ABSTRACT:
A clamp assembly comprises a clamp (12) having two levers (1, 2) linked at middle areas thereof with first ends thereof closing together to form clamping jaws (5, 6) and second, opposite, ends thereof formed as opening grips (3, 4) for separating the clamping jaws, which are spring loaded toward one another. The clamping jaws (5, 6) have forked shapes. The branches of the forks, and the ends thereof, are arranged to be spaced from one another so that they extend across, or extend over, a bridge of a pair of eyeglasses to be placed on inner, upper edges of spectacle glasses (13) or on an eyeglass frame (14). A first lever (2) of the clamp (12) has thereon a clamp coupling element (10, 19, 22, 24) for being selectively attached to, and selectively detached from, an optical-device coupling element (18, 20, 23, 25) on an optical device. The clamp assembly makes possible an easy and quick exchange of optical devices to be attached thereto.
