Abstract
The present invention relates to a sign that can be folded. The folding sign includes a flexible cover having at least one surface for displaying information, such as hazard symbols or words. The flexible cover is supported by a supporting device that is configured to move between a closed or folded position to an open position. The support device also enables the folding sign to move to a collapsed position. The folding sign additionally includes connecting mechanisms that enable the flexible cover to release as the folding sign moves into the collapsed position.
