<p>The invention is directed to a curtain track assembly which finds use in vehicles, especially refrigerated vans and trucks, to assist maintain the internal temperature of the cargo area of a vehicle as perishable food items are unloaded. The assembly comprises a first track (5) fixed to one side wall (2) of the vehicle and a second track (6) fixed to an opposite wall (3) and running substantially parallel to the first track (5). A third track (7) has one end which can slide along the first track (5) and its other end which can slide along the second track (6). Each end of the third track (7) is a biased frictional fit against the inner surface of the respective tracks (5, 6) allowing an infinitely adjustable positioning of the third track (7) along the tracks (5, 6). One or more curtains can be drawn along the third track (7) to provide a thermal barrier within the vehicle. As the food items are unloaded, the third track (7) is slid back along the tracks (5, 6) keeping the curtains close to the remaining food items in the vehicle thus shielding them from the environment outside of the cargo area.</p> |
