Patent attributes
A stackable rebar chair includes a one-piece body of molded plastic that includes four vertical support legs and four vertical leg receiving sockets. The one-piece body also includes first and second concave rebar cradles that are oriented perpendicular to each other. Each of the support legs has a cross section that defines a first polygon, and each of the leg receiving sockets defines a partial second polygon that is both larger, and differently shaped, that the first polygon. When the rebar chairs are stacked, the four supporting legs of the upper chair are received in the leg receiving sockets of the lower chair in such a manner that a plurality of vertices of the first polygon are positioned, shaped and oriented to simultaneously match respective vertices of the partial second polygon.
