Abstract

A portable traffic light assembly includes a substantially rectangular base component having planar upper and lower surfaces and four side walls therebetween. A plurality of wheels are disposed on the lower surface for rolling the device from one location to another. Extending from the top surface of the base component is a telescoping support leg operable with a hydraulic pump to selectively move the leg between an extended and a retracted position. Secured to the upper distal end of the support leg is a traffic light unit having four side walls with a green, yellow and red light on each side wall thereof. The hydraulic lift pump and signal lights may be selectively operated with a remote control means allowing a user to temporarily direct traffic from a location safely distanced from oncoming traffic.

Claims

1. A portable traffic light assembly comprising:

a hollow base component having upper and lower surfaces and a plurality of sidewalls, each sidewall having an aperture thereon with a photoelectric sensor adjacent thereto;

a plurality of roller means on the lower surface of said base component for transporting the device from one location to another;

a telescoping support leg extending from the upper surface of said base component, said leg movable between an extended and a retracted position;

a traffic signal unit secured to a distal end of said support leg, said unit including a box shaped housing having four side walls, each side wall having a plurality of discrete signal lights thereon for simultaneously signaling traffic flowing in various directions;

a lift means for automatically extending and retracting said support leg to position said traffic signal unit at a desired height, said lift means including a hydraulic pump received within said base component in mechanical communication with said telescoping support leg;

a remote control means for selectively activating each of said signal lights and said lift means from a remote location;

an automatic control means for automatically illuminating each of said lights for a predetermined duration;

a transmitter means for transmitting a signal to said sensors;

a receiver means received within said base component and in selective communication with said sensors, each of said signal lights and said lift means;

a first battery means for providing electricity to said lift means;

a second battery means for providing electricity to said signal lights;

a switch means for activating said remote control means.
