Portable Security Shield for Roll-Up Door Rotary Latch

摘要

A latching mechanism on a roll-up door in a closed position is protected by a portable shield. The shield, in combination with a floor and the roll-up door protects the latching mechanism from direct impact. The shield is locked into place by a bolt that is positioned below a hub of the latching mechanism. An extension of the shield fits into an opening in the floor or a blocking member in the floor. The bolt is positioned in such a way in the shield that when the shield is in its engaged position the bolt can move only either perpendicular to the door and/or it can rotate about an axis substantially perpendicular to the door. The bolt may be a separate bolt or it may be part of a lock. A kit containing a shield is also provided.
