说明书全文 | This application claims priority to and the benefit of U.S. Provisional Patent Application No. 60/660,482 filed on Mar. 8, 2005, the entire content of which is incorporated herein by reference. 1. Field of the Invention The present invention is in the field of eyewear design. 2. Description of the Related Art Rimless eyeglasses are well known in the art. Examples of such designs are shown in U.S. Pat. Nos. 6,896,367, 6,860,597, 6,827,439, and 6,793,338. The present invention, however, includes a unique bridge design that is structurally sound and attractive. The present invention is for a novel eyewear design. Utilization of the invention permits construction of rimless glasses that are structurally sound and attractive. In the preferred embodiment, the invention is a bridge structure for rimless glasses that includes a rear bridge portion, a front bridge portion; and fastening means for fastening the rear bridge portion to the front bridge portion. Preferably, the rear bridge portion comprises plastic and the front bridge portion comprises metal. Titanium is one metal that can be utilized. The fastening means can also be constructed to fasten nose pads to the bridge structure. The typical fastening means includes screws and screw receptors, with the screw receptors residing on the front bridge portion. Usually, the rear bridge portion is shaped to match the form of the front bridge portion and the front bridge portion fits over the rear bridge portion. The text, figures and photographs of U.S. Provisional Patent Application No. 60/660,482 filed on Mar. 8, 2005, are hereby incorporated in full by this reference. Also included in the bridge assembly are four screws (items 3-6) and two nose pads (7 and 8). Screws 3 and 4 extend through nose pad 7 and screws 5 and 6 extend through nose pad 8. Note that the front bridge portion includes four receptors for the screws. Fastening means other than screws, such as bolts and pins, can be utilized. Also, there can be less or more than four screws (or other fasteners). For example, only two screws might be used for the assembly. Also, the invention can be configured such that not all of the fasteners engage the nose pads. For example, two screws might be used on each side, with only one screw engaging the associated nose pad. It is preferred that the form of the rear bridge portion is shaped to match the form of the front bridge portion. In the preferred embodiment, the front bridge portion fits over the rear bridge portion. Thus, although the present invention has been described in detail with regard to the exemplary embodiments thereof and accompanying drawings, it should be apparent to those skilled in the art that various adaptations and modifications of the present invention may be accomplished without departing from the spirit and the scope of the invention. Accordingly, the invention is not limited to the precise embodiments shown in the drawings and described above. Rather, it is intended that all such variations not departing from the spirit of the invention be considered as within the scope thereof as limited solely by the claims appended hereto. |
