Patent ID: 7611356

Claim:
A training device, for training emergency personnel to breach a locked door with a blunt force technique, comprising: a door having a front and a rear; a door frame having a first vertical member and a second vertical member, the door hingably attached to the second vertical member, the first vertical member having a latch stop that prevents the door from swinging rearwardly and a latch keep adjacent to the latch stop; a locking mechanism, selectively securing the door and door frame at the first vertical member in the closed position, the locking mechanism having a latching cylinder that is cylindrical in shape with a vertical axis extending substantially parallel to the first vertical member of the door frame, and at least one spring that urges the latching cylinder outwardly against the latch keep to hold the door in a closed position, the spring having sufficient strength such that upon the exercise of an extraordinary blunt force against the door through the exercise of the blunt force technique against the locking mechanism, the latching cylinder is allowed to move sufficiently inwardly to clear the latch stop and allow the door to swing open rearwardly.
