Deployable aerodynamic device for rear of a cargo body

An device for a rear of a cargo body comprising:

• a side panel mounted between a frame of the cargo body and to a support that hinges between a retracted position and a deployed position, the support comprising a rotating member that is hingedly attached at or near a rear of the frame of the cargo body and at or near a trailing edge of the side panel;
• a side take-up area into which the side panel is gathered in the retracted position;
• a moving top frame member operatively connected to the support that coordinates movement of a top panel between the retracted position and the deployed position;
• and
• a top take-up area into which the top panel is gathered in the retracted position.

• a side take-up area into which the side panel is gathered in the retracted position;
• a moving top frame member operatively connected to the support that coordinates movement of a top panel between the retracted position and the deployed position;
• and
• a top take-up area into which the top panel is gathered in the retracted position, wherein the side take-up area and the top take-up area are configured to retain the side panel and top panel away from a door of the cargo body to allow operation of the door and the side panel and top panel are configured to be in an aerodynamic tapered position in the deployed position.

An aerodynamic device for a rear of a cargo body comprising:

• a side panel that moves between a retracted position and a deployed position along a guide that is mounted on a side of the cargo body;
• a rotating member interconnected between the cargo body and the side panel that maintains a shape and inward/rearward taper of the panel as it swings from the retracted position to the deployed position;
• a top take-up area into which the top panel is gathered in the retracted position
• a linkage that joins the rotating member to a top panel so that the top panel moves between the retracted position and the deployed position in coordination with the rigid side panel;
• and
• a biasing mechanism that moves the rigid side panel and the top panel to at least one of the retracted position and the deployed position.

• a top panel that moves between a retracted position and a deployed position;
• a rotating member interconnected between the cargo body and the side panel that maintains a shape and inward/rearward taper of the panel in the deployed position;
• a biasing mechanism that moves the side panel and the top panel to at least one of the retracted position and the deployed position;
• and
• an actuator that, when actuated, moves the side panel and the top panel to the other of the retracted position and deployed position by overcoming the biasing force of the biasing mechanism.
