Abstract:
A hub for a pop-up display structure having a plurality of pivoting tubes, the hub comprising:a first hub member having a plurality of first openings sized to receive the plurality of pivoting tubes, the first hub member having a projection extending therefrom and having a threaded second opening disposed therein; a second hub member having a plurality of first openings sized to receive the plurality of pivoting tubes, the second hub member having a second opening defined therein and having a third opening sized to receive the projection on the first hub member such that the first and second hub members are thereby placed in registry; a fastener removably attaching the first hub member to the second hub member such that the first hub member and the second hub member are aligned so that the plurality of first openings on the first hub member align with the plurality of first openings on the second hub member, the fastener capable of extending through the second opening in the second hub member into the second opening in the first hub member to attach the first and second hub members together when the first and second hub members are in registry and capable of operating such that the first hub member and the second hub member can be separated a distance sufficient to allow removal of at least one of the pivoting tubes without disengaging the fastener from the first and second hub members; and, each first opening in at least one of the first and second hub members being bordered on at least one side by a seat portion sized to receive a structure on each pivoting tube such that the pivoting tubes are capable of rotating about an axis defined by the structure.
