Abstract
A collapsible highway sign assembly includes a cross brace assembly having first and second semi-flexible arms pivoted together for pivoting between storage and display positions. Each arm has first and second ends with four fastener stops, each being adjacent one arm end. A sign sheet of a flexible material with opposing message-bearing and attachment faces has four fasteners secured to the attachment face so each slidably receives an arm end and engages the fastener stop adjacent the arm end when the cross brace assembly is in the display position. A pair of flags are pivoted to a first arm upper end with a friction fit. For storage, a flag storage cavity is pivoted between the first and second arms. An anti-kiting device is secured to the sign sheet attachment face and surrounds an arm to resist kiting and maintain the sign assembly in a safe position visible to oncoming motorists. Methods of deploying and preparing the sign assembly for storage are provided.
