Abstract: The invention relates to convertible children's fun-car devices, go-carts and wheeled carriers, and provides removable and stowable wheel stands or chocks that allow for convenient conversion of such wheeled carrier devices from typical rolling devices to fixed, stationary play toys for use with infants and toddlers, typically not yet walking. The invention allows for selective resilient or screw placement of the wheel stands on two or more wheels to prevent overall device movement, and also provides that the wheel stands along with their associated wheel may further be entirely folded into the profile of the wheeled device, converting the overall fun-car into a completely flat, ultra thin profile with all parts and wheels still attached. Further, the wheel stands may instead be quickly detached from the wheels and stowed inside a compartment in the carrier device, such as in the simulated trunk or hood area.

Abstract: The application provides unique assembly, shipping, display, nesting and compact stowing methods for compact or convertible “sub-assemblies” for wheelbarrow and cart devices. The wheelbarrow or carrier device “sub-assembly” comprising all or some of the interconnected component parts of the device (except for the tub or base) may be selectively movable and stowable to the inside or underside of the cargo carrier, with the user only being required to move and rapidly secure the sub-assembly frame to the device. The wheelbarrow or cart “sub-assembly” disclosed may be entirely or substantially stowed within the side elevational profile and interior of the carrier device carrier space during shipping, transport or sales display, and/or selectively attached to the underside of the base or tub for shipping or display prior to actual use, by a series of any suitable quick release methods commonly known in the art.

Abstract: Wheeled personal mobility vehicles with extremely thin stowed profiles are provided, which in one embodiment, include a plurality of movable, collapsible wheel axle assemblies which are supported on a support frame and movable between an operative state where the wheels provide rolling support, and a collapsed state where the wheels are moved into the side elevational profile of the device. The embodiment provides for both integrated propulsion and steering linkage to the wheels when they are manually moved into their operative position, along with a collapsible steering mechanism, a support base and at least one collapsible seat. This embodiment may also provide for pedal power, battery, fuel cell or motive power as well as remote control operation.

In the child trailer and cargo carriers, the tow bar, carrier walls and associated parts all fold flat to the device frame, along with the wheel axles and tires.

Abstract: A wheeled carrier device is provided which, in one embodiment, includes a plurality of foldable walls supported on a base member and movable between an erected state wherein the walls define a carrier space and a collapsed state wherein the walls are folded on top of the base member. The carrier device has at least two wheels and a wheel mounting assembly pivotably mounts the wheels on the device on opposite sides thereof such that, in one embodiment, the wheels are movable through 270° from a first, operative position wherein the wheels support the carrier device and a second, inoperative position wherein upon release of a latching mechanism the wheels are folded over on top of the folded walls in the collapsed state thereof. A handle is affixed to the carrier device and is movable between an operative state wherein the handle can be used to pull the carrier device and an inoperative state wherein the handle is stowed in substantially flush relation with the remainder of the carrier.
