FR2462338A1 - Outrigger stabiliser for sail-board - has hinged arm connection to allow float vertical movement - Google Patents

Abstract

The craft is fitted with a central hull (1) carrying two out riggers (10,11) and joined to the hull. The joint has a bracket which encircles the hull. The bracket has an edge clip (6,7) along each edge. These clips receive the arms (8,9) which hold the floats at the outer end, The clips are hinged so that the floats can move vertically on the arms. The floats are fixed to the arms and hull during fabrication, by screwing through the hull or float.

Description

 The object of the invention relates to a stabilizing device for windsurfing.

 I1 is intended given the removability of the frame to be mounted both during manufacture and on any existing board, without preventing its traditional use, while avoiding falls and increasing control of the machine.

In current devices, removable or fixed fins are used to ensure a certain stability, but the inevitable imbalances mean that the user spends a longer immersion time than the navigation times, especially for beginners. these difficulties make the entries and exits of the areas delimited on the edge of the beaches uncontrolled and generating accidents.

 The device according to the invention eliminates these disadvantages and allows ease of initiation for beginners, stability at sea improved in all weathers and the reduction of falls.

 I1 is constituted by a fiXe or removable combination mount encircling the hull and supporting perpendicular arms integral with their ends of profiled floats.

In the accompanying drawings, given by way of nonlimiting example, i - one of the embodiments of the subject of the invention:
Figure 1 shows seen in plan, the device as a whole.

 Figure 2 is a perspective view of the assembly of floats.

 Plate 1, FIGS. 1 and 2 has at its middle part a frame 2.

 This frame in the example given, has two lateral strapping elements 3, 4.

These lateral jaws are connected by a turnbuckle 5 ensuring their blocking in the functional position, each jaw com carries an endpiece 6, 7 receiving the arms 8, 9. The load-bearing end of these arms is secured to the floats 10,11.

The inclination of the arms 8, 9 is obtained on the ball ends 6, 7 varying in the vertical plane the position of the floats which will be blocked at the desired angle.

 The fitting of the connecting bars can be achieved during manufacture by the provision of molded panels inside the body of the windsurfing board.

The holes can be closed in the event of non-use to give the board its original shapes.

These floats which can be installed at a higher level than the board, will only fulfill their role in the event of a pronounced inclination by deflecting the tilting.

 The user will therefore use his machine exactly as if they did not exist and will reduce the falls in considerable proportions.

 The forward speed will not be reduced and the sportiness of the machine preserved.

 The courses can be increased and the windsurfing will then constitute a real sailboat obeying the impulses of the navigator with more flexibility and precision.

 The risk of accidents will be reduced for both the user and the surrounding third parties, given the precision of the maneuvers and the control of the boat.

It is possible to perforate the floats in the horizontal and longitudinal plane to achieve ballasting without reducing the buoyancy.

 Finally, these floats constitute lifelines, and give the possibility of transporting a person lying across without submerging the boat.

However, the shapes, dimensions and arrangements of the various elements may vary within the limit of the equivalents, as moreover the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
