An articulated door and door guiding track covers storage bays of a beverage body. An articulated door is formed by engaging a plurality of polymeric panel sections into a sequence such that each panel section can be positioned at varying angles with respect to an adjacent engaged panel section. The articulated door is guided between an open position and a closed position bya door guiding track comprised of a left channel facing a right channel across adoor opening. The sequence of panel sections is slidably positioned in the door guiding track by having a left end of each panel section extending into the leftchannel and a right end of each panel section extending into the right channel. A counterbalance comprised of a spring-loaded drum having a strap with one end attached to the bottom of the door and another end attached to the center of thedrum is provided to assist in raising and lowering the door. As the door is opened, the strap rolls up around itself and continually applies a symmetric force to the door.

Cette invention concerne une porte roulante à panneaux articulés et ses rails de guidage, pour la fermeture de compartiments de stockage. La porte est composée de panneaux en polymère articulés les uns aux autres de manière que chacun puisse adopter une position en angle variable par rapport au panneau qui précède et à celui qui suit. Le mouvement de la porte est guidé par des rails disposés face à face, l'un sur le montant gauche et l'autre sur le montant droit de la baie. L'extrémité gauche des panneaux est insérée dans le rail gauche, et l'extrémité droite dans le rail droit, de sorte que les panneaux glissent l'un à la suite de l'autre dans les rails. Un contrepoids constitué par un tambour et une courroie dont une extrémité est attachée au centre du tambour et l'autre au bas de la porte, facilite la manoeuvre de la porte. Lorsque la porte s'ouvre, la courroie s'enroule sur le tambour et exerce de façon continue une force d'équilibre.
