Abstract
A guard assembly is used near a doorway with an overhead door on a platform having at least one post mounted adjacent the doorway. The assembly preferably comprises a barrier adapted to extend across the doorway and having at least one coupling which is adapted to connect to a respective post to allow the barrier to block the doorway; and a bracket adapted to facilitate connection and disconnection between the barrier and the overhead door. Such an assembly allows the barrier to block the doorway whether connected to or disconnected from the door and to move with the door as the door opens and closes.
