Abstract: A corner protector comprises two sheets of superposed material joined along two straight edges that meet at an angle of 135°. It is open along any other edge. The sheets are swingable relative to each other about the joined edges, whereby when the sheets are swung about the joined edges until the two edges are at a right angle to each other, a corner protector is produced which has three flat sides each of which meets the other two sides at a right angle.

Abstract: A corner protector comprising a pair of layers of padding material superposed on each other and open along one edge and closed along three other edges by securement of the layers of padding material against each other. The three closed edges comprise a central edge joined at each of its ends to a closed edge at an obtuse angle of 135.degree.. The three closed edges are straight, and the central edge is substantially shorter than the other two closed edges and parallel to the open edge. Each closed edge other than the central edge meets the open edge at an angle of 45.degree.. To protect a corner of an object, the corner protector is bent until the two closed edges other than the central edge are disposed parallel to each other and spaced apart a distance equal to the length of the central edge, thereby to form a pocket, and the corner to be protected is inserted into this pocket.
