Description

TECHNICAL FIELD

The present invention relates generally to weapon mountable devices, and more particularly to a low profile illumination device for use with a tactical rail.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Many of today's military style rifles incorporate one or more tactical rails (also known as Picatinny rails and Weaver rails), which allow a user to secure a variety of auxiliary items onto the weapon. Many common examples of devices that utilize these rails include: night vision devices, reflex sights, foregrips, bipods, bayonets, laser spotters and other such items. The inclusion of the Picatinny rail enables the weapon to be turned into a multi-functional platform, which can be customized for a particular mission.

U.S. Pat. No. 6,782,652 illustrates one embodiment of a weapon mounted Picatinny rail system and a conventional rail cover. As illustrated in background FIG. 1 the weapon 10 can include a one or more Picatinny rails 13 mounted thereon. The Picatinny rail 13 can be defined as a surface provided for the attachment of weapons and weapons system having a series of alternating teeth 13a and grooves 13b. Rail 13 has a cross section that is hexagonal with two sides, namely the top and the bottom of the hexagon, being longer than the other two sides. Teeth 13a and grooves 13b are formed in the top surface, as shown in FIG. 1. Each of the two side surfaces 13c and 13d define shelves for receiving external hardware via a sliding motion. Because Picatinny rails are common in military weaponry as a surface for attaching scopes and spotters, for example, from many manufacturers, the Picatinny rail, and the use thereof is well-known and well-defined. In the present illustration, a scope 15 is secured onto the uppermost rail 13 of the weapon 10.

In some instances, the rails are not incorporated into the original construction of the weapon, and must be added at a later time. One example of such a weapon rail is shown and described in U.S. Pat. No. 5,590,484 for a Universal Mount for Rifle. As described therein, these rails typically include a flattened bar having a major dimension much greater than its minor dimension and having a series of transverse grooves formed across the top section. The rail typically includes a cross section in the shape of a wide hexagon.

Regardless of the type of rail system, one of the most commonly utilized weapon attachments is the weapon mounted flashlight. One example includes U.S. Pat. No. 6,851,214, to Oz. As shown in background FIG. 2, the conventional system for providing weapon illumination is to secure a flashlight 20 onto the Picatinny rail 13. Although this approach seems logical from a distance, real world use of this arrangement has illustrated several significant drawbacks.

As shown in FIG. 2, the conventional lights 20 incorporate large and heavy flashlights which severely offset the delicate balance of the weapon. By including a heavy bulky object at the end of the weapon, it becomes more difficult for the user to position the weapon in an upright and level orientation for extended periods of time, without suffering from fatigue. Moreover, it is well known that whenever the center mass of a weapon is altered, the accuracy to which the weapon can be utilized, both in terms of aiming and maneuverability is severely affected. In addition to the above, the sheer size and shape of these traditional lights 20 protrude outward from the weapon and affect its streamlined appearance.

Although the shape of the light may seem trivial to the uninitiated, those of skill in the art will recognize that during close quarters combat, a weapon must be able to transition between fighting positions without becoming snagged on clothing and/or obstacles encountered by the weapon holder.

Accordingly, there remains a need for a low profile tactical illumination device that does not suffer from the drawbacks of the devices described above.

SUMMARY OF THE INVENTION

To this end, the inventive concepts disclosed herein can be utilized on any type of weapon system having a standardized tactical rail. Several non-limiting examples include machine guns, handguns, rifles and the like. U.S. Pat. No. 6,782,652 describes a weapon mounted Picatinny rail system cover, and is incorporated herein by reference. Although not illustrated, any number of devices such as locking tabs, for example, can be included with the device to prevent movement along the rail during use.

Identical reference numerals are used for like elements of the invention or elements of like function. For the sake of clarity, only those reference numerals are shown in the individual figures which are necessary for the description of the respective figure. For purposes of this description, the terms “upper,” “bottom,” “right,” “left,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the invention as oriented in FIG. 3.

FIG. 3 illustrates one embodiment of a low profile tactical illumination device 30 that is useful for understanding the inventive concepts disclosed herein. As shown, the device 30 can include a lightweight hardened main body 31, a plurality of illumination devices 35, one or more control switches 36 and a power source 37 that are in communication via a plurality of internal wires (not illustrated).

The main body 31 can act to securely position each of the elements 35-37 into a compact unit suitable for the rigors of combat. Additionally, the body 31 itself can take any number of distinct shapes, and can be constructed from any number of known materials and methods. In one preferred embodiment, body 31 can be constructed from an extremely lightweight material such as injection molded plastic having a plurality of internal connectors (not shown) for securely positioning each of the elements 35-37. Of course, any number of other materials such as steel and aluminum, for example, can also be utilized.

The main body 31 can include a top surface 31a having a removable battery cover 31a1, a bottom surface 31b, opposing side surfaces 31c-31d, a front side surface 31e and a back side surface 31f. In one preferred embodiment, each corner/transition 31g between surface areas will be rounded so as to avoid any sharp angles/edges which could snag onto clothing and the like.

The bottom surface 31b can further include a centrally located curved/concave portion 32 extending from the front side surface 31e to the back side surface 31f. The concave portion having a pair of opposing rail grips 32a and 32b positioned therein. The concave portion 32 will include an overall dimension that is complementary to the dimension of a standard Picatinny rail, and grips 32a and 32b being positioned within the concave surface so as to allow the device to slide onto and off of the rail 13 via the shelves 13c and 13d.

As shown, a plurality of light emitting devices 35 can be secured within the main body so as to project illumination in a forward direction. To this end, the light emitting devices 35 can preferably be positioned along the front surface 31e, but can also be positioned along any surface 31a-31f and oriented so as to project the light forward (i.e., beyond the front surface 31e).

In one preferred embodiment, each of the lights 35 can include Light Emitting Diodes (LED's) capable of providing extremely high luminous intensity while drawing very little power as compared with conventional incandescent bulbs. Of course, any number of other illumination devices such as incandescent, Xenon, florescent, and high intensity discharge lights, among others can also be utilized herein.

The device 30 can also include one or more optional and non-traditional light emitting devices 35a (See FIG. 4). Several suitable examples include Infrared lights, laser pointers and/or stunning illuminators. As defined herein, a stunning illuminator can include any lighting instrument which can function as a less than lethal mechanism by providing an intense short burst of extremely bright light capable of momentarily blinding/stunning an opponent. One suitable example is described in U.S. Pat. No. 7,866,082, to Eisenberg, the contents of which are incorporated herein by reference. Each of these devices is well known in the art, and can be in communication with the power source 39 and the controller 36.

The device can also include one or more controllers 36 in order to accept user inputs and provide operating instructions to the lights 35. In one preferred embodiment, the controller 36 can include a conventional button/switch located on the top surface 31a of the main body that is capable of transitioning the device between an “off” and “on” position. Of course the controller can also include any number of multi-function switches capable of operating each of the lighting elements 35 and/or 35a independently from each other.

In one preferred embodiment, the power source 37 can include one or more DC batteries capable of providing the necessary power requirements to each element of the device 30. The power source being in communication with each of the lighting elements 35 and the controller 36. Although illustrated with regard to circular batteries located along the top surface of the device, this is for illustrative purposes only, as those of skill in the art will recognize that any number of individual batteries ranging from NICAD, NiMH, Alkaline, lithium and rechargeable, among others, can be utilized herein and located within any portion of the device without deviating from the scope of the inventive concepts disclosed herein.

FIG. 4 illustrates an alternate embodiment of the device 30 that further includes a remotely mountable controller 46 and a recharging port 47.

The remotely mountable controller 46 can allow a user to control the operation of the device 30 from a location other than the device main body. In one preferred embodiment, the controller 46 can include a conventional pressure activated on/off switch 46a that is connected to the device via a connecting wire 46b. An attachment unit 47 can be secured to the back of the switch 46a so as to allow the switch to be removably secured to the weapon at a location of the user preference. As described herein, attachment unit 47 can preferably include opposing strips of hook and loop material, each having an adhesive surface for mounting to the switch and weapon. Of course, other known products for securing the switch to the weapon in a removable manner are also contemplated. Although not illustrated, in one alternate embodiment, the switch 46b can be permanently secured to the weapon via any number of known adhesive materials and/or compression fittings such as screws, for example.

The recharging port 47 can act as an interface for allowing any number of installed rechargeable batteries to receive a charge via a conventional DC battery charger. These devices are well known in the art, and no further description will be provided herein.

FIG. 5 illustrates one embodiment of the device 30 in operation. As shown, the device 30 can be mounted onto the existing Picatinny rail 13 of a weapon 10. When so positioned, the streamlined and lightweight design of the device can function to provide illumination without adversely affecting the weight of the weapon, nor presenting a bulky surface area that is likely to snag during close quarters combat. Moreover, when mounted onto the grip 10a of the weapon, the remotely mountable switch 46a can operate the device without requiring the user to remove either hand from the weapon at any time. To this end, the switch can be positioned along the surface area normally gripped by a user so as to only require a squeeze to turn the lighting elements 35 and/or 35a into an “on” or “off” position.

As described herein, one or more elements of the low profile tactical illumination device 30 can be secured together utilizing any number of known attachment means such as, for example, screws, glue, compression fittings and welds, among others, depending upon the construction materials and manufacturing processes utilized.

As to a further description of the manner and use of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
