Abstract

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.

Claims

1. A flashing umbrella comprising a tubular handle, a hollow rod connected thereto, an upper tube connected to said rod at a top end thereof, said rod being in communication with said upper tube and said handle, an upper collar being formed substantially at a top periphery of said rod, a plurality of ribs being pivotally connected to said upper collar and extending in radial directions therefrom, each said rib being integrally formed with three faces thus defining a channel therein, a plurality of tips each engaged to one end of a corresponding said rib, a plurality of LEDs each being attached on a corresponding said tip, said handle having a recess on one face thereof for receiving a battery and a circuit board therein, a first cover being fit on an upper portion of said recess suitable to cover said circuit board, a second cover being fit on a lower portion of said recess suitable to cover said battery, said circuit board electrically connected to said battery and having a positive electrical line and a negative electrical line extending therefrom for providing electrical pulses thereacross, a button switch being installed on said first cover for turning ON/OFF said circuit board, a plurality of branches of said positive electrical line each being electrically connected to a corresponding LED, a plurality of branches of said negative electrical line each being electrically connected to a corresponding LED, each said rib receiving a pair of branches comprising one of said positive branches and one of said negative branches in the channel thereof, each said pair of branches providing pulses to a corresponding said LED when said circuit board is turned ON, a glue being fed in the channel of each said rib and applied on connection points between said LED and said pair of branches, thus further fixing said pair of branches inside said ribs and preventing short circuit between said connection points.

2. The flashing umbrella as claimed in claim 1 further comprises a ferrule cap engaged at a top of said upper tube for securely sealing said upper tube preventing water entering thereinto.
