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.

Abstract: A guard for a baby carriage in which armrests have fitting holes facing a front surface and a guard has fitting pipes which are insertable into these fitting holes. Each of the fitting pipes has a biased tab which is engageable with a engagement hole at the side of a cylidrical hole at the back of the fitting hole. An opening button, at the bottom of the arm rest, releases the biased tab for the removal of the guard. Planar covers with rear projections are fittable into the fitting holes.

Abstract: A folding and lock mechanism for a pushcart includes a bracket pivotally mounted at its proximal end on a rear face of a rear leg intermediate opposite ends of the rear leg so that the bracket can be pivotally moved along the rear face of the rear leg between a generally upstanding position and a lower position. A retainer plate is formed on a lower end of a handle grip, and has a bifurcated end of a generally L-shape or inverted Y-shape defined by a pair of engaging arms. The retainer plate is pivotally connected to the distal end of the bracket at that portion of the retainer plate where the pair of engaging arms merge together. One of the two engaging arms is fitted in a groove formed in the distal end of the bracket to maintain the assembled condition of the pushcart whereas the other engaging arm is fitted in the groove to maintain the folded condition of the pushcart. A tubular stopper is fitted on the distal end portion of the bracket and is slidingly movable along the bracket.

Abstract: A shopping pushcart includes an article-holding container mounted inwardly of a frame and having an open top. A lid plate is mounted through a link above the open top of the article-holding container in such a manner that the lid plate can be moved to a generally upstanding position and can also be reversed. Opposite faces of the lid plate serve as a lid surface and a seat surface, respectively.
