Adjustable cover for use with fiber optic band mounted atop an advanced combat optical gunsight in order to adjust intensity of illuminated reticle

Abstract

An attachable and length adjustable cover for use with a fiber optic light receptor band associated with an optical gunsight for varying an amount of light which is permitted to enter the fiber optic of the rifle scope and be communicated to the associated reticle display. A body overlays the fiber optic band and includes a plurality of telescopically adjustable sections which overlays at least a corresponding portion of the optic band and which is movable in at least one direction to vary an exposed portion of the band which is available for collecting ambient light.

1 . An attachable and length adjustable cover for use with a fiber optic light receptor band associated with an optical gunsight for varying an amount of light which is permitted to enter the fiber optic of the rifle scope and be communicated to the associated reticle display, comprising:
 said cover comprising a body overlaying the fiber optic band, said body having at least one section which overlays the optic band and which is movable in at least one direction to vary an exposed portion of the band which is available for collecting ambient light.   
     
     
         2 . The cover as described in  claim 1 , further comprising a plurality of individual and telescoping shade portions. 
     
     
         3 . The cover as described in  claim 2 , said telescoping portions each further comprising at least one of an opaque or selectively light transmitting composition. 
     
     
         4 . The cover as described in  2 , each of said telescoping portions exhibiting, in cross section, an arcuate configuration closely dimensioned to overlay the fiber optic band. 
     
     
         5 . The cover as described in  claim 2 , further comprising a grasping tab extending from an outermost end of an end-extendable shade portion and facilitating a desired degree of shade covering over the fiber optic band. 
     
     
         6 . The cover as described in  claim 2 , further comprising an elongated and one piece clip on design containing said plurality of telescoping shade portions, said body including at least one of side and end positioned tabs for facilitating engagement to corresponding locations on the gunsight. 
     
     
         7 . The cover as described in  claim 6 , said clip further comprising inner engagement tabs biasing against outer corresponding edges of upper ears of the gunsight and between which is seated the fiber optic band. 
     
     
         8 . The cover as described in  claim 1 , further comprising a thin filament skirt integrally extending from said body and which is adapted to being sandwiched underneath an adjustor knob cap associated with the optical gunsight. 
     
     
         9 . The cover as described in  claim 1 , further comprising an arcuate contoured covering shield with end rotatable thumb screw supported within said body and being selectively actuated to reveal varying amounts of the underside located fiber optic band. 
     
     
         10 . The cover as described in  claim 1 , further comprising an LED element built into a location associated with said body for assisting in illuminating the fiber optic band, a power component in communication with the LED element. 
     
     
         11 . The cover as described in  claim 10 , said power component adapted to securing to a side location of the optical gunsight, a cable or line communicating the power component to the LED element. 
     
     
         12 . The cover as described in  claim 10 , further comprising a power supply including a battery activated upon a user triggering an on/off button in order to illuminate the LED for providing any desired degree of artificial light input to the fiber optic band. 
     
     
         13 . The cover as described in  claim 10 , said power supplying component being integrally formed with an extending side location of the body such that it optionally may, but need not, be separately secured to the proximate side surface of the optical gunsight. 
     
     
         14 . An attachable and length adjustable cover for use with a fiber optic light receptor band associated with an optical gunsight for varying an amount of light which is permitted to enter the fiber optic of the rifle scope and be communicated to the associated reticle display, comprising:
 said cover comprising a body overlaying the fiber optic band, said body having a plurality of individual and telescoping shade portions which overlay the optic band and which are inter-movable in at least one direction to vary an exposed portion of the band available for collecting ambient light; and   an elongated and one piece clip on design containing said plurality of telescoping shade portions, said body including at least one of side and end positioned tabs for facilitating engagement to corresponding locations on the gunsight.   
     
     
         15 . The cover as described in  claim 14 , said telescoping portions each further comprising at least one of an opaque or selectively light transmitting composition. 
     
     
         16 . The cover as described in  14 , each of said telescoping portions exhibiting, in cross section, an arcuate configuration closely dimensioned to overlay the fiber optic band. 
     
     
         17 . The cover as described in  claim 14 , further comprising a grasping tab extending from an outermost end of an end-extendable shade portion and facilitating a desired degree of shade covering over the fiber optic band. 
     
     
         18 . An attachable and length adjustable cover for use with a fiber optic light receptor band associated with an optical gunsight for varying an amount of light which is permitted to enter the fiber optic of the rifle scope and be communicated to the associated reticle display, comprising:
 said cover comprising a body overlaying the fiber optic band, said body having at least one section which overlays the optic band and which is movable in at least one direction to vary an exposed portion of the band which is available for collecting ambient light; and   a thin filament skirt integrally extending from said body and which is adapted to being sandwiched underneath an adjustor knob cap associated with the optical gunsight   
     
     
         19 . The cover as described in  claim 18 , further comprising an arcuate contoured covering shield with end rotatable thumb screw supported within said body and being selectively actuated to reveal varying amounts of the underside located fiber optic band. 
     
     
         20 . The cover as described in  claim 18 , further comprising an LED element built into a location associated with said body for assisting in illuminating the fiber optic band, a power component in communication with the LED element.
