Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
141 words
An illuminated gunsight comprising an electrically powered, light emitter with a low electrical drain ranging from 1 to 75 milliamps; means for supporting said light emitter on a gun barrel with said supporting means comprising an elongated, generally cylindrical flexible half shell adapted to fit on the upper portion of a gun barrel, said half shell having an upper surface with an outward protrusion on said upper surface, and said protrusion having a recess therein into which said light emitter is fixedly placed, with said protrusion thereby forming a sighting member; means for positioning said supporting means so that said light emitter is centered on said gun barrel; means for removeably mounting said supporting means on said gun barrel; and an electrical power source for said light emitter with an electrical connection therebetween, said electrical connection having an electrical switching element.
Claim 2
Dependent Claim
141 words
An illuminated gunsight comprising an electrically powered, light emitter with a low electrical drain ranging from 1 to 75 milliamps; means for supporting said light emitter on a gun barrel with said supporting means comprising an elongated, generally cylindrical flexible half shell adapted to fit on the upper portion of a gun barrel, said half shell having an upper surface with an outward protrusion on said upper surface, and said protrusion having a recess therein into which said light emitter is fixedly placed, with said protrusion thereby forming a sighting member; means for positioning said supporting means so that said light emitter is centered on said gun barrel; means for removeably mounting said supporting means on said gun barrel; and an electrical power source for said light emitter with an electrical connection therebetween, said electrical connection having an electrical switching element.
Claim 3
Dependent Claim
19 words
An illuminated gun sight as in claim 1 wherein said low drain light emitter is a light emitting diode.
Claim 4
Dependent Claim
23 words
An illuminated gun sight as in claim 1 wherein said cylindrical half shell has a planar surface with said protrusion upon said surface.
Claim 5
Dependent Claim
16 words
An illuminated gun sight as in claim 3 wherein said planar surface has a non-glare finish.
Claim 6
Dependent Claim
26 words
An illuminated gun sight as in claim 1 wherein said recess is of a depth such that said light emitter is fully recessed within said recess.
Claim 7
Dependent Claim
28 words
An illuminated gun sight as in claim 1 wherein said centering means comprises an aperture in said supporting means to accomodate the existing sight of said gun barrel.
Claim 8
Dependent Claim
44 words
An illuminated gun sight as in claim 1 wherein said means for removeably mounting comprises one or more straps separably connected to said supporting means with said connection peripherally enclosing said gun barrel within a space defined by said straps and said supporting means.
Claim 9
Dependent Claim
32 words
An illuminated gun sight as in claim 1 wherein said power source comprises one or more electrical cells, said cells being contained within a casing which is integral with said supporting means.
Claim 10
Dependent Claim
19 words
An illuminated gun sight as in claim 1 wherein said electrical connection includes at least 2 metallic contact strips.
Claim 11
Dependent Claim
31 words
An illuminated gun sight as in claim 9 wherein said electrical switching element is a metallic screw with the end of said screw being adapted to span and contact said strips.
