Abstract

The present invention is a flexible, fillable and/or inflatable breach bag with a planar body and at least one fillable bladder for use in breaching locked or barricaded doors or penetrating surfaces with explosive charges. The breach bag may conform to a variety of shapes, depending on the application. The bag generally includes a panel of flexible material having at least two material layers, including a plurality of seams joining at least two of the material layers to form at least one bladder between the material layers for the selective of fill material, generally in the field. The bladders include fluid inlets providing fluid access to said bladder for filling said bladder with fill material. Additionally, the bags include means to suspend the breach bag against structures to be breached.

Claims

1. A bag for use with an explosive charge for use in breaching structures, comprising:

a panel of flexible material having at least two material layers, said panel including a medial spine portion and a plurality of seams joining at least two of said material layers to form at least two segregated bladders between said material layers for the insertion of fill material, said medial spine portion defined by spine seams, and said plurality of seams including upper and lower seams that are each spaced from the edge of said panel material so as to form integral upper and lower strips;

a selectively closeable fluid inlet for each said bladder providing fluid access to each said bladder for filling each said bladder with fill material;

an explosive charge attached to said at least one bladder so as to focus an explosive shock wave, create a concussive force, or create an explosively formed projectile when said explosive charge is detonated; and

deployment means for positioning said bag immediately adjacent a building structure.

2. The bag of claim 1, wherein said deployment means includes at least one grommet disposed proximate an edge of said panel.

3. The bag of claim 2, wherein said grommet is disposed on a material strip defined by a seam and an edge of said panel.

4. The bag of claim 1, wherein said medial spine portion does not include a bladder space for filling with fluid.

5. The bag of claim 1, wherein each of said upper and lower strips includes attachment means.

6. The bag of claim 5, wherein said attachment means comprises grommets.

7. The bag of claim 1, further including a first fastening edge and a second fastening edge having closure means for releasably attaching said first and second fastening edges so as to create a hollow tube between said and second bladders.

8. A breach bag, comprising:

a planar body structure having a front a back a top a bottom a left side and a right side, defining a planar body perimeter;

at least two fillable bladders, each having an interior and an exterior, a front and a back;

said fillable bladder each integrally connected to said planar body structure by bladder seams defining a bladder perimeter within said planar body perimeter;

said fillable bladder seams, isolating each said fillable bladder interior from said planar body structure;

said at least two fillable bladders separated from one another by a spine defined by said bladder seams;

each said fillable bladder having at least one re-sealable capped port incorporated into said fillable bladder exterior, providing a means for filling said fillable bladder;

said planar body structure having a plurality of grommets within said planar body perimeter, providing a means for attachment of said breach bag to a surface; and

an explosive charge attached to said at least one fillable bladder so as to focus an explosive shock wave, create a concussive force, or create an explosively formed projectile when said explosive charge is detonated.

9. The breach bag of claim 8 wherein said planar body structure conforms to a rectangular shape.

10. The breach bag of claim 9 wherein each fillable bladder is located in said planar body structure defined within said planar body perimeter.

11. The breach bag of claim 9 wherein said explosive charge be attached to each said fillable bladder with adhesive material.

12. The breach bag of claim 9 wherein said planar body structure may conform to a folded configuration to create an ovoid wherein explosive material may be placed.

13. The breach bag of claim 9 wherein said left side and said right side of said planar body structure utilize a hook and loop closure system to conform to a folded configuration.
