Abstract: A driving device is adapted for an infant rocking chair. The rocking chair includes a seat body and a bottom seat. The driving device includes a base, a supporting element, first and second motion mechanisms, and a power mechanism. The first motion mechanism includes a horizontal first guide path unit disposed at the bottom seat, and a first movable member disposed on the base and movable along the first guide path unit. The second motion mechanism includes a vertically varying second guide path unit disposed at the bottom seat, and a second movable member movable along the second guide path unit and vertically relative to the base. The supporting element interconnects fixedly the seat body and the second movable member. The power mechanism drives reciprocal movement of the first and second movable members.

Abstract: An infant seat rocker includes a base member having a pair of rails that protrude generally vertically from the base member and extend a length of the base member, a motor that is positioned on the base member and means for attaching the motor to the infant seat. The infant seat is positioned on the base member with the rails capable of locating the infant seat on the base member and the motor is engaged to produce and maintain a rocking motion in the infant seat.
Abstract: Longitudinal and rotational movement of a rocking chair during the rocking motion is substantially prevented with a rocking chair having a pair of transversely-spaced, generally longitudinally extending rockers that converge at a first angle. A base is provided having a pair of transversely-spaced, generally longitudinally extending channels that converge at a second angle at least approximately the same as the first angle. The channels are positioned to underlie the rockers as the rocking chair is rocked. The transverse width of each channel is sufficiently wider than the transverse width of the respective rocker to accommodate the rocker within the channel during rocking motion of the chair, and is sufficiently narrower than the transverse width of the respective rocker to prevent substantial longitudinal movement of the rockers within the channels.
