ABSTRACT:
FIELD OF INVENTION
The present invention relates to firearm mounted illumination devices and particularly related to an illumination device mounted on the trigger guard of a firearm while providing a convenient touch switch for instant activation
BACKGROUND OF THE INVENTION
The use of illumination devices to aid in marksmanship and personal defense is known in the prior art. Lights have been mounted, generally, in three locations on a weapon: on the barrel, underneath the barrel, and on the magazine. These illumination devices, while suitable for their individual purposes are not suitable for the purpose of the present invention, namely providing an illumination device that is mountable on any handgun and allows for holstering the weapon without removal of the device and activation of the device without altering the user's grip on the weapon. For example: U.S. Pat. No. 5,685,105 to Teetzel (1997); U.S. Pat. No. 5,654,594 to Bjornsen, III, et al. (1997); U.S. Pat. No. 5,560,703 to Capps, III (1996), U.S. Pat. No. 5,522,167 to Teetzel (1996); U.S. Pat. No. 5,430,967 to Woodman, III, et al. (1995); U.S. Pat. No. 5,400,540 to Solinsky, et al. (1995); and U.S. Pat. No. 4,856,218 to Reynolds, Jr. are all illustrative of the prior art.
JAMES W. TEETZEL
APPARATUS FOR ATTACHING A FLASHLIGHT TO A FIREARM
U.S. Pat. No. 5,685,105
Teetzel teaches a flashlight mounting module that may be mounted on the underside of a handheld firearm. Switches and the power source are contained in specially modified handgrips. The module is attached by using an attached railing system to connect a mount adapter and a dovetail interface to attach the flashlight module to the mount adapter.

ERGONOMIC ELECTRICAL CURRENT SWITCHING SYSTEMS
U.S. Pat. No. 5,654,594
The Bjornsen patent teaches the use of a “touch switch” whereby current is carried by two conductive strips. The strips are normally separated, however, when squeezed together they complete a circuit. The '594 patent claims the use of such a switch on the handle of a weapon.
LEWIS W. CAPPS, III
HANDGUN LIGHT MOUNT
U.S. Pat. No. 5,560,703
This invention discloses a mount for a flashlight positioned on the bottom of a weapon's magazine.
JAMES W. TEETZEL
SWITCH APPARATUS
U.S. Pat No. 5,522,167
The switching appetites disclosed in this invention uses a tritium vial, embedded on the posterior side of the trigger guard/grip, a hole bored through the trigger, and a sensor on the anterior side of the trigger guard area. The sensor reads the emissions from the vial, through the hole. When the user places his finger on the trigger, and correspondingly over the hole, the sensor reads a drop in the emissions and activates the flashlight.
WALLACE E. WOODMAN, III, ET AL.
AIMING ASSISTANCE DEVICE FOR A WEAPON
U.S. Pat. No. 5,430,967
The mounting structure for this invention utilizes mounting rails on the underside of the weapon's barrel. It teaches a side opening structure to allow the user to mount the structure on the rails
KENNETH S. SOLINSKY, ET AL.
AIMING LIGHT AND MOUNTING ASSEMBLY THEREFORE.
U.S. Pat. No. 5,400,540
The invention teaches a multi-positioning switch for a light mounted on the side of a rifle barrel. The switch is positioned for maximum convenience of the rifle user at approximately where a user's forward arm would hold the rifle.
EDWARD C. REYNOLDS, JR.
LIGHT BEAM ASSISTED AIMING OF FIREARMS
U.S. Pat. No. 4,856,218
The invention discloses a light beam emitting assembly mounted underneath the barrel of a rifle or pistol. The assembly of the mount to the weapon requires the replacement of certain parts of the weapon with others that will similarly function and simultaneously hold the light housing.
EDWARD C. REYNOLDS, JR.
LIGHT BEAM ASSISTED AIMING OF FIREARMS
U.S. Pat. No. 4,777,754
This invention, also by Reynolds, Jr., also replaces parts of the weapon for others that will perform similarly while holding the light housing.
While the aforementioned inventions accomplish their individual objectives, they are not suitable for the purpose of this invention, namely to provide a universally adaptable, slim line, firearm mounted illumination device with a dual switch mechanism that is activated by a switch positioned directly underneath the trigger guard
The '594 patent discloses a similar switching mechanism; however, the activation mechanism is located on the grip of the weapon, not underneath the trigger guard. As such, it would be more prone to accidental activation and would require adaptation to match different lengths with different pistols and illumination devices. The '105, and '967 patents disclose under barrel mounted illumination devices and targeting aids; but, all of the devices require mounting on an existing or added rail system. The '218 and '754 patents disclose replacing parts of the weapon in order to mount the claimed aiming devices. Many devices, including the '703 patent, are simple mounts that require a generic or specialized flashlight and do not provide a switching mechanism. Other devices, such as the '167 and '105 patents mount switches on the weapon. These devices, however, require relatively extensive modification of the weapon. None of the inventions disclosed also provides a dual switching system including a compression or “touch” switch located directly underneath the trigger guard of a pistol. None of the disclosed inventions disclose a mounting means focused on the trigger guard of the weapon, a universal component. In this respect, the illumination device according to the present invention departs substantially from the usual designs in the prior art. The device mounts directly onto the trigger guard of any firearm. The dual switch features a compression switch and a master switch. In doing so, this invention provides a new and useful light that not only is usable on any handheld firearm, but also provides a conveniently located compression switch, allowing for activation without altering a user's grip, and therefore allowing greater concentration on the user's target, and a master power switch for continuous activation if the user so desires.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of illumination devices, this invention provides an improved illumination device for hand held firearms. As such, the present invention's general purpose is to provide a new and improved defense light that will be useful on any handheld firearm without modification of said firearm while presenting a new and useful switching mechanism that allows for instant illumination when desired by the user.
The defense light comprises a battery and light housing that is ideally aligned along the barrel of a pistol. Towards the rear portion of the housing, away from the light is a mounting means. The mounting means attaches the housing to the front portion of the pistol's trigger guard and holds the housing securely against the trigger guard and barrel of the pistol. The housing also features an appendage extending rearward, from beneath the mounting means. The appendage contains the touch switch device and is shaped and sized to correspond to the trigger guard of the pistol. The housing also features a master switch for continuous activation of the light. Due to the location of the light and switch relative to the weapon, many advantages are provided by this invention over the prior art. The foremost of which is that a user need not relearn firing techniques. In order to activate the light, the user need only press the touch switch with the fingers already located against the trigger guard, and also, therefore, already against the touch switch. As such, there is no need to deviate from the recommended two-handed firing position. The central location, under the barrel, is also convenient for both left and right handed users. No modification to the weapon is required as with some illumination devices and the defense light according to the present invention also does not interfere with m
