Abstract
An expandable locker shelf is disclosed that can be placed between two substantially vertical members, such as in a locker. The expandable shelf includes a first section having a rack, a second section, and a lever arm having a pinion. The first and second sections are aligned to engage the pinion with the rack. The lever arm enables the user to provide sufficient torque on the pinion to bias the first and second sections between the two substantially vertical members. The expandable locker shelf is locked between the two substantially vertical walls by engaging the lever arm with a retaining post.
