Patent attributes
A modified A-frame tent or tarp shelter in which the fly or outer canopy is supported by two upright poles spaced apart on either side of a rectangular footprint. The poles are oppositely offset from the midpoint of the footprint on their respective sides, such that the canopy ridgeline between the poles crosses the footprint diagonally. Two corners of the canopy corresponding to corners of the footprint farthest from their respective (same-side) poles are raised and tensioned by short struts that, in cooperation with the offset poles, create a sidewall effect across the ends of the canopy over the head and foot ends of the footprint. The canopy may further include vestibule portions extending to the sides of the footprint, and the struts may also engage the vestibule portions at their respective corners.
