Method for the assembly of elastic hinges on an eyeglass frame, wherein each elastic hinge has a first and a second articulation elements hinged around a hinging axis. The method provides for a first step of inserting the first articulation element in a first seat of a temple and, subsequently, a second step of inserting the second articulation element in a second seat of an end piece of the eyeglasses. In the first insertion step, the second articulation element is placed perpendicular to the first articulation element with the hinging axis placed at a first distance from the temple. Before the second insertion step, a tensioning step is provided in which the second articulation element is rotated up to being arranged parallel to the first articulation element, bringing the hinging axis to a second distance from the temple that is greater than the first distance.

A head mounted wearable computing device includes a frame including arm portions rotatably coupled to a front frame portion, with electronic components housed in and/or on the front frame portion and the arm portions. Cables run through hinge mechanisms rotatably coupling the arm portions and the front frame portion for connection of electronic components in the arm portions and the front frame portion. The hinge mechanism includes a dual pivot structure that guides the bending of cables through the hinge mechanism through approximately 90 degrees of bending through two pivot points. The dual pivot structure reduces localized strain on the cable through the range of motion of the hinge mechanism. The dual pivot structure allows for a rotation through the range of motion with little to no extra cable length to accommodate the bending of the cable.

Elastic hinge for the plastic frame of eyeglasses, which comprises a first articulation element and a second articulation element, wherein the first articulation element comprises a box-like body provided with a seat and a carriage provided with a rod-like element inserted in the seat and with a head externally projecting from the seat and coupled with the second articulation element. A bush is slidably mounted on the rod-like element, and a spring thrustingly acts on such bush. A fork-shaped body is inserted from the outside into a hole of the box-like body and is engaged with the bush in a straddling manner in order to retain the latter with respect to sliding along the longitudinal axis of the rod-like element.

Elastic hinge for eyeglass frames, provided with two pivot elements hinged together by means of a pin. A first pivot element is provided with an elastic device comprising a carriage provided, at an external end thereof, with a head portion having a first hole which is extended passing between its two lateral faces. A second pivot element comprises two shoulders provided with second holes and delimiting a slit between them in which the head portion is inserted. The head portion comprises a tilted slide surface, which is extended towards the external end of the carriage on at least one of the lateral faces of the head portion directed towards the head of the pin, covering at least one area adjacent to the first through hole.

An elastic hinge for eyeglasses includes: a box-shaped housing with an inlet aperture; a fork carriage, slidably mounted in a guiding cavity inside the box-shaped housing opposing an elastic element; and an elastic holding clip, snap-engageable with a retaining structure of the housing cavity, against which one end of the elastic element abuts. The elastic holding clip is generally C-shaped, providing a resting arm and a flexible arm joined by a connecting portion, the flexible arm having an engaging unit to snap-engage with the retaining structure, the resting arm and flexible arm elastically biased one towards the other by inner walls of the housing. The flexible arm is integral with at least one bias element, accessible from an inlet aperture of the housing, defining bias planes to be engaged with a tool, introduced via the inlet, for imparting a disengaging bias, bending the flexing arm towards the resting arm.

A spectacle frame including a front face for supporting the lenses and temples connected to the front face by means of hinges, each including an attachment member, respectively rigidly connected to the front face and to the temples, each receiving a hinging member, having its free end provided with a hinge pin, said hinge pins being perpendicular to each other. The attachment members are hollow and define a cylindrical sheath. The hinging members each include a rod, intended to be received in the respective sheath, one of the ends of the rod being provided with an abutment and the other end being provided with said hinge pin, each of the rods receiving a sliding ring submitted to the action of a spring bearing against the abutment, said ring being rigidly connected to the corresponding attachment member near the free end thereof. The hinge pins of the hinging members are rigidly connected to each other by means of a connection member.

Provided herein is a flexible hinge comprising a tension spring (1), a sliding element (2), a sliding element guide (3), a spring tensioner (4), a stop (5) for stopping the longitudinal movement of the sliding element (2), a fastener (6), and a bearing shield (7). The flexible hinge disclosed herein can be installed in a pair of eyeglasses comprising a pair of temples and a frame front so as to connect the temples to the frame front. The flexible hinge can be fixed to the temple with the stop (5) at one end and to the frame front with the fastener (6) at another end. The fastener (6) is used to engage sliding element (2) with the bearing shield (7). The sliding element guide (3) enables longitudinal movement of the sliding element (2) along the x-axis and prevents its movement along other axes.

Elastic hinge for the plastic frame of eyeglasses, which comprises a first articulation element and a second articulation element, wherein the first articulation element comprises a box-like body provided with a seat and a carriage provided with a rod-like element inserted in the seat and with a head externally projecting from the seat and coupled with the second articulation element. A bush is slidably mounted on the rod-like element, and a spring thrustingly acts on such bush. A fork-shaped body is inserted from the outside into a hole of the box-like body and is engaged with the bush in a straddling manner in order to retain the latter with respect to sliding along the longitudinal axis of the rod-like element.

An elastic hinge for spectacle frames and manufacturing method thereof are disclosed, wherein the hinge includes a fork female component and an eyelet male component mutually hinged, the male component including at least one carriage slidingly fit in a cavity housing of a box-shaped body in contrast with an elastic element constrained with respect to the box-shaped body by way of a locking clip being provided with an annular collar which encircles a stem portion of the carriage, arranged between one end of the elastic element and a rear abutment end surface of a guide portion of the carriage. At least a groove is formed in the guide portion, adjacent to the perimeter profile of the stem portion, having a depth in the direction of the longitudinal axis of the carriage, defining a seat wherein at least a substantial part of the annular collar is engaged.

A hinge for a spectacles frame, comprising a front face element, a side element and a connecting element connecting said front face element to said side element, said connecting element comprising a base member, mounted in the side element, and a head member, housed in a cavity in the front face element so as to allow the side element to be open/closed about a vertical first axis of articulation and so as to allow the side element to be inclined about a horizontal second axis of articulation, the front face element comprises at least one internal end stop member extending into said cavity so as to limit the movement of the side element about the horizontal second axis of articulation.
