Abstract
Abstract In a gearing for the locomotion of toy figures between two end positions the gearing is formed as string drive with two string wheels mounted on a common shaft pivoted in bearing in the body of the toy figure and respective one string belonging to each string wheel, which string is mounted with the one end at the belonging string wheel and can be gripped with the other end, both strings being partly windable on the belonging string wheels and are tensionable in a direction opposite to one another and whereby furthermore in the end positions of the toy figure the one string respectively is wound up onto the string wheel belonging to it, the other string thereagainst is wound off.

Independent Claim
306 words
A drive mechanism for a climbing toy comprising a housing, a first crankshaft, means for mounting said first crankshaft for rotation within said housing, said mounting means preventing axial displacement of said first crankshaft relative to said housing, a second crankshaft, means for mounting said second crankshaft for rotation within said housing, means for operatively connecting said first crankshaft to said second crankshaft such that rotation of said first crankshaft imparts rotation to said second crankshaft, a first string wheel having a first diameter and connected to said first crankshaft, a second string wheel having a second diameter smaller than said first diameter and connected to said first crankshaft, a first string connected to said first string wheel and adapted to be wound and unwound therefrom, a second string connected to said second string wheel and adapted to be wound and unwound therefrom, said first string and said second string connected to their respective string wheels such that when said first string is wound on said first string wheel said second string is unwound from said second string wheel and such that when said first string is unwound from said first string wheel said second string is wound on said second string wheel, a first aperture in said housing enabling said first string to pass from said first string wheel through said housing, a second aperture in said housing enabling said second string to pass from said second string wheel through said housing, and guide means disposed over said first string wheel and said second string wheel and rotatable therewith, said guide means defining a first slot for guiding said first string as said string is wound and unwound on said first string wheel and defining a second slot for guiding said second string as said string is wound and unwound on said second string wheel.
