Abstract
A tray apparatus for a high chair wherein the tray apparatus includes a tray that is incrementally slideable to a multiple number of positions. The sliding is controlled by a hand operated knob disposed on an outer edge of the tray, a location of convenience for the caregiver. The inner sliding mechanism includes a hand operated screw having threads that engage a thread receptor in a base on which the tray slides. The tray and base are further engaged via guide portions that frictionally engage each other to minimize a free sliding of the tray and base relative to each other and maximize a controlled sliding, via the hand operated screw, of the base and tray relative to each other. The guide portions guide the sliding of the base and tray relative to each other and further lock the tray and base relative to each other. The tray and base are unlocked relative to each other by resiliently drawing one of the guide portions away from the other of the guide portions.
