US 5,495,676 A · Lens cap assembly and removal method

Abstract

A lens apparatus is disclosed for use with a firearm scope. The lens apparatus includes first and second polarized lenses that move relative to each other. When differently colored lens materials are used and when moved relative to each other, the color seen through the two polarized lenses changes. In affixing the first and second polarized lenses to the firearm scope, first and second connection assemblies are utilized. The two connection assemblies have first and second latch release members, respectively. The two latch release members are located on the right and left sides of a scope when a user is in the normal shooting position. Upon actuation of the latch release member, pivotal movement of the polarized lenses, relative to the firearm scope lenses occurs. Each of the two connection assemblies includes a sleeve member and a cap lid. The sleeve member is flexible to surround portions of the firearm scope and is made of a material different from the cap lid material. Each of the two connection assemblies also have a spring positioned in a lid hinge member. Each of the springs biases a polarized lens away from a firearm scope lens.

Dependent claims

A method for using polarized lenses with a firearm scope, comprising:

providing a firearm scope having a first scope lens and a second scope lens with a firearm scope body defined therebetween, said second scope lens being located more adjacent to a free end of a barrel of the firearm than said first scope lens;
connecting a first lid assembly having a rotatable first polarized lens with a center to said first scope lens;
mounting a second lid assembly having a rotatable second polarized lens with a center to said second scope lens;
rotating said first polarized lens in a first direction about an axis through said center thereof relative to said second polarized lens while a shooter is viewing through said first polarized lens and said first scope lens wherein cross-polarization is effected in which light, that is allowed to pass through said first and second polarized lenses, changes;
and
rotating said first polarized lens in a second direction about said axis, opposite said first direction, relative to said first polarized lens while the shooter is viewing through said first polarized lens and said first scope lens wherein cross-polarization is effected in which light, that is allowed to pass through said first and second polarized lenses, changes.
