Abstract

An armor system, comprising at least two elements, wherein the elements are arranged at an angle, characterized wherein the at least two elements include a plurality of perforations.

First claim

The invention claimed is:

1. An armor system, comprising:
a rigid frame formed from a top wall, a bottom wall, and two side walls; and
at least two elongate armor plates that each have an elongate axis, wherein said elongate armor plates are arranged inside said rigid frame and in a chevron pattern at a non-zero angle (α)° with respect to one another and with said elongate axes of said elongate armor plates arranged substantially parallel with respect to one another, wherein said at least two elongate armor plates comprise a plurality of perforations and further wherein each of said elongate armor plates provides an outermost surface of the armor system;
wherein the armor system is a removable appliqué system,
wherein the at least two elongate armor plates are fixed with respect to each other, and
wherein the armor system comprises a plurality of sets of said at least two elongate armor plates constructed and arranged in a repeating arrangement.

2. An armor system according to claim 1 , wherein perforations of said elongate armor plates have a shortest dimension which is less than a diameter of a primary threat projectile.

3. An armor system according to claim 1 , wherein perforations of said elongate armor plates have a cross sectioned shape selected from circular, square, elliptical, and a slot.

4. An armor system according to claim 1 , wherein perforations of said elongate armor plates have a beveled edge, so as to provide different cross section size on a front face and rear face of said at least two elongate armor elements.

5. An armor system according to claim 1 , wherein each perforation has a longest dimension, and the distance between each perforation is at least one half of the length of said longest dimension.

6. An armor system according to claim 1 , wherein the perforations are filled with a potting compound.

7. An armor system according to claim 1 , wherein there is provided an IR reflective coating on at least one of the at least two elongate armor plates.

8. An armor system according to claim 1 , wherein one or more elongate armor plates are independently removable.

9. An armor system according to claim 1 , wherein the at least two elongate armor plates are arranged, such that the elongate axis is substantially parallel with respect to a ground plane, upon which a vehicle wheel base is located thereon.

10. An armor system according to claim 1 , wherein the elongate armor plates are assembled in said frame at a non-zero V-shaped angle between 40 degrees and 130 degrees with respect to one another.

11. An armor system according to claim 1 , wherein the at least two elongate armor plates abut each other along a longest dimension of each elongate armor plate, so as to form a repeating arrangement of the at least two elongate armor plates.

12. An armor assembly comprising:
a rigid frame formed from a top wall, a bottom wall, and two side walls, the rigid frame arranged to be attached to a vehicle; and
at least two elongate armor plates that each have an elongate axis, wherein said elongate armor plates are arranged inside said rigid frame and in a chevron pattern at a non-zero angle (α)° with respect to one another and with said elongate axes of said elongate armor plates arranged substantially parallel with respect to one another, wherein each of said elongate armor plates provides an outermost surface of the armor system;
wherein each of the plurality of armor plates comprises a plurality of apertures therethrough,
wherein the armor assembly is a removable appliqué system,
wherein the at least two elongate armor plates are fixed with respect to each other, and
wherein the armor assembly comprises a plurality of sets of said at least two elongate armor plates constructed and arranged in a repeating arrangement.

13. An armor assembly according to claim 12 , wherein the frame defines a frame plane, where each of the plurality of armor plates has a longitudinal axis and is releasably mountable to the frame so that each longitudinal axis may be orientated substantially parallel to the frame plane.

14. An armor assembly according to claim 13 , wherein the frame has four walls including a top wall, a bottom wall and two side walls extending between the top and bottom walls; and
wherein the top wall comprises top guides and the bottom wall comprises bottom guides, and the top and bottom guides are arranged so that each of the plurality of armor plates is releasably mountable in both a top guide and a bottom guide.

15. An armor assembly according to claim 13 , wherein the plurality of armor plates may be orientated so that each armor plate is adjacent to at least one other armor plate.

16. An armor assembly according to claim 15 , wherein the frame has four walls including a top wall, a bottom wall and two side walls extending between the top and bottom walls; and
wherein the top wall comprises top guides and the bottom wall comprises bottom guides, and the top and bottom guides are arranged so that each of the plurality of armor plates is releasably mountable in both a top guide and a bottom guide.

17. An armor assembly according to claim 15 , wherein each of the plurality of armor plates has a face, and the plurality of armor plates may be orientated so that the face of each armor plate is perpendicular to the face of the at least one other armor plate.

18. An armor assembly according to claim 17 , wherein the frame has four walls including a top wall, a bottom wall and two side walls extending between the top and bottom walls; and
wherein the top wall comprises top guides and the bottom wall comprises bottom guides, and the top and bottom guides are arranged so that each of the plurality of armor plates is releasably mountable in both a top guide and a bottom guide.

19. An armor assembly according to claim 12 , wherein the frame has four walls including a top wall, a bottom wall and two side walls extending between the top and bottom walls; and
wherein the top wall comprises top guides and the bottom wall comprises bottom guides, and the top and bottom guides are arranged so that each of the plurality of armor plates is releasably mountable in both a top guide and a bottom guide.

20. An armor assembly according to claim 19 , wherein the top guides are top slots in the top wall and the bottom guides are bottom slots in the bottom wall, wherein each of the slots is arranged to receive one of the plurality of armor plates.
