Abstract
Abstract A crib toy having a shaped outer shell with a downward facing U-shaped aperture adapted to fit over a crib rail. The shell houses an automatic reversing mechanism which drives an output roller positioned in the aperture for moving the toy back and forth along the rail. In a preferred embodiment, the reversing mechanism includes a motor which rotates first and second cam surfaces at a first speed and first and second cam followers at a second speed causing the cam followers to drive first and second gears to operate the output roller. The preferred embodiment combines a music box with the reversing mechanism to provide a synthesis of music and movement for a child.
