ABSTRACT:
Disclosed is an umbrella with a stretch structure for selectively collecting rainwater mainly including a stick with a handle, an upper hub member and a lower hub member vertically movably put around the stick to respectively pivotally connect umbrella main and secondary ribs around them, and an umbrella cover fixed to and centered at a top end of the stick with its outer edge connected to outer ends of the main ribs and a middle portion to outer ends of the secondary ribs. The upper hub member has a downward extended retaining block to detachably engage with a control block pivotally connected to a push-button switch fixed to one side of a lower tube portion of the lower hub member. A push pin is provided to a lower end of the tube portion to selectively extend into different holes formed on the stick. Whereby, when the upper and the lower hub members are locked together by the engaged retaining block and control block and are pulled down together until the push pin passes and extends into a lower through hole on the stick, the umbrella is closed with the umbrella cover in a folded state for collecting rainwater attached to the umbrella cover.
