Definitions

  • the purpose of the present invention application is to register an improved kite, which incorporates notable innovations and advantages over the techniques used so far.
  • the invention proposes the development of an improved kite, which by its particular arrangement, adds and improves the aerodynamic and use properties to the known kites used in the practice of kitesurfing.
  • kitesurfing Typical kites used in sports such as kitesurfing are known in the current state of the art.
  • kites use and collect the driving force of the surrounding wind so that the user of a surfboard can move and perform different acrobatic stunts sliding on the surface of the water.
  • the present problem is solved and solved, since it is possible to contribute and add better aerodynamic and support qualities to the already known kites used in the practice of kitesurfing, and in particular those that are inflatable, in addition to improve and facilitate its relaunch after its fall into the water.
  • the present invention has been developed in order to provide an improved kite, of those commonly used in the practice of kitesurfing, comprising a laminar surface delimited by an leading edge and an exit edge, and a frame provided with a profile of attack and a plurality of crossbars that innervate the sheet surface, such that the attack profile innervates the sheet surface along its leading edge, and the crossbars innervate the sheet surface from the leading edge to the trailing edge and are substantially perpendicular to the attack profile, and is essentially characterized by the fact that the attack profile has a cross section of the alar or aerodynamic profile type.
  • the attack profile may be made of a single inflatable type piece.
  • the attack profile is formed by a first piece of substantially circular cross-section, and by another second piece with a suitable cross section to complete with the first piece the cross section of the alar or aerodynamic profile type.

Abstract

L'invention concerne un cerf-volant amélioré, de ceux habituellement utilisés dans la pratique du surf cerf-volant, qui comprend une surface laminaire (1) délimitée par un bord d'attaque (2) et un bord de sortie (3), et une ossature (4) dotée d'un profil d'attaque (4a) et d'une pluralité de barres transversales (4b) qui innervent la surface laminaire (1), de sorte que le profil d'attaque (4a) innerve la surface laminaire (1) jusqu'à son bord d'attaque (2), et que les barres transversales (4b) innervent la surface laminaire (1) depuis le bord d'attaque (2) jusqu'au bord de sortie (3) et soient sensiblement perpendiculaires au profil d'attaque (4a), le profil d'attaque (4a) présentant une section transversale de type profil d'aile ou aérodynamique.
