BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to the field of law enforcement and, more particularly, to an improvement in the uniform epaulet-coupled emergency flashlight of my U.S. Pat. No. 6,015,217, issued Jan. 18, 2000.
2. Description of the Related Art
As my prior patent indicated, law enforcement, military police, corrections officers, border patrol, etc. usually carry flashlights of a type which can be grabbed by persons being questioned, and used as a weapon against an interrogating officer. My above patent described a flashlight which allowed the officer's hands to be free for use, and to enable the officer to react quickly to any attempt to injure or seriously place him/her in harm's way. Such flashlight then placed the officer at an advantage, rather than at a disadvantage.
As therein described, the flashlight was worn as part of a uniform, securable to a shoulder epaulet. A front end was rotatable upwardly and downwardly to generate and spread a light beam in use—or to be hooded closed, concealing the nature of the housing as an illuminating source when not being so employed. A flashing light was additionally included to illuminate through a back end as a rearwardly projecting beam in serving as a warning to oncoming motorists approaching from behind.
SUMMARY OF THE INVENTION
The present invention will be appreciated to extend the concept of this flashlight still further, in enhancing the quantity and quality of the light both forwardly and rearwardly, yet without increasing the size of the flashlight to any meaningful extent. At the same time, the flashlight of this invention will be seen to provide its operation in a variety of outdoor conditions—and especially in harsh environments where inclement weather conditions exhibited a tendency to rust or otherwise wear individual ones of the component parts of my earlier design. Realizing at the same time that uniforms worn by various law enforcement personnel both in the civilian and military fields oftentimes may differ, the flashlight of the present invention will be seen to be one in which a snug fit is insured on virtually every uniform design in use today.
Thus, and as will be seen from the description below, the enhanced uniform epaulet-coupled flashlight of the present invention incorporates a mirrorized reflector coupled with the front and rear lenses to increase and intensify visibility. At the same time, the single candle bulb utilized in generating the forward extending light beam of my prior construction is replaced by a plurality of ultra-bright light-emitting diodes (LEDs), while the halogen bulb utilized in generating the rearward extending beam is similarly replaced by a plurality of such LEDs—preferably of differing color combination to provide an increased observer awareness. Rechargeable nickel-metal hydride batteries are employed instead of double-A or triple-A alkaline batteries—preferable even to rechargeable ni-cad batteries. Additionally, and as will be seen, the rotating front lens which acted as an on-off switch for the flashlight itself is modified to be a 90° rotating head, instead of the 180° rotating head as in my earlier design—both for purposes of reliability in operation and so as to present less of a metal rotating clip in operation, which analysis has shown might rust or otherwise be adversely affected when used during rain, sleet, snow or similar inclement weather conditions.
Able to alert oncoming motorists of an officer's presence with a preferred stroboscopic light configuration in its rear, the flashlight of the present invention will be appreciated to be one offering upwards of 100,000 continuous hours of life without the need for a bulb replacement. When packaged along with an epaulet extender, the flashlight could then be secured with a wide variety of uniform designs.

DETAILED DESCRIPTION OF THE INVENTION
In
FIG. 1
, reference numeral
10
identifies a uniform shirt of the type worn by law enforcement personnel in the spring or summer, or a uniform jacket worn in the fall or winter, along with the shoulder epaulet
12
usually found at the shoulder
14
—and if not so included, then to be added there in accordance with the teachings of both this, and of my earlier, invention. As also shown, a flashlight
20
in a housing
16
is intended for placement within and under the epaulet
12
, with a fastener
18
simplified greatly at its top surface
21
to be secured to the epaulet when so inserted. Selected of dimension to fit within and under the epaulet
12
in a manner to be fastened to it as by a clip in a snug manner as to be further described, the housing
16
may be of generally rectangular cross-section. In a preferred embodiment, the housing
16
may be of a width “W” of the order of 1½-2½ inch and of a thickness “T” of the order of ¾-1 inch. Such housing
16
may be fabricated of plastic, or any other appropriate material, and of a length “L” of the order of 3-5 inches.
FIGS. 2-8
more particularly illustrate views of a preferred embodiment of the flashlight of the invention in assembled form. More specifically,
FIG. 2
illustrates a front perspective view of the housing
16
showing its front lens cover
30
, its securing clip
32
and an on-off switch cap
34
for energizing LEDs in generating a rearward extending beam.
FIG. 3
, on the other hand, is a rear perspective view of the housing
16
showing a rear lens
36
. A top view of the housing
16
is shown in
FIG. 4
, while a bottom view is shown in
FIG. 55
, where reference numerals
95
represent a pair of screws in fastening the housing together. The top cover of the housing is shown at
36
while the bottom cover is shown at
38
. A plurality of vent holes is provided in the bottom cover
38
, as at
97
. In the embodiment of the invention shown in
FIGS. 2-5
, the length “L” was selected to be 4.450 inch and the width “W” was selected to be 2.083 inch.
FIG. 6
is a end view looking at the front lens
30
of
FIG. 2
, while
FIG. 7
is an end view looking at the rear lens
36
of FIG.
3
.
FIG. 8
is a left side view of the housing
16
of
FIG. 3
with its front lens
30
open in a downward position, and with reference numerals
40
and
42
identifying a spring and a pin, respectively, for fastening the clip
32
to the epaulet
12
. A housing for the front lens
30
is shown at
44
for opening and hooding the front lens compartment. In the preferred embodiment of the invention, the overall thickness for the housing and the clip, shown as “T” was selected to be 1.127 inch.
FIGS. 9
a
-
9
c
are helpful in understanding some of the improvements of the flashlight of this invention as contrasted with that of my earlier design.
FIGS. 9
a
and
9
b
show the front lens “on-off” switch as being rotatable only 90° in exposing three ultra-bright light-emitting diodes
50
in providing thousands of continuous hours of life before the need for replacement. In
FIG. 9
a
, the LEDs
50
are exposed, while in
FIG. 9
b
, the LEDs
50
are hooded closed. Rotating the lens cover
44
from the position shown in
FIG. 9
b
to that shown in
FIG. 9
a
switches the LEDs
50
“on”, while rotating the lens cover
44
in the opposite direction turns the LEDs
50
“off”, besides hooding them.
FIGS. 9
a
and
9
b
also show three LEDs
52
,
54
,
56
behind the rear lens
38
to provide a stroboscopic effect when energized, as by the depressing the rear cap switch
34
of
FIG. 2
in actuating the plunger type control
58
of
FIGS. 9
a
and
9
b
, which rests beneath it. To heighten even more the stroboscopic effect, these LEDs
52
,
54
,
56
may be of differing colors, one from another, as by having the two outer ones illuminate “red”, and the inner one illuminate “white”.
FIG. 9
c
also shows a nickel-metal hydride rechargeable battery pack
60
, of 4.8 volt. As will be appreciated by those skilled in the art, nickel-metal hydride batteries are able to avoid many of the charging memory problems associated with nickel/cadmium rechargeable batteries, and exhibit an average one week's time of standard use once fully charged, before needing another charge. Recharging is by way of a standard pin shown as
62
in
FIG. 9
c
, accessible by removal of the cover
64
in
FIGS. 3
or
8
. As
FIGS. 9
a
-
9
c
illustrate, only the front cover
44
is rotatable in acting as the “on-off” switch for the illumination of the forward facing LEDs
50
, with a tapping of the cap
34
being sufficient to energize the rearward facing LEDs, and to then turn them “off”.
Pairs of mirrorized reflectors are added with the invention, coupled with the front and rear lenses to increase and intensify the visibility of the light emitting diodes employed. With
FIG. 10
a
representing a perspective view of these reflectors
80
, and
FIG. 10
b
and
10
c
representing top and bottom views respectively, the three apertures provided
82
are sized to encircle the LEDs in providing a further reflective surface for their illuminations. With the mirrorized coating being on the top surface
84
only, the end result is an intensification of the light beam generated downwardly on the paperwork being reviewed by an investigating officer, and an intensification even more of the rearwardly produced stroboscopic effect alerting the oncoming motorist. With the LEDs offering up to 100,000 continuous hours of life and more, and with the nickel-metal hydride batteries affording significant increases in battery life, a 30%-50% reduction in electrical consumption is further offered in enhancing operation.
Recognizing that not all uniform shirts or jackets may come with an epaulet of length to permit ready insertion of a flashlight of this type under it, the flashlight of the invention could be packaged along with an epaulet extender to ensure a snug fit on virtually every uniform. Such an extender is shown in
FIG. 11
, of approximately 1¼ inch length
90
and of an elasticized composition in allowing its opening
87
to receive the already present button on the uniform, and a button
89
to couple to the shirt or jacket.
While there has been described what is considered to be a preferred embodiment of the present invention, it will be readily appreciated by those skilled in the art that modifications can be made without departing from the scope of the teachings herewith. For example, in a manner similar to that set out with respect to the flashlight of my U.S. Pat. No. 6,015,217 design, the improved flashlight of this description could be used by emergency medical service technicians or by others besides law enforcement personnel. And, in similar manner, while the invention has been described utilizing light emitting diodes in groupings of “three”, other combinations can be employed, of either the same or differing colors in projecting a rearward beam stroboscopically or otherwise, and other than three light emitting diodes could be used in generating the forward extending beam in illuminating an area while permitting unfettered use of one's hands. Also, while mirrorized reflectors have been described as being highly advantageous when employed with both the forward and rearward facing plurality of light emitting diodes, either one could be eliminated and yet the flashlight still provide enhanced operation over that previously available. For at least such reasons, therefore, resort should be had to the claims appended hereto for a true understanding of the invention.
