Abstract:
A collapsible umbrella structure, which comprises:a main shaft having an elongated slot having an upper end and a lower end;a running hub slidably movable along the main shaft, the running hub being held at a bottom position when the umbrella is set in a collapsed state and at an upper position when the umbrella is set in an opened state; andan upper pressable stopper, pressably mounted in the lower end of the elongated slot in the main shaft, for holding said running hub at the upper position when the umbrella is opened;said upper pressable stopper being formed with a stop portion and a substantially L-shaped bendable leg having a first lower end linked to the stop portion and a second upper end fixed to the main shaft on the upper end of the elongated slot;whereinsaid stop portion of the upper pressable stopper is capable of being moved into said main shaft by the running hub when the running hub is moving from the bottom position to the upper position, and subsequently capable of being restoring to the unpressed position after the running hub has passed thereby so as to stop the running hub from moving downwards, thereby holding said running hub at said upper position.
