    • An overhead door assembly for opening and closing a door opening comprises a plurality of door sections (10) having hinges (12) for hingedly joining the door sections (10) together. A pivot (26) on an upper end region of each door section (10) pivotally connects a tandem arm (28). Each tandem arm (28) has at opposite ends thereof a rotatably mounted roller (20). A lowermost door section has a roller (21) rotatably mounted at the lowermost region of the door section. Two lead arms (29) each have a first end pivotally connected to the pivot (26) of the uppermost door section and an opposite end having a rotatably mounted roller (25). An axle (14) is rotatably mounted above the door opening (22) and having springs (16) for urging the axle (14) to rotate in opposite senses. Drums (15) are fixedly mounted on the axle (14) and aligned with each side of the door opening (22). Two cables (19), each extend from the lowermost door section about the drum (15) and extending to the opposite end of the lead arm (29). Two guides (24) extend upwardly along each side of the door opening (22) for guiding the door sections (10) as the door travels to open and close the door opening (22). A motor (32) drives the axle (14) in one sense tensioning the cable (19) extending from the lowermost door section for opening the door and for driving the axle (14) in an opposite sense tensioning the cable (19) extending at the opposite end of the lead arm (29) for closing the door.
    • 用于打开和关闭门开口的顶部门组件包括具有用于将门部分(10)铰接在一起的铰链(12)的多个门部(10)。 每个门部分(10)的上端区域上的枢轴(26)可枢转地连接串联臂(28)。 每个串联臂(28)的相对端具有可旋转地安装的辊(20)。 最下门部分具有可旋转地安装在门部分的最下部区域的辊子(21)。 两个引导臂(29)各自具有枢转地连接到最上门部分的枢轴(26)的第一端和具有可旋转地安装的滚子(25)的相对端。 轴(14)可旋转地安装在门开口(22)的上方,并具有用于推动轴(14)以相反方向旋转的弹簧(16)。 鼓(15)固定地安装在轴(14)上并与门开口(22)的每一侧对齐。 两个电缆(19)各自从最下面的门部分围绕鼓(15)延伸并延伸到引导臂(29)的相对端。 两个引导件(24)沿着门开口(22)的每一侧向上延伸,以在门行进时引导门部分(10)以打开和关闭门开口(22)。 电动机(32)以一种感觉来驱动轴(14),该感应张紧从最下门部分延伸的电缆(19),用于打开门,并且以相反的方向驱动轴(14),该方向张紧电缆(19) 引导臂(29)的相对端用于关闭门。
