Abstract

A foldable cart includes a handle portion, a foldable frame movably connected to the handle, and one or more wheels for rolling on a surface. In an unfolded (in-use or open) condition, the foldable frame constructs a holding-space defining a receiving cavity therein for carrying items, and the action of unfolding the frame automatically deploys wheels to enable immediate use of the cart by the end-user or customer. In a folded (storage or closed) condition, the carts' frame folds to occupy a smaller space in one or more spatial dimensions, and the automatically deployed wheels turn to occupy smaller total space in one or more spatial dimensions. In the folded condition, the cart is easy to store in a small space (e.g. in a small closet, under a bed, etc.) or transport (e.g. in the trunk of an automobile, vehicle, airplane, train, ship with a courier, etc.).
