Abstract

An expression mechanism for a toy having a lower lip, a cheek and an eye, includes a support frame, a lip lever pivotally connected to the support frame for engaging the lower lip of a toy, a cheek lever pivotally connected to the support frame for engaging a cheek of the toy, an eye linkage for opening or closing the eye of the toy, and a motor for actuating one of the lip and cheek levers to cause the toy to simulate a facial expression. The lip and cheek levers are interconnected in a manner that when the cheek lever pivots in one direction, the lip lever pivots in a generally opposite direction. The expression mechanism causes the toy to assume various facial expressions, including, but not limited to, smile, frown, and neutral.
