ENGINE WITH A FIXED WING ARTICULATED AT THE TOP OF A MAST.

Abstract

Engin à voile dont la voilure est une aile fixée au sommet d'un mât par une articulation et que l'utilisateur tient et manœuvre par l'intermédiaire d'un guidon situé à l'extrémité d'un manche perpendiculaire à l'aile. La coque de l'engin est équipée soit d'ailes (2) sous-marines, soit de skis reliés à la coque par les dérives (3) de sorte qu'avec la vitesse la coque sort de l'eau. En fonctionnement, l'équilibre de l'engin est assuré par l'utilisateur d'une manière analogue à la voile d'une planche à voile. Applications: Voiliers, sport et loisir de plage.

Description

The main patent (No. 88 11785 of 9 Sept. 88) describes a sailing craft whose sail is a wing fixed to the top of a mast by a joint and which is held by means of a handle perpendicular to the wing, and the present addition describes variants of this craft whose hulls are specially equipped to increase speed. This equipment consists of wings or skis fixed under the hull(s) so that the craft, supported by these elements, sinks less into the water, the hulls being able, with speed, to no longer touch the water. According to one of the variants shown in figures 1 and 2, the hull (1) (or hulls) is equipped with one or more underwater wings (2) substantially parallel above the hull arranged under the latter transversely relative to the hull and connected to it by substantially vertical or oblique fins (3). The lift plane of these underwater wings is oriented slightly nose-up so that the horizontal movement of the hull in the water creates an upward lift force. According to another variant shown in figures 3 and 4, the hull (1) (or each hull, if there are several) is equipped with a ski (4) arranged under the hull longitudinally and connected to the hull (1) by substantially vertical fins (5) and / or ailerons (6). The front of the ski is arched upwards; the front end of the tip (6) can join the front of the hull. According to another variant shown in figure 5, the hull is equipped with a V-shaped wing (7), formed of 2 oblique fins joining under the hull. With speed, the hulls of these boats come out of the water and the balance of the machines is ensured by the user by trimming the sail more or less. According to a variant shown in Figure 6, the machine has no hulls; the base of the mast (8) is fixed to a structure (9) of substantially triangular or semi-circular shape comprising on the one hand 2 wheels (10) with a common transverse axis and on the other hand, an "idler wheel" (11), that is to say a wheel whose horizontal axis is freely oriented. This machine is guided by the user using the handlebar (12) located at the end of the wing control stick, by turning the wing around this stick taken as the axis of rotation, in order to move the center of thrust of the sail in front of or behind the transverse axis of the wheels (10). Applications: Sailboats and beach craft.

Claims

CLAIMS 1. Sailing machine according to claim 1 of the main patent, characterized in that the hull(s) (1) are equipped with one or more underwater wings (2) substantially parallel above the hull, arranged below the latter transversely relative to the hull and connected to it by substantially vertical or oblique fins (3).

2. Sailing craft according to claim 1 of the main patent, characterized in that the hull, or each hull, if there are several, is equipped with a ski (4) arranged longitudinally under the hull and connected to the hull (1) by substantially vertical fins (5) and / or ailerons (6), the front end of the tip (6) of the ski being able to reach the front of the hull.

3. Sailing craft according to claim 1 of the main patent, characterized in that the hull is equipped with a V-shaped wing (7), formed of 2 oblique fins meeting under the hull.

4. Sailing machine according to claim 1 of the main patent, characterized in that the base of the mast (8) is fixed to a structure (9) of substantially triangular or semi-circular shape comprising on the one hand 2 wheels (10) with a common transverse axis and on the other hand, an "idler wheel" (11), that is to say a wheel whose horizontal axis is freely oriented.
