Definitions
- the invention relates to a bastion. More particularly, the invention relates to a multiple panel-based bastion system, Which can be used, for example, for military applications and force protection.
- bastions has been traditional ever since Roman times. In the seventeenth and eighteenth centuries it took the form of wicker baskets filled with earth or stones. In the early twentieth century, sand bags were used. In the later twentieth century bastions took the form of gabion structures lined with geo-textiles.
- Prior art protection barriers suffer from a number of additional drawbacks. Visual impact of prior art protection barriers is unsuitable for deployment within cities and the systems do not provide any concealment option. Deployment for long periods of time is also problematic given that barriers are exposed to environmental agents such as fungus, and UV attacks, that rapidly deteriorate them. Further, prior art protection barriers require intensive maintenance.
- the present invention seeks to produce a protection barrier or bastion which overcomes the above described prior art drawbacks.
- a protection barrier or bastion according to an exemplary embodiment of the invention includes a multi-cell structure, for example, for military and anti-terrorist use, consisting of structures conformed by welded wire panels lined with knitted wire or expanded mesh, linked together to constitute a fire resistant cell structure. This structure is filled with sand, crushed rock or granular materials and may be camouflaged. Further, the multi-cell structure is deployable in flat or sloped terrain.
- the expanded metal mesh or knitted wire mesh lining may withstand a flame thrower attack successfully, without losing particulate filling material through the openings.
- the expanded metal mesh or knitted wire mesh lining admits rooting of plants, which helps mitigate the visual impact of the bastions in the cities. Given the nature of the mesh, the plants will grow over the bastions, changing the hard appearance to look as natural fences melding them with the landscape.
- the expanded mesh or knitted wire mesh lining materials are more suited to resist environmental attacks and are less maintenance demanding than prior art bastions.
- the wall has a continuous volume, and therefore, behaves like a monolithic rather than an adobe like structure.
- the infill continuity results in cavities or caverns created by impact of projectiles being filled by material coming from both damaged and adjacent cells, thus, improving the protection offered by the bastion.
- the bastion may further include a pinned connection system that allows continuity of cells at different heights, and thus, for the possibility of deployment in sloped terrain.

Any numerical values provided in FIG. 21 (or in any of the other figures or the present specification) are given by way of example, and the invention is not to be construed as being limited thereto.
- FIG. 22 is a highly schematic top plan view showing how external and internal panels interconnect to form a bastion according to the embodiment of FIG. 15 .
- the use of a single column of interdigitated connecting tubes in the external panels 102 and internal panels 104 causes the panels to be closer together at their junctions, reducing the space between adjacent panels, as compared to the embodiment of FIGS. 1-14 .
- the bastion structure becomes tighter and more rigid as a result.
- mesh may be provided on internal panels 128 , typically it may not be used.
- the mesh 118 will be folded back around the end vertical bars of the external panel 102 , as shown in FIG. 22 , to provide a vertically extending flap, that, due to material memory behavior of fiberglass, will tend to bear against the sides of the internal panels 104 , thus creating an automatically deploying flap to provide resistance to leakage of infill material through the junction.
- FIGS. 23-26 illustrate various examples of structures which may be built using the multipanel bastion system of the embodiment of FIGS. 15-22 , though other additional structures may be built as well.
Abstract
A bastion including one or more free-standing structures for use in, for example, military applications and for force protection. The free-standing structures are made up of a plurality of interconnected fire resistant mesh covered wire panels and are filled with, for example, sand, crushed rock or granular materials.
Description
- This application is a continuation-in-part of, and claims priority of the filing date of, U.S. Ser. No. 10/879,678, filed Jun. 29, 2004, and presently pending.
- The invention relates to a bastion. More particularly, the invention relates to a multiple panel-based bastion system, Which can be used, for example, for military applications and force protection.
- The use of bastions has been traditional ever since Roman times. In the seventeenth and eighteenth centuries it took the form of wicker baskets filled with earth or stones. In the early twentieth century, sand bags were used. In the later twentieth century bastions took the form of gabion structures lined with geo-textiles.
- This latter application, was basically the use of elements originally devised for civil works applied to the military use. This structure was rapidly deployable but its main failing was its lack of fire resistance. At best, a fire retardant composite was used in some situations to delay ignition. Use of flame throwers, incendiary bombs, Molotov cocktails and even tracer bullets of machine guns (one every seven in a belt loader) in combat situations destroys the protection afforded by this conventional bastion by igniting its lining or sand bags defenses.
- Prior art protection barriers suffer from a number of additional drawbacks. Visual impact of prior art protection barriers is unsuitable for deployment within cities and the systems do not provide any concealment option. Deployment for long periods of time is also problematic given that barriers are exposed to environmental agents such as fungus, and UV attacks, that rapidly deteriorate them. Further, prior art protection barriers require intensive maintenance.
- The present invention seeks to produce a protection barrier or bastion which overcomes the above described prior art drawbacks.
- A protection barrier or bastion according to an exemplary embodiment of the invention includes a multi-cell structure, for example, for military and anti-terrorist use, consisting of structures conformed by welded wire panels lined with knitted wire or expanded mesh, linked together to constitute a fire resistant cell structure. This structure is filled with sand, crushed rock or granular materials and may be camouflaged. Further, the multi-cell structure is deployable in flat or sloped terrain.
- The expanded metal mesh or knitted wire mesh lining may withstand a flame thrower attack successfully, without losing particulate filling material through the openings. At the same time the expanded metal mesh or knitted wire mesh lining admits rooting of plants, which helps mitigate the visual impact of the bastions in the cities. Given the nature of the mesh, the plants will grow over the bastions, changing the hard appearance to look as natural fences melding them with the landscape.
- The expanded mesh or knitted wire mesh lining materials are more suited to resist environmental attacks and are less maintenance demanding than prior art bastions.
- The wall has a continuous volume, and therefore, behaves like a monolithic rather than an adobe like structure.
- The infill continuity results in cavities or caverns created by impact of projectiles being filled by material coming from both damaged and adjacent cells, thus, improving the protection offered by the bastion.
- The bastion may further include a pinned connection system that allows continuity of cells at different heights, and thus, for the possibility of deployment in sloped terrain.
- To the accomplishment of the above and related objects the invention may be embodied in the form illustrated in the accompanying drawings. Attention is called to the fact, however, that the drawings are illustrative only. Variations are contemplated as being part of the invention, limited only by the scope of the claims.

FIGS. 23-26 illustrate, non-exhaustively, various structures which may be obtained from the multipanel bastion system ofFIGS. 15-22 . - The basic components of an exemplary embodiment of a bastion of the present invention, generally designated 10, are
panels 12 a-12 j. Thepanels 12 a-12 j may be made, for example, from a welded wireframe including wires 14 having, for example, diameters between 3 mm and 8 mm. Thewires 14 may, for example, have a rectangular pattern with center to center distance depending on load, for example, 5 cm to 20 cm. Thewires 14 may be lined with ascreen mesh 16 of expanded metal or wire knitted mesh, stitched to the wire frame or connected usingstaples 18. Alternatively, thepanels 12 a-12 j may be configured without a mesh. However, in this case thewires 14 are spaced close together so as to prevent a filler, used to fill thebastion 10, such as sand crushed rocks, granulars, etc., from spilling out. - In the example embodiment of the present invention illustrated in
FIG. 1 ,exterior panels 12 a-12 h andinterior panels Bastion 10 may be used, for example, as a force protection system for military applications. The length of thebastion 10 may be as long as desired with a minimum of one cell and may extend up to, for example, hundreds of cells. - As best seen in
FIGS. 2A and 2B , which illustrate close-ups of a connecting region between twocells exterior panels sides 4 via pinnedconnection 30.FIG. 2B is the same view as provided inFIG. 2A except a bit closer up and Withpanel 12 g shown disconnected for clarity. Depending on the height of thebastion 10, a pinned connection may require, for example, a set of 4 up to 24 connecting tubes. -
Exterior panels tubes Tube segments correspondent connecting tubes 24 and 26 (FIG. 3 ) connected tointerior panel 12 i by a centeringpin 28 a, which passes through the connectingtubes pin 28 b, which passes through connectingtubes - Centering pins 28 a and 28 b also function also as an anchoring element of the system when staked to the ground.
FIG. 12 is a perspective view of the rightmost cell ofFIG. 1 withpins - As can be seen in
FIG. 2A , connectingtubes bastion 10.Tubes tubes pin 28 a is at least partially hidden behindpanel 12 f.Panels FIG. 3 . The remainingpanels 12 a-12 e are interconnected in an identical manner using pins 28 a-28 m or, alternatively, using straps 32 (FIG. 4 ). - As illustrated in the top view of
FIG. 3 , the lining ormesh 16 of theexterior panels connection 30 is bent asflaps 34 and is used to avoid infill spills through thespace 36 between the connectedexterior panels Flaps 34 may be used to prevent spillage between the connection of the other panels as well. - For observation posts and fire back positions, an insert, such as a
duct 38, may be provided on both interior and exterior panels into which face inserts 40 may be installed.Duct 38 may have an X or Y shape (from a top view) in accordance with the tactical tooth-saw fire pattern.Duct 38 is a rectangular box with a reduced section in amiddle section 42 andfull sections 44 at the faces of the panels. On the outer face of thebastion 10 these face inserts 40 may be covered with a mesh lining (not shown), which both masks theduct 38 and provides protection against objects thrown from outside. At the inner side, aflap gate 46 can be provided, for temperature control.FIG. 11 shows the bastion ofFIG. 1 from a different perspective and without theduct 38. -
Interior panels FIG. 6 ,interior panel 12 i may have connectingtubes 34 at a point between its sides, e.g., in the middle, for connection viapin 28 n to connectingtubes 35 welded to anotherinterior panel 12 k, also without mesh lining. Although not shown,interior panel 12 k may be similarly connected toexterior panel 12 e. Alternatively,interior panel 12 k may be free floating, connected toexterior panel 12 e andinterior panel 12 i by straps, or supported on either side by material used to fill thebastion 10. - Once the structure has been anchored, for example, by anchoring pins 28 a-n used in the pinned
connection 30, an infill of filling material, for example, sand, crushed rock, or granulars is laid in compacted layers conforming a monolithic structure to complete the defense system. Thebastion 10 ofFIGS. 1 and 10 are shown in a partially filled state so as to expose theinterior panels - The pinned connection system of the present invention allows for deployment in sloped terrain, as illustrated in
FIG. 15 , by steppingpanels 12 in the vertical direction, i.e., joining the panels at different heights. -
FIG. 8 illustrates a multi-cell structure filled with sand including twowalls 48, 50 connected by ahexagonal corner unit 52′.Wall 48 includescells 48 a-48 c and wall 50 includes cells 50 a-50 c. As indicated above, the filling of a single cell with two different granulates may be accomplished, for example, by means ofinterior panel 12 k (FIG. 6 ). - In an exemplary embodiment of the present invention, a top mesh-lined
cover panel 54, as illustrated inFIG. 5 , may be pivotally or otherwise connected to a top of any given bastion cell. Thepanel 54 mitigates the action of whirlwinds and drafts caused by nature or machinery. - In an exemplary embodiment of the present invention, as illustrated in
FIG. 12 , thebastion 10 is a multiple height or piled bastion including a base having four columns 56 a-56 d of multi-cell structures, a second row having three columns 58 a-58 c, a third row having twocolumns 60 a and 60 b and a top row having asingle column 62. The panels in each row may be connected to adjacent rows using metallic orplastic straps 32 that align and fasten the layers, as detailed inFIG. 4 .FIG. 4 is a cross section taken along lines 4-4 inFIG. 12 . The multi-cell structures may be piled directly on top of each other or may be separated by astructural element 64, such as a structural beam, flat board, steel deck or plate, as illustrated inFIG. 14 . - In an exemplary embodiment of the present invention, the above mentioned materials constituent of the system, are resistant to fire attacks and tropical conditions, thus allowing for a longer life expectancy, and reutilization of the elements.
- In an exemplary embodiment of the present invention, the screen or
mesh 16 lining allows rooting of vegetation, thus providing camouflage to the system.FIG. 14 illustrates a bastion system of the present invention camouflaged by natural elements, such as vegetation. - In an exemplary embodiment of the present invention, the panel's wire mesh, pinned connections and expanded metal mesh are environmentally resistant to damage like rust, UV, fungus attack, etc., by means of galvanic protection, or polymeric coating.
- In an exemplary embodiment of the present invention, the structure may be used as basic constituent for constructions and fortifications, supporting a roof structure.
- Repairs can be made to the bastion by replacing a damaged
panel 12 or by strapping an overlappingnew panel 66 over an existing damagedpanel 12, as illustrated inFIG. 7 . - As illustrated in the figures, the panels form box shaped structures. However, three or more panels may be joined in the manner taught above to form other shaped free-standing structures having, for example, triangular or hexagonal cross sections when viewed from above. These free-standing structures may then be interconnected, for example using pinned connections or straps, to form bastions of varying shapes and sizes.
-
FIGS. 15-22 illustrate an alternative embodiment of the invention, wherein the internal panels employ only a single vertical row of connecting tubes, on each side of the internal panel. -
FIG. 15 is a perspective view of a partial bastion assembly according to an alternative embodiment of the invention.Partial bastion assembly 100 employsexternal panels 102 andinternal panel 104. -
FIG. 16 is a plan view of a layout for anexternal panel 102 for a bastion according to the embodiment ofFIG. 15 .External panel 102 includes metal bar grid 110 (formed fromhorizontal bars 112, and vertical bars 114), cylindrical connectingtubes 116, andmesh 118. As can be seen inFIG. 16 , the placement of the connectingtubes 116 repeats every thirdhorizontal bar 112, with the vertical spacing between adjacent connecting tubes being slightly greater (to accommodate manufacturing tolerances) than the height of two connecting tubes. -
FIG. 17 is a plan view of a layout for aninternal panel 104 for a bastion according to the embodiment ofFIG. 15 .Internal panel 104 includes metal bar grid 120 (formed fromhorizontal bars 122 and vertical bars 124), and cylindrical connectingtubes 126. Mesh 128 may or may not be provided.Mesh 118 and mesh 128 (if present) may be fabricated as expanded metal mesh. Alternatively, fiberglass mesh (e.g., polyester coated/fused fiberglass) may be employed. It is believed that fiberglass mesh may have benefits that may extend the useful life of bastions constructed therefrom, including being rustproof, having less tendency to leak infill material, following piercing by bullets or shrapnel, being fire-resistant and being less likely to cause injury to persons handling the panels, as may be the case where metal mesh is employed. -
FIGS. 18 and 18A illustrate schematically of how twoexternal panels 102 and aninternal panel 104 may be interconnected, using a single connecting pin (not shown). In embodiments of the invention, corresponding to the embodiment ofFIG. 15 , all connecting tubes for bothexternal panels 102 andinternal panels 104, are all the same length, and external and internal diameters, for ease of manufacturing and interchangeability of components. Because of the selection of vertical spacing, on bothexternal panels 102 andinternal panels 104, equivalent to the height of two connecting tubes, connectingtubes internal panels 104 andexternal panels 102. It may be understood that, in an alternative embodiment of the invention (not shown), by increasing the vertical spacing of the connecting tubes, on the external and internal panels to three connecting tube lengths, it becomes possible to join 4 panels all together, e.g., two external panels and two internal panels, by a single connecting pin. -
FIGS. 19 and 19A illustrate schematically howexternal panels 102 andinternal panels 104 according to the embodiment ofFIG. 15 may be used to create a bastion construction that may be used to ascend or descend contours in geography. -
FIGS. 20 and 20A illustrate schematically how external panels only, according to the embodiment ofFIG. 15 , may be used to create a bastion that may be used to ascend or descend contours in geography. -
FIG. 21 is an illustration showing representative panel structures according to an embodiment of the invention. Any numerical values provided inFIG. 21 (or in any of the other figures or the present specification) are given by way of example, and the invention is not to be construed as being limited thereto. -
FIG. 22 is a highly schematic top plan view showing how external and internal panels interconnect to form a bastion according to the embodiment ofFIG. 15 . The use of a single column of interdigitated connecting tubes in theexternal panels 102 andinternal panels 104 causes the panels to be closer together at their junctions, reducing the space between adjacent panels, as compared to the embodiment ofFIGS. 1-14 . In addition, the bastion structure becomes tighter and more rigid as a result. As mentioned above, while mesh may be provided oninternal panels 128, typically it may not be used. In order to control leakage of infill material, at the, junctions, at the edges, ofexternal panels 102, themesh 118 will be folded back around the end vertical bars of theexternal panel 102, as shown inFIG. 22 , to provide a vertically extending flap, that, due to material memory behavior of fiberglass, will tend to bear against the sides of theinternal panels 104, thus creating an automatically deploying flap to provide resistance to leakage of infill material through the junction. - In embodiments in which mesh is omitted from
internal panels 104, migration of infill material from “cell” to “cell” is facilitated, thus leading to a more monolithic completed bastion structure.FIGS. 23-26 illustrate various examples of structures which may be built using the multipanel bastion system of the embodiment ofFIGS. 15-22 , though other additional structures may be built as well. - As many apparently widely different embodiments of the present invention can be made without departing from the spirit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the appended claims.
