Abstract: A method of placing a shelf in a storage compartment, consisting of the following described steps. Firstly, select a pair of shelf members having opposed ends. The distance between the opposed ends is substantially equal to the distance between interior sidewalls of the storage compartment. Secondly, select a pair of support members having opposed ends. The distance between the opposed ends corresponds to a desired shelf height. Thirdly, pivotally connect adjacent opposed ends of the shelf members and the support members to form a parallelogram frame. Fourthly, collapse the parallelogram frame to permit insertion into the storage compartment. Fifthly, bring the support members into engagement with the interior sidewalls of the storage compartment thereby orienting the shelf members perpendicular to the support members, with the interior sidewalls of the storage compartment providing lateral support.
