Definitions
- This application relates to a construction of podiums, more particularly podiums having portions with Anti-Ballistic (e.g. “Ballistic Resistant”) properties.
- Anti-Ballistic e.g. “Ballistic Resistant”
- “Bullet Resistant” is the process of making something capable of stopping a bullet or similar high velocity projectiles e.g. shrapnel.
- the term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location.
- Bullet designs vary widely, not only according to the particular firearm used (e.g. a 9 ⁇ 19 mm Parabellum caliber hollow point handgun cartridge will have inferior penetration power compared to a 7.62 ⁇ 39 mm assault rifle cartridge), but also within individual cartridge designs.
- Bullet-resistant materials also called ballistic materials or, equivalently, Anti-Ballistic materials
- Ballistic materials are usually rigid, but may be supple. They may be complex, such as KEVLAR® LEXAN®, and carbon fiber composite materials, or they may be basic and simple, such as steel or titanium. Bullet resistant materials are often used in law enforcement and military applications, to protect personnel from death or serious injuries.
- Anti-Ballistic mobile defense structures or barriers should blend into a conventional room's appearance, where people gather such as meeting rooms, classrooms, libraries, or cafeterias and avoid the rooms taking on the appearance of military bunkers.
- New materials and improvements of manufacturing processes may allow items such as ballistic-proof panels integrated into furniture, moveable barriers and mobile defense structure to become a practical item.
- bullet-resistant vests have been constructed by applying multiple layers of fabric woven from an aramid fiber together, which is sold by Du Pont under the Trademark KEVLAR. It can be used in a flexible state or laminated in a more rigid configuration. The success of the product is attained by multiple layers of the semi-impregnable flexible structure. This material combines high penetration resistance with lightness and flexibility but no one has endeavored to manufacture usable panels for inclusion in rolling structures or movable barriers, wall paneling, cubical dividers, or office furniture items using these materials.
- Example implementations of the present application may include an Anti-Ballistic podium.
- the Anti-Ballistic podium may include a front wall, a first side wall extending at first angle to the front wall, and a second side wall extending a second angle to the front wall. Further, the front wall, the first side wall, and the second side wall define an interior volume, and at least one of the front wall, the first side wall, and the second side wall may include an anti-ballistic structure.
- the Anti-Ballistic structure may include a first structural layer, a second structural layer, a first Anti-Ballistic layer disposed between the first structural layer and the second structural layer; and a second Anti-Ballistic layer disposed between the second structural layer and the first Anti-Ballistic layer.
- the Anti-Ballistic structure may include a first structural layer, a second structural layer,
- first Anti-Ballistic layer disposed between the first structural layer and the second structural layer; and a second Anti-Ballistic layer disposed between the second structural layer and the first Anti-Ballistic layer.
- the Anti-Ballistic core portions of the Anti-Ballistic Panels may be fabricated using not only Aramid fibers and KEVLAR® from DuPont, but also polyethylene fibers and GOLD SHIELD®, which is a KEVLAR® based material, and SPECTRA SHIELD®, which is polyethylene based material, both available commercially from Honeywell.
- GOLD SHIELD® and SPECTRA SHIELD® are high strength synthetic fibers impregnated in partially cured resin for use in ballistic material.
- both of the Honeywell materials can be used as layered soft armor as well as hard armor when they are autoclaved or compression molded into Anti-Ballistic components for construction of the Anti-Ballistic Panels.

Abstract
Description
- This application relates to a construction of podiums, more particularly podiums having portions with Anti-Ballistic (e.g. “Ballistic Resistant”) properties.
- “Bullet Resistant” is the process of making something capable of stopping a bullet or similar high velocity projectiles e.g. shrapnel. The term bullet resistance is often preferred because few, if any, practical materials provide complete protection against all types of bullets, or multiple hits in the same location. Bullet designs vary widely, not only according to the particular firearm used (e.g. a 9×19 mm Parabellum caliber hollow point handgun cartridge will have inferior penetration power compared to a 7.62×39 mm assault rifle cartridge), but also within individual cartridge designs. As a result, while some so-called “bullet-proof” panels may successfully prevent penetration by standard 7.62×39 mm bullets containing lead cores, the same panels may easily be defeated by 7.62×39 mm armor piercing bullets containing hardened steel penetrators.
- Bullet-resistant materials, also called ballistic materials or, equivalently, Anti-Ballistic materials, are usually rigid, but may be supple. They may be complex, such as KEVLAR® LEXAN®, and carbon fiber composite materials, or they may be basic and simple, such as steel or titanium. Bullet resistant materials are often used in law enforcement and military applications, to protect personnel from death or serious injuries.
- There is a growing need for methods of self-protection in an increasingly wide variety of locations. In the modern world, crimes and attacks committed by persons with guns are an ever more common occurrence. In the past, police personnel and military personnel have been the primary targets of gunfire, which has been directed toward them during work or duty. Because of this continual risk of harm, bullet resistant vests and shields have been developed which may be deployed or worn on the user's body as a protective component of their work attire. Such devices, when employed for protection against weapons fire have worked fairly well in preventing a high velocity bullet or shell from penetrating the wearer's body since the velocity is slowed considerably.
- It has been made evident by recent shootings, such as Fort Hood, there may be a need for additional means of self-protection. This mass shooting took place on Nov. 5, 2009, at Fort Hood, the most populous U.S. military installation in the world, located just outside Killeen, Tex. In the course of the shooting, a single gunman killed 13 people and wounded 29 others. According to witnesses, some individuals attempted to stop the shooter, either by charging him or throwing a chair at him, but were mortally wounded in the process.
- It was additionally made evident at Columbine High School in Colorado in 1999 that similar occurrences may also occur in other locations where civilians, including children may be affected and there is an increased need for self-protection. Anti-Ballistic mobile defense structures or barriers should blend into a conventional room's appearance, where people gather such as meeting rooms, classrooms, libraries, or cafeterias and avoid the rooms taking on the appearance of military bunkers.
- New materials and improvements of manufacturing processes may allow items such as ballistic-proof panels integrated into furniture, moveable barriers and mobile defense structure to become a practical item. Previously, bullet-resistant vests have been constructed by applying multiple layers of fabric woven from an aramid fiber together, which is sold by Du Pont under the Trademark KEVLAR. It can be used in a flexible state or laminated in a more rigid configuration. The success of the product is attained by multiple layers of the semi-impregnable flexible structure. This material combines high penetration resistance with lightness and flexibility but no one has endeavored to manufacture usable panels for inclusion in rolling structures or movable barriers, wall paneling, cubical dividers, or office furniture items using these materials.
- As should be understood that embodiments of the present application are not limited to the details of construction and to the arrangement of the components or the steps set forth in the following description or illustrated in the drawings. The various alternatives or combinations of the features shown or described herein may be incorporated into other embodiments and practiced and carried out in various ways, which might be apparent to those skilled in the art once the information herein is reviewed. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description, and should not be regarded as limiting in any fashion. As such, those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing other furniture type ballistic shields or other defense structures for carrying out the several purposes of the present disclosed device and method. It is important, therefore, that the embodiments, objects, and claims herein, be regarded as including such equivalent construction and methodology insofar as they do not depart from the spirit and scope of the present invention.
- Example implementations of the present application may include an Anti-Ballistic podium. The Anti-Ballistic podium may include a front wall, a first side wall extending at first angle to the front wall, and a second side wall extending a second angle to the front wall. Further, the front wall, the first side wall, and the second side wall define an interior volume, and at least one of the front wall, the first side wall, and the second side wall may include an anti-ballistic structure. The Anti-Ballistic structure may include a first structural layer, a second structural layer, a first Anti-Ballistic layer disposed between the first structural layer and the second structural layer; and a second Anti-Ballistic layer disposed between the second structural layer and the first Anti-Ballistic layer.
- Another example implementation of the present application may include an Anti-Ballistic structure for use in a movable or stationary defense structure. The Anti-Ballistic structure may include a first structural layer, a second structural layer,
- a first Anti-Ballistic layer disposed between the first structural layer and the second structural layer; and a second Anti-Ballistic layer disposed between the second structural layer and the first Anti-Ballistic layer.
- Additionally, the Anti-Ballistic core portions of the Anti-Ballistic Panels may be fabricated using not only Aramid fibers and KEVLAR® from DuPont, but also polyethylene fibers and GOLD SHIELD®, which is a KEVLAR® based material, and SPECTRA SHIELD®, which is polyethylene based material, both available commercially from Honeywell. GOLD SHIELD® and SPECTRA SHIELD® are high strength synthetic fibers impregnated in partially cured resin for use in ballistic material.
- Moreover, both of the Honeywell materials can be used as layered soft armor as well as hard armor when they are autoclaved or compression molded into Anti-Ballistic components for construction of the Anti-Ballistic Panels. Other similar materials of like purpose and function are also anticipated by this disclosure.
- Other aspects of implementations of the present application may be discussed or may become apparent in view of the following description of embodiments of the present application and the figures enclosed with this application. In this respect, it is to be understood that the design is not limited in its application to the details of construction and to the arrangement of the components set forth in the following description or illustrated in the drawings.

FIGS. 1-6 illustrate various views of anAnti-Ballistic Podium 100 according to example implementations of the present application. Specifically,FIGS. 1, 3 and 5 are top views of anAnti-Ballistic Podium 100 from various angles. Further,FIG. 2 is a back view,FIG. 4 is a side view, andFIG. 6 is a front view of theAnti-Ballistic Podium 100. As illustrated, the Anti-Ballistic Podium 100 includes atop wall 105 forming a support surface for supporting a variety of items placed on the podium, such papers, books, speaker notes, computing devices, beverages, or any other item that may be apparent to a person of ordinary skill in the art. In some example implementations, thetop wall 105 may be angled toward a speaker to improve a viewing angle. Additionally, in some example implementations, thetop wall 105 may include aridge 110 at one end to prevent documents or other items from sliding off. - The
Anti-Ballistic Podium 100 may also include vertical sidewalls to support thetop wall 105. In the example implementation illustrated inFIGS. 1-6 , thetop wall 105 may be supported by aleft wall 115, aright wall 120 and afront wall 125. As used in this document, directions “right” and “left” are oriented based on the perspective of a speaker standing behind the Anti-Ballistic Podium 100 (e.g., “right” refers to the “right side of a speaker” and “left” refers to the “left side of a speaker”). However, example implementations are not limited to this configuration and other configurations or orientations may be apparent to a person of ordinary skill in the art. - Each of the
top wall 105, leftwall 115,right wall 120, andfront wall 125 may be hallow. The exterior construction of each of thetop wall 105, leftwall 115,right wall 120, andfront wall 125 is not particularly limited and may be any material including but not limited to wood, resin, ceramic, metal or any other construction that may be apparent to a person of ordinary skill in the art. Each of thetop wall 105, leftwall 115,right wall 120 andfront wall 125 may be formed as an Anti-Ballistic structure 200 (illustrated inFIGS. 7-10 below) having a cross-section that may provide anti-ballistic protection may be provided. TheAnti-Ballistic structure 200 is described in greater detail below. - In

Some of thecastors 140 may be rigid castors having a fixed orientation, whileother castors 145 may be swivel rotating castors that are capable of rotating relative to theAnti-Ballistic Podium 100. - Though the
Anti-Ballistic Podium 100 is open on the backside (e.g., a speaker side) as illustrated inFIG. 1-6 , example implementations are not limited to this configuration and in some example implementations, theAnti-Ballistic Podium 100 may be fully closed on the backside. -
FIG. 7 is a cross-sectional view of theAnti-Ballistic Podium 100 ofFIG. 3 taken along line VII-VII′. Again, the backside may include anopen space 135 within which one ormore shelves 180 may be provided. In some example implementations, theshelves 180 may be fixed shelves mounted in theopen space 135 using fasteners, such as screws, nails, bolts, or any other fastener that might be apparent to a person of ordinary skill in the art. In other example implementations, theshelves 180 may be adjustable allowing variable placement within theopen space 135. - Additionally, the
open space 135 may be partially or fully enclosed behinddoors door 130A may be attached to theleft wall 115 by a pair ofhinges 175. In some example implementations, thehinges 175 may be self-closing hinges. Additionally, a lock or latch 170 may be provided to hold thedoor 130A closed and secured shut. In some example implementations, the lock or latch 170 may be magnetic catch. Similarly, thedoor 130B may be attached to theright wall 115 by another pair of hinges similar to thehinges 175 illustrated inFIG. 7 attached todoor 130A. Additionally, another lock or latch, similar to the lock or latch 170, may be provided to hold thedoor 130B closed and secured shut. - Below the
open space 135, a pull-outstep 150 may also be provided in some example implementations. The pull-outstep 150 may include aplatform 155 mounted onsliders 160 to allow theplatform 155 to move linearly relative to thebottom 185 of theAnti-Ballistic Podium 100. In some example implementations, thesliders 160 may be locking sliders that allow theplatform 155 to be locked in an extended (broken-line inFIG. 7 ) or retracted (solid-line inFIG. 7 ) positions. The pull-outstep 150 may also have afloor lock 165 configured to support theplatform 155, along with any person or item resting upon theplatform 155, when the pull-outstep 150 is in the extended (broken-line inFIG. 7 ) position. - Further, in some example implementations, the
Anti-Ballistic Podium 100 may also include rollers orcastors bottom platform 185 of theAnti-Ballistic Podium 100. Some of thecastors 140 may have a fixed orientation, whileother castors 145 may be rotating castors that are capable of rotating to allowing thecastor 145 to rotate relative to theAnti-Ballistic Podium 100. As discussed below with respect toFIG. 10 , in some example implementations,bottom platform 185 may have a cut-out (not shown inFIG. 7 ) configured to receive thefloor lock 165 between thefixed castors 140 at a backside of theAnti-Ballistic Podium 100. - In

As illustrated, thefront wall 125 may be formed as an anti-ballistic structure 200 (illustrated inFIGS. 8-10 below) having a cross-section that may provide Anti-Ballistic protection. TheAnti-Ballistic structure 200 is discussed in greater detail below with respect toFIGS. 8-10 . [0035]FIG. 8 is an enlarged view of a portion (VIII) ofFIG. 7 . InFIG. 8 illustrates a cross-section of thefront wall 125 illustrating theAnti-Ballistic structure 200. As illustrated, oneside 10 of theAnti-Ballistic Panel 200 may be considered an exterior side or active side that may be oriented outward or toward an anticipated ballistic source. For example, theexterior side 10 may be oriented to face out away from a speaker and toward an audience incorporating theAnti-Ballistic structure 200 between an audience and a speaker. Conversely, theother side 20 of theAnti-Ballistic structure 200 may be considered an interior side or passive side that may be oriented inward and away from an anticipated ballistic source. For example, theinterior side 20 may be oriented to face toward a speaker and away from an audience incorporating theAnti-Ballistic Panel 100. - The
Anti-Ballistic structure 200 may include a firststructural layer 205 providing structure and rigidity to thefront wall 125. In some embodiments, the firststructural layer 205 may be formed from wood, polyethylene or any other material that may be apparent to a person of ordinary skill in the art to use for structural support. Further, in some embodiments, the firststructural layer 205 may be formed from compressed wood, “MDF” or medium density fiberboard, plywood or other engineered wood materials that may be apparent to a person of ordinary skill in the art. Such materials may provide an increased resistance to warping and/or fracturing or splintering when hit directly with bullets. In some example implementations, the thickness of the firststructural layer 205 may be, for example, 0.75 inches. However, the thickness is not particularly limited and may be any thickness that may be apparent to a person of ordinary skill in the art. - The
Anti-Ballistic structure 200 may also include a firstelastomeric layer 210 oriented on an exterior side of the firststructural layer 205.

In some example embodiments, the firstelastomeric layer 210 may be a polyethylene foam material (such as a cross-linked polyethylene) or other closed-cell foam material that may be apparent to a person ordinary skill in the art. Further in some embodiments, the firstelastomeric layer 210 may have a thickness of 0.75 inches or thicker. However, embodiments of the present application are not limited to this configuration. - The
Anti-Ballistic structure 200 may also include a first Anti-Ballistic Portion orAnti-Ballistic layer 215 oriented on an exterior side of theelastomeric layer 110. In some embodiments, the firstAnti-Ballistic Portion 215 may be formed from aramid fibers. For example the firstAnti-Ballistic Portion 215 may be formed from plurality layers, each layer being formed from aramid fibers laid parallel to each other. Further, adjacent layers of the firstAnti-Ballistic Portion 215 may be oriented such that the fibers of the adjacent layers are angled with respect to each other. For example, fibers of adjacent layers may form a 90° with respect to each other. In other embodiments, the angle may be an angle other than 90° (e.g. 45°, 60°, 75°, or any other angle that may be apparent to a person of ordinary skill in the art. - It must be fully understood at this time that different Anti-Ballistic materials can be used for the purpose of constructing the first

Moreover, both of the Honeywell materials can be used as layered soft armor as well as hard armor when they are autoclaved or compression molded into Anti-Ballistic components for construction of theAnti-Ballistic Portion 215, as shown and described. Other similar materials of like purpose and function are also anticipated by this disclosure. - In some embodiments, the first
Anti-Ballistic Portion 215 may have a thickness of 0.7 inches. However, embodiments of the present application are not limited to this configuration and may have other configurations that may be apparent to a person of ordinary skill in the art. - The
Anti-Ballistic structure 200 may also include a second Anti-Ballistic Portion orAnti-Ballistic layer 220 oriented on an exterior side of the firstAnti-Ballistic Portion 215. In some example implementations, anadhesive layer 217 may be disposed between the firstAnti-Ballistic Portion 215 and the secondAnti-Ballistic Portion 220. For example, a glue, single part epoxy, or multi-part epoxy may be provided between the firstAnti-Ballistic Portion 215 and the secondAnti-Ballistic Portion 220. - In some embodiments, the second
Anti-Ballistic Portion 220 may be an Anti-Ballistic ceramic material such as silicon carbide materials sold by Saint-Gobain under the trade name “Forceram”. Alternatively, other Anti-Ballistic ceramic materials may be used that might be apparent to a person of ordinary skill in the art. In some embodiments, the secondAnti-Ballistic Portion 220 may have a thickness of 0.3 inches. However, embodiments of the present application are not limited to this configuration and may have other configurations that may be apparent to a person of ordinary skill in the art. - The

However, embodiments of the present application are not limited to this configuration. - The
Anti-Ballistic structure 200 may include a secondstructural layer 230 providing structure and rigidity to thefront wall 125. In some example implementations, anairgap 227 may be located between the secondelastomeric layer 225 and the secondstructural layer 230. In some embodiments, the secondstructural layer 230 may be formed from wood, polyethylene or any other material that may be apparent to a person of ordinary skill in the art to use for structural support. Further, in some embodiments, the secondstructural layer 230 may be formed from compressed wood, “MDF” or medium density fiberboard, plywood or other engineered wood materials that may be apparent to a person of ordinary skill in the art. Such materials may provide an increased resistance to warping and/or fracturing or splintering when hit directly with bullets. In some example implementations, the thickness of the secondstructural layer 230 may be, for example, 0.75 inches. However, the thickness is not particularly limited and may be any thickness that may be apparent to a person of ordinary skill in the art. - In some example implementations, a
