ABSTRACT:
A kite control mechanism arranged to control a plurality of kite-flying lines. The mechanism includes a pair of spools mounted in a frame by a control shaft having an associated manually operable handle. The kite-flying lines extend outwardly from the spools through elongated slots in the frame and a leverage handle is mounted to the frame for supporting the mechanism during use. The spools may be driven from the mounting shaft by a key thereon selectively engaging keyways in the respective spools so as to permit driving of both spools concurrently or one spool independently of the other when desired. A friction drive device is provided for driving the second spool from the spool being driven by the shaft key so as to permit self-adjusting payout of the kite-flying lines. The second spool may be selectively locked when desired by a manually operable lock device carried on the frame. The selective driving of the spools may be effected by an axial movement of the shaft with the handle further serving to limit the axial movement in one direction. The frame of the mechanism may be flexibly constricted to provide an adjustable friction retarding force between the spools as desired.
