Patent

CA 2123158

A moving slide has a pair of flexible curtains mounted to its front and rear surfaces, the curtains being attached at opposite ends to front and rear support posts mounted to a base. The support posts have upper and lower pulleys. A cable is connected to the front of the slide and runs in this fashion: first horizontally across the top pulley, thence to the lower pulley, thence to the other support post, thence upwardly and finally around to the horizontal portion which connects to the rear of the slide. The cable is tensioned to a predetermined load which remains constant throughout the slide travel as the front and rear horizontal portions of the cable move. The flexible curtains are suspended from, but are not rigidly attached to, the cable. Thus, as the curtains expand and contract, the moving horizontal portions of the tensioned cable ride smoothly through the curtains, maintaining curtain support.

Curseur mobile comportant une paire de rideaux flexibles montés sur ses faces avant et arrière, les rideaux étant reliés aux extrémités opposées de montants de support avant et arrière fixés à une base. Les montants de support comportent des poulies supérieures et des poulies inférieures. Un câble est rattaché à l'avant du curseur et disposé de la façon suivante : de l'horizontale, il s'enroule sur la poulie supérieure avant de descendre vers la poulie inférieure d'un premier montant; horizontalement, il rallie la poulie inférieure de l'autre montant de support et remonte vers la poulie supérieure avant de retourner à l'horizontale, où il est rattaché à l'arrière du curseur mobile. Le câble est tensionné à une valeur prédéterminée qui demeure constante durant les déplacements du curseur. Les rideaux flexibles sont suspendus au câble, mais n'y sont pas fixement rattachés. Ainsi, malgré les mouvements de dilatation et de contraction des rideaux, les portions mobiles horizontales du câble continuent de passer sans accroc à travers les rideaux, tout en assurant le support attendu.
