ABSTRACT:
A collapsible umbrella structure with hand protection is provided, which is constructed in such a manner that can help prevent the user's hand from being injured when the user is using his/her hand to manually open or collapse the umbrella. The collapsible umbrella structure includes a main shaft; a running hub slidably movable along the main shaft, the running hub being held at a bottom position when the umbrella is collapsed and at an upper position when the umbrella is opened; and an upper pressable stopper, pressably mounted on the main shaft, for holding the running hub at an upper position when the umbrella is opened. The upper pressable stopper is pressed down by the running hub when the running hub is being manually moved from the bottom position to the upper position, and subsequently capable of restoring to the unpressed position after the running hub has passed therethrough so as to stop the running hub from moving downwards, thereby holding the running hub at the upper position. This collapsible umbrella structure allows the user's hand not to come in touch with some sharp edges that are formed by machine cutting on the umbrella, thus able to help prevent the user's hand from being injured when the user is using his/her hand to manually open or collapse the umbrella.
