Abstract
One preferred embodiment of an improved concrete anchor designed in accordance with the present invention for embedment in a concrete panel or the like includes an elongated bar having substantially flat parallel faces, an inner end disposed within the panel, an outer end disposed within a recess in the surface of the concrete panel and side edges extending between the faces. The side edges extend in continuously diverging relationship from adjacent the outer end to adjacent the inner end. In accordance with another embodiment, the preferred concrete anchor includes an elongated bar having substantially flat parallel faces; an inner end disposed within the panel; an outer end disposed within a recess in the surface of the concrete panel; and side edges, preferably substantially straight, which extend in a substantially parallel relationship between the faces. The outer end includes spaced, outwardly-projecting extensions disposed adjacent the side edges of the bar and, preferably, an elongated opening. The inner end is complementary in shape to the outer end, except that a major portion of the inner end is occupied by a void, preferably of triangular shape. The preferred concrete anchor is susceptible of relatively simple and economic manufacture as a unitary stamping.
