Abstract:
1. An edge warning device comprising: a first non-rigid sheet defining a top surface and a bottom surface disposed opposite said top surface, one end of said first sheet defining a first sleeve extending in an axial direction; a second non-rigid sheet, one end of said second sheet defining a second sleeve extending in an axial direction; a first bolster including a first bolster cover and a first filler member extending in an axial direction and inserted into said first bolster cover, said first bolster received in said first sleeve of said first sheet; a second bolster including a second bolster cover and a second filler member extending in an axial direction and inserted into said second bolster cover, said second bolster received in said second sleeve of said second sheet; at least a first elongated mechanical fastener strip attached on the bottom surface of said first sheet in a manner arranged to extend in a direction that has at least one directional component that is parallel to the axial direction in which the first sleeve extends; and at least a second elongated mechanical fastener strip attached on the top surface of said second sheet in a manner arranged to extend in a direction that has at least one directional component that is perpendicular to the axial direction in which the second sleeve extends; and wherein the distance between the first sleeve and the second sleeve is selectively variable from zero to substantially the sum of the distances of the free edge of each sheet to the sleeve of the respective sheet by overlying a selective region of the first elongated mechanical fastener strip with the second elongated mechanical fastener strip so as to selectively detachably join the first sheet to the second sheet with a predetermined distance between the first sleeve and the second sleeve.
