Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] Applicant claims the priority benefits of U.S. provisional
Patent Application No. 61/595,377, filed Feb. 6, 2012.
BACKGROUND OF THE INVENTION
[0002] This invention relates to lighting devices, and in
particular, to safety lighting devices for providing a warning or
alert to persons or vehicles within the vicinity of the lighting
device.
[0003] At an incident, such as a traffic accident, an individual
usually distributes a plurality of road flares on the road as a
temporary divider or warning on a roadway. The road flares alert
other drivers that there is an accident or other incident in front
so as to separate the accident/incident from the roadway. One of
the most common road flares is the ignition type disposable flare
wherein the flare is simply ignited and directly disposed on the
roadway. However, conventional ignition type flares have several
drawbacks. Such flares are a fire hazard, not to mention a hazard
to the individuals using them. Once a flare has been ignited, it is
not safe for an individual to move or relocate it. The individual
could burn their clothes, or their skin, or injure others.
Moreover, combustible flares could ignite spilt fuel or dry brush
along a roadside. Moreover, the usable time of the flare depends on
the burning rate of the flare. If the user finishes the need for
the flare before the flare is used up, the flare must be left on
the roadway until the flare is totally burnt. If the user requires
longer time for emergency lighting, another flare must be
ignited.
[0004] Accordingly, there remains a need for a visual signal device
that will operate to not only aid emergency personnel to locate an
emergency site, but to provide a warning of an emergency condition.
Moreover, it is desirable that the signal device be durable,
environmentally safe, available at a reasonable cost and compact in
size and operate to unequivocally signal an emergency condition.
Furthermore, the signal device must have the capability to be
easily turned on and off.
SUMMARY OF THE INVENTION
[0005] The present invention solves some of the aforementioned
problems by providing an emergency signaling device that is simple
in construction yet durable and safe to use. Another object of the
present invention is to provide an emergency signaling device that
is reliable, easily deployed, easily recovered after use, is water
resistant, and easily turned on and off. Features of the present
invention include the use of a battery-operated light emitting
diodes pulsed at a predetermined rate, said diodes being placed
adjacent reflective material to extend or direct the light pulsing
from the diodes. The emergency signaling device includes metallic
bars to assist in magnetic recovery of the devices after use.
[0006] The present invention also includes a deployment pack
attached to an emergency vehicle, said pack holding a number of
emergency signaling devices and adapted to deploy said devices
quickly and efficiently. The deployment pack allows a person to
deploy illumination devices without being exposed to dangerous
conditions. The user may then deploy the illumination devices to
mark the road without being subjected to the dangers of oncoming
traffic.
[0007] These together with other objects of the invention, along
with various features of novelty which characterize the invention,
are pointed out with particularity in the claims annexed hereto and
forming a part of this disclosure. For a better understanding of
the invention, its operating advantages and the specific objects
attained by its uses, reference should be had to the accompanying
drawings and descriptive matter in which there is illustrated a
preferred embodiment of the invention.

flare 10 according to the principles of the present invention. The
flare 10 is generally rectangular and has a top edge 11, bottom
edge 12, two opposite side edges 13, an upper planar surface 14,
and an opposite under planar surface 15, said edges and surfaces
defining a flare interior 16. The upper and under surfaces 14, 15
each have an annular central transparent area 17. The flare 10 is
generally flat having a uniform thickness between upper and under
surfaces of approximately 0.5 inches.
[0017] The flare interior 16 contains two generally annular,
concave reflectors 20, centrally located, each reflector 20 opening
onto a said surface central transparent area 17. Each reflector 20
has a light emitting diode (LED) 22 positioned at the reflector
vertex 21. The LEDs 22 are electrically connected to a flasher
circuit 23 which pulses the LEDs at a predetermined rate. The LEDs
22 and flasher circuit 23 are electrically connected through a
switch 24 to a rechargeable battery 25. The battery 25 also has two
leads connected to two external metal elements 27 attached
externally to the flare bottom edge 12. The external metal elements
27 provide means for externally charging the battery 25.
[0018] The flare interior 16 also contains two parallel, metallic
rods metal rods 26, parallel to and near to said flare opposite
side edges 13. The metallic rods 26 provide means for flare
retrieval by a magnetic pick-up tool (not shown), such as sold
under the AMK Manufacturing Roadmag brand. These magnetic pick-up
tools are typically suspended beneath a clean-up vehicle, such as a
highway department truck, used after accidents wherein the
suspended magnet picks up nails, wire and other metal objects that
can damage tires or injure people. The capability of magnetically
recovering the present invention flare is unique to the present
invention.
[0019] The present invention also provides a case 30 for holding a
plurality of electric road flares 10. The case 30 is a generally
rectangular with a pivotal, lid top 31, a bottom 32, a rear side
33, a front side 34, two opposite sides 35 interconnecting said
front and rear sides, said top, bottom and sides defining a case
interior 36. The case front side 34 has a generally rectangular
aperture 37 formed therein, said front aperture extending from
opposite side to opposite side, near to the bottom 32 toward the
top 31 a predetermined distance. The case interior 36 has two
parallel conductive strips 40 along one of said opposite sides 35',
extending from near the case bottom 32 toward the case top 31, each
of said conductive strips having an electrical lead 41 attached
thereto and extending through an aperture 38 in the case rear side
33. The case interior 36 also has a switch activation strip 42
along the same side 35' as the conductive strips 40, said switch
activation strip 42 being located between said conductive strips 40
and extending from near said case bottom 32 a predetermined
distance toward the case top 31.
[0020] The case pivotal top 31 has a spring 43 attached thereto,
said spring extending downward into the case interior 36. The
spring terminates in a flat element flat element 44. The case top
has a latch mechanism 45 to hold the top lid in closed position.
The case interior 36 two, elongated parallel rotating elements 46,
47 contained therein. The rotating elements each have a
longitudinal axis extending from case side 35 to case side 35',
each said rotating element longitudinal axis being parallel to the
case front and rear sides. The rotating element 46 nearest the case
rear 33, is free wheeling. The rotating element 47 nearest the case
front 34 has an electrical drive element 48 electrically connected
by a lead 49 interconnected through the case rear 33 to the
emergency vehicle 1 described below. The case 30 is adapted to hold
a plurality of electric road flares 10 resting on said rotating
elements 46, 47 and held in position by the lid flat element 44.
The electric road flare 10 at the bottom of the stacked flares is
adjacent the front side aperture 37.
[0021] The case rear 33 has a hitch attachment element 39 fixedly
attached thereto, said hitch attachment element adapted to
removably attach said case 30 to the tow hitch 3 on the rear end 2
of an emergency vehicle 1 such as a police cruiser. The electrical
leads 41, and 49 from the case attach to the battery of the
emergency vehicle.
[0022] In operation, the case interior 36 is loaded with a
plurality of flares 10. The case 30 is attached to the emergency
vehicle hitch 3. Each flare is positioned in the case interior 36
so that a flare bottom edge 12 is positioned against the case
opposite side 35' with the conductive strips 40, wherein the flare
bottom edge metal elements 27 are electrically engaged with the
conductive strips 40. The flare switch 24 is set to the off
position so that the flare LEDs 22 and flasher 23 are inactive.
However, the flare battery 25 is in a charging mode from
electricity from the emergency vehicle batter through the
electrical leads 41 and conductive strips. When the emergency
vehicle arrives at an emergency site, the drive roller 47 at the
bottom of the case is activated sliding the bottom most flare 10
out through the front aperture 37 onto the emergency site. As each
flare moves downward, the switch activation strip 42 activates the
flare switch 24 before the flare is ejected from the case.
[0023] It is understood that the above-described embodiment is
merely illustrative of the application. Other embodiments may be
readily devised by those skilled in the art which will embody the
principles of the invention and fall within the spirit and scope
thereof.
