WAVE-MOTION INFANT SEAT

摘要

A first rotate/translate mechanism, a second rotate/translate mechanism, a drive system, and a control system are operable to generate and impart rotation and translation to an infant-receiving component supported by a frame thereby driving the infant-receiving component through an elliptical wave motion. In an example embodiment, the first rotate/translate mechanism includes a cam that is driven by the drive system and a follower that is driven by the cam to impart the rotation and translation to the infant-receiving component. And the second rotate/translate mechanism includes guided traveler that is guided by a guide track through conforming rotation and translation to permit the wave motion of the infant-receiving component without binding.

主权项

1. An infant seat for use on a support surface, the infant seat comprising:
a frame that is supportable by the support surface; an infant-receiving component that is supported by the frame; a first motion mechanism coupled between the infant-receiving component and the frame, the first motion mechanism including a follower and a cam that drives the follower to impart motion to the infant-receiving component to trace an elliptical path defining a wave motion; a second motion mechanism coupled between the infant-receiving component and the frame, the second motion mechanism including a guide track and a guided traveler that moves relative to the guide track to facilitate the motion of the infant-receiving component; and a drive system that is selectively operable to drive the first motion mechanism to produce the wave motion of the infant-receiving component.
