Self-contained traction wing

Abstract

A self-contained traction wing which is intended to be used in combination with a gliding device capable of interacting with the feet of a user, is controlled by the user via manual gripping mechanism placed on the wing, and has a structure having a sail defined by a leading edge formed by an inflatable tube, and a trailing edge, the structure being symmetrical in relation to a central batten. The half wings located on either side of the central batten, each comprise at least one additional transverse batten between the central batten and the end of the wing. The additional transverse batten is closer to the end of the wing than to the central batten and comprises an inflatable tube structure, having a length provided to create a positive trailing edge.

I claim: 
     
         1 . A self-contained traction wing which is intended to be used in combination with a gliding device capable of interacting with the feet of a user is controlled by the user via manual gripping means placed on the wing, the wing comprising:
 a structure having a sail defined by a leading edge (BA) formed by an inflatable tube and a trailing edge (BF) said structure being symmetrical relative to a central batten; and   half-wings located on either side of the central batten, each comprise at least one additional transverse batten placed between the central batten and the end of the wing,   wherein said additional transverse batten  2  is closer to the end of the wing than to the central batten  1  comprises an inflatable tube structure,   having a length provided to create a positive trailing edge BF.   
     
     
         2 . The self-contained traction wing, according to  claim 1 , wherein the leading edge (BA) is extended by wing tip battens forming an angle with the leading edge (BA). 
     
     
         3 . The self-contained traction wing, according to  claim 2 , wherein the central batten and the wing tip battens are comprised of inflatable tube. 
     
     
         4 . The self-contained traction wing, according to  claim 3 , wherein the inflatable tube of the leading edge (BA), the inflatable strand of the central batten, the inflatable tubes of the transverse battens and the inflatable tubes of the wing tip battens are connected by a common inflation system. 
     
     
         5 . The self-contained traction wing, according to  claim 1 , wherein the central batten is attached to the direct contact of the sail near its rear end. 
     
     
         6 . The self-contained traction wing, according to  claim 1 , wherein the central batten comprises a portion located between its rear end and its junction with the inflatable tube of the leading edge (BA) which is not in contact with the sail V and is connected thereto by a panel of flexible material of the fabric type. 
     
     
         7 . The self-contained traction wing, according to  claim 1 , wherein the sail V is comprised of fabric, wherein the direction of the straight yarn of the fabric is oriented, in each half-wing, at least in the vicinity of the trailing edge (BF), parallel to a fictitious line drawn between the rear end of the central batten and the rear end of the additional batten.
