Articulating sign cover clamp

Abstract

A portable clamping device that improves the Prior Art of safely securing materials covering the face of a mounted sign to hide advertised information. It relates primarily to traffic control operations in the Transportation Engineering industry, especially during road construction and maintenance operations. It includes two expandable hooks that straddle the edge of a sign, and one flat bar placed over the material on the front surface, such that when the hooks are clamped to the rear surface of the sign, the bar reacts by gripping the front. Hooks can swivel and slide along the full length of the bar, which allows the device to articulate around the corners and edges of planar signs of any shape. Hook operations may be manual or electronic. The device is safe and easy to use, non-destructive to signs, resistant to the elements, and cost effective.
