Abstract: A portable and collapsible luggage carrier having an upright frame including a lower frame section and an upper frame section pivotally connected to the upper end of the lower frame section. Wheels are secured to the lower end of the lower frame section and the ends of legs of a U-shaped base frame are pivotally connected to the lower frame section so that the base frame is swingable between a generally horizontal, operative position and a generally vertical, inoperative position between the side portions of the lower frame section. A pair of U-shaped auxiliary support frames are pivotally connected to the legs of the base frame and an extension frame is shiftably mounted on each auxiliary support frame. When the base frame is in its operative position, the auxiliary support frames are engaged with the legs of the base frame and the extension frames are extended, the lateral stability of luggage supported on the carrier is substantially improved.
