Abstract: A canopy support structure includes a support pole having a track, a three-dimensional array of hub pairs, and a plurality of articulating arms connecting the hub pairs. The track extends in a longitudinal direction along the support pole. The hubs of each hub pair are movable toward/away from each other during extension/retraction of the canopy support structure. A primary hub pair includes a first hub and a second hub, with each of the first hub and the second hub coupled to the support pole. At least one of the first hub and the second hub is slidably engaged with the track and movable along the support pole. The articulating arms include sets of scissor-connected primary articulating arms. Each of the hub pairs is pivotally connected to at least one other of the hub pairs by a respective set of the scissor-connected primary articulating arms.

Abstract: A canopy support structure includes first and second hubs coupled to and movable along the pole or first and second hubs of which one is coupled to and movable along a track. The first and second hubs are movable toward each other during extension of the canopy support structure and away from each other during retraction of the canopy support structure. A plurality of articulating arms is connected directly or indirectly to the first and second hubs. The articulating arms include sets of scissor-connected primary articulating arms. At least some of the sets of scissor-connected primary articulating arms are connected directly to the first and second hubs and extend outward from the first and secondary hubs during expansion of the canopy support structure.
