Abstract
Abstract A glare shield assembly for mounting on a sun visor of a motor vehicle. A light-filtering shield is mounted in offset relationship to and on a pair of spaced pivots attached to and below the lower edge of the sun visor. The offset pivot makes it possible to position the shield as a lower extension of the visor either by pivoting the shield forwardly of the visor or rearwardly of the visor. Further, the pivot is located closer to one of the horizontal edges of the sheild than to the opposite horizontal edge of the shield so that in one of its positions more of the shield projects below the visor than in the other of its positions. In addition, an area of the shield has different filtering characteristics on one side of its pivot than on the other side of its pivot for selectively to overcome different glare conditions.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
116 words
A glare shield device for an operator of a motor vehicle comprising: visor means mountable behind the windshield of a motor vehicle and having opposite sides and a lower end portion, clamping means for gripping on said opposite sides of said lower end portion of said visor means and extending beyond said lower end portion, pivot means supported and frictionally gripped by said clamping means beyond said lower end portion, said clamping means normally and yieldably holding said pivot means against rotation, and a glare shield having a broadside surface, said shield affixed on said broadside thereof to said pivot means in spaced relationship thereto, for selective positioning on either side of said lower end portion.
Claim 2
Dependent Claim
116 words
A glare shield device for an operator of a motor vehicle comprising: visor means mountable behind the windshield of a motor vehicle and having opposite sides and a lower end portion, clamping means for gripping on said opposite sides of said lower end portion of said visor means and extending beyond said lower end portion, pivot means supported and frictionally gripped by said clamping means beyond said lower end portion, said clamping means normally and yieldably holding said pivot means against rotation, and a glare shield having a broadside surface, said shield affixed on said broadside thereof to said pivot means in spaced relationship thereto, for selective positioning on either side of said lower end portion.
Claim 3
Dependent Claim
176 words
A glare shield device for mounting on a visor by an operator of a motor vehicle comprising: a substantially flat transparent member having two spaced broadside surfaces defined by two spaced apart elongated edges, at least one cylindrical pivoting member mounted on and spaced from one of said broadside surfaces of said transparent member, said pivot member having its elongated axis substantially parallel to one of said elongated edges of said transparent member, a pair of elongated opposed clamping members, each having one end having a cylindrical concave bearing surface for overlying and bearing on a portion of the cylindrical surface of said pivot member and the other end of each of said elongated clamping members having a smooth raised gripping surface with an aperture centrally located therein, and a toggle link interconnecting said clamping Members at a point intermediate its ends, said link securing said concave bearing surfaces in a clamping relationship around said pivot member and said opposed raised gripping surfaces in a pinching relationship on opposite sides of the visor of the vehicle.
Claim 4
Dependent Claim
176 words
A glare shield device for mounting on a visor by an operator of a motor vehicle comprising: a substantially flat transparent member having two spaced broadside surfaces defined by two spaced apart elongated edges, at least one cylindrical pivoting member mounted on and spaced from one of said broadside surfaces of said transparent member, said pivot member having its elongated axis substantially parallel to one of said elongated edges of said transparent member, a pair of elongated opposed clamping members, each having one end having a cylindrical concave bearing surface for overlying and bearing on a portion of the cylindrical surface of said pivot member and the other end of each of said elongated clamping members having a smooth raised gripping surface with an aperture centrally located therein, and a toggle link interconnecting said clamping Members at a point intermediate its ends, said link securing said concave bearing surfaces in a clamping relationship around said pivot member and said opposed raised gripping surfaces in a pinching relationship on opposite sides of the visor of the vehicle.
Claim 5
Dependent Claim
44 words
A glare shield device as defined by claim 2 wherein the distance from the axis of said pivot member to one elongated edge of said transparent member is greater than the distance from said axis to the other elongated edge of said transparent member.
Claim 6
Dependent Claim
21 words
A glare shield device as defined by claim 2 wherein said transparent member is a filter to the rays of sunlight.
Claim 7
Dependent Claim
54 words
A glare shield device as defined by claim 2 additionally including a second cylindrical pivot member, a second pair of elongated clamping members and a second toggle link, said second pivot member having its axis substantially in line with said first cylindrical pivot member and spaced therefrom in the direction of said elongated edge.
Claim 8
Dependent Claim
38 words
A glare shield device as defined by claim 2 wherein said raised gripping surface of said elongated clamping member has a cylindrical shape with an elongated aperture transverse to the direction of length of said elongated clamping member.
Claim 9
Dependent Claim
31 words
A glare shield device as defined by claim 2 wherein said toggle link is a threaded member mounted for controlling the clamping forces between opposed cylindrical surfaces of said clamping members.
Claim 10
Dependent Claim
33 words
A glare shield device as defined by claim 2 wherein said toggle link is positioned closer to said concave bearing surfaces then said convex gripping surfaces of said pair of opposed clamping members.
Claim 11
Dependent Claim
61 words
Ag glare shield device as defined by claim 2 wherein the axis of said cylindrical pivot member is spaced from said broadside surface of said transparent member a distance equal to substantially one half the thickness of the vehicle visor and said pivot member is spaced from the edge of the visor for selective positioning on either side of the visor.
