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. The stopper is able to fit on and retain either of the pair of engaging arms which is selectively fitted in the distal end of the bracket.
