Abstract
Abstract A sighting device of the reflex or infinity type which is nonmagnifying and which provides a collimated reticle image superimposed on the field of view. The reticle is a compound member having a first part illuminated by surrounding ambient light and a second part illuminated by down range ambient light. Both reticle parts appear to the viewer as colored aiming indicia images.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
219 words
A reflex sighting device for use with a projectile launcher, said device comprising: a. a tubular housing having an objective end and an ocular end; b. highly reflective means mounted in said housing to provide a reflecting surface facing said objective end of said housing, said reflecting surface being configured to provide first reticle indicia for said device which first reticle indicia is illuminated by down range ambient light; c. means mounted in said housing to provide second reticle indicia illuminated by surrounding ambient light; d. fluorescent means mounted on said housing between the ocular and objective ends thereof and adjacent said second reticle indicia and operable to absorb surrounding ambient light, fluoresce the absorbed light and transmit the fluoresced light to said second reticle indicia to illuminate the latter; e. dichroic partially reflecting means mounted in said housing between said first and second reticle indicia and said objective end of said housing, said reflecting means being operable to transmit downrange ambient light to said reflecting surface, and further operable to reflect images of said first and second reticle indicia toward said ocular end of said housing substantially along the axis of said housing; and f. means in said housing focussed on said first and second reticle indicia to provide collimated images of said first and second reticle indicia.
Claim 2
Dependent Claim
219 words
A reflex sighting device for use with a projectile launcher, said device comprising: a. a tubular housing having an objective end and an ocular end; b. highly reflective means mounted in said housing to provide a reflecting surface facing said objective end of said housing, said reflecting surface being configured to provide first reticle indicia for said device which first reticle indicia is illuminated by down range ambient light; c. means mounted in said housing to provide second reticle indicia illuminated by surrounding ambient light; d. fluorescent means mounted on said housing between the ocular and objective ends thereof and adjacent said second reticle indicia and operable to absorb surrounding ambient light, fluoresce the absorbed light and transmit the fluoresced light to said second reticle indicia to illuminate the latter; e. dichroic partially reflecting means mounted in said housing between said first and second reticle indicia and said objective end of said housing, said reflecting means being operable to transmit downrange ambient light to said reflecting surface, and further operable to reflect images of said first and second reticle indicia toward said ocular end of said housing substantially along the axis of said housing; and f. means in said housing focussed on said first and second reticle indicia to provide collimated images of said first and second reticle indicia.
Claim 3
Dependent Claim
20 words
The device of claim 1, further comprising means in the interior of said housing for rendering the latter substantially non-reflective.
Claim 4
Dependent Claim
25 words
The device of claim 1, wherein said first and second reticle indicia are configured so as to provide said device with a common aiming point.
Claim 5
Dependent Claim
28 words
The device of claim 3, wherein said first reticle indicia is a ring and said second reticle indicia is a spot contained within and coaxial with said ring.
Claim 6
Dependent Claim
88 words
The device of claim 1, further comprising a window in said tubular housing, and a pod of opaque material mounted in said housing adjacent said window, said pod having one end wall facing said objective end of said housing, with said end wall being tilted with respect to the axis of said housing, said fluorescent means being contained within said pod, said reflective surface being positioned on said end wall of said pod, and said second reticle indicia being an opening in said end wall of said pod.
Claim 7
Dependent Claim
20 words
The device of claim 5, further comprising means for rendering said pod substantially non-reflective except for said reflective surface thereon.
