The present invention relates to a pair of glasses with polarized or prescription lenses that can be adjusted to provide two different looks. Rotatable side arms connected to the main frame through a leg seat and a rotating secondary frame provide a mechanism to interchange the interior and exterior sides of the glasses. A correct lens orientation indicator on the secondary frame ensures correct configuration. In addition, the proposed mechanism offers two folding styles. In the first one both side arms are folded next to each other at the same side of the main frame. In the second, the side arms are folded on opposite sides of each other. Furthermore, the present invention provides a simple mechanism to turn smart glasses on and off. If the camera placed on the side arm is facing outwards, the smart glasses turns on. When the camera faces inwards, the smart glasses turns off.

An apparatus for releasably attaching a temple to a lense frame. In one aspect, the inventive apparatus comprises: a grasping mechanism, at the forward end of the temple, for releasably, pivotably, and directly grasping a hinge pin provided on the lense frame, and a finger-operatable actuator for actuating the grasping mechanism to selectively release and pivotably grasp the hinge pin. When the grasping mechanism is secured to the hinge pin, the forward end of the temple will preferably be positioned directly adjacent to the lense frame such that the grasping structure is substantially hidden from outside view. Alternatively, the apparatus can comprise: an insert structure pivotably attached to the lense frame; a cavity provided in the forward end of the temple for receiving the insert structure; and a catch mechanism for releasably retaining the insert structure in the cavity. When the insert structure is retained in the cavity, the forward end of the temple will preferably be positioned directly adjacent to the lense frame such that the insert structure is substantially hidden from outside view.

Ein Bügelendstück für einen Bügel einer Brillenfassung weist einen in Verlängerung des Bügelschaftes verlau­fenden ersten Abschnitt und einen unterhalb desselben angeordneten, gekrümmten Anlageabschnitt auf. Der Anla­geabschnitt wird an seinem unteren Ende abgestützt mittels eines vom ersten Abschnitt nach hinten und unten verlaufenden Verbindungsabschnitts, wobei zwi­schen den unteren Enden des Anlage- und Verbindungsab­schnitts ein widerstandsarmes Gelenk ausgebildet ist. An seinem oberen Ende ist der Anlageabschnitt mit dem ersten Abschnitt über ein federelastisches Element verbunden, das einer Drehbewegung des Anlageabschnitts im Gelenk eine gewisse Federkraft entgegensetzt. Der erste Abschnitt, der Verbindungsabschnitt und auch der Anlageabschnitt können unter Berücksichtigung der erforderlichen Formsteifigkeit des Bügelendstücks verhältnismäßig kräftig dimensioniert werden. Durch das Gelenk ist dennoch für ausreichende Bewegbarkeit des Anlageabschnitts gesorgt. Durch das federelastische element kann für geringe Federkräfte und somit eine angenehm weiche Anlage des Anlageabschnitts gesorgt werden.

The present invention relates to a wavy structure of a spectacle frame, and the technical object of the present invention is to provide a wavy structure of a spectacle frame which is compatible to multiple different lenses, is convenient to install, and is firm and stable when in use. The wavy structure of the present invention includes a spectacle lens frame and frame temple, and an inner ring of the spectacle lens frame is shaped as a wavy structure. The present invention not only has elasticity and can be compatible to lens of different models, but also can firmly stabilize the lens, and is applied to the production and use of man-rated spectacle field.

An apparatus for releasably attaching a temple (106) to a lense frame (110) commprises an insert structure (102) pivotably attached to the lense frame; a cavity (108) provided in the forward end of the temple for receiving the insert structure; and a catch mechanism for releasably retaining the insert structure in the cavity. When the insert structure is retained in the cavity, the forward end of the temple will preferably be positioned directly adjacent to the lense frame such that the insert structure is substantially hidden from outside view.

An elastic hinge (10) for eyeglasses, comprising an elongated box-like body (11, 211) provided with an open receptacle (13) inside which a traction elastic element (14, 214) and a first hinge articulation element (16) associated with the elastic element are inserted with the first hinge articulation element arranged to slide and pivoted to a second hinge articulation element (17) for fixing to the eyeglasses; the first and second ends (20, 21) having both a larger diameter than the intermediate body of the elastic element; a longitudinal milling (26) extending on the entire length of the box-like body (11, 211), and being provided with an axial hole (27); the length of the elastic element (14, 214) when inactive being substantially equal to the distance between the bottom of the axial hole (27) and the end (26a) of the milling (26).

An elastic hinge (10) for eyeglasses, comprising a female element (11), which is coupled to the front of the eyeglasses (12) and in which a bulbous wider head portion (13) of a male element (14) engages so as to provide articulation; the head portion of the male element is coupled with sliding friction contact on corresponding shoulders (16) formed within the female element (11), at the temple end, by a slot thereof through which the body of the male element passes; the hinge further comprises elastic elements (25) arranged within a recess of the temple, in which the male element is partially inserted, which act by traction between the male element and the bottom of the recess and move the head portion of the male element into abutment on the shoulders, generating contact coupling and moving the front surface of the temple into abutment on the front surface and the lateral surface of the female element.

Each temple bar (1) is connected to the face (2) of the spectacles via a respective hinge (3) that is coupled to an extra-opening mechanism comprising an enclosure (4) attached to the temple bar. An extension spring (14) extends in a through-hole (10) of the enclosure (4) and comprises a hook-shaped front end portion (15), which is surrounded by a containment ring (8) protruding from the front end portion of the enclosure (4) so as to form an eyelet (9) along which there is adapted to slide a pin (23) of said hinge (3) as engaged by said hook (15).
