Positioning apparatus of a collapsible umbrella
The invention relates to a positioning apparatus of a collapsible umbrella, which includes a runner composed of a connector and a receiver being placed around a shaft having several tubes. A positioning apparatus is provided in a top tube of the shaft, which includes a rod connecting with a bow. The bow will be inclined outward to engage with the connector for positioning the runner and the umbrella in stable as the umbrella is opened. The bow has its bottom end an arched convex being placed in the receiver that facilitates user to close the umbrella more conveniently.
A collapsible umbrella has a small volume for easy carrying when it is closed. Such umbrella includes a shaft composed of several tubes and a frame containing several ribs.
