PIVOT ASSEMBLY AND EYEGLASS FRAME Russian patent published in 2021 - IPC G02C5/22 

FIELD: glasses.

SUBSTANCE: invention relates to the field of technical application of glasses and, in particular, to the pivot assembly and the eyeglass frame. A pivot assembly is proposed, comprising guide case (30), first connecting element (60), second connecting element (70), first spring (40), and second spring (50). Guide case (30) comprises first end surface (31) and second end surface (32) provided on opposite sides. First guide slot (33) intersects orthogonally with second guide slot (34). First connecting element (60) has first connecting end (61) protruding from the end surface of end part (10). Second connecting element (70) has second connecting end (71) protruding from the end surface of the end of earpiece (20). First connecting end (61) and second connecting end (71) are pivotally connected in guide case (30) and act as a rotational axis for each other. Eyeglass frame (100) contains end part (10), earpiece (20) and the pivot assembly. The pivot assembly and eyeglass frame (100), the connecting ends of the two connecting elements of which are pivotally connected in guide case (30) and act as a rotational axis for each other, ensure smooth rotation and return to the initial position and prevent jamming.

EFFECT: creation of a pivot of the eyeglass frame with a smoother rotation and return of the earpiece, which increases the service life.
