Title (EN) NAUTICAL PROPULSOR DEVICE
(FR) PROPULSEUR NAUTIQUE
Abstract: front page image
(EN)The propulsor device comprises blades (9) arranged at the end of blade carriers (8), said blades being driven approximately in a motion of translation within a vertical plane by means of a mechanism for the transmission of the circular motion of a cranked gear (6), said mechanism being carried by a frame and comprising a bar (7) hinged at a crank (15) on the first and of the blade carrier (8). Said mechanism comprises a pair of rods (10, 11) connected to one of their ends respectively to said bar and to said blade carrier, and hinged one to the other at a rod connection point (14), the rod (10, 11), the bar (7) and the blade carrier (8) forming a deformable quadrilateral, whereby said mechanism allows to carry away the blade well in front of the pedal gear. The device is particularly appropriate for use in pleasure boats such as pneumatic rafts or boats.
(FR)Propulseur du genre comportant des pales (9) disposees en bout de porte-pale (8), lesdites pales etant mues approximativement en translation dans un plan vertical au moyen d"un mecanisme de transmission du mouvement circulaire d"un pedalier (6), ledit mecanisme etant supporte par un chassis et incorporant une tige (7) articulee en un coude (15) a la premiere de ses extremites en bout du porte-pale (8). Selon l"invention ledit mecanisme incorpore en outre un couple de bielles (10 et 11) reliees a une de leurs extremites respectivement a ladite tige et audit porte-pale, et articulees l"une sur l"autre en un point d"articulation de bielles (14), les bielles (10 et 11), la tige (7) et le porte-pale (8) formant de ce fait un quadrilatere deformable, d"ou il resulte que ledit mecanisme permet de deporter la pale bien en avant du pedalier. L"invention est particulierement applicable aux embarcations de plaisance du genre radeaux pneumatiques.
