Abstract

Abstract The present invention is a shelving system for storing cans in a pantry so that the labels on the cans are visible. The shelving system includes a plurality of identical variable shelves. Each variable shelf includes a pair of platforms on which the cans are placed and each of which has a bore at one end and a mount on which both platforms are slideably coupled and which has a pair of slots that are aligned with the bores of the platforms. Each variable shelf also includes a pair of supports which are mechanically coupled to the mount by a hinge and are disposed so that the supports intersect each other and a mechanism for adjusting and maintaining the height of the platforms and mount which is determined by the variable point of intersection of the supports. The variable shelves can be placed in serial so that their sides are adjacent to each or in parallel so that the height of each mount is higher the closer it is to the back of the pantry.
