摘要:
A screw drive vehicle (10) has a main housing (20) with forward and aft ends (22, 24), and first and second lateral sides (26, 28). A first support arm (72) rotatably supports a first pontoon assembly (70a) from the first lateral side of the main housing. A second support arm (72) rotatably supports a second pontoon assembly (70b) from the second lateral side of the main body. A reversible motor (50) in the housing simultaneously rotates the support arms from positions parallel to one another and the main housing to non-parallel positions. Each pontoon assembly includes a tubular housing (82) with exterior screw thread (84) supported for rotation between distal ends of the arm and a reversible pontoon drive motor (130) operably coupled with the tubular housing so as to rotate the housing and thread in a selected rotational direction.

The invention relates to a marine propulsion system and describes a marine propulsion system with improved efficiency, which leads to reduced wave formation, comprising an at least partly submerged forward propulsion unit, rotating around at least one axis, running essentially perpendicular to the propulsion unit and a cover, at least partly enclosing the propulsion unit, which, on operation of the propulsion unit, forms, together with the propulsion unit, a flow channel, delivering the water.

On utilise un pneu pour assurer la flottaison et la propulsion d'un tricycle aquatique a pedales ou d'un vehicule de loisir similaire. Le pneu est gonflable afin d'obtenir une structure gonflee (10) presentant une pluralite de saillies ou nervures (13) qui s'etendent transversalement sur la region externe du pneu et sur une partie des regions laterales du pneu. Les saillies ou nervures agissent comme des pales et propulsent le tricycle sur un plan d'eau tel qu'un lac ou une piscine. Selon une variante, ou en supplement, la roue du vehicule presente une structure formee par une pluralite de rayons en forme de lamelles (44), qui viennent se longer dans des fentes (42) placees autour du moyeu (40) et qui presentent une region externe (46) entourant une partie d'un pneu (49) Selon une autre variante, une roue du vehicule peut etre construite en un materiau rigide afin de presenter une region de moyeu (52) et une region de pneu (51), avec des ailettes formees sur au moins un cote de la region du pneu (51).

La présente invention concerne des perfectionnements aux flotteurs hélicoides rotatifs destinés à équiper des engins nautiques ou autres. Le flotteur hélicoide selon l'invention présente une forme générale inscrite dans un cylindre doté d'au moins un sillon (1) ménagé en creux se développant sur tout ou partie du flotteur suivant une hélice et présentant une partie avant (2), une partie centrale (3) et une partie arrière (4) et se caractérise essentiellement en ce que la partie avant (2) est égale à la longueur du pas du ou des sillons (1) divisée par le nombre de sillons.
