Abstract: The invention offers a mechanism for assisting with starting and propelling a rolling object (2), pushed or pulled, by a translational action on its manoeuring member (push bar 1). The mechanism is driven by the translational movement of said manoeuring member (1) and turns at least one wheel (4) of said rolling object, via a freewheel system.
Abstract: The invention relates to a transmission mechanism with step-down reduction, in which an open belt (2) twists around a driving pulley (1) while being unwound from a driven pulley (2).
