ABSTRACT:
A baby walker comprises a travelable frame, a table positioned above the frame for supporting the trunk of an infant, and a plurality of support legs interconnecting and supporting the frame and the table. Each of the support legs is divided into an upper leg portion and a lower leg portion connected together by a joint so as to be foldable into the space between the table and the frame. The joint has a bearing portion and a pair of restraining walls formed on the opposite sides of the bearing portion and bent inward as opposed to each other. One of the leg portions of the support leg has a pair of support portions and pivot portions inwardly projecting from the support portions respectively, the support portions being movable toward and away from each other and biased at all times outward away from each other. The pivot portions are turnably supported by the bearing portion of the joint. With the support portions gripped by the restraining walls of the joint, the upper and lower leg portions are held in place against folding. When the support portions are pushed inward toward each other out of engagement with the restraining walls and pivotally turned over on the joint, the upper and lower legs portions are folded, thereby bringing the table and the frame over each other, whereby the walker is collapsed to a compact form.
