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.
