Light cart with a sail made from a chassis of a specific shape, and allowing the possible use of sail elements from a windsurf board

摘要

The present invention relates to a wind-propelled vehicle, resting on means allowing its movement such as wheels, floats, skids or skis. The description which follows concerns, by way of example, the manufacture of a light cart with a sail, main application of this invention. This vehicle is constituted by a light chassis made from a tube base, which falls within a triangle, apex at the front and base at the rear, and resting in the area of each apex on a means allowing its movement (here wheels 17, 18, 19). The particularity of the chassis resides in the shape of its main structure 14, 38, 39 which is "star-shaped" seen from above, and a recumbent "S-shape" seen from the side, allowing better seating and better freedom of movement of the pilot. This vehicle is also designed in order to allow the possible use of sail elements of a windsurf board, and comprising mast 1, sail 9 and wishbone 12. Moreover, the wishbone 12 is used as a simple boom, and in contrast to normal practice for a light cart with a sail, the mast is stayed with cables 2, 3, 4. IMAGE
