Structural system connection

An interlocking structural system comprising:

• a plurality of tubular strut members defining a central opening in the ends thereof of a prescribed diameter;
• and,
• at least one connector for selectively interconnecting said plurality of tubular strut members, said connector including a plurality of removably interconnected plate members, one of said plate members lying generally in a first plane;
• at least a second of said plate members lying generally in a second plane intersecting said first plane so that said plate members intersect along a first common line and at least a third of said plate members lying generally in a third plane transversely intersecting said first and second planes at a point of intersection intermediate the ends of said first common line, intersecting said first plane along a second common line and intersecting said second plane along a third common line;
• each of said plate members defining a plurality of connector tangs thereon generally radially oriented with respect to said plate member, one of said connector tangs on said one of said plate members intersecting one of said connector tangs on said another of said plate members along one of said common lines, said connector tangs sized to be received in said central opening in the end of one of said strut members so that said strut member can be slipped over said intersecting connector tangs to connect said strut member to said connector and to hold said plate members together whereby said connector, when assembled, supports said tubular struts simultaneously with said tubular struts holding said connector assembled.
