Abstract
In a fabric enclosure such as a tent wall there is provided an opening in the fabric panel with a fabric closure panel for closing the opening having a hinge line along one side connecting the closure panel to the wall panel. The opening and the closure panel each define an edge thereof opposite to the hinge line which is curved from an end at the hinge line around to an opposite end separated from the hinge line by a non-flexible rod with the edge of the closure panel overlapping the edge of the opening for closure thereon and a flexible bowing strip attached to the edge of the closure panel which is forced into a bowed shape to apply tension to the closure panel tending to maintain the panel flat.
Claims18
A fabric structure comprising:
- a fabric wall panel of the fabric structure defining a plane of the panel and defining side edges of the wall panel and a bottom of the wall panel for resting along a ground surface;
- an opening in the fabric wall panel;
- a fabric closure panel for closing the opening having a hinge line along one side connecting the closure panel to the wall panel;
- wherein the fabric wall panel at the opening and the fabric closure panel each define an edge thereof opposite to the hinge line with the edge of the fabric closure panel overlapping the edge of the fabric wall panel at the opening for closure thereon;
- wherein the edge is curved;
- a flexible bowing strip attached to the edge of the fabric closure panel opposite to the hinge line, which bowing strip is forced into a bowed shape from an initial different shape such that the flexible bowing strip tends to return to the initial shape generating forces in the bowing strip biasing ends of the bowing strip apart;
- and wherein the flexible bowing strip is attached to the edge of the closure panel such that the forces in the bowing strip biasing the ends of the bowing strip apart act to apply tension to the closure panel tending to maintain the panel flat.
