- This application is a U.S. Non-Provisional patent application which claims priority to U.S. Provisional Patent Application No. 61/562,759, filed on Nov. 22, 2011 and titled “Ballistic Shield Device,” which is hereby incorporated by reference in its entirety.
- A potentially dangerous situation for law enforcement officers is when they approach a vehicle in the process of interrogating a driver suspected of a routine traffic violation. There are a number of cases where the occupant of the vehicle shoots a firearm at the officer, striking him or her in the face or chest. Shields exist that an officer may use to help protect against such an attack. However, these shields are often not practical for an officer to use because they are too heavy and do not provide the protection required by law enforcement personnel.
- The present application discloses a lightweight ballistic shield device comprising a composite material that meets or exceeds National Institute of Justice (NIJ) III-A ballistic protection standards and provides ballistic protection at point blank range. In certain embodiments, the ballistic shield device comprises a composite material having multiple layers of a fabric material laminated together with an adhesive disposed between each layer of the fabric material. A first thermoplastic film is laminated to a top surface of the composite material and a second thermoplastic film is laminated to a bottom surface of the composite material.
- The ballistic shield device of the present application may be formed in a variety of ways. For example, the ballistic shield device may be formed as a ballistic clipboard. In certain embodiments, the ballistic clipboard comprises a composite material, an edge trim attached to the periphery of the composite material, and a clip attached to a top surface of the composite material. The composite material comprises multiple layers of a fabric material laminated together with an adhesive disposed between each layer of the fabric material. A first thermoplastic film is laminated to the top surface of the composite material and a second thermoplastic film is laminated to the bottom surface of the composite material. The edge trim extends between the top and bottom surfaces of the composite material.
- These and additional embodiments will become apparent in the course of the following detailed description.

FIG. 1 illustrates acomposite material 100 of a shield device according to an embodiment of the present application. As shown, thecomposite material 100 comprises a core having multiple layers offabric material 102 laminated together with adhesive 108 to provide desired bullet-resistant properties. Thecomposite material 100 is sealed on the top and bottom with one or more layers ofthermoplastic film 104. In certain embodiments, thecomposite material 100 is between about ¼ inch and about ½ inch thick and has an areal density between about 1.1 psf and about 1.5 psf. - The
fabric material 102 may be a variety of woven or non-woven fabrics, such as, for example, woven or non-woven aramid, fiberglass, innegra, or polystrand fabrics. In certain embodiments, thefabric material 102 is a woven aramid fabric. One example of a fabric material that may be used is Kevlar 29 style 745 fabric having a denier of 3000, plain weave, and 17×17 thread count. In one embodiment, this fabric is about 24 mils (0.61 mm) thick and has a breaking strength of about 1600 lbf/in (length direction) and about 1800 lbf/in (width direction). Further, thefabric material 102 may be selected based on the specific strength and stiffness characteristics of the material. - The adhesive 108 of the
composite material 100 bonds the layers of thefabric material 102 together and also bonds the fibers of the fabric material together. Theadhesive 108 may be a variety of thermoplastic and/or thermoset adhesive agents, such as, for example, polyethylene, polypropylene, or polyurethane based adhesives. In certain embodiments, the adhesive 108 is a thermoplastic film that is polyurethane based. One example of an adhesive that may be used is Nolax (Collano Adhesives) S22.2031 having a density of about 100 grams/m2. - The
composite material 100 may be configured or arranged in a variety of ways such that the shield device meets a specific threat, compliance, or aesthetic. For example, the fibers of thefabric material 102 may be orientated at different angles within a particular layer and/or as between different layers of thecomposite material 100. In certain embodiments, two or more fibers of thefabric material 102 may be orientated at different angles relative to a longitudinal axis of the fabric material, e.g., at 0, 45, 90, or 135 degrees. Further, thecomposite material 100 may comprise alternating layers of a first fabric material and a second fabric material. The type, fiber orientation, weave, weight, denier, thread count, breaking strength, density and/or other property of the first fabric material may differ from the second fabric material. - For example, in certain embodiments, the fibers of the first fabric material may be orientated at either a first angle or a second angle relative to a longitudinal axis of the first fabric material and the fibers of the second fabric material may be orientated at either a third angle or a fourth angle relative to a longitudinal axis of the second fabric material. The first and second angles may be different than the third and fourth angles. For example, the first and second angles may be about 0 degrees and about 90 degrees, respectively, and the third and fourth angles may be about 45 degrees and about 135 degrees, respectively. Alternating the first and second fabric materials throughout the
composite material 100 provides a desired flexibility and rigidity to the shield device in a given direction. For example, alternating the first and second fabric materials may increase the stiffness of a rectangular shaped shield device at or near the corners of the shield device, especially for larger shield devices. - Further, the composition and/or properties of the layers of
fabric material 102 may be tuned such that the shield device meets specific threat or compliance requirements. For example, the type of fabric material and/or the fiber orientation, weave, weight, denier, thread count, breaking strength, density and/or other property of the fabric material may be selected such that the shield device meets specific threat or compliance requirements. Further, the composition and/or properties of thefabric material 102 may change throughout thecomposite material 100, such as, by alternating layers of fabric material having different compositions or properties, placing a block of multiple layers of fabric material having a first composition on top of a block of multiple layers of fabric material having a second composition that is different than the first composition, etc. - The composition and/or properties of the
adhesive 108 may also be tuned such that the shield device meets specific threat or compliance requirements. For example, the type of adhesive and/or the weight, density, film thickness, and/or amount of adhesive may be selected such that the shield device meets specific threat or compliance requirements. Further, the composition and/or properties of theadhesive 108 may change throughout thecomposite material 100, such as, for example, by alternating layers of adhesive having different compositions and/or properties between the layers offabric material 102. Altering the composition and/or properties of theadhesive 108 generally changes the bond strength of the adhesive, which in turns affects the rigidity of thecomposite material 100 and inter laminar bond strength between the layers of thefabric material 102, both of which are related to the stopping ability and deformation characteristics of the shield device. Further, the composition and/or properties of theadhesive 108 may be matched with the fiber construction of thefabric material 102. By selecting the appropriate combination of fibers and adhesives, such as, for example, by selecting the number of layers and/or the type of fiber or adhesive material, the ballistic properties of the shield device may be tuned to meet specific requirements. - The one or more layers of
thermoplastic film 104 may be laminated to one or more surfaces of thecomposite material 100, such as, for example, to the top surface, bottom surface and/or sides of the composite material. Thethermoplastic film 104 may comprise a variety of thermoplastic materials, such as, for example, polypropylene, polyurethane, or polyethylene. In certain embodiments, thethermoplastic film 104 comprises a layer of polypropylene on the top and bottom surfaces of thecomposite material 100. The polypropylene film may be less than 0.02 inch thick or even less than 0.01 inch thick. One example of a thermoplastic film that may be used is an 8 mil polypropylene film made by Crown Films. - The
thermoplastic film 104 seals the core of thecomposite material 100 and may be selected to provide an aesthetic, ergonomic, and/or wear-resistant surface of the shield device. For example, thethermoplastic film 104 may provide an appealing and substantially smooth surface that may be used as a writing surface. Further, thethermoplastic film 104 may provide an exterior coating that protects thecomposite material 100 from UV light, water, moisture, etc. Thethermoplastic film 104 also melts or softens when impacted by a high speed projectile such as a bullet, which permits thecomposite material 100 to “grab” projectiles that impact the material and prohibits the projectile from deflecting off the shield device due to the material's “stickiness” caused by the impact. - During lamination of the
composite material 100, uniform heat and pressure are used to simultaneously bond thethermoplastic film 104 and layers offabric material 102 together in a single consolidation step. As such, this process permits the incorporation of different fabric materials, weaves, and thermoplastics in various combinations such that the ballistic properties of the shield device may be tuned to meet specific requirements, such as a specific threat, compliance, or aesthetic. Further, this process permits the shield device to be formed in a variety of shapes and sizes. For example, the shield device may be configured in various shield forms, as a protective insert, concealed protection, or the like. -

Thethermoplastic film 204 is a polypropylene film that is less than 0.01 inch thick, or about 0.008 inch thick. One exemplary thermoplastic film is an 8 mil polypropylene film made by Crown Films. The polypropylene film provides an appealing and substantially smooth surface that may be used as a writing surface for the shield device. Further, the polypropylene film provides an exterior coating that seals and protects thecomposite material 200 from UV light, water, moisture, etc. The polypropylene film also melts or softens when impacted by a high speed projectile such as a bullet, which permits thecomposite material 200 to “grab” projectiles that impact the material and prohibits the projectile from deflecting off the shield device. - As illustrated in
FIG. 2 , thecomposite material 200 is about ⅜ inch thick and has an areal density of about 1.3 psf. During lamination of thecomposite material 200, temperatures between about 265 degrees F. and 300 degrees F. and pressures between about 100 psi and 300 psi are controlled to provide the desired performance. As discussed below, thecomposite material 200 meets or exceeds NIJ III-A ballistic protection standards and provides ballistic protection at point blank range. - The composite material of the present application may also comprise an optional edge trim to provide desired tactile features to the shield device. For example, as illustrated in
FIG. 2 , thecomposite material 200 includes anoptional edge trim 206. The edge trim may be a variety of shapes, configurations, thicknesses, and/or durometers. For example, the edge trim may be rounded, squared, smooth, or textured. Further, the edge trim may be secured to the layers of fabric material and/or the thermoplastic film in a variety of ways, such as, for example, with a friction fit, adhesive, or fasteners. Further, the edge trim may be made of a variety of materials, such as, for example, natural rubber, plastic, or ethylene propylene diene monomer (EPDM) rubber. -
FIGS. 3A-3H illustrate a shield device formed as a ballistic clipboard ornotepad 300 according to an embodiment of the present application. Theballistic clipboard 300 comprises a unitary piece of thecomposite material 200 with thethermoplastic film 204 laminated to the top and bottom surfaces of the composite material as described above. However, any composite material of the present application may used to form the clipboard. As shown, theclipboard 300 is about 12″ by about 13″ in size and weighs between about 1.7 and 2.0 lbs, or less than 2.0 lbs. - The
clipboard 300 comprises aclip 308. Theclip 308 may be a variety of clips configured to hold a notepad or ticket pad. As shown, theclip 308 is a low-profile clip for retaining papers and documents. Theclipboard 300 may also include an integrated clip for securing an identification card or other information. Further, theclipboard 300 comprisesedge trim 306 attached to the periphery of thecomposite material 200. Theedge trim 306 extends between the top and bottom surfaces of thecomposite material 200. - The
clipboard 300 may also include a handle. As illustrated inFIGS. 3A , 3F, and 3G, thecomposite material 200 comprises an opening or cutout that forms ahandle 302 of theballistic clipboard 300. Theedge trim 306 is placed around the opening or cutout to provide comfort to the user of theclipboard 300. However, theballistic clipboard 300 may include a variety of other openings and/or features attached or otherwise secured to the composite material to facilitate holding, carrying, and/or use of theclipboard 300. Further, thehandle 302 and/or theclip 308 may be arranged such that theclipboard 300 can be used by right or left handed users. - It should be understood that the composite material of the present application may be used to form variety of different shield devices, both user-carried and permanently fixed. For example, the composite material may be formed as a small tactical shield, large shield for critical engagements, vehicle armor including doors, and structures both permanent and temporary. In each of these embodiments, the same basic architecture of the composite material may be used while the plan form is scaled accordingly.
- The shield device of the present application may also be formed and/or concealed in such a manner that the ballistic performance is unobtrusive to others. As such, the shield device is more readily accessible to the user thereby increasing its usefulness. For example, as described above, the shield device may be formed as a clipboard, integrated ticket pad, and/or notepad with the writing surface providing the ballistic protection. As such, the clipboard is not readily distinguishable as a protection aid and thus does not draw undue attention or speculation.
- The shield device of the present application may include one or more handles that permit the user to carry and/or wield the device. The configuration of the handle, such as its size and shape, will vary depending on the specific use of the shield device. For example, smaller shield devices may have no handles and may be entirely convex. Larger shield devices may be formed with an integrated handle cutout and may include edge trim around the cutout. Larger shield devices may also include a handle attached to the shield device to permit proper leverage when the user is wielding the larger device.
- The shield device of the present application may include a variety of devices that may be used by an officer. For example, as illustrated in
FIG. 4 , theballistic clipboard 400 may include a stun orflash device 410 attached or integrated into the back side of the clipboard to illuminate a suspect during routine violations and/or provide a stun effect when necessary. Thedevice 410 may be incendiary in nature or a bright strobe. For example, thedevice 410 may release a pyrotechnic device that would direct a flash with or without an explosion directly at the assailant. This could be a spray of incendiary material or a blast that would project directly toward the assailant. Thedevice 410 may be activated by the user (i.e., the person carrying the shield device) or by the impact of a bullet or strike of a projectile. Depending on the final use of the shield device, other devices may also be included. - The shield device of the present application is also constructed such that it will not shatter or fracture when subjected to blunt force, such as, for example, when struck by someone's hand or with an object such as a rock, bat, bottle, etc. In this regard, the device may be used in crowd control or as a riot shield, restraint, or even as an offensive weapon should the situation arise. Further, because the device does not shatter or fracture when subjected to a blunt force, the user of the device is protected from cuts and abrasions.
