Abstract

This invention comprises an illuminated gunsight attachment for mounting on a weapon to permit the user to aim and shoot in low-light conditions. The illuminated gunsight includes a light-emitting diode for a front sight and an illuminated rod for a rear sight. The invention also includes a magnetic switch which automatically activates the power circuit to illuminate the sights as the revolver is withdrawn from its holster. The illuminated gunsight attachment is mounted unobtrusively on the barrel of a weapon to permit use of either conventional sight posts of the weapon or the illuminated sights of the invention. In one embodiment the rear sight is formed by a set of parallel lines comprised of flourescent markings located on opposite sides of an illuminated line. The invention also includes a firearm holster with a magnet thereon for activating the illuminated gunsight as it is withdrawn from the holster.

Claims

1. An illuminated sighting device for external attachment to a weapon to enable a user to aim and shoot a weapon in daytime or low-light conditions comprising:

a housing for external attachment to a weapon, said housing having a front end and a rear end, said housing including a sighting channel extending along said housing, said sighting channel having a bottom section;

a light-emitting diode located in the bottom of said sighting channel to form a first illuminated sight of a first intensity, said light-emitting source attached to one end of said housing;

a light-conducting rod having a first end and a second end, said first end of said light-conducting rod located adjacent said light-emitting diode to transmit illumination from said light emitting diode to said second end of said light-conducting rod to form a second illuminated sight, said second illuminated sight located in the bottom of said sighting channel and attached to said housing, said second illuminated sight of a second intensity, said second intensity different from said first intensity, said second illuminated sight and said first illuminated sight spaced from each other to enable a user to aim a weapon attached to said housing during low-light conditions; and

means in said housing to permit alignment of said sighting device with respect to a weapon attached thereto.

2. The invention of claim 1 further comprising:

means for powering said light-emitting source; and

switching means connected to said means for powering said light emanating source to switch on and off said light-emitting source.

3. The invention of claim 2 wherein said switching means includes:

a magnetic switch connected to said power means, said magnetic switch having a normally closed position to thereby supply power to said light-emitting source.

4. The invention of claim 3 further comprising a holster having a magnet attached thereto, said magnet oriented to activate said switching means to open said magnetic switch to turn off the power to said light-emitting source when a weapon with said illuminated sighting device is located in said holster.

5. The invention of claim 1 wherein said second illuminated sight comprises an illuminated region extending along said housing.

6. The invention of claim 1 wherein said second sight comprises a light-conducting member having a first end and a second end forming a second illuminated sight for directing light toward the user, with said second illuminated sight projecting upward from said first sight.

7. The invention of claim 1 wherein said light-conducting member comprises an acrylic rod having an illuminated end, said illuminated end forming a second sight.

8. The invention of claim 5 wherein said illuminated region comprises a light-conducting rod having an elongated planar face, said planar face being illuminable by said light-emitting source to provide an illuminated region around said light-conducting rod.

9. The invention of claim 8 wherein said illuminated region has a width of less than 0.040 inches.

10. The invention of claim 2 wherein said switching means includes a second override switch for shutting off the power to the light-emitting source.

11. The invention of claim 2 further comprising a means for adjustably mounting said illuminated gunsight on a barrel of a firearm.

12. The invention of claim 11 wherein said mounting means further comprises removable brackets to grippingly engage the barrel of a firearm.

13. The invention of claim 2 wherein said sighting device includes means to vary the intensity of the light emanating from said light-emitting source.

14. The invention of claim 1 wherein said sighting device further comprises elongated fluorescent regions located on said housing to provide sight lines for aiming a weapon in natural or artificial light.

15. An illuminated sighting device for attachment to a firearm to enable a user to aim and shoot a firearm with either conventional sights or the illuminated sighting device comprising:

a housing for attachment to a firearm;

an elongated U-shaped sighting channel located in said housing, said channel having a first end and a second end;

a light-emitting source for supplying light to produce a first illuminated sight, said light-emitting source located in one end of said sighting channel; and

a second illuminated sight, said second illuminated sight located in said second end of said sighting channel, said second illuminated sight and said first illuminated sight operable to enable a user to aim a weapon attached to said housing.

16. The invention of claim 15 wherein said elongated U-shaped channel includes a strip of fluorescent material to provide a rear sight.

17. The invention of claim 15 wherein said elongated U-shaped channel includes a light-transmitting member having a region for emanating light through said elongated region.

18. The invention of claim 17 wherein said elongated U-shaped channel includes an elongated strip of fluorescent material located parallel the light emanating from said elongated region.
