Claim 0:
1. A conveyor mat assembly, comprising:
a frame including a first end and a second end;
a first handle coupled to the frame;
a conveyor mat configured to transition between a retracted state in which the conveyor mat resides between the first end and the second end of the frame, and a deployed state in which the conveyor mat at least partially extends beyond the second end of the frame, the conveyor mat including:
axles disposed along a length of the conveyor mat,
linkages coupled to the axles along the length of the conveyor mat and across a width of the conveyor mat,
supports coupled to the axles along the length of the conveyor mat and across the width of the conveyor mat, and
rollers coupled to the axles along the length of the conveyor mat and across the width of the conveyor mat, the rollers providing a rolling surface for items being transported via the conveyor mat in the deployed state;

torsional springs disposed about the axles and operably coupled to at least a portion of the supports, the torsional springs imparting a force to transition the conveyor mat to the deployed state; and
a tensioning mechanism coupled to the frame proximate to the first end, the tensioning mechanism including:
a second handle,
a spool rotatably engaged with the second handle,
a cord at least partially wound about the spool and coupled to the conveyor mat, and
a locking mechanism configured to engage with the cord to control transitioning of the conveyor mat between the retracted state and the deployed state.
