FR2791318A1 - Paddle drive for marine vessel has frame supporting engine and rollers mounted eccentrically to engine shaft to rock drive shafts for paddles - Google Patents

Abstract

The paddle drive for a marine vessel has a frame supporting the engine and two rollers (2) mounted eccentrically to the engine shaft. The drive shafts (5) have openings receiving the rollers at one end and are connected to the paddles (10) at their other ends. The shafts pivot around a support shaft (6).

Description

The invention relates to a mechanism tending to innovate in the field of nautical sailing.

The di, 5po, 3iìl technique of the invention tends to be in the mode of 2ou2s.on actue, ca2acté2.isé pan the transformation of pui3, driving jance in pnopue-6ive force rectilinear continuous pan the action of a propeller .
