Adjustable area kite or wing

Abstract

A kite includes a frame including a leading edge support and a plurality of struts extending rearward from the leading edge support, a flexible main canopy attached to the frame and at least one flexible kite sizing section adjustably attached to the flexible main canopy. The at least one flexible kite sizing section is adjustable to change an area of the kite, including an area of at least a first wing tip section of the kite.

What is claimed is: 
     
         1 . A kite, comprising:
 a frame comprising a leading edge support and a plurality of struts extending rearward from the leading edge support;   a flexible main canopy attached to the frame; and   at least one flexible kite sizing section adjustably attached to the flexible main canopy, wherein the at least one flexible kite sizing section is adjustable to change an area of the kite, including an area of at least a first wing tip section of the kite.   
     
     
         2 . The kite of  claim 1  wherein the at least one flexible kite sizing section is foldably or removably attached to the flexible main canopy. 
     
     
         3 . The kite of  claim 1  wherein the at least one flexible kite sizing section is removably attached to the flexible main canopy. 
     
     
         4 . The kite of  claim 3  comprising a first flexible kite sizing section removably attachable to the main canopy at the first wing tip section of the kite and a second flexible kite sizing section removably attachable to a second wing tip section of the kite. 
     
     
         5 . The kite of  claim 1  wherein the leading edge support is generally arced in shape over at least a portion thereof. 
     
     
         6 . The kite of  claim 3  wherein the at least one flexible kite sizing section is removably attachable to a trailing edge of the main canopy via at least one releasable fastener. 
     
     
         7 . The kite of  claim 6  wherein the at least one releasable fastener comprises at least one section of hook-and-loop type fastener. 
     
     
         8 . The kite of  claim 6  wherein the at least one flexible kite sizing section extends from the first wing tip section to a second wing tip section of the kite. 
     
     
         9 . The kite of  claim 7  wherein the at least one releasable fastener comprises at least one section of hook-and-loop type fastener extending along at least a portion of the trailing edge of the main canopy and the at least one flexible kite sizing section comprises a cooperating hook-and-loop type fastener extending along at least a portion of a forward edge thereof. 
     
     
         10 . The kite of  claim 2  wherein the at least one of the plurality of struts is adjustable in length. 
     
     
         11 . The kite of  claim 2  wherein the leading edge support is adjustable in at least one of length or conformation. 
     
     
         12 . The kite of  claim 7  wherein the leading edge support and the plurality of struts are inflatable. 
     
     
         13 . The kite of  claim 12  wherein at least one of the plurality of struts is adjustable in length and the kite comprises at least one retainer to maintain the at least one of the plurality of struts in an adjusted length. 
     
     
         14 . The kite of  claim 7  further comprising a first wing tip member extending from a first end of the leading edge support and a second wing tip member extending from a second end the leading edge support, the first wing tip member and the second wing tip member being dimensioned to affect control of the kite upon removal of the at least one kite sizing section. 
     
     
         15 . The kite of  claim 1  wherein at least one of the main canopy and the at least one kite sizing section includes at least one port therein which can be opened or closed by a user of the kite. 
     
     
         16 . The kite of  claim 15  wherein the at least one port can be opened to varying sizes. 
     
     
         17 . A method of altering the flight characteristics of a flexible wing comprising:
 providing a flexible main canopy of the wing; and   providing at least one flexible kite sizing section adjustably attached to the main canopy, wherein the at least one flexible kite sizing section is adjustable to change an area of the kite, including an area of at least a first wing tip section of the kite.
