ABSTRACT:
A multi-purpose frame structure has basic frame members consisting on the one hand of an octagonal tube and on the other hand of a connector. The octagonal tube is provided on its outer sides with dovetail slots and on its inside with opposed longitudinal engaging surfaces. The connector is in the form of a support with orthogonally disposed legs that can be received in the octagonal tube, each leg having a series of transverse projections which engage the surface projections inside of the tube. A frame may be made up from a number of the tubes and connectors and numerous other fittings may be provided which fit in the dovetail slots.
