Abstract
A folding and locking mechanism for a folding baby chair, the mechanism locks the chair in an assembled and folded condition and is unlocked from either condition by the same simple manual operation. A bracket pivotally connected between a rear leg and a support arm locks in two respective positions on a retainer pin which rides on the bracket periphery and is received by a pair of retainer recesses, one for the assembled condition and one for the folded condition. The retainer pin is held by a locking lever that pivots and moves up and down in a holder frame within the support arm. Movement of the lever upward by a simple manual action urges the retainer pin away from the bracket, allowing the bracket to rotate to thereby fold or assemble the chair. A descending operating plate holds the upwardly urged locking lever in the up position until the bracket begins to rotate.
