Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 283 words
An optical frame comprising a lens bow, two temples, hinge joints connecting the temples to the lens bow; each temple having a stop face on one end to rest against the lens bow, and an elastic cushion arranged in the region of each hinge joint between the lens bow and the stop face of the temple and wherein: the elastic cushion comprises a base plate and an elastic portion arranged on the base plate at an angle of less than 90 degrees and overlapping the outside edge of the lens bow, the lens bow has a recess and the elastic cushion is set in the recess, the thickness of the elastic cushion is greater than the depth of the recess, the base plate has an opening, the lens bow has a first part of the hinge joint thereon in the form of a solid journal bearing which passes through the opening in the base plate, the end of the temple has a second part of the hinge joint thereon and the base plate has a projection resting under elastic pretension on the second hinge part, the second hinge part has an arc-shaped braking area and the projection has a concave pressure surface, the base plate runs parallel to the plane of the lens bow, and the temple has a straight extension part at its end which, when the temple is open, overlaps the outside edge of the lens bow, the stop face is arranged on the side of the extension part facing towards the outside edge of the lens bow, and the stop face rests on the elastic portion arranged on the base plate to overlap the outside edge of the lens bow.
