Abstract: A quiet drapery pull system includes an elongated track that receives a master car and auxiliary cars. The track defines a pair of curved surfaces for nested receipt of roller members of the cars to facilitate linear tracking of the cars. The cars preferably include tires that are made from a resilient material to limit noises caused by rolling contact and by slipping and dragging of the tires upon contact with surface imperfections of the track. The drapery pull system preferably includes a drive belt connected to a reversible motor and to the master car for driving the master car in each of opposite directions. The drive belt is preferably made from a resilient material to limit noise associated with contact between the drive belt and drive pulley and between the belt and the track.

Abstract translation: 一个安静的帷幔牵引系统包括一个细长的轨道，接收主车和辅助车。 轨道定义了一对弯曲表面，用于嵌套接收车辆的滚子部件，以便于车辆的线性跟踪。 汽车优选地包括由弹性材料制成的轮胎，以限制由滚动接触引起的噪音以及在与轨道的表面缺陷接触时轮胎的滑动和拖动。 帷帘牵引系统优选地包括连接到可逆电动机和主车的驱动带，用于在相反的方向上驱动主车。 驱动带优选地由弹性材料制成，以限制与驱动带和驱动带轮之间以及带和轨道之间的接触相关联的噪声。
