Claim 5

A collapsible emergency traffic signal device as set forth in claim 3 wherein said base leg and said side legs are formed of one piece synthetic resin of an orange-red fluorescent color having a dominant wave length in the range of 590 to 610 millimicrons and the reflective members are prismatic with a backing adhered thereto, said backing being next to the respective face of the base leg and side legs.

Claim 6

A collapsible emergency traffic signal device as set forth in claim 4 wherein: a. said support member is a generally flat member adapted to be substantially parallel with a supporting surface; b. said base leg is pivotally mounted on said support member for movement betweeN a position substantially parallel with said support member and a position substantially normal to said support member; and c. said base leg has a support foot depending from adjacent each end portion thereof to cooperate with said support member to maintain the triangular form in the upstanding position.

Claim 7

A collapsible emergency traffic signal device comprising: a. an elongated support member, said support member being a generally flat member adapted to be substantially parallel with a supporting surface, said support member having sufficient weight for stability; b. a planar base leg pivotally mounted on said support member for movement between a position substantially parallel with said support member and a position substantially normal to said support member wherein support member portions extend from the triangular form in opposed relation; c. a pair of planar side legs cooperating with said base leg to form an equilateral triangle, said base leg and said side legs each being elongate substantially flat rigid members positioned in coplanar relation, said side legs having overlapping portions adjacent free ends thereof; d. said base leg and side legs being of synthetic resin and of one piece with hinge means connecting end portions of said base leg and respective adjacent end portions of said side legs with the fold lines bisecting the angle between the base leg and the respective side legs for folding said side legs between the coplanar relation and a position adjacent and substantially parallel with said base leg; e. means releasably engageable with said overlapping portions adjacent the free end portions of said side legs for holding said side legs and said base leg in the triangular form; f. elongate prismatic reflective signal members on at least one face of each of said base leg and said side legs of the equilateral triangular form and extending substantially the length of said base leg and said side legs to form an equilateral triangular of reflective material; and g. brace means extending between said support member and an upper portion of the triangular form for maintaining same in an upstanding position and preventing relative rotation between the triangular form and support member.

Claim 8

A collapsible emergency traffic signal device comprising: a. an elongated support member, said support member being a generally flat member adapted to be substantially parallel with a supporting surface, said support member having sufficient weight for stability; b. a planar base leg pivotally mounted on said support member for movement between a position substantially parallel with said support member and a position substantially normal to said support member wherein support member portions extend from the triangular form in opposed relation; c. a pair of planar side legs cooperating with said base leg to form an equilateral triangle, said base leg and said side legs each being elongate substantially flat rigid members positioned in coplanar relation, said side legs having overlapping portions adjacent free ends thereof; d. said base leg and side legs being of synthetic resin and of one piece with hinge means connecting end portions of said base leg and respective adjacent end portions of said side legs with the fold lines bisecting the angle between the base leg and the respective side legs for folding said side legs between the coplanar relation and a position adjacent and substantially parallel with said base leg; e. means releasably engageable with said overlapping portions adjacent the free end portions of said side legs for holding said side legs and said base leg in the triangular form; f. elongate prismatic reflective signal members on at least one face of each of said base leg and said side legs of the equilateral triangular form and extending substantially the length of said base leg and said side legs to form an equilateral triangular of reflective material; and g. brace means extending between said support member and an upper portion of the triangular form for maintaining same in an upstanding position and preventing relative rotation between the triangular form and support member.

Claim 9

A collapsible emergency traffic signal device as set forth in claim 6 wherein: a. said base leg has a support foot depending from adjacent each end portion thereof and engageable with the supporting surface; b. said base leg and said side legs each have a pair of spaced ribs extending outwardly from opposite faces thereof to define means for holding elongate reflective members on each face of the triangular form; c. said hinge means comprises an integral extension of each of the end portions of said base leg and respective adjacent end portions of said legs joined by a portion of reduced thickness to define a fold line adjacent each end of said base leg; and d. said reflector members are of a width substantially less than a width of the respective base leg and side legs whereby said legs extend inwardly from the reflector members and said hinge means connects the base leg and side legs at said inwardly extending portions.

Claim 10

A collapsible emergency traffic signal device as set forth in claim 7 wherein: a. one of said legs has an offset portion adjacent a free end portion thereof; b. said offset portion is substantially parallel with said one side leg and engageable with a free end portion of the other side leg; c. said offset portion and the free end portion of the other side leg have alignable apertures therein; and d. said means for holding said base leg and said side legs in the triangular form comprises a keeper portion on one end of said brace means and engageable within the apertures in said side legs.
