Description

FIELD OF THE INVENTION

The present invention is directed to a weapon mountable illumination device which is intended to provide a modular and mobile lighting solution which mitigates problems associated with snagging, shadow casting, imbalance associated with the mounting to a weapon, and overheating of elements.

BACKGROUND OF THE INVENTION

In the conduct of law enforcement and military operations, weapon-mounted tactical lighting has become mission critical equipment in most operations wherein such equipment provides a high level of value in achieving success in a given operation.

Handheld tactical lighting, generally used with pistols, requires the use of one hand to operate the weapon while the other hand of the operator is used to illuminate targets or areas of interest beyond the muzzle-end of the weapon.

Weapon-mounted lighting, commonly used with long guns (shotguns, rifles, carbines, and other longer barreled firearms) allows the use of both hands in operating the weapon while providing illumination to targets or areas of interest beyond the muzzle-end of the weapon. Although weapon-mounted lighting is typically used with long guns which require two-handed operation, weapon-mounted lighting has also been adapted for use on pistols.

Weapon-mounted lighting in weapon centric operations allows an operator a commonly used term for personnel involved in military operations to provide illumination generally in the direction of the muzzle of the weapon while maintaining use of both hands for weapon handling and other operation related tasks.

Benefits of weapon-mounted lighting typically include: positive target identification in low-light situations, disorientation and/or temporary blinding of targets, or emitting infrared light for the purposes of illumination of areas in the event the operator is using night-vision enabling equipment.

SUMMARY OF THE INVENTION

An existing solution surrounding weapon-mounted lighting involves the mounting of a traditionally-shaped, cylindrical flashlight to the side of the weapon. Due to the placement of the flashlight on the side of the weapon, this can result in the casting of a shadow on the opposite side of the barrel from where the flashlight is mounted. A shadow in low-light operations can result in a potential target or threat being obscured from illumination, thus creating a potentially life-threatening situation for the operator.

A common tactic in efforts to mitigate the casting of a shadow involves the mounting of the flashlight as far forward and closer to the muzzle-end of the weapon, such as seen in U.S. Pat. No. 7,941,960 to Matthews, et al. (“Matthews”) incorporated in its entirety herein for all purposes. Although this decreases the casting of shadows, this results in negatively affecting the weapon's weight and balance. Resultantly, the operator's ability to accurately engage targets is also negatively affected. Furthermore, the mounting of a flashlight toward the muzzle-end of a weapon creates a protuberance which can result in the snagging or catching of the weapon on obstacles including, but not limited to, communication cords, pistol lanyards, seatbelts, wires, or other cable-like lines present in military and/or law enforcement vehicles, boats, and aircraft. While conducting vehicle-mounted operations, it is optimal for an operator to be able to exit the vehicle quickly and bring the weapon to bear with zero interference. Prior art illumination devices (i.e. externally attached cylindrical flashlight-shaped devices) serve as a prominent encumbrance to speed and accuracy. The positioning of a standard external flashlight is such that the vehicle seatbelt or harness will likely clear the barrel of the gun, but grab the light fixture, causing not only a delayed exit, but more importantly a negative impact to the operator's ability to accurately engage threats. Operators have reported incidents of weapon-mounted flashlights catching on obstacles during ship-boarding operations, close-quarters combat operations, room-clearing operations, and during rappelling operations from buildings or fast-rope operations from helicopters. An operator catching their weapon in any operation can pose a life-threatening risk. For instance, during a rappelling or fast-rope operation, the catching of one's weapon can result in an uncontrolled fall from heights in excess of 40 feet.

Embodiments of the present invention surround a weapon-mounted illumination device providing lighting for an operator in a manner which does not cast shadows and provides streamlined form factor which provides snag-free operation due to the form factor in close proximity with existing aspects of the weapon.

Solutions to the above discussed problems have been proposed involving the mounting of a lighting device, such as a flashlight, to a weapon aligned with the muzzle-end of the firearm. The problem with such solutions surrounds the percussion and heat associated with the repeated firing of the firearm. The percussion and heat adversely affect the performance of the lighting device, as well as the operation of the weapon. The side-mounting of a flashlight to the forward aspect of a weapon may negatively affect the intended operation of the weapon due to imbalance and result in weapon malfunction.

A rail interface system commonly referred to as a “rail”, “rail integration system”, “rail accessory system” is a standardized apparatus of the attachment of accessories to firearms. Rail interface systems commonly provide a handguard offset surface of a barrel, wherein the handguard has one or more rails in accordance with MIL-STD-1913, STANAG 4694 specifications, or other rail interface systems known to those skilled in the art. The rail interface system allows the rapid attachment of accessories to a firearm by sliding the accessory onto a rail having undercuts, resulting in a T-shaped rail, and locked into place. A commonly used rail interface system for carbine weapons, such as the M-4, M-16, and AR-15, is commonly referred to as a “Picatinny Rail” although embodiments of the present invention are configured to interconnect with all rail accessory systems known to those skilled in the art. Certain rail interface systems provide handguard, configured to mount axially around a barrel of a firearm, having a total of four rails angularly offset at 90-degree increments, resulting in an octagonal profile wherein alternating surfaces have an accessory rail such that a top surface, bottom surface, left surface, and right surface of the handguard have accessory rails. It is an aspect of certain embodiments to provide an illumination device configured to slidably mount to a rail interface system having an octagonal profile. It is an aspect of certain embodiments of the present invention to be slidably mountable to a rail integration system having at least one rail integration system.

It is an aspect of certain embodiments to interconnect with firearm accessory mounting systems such as those disclosed by U.S. Pat. No. 8,925,236 to Mayberry, at al. (“the '236 patent”), U.S. Pat. No. 9,239,209 to Mayberry, at al. (“the '209 patent”), and U.S. Pat. No. 9,239,210 to Mayberry, at al. (“the '210 patent”), each of which are incorporated by reference in their entirety for all purposes. It will be appreciated that the mounting of the present invention disclosed herein to weapon accessory mounting systems known to those skilled in the art, such as those commonly known as KeyMod® and M-LOK®, are within the spirit and scope of the present invention.

Certain existing technologies, such as U.S. Patent Publication No. 2017/0038178 to Pinilla (“Pinilla”), herein incorporated by reference in its entirety for all purposes, propose a solution wherein a lighting device is integrated into a rail interface system. Pinilla teaches the incorporation of an illumination device within an internal aspect of a rail interface system wherein lighting elements are disposed between the rail interface system and the placement of the batteries creating a protuberance above where a top rail of the rail interface system would otherwise be. Furthermore, the removal of the illumination device of Pinilla requires the removal of the rail interface system as opposed to the removal of the illumination device alone. The close proximity of electrical and battery elements to the barrel would result in the exposure of electrical elements and batteries to high heat and percussion. Furthermore, the protuberance of the battery compartment negates the use of the top rail of the rail interface system and precludes the mounting of certain accessories to the weapon.

It is an aspect of the present invention to provide a weapon-mounted illumination device which is modular and does not limit the mounting of accessories to a rail interface system when the illumination device is not necessary. It is a further aspect of the present invention to allow the mounting of an illumination device as desired—toward the forward end (muzzle end) of the weapon, or further aft, dependent on the operator's preference or arm length and other physical body characteristics without impediment to or front existing elements such as back-up iron sights. It is a further aspect of the present invention to allow the attachment and removal of an illumination device without requiring the removal of the front-sight post.

It is an aspect of the present invention that the mounting of an illumination device mounted to a weapon's rail interface system does not inhibit or interfere with the mounting or operational use of traditional sights such as Backup Iron Sights (BUIS) or other commonly used sighting systems including, but not limited to products manufactured by: Aimpoint®, ACOG®, EOTECH® or AR-Scopes®.

It is a further aspect of the present invention to maintain the functionality of the top rail of a rail interface system when an illumination device is mounted to the weapon's rail interface system. Certain embodiments of the present invention surround the use of a cuff form having an open top aspect wherethrough the top aspect of a firearm is received. This allows an operator to rapidly affix or remove the present invention from the firearm without impediment to or from aspects of the weapon such as backup iron sights, the slide of a semi-automatic pistol, or accessories mounted to the top aspect of the weapon using a rail interface system.

Existing solutions, such as Pinilla, teach the use of a wired remote illumination activation switch which is placed remotely from the illumination device in close proximity to the operator's hands, such as near the trigger-guard of the weapon. Such switches may result in unintentional activation of the illumination device which may inadvertently alert a target to the presence of an operator during covert operations, or reduce the visual acuity of a fellow operator resulting in potentially dangerous circumstances.

It is an aspect of the present invention to provide an illumination device wherein activation switches are configured in a manner which mitigates accidental actuation to prevent the inadvertent turning of the illumination device on or off. Switches of certain embodiments are integrated into the weapon mountable illumination device to provide tactile control of power and alternative functions of the weapon mountable illumination device. Certain embodiments include switches on both the left side and the right side of the weapon mountable illumination device thereby allowing the ambidextrous functionality during operations.

It is an aspect of the present invention to provide a power indicator to an operator in a manner which is seen only by the operator in a non-distracting manner. Certain embodiments comprise a pin-hole sized blue-light facing rearward such that the blue power indicator is viewable by an operator when the weapon is held in a firing position.

It is an aspect of certain embodiments to provide annular or semi-annular lighting as opposed to individual beam configurations as found with a flashlight mounted on the side of a weapon. Annular lighting provides lighting from 360-degrees around the barrel of the weapon and illuminates beyond the muzzle-end of the weapon. As such, an annular lighting solution negates the shadow casting effects of a beam lighting configuration. It will be appreciated that annular lighting, for the purposes of this instant application includes but is not limited to the use of a continuous annular lighting element, a plurality of lighting elements (such as LEDs) disposes at radial intervals surrounding the barrel of a weapon, or one or more lighting elements configured to distribute illumination around the barrel of the weapon.

Certain existing technologies, such as U.S. Pat. No. 7,954,273 to Richard Swan (“Swan), U.S. Patent Publication No. 2009/0122527 to Robert Galli (“Galli”), U.S. Patent Publication No. 2007/0039226 to John Stokes (“Stokes”); and U.S. Pat. No. 9,062,933 to John Allen, et al. (“Allen”)—each herein incorporated by reference in its entirety for all purposes—attempt to provide lighting forward of an operator's weapon. However, such technologies do not solve shadow-casting associated with the forward aspect of the weapon Some of such technologies, such as Swan, do not allow the adjustability of the device to permit an operator to place the lighting device at a desired distance to permit access to the device, or to allow as use as an ancillary grip, within reach for functions such as turning the illumination device on and off.

It is an aspect of the present invention to provide a weapon mountable illumination device which mitigates shadow casting though the use of a plurality of lighting elements configured to provide illumination forward of a firearm and operator. It will be appreciated that the term “forward” as used herein is not limited to a unidirectional aspect, but all aspects which are forward of the weapon and operator including a hemispherical field of view. It is an aspect of certain embodiments that a plurality of lighting elements work in concert to provide illumination forward of the firearm in a manner that the light cast provides a harmonized and/or uninterrupted lighting effect.

A further aspect of certain embodiments of the present invention include multiple functionalities such as, but not limited to: strobing, pattern flashing, white light, infrared illumination, colored LED light such as red or green light, and less-lethal functionality such as those taught by U.S. Pat. No. 6,190,022 to Tocci, et al. (“Tocci”) incorporated herein in its entirety for all purposes. It is a further aspect of certain embodiments to allow the selection of particular modes through the use of a selector switch.

It is an aspect of the present invention to allow the operation of a laser independently of a lighting element. It is a further aspect of the present invention to allow the selection of a first mode of the operation of the laser and lighting elements wherein contacting or depressing the respective switch toggles the laser or lighting element on until the switch is contacted again. Another aspect of the present invention allows the selection of a second mode of the operation of the laser and lighting elements wherein contacting or depressing the respective switch toggles the laser or lighting element on until the respective switch is released. Yet another aspect of the present invention allows the selection of a second mode of the operation of the laser and lighting elements wherein contacting or depressing the respective switch does not illuminate the laser or lighting element thereby preventing inadvertent illumination as may be desired in clandestine operations or simply to conserve battery power.

Certain embodiments of the present invention comprise an illumination device mountable to a rail interface system wherein the illumination device is independent of a weapon foregrip and mounted adjacent to the barrel, while embodiments comprising an integrated foregrip for a weapon are within the spirit and scope of the present invention.

Embodiments of the present invention comprise an illumination device manufactured from aluminum, durable polymers, composites and/or rubber. It will be appreciated however, that embodiments constructed with alternative materials known to those skilled in the art are within the scope and spirit of the present invention.

It is an aspect of certain embodiments to provide an illumination device which is neutrally buoyant such that when used in water-based operations, the illumination device does not affect the buoyancy of the weapon and system of accessories in a positive or negative manner.

Existing solutions such as those taught by Pinilla rely on the operator engaging the forward aspect of a firearm by the handguard or rail, such as a Picatinny rail. These handguards and shrouds rely on an operator to engage the forward aspect of the firearm with an upward-turned hand and gripping the handguard or rail. When gripping a handguard, an operator may find the need to continually readjust their grip of the firearm, wherein these moments in which an operator readjusts their grip may result in impaired ability to respond quickly to a threat.

It is an aspect of certain embodiments to provide a finger hold which extends downward from the forward aspect of the weapon wherein an operator is able to engage the firearm mounted illumination device with at least one finger to provide further support and stabilization to the forward aspect of the firearm. A finger hold as disclosed herein provides a specific location for an operator to engage the forward aspect of the firearm consistently and repeatedly. When engaged with a finger hold, an operator is able to support the firearm vertically while pulling the firearm toward themselves to increase support, maneuverability, and move the firearm more quickly. Furthermore, the use of a finger grip interconnected with the firearm mounted illumination device mitigates the need to readjust grip during operations.

These and other advantages will be apparent from the disclosure of the inventions contained herein. The above-described embodiments, objectives, and configurations are neither complete nor exhaustive. As will be appreciated, other embodiments of the invention are possible using, alone or in combination, one or more of the features set forth above or described in detail below. Further, this Summary is neither intended nor should it be construed as being representative of the full extent and scope of the present invention. The present invention is set forth in various levels of detail in this Summary, as well as in the attached drawings and the detailed description below, and no limitation as to the scope of the present invention is intended to either the inclusion or non-inclusion of elements, components, etc. in this Summary. Additional aspects of the present invention will become more readily apparent from the detailed description, particularly when taken together with the drawings, and the claims provided herein.
