    Abstract: Folding door construction including a sinuous overhead track and means for moving a folding door therealong. The moving means includes a power driven pulley mounted cable laid out to define two elongated runs guided over a series of spools which maintain a generally centralized orientation of the cable throughout the oppositely directed track curvings. The lead post of the door is secured to one of the cable runs for movement thereby through a thin vertical cable clamp projecting upwardly from the lead post support assembly.

    Abstract translation: 折叠门结构,包括一个弯曲的架空轨道和用于在其上移动折叠门的装置。 移动装置包括一个动力驱动的滑轮安装的电缆,其布置成限定两个细长的行程,引导在一系列线轴上,这些线轴保持电缆在整个相对方向的轨迹曲线上的大致集中的方位。 门的引导柱固定到一个电缆行程中,从而通过从引导柱支撑组件向上突出的薄的垂直电缆夹来移动。
