Abstract
A light device having a battery and lamp housing and a hinged top door. Batteries and a lamp holder are located within the housing and are accessible by opening the hinged top door. As the hinged top door is opened, a cam surface that holds the batteries in tight contact with the lamp holder moves away from the batteries, thereby releasing the tension holding the batteries in place within the housing. The batteries can therefore be easily loaded and unloaded. Likewise, as the hinged top door is closed, the tension holding the batteries in place is reapplied to the batteries to create a circuit for powering a lamp engaged with the lamp holder. Furthermore, the lamp engaged with the lamp holder is also accessed through the hinged top door.
Description




BACKGROUND OF THE INVENTION




The present invention relates to lighting devices, and in particular to a portable light device with a hinged door for accessing batteries and a lamp.




Lighting devices are used extensively as flashlights for lighting dark areas, as signaling lamps, for safety, etc.




Heretofore, flashlights have typically included a cylindrical housing with a closed end and an opposite open threaded end. Batteries are inserted into the cylindrical housing and a lamp holder is threaded over the open threaded end of the housing. A switch, usually located on the outer circumference of the housing, can then be activated to alternatively turn the flashlight on and off. The lamp holder typically includes a spring that is biased against the batteries in the housing as the lamp holder is screwed onto the housing. The spring also serves as an electrical contact for powering a lamp in the lamp holder.




Another typical flashlight includes a housing wherein the batteries are side loaded into the housing. In this flashlight, at least one of the electrical contacts is a spring that is stationary relative to the housing. The batteries are inserted into the housing by forcing the contacts apart. The lamp holder for these flashlights are typically threaded onto the body such that the lamp holder can be unscrewed in order to change the lamp in the lamp holder or integral with the body such that the lamp can not be changed.




SUMMARY OF THE INVENTION




One aspect of the present invention is to provide a light device including a battery housing and a door. The battery housing defines an interior space adapted to accept batteries and is adapted to accept a lamp. The door is pivotally connected to the battery housing, with the door having an open position allowing access to the interior space of the battery housing and a closed position for enclosing the interior space of the battery housing. The door includes an electrical cam. The electrical cam is configured to contact batteries in the battery housing when the door is pivoted to the closed position to thereby create a circuit for powering the lamp. The electrical cam is also configured to move away from batteries in the battery housing when the door is pivoted to the open position to thereby allow the batteries to be removed from the interior space of the battery housing.




Another aspect of the present invention is to provide a light device including a housing and a hinged top door, the housing including a cavity configured to retain batteries therein. The housing further includes a lamp holder configured to retain a lamp. The hinged top door is connected to the housing. The hinged top door includes an open position for allowing access to the cavity and a closed position for enclosing the cavity. The hinged top door also includes a cam adapted to hold batteries in the cavity in tight contact with the lamp holder when the hinged top door is in the closed position. The cam is configured to move towards the batteries as the hinged top door is moved to the closed position, thereby applying tension to the batteries to hold the batteries in place to create a circuit for powering the lamp engaged with the lamp holder. The cam is also configured to move away from the batteries as the hinged top door is moved to the open position, thereby releasing the tension holding the batteries in place within the housing and allowing the batteries to be easily loaded and unloaded.




Yet another aspect of the present invention is to provide a light device including a housing, a cover, a reflector, a lamp holder and a door. The housing defines an interior space adapted to accept batteries. The cover is fixed to the housing and allows light to at least partially pass therethrough. The reflector is also fixed to the housing. The lamp holder is adapted to retain a lamp. The lamp holder is removably connected to the housing within the interior space of the housing and is configured to be positioned adjacent the reflector of the lamp enclosure when in the housing to position the lamp between the reflector and the lens. The door has an open position allowing access to the interior space of the housing and a closed position for enclosing the interior space of the housing. The lamp holder is accessible from the interior space of the housing, thereby allowing the lamp to be removed from the housing when the door is in the open position.




In another aspect of the present invention, a light device is provided, wherein the light device includes a housing and a hinged top door. The housing has a first end, a second end and a U-shaped bottom extending between the first end and the second end. The first end, second end and U-shaped bottom define an interior space adapted to accept batteries, the housing including a reflector and a cover at the first end. The housing is configured to accept a lamp between the cover and the reflector. The hinged top door is pivotally connected to the housing and is configured to enclose the batteries within the interior space. The hinged top door includes an open position for allowing access to the cavity and a closed position for enclosing the cavity. The hinged top door also includes a palm surface and the housing includes a grip surface and a trigger detent, with the trigger detent being located between the grip surface and the first end of the housing, thereby ergonomically accepting a hand of a user of the light device with fingers of a user of the light device on the grip surface and a palm of the user enclosed around the palm surface of the hinged top door. The trigger detent is configured to allow a user of the light device to readily actuate the trigger detent with an index finger of the user to thereby alternatively turn the lamp on and off by closing and opening, respectively, a circuit between the lamp and the batteries.




Accordingly, the light devices of the present invention therefore include an ergonomically shaped housing and top door with easy and intuitive lamp and battery access. The light devices are efficient in use, economical to manufacture, capable of a long operable life, and particularly adapted for the proposed use.




These and other features, advantages and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims and appended drawings.

1


. However, it is to be understood that the invention may assume various alternative orientations, except where expressly specified to the contrary. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.




The reference number


10


(

FIGS. 1-6

) generally designates a light device embodying the present invention. In the illustrated example, the light device


10


includes a battery and lamp housing


12


and a hinged top door


14


. Batteries (not shown) and a lamp holder


18


are located within the housing


12


and are accessible by opening the hinged top door


14


. The hinged top door


14


includes a cam


20


at its hinged end holding the batteries in tight contact with the lamp holder


18


when the hinged top door


14


is closed. As the hinged top door


14


is opened, the cam


20


, which holds the batteries in tight contact with the lamp holder


18


, moves away from the batteries, thereby releasing the tension holding the batteries in place within the housing


12


. The batteries can therefore be easily loaded and unloaded. Likewise, as the hinged top door


14


is closed, the tension holding the batteries in place is reapplied to the batteries to create a circuit for powering a lamp


22


(See

FIG. 5

) engaged with the lamp holder


18


. Furthermore, as explained below, the lamp


22


engaged with the lamp holder


18


is also accessed through the hinged top door


14


.




In the illustrated example, the battery and lamp housing


12


(

FIGS. 1-8

) includes an interior cavity


46


, a grip surface


24


, a detent trigger


26


, a lamp enclosure


28


and a pair of struts


52


. As seen in

FIG. 3

, the grip surface


24


is located about the exterior of the housing


12


and is configured to ergonomically accept the fingers of the user of the light device


10


with the palm of the user enclosed around the hinged top door


14


of the light device


10


. The detent trigger


26


is located forward of the grip surface


24


and allows the user of the light device


10


to readily actuate the trigger


26


with the user's index finger to thereby alternatively turn the lamp


22


on and off by closing and opening, respectively, a circuit between the lamp


22


and the batteries. The illustrated struts


52


are parallel and, as explained in more detail below, define an opening


53


therebetween for accepting the hinged top door


14


. The struts


52


extend from and define the back of the internal cavity


46


. As seen in

FIG. 6

, the housing


12


also preferably includes a rear notch


38


having a vertical retaining bar


39


spanning a vertical height of the notch


38


. The retaining bar


39


retains a wrist rope


37


within the notch


38


to thereby connect the wrist rope


37


to the housing


12


.




The illustrated lamp enclosure


28


(

FIG. 5

) of the housing


12


is located at a front end of the housing


12


and includes a bezel


29


encircling a concave reflective surface


31


and a disk-shaped transparent or translucent cover


33


. The concave reflective surface


31


and the cover


33


of the lamp enclosure


28


are similar to the reflective surfaces and covers or lenses of flashlights found in the prior art. Unlike prior art light devices, however, the lamp enclosure


28


is integral with the housing


12


. As seen in

FIGS. 7 and 8

, an interior portion


36


of the lamp enclosure


28


within the interior cavity


46


includes a conical portion


25


and a tubular portion


27


with a central opening


34


for reception of the lamp


22


.




In the illustrated example, the hinged top door


14


(

FIGS. 1-4

,


7


and


8


) includes an enclosure shell


48


for enclosing the interior cavity


46


of the housing


12


and a pivot leg


50


pivotally connected to the housing


12


. The enclosure shell


48


has a substantially inverted U-shaped cross-section and defines an upward facing top palm surface


49


(see FIG.


3


). A user of the light device


10


holds the light device


10


by wrapping his or her palm about the palm surface


49


and gripping the grip surface


24


with his or her fingers and thumb. The wrist rope


37


is adapted to be placed around the wrist of a user of the light device


10


to carry the light device


10


when the grip surface


24


and the palm surface


49


are not grasped by the user of the light device


10


. A lower surface


51


of the enclosure shell


48


accepts the batteries when the hinged top door


16


is in the closed position and includes a plurality of depending flanges


61


having a concave bottom edge


63


for holding the batteries in position. The pivot leg


50


extends from the back of the enclosure shell


48


and is located in opening


53


between the two struts


52


located at the back of the housing


12


. A pivot pin


71


extends through an opening in the pivot leg


50


and into the struts


52


to allow the pivot leg


50


to rotate between the struts


52


. The pivot leg


50


includes the cam


20


. The cam


20


has a first electrical contact strip


54


, which is electrically conductive. The first electrical contact strip


54


is configured to contact one of the batteries and a mating second contact


65


in the housing


12


located between the struts


52


. A circuit is formed between the first electrical contact strip


54


, the mating contact


65


in the housing


12


, a conductor (not shown) running from the mating contact


65


and through the housing


12


that is selectively interrupted by the trigger


26


, to a third electrical contact


55


(see

FIGS. 7 and 8

) positioned adjacent the lamp holder


18


. The circuit is closed when the hinged top door


14


is in the closed position and opened when the hinged top door


14


is in the open position.




The illustrated hinged top door


14


also includes a U-shaped spring actuated locking mechanism


30


(

FIGS. 1

,


2


and


4


). The U-shaped spring actuated locking mechanism


30


has a first leg


41


connected to a first semi-concave portion


40


of the hinged top door


14


at a front end of the hinged top door


14


. A second leg


43


of the U-shaped spring actuated locking mechanism


30


includes a thumb tab


42


and a latch


44


. The latch


44


is configured to engage a bottom surface


45


of top part of the housing


12


behind the lamp enclosure


28


and underneath a second semi-concave portion


57


for maintaining the hinged top door


14


in a closed position (see FIG.


3


). The latch


44


preferably has a bifurcated triangular shape with a downwardly slanted bottom surface


47


that will abut the second semi-concave portion


57


to move the latch


44


rearward as the hinged top door


14


is moved to the closed position, thereby allowing the hinged top door


14


to close. It is contemplated, however, that the second semi-concave portion


57


of the housing


12


could have a downwardly slanted top surface instead of the surface being located on the latch


44


, or that both the hinged top door


14


and the latch


44


could have mating slanted surfaces performing the same function as described directly above. The first semi-concave portion


40


of the hinged top door


14


and the second semi-concave portion


57


of the housing


12


are aligned to form an interrupted concave surface. Once the hinged top door


14


is in the closed position, the resilient material of the U-shaped spring actuated locking mechanism


30


will bias the latch


44


forward, thereby forcing the latch


44


underneath the second semi-concave portion


57


to secure the hinged top door


14


in the closed position. The hinged top door


14


is thereafter opened by pressing rearward on the thumb tab


42


of the U-shaped spring actuated locking mechanism


30


to remove the latch


44


from underneath the bottom surface


45


of the second semi-concave portion


57


, thereby allowing the hinged top door


14


to rotate upwards.




The circuit allowing the lamp


22


to be lit is closed by rotating the hinged top door


14


into the closed position (FIG.


3


), wherein the cam


20


abuts against the adjacent battery and forces the batteries forward into contact with a fourth electrical leaf spring contact


110


of the lamp holder


18


. Therefore, when the hinged top door


14


is in the closed position, the batteries will contact the fourth electrical leaf spring contact


110


on the lamp holder


18


and the first electrical contact strip


54


on the cam


20


of the hinged top door


14


. Additionally, as described in more detail below, the third electrical contact


55


of the housing


12


abuts against a fifth electrical contact


118


of the lamp holder


18


. Therefore, when the hinged top door


14


is in the closed position, an electrical circuit is provided such that the batteries can operate the lamp


22


in the lamp holder


18


in response to actuation of trigger


26


.




The illustrated lamp holder


18


(FIGS.


1


,


2


and


9


-


12


) is manually inserted into and removed from the lamp enclosure


28


through the interior cavity


46


of the housing


12


. The lamp holder


18

100


for connecting the lamp


22


to the body


100


. The cylindrical body


100


of the lamp holder


18


includes the fourth electrical leaf spring contact


110


extending from a rear end of the cylindrical body


100


. The fourth electrical leaf spring contact


110


extends from the rear of the body


100


, through a back wall of the body


100


and into the receptacle


106


in the lamp holder


18


. The fourth electrical leaf spring contact


110


abuts the base contact


112


of the lamp


22


when the base contact


112


of the lamp


22


is inserted into the opening


106


in the body


100


. The fourth electrical leaf spring contact


110


electrically connects the batteries to the base contact


112


of the lamp


22


when the hinged top door


14


is in the closed position. The cylindrical body


100


of the lamp holder


18


also includes the fifth electrical contact


118


extending below the cylindrical body


100


, along a bottom of the body


100


and into the receptacle


106


of the body


100


. The fifth electrical contact


118


also abuts the base contact


112


of the lamp


22


when the base contact


112


of the lamp


22


is inserted into the receptacle


106


of the body


100


. As described in more detail below, the fifth electrical contact


118


electrically connects the third electrical contact


55


of the housing


12


to the base contact


112


of the lamp


22


when the hinged top door


14


is in the closed position.




In the illustrated example, the lamp holder


18


also includes a horseshoe shaped abutment flange


130


extending from a periphery of the body


100


. The abutment flange


130


includes a track


102


located on each side of the cylindrical body


100


. The tracks


102


have a U-shaped cross section and are used to properly insert the lamp holder


18


into the housing


12


of the light device


10


. As seen in

FIGS. 7 and 8

, the housing


12


includes a pair of guides


120


extending from inside walls of the internal cavity


46


of the housing


12


at a position behind the central opening


34


in the interior portion


36


of the lamp enclosure


28


. The pair of guides


120


are preferably located on a plane extending radially from the central opening


34


.




The illustrated lamp holder


18


is connected to the housing


12


of the light device


10


by inserting the lamp holder


18


into the internal cavity


46


of the housing


12


and by inserting the bulb


110


of the lamp


22


and a front portion of the cylindrical body


100


in front of the abutment flange


130


into the central opening


34


in the internal portion


36


of the lamp enclosure


28


until the abutment flange


130


of the lamp holder


18


contacts a rim of the tubular portion


27


of the lamp enclosure


28


. As the bulb


110


of the lamp


22


is being inserted into the central opening


34


in the inter portion


36


of the lamp enclosure


28


, the guides


120


will slide within the tracks


102


of the lamp holder


18


, thereby maintaining the lamp holder


18


in the proper position. It is contemplated, however, that the housing


12


could have the tracks


102


and the lamp holder


18


could include the guides


120


. Once the lamp holder


18


is placed within the housing


12


of the light device


10


, the fifth electrical contact


118


will contact the third electrical contact


55


of the housing


12


. The guides


120


preferably include an off-set flange


122


in the middle of the guides


120


having a semi-circular flange


123


extending from a bottom surface thereof. The semi-circular flanges


123


will snap lock against an end of the tracks


102


of the lamp holder


18


to maintain the lamp holder


18


within the housing


12


when the lamp


22


is fully inserted into the lamp enclosure


28


. The semi-circular flanges


123


will move upward as the lamp


22


is pulled out of the lamp enclosure


28


, thereby allowing the lamp housing


18


to be removed from the housing


12


. The lamp holder


18


also preferably includes a fin shaped gripping flange


104


extending upwardly from a top of the cylindrical body


100


. The gripping flange


104


assists in inserting and removing the lamp holder


18


from the housing


12


.




The light device


10


of the present invention therefore includes an ergonomically shaped housing


12


and top door


14


with easy and intuitive lamp


22


and battery access. As the hinged top door


14


is opened, the spring pressure that holds the batteries in tight contact front to back is released, aiding the ease to which the batteries can be loaded and unloaded. Additionally, as the hinged top door


14


is closed, the spring force is re-applied to the batteries. The lamp


22


is also preferably accessed through the hinged top door


14


. The lamp holder


18


allows a user of the light device


10


to remove the lamp


22


and the lamp holder


18


without having to open the front of the housing


12


or thread off a contact shell.




It will be readily appreciated by those skilled in the art that modifications may be made to the invention without departing from the concepts disclosed herein. For example, it is contemplated that the light device could include the removable lamp holder


18


within the housing


12


, but not include the cam


20


on the top door


14


or a door fixedly connected to the housing


12


. Additionally, it is contemplated that the light device could have the cam


20


on the top door


14


, but not include the removable lamp holder


18


. Such modifications are to be considered as included in the following claims, unless these claims by their language expressly state otherwise.
