Abstract
A structure (10, 44, 50) can be formed by using a plurality of hubs (12), connectors (14) and elongate members (16). The hubs (12) have a series of locking slots (18) formed at regular intervals about the outer circumference. A T-shaped portion (32) of a connector (14) is slid into a selected locking slot (18) until a flexible catch (34) on the connector (14) engages a locking bar (20) on the hub (12) to securely attach the connector (14) to the hub (12). Both the hubs (12) and connectors (14) can frictionally receive elongate members (16), allowing the construction of various types of structure, such as furniture. The structures can be assembled without tools, and can be readily be disassembled if desired.
