Multiple plate ballistic shield with ballistic layering

Abstract

A ballistic shield may include multiple ballistic plates. The first plate may be smaller contain a handle and viewport and be able to connect to a second plate. The second plate shall be able to connect to the first plate and when combined, can create a larger shield using only the handle and viewport of the first plate. Other plates may be connected to the second plate to increase the ballistic coverage required. A rotating plate can be connected with a hinge and spacer. When dropped the rotating plate would enable extended coverage. When the rotating plate is rotated upward, an additional layer of ballistic coverage is provided.

Claims

1. A ballistic shield selectively deployable in a first configuration or a second configuration comprising a first protective portion including a first protective component and a second component detachably attached to each other and a second protective portion selectively rotatably between a first position and second position hingedly coupled to said second component of said protective portion such that when said ballistic shield is in said first configuration said first protective component is detached from said second component said first protective shields the head and neck of a person holding said ballistic shield in front of the person and when said first protective component and said second component of said first protective portion are assembled to each other and said second protective portion of is in said second position said ballistic shield shields the head, neck and torso of a person holding said ballistic shield in front of the person.

2. The ballistic shield of claim 1 wherein said second component of said first portion and said second portion are in said second configuration, said second component of said first and said second portion are substantially coplanar.

3. The ballistic shield or claim 1 wherein said first protective component and said second component of said first portion are substantially parallel when said ballistic shield is in said second configuration.

DETAILED DESCRIPTION

(9) The invention described with reference to accompanying drawings, has at least one illustrative representation shown. This invention may be illustrated in different morphologies and should not be construed as limited to the representations contained in this document. The illustrations herewith are not limiting as to the scope of the invention.

(10) Terms may be used interchangeably, unless made expressively clear from the text. The terms ballistic panel, plate or ballistic plate shall be used interchangeably unless specifically made distinguishable from the text. The term ballistic shield shall mean a ballistic plate with at least one additional item attached to it. Similarly, the terms hinge and components to enable rotation shall be interchangeable. Some terms such as connector or fastener shall be deemed understandable by someone with proficient skills in this art. Some drawings views may have some items missing from an actual ballistic shield. Not having all items in every drawing view is done for clarity and understanding of the entities on that drawing.

(11) As shown in FIG. 1, a basic ballistic shield assembly comprised of a ballistic plate 1 a viewport 2, a feature to connect to another ballistic plate 3 and handle 6. Each ballistic plate in these embodiments shall be made of material sufficient for the threat level designed to encounter. Also because this is primarily designed to be man portable (carried by hand or on rollers), weight of the ballistic materials is a prime consideration. For National Institute of Justice (NIJ) level 3A and NIJ 3, a polymer based material made of aramid, para-aramid or polypropylene is recommended. However for NIJ4 shields which may be supported by wheels, steel laminate plates with high hardness and ceramic plates are recommended.

(12) FIG. 2 shows the secondary ballistic plate 10 with an additional ballistic plate 20 attached to it. An additional ballistic plate may be attached to the secondary plate for many reasons, such as to use a lighter ballistic material than the secondary plate. The secondary plate has a component or feature 15 to connect the secondary plate to the primary plate. In FIG. 2 the secondary plate only has holes for which bolts can be mounted to fasten the primary plate 1 to the secondary ballistic plate 10. It must be noted that any way to attach the plates such as a quick disconnect track would be acceptable.

(13) FIG. 3 shows the protected (user) side view of the primary ballistic plate 1 attached to the secondary ballistic plate 10. FIG. 3 shows that the primary ballistic plate 1 is connected on center to the secondary ballistic plate 10 such that approximately equal masses of ballistic material lay to the sides of the primary ballistic plate 1. This enables the user easier one handed holding of the handle 6. In addition, the user can use the handle 6 and the viewport 2 for the entire assembly.

(14) FIG. 4 shows a spacer 12 attached to ballistic plate 20 and a hinge 14 attached to both the spacer 12 and a rotating ballistic plate 25. In FIG. 4 the leafs of the hinge are oriented such that the rotating ballistic plate covers the ballistic plate 20 along with the adjoining secondary ballistic plate 10.

(15) In FIG. 5 the rotating ballistic plate is moving downward. FIG. 5 illustrates that the width of the spacer 12 must be sufficient such that collision does not occur between the rotating ballistic plate 25 and ballistic plate(s) 20 or 10.

(16) FIG. 6 shows that when the leafs of the hinge 14 are 180 degrees apart, rotating ballistic plate 25 and ballistic plate 20 (and any ballistic plate attached to ballistic plate 20) which are separated by a spacer 12 and hinge 14, are parallel, but not coplanar. In this orientation maximum ballistic coverage is achieved. It is critical that the rotating ballistic plate 25 extends over the leaf of the hinge which is connected to the spacer. Although not fastened to the leaf connected to the spacer, the extension will provide rigidity with respect to horizontal forces for the ballistic shield when the rotating plate is downward. Also in this configuration there is overlap of ballistic plates 25 and 10 such no gap exists for a horizontal projectile to pass between the plates.

(17) FIG. 7 shows the impact side when the rotating ballistic plate 25 is folded upward to lay parallel with ballistic plates 10 and 20 as in FIG. 4. The viewport 2 is visible through the removal of ballistic material 30 in the rotating plate 25. The viewport 2 is transparent and can be made of NIJ level 3A or 3 or 4 layered polycarbonates or a layered glass, polycarbonate and polyurethane construction. The viewport materials must overlap the rectangular opening in the non-transparent ballistic materials and be bolted to them.

(18) The variable configuration allows the users to increase the resistance of the ballistic protection of just one ballistic plate for higher velocity projectiles. When the rotating ballistic plate 25 is folded upward the maximum ballistic coverage is decreased. The concept of overlapping ballistic plates for increased ballistic protection and the expense of decreased ballistic coverage is called ballistic layering.

(19) The scope of the invention is defined by the following claims and their physical equivalents.
