An adapter arrangement is provided for connecting the inlet opening of a cold air distribution chute with the cold air discharge opening of a refrigeration unit that is mounted in a opening contained in the front wall of the body of a refrigeration vehicle, characterized in that the forward portion of the chute is collapsed upwardly upon the application of a vertical force thereto, thereby to prevent tearing or damage of the chute. The bottom edge of the chute inlet opening is connected with a weighted horizontal rod or bar that is guided for vertical sliding movement on vertical guide rods that are mounted by brackets on opposite sides of the cold air discharge opening of the refrigeration unit. Each end of the horizontal rod is connected with the associated guide rod by a connecting member that is telescopically slidably connected with the rod.

[ What is claimed is:] [1.] Adapter means for connecting the inlet opening of a flexible cold air distribution chute arranged within the body of a refrigeration vehicle with the cold air discharge opening of a refrigeration unit that is externally mounted on the vertical front wall of the refrigeration vehicle body and extends through an opening contained in the front wall, the refrigeration unit including an outlet opening that communicates with the interior of the refrigeration body, comprising:(a) a pair of vertical guide members;(b) means for connecting said vertical guide members with the interior surface of the refrigeration body front wall on opposite sides of the refrigeration unit discharge opening;(c) an elongated horizontally-arranged weight member extending between said vertical guide members;(d) a pair of connecting means connecting the ends of said weight member for vertical movement relative to said guide means, each of said connecting means including a connecting member that is connected for longitudinal sliding movement relative to said horizontal weight member; and(e) means for connecting the chute inlet opening concentrically about said refrigeration unit discharge opening, said chute inlet opening connecting means including means for connecting the lower portion of said the chute inlet opening with said horizontal weight member, whereby upon the application of an upwardly-directed force upon the lower surface of the chute adjacent the chute inlet opening, the horizontal weight bar and the adjacent portions of the chute are displaced upwardly relative to said vertical guide means.
