Abstract: A round table cart for moving round tables along the ground. Uniquely, the invention has a first and second side support, each having a bottom, top, front and rear location. There is a ramp, connected between the first and second side supports at the bottom and front location. A pair of pivot wheels are connected to the first and second side supports near the rear location. A support bar, coupled between the first and second side supports proximate the ramp. A pair of swivel wheels, connected to the first and second side supports at that location. The table cart specifically is designed to have a first position that positions the ramp and the pair of pivot wheels on the ground, while maintaining the pair of swivel wheels off of the ground so that a round table can be loaded onto the round table cart.

Abstract: A stackable shopping cart (1) has a rolling frame (2), a basket (8), a pushing device (19), and a wall (10) that can be swiveled into the inside of the basket, through which wall the back (9) of the basket (8) can be closed, whereby two upwardly directed carriers (6) are positioned on the back end of the rolling frame (2), and the basket (8) is provided at its back (9) with support elements (13) that form a push-on connection with the carriers (6). The support elements (13) are formed by hollow receptacles (14) and the carriers (6) extend upwardly beyond the receptacles (14), and that the sections (7) of the carriers (6) located above the receptacles (14) are intended for the attachment of the pushing device (19).

Abstract: A method and apparatus for stacking two or more trailers (10) that are used for transporting containers. Each of the trailers (10) has recesses (48, 50) positioned directly over the rear wheels for receiving the rear wheels (34) of a trailer (10) stacked thereon. Smaller recesses (60) are provided adjacent a front end of the trailer for receiving a wheel (46) carried on the lower end of a landing gear (42) of the trailer (10) stacked thereon. The trailer can be stacked upon one another for storage.

Abstract: A rollercarriage having a carriage bottom below which a plurality of wheels (3, 5) is mounted, at least one of the wheels being mounted swingably about a substantially vertical swivel axis (7) which does not intersect the axis for the rotation of the wheel. The roller carriage is moreover provided with retention means to retain the at least one swingably mounted wheel (5) on an overlying roller carriage. The retention means comprise a support face (8) which supports the swingably mounted wheel at a support point (18), an outer engagement area (16) extending at least partly about the swivel axis (7), and an inner engagement area (16) positioned between the swivel axis (7) and the outer engagement are (16), said outer and inner engagement areas restricting the rolling movement of the at least one swingably mounted wheel (5) on an overlying roller carriage.

Abstract: A structure of pallet for stacking pallets with wheels, each pallet has a stop barrier on the three sides of thereof, the remaining one side has a beveled surface tilting downward, two longitudinal grooves are provided on the two mutual opposite longitudinal sides of the pallet. A plurality of insertion holes are provided between the grooves. The pallet has thereunder a fixed wheel set and a movable wheel set, and has on the bottom thereof a plurality of engaging portions and engaging strips. When the pallets are stacked in a mutual orthogonal state, the engaging strips and engaging portions on the bottom of the upper pallet are respectively engaged in the insertion holes and longitudinal grooves on the lower pallet, so that the pallet structure has the function of direction correcting for positioning when in stacking of the pallets, and displacement and falling down of the pallets are surely prevented.

Abstract: A box and dolly system for moving, storing or retrieving goods wherein the box comprises a plurality of substantially upright walls with at least one of the walls having at least two surfaces disposed in an offsetting relationship for forming an overhang and wherein the dolly comprises a plurality of upright walls and a housing adjacent the intersection of each pair of upright walls and with the housing extending from the walls of the dolly such that the dolly may be stacked directly upon another dolly of identical construction with both dollies aligned in the same orientation.

Abstract: A portable, stackable wagon assembly includes a main compartment over which a handle structure is movable to an operational position; the main compartment includes side walls provided with support members for a tray that is insertable into the main compartment to rest on the support members; the tray is provided with at least one partition wall and a handle to facilitate removal from the wagon assembly.
