摘要： A hand-propelled cart with side wheels, and a rear caster leg foldable under the frame of the cart. The caster leg is freely pivoted and actuated by means of a hand lever to fold, a camming latch operating automatically to lock the caster leg in the folded position. A plunger is located in the rear of the cart, and operates a device when depressed to release the latch and allow the caster leg to drop to standing position; and another latch automatically locks the caster leg in such position.
