International ClassB66D 003/00AbstractA compact, foldable, portable luggage carrier made of lightweight aluminum which when folded is light enough for easy hand carrying and storing. The apparatus is especially helpful for persons without sufficient strength to load luggage e.g., into an automobile trunk. The carrier is a rectangular platform on wheels with a handle structure containing a winch and pulley arrangement attached near one end of the platform. The handle structure comprises two upright posts attached at one end perpendicular to the platform and at the other end to the bottom ends of two additional posts supporting a winch, pulleys with a rope and hook for lifting the luggage and depositing it to a desired place, e.g. an automobile trunk and at the top end is a pulley arm parallel to the platform. The winch is manually or battery operated. The pulley arm's height from the platform is vertically adjusted by adjusting the top posts positions relative to the bottom posts. The platform fits under the rear of an automobile so the luggage can be deposited into the automobile trunk after it is lifted off the platform by the pulley hook and is lifted from the trunk and deposited onto the platform for transport to a desired location. The pulley structure is foldable to the upper posts which are foldable to the lower posts. The folded together posts are separable from or foldable onto the platform enabling the whole structure or each separable unit to be hand carried by the user to a desired location.Field of SearchRaising or lowering of load or load holder includes vertical, rectilinear movementAnd carrier or mover includes means enabling additional movement having horizontal component Hoist having traversing (i.e., horizontal) movement Having boom pivotable about a vertical axis Elevator with laterally shiftable guides Means comprises elevatable load-supporting portion traveling in path including vertical, rectilinear movement Cable hoist Service station type Having rotatable, cable guiding, pulley wheel element spaced from drum Element repositionable relative to drum | |
