<p>A blast-resistant door latching system features independently attachable but interconnected inner panic bar and outer handle means for opening the door. The latches are biased to the closed position by a travel bar means. The latches are opened when the travel bar means is moved upward by intermediate linkages connecting it to the panic bar and the outer handle. Upward movement of the travel bar is blocked by an inertial stop means when a blast occurs.</p> |
