Description

I

HANDGUN IDENTIFICATION LIGHT TECHNICAL FIELD

The present invention relates to accessories for handguns, and particularly to a handgun identification light that is attachable to a handgun.

BACKGROUND ART

An old police tradition of requiring off-duty-p.laincloth.es officers to carry their weapons "always armed, always on duty" is being scaled back in police departments nationwide following the shootings of off-duty officers by colleagues who thought they were criminals. The policies require officers to respond to crimes even when they are not on duty. Supporters say the tradition also protects officers from criminals bent on revenge.

Nevertheless, critics point to shootings of officers in a variety of jurisdictions as reasons for change. Many jurisdictions have found themselves the target of civil rights, wrongful death, and the like, lawsuits over friendly fire officer shootings. In today's technological society, the incidence of any friendly fire activity should not be tolerated and begs for a technological solution. Moreover, often times a suspect would comment that an undercover police officer never identified himself, the situation leading to the suspect being seriously injured or killed by officer's weapons fire. Officers would claim that their shields were properly displayed.

However, during pursuit of a suspect, the shield would be lost or dislodged under the officers' clothing, the officer not having noticed that he/she is not properly identified. When the officer catches up with the suspect there's no shield. Several officers are now yell ing verbal commands to drop the weapon at different times. Their commands sound like chaotic noise from unidentified gun wielding persons, wherein the suspect may defensively assault officers, whereupon officers return fire with deadly consequences. The civilian community subsequently becomes upset with the officer(s), who now may have to stand trial for wrongful death or improper use of deadly force. The lawsuits may result in the jurisdiction having to pay out millions of dollars. A device is needed that would avoid the

aforementioned situation.

Additionally, a device that allows a suspect to see the amount of law enforcement manpower surrounding him will act as a deterrent and possibly cause the suspect to more easily surrender to the LEOs.

Thus, a handgun identi fication light solving the aforementioned problems is desired. DISCLOSURE OF INVENTION

The handgun identification light is a device attachable to a handgun, the device i lluminating the handgun with flashing blue and red l ights (having a color and flash pattern similar to the fami liar police vehicle identifying lights) to provide advanced, real time early warning to police officers who encounter a fel low off-duty-plainclothes or undercover officer during their response to the commission of a crime. The device has an on-off switch connected to a battery and (lashing LED's disposed along opposing sides of the device to provide high visibi l ity from both left and right sides of the device.

The device includes a tilt switch, grip switch, or gun motion sensor that detects when a user draws the weapon. By activation of the flashing red and blue light device on his weapon, an off-duty plainclothes or undercover police officer who draws the weapon becomes readily identifiable by other officers in proximity as a fellow law officer, thus avoiding misidentification and tragically resultant friendly fire incidents.

These and other features of the present invention will become readily apparent upon further review of the following specification and drawings,

BEST MODE FOR CARRYING OUT THE INVENTION

Figs 1 -3 show a first embodiment of a handgun identification light 5a that is intended to help keep law enforcement officers (LEOs) from shooting each other, and to give notice to suspects during an incident where it may not be clear who is who based on appearance and mode of dress. Figs. 1 -2 show the handgun identification light 5a attached to an automatic or semi-automatic pistol.

The handgun identification light 5a has a resilient, semi-rigid flexible grip sheath 1 l a made from rubber that extends from a rear portion of a slotted, elongate, high impact- resistant, plastic member 1 l b, which is custom-fitted to the contour of the gun G's frame 50. When attaching the device 5a, the trigger guard TG of gun G can fit through the slot L of the co-joined plastic member 1 l b and grip sheath 1 l a. The elastic, flexible, open-ended grip sheath 1 ! a snugly fits over the grip portion GR of handgun G, while still allowing access to load and remove a magazine from the bottom of the grip. The plastic member 1 l b forms a channel having sides that extend to just below the slide of the automatic, and extends from the rear of the grip to just beyond the trigger guard beneath the barrel B of the gun G. The channel of the plastic member 1 l b may form a snap fit or friction fit to the frame of the handgun G.

Red flashing LED lights 12a and a blue flashing LED light 1 2b are disposed along opposing sides of the plastic member I l b and are plainly visible from both sides of a gun equipped with the device 5a. The grip sheath I l a is open from its top portion to its bottom portion and snugly fits over the grip portion GR of the handgun G, while the slotted elongate member 1 l b snugly snaps into place around the frame 50 of gun body, extending under a portion of the barrel B of handgun G. The grip sheath 1 l a may be open at the bottom to permit removal of the magazine to reload the pistol without having to remove the handgun identi fication light 5a.

A battery power source BAT can be disposed inside of the grip sheath 1 l and supply power to an electronic circuit 990 (shown in Fig. 10) having a cutoff switch 14, which is disposed on the upper rear portion of the grip sheath 1 l a. Circuit 990 including its microprocessor-memory combi nation 940, programming input P, actuation input S, LED dri ver 960, battery BAT, cutoff switch 14, actuator 921 and LED array 9 1 8 is exemplary. Such LED driver circuits are well known to those of ordinary skill in the art. The LED actuator 921 may comprise a light activation switch 16, which may be disposed on a medial rear portion of the grip sheath 1 1 a. When the grip of the gun G is grabbed, pressure is applied to the light activation switch 16, which turns on LED light array 9 1 8 which may be comprised of LED lights ! 2a and 12b. The LED lights 12a and 12b preferably light up in a blinking or flashing pattern when activated.

As shown in Figs 4-6, an alternative embodiment of the handgun identi fication light 5b, again for use with an automatic or semi-automatic pistol G, has two longitudinally extending side members 40b, which are joined by laterally extending top crossmembers 40a to form a U-shaped, partially open-topped barrel clamp that mounts to the slide of the gun G from the top. The gap between the crossmembers 40a permits ejection of spent cartridges from the chamber when firing the gun G. Setscrews 13 along the lower portion of the side members 40b are adjustable to secure the side members 40b to the slide of the handgun G. The rear portion of the longitudinally extending side members 40b includes a vertical arrangement of finger grips FG to facilitate the user pulling the slide of the gun G for adjustment, fire preparation, and the like.

Disposed on both side members 40b are the LED lights 12a and 12b. A cutoff switch 14 and activation sensor 160 are disposed on one of the side members 40b. The battery power source BAT may be disposed inside the barrel cover portion of device 5b. The circuitry 990 interconnecting the cutoff circuit, battery and LED lights may also be connected to the activation sensor 1 0, which activates the LED lights 12a and 12b when the gun is either tilted into a fire-ready position, or, alternatively, when the gun is in motion outside of its holster.

Yet another exemplary embodiment of a handgun identification light, designated generally as 100 in the drawings, is shown in Figs 7-9. As shown in Fig. 7, the handgun identi fication light 100 has a switch or grip-sensitive actuator 103 attached to the grip of the handgun by a flexible, resilient band 102. The switch or actuator 103 has a cable 104 extending therefrom to a hollow slide body 106 and may connect to the S input of

microprocessor-memory combination 940 in programmable control electronics 990 shown in Fig. 10. When the grip sensitive actuator 103 detects a grip, or alternatively, a momentary finger press, the flashing USD' s on the handgun identification light 1 0 arc energized to thereby alert any observer that a Law Enforcement Officer's weapon has been drawn. The hollow slide body 106 includes a rear end plate 108a. A plurality of light emitting diodes (LBDs) 1 10 are disposed along sides of the hollow slide body 106. The entire unit removably attaches to the firearm G. Additionally, Fig. 8 shows a front end plate 108b attached to the front portion of the hollow slide body 106. Additional LEDs 1 12 are mounted on the front end plate 108b, or are visible through openings in the front end plate 108b.

The exploded, perspective view of Fig. 9 most clearly shows the USB recess 901 disposed in the hollow slide body 106. A USB receptacle or port is capable of being mounted in or accessible through the USB recess 901 and is connectable to programming port input P of microprocessor 940, shown in Fig. 10. A USB cover 900 is designed to cover and protect the receptacle when the handgun identification light 100 is not being programmed via a USB cable attached to the receptacle.

An upper portion of hollow slide body 106 has a pair of chamfered edges 902 designed for a tight slide fit over a slide rail portion of the handgun G. A slide lock recess 904 in the slide body 106 accepts a slide lock 906 between a break in the chamfered edges 902. The slide lock 906 has a chamfered edge that also engages the slide rai l of handgun G, and can be tightened onto the slide body 106 using a threaded stud 912 and its associated tightening knob 9 14 to securely thread the stud 9 12 into a threaded bore defined in the slide lock 906.

Fig. 10 shows an exemplary electronic circuit 990 for the handgun identification tight. The circuit 990 includes an LED driver circuit 960, and a power source BAT that can be housed inside the hollow slide body 106. It is contemplated that the circuit 990 may control the color, the intensity, and the flashing pattern of the side LEDs 1 10 and the front LEDs 1 12, which are disposed in side LED holes 908 and front LED holes 909, respectively. Threaded fasteners F secure the rear plate 108a and the front plate 108b to rear and front ends of the slide body 106, respectively.

It is to be understood that the present invention is not limited to the embodiments described above, but encompasses any and all embodiments within the scope of the following claims.
