Abstract: A closure operator such as a garage door operator utilizes an apertured flexible tape. The tape is enclosed in a guide and a drive sprocket has teeth engaging the apertures to apply both tension and compression forces to open and close a door. The apertures are enlarged in width and length and the tape has fewer apertures per-unit-length compared to the prior art tape. This decreases the stress per-unit-area in the tape at each tooth and increases the shear strength of the webs between successive apertures to be more nearly equal to the tensile strength of the tension band areas of the tape.

Abstract: A garage door operator is provided which includes a flexible, elongated tape within a relatively rigid, elongated guide rail mounted in a garage. The tape has first and second runs longitudinally disposed in first and second guide channels in the guide rail. A motor is connected to drive a drive wheel with the tape wrapped around a part of the drive wheel and having a positive drive engagement therewith. A carriage is longitudinally guided on the guide rail and is connected both to the tape for movement therewith and by a link to a garage door for opening and closing movements of the door. The guide rail may be cut into sections for a shorter shipping package, and the tape coiled in a loop during shipment but then disposed within the guide channels during operation, the guide rail being spliced into one long, continuous assembly for use in the garage. 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: 提供车库门操作器，其包括在安装在车库内的相对刚性的细长导轨内的柔性细长带。 该带具有纵向设置在导轨中的第一和第二引导通道中的第一和第二延伸。 电动机被连接以驱动驱动轮，其中磁带缠绕在驱动轮的一部分上并与其成正面的驱动接合。 滑架在导轨上被纵向引导，并且两者连接到磁带上以便与其一起运动，并且连接到车库门以便打开和关闭门的运动。 导轨可以被切割成较短的运输包装的部分，并且在运输期间磁带卷绕在回路中，然后在操作期间布置在引导通道内，导轨被拼接成用于车库的一个长的，连续的组件。 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。
