ABSTRACT:
A collapsible luggage cart or trolley has a telescopically-extendable handle which is coupled to a tubular-axle of the trolley wheel-assembly, and which when decoupled from the wheel assembly in the collapsed state of the trolley, is accommodated within the hollow axle of the wheel assembly. A cranked frame of the load-carrying trolley-platform is pivoted on a cross-bar that extends parallel to the axle, and an elastic tie for holding the load on the platform, loops from the extremities of two outwardly-extending side-bars of the platform over an adjustably-positionable hook on the handle. For collapse of the trolley, the cranked frame is swung backwardly to lie over the axle, and the side-bars are folded inwardly with the tie wrapped around the whole. The same sprung latch-pin as used for restraining the handle within a socket on the axle in the erected state of the trolley, is used in the collapsed state for restraining the closed-up handle within the axle.
