Abstract
The portable lighting device of the present invention includes a casing defining a battery compartment. The battery compartment may be lined with a shock absorbing material and may be configured to receive a plurality of batteries arranged in at least two rows that are offset with respect to one another. The casing may define two support surfaces with one inclined with respect to the other. A battery cartridge may be used in the lighting device that has a pivoting handle to aid in removal of the cartridge from the battery compartment. A reflector isolator may also be employed to reduce mechanical shock transferred to the lamp. A lantern so constructed can withstand drops of up to 15 feet or more.
Claims46
A portable lighting device comprising:
- a casing including a top, bottom, rear and opposing side surfaces, said casing including an open forward end, said bottom surface providing a first support surface on which the portable lighting device will rest when in a first resting position;
- a reflector mounted within the open forward end of said casing;
- a lens provided across the forward open end;
- a light source disposed between said reflector and said lens;
- and
- a switching mechanism for selectively activating said light source,
- wherein said casing further includes an inclined surface extending between said bottom surface and said rear surface of said casing, said inclined surface providing a second support surface on which the portable lighting device will rest when in a second resting position,
- wherein said first support surface is configured to provide a stable and predictable contact area on which the portable lighting device will rest when in the first resting position and provides a stable first resting position such that the portable lighting device will remain in the first resting position without rolling, and
- wherein said second support surface is configured to provide a stable and predictable contact area on which the portable lighting device will rest when in the second resting position and provides a stable second resting position such that the portable lighting device will remain in the second resting position without rolling.

2 more elements
A portable lighting device comprising:
- a casing defining a battery compartment and having an open end for access to said battery compartment;
- and
- a lens ring assembly releasably attached to the open end of said casing, wherein said lens ring assembly comprises:
- a lens;
- a lens ring for supporting said lens and including connecting means for connecting said lens ring assembly to said casing;
- a light source;
- a reflector having a forward peripheral rim and a rear aperture for receiving said light source;
- and
- a gasket disposed between said forward peripheral rim of said reflector and an inner surface of said lens ring, said gasket being formed of a material capable of absorbing mechanical shocks so as to protect said light source from mechanical shocks delivered to said lens ring and/or casing.
