Abstract
Abstract A one-piece front is stamped out of aluminum material with a central bridge portion interconnecting a pair of lens rim portions having inner-peripheral grooves for receiving beveled edge lenses. The bridge portion is split by a longitudinally extending narrow gap between upper and lower bridge segments to facilitate insertion of the lenses, retention of the lense therein being effected by mechanical fastening means associated with the bridge segments. One of the bridge segments is vertically split to allow insertion and retention of each lense independent from the other. A combination nose pad mounting and bridge masking means is of a weldable material and has a plate portion overlying and concealing the bridge gap and split and has a pair of nose pads welded via associated nose pad arms thereto. A tang extending laterally of the masking plate is received within a slot formed in the bridge segments in marginal areas adjacent said gap and said mechanical fastening means passes through said tang to hold the construction in assembled relation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
143 words
In an eyeglasses frame construction having a one-piece front stamped out of aluminum with a central bridge portion interconnecting a pair of lens rim portions, the improvement comprising the provision of: bridge means defining a longitudinal gap extending completely across and completely through said bridge portion dividing it into upper and lower segments thereof to facilitate manipulation of said front for insertion of eyeglass lenses within said rim portions; a bridge plate of weldable material overlying said bridge portion and concealing said gap, said plate having a pair of opposed nose pads mounted thereto by pad arms welded to said plate; and means for holding said plate to said bridge portion with said nose pads positioned below said bridge portion, said holding means also holding said upper and lower segments together for closing said gap for retaining said lenses within said rim portions.
Claim 2
Dependent Claim
143 words
In an eyeglasses frame construction having a one-piece front stamped out of aluminum with a central bridge portion interconnecting a pair of lens rim portions, the improvement comprising the provision of: bridge means defining a longitudinal gap extending completely across and completely through said bridge portion dividing it into upper and lower segments thereof to facilitate manipulation of said front for insertion of eyeglass lenses within said rim portions; a bridge plate of weldable material overlying said bridge portion and concealing said gap, said plate having a pair of opposed nose pads mounted thereto by pad arms welded to said plate; and means for holding said plate to said bridge portion with said nose pads positioned below said bridge portion, said holding means also holding said upper and lower segments together for closing said gap for retaining said lenses within said rim portions.
Claim 3
Dependent Claim
37 words
The improvement in eyeglasses frame construction of claim 1 wherein: said lower bridge segment is divided into independently movable left and right hand portions to facilitate independent retention of each of said lenses within said rim portions.
Claim 4
Dependent Claim
38 words
The improvement in eyeglasses frame construction of claim 1 wherein: said bridge plate includes a body portion overlying the forward surfaces of said bridge segments and a top flange overlying the top surface of said upper bridge segment.
Claim 5
Dependent Claim
92 words
The improvement in eyeglasses frame construction of claim 1 wherein: said bridge plate is provided with laterally extending tang means for extending into said gap between said upper and lower bridge segments for positioning said plate on said bridge portion, said tang means is provided with an aperture therethrough within said bridge portion, said bridge portion is provided with a vertical bore therethrough, said tang aperture being aligned with said bore, and said means for holding said plate to said bridge includes a fastening member lying within said bore through said aperture.
Claim 6
Dependent Claim
71 words
The improvement in eyeglasses frame construction of claim 4 wherein: said upper and lower bridge segments are provided with a pair of opposed slot-like recesses in marginal areas thereof adjacent said gap for receiving said tang means for positioning said tang means and plate relative to said front and for allowing said gap to be narrowed upon tightening of said holding means to retain said lenses within said front rim portions.
Claim 7
Dependent Claim
106 words
An eyeglasses construction comprising: a one-piece front including a central bridge portion interconnecting a pair of lens rim portions; bridge means defining a gap completely through and extending completely across said bridge portion to facilitate the insertion of eyeglasses lenses into said lens rim portions; a bridge face plate overlying said bridge portion and concealing said gap, said face plate having tang means extending laterally into said gap for mounting and positioning said plate in said bridge portion; and fastening means extending through said bridge and tang behind said plate for narrrowing said gap and holding said plate and lenses in assembled relation to said front.
Claim 8
Dependent Claim
106 words
An eyeglasses construction comprising: a one-piece front including a central bridge portion interconnecting a pair of lens rim portions; bridge means defining a gap completely through and extending completely across said bridge portion to facilitate the insertion of eyeglasses lenses into said lens rim portions; a bridge face plate overlying said bridge portion and concealing said gap, said face plate having tang means extending laterally into said gap for mounting and positioning said plate in said bridge portion; and fastening means extending through said bridge and tang behind said plate for narrrowing said gap and holding said plate and lenses in assembled relation to said front.
Claim 9
Dependent Claim
153 words
In an eyeglasses frame construction having a one-piece front formed out of a material which is not readily bonded to other materials by welding and includes a bridge portion interconnecting a pair of lens receiving rim portions, the improvement comprising the provision of: a nose pad mounting means for mounting a pair of nose pads in spaced apart, opposed position suitable for resting upon the nose of a user of said construction; and mechanical means extending through said mounting means and at lEast a part of said bridge portion for connecting said nose pad mounting means to said front by a mechanical interconnection between said front and said nose pad mounting means said bridge portion is split generally horizontally into two segments thereof to facilitate insertion of lenses into said rim portions, and said nose pad mounting means includes a masking plate for overlying and concealing said bridge portion where it is split.
Claim 10
Dependent Claim
153 words
In an eyeglasses frame construction having a one-piece front formed out of a material which is not readily bonded to other materials by welding and includes a bridge portion interconnecting a pair of lens receiving rim portions, the improvement comprising the provision of: a nose pad mounting means for mounting a pair of nose pads in spaced apart, opposed position suitable for resting upon the nose of a user of said construction; and mechanical means extending through said mounting means and at lEast a part of said bridge portion for connecting said nose pad mounting means to said front by a mechanical interconnection between said front and said nose pad mounting means said bridge portion is split generally horizontally into two segments thereof to facilitate insertion of lenses into said rim portions, and said nose pad mounting means includes a masking plate for overlying and concealing said bridge portion where it is split.
Claim 11
Dependent Claim
43 words
The improvement in eyeglasses frame construction of claim 7 wherein: said masking plate includes a laterally extending protrusion positioned between said two segments where said bridge portion is split, and said mechanical means includes means for holding said protrusion between said two segments.
