SWIVEL GLASSES (OPTIONS) Russian patent published in 2018 - IPC G02C7/16 

FIELD: optics.

SUBSTANCE: invention relates to optics, namely to glasses. Claimed swivel glasses comprise a fixed frame having right and left lateral ends, a nose bearing connected to said fixed frame, substantially equally spaced from its lateral ends, movable frame having right and left lateral ends comprising at least two optical elements, upper and lower left arms, upper and lower right levers, in which each of said arms has a distal and proximal ends. Said right and left arms with their proximal ends at a distance from each other along the vertical axis are hingedly connected to said right and left lateral ends of the fixed frame, respectively, and with their distal ends, said right and left levers at a distance from each other along a vertical axis are pivotally connected to said right and left lateral ends of the movable frame, respectively. Said right arms and said left arms together with the hinge parts of the right and left lateral ends of the movable and fixed frames, with which they are connected, form flat four-link lever mechanisms, the planes of which are essentially parasagittal.

EFFECT: creation of glasses for permanent wearing with the possibility of using them in several versions of the working position.
