Abstract
Abstract A reusable safety warning device. A plurality of reflective strips of flexible material are adapted to protrude outwardly from an end of an elongate cylindrical body member and droop down to form a pompon-like reflector. A battery-powered light source is disposed within the reflector to radiate light which is reflected off of the flexible strips so that the device resembles a burning incendiary flare. Means are provided for retracting the reflective strips and light source inside the elongate body for storage of the device, and the device is provided with a pair of retractable legs for supporting the reflector end of the body above a surface when in use.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
102 words
A reusable safety warning device, comprising an elongate tubular body member, a plurality of thin, streamer-like, flexible shiny strips of glossy reflective material attached to said body member and adapted to protrude longitudinally outward from one end thereof for a first portion of their respective lengths, diverge from one another in a plurality of directions for a second portion of their respective lengths and then droop at their protruding ends under the force of gravity so as to produce a pompon-like array of said strips, and means partially disposed within said body member for retracting said flexible strips into said body member.
Claim 2
Dependent Claim
102 words
A reusable safety warning device, comprising an elongate tubular body member, a plurality of thin, streamer-like, flexible shiny strips of glossy reflective material attached to said body member and adapted to protrude longitudinally outward from one end thereof for a first portion of their respective lengths, diverge from one another in a plurality of directions for a second portion of their respective lengths and then droop at their protruding ends under the force of gravity so as to produce a pompon-like array of said strips, and means partially disposed within said body member for retracting said flexible strips into said body member.
Claim 3
Dependent Claim
64 words
The warning device of claim 1 wherein said retracting means comprises a slidable core disposed within said tubular body member and adapted to be selectively moved within said body member along its longitudinal dimension, said flexible strips being attached to said slidable core so that moving said core away from the end of protrusion of said strips pulls said strips into said tubular body.
Claim 4
Dependent Claim
25 words
The warning device of claim 2 wherein said slidable core includes a light source for producing light to be reflected off of said flexible strips.
Claim 5
Dependent Claim
26 words
The warning device of claim 2 wherein said flexible strips are bound together at one end thereof and attached to an end of said slidable core.
Claim 6
Dependent Claim
51 words
The warning device of claim 1 further comprising light source means adapted to protrude from the same end of said body member as said flexible strips, for producing light to be reflected off of said strips, said strips being attached to the end of said light source means adapted for protrusion.
Claim 7
Dependent Claim
31 words
The warning device of claim 5 wherein said light source means comprises an electric light and said warning device further comprises a portable electric power source disposed within said body member.
Claim 8
Dependent Claim
42 words
The warning device of claim 5 wherein said flexible strips are adapted to droop downwardly around the exterior of said light source means under the force of gravity so that light from said light source means may reflect off of said strips.
Claim 9
Dependent Claim
23 words
The warning device of claim 1 further comprising support means attached to said body member for holding said flexible strips above a surface.
Claim 10
Dependent Claim
30 words
The warning device of claim 8 where said support means comprises a pair of legs retractably attached to the end of said body member from which said flexible strips protrude.
