Abstract
A training device is described for perfecting the art of forcibly opening a door in an emergency. The training device has a frame and a door placed in the frame. A dead bolt is mounted in the door and protrudes from the door in a locked position relative to the frame. A vise is attached to the frame. The vise has a movable jaw mounted on a block and a stationary jaw, and means for tightening the movable jaw against the dead bolt. The dead bolt protrudes from the door between the stationary and movable jaw. A method of using the training device causes the door to pivot and the dead bolt to move off of the vise, thus simulating an actual forced opening.
Claims18
A method for learning and perfecting the art of forcibly opening a locked door in an emergency, the method comprising:
- selecting a training device comprising:
- a frame having a header and a rectangular shaped saddle;
- a door placed in the frame, and having a first and a second edge perpendicular to the header and saddle;
- a lock rail attached to the door and having an opening;
- a dead bolt having a proximal end mounted in the door through the opening and a distal end extending out of the first edge in a locked position relative to said frame;
- a surface adjacent to the dead bolt;
- means for tightening the surface against said dead bolt;
- a rod attached to the second edge, the rod having
- an upper and a lower end, the upper end movably mounted to the header and the lower end mounted to the saddle;
- adjacent to said second edge, means for tensioning said door about said dead bolt;
- a grate pivotally mounted to the rectangular shaped saddle;
- and
- two wheels attached to each of the short sides of said rectangular saddle, wherein the two wheels on one of the short sides are each mounted on a swivel to form a caster;
- step for bracing said training device;
- positioning a person adjacent to the first edge and within an arm's length of the door;
- wedging a tool between the frame and said first edge of said door, and above or below the dead bolt;
- securing the tool between said frame and said door by striking its proximal end;
- rotating said tool;
- causing said door to initially pivot about said dead bolt;
- and
- moving said dead bolt off of the surface.

A training device comprising:
- a frame having a header and a rectangular shaped saddle, and two vertical sides;
- a jamb an each vertical side of the frame;
- a door placed in the frame, and having a first and a second edge perpendicular to the header and rectangular shaped saddle;
- a lock rail attached to the door and having a first opening;
- a dead bolt having a proximal end mounted in each door through the first opening, and a distal end protruding from said door in a locked position relative to said frame;
- a rod attached to the second edge and having
- an upper and a lower end, the upper end of each rod movably mounted to the header and the lower end of each rod mounted to the saddle;
- a vise having a movable jaw mounted on a block, and a stationary jaw, the vise attached to the jamb on each vertical side such that the dead bolt is protruding from the door and between the stationary and movable jaw;
- means for tightening said movable jaw against said dead bolt;
- adjacent to said second edge, means for tensioning said door about said dead bolt, wherein the means for tensioning is a coil spring, such that said door initially pivots about said dead bolt as it is being forcibly opened;
- a grate pivotally mounted to said rectangular shaped saddle;
- and
- two wheels attached to each of the short sides of said rectangular saddle, wherein the two wheels on one of the short sides are each mounted on a swivel to form a caster.
