A hub assembly for a tent has open, intermediate, and closed configurations, with pairs of fasteners and pins having a first distance in a first direction substantially equal to a second distance between fasteners and the pins along a second direction different from the first direction. When the first and second distances are equal, a biasing member is in a first state in both the open and closed configurations. In the intermediate configuration between the open and closed configurations, the biasing member has a second state which is compressed, and a vertical distance between pairs of fasteners and pins is greater than the first distance. Moving the poles from the intermediate configuration to either the open or the closed configurations decreases the vertical distance between the fastener and the pin which transitions the biasing member from the second state to the less compressed first state. |

1. A hub assembly for a tent having a plurality of poles, the hub assembly comprising:
a hub having a central member in a central aperture and a plurality of arms, each arm having a fastener aperture for receiving a fastener which pivotably connects a first hole of a respective pole to the arm; a base having a shaft and a plurality of walls, with the central member slidably disposed in the shaft, with pairs of the walls forming pole slots each for receiving a respective pole, each wall having an elongated guide slot for receiving a pin which passes through a second hole of a respective pole in the pole slot; a biasing member disposed in the shaft; wherein, with the poles in an open configuration, the pins are in a locking position in the elongated slot; wherein, when the poles are moved to a closed configuration, the pins are moved from the locking position to an unlocked position in the elongated slot; and wherein, for each pole, a first distance between the respective fastener and the respective pin along a first direction is substantially equal to a second distance between the fastener and the pin along a second direction different from the first direction. |
