1. Field of the Invention
The present invention relates generally to portable ballistic barriers. More specifically, the embodiments of the present invention relate to deployable, mobile bunkers that are collapsible for easy storage and transport and may be rapidly deployed when needed.
2. The Relevant Technology
Law enforcement agencies, particularly SWAT teams, are often called upon to confront armed and dangerous individuals. It is not uncommon for these agencies to be facing 30-06 rifle rounds since these are common in hunting. Additionally, criminals have been known to purchase .223 green-tip penetrator rounds which are available for purchase to civilians.
Although it is standard practice for law enforcement to wear body armor, the body armor presently available is heavy and typically only rated for handguns. For example, a National Institute of Justice (NIJ) level IIIA vest's maximum rating is for a limited number of shots from a 44 magnum handgun. Personal body armor material is bulky and heavy, vests weigh approximately 10 pounds. The shape and size of the armor must not interfere with the officer's agility therefore vests are designed to be as small as practical. Consequently, they only cover the vital areas of the body. In general terms, a “bulletproof” vest or other armor will protect personnel from the vast majority of handgun threats. But, there is always a tradeoff between protection, wear-ability and budget constraints. It should be understood that body armor can be defeated by rifle rounds, unusually high velocity pistol ammunition, pistol ammunition fired from a rifle barrel, armor piercing ammunition, sharp-edged or pointed instruments (e.g., knives, ice-picks, arrows, etc.), and/or other unusual ammunition and/or situations.
Also, at some angles, projectiles can slide, or deflect off the edges of armor, or ricochet. Furthermore, projectiles that are successfully stopped by armor will always produce some level of injury, resulting in severe bruising, broken bones, and possibly serious internal injury, even death. Soft body armor defeats most pistol and shotgun projectiles, but no vest makes personnel invulnerable to all threats.
Further, the head is much more susceptible to blunt trauma than the body. Any impact of a bullet on a helmet will cause injury and can cause death. The odds of serious injury are reduced with head protection, but, just as with any armor, no guarantee of invulnerability can be made.
For additional protection (in addition to wearing personal body armor) personal shields may be employed. Personal shields are heavy, so they are designed to only cover the vital areas of the body. Shields provide an additional layer of protection, however, most shields are also only rated for handguns and they hinder the ability of the officer to travel long distances due to their weight (approximately 30 pounds). The ability to manipulate a weapon is also severely limited since at least one of the officer's hands is occupied carrying the shield.
The level of protection required for each confrontation can vary widely. It is not uncommon for an agency to consider the 30-06 and the .223 green-tip penetrator rounds as their most severe threat. Furthermore, to permit adequate observation without unnecessarily exposing personnel, such personnel typically needs to be positioned within a distance of about 30 yards. These requirements have established a baseline of performance that is required if adequate protection for personnel is to be provided.
Currently, there are two rating systems for ballistic protection: 1) Underwriters' laboratory (UL), and 2) The National Institute of Justice, (NIJ). The rating systems are not consistent between the two entities and they do not precisely identify the rating for a 30-06 and/or a .223 green-tip penetrator round. To properly rate a ballistic panel for these particular rounds, it is necessary to have a ballistic panel tested at an approved independent test laboratory for: 1) each specific ammunition type, and 2) the specific target distance.
It would be an advance in the art to provide meaningful protection against 30-06 and/or .223 green-tip penetrator rounds that does not need to be carried by personnel. Law enforcement agencies would find such protection to be quite attractive. Although the following description focuses primarily on the requirements of law enforcement agencies, it should be evident and it has been considered that this invention could be used by various agencies such as, but not limited to: military, secret service, homeland security, etc.
It would also be an advance in the art to provide a collapsible, mobile bunker low-footprint that can easily be stored in the trunk of a car, the rear of an SUV, or in an armored personnel carrier (APC) and that can be readily deployed when needed.
The present embodiments constitute a collapsible, mobile ballistic bunker. The mobile ballistic bunker is a collapsible frame on wheels. In one embodiment, the frame permits the vertical stacking of three ballistic panels that act as a full-body shield or wall. Preferably, the frame is made of a lightweight aluminum and has side channels for receiving ballistic panels in nesting engagement. Each of the ballistic panels is removably insertable into the side channels of the frame and overlaps with the adjacent panel so that ballistic integrity is maintained at the joints. Because the ballistic panels are removably insertable into the frame, the panels can be interchanged if damaged or if a higher or lower ballistic-rated panel is desired. Also, the ballistic panels can be disposed in layers such that an air gap can be provided between layers of ballistic panels. The topmost panel is a vision panel made of ballistic glass. In some embodiments, at least one ballistic panel has integrated handholds for removal of the ballistic panel from an assembled mobile ballistic bunker to be used as a personal ballistic shield. In some embodiments, the ballistic panels weigh less than 50 pounds each. The ballistic panels may be encased in polyurea.
In some embodiments, the mobile ballistic bunker includes a movement assembly for supporting the frame. The movement assembly may comprise any of a number of types of wheels, runners, or rubber track systems, however, caster-type wheels with large run-flat tires that permit the movement of the bunker over rough terrain are preferred. In some embodiments, the wheels rotate 360 degrees and can be locked into an orientation for front to rear or lateral motion.
In a preferred embodiment, the movement assembly has retractable caster-type wheels that are capable of pivoting into a refracted, nesting position for low-footprint storage. The term “low-footprint” as used herein means that the height profile and the girth profile of the overall bunker is minimized to a compact assembly to save storage space and to facilitate transport of the bunker.
Additionally, an apron of ballistic material may be connected to the lowermost panel to extend to the ground. This ballistic apron will reduce the threat of “skip-rounds.”
After being deployed, the mobile ballistic bunker may be collapsed into a storage mode for storage and easy transport. The vision panel is removed from the side channels of the frame. Slide brackets along each side of the frame are moved to permit the ballistic panels to hinge where they overlap so that the wall formed by the panels can be folded in half. With the other panels still positioned between the side channels, spring-lock pins are released from each side of the frame permitting the vertical panels to be rotated to a horizontal disposition. The vision panel can then be nested on top of the folded panels and secured for storage. A Velcro strap can be used to secure the vision panel in its nested disposition.
In some embodiments, the frame is comprised of a plurality of frame sections with side channels and the frame sections/side channels abut end to end forming joints. One set of abutting frame sections is disposed opposite another set of abutting frame sections to define an area into which ballistic panels can be removably inserted into layers of ballistic panels. The opposing side channel sets may be configured to provide for an air gap between layers of ballistic panels. Also the configuration of the layered ballistic panels is such that vertically adjacent ballistic panels overlap at the joint so that ballistic integrity is maintained at the joint.
The embodiments of the present mobile, ballistic bunker invention provide ballistic protection by using interchangeable ballistic panels rated for rifle or handgun depending upon the threat presented. Also, due to the ballistic bunker's rolling mobility, it does not need to be carried into position. Rather, the ballistic bunker can be fully deployed at a safe location remote from the desired position and then rolled into position providing ballistic protection during that movement. Once in position, it is free-standing thereby freeing up both hands of the personnel. Further, the single-wide embodiment can pass through a 3-foot doorway without exposing personnel or compromising its ballistic integrity.
For situations requiring broad ballistic protection, a double-wide embodiment of the mobile, ballistic bunker can be used. Although, for brevity of disclosure, the double-wide embodiment is not shown in the drawings, a person of skill in the art will readily understand how to make and use a double-wide embodiment from the disclosure herein.
The embodiments of this invention have been developed in response to the present state of the art, and in particular, in response to the problems and needs in the art that have not yet been fully solved by currently available body armor and shields.
These and other features of the present invention will become more fully apparent from the following description, or may be learned by the practice of the invention as set forth hereinafter.
In order that the manner in which the above-recited and other features and advantages of the invention are obtained will be readily understood, a more particular description of the invention briefly described above will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. Understanding that these drawings depict only typical embodiments of the invention and are not therefore to be considered to be limiting of its scope, the invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The presently preferred embodiments of the present invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout. It will be readily understood that the components of the present invention, as generally described and illustrated in the figures herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the present invention, as represented in the Figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of presently preferred embodiments of the invention.
The word “exemplary” is used exclusively herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
Preferably, the frame 12 is made of a lightweight aluminum and has side channels 22 for receiving ballistic panels 16 in nesting engagement. The side channels 22 hold the panels 16 in the generally vertical disposition to form the wall 20. Each of the ballistic panels 16 is removably insertable into the side channels 22 of the frame 12 and overlaps with the vertically adjacent panel 16 so that ballistic integrity is maintained at the joints. A portion of the frontal ballistic panels 16 extends above the abutting horizontal joint between vision panel 18 and its adjacent ballistic panel 16 so that it overlaps with the vision panel 18.
The frame 12 may be partially disassembled and is also hinged to be collapsible for storage. The vision panel 18 may be removed (see
In some embodiments, the mobile ballistic bunker 10 includes a movement assembly 32 for supporting the frame 12. The movement assembly 32 may comprise caster-type wheels 14 with large run-flat tires 34 that permit the movement of the bunker 10 over rough terrain. In some embodiments, the wheels 14 rotate 360 degrees and can be locked into an orientation for front to rear or lateral motion.
Additionally, an apron 36 of ballistic material may be connected to the lowermost panel 30 to extend to the ground. This ballistic apron 36 will reduce the threat of “skip-rounds.”
After being deployed, the mobile ballistic bunker 10 may be collapsed into a storage mode for storage and easy transport. The vision panel 18 is removed from the side channels 22 of the frame 12. With the other panels 16 still positioned between the side channels 22, spring-lock pins 38 are released from each side of the frame 12 permitting the vertical panels 16 to be rotated about the pivot axle 31 to a horizontal disposition. Also, the spring-lock pins 38 can be re-engaged to secure the panels 16 in the storage mode, enabling the ballistic bunker to be stored in a horizontal or a vertical disposition, as desired, when in the storage mode. Slide brackets 40 along each side of the frame 12 are moved to permit the ballistic panels 16 to hinge where they overlap so that the wall 20 formed by the panels 16 can be folded in half (see
In some embodiments, handles 42 are provided at various locations to assist with folding, transport, and maneuverability of the ballistic bunker 10. For example, in one embodiment, the middle panel 28 may have a handle 42 to assist with maneuverability of the bunker 10 without exposing the personnel's hands to gunfire (see
In a preferred embodiment, the movement assembly 32 has retractable wheels 14 that can retract to nest within the frame 12 for storage.

In an alternative embodiment, the mobile ballistic bunker 10 includes a movement assembly 32 for supporting the frame 12 that does not have wheel-retraction capability. The movement assembly 32 may comprise caster-type wheels 14 with large run-flat tires 34 that permit the movement of the ballistic bunker 10 over rough terrain, or it may have any other suitable type of wheel, runner, or rubber track system.
Once deployed, the mobile ballistic bunker 10 of this alternative embodiment also may be collapsed into a storage mode for storage and easy transport. The vision panel 18 is removed from the side channels 22 of the frame 12. With the other panels 16 still positioned between the side channels 22, spring-lock pins 38 are released from each side of the frame 12 permitting the vertical panels 16 to be rotated to a horizontal disposition. Slide brackets 40 along each side of the frame 12 are moved to permit the ballistic panels 16 to hinge where they overlap so that the wall 20 formed by the panels 16 can be folded in half. The vision panel 18 can then be nested on top of the folded side channels 22 and secured for storage. A Velcro strap (not shown) can be used to secure the vision panel 18 in its nested disposition. It has also been contemplated with this alternative embodiment that the vision panel 18 could optionally have hinges.
Although this alternative embodiment does not have a vertical storage profile as small as the retractable-wheel embodiments, this alternative embodiment may be less expensive to manufacture and more cost effective for some law enforcement, security, or military units to acquire and use.
