Abstract
A kite of delta shape having a frame and sail defining a keel and a pari of wings. Primary and secondary bridle lines are connected together and to the frame and carry connectors, two being located for dual line control and four being located for quad line control whereby the flyer can select either type of control depending on the desired variation he may wish in the maneuvers of the kite while flying.
Claims12
A kite assembly comprising the combination of a frame and a sail of fabric sheet material, said frame and said sail defining a substantially delta shape having a narrow front end and a wide trailing end, a central keel and a pair of wings one each on the opposed sides of said keel, said wings having leading edges defined, respectively, by first and second seams each closed at the narrow end of said delta shape and open at its opposite end, stitching closing said seams to form said leading edges, said frame being defined, in part, by a resilient side strut received in each of the respective seams, each strut having an exposed end extending freely through the open end of a respective seam and beyond the wide end of said delta shape, first and second flexible lines within the respective seams, each line being sewn to said sheet material by a line of stitching extending along at least a portion of the length of said seam whereby said line is anchored to said sheet material along said portion substantially parallel to said seam, one end of each of said lines emerging from a seam at its open end, and means for anchoring said line securely to the exposed end of a side strut following tensioning of said line until said sheet material along a leasing edge is pulled taut along said strut.
A kite comprising a body having front and rear ends and including a frame and a sail supported on said frame to define a central keel extending between the ends of said body and a pair of wings, said frame including a pair of side struts at the leading edges of said wings, a first lateral strut extending across said keel and having its opposite ends connected to said side struts at a first predetermined distance from said front end, a second lateral strut extending across said keel and having its opposite ends connected to said side struts at a second predetermined distance, greater than the first, from said front end, and a bridle for flying said kite alternatively by either dual or quad line control, said bridle comprising a pair of primary bridle lines each having one end connected to a side strut adjacent its connection with an end of said first lateral strut, the opposite end of each primary bridle line being connected to said second lateral strut across said keel and at a predetermined position on said second strut to one side of said keel, a pair of secondary bridle lines, each having one end connected to a side strut adjacent its connection with an end of said second lateral strut and its opposite end connect to a primary line intermediate the ends thereof, a first pair of dual kite control line connectors, each being located at the respective intersections of said secondary and primary bridle lines, and second and third pairs of quad kite control line connectors, one of each second pair of connectors being connected to said primary line intermediate its intersections with said side strut and said secondary bridle line, and one of each third pair of connectors being connected to said secondary line intermediate its connection with a side strut and its connection with said primary line.
