摘要: A rope pulling device which is compact in size which includes a housing adapted to be fixed to an exterior object. A rope is to be physically placed between a pair of cog wheels which are biased into continuous contact with the rope surface. Each of the cog wheels are operatively driven by separate driven gears with each driven gear being rotatably mounted on a plate. Each of the plates are interconnected to move together to mirror image angular positions through a cam means. Each of the plates are also pivotally mounted upon the housing. A handle means is rotationally mounted upon the housing and is operatively connected to drive a drive gear which, in turn, is operatively connected to drive each of the driven gears in the same direction of rotation at the same angular velocity. Upon operation of the handle means, the driven gears are rotated simultaneously which causes linear movement of a rope placed therebetween with respect to the housing.
