The Safety Sign is a batterypowered,
lighted, handheld Stop/Slow reversible sign to be used
by crossing guards, highway-crew flagmen, traffic control officers,
and others who control traffic. Design intent is that the Safety
Sign would be more visible, and hence more effective, than
traditional signs or flags used in traffic-control situations.
• The Safety Sign would be fabricated of lightweight sheet metal and hard,
injection-molded ABS thermoplastic. The sign itself would feature a bright red
reflective paint to catch motorists attention.
• The shape of the sign would be octagonal — eight-sided, like a stop sign —
and would be reversible, bearing the word STOP on one side and SLOW on the
other. The Safety Sign would be equipped with a sturdy, post-like gripping handle
descending from its base. The handle would be hollow, and incorporate an interior,
removable, rechargeable battery-pack, and an On/Off switch on the exterior. The
battery-pack would power arrays of LED (light-emitting diode) lights: on the
STOP side of the sign, the periphery of the octagon would be equipped with a
continuous series of bright white, strobe or flashing LED’s, while the word “STOP”
itself would also be lit to similar effect. Thus, even at night and at a distance, the
approaching motorist would see the familiar outline of a stop sign, and, as he or she
grew closer, the word STOP! Another consideration would be A/C D/C power, or
in some instances solar powered.
• On the reverse of the sign, the word “SLOW”, and the periphery of the
sign, would be equipped with LED’s, but these would strobe or flash in yellow.
Thus, an approaching motorist would be prepared to stop by the shape of the sign,
then, having slowed in preparation, would be flagged through, on SLOW. Directional
arrows could be placed under the word “SLOW” and could be individually lit
to indicate in which direction traffic should flow.
• The Safety Sign would use bright, antiglare bulbs that would also meet fog
light requirements. These lights will flash intermittently between the yellow border
lights to the white lights that illuminate the words, STOP and SLOW. Any lights
used would be made to meet state regulations. As an additional consideration, in the
future, the Safety Sign could be made digital while still abiding by state and federal
• The Safety Sign would be made available in various sizes from a hand held
size up to the standard street sign size for increased visibility.
ADVANTAGES & BENEFITS
• The Safety Sign, a handheld, lighted, Stop/Slow sign to be used by those
who direct vehicular traffic, would provide a dramatic increase in visibility over the
signs and flags currently in use for this purpose. With its familiar stop sign shape,
its battery-powered arrays of color-coded LED lights, and its reversible configuration
— STOP on one side, SLOW on the other — the Safety Sign would warn
motorists, day or night, at far greater distances than conventional flags or signs.
• The Safety Sign would not only be visible from greater distance, but also
convey its cautionary warning in a shape that every motorist recognizes instantly.
The Safety Sign would be more visible in both daylight and night hours; during
foggy and rainy conditions — at all times and in all visibilities.
• The Safety Sign would protect work-crews on the roadway; children at a
school-crossing; police and EMS personnel handling an auto accident — and so
many more. The Safety Sign would also protect the personnel who hold it as a
signal — and the drivers who are to be controlled by its commands.
• Clearly, the Safety Sign is superior in every respect to its predecessors —
unlighted, poorly visible flags and signs. Cleverly conceived and thoughtfully designed,
the highly visible Safety Sign should find a sizeable market potential.
