FIGS. 2-3 depict the frame and hinge bar of the embodiment with greater detail. -
FIG. 4 provides additional detail concerning the clamp assemblies of the embodiment. -
FIG. 5 shows positions for placement of explosive charges when using the system. -
FIGS. 1-2 are front and rear isometric views, respectively, of anembodiment 20 of the invention. As used herein, “front” means the side of the invention from which a simulated breach is conducted, and is synonymous with the outside of a door to a structure into which breach is desired. - The
embodiment 20 comprises a durable,reusable frame 22 formed of square tubing and having alock jamb 24 withopposing ends 26, upper and lowerwide members 28 connected at right angles to theopposing ends 26 of thelock jamb 24, and along member 30 havingopposing ends 32 connected to thewide members 28 at right angles. Theframe 22 defines arectangular interior space 34, and may be free-standing or mounted to an existing structure. - A
hinge jamb assembly 36 is slidably attached to thewide members 28 at attachment points and selectively moveable within theinterior space 34 between thelock jamb 24 and thelong member 30 to define adoor space 38 that intersects with theinterior space 34 defined by theframe 22. At any time, the width of thedoor space 38 depends on where thehinge jamb assembly 36 is positioned within theinterior space 34. - The
hinge jamb assembly 36 comprises a cylindrical,elongate member 39 rotatably attached to upper and lowerframe clamp assemblies wide members 28. The upperframe clamp assembly 40 includes aU-shaped clamp body 46 that partially surrounds a section of the upperwide member 28, with the opened end of theclamp body 46 orientated rearward. Theupper clamp assembly 40 also includes a threadedrod 50 with an attachedhandle 52. Theclamp body 46 has a threadedhole 48 through the front side that is aligned with the upperwide member 28 for engagement with the threadedrod 50. The lowerframe clamp assembly 42 includes aU-shaped clamp body 54 that partially encircles a section of the lowerwide member 28. The U-shapedclamp body 54 has threadedhole 56 therethrough aligned with the lowerwide member 28 for engagement with a threadedrod 50. The open end of theclamp body 54 is orientated downward. Theframe clamp assemblies elongate member 39 to saidframe 22. - A
door member 60 has ahinge side 62 attachable to thehinge jamb assembly 36 and alock side 64. Thedoor member 60 is sized to fit in thedoor space 38. Thedoor member 60 is attachable to thehinge jamb assembly 36 with two identicaldoor clamp assemblies 68, each having aU-shaped clamp body 70 connected to apipe segment 72 that encircles theelongate member 39 and a threadedrod 76 attached to ahandle 78. Theclamp bodies 70 have a threadedhole 74 disposed through the front side for receiving the threadedrod 76. Thepipe segment 72 has an interior diameter sized to fit the outer diameter of theelongate member 39. Thepipe segment 72 may be welded to theelongate member 39 or attached using other conventional fastening method. Thedoor clamp assemblies 68 are each door clamp means for selectively fixing saidelongate member 39 to saidhinge side 62 of saiddoor member 60. - A
lock bracket 80 is positioned adjacent to thelock jamb 24. As shown inFIG. 3 , thelock bracket 80 defines anelongate slot 82 intersecting with at least a portion of thedoor space 38, with a portion of theslot 82 being defined by theinterior surface 84 of thelock jamb 24. The sides of thelock bracket 80 are formed from identically-sized front andrear steel plates 86 that extend into thedoor space 38. Thefront plate 86 has a threadedhole 90 that can receive a threadedrod 92, which is attached to ahandle 94. - Use of the embodiment is described initially with reference to
FIG. 1-2 . Initially, the user selects a door member suitable for the desired type of training The selected door member may be, without limitation, a hollow core wood door, a solid core wood door, or a metal door, and the invention contemplates the use of various sizes of door members provided that the door fits within theinterior space 34 defined by theframe 22. The selected door member is positioned within theinterior space 34 and thelock side 64 of the door member 69 is positioned in theslot 82 defined by thelock bracket 80, after which the threadedrod 92 is engaged with thedoor member 60 through the threadedhole 90. Thehinge side 62 of the door member is positioned in the U-shapedclamp bodies 70 ofdoor clamp assemblies 68, and threadedrods 76 are inserted through the threadedholes 74 and tightened to engage thedoor member 60. While the door members are described as having a lock side and a hinge side, suitable door members may have identical sides such that either of the long sides of thedoor member 60 may function as a lock side and either side may function as a hinge side. - The position of the
door member 60 within theinterior space 34 may be adjusted by loosening the upper and lowerframe clamp assemblies wide members 28, sliding thehinge jamb assembly 36 laterally to a new position within theinterior space 34, and then reengaging theframe clamp assemblies wide members 28 to secure thehinge clamp assembly 36 in place. The position of thehinge jamb assembly 36 should be such that thelock side 64 of thedoor member 60 is positioned within theslot 82 and is engagable by the threadedrod 92 through the corresponding threadedhole 90. -
FIG. 4 shows onepossible area 100 on the front surface of thedoor member 60 for placement charges (e.g., pushing or cutting charges) in order to breach the invention proximal to thelock jamb 24 andlock bracket 80. The charges should not come into direct contact with theframe 22 or any of the components engaging thedoor member 60. - After detonation of the charges, the
door member 60 will fracture and be rotatable with thehinge assembly 36. The breacheddoor member 60 may then be quickly replaced by loosening thedoor clamp assemblies 68, removing the damageddoor member 60, and inserting a new door member for the next training sequence. -
FIG. 5 showsalterative areas 102 on the front surface of thedoor member 60 for placement of charges. This configuration incorporates a spacingmember 104 clamped into thelock bracket 80 to allow thelock side 64 of thedoor member 60 to fall free after the charges are triggered. Prior to detonation, thedoor member 60 is held in the door space by thedoor clamp assemblies 68 and frictional engagement of thelock side 64 of thedoor member 60 with the spacingmember 104. After detonation, the spacingmember 104 allows thedoor member 60 to fall freely from the frame when the hinge side of the door member is breached. In this embodiment, the spacingmember 104 is wood. - The present invention is described in terms of a preferred illustrative embodiment of a specifically described system. Those skilled in the art will recognize that alternative constructions of such a system can be used in carrying out the present invention. Other aspects, features, and advantages of the present invention may be obtained from a study of this disclosure and the drawings, along with the appended claims.
