ABSTRACT:
A lifting device and method therefore utilizing an air bag or the like for lifting an object supported by a wheeled platform or the like, from a stationary, parked configuration wherein the object conceals the wheeled platform and supports the object, to a lifted, configuration whereby the wheeled platform supports the object, allowing same to be easily moved via the wheeled platform. The preferred embodiment of the present invention contemplates a planter unit comprising a pot or the like for containing a plant, said pot having a false bottom wherein there is situated a support platform having castors or the like thereon, and an air bag or other flexible container configured to be filled with fluid situated between the wheeled platform and the underside of the pot. In use, the false bottom has a cavity formed therein to enclose the wheeled platform, the false bottom having a lower edge supporting the pot when the air bag is uninflated. To lift the pot and raise the lower edge of the false bottom from the floor, the air bag or the like is filled with air via a hand pump or compressed air source, which expands the bag so as to lift the planter such that the wheeled support then supports the planter. The walls forming the false bottom surround the air bag in its inflated condition, stabilizing the unit so that it may be wheeled to its desired location, and preventing “rolling” of the airbag and planter from the platform.
