Emergency sign device

A device capable of being mounted on a horizontal surface of a motor vehicle for exhibiting emergency signs, comprising first, second and third plate sections of equal size, first hinge means interconnecting one side edge of said second plate section with one side edge of said first plate section, second hinge means interconnecting the other side edge of said second plate section with one side edge of said third plate section, flanges extending outwardly from the other side edges of said first and said third plate sections and being rigidly connected thereto, said flanges forming an angle greater than 90.degree. with the outer surfaces of said first and said third plate sections, detachable fasteners provided on said flanges for detachably securing said first and third plate sections together in an assembled triangular-shaped support in which said flanges are in face-to-face contact with one another, means on one of said plate sections for detachably mounting said support to the horizontal motor vehicle surface, at least one pair of spaced, parallel channel-forming elements on another of said plate sections extending parallel to said side edges and opening toward one another for the reception of interchangeable emergency signs, and fastener means on said one plate section and on the remaining one of said plate sections for securing all of said plate sections together in a collapsed condition lying substantially parallel to one another, said fastener means including straps extending outwardly of opposite end edges of said one and said remaining plate sections and overlapping with opposite end edges of said another plate section in the collapsed condition of said support, said straps being located on said one and said remaining plate sections so as to lie between said channel-forming elements when overlapping said another plate section, whereby the emergency signs are completely prevented from moving outwardly of said elements while in said collapsed condition.
