Abstract: A garage door operator is disclosed which has a motor-driven screw nearly enclosed within a guide, and a partial nut is guided by this guide means and moved longitudinally therealong by engagement with the rotating screw. The partial nut is adapted to be connected to a garage door to open and close the same. In order to shorten the package in which the garage door opener is shipped, the screw and guide means are in two or more parts and adapted to be coupled together to make an operative long screw and an operative long guide means. The screw parts, instead of being connected together at the factory by a double pivot connection, are shipped to the customer in a disconnected condition but one in which the coupling readily may be connected in a proper phase to avoid mismatch of the threads. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract translation: 公开了一种车库门操作器，其具有几乎封闭在引导件内的电机驱动螺钉，并且部分螺母由该引导装置引导并通过与旋转螺钉的接合而纵向移动。 局部螺母适于连接到车库门以打开和关闭车门。 为了缩短运送车库门开启器的包装件，螺钉和导向装置处于两个或多个部件中并且适于联接在一起以制造可操作的长螺钉和可操作的长引导装置。 螺丝零件，而不是通过双重枢轴连接在工厂连接在一起，以不连续的状态运送到客户，但是其中耦合容易地可以以适当的相位连接，以避免螺纹不匹配。 上述摘要仅仅是一般应用的简历，不是所有操作原理或应用的完整讨论，并不被解释为对所要求保护的主题的范围的限制。
