Abstract
A roll up door which may be used in the back of a van body has a plurality of panels arranged edge-to-edge with a thin flexible sheet glued to the outside face of the panels and a flexible belt attached to each pair of adjacent panels at the rear face of these panels. A roller extends from each end of each panel and is received by a generally inverted L-shaped guide track. With this arrangement, the panels may cant while moving from the vertical to the horizontal leg of the guide channels by virtue of the belts which hinge and collapse allowing the outer sheet to bend as well.
