ABSTRACT:
BACKGROUND OF THE INVENTION
A conventional large umbrella, such as a beach umbrella or an outdoor used umbrella, includes two layers of umbrella cover. When the heavy wind blows, it can be released from the space between the two covers. So this prevents the umbrella from being blown down or broken because of the ribs being inverted upward. The known umbrella includes two frames to connect with related covers and connecting ribs to control the opening and closing of the umbrella. The assembly of the prior structure is somehow complex and is heavy in total weight. It is inconvenient to use and in storage.
Accordingly, the primary object of the present invention is to provide an improved umbrella for releasing wind, which includes a single frame with a supporting rib to connect with the upper cover. It provides a simple assembly to obtain the predicted effect and improvement. Now the features and advantages of the present invention will be described in detail with reference to the accompanying drawings.
