Abstract

Abstract An improved portable light fixture is disclosed which is specifically adapted to be hand-held and utilized for emergency applications, particularly with respect to motor vehicles. The fixture comprises a conical-shaped lens which is rotatably mounted to a cylindrical housing. Disposed within the interior of the housing is a spool which is rigidly attached on one end of the lens and on the other end to a plate disposed on the bottom of the housing, such that the lens, spool, and bottom plate will rotate in unison. The spool further includes a winding of electrical wire, one end of which is connected to a conventional light bulb disposed beneath the lens and the opposite of which includes a connector which may be inserted into a cigarette lighter of an automobile, or alternatively connected by way of alligator clips to the main terminal of an automobile.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 201 words
A portable light fixture comprising: a generally cylindrical housing comprising an upper tubular portion having first and second ends, said first end including an inwardly-turned lip having an interior surface wherein said lip defines a generally circular opening therein and said second end including a bottom plate attached thereto; a spool disposed within said housing; a light mounted to said spool; a length of conducting material windable about said spool having first and second ends, said first end being electrically connected to said light, said second end having means for electrically connecting said conducting material to a power source external of said housing; and a conically-shaped lens having an open end, said open end including an outwardly extending flange defining upper and lower surfaces disposed about the periphery thereof, said lens being sized and configured to be grasped in the hand of a user and be manually rotated to impart corresponding rotational movement of said spool to pay in and pay out said conducting material from said housing, said lens being disposed within said generally circular opening such that said upper surface of said flange abuts said interior surface of said lip thereby forming bearing surfaces during rotation of said lens.
Claim 2
Dependent Claim 201 words
A portable light fixture comprising: a generally cylindrical housing comprising an upper tubular portion having first and second ends, said first end including an inwardly-turned lip having an interior surface wherein said lip defines a generally circular opening therein and said second end including a bottom plate attached thereto; a spool disposed within said housing; a light mounted to said spool; a length of conducting material windable about said spool having first and second ends, said first end being electrically connected to said light, said second end having means for electrically connecting said conducting material to a power source external of said housing; and a conically-shaped lens having an open end, said open end including an outwardly extending flange defining upper and lower surfaces disposed about the periphery thereof, said lens being sized and configured to be grasped in the hand of a user and be manually rotated to impart corresponding rotational movement of said spool to pay in and pay out said conducting material from said housing, said lens being disposed within said generally circular opening such that said upper surface of said flange abuts said interior surface of said lip thereby forming bearing surfaces during rotation of said lens.
Claim 3
Dependent Claim 65 words
A portable light fixture, as defined in claim 1, wherein said spool is comprised of an annular member having a top end and a bottom end, said bottom end terminating in an outwardly extending rim and said top end having a generally circular surface associated therewith, said conducting material being disposed about said annular member and maintained thereon by said rim and said circular surface.
Claim 4
Dependent Claim 22 words
A portable light fixture as defined in claim 2, wherein said lower surface of said flange is secured to said circular surface.
Claim 5
Dependent Claim 200 words
A portable light fixture comprising: a generally cylindrical housing comprising an upper tubular portion having first and second ends, said first end including an inwardly-turned lip having an interior surface wherein said lip defines a generally circular opening therein and said second end including a bottom plate attached thereto; a spool disposed within said housing; a light mounted to said spool; a length of conducting material windably about said spool having first and second ends, said first end being electrically connected to said light, said second end having means for electrically connecting said conducting material to a power source external of said housing; and a lens having an open end, said open end including an outwardly extending flange defining upper and lower surfaces disposed about the periphery thereof, said lens being sized and configured to be grasped in the hand of a user and be manually rotated to impart corresponding rotational movement of said spool to pay in and pay out said conducting material from said housing, said lens being disposed within said generally circular opening such that said upper surface of said flange abuts said interior surface of said lip thereby forming bearing surfaces during rotation of said lens.
Claim 6
Dependent Claim 200 words
A portable light fixture comprising: a generally cylindrical housing comprising an upper tubular portion having first and second ends, said first end including an inwardly-turned lip having an interior surface wherein said lip defines a generally circular opening therein and said second end including a bottom plate attached thereto; a spool disposed within said housing; a light mounted to said spool; a length of conducting material windably about said spool having first and second ends, said first end being electrically connected to said light, said second end having means for electrically connecting said conducting material to a power source external of said housing; and a lens having an open end, said open end including an outwardly extending flange defining upper and lower surfaces disposed about the periphery thereof, said lens being sized and configured to be grasped in the hand of a user and be manually rotated to impart corresponding rotational movement of said spool to pay in and pay out said conducting material from said housing, said lens being disposed within said generally circular opening such that said upper surface of said flange abuts said interior surface of said lip thereby forming bearing surfaces during rotation of said lens.
