The present invention claims the benefit of U.S. Provisional Application Ser. No. 60/854,972, filed on Oct. 27, 2006, U.S. Provisional Ser. No. 60/891,880, filed on Feb. 27, 2007, U.S. Provisional No. 60/893,041, filed on Mar. 5, 2007 and U.S. Provisional Ser. No. 60/955,574, filed on Aug. 13, 2007, die entireties of which are hereby incorporated by reference.
FIELD OF THE INVENTIONThe present invention relates generally to the field of portable barriers, and specifically to portable barriers capable of rapid deployment for protecting against vehicular and military style attacks.
BACKGROUND OF THE INVENTIONA barrier device is a structure that is designed to prohibit people, vehicles or other machinery from entering a protected space. The need for barrier devices has increased over the years, especially in view of the increased threat of terrorist attacks on civilian, military and government targets both in the United States and abroad. Moreover, as the technical capabilities, quality of equipment and potency of bombs and other explosive devices employed by terrorists and/or insurgents has increased, so has the need to maintain a more secure, stable, robust and/or larger perimeter around our troops and/or target structures.
A variety of devices have been developed to absorb the kinetic energy generated by the impact of a colliding vehicle. One such structure is the highway barrier. Highway barriers are designed to provide a continuous wall or barrier along the center line of a highway when laid end-to-end to absorb grazing blows from moving vehicles. One commonly used highway barrier is formed of pre-cast reinforced concrete, and is known as the “New Jersey” style barrier. Highway barriers of this type have a relatively wide base including side walls which extend vertically upwardly from the pavement a short distance, then angle inwardly and upwardly to a vertically extending top portion connected to the top wall of the harrier. This design is intended to contact and redirect the wheels of a vehicle in a direction toward the lane of traffic in which the vehicle was originally traveling, instead of the lane of opposing traffic. An example of such a highway barrier is disclosed in U.S. Pat. No. 4,059,362, issued Nov. 22, 1977. Highway barriers, however, are hot specifically designed to absorb a head-on collision from a vehicle or to successfully withstand an explosive attack. Moreover, because highway barriers have a typical weight of about 2,800-3,200 pounds and require special equipment to load, unload and handle, highway barriers are incapable of being rapidly deployed to form a protective perimeter in a short amount of time. Finally, because highway barriers are constructed of concrete, highway barriers will shatter and create dangerous debris during an impact event. Thus, the typical highway barrier does not serve as an adequate shield for personnel because the debris from the highway barrier is equivalent to shrapnel.
While a number of barrier devices have been specifically developed to maintain a safe distance between our troops (and/or target structures) and any suicide bombers either walking or operating a vehicle, existing barrier devices are less than optimal. Existing barrier devices are either: (1) not strong enough; (2) difficult or time consuming to set up; (3) easy to by-pass or destroy; and/or (4) inadequate in preserving an acceptable perimeter.
An example of an existing barrier device is disclosed in U.S. Design Pat. No. 500,859 (“Dehart”), issued Jan. 11, 2005. The Dehart barrier is an assembly of several steel plates stood upright in an opposing orientation and connected to each other by two long poles/rods. The Dehart barrier suffers from a variety of disadvantages. First, the Dehart barrier is a solid unitary structure that is heavy, cumbersome, time consuming and difficult to handle and deploy. As a result, heavy equipment, such as cranes, lifts, or the like are necessary to handle and deploy the Dehart barrier. Second, the Dehart barrier offers little to no protection to people or structures on one side of the barrier from debris, gunfire or other shrapnel that may result from a vehicle or other attack on the opposite side of the barrier. Third, the Dehart barrier device contains no means by which it can be easily connected and secured to another Dehart barrier device or structure to increase the protected perimeter in a stable and robust arrangement.
A second barrier device that exits has been built by Lawrence Livermore of the National Laboratory at the University of California. The Livermore barrier is made for military checkpoints and is a long pipe-like device connected by an ordinary steel cable. The steel cable is secured at each of its end to a separate vehicle which pull the ends of the cable in opposite directions, thereby removing slack from the cable. While the Livermore barrier may be able to stop a terrorist bomber, it does not appear to be capable of deployment in short notice. Moreover, the Livermore barrier suffers from many of the drawbacks set forth above with respect to the Dehart barrier.
Finally, because the Livermore barrier requires that the cable be taut in order to properly work, at least one soldier must be located in each vehicle (at opposite ends of the Cable) in order to make the barrier work. Therefore, you have at least two soldiers exposed to the terrorist vehicle. Additionally, a soldier inspecting a suspect vehicle is still in danger because he/she must be in front of the Livermore barrier.
Thus, a need exists for a more stable, rapidly deployable, robust, and improved barrier system, apparatus, and method.

All of the main components of the barrier device 100 are preferably constructed of steel and are welded together to form an integral structure of the highest strength. However, the other materials can be used, including, without limitation, any metal, metal alloy, or combinations thereof. Additionally, connection between parts can be achieved by whatever means desired, including welding, bolting, screwing, adhesion, etc. The barrier device 100 will last well over 20 years with practically no maintenance. Preferably, the barrier device 100 is coated with a paint or other corrosion resistant material to maintain the integrity of the materials and the connections. Moreover, the barrier device 100 can be easily converted from a rapid deployment device into a permanent barrier with the use of several small key spot welds between adjacent barrier devices and/or proper anchoring.
The barrier device 100 comprises a base plate 10, a wall plate 20, an impact plate 30, an angled support structure 40, a first connector plate 50 and a second connector plate 60. The wall plate 20 is connected to and extends upward from a top surface 11 of the base plate 10 in a substantially perpendicular manner. However, if desired, the wall plate 20 can extend upward from the base plate 10 at an angle. The impact plate 30 is positioned adjacent to and in front of the wall plate 20. As will be described in greater detail below, the impact plate 30 is connected to a front surface 21 of the wall plate 20 and is designed to absorb kinetic energy from a frontal impact event. The angled support structure 40 is connected to a rear surface 22 of the wall plate 20 and the top surface 11 of the baseplate 10. The angled support structure 40 slopes downward from the rear surface 22 of the wall plate 20 to the top surface 11 of the base plate 10 and provides added structural support/integrity to the barrier device 100 during a frontal impact event.
The base plate 10, the wall plate 20, the impact plate 30, the first connector plate 50, the second connector plate 60 and the support structure 40 are formed from steel plates. In one embodiment, the base plate 10 and the wall plate 20 can be formed from ⅜ inch thick AR235 steel. The angled support structure 40 can be formed from ⅜ inch thick AR235 steel. The impact plate 30 can be formed from 3/16 inch thick AR400 steel. The first and second connector plates 50, 60 can be formed from ¼ inch thick AR200 steel. All connections between the plates 10, 20, 30, 40, 50, 60 are achieved by welding. Preferably, an integral and rigid structure is formed. While the invention is not so limited, the barrier device 100 is constructed so that armor piercing rounds can not penetrate through the wall plate 20 during a frontal assault. As a result, the wall plate 20 can also serve as a shield for personnel during firelights in addition to a vehicle barrier.
Furthermore, it is preferred that the barrier device 100 be constructed entirely of metal, metal alloys, or other non brittle materials to minimize the creation of debris resulting from an impact event. Thus, in one embodiment, the barrier device 100 is free of concrete and/or other brittle materials. The total weight of the barrier device 100 is preferably maintained at or below 500 pounds so that it can be easily carried and manually deployed by personnel. In one embodiment, the total weight of the barrier device 100 is between 350 and 400 pounds, and most preferably about 370 pounds. The barrier device 100 can be off loaded from a trailer and setup at a “tactical checkpoint” within minutes upon arriving at the site. It is simple to position and requires only the physical efforts of a few soldiers. There are no tools necessary to deploy or connect multiple barrier devices 100 together.
The base plate 10 is rectangular in shape. The top surface 11 and the opposing bottom surface 12 are substantially planar. The base plate 10 has a perimeter formed by front edge 13, rear edge 14 and side edges 15. A plurality of cut-outs 16 are formed in the base plate 10 near and about its perimeter. The cut-outs 16 form handles 17 that facilitate easy lifting, moving and placement of the barrier device 100. The base plate 10 further comprises a plurality of stake holes 18 for receiving stakes that are driven into the ground. The stake holes 18 are used to secure the barrier device 100 to the ground or other supporting surface.

The wall plate 20 has a substantially vertical orientation (best seen in
The first and second connector plates 50, 60 are connected to the wall plate 20 at or near its first lateral edge 23. The first connector plate 50 is connected to the front surface 21 of the wall plate 20 while the second connector plate 60 is connected to the rear surface of the wall plate 20. The first and second connector plates 50, 60 are rectangular steel plates having opposing planar surfaces. In one embodiment, the first and second connector plates 50, 60 have a rectangular dimension of 8 inches by 20⅛ inches. The invention, however, is in no way limited to any specific dimensions.
The connector plates 50, 60 are attached to the wall plate 20 via welding, bolting, riveting or any other connection means. The connector plates 50, 60 are connected to the front and rear surfaces 21, 22 of the wall plate 20 respectively so that at least a portion of the connector plates 50, 60 extend laterally beyond the first lateral edge 23 of the wall plate 20 in an opposing manner. In other words, at least a portion of the connector plates 50, 60 protrude from the left side of the wall plate 20 and, thus, the barrier device 100 can be attached to an adjacent barrier device 100 to form a barrier wall 200 (shown in
The inwardly facing planar surfaces of the connector plates 50, 60 oppose one another in a spaced relation, thereby forming a space/channel 70 therebetween. The width of the space/channel 70 (which is left to right in
As will be described in detail below, the connector plates 50, 60 of the barrier device 100 are used to slidably receive and engage a portion of the wall plate 20 of an adjacent barrier device 100 when forming a barrier wall 200 (shown in
A plurality of drain holes 19 are also provided in the base plate 10 between the wall plate 20 and the impact plate 30. The drain holes 19 provide a means by which rain water that enters the space between the wall plate 20 and impact plate 30 can escape. This helps reduce corrosion of the structure that may result from stagnant water.

The angled support structure 40 is connected to the barrier device 100 so that the rectangular plate 41 slopes downward from the rear surface 22 of the wall plate 20 to the top surface 11 of the base plate 10. The triangular plates 42 are vertically oriented and are also connected to the rear surface 22 of the wall plate 20 and the top surface 11 of the base plate 10. The connections can be achieved by welding, riveting, bolting or the like. The angled support structure 40 adds structural support/integrity to the barrier device 100 during a frontal impact event.

The first and second interlock structures 325, 326 are substantially J-shaped interlocks. More specifically, the first interlock structure 325 has a J-shaped horizontal cross-sectional profile that forms a vertically oriented channel 327. The second interlock structure 326 also has a J-shaped horizontal cross-sectional profile. However, the horizontal cross-sectional profile of the second interlock structure 326 is a minor image of the horizontal cross-sectional profile of the first interlock structure 325. As a result, the second interlock structure 326 can be slidably inserted downwardly into the vertical channel 327 of the first interlock structure 325 to facilitate a mating relationship (shown in
While the first and second interlock structures 325, 326 are illustrated as being substantially J-shaped, other configurations can be used. For example, a variety of mating cross-sectional shapes, such as generally C-shaped, generally U-shaped, dove-tail, generally L-shaped, or any other type of slidable mating configuration can be used. There is no limitation on the variety and number of cross-sectional shapes that can be used within the scope of the invention. Male and female interlocks can also be used as discussed above.

When the barrier devices 300A, 300B are fully engaged, the extension plates 315B of the second barrier device 300B will slide into and engage the cutouts 314A of the first barrier device 300A. By interlocking the extension plates 315B into the corresponding cutouts 314A, an enormous resistance to shear forces is provided.
For all embodiments of the invention, the recommended deployment configuration during a tactical checkpoint is a “split V formation” beginning at the actual checkpoint and working outward into a larger V. The troops and vehicles, of course will be secured within and behind the barrier wall assuring them of the maximum protection. The “kill zone” will be a designated area in front of the barrier wall (from either angle). The troops and vehicles should be no closer than 50 feet to the actual barrier for maximum protection.

The sniper shield 900 is designed to be lightweight and easily transportable from location to location. It is preferred that the sniper shield 900 weigh between 30 and 40 pounds. Additionally, the sniper shield 900 can be folded in half to facilitate transport. This folding is accomplished via the hinge 940. The hinge 940 is positioned on the rear plate 930. The hinge 930 is centered on the rear plate 930 so that the sniper shield 900 can be folded in half along its centerline. The hinge 930 may be attached to the rear plate 930 in a variety of ways including welding, bolting and the like.
The front impact plate 930 is positioned adjacent to and in front of the rear plate 920. The front impact plate has a planar inner surface 931 and a planar opposing outer surface 932. The inner surface 931 of the front impact plate 930 is connected to connector pipes 902. The connector pipes 902 are in turn connected with the inner surface of the rear wall 920. The connections are preferably welded. The front impact plate 930 is not directly connected with the rear plate 920 because the sniper shield 900 is designed to fold in half for ease of transport. In one embodiment the front impact plate 930 and the rear plate 920 are formed from steel plates. The connector pipes 902 are formed from schedule 40 steel pipe. It is preferred that the sniper shield 900 be free from brittle materials such as concrete.
Both the front impact plate 920 and the rear plate 930 of the sniper shield 900 are physically divided into a left side and a right side. Each side is a mirror image of the other. Between each side is a gap 904. The gap 904 serves to allow for the sniper shield 900 to be folded in half. Preferably the gap is 3/16 inch wide. As best seen in
Depending on the combat circumstances a larger or smaller cutout 903 is preferable, thus the sniper shield 900 may further comprise an adjustable clip 910 positioned over the top of the sniper shield 900 and centered with the cutout 903. The clip 910 can be lowered or raised depending on the needs of the soldier(s) to be protected by the sniper shield 900.
