A flashing umbrella allowed to emit flashing light on rainy, dark day has a tubular handle connected to a hollow rod which is further connected to an upper tube. An upper collar is engaged at the upper periphery of the rod having a plurality of ribs pivotally extending therefrom. A plurality of LEDs each is installed at the end of a corresponding rib. The tubular handle has a circuit board and a battery installed therein for providing electrical pulses from the circuit board. A button switch is installed on the tubular handle for controlling the ON/OFF of the circuit board. A positive electrical line and a negative electrical line extend from the circuit board and elongate upward inside the rod and each having a plurality of branches each extending therefrom to electrically connect a corresponding LED, thereby transmitting the electrical pulses from the circuit board to the LEDs and enable the latter to flash.

Flashing umbrella

There is disclosed a one-hand openable and closable umbrella which does not cause relative rotational movement and displacement between an inner shaft and an outer shaft. The inner shaft has a U-shaped groove extending in the lengthwise direction thereof and the outer shaft has a convex block provided inside a lower nest mounted on the top of the outer shaft. By the engagement of the convex block of the outer shaft with the U-shaped groove of the inner shaft, the inner and outer shaft neither turn nor displace relative to each other when the latter slides on the latter. Moreover, since a plastic sleeve is put on the upper end portion of the inner shaft inside a spring mounted thereon, any frictional force between the spring and the inner shaft and between the spring and an upper nest can be decreased, by which the umbrella can be smoothly opened and closed.
