Abstract

A reflex sight for a firearm has an optical element received within a receptacle of a housing. The housing is mounted on the firearm. Shoulders extending from a base of the optical element engage corresponding shoulders extending from the housing into the receptacle to position the optical element so that it intersects a line of sight parallel to but offset from the firing axis of the firearm. The optical element includes a collimating reflector which produces a virtual reticle visible when viewed along the line of sight when aiming the firearm. The optical element is captured within the receptacle between the firearm or a plate and the shoulders of the housing.

First claim

What is claimed is:

1. A reflex sight for a firearm having a firing axis, said reflex sight comprising:
a housing mountable on said firearm, said housing defining a line of sight parallel to said firing axis;
a receptacle positioned within said housing underlying said line of sight;
an optical element comprising a reflector attached to a base, said base being received within said receptacle such that said reflector intersects said line of sight; wherein
said housing comprises a first shoulder projecting transversely to a plane of said reflector within said receptacle; and
said base comprises a second shoulder projecting transversely to said plane of said reflector, said first and second shoulders engaging one another when said optical element is positioned within said receptacle.

2. The reflex sight according to claim 1 , wherein said optical element is removable from said receptacle.

3. The reflex sight according to claim 1 , wherein said optical element is adjustably positionable relatively to said line of sight.

4. The reflex sight according to claim 1 , further comprising a hood mounted on said housing, said hood surrounding at least a portion of said reflector.

5. The reflex sight according to claim 1 , wherein said housing further comprises a bottom plate covering at least a portion of an opening providing access to said receptacle.

6. The reflex sight according to claim 1 , wherein said reflector has indicia on a surface thereof.

7. The reflex sight according to claim 6 , wherein said indicia comprise a sight reticle.

8. The reflex sight according to claim 7 , wherein said sight reticle simulates a notch sight.

9. The reflex sight according to claim 1 , wherein said reflector comprises a collimating mirror.

10. The reflex sight according to claim 1 , further comprising a projector located within said housing, said projector projecting an image onto said reflector.

11. The reflex sight according to claim 10 , wherein said image comprises a virtual reticle.

12. The reflex sight according to claim 11 , wherein said virtual reticle comprises a dot.

13. The reflex sight according to claim 10 , wherein said projector comprises a light emitting diode.

14. A firearm having a firing axis, said firearm comprising:
a reflex sight, said reflex sight comprising:
a housing mounted on said firearm, said housing defining a line of sight parallel to said firing axis;
a receptacle positioned within said housing underlying said line of sight, said receptacle having an opening facing said firearm;
an optical element comprising a reflector attached to a base, said base being received within said receptacle such that said reflector intersects said line of sight; wherein
said housing comprises a first shoulder projecting transversely to a plane of said reflector within said receptacle; and
said base comprises a second shoulder projecting transversely to said plane of said reflector, said first and second shoulders engaging one another when said optical element is positioned within said receptacle.

15. The firearm according to claim 14 , wherein said optical element is removable from said receptacle.

16. The firearm according to claim 14 , wherein said optical element is adjustably positionable relatively to said line of sight.

17. The firearm according to claim 14 , wherein said reflex sight further comprises a hood mounted on said housing, said hood surrounding at least a portion of said reflector.

18. The firearm according to claim 14 , wherein said housing further comprises a bottom plate covering at least a portion of an opening providing access to said receptacle.

19. The firearm according to claim 14 , wherein said reflector has indicia on a surface thereof.

20. The firearm according to claim 19 , wherein said indicia comprise a sight reticle.

21. The firearm according to claim 20 , wherein said sight reticle simulates a notch sight.

22. The firearm according to claim 14 , wherein said reflector comprises a collimating mirror.

23. The firearm according to claim 14 , further comprising a projector located within said housing, said projector projecting an image onto said reflector.

24. The firearm according to claim 23 , wherein said image comprises a virtual reticle.

25. The firearm according to claim 24 , wherein said virtual reticle comprises a dot.

26. The firearm according to claim 23 , wherein said projector comprises a light emitting diode.

27. A reflex sight for a firearm having a firing axis, said reflex sight comprising:
a housing mountable on said firearm, said housing defining a line of sight parallel to said firing axis;
a receptacle positioned within said housing underlying said line of sight;
a bottom plate covering at least a portion of an opening providing access to said receptacle;
an optical element comprising a reflector attached to a base, said base being received within said receptacle such that said reflector intersects said line of sight.

28. A firearm having a firing axis, said firearm comprising:
a reflex sight, said reflex sight comprising:
a housing mounted on said firearm, said housing defining a line of sight parallel to said firing axis;
a receptacle positioned within said housing underlying said line of sight, said receptacle having an opening facing said firearm;
a bottom plate covering at least a portion of said opening;
an optical element comprising a reflector attached to a base, said base being received within said receptacle such that said reflector intersects said line of sight.
