Abstract
A dual mode rechargeable flashlight includes a generally rectangular housing sized to be readily carried and operated in one's hand and having a pair of upper and lower frame members that receive and retain generally planar rectangular panels preferably made of anodized aluminum and which may be of selective colors and have indicia imprinted thereon. An integral charging system within the flashlight housing enables recharging of DC batteries connectable in circuit with a high intensity lamp carried within a reflector assembly at a forward lens end of the flashlight. A modular self-storing blade assembly facilitates connection of the charging system to an electrical outlet. A power pack support housing within the flashlight is accessible through an access door to enable insertion of a 6-volt DC battery power pack connectable in circuit with a high intensity long life LED carried within the reflector assembly. Selective actuation of a switch button effects energizing of either the high intensity lamp or the high luminous intensity LED.
Description
FIELD OF THE INVENTION
The present invention relates generally to flashlights, and more particularly to a small size hand holdable flashlight selectively operable in a dual mode so as to energize a high intensity Xenon bulb through a rechargeable battery power source or to energize a high intensity LED.
BACKGROUND OF THE INVENTION
Conventional general-purpose flashlights are well known and find wide application by both law enforcement personnel and civilians. Conventional flashlights generally include an incandescent light bulb and dry cell batteries disposed in an elongated tubular casing typically consisting of a body section and a head section. Flashlights of this type are often bulky and cumbersome. The size and weight of such conventional flashlights inhibit the mobility of law enforcement personnel when carried along with other law enforcement equipment, and sometimes leads to the flashlight being purposely or inadvertently left behind. This presents a problem when the need for a flashlight arises and one is not readily accessible. Similarly, for personal use lighting, conventional bulky flashlights do not lend themselves to being carried at times when conditions suggest that a flashlight be carried on one's person in the event one loses his/her way during walking or hiking in unfamiliar territory, or when backpacking and camping where the weight of equipment is a significant factor. Even in home use, a conventional bulky flashlight is generally kept in an inconspicuous place so that in time of emergency, or in impending situations where it is known that a flashlight may be needed, it is not convenient to retrieve the flashlight and carry it on one's person.
Due the very nature of flashlights that employ dry cell batteries, there comes a time when the batteries are virtually exhausted or discharge and do not maintain the associated light bulb with sufficient energy to create a worthwhile beam of light. In this instance, it would be highly desirable to have a second discrete high intensity source of light that could be used for a temporary period of time and has a long life power source due to low voltage requirements of the high intensity light, can provide lighting until either the batteries for the primary high intensity bulb can be replaced or recharged.
Flashlights are known that carry rechargeable batteries that can be recharged without removing the batteries from the flashlight. Moreover, flashlights are known that employ two bulbs with one bulb being in a backup circuit in the event the first bulb expires by burning out. These known flashlights, however, exhibit a disadvantage in that they are relatively bulky and heavy and do not lend themselves to being readily carried on one's person for significant periods of time. Accordingly, a flashlight that is of small size so as to be readily carried in the palm of one's hand, and that can also be carried in a small case or the like carried on one's belt or in a pocket, and that further employs a high intensity bulb energized by rechargeable batteries internally of the flashlight and chargeable without removal from the flashlight, as well as having a high intensity LED powered by a modular replaceable power pack, would offer significant advantages over the prior known flashlights.
BRIEF SUMMARY OF THE INVENTION
One of the primary objects of the present invention is provide a dual mode rechargeable flashlight of relatively small size that can be readily carried on one's person.
A more particular object of the present invention is to provide a dual mode rechargeable flashlight that is operable in a first mode to activate a brilliant Xenon lamp in a first position of a switch button on the flashlight, and energize a long life solid state LED beam that creates a highly visible light responsive to movement of the light switch to a second position effecting a second mode of operation.
Another object of the present invention is to provide a small hand holdable flashlight having the aforedescribed characteristics but also having a modular self-storing blade assembly that is normally self-storing within the flashlight housing and can be removed and rotated to facilitate connection to an electrical receptacle for charging a rechargeable power source within the flashlight.
Still another object of the present invention is to provide a relatively small flashlight having a generally rectangular housing that can be readily held within the palm of one's hand and that provides dual mode operation of either a high intensity Xenon bulb through a rechargeable battery charging system without removing the batteries from the flashlight, and that also has a high intensity LED energized by a modular replaceable power pack carried in the flashlight housing in response to selective movement of a switch exposed externally of the flashlight housing.
Still another object of the present invention is to provide a relatively small compact flashlight as aforedescribed employing a polycarbonate lens having a curvature such that energizing the high intensity LED enables the flashlight to be observed from a substantial distance from the user, as well as being observed from a position disposed approximately 90° from the axis of the flashlight.
A feature of the flashlight in accordance with the present invention lies in the utilization of a flashlight frame adapted to support panel members that may be of different colors than the flashlight frame so as to provide an aesthetically attractive flashlight.
Another feature of the present invention lies in providing a small size flashlight as aforedescribed wherein the panel members facilitate printing or other indicia being placed on the exposed surfaces of the panels to provide a personal and pleasing inscription or promotional inscription.
A further feature of the flashlight in accordance with the present invention lies in the combination within the flashlight of a power pack receiving housing for supporting a power supply to a high intensity LED upon selective actuation of a switch, and which also has a rechargeable battery source and means for charging the battery source as a component of the flashlight without removing the batteries from internally of the flashlight housing.
Still another feature of the flashlight in accordance with the present invention lies in the ability to utilize either a battery recharging module for use with electrical receptacles in the United States, or a modular adaptor enabling recharging with receptacles as in many countries outside the United States.
Still another feature of the flashlight in accordance with the present invention, lies in the provision of a relatively compact small flashlight housing that employs generally rectangular frame members and associated rectangular panels and that are mutually cooperable to establish a flashlight housing along the periphery of which a trim belt may be applied that protects the housing and improves frictional contact between the user's hand and the flashlight.
Further objects, advantages and features of the present invention will become apparent from the following detailed description taken in conjunction with the accompanying drawing wherein like reference numerals designate like elements throughout the several views.

DETAILED DESCRIPTION OF THE INVENTION
Referring now the drawings, and in particular to
FIGS. 1-4
, a flashlight constructed in accordance with a preferred embodiment of the present invention is indicated generally at
50
. As will be described, the flashlight
50
is operative in a dual mode to enable selective energizing of a high intensity lamp by a rechargeable power source, or energizing of a long life LED crystal light through a power supply in the form of a replaceable battery pack.
Briefly, the flashlight
50
includes a generally rectangular housing, indicated generally at
52
, sized to be readily carried and operated in one's hand. For example, one embodiment utilizes a rectangular housing having a longitudinal length of approximately about 4 inches, a transverse width of approximately about 1⅝ inches, and a thickness of approximately about ¾ inches. The housing
50
is defined by laterally spaced sides
54
and
56
that intersect a top surface
58
, a bottom surface
60
a transverse rear surface
62
and a front lens light emitting end
64
. It will be understood that reference to the “top” and “bottom” surfaces
58
and
60
are for purposes of description only, and that the flashlight
50
may be readily operated with the top surface
58
facing downwardly or in a inclined direction when grasped in a user's hand.
With particular reference to
FIG. 4
, the housing
52
includes a pair of upper and lower frame members
68
and
70
, respectively, that are preferably made of a molded polycarbonate material. Each frame member
68
and
70
has a generally rectangular opening therein, as indicated at
68
a
and
70
a
, respectively, sized and configured to receive and retain generally planar panels
72
and
74
, respectively. The panels
72
and
74
are preferably made of a forged anodized aluminum and are adapted to have predetermined colors applied thereto or have other indicia imprinted thereon or emblems attached thereto.
The frame members
68
and
70
, together with their respective panels
72
and
74
, are adapted to be connected in mutually engaging relation so as to define an internal chamber or cavity that receives and supports an integral charging system, indicated generally at
80
. The housing
50
also carries an internal housing for releasably receiving a power source in the form of a DC battery power pack
82
. The housing
50
supports a parabolic reflector and light source assembly, indicated generally at
84
, and a high impact polycarbonate outwardly convexly curved lens
86
on the forward light-emitting end of the housing. The housing formed by the frame members
68
and
70
and the associated panels
72
and
74
is adapted to receive a modular self-storing blade assembly, indicated generally at
88
, within the rear end of the housing. As will be described, the self-storing blade assembly
88
facilitates connection of the integral charging system
80
to an electrical outlet to charge a rechargeable power source for a high intensity 3-volt lamp, such as indicated at
90
in
FIG. 4
, through a suitable AC to DC rectifier. An access door or cover
92
is pivotally connected to the rear end of the housing
52
so as to cover an access opening in a power pack receiving housing while facilitating exposure of the power pack receiving housing to facilitate replacement of a battery pack.
Turning now to a more detailed description of the various components of the flashlight
50
, and in particular in
FIGS. 5-11
, the upper frame member
68
preferably has an upper surface
68
b
that is slightly upwardly curved or convex, as considered in transverse cross section, and has substantially parallel radiused longitudinal marginal edge surfaces formed integral with downwardly depending generally planar wall portions
94
and
96
. As illustrated in
FIG. 6
, the wall portions
94
,
96
have semi-circular recesses
94
a
and
96
a
, respectively, formed along their lower marginal edges. Each wall
94
and
96
has a plurality of integral preferably cylindrical-shaped guide pins, indicated at
94
b
and
96
b
, respectively, that are adapted for cooperating relation with the lower frame member
70
to facilitate a predetermined assembled relation therewith. The forward end of the upper frame member
68
has a rectangular opening
98
therethrough adapted to receive a manually operable switch actuating button or knob as indicated at
100
in FIG.
1
. The forward end of the upper frame member
68
also is formed with a generally convex edge curvature
68
c
that establishes laterally spaced concave profile edge surfaces, such as indicated at
68
d
in FIG.
6
.
The lower frame member
70
is generally similar in configuration to the upper frame member
66
but has a rectangular opening
70
a
of greater longitudinal length than the rectangular opening
68
a
in the upper frame member. The lower frame member
70
has an overall longitudinal length equal to the longitudinal length of the upper frame member
68
and has a transverse width equal to the transverse width of the upper frame member
68
. The lower frame member
70
has rounded or radiused longitudinal marginal edges similar to the upper frame surface
68
that terminate in generally planar parallel walls
102
and
104
having upper marginal edges
102
a
and
104
a
, respectively, dimensioned to abut the lower marginal edges of the walls
94
and
96
of the upper frame member when assembled therewith. In similar fashion to the upper frame member
68
, the walls
102
and
104
of the lower frame member have semi-circular recesses
102
b
and
104
b
, respectively, formed in spaced relation along the upper marginal edges
102
a
and
104
a
so that when the upper and lower frame members are in assembled relation, the semi-circular recesses are matched to form circular openings in the sides of the resulting frame. As illustrated in
FIG. 10
, the walls
102
and
104
of the lower frame member
70
have pairs of guides
102
c
and
104
c
that establish slots to receive the guide pins
94
b
and
96
b
on the upper frame member so as to effect the desired assembled relationship between the upper and lower frame members.
In similar fashion to the upper frame member
68
, the lower frame member
70
also has a mildly curved convex lower surface
70
b
which terminates at its forward end in a convex edge surface
70
c
similar to the convex edge surface
68
c
of the upper frame member. Similarly, the forward edge surface
70
c
on the lower frame member establishes concave laterally spaced edge surfaces
70
d
that are mirror images of the concave curved surfaces
68
d
on the upper frame member. Referring to
FIGS. 10 and 11
, a pair of generally L-shaped walls
108
a
and
108
b
are formed on the rearward end of the lower frame member
70
and cooperate with components of the integral charging system
80
to assist in providing a generally rectangular shaped closed recess within the rear end of the flashlight to receive the modular self-storing blade assembly
88
, as will be described.
FIGS. 12-14
illustrate a panel member that is representative of both panel members
72
and
74
. For purposes of illustration, the panel member illustrated in
FIGS. 12-14
will be referred to as the upper panel member
72
. The panel member
72
is generally rectangular and has an outer rectangular marginal edge
72
a
that is sized so as to fit within the rectangular opening
68
a
in the upper frame member
68
with the outer marginal edge of the panel slightly underlying the periphery of the rectangular opening
68
a
. The upper frame member is provided with a lip peripherally of the opening
68
a
that accommodates and cooperates with the outer marginal edge
72
a
of the panel
72
so as to retain the panel within the upper frame
68
without need for an adhesive. The panel
72
has a generally planar rectangular surface area
72
b
that is spaced above the plane of a lower rectangular marginal edge
62
c
of the panel so that the upper surface
72
b
will extend slightly outwardly from the frame member
68
when in assembled relation therewith.
As noted, the panel
74
that is received within and supported within the rectangular opening
70
a
in the lower frame member
70
is of substantially the same configuration as a representative panel illustrated in
FIGS. 12-14
except having a longer longitudinal length so as to fit snugly within the rectangular opening
70
a
. The panels
72
and
74
, which may alternatively be termed top and bottom covers, are preferably made of anodized aluminum, but may also be made of other suitable rigid metals, rubbers, and plastics. Preferably the side panels are made of anodized 6061 aluminum that provides the desired strength and is easily colored for desired eye appeal or contrasting with the color of the polycarbonate frame members
68
and
70
. Anodized aluminum can also be easily engraved or imprinted, silk screened, inked, pad printed, or marked in any known manner.
As aforedescribed, when the upper and lower frame members
68
(
FIG. 4
) and
70
are assembled in mutually overlying relation, circular openings are formed along the laterally spaced sides of the resulting assembly defined by the semi-circular recesses
96
a
and
104
b
, respectively, in the upper and lower frame members, as illustrated in
FIGS. 4
,
6
, and
9
. The resulting circular openings or holes facilitate attachment of a pair of elongated trim belts, one of which is indicated at
110
in
FIGS. 4
,
15
, and
16
, along the sides
54
and
56
of the flashlight housing
52
. The belt
110
is of a transverse width to be received within a longitudinal recess established between longitudinal marginal edge surfaces
96
c
and
102
d
, respectively, formed on the upper and lower frame members
68
and
70
when in assembled relation, as illustrated in
FIGS. 4
,
6
, and
9
. The trim belt
110
is preferably made of a resilient material, such as rubber, and has a slightly convex outer surface
110
a
and a generally planar inner surface
110
b
along the longitudinal center axis of which is formed a plurality of spaced headed bosses
112
from the resilient belt material. The bosses
112
are positioned and sized for insertion within the circular openings formed along the sides of the assembled upper and lower frame members
68
and
70
. Each of the trim belts
110
has a generally 90° curved end portion
110
c
on the inner surface of which is formed a pair of inwardly directed integral bosses
114
sized to be received within corresponding openings formed in the assembled upper and lower frame members
68
and
70
so as to wrap around curved rear comers of the assembled frame members. A small opening or hole
116
is formed in each of the trim belts
110
at a position to overlie an opening in each depending wall
94
and
96
of the upper frame members
68
and
70
, as indicated at
96
d
in FIG.
6
and enable entry of a small diameter rod, such as the straightened end of a paper clip, to facilitate release of the lens
86
from the flashlight housing. The trim belts protect the housing sides from abrasion and also provide a comfortable improved gripping for the flashlight.
Referring to
FIG. 17
, the integral battery charging system
80
includes a generally rectangular rigid circuit board
120
having a pair of generally rectangular openings
120
a
and
120
b
