Abstract

A portable warning device in the form of a stanchion which is to be readily movable and locatable at any desired location. The portable warning device includes a movable light assembly to attract attention to the warning device to any human being which passes nearby. Once the human being reaches within a certain number of feet in distance from the warning device, a prerecorded message is emitted to audibly warn the human being. Any unauthorized removal of the warning device will immediately activate an antitheft alarm which will produce some form of an audible signal calling attention to the fact that thievery of the device is occurring.

Claims

1. A portable warning device comprising:

a stanchion having an upper end and a lower end, said lower end adapted to be located on a supportive surface, said upper end being spaced from the supportive surface, said stanchion having a plurality of side walls each, said side wall being planar with the arrangement of said side walls being polygonal;

light means located at said upper end, said light means being readily visually observable by a human being when coming into close proximity with said stanchion;

antitheft alarm means connected to said stanchion, said antitheft alarm means to activate an annunciator upon said stanchion being moved from its established location;

human voice recording means connected to said stanchion, said recording means being activatable to record a particular message;

sensor means connected to said stanchion, said sensor means being activated upon a human being moving within a certain distance of said stanchion, said sensor means being wireless and detecting heat of the human being, said sensor means comprising a pair of sensor, switch means associated with said stanchion, said switch means for selecting either one said sensor or both said sensors, one said sensor being mounted within one said side wall, the remaining said sensor being mounted within another said side wall, said sensors functioning to be sensitive to the entire three hundred sixty degree arear directly about said stachion; and

sound reproduction means connected to said stanchion, said message being reproduced and transmitted upon activation of said sensor means.

2. The portable warning device as defined in claim 1, wherein:

said light means being movable during activation.

3. The portable warning device as defined in claim 2 wherein:

said light means comprising a strobe.

4. The portable warning device as defined in claim 1 wherein:

said annunciator comprising a sound emitting device.

5. The portable warning device as defined in claim 1 wherein:

said polygonal arrangement comprising a square, said sensors being mounted within opposing said side walls.
