Apparatus for supporting a small child adapted to allow linear and rotational movement

摘要

A frame having vertically extending corner posts and horizontal rails therebetween in a rectangular configuration. A support plate positionable in a horizontal orientation with parallel lateral side edges and a circular hole through the center thereof. A child seat positioned within the hole of the support plate. Linear bearing surfaces formed by horizontal slots on facing surfaces of the horizontal rails and the lateral edges of the support plate received within the slots to allow for the smooth linear sliding movement of the plate with respect to the frame. A circular bearing surface formed between the inner edge of the hole and the outer edge of the seat to allow smooth rotational movement of the seat.
