Abstract
Abstract A system for attaching a replaceable, customizable nosepiece to an eyeglass frame is disclosed where the eyeglass and nosepiece fit together through a snappable attachment. The eyewires of the eyeglass frame are provided with a notch and adjacent projection. The nosepiece is roughly horseshoe shape, sized and shaped to fit between the eyewires under the connecting bridge of the frame. The tips of the horseshoe are shaped to snap into the notches on the eyewires, and be retained by the adjacent projections. In this manner, the nosepiece may be specifically selected for or customized to the particular size and shape of the user's nose.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
230 words
A system for attaching a nosepiece to an eyeglass frame to be worn by a user, comprising: an eyeglass frame having a pair of eyewires; a bridge connecting the eyewires, each eyewire having a notch and a contiguous projection located between the connecting bridge and the center point of the bottom half of the eyewire; a substantially horseshoe shaped nosepiece, having two arms, and an open end and a closed end, each of said arms including a pair of ridges with one of said ridges located along a forward edge of an outside surface of the arm and the other ridge of said pair of ridges being located along a rearward edge of an outside surface of the arm, said ridges of each pair of ridges being spaced apart a sufficient distance to engage the eyewire between said pair of ridges; the outside shape and size of the nosepiece being matched with the shape and size of the eyewires and bridge connecting the eyewires, such that the nosepiece may be snapped into place between the eyewires with a bottom surface of each of said arms resting on a top surface of said contiguous projection so that said nosepiece is retained by said notches and projections engaging said arms and so that said outside surface of each arm of said nosepiece abuts a portion of the eyewire adjacent the outside surface.
Claim 2
Independent Claim
230 words
A system for attaching a nosepiece to an eyeglass frame to be worn by a user, comprising: an eyeglass frame having a pair of eyewires; a bridge connecting the eyewires, each eyewire having a notch and a contiguous projection located between the connecting bridge and the center point of the bottom half of the eyewire; a substantially horseshoe shaped nosepiece, having two arms, and an open end and a closed end, each of said arms including a pair of ridges with one of said ridges located along a forward edge of an outside surface of the arm and the other ridge of said pair of ridges being located along a rearward edge of an outside surface of the arm, said ridges of each pair of ridges being spaced apart a sufficient distance to engage the eyewire between said pair of ridges; the outside shape and size of the nosepiece being matched with the shape and size of the eyewires and bridge connecting the eyewires, such that the nosepiece may be snapped into place between the eyewires with a bottom surface of each of said arms resting on a top surface of said contiguous projection so that said nosepiece is retained by said notches and projections engaging said arms and so that said outside surface of each arm of said nosepiece abuts a portion of the eyewire adjacent the outside surface.
Claim 3
Dependent Claim
20 words
The system of claim 1 where said nosepiece further comprises a bridge portion adjacent the closed end of the horseshoe.
Claim 4
Dependent Claim
