发明名称 Construction apparatus
摘要 A construction apparatus has a plurality of relatively flat components having at least three sides, an elongated rod-like member extending along each side and enlarged corner portions between the members. A plurality of connectors is provided for connecting together adjacent sides of adjacent members to form structures. Each connector has a pair of recesses shaped to releasably embrace adjacent pairs of members. The recesses of each connector open outwardly in a common direction so connectors may be positioned on pairs of members without altering previously formed portions of the structure.
