Kite and selling method of kite

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher (upstream) than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the portions of the kite sheet corresponding to the intersection of the spine and slant beams and those of the main beams are pasted in advance with strong tapes reinforced with filler or glass fiber.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher (upstream) than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the spine, the longitudinal beams, secondary beams and the outermost leading edges are pasted in advance, and the main beams with spring holders and the slender plates of foamed resin are pasted in advance with adhesives with releasing papers on it.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that adhesive is coated with releasing paper on it in advance at the positions where to dispose said respective frame pieces on the kite sheet, allowing pasting of said respective frame pieces by peeling off the releasing paper.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the secondary beams of thin plate with lower rigidity are set being overlapped with the main beams under these to extend the width of the main wing, and the length of the secondary beams are long, the plastic pipe used for the spine may be disposed on the thin plate.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the lower mounting point of the kite string to be fixed on the spine is provided at a position lower than the point where the slant beams and the spine intersect.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the kite is provided, at the end of the main beams, with longitudinal beams intersecting with the main beams, and the longitudinal beams consist of material having about the same strength and rigidity as the slant beams.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that face fasteners are symmetrically pasted on the kite paper against the kite's axis of symmetry.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that at the leading edge portion of the wing is mounted a light straight or curved slender plates made of foamed resin having the required rigidity.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the intersection of the spine and the slant beams are symmetrically pasted for example by two slender plates of foamed resin with adhesives in its one face mounting the slant beams, and any strong tape can be used in place of the slender plate.

A kite comprising a spine serving as the kite's axis of symmetry, the main beams of the wing disposed at the position higher than the aerodynamic center of the wing and orthogonal to said spine, and slant beams, characterized in that the cross-section main beams has L or U shape.

For a beginner, the seller sells a kit with the following parts:

• (a) The sheet pasted in advance with the spine attached with the strings, slant beams, longitudinal beams, secondary beams and outmost leading edge. Note that this sheet can be packed compactly by folding it.
• (b) The main beams with the spring holders with a spring fixed in one holder and the slender plates for forming the leading edge and the form of horizontal tail are cut by given length and pasted by adhesives with releasing paper on it. Pairs of small points that show the both end of them are printed on the sheet.

A selling method for the kite, characterized in that the seller distributes the respective constituent materials of the kite to the purchaser, based on a computer input of the kite desired from the purchaser.
