Abstract
Abstract The invention relates to a unique panel joint specifically adapted for quickly assembling or disassembling panels to the configuration of a container, a building structure, or the like. Specifically, a unique flexible hinge arrangement is provided for vertical joints, while a quick-fitting locking arrangement is provided at all base horizontal joints. The base joint comprises a flange on the vertical member mating with a recessed beveled groove on the base member, and a plurality of screws threadably received in the flange of the vertical member having tapered heads slidably received in the beveled groove of the base member whereby when the screws are tightened, they lock into the groove of the base member and secure the vertical member to the base member.
