Application No. 09/419,579
Cameron's power/control assembly 16 is provided with an elongate tubular
housing 28 for holding one or more batteries which supply electrical power to the
light/horn assembly 14. First and second finger actuated control buttons 30, 32 are
provided so as to enable the operator to selectively actuate the horn and flashing light
individually or simultaneously. Cameron's telescoping pole assembly 18 comprises an
extensible tubular support section 34 having a non-skid base 36 which rests on the
ground.
As shown in Figure 2A of Cameron, the audible/visible warning assembly 14
includes a housing 38 having a base ring 40 which threads onto or otherwise mounts to
the upper end of the tubular support rod 26. The upper portion of the housing provides
a base connection 42 for a warning light 44 having a domed plastic enclosure. The
audible warning signal is provided by a powerful horn unit 46 which is mounted in
housing 38, below the light 44. Preferably, the horn unit is at least bi-directional, i.e., it
faces outwardly from both sides of the side plate, and in some embodiments the horn
unit may be omni-directional. Cameron teaches (column 5, lines 18-23) that:
Although the placement of the visual and audible signals at the top of the
side assembly as shown in FIG. 2A has the advantage of increasing both
visibility of the light and the effective range of the horn unit, it will be understood
that numerous other placements may be used for these components.
