- Four-bend body armor plates are provided that can include a chest bend, two wither bends, and a central line bend.
- Methods for manufacturing a body armor plate are provided that can include individually providing a chest bend, a central line bend, and two wither bends within the plate itself using the same stamp assembly.
- The body armor plates and manufacturing methods will be described with reference to
FIGS. 1-16 . Referring first toFIG. 1 , abody armor plate 10 is shown that depicts one side, or the frontal surface, of the body armor plate. This body armor plate can be utilized in conjunction with a fabric vest as desirable, and according to example implementations, the body armor plate hangs more comfortably than the prior art plates. - Referring to
FIG. 2 , the opposing surface or interior surface of the body armor plate is shown that includesbend partitions chest bend 12, acenter bend 14, and two wither orside bends 16. - Referring next to
FIGS. 3-6 , views of the body armor plate according to the present disclosure are provided from every side as the body armor plate is supported. Particularly,body armor plate 10 hasbends bend 12. As can be seen, thebends 16 are to be aligned upon the withers of the person utilizing the body armor plate and 12 is to extend at least proportionately about the chest area of the person wearing the body armor plate. - Referring next to
FIG. 7 , abody armor plate 70 is shown in one stage of processing.Body armor plate 70 includes diecasting lines 72 andpoint 76. As can be seen,plate 70 includes an angled portion at the upper portion as well as square or normal portions at the lower right and left portions. According to example configurations, upper casting line can run acrossplate 70 to define an edge of an upper trapezoid portion shared with an edge of a lower rectangle portion.Plate 70 can include side casting lines that run from the ends of upper casting line in a triangular form to a center point of the lower portion atpoint 76. - Referring next to
FIG. 8 , aclassic die press 80 is shown. This diepress 80 includes a couple ofnotch lines 81. These notch lines can be used to line up withlines 72 during the manufacturing process. In accordance with example implementations, the die press can have a 4¾″ radius, and the die can be 6″ wide, and about 8½″ long. The twoalignment marks 81 are at 2″ and 4″, about the width of the die cast. The body armor plate can typically be about ¼″ thick to 5 mm thick, also up to ½″ thick, in other embodiments the thickness can be 0.125, 0.210, or up to 0.250 inches thick. The plate itself can be 8″×10″, 10″×12″, or 11″×14″ for example. The sheets themselves can be made of AR500 steel with a hardness greater than 500 but less than 520, and AR550 steel with a hardness greater than 550, and in the 5 mm designs, the hardness can be greater than 610, for example. - Referring to
FIG. 9 one notch line is shown lined up with one of the two side casting lines for example. Referring toFIG. 10 , as can be seen, one of the notch lines can be aligned with one of the lines in this particular embodiment and the press activated to bend the body armor. As can be seen, the line can be side casting line and the notch aligned with same to create a bend inFIG. 11 . The plate can then be moved to the other side of the press, and the other side casting line can be aligned with theopposing notch 81, and bent as shown inFIGS. 12 and 13 to create a dual bend as shown inFIG. 14 . Referring next toFIGS. 15 and 16 , to create the chest bend, the upper casting line can be aligned directly between the two notch points, and the press activated to create the chest bend as shown inFIGS. 15 and 16 . Upon completion of preparing the bends in the body armor, the body armor can be shot blasted to clean up residual particulates in the manufacturing process, cleansed with an organic solvent such as acetone, for example, dried, and then an adhesive primer applied thereto, and then a polyurea coating applied thereto. - In compliance with the statute, embodiments of the invention have been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the entire invention is not limited to the specific features and/or embodiments shown and/or described, since the disclosed embodiments comprise forms of putting the invention into effect.
