<p>A TENT WITH ARCHED BOWS A tent is formed of a plurality of like bows struck on an arc of predetermined radius which may be eight feet more or less in radius. The ends of the bows have a pivot means thereon by which the bows are pivoted to opposite plates so that the bottom bows can swing upwardly against the central vertical bow or a pair of central vertical bows may swing from vertical to horizontal positions. Oval sections of fabric are joined together to fill the areas between the bows, stitched or otherwise secured together and to a listing strip at each edge through each of which a bow is threaded. When a pair of vertical bows are used, the fabric terminates around each bow so they can move away from each other. A cord or line can be pulled to raise one or the other of the horizontal bows or gear means, manually or motor driven to operate the vertical bows or the vertical or horizontal bows selectively. The cord or gears can be used on the inside or outside of the tent to raise or lower the bows.</p> |
