Benefits of technology

[0010]The firearm laser sighting device of an embodiment of the present invention is mounted in the recoil spring guide chamber of a semi-automatic handgun. The laser emits a constant light that allows the shooter to aim at a specific target. The laser light is then modulated to emit a pulsed light at or about the time of firing the weapon. The emission of the modulated laser light can be adjusted to pulse the laser light for any duration of time, from a few microseconds to a couple of seconds. The activation of the modulated laser light can be triggere

Problems solved by technology

However, they are most often associated with awkward devices mounted externally on the firearm to emit a laser pulse upon “firing”.
This higher amplitude sound wave stimulates the laser light emitting device, such as a laser diode, to emit a laser pulse, the duration of which may be adjusted to determine if the trainee is “pulling” the weapon upon firing, which can result in missing the target or at least not hitting the “center mass” of the targeted object.

Embodiment Construction

[0016]FIG. 1 shows a semi-automatic handgun 10 having an external slide ejection element 11. Non-limiting examples of such semi-automatic handguns include those manufactured by Colt (the most common of which is the Model 1911 and its progeny), Browning, Sig Sauer, Beretta, Glock, Heckler & Koch, and Smith & Wesson.

[0017]Such automatic and semi-automatic handguns use a recoil compression spring to absorb the energy from the rearward motion of an external slide ejection element. The stored energy is available to eject a spent cartridge from the handgun after the bullet has been fired and to enable another live round to be chambered from the magazine into the receiver of the barrel. The spring 12 and spring guide 14 are located in a recoil spring guide chamber 13 which is positioned under and parallel with the barrel 16. The recoil spring guide chamber 13 is a cavity which is closed at a first end 15 and open at the opposing or second end 17. The spring guide 14 is hollow and accommoda...

Abstract

A laser sighting device for a semi-automatic handgun having a recoil spring guide chamber housing a recoil spring surrounding a spring guide. The laser sighting device includes a pulse modulated laser received within the spring guide, having an input and a light output for emitting a pulse modulated laser light aligned with a path of a bullet fired by the handgun; and a sensor for detecting firing of the handgun, having an output coupled to the input of the pulse modulated laser. When the sensor detects the handgun has been fired, the output of the sensor triggers the pulse modulated laser to emit a train of pulses of laser light.

Description

REFERENCE TO RELATED APPLICATIONS[0001]This application claims one or more inventions which were disclosed in Provisional Application No. 61 / 322,407, filed Apr. 9, 2010, entitled “PULSE MODULATED LASER SIGHT FOR FIREARMS”. The benefit under 35 USC §119(e) of the United States provisional application is hereby claimed, and the aforementioned application is hereby incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention pertains to the field of laser sights for firearms. More particularly, the invention pertains to a modulated laser pulse to indicate the trajectory of a real or simulated firearm projectile.BACKGROUND OF THE INVENTION[0003]Various devices have been developed to aid in the field of firearm training, such as those for use by law enforcement and military personnel. Lasers mounted to the training firearm have become popular devices. However, they are most often associated with awkward devices mounted externally on the firearm to emit a laser pulse upon “f...
