Patent

CA 2185080

A roll up door which may be used in the back of a van body comprises 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.

Cette invention concerne une porte à enroulement vertical destinée à fermer l'arrière d'une caisse de camion, ladite porte étant composée d'une pluralité de lattes jointives sur la face extérieure desquelles est collée une feuille souple mince. De l'autre côté, chaque paire de lattes adjacentes est reliée par un ruban souple. Chacune des lattes porte un galet à ses deux extrémités qui circule dans un chemin de roulement ayant la forme générale d'un L inversé. Grâce à cette disposition, les lattes peuvent s'incliner lorsque les galets correspondants passent de la partie verticale à la partie horizontale du chemin de roulement, les courroies se plissant à la manière d'un soufflet et permettant à la feuille de revêtement extérieur de plier également.
