Abstract: A gazebo and a lean-to shelter have rigid panels with a soft material canopy spread over an arrangement of spokes or ribs. The gazebo has a compression spoke arrangement for holding the canopy in a dome configuration. The spokes of the gazebo include a flat hook underneath each spoke adapted to engage a draw cable at the top periphery of the rigid panels, and a sleeve fits over the end of the spoke and the end of the flat hook to lock the draw cable within the hook. A tip engages the end of the tube and the sleeve to lock it in position on the flat hook. The ribs of the lean-to have a toggle arrangement for extending the ribs when the lean-to shelter has been assembled and to apply tension on the canopy. The end of the toggle is adapted to fit in a rail which in turn also receives the edge of the canopy, and the rail is mounted in a track.
