Lighted gun sights

Abstract

Apparatus for assisting aiming of firearms in darkness comprising a sight defining two spaced upstanding elements, each bearing at identical levels thereon one of a pair of light sources defining dots; a forward pointer comprising a base portion whose height is determined by rotatable threading thereof into a socket fixed on the firearm, and a top portion which is rotatably mounted with respect to the base portion for rotation about the longitudinal axis of the pointer; and a third light source defining a dot associated with the top portion of the forward pointer of the firearm, the third light source arranged to be aligned along a line between the pair of light sources and aligned with a target when the firearm is aimed in darkness.

I claim: 
     
       1. Apparatus for assisting aiming of firearms in darkness comprising: .[.a sight defining two spaced upstanding elements, each bearing at identical levels thereon one of a pair of light sources defining dots;.].   a .[.forward.]. pointer having a longitudinal axis, said pointer comprising a base portion whose height is determined by rotatable threading thereof into a socket fixed on the firearm, and a top portion which is rotatably mounted with respect to said base portion and arranged for rotation about a rotation axis defined by the longitudinal axis of said .[.forward.]. pointer without changing the height thereof; and a .[.third.]. light source defining a dot associated with the top portion of said .[.forward.]. pointer of said firearm, .[.said third light source arranged to be aligned along a line between said pair of light sources and aligned with a target when the firearm is aimed in darkness,.]. whereby said .[.third.]. light source may be maintained in a rearward facing direction with respect to the firearm at any height .[.thereof.]. .Iadd.of the light source. .Iaddend.   
     
     
       2. Apparatus according to claim 1 and wherein .[.at least one of.]. said light .[.sources.]. .Iadd.source .Iaddend.comprises luminescent material. 
     
     
       3. Apparatus according to claim 1 and being formed of a plastic material. 
     
     
       4. Apparatus according to claim 1 and being formed of metal. 
     
     
       5. Apparatus according to claim 8 and wherein said sight further comprises a plate member disposed between said upstanding elements and defining a recess disposed along a line with the pair of light sources disposed on two upstanding elements. 
     
     
       6. Apparatus according to claim 8 and wherein each of said pair of light sources defines an imaginary illuminated circle of a first color on said sight. 
     
     
       7. Apparatus according to claim 6 and wherein said .[.third.]. light source .[.comprises.]. .Iadd.on said pointer comprises .Iaddend.a light source of a second color associated with said forward pointer of the firearm. .Iadd.8. Apparatus according to claim 1 and also comprising a sight defining two spaced upstanding elements, each bearing at identical levels thereon one of a pair of light sources defining dots and wherein said light source on said pointer is arranged to be aligned along a line between said pair of light sources and aligned with a target when a firearm is aimed in darkness. .Iaddend.
