DETAILED DESCRIPTION OF THE INVENTION
The present invention may be embodied in various forms. An embodiment of eyewear 1 is shown in FIGS. 1 through 7. In certain embodiments, eyewear 1 is sunglasses. In particular, the embodiment depicted here illustrates performance sunglasses, commonly referred to as shield eyewear, which include a single lens and are often used by bicycle riders and runners. However, it is to be appreciated that eyewear 1 is meant to include all types of glasses, including glasses having two separate lenses. Other eyewear suitable for use includes, for example, prescription glasses and safety glasses with clear lenses.
Certain directional terms used herein refer to directions with respect to the wearer of eyewear 1. Thus, the terms outward, outwardly, forward, and forwardly, as used herein, refer to a surface facing away from, or a direction extending away from, the face of a wearer of eyewear 1. The terms inward, inwardly, rear, and rearwardly refer to a surface facing toward, or a direction extending toward, the face of a wearer of eyewear 1.
The eyewear 1 of the present invention includes at least a lens 2, a nosebridge 8, and a nosepad 12. Preferably, the lens 2 has a front surface 3, a rear surface 4, and a peripheral edge surface 5. The nosebridge 8 preferably has a first end 9, a second end 10, and a substantially inverted-U-shaped body 11. Preferably, the nosebridge 8 is releasably secured to said lens 2. The adjustable nosepad 12 preferably has a first end 13, a second end 14, and a substantially inverted-U-shaped body 15. Preferably, the nosepad 12 is releasably secured to the nosebridge 8. The nosepad 12 preferably comprises a core member 16 and an outer member 17. Preferably, the outer member 17 substantially encases the core member 16. The outer member 17 is preferably softer than the core member 16 in order to improve the grip and comfort of the nosepad 12 on the user's nose.
Preferably, the eyewear 1 of the present invention also includes a frame 20, to which an upper edge 21 of the lens 2 is secured, and a pair of temple arms 22 at opposed ends 23 of the frame 20. The temple arms 22 may be secured to the frame 20, or to both the frame 20 and the lens 2. The temple arms 22 may pivot with respect to the lens 2 and the frame 20, or they may be fixed with respect to the lens 2 and the frame 20.
The temple arms 22 and the frame 20 may be formed of any suitable material, including, for example, plastic, or a rubber-coated core material, such as metal or plastic. In certain embodiments, the temple arms 22 and the frame 20 may be formed of a flexible, resilient material, such as beta titanium. In other embodiments, the temple arms 22 and frame 20 may be formed of a rigid material, such as a fiber-reinforced material, for example a carbon-fiber composite. Other suitable materials for the temple arms 22 and frame 20 will become readily apparent to those skilled in the art, given the benefit of this disclosure.
