Abstract A one-piece plastic nosepiece for metal eyeglass frames together with an improved manner of attaching the nosepiece to the frames. A groove extending across substantially the entire width of the arched portion of the nosepiece is mated with a lip defining member associated with the bridge member of the frames and then locked into position by a pair of vertical screws extending through both the lip and the nosepiece. This manner of attachment provides a sturdy product that can effectively withstand rough treatment without breaking or moving out of adjustment. In addition, because the nosepiece can be securely attached to the frames along its upper arched portion, its depending side portions need not be attached to the frames and can be left ''''floating'''' behind the eye wires. Accordingly, by making the nosepiece from a heat softenable thermoplastic material, it becomes possible to soften and then adjust the shape of the nosepiece while on the frames so as to properly fit a particular wearer. This adjustment capability, together with the inherent resiliency of the floating side portions, reduces the number of nosepiece sizes and shapes that must be manufactured, and, hence, provides a more marketable product.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
223 words
A metal eyeglass frame comprising, in combination: a. a pair of lens receiving portions; b. a bridge member connecting said lens receiving portions; c. a nosepiece, said nosepiece comprising a single piece of plastic material and including an upper arched portion adapted to engage the upper part of the nose of a wearer and a pair of side portions depending from said arched portion and adapted to engage the sides of the nose of said wearer; and d. means for rigidly coupling said nosepiece to said bridge member, said coupling means including: i. means for interlocking the arched portion of said nosepiece to said bridge member, said interlocking means including means for defining a lip extending substantially across the width of one of said bridge member and arched portion and means for defining a groove extending substantially across the width of the other of said bridge member and said arched portion for mating with said lip; and ii. fastening means for rigidly fastening said nosepiece and bridge member together in said interlocked condition e. said means for defining a lip comprises a metal bar extending substantially across the width of said bridge member and protruding therefrom; and f. said means for defining a groove extending substantially across the width of said arched portion of said nose piece for mating with said metal bar.
Claim 2
Dependent Claim
223 words
A metal eyeglass frame comprising, in combination: a. a pair of lens receiving portions; b. a bridge member connecting said lens receiving portions; c. a nosepiece, said nosepiece comprising a single piece of plastic material and including an upper arched portion adapted to engage the upper part of the nose of a wearer and a pair of side portions depending from said arched portion and adapted to engage the sides of the nose of said wearer; and d. means for rigidly coupling said nosepiece to said bridge member, said coupling means including: i. means for interlocking the arched portion of said nosepiece to said bridge member, said interlocking means including means for defining a lip extending substantially across the width of one of said bridge member and arched portion and means for defining a groove extending substantially across the width of the other of said bridge member and said arched portion for mating with said lip; and ii. fastening means for rigidly fastening said nosepiece and bridge member together in said interlocked condition e. said means for defining a lip comprises a metal bar extending substantially across the width of said bridge member and protruding therefrom; and f. said means for defining a groove extending substantially across the width of said arched portion of said nose piece for mating with said metal bar.
Claim 3
Dependent Claim
69 words
A metal eyeglass frame as recited in claim 1 wherein said fastening means includes: a. a first pair of substantially vertical apertures extending through said arched portion of said nosepiece; b. a second pair of substantially vertical apertures extending through said metal bar in alignment with said apertures in said arched portion; and c. a pair of screws extending through said apertures for fastening said nosepiece to said bridge.
Claim 4
Dependent Claim
32 words
A metal eyeglass frame as recited in claim 2 wherein said first pair of apertures are countersunk such that said pair of screws are substantially embedded within said apertures without protruding therefrom.
Claim 5
Dependent Claim
45 words
A metal eyeglass frame as recited in claim 1 wherein said side portions float freely adjacent the lens receiving portions of said frame whereby the inherent resiliency of said side portions allow them to better conform to the nose of the wearer of said frames.
Claim 6
Dependent Claim
38 words
A metal eyeglass frame as recited in claim 1 wherein said nosepiece is formed of a heat softenable thermoplastic material capable of being slightly deformed when heated for adjustment to the nose of the wearer of said frames.
