ABSTRACT:
A jack stand and a method for manufacturing a jack stand of the type used in supporting a vehicle. A rectangular sheet metal plate is stamped so as to form at least two elongated parallel slots in the sheet metal plate, the elongated parallel slots being spaced apart from one another and each being spaced from the lateral sides of the sheet metal plate. The slots define three parallel planar legs integrally joined to a transverse body portion of the rectangular sheet metal plate. The rectangular sheet metal plate is bent such that the transverse body portion of the rectangular sheet metal plate forms a cylindrical body. The legs are each bent about a longitudinal axis and the free ends of the legs are bent radially outwardly away from one another so as to define a tetrahedral structure supporting the cylindrical body.
