ABSTRACT:
The present invention relates to a shipping rack including a dunnage bar locking mechanism for removably securing a dunnage bar between the end walls of the shipping rack. The mechanism comprises a housing secured to one end wall. A piston element is mounted within the housing for reciprocal movement. The piston element is removably secured to one end of a dunnage bar. A handle is pivotally mounted to the housing. The handle has an open position to move the piston element toward the end of the dunnage bar and a closed position to move the piston element away from the end of the dunnage bar. A means interconnects the handle and the piston element for allowing relative movement between the piston element and handle when the handle is in the closed position as a consequence of the dunnage bar being impacted by an external force.
