A pair of eyeglasses includes a lens body having two engaging grooves formed in left and right sides thereof and respectively having an engaging section, and two quick release mechanisms detachably disposed on the left and right sides of the lens body and each including a positioning member defining a positioning slot and a receiving hole, an engaging member detachably engaged to the engaging section of a respective engaging groove and having a slide piece portion and a stop block portion, and a connecting member disposed on rear sides of the positioning member and the engaging member. When the engaging member of each quick release mechanism is pressed into the positioning member, the slide piece portion is located in the positioning slot and the stop block portion is received in the receiving hole to allow detachment of each quick release mechanism from the lens body.

Spectacles and a hinge assembly thereof are provided. A hinge assembly includes a first connecting portion, a reinforcing portion, and a second connecting portion. The first connecting portion has a recessed structure. The reinforcing portion at least partially covers an inner wall of the recessed structure, and a strength of a material of the reinforcing portion is greater than a strength of a material of the first connecting portion. The second connecting portion is inserted into the recessed structure and is rotatable with respect to the first connecting portion.

A screw part has a shank with a threaded portion having at least one external thread turn, and a sleeve that surrounds the shank in a circumferential direction around more than three-fourths of the circumference. The sleeve extends along a sleeve portion in a longitudinal direction of the shank. The sleeve has at least one radial elevation structure on an outer circumferential face. The at least one radial elevation structure has at least one structural element that has an elastic design in the radial direction. The at least one radial elevation structure has an extent, on the outer circumferential face of the sleeve along the longitudinal direction, that is greater than a width of the at least one structural element.

The present disclosure provides eyeglasses including: an eyeglass rim; an eyeglass temple, the eyeglass temple comprising a control circuit or a battery; a rotating shaft, the rotating shaft being configured to connect the eyeglass rim and the eyeglass temple, so that the eyeglass rim and the eyeglass temple are relatively rotated around the rotating shaft, and the rotating shaft being disposed with a rotating shaft wiring channel along an axial direction; and a speaker, the speaker comprising an earphone core, the speaker being connected to the eyeglass temple, the control circuit or battery in the eyeglass temple driving the earphone core to vibrate through the connection wire, wherein the earphone core vibrates to generate a driving force to drive a housing panel of the speaker to vibrate, and a straight line of the driving force being not parallel to a normal line of the housing panel.

The present disclosure embodiment may disclose a glasses including a glasses frame and two speakers. The glasses frame may include a glasses rim and two glasses temples. The two glasses temples may be rotatably connected to the glasses rim, respectively. The two speakers may include an earphone core. The two speakers may be connected to the two glasses temples via hinge components of the two glasses temples, respectively. The hinge components may be rotatable to change a position of each of the speakers relative to connected one of the glasses temples. The glasses temple may include a circuit component or a battery to drive the earphone core to vibrate to generate a sound. In the present disclosure, the glasses rim and the glasses temple may be connected through a rotating shaft, thereby protecting the connection wire in the glasses and extending the life of the connection wire.

Elastic hinge for eyeglass frames, which comprises an articulation screw engaged in the holes of two articulation elements. The articulation screw comprises a shank provided with a narrow portion, which is engaged in the hole of a first tab of an articulation element, and with an enlarged annular portion, which forms a step and is engaged in the hole of a head portion of the other articulation element. The articulation screw assumes an end stop position, in which it is tightened and aligned with the hinging axis, and a blocking position, in which it is loosened and is tilted with respect to the hinging axis in response to the elastic force exerted by an elastic device, such that the step of the articulation screw interferes with the edge of the hole of the first tab of the articulation element, preventing a further unscrewing of the articulation screw.

Process for assembling an elastic hinge for eyeglass frames comprising a first articulation provided with a head with a first hole, a second articulation having two shoulders provided with second holes, and a pin having a stem provided with a thinned final portion. The process provides for inserting the head of the first articulation between the two shoulders of the second articulation with the first hole of the first articulation non-aligned with respect to the second holes of the second articulation, an opening thus remaining between such holes. A step for inserting the pin is provided, during which the thinned portion of the pin is wedged in the aforesaid opening between the holes and is screwed into one of the second holes of the shoulders of the second articulation.

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.

Some embodiments are directed to a hinge for spectacles including an optical frame front and at least one temple linked to a tenon of the optical frame front, the hinge including a first part linked to the tenon and a second part linked to the temple, the first part and the second part being linked by a link device mounted along an axis of the hinge and being movable between an open position and a closed position; when passing from the open position to the closed position, an opening is formed between the outer surfaces of the first and second parts. The first and second parts each include a conduit opening opposite each other in the open position, and the hinge includes a hinge member mounted along the hinge axis between the first part and the second part.

Process for mounting an elastic hinge on an eyeglass frame, which provides for fixing a first pivot element to a first component of an eyeglass frame, for fixing a second pivot element to a second component of the eyeglass frame, and for engaging a hinge pin within first holes of the first pivot element and within second holes of the second pivot element, wherein a thinned portion of the hinge pin interferes with two head portions of the first pivot element in order to align the first holes of the first pivot element with the second holes of the second pivot element.
