Abstract
Abstract A portable warning device has a heavy base of steel rod formed into a polygon. The rod has a portion, extending into the polygon, to which is pivotally secured a reflector. The portion is spaced from one side of the polygon a distance sufficient to allow the reflector to assume a stored position wherein it lies between the portion and the polygon side substantially within the plane of the base.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
116 words
A portable warning device comprising: a heavy base of metal rod formed in a polygon; said base including a portion of said rod extending into the polygon; a reflector; means to pivotally secure said reflector to said portion; said reflector being pivotal between an operative position wherein it is disposed generally perpendicular to the plane of said base and a stored position wherein it is disposed substantially within the plane of said base; said portion being spaced from one of the sides of the polygon a distance at least as great as the length of said reflector whereby when said reflector is in said stored position it will lie between said portion and said polygon side.
Claim 2
Dependent Claim
116 words
A portable warning device comprising: a heavy base of metal rod formed in a polygon; said base including a portion of said rod extending into the polygon; a reflector; means to pivotally secure said reflector to said portion; said reflector being pivotal between an operative position wherein it is disposed generally perpendicular to the plane of said base and a stored position wherein it is disposed substantially within the plane of said base; said portion being spaced from one of the sides of the polygon a distance at least as great as the length of said reflector whereby when said reflector is in said stored position it will lie between said portion and said polygon side.
Claim 3
Dependent Claim
11 words
The invention of claim 1 wherein said metal rod is steel.
Claim 4
Dependent Claim
70 words
The invention of claim 1 wherein said means to pivotally secure said reflector to said portion comprises a tubular element having a closed end and an open end, said portion extends into said open end, a spring disposed between the end of said portion and said closed end of said tubular element, a C-shaped slot in said tubular element and means secured to said portion and extending through said slot.
Claim 5
Dependent Claim
18 words
The invention of claim 1 further comprising means, carried by said reflector, to secure and support a flag.
Claim 6
Dependent Claim
49 words
The invention of claim 4 wherein said means to secure and support a flag comprises a spring-biased pivotal plate having at least one slot therein and a relatively stationary element extending through said slot and adapted to receive and secure a flagstaff between said element and said pivotal plate.
Claim 7
Dependent Claim
26 words
The invention of claim 5 wherein said pivotal plate extends beyond said stationary element whereby the flag will be wedged between said plate and the flagstaff.
Claim 8
Dependent Claim
27 words
The invention of claim 1 wherein said polygon is a rectangle and said portion is disposed generally parallel to said one of the sides of said polygon.
Claim 9
Dependent Claim
20 words
The invention of claim 1 wherein said portion is elevated slightly above the plane of the remainder of said base.
Claim 10
Dependent Claim
106 words
A portable warning device comprising: a heavy base of metal rod formed in a polygon; said base including a portion of said rod extending into said polygon; clamp means to secure and support a flag or fusee flare including a spring-biased pivotal plate having at least one slot therein and a relatively stationary element extending through said slot and adapted to receive and secure a flagstaff or fusee spike between said element and said pivotal plate; and, means to pivotally secure said clamp means to said portion whereby said clamp means can be pivoted between an operative position and a stored position relative to said base.
Claim 11
Dependent Claim
106 words
A portable warning device comprising: a heavy base of metal rod formed in a polygon; said base including a portion of said rod extending into said polygon; clamp means to secure and support a flag or fusee flare including a spring-biased pivotal plate having at least one slot therein and a relatively stationary element extending through said slot and adapted to receive and secure a flagstaff or fusee spike between said element and said pivotal plate; and, means to pivotally secure said clamp means to said portion whereby said clamp means can be pivoted between an operative position and a stored position relative to said base.
Claim 12
Dependent Claim
26 words
The invention of claim 9 wherein said pivotal plate extends beyond said stationary element whereby the flag will be wedged between said plate and the flagstaff.
