Hub structures inter-connectable with and/or connected to elongated frame members (e.g., rod-type members) to form frames. In certain non-limiting, example, embodiments, hubs which have simple configurations and/or which are connectable to elongated frame members (e.g., rod-type members) employing small numbers of connectors (e.g., one screw-type connector per frame member/hub connection) and/or which are more easily assembled/disassembled to frame members for constructing and/or deconstructing frame structures. |
