Abstract

A signal stick including a handle holding a battery set, a connector connected to the handle by a screw joint to hold a circuit board, a transparent sleeve coupled to the connector, an inner tube mounted within the transparent sleeve and having a bottom end plugged into an annular top open chamber of the connector and a top end made with locating grooves, a negative metal wire rod and three positive metal wire rods respectively hung on the locating grooves of the inner tube within the transparent sleeve and connected to the circuit board, a plurality of LEDs of different colors respectively connected between the negative metal wire rod and the positive metal wire rods, a selector switch mounted on the connector and adapted for turning on a particular color of LEDs, and a manual/auto control switch shifted between an automatic mode to automatically turn on the LEDs in a predetermined order, and a manual mode to let the LEDs be controlled by the selector switch.

Claims

1. A signal stick comprising:

a hollow cylindrical metal handle;

a battery set mounted within said handle;

a hollow cylindrical connector having a bottom end fastened to said handle by a screw joint;

a circuit board mounted within said connector and turned with said connector into electrical contact with said battery set;

a transparent sleeve having a bottom end connected to said connector and a top end covered with a cap;

a plurality of metal wire rods mounted within said transparent sleeve and respectively connected to positive and negative terminals of said circuit board;

a plurality of LEDs having respective positive contact pins and negative contact pins respectively welded to said metal wire rods;

switch means mounted on said connector and connected between said circuit board and said metal wire rods and controlled to turn on said LEDs;

wherein said connector comprises an annular top open chamber and an inner race surrounded by said annular top open chamber;

the cap of said transparent sleeve has an inside annular coupling groove;

an inner tube is mounted within said transparent sleeve to hold said metal wire rods in place, having a bottom end plugged into the annular top open chamber of said connector, a top end plugged into the inside annular coupling groove of the cap of said transparent sleeve, and four equiangularly spaced locating grooves at the top end;

said metal wire rods have a respective hooked top end respectively hooked on the locating grooves of said inner tube and include a first positive metal wire rod, a second positive metal wire rod, a third positive metal wire rod, and a negative metal wire rod, said negative metal wire rod having a bottom end connected to the negative terminal of said circuit board, said first, second and third positive metal wire rods having a respective bottom end alternatively connected to the positive terminal of said circuit board by said switch means;

said LEDs include a plurality of red LEDs having a respective positive metal contact pin connected to said first positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod, a plurality of yellow LEDs having a respective positive metal contact pin connected to said second positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod, and a plurality of green LEDs having a respective positive metal contact pin connected to said third positive metal wire rod and a respective negative metal contact pin connected to said negative metal wire rod;

said switch means comprises a red/yellow/green selector switch controlled to connect to positive terminal of said circuit board to one positive metal wire rod, and a manual/auto control switch shifted between an automatic mode to automatically connect said positive metal wire rods to the positive terminal of said circuit board in a set order, and a manual mode to let said positive metal wire rods be alternatively and manually connected to the positive terminal of said circuit board by said red/yellow/green selector switch.

2. The signal stick of claim 1 further comprising a metal cylinder adapted for mounting in said handle to hold a relatively smaller size of battery set.

3. The signal stick of claim 1 wherein said inner race of said connector defines a coupling hole adapted for holding a transparent sleeve of relatively smaller diameter.
