DETAILED DESCRIPTION




Referring now to the drawings and in particular to

FIGS. 1 and 2

, a multi-function flashlight


10


according to the present invention is shown. The flashlight


10


includes a lamp head


200


pivotally mounted to a body


20


. A ring clip


70


connected to the body


20


allows the flashlight


10


to be clipped onto a pocket or a belt. In addition, a saddle


150


mounts onto the ring clip


70


so that the light can be worn on the users head, or mounted on a helmet. The lamp head


200


includes a dual-parabolic-surface reflector


300


.




The general interconnection of the various components of the flashlight is shown more clearly in FIG.


2


. The body


20


is a generally cylindrical shell having a threaded open end for receiving a battery pack


100


. The battery pack


100


includes one or more batteries disposed in a battery casing


102


. The embodiment shown in

FIG. 2

includes four serially interconnected batteries


120


. A locking collar


90


threads onto the open end of the body


20


to secure the battery pack


100


in the body.




A mounting stem


30


on the end of the body


20


is formed for making a pivotable connection with and for mating engagement with a recess


237


formed in the lamp head


200


. A metallic pivot pin


180


extends through an opening in mounting stem


30


and a coaxial opening in the lamp head


200


to provide an electrical path between the body


20


and the lamp head


200


. A lamp socket


280


is mounted within the lamp head housing


205


for receiving two lamp elements


285


,


286


. Although both lamp elements can be incandescent bulbs, preferably lamp element


286


is an incandescent bulb, and lamp element


285


is a light-emitting diode (LED). Preferably, the LED lamp element


285


has a lower light intensity than the incandescent lamp element


286


so that the LED lamp element is operable to provide low level light intensity when such is desired. In addition, preferably the LED emits a non-white light such as red or green. A non-white LED allows the flashlight to be used in certain situations without significantly impairing the night vision of the operator.




The dual-parabolic-surface reflector


300


is mounted in the housing


205


so that the lamp elements


285


,


286


project through two openings found in the reflector. As is discussed further below, the reflector


300


has two parabolic reflecting surfaces: a minor concave reflective surface


306


nested within a major concave reflective surface


304


. In the embodiment shown, the incandescent lamp element


286


projects through the center of the major parabolic reflective surface, and the LED lamp element


285


projects from the center of the minor parabolic reflective surface.




A focusing ring


290


having internal threads


292


that engage with external threads


230


on the end of the lamp head housing


205


retains the reflector


300


within the housing. A coil spring


314


disposed between the lamp socket


280


and reflector


300


in coaxial relationship with the incandescent lamp element


286


biases the reflector away from the lamp socket so that the reflector is urged into contact with the focusing ring


290


. In this way, rotation of the focusing ring


290


displaces the reflector


300


relative to the lamp elements


285


,


286


. A gripping ring


295


is mounted in a circumferential groove


294


formed on the external surface of the focusing ring


290


.




Electrical energy is provided to the lamp elements


285


,


286


from the battery back


100


via a series of conductive contacts. Referring now to

FIGS. 9 and 10

, a positive battery conductor


145


connects a positive terminal of the battery pack


100


to the metallic pivot pin


180


. The pivot pin is connected to a lamp contact


160


against which one prong of each of the lamp elements


285


,


286


is maintained. A switch contact


170


is connected to a cylindrical conductive shell


185


that is coaxial with and located within the metallic pivot pin


180


. The conductive shell


185


is connected with a negative battery contact


146


of the battery pack


100


.




Referring back to

FIG. 2

, the circuit between the battery pack


100


and the lamp elements is controlled by the switch


250


, which has three operative positions. A switch contact


170


selectively contacts one or none of the second prongs of lamp elements


285


,


286


as switch


250


is moved to its various positions. In the first position, a switch contact


170


contacts the second prong of the first lamp element


285


to close the electrical circuit, so that the first lamp element is illuminated. In the second or off position, the switch contact


170


contacts neither of the lamp elements. In the third position, the switch contact


170


contacts the second prong of the second lamp element


286


, so that the second lamp element is illuminated.




Flashlight Body




Referring now to

FIGS. 2

,


11


and


12


, the details of the flashlight body


20


are shown more clearly. The flashlight body


20


has a hollow interior. The flashlight body


20


has end cap


25


that is preferably formed integrally with the sidewall of the flashlight body. The distal or open end of the flashlight body has external threads


28


formed thereon. A locking ring


90


has internal threads


92


formed therein for mating engagement with the external threads


28


.




Adjacent the end cap


25


, the flashlight body has circumferential groove


26


formed thereon for receiving the clip ring


70


. The groove


26


includes at least one detent


27


extending across the width of the groove which cooperates with ridges in the clip rings


70


as is discussed further below. The clip ring


70


includes a ring portion


72


that is dimensioned to fit within the groove


26


. A clip arm


74


extends from the ring portion


72


. The internal surface of ring


72


includes a plurality of parallel grooves


73


that engage with the detent


27


in the groove


26


. The engagement of a groove


73


with detent


27


prevents the ring portion


72


from easily rotating relative to the flashlight body. When sufficient force is applied to disengage the groove


73


from detent


27


, the clip ring


70


can be rotated to a desired position.




The clip arm


74


includes a pair of sockets


75


to facilitate the attachment of a mounting saddle


150


. The mounting saddle


150


is a removable device that allows the flashlight to be affixed upon a curved surface such as a helmet or an operator's head. As shown in

FIG. 11

, the saddle


150


includes a pair of saddle clips


156


having curved gripping ends. The saddle


150


is attached to the clip arm


74


by inserting the saddle clips


156


into the sockets so that the gripping ends of the saddle connectors engage the inside surface of the clip arm. The flashlight


10


is then mounted on a helmet. Once mounted on a helmet, the operator can direct a beam of light in a desired direction by turning and/or tilting his head. The saddle is attached to the operator's head or helmet by one or more straps. As shown in

FIG. 2

, the saddle


150


includes a plurality of strap slots


154


for that purpose. Straps are threaded through the strap slots and then wrapped around the operator's head or his helmet. The saddle


150


can also be affixed to a helmet with double-sided adhesive tape.




Preferably, the flashlight body


20


includes a grip sleeve around the outer surface of the body below the ring clip


70


. In the preferred embodiment, the gripping sleeve is made of an elastomeric material and has a plurality of parallel ridges to facilitate gripping the flashlight. However, the gripping sleeve can also have a smooth surface.




Referring now to

FIG. 10

, the end cap


25


of the flashlight body


20


includes an integral mounting stem


30


that is hollow. The mounting stem


30


has a stepped through-bore for receiving a hollow vent plug


40


. As seen in

FIG. 18

, the hollow vent plug includes a trilobal bore


42


through an inner wall thereof. The trilobal bore has a central bore


44


connecting three slots


42


extending through the inner wall of the hollow vent plug and directed radially relative to the central bore


44


. Vent plug


40


also has an external wall


47


that is contoured to maintain the curvature of the surface of stem


30


.




A flapper valve


55


is disposed in the central bore


44


of the vent plug


40


and extends through the inner wall of vent plug


40


. The hollow vent plug


40


has an open side


46


to facilitate insertion of the flapper valve


55


. The vent plug is press-fit into the stepped bore of the mounting stem so that the vent plug abuts a shoulder in the stepped bore. The flapper valve


55


includes an enlarged head


56


that engages the inner surface of the vent plug to form a seal over the trilobal, bore


42


. The flapper valve


55


includes a stem


59


connected to the enlarged head, which passes through the central bore of the vent plug


40


. An integral barb


58


on the stem


59


is formed on the outer surface of the stem


59


to fix the flapper valve in place on the vent plug. Two passageways extend through the end cap


25


so that the inside of the flashlight body communicates with the stepped bore of the mounting stem


30


. Gases produced by use of the batteries pass through those passageways and then through the trilobal bore in the vent plug


40


. When the gas pressure reaches a threshold level, the head


56


displaces and the gases are vented from the flashlight. In this manner, the flapper valve functions as a one-way valve that allows the release of gases produced from use of the batteries, while preventing fluid from entering the flashlight.




Each of the passageways between the body and the mounting stem are configured to receive one of the two battery contacts


145


or


146


. As shown in

FIG. 10

, the battery contacts


145


and


146


are fixed in place in the passageway by barbs


148


and


149


on the respective contacts. Prior to inserting the battery contacts


145


and


146


into the passageway, a deoxidizing pellet


38


is placed in a recess in end cap


25


. When inserted in its passageway, the negative battery contact


146


is positioned to maintain the deoxidizing pellet in the recess.




Battery Pack




Referring again to

FIGS. 2

,


9


,


11


and


12


, the battery pack


100


includes a case


102


having a closed end


105


and an open end for receiving one or more batteries


120


. When assembled, the open end is sealed by an O-ring


130


and an end cap


125


that is removably connected to the casing by two screws


135


,


136


that extend through the end cap and into the body of case


102


. The batteries


120


can be either disposable or rechargeable. In the preferred embodiment, the batteries


120


are rechargeable batteries that are serially connected to one another by a plurality of battery connector straps


118


. One of the battery straps is connected to a thermal fuse and a diode, which are not shown, and is engaged by the central screw


135


that attaches the end cap


125


to the housing


102


. A second battery connector strap is engaged by the side screw


136


that connects the end cap


125


to the casing


102


. The battery strap that engages the center screw


135


is separated from the battery strap that engages the side screw


136


by an insulator


142


. The center screw


135


and the side screw


136


are electrically connected to the batteries


120


and act as terminals for recharging the battery


100


.




The closed end


105


of the case


102


has an annular flange that is slightly smaller than the inner diameter of the flashlight housing


20


. Two holes


108


in the closed end


105


provide access ports for the battery contacts


145


and


146


to contact the respective positive and negative terminals of the battery pack. A recess


107


in the edge of the closed end


105


cooperates with an axially elongated alignment rib


85


projecting from the inner surface of the flashlight body


20


. The alignment rib


85


acts as a key to align the battery pack


100


to ensure that the battery pack is properly oriented within the flashlight housing. The casing


102


further includes an external rib


104


that cooperates with a latch in a recharger


400


used to recharge the battery pack as described below.




The battery pack


100


is secured within the flashlight housing


20


by a locking ring


90


having internal threads that engage with the external threads


28


of the flashlight body. The locking ring urges the end cap


125


of the battery pack


100


against O-ring


130


that engages the end of the flashlight body to provide a fluid-tight seal.




The Lamp Housing




Referring now to

FIGS. 2

,


8


and


9


, the details of the lamp head


200


are seen more clearly. The lamp head includes a housing


205


that is pivotally connected to the mounting stem


30


of the flashlight body


20


. The housing


205


includes a pair of mounting posts


210


onto which the lamp socket


280


and the lamp contact


160


are mounted. The posts


210


project through holes formed in the lamp socket and the lamp contact respectively. The posts are flared by applying heat and pressure to the ends thereof to retain the lamp socket


280


and the lamp contact


160


in place. The lamp housing


205


further includes an aperture


242


through which the switch


250


projects. Arcuately spaced pairs of parallel ribs


235


are disposed around the inner circumference of lamp housing


205


to serve as guides for mounting the reflector


300


and positioning relative to the lamp elements


285


and


286


.




The electrical and mechanical interconnection between the flashlight body


20


and the lamp head


200


is shown more clearly in FIG.


10


. The first mechanical and electrical connection between the lamp head


200


and the flashlight housing


20


is provided by a hollow metallic pin


180


. The hollow pin


180


has a flanged head at one end thereof. The hollow pin


180


extends through the stepped bore in the mounting step


30


of the body, through a hole in the positive battery contact


145


, through an aperture in the lamp head housing, and finally through an aperture in the lamp contact


160


. The flanged head of hollow pin


180


abuts the wall of stem


30


surrounding the stepped bore to prevent the hollow pin from sliding therethrough. The other end of the hollow steel pin


180


is crimped over onto the lamp contact


160


to fix the pin in place. In this way, the hollow pin


180


provides a pivotal connection between the lamp head


200


and the flashlight body


20


, as well as an electrical connection from the positive battery contact


145


to the lamp contact


160


. An O-ring


198


disposed between the lamp head


200


and the mounting stem


30


provides a fluid-tight seal between the lamp head and the flashlight body


20


.




A spacer sleeve


190


, which may be formed of an electrically insulating material, is disposed coaxially through the hollow pin


180


. Spacer sleeve


190


has a flange formed at one end thereof. A second hollow metallic pin


185


extends coaxially through the spacer


190


. The pin


185


extends through an aperture in the negative battery contact


146


and a spring washer


194


. The inner pin


185


has a flanged head that engages a conductive washer


192


which contacts the switch contact


170


. To fix the inner pin


185


in place, the non-flanged end thereof is crimped against the flanged head of the spacer


190


. The insulator spacer


190


supports the crimping forces that are applied to the inner pin


185


so that the crimping forces are not transferred to the outer pin


180


, which could adversely affect the interconnection between the lamp head


200


and the flashlight body


20


. The washer


192


provides an increased surface area to distribute the reaction forces associated with the crimping of the inner pin


185


against the flanged head of the insulator sleeve


190


. The inner hollow pin


185


provides an electrical connection between the switch contact


170


and the negative battery contact


146


. A sealing plug


50


is disposed in a recess in the side of the lamp housing


205


. The recess provides an access port for inserting and crimping the inner and outer hollow pins


180


and


185


.




The lamp head


200


includes two lamp elements


285


and


286


that are mounted in the lamp socket


280


. Referring now to

FIGS. 15 and 16

, each lamp element


285


,


286


includes two prongs


288




a,




288




b,


and


289




a,




289




b,


respectively. The lower prongs


288




b,




289




b


of the lamp elements contact the lamp contact


160


. The upper prongs


288




a,




289




a


are normally spaced from two resilient arms


176


and


177


of the switch contact


170


. The arms


176


and


177


are resilient and cooperate with the switch


250


.




The switch


250


includes a rotatable shaft having two eccentric lobes


262


and


264


. As noted previously, the switch


250


operates in three positions. As shown in

FIG. 17

, the second or off position is illustrated. In the off position, the eccentric lobes


262


,


264


do not urge either of the switch contact arms


176


,


177


into contact with the lamp element prongs. Rotating the switch


250


in the direction of arrow A causes the eccentric lobe


262


to engage the second contact arm


177


and force it into contact with prong


288




a


of lamp element


285


. At the same time, eccentric lobe


264


is rotated away from the second switch contact arm


176


so that the second contact arm does not contact prong


289




a


of lamp element


286


. When switch


250


is rotated in the direction of arrow B, eccentric lobe


264


forces the first contact arm


176


into contact with the second prong


289




a


of lamp element


286


. In this way, the switch operates to control the illumination of lamp elements


285


and


286


independently of one another.




Referring now to

FIGS. 8 and 12

, the switch


250


is mounted in the aperture


242


in the base of the lamp housing


205


. A plurality of resilient switch-holding fingers


240


engage an annular groove in the switch to retain the switch in the lamp housing. In addition, an O-ring is disposed between the switch


250


and the lamp housing


205


to provide a fluid-tight seal between the switch and the lamp housing.




Referring to

FIGS. 11 and 13

, the reflector


300


has a pair of apertures


308


and


309


formed therein for receiving the light elements


285


and


286


. The lamp elements


285


and


286


project through the apertures


308


and


309


as described hereinabove. The reflector includes two parabolic reflecting surfaces. The first is a major parabolic reflective surface generally symmetric about an axis through the central aperture


308


. Nested within a sector of the major parabolic surface is a second minor parabolic reflecting surface


306


that is generally symmetric about an axis through the aperture


309


. In this way, the reflector


300


incorporates a smaller reflective surface


306


nested within a larger reflective surface


304


. The major parabolic reflective surface


304


provides a reflective surface for the central lamp element


286


and the minor parabolic reflective surface


306


provides a reflective surface for the second lamp element


285


. Because of this unique configuration, the minor reflective surface


306


does not substantially interfere with the reflection of the light from lamp element


286


off of the major reflective surface


304


.




An O-ring


299


is disposed between the lamp housing


205


and the focusing ring


290


to provide a fluid-tight seal between the focusing ring and the lamp housing. In addition, as shown in

FIGS. 11 and 12

, the focusing ring


290


includes an integral lens


298


.




Battery Charger




Referring now to

FIGS. 19-21

, a battery charger


400


for recharging the battery back


100


in the flashlight


10


is shown. The battery charger


400


includes a housing


410


having a receptacle


415


extending from the top surface of the housing for receiving the contact-end of the flashlight. Alternatively, the socket


415


can be configured so as to receive only the battery pack


100


instead of the entire flashlight


10


. A latch


430


is provided to retain the flashlight or battery pack in the socket


415


. In the embodiment shown, the latch


430


is configured to cooperate with an annular groove


96


found in the locking ring of the flashlight (see FIG.


2


). If the socket


415


is configured to receive the battery pack


100


, the latch


430


is preferably designed to cooperate with the retaining rib


104


located on the external surface of the battery case


102


, also shown in FIG.


2


.




The latch mechanism includes a lever arm


434


pivotally mounted to the wall of receptacle


415


by a pivot pin


439


. A latching finger


437


projects from the distal end of the lever arm


434


to engage the annular groove


96


in the locking ring


90


or the locating rib


104


on the battery case


102


. A coil spring


432


biases the proximal end of the lever arm


434


, thereby urging the latching finger


437


about the pivot pin and into contact with the flashlight or the battery pack.




To recharge the batteries, two terminals in the battery charger are positioned for contacting the heads of the screws


135
