ABSTRACT:
A shipping rack easily convertible to an extended mode for storing and shipping product, a display mode for displaying product, and a collapsed mode for storing the rack itself. The rack includes a pair of central support columns and a pair of outer posts on either side of the columns. A plurality of shelves are pivotally mounted between the posts and columns. In the extended mode, the shelves are horizontal. As the columns are raised with respect to the posts, the shelves pivot to the desired inclination. Once the shelves are essentially vertical and the posts are drawn close to the central columns, the rack is in the collapsed mode. The rack can be secured in any mode by a strut. A spring counterbalance system installed within one of the central columns assists the mode conversion of the rack.
