Selectively frictionally engaged hole cover
A selectively frictionally engaged hole cover for a bore hole cored from a paved surface that includes a cover plate configured to cover the bore hole and support vehicular traffic. An engagement mechanism is attached to the cover plate and extends down into the bore hole. The engagement mechanism is configured to be actuated by a user torque input that causes an engagement plate selectively shiftable relative to the cover plate to thereby shift an engagement member along a sloped wall and thus radially outwardly or inwardly, causing the engagement mechanism to selectively engage or disengage the wall of the bore hole. When the engagement member is in frictional contact with the hole, unintentional extraction of the engagement mechanism is prevented. The selectively frictionally engaged hole cover effectively provides a temporary cover for a bore hole in a road, parking lot, or other paved surface.
