Method for making a central piece of a flexible full-rim frame for eyeglasses
First Claim
1. A method for making a central piece of a full rim frame with lenses for eyeglasses, wherein the central piece has a left full rim including an inner side, and an end piece;
- a right full rim including an inner side, and an end piece; and
a bridge for joining the left and right full rims, the method comprising;
a) creating a left and a right eyeglass lens wherein the left and right lenses each have a peripheral contour shape;
b) creating the central piece wherein the left and right full rims are flexible and each has a contour shape that is different from the peripheral contour shape of the respective left and right lens; and
c) inserting the left and right lenses into the respective left and right full rim whereby each rim elastically receives and retains the respective lens, thereby generally conforming to the peripheral contour shape of the respective lens.

Abstract
The central piece of a full-rim eyeglass frame includes a left full rim (2) for receiving a left lens, a right full rim (4) for receiving a right lens, a bridge (6) joining the two full rims, and two endpieces (8, 10). The two full rims, the bridge and the two endpieces are integrally formed as a single piece, from a plastic. The two full rims (2, 4) are flexible, and are constituted by a closed, elastic band. The central piece of the full-rim frame is assembled into a central piece of a pair of eyeglasses with two lenses, whose outer circumferential lines have somewhat larger dimensions than the inner contour lines of the two full rims, so that the full rims of the central piece of the eyeglasses are stretched around the lenses, and their shape conforms to the shape of the lenses.

18. A method for making a central piece of a full rim frame with lenses for eyeglasses, wherein the central piece has a left full rim including an inner side and an end piece;
- a right full rim including an inner side and an end piece; and
a bridge for joining the left and right full rims, the method comprising;a) creating a left and a right eyeglass lens each having a peripheral contour shape selected from the group consisting of generally circular, generally rectangular, generally oval, and generally egg-like; and
a perimeter edge having a cross sectional profile selected from the group consisting of a semicircular protrusion, a semicircular groove, a triangular protrusion, and a triangular groove;
b) creating the central piece wherein the left and right full rims are flexible and each has a contour shape that is not identical to the peripheral contour shape of the respective left and right lenses, and the inner side of each full rim has a cross sectional profile complementary to the corresponding lens; and
c) inserting the left and right lenses into the respective left and right full rim whereby each rim elastically receives and retains the respective lens, thereby generally conforming to the peripheral contour shape of the respective lens. - View Dependent Claims (19, 20)
