Abstract
An open top baby swing having a frame which in turn includes legs and a base and wherein the legs of the frame extend from only a front portion of the base. A transition from the base to the legs is integral so as to provide a solid frame. Upper ends of the transition are tied together with a cross member. A swing mechanism for controlling swinging of the baby seat includes two drive trains isolated from each other by a coil spring. Any movement or ceasing thereof by one end of the first drive train exerts a respective movement or ceasing thereof on the end of the coil spring to which the other end of the first drive train is engaged, and vice versa. Any movement or ceasing thereof by one end of the second drive train exerts a respective movement or ceasing thereof on the end of the coil spring to which the other end of the second drive train is engaged, and vice versa. A control unit for the swing mechanism includes a bank of lights running in a line that is user friendly.
