A pallet or cart which can be coupled to a similar pallet or cart in a side by side relationship is disclosed. The pallet or cart, at its one or right side, has a coupling, which cooperate with an associated coupling on the opposite or left side of an adjacent pallet or cart. The couplings and the associated couplings can be connected to connect the two pallets or carts together to make them capable of being moved together, and even be lifted and lowered together by a standard lift truck or fork lift or a standard pallet jack. The couplings are also releasable so that, when necessary, each pallet or cart may be used as would be a single pallet or cart. The pallet or cart may have one or more foldable shelves therein.

1. A cart for moving items from one location to another over the ground adapted to be connected to an identical cart, said cart having a height of at least 48 inches, said cart having adjacent one side coupling means which are adapted to connect to associated coupling means on another of the identical cart, said cart having adjacent its other side associated coupling means which are adapted to connect to coupling on one side of the identical cart, said coupling means and associate coupling means forming at least a top coupling located on an upper half or higher of said cart, said cart having a bottom having a ground clearance of at least 5 inches said bottom having structure extending from said bottom to locate a tang of the standard lift truck generally centrally of the bottom and being capable of accommodating and receiving one of the tang of the lift truck or the pallet jack and be lifted off the ground by the tang or pallet jack, said cart having at least three wheels upon which the cart can stand alone and be moved over the ground, alternatively, said cart wheels being lifted off of the ground by one of a single standard lift truck with two tangs, one of which is under the cart and the other of which is under the identical cart, and a pallet jack, said cart having at least two sides formed of generally vertical sidewalls cooperating with said bottom for forming an interior of the cart adapted for containing the items, at least another side or top of the cart provides access into the interior said cart, when connected together said cart and identical cart are adapted to be lifted, moved and/or lowered by one of said single standard lift truck with a two tang fork and pallet jack which engages both said cart and identical cart, said coupling means and associate coupling means when coupled together permitting the coupled carts in balance to move on the ground, be raised, or lowered, moved over the ground by one of the single lift truck or pallet jack, without toppling over, with the wheels off the ground, and when disconnected the cart can be used individually and moved with its own wheels engaging the ground. 2. A cart as in claim 1, wherein said coupling means and associated coupling means including a bottom coupling. 3. A cart as in claim 1, wherein said cart accepts said tang of lift truck in one direction and said pallet jack in a generally perpendicular direction. 4. A cart as in claim 1, wherein said coupling means and said associated coupling means have connecting positions and non-connecting stored positions. 5. A cart as in claim 1, wherein said coupling means is adapted to act on a part of the structure of the identical cart which forms the associated coupling means. 6. A cart as in claim 1, wherein a foldable shelf is provided in the cart. 7. A cart as in claim 6, wherein said cart has four wheels, and said shelf can be folded generally vertical against the cart out of the way, or folded horizontally to function as a shelf. 8. A cart as in claim 7, wherein said cart and shelf have hinge means to permit the shelf to pivot, and latch means to hold the shelf in its folded and unfolded positions. 9. A pair of carts as in claim 1, wherein two of said carts are connected to each other in a side by side relationship, said coupling means and associated coupling means being releasably connected together to side by side join said carts. 10. A method of building a cart and pallet for moving items from one location to another over ground, and connecting to another identical cart, comprising the steps of: providing a bottom to the cart, providing at least two generally vertical sidewalls to the cart, forming an interior of said cart by said bottom and said at least two sidewalls for containing items in said interior of said cart; providing an access to the interior of the cart for loading and unloading items, providing a height above the ground of at least 48 inches to the cart, providing a clearance above the ground of at least 5 inches,providing coupling means on or adjacent one side of one of the cart and which are for connecting to associated coupling means on the other side of the identical cart providing associated coupling means on or adjacent the other side of the cart which are for connecting to coupling means on the one side of the cart, locating said coupling means and associated coupling means on an upper half or higher of said cart, forming at least a top coupling with said coupling means and said associated coupling means, providing two of said carts, coupling the two carts together using said coupling means and associated coupling means, providing at least three wheels on the cart, providing structure on said bottoms on the carts accommodating and locating one of the two tangs of the standard lift truck under the center of the cart for raising, moving and/or lowering the coupled carts, and also accommodating a pallet jack for raising, moving, and/or lowering the coupled carts, moving the carts either coupled together either with the wheels on the ground, with said wheels off the ground with both, alternative, a two tang standard lift truck or a pallet jack, and or uncoupling the carts and moving the carts individually with said wheels in contact with the ground. 11. The method of claim 10, comprising the step of coupling the two carts side by side together using said coupling means and associated coupling means. 12. A method of restocking a store and for moving items from a first location to a second location with a pair of identical carts, each with at least three wheels, each with coupling means for connecting said carts together, using one of a standard lift truck with a two tang fork or a pallet jack, said carts having structure to center a tang under the cart, said cart having an interior formed by said bottom at least 5 inches above this ground and at least two generally extending sidewalls for containing said items, an access to load and unload items into and from the interior, said sidewalls being at least 48 inches in height, said coupling means being at least half the height or higher than the height of the sidewalls, comprising the steps of: moving the pairs of cart separately or coupling two carts together and;moving the coupled carts together while one of filling the carts and/ormoving them to a place for transport, at the first location locating one of the two tangs of a standard lift truck or pallet jack under the center of each of the coupled carts for raising, moving and/or lowering the coupled carts, and also accommodating a pallet jack for raising, moving and/or lowering the coupled carts;raising coupled the carts with both, alternatively, one of a standard two tang fork lift or pallet jack with one of the tangs under each one of the pair of carts,lowering the coupled carts for transport into a truck, disengaging the tangs or pallet jack from the pair of carts,transporting the carts to the second location by truck,raising the coupled carts in the truck,moving the coupled carts from the truck into the second location,lowering the coupled carts at the second location, and if desired using the coupled carts for restocking at the second location, by alternatively,uncoupling the carts for using and moving them uncoupled and individually with the wheels on the ground, or moving the carts at the second locations either coupled together either with the wheels on the ground, or with said wheels off the ground with, alternative, a two tang standard lift truck or a pallet jack, for restocking at the second location. 13. A pair of carts as in claim 1 connected together in a side by side relationship. 14. A pair of carts as in claim 13, wherein said pair of carts bottoms accept said tang of lift truck in one direction and said pallet jack in a generally perpendicular direction. 15. A pair of carts as in claim 13, wherein said coupling means and said associated coupling means have connecting positions and non-connecting stored positions. 16. A pair of carts as in claim 13, wherein said coupling means on one of said pair of carts acts on part of said other cart. 17. A pair of carts as in claim 13, wherein a foldable shelf is provided in each of the carts.
