ABSTRACT:
A foldable apparatus of a baggage cart includes a base plate, two elongate sockets formed on the base plate substantially along two sides thereof. A first cutout, a second cutout, and a third cutout are defined in each elongate socket and are substantially in alignment with each other. A flange is projected from a wall of the first cutout. A channel is defined in the socket and in communication with the first cutout, the second cutout and the third cutout. A pivot is pivotally received in the channel and having two ends thereof extending outward from the channel, where one end is integrally formed as a substantially U-shaped bracket which has an upright branch connected to a curved portion connected to a inclined branch, while the other end is formed as an upright rod which has a wheel rotatably connected thereto. A recess is defined in a low portion of a wall of the second cutout, and being sized to be capable of receiving an end portion of the inclined branch of the U-shaped bracket. The foldable apparatus is operable to be in an extended mode for transportation, where the upright branch is retained in the first cutout by the first flange and the upright rod is retained in the third cutout by the second flange, or in a retracted mode for storage, where an end portion of the inclined branch is received in the recess.
