  • Patent number: 5823100
    Abstract: A baking and/or cooling rack having at least two shelves formed of wire. The shelves are connected by wire support legs such as at the outside corners of the shelves. The connection between each shelf and its attached support legs is provided by a spring pin. The spring pins form hinges which provide a friction force preventing free movement of the connected support legs with respect to the shelves, but which allows forced movement of the connected support legs with respect to the shelves, thereby allowing the rack to fold between an upright position and a knocked down position. A third shelf may be removably supported by the support legs between the first and second shelves.
