ABSTRACT:
This invention relates to a manual swing drive mechanism to be mounted on a swing in order to transmit the swinging movement to a person who cannot do it alone, notably a child. Through a hand operated rocking arm, the assisting person transmits a swinging movement to a swaying member which transfers a pendulum swinging movement to the seat lines of the swing through a set of elongated swinging arms fixed perpendicularly to the swaying member. The functionality of the invention could be expanded into a multi-swing drive mechanism thus allowing one or several assisting persons to transmit a swinging movement to a group of two or more assisted persons.
