Definitions

• the subject of the invention is a basic element called a nacelle which can be used for four modes of movement: rolling, floating, sliding and flying, said modes of movement being able to be associated with the three means of propulsion:
• the nacelle according to the invention makes it possible to use a displacement machine from a mixed multifunction base element (leisure and professional) at low production cost, capable of being produced in large series.
• the priority areas of use are water, snow, air. Road towing is always possible that the gj2 solmt the other.
• the apparent contradiction between slow formulas and fast formulas is resolved by the development of a basic element which is called "pod".
• Said nacelle can be supplemented by accessories linked to the modes of movement and to the means of propulsion chosen.
• the basic nacelle can be fitted with any type of float, which makes it usable either by rowing, sailing, or with an outboard motor.
• the motorization of the nacelle with a ULM type motor allows, taking into account the steering wheel and the various commands, the use either on " water, or on snow, or on ice, or in flying version.
• the adaptation of wheels on the nacelle allows the use in sand yachting and allows towing with or without the floats, with or without the skis.
• the nacelle according to the invention has a vaulted shape with lateral supports and a forward curve allowing it to penetrate the air requiring only little energy. Stability at high speed is ensured by flaps located at the front on each side and adjustable.
• the arch shape provides lateral rigidity.
• the central box making, trunk and seat office ensures rigidity from front to back.
• the front part of the nacelle is raised to act as a bow, and to ensure a certain lift.
• the rear part of the nacelle includes the engine support and extends from the transom in order to provide clearance for the pivoting thereof.
• Said nacelle has numerous fixing points which make it possible to fix floats, suspension arms for wheels or ice skates, skis.
• the nacelle has a hole for fixing either the front fork with wheel or ice skate, or the rudder, or the tow bar. Another hole further forward makes it possible to secure the mast stay or the towing safety.
• a support allows to fix the mast foot.
• these comprise in 1'avant 1'arrière and a hole for the fixing of floats and two intermediate holes for fixing - • --- 'skis.
• fixings allow the anchoring of the suspension arms for wheels or ice skates.
• supports make it possible to receive the compression of the suspension systems.
• the rioir used for this purpose pe ⁇ r ⁇ t heap regulais.
• a hole allows the fixing of the supports 20 allowing to use the oars.
• the raised rear protrudes from the nacelle acting as stern.
• a vertical hole allows the installation of several elements such as: 25 - the motor,
• Figure 1 is a sectional view along the longitudinal axis of the basic element called "nacelle", said nacelle is mounted on three skis and propelled by an air propeller engine. Propulsion could also be carried out by a sail ( Figure 2). In FIG. 1 and in 1 and 2 the guidance and the suspension of the ski.
• Figure 2 is a sectional view along the longitudinal axis of the nacelle mounted on two floats and propelled by a sail (sailing catamaran version ) .
• Figure 3 is a sectional view along the longitudinal axis of the nacelle mounted on two floats and equipped with three wheels.
• the propulsion represented with the engine can also be made by a sail. Without floats and with the sail, this constitutes the sand yachting version.
• Figure 4 is a sectional view along the longitudinal axis of the nacelle equipped with three pads and propelled in this figure by an overhead propeller motor.
• the propulsion can be done by a sail and constitutes the ice tank version.
• FIG. 5 is a plan view, along the longitudinal axis, of the basic element known as "nacelle" mounted on two floats. This figure shows in 1-2-3-4 the anchors of the floats, in 5-6-7-8 the anchors of the skis, in 9 and 10 the anchors of the arms used to receive the wheels or the ice skates, in 11 , the hole which receives the front fork fitted with a wheel or ski or the rudder (sailing catamaran version). This hole also receives the anchor of the tow bar on the road.
• the engine pivot; the latter being pivotable so as to have an effective direction.
• the support on which connected by a gimbal comes to rest the mast foot (sail propulsion versions).
• the anchoring of the front forestay This anchor is also used to pass the pin ensuring the safety of the tow bar on the road.
• the safety pin for the motor pivot which is also used for anchoring the sail sheet.
• the 16 and 17 are the supports receiving the turnbuckles for adjusting the suspension of the wheel arms or the ice skates.
• the pedal for orienting the front flaps for stability or depth in the flying version with control of its trim on the dashboard.
• the brake pedal which is used as well for the brakes of skis, as those of ice skates, as those of the wheels, as those of the sand yachting.
• the steering wheel comprises carrying on the right the accelerator and in the center the engine rev counter. This direction directs the engine thrust by pivoting it and also directs the front fork or the rudder. This direction can only act on the front fork if you want to use the system to make the engine fixed.
• the steering wheel only rotates 180 ° so as to have a very direct and rapid steering. This steering wheel can be adjusted from front to back and allows a single occupant in sand yachting to use the rear seat for more safety.
• the holes used to receive the supports for oars and the arch supporting the rigid wing In 23 and 24, the holes used to receive the supports for oars and the arch supporting the rigid wing. In 25 and 26, the seats and their backrests for two passengers with the possibility of adjustment forwards and backwards and also the possibility of removing them entirely. The front seat backrest is removable so as to be removed in the avi ⁇ ron version and thus allow the necessary clearance. In 27, the brake booster for the rear passenger (sand yachting version with a single occupant). In 28 and 29, stability and depth flaps are used in both the fast and flying versions. The rigid wing is guyed with eye nuts in holes 1-2-3-4.
• Figure 6 is a cross-sectional view along the axis XY reselling ⁇ felt ' in Figure 5. This Figure 6 does not include the front cover or the front stabilizers.
