[0020] Referring now to the Figures, an embodiment of a portable ballistic-resistant device 30 in accordance with the present disclosure as shown in FIGS. 1 and 2. As shown, ballistic-resistant device 30 may include a first ballistic-resistant panel 32, a second ballistic-resistant panel 42, and an engagement portion 50 disposed therebetween that flexibly attaches first ballistic-resistant panel 32 to second ballistic-resistant panel 42. As shown, first ballistic-resistant panel 32 includes an elongated top edge 34, an elongated bottom edge 38 that is substantially parallel thereto, and a pair of side edges 36 that extend between the top edge 34 and bottom edge 38, so that first-ballistic resistant panel 32 is substantially rectangular. In the present embodiment, second ballistic-panel 42 is similarly shaped to first ballistic-resistant panel 32 and includes an elongated top edge 44, an elongated bottom edge 48 that is substantially parallel thereto, and a pair of substantially parallel side edges 46 that extend therebetween. Ballistic-resistant device 30 is configured for use with barriers, such as those shown in FIGS. 9A-9C, that are either entirely or partially incapable of being considered ballistic-resistant because they have open pass-through areas and/or areas constructed of materials that are incapable of stopping projectiles meeting at least the level I standard of Underwriter Laboratories (UL) § 752.

[0021] First ballistic-resistant panel 32 and second ballistic-resistant panel 42 are preferably formed of a material that meets the UL § 752 standards for projectile threat levels I through III, such as, but not limited to, materials as disclosed in U.S. Pat. No. 9,409,607, issued Aug. 9, 2016 to Impact Guard LLC, the entire disclosure of which is incorporated herein by reference, and similar materials. Some example materials are manufactured by Impact Guard LLC, Leetsdale, Pa., and available under product line serial numbers IG4000 and IG6000, respectively, which are comprised of unidirectional fiberglass/polypropylene tapes that are alternatingly stacked at 90° to each other and melt laminated to a solid board. Such materials meet even higher UL § 752 threat level standards, and may be used in alternate embodiments. As well, first ballistic-resistant panel 32 and second ballistic-resistant panel 42 are preferably formed of a fiber-reinforced thermoplastic composite and, more specifically, a polyolefin thermoplastic composite, that is moldable into a rigid or semi-rigid condition. For example, the fiber-reinforced thermoplastic composite may include multiple layers that are bonded to each other, with each alternating layer including a plurality of unidirectional fibers that is substantially parallel to the pluralities of unidirectional fibers in the adjacent layers. As well, in alternate embodiments, first and second ballistic-resistant panels 32 and 42 may be constructed of a flexible ballistic-resistant material, such as a woven material, that is used independently or, in the alternative, adhered to a semi-rigid or rigid base layer that is moldable.

[0022] As best seen in FIG. 2, engagement portion 50 flexibly connects first ballistic-resistant panel 32 to second ballistic-resistant panel 42 so that ballistic-resistant device 30 may be utilized with a crowd control barrier 10a, as shown in FIGS. 3A and 3B, to provide protection to personnel from airborne projectiles. As shown, engagement portion 50 includes an elongated flexible strap 52 that is substantially the same length as the top edges 34 and 44 of first and second ballistic-resistant panels 32 and 42, as shown in FIG. 1. Each side edge 53 of elongated strap 52 includes a pair of substantially parallel flanges 54 that form an elongated recess 56 therebetween. The distance separating each pair of corresponding flanges 54 is substantially the same as the thickness (t) of the ballistic-resistant panel 32, 42 whose corresponding top edge 34, 44 is received therein. Each elongated top edge 34 and 44 of first ballistic-resistant panel 32 and second ballistic-resistant panel 42, respectively, is secured within the elongated groove 56 of flexible strap 52 by means an adhesive and/or a plurality of fasteners, such as, but not limited to, rivets, nuts and bolts, etc., that extend through a corresponding pair of flanges 54 and the material of the corresponding ballistic-resistant panel received therebetween. As shown, engagement portion 50 may be formed of a flexible woven or knitted fiber webbing material that is co-molded within a flexible plastic material. Engagement portion 50 may be formed of any flexible material that is suitable for being affixed to first and second ballistic-resistant panels 32 and 42, and need not be co-molded within a flexible plastic material.

[0023] As best seen in FIGS. 3A and 3B, the dimensions and flexibility of engagement portion 50 are such that engagement portion 50 of ballistic-resistant device 30 is positionably adjacent a horizontal top edge of a corresponding crowd control barrier 10a (FIG. 9A) such that first ballistic-resistant panel 32 and second ballistic-resistant panel 42 are disposed substantially vertically with regard to a vertical portion 12 of crowd control barrier 10a, as well as substantially parallel to each other. As shown, ballistic-resistant panels 32 and 42 do not cover the entirety of the vertical portion 14 of the crowd control barrier 10a. However, ballistic-resistant panels 32 and 42 may be sized such that they overlap the horizontal edges 36 and 46 of ballistic-resistant devices 30 or adjacent crowd control barriers 10a overlap, thereby minimizing potential passthrough areas. In alternate embodiments, multiple engagement portions 50 may be disposed along the lengths of elongated top edges 34 and 44 rather than a single, continuous engagement portion 50 as shown.

[0024] Referring now to FIG. 4A, an alternate embodiment of a ballistic-resistant device 60 includes a single ballistic-resistant panel 62 with an elongated top edge that is molded into an engagement portion in the form of a curved flange 64. As shown, in FIG. 5, curved flange 64 is configured to receive horizontal top edge 14 of a corresponding crowd control barrier 10a therein so that ballistic-resistant panel 62 is vertically disposed adjacent vertical portion 12 of the barrier. As shown, curved flange 64 allow ballistic-resistant panel 62 to be disposed on either side of vertical portion 12 of the corresponding barrier, dependent upon the side of the barrier from which airborne projectiles can be expected.

[0025] Referring additionally to FIG. 4B, yet another embodiment of a ballistic-resistant device 70 includes a ballistic-resistant panel 72 having an engagement portion in the form of an L-shaped flange 71 formed by a top wall 73 that is substantially perpendicular to ballistic-resistant panel 72, and a side wall 74 extending downwardly therefrom that is substantially parallel to ballistic-resistant panel 72.

[0026] Referring now to FIG. 6, an alternate embodiment of a ballistic-resistant device 80 includes a single ballistic-resistant panel 82 that is substantially rectangular in shape, having one or more counterweights 86 affixed to the top edge of the ballistic-resistant panel 82 by flexible straps 84. As shown, a pair of counterweights 86 is affixed by individual straps 84. Alternately, a single elongated counterweight may be affixed by either a single elongated strap or multiple individual straps. Referring additionally to FIG. 7, the counterweights 86 allow single ballistic-resistant panel 82 to be positioned vertically on the side of the barrier 10a from which airborne projectiles may be expected.

[0027] Referring now to FIG. 8, an alternate embodiment of a ballistic-resistant device 90 includes a first ballistic-resistant panel 92 and a second ballistic-resistant panel 94 whose top edges are joined at an apex 94, so that an acute angle is formed therebetween. As shown, ballistic-resistant device 90 is formed of a moldable ballistic-resistant material so that ballistic-resistant device 90 is substantially rigid, thereby allowing it to be used independently of the corresponding crowd control barrier. Preferably, an elongated base flange 96 extends along the bottom edge of both first and second ballistic-resistant panels 92 and 94, to lend improved stability to the stand-alone ballistic-resistant device 90. Elongated flanges 96 may also include apertures therein to facilitate securing ballistic-resistant device 90 in place with ground spikes (not shown) or similar devices.

[0028] In addition to a gate-style crowd control barrier 10a as previously discussed, embodiments of ballistic-resistant devices in accordance with the present disclosure may also be utilized with molded plastic barriers 10b, as shown in FIG. 9B, retractable belt style stanchion barriers 10c, as shown in FIG. 9C, etc. Moreover, ballistic-resistant barriers in accordance with the present disclosure may also be utilized with permanently installed fencing such as, but not limited to, wrought iron fencing, chain-link fencing, etc.

[0029] While one or more preferred embodiments of the invention are described above, it should be appreciated by those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit thereof. For example, alternate embodiments of ballistic-resistant assemblies in accordance with the present disclosure may have fewer, or more, ballistic-resistant panels than the number of the discussed embodiments. It is intended that the present invention cover such modifications and variations as come within the scope and spirit of the appended claims and their equivalents.
