Abstract

The sailboard comprises a first half made of metal or of plastic material 2 and a second half made of one or of a number of long inflatable partitioned bolsters 3, 4 which are let in and protected partially in the part made of metal or of plastic material and by a cloth.

Description

INFLATABLE MIXED SAILBOARD
The present invention relates to a mixed windsurf board which is formed, lengthwise
a first metallic or plastic half covered or not with a flexible coating which constitutes the upper part of the mixed board, and
a second half, consisting of one or more long tubes preferably made of light neoprene fabric or teflon, inflatable, placed side by side horizontally.

 The tubes are not interconnected. The board does not require the use of stiffeners, nor stiffening panels, shaping wall, removable or non-removable reinforcements to keep the strands inside.

 These tubes whose cut is not circular but oval, oblong or slightly rectangular are inflated to the maximum and have an inflation valve at their end. They are partitioned for safety, built-in and protected.

 The metal or plastic part is rigid, and can constitute either the deck of the mixed board or the hull, or the bottom with or without keel, covered with a flexible coating of neoprene or teflon (ship's sail). no external inflatable protective edge required.

 The rigidity of the board is obtained by the bridge and / or the hull which are made of metal, without reinforcement or ribs in the lateral direction.

 The present windsurf board remains rigorously rigid and is neither foldable, nor rollable, nor removable, nor removable for its handling and transport.

This formula makes mixed windsurfing twice as light, at least, than an ordinary board made entirely of rigid plastic, and the weight gain acquired, from simple to double, or even from simple to triple, which gives it - the same rigidity as a classic board on water, and a great
robustness, - superior lightness, - a considerable increase in the carrying surface, - qualities of very high buoyancy, and makes it highly competitive in sporting terms.

 The description which follows and the figures relating thereto are intended to illustrate preferred embodiments of the invention without being limiting in nature.

 The bridge can also be made of plastic, and such as: polyester resin, polyethylene, or any other plastic material.

 The metal or plastic bridge is covered with canvas or not, or with a neoprene or Teflon coating (type ship canvas) - ref. 3 - 4: Inflatable part, with a flat or round bottom, in long flange fabric (s), partitioned inside to meet safety standards.

These long sausages are in one piece or block, almost the length of the board., Flaring at the end of it but partitioned in several places of their length. They are inflated to the maximum, and their cut is oval, oblong or substantially restangular with wide flaring on the sides. Their inflation valve (16) is located at the rear; - ref. ll: Keel,
