Abstract
A baby walker includes a seat supported by a tray for surrounding a child in a standing position, and permitting the walker to move with the child as he walks, and for supporting a child in a seated position, a friction pad on the walker for selectively engaging the surface upon which the walker is supported for selectively inhibiting movement of the walker, a plurality of supporting wheels on the walker for supporting the walker for rolling translation on the supporting surface, and an adjustable suspension coupled between the walker and one or more of the supporting wheels for selectively actuating one of three modes of operation, namely a first mode in which the friction pad engages the surface substantially continuously for inhibiting movement of the walker, a second mode in which the walker is movably supported on the wheels when the child is standing and is supported on the friction pad means for inhibiting translation when the child is seated, and a third mode in which the walker is continuously supported on the wheels for rolling translation over the surface.
