Breaching training door
View Patent ↗A training door for breaching tools has a frame on which the door is hung by hinges at a hinge edge, while at an opposite edge being retained to a jamb by one or more non-shearing bolts. When the door is forced by a breaching tool at the bolt location, the jamb is forced laterally away from the door edge, against rubber mounts that allow limited jamb movement. As the door is forced in (or out, depending on its swing direction), with the jamb spread away somewhat the bolt will bend and fail pulling out of its socket. Replaceable sleeves are secured to the door edge, in several sections of the door to avoid breach tool damage on the door itself.
1. A reusable training door for training the use of breaching tools in forcing open a locked door, comprising:
a door frame, including structure supporting the door frame in an erect, essentially vertical position, and the door frame including, connected together, a threshold horizontal member, a hinge side upright member, an overhead horizontal member and an upright jamb,
a door supported by hinges on the hinge side upright member of the door frame, the door having a hinged edge and a latch edge, and including a bolt lock engaged between the latch edge of the door and the upright jamb of the door frame,
the door frame including rubber mounts at top and bottom ends of the jamb connected to the jamb and the horizontal members and normally retaining the jamb in a normal position with the rubber mounts essentially undeflected and allowing movement of the jamb outwardly away from the latch edge of the door during a breaching operation using a breaching tool, the rubber mounts being positioned to deform elastically to allow the outward movement of the jamb away from the door when sufficient force is applied to the jamb by the breaching tool, and including a fixed stop connected to the door frame at each of top and bottom of the door, limiting outward movement of the jamb to a predefined distance, and
including a removably replaceable protective covering sheath of bend resistant metal secured releaseably to the latch edge of the door to protect the door's latch edge when the breaching tool is engaged to breach the door.
2. The reusable training door of claim 1 , wherein the protective covering sheath comprises a plurality of separate, independent sections of protective metal sheath arranged in tandem, so that individual sections can be replaced as needed when damaged.
3. The reusable training door of claim 2 , wherein three separate sheath sections are included down the height of the door edge.
4. The reusable training door of claim 1 , wherein the protective covering sheath is retained in place at the door edge by a quick-release attachment and extends substantially through the height of the door.
5. The reusable training door of claim 1 , wherein the stop limiting outward movement of the jamb comprises a bracket secured to the overhead horizontal member of the door frame, the bracket being positioned to be engaged by structure connected to the jamb.
6. The reusable training door of claim 1 , wherein the door includes multiple bolt lock points extending between the door edge and the jamb, each of which is capable of receiving a metal bolt which will bend when sufficient force is applied to the door to breach the door.
7. The reusable training door of claim 1 , wherein the fixed stop is positioned to allow outward displacement of the jamb of about 20 to 25 millimeters.
8. The reusable training door of claim 1 , wherein the structure supporting the door in erect position comprises obliquely angled struts secured to the hinge side of the door frame and to the door latch side of the door frame, the struts being obliquely angled relative to vertical, and slots co-acting between the upper end of the door frame and the angled struts to allow adjustment of door orientation to vertical when the door frame is placed on uneven terrain.
9. The reusable training door of claim 1 , further including breaking stick lock points at the top and bottom of the door.
10. The reusable training door of claim 9 , wherein each of the breaking stick lock points comprises, at each of the top and bottom of the door, a pair of adjacent, aligned brackets on the door and the door frame positioned to receive one or more vertically inserted wood stakes, the wood stakes being breakable when the door is successfully breached.
