ABSTRACT:
A multi-purpose enclosure is defined by the use of a frame made up of 24 very similar structural members that are carefully notched so that they interlock at the corners to define a joint without the use of any fasteners or adhesive. When properly done, the 24 elongated members which define the joints also define, at each joint, a three-sided inside corner so that there are eight inside corners, one at each joint, which in the preferred embodiment define a cube. Each combination of four inside corners which defines a quadrilateral plane which is orthogonal to one of the three main X, Y, or Z axes of the enclosure seats a panel, in the preferred embodiment, so that a six-sided paneled enclosure is formed for a multitude of uses, a lamp being shown as one example in this disclosure.
