Abstract

A mobile reconfigurable barricade having a plurality of cells comprised of multiple sheets of deformable barricading fabric. The deformable fabric permits one or more of the cells to collapse to create a bent or reconfigured barricade.

Claims

1. A reconfigurable mobile barricade, comprising:

a primary cell having an anterior portion, wherein the primary cell includes a plurality of vertically oriented primary cell walls comprising deformable barricading fabric with one of the plurality of primary cell walls being a connecting side wall with a connecting edge and another of the plurality of primary cell walls being a coupling side wall with a coupling edge, and wherein the anterior portion is engaged to and extends between the connecting edge and the coupling edge;

a first cell comprising a plurality of vertically oriented first cell walls comprising deformable barricading fabric with one of the plurality of first cell walls being a first side wall;

a second cell comprising a plurality of vertically oriented second cell walls comprising deformable barricading fabric with one of the plurality of second cell walls being a second side wall; and

wherein the connecting side wall is engaged to the first side wall and the coupling side wall is engaged to the second side wall to define an elongated barrier structure, and further wherein, as a result of the deformable barricading fabric, the anterior portion can be collapsed when the connecting edge and the coupling edge are encouraged towards each other to cause the elongated barrier structure to occupy, via the first cell, a first longitudinal axis extending in a first direction and, via the second cell, a second longitudinal axis extending in a second direction different than the first direction.

2. The barricade of claim 1, wherein the primary cell has a primary width, the first cell has a first width, the second cell has a second width, and the elongated barrier has a width no greater than any of the primary, first, and second widths.

3. The barricade of claim 1, wherein the connecting side wall and the first side wall are formed from a signal sheet of barricading fabric.

4. The barricade of claim 1, wherein the deformable barricading fabric comprises a geotextile.

5. The barricade of claim 1, wherein the primary, first, and second cells are formed from multiple sheets of barricading fabric.

6. The barricade of claim 5, wherein one of the multiple sheets of barricading fabric is a first sheet defining a first exterior side, a second of the multiple sheets of barricading fabric is a second sheet defining a second exterior side, and a third of the multiple sheets of barricading fabric is a third sheet defining an interior divider coupled to and extending between the first and second exterior sides, wherein the first, second, and third sheets in combination form the primary, first, and second cells, and further wherein the first and second exterior sides have a height and the interior divider has a height less than the height of the first and second exterior sides.

7. The barricade of claim 1, wherein each of the primary, first, and second cells comprise a triangular shape.

8. An adaptable protective barrier, comprising:

a first triangular compartment comprising a first base wall, a first exterior wall, and a first interior wall, each of the first base wall, the first exterior wall, and the first interior wall comprise collapsible barrier fabric, wherein the first triangular compartment has a first orientation and a first apex defined by a first intersection between the first interior wall and the first exterior wall;

a central triangular compartment comprising a central base wall, a proximal wall, and a distal wall, wherein each of the central base wall, the proximal wall, and the distal wall comprise collapsible barrier fabric, wherein the central triangular compartment has a central orientation opposite the first orientation, and further wherein the central base wall has a distal end connected to the distal wall and a proximal end connected to the proximal wall;

a second triangular compartment comprising a second base wall, a second exterior wall, and a second interior wall, wherein each of the second base wall, the second exterior wall, and the second interior wall comprise collapsible barrier fabric, wherein the second triangular compartment has the first orientation and a second apex defined by a second intersection between the second interior wall and the second exterior wall; and

wherein the first interior wall engages the proximal wall, the proximal end engages the first apex, the second interior wall engages the distal wall, and the distal end engages the second apex, and further wherein the collapsible barrier fabric of the central base wall can be collapsed to cause the first triangular compartment and the second triangular compartment to pivot relative to the central triangular compartment.

9. The barrier of claim 8, wherein the central, first, and second triangular compartments are formed from multiple sheets of collapsible barrier fabric.

10. The barrier of claim 9, wherein the multiple sheets of collapsible barrier fabric are mechanically fastened together to form the central, first, and second triangular compartments.

11. The barrier of claim 8, wherein the collapsible barrier fabric comprises a geotextile.

12. The barrier of claim 8, wherein the collapsible barrier fabric is camouflaged.

13. The barrier of claim 8, wherein the first and second base walls are formed from a first sheet of collapsible barrier fabric, the central base wall is formed from a second sheet of collapsible barrier fabric, and the first exterior wall, the first interior wall, the proximal wall, the distal wall, the second exterior wall, and the second interior wall are formed from a third sheet of collapsible barrier fabric, and further wherein the first and second sheets of collapsible barrier fabric have a height and the third sheet of collapsible barrier fabric has a height less than the height of the first and second sheets of collapsible barrier fabric.

14. A method of reconfiguring a protective barrier, comprising:

providing a protective barrier having a first end portion with a first end and a second end portion with a second end, the first end portion aligned along a first axis, the second end portion aligned along a second axis, the protective barrier further comprising a plurality of contiguous cells and each of the plurality of contiguous cells comprises barrier fabric and a cell volume, and further wherein the protective barrier has a length defined between the first end and the second end and a maximum length when the first and second axes are axially aligned; and

collapsing at least one of the plurality of contiguous cells to reduce the volume of the at least one of the plurality of contiguous cells to cause the length of the protective barrier to be less than the maximum length and to cause the first and second axes to be axially misaligned.

15. The method of claim 14, wherein the barrier fabric comprises a geotextile.

16. The method of claim 14, wherein the barrier fabric comprises a camouflage pattern.

17. The method of claim 14, wherein each of the plurality of contiguous cells has a triangular shape.

18. The method of claim 14, wherein each of the plurality of contiguous cells has a rectangular shape.

19. The method of claim 14, further comprising:

filling at least one of the plurality of contiguous cells with a particulate fill material.

20. The method of claim 14, wherein the plurality of contiguous cells are formed from multiple sheets of barrier fabric.
