    • A garage door operator (20) for moving a garage door (26) between open and closed positions includes a head unit (28) for being held by a support structure positioned remote from the door (26) with the head unit (28) having a motor (48) and a drive wheel (60) with spaced teeth on its periphery for being driven by the motor (48). The operator (20) also includes an elongate rail (40) having a first end which is held by a support structure disposed adjacent and above the door (26) with the rail (40) including a pulley (46) located adjacent the first end. The rail (40) also includes a second end for being held adjacent to and in alignment with the drive wheel (60). The operator (20) also includes a drive belt assembly (34) for training about the drive wheel (60) and the pulley (46) and for being supported by the rail (40). The belt assembly (24) includes a length of a plastic belt (76) with teeth (78) on one surface thereof matching the teeth (42) on the drive wheel (60). The belt assembly (34) further includes a trolley (36) for connection to the garage door (26) and a first connector (82) for joining one of the plastic belt (76) to one end of the trolley (36). The connector (82) includes a belt clip (96) including a pair of spaced, aligned side walls (100,102) with one side wall (100) having an inside surface with undulations (106) corresponding to the teeth (78) of the plastic belt (76). The connector (82) further includes a clip holder (98) deformable from an as-formed position in which the holder can receive the side walls flanking the belt (76) with the belt teeth (78) aligned with the undulations (106), to a deformed position in which the holder firmly holds the side walls with the belt positioned therebetween.
    • 用于在开闭位置之间移动车库门(26)的车库门操作器(20)包括头单元(28),用于由位于远离门(26)的支撑结构保持,头单元(28)具有 电动机(48)和驱动轮(60),其周边上具有间隔开的齿,以由马达(48)驱动。 操作者(20)还包括细长轨道(40),其具有第一端,该第一端由邻近并在门(26)附近设置的支撑结构保持,轨道(40)包括位于第一端附近的滑轮(46) 。 导轨(40)还包括用于保持与驱动轮(60)相邻并与驱动轮(60)对准的第二端。 操作者(20)还包括驱动带组件(34),用于围绕驱动轮(60)和滑轮(46)进行训练并由轨道(40)支撑。 皮带组件(24)包括在一个表面上与驱动轮(60)上的齿(42)匹配的具有齿(78)的塑料带(76)的长度。 带组件(34)还包括用于连接到车库门(26)的手推车(36)和用于将塑料带(76)中的一个连接到手推车(36)的一端的第一连接器(82)。 连接器(82)包括带夹(96),带夹(96)包括一对间隔的排列的侧壁(100,102),其一侧壁(100)具有内表面,其具有对应于塑料的齿(78)的起伏 皮带(76)。 连接器(82)还包括可从形成位置变形的夹持器(98),其中保持器可以接收带(78)侧面的侧壁,带齿(78)与波纹(106)对准, 到其中保持器牢固地保持侧壁并且带位于它们之间的变形位置。
