    • The present invention provides a structure of shaft of automatic umbrella, which includes a shaft assembly including a second section having a top end fixed to an internal plug. An inner tube is fixed at a top end thereof to the internal plug and receives therein an operation tube having a bottom coupled to an operation plug. The inner tube receives in a top portion thereof a pulley around which an operation cable wraps. An end of the operation cable is fixed to the bullet-like member and an opposite end fixed to the operation plug. To open the umbrella, a push button is depressed and an expansion spring pushes upward the second section so that the runner cable and the operation cable drive the runner and a third shaft section upward to completely open the umbrella.
    • 本发明提供了一种自动伞的轴的结构,其包括一个轴组件,该轴组件包括具有固定到内部插头的顶端的第二部分。 内管在其顶端固定到内部插头,并在其中容纳具有联接到操作插头的底部的操作管。 内管在其顶部容纳有操作电缆卷绕的滑轮。 操作线的一端固定在子弹状部件上,固定在操作插头上的相对端。 为了打开伞,按钮被按压,并且膨胀弹簧将第二部分向上推动,使得流道缆索和操作缆线向上驱动转轮和第三轴部分以完全打开伞。

    • A triple-folding umbrella skeleton includes a plurality sets of frame arranged around the middle tube and pivotably mounted on the notch and runner respectively. Each frame set includes a first rib, a second rib, a third rib, a stretcher and a first link. One end of the first rib is pivotably mounted on the runner. The two ends of the second rib is pivotably mounted to the other end of the first rib and one end of the third rib respectively. One end of the stretcher is pivotably mounted on the notch, and other end of the stretcher is pivotably mounted to the first rib. The first link is generally parallel to the first rib, and its two ends is pivotably mounted to a first extension portion of the second rib and the stretcher respectively. The first link, the stretcher, the first rib and the first extension portion cooperate to form a quadric link structure. The triple-forming umbrella skeleton is characterized in that each frame set further includes a connecting spring and a second link generally parallel to the second rib. One end of the second link is pivotably mounted to a second extension portion of the third rib, and the other end of the second link is connected to the first rib via the connecting spring. Whereby, each frame set can be expanded to a largest extent to obtain a largest canopy shielding area, and only a smaller force is needed to open the triple-folding umbrella skeleton, due to the retractability of the connecting spring.
