Abstract
An extender unit for an infant walker in which the unit is adapted to extend laterally outwardly away from the walker base. The unit is formed of a plurality of extender segments which can be releasably locked to each other and to the walker base by wheel inserts having one-way locks. Wheel assemblies are inserted into the wheel posts on the extender unit. The extender segments, wheel posts, and wheel assemblies can be shipped separate from the infant walker and assembled to the walker at a use site. The walker device cannot be used by an infant without the extender unit because all wheel assemblies are mounted in the extender unit.
