Benefits of technology

[0006]In one example, the wheel mount interfaces are formed as cup-shaped recesses within the lower shell. For each wheel mount interface in the lower shell, a corresponding cup shaped recess is formed within the upper shell. Each cup-shaped recess includes an opening formed in a bottom of the recess to receive a fastener. The cup-shaped recesses of the upper and lower shells are placed in an overlapping relationship and fasteners are inserted through the openings. The fasteners secure the wheels to the display dolly and also further secure the upper and lower shells together.

Problems solved by technology

The injection molding process is expensive and is not easily adaptable to providing different shapes for the platform.

Embodiment Construction

[0026]FIG. 1 shows a pallet 10 with a wheel retention feature 12 that receives wheels 14 of a dolly 16. The dolly 16 provides a support surface 18 to support a display 20. In the example shown, the wheel retention feature 12 comprises two pairs of upwardly extending rails 22, with each pair of rails 22 being separated by a gap 24 that receives the wheels 14. The rails 22 help prevent movement of the dolly 16 relative to the pallet 10 during shipping.

[0027]Straps (not shown) are also used to secure the display 20 and the dolly 16 to the pallet 10. In the example shown in FIG. 2, a strap retention feature 26 is formed within the dolly 16 at a location over the wheels 14. The strap retention feature 26 in this example comprises a pair of corrugations or grooves 28 that extend across a width of the dolly 16 to receive the straps. Walls 30 of the groove 28 prevent the straps from moving in an axial direction corresponding to a side length of the dolly 16.

Abstract

A display dolly is formed from an upper shell and a lower shell that are thermoformed from first and second sheets of material. The upper and lower shells are formed and attached to each other using a twin-sheet thermoforming process that provides a hollow internal cavity between the shells. The upper shell provides an upper surface to support a display. The lower shell includes wheel mount interfaces to receive wheels such that the display can be moved to a desired location. In one example, the upper shell includes a first plurality of corrugations and the lower shell includes a second plurality of corrugations that extend in a different direction than that of the first plurality of corrugations.

Description

BACKGROUND OF THE INVENTION[0001]Display dollies can be shipped from a product manufacturer with the display already installed on the dolly. The dolly is held fixed in place on a pallet. Straps are used to secure the display and dolly to the pallet. The pallet, dolly, and display are then shipped as a single unit to a store. Once at the store, the straps are cut and a lifting device lifts the dolly and the display from the pallet. The dolly is then placed on a floor and the display is wheeled on the dolly to the desired location.[0002]A typical display dolly includes a support platform with wheels. The platform is formed from injection molded plastic and then the wheels are attached. The injection molding process is expensive and is not easily adaptable to providing different shapes for the platform.SUMMARY OF THE INVENTION[0003]The present invention provides a dolly that movably supports a display.[0004]An example display dolly includes an upper shell and a lower shell that are for...
