ABSTRACT:
A windproof umbrella structure includes mainly a connector being provided at a pivoted position of the main rib and the stretcher to engage with a second rib. The invented assembled frame is covered by an upper cover and a lower cover and obtains a better umbrella strength. When the upward wind occurs, the airflow can pass through the gap between the two covers for avoiding the damage of the ribs.
