Embodiments herein are directed to a mobility device. The mobility device includes a frame, a pair of foot plates, and a base. The frame has a pair of side rails. The pair of foot plates are pivotally attached to the pair of side rails. Each of the pair of foot plates have a transport surface. The base has an upper surface and an opposite lower surface. The lower surface of the base includes at least one receiving cavity that corresponds to a shape of the pair of foot plates. The base is positioned on the transport surface to receive the pair of foot plates within the at least one receiving cavity and is configured to receive a plurality of cargo containers on the upper surface.

A reconfigurable pallet/dolly platform includes a top deck that includes a product support surface and an opposing underside. The underside includes pallet support leg attachment areas for receiving pallet support legs when configured as a pallet, and dolly wheel attachment areas for receiving dolly wheels when configured as a dolly. The product support surface includes pallet support leg receiving areas aligned with the pallet support leg attachment areas and configured to engage the pallet support legs from an identical platform stacked thereon when configured as a pallet. The product support surface also includes dolly wheel receiving areas aligned with the dolly wheel wells and configured to engage the dolly wheels from an identical platform stacked thereon when configured as a dolly. Each dolly wheel receiving area partially overlaps with one of the pallet support leg receiving areas.

In one example, a mother cart is provided that is suitable for transporting a daughter cart. The mother cart includes a base frame having a group of wheels configured to allow the mother cart to be moved. The base frame, in turn, includes a loading bay for receiving the daughter cart, and a support surface for supporting the daughter cart. Finally, the base frame includes a primary restraint mechanism for engaging and securing the daughter cart in the loading bay.

A cart transports items between a controlled environment (e.g., a clean room or an airlock to a clean room) and an uncontrolled environment. The cart has a main body that carries the items, and a removable and interchangeable wheel base assembly. A first wheel base assembly is located in the uncontrolled environment and a second wheel base assembly is located in the controlled environment. The user can push the cart (with the first wheel base assembly) up to the second wheel base assembly at the boundary between the controlled environment and the uncontrolled environment. The user then unlocks the main body from the first wheel base assembly, slides the main body onto the second wheel base assembly, and locks the main body to the second wheel base assembly. An autoclavable storage and transport cart can hold several wheel base assemblies.

A method and apparatus for assisting in removing a wheels-on-ground type daughter cart from a mother cart, and a mother cart incorporating such a method and apparatus, utilize a daughter cart ejector apparatus mounted on a mother cart and having a selectively actuatable ejector element for urging the daughter cart to move out of engagement with the mother cart in an unloading direction. The ejector element is configured and operatively connected to bear against the daughter cart and apply force in a manner that assists in initiating movement of the daughter cart in the unloading direction and reorienting casters supporting the daughter cart on an underlying surface from a rolling orientation that is generally parallel to a transport direction of the mother cart, to a rolling orientation that is generally transverse to the transport direction and parallel to the unloading direction.

Respective electric drive motors (13a, 13b) drive left and right drive wheels (10a, 10b) having friction brakes, including an electromechanical service brake (31a, 31b) and an auxiliary brake (32a, 32b) mechanically biasing them to a braked state. An elongate handlebar (16) for user control is mounted via a pair of force-sensing couplings (17a, 17b) including a resilient member (18) and a load sensor (19) sensing forces applied by a user to the handlebar and transmitting respective load signals. A controller (37) receives the load signals and controls a current applied to the electric drive motors (13a, 13b) so as to amplify the force sensed by the force-sensing couplings and to generate a torque proportional to a force applied by the user to the handlebar and to actuate an electric release actuator of the auxiliary brake (32a, 32b) when the force applied by the user to the handlebar exceeds a threshold.

A reconfigurable pallet/dolly platform includes a top deck that includes a product support surface and an opposing underside. The underside includes pallet support leg attachment areas for receiving pallet support legs when configured as a pallet, and dolly wheel attachment areas for receiving dolly wheels when configured as a dolly. The product support surface includes pallet support leg receiving areas aligned with the pallet support leg attachment areas and configured to engage the pallet support legs from an identical platform stacked thereon when configured as a pallet. The product support surface also includes dolly wheel receiving areas aligned with the dolly wheel wells and configured to engage the dolly wheels from an identical platform stacked thereon when configured as a dolly.

The present invention provides a dolly having a polygonal-shaped platform having an upper surface, a lower surface, a peripheral edge having four corners, a torus-shaped pocket positioned at each corner and dimensioned to receive a wheel from an adjacent dolly, and a plurality of wheels extending from the lower surface and attached thereto.

An electric vehicle is provided, including: a main body, traveling wheels, a drive assembly and a controller. The traveling wheels are arranged on the main body. The drive assembly is arranged on the main body and includes a hub motor. The hub motor is arranged on the traveling wheels. The controller is used to control the hub motor.

A pallet includes a top deck that includes a product support surface and an opposing underside, and with the product support surface including a pair of pallet support leg receiving areas. A pair of pallet support legs is on the underside of the top deck and aligned with the pallet support leg receiving areas. Each pallet support leg including a center leg section having a first end adjacent the underside of the top deck and a second end opposite the first end, and a pair of leg extensions extending outwards from the second end of the center leg section. An underside of the center leg section and the pair of leg extensions are configured to engage one of the pallet support leg receiving areas of an identical pallet when stacked thereon.
