FOLDABLE ELECTRONIC DISPLAY

摘要

A foldable electronic display (10), also known as a variable or changeable message sign, displays important or emergency messages for the control of roadway and highway traffic. The self-contained foldable electronic display (10) is lightweight and portable and can be handled and setup easily and quickly by one person, on a multiplicity of structures. The display (10) may be stowed in the luggage compartment of highway maintenance and emergency response vehicles in a folded orientation when not in use. During use, the display (10) displays a stored or newly created message. A software lockout feature prevents the message from being changed using on-board controls by unauthorized personnel, eliminating the need for mechanical security measures. An optional mounting bracket (22) apparatus assures that the foldable electronic display (10) is held in an open orientation. The mounting bracket (22) apparatus is installed in a manner that is tamperproof and does not allow unauthorized access to mounting hardware (40).
