engaged by the hinge screw (16) in a rotatable coupling, the sleeve (18) comprising at least a first surface (20) extending in a contact area and capable of relative sliding between the hinge elements (6, 7), at least one ring (22) of elastically flexible material, fitted on the hinge screw (16) and capable of being deformed elastically as a result of the tightening of the screw so as to exert a relative pressure between the first and the second hinge element (6, 7), thereby increasing the friction provided between the hinge elements, and at least one bush (23) mounted in a seat of the first hinge element (6), coaxially with the hinge screw (16), and capable of accommodating the ring (22), the bush (23) including at one of its axial ends a bearing shoulder (24) for the ring (22), and being capable of making contact with the first surface of the anti-seizing sleeve (18), so that the bush (23) is biased axially against the sleeve (18) by the elastic action generated by the friction ring (22) as a result of the tightening of the hinge screw (16).

The eyeglasses frame includes a first hinge barrel provided on a lens holding portion, a second hinge barrel provided on a temple, a first screw that pivotably couples the first hinge barrel and the second hinge barrel, and a second screw provided in the second hinge barrel and contactable with the first hinge barrel. A tip portion of the first hinge barrel is a cam that includes a first depression where the second screw comes to rest when the eyeglasses frame is completely open, a second depression where the second screw comes to rest when the eyeglasses frame is completely closed, substantially straight portions that join the first and second depressions, and a corner portion where the substantially straight portions change direction at a point therebetween.

A hinge structure of smart glasses is provided, comprising several hinge frames provided along a pre-set direction, adjacent hinge frames are hinged by a hinged shaft; the hinged shaft is provided with a reset assembly, and after the hinge frame at one end swings to a pre-set angle toward a pre-set outward flipping direction relative to the hinge frame at the other end, the reset assembly provides a reset force to the hinge frame, so that the corresponding hinge frame has a motion tendency opposite to the pre-set outward flipping direction; the hinged shaft is provided with a damping elastic piece, and the damping elastic piece presses against at least one hinge frame so as to provide a damping force thereto when the corresponding hinge frame swings.

The present invention relates to a frame for spectacles 10 which comprises a front piece 12 and at least one side arm 13 which are hinged together by means of a hinge structure 14. The hinge structure 14 comprises a first hinge part 15 and a second hinge part 16 which are pivotably joined together by means of a pivoting screw 21. In accordance with the invention, the second hinge part 16 comprises a reinforcing element 23 with a fixing base 24 which is fixed inside a locking groove 26 by means of a form-fit joint.

The present disclosure provides glasses including: a glasses rim; a glasses temple comprising a control circuit or a battery; a rotating shaft configured to connect the glasses rim and the glasses temple, so that the glasses rim and the glasses temple are able to relatively rotate around the rotating shaft, the rotating shaft being disposed with a rotating shaft wiring channel along an axial direction; a connection wire passing through the rotating shaft wiring channel and extending to the glasses rim and the glasses temple, respectively; a speaker comprising an earphone core and being connected to the glasses temple, the control circuit or the battery driving the earphone core to vibrate to generate a sound through the connection wire; and at least two microphones disposed in the glasses temple or the speaker, the at least two microphones being located at positions with different distances from a mouth of a user.

A pair of eyeglasses is provided with an eyeglass frame, from which a left and a right eyeglass lens of the eyeglasses is held, and with two eyeglass temples connected to the eyeglass frame, wherein the left lens is arranged between an upper frame element and a lower left frame element of the eyeglass frame and the right lens is arranged between the upper eyeglass frame section and a lower right frame element of the eyeglass frame. In a left temple fastening region, the upper frame element and the lower left frame element extend along a common left extension direction and can are releasably fastened to one another by means of a left screw connection, which extends along a left connecting direction. In a right frame fastening region, the upper frame element and the lower right frame element extend along a common right extension direction and can be releasably fastened or are releasably fastened to one another by means of a right screw connection, which extends along a right connecting direction. The left connecting direction and the left extension direction form a left acute angle (-l) of at least 8 in a top view onto the eyeglasses from the top. Alternatively or additionally, the right connecting direction and the right extension direction form a (right) acute angle (-r) of at least 8.

The embodiment of the present disclosure discloses a wearable device, including: a wearing part including: a connection section and a concave section, the concave section being connected to the connection section. The concave section causes an upper edge of the wearing part to have a downward depression on the wearing part; the concave section is provided with an acoustic output end inside.
