Abstract
Abstract A hinge assembly which allows pivotal movement between first and second panels of 90° and which allows separation of the two panels. The hinge assembly comprises a first portion located on the first panel and having a lip extending substantially perpendicularly therefrom, a second portion located on the second panel, and a hinge member rigidly coupled to the second panel and having an arm defining a slot with the second portion, which slot receives the lip therein when the first and second panels are substantially perpendicular and receives the first portion therein when the first and second panels are substantially parallel.
