Abstract

A sighting device is mountable to a gun. The device includes a light source (preferably a laser), a power source connectable to the light source and a mount attachable to the gun so that the laser is juxtaposed either the top surface of the gun or a side surface of the gun. In one embodiment, the sighting device includes a bottom rail mountable in a slot on the gun, wherein the slot is preferably positioned on the top surface of the gun. The sighting device may also include a mechanical sight that functions as the rear mechanical sight on the gun and/or a secondary light source.

Claims

1. A sighting device for use with a gun, the sighting device having a laser, a power source connectable to the laser, a mechanical sight which is a frame component between two spaced-apart members that extend upward from the top surface of the gun, and that is visible to a user and through which the user can view a target when aiming the gun, and a mount, wherein the power source for the laser is spaced apart from the laser and the mount is positioned beneath the laser, wherein the mount is mechanically attachable to a slot on a surface of the gun, and wherein a user can simultaneously sight a target with the mechanical sight and laser.

2. The sighting device of claim 1 that has a height of no more than ¾

″

from the surface.

3. The sighting device of claim 1 that has a height of no more than ½

″

from the surface.

4. The sighting device of claim 1 that has a height of no more than ⅜

″

from the surface.

5. The sighting device of claim 1 that is no greater than 3″

in length.

6. The sighting device of claim 1 that is no greater than 2″

in length.

7. The sighting device of claim 1 that is no greater than 1½

″

in length.

8. The sighting device of claim 1 that is no greater than 0.9″

in length.

9. The sighting device of claim 1 wherein the power source is one or more batteries.

10. The sighting device of claim 9 wherein the power source is a plurality of 1-3V silver oxide batteries.

11. The sighting device of claim 10 wherein the power source is four silver oxide batteries between 1-3V.

12. The sighting device of claim 1 that further includes a light source adjustment apparatus for adjusting the position of the laser, wherein the light source adjustment apparatus is a flexible material that surrounds at least part of the laser and fits within a housing that retains the light source adjustment apparatus and the laser.

13. The sighting device of claim 12 wherein the light source adjustment apparatus includes an inner cavity that retains at least part of the laser.

14. The sighting device of claim 13 wherein the light source adjustment apparatus has a conical shape.

15. The sighting device of claim 12 wherein the light source adjustment apparatus is moved by adjusting one or more screws that pass through the housing that retains the light source adjustment apparatus and the laser, thereby adjusting the position of the laser.

16. The sighting device of claim 1 that includes a housing, the housing including the two spaced-apart members, which comprise a first canister for retaining the laser and a second canister for retaining the power source for the laser.

17. The sighting device of claim 16 wherein at least part of the housing is comprised of metal.

18. The sighting device of claim 17 wherein at least part of the housing is comprised of aluminum.

19. The sighting device of claim 17 wherein at least part of the housing is comprised of steel.

20. The sighting device of claim 19 wherein at least part of the housing is comprised of stainless steel.

21. The sighting device of claim 19 wherein at least part of the housing is comprised of machine injection molded steel.

22. The sighting device of claim 16 wherein the housing includes a connective portion between the first canister and the second canister.

23. The sighting device of claim 22 wherein the connective portion includes the mechanical sight.

24. The sighting device of claim 16 wherein the mechanical sight is positioned between the first canister and the second canister.

25. The sighting device of claim 1 that further includes an aperture for accepting a set screw, the aperture formed through the mount and configured so that the set screw can pass through the mount and apply pressure to the slot to assist in retaining the sighting device to the gun.

26. The sighting device of claim 1 that further includes an integrated circuit board is configured to cause the laser to pulse when it emits light.

27. The sighting device of claim 26 wherein the integrated circuit board is configured to cause the laser to pulse at 1000 times per second when it emits lights.

28. The sighting device of claim 1 wherein the integrated circuit board is configured to cause the laser to draw less than 10 milliamps of power when it emits light.

29. The sighting device of claim 1 wherein the integrated circuit board is configured to cause the laser to draw 6-8 milliamps of power when it emits light.

30. The sighting device of claim 27 wherein the integrated circuit board is configured to cause the laser to have a 50% duty cycle as it pulses.

31. The sighting device of claim 1 wherein the mount is configured to be pressure fit into the slot.

32. The sighting device of claim 1 wherein the gun has a top surface and a back surface, and the sighting device is mountable to a slot on the top surface of the gun, the slot being within 2″

of the back surface.

33. The sighting device of claim 32 wherein the slot has a dovetail shape.

34. The apparatus of claim 32 wherein the laser is mounted on a surface of the gun and extends no farther than ¾

″

outward from the surface on which it is mounted.

35. The apparatus of claim 32 wherein the laser is mounted on a surface of the gun and extends no farther than ⅜

″

outward from the surface on which it is mounted.

36. The sighting device of claim 1 wherein the mechanical sight includes a sighting insert positioned on a surface of the mechanical sight.

37. The sighting device of claim 36 wherein the sighting insert is luminescent.
