US Patent 7219680 Backpack hunting blind

A backpackable, collapsible blind designed to be mounted against a tree for use by hunters and others. The blind has a backpack-capable frame with canopy support arms that are collapsible against the frame for use as a backpack, a removable canopy, and a seat on a lower part of the frame that can be used to support a backpack load. The support arms define a unique upper/lower support structure for the canopy relative to the seat, with the canopy having a generally triangular opening located above the seat and a lower end or hem that hangs below the seat and the lower end of the frame for a baseless, open-bottomed blind that is useful for nearly any hunting situation.
