Application No. 09/419,579
Figure 2B shows a second embodiment of the invention in which each display
surface of the sign plate (only the first display surface 22a being shown in FIG. 2B) is
provided with a plurality of spaced apart flashing light units. The position of the horn
unit 52 may be at any suitable location in this embodiment, with a position near the
upper part of the sign being prefered again for achieving maximum projection.
Figure 7 shows a hand-held sign assembly 140 which lacks the telescoping pole
assembly described above. The hand-held sign assembly 140 includes power/control
assembly 142 which is substantially similar to the corresponding assembly 16 described
above, having finger operated control buttons 30, 32. The power/control assembly 142,
which is sized to be conveniently held in one hand, is connected to a combined
visual/audible warning assembly 144 by means of a male/female coupler pair 146. In
this embodiment, however, the visual/audible warning assembly 144 is preferably
positioned at the base of the sign plate 20 so as to provide the assembly with better
balance for hand-held use. The light unit includes a single strobe light 150 which
illuminates both sides of the sign, through an opening in plate 20. On the "STOP" side,
the light unit is provided with a red lens 152, while the opposite side of the sign plate
(having the "SLOW" legend) has an amber lens. The horn unit 154, in turn, is
substantially similar to that described above with reference to Figure 2A, and is
