ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATIONS
Not Applicable.
STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
Not Applicable.
The present invention relates in general to eye covering, and more particularly concerns novel eyeglasses especially useful in connection with comfortably affording eye protection.
BACKGROUND OF THE INVENTION
For background, reference is made to U.S. Pat. No. 5,457,505, which describes eyewear construction. Reference is also made to commercially available sport glasses such as Nike sport glasses that include some structure made by a two-shot process in a single mold.
BRIEF SUMMARY OF THE INVENTION
According to the invention, there is a unitary structure made by a two-shot process in a single mold having an outer hard portion chemically bonded to an inner soft portion formed with a brow portion adapted to softly engage the brow of a wearer, a nose portion adapted to softly engage the nose of a wearer, with brow and nose portions of hard material adapted to engage temple frame pieces. The brow hard portions are adapted to engage hard material ratchet adjustment pieces as well as a transparent lens structure adapted to cover the eyes of a wearer. The eyeglasses according to the invention include the lens portion seated in the hard brow portion and the temple pieces seated in the hard end portions of the brow portion. A feature of the invention is forming the nose piece with flexible fingers for comfortably engaging the nose of a wearer while maintaining the eyeglasses in a stable position on the nose of the wearer, the length of each finger being significantly shorter than the length of each length of the nose piece with the spacing between fingers corresponding substantially to the thickness of the fingers and the length of the fingers progressively decreasing from the center to each end of each nose piece leg. The fingers provide an adjustment feature by bending to correspond to the size and shape of various noses.
It is an important object of the invention to provide improved eye covering structure.
Additionally, the soft material is intended to provide a shock-absorbing feature for the face.
Other features, object and advantages of the invention will become apparent from the following detailed description when read in connection with the accompanying drawings in which:
