Abstract
Abstract A fluorescent lantern generally comprising a single piece chassis and a cover which removably fits over the rear portion of the chassis. The chassis has a unitary reflector section with a pair of integral sockets for supporting the electrical contacts of a fluorescent lamp. A compartment section for housing the battery and switching mechanism is integrally disposed on the back of the reflector section. When properly mounted in the compartment section, the batteries are electrically connected to the fluorescent lamp through the switching mechanism and the reflector sockets. The switching mechanism is also used to selectively make and break the electrical circuit from the battery to the lamp.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
260 words
A fluorescent lantern comprising a single piece chassis, said chassis having a unitary reflector section and a compartment section integral with said reflector section, battery means disposed in said compartment section, a fluorescent lamp supported by said reflector section so as to direct its light outwardly from said chassis, and means for electrically connecting said fluorescent lamp to said battery means, wherein said unitary reflector section is comprised of a concave rectangular reflector, said concave reflector defining a lens opening, a sealing rim integral with said concave reflector being peripherally disposed around said lens opening, said concave reflector also having a pair of integral sockets located at opposite ends of said concave reflector, said sockets being aligned on the apex of said concave reflector facing said lens opening, and wherein said compartment section is rectangular and longitudinally aligned with said reflector section, said compartment section being integral with said concave reflector opposite said sockets and said lens opening, and wherein said compartment section is comprised of a pair of sidewalls connected together at each end by a pair of integral end portions, each of said sidewalls also having an integral perpendicular divider wall extending almost to the opposite sidewall, each of said divider walls being disposed equidistant to but on opposite sides of the midpoint of said compartment section, said divider walls thereby defining with a portion of said sidewalls a switching mechanism compartment between themselves, and each divider wall also defining a battery compartment with a portion of said sidewalls and said end portion closest to said divider wall.
Claim 2
Dependent Claim
260 words
A fluorescent lantern comprising a single piece chassis, said chassis having a unitary reflector section and a compartment section integral with said reflector section, battery means disposed in said compartment section, a fluorescent lamp supported by said reflector section so as to direct its light outwardly from said chassis, and means for electrically connecting said fluorescent lamp to said battery means, wherein said unitary reflector section is comprised of a concave rectangular reflector, said concave reflector defining a lens opening, a sealing rim integral with said concave reflector being peripherally disposed around said lens opening, said concave reflector also having a pair of integral sockets located at opposite ends of said concave reflector, said sockets being aligned on the apex of said concave reflector facing said lens opening, and wherein said compartment section is rectangular and longitudinally aligned with said reflector section, said compartment section being integral with said concave reflector opposite said sockets and said lens opening, and wherein said compartment section is comprised of a pair of sidewalls connected together at each end by a pair of integral end portions, each of said sidewalls also having an integral perpendicular divider wall extending almost to the opposite sidewall, each of said divider walls being disposed equidistant to but on opposite sides of the midpoint of said compartment section, said divider walls thereby defining with a portion of said sidewalls a switching mechanism compartment between themselves, and each divider wall also defining a battery compartment with a portion of said sidewalls and said end portion closest to said divider wall.
Claim 3
Dependent Claim
91 words
A fluorescent lantern as defined in claim 1 wherein said battery means comprises a pair of batteries, said batteries having a peripherally disposed terminal and a centrally disposed terminal both of which are located on the front surface of said battery, each of said batteries being removably disposed in one of said battery compartments so that each of said battery terminals contacts a metal contact strip mounted on said divider walls, said metal strips being separated from each other by a series of separators and ridges integral with said divider walls.
Claim 4
Dependent Claim
69 words
A fluorescent lantern as defined in claim 2 wherein a standard switching mechanism is disposed in said switching mechanism compartment, said switching mechanism being electrically connected to said metal contact strips and combining said batteries in series when said batteries are in place in said battery compartments, said switching mechanism also having a pair of output terminals of opposite polarity which are internally connected to said series combined batteries.
Claim 5
Dependent Claim
57 words
A fluorescent lantern as defined in claim 3 wherein said fluorescent lamp is comprised of a gas filled cylindrical tube having an electrical contact at each end, said lamp being fired thereby becoming illuminated when each of said contacts is connected to one of said output terminals of said switching mechanism when said batteries are in place.
Claim 6
Dependent Claim
64 words
A fluorescent lantern as defined in claim 4 wherein said contacts of said fluorescent lamp rest in and are supported by said sockets, each of said sockets having a resilient conductive clip mounted therein, each of said clips being electrically connected to one of said output terminals of said switching mechanism and contacting said contacts of said lamp when said lamp is in place.
Claim 7
Dependent Claim
30 words
A fluorescent lantern as defined in claim 5 wherein said switching mechanism provides a means to selectively break the electrical circuit from said batteries to said clips in said sockets.
Claim 8
Dependent Claim
44 words
A fluorescent lantern as defined in claim 6 wherein said chassis has a removable cover, said cover being configured to fit over the rear portion of said chassis so that a front edge of said cover fits into said sealing rim of said chassis.
