发明名称 Threshold protective cover with hinge
摘要 A hinged protective cover for protecting a door threshold during construction or modification of a building or its contents. The cover is attached to a horizontal surface such as a building floor and covers the door threshold to prevent damage from foot traffic, contaminants and grit materials which may become lodged in the threshold. The hinge allows positioning of the protective cover to permit door closure while remaining attached to the floor. This leaves the cover in place for repositioning to the protecting position when the door is reopened and serves as an affirmative reminder to accomplish same.
