    Abstract: The present invention provides for an automatic swinging device with a natural rhythm of the swinging motion that is designed and configured to be coupled to any desired apparatus that can be sat on and in which the user wishes to be swung automatically, if desired, and manually, when desired. The present invention is an apparatus that can be attached to any device so as to provide for a final product that not only provides an automatic swinging motion having natural rhythm, but also provides for a unit that allows the user to swing naturally, when desired, so as to prevent hindrance of free swing, and to adjust the angle of the automatic swing motion. In an optional configuration, the present invention can include an attachment element that will eliminate wobbling during the swing motion, a feature generally associated with conventional swings. To enable such a configuration, the swing device of the present invention comprises a driving unit, an actuating unit, and a power unit.

  • Patent number: 6254490
    Abstract: An automatic swing device to be used in combination with a conventional porch swing is disclosed and includes a frame member that will support a conventional porch swing and maintain the components of the automatic swing device. Secured to the swing is a motorized rotating arm assembly. This rotating arm assembly includes a fractional horsepower gear motor. An initiation assembly is coupled to the rotating arm assembly. This initiation assembly includes a clutch arm that is connected to a stop unit. The stop unit is connected to the fractional horsepower gear motor. In operation, the user sits on the swing and pushes back, this will cause the rotating arm assembly to active the initiation assembly. The initiation assembly will provide for the clutch arm to pull back, forcing the stop unit to be disengage and cause for the automatic operation of the device.
